[00:16:33] <Bushman> stepgen counts says it's back to 0
[00:17:20] <andypugh> It is basically inconceivable that the mumber of pulses LinuxCNC has tried to make, and the counts value will be different.

[00:29:55] <Bushman> i'm so confused right now that i have no idea what is going on with this ;/
[00:30:49] <andypugh> I am puzzled that the little stepper isn't on fire.

[01:10:40] <XXCoder1> I'm pretty far from knowing how do that lol
[01:11:08] <Bushman> do what? give up or write g-code?

[01:12:13] <Bushman> well, it's like telling your machine "go 2mm this way on X axis please" except you just type "G1X2"
[01:12:57] <XXCoder1> yeah was pretty sure it wasn't that hard, just can't visualize yet
[01:13:20] <Bushman> the linux cnc visualises your g-code for you
[01:13:38] <Bushman> just refresh the file and all the edits will show up
[01:14:22] <Bushman> it gets tricky when you want to use your own sub routines that you call like in programming language
[01:14:33] <XXCoder1> cool
[01:14:40] <XXCoder1> just had a random thought
[01:15:01] <Bushman> but untill you tell him simple things like "go there", it's quite straight forward
[01:15:20] <XXCoder1> what if theres special program that dynimically runs cnc, and its programmed to cut based on voice. expensive way to do lps lol
[01:15:51] <XXCoder1> lp is grooves on disc basically after all
[01:16:07] <Bushman> hmm...
[01:16:18] -!- i_tarzan_ has quit [Ping timeout: 265 seconds]
[01:16:20] <Bushman> it's doable with fast machines
[01:16:25] -!- i_tarzan has quit [Ping timeout: 268 seconds]
[01:16:41] <Bushman> fast, rigid and precise :P
[01:16:52] <XXCoder1> indeed

[01:17:58] <andypugh> Lots of ways to control machines. I was using CamBam today, but I couldn't make it do a 3D profile, so I hand-wrote that G-code with point positions from the CAD package (click a node on the shape, convert that to G1 Xn Yn Zn
[01:18:25] <Bushman> put a disc on A axis and run it on constant speed, then set constant speed on X and Z takes the voice data and cuts it onto the disc. it's stupid simple, right!?
[01:18:35] <Bushman> that's why it won't work XD
[01:18:48] <XXCoder1> heh too many chances of miscut or screwups lol
[01:18:57] <XXCoder1> unless you pre-record voice
[01:19:12] <andypugh> I am absolutely sure that you could cut an LP with LinuxCNC.
[01:19:46] <andypugh> It is only a very small modification to my hexagon boring thing.
[01:20:04] <XXCoder1> would think its very automatable. script that reads sound files and figures disc size, spirl pattern so on
[01:20:24] <XXCoder1> done, just input object to be cut into cut speed so on
[01:20:51] <Bushman> XXCoder1: i'm sure some tricky implementation of fake servo feedback would do the trick without actually running any code besides the A spin and X feed
[01:20:52] <andypugh> Basically a conventional lathe facing move, with the "offset" HAL component adding the sound data as a wiggle in the X.
[01:21:26] <XXCoder1> lol would be funny if someone figured how. not too useful for me, was random thought
[01:21:33] <andypugh> It's actually so easy that it isn't interesting enough to actually do :-)

[01:22:32] <Bushman> you know, huge cone, tiny needle
[01:22:43] <andypugh> You could use your CNC as a gramahone.
[01:23:02] <Bushman> hmm...
[01:23:08] <XXCoder1> Bush yeah I'm deaf so even if it works perfectly.. yeah lol
[01:23:14] <andypugh> For extra fun you would use a mill and circular interpolation. (A lathe is too easy) :_)

[01:24:38] <XXCoder1> well other than needle I think
[01:24:44] <XXCoder1> yeah born that way lol
[01:24:52] <Bushman> suck to be you
[01:24:56] <XXCoder1> why?
[01:25:19] <Bushman> cause i can hear and i know how many things you're missing out
[01:25:32] <Bushman> not trying to be mean or anything
[01:25:36] <XXCoder1> meh. lol
[01:25:42] <andypugh> It's possibly one of the easiest things to work around, more so than being blind, less so than having no sense of smell.
[01:25:55] <XXCoder1> andypugh: thats where youre wrong'
[01:26:01] <XXCoder1> I find lack of smell MUCH more annoying
[01:26:13] <XXCoder1> poisoned myself few times
[01:26:25] <andypugh> I have quite a weak sense of smell.
[01:26:33] <Bushman> you mean you don't have smell either?
[01:26:37] <XXCoder1> I dont have any ability to smell
[01:26:37] <andypugh> I reckon touch would be the very worst to lose.
[01:26:54] <Bushman> ok, can you see?
[01:27:17] <XXCoder1> thankfully enough yes lol. 180 degree+ FOV :P
[01:27:26] <Bushman> just making sure before i'll post you some hot babes and get no response
[01:27:37] <Bushman> :P
[01:27:46] <andypugh> Unless IRC interfaces now do direct neural links, I reckon he has to be able to.
[01:28:00] <XXCoder1> theres ways around like text to voice
[01:28:07] <Bushman> andypugh: ugh... braile readers
[01:28:21] <XXCoder1> but yeah having 2.5 senses suck sometimes but most times its fine.
[01:28:48] <Bushman> i am oversensitive to high pitched sounds
[01:28:52] <andypugh> It's not just braille. Without touch you can't pick things up, and you break yourself a lot.

[01:31:02] <andypugh> It's unusual to have no sense of touch, but I think I have heard of it happening. There are people who can't feel pain, which is more common.
[01:31:16] <XXCoder1> yeah no feeling is very rare
[01:31:54] <andypugh> There is a cahracter in "The Girl with the Dragon Tattoo" who can't feel pain.

[01:41:09] <Tom_itx> andypugh it's alwasy fun to find out who you're talking to though
[01:41:17] <NickParker> Hey andypugh do you remember how you got table mode working for the hostmot2 stepgen?
[01:41:34] <NickParker> You gave me an example bit file that made one axis work back in december or so
[01:41:34] * Bushman is gone
[01:42:06] <Tom_itx> NickParker was that your first bit file?
[01:42:30] <NickParker> Tom_itx: The one I generated today? It was the first that didn't effectively brick the pc yeah
[01:42:35] <Tom_itx> i noticed you booted with it today
[01:42:47] <Tom_itx> did you use my tutorial for it?
[01:42:50] <Tom_itx> just curious
[01:42:51] <andypugh> NickParker: I am vague on the details. It is possible that I generated a bitfile for you,
[01:43:39] <Tom_itx> just woke from a 'jt' nap
[01:44:08] <andypugh> I have actually set up an Amazon cloud virtual PC that I wanted to set up to be a bitfile server, but then I got distracted
[01:45:22] <Tom_itx> it would be a cool utility to enter your boards and needs and have a bit file generate
[01:45:59] <andypugh> Yes, that was the plan. But I am not sure I have the time to learn the skillz

[01:46:43] <Tom_itx> i found out on mine with too many functions in the file it caused timing issues
[01:48:16] <Tom_itx> so although it may be automated i'm not sure every file generated would perform correctly
[01:49:39] <pcw_home> If the compile meets timing it should work
[01:50:06] <Tom_itx> you'd need a way to monitor the warnings

[01:54:43] <pcw_home> I do most now with a batch file that builds all the configs
[01:57:05] <NickParker> Well anyway, does anybody remember what pins I need to set up for table mode with 4 outputs in hm2 stepgen?
[01:57:23] <NickParker> is it just 2 pair of step/dir for each axis?
[01:58:40] <NickParker> or, better question, did table mode ever get documented? You added it at the end of last year because I asked andypugh

[02:06:06] <PetefromTn> Ooh nice vague and unclear excellent ....
[02:06:16] <pcw_home> in the pin desc there are separate pins for each table output

[02:08:32] <NickParker> I'll look through all that
[02:08:34] <andypugh> But now I can't see why there are only 4 bytes of pattern, and I can't remember if they are "columns" or "rows".

[02:23:19] <R2e4_> im in the process to understand HAL better.
[02:23:40] <PetefromTn> Is that even possible?
[02:24:05] <R2e4_> the docs are good if you know it allready.
[02:24:25] <R2e4_> not very intuitive to learn from scratch from
[02:25:06] <R2e4_> need a HAL for beginners doc
[02:26:41] <PetefromTn> I spent a few hours trying to setup a part to machine this afternoon and ran up against some broken and dull bits I needed to setup and then tried to use my drill doctor to fix them only to get absurdly frustrated with that infernal piece of shit and finally succumbing to driving down to the Home Despot to buy some rather shitty replacement bits...then it was dinner time LOL.
[02:27:48] <R2e4_> lol, i feel your pain. i need a cylindical grinder for doing just that.
[02:27:51] <andypugh> R2e4_: We have many hal-for-beginners docs. Or do you need more simpler still?
[02:28:11] <R2e4_> where r they?

[02:33:07] <R2e4_> I read that one again completely this morning.
[02:33:12] <PetefromTn> Well from the bits I have bought individually the best ones have been us made...
[02:34:16] <PetefromTn> Especially when compared to the Chinese crappy ones I got in two different drill indexes I have bought over the years.

[02:37:13] <PetefromTn> There is also a Chicago something that is US made they sell but are apparently not as good.
[02:37:42] <Tom_itx> and a fair smaller set
[02:37:51] <Tom_itx> and a box full of assorted ones
[02:38:19] <andypugh> US biased recomendations here:
http://www.practicalmachinist.com/vb/general/recommendations-twist-drill-brands-199628/
[02:38:29] <PetefromTn> That's the kind of set I am needing and have but mine are Chinese crappy ones. I have been slowly replacing the shitty ones with better bits as I get them but many are broken or missing.
[02:39:25] <Tom_itx> i dunno what brand mine are
[02:40:28] <andypugh> I buy these when I want a one-off that I know will work well. But I assume they are a re-brand so not too helpful:
https://www.cromwell.co.uk/publication_page_pdfs/1705/82.pdf
[02:40:28] <Tom_itx> i sometimes get bits for a job that go in the box or with a tap that they go with
[02:40:44] <Tom_itx> i've heard of cromwell
[02:41:25] <XXCoder1> what is bit file?
[02:41:25] <andypugh> Cromwell are a shop, not a manufacturer, though.
[02:41:57] <Tom_itx> a file for manually removing bits from a surface
[02:42:03] <R2e4_> when i engage my brake on the Z while the driver is enabled, i get an OL error on the drive
[02:42:18] <R2e4_> imassume that is normal
[02:42:38] <R2e4_> not good, but would be normal behaviour.
[02:42:42] <XXCoder1> isnt it toolpath that usually does it?
[02:42:49] <Tom_itx> XXCoder1 a bit file is a file that controls the way mesa cards work
[02:42:55] <XXCoder1> oh
[02:43:37] <XXCoder1> usually not a concern unless need custom thing huh?
[02:43:54] <andypugh> Actually, a set of Dormer bits isn't _that_ crazy-priced:

[03:04:52] <PetefromTn> Guess I didn't answer his question too well LOL.
[03:07:41] <XXCoder1> if I buy sbr16 rails and ball screw stuff seperately how do I know if ball screw is long enough?
[03:09:06] <XXCoder1> if too long waste of money, too short useless
[03:09:25] <XXCoder1> but say if rail is 1000mm what should screw be? same or maybe bit longer?
[03:09:35] <andypugh> Well, the trick would be to buy the right length
[03:09:49] <XXCoder1> thats what I said yes lol but shorter
[03:10:17] <andypugh> Do you have any design drawings?
[03:10:33] <andypugh> or a 3D model, for preference?
[03:10:35] <XXCoder1> nah but I would just do basic moving gantry type
[03:10:57] <XXCoder1> so "table" box with rails on sides thats lower than surface
[03:11:13] <andypugh> The screws can be shorter or longer than the rails. It depends on design.
[03:11:20] <XXCoder1> screw under the "table" moving gantry
[03:11:40] <XXCoder1> thats why I suspect it should be slightly longer
[03:11:48] <XXCoder1> so it reaches end of box and are supported
[03:11:49] <andypugh> The travel will be less than the rail length by the bearing length.
[03:12:37] <XXCoder1> just found sbr12. smaller but probably too weak?
[03:12:51] <andypugh> if you are going for wide-spaced bearings for stiffness then the guides could be twice as long as the machine travel.
[03:13:24] <XXCoder1> found kit of 6x 500mm sbr12. small enough lol
[03:13:29] <XXCoder1> $200
[03:14:22] <XXCoder1> just over 1.5' too small lol
[03:14:28] -!- mpmckenna8 has quit [Quit: Leaving.]
[03:14:32] <andypugh> The screw will be as long as the machine travel, plus the thust bearing length, plus the drive coupling length. But then if you put the nut on the far side of the gantry (or on both sides) you add the gantry too.
[03:15:20] <andypugh> You _really_ need a drawing. Or a model. Some sort of design, at least.
[03:15:28] <XXCoder1> indeed
[03:15:42] -!- PetefromTn has quit [Quit: Bye]
[03:15:57] <XXCoder1> would sbr12 be strong enough to be stable on light alum routing?
[03:16:06] <andypugh> And a "design" is not a sketch saying "it looks a bit like a fish". You need dimensions and part numbers that you intend to use.
[03:16:36] <XXCoder1> still doing research on parts so yeah still on "kinda like fish" stage lol

[03:19:33] <Tom_itx> could be a challenge
[03:19:59] <XXCoder1> indeed
[03:20:01] <andypugh> Well, first buy a lathe. Nobody needs a milling machine more than they need a lathe.
[03:20:04] <XXCoder1> I need some challenge
[03:20:27] <XXCoder1> andy I'm looking for cnc router
[03:20:34] <XXCoder1> is cnc milling same thing?
[03:21:00] <CaptHindsight> a recent trend is to discuss a mill/router/cheese slicer with no drawings, 3d models or specs and argue over t-slot, 16mm vs 20mm rails and ballscrew sizes
[03:21:04] <andypugh> What do you want to rout?
[03:21:19] <XXCoder1> any wood and slow cut on alum
[03:21:58] <andypugh> OK, maybe woodworkers might need a router more than a lathe.
[03:22:04] <CaptHindsight> evidently if there is a youtube showing to toy working without any measurements of lash, flex, play or wobble that proof that it works well
[03:22:12] -!- ries has quit [Quit: ries]
[03:23:24] <andypugh> I spent all of today cutting 16mm thick profiles with a 3mm cutter because I bought stock too small to use a decent-sized cutter.
[03:23:29] <andypugh> That was annoying.
[03:24:17] <andypugh> Because my mill has a max spindle speed of 1500 rpm, 3mm cutters are _really_ slow,
[03:24:37] <Tom_itx> i bet that took a while

[03:26:16] <XXCoder1> yea lol prefers cast iron if I recall
[03:26:23] <CaptHindsight> people tend to be more teachable when they are trying to finish their machine vs at the beginning
[03:27:37] <andypugh> Indeed. I have started to tell folk to buy a 2020 engraver kit first, make that work, then, and only then, take their production machine offline to retrofit.
[03:28:26] <andypugh> 2020 is great for the controller enclosure, but not for a machine frame.
[03:28:48] <XXCoder1> I hope my job sutation would change soon so I can afford more
[03:28:57] <CaptHindsight> all the recent Chinese routers I've purchased are all machined pretty well, but they seem to be clueless as to how to mount the ballscrews
[03:29:46] <andypugh> Very few people understand bearings
[03:29:47] <CaptHindsight> I uncrated one today where the X axis had >1/8" of play
[03:29:59] <XXCoder1> 1/8? wow holy gap
[03:30:32] <XXCoder1> when its usually far less than mm from what I recall on tolences
[03:30:50] <CaptHindsight> they used split lock washers as springs for preload on the bearings
[03:31:05] <Tom_itx> heh
[03:31:11] <andypugh> I actually find bearing arrangments fascinating, it's my favourite design feature. I like nothing more than a zig-zag load path through multiple bearings.
[03:31:23] <XXCoder1> guess thats bad thing, dunno lol
[03:31:54] <CaptHindsight> another relied on the flex coupling for preload
[03:32:18] <andypugh> XXCoder1: Screw backlash should be too small to measure, ie bearings pre-loaded to more than cutting force.
[03:32:30] <CaptHindsight> I could compress the coupling as well as get some axial play out of the stepper motor
[03:32:48] <XXCoder1> wish I knew which size SBR equals how strong so on. for example sbrXX is strong enoggh for wood cutting but not alum so on and on
[03:33:32] <CaptHindsight> yeah, any more than maybe 5-10 lbs of cutting force and you have .125" lash

[03:36:28] <CaptHindsight> lots of suppliers have application notes, hardly anyone seems to read them
[03:36:42] <andypugh> This is similar to what I used on my X. This is rotating-nut. I wanted the drive to reduce X travel as little as possible. So the belt and the bearing are in the same plane. In the final design (not online at the moment) I flipped the motor and used two bearings with preload.

[03:38:06] <andypugh> The point I am trying to make, though is that this is not something you can design in your head. You need a drawing, if you are really clever, or a 3D model if you are less clever
[03:38:26] <humble_sea_bass> you also need to get it wrong
[03:40:14] <andypugh> This is the final iteration of that design in the metal:

[03:49:59] <humble_sea_bass> you see, the reason I say stay off the CNC Zone forums is that you ask 10 dudes there for design advice and you'll get 10 different answers based on their level of experience, location on the autism spectrum, brand prefence etc

[04:11:36] <andypugh> zeeshan: Ah, yes, Q-max cutter and abused mill. I had a lot to do.
[04:11:41] <humble_sea_bass> all weak as hell and disappointing
[04:12:27] <CaptHindsight> you're supposed to buy it in those little 250ml cans
[04:12:35] <XXCoder1> finally starting to form some design ideas
[04:13:02] <humble_sea_bass> only time I was happy to see a starbucks in my life was in Kyoto with a hangover
[04:13:21] <XXCoder1> :) I dont care personally, I'm not coffee person
[04:13:27] <XXCoder1> hell I dont even drink soda
[04:13:33] <zeeshan> maybe you guys can help me identify something i found in the toolbox
[04:13:35] <zeeshan> 1sec.
[04:13:45] <GuShH_> zeeshan: drilldo

[04:14:55] <tjtr33> anyone know an example of a python script accessing mesa pins?
[04:14:56] <tjtr33> this is in regards to ...rodfrey asked" Can I access arbitrary pins and signals from a remap python script? "
[04:15:13] <humble_sea_bass> boss coffee! I remember his weak flavor like it was yesterday
[04:15:26] <CaptHindsight> oh it's near Bletchley park
[04:15:32] <andypugh> Yes :-)
[04:16:03] <andypugh> Which is an excellent several days-out
[04:16:24] <XXCoder1> looks like zees hagving bit issues finding pic or object itself
[04:16:33] <zeeshan> i was playing with the drilldo.
[04:16:37] <zeeshan> got preoccupied
[04:16:46] <XXCoder1> lol
[04:17:09] <CaptHindsight> andypugh: I'm not sure how many of the uhmerikans would make the trip
[04:17:17] <zeeshan> http://i.imgur.com/rqvNFgV.jpg
[04:17:19] <zeeshan> what is it
[04:17:23] <zeeshan> 3 matching pairs
[04:17:26] <zeeshan> or weird looking blocks
[04:17:35] <GuShH_> failed project?
[04:17:36] <zeeshan> i guess i shouldnt say pairs
[04:17:43] <andypugh> tjtr33: Well, once your code makes pins in HAL they can link to anything, including Mesa
[04:17:59] <zeeshan> tell me!
[04:18:09] <GuShH_> zeeshan: unfinished space invaders
[04:18:11] <XXCoder1> wonder what those numbers mean, dont seem to mean size
[04:18:15] <tjtr33> but the pins are already made, so i'm missing some word thing here
[04:18:26] <zeeshan> looks like an aluminum castle

[04:19:05] <zeeshan> i will use them as billet blocks to make something else out of
[04:19:23] <andypugh> Perhaps they fit into slots in a machine table, as a fixture?
[04:19:44] <zeeshan> hm

[04:20:34] <andypugh> Yeah, I was about to ask about that,
[04:20:49] <zeeshan> i lost it a while ago
[04:20:51] <XXCoder1> in least pic was useful
[04:20:54] <zeeshan> ive been cleaning up the garage
[04:20:58] <andypugh> Looks like a PSA one

[04:25:52] <GuShH_> I don't care, I want the vise!

[05:05:46] <CaptHindsight> $200 used
[05:06:40] <tjtr33> uses a pad between work and vacuum table, so you cut into the pad, and not into the table when cutting 'thru' parts.
[05:07:09] <CaptHindsight> you're not trying hard enough :)
[05:07:35] <tjtr33> looks like ceramic, but at 200$ its something else
[05:08:13] <tjtr33> we used to make vacuum plates out of graphite, but we were machining graphite and had loads of it
[05:08:16] <CaptHindsight> tempted to get it, I get lots from D&S in Minn
[05:10:03] <tjtr33> did you see the t-slotted welding tables at bottom of that page?
[05:10:52] <CaptHindsight> which page?
[05:11:08] <tjtr33> scroll up to your last url posted
[05:11:27] <tjtr33> Orbotech-Vacuum-Table
[05:11:38] <CaptHindsight> ebay must add that dynamically, I just get tool holders

[15:09:25] <R2E4> mornin
[15:10:42] <R2E4> I have a theoretical question.
[15:12:01] <R2E4> IF you have two relays with one enrgizing the second relay, would there be a detectable delay from whenthe first one energizes and the second one?

[15:12:59] <archivist> relays take time, ms
[15:13:03] <pcw_home> sure maybe 20 ms or so for small relays
[15:13:29] <pcw_home> reed relays are the fastest I think
[15:14:15] <R2E4> plus the time a solenoid energizes, could be enough time the axis moves before brake is applied.
[15:14:48] <skunkworks> I would not thing inches though...
[15:15:46] <R2E4> I'm debating wether I should run the power to the brake solenoid through the servo drive ready contacts or use a relay.
[15:16:21] <R2E4> I dont have the contact rating of the ready signal contacts though.
[15:16:58] <pcw_home> I would be careful with the brake wiring since there's so much energy stored in the brake coil
[15:17:50] <pcw_home> even with a suppresor its going to be all kinds of nasty when you engage the brake
[15:18:09] <pcw_home> (disconnect the 90VDC)
[15:19:48] <R2E4> Thats why I was asking for the time it takes for the relay to energize. I have the 90v going through a big relay that is being energized with 24vdc. I can run the drive ready contacts in series with the 24v enrgizing the brake relay.
[15:20:28] <R2E4> But that would innduce a delay(time it takes for the relay to energize).
[15:21:25] <pcw_home> I cant imagine that 20 or so ms makes that much difference
[15:21:50] <pcw_home> how long does it take the brake to engage?
[15:22:51] <R2E4> Less than a second
[15:24:41] <pcw_home> if its more than 1/10 of a second, worrying about relay delays is probably not useful
[15:25:17] <pcw_home> since the main delay for applying the brake is in the brake itself
[15:25:23] <R2E4> I think I have two choices. 1. In HAL inject a delay when I turn machine off to give the brake time to engage. 2. interrupt the ENA from 7i77 and inject a delay to give brake time to engage.
[15:26:55] <R2E4> Can I assume there is no built in delay parameter in the 7i77 firmware?
[15:26:59] <pcw_home> It still seem wrong the the brake has any noticeable delay to engage
[15:27:59] <pcw_home> 7i77 outputs are actuated ~ 50 usec after the command
[15:28:22] <PetefromTn_> sorry guys Mornin JT and R2E4 and everyone...
[15:29:33] <R2E4> IS that coinfigurable per axis? Have to ask, but I think I know the answer.
[15:31:34] <pcw_home> the delay (thats just the communication delay/processing time not anything you can change)
[15:31:37] -!- skorasaurus has quit [Ping timeout: 240 seconds]
[15:31:48] <R2E4> I've never seen this machine run with the old control but I think I am safe to say it didn't do what its doing now. Like you said either the solenoid is bad or the old control handled the delay because one of the contact that engaged the brake was from the old control.
[15:33:07] <R2E4> So if you would have hit emergency stop or shut of the control the old control could have induced the delay giving the brake time to engage then disable the drive.
[15:33:55] <pcw_home> So I guess you could provide some overlap by disabling the drives a bit later but this is not very safe
[15:34:47] <pcw_home> (you want to disable immediately on a ferror but perhaps with a delay at shutdown)

[15:36:02] <pcw_home> do you have the motor specifications? it may list the brake engage/disengage times
[15:36:15] <R2E4> yeah, let me look
[15:36:28] <XXCoder1> if motor does have this delay, womder if upgradable
[15:39:43] <R2E4> IT doesnt give engage/disengage times.Just says it is a Spring engaged, electromagnetic type and frictiuon torque.
[15:40:37] <R2E4> exciting voltage 90vdc +-10% at .3A
[15:43:30] <PetefromTn_> Setting up here finally to machine the part I screwed up last time LOL... Snapped a 3/8 carbide endmill like a twiggy!!
[15:44:17] <pcw_home> how heavy is the Z axis?
[15:44:43] <pcw_home> Just wondering how fast it accelerates in free fall
[15:45:05] <ChuangTzu> wait
[15:45:16] <ChuangTzu> the mass of the z axis doesn't affect it's free fall speed
[15:45:19] <ChuangTzu> :S
[15:45:24] <skroon> hey all
[15:45:28] <ChuangTzu> hey skroon
[15:45:49] <skroon> anyone of you use cambam?
[15:45:51] <pcw_home> It does
[15:46:28] <pcw_home> because the large part of the inertia is in the ballscrew/motor
[15:47:00] <R2E4> I'll video it.
[15:47:32] <ChuangTzu> i guess i wouldn't consider that a free fall then, but i see what you're saying
[15:48:02] <pcw_home> Halscope Z position would be better
[15:48:40] <pcw_home> By free fall I meant with servo/brake disengaged
[15:50:23] <PetefromTn_> I am still considering that CHNC lathe I found locally but I gotta sell my Manual 12x36 lathe to get it and I am not sure I can live without a lathe until I can get the new one working if at all...Sucks to be poor LOL

[16:31:56] <XXCoder1> why would someone slow down brake?
[16:32:25] <R2E4> The snubber is in the control panel across the wires leaving the control panel headed to the motor. IF they did, it might be in the motor.

[16:43:07] <R2E4> it is .1uf and 200ohms snubbers their using

[17:01:11] <zeeshan> :P
[17:01:46] <TekniQue> ladder is only visual when the whole design fits on one page
[17:02:07] <TekniQue> beyond that there's no way of visualising what the fuck that fucking shit is doing
[17:02:56] <zeeshan> going through someone elses code isnt any different ;p

[17:13:06] <kengu> rodfrey: i have had those appear when i try to run axis faster than settings allow

[17:14:10] <kengu> joint follow error is another one of those
[17:15:12] <skunkworks> rodfrey: if nothing is attached to the limit switch inputs - you may get noise - triggering the error
[17:16:15] <rodfrey> ok... maybe noise is triggering the limit switches that's possible
[17:16:24] <archivist> are the limits pulled up or down, do you need to invert the state
[17:16:35] <rodfrey> for speed, I don't think so... it's the spindle and I'm starting real slow
[17:17:00] <rodfrey> All the motion is working fine (it's trivial kinematics)... it's just getting the spindle going that's giving me problems
[17:17:07] <rodfrey> without the spindle I can home, run programs, etc.

[17:20:39] <archivist> use lower value pullups on limit switches
[17:20:45] <rodfrey> Yeah, I'm leaning toward noise too
[17:21:43] <rodfrey> the limit switches are active low... bad practice I know but I didn't know how to make the inductive switches I had go active high. I should look into that I guess.
[17:22:15] <rodfrey> no resistors on the limit switches...they feed right into the 7i76. Is that a big error right there?
[17:22:35] <Einar> The original wiring in my Boxford had screened cables between VFD and motor. But the screen was not grounded! What were they thinking!?
[17:23:26] <zeeshan> i use armor cable for the wire between the vfd and motor
[17:23:32] <zeeshan> seems contain all the noise ;p
[17:23:54] <rodfrey> OK, it's definitely noise - thanks guys! I had spindle-on pin linked to the enable line for the VFD - I removed that and put 24v directly onto enable.
[17:24:10] <rodfrey> When I do, the inductive switch LEDs all start to flicker.
[17:24:12] <Einar> If you connect the screen to ground, yes. Otherwise the screen does not do any good.
[17:24:50] <zeeshan> well the armor cable grounds through the clamp type connector that secures the wire againt the enclosure

[17:53:05] <pcw_home> rodfrey: the 7I76 inputs are active high so if you have NPN (pulldown) type proxes you need a stiff pullup fo each one

[18:24:25] <archivist> sensible price too
[18:24:49] <archivist> test in the shop as its near you
[18:25:10] <zeeshan> i'd have to drag a surface plate and feeler gauges

[18:31:15] <PetefromTn_> Man I suck at figuring champfer tool depth and offset...
[18:32:25] -!- afiber__ has quit [Quit: Konversation terminated!]
[18:32:47] <zeeshan> why
[18:32:55] <PetefromTn_> IF I wanna use my 45 degree cutter and have the diameter of the cut match my 1/4 inch endmill I profiled the part with I need to go down .125 deep and then offset the width of the face of the champfer cut I want right?
[18:34:03] <PetefromTn_> THis is assuming I use a zero tool width for the tool in my cam program..
[18:34:22] <zeeshan> too much going on in one sentence
[18:34:22] <zeeshan> ;p
[18:34:59] <PetefromTn_> So I offset the depth to match the width of radius of the cut plus the extra .030 I want the face of the champfer to be I guess.
[18:35:33] <zeeshan> what size chamfer are you putting on the edge
[18:35:36] <sabotender> moo
[18:35:41] <zeeshan> .1x.1?
[18:35:49] <zeeshan> or .125x.125
[18:36:29] <PetefromTn_> I was thinking now actually I want like a .050 wide champfer face on the part.
[18:36:45] <zeeshan> so you gotta plug 0.050 deep
[18:36:50] <zeeshan> + tool radius
[18:36:53] <zeeshan> offset

[18:37:27] <R2E4> I would think it depends on andle the bit. Using a V-bit for the chamfer?
[18:37:33] <PetefromTn_> oh so you figure the depth not the width...
[18:37:39] <zeeshan> he said 45 degree tool
[18:37:41] <zeeshan> http://blog.supertoolinc.com/wp-content/uploads/2013/05/chamfer-cutter.jpg
[18:37:43] <zeeshan> youre using that right?
[18:37:47] <PetefromTn_> I know some people do one or the other.
[18:38:06] <zeeshan> well its easier just to plunge straight down
[18:38:10] <PetefromTn_> yeah 45 degree tool not like that but similar enough
[18:38:14] <zeeshan> cause im assuming you know your tool height
[18:38:52] <PetefromTn_> Tool is setup from tip in TLO and I program it for depth in the cam...
[18:39:14] <Tom_itx> maybe set it up for half it's diameter
[18:39:24] <PetefromTn_> but I have been figuring the toolpath offset to get the champfer I want probably easier to use the depth.
[18:40:05] <zeeshan> the cam programmers hated me for specifying 30 degree chamfers

[18:40:20] <zeeshan> cause its easier to program for a 45 degree =D
[18:40:23] <PetefromTn_> So if I want the tool to touch the edge barely I go .125 deep and .125 offset and that is the edge. Then if I want a champfer of .050 I just go that much deeper?
[18:40:36] <Tom_itx> i would think so
[18:41:05] <Tom_itx> but the tip is probably not a full point
[18:41:11] <zeeshan> pete
[18:41:20] <PetefromTn_> no it is not but it is close enough..
[18:41:27] <tjtr33> IchGuckLive, I bought the HeeksCNC 1.0, and installed on win8.1, works fine (had some early problems ). I will be looking thru all your videos, thx!
[18:41:42] <zeeshan> if your tool looks like mine then its a bit more complex
[18:41:45] <zeeshan> but if you got a tool like
[18:41:45] <Tom_itx> so the chamfer will be deeper than you expect
[18:42:00] <PetefromTn_> yeah but only very slightly...

[18:42:24] <PetefromTn_> there is no callout here to meet I am making this part custom for me so If it goes a touch deeper so be it...
[18:42:27] <zeeshan> all you just need to line up the center line of your tool
[18:42:34] <IchGuckLive> tjtr33: your welcom e
[18:42:40] <zeeshan> offset by 0.050 away from the part
[18:42:47] <zeeshan> and plung down 0.050
[18:42:54] <Tom_itx> you don't wanna chamfer with the tip
[18:43:05] <zeeshan> yes thats why you offset 0.050 away from part
[18:43:05] <Tom_itx> the surface speed will be off
[18:43:06] <tjtr33> people should know it also has solid cut simulation
[18:43:07] <PetefromTn_> actually no that won't cut anything..
[18:43:15] <Tom_itx> use the center of the cut
[18:43:24] <zeeshan> air cut it
[18:43:24] <Tom_itx> better surface speed there
[18:43:25] <zeeshan> :D
[18:44:05] <PetefromTn_> you need to offset .050, then plunge .050 and that will be the edge then you plunge another .050 to get the champfer you want right?
[18:44:09] <Tom_itx> and you could calculate it as if it were a .125 cutter
[18:44:36] <CaptHindsight> HeeksCNC 1.0 is Winders only. Is he dropping the Linux version?
[18:44:48] <PetefromTn_> I want to make the champfer match the profile I used with a .25 inch diameter cutter so the diameter of the cutter where the cut happens needs to be .250..
[18:45:14] <CaptHindsight> IchGuckLive: any idea if he's dropping Linux?
[18:45:17] <PetefromTn_> which means I need to offset .125 and plunge .125 plus whatever champfer depth I need.
[18:45:43] <XXCoder1> could anyone make heekscnc work? it crashes randomly here
[18:46:09] <tjtr33> CaptHindsight, theres no 1.0 on linux so far, and yes windows sucks.
[18:46:39] <Tom_itx> pete your cutter will match the profile no matter where it's set if it's offset the right amount
[18:46:44] <tjtr33> XXCoder1, worked fin for me thru the frech pump tutorial, and for Ich's pocketing tutor. gcode ran fine
[18:46:51] <XXCoder1> odd
[18:47:22] <XXCoder1> I added block then circle, it usually crashes by then. I was trying to make smiley face toolpath
[18:47:22] <tjtr33> XXCoder1, did the fre version run ok for you, did you have the machining& help menus?
[18:47:39] <XXCoder1> I use free version
[18:47:56] <zeeshan> pete you can make the offset .175" too
[18:48:01] <zeeshan> and plunge .125
[18:48:08] <zeeshan> and you'll still get the .125 chamfer you're after
[18:48:18] <zeeshan> cause its a 45 degree tool
[18:48:28] <CaptHindsight> tjtr33: any idea how well these work?
http://www.alibaba.com/product-detail/DK7750BZ-cnc-wire-edm-controller-with_989106414.html?s=p
[18:48:33] <PetefromTn_> yeah I know but I kinda like using the depth because I think the guys in the shop do it that way and I need to get used to doing it that way.
[18:48:35] <zeeshan> as long as your tool is wide enough
[18:48:53] <zeeshan> PetefromTn_: yea but say your tool is worn out in that spot
[18:49:00] <tjtr33> XXCoder1, ok i dunno why he says try the free first, but apparently it wont run on all systems, and he wants to keep those people from going nuts
[18:49:02] <zeeshan> you could just offset it a bit more and use a fresh cutting edge
[18:49:11] <zeeshan> so i don't think its a standard thing
[18:49:31] <CaptHindsight> tjtr33: here's another
http://www.alibaba.com/product-detail/CNC-wire-cutting-EDM-DK77-series_571789768.html
[18:50:15] <tjtr33> CaptHindsight, lemme find the controller/generator set ( and no i havent used one, what you show is lilley a reciprocating wedm using moly wire and crazy fast windlass )

[18:51:11] <tjtr33> CaptHindsight,
http://dgctek.en.made-in-china.com/product/veBEDZFUGOkV/China-EDM-System-CNC-EDM-control-system-.html
[18:51:16] <PetefromTn_> yeah actually tool wear is the reason I want to get used to doing it that way because you can adjust your offsets at the control without having to redo the cam if you program the depth...
[18:51:23] <tjtr33> ^^ a full kit, just add machine tool
[18:52:10] <zeeshan> oh i see what you mean
[18:52:14] <tjtr33> CaptHindsight, but if you want a refurb lo cost wedm, lemmeno
[18:52:15] <PetefromTn_> They have a couple wire EDM machines at the shop where I am temporarily working
[18:52:15] <zeeshan> then you can just manually offset in the control
[18:52:32] <zeeshan> controller
[18:52:41] <PetefromTn_> and the big one automatically feeds the wire AND drills thru holes for you LOL..
[18:52:47] <PetefromTn_> zeeshan Yea exactly...
[18:53:12] <zeeshan> just program it to have a safe offset like 0.125
[18:53:18] <zeeshan> so you're not cutting at the nose of the chamfer tool :D
[18:53:50] <PetefromTn_> yup that is what I am trying to do here plus .125 offset makes the cutter diameter match the cutter I profiled with...
[18:53:53] <zeeshan> if it was me, i'd figure out where the center of the cutter is
[18:53:59] <zeeshan> and i'd offset it to that amount
[18:54:14] <zeeshan> that way you could at the controller + or - an offset amount to adjust the tool contact point
[18:54:27] <CaptHindsight> tjtr33: what is the price range for those?

[19:16:52] <zeeshan> this mount sound dumb
[19:17:01] <zeeshan> i wanted to ask first before trying to pull it out

[19:19:28] <Tom_itx> i warned about the tip depth
[19:19:52] <Tom_itx> not coming to a point...
[19:20:30] <archivist> zeeshan, home made jigs,fixtures/clamps are a normal extra in old tool boxes, you will make some sometime too
[19:20:38] <PetefromTn_> yeah I don't think that is the problem here I think I messed up on the computations as simple as they are LOL.. I went .175 deep and .125 offset and got a .75 champfer.. No biggie but I would like to know what went wrong so I can get it right next time..
[19:20:39] <zeeshan> archivist: yes
[19:20:55] <zeeshan> its kind of nice to know what they are used for
[19:21:00] <zeeshan> cause they could be quiet useful
[19:21:20] <zeeshan> he gave me a set of machinist clamps that he had to make for his 'final project' when he was back in school
[19:21:26] <zeeshan> they are very nicely made
[19:21:51] <zeeshan> i still havent seen an application where you use machinist clamps though :)
[19:22:03] <archivist> I use them often
[19:22:21] <zeeshan> for what? turning a tap? :D

[19:32:53] <zeeshan> this was like 8 years ago too
[19:33:00] <archivist> that is general purpose maths
[19:33:06] <PetefromTn_> Damn just got another call on the lathe... I want that CNC lathe but I am just unsure of going without a manual lathe for awhile...SUCKAGE
[19:33:18] <Tom_itx> i did drafting with paper and pencil
[19:33:32] <zeeshan> haha
[19:33:34] <zeeshan> what the hell
[19:33:46] <zeeshan> you can apparently find "sin x" for ancles between 5.7 to 90 degrees
[19:33:48] <zeeshan> interesting.
[19:33:57] <archivist> slide rules were expensive when I was a kid
[19:34:05] <zeeshan> how much?
[19:34:08] <Tom_itx> i wish i could find mine...
[19:34:31] <Tom_itx> priceless

[19:35:14] <Nick001-shop> PetefromTn_ You mean you didn't grab that beautifully rusty CHNC?
[19:35:55] <PetefromTn_> LOL I am THINKING about it...
[19:36:11] <PetefromTn_> would you get it if it was able to be had for around a grand?
[19:36:45] <archivist> I think I need manual lathes as well as cnc
[19:37:09] <archivist> one off is a lot easier and faster manual
[19:37:40] <Nick001-shop> depends on how deep the rust is on the Z slide - will it clean up without pits to score the wear plate under the Z axis
[19:37:44] <zeeshan> jog the cnc
[19:37:44] <PetefromTn_> http://imagebin.org/301223

[19:39:13] <PetefromTn_> It really did not look all that bad in the photos I thought. He says it is nothing but light surface rust but I would have to go look at it..
[19:39:35] <XXCoder1> yeah rust could be like cancer
[19:39:46] <XXCoder1> have to be careful see if its just on surface or deeper
[19:39:53] <archivist> light rust makes a good oil holding surface :)
[19:40:10] <XXCoder1> in cars rust can be literal cancer, evenually destroying car if not taken care of

[19:50:39] <Nick001-shop> the surface is hardened & ground steel and will pit if rusted.
[19:50:40] <Nick001-shop> All depends on what kind of work your doing - this machine is for lighter work although I've gone to 6" parts
[19:51:16] <sabotender> moo.
[19:51:21] <PetefromTn_> I doubt I have ever done anything much larger than 6" on my current lathe so that would be fine I think...
[19:51:27] <sabotender> wait, what is dirt cheap again?
[19:51:41] <zeeshan> http://tricities.craigslist.org/tls/4341313026.html
[19:51:44] <PetefromTn_> I really want to have an ACCURATE lathe for making parts here...
[19:51:50] <sabotender> I have never used a lathe before :-P
[19:52:05] <zeeshan> i've turned a 12" pierce on my lathe before
[19:52:07] <zeeshan> but it wasnt solid
[19:52:11] <zeeshan> it was a really thick tube
[19:52:25] <zeeshan> housing for friends turbine
[19:52:43] <PetefromTn_> mine will do 12 over the ways and 14 over the gap bed if necessary but honestly you gotta take crazy light cuts at that diameter....
[19:52:49] <archivist> accuracy on a lathe is in the hands of the user :)
[19:52:57] <zeeshan> archivist: tell me about it
[19:53:06] <PetefromTn_> not if it is a CNC lathe...
[19:53:07] <zeeshan> the other day i was grooving for my rotary valve
[19:53:25] <zeeshan> and did a couple of test cuts and measured and they were 0.002" off from what i was telling the machine
[19:53:28] <zeeshan> guess what it ended up being?
[19:53:38] <zeeshan> the grooving tool was stuck out too much by 1.5"
[19:53:42] <archivist> cnc does not make a silk purse out of a pigs ear
[19:53:43] <zeeshan> and was flexing
[19:53:54] <PetefromTn_> exactly right...
[19:54:03] <PetefromTn_> that was my point.
[19:54:04] <sabotender> archivist: why is that?
[19:54:16] <zeeshan> sabotender
[19:54:20] <zeeshan> cause you need to consider tool geometry
[19:54:23] <zeeshan> and work holding techniques
[19:54:30] <zeeshan> if they flex, cnc isn't going to fix that for yuou.
[19:54:35] <archivist> bad mechanics, machine design etc
[19:54:48] <zeeshan> unless you have some sort of live meaasuring device
[19:54:48] <sabotender> a lathe spins an object in a circle and has a cutting blade that makes it the same all around right?
[19:54:53] <zeeshan> like those marposs gauges
[19:54:59] <PetefromTn_> I have owned this manual for over a decade and made TONS and TONS of parts on it for myself and for customers so I will miss it when it goes but I really want a nice CNC lathe to run here.
[19:55:05] <archivist> but a hardinge is one solid lump
[19:55:06] <sabotender> its jused to make those interestingly shaped table legs
[19:55:17] <sabotender> -j
[19:55:45] <zeeshan> with those older hardinges
[19:55:54] <zeeshan> you gotta do some manintenance work before they run right
[19:56:02] <zeeshan> like from mrpete's videos
[19:56:12] <zeeshan> his tailstock was misalgined
[19:56:21] <Nick001-shop> you still need a manual lathe for certain work - like 1 pc of general work or making tooling -
[19:56:24] <sabotender> not sure what a tailstock is, but go on...
[19:56:35] <zeeshan> Nick001-shop: you can do all that stuff on cnc
[19:56:42] <PetefromTn_> I had one awhile back and did not have to do jack to it. It was a tight and smooth machine but it was just not a CNC lathe and was never going to be one...so I sold it.

[19:56:51] -!- amnesic has quit [Client Quit]
[19:57:00] <sabotender> how is tooling made with a lathe and why is a lathe so useful for making it?
[19:57:03] <archivist> you dont get feel with cnc
[19:57:05] <zeeshan> the main thing you lose is the 'feel' of turning the wheels
[19:57:13] <zeeshan> which honestly isnt that big off a deal because
[19:57:16] <zeeshan> you'll see it visually and hear it
[19:57:18] <zeeshan> if something is wrong
[19:57:29] <Nick001-shop> alot of times it's faster and easier on a manual lathe
[19:57:33] <zeeshan> i agree
[19:57:36] <sabotender> i can see how a hand router is useful, because it can cut on a template, but never understood the manual lathe
[19:57:50] <zeeshan> but if you're on a limited budget, i'd just use a cnc machine with pendant
[19:57:50] <PetefromTn_> Well I have been turning wheels for years on manual lathes so I am good with losing them to CNC now hehe
[19:57:53] <zeeshan> over a manual mill anyday!
[19:58:01] <zeeshan> cause its got way more capabilities at the cost of some time
[19:58:08] <sabotender> turning wheels?
[19:58:22] <PetefromTn_> handles...
[19:58:31] <zeeshan> PetefromTn_: even with manual i rarely turn by hand
[19:58:34] <zeeshan> i always use power feed

[20:59:32] <NickParker> Hey people probably already know this, but I remember there was some confusion about it back in December.. The results of mesaflash --scanpci when you have a 6i25 in depends on the loaded firmware. it will identify as 5i25 regardless of jumper positions if it has 5i25 firmware on it.
[20:59:58] <NickParker> With firmware that uses work.sixi25_x9card.all it will identify as 6i25

[21:29:59] <sabotender> well. I wonder if I can use a cnc router to make carpentry wonders such as drawers and chests
[21:30:09] <XXCoder1> I bet yeah
[21:30:52] <XXCoder1> hell you can do in such way that theres details that would take long while in old way
[21:31:44] <sabotender> oh I don't need or want details in what I am planning
[21:32:25] <XXCoder1> lol ok
[21:33:27] <sabotender> I am going to sell my tablet computer to help fund my cnc router purchase
[21:34:08] <sabotender> I do not really need or want it anyway
[21:34:13] <PetefromTn_> sure you can... you can machine dovetails with a CNC router too....it is just a different way of doing it...

[21:34:52] <XXCoder1> indeed
[21:35:07] <XXCoder1> hell you can do designs that would hell for regular wood shop

[21:35:59] <XXCoder1> One of plans I have once I have CNC is to do lots fun with inlay designs.
[21:36:27] <XXCoder1> different wood, stains so on. Bet it wouyld be awesome.
[21:37:00] <XXCoder1> I think simple idea too, do inside cut on large peice, do outside cut on inpay part
[21:37:01] <XXCoder1> inlay
[21:38:12] <PetefromTn_> I need to build a nice CNC router I know you heard me squalking about the Mechmate but that thing just looks so good.
[21:38:15] <XXCoder1> this'd be great addon.

[21:46:56] <XXCoder1> probably VERY flammable too lol
[21:47:00] <PetefromTn_> actually you can make both box joints or dovetails with CNC routers it has been done before...
[21:47:06] <sabotender> oh prolly so
[21:47:16] <XXCoder1> probably needs 5axis? because dove inward slope
[21:47:20] <PetefromTn_> You will be needing a rather large CNC router to make drawers tho...
[21:47:27] <XXCoder1> or use bit thats like that hmm
[21:47:40] <sabotender> PetefromTn_: not for small drawers with pre-cut planks
[21:47:40] <PetefromTn_> no you can machine angles with 3d toolpaths or angled cutters..

[21:51:58] <XXCoder1> I'm building plans now, I'm making it open to any best rail set I can find pretty cheaply
[21:52:50] <sabotender> PetefromTn_: can't afford a larger one
[21:53:04] <sabotender> im getting a smaller-well built one
[21:53:37] <sabotender> i dont mind doing a bit of hand-work anyway
[21:54:14] <PetefromTn_> the difference in price between a small one and larger one is not all that much especially if you build it yourself...

[22:09:57] <XXCoder1> pete thats what I plan too.
[22:10:04] <XXCoder1> how thick should mdf bed be though?
[22:11:52] <XXCoder1> inch? 12 inches? lol
[22:12:28] <PetefromTn_> XXCoder1 Dunno man I would get on the forums and read up on them lots of different designs for them and some are nicer than others. Probably 3/4 or 1" I would say but that depends a lot on the design. Loetmichel on here makes some nice ones from some kinda resin board that is much stronger than MDF but for a hobby router there are tons of MDF routers out ther.
[22:12:51] <XXCoder1> I am considering using cheap steel or alum L beans for gantry though
[22:13:29] <XXCoder1> it does need to rigidly hold 2 SBR 16 beams with sway or something

[22:21:51] <Connor> Hard to explain.. But.. the Carriage can only go down to the bottom edge of gantry.. In never can go below it.. You have to use long bit's or a extended bracket to get your router lower..
[22:22:04] <sabotender> Connor:
http://www.youtube.com/watch?v=TYAfNTvgTak theres also links to accuracy tests on the panther
[22:22:14] <XXCoder> this clamp system is cool, but wouldn't it also cause router bit to impact it if edge cuts is needed?

[22:39:15] <sabotender> hiya andypugh
[22:39:19] <XXCoder> yeah but then my design will not be based on that I would think.
[22:39:36] <XXCoder> I suspect mine will be wood base with metal L beams gantry
[22:39:36] <PetefromTn_> what are your travels?
[22:39:40] <XXCoder> using SBR16
[22:39:58] <XXCoder> that depends on best deal I can find on SBR thats also free shipping
[22:40:27] <XXCoder> 1000 mm or bit over 3 ft seems most common so likely will be my X length
[22:42:22] <PetefromTn_> yeah then that design probably won't work for you.
[22:42:31] <XXCoder> yeah
[22:42:40] <XXCoder> mine wont be too complex I dont think
[22:42:48] <PetefromTn_> The whole side of the base is like 22.2644 inches.
[22:43:28] <PetefromTn_> Would make for a sweet little table top machine tho. Cuts aluminum too pretty decent apparently.
[22:43:41] <XXCoder> good thing my design does NOT depend on size of rails. its very easily expandable. well till 8 feet long because thats bigger than standard 4' 8' board
[22:43:59] <PetefromTn_> what is your design?
[22:44:37] <XXCoder> roughly like this
http://www.wired.com/design/wp-content/uploads/2012/10/blueChick_3.jpg

[22:55:45] <andypugh> I suppose this weekend wasn't a total waste, I did learn a lot about CAM, even if I was hoping to make parts. :-)
[22:55:59] <PetefromTn_> whaddya mean?
[22:56:15] <XXCoder> Two frames, one having very thick MDF or plywood as support for it as well as mount points for Z rails
[22:56:36] <NickParker> andypugh: If you had to hazard a guess, do you think I'll need to up the NumRegs value for the stepgen moduleID to implement table mode?
[22:56:54] <XXCoder> andy what cam was you trying to learn on?
[22:56:57] <NickParker> It seems like it would take more registers, but I don't know if the "StepGenNumRegs" variable will handle that for me.
[22:57:22] <andypugh> NickParker: Table mode does work, but possibly not with the number of outputs you need.
[22:57:50] <andypugh> I think NumRegs is about the counter registers etc.
[22:58:03] <andypugh> XXCoder: I am using CamBAM.
[22:58:28] <XXCoder> sahh yea been playing with that a bit. it has good cheap/good blance I think
[22:58:39] <NickParker> andypugh: Well I'll just try to make it blink LEDs in an appropriate way and hope for the best then. And ignore the ModuleID stuff for now, since all the table stuff is rolled into the standard stepgentag
[22:59:30] <andypugh> I initially did a an X-scan of the 3D shape, and added some profiles. Then I decided to convert outlines to pockets, so started again. Then eventually I realised that "waterline" does almost exactly what I did by hand with the pockets
[23:00:44] <andypugh> Though a weakness of all the CAM packages have tried so far is that "waterline" doesn't choose sensible waterline heights for mechanical components.
[23:01:01] <XXCoder> waterline?
[23:01:21] <andypugh> It's one of the CAM methods.
[23:01:23] <Tom_itx> level
[23:01:27] <PetefromTn_> http://imagebin.org/301223 I made that with CamBam today LOL..
[23:01:37] <XXCoder> niced
[23:01:44] <Tom_itx> andypugh what have you been working on?
[23:02:05] <XXCoder> that smiley face tjing is only thing I made so far. still no idea if it made sense and would be routed properly lol
[23:02:10] <andypugh> Frame stiffeners for a Ner-a-Car
[23:02:17] <Tom_itx> ahh i remember...
[23:02:18] <PetefromTn_> Waterline is a 3d toolpath strategy that kinda works around the part like a line of water draing down into the pocket.
[23:02:19] <R2E4> PetefromTn_: What size is that chanfer? .2?
[23:02:32] <XXCoder> hmm ok
[23:02:35] <Tom_itx> andypugh did you get code done for them?
[23:02:44] <PetefromTn_> R2E4 TOO DAMN DEEP LOL..
[23:02:53] <XXCoder> anyway I got files if you guys are curious lol
[23:03:10] <PetefromTn_> It was supposed to be .050 but when I screwed the pooch on the setup it turned out to be .075
[23:03:25] <andypugh> I would have made more progress except that all of friday night was spent cutting out shapes from 16mm plate with a 3mm bit. This is because the plate was only just big enough. A 6mm bit would have been a lot more approriate.
[23:03:29] -!- tmcw has quit [Remote host closed the connection]
[23:03:53] <PetefromTn_> andypugh How do you find the 3d toolpaths in CamBam so far? Any good
[23:04:12] <andypugh> It seems pretty good if you choose the right options.
[23:04:49] <PetefromTn_> I have not done any 3d toolpaths yet in it and I am anxious to try it but have not found anything I need to machine 3d just yet.
[23:05:02] <andypugh> I have learned that if you want a flat surface at a given height then the trick is to set a specific finish height for the waterline op.
[23:05:17] <PetefromTn_> what do you mean does not choose sensible heights for mechanical components?
[23:05:23] <andypugh> Then add further waterlines starting there down to the next flat face.
[23:05:54] <Tom_itx> are you talking about the bolt boss's?
[23:06:32] <PetefromTn_> you mean a specific finish depth like the final depth setting in typical MOP's?
[23:06:39] <andypugh> Wel, say I have a 16mm blank and a flat surface at 3.3mm, and do a 3mm waterline, then I get waterlines at 13,10,7,4 mm. so my thinckess ends up at 4 not 3.3
[23:06:55] <tjtr33> NickParker, what kind of stepper are you trying to drive? i have some 8 pole ( 9 wire ) steppers, and am looking at the table mode OR extending stepgen.

[23:07:17] <Tom_itx> ahh, it doesn't calculate for the final depth
[23:07:22] <NickParker> er, that's obviously not right
[23:07:35] <NickParker> 4 pole, only driving current through each pole in one direction
[23:08:05] <andypugh> Tom_itx: Well, it does caclulate for the _final_ depth. That's my point. But not for intermediate flat planes.
[23:08:13] <PetefromTn_> Have not tried it can you set the final depth for that?
[23:08:47] <andypugh> So, if you have an intermediate flat plane you need to set a final depth to suit, then add a second, third etc waterline op to touch the other surfaces.
[23:08:49] <tjtr33> NickParker, thx... oh, i would have thought that was built in, but maybe just 2 pole 3 pole and 5 pole
[23:09:08] <PetefromTn_> are you using bounding boxes to set that up?
[23:09:17] <XXCoder> found this, great guide I think.
http://www.cnccookbook.com/CC3DCAMToolpaths.html
[23:09:25] <NickParker> tjtr33: there's a stepgen mode in software stepgen which does just what i want
[23:09:32] <andypugh> PetefromTn_: I am using bounding boxes too, but that's different
[23:09:32] <NickParker> but not in hm2 stepgen, outside table mode of course
[23:10:03] <tjtr33> yeh, i think mine would need more table entries
[23:10:26] <andypugh> I am using a boundary shape so that that it only machines the cavity and not the outside profile, because that would eat the jig.

[23:11:18] <Tom_itx> andypugh, how'd you work out the open end?
[23:11:47] <andypugh> The bounding box and/or editing the polyline profile
[23:12:34] <PetefromTn_> Got pics?
[23:23:08] <PetefromTn_> Jeez man I gotta get the pocket machined for this part so I can do the second side.

[23:34:10] <andypugh> The original drawing is here:
http://www.geutskens.eu/neracar/100-frame_assembly.htm I am making parts 103 and 104. Which taper in all directions, and have a kink.

[23:36:51] <Tom_itx> frame stiffeners
[23:39:38] <Tom_itx> i bet the originals weren't aluminum either :)
[23:39:57] <andypugh> Oh, they were. That is why they no longer exist.
[23:40:07] <Tom_itx> really?
[23:40:14] <andypugh> Except as piles of white powder.
[23:40:34] <NickParker> in the PinDesc array, what is unit?
[23:40:55] <NickParker> the 'x"00"
[23:41:04] <Loetmichel> andypugh: i've seen that on a tank on the coast of france
[23:41:09] <Loetmichel> right on the beach
[23:41:26] <Loetmichel> the rusty steel motor block was there
[23:41:39] <Loetmichel> ... the aluminium head was completely missing
[23:41:46] <NickParker> oh nvm it appears to be the stepgen number for my application
[23:42:16] <Loetmichel> strange sight, seeing the bolts still in place and the valve cam shaft and the valves fallen into the cylinders ;-)
[23:42:29] <ebrummer> I'm prepping to convert a 3 axis bandit controlled cnc mill to LinuxCNC. the resolvers feedback into the westamp servo amps. upon conversion do I split the signal to the computer and the servo amps or just one of them?
[23:42:48] <andypugh> NickParker: Looking at regmap.txt, it looks like you can have 16 steps and whilst the default width is 6 bits, more is possible.
[23:43:24] <NickParker> andypugh: Cool, so my NumRegs should be fine.
[23:43:31] <NickParker> I only need 8 steps width 4
[23:43:34] <andypugh> It looks like you could have 32 wire steppers
[23:43:49] <andypugh> Surely you need width 8?
[23:44:12] <NickParker> andypugh: Why would I need 8?
[23:44:20] <andypugh> You have 8 wires to drive?
[23:44:28] <PetefromTn_> http://imagebin.org/301245 http://imagebin.org/301246 finally got it out of the machine now for the pocket milling so I can do the second side.
[23:44:29] <NickParker> No, I have 4 per motor
[23:44:52] <andypugh> Oh. Who has the 9-wire 8-phase motors then?
[23:45:03] <NickParker> tjtr33
[23:45:07] <NickParker> i think
[23:45:20] <andypugh> Right.
[23:45:56] <andypugh> In that case, why are you even looking at the bitfiles? You can just use table-mode as it currently exists.
[23:46:33] <andypugh> (Apart from needing a bitfile that actually allocates the other output pins)
[23:47:14] <NickParker> andypugh: That's all I'm doing, allocating pins.
[23:47:19] -!- amiri has quit [Ping timeout: 264 seconds]
[23:47:41] <andypugh> I had forgotten that the general bitfiles only allocate 2 pins per stepgen.
[23:47:49] <tjtr33> andypugh, i havent studied it enough yet, these 8pol Responsyn may need more table entries. again i have not studied enough to comment.
[23:48:02] <andypugh> All you need to do is allocate the other stepgen tags to physical pins.
[23:48:15] <NickParker> Hmm, I take it stepgenTable1Pin is replaced with DirPin and stegenTable0Pin is StepPin?
[23:48:36] <andypugh> tjtr33: Let me turn off the mill and have a look.
[23:49:01] <tjtr33> thx andypugh but dont stop what you're doing
[23:49:40] <tjtr33> monday i'll watch the stoc AGie drivers ( 8 leds) to see the pattern, and can scope it
[23:49:50] <tjtr33> and even get prints :)
[23:50:56] <tjtr33> i dug around and see that Mitsubishi wedm's also used them ( 80's vintage)
