[02:03:19] <Jymmm> Maybe somebody could help me. I'm trying to align the mirror in my laser for all four corners of the table....
[02:04:06] <Jymmm> The beam coming fro the laser is not dead center, more SE
[02:04:59] <humble_sea_bass> what kind of adjustment rig
[02:05:36] <Jymmm> The mirror has three screw adjustments in an reverse "L" layout...
[02:06:05] <Jymmm> the TR screw the manual says is for up/down,
[02:06:17] <Jymmm> The BL screw is for LEFt/RIGHT
[02:06:39] <Jymmm> THE BR screw is the pivot point and says rarely needs to be adjusted.
[02:07:35] <Jymmm> Now, since the beam from the laser is SE insteadof center, I think I need to compensate witht he pivot a bit, but I'm not sure which way.
[02:09:24] <Jymmm> The beam comes from here, but as you see there it's centered
http://www.tux-lab.com/assets/gallery_image/11/small/M300_exit_lense.jpg?1299545961
[02:09:42] <Jymmm> On mine it's SE
[02:10:20] <humble_sea_bass> I assume you're gonna have to set something up like a focault test
[02:10:27] <Jymmm> http://www.inlay.com/cnc/laser/image2.jpg
[02:10:44] <Jymmm> See in the top left? thats where the beam comes from
[02:10:59] <Jymmm> the black box in front of it is where the mirror is
[02:11:24] -!- sudobangbang has quit [Ping timeout: 260 seconds]
[02:11:54] <Jymmm> humble_sea_bass: a what?
[02:13:46] <Jymmm> http://i60.tinypic.com/5nm8zn.jpg
[02:13:55] <Jymmm> thats the mirror and three screws
[02:15:47] <Jymmm> I realize I can just move to the four corners and note where the beam is, but I don't know how to figure out it's an axis adjustment or a pivot one
[02:16:55] -!- AR__ has quit [Ping timeout: 272 seconds]
[02:16:57] <Jymmm> If this is the four corners...
[02:17:04] <Jymmm> 1-----2
[02:17:05] <Jymmm> | |
[02:17:05] <Jymmm> 3-----4
[02:18:52] <humble_sea_bass> http://www.atm-workshop.com/foucault.html
[02:19:48] <humble_sea_bass> adjusting mirrors is a bitch withot a proper setup. and you're gonna have to trial and error it
[02:21:02] -!- likevinyl has quit [Quit: likevinyl]
[02:21:20] <Jymmm> I kinda get that, but I'm thinking there must be some way to determine if axis or pivot needs an adjustment based upon where the beam is landing on the forn corners
[02:21:22] <Jymmm> four*
[02:22:32] <humble_sea_bass> yeah geometry, your four screws create two axis which the mirror pivots
[02:22:42] <Jymmm> three screws
[02:23:34] <humble_sea_bass> same idea
[02:23:45] <Jymmm> it's like taking a sheet of paper and twisting it slightly so the four corners are not flat
[02:24:04] <Jymmm> 2D I get, the 3D aspects I don't
[02:24:08] -!- aniM has quit [Remote host closed the connection]
[02:24:46] <humble_sea_bass> well, any ol projector wou're normally gonna have soft corners
[02:25:28] <Jymmm> soft corner?
[02:26:26] <humble_sea_bass> the focus is best within a certain radius from the center
[02:26:59] <Jymmm> Ah, well not focusing, but alignment.
[02:27:06] <Jymmm> but yeah

[04:26:08] <CaptHindsight> LeelooMinai: most use the Ubuntu 10.04, some use 12.04 or Debian Wheezy, I haven't heard of any using 14.04 yet. I only got as far as installing the 3.4.55 RTAI kernel in 14.04
[04:26:36] <CaptHindsight> I haven't built Lnuxcnc on it yet
[04:26:46] <LeelooMinai> Right, I am trying to install 3.8 right now
[04:27:33] <LeelooMinai> the problem with those old Ubuntus kept popping out. For example, Intel stopped supporting 12.04 for GPU drivers
[04:27:37] <CaptHindsight> LeelooMinai: 3.8 kernel?
[04:27:46] <LeelooMinai> No, rtai
[04:28:09] <LeelooMinai> Or is it too high a version for linuxcnc?
[04:28:13] <CaptHindsight> using which RTAI branch?
[04:28:27] <LeelooMinai> I am trying to follow this:
http://hart.sourceforge.net/rtai/installation_14_04_64bit_woc.html
[04:28:59] <LeelooMinai> If it's bound to fail, tell me now:)
[04:29:20] <CaptHindsight> looking at the hart toolbox ....
[04:30:56] -!- jerryitt has quit [Quit: Connection closed for inactivity]
[04:32:01] <CaptHindsight> the volcano branch of RTAI used to work but it's been broken for months
[04:32:39] <CaptHindsight> the last stable branch of RTAI is ..... <drum roll>
[04:32:56] <LeelooMinai> 1.0? :/
[04:33:36] <CaptHindsight> https://github.com/ShabbyX/RTAI/tree/linuxcnc-old
[04:33:57] <XXCoder1> remmy guy who always asked about a lathe?
https://www.youtube.com/watch?v=yCaGW9z4blM lol
[04:35:11] <LeelooMinai> CaptHindsight: Does it have a version?
[04:35:41] <LeelooMinai> CaptHindsight: And is it 2 months old as in commits, or older?
[04:38:16] <LeelooMinai> Also if linuxcnc is not working with later RTAI, is this because there are changes in API and linuxcnc is not keeping up or other reasons?
[04:38:32] <XXCoder1> something related to rtoi something
[04:38:33] <XXCoder1> ?
[04:40:19] -!- valeech has quit [Ping timeout: 244 seconds]
[04:40:59] <CaptHindsight> the scheduler in RTAI is currently broken in anything newer than that branch ^^
[04:41:08] <CaptHindsight> LeelooMinai: ^^
[04:41:29] <XXCoder1> real time A? I?
[04:41:47] <CaptHindsight> newer versions of RTAI will require fixes to /proc in Linuxcnc
[04:42:00] <LeelooMinai> Man, this doesn't sound very inspiring... Do they have stable realeases or something?
[04:43:04] <CaptHindsight> LeelooMinai: math support in kernel kconfig has changed and no options seem to work with Linuxcnc
[04:43:49] <XXCoder1> time for linuxcncOS fork
[04:43:50] <XXCoder1> ?
[04:44:05] <LeelooMinai> Cannot linuxcnc be, hmm, updated?
[04:44:33] <CaptHindsight> so we are waiting for Paolo to fix the scheduler
[04:44:37] <CaptHindsight> One workaround for the broken scheduler is with isocpu= you need to leave the last cpu core out of the list. For example isolcpus=1,2,3 for a 4 core and it should work or a single core cpu should work fine.
[04:45:49] <CaptHindsight> LeelooMinai: Linuxcnc needs to fix /proc in order for any 3.10 or newer RTAI kernels to work
[04:46:44] <LeelooMinai> Id linuxcnc semi-abandoned project?
[04:46:46] <LeelooMinai> Is*
[04:47:44] <CaptHindsight> http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=shortlog;h=refs/heads/ubc3-7i80 is the repo used that works with preempt_rt and xenomai
[04:48:12] <XXCoder1> night, and heres my parking link
https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-xpf1/t1.0-9/10341635_723693184361904_8298621046749726233_n.png
[04:48:50] <CaptHindsight> LeelooMinai: Linuxcnc works fine as is for most people, development is active and ongoing
[04:50:08] <LeelooMinai> It seems it works fine only if you use pre-made ISO from long time ago.
[04:50:25] <LeelooMinai> NOt if you want to add it to modern pc/os
[04:50:28] -!- dybskiy has quit [Ping timeout: 240 seconds]
[04:50:36] <CaptHindsight> people are using the 3.4.55 RTAI and the above repo with debian wheezy
[04:50:45] <CaptHindsight> also with 12.04
[04:51:31] <LeelooMinai> I cannot install Intel drivers on 12.04 - it's not longer supported
[04:51:50] <LeelooMinai> Also, I think only 32-bit one is supported
[04:52:06] <CaptHindsight> preempt_rt + 14.04 + the above repo should work
[04:52:33] <LeelooMinai> I read somewheree that linuxcnc is only supporting RTAI
[04:52:51] <LeelooMinai> Isn't preempt completely differnt implementation?
[04:53:27] <CaptHindsight> there was development to support xenomai and preempt_rt and that is what that repo has support for, all 3 real time kernels
[04:53:44] <CaptHindsight> http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=shortlog;h=refs/heads/ubc3-7i80
[04:54:25] <CaptHindsight> the changes from that branch should make it into a Linuxcnc release in the next few months
[04:56:58] <CaptHindsight> it's a bit of a challenge when there is only a few active RTAI devs
[04:57:33] <LeelooMinai> Isn't RTAI a big thing much larger in scope than linuxcnc?
[04:58:05] <CaptHindsight> most people don't care for the lunacy of Ubuntu anymore so there's not much interest in 14,04
[04:58:45] <CaptHindsight> yes, RTAI is bigger than Linuxcnc but most of the recent work was only by 3 people
[04:58:48] <LeelooMinai> Normal users probably not, but there are many situations when someone needs real time os to control some hardware
[04:59:33] -!- toner has quit [Ping timeout: 240 seconds]
[05:00:02] <LeelooMinai> O, lunacy... lol... I read latency:)
[05:00:49] <LeelooMinai> Well, I was considering Debian wheezy this morning... but was not sure if I would progress faster there.
[05:01:58] <CaptHindsight> a few people are running it just fine with 3.4.55 RTAI and master or the ubc3-7i80 branch and preempt_rt
[05:02:18] <LeelooMinai> 64 bit version?
[05:02:45] <CaptHindsight> 32
[05:03:03] -!- Fox_Muldr has quit [Ping timeout: 240 seconds]
[05:03:42] <CaptHindsight> can you use the ubc3-7i80 branch and preempt_rt for your board?
[05:04:09] <LeelooMinai> Hmm... what about those old 10.04 .isos? DO they use RTAI?
[05:05:30] -!- Fox_Muldr [Fox_Muldr!quakeman@frnk-5f744cc5.pool.mediaWays.net] has joined #linuxcnc
[05:05:31] <LeelooMinai> CaptHindsight: I don't know - I guess tomorrow and next days I will try to get something running.
[05:06:13] <LeelooMinai> It's all pretty confusing I must say - and I used to be a programmer
[05:06:36] <LeelooMinai> All those versions of everything that work only in some obscure combinations
[05:09:34] <CaptHindsight> most people are using older hardware and the older 10.04 works fine for them
[05:09:54] <CaptHindsight> RTAI doesn't have a lot of devs
[05:10:47] <CaptHindsight> for the past year the new development goes on at
https://github.com/ShabbyX/RTAI/
[05:11:16] <CaptHindsight> after it works there pablo takes it and reworks it into the repo at RTAI.org
[05:12:33] -!- toner [toner!~ink@c-71-198-91-97.hsd1.ca.comcast.net] has joined #linuxcnc
[05:12:42] <CaptHindsight> then NTULINUX and ShabbyX take the RTAI.org and rework it at
https://github.com/ShabbyX/RTAI/ later, rinse , repeat....
[05:14:42] <CaptHindsight> the ubc3-7i80 is new work based on the older mah branch that added support for xenomai and preempt_rt
[05:15:30] <LeelooMinai> Are those two more lively than RTAI?
[05:15:44] <CaptHindsight> so in the next few months hopefully linuxcnc will have an official release with support for RTAI, xenomai and preempt_rt
[05:17:02] <CaptHindsight> yes, but now it's stalled waiting for the scheduler fix
[05:18:11] -!- Tecan has quit [Quit: Live Long And Phosphor!]

[05:21:45] <LeelooMinai> I have Asus MB with parallelport (but pretty modern one) with Haswell Celeron for now. BUt I plan to buy one of those Mesa fpga boards - 5i25 I believe - the one with spartan 6, and use those instead of the parallelport for my cnc machine.
[05:22:11] <CaptHindsight> if you are using servos or hardware stepping then I'd recommend just using preemp_rt
[05:22:44] <LeelooMinai> "just"? Is it simpler than RTAI and that other one?
[05:22:50] <CaptHindsight> yes
[05:23:58] <LeelooMinai> ok, thx for that info - going to sleep now, and will do more research tomorrow

[17:00:30] <zeeshan|3> my friends tools are funny
[17:00:49] <zeeshan|3> so he had an allen key bolt we had to hold to be able to stop a shaft from turning and be able to remove a nut from it
[17:00:58] <zeeshan|3> well his allen key itself 6mm sheared
[17:00:58] <zeeshan|3> completely
[17:01:27] <zeeshan|3> when i say sheared, i mean the HEX turned into a round face
[17:01:28] <zeeshan|3> lol
[17:01:51] <zeeshan|3> whoever made this made this out of mild steel :p
[17:07:29] <kfoltman> how does one go about milling HDF?
[17:08:00] <IchGuckLive> on high RPM
[17:09:30] <CaptHindsight> zeeshan|3: the cheapo HF keys do this all the time, they are more like break-away max torque setting keys since they tend shear off or round
[17:09:39] <zeeshan|3> lol
[17:09:59] <zeeshan|3> i mean fuck allen keys from a made in usa supplier are so cheap
[17:10:02] <zeeshan|3> why buy hf non sense :P
[17:11:19] <CaptHindsight> it's a safety feature :)
[17:11:23] <zeeshan|3> hahah
[17:12:47] <CaptHindsight> a cheap 3/8" socket extension made it into one of my tool boxes, when I torqued it once to >40ft lbs it twisted ~90 deg
[17:12:56] <zeeshan|3> ROFL
[17:13:12] <CaptHindsight> no brand name on it
[17:13:12] <zeeshan|3> im trying to determine the wire size for my 2 power supplies since i'm about to put them in permanently
[17:13:27] <zeeshan|3> 60W and 1300W so total of 1360W
[17:13:44] <zeeshan|3> so worse comes to worse, the voltage my drop to 110VAC
[17:13:47] <CaptHindsight> what voltage?
[17:13:55] -!- zzolo has quit [Quit: zzolo]
[17:13:57] <zeeshan|3> so 12.36A
[17:14:03] <CaptHindsight> (to determine current)
[17:14:09] <zeeshan|3> i'm thinking i can get away with a 16 gauge
[17:14:12] <zeeshan|3> its rated for 13A
[17:14:22] <zeeshan|3> (for house purposes|)
[17:14:26] <zeeshan|3> but in reality, it'll handle more.
[17:14:37] <zeeshan|3> and its only a 4 foot run
[17:15:35] <CaptHindsight> monster cable #000 should do it :)
[17:15:35] <zeeshan|3> yea a 90C conductor is rated in reality for 18amps
[17:16:03] <zeeshan|3> i just need to check how much my computer draws
[17:16:09] <zeeshan|3> actually it doesnt matter
[17:16:19] <zeeshan|3> it's on 2 seperate 15 A breakers
[17:16:50] <archivist> make sure it is oxygen free for hifi /me ducks

[17:29:50] <ssi> IchGuckLive: I have a candcnc LC-THC
[17:29:58] <ssi> and I can't remember offhand if it's using the 50:1 or taking direct arc
[17:30:02] <ssi> I tihnk it might be taking direct arc
[17:30:12] <CaptHindsight> ssi: if it's between a load center and a receptacle it has to follow code, if it's in his control cabinet it's up to him
[17:30:56] <ssi> code is boring :)
[17:31:31] <CaptHindsight> ssi: code tends to follow lots of tradition with some science behind it
[17:32:00] <ssi> heheh
[17:33:16] <ssi> IchGuckLive: yeah I'm looking at the lcthc manual and there's a sensor board that I'm pretty sure is inside my power supply, and it's got a high voltage sensor
[17:33:52] -!- jduhls has quit [Quit: Leaving]
[17:34:19] <CaptHindsight> we had to use all sorts of odd formulas for wire sizing, and sizing could changed based n the type of load, (resistive, inductive, data center) and even the type of location (home, health care center, factory)
[17:34:31] <ssi> that's unfortunate.... that means I won't be able to wire everything via the CPC :(
[17:34:56] amnesic is now known as amnesic_away
[17:35:00] <IchGuckLive> i got only good results on direct moving at >5m/min below the 50:1 given mutch better movement
[17:35:15] <ssi> IchGuckLive: I didn't parse that at all :)
[17:35:46] <IchGuckLive> it maybe smoothes the Volt calculation more efficant

[17:37:17] <CaptHindsight> the number of current carrying conductors in the same raceway also throws people, or why the neutral in a 3-phase circuit has to be 1 wire size larger than the other conductors in a data center
[17:37:53] <CaptHindsight> 3-phase wye, not delta
[17:41:42] <ssi> I wonder how hard it would be to abandon the LC-THC and do a custom thc within linuxcnc
[17:42:01] <ssi> I'd need an analog in
[17:42:14] <IchGuckLive> pcew board
[17:42:41] <IchGuckLive> this gives you all te values

[17:44:02] <IchGuckLive> i got the polen THC in use
[17:45:28] <ssi> the one thing I don't like about the lcthc is that the voltage parameter is controlled on its own little controller
[17:45:33] <ssi> meaning I can't change it in g code
[17:45:37] <IchGuckLive> i also hacked in a plasma ready to fire as i use Arc-ok signal to detect arc has firered
[17:45:42] <ssi> I have to remember to dial it if I change thicknesses
[17:47:18] <pcw_home> Theoretically you can do a little better with a A-D and linuxcnc in the case linuxcnc controls the motion
[17:47:20] <pcw_home> (since you can use a proportional control and not just go-up, go-down)
[17:47:38] <ssi> pcw_home: yeah... it seems like that would afford me a fair bit of flexibility
[17:48:04] <ssi> pcw_home: so the 10v model with my hypertherm's 50:1 output (7v max according to manual) would be the way to go, yeah?
[17:48:07] <pcw_home> unfortunately the current THC hal component doesn't do this
[17:48:38] <ssi> that's ok, software is flexible :D
[17:49:18] <ssi> I wonder if I should get a 7i76 at the same time and put it in between my 5i25 and gecko, so I have better IO options
[17:49:48] <ssi> I'll lose the simplicity of the one-cable wiring, but probably a worthwhile tradeoff
[17:50:29] <pcw_home> probably too much I/O, I would just get a simple BOB for the second connector

[17:53:09] <IchGuckLive> oh sowwy no the homing is not includet
[17:53:20] <ssi> IchGuckLive: that's how I had it before, but I needed ONE more input because I have to home both gantry joints simultaneously
[17:53:23] -!- kfoltman has quit [Quit: Ex-Chat]
[17:53:25] <ssi> which I still haven't finished yet :)
[17:53:50] <ssi> so I went ahead and wired them all to independent inputs, since once I added the second port I had plenty to spare
[17:53:54] <Connor> I want to replace my parport card with a 5i25.. I have a el-cheap-o C10 Bi Directional from cnc4pc.com
[17:53:57] <ssi> my X axis max and min limits are a shared pin
[17:54:00] <IchGuckLive> it works here i simply hacked the trivkinetiks
[17:54:10] <Connor> the PC and BOB in the same case, so I use the internal connector..
[17:54:20] <ssi> Connor: 5i25 is a great product
[17:55:20] <mozmck> The newest CandCNC THC does proportional control. If I can knock some other projects out we plan to support it on Linuxcnc this year.
[17:55:29] <Connor> Yea.. so.. I could get the 7i76.. I have 3 axis, charge-pump, a PWM-to-0-10v card for the Spindle, and a encoder coming in from the spindle.
[17:55:41] <Connor> the 7i76 would handle ALL of that, and give me the added IO I need.
[17:55:43] <ssi> Connor: yep
[17:56:04] <ssi> mozmck: who's 'we'?
[17:56:19] <Connor> I would use the 2nd connector on the 5i25.
[17:56:25] <Connor> so it would stay internal.
[17:56:55] <mozmck> ssi: me! I work for candcnc - mostly writing the firmware/software now.
[17:57:03] <ssi> ahh
[17:57:10] <ssi> I have an old lc
[17:57:10] <Connor> I could get the 5i25 and use it with the existing BOB for a while.
[17:57:24] <ssi> probably four years old?
[17:58:16] <ssi> like I said, it's worked fine for me, but I'd prefer to be able to use the 50:1 output of my power supply, and I'd prefer to be able to set arc voltage in linuxcnc instead of having to remember to dial it
[17:58:32] <IchGuckLive> im off bye
[17:58:35] <mozmck> Yes, we did that a while back now. The new one can be setup through rs485

[17:58:49] <ssi> when I built this table, I took path of least resistance, and so lc and mach were an expedient option :)
[18:00:29] <mozmck> :) We are planning to not have mach as our only option as soon as is feasible.
[18:00:47] <ssi> that would be wise!
[18:00:57] <ssi> out of curiosity, is there an upgrade path for older units?
[18:01:28] <mozmck> Yes, to some degree, but I don't know the details. You'd have to call Tom about that.
[18:01:39] <ssi> ok
[18:02:13] <ssi> I'm gonna order peter's thcad and see what I can get working in linuxcnc first, that seems like a pretty solid option, but might require some significant hal hacking
[18:02:23] <ssi> I definitely like the idea of simplifying
[18:02:35] <ssi> simplifying hardware wise that is :)
[18:02:38] <mozmck> yes.
[18:04:44] <ssi> pcw_home: 7i75 would be a good option for breaking out that internal port, yeah?
[18:05:39] <pcw_home> Yeah it provide some protection but allows any pin diection
[18:06:25] <pcw_home> you can also just use generic BOBs
[18:06:53] <ssi> yeah but I don't have a generig BOB on hand, but I am about to order a thcad :D

[18:16:48] <pcw_home> Nah there's alway cheaper way
[18:17:23] <ssi> there's cheap and then there's value... using a BOB from someone else means placing a second order, with a second shipping cost
[18:17:33] <ssi> plus your products are solid, and I prefer uniformity in the pluggable phoenix blocks
[18:17:46] <ssi> worth the $20 or so more that the '75 would be over someone else's BOB
[18:18:53] <ssi> the cheaper way is the way I have it now, which is a bare DB25 connector floating in midair ziptied to the wall :)

[18:39:06] <ssi> holy wiring batman
[18:39:20] <Connor> What?
[18:39:25] <archivist> too tidy must shuffle it a bit
[18:39:28] <ssi> heheh
[18:39:57] <ssi> Connor: top unit your spindle drive?
[18:40:01] <Connor> You saying my wiring is messy ?
[18:40:07] <ssi> I'm not saying anything :D
[18:40:27] <Connor> yes. that's the KBIC reversing controller
[18:40:33] <ssi> gotcha
[18:40:45] <Connor> I tried to keep it neat.. but.. the BOB sucks.
[18:40:53] <ssi> yeah get you a 7i76 kit
[18:40:59] <ssi> that'd be ideal for you
[18:41:12] <Connor> hope it'll fit in that space.
[18:41:30] <Connor> some of that wiring mess is the PC PSU wiring..
[18:41:36] <ssi> https://scontent-b-mia.xx.fbcdn.net/hphotos-xfa1/t31.0-8/459136_10100131793367542_829866394_o.jpg

[18:42:44] <archivist> ssi, at least you got all teh wires the same colour so they could not be wrongly wired (except mains)
[18:42:51] <Connor> most of the messy wires are for the spindle encoder, and estop stuff
[18:42:53] <ssi> archivist: exactly :)
[18:43:11] <archivist> ssi we wired a boat that way once :)
[18:43:22] <ssi> archivist: that's standard procedure in airplanes :P
[18:43:39] <Connor> WHy in the world use the same color?
[18:43:41] <ssi> that's milspec wire from ye olde airplane parts store
[18:43:50] <archivist> proper is not writing a wire number on the ends :)
[18:44:06] <ssi> yeah wire numbering would be nice, but I didn't bother :)
[18:44:12] <ssi> it's small enough that it can be rung out

[18:44:47] <Connor> Well.. other than my wire mess.. how does it look mounted under the tray and my tool shelf ?
[18:44:55] <ssi> very good
[18:45:19] <ssi> the only thing that'll be weird about the '25/'76 combo for your setup is it's sorta setup for the interface board to be separate from the PC
[18:45:23] <Connor> and the wires for the step/dir and stepper outputs are nice and neat.
[18:45:45] <ssi> https://scontent-b-mia.xx.fbcdn.net/hphotos-xfa1/t1.0-9/262501_10100133915824122_1848380283_n.jpg
[18:45:47] <Connor> ssi: That's what I was saying.. I need to use the 2nd internal interface.
[18:46:00] <ssi> well the 7i76 doesn't work that way
[18:46:08] <Connor> yes it does.
[18:46:12] <ssi> well yeah I guess it does
[18:46:15] <ssi> but you'll need the right cable
[18:46:18] <ssi> might have to make it
[18:46:18] <Connor> You can use it on either of the 5i25 ports
[18:46:29] <Connor> I have it. standard parport to db25
[18:46:34] <ssi> need a 26 pin IDC to DB25 male
[18:46:35] <Connor> what I'm using on the BOB right now.
[18:47:06] <ssi> ah I see you have a gender changer in there
[18:47:10] <Connor> it's the ribbon cable.. with the gender bender on it.
[18:48:15] <Connor> my setup for the estop and spindle encoder is a bit odd.. both use the DB9 connector..
[18:48:17] <jdh> I can bring you one when i pick up the lathe.
[18:48:21] <Connor> and it's a "flying lead"
[18:48:28] <Connor> jdh: What lathe?
[18:49:00] <jdh> ssi's g0602
[18:49:08] <ssi> bring me one what
[18:49:27] <Connor> comes out and has another db9 connector that goes to the e-stop switch and then continues on up to the spindle encoder..
[18:49:46] <Connor> was running out of room for connectors
[18:50:19] <jdh> oh. nevermind
[18:50:33] <Connor> I have 1 spare 4 pin connector for 4th axis.. and 1 4 pin for the limits-homes
[18:50:35] <jdh> short scrollback
[18:51:15] <PCW> we do have the second DB25 bracket/cable assy
[18:51:18] <Connor> so, 5 x 4-pin connectors, 1 x for the spindle output and 2x for AC input. (Spindle and Stepper)
[18:51:49] <Connor> PCW Basically the same thing I'm already using.. no ?
[18:52:05] <Connor> just a ribbon cable with bracket ?
[18:52:07] <ssi> PCW: on the 7i76 firmware for the '25, what is the internal connector set up for? A second 7i76?
[18:52:15] <PCW> Yes ist the standard second PP thing
[18:52:20] <PCW> its
[18:53:19] <PCW> Yes (7I76X2) but if you want to use the header you should use 7I76X2R
[18:53:37] <ssi> Connor: take note of that
[18:53:39] <Connor> I DO have one free open slot.. so I could manufacture some sort of db-25 to db-25 with a bracket.. and use a short cable on the outside.
[18:53:44] <PCW> (which swaps the connectors)
[18:54:05] <ssi> Connor: nah internal cable the way you're doing it now should be fine
[18:54:23] <Connor> Yea. shouldn't need the extra db 25 for anything.
[18:54:25] <ssi> but note the different firmware; you may be able to order it preflashed, or you may need to do it yourself
[18:54:29] <Connor> if I use the 7i76 BOB
[18:54:45] <Connor> not a issue either way.
[18:54:52] <ssi> I think the point is that the reversed firmware puts the 0-3 stepgens on the internal connector rather than the external one
[18:55:02] <PCW> Yep
[18:55:04] amnesic_away is now known as amnesic
[18:55:13] <Connor> puts everything on it..
[18:55:19] <Connor> which is exactly what I would need
[18:55:24] <ssi> well no not everything; the firmware is set up to run two '76s
[18:55:31] -!- ZinovaS_ has quit [Quit: Konversation terminated!]
[18:55:42] <ssi> but the order of the stepgens and IOs would be reversed on the reversed firmware, which will be more convenient
[18:56:53] <Connor> I wish I had some sort of DIN rail in it.. instead of using the stupid bearer strips for the DC output..
[18:57:10] <Connor> I left room for 3 more stepper controllers.
[18:57:31] <Connor> lotta stuff packed into the case..
[18:57:54] <Connor> need lunch.. back in a bit
