[00:09:36] <FrankZappa> cool, tjtr33
[00:09:45] <FrankZappa> I meant large structural tube
[00:09:58] <FrankZappa> 3 axis also
[00:10:33] <FrankZappa> 48" (1.2 m) radius or larger
[01:15:05] <CaptHindsight> how do those machines work without a single duino board involved? :)
[02:05:03] <Deejay> moin
[02:37:31] <SpeedEvil> CaptHindsight: Impossible!
[03:11:47] <miss0r> I just got my hands on an Arboga u2508 mill. is it worth my while?
[03:15:03] <archivist> good for general purpose manual work I suppose
[03:15:42] <miss0r> I was thinking of fitting it with stepper motors and do some CNC control
[03:16:34] <archivist> the column design would make difficulties there
[03:16:52] <miss0r> column design?
[03:17:12] <archivist> you have two separate Z movements
[03:17:18] <miss0r> indeed.
[03:17:49] <miss0r> I could just attach it to the one moving the spindle up and down. If more movement is nesessary I could just move the other one by hand and reset it from there
[03:17:51] <archivist> and you need to clamp the lower one before milling
[03:18:17] <miss0r> but quality wise you'd say it's a good machine?
[03:18:45] <archivist> looks ok as a manual :)
[03:20:27] <archivist> head rotation would be interesting to cnc
[03:20:33] <miss0r> sweet. I got it for free. I saw it yesterday standing outside a metal factory in the rain, all rusted up. So I asked them, and I took it home(And holy jesus it is heavy!) I spend 5 hours yesterday shining it up, now everything moves smoothly
[03:21:23] <archivist> that is the correct price :)
[03:21:44] <miss0r> indeed... I need to buy this part:
http://www.ebay.co.uk/itm/ARBOGA-U2508-MILLING-MACHINE-SPINDLE-NUT-/201086530499?pt=UK_Home_Garden_PowerTools_SM&hash=item2ed1b0f3c3
[03:23:35] <archivist> or make that part
[03:23:51] <miss0r> Perhaps it is on there. Just that stuff is still rusted in place
[03:24:40] <archivist> you could revisit and ask if there was a tray of tooling left inside :)
[03:25:33] <miss0r> They didn't. I already asked them.
[03:25:52] <miss0r> The bit is on there. It is just still stuck
[03:26:28] <miss0r> I am going to need some part that goes inside that nut to actualy hold the tools
[03:31:43] <Einar1> I have an Arboga pillar drill very similar to that mill. I can't imagine they throw such machines out and still people pay good money for Chinese crap!
[03:32:58] <miss0r> In Denmark, atleast, the metal processing factories are not realy 'on the internet' yet. They have no idea about reselling stuff like this, so it is a great way to find good hardware by contacting them
[03:35:03] <Einar1> Here in Norway a lot of it goes on finn.no. Some at reasonable prices, but some are real fishing trips!
[03:35:30] <Einar1> In Sweden try blocket.se
[03:35:55] <miss0r> In denmark we have guloggratis.dk & dba.dk
[03:39:28] <Einar1> I found this:
http://www.finn.no/finn/torget/annonse?finnkode=47234940&folderId=1213779 but I still have 2 cars in my workshop I need to get out of there to make space. ;-)
[03:39:58] <miss0r> what a beauty
[03:40:52] <Einar1> Not exactly a beauty, but look at all the tools tha come with it. That's where you'll normally spend money after the conversion is done.
[03:40:59] <miss0r> Tomorrow I will go my a friend of mine place of work, and build my new cnc mill on this:
http://www.directindustry.com/prod/hermle/5-axis-cnc-vertical-milling-machines-16486-570386.html
[03:41:21] <miss0r> We already did all the parts in solid works
[03:41:50] <Einar1> Nice hobby machine ! :-) Where in Denmark?
[03:42:07] <miss0r> hehe. This is a place called GN
[03:42:40] <miss0r> They make hearing aids. he works with milling the plastic cast forms
[03:43:26] <Einar1> I'll be in Viborg at Mercantec next month.
[03:43:51] <miss0r> teaching?
[03:44:23] <Einar1> No. We're metalshapers from around the world meeting there.
[03:44:35] <miss0r> sweet :)
[03:44:56] <Einar1> http://www.metalmeet.com/
[03:45:26] <miss0r> Sounds like fun. can anyone pop their head in?
[03:46:55] <Einar1> Not really, but I've never seen anyone thrown out in the years I've been there. ;-) But you really should contact the organizer.
[03:47:07] <miss0r> indeed
[03:47:42] <miss0r> hmm... it is a 3½hour drive.
[03:49:12] <Einar1> I think you may need to be logged in to see this?
http://www.metalmeet.com/forum/showthread.php?t=11406
[03:49:49] <miss0r> I can see it. I will consider showing up
[03:50:15] <miss0r> I have some family near viborg I should realy visit some more :)
[03:50:50] <Einar1> If you do show up, contact me. And ask Anders to be polite.
[03:51:00] <miss0r> indeed
[03:53:26] <Einar1> Have to go and get one of the cars down from the lift and into another garage. I need to get another in to get out the engine so I can swap it with the car that's now on the lift.
[03:53:46] <miss0r> I think I need to find a new home for my scantool drilling machine. (space issues). This arboga will need to take over than function
[03:54:16] <Einar1> You will never regret making space for the Arboga.
[03:54:21] <miss0r> meh. I know the feeling. I am restoring a 88" Landrover 2.25 petrol 1972
[03:54:39] <miss0r> I build a new frame from scratch
[03:55:45] <Einar1> Sounds like a real restoration! Starting from the bottom. OK, have to go ...
[03:55:52] <miss0r> have fubn
[03:55:56] <miss0r> -b
[03:56:39] <miss0r> should you be interrested:
http://i820.photobucket.com/albums/zz122/Garfield87/IMG_1460.jpg
[03:56:55] <miss0r> i'm out
[04:53:47] <MrSunshine> yeah! finaly a Z home/pos limit swtich installed
[04:54:12] <MrSunshine> no more slamming into hard stop of Z messing up Z position, and no more probe move screaming about would exeed Z maximum travel!
[05:24:24] <jthornton> yea
[06:16:06] <SpeedEvil> Limits are important in life.
[06:17:11] * archivist hates limits
[06:19:43] <archivist> a way to ignore limits, use a crane...

[06:58:46] <Loetmichel> <- is just catching up with the fuel consumption list of my car. easy when you make a photo with the cellphone of every fuel bill beside the distance counter in the tachometer. just to transfer it into
https://www.spritmonitor.de/de/detailansicht/442560.html is some tedious work if you have to catch up a year at least ;-) $me is a bit lazy sometimes ;-)
[06:59:53] <archivist> s/sometimes/always :)
[07:00:24] <Loetmichel> bah!
[07:00:32] <Loetmichel> btw: did you see the enclosure?
[07:01:20] <archivist> I saw your comment when I got back but failed to follow the link
[07:01:48] <archivist> I saw the make, repeat till fit
[07:01:56] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14877
[07:02:50] <Loetmichel> worked out fine, just had to make the lid twiche because of the lapse to make it the same width as the bottom ;-)
[07:04:47] <Loetmichel> the seet bending by cutting a half sheet thickness slot at the desired bend wors great
[07:04:53] <Loetmichel> sheet
[07:06:50] <archivist> you are having too much fun at that job
[07:08:56] <Tom_itx> Loetmichel using an engraving bit?
[07:09:09] <Loetmichel> 2mm end mill
[07:37:36] <Loetmichel> archivist: why? is it forbidden by law to have fun at the job?
[07:39:14] <archivist> you are easier to wind up that a clock :)
[07:39:19] <archivist> than
[07:41:04] <Loetmichel> wind up?
[07:41:32] <Loetmichel> is that "getting excited" or "getting upset"?
[07:43:16] <archivist> "taking the bait"
[08:40:56] <Loetmichel> hrhr, my wife just bestowed a t-shirt on me: front writing: "the early bird..."below a line-art bird. Back writing: "...catches one if it isnt quiet!" below a unconcoius bird on its back ;-)
[08:54:10] <Loetmichel> soo, up to date with the fuel bills... and still for 90km fuel in the tank.. the omega is drinking a bit much i think...
https://www.spritmonitor.de/de/detailansicht/442560.html
[09:00:30] <Einar2> Then you should buy this "krankenstuhl":

[09:13:35] <Jymmm> Loetmichel: Becasue an elephant wearing roller skates would be cool!
[09:15:29] <Jymmm> Loetmichel: ...and TOTALLY AWESOME if she was a roller derby gal

[11:36:39] <XXCoder> IchGuckLive: hows ya
[11:37:11] <IchGuckLive> its raining outside and we got a big party in town :-(
[11:38:02] <XXCoder> oh aw
[11:38:58] <CaptHindsight> http://www.digikey.com/product-search/en?vendor=10&keywords=panasonic+pgs look at the thermal conductivity compared to aluminum or copper

[11:51:59] <michiD> hallo ist jemand hier der sich mit die endschalter auskennt? bei linuxcnc
[11:53:18] <IchGuckLive> ja
[11:53:26] <IchGuckLive> ich sitze in kaiserslautern
[11:53:53] <michiD> ich nähe magdeburg
[11:54:06] <IchGuckLive> bitte drück mal auf meine nick
[11:57:26] <PetefromTn_> http://imagebin.org/310079 BEAUTIFUL....LOL
[11:58:16] <Khoal_mIRC> I am jealous!
[11:58:46] * SpeedEvil sighs.
[12:01:28] <PetefromTn_> hehe I did not really want to spend that much cash but now that it is here man I am pleased I did. there are of course more expensive vises out there but this is all I could afford.
[12:02:47] <AggieMEEN> It's a good investment. All the mills in our machine shop use those, and they're great.
[12:03:39] <PetefromTn_> yeah me too. The shop I work in has a bunch of them all KURT. This is the D688 which is the newer ones they have and I really like them.
[12:06:37] <IchGuckLive> AggieMEEN: dio you got a swiss AGIE
[12:07:36] <FrankZappa> kurt good
[12:07:43] <FrankZappa> swappable jaws good
[12:08:08] <AggieMEEN> IchGuckLive: No, AggieMEEN is because I am a graduate of Texas A&M University (an Aggie) and a mechanical engineer (MEEN). :)
[12:10:06] <IchGuckLive> texas got alot of water this week
[12:10:18] <FrankZappa> Chexis
[12:10:38] <IchGuckLive> texas university got nice cheerleaders but they changed the dress in 2010
[12:10:45] <AggieMEEN> That is a good thing. TX has been under a drought for so long
[12:11:15] <IchGuckLive> long drought means high flood
[12:12:01] <AggieMEEN> Yes, flash floods can be a problem there.
[12:13:19] <AggieMEEN> Hopefully the rain will reduce the chances of wildfires this summer. 2011 was really bad for those.
[12:13:22] <PetefromTn_> Damn it is nice to tram in the vise and have it show NO movement across the entire jaw and then take the DTI across the ways of the vise and have the same thing. KURT RULES!!
[12:13:25] <CaptHindsight> http://www.ebay.com/itm/Hitachi-Seiki-VM-40-/271471024038 didn't even sell for $2k
[12:14:39] <XXCoder> too bad
[12:15:01] <XXCoder> maybe bad location or no owner with nesscary mover to cartry it wanted it
[12:15:08] <XXCoder> carry
[12:19:21] <PetefromTn_> fixed jaw is perfectly square to the bed. I feel like a kid at Christmas .
[12:19:36] <FrankZappa> cool
[12:19:39] <FrankZappa> congrats
[12:19:43] <FrankZappa> what are you gonna make?
[12:20:41] <PetefromTn_> well all sorts of stuff. I have some custom scope riser rails I have been making and selling and I just got a customer wanting some custom parts for Mazda RX7 twin turbo cars here I am working on.
[12:20:53] <SpeedEvil> CaptHindsight: damn
[12:20:56] <PetefromTn_> I have been using a cheap Shars CNC vise and it has been less than stellar.
[12:21:19] <PetefromTn_> I am gonna try to regrind it at the shop I am temporarily working in to get it flat and square.
[12:21:35] <PetefromTn_> then I can use it for dual vise second op setups and such.
[12:22:37] <FrankZappa> heavy parts?
[12:23:53] <PetefromTn_> no nice small precise parts. aluminum.
[12:24:14] <PetefromTn_> I will let the shop I work in handle the real heavy stuff. I don't even have a fork truck here LOL.
[12:24:33] <FrankZappa> cool
[12:24:37] <PetefromTn_> Damn vise is so nice and shiny I am afraid to cut anything on it now damnit LOL
[12:26:21] <CaptHindsight> http://www.ebay.com/itm/KURT-VISE-D100-8-vise-with-9-75-opening-NEW-/271168152286 really? $3k
[12:27:19] <CaptHindsight> just soak in bleach and a little vinegar to make it look worth using :)
[12:29:00] <PetefromTn_> We have some of those 8" ones at work. They are really huge. and stupid heavy. We have to use the gantry to load them into the machines.
[12:30:39] <PetefromTn_> http://s177.photobucket.com/user/pirellip/media/IMG_20140130_170335.jpg.html Just bought a rifle like this without the custom stock and Leupold scope etc. I am gonna try to build it to look just like that beauty.
[12:32:39] <CaptHindsight> http://i.imgur.com/vne5E.jpg we didn't have this when I was a kid :(
[12:33:16] <PetefromTn_> Got a smokin' deal on it too.
[12:33:16] <PetefromTn_> Now I need to sell some damn parts here to pay for a nice scope so I can get back into Field Target Competitions.
[12:36:57] <PetefromTn_> God help us LOL
[12:44:36] <XXCoder> only 6??
[12:44:38] <XXCoder> lol
[12:44:55] <XXCoder> that said, I saw pet cop sjow where they went to arrest cat hoarder
[12:45:09] <XXCoder> there was over 200 cats. nearly all was put to sleep due to serious health issues
[12:47:56] * Tom_itx wonders if PetefromTn_ has dinged up his new vise yet
[12:51:22] <archivist> to busy cleaning the vice to be using it
[12:51:50] <zeeshan|2> archivist: give me your levels !
[12:51:51] <zeeshan|2> :]

[13:01:37] <PetefromTn_> seriously? hehe
[13:02:42] <PetefromTn_> Got my vise trammed in, got my part zeroed, got the program almost done. Gonna go sit down and finish the Cam work and get this bitch cutting LOL..
[13:03:51] <PetefromTn_> I really need to get myself a nice heavy rubber mallet with replaceable heads so I can smack down the parts easier. This rubber mallet is simply not heavy enough.
[13:04:33] <archivist> if clean why do you need to smack down :)
[13:05:38] <PetefromTn_> I always like to smack it down to make sure my parallels are solid and the part is as flat as I can possibly get it. I will say that it MUCH easier on this new kurt LOL
[13:06:12] <PetefromTn_> Local Radio station is playing Stayin' Alive by the Bee Gees.... Damn that is a great song my wife is dancing here to it LOL
[13:10:52] <IchGuckLive> pete go to cmdline an make a tracert to a faforit www to see what pc are involved and lock your search

[13:37:48] <zeeshan|2> if you guys search
[13:37:49] <zeeshan|2> 456MAZ
[13:37:51] <zeeshan|2> on ebay
[13:37:53] <zeeshan|2> what comes up?
[13:40:02] <SpeedEvil> Nothing
[13:40:13] <zeeshan|2> weird
[13:40:14] <zeeshan|2> so weird
[13:40:31] <SpeedEvil> Oh - if I re-click worldwide, a caliper
[13:41:06] <zeeshan|2> ah
[13:41:08] <zeeshan|2> okay good
[13:41:17] <zeeshan|2> ebay's changed their stuff
[13:41:31] <zeeshan|2> you have to select 'international; shipping'
[13:41:32] <zeeshan|2> specifically
[13:41:39] <zeeshan|2> so it gets visible to people from usa
[13:41:46] <zeeshan|2> it wasn't like that a couple years ago!
[13:42:27] <SpeedEvil> My last search was for UK only, as I want stuff to arrive quickly
[13:42:34] <zeeshan|2> ahh i see
[13:42:54] <SpeedEvil> And - well - drill presses aren't likely to ship economically
[13:43:36] <zeeshan|2> haha yea..
[13:43:40] <zeeshan|2> thats something id buy locally
[13:43:43] <zeeshan|2> never through ebay
[13:43:54] <SpeedEvil> Ebay does local too
[13:44:05] <zeeshan|2> oh
[13:47:00] <SpeedEvil> http://www.ebay.co.uk/itm/RJH-FERRET-TOOL-LAPPER-3-PHASE-REVERSABLE-3000-RPM-/321393668891?pt=UK_BOI_Metalworking_Milling_Welding_Metalworking_Supplies_ET&hash=item4ad48e331b is the only really local tool to me
[13:47:09] <SpeedEvil> Which unless I'm confused is a ridiculous price
[13:48:50] <zeeshan|2> hehe
[13:49:37] <archivist> make an offer £3.99
[13:49:43] <Loetmichel> 400 pounds for a single disc grinder fitted with a rubber wheel?
[13:49:48] <Loetmichel> i dont think so
[14:49:22] <Jymmm> CaptHindsight: That's still $37/sq ft for a fancy pencil =)
[16:26:22] <jdh> http://raleigh.craigslist.org/tls/4463330703.html
[16:26:26] <jdh> I'll be near that tomorrow
[16:56:00] <Deejay> gn8
[18:19:20] <FrankZappa> hiya folks
[20:08:53] <ebrummer> I'm using a 5i23 connected to a 7i49 on the first set of ios and a 7i42TA on the second set of ios. I'm using these files: freeby.mesanet.com/hm2-servosrt.hal freeby.mesanet.com/5i23-srt.ini (with the ini file pointing to the sv6_7i49.bit num_pwmgens=3 num_resolvers=3 sserial_port_0=000XXXXX)
[20:10:22] <ebrummer> i've got my x axis servo amp wired up to the the 7i49 and the resolver for it as well. Right now with a voltmeter I'm reading a 1.4v differential across x+ and x- without doing anything with linuxcnc (which moves my x axis upon enabling the drive)
[20:13:36] <ebrummer> the y axis does not have this from the 7i49
[20:22:15] <jdh> PCW often magically appears for these things. Stick around and wait.
[20:24:52] <pcw_home> if you have 1.4V on the AOUT pins and pwmgen.00.enable is false the 7I49 is faulty (or there is a connection/cable problem)
[20:26:09] <jdh> close enough to magic
[20:27:07] <ebrummer> thank you jdh and pcw_home; i think there's an error on my end before I continue harassing anyone here or suspecting board failiure
[20:29:29] <pcw_home> I would first disconnect the AOUT pins from the drive and measure channel 0 analog out (P4 pin 20)
[20:29:30] <pcw_home> when just powered up to make sure there is no board fault (also checking that 7I49 5V is OK at this point is not a bad idea)
[20:36:29] <ebrummer> everything seems in order on the 7i49 board side
[20:37:47] <ebrummer> so I start up LinuxCNC, I disable estop. I toggle the power on the machine. To do any motion I'm required to home. If I click home x axis, I get a joint 0 following error. Any thoughts or how to test the resolver input back into LinuxCNC via the Hal oscilliscope?
[20:38:25] <jdh> you can disable the home requirement
[20:39:17] <jdh> and you don't have to home to jog
[20:40:13] <ebrummer> I get a joint 0 when jogging as well and no movement
[20:47:56] <ebrummer> so based on the wiki, my ini file isn't setup right
[20:50:57] <jdh> could be lots of things.
[20:52:05] <jdh> disable the drive, spin the motor and see if the resolver phases change correctly in halscope?
[20:52:27] <jdh> check polarity of the analog output to the drive? resolver polarity?
[20:56:16] <pcw_home> just 'halmeter' resolver.00.position for example
[21:02:55] <ebrummer> using halmeter and halscope Im not getting anything on resolver.00.position when turning the resolver
[21:14:32] <pcw_home> with a DVM, can you check the ACV across the sine and cosine 7I49 input terminals as you turn the resolver?
[21:14:34] <ebrummer> pcw_home; in the documentation it says I need to specify the resolver frequency in resmod but if my understanding is correct, resmod is not used
[21:16:23] <pcw_home> you can set the resolver frequency but the default should work (2.4 KHz, 4.8 KHz and 9.6 KHz are selectable)
[21:16:33] <pcw_home> (on a 5i23)
[21:17:04] <ebrummer> 2.5k Resolver
[21:17:30] <ebrummer> where would I specify that?
[21:17:40] <ebrummer> hardware switch or ini file or?
[21:17:56] <ebrummer> I didn't get anything on AC at the input terminals
[21:18:43] <ebrummer> checking at the resolver now
[21:41:11] <pcw_home> best thing to do is start linuxcnc and then
[21:41:13] <pcw_home> halcmd show all > allhal.txt
[21:41:14] <pcw_home> in a terminal window so you know what hal pins/parameters are available
[21:41:16] <pcw_home> also
[21:41:17] <pcw_home> man hostmot2

[21:45:07] <XXCoder> http://basdebruijn.com/2014/05/machinekit-and-additive-manufacturing/ wow minor but important advance in 3d printing
[22:15:36] <p0st4L> any pointers on measuring backlash?
[22:19:02] <skunkworks_> pretty cool
http://hackaday.com/2014/05/10/blobless-printing-with-velocity-extrusion/
[22:20:46] <pcw_home> seems... obvious
[22:21:47] <XXCoder> skunkworks_: you missed my link lol
[22:21:50] <XXCoder> but yeah
[22:22:00] <skunkworks_> sorry - been away
[22:22:03] <XXCoder> np
[22:22:14] <pcw_home> been suggested for years
[22:27:29] <XXCoder> well guess finally its being worked on
[22:27:42] <p0st4L> if i jog an axis .1
[22:27:45] <p0st4L> and it goes .096
[22:27:55] <p0st4L> what the dilly yo
[22:28:03] <Jymmm> It kinda sucks in a way when a ebay seller would rather give you a refund and not have to return what you bought instead of getting nagative feedback
[22:28:11] <skunkworks_> backlash or scaling.. (or missed steps)
[22:28:20] <p0st4L> it would be backlash
[22:28:26] <p0st4L> since the scaling is correct (12 turns per inch)
[22:29:04] <p0st4L> backlash = .004?
[22:31:03] <pcw_home> does it move the correct amount on a second move in the same direction?
[22:31:12] <p0st4L> no, same each time
[22:32:09] <p0st4L> changed backlash on that axis to .004
[22:32:17] <p0st4L> now it's .0985 for .01
[22:32:40] <p0st4L> .0975*
[22:32:41] <pcw_home> so jog .1 moves 0.096, jog .1 again in same direction and its ?
[22:34:26] <pcw_home> so if it always moved too little after repeated jogs in the same direction, thats a scale error not backlash
[22:34:44] <p0st4L> ok then ya, seems to be scaling
[22:34:47] <p0st4L> since it goes .096
[22:34:51] <p0st4L> then .094
[22:34:52] <p0st4L> etc
[22:34:55] <p0st4L> err
[22:34:57] <p0st4L> .092
[22:35:21] <pcw_home> you may have backlash also but get the approx scale right first
[22:35:42] <p0st4L> so if i go .1 in 1 direction, then back and do it again
[22:35:48] <p0st4L> it's .005 shorter
[22:36:22] <pcw_home> what are you measuring with?
[22:36:41] <p0st4L> one of those dial things
[22:36:43] <p0st4L> i forget the name
[22:36:46] <p0st4L> dial indicator
[22:36:47] <p0st4L> or whatever
[22:37:15] <skunkworks_> is it square to the axis you are measuring?
[22:37:41] <p0st4L> yes
[22:38:00] <XXCoder> dial indicators dont seem to be too expensibve
[22:38:05] <XXCoder> anything to watch out for?
[22:38:13] <skunkworks_> cheap ones? ;)
[22:38:21] <XXCoder> define cheap
[22:38:42] <p0st4L> so
[22:38:44] <p0st4L> i moved .3
[22:38:48] <p0st4L> and back
[22:38:51] <p0st4L> and it's off
[22:38:57] <p0st4L> this is gonna be fun :/
[22:39:09] <XXCoder> skunk like is it below $10 or below $500
[22:41:25] <pcw_home> to separate backlash from scale errors you should jog twice in
[22:41:27] <pcw_home> the same direction and check the distance moved in the second jog
[22:42:46] <p0st4L> distance moved from jog1 to jog2?
[22:42:51] <p0st4L> or from 0 to jog2?
[22:43:19] <pcw_home> 1 to 2
[22:44:02] <p0st4L> for every .01 i go, it goes .0095
[22:44:35] <pcw_home> even without changing direction?
[22:44:44] <p0st4L> correct
[22:44:53] <p0st4L> so that would be scaling, right?
[22:45:39] <p0st4L> lead screw pitch is 5 turns per inch
[22:45:42] <p0st4L> and that's whats in config
[22:47:39] <pcw_home> well maybe its 5.2 TPI...
[22:48:05] <p0st4L> yeah how would the math work out on that? guess i just gotta do small incriments
[22:48:47] <pcw_home> I would move further than .1 to set scaling though (whats the range of your indicator?)
[22:49:19] <p0st4L> 1 inch max
[22:49:32] <p0st4L> could it be the steps per revolution from the stepper motors?
[22:49:38] <p0st4L> or just screw with 1 thing at a time?
[22:53:21] <pcw_home> Not sure what it is
[22:54:49] <p0st4L> it's in stepconf
[22:55:06] <p0st4L> but it's ok. ill play w/ the scaling of rev/inch and see if i cant get it to be a little closer';
[23:31:05] <Connor> Anyone know anything about this company? Looking to get some collets.. this looks like a nice set.. cheaper than Shars... same specs...
