[00:01:49] <PetefromTn_> jeez you have an instructor? Nice I had to figure this stuff all out on my own ;)
[00:02:09] <Wolf_> instructor = youtube
[00:02:12] <Wolf_> :D
[00:02:23] <PetefromTn_> aah okay I had the same instructor!
[00:03:05] <MacGalempsy> PetefromTn_: this is the 10 week programming course at the local tech college
[00:03:15] <Wolf_> my cam stuff has option for dwell so must be common
[00:03:28] <MacGalempsy> we havent even used CAM yet...
[00:03:41] <MacGalempsy> we just keep getting hammered on manual programming
[00:03:43] <Tom_itx> dwell is for those moments you just need a rest
[00:03:56] <Tom_itx> MacGalempsy, good
[00:04:02] <Tom_itx> by the time you get to cam you won't need it
[00:04:52] -!- rob_h has quit [Ping timeout: 250 seconds]
[00:06:16] <MacGalempsy> going from drawings to code, is a pretty straight forward process. however, we arent getting any machine time, except to do some basics like setting g54, etc/...
[00:06:21] <Wolf_> knowing what the code does helps :)
[00:06:54] <MacGalempsy> :) one of the guys in the class works with an industrial laser, and he says the CAM outputs still have problems
[00:06:58] <Tom_itx> they don't want you to break their machines
[00:07:08] <MacGalempsy> hehe. for sure
[00:07:20] <MacGalempsy> it is a HAAS VF1
[00:07:32] <MacGalempsy> pretty cool machine
[00:08:02] <PetefromTn_> I like the HAAS machines
[00:08:18] -!- Timbo [Timbo!~tma@cpc5-sgyl28-2-0-cust125.sgyl.cable.virginm.net] has joined #linuxcnc
[00:08:39] <MacGalempsy> if I would have taken the class before getting my machine and retrofitting it, I would have gone for a HAAS
[00:09:27] <PetefromTn_> what machine do you have?
[00:09:43] <MacGalempsy> Light Machine Corp BenchmanXT
[00:09:54] <PetefromTn_> oh thats right
[00:10:23] <MacGalempsy> still working on getting it finished up.
[00:11:09] <MacGalempsy> is there a simple way to have Linux CNC throw an alarm? say for low air pressure?
[00:11:18] <PetefromTn_> honestly while I really like the HAAS machines for me it is a non starter.
[00:11:19] <MacGalempsy> i guess generic alarm
[00:11:28] <PetefromTn_> I could not have possibly affored a HAAS machine new
[00:11:46] <MacGalempsy> who can? but for about $15k used, that seems doable
[00:11:53] <PetefromTn_> and now that I have my Cinci making parts daily and I have relatively little money in it
[00:12:04] <PetefromTn_> I would absolutely do the same thing again
[00:12:34] <PetefromTn_> my machine has a low pressure alarm setup
[00:12:46] <MacGalempsy> https://www.youtube.com/watch?v=SBeUX06Dvpw
[00:12:48] <Wolf_> I’m hoping to get a nice real VMC or something
[00:12:49] <MacGalempsy> HAAS tour
[00:12:49] <PetefromTn_> right now it is set to ONLY turn on a little on screen LED
[00:13:12] <PetefromTn_> but it could easily be routed in to cause an estop condition or something
[00:13:13] <MacGalempsy> is your Cinci running LCNC?
[00:13:17] <PetefromTn_> yeah
[00:13:30] <MacGalempsy> how do you have the pin for the low air set?
[00:13:46] <PetefromTn_> I don't remember the details offhand
[00:14:00] <PetefromTn_> but the machine has a regulator on the back
[00:14:08] <PetefromTn_> that reg has a low pressure sensor on it
[00:14:21] <PetefromTn_> the sensor is wired to an input on the 7i77 card
[00:14:23] <MacGalempsy> thats what I got, a low pressure sensor
[00:14:37] <MacGalempsy> same, just wondering about the coding side
[00:17:08] <PetefromTn_> well I would have to get into it to figure out how we did it has been awhile
[00:17:17] <PetefromTn_> my pal connor helped me ;)
[00:17:26] -!- goutnet has quit [Ping timeout: 240 seconds]
[00:17:33] <PetefromTn_> I do know he just setup a GladeVCP panel with the little LED
[00:17:47] <PetefromTn_> and ultimately it will be part of the structure for the toolchange setup
[00:17:55] <MacGalempsy> so you just use an LED and not an alarm?
[00:18:13] <PetefromTn_> as it is now because my toolchanger is not operational yet
[00:18:21] <MacGalempsy> yeah, I got a buddy looking into the ATC programming right now
[00:18:38] <PetefromTn_> once it is operational the low pressure sensor will be crucial to safe functionality
[00:18:55] <MacGalempsy> if it works out, I can point you in his direction. He is unemployed and pretty good at PLC programming
[00:19:42] <PetefromTn_> well as it stands we have two different toolchange options. Andypugh has apparently built a setup and my pal Connor already has a working test setup as well.
[00:20:07] <PetefromTn_> I just need to figure out how to get my machine to safely and repeatedly orient the spindle before I can test either one.
[00:20:26] <MacGalempsy> no index on the encoder?
[00:20:30] <Wolf_> I want to do a ATC on the x2 at some point
[00:20:41] <PetefromTn_> no it has an index
[00:21:04] <MacGalempsy> my machine has a hall sensor in the shaft that goes true when oriented
[00:21:22] <PetefromTn_> my spindle is a 10HP 12kRPM motor driving a 2-1 belt drive to the spindle and the encoder is on the motor.
[00:22:12] <MacGalempsy> maybe a magnet on the pully?
[00:22:18] <PetefromTn_> I am also currently setup running the spindle via modbus which we have found is inadequate to orient quickly enough
[00:22:38] <PetefromTn_> no like I said the encoder has an index
[00:22:44] <PetefromTn_> My machine already rigid taps
[00:23:33] <MacGalempsy> wow. 14000 HAAS machines sold last year
[00:23:45] <PetefromTn_> the original machine used an completely electronic spindle orient and the new drive does not work the same way so I have to first get the analog control of the spindle reinstalled and then test one of several methods to orient electronically
[00:23:54] <PetefromTn_> I don't doubt it
[00:24:00] <PetefromTn_> every shop around here has them
[00:24:12] <PetefromTn_> the first shop I worked in had like 30 of them
[00:24:25] <MacGalempsy> did you watch that video? there is a quick scene of an ATC with atleast 100 tools

[01:27:50] <PetefromTn_> Being an american I would wear one
[01:28:42] <PetefromTn_> wth is that a TV show I guess? I don't even have cable anymore so I am not familiar with it
[01:28:54] <MacGalempsy> << about to order one. I guess the part I like most about the series is that is about American Made products.
[01:29:23] <MacGalempsy> The American dream, even an ex-con can be successful
[01:30:09] <PetefromTn_> oh is the owner an ex con or something?
[01:30:56] <MacGalempsy> Yeah, in some of the videos he talks about his struggle and coming out of incarceration, finding The Lord.
[01:31:20] <PetefromTn_> nice to hear someone come back from that.
[01:31:46] <MacGalempsy> so while it all seems goofy to the non-yanks, it does hit close to home
[01:31:55] <MacGalempsy> (not personally an ex-con)
[01:32:16] <PetefromTn_> I once got busted for failure to pay a speeding ticket ;)
[01:32:27] <PetefromTn_> I was like 17
[01:32:29] <MacGalempsy> hahaha, warrant style?
[01:32:36] <PetefromTn_> yeah bench warrant
[01:32:54] <MacGalempsy> ahh, i've had a couple of those, but always managed to pay them off before getting busted
[01:33:01] <PetefromTn_> I was sitting on the beach making out with my old girlfriend in my jeep and a police car came up behind me and ran my tags...
[01:33:11] <MacGalempsy> ahhhh.. dang
[01:33:18] <PetefromTn_> yeah it SUCKED
[01:33:28] <PetefromTn_> my girlfriend was pretty cool about it tho....
[01:33:31] <MacGalempsy> at least your exgf could drive your car home
[01:33:39] <PetefromTn_> at least she was when she heard what the charges were LOL
[01:33:52] <MacGalempsy> yeah. for sure

[01:36:58] <PetefromTn_> honestly I was embarassed that I got the ticket in the first place and did not know how to tell my parents

[05:34:35] <Contract_Pilot> Tracking is showing up as a letter?
[05:34:57] <Praesmeodymium> well I bought 5 from the same 76oz/in description you got the 396? oz/in motors from
[05:35:34] <Praesmeodymium> I havent even gotten tracking yet just a message they took my oney
[05:35:37] <Contract_Pilot> they shipped my replacement 48V PSU Priority mail.
[05:36:48] <Contract_Pilot> Log in to new egg account order history should be under order number if they took the money
[05:37:09] <Contract_Pilot> should show shipped and you should have a tracking number.
[05:37:45] <Contract_Pilot> on the Scratched up driver and motor with damage they offering refund as they are out of stock.
[05:37:51] <Praesmeodymium> oh yep shenzhn china
[05:38:12] <Contract_Pilot> Yea, no telling what we will get.
[05:38:56] <Contract_Pilot> China track best info

[05:40:49] <Contract_Pilot> SHENZHEN EMS, CHINA so they may go EMS wich is not to slow.
[05:42:01] <Contract_Pilot> Unless customs want to charge for Duty then we are screwed/
[05:42:31] <Praesmeodymium> under 200$ I think
[05:43:41] <Praesmeodymium> the got my laser cutter through customs somehow, said they were shipping from kentucky or something I think they meant the chinese equivalent

[05:46:13] <Contract_Pilot> I need to e-mail them and request weight.
[05:46:36] <Contract_Pilot> The weight will let us know.
[05:47:52] <Praesmeodymium> I should reall sell mine anyway or I am gonne keep trying to build an aluminum cutting something for under 400$
[05:50:46] <Contract_Pilot> for the weight should be about 4.3 lbs ea for the larger ones 2.1 for the smalled ones

[13:46:22] <archivist> use one and rotate, adjust spindle for min deflection
[13:47:54] <ssi> jthornton: :D
[13:48:23] <ssi> jthornton: once you get a handle on what go is good for and what it's not good for (UI sadly), it's a really awesome language
[13:48:55] <ssi> jthornton: and you're still doing everything sequentially... if you can parallelize it, I bet you can make it REALLY fast
[13:49:20] <archivist> use assembler, even faster :)
[13:49:29] * archivist ducks
[13:51:04] <jthornton> you would have to give me an example of that so I can understand
[13:53:41] <ssi> ok so I'm lookng over your code
[13:54:15] <ssi> looks like getEnt takes a list of lines in the source dxf and tries to find entities within, sticks them in a list and eventually returns the list
[13:54:50] <ssi> then findEndPoints takes that list of entities and tries to derive the endpoints and save them within the struct
[13:55:36] <ssi> so this may not be the most helpful example in the world because of the way you're doing it, but let me see if I can explain
[13:55:48] <ssi> I see two places right off the bat where you can parallelize at least some
[13:56:55] <ssi> one is when you're reading in the lines of the dxf... instead of just appending to your lines slice, you could stick the text on a channel
[13:56:57] <jthornton> a bit newer code
http://pastebin.com/g7LZghPB
[13:57:15] <ssi> that way rather than waiting til you've built teh entire lines array, you can start extracting entities immediately while the file is still being read
[13:57:35] <ssi> then, getEnt would be running in its own goroutine (which is a lightweight thread), and it could be iterating over the channel instead of an input slice
[13:57:48] <ssi> and whenever it finds a complete entity, instead of appending it to an output slice, stick it on another channel
[13:58:14] <ssi> then findEndpoints would read from that channel, and do the endpoint fixup for each incoming entity, and then stick it on yet another outbound channel
[13:58:30] <ssi> then whatever downstream logic you use to arrange the entity would use that channel as its source
[13:58:43] <jthornton> ok, I'll have to study up on channels
[13:58:46] <ssi> that's a little cumbersome at the moment because you are relying on having a complete set of entities before you sort, but you get the idea
[13:58:52] <archivist> a tape sort on the channels
[13:58:59] <jthornton> yea I think so
[13:59:17] <ssi> it's not a big deal to do it sequentially with small dxfs, but when you start getting 10MB files with millions of entities, you can really get a lot of gain by using threads and channels
[13:59:27] <ssi> and that's one of go's biggest strengths, it makes concurrent programming like that super easy
[14:00:09] <ssi> archivist: yea mergesort or something would work well for that
[14:00:19] <jthornton> gotta get over this mole hill first I think then move on to concurrent programming
[14:00:24] <ssi> jthornton: yeah absolutely
[14:00:30] <ssi> just giving you some ideas of where to go in the future :)
[14:00:36] <jthornton> I'm stoked to get this far so quick
[14:00:51] <jthornton> and I've noted them
[14:01:22] <ssi> also, in places where you're using range to iterate over the entities
[14:01:37] <ssi> range actually returns a pair, the index and the item
[14:01:47] <ssi> so you can say for i, ent := range entities
[14:01:54] <ssi> and then you can use ent directly in teh loop instead of entities[i]
[14:01:59] <ssi> a bit cleaner that way
[14:02:04] <jthornton> ah cool
[14:02:11] <ssi> if you don't use the index inside the loop, you can ignore it like this:
[14:02:17] <ssi> for _, ent := range entities {
[14:02:17] <jthornton> _
[14:02:50] <ssi> and I noticed in your first paste that you were doing your error check "backwards" from how most people do it, but it's gone now
[14:03:04] <ssi> it's just a style thing, but usually you'd do if err != nil { handle }
[14:03:12] <ssi> rather than if err == nil { huge block of happy path }
[14:03:20] <jthornton> yea, it looked clunky to test after the fact instead of in the function
[14:05:45] <ssi> I'm glad you're liking it though
[14:05:55] <ssi> I use it A LOT these days
[14:06:07] <ssi> it's good for low level code that hits hardware too
[14:06:22] <ssi> all that podponics stuff I built runs go code that I wrote
[14:06:48] <ssi> it's a bunch of i2c sensors and relays on a beaglebone black cape, and there's a go client that runs on the bbb, phones home for scheduled jobs, and runs all the hardware and reports back metrics
[14:06:52] <ssi> it's great for that sort of stuff

[17:59:36] <enleth> Any ideas on removal and installation of bport spindle bearings without an arbor press?
[18:00:20] <archivist> removal destructively?
[18:00:59] <enleth> Actually I may need to replace both the spindle and the bearings, which means that I just don't have to remove the old bearings from the old spindle in a gentle way
[18:01:13] <enleth> But I may have to put new bearings on a new spindle properly.
[18:01:23] -!- jerryitt has quit [Quit: Connection closed for inactivity]
[18:01:48] <archivist> I tend to make tooling or use a dremel to cut a slot, then chisel to crack it
[18:01:57] <enleth> One stupid idea I have is to use the quill/head as the stop and the knee as the press.
[18:02:57] <enleth> Like, put a board with a hole at the tip of the quill, pass the splined spindle part through it, put the spindle nose on the table with another piece of board under it and crank the knee up gently
[18:03:24] <archivist> see if someone local has bearing pullers (proper ones not toy automotive)
[18:03:54] <enleth> That's for removal, but I think something press-like is needed for assembly?
[18:04:10] <archivist> use a threaded bar through and two machined disks to insert new
[18:04:55] <enleth> Through the spindle? No can do if I get another solid one
[18:05:36] <archivist> spindle not hollow?
[18:05:47] <archivist> tube spacers too
[18:05:55] <enleth> Most QC30 spindles are solid
[18:06:41] <enleth> There are hollow QC30 spindles out there but I don't think they're factory drilled
[18:07:45] <enleth> AFAIK Bridgeport never made a non-QC ISO30 taper spindle for the CNC models, and never made a hollow QC30 spindle

[18:15:21] <lair82> Good afternoon guys, question about grounding, with all the different voltage power supplies used on these controls, should you connect all of common wires to ground, or no?
[18:15:43] <Tom_itx> star ground
[18:15:50] <Tom_itx> yes
[18:16:08] <Tom_itx> just make sure one is not a floating ground
[18:16:08] <archivist> enleth, also you can use threaded rod outside, part of my ex army kit has rods for outer work then an inner push
[18:16:08] <enleth> lair82: there should be a single point where all ground wires meet
[18:16:28] <Tom_itx> aka star ground
[18:17:14] <enleth> Tom_itx: ah, it makes sense, never heard it called that way
[18:17:45] <enleth> archivist: you mean a hollow threaded tube or something?
[18:17:49] -!- Demiurge has quit [Read error: Connection reset by peer]
[18:17:51] <lair82> Ok, I was wondering, there is ac voltage floating around on the 24vdc side of the machine, and I noticed that from the start
[18:18:10] <Tom_itx> single ended shielded wires too
[18:18:32] <Tom_itx> keep data wires away from power wires
[18:18:44] <lair82> What do you mean floating ground?
[18:19:00] <Tom_itx> some devices have a 'ground' but it's not at zero potential
[18:19:05] <enleth> lair82: get one of those nice brass bus bars with wire holes and screws to clap down the wires, connect everything there, connect it to supply ground/PE
[18:19:10] <Tom_itx> rather floating above 0 at some voltage
[18:19:13] <enleth> *clamp
[18:19:21] <Tom_itx> it is ground to the device but not the outside world
[18:19:44] <Tom_itx> my spindle motor controller is one such example
[18:19:57] <Tom_itx> i had to get an isolation board to use it with external logic
[18:21:28] <lair82> Ok, that makes sense.
[18:26:38] <CaptHindsight> how hard do you laugh when a supplier comes back with a comment like "we like to sell it" 4 tons, 5 drums, a truckload at a time, etc., when you ask for pricing on more than you really need anyway?

[19:29:38] <MrSunshine> ah spindle ive ground before
[19:29:47] <MrSunshine> was 0.1mm off int he ER collet cone
[19:30:03] <MrSunshine> this is getting it straight with the world (fix the Z up down motion and tramming it to the table)
[19:30:42] <_abc__> How do you measure orthogonality anyway?
[19:31:30] <MrSunshine> is that up down ?
[19:31:45] <MrSunshine> a square on table and move spindle up and down ? =)
[19:31:56] <_abc__> Right angles to xy planes. The angles...
[19:32:31] -!- tocka has quit []
[19:34:20] <_abc__> More like mounting a smooth cylinder in the collet and then using a precision cube with at least 2 calibrated Z positions for a feeler gauge to feel the cylinder in the collet, and account for runout...
[19:34:42] <_abc__> I think....
[19:35:11] <_abc__> There may be a fancyer tool for that, I don't know.
[19:36:18] <Sync> what?
[19:36:24] <Sync> that is way too complicated
[19:36:38] <_abc__> You are looking for 0.01mm error on a 50mm side cube, that's 1 part in 5000, not something you eyeball.
[19:37:29] <Sync> easily measureable with an indicator
[19:37:50] <_abc__> Right.
[19:38:13] <_abc__> Feeler gauge means dial gauge with feeler.
[19:38:15] <MrSunshine> to see if the Z axis linear bearings moves straight with the world you need to have something on the X/Y table to see ...so a precision square and an indicator i feel would be alot better than a square and a feeler guage :P
[19:38:19] -!- skunksleep has quit [Ping timeout: 240 seconds]
[19:39:17] <Sync> yeah for alinging the Z axis you just indicate along a square

[19:39:39] <Sync> for squareness of the spindle you put the indicator on an arm and turn the spindle 180°
[19:39:44] <Sync> and it has to read the same
[19:39:46] <_abc__> The square needs to be mounted to the table and it has to have calibrated positions, at least 2, for the feeler dial mount.
[19:39:54] <Sync> no
[19:40:31] <_abc__> This is not about spindle runout this is about Z axis orthogonality with table.
[19:40:40] <Sync> yes
[19:40:45] <Sync> you just put a square on the table
[19:40:50] <Sync> and indicate along it
[19:40:50] <MrSunshine> yes, a square on the table, a dial indicator on the moving part of the Z ...
[19:40:53] <Sync> it is pretty easy
[19:40:54] <MrSunshine> move the Z up and down
[19:40:59] <MrSunshine> see if the dial moves

[19:47:50] <_abc__> You need 3 points to define an angle, not 2
[19:47:56] <XXCoder> what kind of problems can spindle runout cause
[19:49:20] <_abc__> Vibration, broken tools, broken material when it is a thin edge, loss of precision, early bearing death.
[19:49:48] <SpeedEvil> World war III
[19:50:06] <_abc__> On a cnc runout should be at most half a resolution step.
[19:50:25] <SpeedEvil> resolution is not the same as accuracy
[19:50:31] <_abc__> Sometimes that is hard so compromises are made.
[19:50:53] <_abc__> Exactly speed.
[19:51:12] <MrSunshine> _abc__: well .. if you have something that ALREADY is square, to measure against ...
[19:51:13] <_abc__> So half an 'accuracy' step is okay too
[19:51:17] <MrSunshine> =)
[19:52:02] <_abc__> You need THREE points. Dial feeler moved to 2 stations on Z.
[19:52:22] <MrSunshine> well you have to explain wtf a dial feeler is then .. to start with
[19:52:26] <MrSunshine> never heard the word even
[19:52:48] <Sync> _abc__: you are not interested in an angle
[19:52:55] <_abc__> Dial gauge with a lever like feeler end.
[19:52:58] <Sync> you shim the axis until it reads the same
[19:53:27] <XXCoder> ok
[19:53:27] <Sync> also that will give you an angle just fine
[19:53:37] <Sync> as you know Z and x/y

[19:57:48] <enleth> Sync: we're talking $300 precision bearings, are ovens healthy for those?
[19:58:07] <MrSunshine> heh we might have talked past eachother then :P, put a square on the table .. measure X until its straight with the square, then measure Y .. if its off then its off :P
[19:58:21] <Sync> yes enleth
[19:59:31] <enleth> What temperature would I aim for?
[19:59:41] <Sync> _abc__: you overcomplicate the act of measuring the spindle position, it really is that simple
[19:59:45] <Sync> 90°C is fine
[19:59:58] <Sync> if you are scared, 70°C
[20:00:15] <enleth> OK, that sounds reasonable
[20:00:42] <Sync> just be warned, you only get one shot
[20:00:59] <Sync> so on it goes and no messing about
[20:01:11] <enleth> Freezing the spindle is another problem, it won't fit in the freezer I have, and I got rid of the big beer keg freezer
[20:01:27] <Sync> just get some dry ice from the supermarket
[20:01:56] <Sync> or simply put it in the fridge, everything that increases your temperature difference gives you more clearance
[20:02:57] <_abc__> I find meat freezer for 2 hours followed by gas torch applied locally helps a lot...
[20:03:08] <XXCoder> Sync: make your own ref
[20:03:19] <XXCoder> buy dry ice and ice cooler
[20:03:52] <XXCoder> it should last long enough for your task
[20:03:54] <Sync> gas torch is risky, as you might overheat the bearing
[20:04:04] <MrSunshine> i wish supermarkets in sweden had dry ice
[20:04:13] <MrFluffy> $300 bearing, $20 junkyard freezer purchase to install, sounds good to me.
[20:04:26] <MrFluffy> it only has to work once before you take it back
[20:04:30] <Sync> they do, MrSunshine, almost all of them get it in delivery
[20:04:55] <MrFluffy> you can buy dry ice from specialist cookery suppliers now
[20:04:55] <MrSunshine> never seen it for sale atleast
[20:05:22] <Sync> yeah because nobody would buy it
[20:05:25] <MrFluffy> google for near you, you have to order it but it comes in a poly container to pick up
[20:05:26] <Sync> ask the fish counter for it
[20:05:33] <Sync> or oder it, yeah
[20:06:06] <MrFluffy> I found a outlet within 30km of my house in rural france that would sell me a block of dry ice in this way
[20:06:44] <MrFluffy> because we were going to be dropping it in a intercooler we needed a source, and it ended up being a food supply wholesaler
[20:07:19] <MrFluffy> in the isolated container it will last a day or two

[20:10:19] <MrFluffy> rotational speed of spindles peaking at 1600rpm. So far a 20b chain is looking cheapest...

[20:23:32] <MrFluffy> that gives you the adjustability of a old boat style toolpost with a modified taig toolpost, but you still have to set the tool on centre each change
[20:24:31] <dr0w> I saw that guy's modification. wondered if I could find a woodruff key that size
[20:24:55] amnesic_away is now known as amnesic
[20:24:58] <MrFluffy> or saw it out of a steel round?
[20:25:22] <dr0w> true
[20:25:44] <MrFluffy> do you have access to a mill to cut the curved hollow would be the more important awkward bit
[20:26:24] <MrFluffy> or another lathe, mount it off centre in a four jaw or on a faceplate and turn the shape in
[20:27:14] <dr0w> ahh.. I didn't even consider turning it..
[20:27:23] <MrFluffy> thats the real problem with modifying lathes, you always need another one to finish it in the middle of the job :)
[20:27:30] <dr0w> interpolating it in a mill would be the challenge
[20:27:57] <dr0w> I might be able to cash a favor if I had my ducks in a row

[20:28:19] <MrFluffy> draw the cut in cad if you have access to a cnc, or make another toolpost with that shape in while your at it
[20:29:04] <MrFluffy> or mount on a rotary on a manual mill, just crank it round which is what that author has done
[20:32:15] <MrFluffy> lot of interesting mods on that page... you dont need a industrial machine to be clever about things
[20:33:53] <MrFluffy> its easier to just keep the shims with the toolbit with some rubber bands tho...
[20:34:04] <dr0w> yeah.. I saw a handful of ideas I'd like to 'borrow'
[20:36:02] <Sync> MrFluffy: a chain probably is the easiest
[20:38:56] <MrFluffy> I'm after cheapest, because I'm a cheapskate and its my money :)
[20:39:19] <MrFluffy> but I also have to stand near it in use...

[20:52:47] <SpeedEvil> if you have round problems, you probably want a lathe.

[22:26:06] <zeeshan> like 20x22
[22:26:31] <Tom_itx> mine looks small because i put a center wall in it
[22:26:36] <Tom_itx> i could remove it
[22:26:44] <zeeshan> you mean dual doors
[22:26:46] <zeeshan> vs 1 large door?
[22:26:50] <Tom_itx> uh huh
[22:26:57] <zeeshan> yea
[22:26:59] <zeeshan> thats not great
[22:27:03] <Tom_itx> i had a 'shop' in one side for a while
[22:27:14] <zeeshan> that was one of the criteria when i was buying this house
[22:27:18] <zeeshan> large isngle door
[22:27:26] <zeeshan> cause you can move the car in at whatever angle
[22:27:26] <Tom_itx> i built the garage
[22:27:31] <zeeshan> ah!
[22:27:37] <zeeshan> dude im so happy
[22:27:41] <zeeshan> i haven't been this happy in a while :D
[22:27:48] <zeeshan> it's actually going to fit!
[22:28:34] <Tom_itx> where's the mill?
[22:28:47] <zeeshan> in the corner :P
[22:28:52] <zeeshan> look at the very right side
[22:28:57] <zeeshan> its peaking out
[22:28:59] <Tom_itx> yeah i see it now
[22:29:36] <Tom_itx> the lathe makes it look like a toy
[22:29:40] <zeeshan> haha
[22:30:26] <zeeshan> dude
[22:30:39] <zeeshan> im kinda iffy about using my machine jack that i built
[22:30:41] <zeeshan> to lift this thing
[22:30:48] <zeeshan> i designed it for 8000lb
[22:31:08] <Tom_itx> not the cherry picker?
[22:31:17] <zeeshan> cherry picker wont even move it
[22:31:17] <zeeshan> lol
[22:31:32] <zeeshan> but you made me think of something else
[22:31:41] <zeeshan> since all im trying to do is lift it and put it on skates
[22:31:51] <zeeshan> i could share the load between the toe jack and hoist

[22:34:14] <zeeshan> noo
[22:34:18] <zeeshan> i got 3/8 steel plate
[22:34:23] <zeeshan> and machine feet for it
[22:34:30] <zeeshan> ill sit it on that
[22:34:33] <zeeshan> and then level it
[22:34:48] <zeeshan> not going to worry about that till i have the machine running though
[22:34:53] <Tom_itx> is 3/8 enough?
[22:35:04] <zeeshan> yes
[22:35:07] <Tom_itx> probably...
[22:38:37] <malcom2073> Damn heh zeeshan, that barely fit vertically

[22:46:09] <andypugh> I only have two working lathes at the moment. Unless you count the one that I keep in my dad’s workshop :-)
[22:46:30] <andypugh> I am fairly sure that I don’t actually need 4 lathes.
[22:47:16] <zeeshan> fix mine!

[22:53:34] <PetefromTn_> heh no not at pepboys
[22:53:44] <svh> so gecko g540, any other place to get a good deal
[22:53:45] <PetefromTn_> BB in a bit gotta eat dinner
[22:53:57] <svh> flea-bay seams to have the best deal so far with the 48vdc controller
[22:54:05] <svh> er. PSU
[22:54:24] <svh> anywho. i'll keep digging but it appears it doesn't get any cheaper than $300 with the power supply
[22:54:44] <andypugh> What is it that you like about the G540?
[22:54:56] <svh> not sure, anything equivalent.

[22:58:10] <svh> ha.
[22:58:24] <andypugh> I think I would be loking at individual drivers, and possible mains-input ones.
[22:58:39] <andypugh> The more volts the better where steppers are concerned.
[22:59:41] <svh> anything will be better than 18IPM
[22:59:42] <svh> ;p
[22:59:50] <svh> that is the most i can get out of this controller
[23:00:35] <svh> and rather than mod it with the hex inverter opt to get a new one

[23:03:08] <svh> interesting
[23:04:05] <andypugh> Next to me on the floor I have 1kW servo that is going on my lathe. That is 2Nm rated too....
[23:04:16] <zeeshan> cute
[23:04:28] <andypugh> And it’s about the size of a shoe box.
[23:04:29] <Praesmeodymium> thats the kind of thing I have power for
[23:05:11] <zeeshan> andypugh: i was looking at the servos
[23:05:15] <zeeshan> wtf
[23:05:19] <zeeshan> they got gear boxes on em
[23:05:28] <zeeshan> isnt that going to introduce backlash
[23:05:43] <andypugh> Gearboxes or harmonic drives
[23:05:45] <andypugh> ?
[23:05:51] <zeeshan> looks like gear boxes
[23:05:53] <zeeshan> i cant tell
[23:05:59] <zeeshan> it bolts directly to the servo
[23:06:28] <andypugh> Maybe they are zero-backlash drives somehow. It seems likely that Okuma knew what they were doing...

[23:39:28] <jdh> have yet to try an entire wheel so far.
[23:40:19] <JT-Shop> I removed all the outer spokes from both sides then changed the inners one at a time... measure the offset before you take it down lol
[23:40:34] <Roguish> JT: getting the spoke tension uniform is a real challenge.
[23:41:02] <JT-Shop> yea, I can play a tune on mine lol
[23:41:49] <Roguish> I gave up building my wheels long ago. Have a friend who is a really, really good bike mechanic. only charges me $50 a wheel and includes the spoke. his wheels are near bullet proof.
[23:42:35] <JT-Shop> can't beat that
[23:43:29] <Roguish> yeah, I've tried, but gave up. this guy worked for Mavic neutral support in the Tour de France in the 80's.
[23:43:31] <renesis> i think dans comp did mine free when i bought the parts
[23:43:36] <renesis> maybe not
[23:44:12] <Roguish> but if you can build your own wheels, more power to ya. !!!!!
[23:44:30] <renesis> neat faq says free, $15/wheel if you send them parts
[23:44:42] <JT-Shop> it's not too bad, but you can get out of wack real quick if your not paying attention
[23:44:51] <renesis> heh, they maybe just do BMX wheels
