[00:00:35] <CaptHindsight> both spring loaded
[00:01:15] <farbro> CaptHindsight: Ok, I'll look into a spring solution then.
[00:01:29] <CaptHindsight> or a 60W laser version
[00:01:38] <CaptHindsight> https://www.youtube.com/watch?v=5w4uQhxpmjo
[00:03:16] <Tom_itx> ok my idea for using these latching relays didn't work
[00:03:35] <farbro> CaptHindsight: Yeah I was thinking about laser but it seems too expensive. I'm looking for a very cheap solution... :)
[00:04:16] <Tom_itx> i thought i might be able to wire on side of the DPDT to feed the 2nd coil to release it but even with a cap on it, it doesn't maintain the voltage long enough to reset the relay
[00:05:40] <Tom_itx> it was kindof a long shot anyway
[00:08:35] <Tom_itx> i might be able to rig some diodes up and make it work but it's hardly worth it
[00:08:59] <renesis> 03:49:54 < PCW> Dont engravers often have a shoe that maintains spindle height
[00:09:23] <renesis> sometimes, my engraving tool holder its a screw on cap so you can set height, dont have it
[00:09:48] <renesis> farbro: i think maybe you are looking for a spring loaded engraving bit holded?
[00:09:51] <renesis> *holder
[00:10:26] <renesis> so you adjust the pressure by either using a stronger spring (or compressing the one you got)
[00:11:14] <renesis> and by how deep youre setting the z (which effectively compresses the spring more if youre not capable of cutting that deep in a single pass due to speed/feed/material)

[00:11:55] -!- asdfasd has quit [Ping timeout: 256 seconds]
[00:12:29] <renesis> so if youre doing glass with a diamond cutter, zero speed, you can assume almost no penetration, you can vary the pressure by how far you go into the work and compress the tool holder spring
[00:13:38] <renesis> if youre doing glass with a rotational cutter, you can use z to full depth, make sure it gets that far with a strong enough speed, and a slow enough feed
[00:14:24] <renesis> or you can set z deeper than your intended depth, and then feed fast enough that at your spindle speed it only cuts as deep as you want with a gicen spring
[00:14:57] <renesis> last way is prob faster than 2nd way

[00:19:11] <tjb1> PetefromTn_: what are they?
[00:19:16] * fluffybitchx was more productive
[00:19:37] <zeeshan|2> nap is good
[00:19:41] <zeeshan|2> now i will be more productive
[00:19:46] <zeeshan|2> i can't decide whether i should fix the power supply first
[00:19:49] <farbro> renesis: Hm, yeah that sounds like a plan. I'm trying to find spring loaded tool holders. This is a lightweight machine so it has to be quite small. I was thinking about using a dremel, but not sure...
[00:19:52] <zeeshan|2> or do wiring on the spindle encoder :)
[00:20:24] <fluffybitchx> you should do the thing that makes what you have work, rather than the thing that makes some possible thing in the future maybe work.
[00:20:36] <renesis> farbro: http://www.2linc.com/engraving_mini_1-4.htm
[00:20:47] <zeeshan|2> lol
[00:20:54] <zeeshan|2> but power suplpy repair can be done in the warmth
[00:20:54] <renesis> kinda pricey, thats the smallest they make, i got mine 1/2 price on ebay
[00:20:57] <zeeshan|2> machine is cold right now!
[00:21:12] <fluffybitchx> get a jacket and/or heater? :P
[00:21:17] <CaptHindsight> Price: $345.00 each In Stock well it is turn key
[00:21:38] <renesis> it doesnt include the nosepiece for setting Z
[00:22:10] <renesis> i followed their speed/feed guide for delrin and steel and got great results both times without the noise piece
[00:22:54] <renesis> it doesnt go quite full depth at their recommended rates, lightest spring, so you can do a second path and get bit more definition
[00:22:58] <renesis> comes with 3 springs
[00:23:02] <farbro> fluffybitchx: Yeah I guess it would be better to just focus on this specific task. That will probably make more sense to my examinators too... (this i a school project)
[00:23:51] <farbro> renesis: Cool, way too expensive for this project though...
[00:23:57] <CaptHindsight> farbro: let us know what grade we got in the class :)
[00:24:26] <renesis> farbro: there are cheaper tool holders if you look around, likely import
[00:24:42] <farbro> CaptHindsight: Haha, I'll reference to you in the report ;)
[00:24:56] <renesis> ive been buying little engraving tools from 2L for a long time, for circuit boards, i like them
[00:25:32] <fluffybitchx> farbro: that was intended for zeeshan, but I'm glad it helps you too. lol
[00:25:43] <renesis> i dont think the toolholder price is as fair as their carbide bits, but half off barely used im happy
[00:26:47] <farbro> fluffybitchx: Haha, yeah it really applies
[00:27:08] <farbro> renesis: Hm ok, I'll look closer

[00:35:22] <renesis> farbro: also consider that with a diamond tip into glass you dont have to actually spin the bit
[00:35:38] <renesis> so you dont really need a high speed engraving holder or even a spindle
[00:36:17] <farbro> renesis: You mean just scratch the surface?
[00:36:21] <renesis> yeah
[00:36:53] <renesis> so you could just do a cylinderical bit holder with a spring behind the bit
[00:37:28] <renesis> and some sort of feature to keep the bit from popping out if you are doing discontinuous cutting
[00:37:38] <farbro> renesis: Oh.. never thought about that. But I guess that requires very high accuracy if you need to have a "filled" area
[00:37:52] <renesis> continuous cutting, you can just push the bit in and clip it when not in use during setup
[00:38:12] <renesis> you can hatch the fill area
[00:38:32] <renesis> instead of trying to cut it completely
[00:39:45] <renesis> https://www.youtube.com/watch?v=HOiBB3xEphk
[00:39:48] <farbro> renesis: interesting!
[00:39:55] <renesis> think this guy used engraving fonts
[00:40:20] <farbro> I didn't realise that thing is not rotating
[00:40:28] <renesis> so the solid fill areas are actually made with a bunch of parallel strokes, basically hatching
[00:41:11] <farbro> Hmm, I wonder what precision is required to make the strokes look invisible
[00:41:16] <renesis> yeah i got a diamond bit along with the toolholder, was pretty amazed how easy it was to scribe my pyrex baking dishes
[00:42:48] <XXCoder> nice
[00:43:08] <XXCoder> my shit dermel comes with em too, I do want to try engrave once I ever get router working
[00:43:10] <renesis> if i price the cutters at retail (they look unused), for a 90d conical half round, a 120d conical, ~1/8" 4 flute endmill, and diamond conical bit, i only paid like $100 for the tool holder
[00:43:39] <fluffybitchx> renesis: wouldn't scribing your pyrex create a stress riser that'll make it crack when being used for any of the myriad of temperature-changing tasks pyrex is used for?
[00:44:08] <renesis> its like 3/16" deep and i did a light line
[00:44:12] <renesis> pretty sure itll be fine
[00:44:17] <XXCoder> tet it
[00:44:19] <renesis> ive made bacon at 400F in it since
[00:44:45] <renesis> not like, a lasagna, but seems fine so im not worried

[00:45:09] <fluffybitchx> (while it's 400F)
[00:45:15] <renesis> in retrospect, i could have used one of the shitty china art glass pipes i have
[00:45:24] <renesis> chinese boro is still probably boro
[00:45:36] <renesis> i wouldnt do that anyway
[00:45:54] <XXCoder> free explosion
[00:46:09] <renesis> its boro itd be fine at normal oven temps
[00:46:37] <fluffybitchx> "art glass pipes" sounds like marijuana accessories.
[00:46:38] <renesis> still wouldnt do it tho, not a great habit
[00:46:48] <XXCoder> interesting video
[00:46:50] <XXCoder> yours?
[00:47:09] <renesis> yes the art is how we differentiate ourselves from freebase cocaine and crack users

[00:47:27] <renesis> tho shelden black science glass looks a lot like tweaker gear
[00:47:46] <XXCoder> spring loaded bit interesting
[00:47:55] <renesis> the price of asian art glass is pretty disgusting tho
[00:48:04] <XXCoder> I assume cnc path is in normal rod form
[00:48:25] <XXCoder> hard to see, is that ball em?
[00:48:37] <renesis> in the youtube?
[00:48:41] <XXCoder> yeah
[00:49:02] <renesis> just whatever the diamond is set into, prob doesnt have flutes so shape doesnt really matter
[00:49:12] <XXCoder> interesting
[00:49:55] <XXCoder> funny how scale looks like
[00:50:03] <renesis> one i got is set into 120deg conical end
[00:50:06] <XXCoder> it looks like normal cup till you HUGE hands come in lol
[00:50:15] <XXCoder> your
[00:50:22] <renesis> haha, i think thats a sherline rotary
[00:50:47] <renesis> so i knew it was pretty little

[01:36:37] <XXCoder> its probably good price

[01:38:08] <CaptHindsight> the dispenser looks like an extruder
[01:38:23] <CaptHindsight> doesn't use compressed air
[01:38:29] <CaptHindsight> that I can see

[01:40:12] <CaptHindsight> it's silver ink so it's expensive compared to copper
[01:40:42] <CaptHindsight> doesn't do vias, but it does let you print more than one layer
[01:40:53] <CaptHindsight> all on one side
[01:41:27] <CaptHindsight> https://ksr-ugc.imgix.net/assets/003/243/854/47a87192eacd45a07169117177c9a542_original.gif?v=1423241911&w=700&h=&fit=max&q=92&s=03d0406267d9cedb8ffe9b380940dbe0

[01:42:53] <CaptHindsight> a 3-axis mill that size is $400 with controller
[01:44:13] <CaptHindsight> minimum trace 9mil or 200um
[01:44:24] <PCW> wonder how well connectors stay on
[01:45:19] <CaptHindsight> if the connectors have solder tabs that you solder from the opposite side or have locking pins they should be ok
[01:45:45] <CaptHindsight> but SMT connectors, not very well unless you add an adhesive
[01:46:04] <PCW> yeah glue when done
[01:46:45] <CaptHindsight> https://s3.amazonaws.com/ksr/assets/003/244/519/eaada282e5e75d9c052036bac9ee193d_large.png?1423249434 printing the insulator so you can have conductors cross over
[01:46:50] <Tom_itx> do you bake the ink when it's done or does it just dry?
[01:47:24] <CaptHindsight> sintering will always improve the conductivity
[01:47:41] <CaptHindsight> but I don't see it in the specs so far
[01:48:14] <CaptHindsight> I wonder how many silver ink patents they are violating?
[01:48:24] <CaptHindsight> it's another mine field
[01:48:38] <PCW> hybrids have been made this way for a long time (though with screen printing)
[01:49:09] <PCW> I wonder if they have resistive paste
[01:49:17] <Tecan> patents have been loosing ground for years. people just design things till someone complains then change it a bit
[01:49:58] <CaptHindsight> they don't mention resistive paste but thats a no brainer to make

[02:34:05] <zeeshan|2> is it okay to put my 200 ohm pull up resistor @ the sensor?
[02:34:10] <zeeshan|2> instead of at the 7i77
[02:34:28] <zeeshan|2> its a bit tight in the 7i77 area :)
[02:36:51] <PetefromTn_> woohoo congrats man... fixed what?
[02:37:06] <zeeshan|2> the burnt supply on the 2 drives that blew

[03:38:48] <cradek> electrically, probably. can you read it fast enough for that to be useful? depends on its resolution and how fast the axis will move.

[03:47:57] <anarchos_> cool. i was thinking of picking up a cheapo encoder for my stepper motors, just as something to do/learn with
[03:48:15] <witnit> fantastic idea, what kind of steppers you going with?
[03:48:52] <witnit> so, you want to use the encoder as a handwheel to jog the machine?
[03:49:43] <anarchos_> no, i want to do a closed loop system that ferror's if anything goes wrong
[03:50:15] <witnit> oh, well it depends again as cradek says. very important about rpms on the encoder
[03:50:21] <anarchos_> yea
[03:50:45] <anarchos_> happen to know what the max sample rate for a paraport is?
[03:50:56] <witnit> im sure there are other boundaries but not many people do closed loops servo via parport that i know of
[03:51:43] <pcw_home> If you just want to detect stalls, a fairly low resolution encoder will do

[03:55:28] <fluffybitchx> bleh! /me is too tired to type
[03:55:34] <witnit> you have a lathe to make bushings?
[03:55:44] <pcw_home> and a parallel port could read it up to ~ as fast as most steppers can spin
[03:56:15] <witnit> or just needs nuts?
[03:56:39] <fluffybitchx> I meant washers. I typed the wrong thing. I just need to go to the hardware store and pick some up.

[03:59:01] <PetefromTn_> thanks to methods idea
[03:59:08] <witnit> nice, what did he come up with?
[03:59:17] <PetefromTn_> both sides of all of them are completely deburred beautifully
[03:59:21] <fluffybitchx> ummm... hddit?leo? the closest word I can make to that is addicted, but that font sure doesn't look like it...
[03:59:48] <PetefromTn_> that is just a few of them there are a LOT more here
[04:00:01] <PetefromTn_> yeah the word is addicted
[04:00:12] <fluffybitchx> also, what are they? lol
[04:01:04] <PetefromTn_> they are a custom lower intake manifold cover for a mazda motor that you put on there when you are doing work on the engine
[04:01:20] <fluffybitchx> ... you mean the type of thing I usually use an old rag for? :P
[04:02:00] <PetefromTn_> yes exactly just to keep shit from falling into the motor....with some class....and an excuse to advertise my customers shop
[04:02:24] <fluffybitchx> lol
[04:02:52] <fluffybitchx> I've never used anything other than rags or shoptowels for such tasks.
[04:03:38] <fluffybitchx> (or luck.)
[04:03:43] <PetefromTn_> yeah well these guys like to do things nice.... you should see the stuff they build. some serious eye candy if you like tuner cars.
[04:04:31] <witnit> I would imagine if you could make the same think for him but do some prototypes have compartments for bolts and a long area for tools to sit in :)
[04:04:43] <witnit> thing* err i cannot type either
[04:05:02] <witnit> so he has a tray that can lock on top of it
[04:05:09] <fluffybitchx> I like tuner cars, where tuner is defined as tuned, modified, radical engine swaps, and things like that. this definition does not include looking like it should hang around mr.t's neck.
[04:08:05] <fluffybitchx> so you shoved an LS1 in the back seat of a compact car using a marine v-drive? now that's a project! covering in shiny chrome pieces isn't tuning. :)
[04:09:08] <witnit> depends on the customer :), ever seen a spoiler on a car that doesnt deserve it? =D
[04:09:10] <PetefromTn_> they are NOT making poser cars there...LOL
[04:09:22] <witnit> hahahahaha PetefromTn_ you get it tho ahahah
[04:09:26] <PetefromTn_> most of the cars have north of 500 HP and many are closer to 1k

[04:11:38] <XXCoder> I doubt it will get 1000% funded, thats 10 million
[04:11:49] <fluffybitchx> I need to help someone with an engine swap project... his xj12 needs a new ls1....
[04:11:49] <XXCoder> er 100,000% I mean
[04:11:51] <witnit> dood angry birds
[04:11:55] <witnit> anything can happen
[04:12:38] <fluffybitchx> the swap was done a while ago... complete aftermarket ram fuel injection system and other shiny bits... but the motor's spun a rod bearing.
[04:14:17] <fluffybitchx> and I need to finish up my engine swap... got a couple engine codes to get rid of (ecu is bitching I didn't hook up its fan controls, for example), and needs an exhaust fabbed.
[04:14:19] <witnit> does anyone know anything about using nutrunners?
[04:14:24] <fluffybitchx> yes
[04:14:27] <witnit> with cnc
[04:14:30] <fluffybitchx> no
[04:14:30] <witnit> =D
[04:14:44] <XXCoder> Jymmm: they need 3 more "acivements" for next one, and easiest I think is 150,000 backers, youtube songs (x5) and probably 100 person picture, all with cat ears
[04:14:57] <witnit> i was thinking about using them for some projects due to cost but, im unsure of their capabilities
[04:15:14] <fluffybitchx> only nutrunners I have are the type either a skilled union worker and/or a chinese 7 year old uses to manually install fasteners to a set torque.
[04:15:15] <witnit> fluffybitchx, what do you know about their backlash and endplay?
[04:15:33] <fluffybitchx> ... huh? we must be thinking of different kinds of nutrunners.
[04:15:42] <witnit> i was thinking of the programmable kind
[04:16:10] <witnit> but i only ever seen them lying in corners of dark shops
[04:16:21] <fluffybitchx> a nutrunner is a pneumatic tool, often similar in construction to an impact wrench, to rapidly install fasteners to a repeatable torque.
[04:18:40] <witnit> http://www.ebay.com/itm/Atlas-Copco-Model-ETD-DS7-30-10ST-nutrunner-with-cable-used-/291374760877?pt=LH_DefaultDomain_0&hash=item43d74a03ad
[04:18:45] <witnit> something similar to this
[04:18:47] <fluffybitchx> http://www.ingersollrandproducts.com/am-en/products/tools/fastening/air-nutrunners/handheld-nutrunners/adjustable-cushion-clutch-nutrunners/7-series I have the old version of one of those... it's like a cordless screwdriver, but about fifty times faster, and impact so you don't need to fight the torque. :)

[04:19:35] <fluffybitchx> I've never seen an electric one... no idea how they operate.
[04:20:30] <fluffybitchx> if they're just electric drive to a similar impact mechanism, "backlash" is about a turn, endplay and sideplay depend on how worn the bearings are...
[04:20:41] <witnit> I may pick some old ones up and if i can get it running on a mesa card i will sure tell everyone how much I do and dont like them
[04:21:23] <witnit> I will just have to pick some up try things with them
[04:21:38] -!- swingley_ has quit [Ping timeout: 245 seconds]
[04:21:38] <fluffybitchx> on the air ones, the torque is set with a mechanical clutch or shutoff mechanism.
[04:21:47] <witnit> I really want them because they are so compact
[04:22:01] <fluffybitchx> what're you planning on using it for?
[04:22:45] <witnit> i have a few machines which i would like to put a live tooling in from the rear at low cost
[04:23:25] <fluffybitchx> eh, might not work well. at least most of the air ones are impact. don't know about the electrics...
[04:23:56] <witnit> http://img.directindustry.com/images_di/photo-g/multi-spindle-drilling-head-26530-3303705.jpg
[04:24:01] <fluffybitchx> and they're usually plain bushes instead of ball as there's no sideloading in normal use
[04:24:03] <witnit> in those holes
[04:25:10] <PetefromTn_> witnit what machines are you speaking of
[04:25:15] <witnit> quick swappable servos units with the tooling and collet preset out side of the machine and you slide the servo and cutting tool out from the rear
[04:25:17] <witnit> davenport
[04:25:54] <witnit> it would be for a stationary head, the picture shows the the revolving side there.
[04:26:02] <witnit> but the part looks similar

[04:29:38] <PetefromTn_> well you'd be the exception then

[04:30:39] <PetefromTn_> no thanks I will just enjoy a well made video production whenever possible
[04:31:11] <XXCoder> PetefromTn_: basically what I'm saying is that videos is pointless because theres always information in audio that I cannot understand
[04:31:27] <fluffybitchx> it's a radio with no moving parts. video is not going to give any information that can't be provided much better with text and a couple images.
[04:32:07] <PetefromTn_> XXCoder for your instance I can understand it. but there is no way text and pictures can tell a story as well as a well made video
[04:32:43] <XXCoder> well made maybe dunno
[04:32:50] <fluffybitchx> you're right, there's no way text and pictures can be as slow and annoying as listening to someone talk when you could just read it.
[04:33:21] <fluffybitchx> for complex mechanical motions and such, video is an excellent tool. but we're talking a device with no moving parts.

[10:52:15] <RyanS> anyone used round insert face mills?
[10:52:29] <Swapper> yep got one 1 week ago
[10:53:54] -!- MattyMatt [MattyMatt!~matt@cpc12-birk7-2-0-cust211.1-3.cable.virginm.net] has joined #linuxcnc
[10:54:00] <Swapper> Anything special your wondering ?
[10:57:15] <RyanS> better for benchtop mills (BF30) than 90° square facemills? ie less spindle power reqiured ?
[10:57:58] <Swapper> i have a square facemill and i cant get as good surface finish, get a step between passes
[10:58:29] <Swapper> probaly a tramming issue to some extent
[10:58:57] <Swapper> but the round incert facemill gets real good finish even on multipass
[10:59:31] <RyanS> so that's a similar to round nose/radius lathe tools--good finish?
[10:59:37] <Swapper> so if your not intend to use the 90° one to hog out material get the round incert
[11:00:26] <RyanS> Probably use endmill for roughing
[11:00:26] <Swapper> i used my 90° to do adaptive clearing to remove a lot of material fast and for that it works very good. A shower of chips
[11:00:54] <Swapper> but for facing i would go round or angled incerts like the tormach superfly
[11:01:50] <RyanS> so angled and round for finishing
[11:02:32] <Swapper> thats my belief after testing
[11:03:20] <Swapper> spindlepower wise i dont think you will notice any differance, dimeter of cutter makes the biggest differance
[11:03:42] <Swapper> i use a 50mm one since i dont have as much low speed torque
[11:03:59] <Swapper> and with cnc multipasses is no problem
[11:04:15] <Swapper> and im not facing motor block tops :)
[11:05:16] <RyanS> seems too ambitious to claims max 75mm facemills here: http://www.optimum-machines.com/products/milling-machines/bf30vario00/index.html
[11:06:01] <Swapper> all depend on speed and engagement, 0.2mm full width would probably be possible with a 75,,
[11:06:20] <Swapper> speeds and feeds
[11:06:47] <Swapper> do you still use the gearbox ?
[11:07:17] <Swapper> the low speed torque makes differance on bigger cutters since they need to turn slower then smaller
[11:07:47] <RyanS> I haven't received the machine yet. just ordering cutters
[11:09:02] <Swapper> ok
[11:10:08] <Swapper> i got my round incerted facemill with incerts made for cutting aluminium, they are polished and have a positive cutting angle to them that makes good surfacefinish
[11:10:21] <Swapper> so try getting both types of incerts for it
[11:12:10] <Swapper> http://zero-divide.net/?page=fswizard&shell_id=199
[11:12:28] <Swapper> you can play some with the size of the cutter and the HP req
[11:12:33] <Swapper> and torque
[11:12:44] <Swapper> off to lunch
[11:12:47] <Swapper> for me

[11:55:39] <miss0r> I am trying to figure out weather to convert my manual arboga u2508 mill to CNC or not. I have no issue replacing the old threaded rods in the X-Y table with a ballnut system. My issue if what to do with the Z-axis. as you can see on this quite nice drawing: http://www.practicalmachinist.com/vb/attachments/f38/19494d1264407546-drill-press-geared-head-vs-belt-driven-sales-blurb-arboga-u2508-lo-res.jpg
[11:57:04] <miss0r> The two possibilities, the way I see it, are: the handle on the back of the tower lifting the entiere colum and machine part or the handle for the drill bit lowering, on the front. The problem is: both places have a pretty large amount of backlash, which I cannot figure out how to get rid of. Do you guys have any suggestions?
[11:57:43] <archivist_herron> I dont see round column as suitable
[11:58:35] <miss0r> indeed. But it's all i've got - can it be done?
[11:58:38] <archivist_herron> what stops any rotation of the column when in use
[11:59:29] <miss0r> the linear gear bolted to the outside of the column is bolted in both ends and fits into a slot
[11:59:48] <miss0r> pretty tightly actualy. it won't go anywhere
[12:00:33] <archivist_herron> grab the head rotate while unclamped, how much play
[12:00:36] <miss0r> you can see it here: http://www.lathes.co.uk/arboga/img5.gif
[12:01:28] <miss0r> nothing
[12:02:43] <miss0r> it has the same system for removing play as the x-y table has it(some fort of hard metal, wedged in between and two bolts to loosen/tighten it)
[12:04:09] <archivist_herron> have you googled to find anyone else who has done it?
[12:04:50] <miss0r> yep. I can't seem to find anything on this particular construction.
[12:04:51] <renesis> how much play is there on the X and Y wheels?
[12:05:13] <renesis> if the column isnt an issue, backlash might be
[12:05:33] <miss0r> renesis: I am replacing the old threaded rods with ballnut axles
[12:05:36] <renesis> manual machines, backlash doesnt matter so it sucks
[12:05:49] <renesis> k
[12:06:08] -!- karavanjo has quit [Ping timeout: 250 seconds]
[12:11:41] <miss0r> archivist_herron: I am having a vision: What if I attach an external ballnut+rod to the front of the mill, connected to the end of the spindle. I wonder if that will be stable enough
[12:12:40] <archivist_herron> I think that is one heavy head :)
[12:12:45] -!- danylevskyi_ has quit [Ping timeout: 244 seconds]
[12:13:11] <miss0r> indeed. But; What if I were just to move the spindle ud and down?
[12:13:40] <miss0r> disengaging the manual system and sort of "hang" the spindle on an external threaded rod?
[12:13:55] <archivist_herron> that may be the best bet, can you gear to the handle mechanism
[12:14:40] <miss0r> I don't understand the question :/
[12:15:25] <archivist_herron> the handle probably gears into a rack on the spindle
[12:16:42] <miss0r> yes. And I even have a "worm drive?" with a turnable handle in the front. It would be easy to add a stepper there, but the backlash if pretty big. I was playing with the thought of just adding a downward forcing spring to keep it tensioned, but I fear that will not do.
[12:16:44] <archivist_herron> if it has a spring return that will/should deal with backlash
[12:17:14] <miss0r> but you think it will? :)
[12:17:34] <archivist_herron> if you do it right :)
[12:18:14] <miss0r> It has a return spring. I am thinking of reversing that, since most cutters will try to drag the spindle down.
[12:18:18] <archivist_herron> I have seen plenty of machines that use a spring for backlash control, usually not cnc though
[12:20:12] <miss0r> One will have to learn the hard way :) one last question; since I have little experience with building/converting mills, I am at a loss at to how powerfull the steppers need to be - and I don't want to just run out and buy something massively overexpensive, when I could have handles it with alot smaller; question part: What size would you use for this job ?
[12:21:01] <miss0r> i.e. n-m or oz-in size would you reccomend?
[12:21:29] <archivist_herron> measure the torque, go over sized to avoid lost steps
[12:21:56] <archivist_herron> far to easy to undersize
[12:22:01] <renesis> if its going to be open loop step go big, make sure they will spin fast enough
[12:22:12] <miss0r> Indeed. But I don't have a torque measuering device or anything
[12:22:14] <Swapper> yea, big steppers need high voltage
[12:22:28] <Swapper> so you cant go wrong with high voltage stepper drivers
[12:22:38] <archivist_herron> a bit of wood and a weight
[12:22:40] <Swapper> 70v or more i would say
[12:23:05] <renesis> if you go nema23 youre prob going to want the biggest nema23
[12:23:24] <archivist_herron> I made my mill with undersized motors. I hate the failures later
[12:23:41] <miss0r> thats pretty big: I need to add, even when ajusted quited tightly and absolutly no play available in the x-y table, it is quite easy to move with the handles
[12:24:14] <renesis> btw http://www.avclub.com/article/heres-video-jon-stewart-announcing-hell-leave-dail-215086
[12:24:18] <archivist_herron> until you plonk a large casting on the table
[12:24:19] <renesis> obviously to run in 2016
[12:24:22] <miss0r> i.e. I can turn the knoibs with my littlefinger
[12:25:11] <miss0r> archivist: indeed. This is also true when I add a 120lb rotary table.
[12:25:32] <miss0r> and, might I add, it is hell lifting that thing in place
[12:25:46] <archivist_herron> my rotaries unbalanced the weight on the slides causing a lot of extra friction on the XY

[12:34:15] <miss0r> That is true, as big as it is, as empty is my pockets ;)
[12:34:20] <Swapper> i ran that type of stepper drivers on a X2 mini mill and that where about right
[12:35:10] <miss0r> the ones I posted a link about?
[12:35:18] <miss0r> or the one you posted?
[12:36:14] <Swapper> the one i posted
[12:36:46] <miss0r> isn't an X2 small compared to mine?
[12:36:54] <Swapper> yea real small
[12:37:05] <Swapper> i where probably a bit vague
[12:37:06] <Swapper> sorry
[12:37:20] <Swapper> the stepper drivers would work good on your size mill with the right motors
[12:37:34] <miss0r> What motors would you reccomend then?
[12:37:45] <miss0r> Then I can start crying about the price :)
[12:38:42] <Swapper> for z axis geared right http://www.jbcnc.se/product_info.php?cPath=2&products_id=182 or http://www.jbcnc.se/product_info.php?cPath=2&products_id=343
[12:38:46] <Swapper> cant say for shure
[12:39:25] <Swapper> for inspiration check http://elektronikforumet.com/ and cnczone for conversions, lots of discussions regarding sizing of steppers / servos
[12:39:27] <miss0r> 14nm is pretty massive: I have a worm drive on the stepper there
[12:39:37] <miss0r> alright, Thanks
[12:39:49] <Swapper> arent you going to replace all axises with ballscrews ?
[12:40:08] <Swapper> then you can gear it 1:3 or what suits
[12:43:15] <Swapper> But remember bigger steppers = slower if voltage is not kept high enough
[12:43:24] <Swapper> before they looses steps
[12:45:11] <miss0r> I wan't planning on gearing it honnestly. I was planning on running the ballscrews directly with the steppers

[13:22:06] <__rob> anyone used Autodesk Inventor HSM
[13:22:41] <__rob> basically, my end mill is supposed to be 4mm, but I've been cutting test holes for a 17.1mm diameter bearing and it doesn't fit
[13:22:55] <__rob> I stuck the calipers on the tool and the widest part seems to be 3.92mm
[13:23:28] <__rob> is this kind of tolerance normal in an end mill, or should it be exactly 4mm ?
[13:24:57] <Jymmm> Is it one of those lil 1/8" end mills with the colored ring on it?

[13:37:32] <__rob> so actually... looking at this..http://www.proxxon.com/us/micromot/34104-accessories.php
[13:37:35] <__rob> its all in inches
[13:37:40] <__rob> for the end mill set
[13:38:03] <__rob> although it has in brackets (mm)
[13:38:09] <__rob> which is nonsense
[13:38:30] <__rob> if its 5/32 inches, its not 4mm
[13:39:22] <__rob> archivist_herron, i've not allowed for backlash, but it seems pretty tight
[13:39:26] <__rob> dunno how to calibrate for that
[13:40:00] <Rab> Proxxon is german, I'd more expect them to sell a 4mm end mill as 5/32.
[13:40:18] <archivist_herron> you need to measure
[13:40:24] <__rob> yea, well calipers (crappy ones) say 3.94
[13:40:44] <archivist_herron> I mean the backlash
[13:40:45] <Jymmm> 0.15625" == 3.96875mm
[13:41:02] <_methods> that's what cutter compensation is for
[13:41:10] <Rab> __rob, what's your material? And have you tried running the job again on the same fixed workpiece as a kind of finishing pass? That HSS tool may be deflecting under load.
[13:41:17] <__rob> aluminium
[13:41:31] <Rab> What is your depth of cut?
[13:41:31] <archivist_herron> the machine can be deflecting too
[13:41:37] <__rob> 0.5mm,
[13:41:41] <_methods> lol
[13:41:43] <__rob> tried with 0.2 aswell
[13:41:44] <_methods> not deflection
[13:41:45] <_methods> hehe
[13:42:03] <_methods> are you using cutter comp?
[13:42:08] <__rob> no
[13:42:14] <_methods> well........
[13:42:19] <Rab> __rob, tried milling a slot and measuring the slot?
[13:42:27] <__rob> no, I will do some more tests
[13:42:32] <__rob> only just got it working
[13:44:34] <Rab> What's the actual diameter of the cut hole?
[13:44:58] <archivist_herron> is the hole round
[13:48:31] <__rob> 17.1mm
[13:48:42] <__rob> yea, looks pretty nice
[13:49:10] <__rob> just finished another , with the cutter set to 3.9mm and it looks like the bearing fits.. with a few finishing passes

[13:50:01] <Rab> 17.1mm bearing and a 17.1mm hole, sounds like an interference fit. ^_^
[13:50:34] <Jymmm> Nothing a lil LN2 and a torch couldn't resolve
[13:51:18] <__rob> interference fit ?
[13:51:20] <__rob> https://www.youtube.com/watch?v=YdspVQ5G2YM
[13:51:23] <__rob> thats the setup
[13:53:48] <Rab> __rob, if the hole and the bearing are exactly the same size, friction will require pressing the bearing in. The hole actually needs to be a few thou oversize for a slip fit.
[13:54:25] -!- swingley has quit [Ping timeout: 255 seconds]
[13:54:45] <__rob> yea, well bearing is 17 exactly
[13:54:52] <__rob> the hole has come out 17.6
[13:55:05] <Rab> And of course deflection of the tool or machine, or many other factors, could result in the hole being slightly large or small or oblong.
[13:55:07] <__rob> bit hard to say with these calipers, I can move it 0.04 either way with pushing harder
[13:55:39] <Rab> Don't push on your calipers.
[13:56:50] <__rob> ok
[13:57:02] <Jymmm> Don't use the force Luke!
[13:57:06] <__rob> other questions was about a chamfer on the edge
[13:57:17] <__rob> I was using an NC drill for it
[13:57:26] <__rob> dunno if theres a better option, seems to have worked
[13:57:38] <Rab> You can make $500 calipers deflect .04mm, but you had better rather not.
[13:58:42] <__rob> the problem with the chamfer with Inventor HSM is that I cant have the chamfter on the part in inventor, as I need to use 2d Coutour and pick the contour that isn't there if I have the actual chamfer applied within inventor
[13:59:04] <__rob> dunno if anyone knows how you can have both
[13:59:54] <__rob> and also I would like to know if an NC drill is ok for this purpose
[14:00:11] <__rob> http://www.traderscity.com/board/userpix29/20327-solid-carbide-nc-spotting-drills-1.jpg
[14:00:14] <__rob> one of these things
[14:02:16] -!- karavanjo has quit [Ping timeout: 250 seconds]
[14:05:50] <_methods> you can use those spotting drill for that but i prefer not to
[14:06:39] <_methods> http://www.shars.com/products/view/19944/18_Single_End_4_Flute_Solid_Carbide_Chamfer_Mill_100_Degree
[14:07:11] <_methods> http://www.shars.com/product_categories/view/807222530/90_Degree
[14:07:39] <_methods> or you can use an insert chamfer mill
[14:07:46] <_methods> on inserted spotting drill
[14:07:59] <_methods> depends on how big of a chamfer and how big of a wallet you have
[14:09:03] <_methods> and you can have the chamfer in your model you just need to select the geometry you want and use a contour path and offset the depth to whatever you want to make the chamfer the size you need
[14:10:32] <__rob> yea, well this is 0.5mm all around
[14:10:38] <__rob> just makes the part look neat imo
[14:10:43] <_methods> yeah
[14:10:52] <_methods> chamfers and fillets are good
[14:11:23] <_methods> you'll run into the same issue with fillets also
[14:14:17] -!- Valen has quit [Quit: Leaving.]
[14:14:23] <__rob> ahhh, offset, found it
[14:14:24] <__rob> thank
[14:14:25] <__rob> s
[14:15:25] <_methods> if you're not using cutter comp what are you using?
[14:15:38] <_methods> you're letting the computer generate the path with comp?

[14:16:31] <_methods> you'll probably need to lie to it about the chamfer tool diameter if you use the final circle dia or draw a new circle inset for the dist of your chamfer
[14:18:06] -!- FinboySlick [FinboySlick!~shark@74.117.40.10] has joined #linuxcnc
[14:19:36] <__rob> well yea, inventor is set to computer
[14:20:01] <__rob> for the compensation mode
[14:20:13] <__rob> seems to take into account the cutter size
[14:20:21] <__rob> surely thats all that is needed ?
[14:20:31] <_methods> it will but you will have no option to compensate at the machine
[14:20:39] <_methods> i set mine to wear personally
[14:20:55] -!- FrozenCow has quit [Quit: Leaving]
[14:20:57] <_methods> what's the other option
[14:21:03] <_methods> wear, computer and something else
[14:21:32] <_methods> the other one you have to put the actual cutter dia into your tool table
[14:21:43] <_methods> i just put corrections into the wear column in my tool table
[14:22:07] <__rob> http://snag.gy/nB5jI.jpg
[14:22:10] <__rob> thats the optiosn
[14:22:13] <_methods> i just do that from habit from working at a high production place that wanted to limit operator entry
[14:22:35] <_methods> yeah incontrol
[14:22:44] <_methods> you'd need to enter the tool dia
[14:22:46] <_methods> and tool wear
[14:23:03] <_methods> but wear you just insert the wear amount only
[14:23:09] <__rob> is that in inventor still?
[14:23:11] <_methods> no need to insert teh tool dia
[14:23:11] <__rob> the wear setting ?
[14:23:22] <_methods> i see it there in that pic you sent me
[14:23:26] <_methods> wear and inverse wear
[14:23:31] -!- amiri has quit [Remote host closed the connection]
[14:23:52] <__rob> yea, just confused about the point
[14:23:59] <_methods> IN control gives you the most control
[14:24:10] <_methods> you can swap out any tool and get good paths
[14:24:13] <__rob> yea, but overall its the same as just setting the tool diameter
[14:24:16] <__rob> ahh right
[14:24:18] <_methods> with just wear you can get into some cutter comp issues
[14:24:30] <_methods> if you put in too small or too large of a tool
[14:25:49] <_methods> but for maximum choice i'd use in control just know that you need to enter your tool dia into the tool table

[16:41:43] <_methods> hahah
[16:41:49] <_methods> touche
[16:41:57] <_methods> all i wanted was a damn sewing machine
[16:42:28] <malcom2073> My mom just spent $4k on a new sewing machine, damn thing has a xy table for embroidery
[16:42:36] <malcom2073> Pretty slick stuff
[16:43:10] <_methods> i just need an industrial one that can sew nylon webbing and stuff
[16:43:17] <_methods> heavy weight material
[16:44:10] <__rob> _methods: if i type in the exact cutter sizes and dotn push the calipers it seems exactly right, just dont a few more tests
[16:44:12] <__rob> thanks for the help
[16:44:20] <_methods> np
[16:45:30] <_methods> that's what cutter comp is good for lol
[16:45:42] <_methods> besides making you pull your hair out when it's not working right
[16:46:19] <_methods> well i guess cutter comp is always working right
[16:46:28] <_methods> i just put stupid stuff in that makes it not work
[16:47:12] <toast-work> i wouldn't call a consew "just a damn sewing machine"
[16:47:18] <toast-work> i'd still bid on it for 300
[16:47:19] <mozmck> _methods: you can sew pretty heavy stuff with a good home machine even.
[16:47:25] <_methods> yeah i'm thinking about it
[16:47:31] <mozmck> Is it walking foot?
[16:47:31] <_methods> it's still going up though
[16:47:44] <_methods> it's a 206
[16:47:44] <toast-work> I'm dumb in that i got a serger first and kept my home-grade straight stitch machine
[16:47:52] <toast-work> i should have got a zigzag machine instead
[16:48:19] <_methods> there's a juki that goes up in a few days i'll try and get
[16:48:26] <_methods> i think juki305
[16:49:11] <_methods> oh nm
[16:49:18] <_methods> juki lk-1850
[16:49:53] <PetefromTn_> I don't know much about sewing machines but I always wanted a heavy duty one for upholstery and webbing/leather stuff
[16:50:00] <_methods> yeah
[16:50:03] <_methods> that's what i want it for
[16:50:16] <mozmck> consew 206 RB-5 is triple feed - nice.
[16:50:22] <_methods> i want to make a prototype tent that goes into my tacoma bed rails
[16:50:37] <PetefromTn_> Ooh that is nice..
[16:50:42] <_methods> yeah
[16:50:48] <PetefromTn_> I would LOVE to be able to make a softtop for my bronco
[16:51:13] <PetefromTn_> they make nice ones but they cost over $800.00
[16:51:29] <mozmck> you can do that with a decent home machine. a Pfaff 1200 series will do it - most any older sewing machine
[16:51:36] <PetefromTn_> and I don't mean drilling it full of button holes
[16:51:42] <_methods> yeah the older direct drive pfaff and singers
[16:51:46] <mozmck> I know because my wife does a lot of that stuff.
[16:51:58] <_methods> but if i can get a consew or juki for $200 and under
[16:52:00] <_methods> i'm takin it
[16:52:08] <PetefromTn_> thats pretty cheap
[16:52:13] <_methods> i'm cheap lol
[16:52:18] <_methods> i just watch auctions
[16:52:20] <PetefromTn_> yeah me too ;)
[16:52:22] <_methods> sooner or later i'll get one
[16:52:23] <mozmck> We do have a couple of walking foot machines and several industrial, but she can do most of it on a home machine.
[16:52:53] <mozmck> Yeah, for a good compound feed machine $200 will be hard to find
[16:53:03] <_methods> that's why i watch auctions
[16:53:05] <_methods> lots of them lol
[16:53:08] <PetefromTn_> I tried to do some canvas on my wife's machine and while it did it I almost broke it and now she is like NEVER AGAIN!~
[16:53:10] <_methods> you never know what you can get
[16:53:31] <mozmck> :) I'm not stranger to auctions.
[16:54:02] <mozmck> Most of my industrial machines have cost me $100 or less with table and motor. But my pfaff 145 was about $400
[16:54:03] <PetefromTn_> I guess you never did find me that $100.00 fourth axis then hehehe
[16:54:03] <_methods> if you're patient and watchful you can get some great deals
[16:54:18] <_methods> haha no i'm watching as always
[16:54:25] <_methods> there is an auction tomorrow i'm going to miss
[16:54:34] <_methods> gotta go to customer all day
[16:54:41] <PetefromTn_> that will be the one that has it LOL
[16:54:47] <CaptHindsight> who makes very narrow knitting needles?
[16:54:52] <mozmck> The problem with auctions is that often things go way too high.
[16:54:59] <PetefromTn_> oh yeah
[16:55:05] <PetefromTn_> I have seen that firsthand
[16:55:06] <mozmck> I often get better deals at junk shops and craigslist.
[16:55:14] <_methods> yeah it depends on who's at the auction
[16:55:25] <mozmck> Yep, I've watched many a thing sell higher than new cost.
[16:55:31] <PetefromTn_> my brother in law took me to an local auction awhile ago
[16:55:31] <_methods> i got a coolant recycler at an auction about 2 years ago for $150
[16:55:37] <_methods> it's a $20k recycler
[16:55:45] <_methods> no one knew what it was at the auction
[16:55:51] <CaptHindsight> yes, odd things go for very low

[16:56:22] <malcom2073> Around here I have to fight the amish for linear actuators. They take them apart and use the bearings to make wood lathe sliders heh

[16:56:34] <malcom2073> It's actually pretty cool what they do with them, but a total waste of the technology
[16:56:37] <mozmck> Yep, can happen. I bought an Asymtek fluid dispensing machine that we still use to dispense solder paste on prototype boards for $150
[16:56:41] <CaptHindsight> _methods: refrigerant recycler?
[16:56:47] <_methods> no coolant
[16:56:52] <_methods> milling machine coolant
[16:57:10] <_methods> you put a hose in the tank and it pulls all the coolant out, filters it, then you pump it back in
[16:57:20] <PetefromTn_> OOh I need one of those
[16:57:30] <_methods> yah it's the bomb
[16:57:40] <_methods> the last shop i was at had it all built into the shop
[16:57:46] <PetefromTn_> jeez man you got all the cool toys heh
[16:57:47] <_methods> they had a central recycler
[16:58:12] <_methods> and spigots at machine that you just poured coolant into yoru machine when you needed fresh coolant
[16:58:25] <PetefromTn_> coolant on tap
[16:58:26] <Connor> I've been looking for a lathe on CL for months now.. no luck.
[16:58:44] <mozmck> Connor: what kind of lathe?
[16:58:47] <mozmck> cnc?
[16:58:48] <_methods> yeah coolant is a huge time waster for operators
[16:59:01] <_methods> if they have to mix it and whatnot
[16:59:05] <Connor> So, I'm thinking of the 11x26 G9972Z or the 10x22 G0602
[16:59:34] <mozmck> there are quite a few in the dallas area - I don't know where you are though.

[17:04:03] <Connor> Only one of it's size that I've found that has powered crossfeed.
[17:04:42] <PetefromTn_> man I paid less than that for my 12x36 jeez
[17:05:04] <Connor> PetefromTn_: Yes, and you told me the story on how you got it too... I'm not so lucky on deals these days.
[17:05:22] <PetefromTn_> yeah but they are out there
[17:05:33] <PetefromTn_> decide what you REALLY want and don't settle
[17:05:42] <Connor> and, it might be too large.. I need to go measure my workbench.. this might be a complete pipe dream.
[17:05:44] <PetefromTn_> post ads on craigslist wanting

[17:07:37] <Connor> freaking little mini lathe motor is stalling out on startup.. not sure why.
[17:07:54] <PetefromTn_> because it's a mini lathe hehe
[17:08:07] <Connor> No.. I think the motor is toast.
[17:08:15] <PetefromTn_> damn that sucks
[17:08:22] <SpeedEvil> It's probably not designed for the massive torque of startup.
[17:08:24] <Connor> I may have ran it too fast, or too hot.
[17:08:41] <Connor> SpeedEvil: What, just spinning the chuck ?
[17:09:05] <SpeedEvil> :)
[17:09:27] <Connor> having the same issue with my 4x6 belt sander too.. which is a HF deal, so, that Doesn't surprise me..
[17:09:31] <PetefromTn_> and ya gotta be willing to go get the machine when you find it too..
[17:10:56] <malcom2073> I've burned out HF motors before, had a horizontal bandsaw I burned the motor out on just cutting through some 4" square stock. Wound up replacing the motor
[17:11:00] <Connor> Well.. First Priority is getting the Kitchen back together.. I'm slowly working on it. I got the drain plumbing done. Now I need to rip out a tad more sheet rock and deal with the supply plumbing.. and then re-sheetrock and install cabinets.
[17:12:17] <PetefromTn_> yeah my 4x6 bandsaw puked a motor once
[17:12:33] <PetefromTn_> I put an industrial 1hp motor on it from tractor supply
[17:12:56] <PetefromTn_> then I got the 7x12 and sold it with a smile on my face
[17:13:45] <PetefromTn_> I used to have one of those delta drum sanders here for making cabinet doors etc.
[17:13:48] <jdh> my 4x6 is still on the stock blade
[17:14:06] <Connor> jdh: That's because you don't do much with it. :)
[17:14:08] <PetefromTn_> that thing would come in real handy doing brushed finishes on aluminum parts I think wish I had never sold it.
[17:14:13] <Connor> *poke* :)
[17:14:33] <PetefromTn_> wow the original blade?
[17:14:46] <Connor> I have a little 1" Belt sander from HF too..
[17:14:47] <PetefromTn_> I don't think that thing lasted more than a dozen cuts
[17:15:07] <jdh> I don't do much with it. 98% aluminum
[17:15:40] <PetefromTn_> yeah but still that is amazing for one of those chinese blades. they suck in my experience LOL
[17:16:12] <PetefromTn_> lennox or starrett are a million times better
[17:16:20] <jdh> I have a better bimetal one waiting
[17:16:23] <PetefromTn_> and not really that much more expensive
[17:16:46] <PetefromTn_> the blade in my saw right now has a kink in it. It is really annoying
[17:16:56] <PetefromTn_> but it still cuts so good I hate to swap it for the new one
[17:17:11] <PetefromTn_> I may take it out and try to beat the kink out or something
[17:17:45] <PetefromTn_> it got caught in a piece of tubing when the vise slipped because I did not tighten it down properly DOh

[17:34:08] <GMendez> what can i do to add the sStepGen Dir#4 on my p3 connector
[17:34:26] <pcw_home> what configuration?
[17:34:45] <GMendez> factory
[17:35:06] <GMendez> never flashed the board as far as i know
[17:35:26] <pcw_home> many standard configurations use s stepgen for a chargepump (so it has no dir pin)
[17:35:55] <pcw_home> AFAICR G540 MX3660 are like this
[17:35:57] <GMendez> dont get it. I have dir for 4 other axis
[17:36:49] <GMendez> i used pnconf to get a model HAL file and I hve edited the file to add 2 others axis , limit etc...
[17:37:21] <pcw_home> you may have dir for 64 axis but its still possible some DIR pins are missing if they are intended for use as charge pumps
[17:37:47] <GMendez> well I'm okay with that so
[17:37:56] <Connor> PetefromTn_: Check your PM
[17:38:03] <GMendez> what can i do to add the missing Dir to be mapped on my P3 connector
[17:38:12] <GMendez> (thanks a lot btw)
[17:38:54] <pcw_home> that requires a custom bitfile (or you need to find a standard bitfile that has 4 full stepgens on P3)
[17:40:02] <Connor> pcw_home: You need to come up with a bitfile wizard..
[17:40:12] <GMendez> umm never heard of bitfile. I have the source code of my current mesa firmware (send by Mesa) Perphase i can edit and flash the code
[17:40:32] <pcw_home> for example the probrfx2 pinout has 4 stepgens
[17:40:33] <Connor> GMendez: PCW = Mesa :)
[17:40:54] <pcw_home> well Mesa >PCW
[17:41:22] <pcw_home> but I am the chief bottlewasher
[17:41:24] <GMendez> i have 4 full step gen, and 1more without Dir
[17:41:28] <malcom2073> Has anyone noticed google results for practicalmachinest randomly redirecting to a... less than legitimate and not very work safe website on occasion? I've noticed it on several different PC's, at several different locations now over the past few months.
[17:41:50] <malcom2073> But then if I go to the same link again, it works and goes to PM as expected
[17:41:58] <cradek> are you sometimes misspelling it as machinest?
[17:42:03] <Connor> malcom2073: Probably have some sort of malware on the site

[17:43:32] <cradek> practicalmachinist.com loads fine for me
[17:44:17] <malcom2073> It loads fine 99% of the time, but occasionally it'll redirect
[17:44:37] <malcom2073> I've only noticed the redirect when clicking on a link off of google for PM
[17:45:09] <malcom2073> I figured it may be malware, but it's done it on three PC's now, two of which aren't windows

[18:44:03] <_methods> forget that a tool is loaded?
[18:44:51] <_methods> you just want it to do a toolchange?
[18:44:56] <dirty_d> right
[18:45:02] <_methods> just give it a m6
[18:45:06] <_methods> with no tool callout
[18:45:38] <_methods> it should do a toolchange to whatever is in pot
[18:46:23] <dirty_d> if i re-run the program it no longer pauses after the M6
[18:46:33] <_methods> is it just a m6
[18:46:35] <dirty_d> it only does the first time its run
[18:46:40] <_methods> or do you have a T on it
[18:47:00] <_methods> you could always just use a m1
[18:47:01] <dirty_d> just M06
[18:47:08] <_methods> if you just want a pause
[18:47:24] <_methods> or m00
[18:47:56] <dirty_d> hmm, the m01 didnt do anything
[18:48:03] <_methods> it's option stop
[18:48:09] <_methods> you hve to have option stop pon
[18:48:12] <_methods> s/pon/on
[18:48:43] <dirty_d> where is that?
[18:48:44] <_methods> that way if you don't want to stop you can just turn option stop off

[18:49:30] <_methods> is there an op stop toggle in axis?
[18:49:48] <_methods> in machine menu

[18:53:09] <dirty_d> hmm
[18:53:15] <dirty_d> next problem, lol
[18:53:32] <dirty_d> i need to be able to jog after the M1 to zero the new tool against the workpiece
[18:53:35] <_methods> hehe shoot
[18:53:43] <dirty_d> i dont have an atc or indexable tools
[18:53:51] <_methods> yep
[18:54:10] <_methods> you probably want to set up a tool change position i believe
[18:54:54] <dirty_d> seems to be machine zero by default
[18:54:58] <dirty_d> if i use M6
[18:55:41] <dirty_d> but i wouldnt mind if the program just paused, let me jog and load a new tool, jog to zero, then unpause the program
[18:56:47] <_methods> i think most people with no tool changer have a tool change position set up and it will automatically move to that position when you want to do a tool change
[18:56:57] <_methods> away from your workpiece
[18:57:09] <_methods> and somewhere easy to change the tool then set the height
[18:57:15] <jthornton> dirt just break your program up at tool changes
[18:57:21] <_methods> that too
[18:58:08] <dirty_d> oh i guess i just need to hit stop while its paused, jog, hit run, then hit unpause
[18:59:23] <dirty_d> can you set the tool change position relative to the work zero?
[18:59:50] <_methods> i set mine relative to machine position not work position
[19:00:04] <_methods> my work positions could be all over
[19:00:15] <_methods> i want it to move to teh same spot every time for a toolchange
[19:00:32] <_methods> not some random location relative to a work coordinate
[19:00:36] <dirty_d> the only reason i wouldnt wanna do that is i have no machine zero, because i have no switches
[19:01:09] <_methods> well even without switches if you set your machine zero in a similar spot every time you should be fine
[19:01:13] <dirty_d> true
[19:01:41] <dirty_d> i can just use marker to mark each axis and that would be pretty close
[19:01:49] <_methods> yeah
[19:02:07] <_methods> that's probably the best way if you dont' feel like messing with switches
[19:02:28] <_methods> but if your power goes out you're kinda screwed tryin to pick back up with no switches
[19:02:53] -!- skunkworks_ has quit [Ping timeout: 245 seconds]
[19:03:08] <dirty_d> youd have to rezero against the workpiece anyway wouldnt you?
[19:03:22] <_methods> well if you record your work zero relative to machine zero
[19:03:23] <dirty_d> i wouldnt imagine those switches are accurate to a thou are they?
[19:03:31] <_methods> you can just move back to that point and reset zero
[19:03:49] <_methods> at least it's something kinda repeatable
[19:03:56] <_methods> but i'm not sayin it's 100%
[19:03:59] <_methods> or accurate lol
[19:05:21] <toast-work> why?
[19:05:32] <toast-work> (why would you want a work-relative tool change)
[19:05:39] <dirty_d> damn, lol. it doesnt show the current line when its paused, i was hoping it would so i could put a little comment in there
[19:06:16] <toast-work> generally changer-less machines move the table go to machine Z0, move the table out of the way, then issue a M00

[19:07:35] <malcom2073> My father ran into this, he couldn't get it to set offset while paused, he wound up splitting his program into 4 different programs and manually tool changing re-zeroing inbetween
[19:07:49] -!- anarchos has quit [Quit: This computer has gone to sleep]
[19:07:51] <malcom2073> What's the proper way to do that?
[19:08:33] <_methods> offset while paused?
[19:08:59] <malcom2073> Let me ask, I think he couldn't get it to jog Z while paused, so he couldn't set tool zero
[19:09:08] <_methods> ahh
[19:09:19] <_methods> well it won't move while it's m00 or m01
[19:09:34] <malcom2073> So how do you zero a new tool?
[19:09:38] <_methods> so what i'd do is put a 123 block or something of known height and set all tools to it
[19:09:57] <malcom2073> ah
[19:10:05] <_methods> loosen collet
[19:10:13] <_methods> drop cutter down to height block
[19:10:15] <_methods> tighten collet
[19:10:20] <_methods> slide height out
[19:10:24] <malcom2073> yeah, that makes sense, just set his tool change positio nto a place that works with that
[19:10:29] <_methods> yeah
[19:10:38] <_methods> then all your z's will be the same or similar
[19:10:40] <malcom2073> Great, I'll let him know, he was beating his head against the wall on that heh
[19:10:42] amnesic is now known as amnesic_away
[19:10:51] <_methods> you could have diff known height blocks
[19:10:57] <_methods> and that would determine your z
[19:12:00] <_methods> 123 block with some jo blocks on it for diff heights
[19:12:26] <PetefromTn_> I wish that would work heh
[19:12:43] <malcom2073> I sent him an email suggesting that
[19:12:54] <_methods> what?
[19:13:22] <_methods> for you PetefromTn_ i'd use a height gage and a cat40 holder like andypugh
[19:13:38] <_methods> poor man's presetter
[19:13:40] <PetefromTn_> I do my tool changes and heights in the machine
[19:13:58] <PetefromTn_> and I have a height gauge and granite plate but I never use it for that
[19:14:33] <PetefromTn_> but I am here to tell you that I TRIED to do as you said bring the cutter to a certain point and then change tools in the collet and pull the tool down to the 123 block etc.
[19:14:45] -!- paideia has quit [Quit: Leaving]
[19:14:45] <_methods> not close enough?
[19:14:46] <PetefromTn_> problem is that the collet pulls the tool UP into itself when you tighten
[19:14:49] <_methods> yeah
[19:14:57] <_methods> this is true
[19:15:03] <PetefromTn_> so you would be fiddle farting around an awful lot trying to get it right
[19:15:13] <PetefromTn_> unless .005 is good enough for you I suppose
[19:15:51] <PetefromTn_> honestly from what I saw you would be lucky to get that close
[19:16:20] <PetefromTn_> the only real answer for a machine that does not have repeatable toolholders is electronic touch off of each tool during the program that I can see..
[19:17:21] <skunkworks> you can setup a tool hight sensor. Set the first tool - then measure the rest.
[19:17:35] <PetefromTn_> with linuxCNC not having jog while paused that makes it necessary to have some kinda custom macro to make this happen and I would think some special tool table settings too
[19:17:53] <PetefromTn_> can you do that?
[19:17:58] <skunkworks> yes
[19:18:09] <PetefromTn_> I am not sure how the tool table would be updated for each tool?
[19:18:15] <PetefromTn_> during the program running
[19:18:57] <PetefromTn_> it that is possible at all it would be way better to do that for a CNC router with non consistent tool placement in the collet than anything else
[19:19:07] <PetefromTn_> if
[19:19:11] <skunkworks> right
[19:19:42] <PetefromTn_> on my Cinci I just touch off all tools before the program runs and everything is fine because cat40 is repeatable
[19:20:13] <skunkworks> right - if you have indiviual tools - that works wonderfully
[19:20:18] <PetefromTn_> but with the routers etc that do not have special toolholders or other means of repeatable tool placement an electronic touch pad is the way to go..
[19:20:37] <PetefromTn_> honestly I want BOTH LOL
[19:20:39] <skunkworks> http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=nc_files/tool-length-probe.ngc;h=8b41233d2afe19ef6b9f17706108d0eb356f066b;hb=HEAD
[19:20:52] <PetefromTn_> I am working on a tool probe setup here slowly LOL
[19:21:53] <PetefromTn_> OK nice... glad to know it has been done I figured it must have..
[19:22:24] <toast-work> r8 is also repeatable IF you don't use r8 collets

[19:23:13] <zeeshan-mill> what pin is used to set the speed when you call like a m3 s1000?
[19:23:19] <zeeshan-mill> i need to scale it before i pass it to vfd
[19:23:33] <PetefromTn_> how do you set the G30 position?
[19:23:34] <cradek> zeeshan-mill: motion has a variety of spindle-speed-out type pins
[19:23:45] <skunkworks> in the ini
[19:24:00] <skunkworks> then g30.1 iirc
[19:24:00] <cradek> zeeshan-mill: normally you can just set the dac's scaling
[19:24:09] <zeeshan-mill> oh
[19:24:09] <cradek> g30 position is not in the ini file
[19:24:21] <skunkworks> cradek, for the tool chane position
[19:24:31] <cradek> tool change position IS in the ini file
[19:24:56] <cradek> or you can use g30 for the tool change position by setting an ini option, in which case the position is not in the ini file
[19:24:56] <skunkworks> I communicate very well
[19:25:02] <cradek> it's clear as mud
[19:25:24] <PetefromTn_> so for instance I use the G59.3 position for my tool touchoff position now
[19:25:37] <PetefromTn_> how would you setup the G30 to that position?
[19:25:42] <zeeshan-mill> im using modbus

[19:40:51] <_methods> cool
[19:40:53] <Rab> I didn't think gcodetools took the path width into account.

[19:47:36] <Rab> With gcodetools, make sure to combine continuous path elements with Ctrl-K; you may have to join path nodes manually. Otherwise gcodetools will happily do a tool plunge for each little segment of an apparently continuous path.
[19:47:45] <Crom_> getting flatcam right now as well

[19:50:06] <Crom_> I'm setting Z to go and down a max of 0.050"
[19:53:19] <_methods> yeah use ctrlk like Rab said
[19:55:30] <Rab> Gcodetools does what it says, but it's nothing close to real CAM.
[19:56:25] <_methods> meh looks pretty cool to me for just doing some quick jpg stuff

[20:13:30] <_abc_> I already have that
[20:13:36] <Rab> NCSim working OK in Wine, sorta...renders the gcode, I haven't gotten it to display the running sim yet.
[20:13:53] <_methods> yeah sorry i'm on a winderrs box at work
[20:14:02] <_methods> i guess i could have found something linux in a vm
[20:14:37] <Crom_> well image2gcode is gonna take awhile
[20:15:34] <PetefromTn_> Rab thats a cool little box you made with the gcode tools
[20:15:45] <Rab> PetefromTn_, thanks!
[20:16:30] <Rab> The box itself is a diecast Hammond enclosure, it wasn't tall enough so I made a polycarbonate spacer.
[20:16:35] <PCW> _abc_ latest is LinuxCNC 2.6.5 on Debian Wheezy
[20:16:42] <_abc_> PCW thanks!
[20:18:39] <PetefromTn_> well it looks good
[20:18:57] <PetefromTn_> plastic is fun to machine I think. cuts like butter and looks cool
[20:19:07] <_abc_> PCW: wheezy is non systemd based right?
[20:19:12] <_methods> it won't break a damn chip
[20:19:14] <_methods> stringy mess
[20:19:32] <PetefromTn_> on the lathe yeah
[20:19:37] <_methods> yeah
[20:19:47] <_methods> machining isn't too bad
[20:19:51] <PetefromTn_> I have made tons of feet of plastic delrin string LOL
[20:19:57] <_methods> hehe
[20:20:05] <Rab> PetefromTn_, polycarb is tough. The first prototype of that spacer didn't work out, so I tried to beak it...wasn't happening.
[20:20:07] <_methods> Rab: you put all those paths on diff layers?
[20:20:28] <Rab> _methods, yeah.
[20:20:51] <Rab> I exported each path as its own job. Kinda time-consuming.
[20:21:01] <_methods> well it's free
[20:21:06] <_methods> and it works
[20:21:10] <_methods> mine is making gcode
[20:21:16] <Rab> But both sides of the spacer needed to be milled, and I think there was a tool change too.
[20:21:19] <_methods> that's all i need to know
[20:21:30] <Rab> yah man
[20:22:56] <Rab> Having said that, I'm a little frustrated with all the fiddling around. Going to try PyCAM as soon as the router is running again.
[20:23:09] <PetefromTn_> I know there are free programs like that for 2d toolpathing but every one I looked at was very limited and buggy and annoying. I am not sure the benefit of just free over something like CamBam or even sheeetcam or others...

[20:24:51] <PetefromTn_> awesome!
[20:24:59] <PetefromTn_> what did you wind up doing to fix it?

[20:26:53] <zeeshan-mill> i can't afford to blow money on fixing it this month
[20:26:58] <zeeshan-mill> ill order parts next month
[20:27:05] <PetefromTn_> understand that scenario

[20:27:47] <zeeshan-mill> like a brake
[20:27:58] <PetefromTn_> for what?
[20:28:07] <zeeshan-mill> for some reason i can still spin the back gear

[20:33:39] <PetefromTn_> does the jaws pull down?
[20:33:46] <jdh> making t nuts?

[20:34:23] <zeeshan|2> these are the "precise t-nuts"

[20:36:48] <zeeshan|2> do you remember what it was called?
[20:36:52] <PetefromTn_> I am trying to remember what it wsa used for
[20:37:23] <PetefromTn_> it was about a heavy 1/16" thick or so.
[20:37:31] <zeeshan|2> that will be perfect
[20:37:33] <zeeshan|2> it was flexible too?

[22:38:39] <zeeshan> maybe some sort of ramping in and out
[22:38:43] <zeeshan> while it plunges
[22:38:48] <PetefromTn_> sure
[22:39:04] <jack16> yes, ramping helps
[22:39:06] <PetefromTn_> you don't want to plunge or you will have marks most likely at that spot
[22:39:31] <jack16> HSM-ish slotting will be even easier on endmi

[22:45:24] <PetefromTn_> yeah but they are there late a lot so it is probably no big deal
[22:45:47] <zeeshan> just tell him youre watching the launch
[22:45:47] <PetefromTn_> we did not set a time or anything i just told them I would be heading over here in a bit
[22:45:53] <zeeshan> america used to watch all the launches
[22:45:55] <zeeshan> it was such a big deal
[22:46:01] <zeeshan> i want those days back
[22:46:05] <zeeshan> hopefully mars changes that
[22:46:09] <PetefromTn_> honestly it is a big deal
[22:46:16] <PetefromTn_> at least it is to me
[22:46:20] <zeeshan> me too
[22:46:24] <zeeshan> but not the avg public
[22:46:28] <zeeshan> the apollo missions
[22:46:33] <zeeshan> almost ALL of america was watching
[22:46:45] <zeeshan> shit most of the world was watching
[22:46:46] <PetefromTn_> especially with all the non govermnment entities involved now
[22:46:55] <PetefromTn_> it is very interesting to me
[22:47:27] <PetefromTn_> but of course being from South Florida and having watched the shuttle launches several times in person I kinda have a special place in my heart for it and NASA
[22:47:58] <zeeshan-mill> awww
[22:48:03] <zeeshan-mill> i wish i saw in real life
[22:48:37] <PetefromTn_> yeah it is pretty awesome really
[22:48:51] <PetefromTn_> its a shame it became so commonplace people take it for granted anymore
[22:50:01] <jack16> will they try 1st stage recovery again?
[22:50:09] <PetefromTn_> yeah apparently
[22:50:32] -!- chillly has quit [Quit: Ex-Chat]
[22:50:38] <PetefromTn_> they are gonna try to land the rocket boosters on that drone landing craft in the ocean
[22:50:53] <PetefromTn_> pretty damn ambitious really
[22:52:49] <jack16> well they did "land" it last time.
[22:53:06] <PetefromTn_> I don't think that qualifies
[22:54:22] <jack16> For military it would be considered total success
[22:54:24] <_methods> just the fact that they brought it back down on the pad........epic
[22:54:34] <_methods> from orbit
[22:54:36] <_methods> well
