[02:35:29] <spack> so how would one go about moving a 4000 mill about 500 miles?
[02:35:43] <spack> let's say i rented a flatbed... how do i ever get it on/off of it? :S
[02:35:45] <Tom_itx> call an equipment mover
[02:35:53] <spack> i'm assuming that will cost too much
[02:36:06] <Tom_itx> Belger Cartage service is one
[02:36:24] <Tom_itx> likely rather costly yes
[02:36:58] <Tom_itx> rent a crane to get it off
[02:37:26] <Tom_itx> companies rent such things
[02:37:27] <cradek> spack: use uship.com to find a semi driver with an appropriate trailer. rent or borrow a forklift at both ends.
[02:37:47] <spack> hmm
[02:37:52] <Tom_itx> might be too heavy or cumbersome for a forklift
[02:37:58] <cradek> you'll be done for < $1k
[02:38:05] <Tom_itx> might just tip the forklift
[02:38:06] <spack> depends if it's palletized or not
[02:38:07] <cradek> nah only 2 tons, no problem
[02:38:11] <Tom_itx> k
[02:38:16] <spack> there are some giant forklifts out there
[02:38:28] <cradek> sure you have to get appropriate forklifts :-)
[02:38:32] <spack> :)
[02:38:43] <Tom_itx> there are moving rollers as well to get it out the door
[02:39:11] <spack> i plan on egyptian-ing it
[02:39:14] <spack> with pipes
[02:39:24] <spack> but if i have a forklift, might as well use that
[02:39:30] <Tom_itx> that works just as well
[02:39:43] <Tom_itx> * nearly as well
[02:39:58] <spack> will finding a guy on uship be cheaper than renting a flatbed?
[02:40:01] <cradek> I think mine weighs about twice that and I didn't have any trouble renting a forklift
[02:40:16] -!- sumpfralle has quit [Ping timeout: 256 seconds]
[02:40:38] <cradek> spack: renting a flatbed PLUS 1000 miles worth of fuel
[02:40:49] <spack> well i was including that
[02:40:50] <cradek> remember you drive both ways, he drives one way
[02:41:27] <spack> yeah, i guess it only cost $800 to have a car shipped coast to coast
[02:41:31] <spack> but he had like 5 other cars on there
[02:41:52] <spack> those tend to be a lot easier to get on and off too :)
[02:41:53] <cradek> a smart truck driver will load his truck appropriately and won't cross the country without carrying something useful
[02:41:57] <spack> weigh about the same...
[02:42:07] <cradek> on uship they bid for your business, so they are smart those ways
[02:42:17] <spack> i'll check it out
[02:42:43] <cradek> I'd do it again that way in a heartbeat (although mine was way too big to pull with my truck)
[02:43:02] <Tom_itx> maybe he can leave his flatbed so you're not paying him to stand around
[02:43:16] <cradek> 2T you can probably do with a regular truck, but I bet you'll pay $500+ for JUST the fuel
[02:43:28] <skunkworks> the driver slid the acroloc off the back of his flatbed.
[02:43:58] <Tom_itx> or borrow JT-Shop's frontloader and flatbed :D
[02:44:06] <skunkworks> dad was impressed - the guy unhooked the cable and dad was wondering... but slid off as slick as snot.
[02:44:37] <spack> looks like a forklift is $300-$400/day
[02:44:43] <spack> times 2
[02:45:04] <cradek> around here you usually rent them by the hour?
[02:45:24] <spack> hmm
[02:45:32] <spack> this site has them by day, week, and 4 week
[02:46:55] <spack> i'll check CL

[03:08:10] <cradek> http://www.linuxcnc.org/docs/html/man/man9/hm2_7i43.9.html
[03:10:47] <nspielb> im confused how to know whether it is 200k or 400k
[03:11:23] <cradek> 09:32 < pcw_home> 7I43-2 is 200K 7I43-4 is 400K
[03:11:31] <cradek> you asked that question earlier
[03:12:52] <nspielb> yeah and he said on the board it should say 200k or 400k and i cant find where it says it on the board
[03:18:01] <nspielb> they put yellow paint over the xlinx chips
[03:22:58] <KimK_3> nspielb: Yellow=4, if that means anything. Do they put red (=2) paint over some of them?
[03:23:26] <nspielb> nope. its actually a 2
[03:23:37] <nspielb> i googled the xlinx number and it said 200k in the datasheet
[03:23:44] <KimK_3> Ah, how did you figure it out?
[03:24:00] <KimK_3> So you got the paint off?
[03:24:08] <nspielb> a little bit yes
[03:24:11] <nspielb> the top line
[03:24:45] <KimK_3> Great, congrats!

[07:33:23] <kengu> JessicaRN: what are you planning on doing with it and what size is it. we have one small "engraver" eg. ~30W co2 that we use to cut some acryl (3mm) or engrave wood. it takes hpgl-commands direct from lpt port, and with our print server acts as a printer.
[07:34:13] <kengu> then we have the bigger one 140cm*90cm or so working area and some 70W. that we converted to linuxcnc as the hpgl approach is not so good
[07:34:56] -!- abetusk has quit [Ping timeout: 256 seconds]
[07:35:13] <JessicaRN> this has the Moshi USB controller, I guess that card is rather proprietary
[07:35:36] <JessicaRN> the device has a 40w co2
[07:35:54] <JessicaRN> and a bed of about a sheet of letter sized paper
[07:39:27] <kengu> so it is not acting as serial or parallel anything the usb thingy
[07:40:18] <kengu> in that case I would go the linuxcnc way
[07:40:23] <JessicaRN> I haven't installed the original sw yet.

[07:46:03] <JessicaRN> cool
[07:47:39] <JessicaRN> I'll check out those links. Chat again in a day or so. thx for the help.
[07:47:44] <kengu> I have heard of those plugins where you just say "cut" or "engrave" from corel after tweaking some parameters for the work and it just works. We are pretty happy with print functionality as we can just say "print" and it will then run the laser. It is not the same

[08:40:03] <aksr> hi archivist :)
[08:40:19] <archivist> ello
[08:40:21] -!- rob_h [rob_h!~rob_h@] has joined #linuxcnc
[08:40:30] <archivist> is it apart now
[08:40:43] <aksr> yes,..
[08:41:07] <aksr> i found out what is wrong with a power shaft
[08:41:56] <aksr> do you see central (biggest) gear here, for example http://www.lathes.co.uk/volman/img15.gif?
[08:42:32] <archivist> worm gear
[08:42:37] <aksr> its shaft is bend
[08:43:12] <aksr> my camera still isn't here, or else i'll show it to you
[08:43:34] <archivist> either make new shaft or bend it straight
[08:43:39] <aksr> also, that taper pin, it had three pieces
[08:43:49] <aksr> _not_ line up
[08:43:57] <aksr> so i had to drill throught it
[08:44:04] <archivist> already sheared
[08:44:10] <aksr> everything went fine, i'm happy in this respect
[08:44:47] <aksr> i'm not sure how elegant is to make it straiht, i was thinking to make a new one
[08:45:00] <aksr> *straight
[08:45:48] <aksr> so, after the taper pin problem, i have problem with worm gear(?) shaft
[08:46:10] <aksr> atm, my problem is, i don't know (meaning i'm not 100% sure) how to remove
[08:46:11] <aksr> it
[08:46:50] <archivist> could be a press fit
[08:47:17] <archivist> or look for another taper pin
[08:47:36] <aksr> let me (try to) explain it:
[08:49:45] <archivist> note that shaft may be driving gears in the front part of the carriage
[08:50:03] <aksr> i has double-gear mechanism (one smaller, one bigger), it has multiple screws throught it; it has similar double-gear on the other side, and its small one fits with small one of first mentioned double gear
[08:50:59] <aksr> now, i'm not sure how to remove it, from one side it has bearing which i could remove, because shaft is twisted and bend (not very good material?)
[08:51:13] <aksr> *i couldn't remove
[08:51:25] <archivist> removing screws should allow it all to come to bits, may be another fight to undo the screws though
[08:51:57] <aksr> i don't have access to the screws
[08:52:06] <aksr> i mean i don't have enough spacde
[08:52:08] <aksr> *space
[08:52:29] <archivist> must be space else one could not assemble
[08:52:32] <aksr> i was thinking: it's made to be removed..
[08:52:45] <aksr> i was thinking the same thing

[08:53:11] <archivist> although some work requires special tools
[08:53:27] <archivist> make the tools you need
[08:54:10] <aksr> ..,if i punch it from other side (which isn't bent), it goes until double-gear-thing comes to the wall of the apron
[08:54:35] <aksr> archivist: can you picture anything what i'm telling you? :)
[08:55:05] <archivist> what holds the gear on
[08:55:11] <aksr> i was punching it with a hammer and wood
[08:55:25] <aksr> that's my main question!, i'm not sure
[08:56:02] <aksr> maybe those screws are for smaller gear to fit with larger one...
[08:56:04] <archivist> I cannot know, pictures, bright light and look inside
[08:56:06] <aksr> ..not sure ..
[08:56:43] <aksr> archivist: i was looking for hours, i don't have _courage_ to try to punch it,..
[08:56:46] <archivist> or find the manual and exploded diagram
[08:56:51] <aksr> i feared i may broke something

[08:58:37] <archivist> I keep manuals and scan for people but dont have many lathe manuals
[08:58:39] <aksr> also, conundrum for me is, how that shaft got first twisted then bend ..
[08:59:11] <aksr> the man which sold me the lathe, gave me whole set of tools with it
[08:59:18] <aksr> but manual, he didn't have
[08:59:27] <archivist> user may be able to select two drive methods at once and therefore jam the mech
[08:59:49] <aksr> two drive methods?
[08:59:50] <archivist> or just drove it to the end
[09:00:22] <aksr> it isn't driven to the end-that i'm sure
[09:00:32] <archivist> longitude feed and screw cutting
[09:00:57] <aksr> screw cutting?
[09:00:59] <archivist> there should be an interlock
[09:01:09] <aksr> you mean power shaft and leadscrew?
[09:01:23] <aksr> or longitude and perpendicular..
[09:01:39] <archivist> fine feed is separate from screw cutting feed
[09:02:36] <aksr> my lathe has two shafts: leadscrew (for screw cutting) and (i think it's called cross..) power shaft
[09:02:39] <archivist> on my southbend it is one shaft with a slot for fine feed and thread for screw cutting
[09:02:57] <aksr> it's separate on mine
[09:03:14] <archivist> should be impossible to engage both at the same time
[09:03:27] <aksr> could it be that two directions bent it, like: →↑
[09:03:41] <aksr> archivist: it's impossible to engage both at the same time
[09:03:48] <aksr> but this was possible: → ↑
[09:03:54] <aksr> or ← ↑
[09:04:14] <archivist> walking away while self acting would be a cause though
[09:04:16] <aksr> could it be that this(→↑) bent it?
[09:05:05] <aksr> it's possible to go longitude and perpendicular at the same time
[09:05:20] <aksr> i'm not sure is it permitted
[09:06:26] <aksr> i always wanted to have/use/ lathe, but this, this discouraged me..
[09:06:35] <aksr> one thing i'm sure of, i didn't do this
[09:06:46] <aksr> i think it came with this problem
[09:06:47] <aksr> ..
[09:06:52] <aksr> not sure, though. .
[09:09:33] <archivist> restoring old stuff can be fun
[09:09:59] <aksr> it can, if you have enough resorses (and it's possible to do it)

[09:16:05] <aksr> what can you do, you played you part honestly ..
[09:16:14] <archivist> found out some years later talking to the man who did it
[09:16:50] <aksr> was it expensive/hard?'
[09:17:30] <aksr> i'm waiting now

[09:21:36] <Valen> I also read things like the FTTP connection is stalled as its in a MDU

[09:36:05] <aksr> how good?
[09:36:10] <archivist> not ideal though
[09:36:45] <archivist> as good as your setups can be
[09:37:05] <aksr> i was thinking to buy a mill sometime in the future
[09:37:22] <archivist> Valen, the uot going rate went from 400k to 1 mb after a fix
[09:37:25] <archivist> out
[09:38:26] <aksr> archivist: there are some chinese lathes which have extended capabilities for milling ..
[09:38:32] <archivist> it is better to get a separate mill
[09:38:49] <aksr> as for (almost) all things in the world :)

[14:51:58] <JT-Shop> tjb1: thanks
[14:52:11] <JT-Shop> did you try it out?
[14:52:23] <nspiel_> i think so. becuase i didnt connect my motor drivers yet and it would not let me do the motor test. none of the config options were highlighted
[14:52:52] <nspiel_> i mean axis configuration didnt work when i didnt connect the motor drivers to the 7i43
[14:53:03] <pcw_home> some parts of pncconf need the hardware there
[14:53:24] <jdh> I only used it once. The motor test part didn't work as I recall.
[14:54:08] <pcw_home> I think the open loop test works now (and needs the hardware of course)
[14:54:16] <jdh> or maybe it was the test worked, but you couldn't continue pncconf after testing.
[14:54:16] <nspiel_> pcw_home am i correct in assuming axis configuration would not work because the drivers were not connected?
[14:54:46] <nspiel_> I was trying to do the open loop test and none of the buttons were clickable but I didn't have the motor drivers connected
[14:54:56] <pcw_home> No, besides for initial hardware checkout, I would no use pncconf

[14:55:30] <pcw_home> i would just try launching one of the sample configs
[14:56:05] <pcw_home> (to see if the 7I43 is found and configured)
[14:56:18] <nspiel_> do i need to upload firmwire to the 7i43 before trying to use pncconf?

[15:02:07] <nspiel_> yep they did.
[15:04:01] <nspiel_> so do I need to upload firmwire to the 7i43 to use it like you said in the configuration form the menuy
[15:04:37] <jdh> how does one upload the firmware other than starting linuxcnc?
[15:05:03] <jdh> and for a 7i43 is there any way for linuxcnc to recover after power cycling the 7i43?
[15:05:10] <pcw_home> Its done in the hal file
[15:05:33] <pcw_home> loaded every time linuxcnc launches
[15:05:34] <nspiel_> or you can do it from cmd
[15:06:17] <nspiel_> so when the firmwire gets uploaded, is that when a .pin file is made? I couldn't find it last night
[15:06:57] <pcw_home> Pin files are made either by reading the IDROM of an live config or at bitfile compile time
[15:07:28] <pcw_home> you can always get the pinout from the dmesg )kernel log)
[15:07:48] <nspiel_> is that the pinout of the parallel port or for the 7i43
[15:08:13] <pcw_home> its is the pinout of a particular 7I43 configuration

[15:12:04] <nspiel_> do you access that through cmd? What command do you type? Is it once you have set your config up in lcnc?
[15:12:46] <pcw_home> just type dmesg in a terminal window
[15:14:09] <nspiel_> after lcnc is open with 7i43 config setup?
[15:16:03] <pcw_home> well maybe

[15:35:38] <jthornton> well I test the estop first if you must know
[15:36:10] <nspiel_> i see that there are limit switch outputs on one the p3 connectors. What is the correct way of wiring up the switches?

[15:40:57] <nspiel_> i have 7i43 hooked up to two 7i25s
[15:41:29] <jdh> I'd suggest another daughterboard for the other port

[15:41:49] <nspiel_> in order to get limit switches?
[15:42:14] -!- jfire has quit [Quit: Leaving.]
[15:42:16] <jdh> you could connect them directly, but you will probably be happier if you don't
[15:42:17] <nspiel_> cant you just configure the pins of the other port p3 and then pull them with a 50 pin cable to limits switches and estops etc
[15:42:45] <jdh> you can.
[15:44:58] <nspiel_> so when you connect them directly, I see there is one pin designated for each on the i/o but each switch etc has two pins. Where does the other pin go? to gnd?
[15:45:03] -!- syyl_ws [syyl_ws!~sg@p4FD12C56.dip0.t-ipconnect.de] has joined #linuxcnc
[15:46:09] <jdh> gnd or +V, depending on how you have the switches wired
[15:46:34] <jdh> add a pullup to +v, then have the switch to grnd.
[15:48:04] <jdh> I would suggest a 7i37 variant though.

[17:23:27] <NickParker> does mesa sell just a screw terminal breakout board?
[17:23:42] -!- md-2 has quit [Remote host closed the connection]
[17:24:09] <NickParker> No fancy drivers or anything, just a simple board to help connect wires to the parallel port?
[17:24:36] <NickParker> oh, 7i42 looks about right
[17:25:00] <NickParker> er, maybe not that isn't parallel is it
[17:26:18] <IchGuckLive> why not go with a simple C10
[17:26:29] <IchGuckLive> no mesa mesa is not parport
[17:26:56] <IchGuckLive> mesa is well beond parport
[17:27:13] <NickParker> i thought the backs of them were, but then they had more pins on the inside as well?
[17:27:33] <IchGuckLive> that is what it stands for
[17:27:52] <IchGuckLive> more powerr and control to your mill
[17:28:07] <IchGuckLive> you can do 2 C10 at once
[17:28:33] <IchGuckLive> but its better to go for a own BOB at more inputs
[17:28:46] <IchGuckLive> most are 12/5
[17:28:52] <IchGuckLive> so 12 pot 5 in
[17:28:58] <IchGuckLive> out
[17:29:35] <IchGuckLive> and linuxcnc supports also the parport config for in to the 8 data ports
[17:29:50] <IchGuckLive> so its 4/13
[17:29:57] <IchGuckLive> 4 out 13 in
[17:30:25] <IchGuckLive> but there is no BOB ready as iv seen for this
[17:30:38] <IchGuckLive> to go via the opo electronics
[17:32:36] <NickParker> wait i'm a bit confused, does the 6i25 have 2 parports on the back of it, or 1 parport on the back and then the square of pins on the face of it is the 2nd connector?
[17:32:51] <IchGuckLive> i use 24V over relay finder type to get the 13 inputs controlled from large mashines
[17:33:26] <NickParker> ok found a pic. looks like one parport and then the square thing on the card
[17:33:28] <IchGuckLive> NickParker: this are internal connectors of mesa 50 pin
[17:34:02] <pcw_home> The 5I25/6I25s are just like dual port parallel cards, they have a DB25 on the back braket
[17:34:04] <pcw_home> and a 26 pin header that can connect to another DB25+ bracket
[17:34:24] <NickParker> ah ok
[17:34:44] <pcw_home> so they can be used with standard parallel port breakouts/Gecko G540s etc
[17:35:41] <Lathe_newbie> pcw_home: but they are much faster?
[17:36:40] <pcw_home> for step generation or encoder counting sure
[17:36:57] <pcw_home> also for I/O expansion capabilities
[17:37:10] <Lathe_newbie> so there is closed loop possible, with the 6i25?
[17:37:20] <pcw_home> sure
[17:37:43] <andypugh> A maxed out 6u25 can have something like 1900 IO lines
[17:37:55] <NickParker> wow lol
[17:37:58] <andypugh> (Ah, no, it's about half that)
[17:38:03] <NickParker> still..
[17:38:08] <Lathe_newbie> pcw_home: what do i need for closed loop with dc servos?
[17:38:32] <andypugh> Lathe_newbie: Servo drives
[17:38:55] <Lathe_newbie> andypugh: but they dont need have connected the encoders?
[17:38:57] <Lathe_newbie> right?
[17:39:07] -!- chillly has quit [Quit: Leaving]
[17:39:39] <andypugh> It depends on the drives, and where the loop is closed. But typically with LinuxCNC you do want to take the encoders to LinuxCNC rather than just to the drive.
[17:40:11] <Lathe_newbie> so the drive needs just to be a power amp?
[17:40:37] <pcw_home> basically yes, a bare HBridge will do
[17:40:56] <Lathe_newbie> which can run with pwm+dir?
[17:41:04] <pcw_home> Yes
[17:41:06] <Lathe_newbie> and a current limitter?
[17:41:17] <andypugh> Yes. If you have a simple analogue-control power amp drive then you can (in theory) do it all with the bare parallel port. Extra hardware just makes the result better.
[17:41:31] -!- tmcw has quit [Remote host closed the connection]
[17:41:43] <Lathe_newbie> so 6i25 + H bridge is all i need?
[17:41:48] <pcw_home> Most retrofits use velocity mode drives (which close the velocity loop at the drive)
[17:43:12] <andypugh> Lathe_newbie: The common setup for servos is the 6i25 plus a 7i77 daughter board that adds a lot more IO and a seto of +/-10V drivers for common commercial servo amps.
[17:43:12] <pcw_home> For HBridges or current mode drives I recommend getting a PC that can runs a 2-4 KHz servo thread
[17:44:05] <andypugh> But in theory you could use the PWM direct from the back of a 6i25 to control your own H-bridge.
[17:45:31] <kwallace2> I would consider it a little more than theory.
[17:46:07] <pcw_home> Lots of people like the AMC drives for DC and brushless motors
[17:46:30] <andypugh> Well, yes. I have actually run a 3-phase brushless servo with PWM generated by an Arduino.
[17:46:46] <andypugh> I should have said "In principle" maybe.
[17:47:18] <andypugh> In practice you would want isolation and gate-drivers.
[17:47:47] <pcw_home> and with BLDC you could do this with just a parallel port (a bit crunchy perhaps but functional)
[17:49:24] <kwallace2> It's just that my HNC uses PWM amps with brushed motors very well. Why spend money on motor drivers, rather than amps, that just duplicate what could be done better in LinuxCNC?
[17:49:42] <andypugh> That would be a fun demo with that washing machine motor.
[17:50:25] <NickParker> ok well i think i need to scope on my mill some more
[17:50:33] <pcw_home> Funny, I was just thinking about that motor run that way
[17:50:36] <NickParker> and figure out how the spindle and toolchanger are software controlled
[17:51:16] <NickParker> before i order, because the 6i25 won't do me much good before i have everything set up anyway. I don't trust the bandit to not hurt itself if i try to run spindle on bandit and axises on linuxcnc
[17:51:23] <andypugh> pcw_home: The current project is running that motor on a 7i80, 7i76 and 8i20...
[17:51:45] <pcw_home> The 7I80 support needs work :-(
[17:52:19] <andypugh> That is what makes it a project.
[17:52:23] <pcw_home> I also have some firmware work to do to support 2 packet mode
[17:52:30] <andypugh> Though really I should be doing the tooltable stuff
[17:53:03] <andypugh> I wonder how well some 100W 100V servo motors would run on a 7i39HV?
[17:53:07] <pcw_home> Tool table work would benefit more people
[17:53:07] <NickParker> what's linuxcnc written in?
[17:53:13] * NickParker only knows python and arduino

[17:56:39] <NickParker> kwallace2: right, you've done this before lol. what breakout board did you use?
[17:56:46] <pcw_home> I wonder if theres some commonality between absolute encoder types that can be exploited
[17:57:37] <pcw_home> (I have FanucAbs,SSI working and soon BISS)
[17:58:09] <kwallace2> So far, I use a breadboard because each I/O seems to need different conditioning.
[17:58:30] <andypugh> I half think that an absolute encoder or resolver on seeing index-enable asserted should just instantly reset index-enable and zero itself apart from partial turns.
[17:59:14] <pcw_home> The Fanuc ones effectively always have index enable asserted
[17:59:45] <andypugh> The previous resolver code watched for the top bit flipping. Which happens twice a cycle, and in different positions in different directions. I am not safe to be let loose with a compiler really.
[18:00:15] <NickParker> Oh i see that on your site. how did you connect parport to breadboards? I see you have one with a ton of blue wires coming out of it, have a link for that?
[18:01:16] <pcw_home> Thats pretty much the issue that the hardware stepgen deals with to know when to generate a pulse

[18:03:13] <kwallace2> NickParker: In that picture, I used a DB25 with solder cups and CAT5 cable. Winford has a better setup, but a breadboard is not my first choice for a long term solution.
[18:03:20] <andypugh> I need to be a bit cleverer with the multi-pole resolver code.
[18:04:13] <NickParker> kwallace2: have you got a first choice or are you just saying a breadboard definitely isn't it?
[18:04:53] <pcw_home> if you have multiple indexes you could count but the count is volatile (unless you have a mask from a optoflag or some such)
[18:04:53] <andypugh> Custom PCB? They only cost $20. Or $10 if two of you want one.
[18:05:56] <andypugh> Yes, I have assumed that you don't mind a wandering index if you are tapping or threading. And the docs say it isn't intended for homing.
[18:06:02] <pcw_home> This has come with the idea of simulated index (mod encoder count)
[18:06:47] <kwallace2> It's too easy to bump the breadboard and loose a connection. Once the design is worked out, I would think a custom PCB would be better, but my breadboard has been in place for a long time.
[18:06:49] <NickParker> if i want a custom pcb would i have to draw it up properly in eagle or something similar?
[18:06:50] <andypugh> For a single-track encoder I actually prefer missing-pulse indexing.
[18:07:04] <andypugh> NickParker: Yes, but then that is almost fun.
[18:07:35] <andypugh> I occasionally design PCBs just for the hell of it :-)
[18:07:43] <kwallace2> http://www.winfordeng.com/products/cat_pbc.php
[18:08:02] <pcw_home> works fine as long as you realize you cannot exit linuxCNC and restart a threading cycle
[18:08:04] <pcw_home> (thinking where encoder is not geared 1-1 with spindle)
[18:10:32] <pcw_home> The Fanuc "absolute encoders" are interesting in that they have a absolute commutation track (4 cycles for a 8 pole motor)
[18:10:45] <NickParker> ok well i have to run for a dentist appointment, but I think I'll buy my 6i25 and some parport to breadboard adaptors later today, get the whole thing running on breadboard then do a custom pcb.
[18:11:09] <NickParker> imagining up the whole design is a bit much for me without having something already built.
[18:11:09] <andypugh> pcw_home: 4-bit gray-code, and "bldc" can interpret it.

[19:30:04] <cradek> offset X a bit so it doesn't cut, run your original program, and eyeball it
[19:30:16] <cradek> ooh yeah, internal sure makes it worse
[19:30:33] <rogge> cradek: eyeball, then rotate the part to get the index in the right spot?
[19:30:52] <cradek> nah, just tweak your Z offset
[19:31:01] <cradek> once you get it centered leave it alone :-)
[19:31:03] <jdh> or tweak the tool?

[19:31:29] <andypugh> Or spindle-overr-de, thinking about it
[19:31:30] <rogge> Anyway I can do the eyeballing while turning the spindle by hand?
[19:31:49] <cradek> well it might not cut in exactly the same place if you change the spindle speed
[19:31:59] <archivist> no you can play with where you start, also make sure you have room at end of cycle to test the thread for a rerun when it is wrong

[19:35:54] <cradek> rogge: catching a moving target is hard, and everything is a compromise, and that seemed like the least harmful sacrifice
[19:36:12] <andypugh> I think what I did was set the cycle going, then feed-over-ride it, then rotated the part in the chuck to get the thread aligned with the tool. (and jogging the tool to a radius where it engaged the thread)
[19:36:20] <archivist> after the index until the carriage is at following sped it is accelerating not geared
[19:37:10] <rogge> so the acceleration after the index would result in a different start position?
[19:37:21] <cradek> that's a good succinct explanation
[19:37:47] -!- vladimirek has quit [Remote host closed the connection]
[19:37:56] <rogge> since I only need a couple of thou, do you think I could just do it by driving the spindle with my hands?
[19:37:57] <archivist> a good guess considering you wrote it ?
[19:38:26] <cradek> rogge: sure, and if you keep your spindle slow, in practice it'll line up fine with your hand run
[19:38:57] <rogge> OK.... I'll give it a shot. Thanks!
[19:39:12] <archivist> rogge for previous manual lathe cockups like that I have hand held the threading tool to chase it out a bit to fit
[19:39:30] <skunkworks> rogge, ! nice lathe update!
[19:39:35] <andypugh> A thread chaser might be exactly the right tool for the job.
[19:39:39] <cradek> it's sure easier to do this on a manual lathe...
[19:39:45] <rogge> archivist: that sounds worth a try first. I'll whittle on it a while first
[19:40:18] <cradek> engage the nut, poke the tool into the thread, clamp the tool down

[19:44:05] <rogge> I have four, and I did 'em already. It looks like archivist's suggestion may work
[19:46:45] <archivist> my first and only cnc internal thread I got the tool well out the way for testing and re ran it till it fitted
[19:47:16] <skunkworks> archivist: wow... (multi axis sharpener... :) )
[19:48:17] <archivist> I keep thinking the grinder should be on the mill as another axis...naughty
[19:48:27] <andypugh> I have a lathe backplate to thread. That will be tricky to try the mating part in...
[19:48:55] <archivist> easy, mill the thread
[19:49:03] <skunkworks> andypugh, or buy another lathe....
[19:49:29] <tjb1> JT-Shop: did I try what out?
[19:49:32] <andypugh> I have another lathe.
[19:49:48] <skunkworks> heh
[19:49:56] <andypugh> I won't be cutting the thread on the lathe that the thread is for. (though I have done that)
[19:50:05] <skunkworks> take the spindle out of the one... and...
[19:50:18] <archivist> I think he is trying to not remove the spindle...lazy
[19:50:20] <andypugh> Thinking about it, I can just take the chuck off, then screw it back on for a tweak if needed.
[19:50:48] <andypugh> (that is, the chuck mounted to the lathe that is doing the threading)
[19:51:01] <archivist> but the register matters the thread can be a bit sloppy
