[00:39:24] <XXCoder> its offset by height not distance to each other lol
[00:39:31] <XXCoder> simple solution though
[00:39:42] <XXCoder> just move ball screw and rails up

[00:41:57] <ssi> look it up before you dismiss me
[00:41:58] <RyanS> I am putting quick and dirty and coolant system on my 4 x 6 bandsaw, you think 3 L a minute is sufficient?
[00:42:20] <XXCoder> 1ML/ms
[00:43:03] <RyanS> umm
[00:43:45] <RyanS> 50ml/s ......
[00:44:19] <XXCoder> 60000000000 liters a minute
[00:44:23] <jdh> I have oldhams on my mill
[00:44:31] <SpeedEvil> RyanS: 1mL/s of water heated by 50C will cool by 200W
[00:44:36] <XXCoder> thats what my suggestion was LOL. I bet it'd be so fast it'd cut stock by itself.
[00:45:23] <SpeedEvil> RyanS: 50ml/s is quite adequate for anything sensible if you can get all of the coolant to the cutter
[00:45:39] <ssi> ok I'm about to cut a big part with a lot of pierces, I only have one piece of metal big enough
[00:45:40] <SpeedEvil> more may be an idea if you can only get a tiny fration
[00:45:50] <ssi> lets hope my thc crap doesn't ruin this one shot
[00:46:08] <SpeedEvil> Good luck
[00:46:09] <XXCoder> good luck and do a air cut first
[00:46:23] <SpeedEvil> Or a polystyrene cut
[00:46:37] <XXCoder> thats better but if can afford or buy
[00:46:45] <ssi> air cut doesn't help
[00:46:53] <ssi> it only is a problem when the thc is running
[00:47:23] * SpeedEvil just took delivery of 12m^3 of foam.
[00:47:47] <RyanS> Why do some bandsaws have coolant nozzles over both blade guides? Is it simply for larger machines?
[00:48:28] <SpeedEvil> RyanS: helping chip flow?

[00:52:26] <RyanS> how about an agricultural pump..... say 50l a second :)
[00:52:57] <RyanS> It would be flood in every sense of the word

[00:58:06] <ssi> I guess that was too much to ask for :(
[00:58:17] <ssi> being able to use 'run from here' is too much to ask for also
[00:58:44] <RyanS> That's a good point vertical bandsaws don't use the coolant, and presumably they use bimetal

[11:32:11] <kfoltman> hi Loetmichel
[11:32:52] <kfoltman> Loetmichel:
http://i.imgur.com/1RPWRNn.jpg
[11:33:19] <kfoltman> mostly software issues now :)
[11:33:33] <archivist> and backlash
[11:33:37] <Loetmichel> kfoltman: hmm, there seems to be some step loss between drilling and isolating, otherwise looks good
[11:33:46] <kfoltman> Loetmichel: no, it's scaling bug due to bad DPI setting
[11:33:49] <kfoltman> at least 1.5mm of it
[11:33:54] <Loetmichel> ah
[11:34:05] <Loetmichel> but you seem to have a LOT of backlash
[11:34:09] <kfoltman> I used roll-my-own (and buggy) stuff to generate gcode
[11:34:34] <archivist> the jaggies around a circle a a sign of backlash
[11:34:45] <Loetmichel> (look for the uppermost circle on the right)
[11:35:01] <kfoltman> yes, that looks very backlashy
[11:35:20] <Loetmichel> kfoltman: you have seen the vid and the result of mine?
[11:35:24] <kfoltman> yes
[11:36:03] <kfoltman> so, anyway: the speed is OK now, the depth is relatively consistent (not 100% but no longer all over the place)
[11:36:14] <Loetmichel> yeak
[11:36:19] <Loetmichel> -k+h
[11:36:32] <kfoltman> so I have some vibration issues, bad tool mounting leading to tool wandering (and possibly some backlash there)
[11:36:34] -!- gsagie [gsagie!~gsagie@46-117-207-239.bb.netvision.net.il] has joined #linuxcnc
[11:36:37] <Loetmichel> but you should do something about that backlash
[11:36:40] -!- gsagie [gsagie!~gsagie@46-117-207-239.bb.netvision.net.il] has parted #linuxcnc
[11:36:57] <kfoltman> oh, and the Y axis doesn't seem very stable in terms of mounting
[11:37:06] <kfoltman> so the backlash might come from that I suppose
[11:37:15] <Loetmichel> depends
[11:37:23] <Loetmichel> do you use mormal threaded tods?
[11:37:33] <kfoltman> 1605 ballscrew
[11:37:39] <Loetmichel> or trapezodial/ballscrews?
[11:37:42] <kfoltman> the ballscrew is mounted to a board that's a bit wobbly
[11:37:49] <Loetmichel> hmm, ballscrews shouldnt have backlash
[11:38:00] <kfoltman> the rails are mounted correctly, but the bearings for the backlash are not
[11:38:03] <Loetmichel> maybe there is some slack in the mounts
[11:38:08] <kfoltman> yes, definitely
[11:39:18] <kfoltman> I'm going to spend some part of the holidays thinking about how to improve the software, then fix the hardware after coming back home :)
[11:41:16] <Valen> ballscrews can totally have backlash
[11:41:26] <Valen> even with anti-backlash nuts
[11:42:02] <kfoltman> Valen: but not 1mm or so
[11:42:16] <Valen> ok yeah one would hope for less than that ;->
[11:42:43] <kfoltman> Valen: in this case, I'm definitely willing to trust the Chinese manufacturers over myself :>
[11:43:10] <kfoltman> it's my first mechanical project, after all
[11:45:06] <kfoltman> bbl
[11:46:37] <Loetmichel> Valen: but not in the half-millimeter-range
[11:46:46] <Loetmichel> that would be VERY unusual
[11:47:20] <Valen> i dunno half a mm if it wasn't specced for anti-backlash might be possible
[11:47:28] <Valen> if it was specced for speed or something
[11:47:37] <Valen> I'd expect more like .1 mm though

[11:51:38] <Loetmichel> did you see the pic?
[11:51:55] <Loetmichel> [13:32] <kfoltman> Loetmichel:
http://i.imgur.com/1RPWRNn.jpg
[11:52:11] <Loetmichel> that is AT LEAST half a mm on the right topmost circle
[11:52:39] <Smidge204__> I guess those are supposed to be circles?
[11:56:18] <Loetmichel> i think so
[11:57:33] <Smidge204__> Looks like a lot going on in that pic
[11:59:40] <Loetmichel> ?
[12:00:04] <Smidge204__> Other than the non-circular holes, it looks like there might be some kind of calibration error?
[12:00:35] <Smidge204__> As you move down, the holes seem to be more and more offset from whre you'd expect them to be
[12:00:49] <Loetmichel> kfoltman said he had used a self-programmed gcode generator, with a bit of a scaling issue between drilling and isolating...
[12:01:01] <Smidge204__> That'd probably do it

[14:19:53] <jdh> another gorgeous day in appalachia?
[14:23:44] <ssi> morn
[14:26:26] <PetefromTn_> actually it is quite beautiful out today..
[14:26:47] -!- i_tarzan has quit [Ping timeout: 256 seconds]
[14:26:59] <PetefromTn_> I took my Husky out this morning and it was nice and sunny and not hot like it has been lately.
[14:27:11] <PetefromTn_> I think we are supposed to hit low 80's today.
[14:27:16] <PetefromTn_> Welcomed change.

[14:28:51] <PetefromTn_> I finally got my kitchen cabinet bases sanded and refinished. We went with a cream color with a brown glaze and some water based urethane that seems to be very solid. Just gotta get them installed here now and then rip out the wall cabinets.
[14:29:43] <PetefromTn_> Gonna be embellishing them with light rails, Crown, Crown base, some end finishings and then spray and reinstall.
[14:30:25] <PetefromTn_> Also got some new counter tops and a new white sink my wife wanted....that enamel and cast iron sink is a heavy bitch!!
[14:30:42] <PetefromTn_> what are you folks up to?
[14:30:43] <FinboySlick> PetefromTn_: I read your last two statements diagonally and I was thinking (why does he need light rails for his chickens?)
[14:30:58] -!- jduhls has quit [Ping timeout: 240 seconds]
[14:30:59] <jdh> Pete: all this for your hours that you want to get rid of?
[14:30:59] <PetefromTn_> chickens?
[14:31:07] <FinboySlick> I misread 'kitchen'
[14:31:12] <PetefromTn_> aah
[14:31:16] <PetefromTn_> hours?
[14:31:25] <PetefromTn_> you mean house?
[14:31:27] <jdh> your house.
[14:31:43] <PetefromTn_> yeah right now that is the only thing really keeping it from looking really nice inside.
[14:32:04] <PetefromTn_> We have ripped off a lot of the original trim inside too and we are refinishing it as well..
[14:32:12] prtksxna is now known as zz_prtksxna
[14:32:15] <PetefromTn_> Anything to make it more beutiful and sell easier right now.
[14:32:45] <PetefromTn_> Besides this is mostly just paint and some hard work I already had most of the wood and trim from other custom cabinet jobs I did recently as leftovers.
[14:33:05] <PetefromTn_> If it makes our home more beautiful hopefully it will sell faster.
[14:33:24] <PetefromTn_> Besides our kitchen has been kinda shitty for a long time now and my wife and I are over it LOL...
[14:34:00] <jdh> I actually made stuff with my new 6040 last night. still have some feed/speed issues for finish and chip removal
[14:34:00] <PetefromTn_> Trying to decide if I should just repair and refinish all the original doors or make all new ones on my shaper....
[14:34:11] <PetefromTn_> what did you make?
[14:36:03] <jdh> HDPE stand for my dive scooter
[14:36:15] <PetefromTn_> I got a 12 foot piece of 1/2 inch 6061 bar and some 3/4 inch aluminum 6061 round stock ordered today from my local supplier. I am supposed to pick it up this afternoon.
[14:36:33] <PetefromTn_> It is for a customer's project I hope to be making at least several of.
[14:36:42] <jdh> watch the whip
[14:36:45] <PetefromTn_> I love dive scooters.... what kind is it..
[14:37:01] <PetefromTn_> what whip?
[14:37:16] <jdh> http://www.silent-submersion.com/Products/Viper/Viper.html
[14:37:35] <jdh> I assume you are turning the round bar.
[14:38:22] <PetefromTn_> yeah but it will be getting cut down beforehand. The 12 foot piece of flat bar will be cut to 6' lengths at the supplier.
[14:38:28] <PetefromTn_> that looks like a nice one man.
[14:39:01] <PetefromTn_> I got to use one of those when I was doing dive training down in South Florida years back. Sure is nice to just push a button and haul ass underwater..
[14:39:28] <jdh> I made a cradle for it so it doesn't roll around on the boat
[14:39:29] <PetefromTn_> Do you get those kinda run times they are quoting?
[14:39:34] <PetefromTn_> Nice..
[14:40:00] <PetefromTn_> I remember the one we had was strong but did not last too long on the batteries so you had to be sparing with it.
[14:40:02] <jdh> I've never run that long but I've gone a mile in then a mile out on it.
[14:40:17] <PetefromTn_> sweet. Great for beach dives I guess..
[14:40:31] <jdh> caves

[14:43:24] <jdh> heh... guy here has an ancient bronco.. He's from .tn.us, license plate is 'SECFTBL"
[14:43:30] <PetefromTn_> Haven't got a tag on it yet but had to drive it around the neighborhood.
[14:43:50] <PetefromTn_> lemme guess.....it's orange and white LOL

[14:44:53] <PetefromTn_> I need to get my ass out there and wash and buff it out.
[14:45:44] <PetefromTn_> trying to figure out which aftermarket stereo to get for it. I had a sweet Alpine Bluetooth CD/USB in my Fiero GT that I should have not sold with the car. Thinking about getting one of those babies only their newest one.
[14:46:48] <PetefromTn_> JDH you need to get a Florida Gators sticker and tag his windshield with it or something when he is not looking. Make him really happy LOL.

[15:35:21] <ssi> it's a mendelmax style machine... those prints are pretty typical actually
[15:36:04] <ssi> just because most people print plastic moustaches with them doesn't mean they're not useful :P

[15:39:51] <jdh> I must be missing some fundamentals of 3d stuff
[15:40:02] <marmite> the item iwanto mill is 218x204mm and my machine cad mill 215x202mm
[15:40:28] <jdh> turn it diagonally and do it in 2 parts
[15:40:42] <marmite> cant do it in two parts :/
[15:40:44] <marmite> thats the issue
[15:40:49] <marmite> and i cant rotate it either
[15:41:06] <marmite> http://hackoteket.se/?attachment_id=36 its a hard thing to rotate
[15:41:12] <jdh> even better, buy/build a new machine
[15:41:22] <marmite> i wish
[15:41:27] <jdh> whip out teh angle grinder and increase your envelope
[15:41:53] <marmite> yeah not so much i need
[15:42:07] <jdh> knock a mm off each edge
[15:42:21] <marmite> i wounder of i could putt washers
[15:42:23] <marmite> on the corners
[15:42:33] <marmite> on every screw so it would fit
[15:42:34] <marmite> :D
[15:42:49] <CaptHindsight> I use paintbrushes to make my fake mustaches
[15:43:55] <jdh> make the two long corners out of a different material then pocket them to slip over the existing part.
[15:44:23] <jdh> or just get rid of everything below the pickup selector
[15:44:28] <marmite> jdh: good idea onley need to do it on the left
[15:44:30] <marmite> yeah exactly
[15:44:36] <marmite> take that corner
[15:44:39] <marmite> and do a pocket
[15:45:03] <kfoltman> I wonder how many of those things that normally require printers, can be done with clever jigs cut with CNC router
[15:45:18] <jdh> then get a new machine
[15:45:30] <jdh> internal voids are hard
[15:45:37] <jdh> unless you build in sections.
[15:45:52] <jdh> which is what I will do for my fan holder
[15:48:17] <marmite> hmm i will check if i can lose a couple off mm

[16:16:16] <jdh> might be some of those. hadn't thought about trying them.
[16:17:08] <PetefromTn_> I used to buy drop pieces from the local large machine and fab shop but they went out of business. Now I just try to buy from this supplier because he often beats the online prices pretty good.

[16:48:44] <jdh> hmm... blind urls

[16:52:18] <jdh> will the squareness of drilling/tapping matter much? seems like that will mostly be relative to what you are bolting to.
[16:53:17] <Jymmm> The cutting table just sits flush with the existing rulers in the machine, it's removeable not fastened in any way to the machine.
[16:53:46] <Jymmm> It's like an "insert" of sorts.

[17:04:31] <IchGuckLive> ;-)
[17:05:00] <IchGuckLive> kfoltman: kfoltman said he had used a self-programmed gcode generator, with a bit of a scaling issue between drilling and isolating.
[17:05:02] <IchGuckLive> WHY
[17:05:12] <kfoltman> why not?
[17:05:16] <IchGuckLive> isent there apcb 2 gcode you like
[17:05:30] <IchGuckLive> or just for fun
[17:05:56] <kfoltman> an excuse to make myself learn something that I would normally be too lazy to learn ;)
[17:06:29] <jdh> excellent reason.
[17:06:29] <kfoltman> also, I wasn't happy with existing pcb2gcode
[17:08:54] <IchGuckLive> ok up to you

[17:21:21] <Jymmm> Anyhow, what I was really asking for is suggests on alignment/fastening when the tools available are less than desired.

[17:26:25] <gene78> new 10.04.4 LTS install on lathe, old drive died. The cd went all thru the install, but on the reboot, grub (or bios) can't find a bootable drive!

[17:27:25] <gene78> So, you folks running atom mb's, what is he sata emulation set to in the bios? Its defaulted to IDE here.
[17:29:25] <Jymmm> Try ACPI
[17:30:00] <Jymmm> err AHCI
[17:30:41] <Loetmichel> hmmm, i just emptied my trousers front pockets... i think thats getting out of hand lately... (and i have 2 sticks lent away (8gb and 32gb) and have two sticks 64gb usb3 incoming friday... ;-) ->

[17:31:40] <gene78> Doing a re-install now with that setting
[17:32:09] <gene78> The bios warns about it though
[17:34:02] <K6MLE> I have installed the steppers on the machine, however, when jogging any of the axes, the motors appear to stall. What setting(s) in the HAL, or INI files can have an effect on that?

[17:36:56] <K6MLE> Being a newbie, I would like to know what setting(s) to change ... I've altered the acceleration rate, with no improvement.
[17:37:10] <K6MLE> Brand new power supply prividing ample current.

[17:38:06] <archivist> have you set the current on your drivers
[17:38:44] <K6MLE> Yes, the current has been set according to the G540 manual ... I'm using a 2.7K resistor on the DB9.
[17:38:49] <archivist> set a slower acceleration till it works
[17:39:26] <archivist> and check you wired the motor correctly
[17:39:48] <ssi> heh I'm printing some cable chain, and I actually like the printed chain better than the igus opentop chain I have
[17:40:23] <K6MLE> I'll play with the acceleration, but I should mention that the stalls, when running gcode, mostly occur when making arcs, as opposed to a XY traverse.
[17:41:00] <K6MLE> I am confident with the way the motors are wired.
[17:41:04] <archivist> check stiffness of machine too
[17:41:20] <gene78> partitioner looks broken, it only allows a 1 meg boot/grub! wtf?
[17:41:21] <archivist> are they stalling at the top speed
[17:42:00] <K6MLE> Just swapped out old motors (unipolar) and an old drive, for newer bipolar motors and the G540.
[17:42:17] <kfoltman> Loetmichel: could be worse, endmills in your pocket in the airport ;)
[17:42:22] <K6MLE> Machine stiffness didn't appear to be an issue before.
[17:42:37] <archivist> K6MLE, top end speed may be lower
[17:42:43] <Loetmichel> kfoltman: the endmills are in the jackets pocket
[17:42:57] <Loetmichel> ... and the leatherman wave at the belt ;-)
[17:43:06] <K6MLE> I don't notice a specific stalling at top speed when making a traverse movement ...
[17:43:19] <K6MLE> Reduce the top end speed?
[17:43:31] <archivist> yes
[17:43:33] <kfoltman> Loetmichel: I was thinking of a machine gun ammo-looking endmill 'clip' ;)
[17:43:37] <K6MLE> Okay
[17:43:44] <archivist> torque drops with speed
[17:44:06] <kfoltman> Loetmichel: or a vanity CNC 'tool picker' ;)
[17:44:08] <ssi> K6MLE: if it's stalling in arcs rather than rapids, it may be accel
[17:44:38] <K6MLE> The location of the new machine means it's not currently on the network, so I'll check it and come back here.
[17:45:05] <K6MLE> ssi: as in accel to high?
[17:45:11] <ssi> yeah
[17:45:26] <ssi> I'd turn accel and velocity way down and work upwards
[17:45:50] <K6MLE> Okay, so I have two things to try ... accel and velocity ... will give them a try and report back ... thanks!
[17:46:24] <archivist> K6MLE, if you are running through a resonance it will get noisy and possibly stall

[17:46:59] <Loetmichel> kfoltman: nothing that fancy, jkust a few of these packets:
http://www.cyrom.org/palbum/main.php?g2_itemId=13000
[17:46:59] <K6MLE> I was hoping the resonance issues would have been solved by putting the motors under the load of the machine ...
[17:47:05] <archivist> arcs are a "good" way of finding that problem
[17:47:57] <ssi> K6MLE: what drives are you using
[17:48:27] <kfoltman> Loetmichel: BTW, just ordered some 45 degree v-bits, going to try your method of enclosure-making (possibly using ABS or thick HIPS as a material)
[17:48:41] <kfoltman> Loetmichel: and put way more screws in the gantry :D
[17:48:48] <Loetmichel> hrhr
[17:49:15] <archivist> ssi, G540
[17:49:17] <kfoltman> if I push on the Z axis, the whole gantry moves, so that's definitely not good
[17:49:24] <kfoltman> might be the source of backlash indeed
[17:49:31] <Loetmichel> i "lost" about 1000 spax screws 5mm by 50mm in this:
http://www.cyrom.org/palbum/main.php?g2_itemId=4935
[17:49:48] <kfoltman> well, you needed the rigidity for that area
[17:50:52] <archivist> the extra screw are for DTI magnetic bases to stick to :)
[17:52:14] <Loetmichel> no, to hold the base and the gantry stiff
[17:52:31] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=4053 <- thats inside the base
[17:53:31] <kfoltman> K6MLE: if it stalls when moving diagonally but no in X only or Y only then it may be a power supply (guess how I knew :>)

[17:55:13] <Flipp> anyone have a suggestion for a smallish miter saw that'd fit in an apartment?
[17:55:15] <k6mle-CNC> Should I make the velocity and accel adjustments in the INI file at [TRAJ}?
[17:56:20] <kfoltman> I never had accel problems with arcs that wouldn't be reproducible with rapids

[17:57:15] <k6mle-CNC> Perhaps the problem is not with accell then?
[17:57:36] <kfoltman> k6mle: what happens if you reduce the drive current for the steppers?
[17:57:45] <kfoltman> k6mle: does it also stall when running all 3 axes at the same time?
[17:57:50] <kfoltman> preferably at top speed
[17:57:58] <Loetmichel> kfoltman: s/accel/resonance and i can tell the nicest stories ;-)
[17:58:12] <kfoltman> Loetmichel: resonance seems evil indeed
[17:58:14] <k6mle-CNC> Not sure how I'd make that adjustment on the G540?
[17:58:25] <ssi> the resistor on the connector

[17:59:36] <kfoltman> k6mle: is your power supply adequate? is your wiring adequate?
[17:59:45] <kfoltman> any risk of ground loops?
[17:59:59] <ssi> what voltage
[18:00:12] <kfoltman> also, mechanical problems can easily cause missed steps
[18:00:21] <k6mle-CNC> I think the supply (bought for this purpose) is more than adequate ... it's got plenty of headroom ...
[18:00:35] <kfoltman> what voltage/current?
[18:00:40] amnesic is now known as amnesic_away
[18:00:57] <k6mle-CNC> As for mechanical problems ... the machine was working fine with the old motors and controller ... just needed to upgrade it.
[18:01:36] <k6mle-CNC> Power supply current is 8 A and the voltage is set to 45 volts at present.
[18:01:58] <IchGuckLive> thats ok for 3 Axis
[18:02:01] <kfoltman> 2.7A per phase to 3 motors?
[18:02:15] <gene78> install done in AHCI mode, no boot disk found on the reboot.....
[18:02:20] <k6mle-CNC> kfoltman: that's correct.
[18:02:23] <archivist> bigger motors often are slower so expect to change acceleration and max speed
[18:02:48] <kfoltman> k6mle: 4-wire or 8-wire motors?
[18:02:55] <k6mle-CNC> 4-wire
[18:03:20] <kfoltman> yeah, I'd start with reducing the max velocity and the acceleration
[18:04:24] <k6mle-CNC> Right now the INI file has MAX_LINEAR_VELOCITY = 0.78, MAX_ACCELERATION = 1.5.
[18:04:57] <k6mle-CNC> That's in the [TRAJ] section.
[18:06:05] <kfoltman> k6mle: just try halving both and see what happens, just to see
[18:06:30] <k6mle-CNC> Okay ... will cut them both in half ..
[18:07:30] <kfoltman> what mode did the old driver work in? what kind of microstepping?
[18:08:23] <k6mle-CNC> kfoltman: that's a good question ... it's an old drive that came with the MAXNC10, with unipolar motors.
[18:08:41] <kfoltman> did it use microstepping? 2x, 4x, 8x, 16x?
[18:09:03] <IchGuckLive> kfoltman: its fixed on 16x
[18:09:09] <kfoltman> IchGuckLive: I mean the old one
[18:09:23] <kfoltman> before he replaced it with gecko
[18:09:27] <anarchos> any reason why i shouldn't use a 25 foot parallel cable? my choices are 3 feet, which is too short, or 25 feet (everything else is sold out)
[18:09:32] <IchGuckLive> oh are there more versions I LOVE Europ no Gecko inside

[18:26:30] <ssi> what's the lowest practical speed on it?
[18:26:41] <Loetmichel> and the second one on the chinese 6040 cnc at the company is also
[18:27:04] <Loetmichel> ... which now, after about 2 jears, starts to "sing" with the bearings when cold

[19:06:57] <_methods> what are you using now for tool
[19:07:04] <jdh> I imagine an onsrud up-cut cutter would help a lot.
[19:07:07] * JT-Shop cuts a 1 1/2" deep slot in 1018 with a 3" long 7/16" hss end mill... I hope I make it
[19:07:36] <jdh> first attempt was a 2-flute 1/8" carbide because it was there
[19:07:47] <_methods> yeah 2 fluter should work
[19:07:50] <jdh> I have some single flutes too but I have snapped a few of those
[19:07:56] <_methods> single flute would be better
[19:08:41] <_methods> well if you're not using coolant at least use airblast
[19:08:44] <_methods> that will help
[19:09:18] <jdh> first cut with this machine was last night. I was holding the vacuum cleaner hose.
[19:10:22] <jdh> I have other things to do to it first though. having to remember to turn the spindle on is amazingly hard.

[19:45:34] <kfoltman> it's clearly a mechanical problem, pressing on the fixed bearing block side helps
[19:46:41] <seltecc> how can I switch directions of arrow keys in the hal file?
[19:46:53] <Loetmichel> thats a bearing block not gliding but "rubbing"

[19:47:32] <Loetmichel> hmmm
[19:47:42] <kfoltman> the offending one is the ballscrew floating side
[19:47:45] <Loetmichel> maybe you got dirt in one of the bearing blocks
[19:47:50] <kfoltman> could well be
[19:47:59] <Loetmichel> that sounds ecacly like sliding balls instead of moving balls

[21:15:18] <archivist> k6mle-CNC, I found a break out board had a resistor for the driver opto as well as the driver having one so the signal was not getting into the drive properly, one needs to scope the signals to check
[21:16:55] <k6mle-CNC> archivist: assuming the drive isn't the problem, it would seem there's an adjustment that should be made in either HAL, or INI files?
[21:17:06] <gene78> 10.04.4 linuxcnc install probs, no ipv4 static network, what file contains the ipv4 disable command?
[21:17:19] <archivist> this is an electronic not software
[21:17:29] <archivist> problem
[21:17:58] <k6mle-CNC> so it could be the parallel port giving me some grief?
[21:18:30] <archivist> is the port direct to the driver or via some breakout
[21:18:43] <k6mle-CNC> I have no breakout ...
[21:19:38] <k6mle-CNC> I'm pretty sure I set the BIOS for EPP on the parallel port ...
[21:20:09] <archivist> I would be scoping the signal on the dir pin
[21:20:40] <k6mle-CNC> Okay ... I'll create something that will allow me to do that ...
[21:21:34] <archivist> also some have needed to change the delay dir signal change to step time which is in the ini somewhere
[21:22:01] <JT-Shop> Tom_itx, seemed to be

[21:23:23] <archivist> CaptHindsight, no, too specialised for me
[21:24:44] <CaptHindsight> archivist: some of these are amazing, the gears in that pic have 250K miles on them
[21:25:17] <archivist> nice even wear
[21:25:56] <archivist> unlike the typical 150 year old clock pinion
[21:26:19] <CaptHindsight> the only reason it's apart is the pinion seal has started leaking after 20 years
[21:26:41] <k6mle-CNC> archivist: the HAL file shows dirhold and dirsetup both at 6500 ... does that seem reasonable for G540?
[21:26:47] <CaptHindsight> what happens in old clock gears? How do they wear?
[21:27:05] <archivist> CaptHindsight, a bit of wear

[23:25:18] <ssi> CaptHindsight: what's the difference? the step/dir mode?
[23:26:14] zz_prtksxna is now known as prtksxna
[23:27:34] <CaptHindsight> one is mostly just an amplifier, the controller version has some PLC functionality

[23:28:31] <ssi> yea I saw it
[23:28:42] <ssi> those drives are very nice
[23:28:49] <ssi> the regeneration bus is clever
[23:29:21] <CaptHindsight> a bargain over the new junk even at $300 used
[23:29:25] <ssi> yep
[23:29:50] <ssi> especially when you consider I paid $90 apiece for leadshine stepper drives
[23:29:58] <ssi> $110 for these geminis is a bargain
