[00:57:34] <SpeedEvil> Stupid question. Is there any reason why simply putting two steppers on either end of a shaft is bad?
[00:58:57] <jfigie> you want to do this to get 2X the torque?

[01:03:36] <jfigie> I suspect that you will not always get 2X torque because the steps will not be in perfect alignment between the 2 motors
[01:03:55] <SpeedEvil> yeah
[01:04:11] <SpeedEvil> I have a barrel full of steppers pulled from hard drives.
[01:04:11] <jfigie> I think you could do this with servo motors if configured the right way

[01:05:02] <andypugh> There are mechanical arrangements that let you use multiple motors. But I don’t think any of them offer zero (or even low) backlash.
[01:05:22] -!- PetefromTn_ has quit [Quit: IceChat - Keeping PC's cool since 2000]
[01:06:12] <SpeedEvil> The steppers have exposed far ends, so I can add a bearing for preload

[07:11:41] <archivist> I have used it often
[07:13:51] <Flipp> do you create your own parts for things like Nema17 motors, 623zz bearings, etc?
[07:13:54] <Flipp> or do you find them online?
[07:13:58] <archivist> anarchos, the bigger problem is how will you program your mill
[07:14:11] <archivist> Flipp, make my own usually
[07:15:28] <Flipp> archivist: ah, ok. I figured there may be a repository for "standard" stuff, but from what I can tell there isn't a readily-available library
[07:15:38] prtksxna is now known as zz_prtksxna
[07:15:42] <archivist> some stuff is so easy to create that it is quicker to just do it rather than search

[07:33:02] <anarchos> might have some stuff you are looking for
[07:35:55] <anarchos> archivist: i never thought that far ahead. there must be CAM software that can do it though, right?
[07:36:34] <archivist> yes but at a price 99.9999% of hobbyists cannot afford
[07:37:02] <anarchos> piratebay? :P
[07:37:06] <archivist> you can write kins to make programming it easier

[09:37:29] <Loetmichel> cleaned
[09:37:55] <Loetmichel> luckily i have a good immune system and heal really fast
[09:38:27] <Loetmichel> (maybe because i am a little clumsy and my body is used to mend some injuries?) ;-)
[09:46:08] <Jymmm> Loetmichel: Um, maybe you should NOT be operating machinery =)
[09:46:30] <Loetmichel> as long as it heals fast
[09:46:32] <Loetmichel> ;-)
[09:47:18] <Loetmichel> ... maybe i should stick to coffee out of starbucks tumblers in the morning. at least 'til i am awake and not on "autopilot" ;)

[09:49:05] <Loetmichel> is that the english word for "schnabeltasse"?

[09:51:42] <kfoltman> " it's GTK widgets placed on top of a image file:"
[09:52:10] <kfoltman> someone made a mach3 screenshot and made it a virtual faceplate for linuxcnc? :D
[09:52:18] <Jymmm> Yeah, like lcnc has c:\Mach3\...
[09:52:51] <kfoltman> it's a screenshot with only coordinates overlaid using linuxcnc
[09:53:05] <Jymmm> I still call bullshit on it
[09:53:09] <kfoltman> "The axes DROs in this pic are actual numbers from a running linuxcnc"
[09:53:17] <kfoltman> only DROs, not the rest of the widgets I think
[09:53:20] <Jymmm> Again, BS
[09:54:08] <kfoltman> uh, have you seen other screenshots from that page?
[09:55:09] <kfoltman> I don't know linuxcnc much, or gscreen at all, but it looks like it's a front-end with customizable/user-defined layouts
[09:55:53] <kfoltman> so you have several variants of its own layout, plus a novelty/hack layout that uses a mach3 screenshot as a background

[10:09:40] -!- Thetawaves [Thetawaves!~Thetawave@] has joined #linuxcnc
[10:16:26] <kfoltman> the sound is horrendous
[10:16:53] <SpeedEvil> Clearly, there are problems with rigidity.
[10:17:03] <SpeedEvil> But, does that always impact cutter life?
[10:17:11] <Jymmm> Viagra?
[10:17:16] <SpeedEvil> Especially if it's say a carbide bit in Al, with lots of coolant
[10:19:04] <Jymmm> Are there any 2D CAD that can maintain/replicate sections of a drawing? Lets say you have a set hole pattern, but need to alter it's length
[10:20:19] <SpeedEvil> openscad comes to mind
[10:20:37] <Loetmichel> sounds like grossly overloaded spindle

[10:21:03] <Jymmm> http://www.openscad.org/gallery.html

[10:23:41] <kfoltman> GUI? why would you need a GUI?
[10:24:31] <kfoltman> Loetmichel: you mean the squeaky/grindy sound is a sign of not enough spindle power?
[10:24:48] <SpeedEvil> Jymmm: Well - not as you might expect.
[10:24:51] <SpeedEvil> https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/First_Steps/Creating_a_simple_model
[10:25:10] <Loetmichel> kfoltman: no
[10:25:10] <SpeedEvil> It's got a text editor, which can update live with your changes.
[10:25:23] <SpeedEvil> But it's all 'cube at x,y,z' rather than mouse driven
[10:25:25] <Loetmichel> the spindle revving down on the first cuts is
[10:25:39] <Jymmm> SpeedEvil: Yeah, I'm looking for 2D, not 3D for one =)
[10:25:43] <kfoltman> Loetmichel: ahh, makes sense
[10:25:51] <SpeedEvil> Jymmm: Don't type the Z
[10:26:07] <kfoltman> Jymmm: I did some 2d stuff with it too
[10:26:18] <Loetmichel> the squeaky sound is because of a much to deep cut for the sleek rest of aluminium thats left to hold the dice at later cuts
[10:26:54] <Loetmichel> i can do that, too
[10:27:29] <kfoltman> Loetmichel: ok, so if the machine makes that sort of sound, I should reduce plunging speed?
[10:27:38] <SpeedEvil> kfoltman: it's a warning sign
[10:27:48] <SpeedEvil> That means you should really think hard about what you're doing
[10:28:14] <SpeedEvil> Same as with tyres that make that sort of noise
[10:28:22] <SpeedEvil> In some cases, it's quite safe and controllable.
[10:28:27] <Loetmichel> https://www.youtube.com/watch?v=UEd4LCJ3uWk <- 1meter long suare aluminium tube
[10:28:37] <SpeedEvil> In other cases it's a prelude to bits of metal sticking into you
[10:28:43] <Loetmichel> should have put some sand in to dampen the resonances ;-)
[10:29:05] <Loetmichel> kfoltman: not plunging speed
[10:29:09] <Loetmichel> cutting depth
[10:29:19] <kfoltman> Loetmichel: I meant the rate of descent in each layer
[10:29:24] <kfoltman> probably used the wrong term
[10:29:27] <Loetmichel> less material to cut-> less forces on the material
[10:29:32] <kfoltman> ok
[10:29:50] <Loetmichel> -> less chance of flying workpieces ;-)

[10:33:41] <kfoltman> 1/8" collet
[10:33:59] <Loetmichel> mine can, up to 8mm
[10:34:37] <Loetmichel> but i have some stepped sheet metal drills that fit into a standard drill press
[10:34:42] <Loetmichel> i just didnt find them
[10:35:12] <Loetmichel> these: http://www.pollin.de/shop/dt/OTQ1ODk0OTk-/Werkstatt/Werkzeuge/Bohrer_Fraeser_Bits/HSS_Stufenbohrer_Set_in_Metallkassette.html
[10:42:08] <kfoltman> Loetmichel: what's a good source for cheap large carbide bits with 1/8" shaft?
[10:42:17] <Loetmichel> hu?
[10:42:25] <Loetmichel> buy big ones and grind them off
[10:42:38] <Loetmichel> i know of none that makes them readily aviable
[10:42:38] <kfoltman> huh? how? :D
[10:42:46] <kfoltman> large as in >2mm
[10:42:49] <Loetmichel> with a diamond disc and a lathe?
[10:42:50] <kfoltman> not as in >20mm :)
[10:42:55] <kfoltman> a lathe!
[10:43:03] * kfoltman imagines his wife's face if he bought a lathe
[10:43:13] <kfoltman> and I don't mean "more round"
[10:44:09] <kfoltman> sorotec has some 3-5mm drill bits, but they're bit pricey
[10:45:03] <kfoltman> OTOH it would probably still save some bucks by not wasting endmills on plain round holes
[10:45:42] <Loetmichel> depends
[10:45:51] <Loetmichel> i tend to do anything with 2mm endmills
[10:46:36] <Loetmichel> https://www.youtube.com/watch?v=BXNhsid6PD0 <- even 2,5mm holes ;-)

[16:38:12] <XXCoder> that is other way yes, but no way to mount it like that and attach it to router
[16:38:15] <IchGuckLive> i got a hole 150pages catalog here of dials and indicators

[16:41:59] <IchGuckLive> Pitch 5mm O.O
[16:42:21] <XXCoder> lemme review
[16:42:27] <agile_netvark> XXCoder, what you're looking for is an "indicator lug back"
[16:42:27] <IchGuckLive> 2005
[16:42:31] <IchGuckLive> 2505
[16:42:38] <agile_netvark> note that there are magnetic backs available, too

[16:42:45] <IchGuckLive> 2525
[16:43:20] <XXCoder> agile_netvark: thanks. since my machine will be mostly wood magnetic wont be any use :) but thanks for terms
[16:43:46] <somenewguy> IchGuckLive: not at all
[16:43:49] <XXCoder> 1605 apparently acording to site I saw
[16:43:53] <somenewguy> although this is the internet, i guess 2 months is old yeah?
[16:44:15] <IchGuckLive> XXCoder: so 5mm pitch does not fit 400steps pretty good
[16:44:39] <IchGuckLive> a 20/25 gearig or timingbelt woudt be given you best speed at best torqe
[16:44:44] zz_prtksxna is now known as prtksxna
[16:45:14] <IchGuckLive> XXCoder: http://foengarage.de/gears2.html
[16:45:38] <XXCoder> yeah well not much I can do now, while I finally bought a car so I have more budget, I refuse to buy replacement parts while my current existing parts is unused
[16:45:48] <IchGuckLive> timingbelt will see only the same direction effect and no backlash consern
[16:46:06] <IchGuckLive> XXCoder: so stay on 800steps
[16:46:11] <somenewguy> although I have been playing w/ stuff a while, why doyou ask?
[16:46:24] <IchGuckLive> not good for speed and to high precicion
[16:46:47] <IchGuckLive> somenewguy: Nick related only
[16:46:52] <XXCoder> speed isnt exactly my goal. I want 0.01 mm precision
[16:47:06] <XXCoder> it should be pretty easy to meet.
[16:47:17] <IchGuckLive> some new guy 2years of channel confiring
[16:47:55] <IchGuckLive> XXCoder: then you need 400Steps meet 20Teeth = 500steps meet 5mm
[16:48:27] <XXCoder> I don't plan to use any gears
[16:48:33] <XXCoder> direct mount motor to shaft
[16:48:54] <somenewguy> oh well I always feel out of my league, and I am perpetually picking up new projects, so I am always new somewhere
[16:48:56] <IchGuckLive> so 0.01 is not retchable on standard drivers
[16:49:25] <IchGuckLive> 5mm/400steps =0.0125
[16:49:45] <IchGuckLive> 5mm/800=0.00625
[16:49:50] <XXCoder> I probably will use half stepping
[16:50:00] <agile_netvark> well, you can always use 1/2 to 1/32 steps.
[16:50:31] <IchGuckLive> there are driver setups for a 500steps stepper mashine but well out of budget the gear is 20USD or 25Euros
[16:50:43] <XXCoder> what the flipping... http://www.amazon.com/Brown-Sharpe-01460014-Center-Indicators/dp/B004XHFUEM/ref=sr_1_13?ie=UTF8&qid=1404665281&sr=8-13&keywords=dial+indicator+lug+back

[16:51:11] <IchGuckLive> no 9parts at all axis
[16:51:14] <agile_netvark> its a b&s part :P
[16:51:25] <IchGuckLive> if you need that mutch force
[16:51:37] <XXCoder> does it start with bull and end with word for #2 waste? :P

[16:52:05] <somenewguy> they will still generally snap from step to step, depending
[16:52:10] <IchGuckLive> half stepping is ok at 12Nm
[16:52:18] <somenewguy> however they are less prone to lost steps w/ multistepping so its still worth it
[16:52:29] <somenewguy> IchGuckLive: sorry yeah your right, half stepping is the only guarenteed improvement
[16:52:44] <somenewguy> anythign heigher is dependent on the stepper, no clue how one would measure it easily

[17:00:45] <IchGuckLive> hi jfigie
[17:00:52] <jfigie> Hi
[17:01:17] <IchGuckLive> got a question ask ;-)
[17:01:53] -!- mascape has quit [Quit: ChatZilla [Firefox 30.0/20140608211132]]
[17:02:05] <XXCoder> my dial indicator is around 53 mm
[17:02:09] <XXCoder> diameter
[17:02:19] <IchGuckLive> T10*Z12 =120mm this is the working diameter of the pinion calculation on full presure load to the rack
[17:02:39] <IchGuckLive> XXCoder: so you got 6-10mm movement inside
[17:02:47] <IchGuckLive> with 0.01 precission
[17:02:49] <XXCoder> it does say 0-10mm
[17:03:10] <IchGuckLive> yeah there are also 0-6
[17:03:52] <XXCoder> wow finding compitable lug back is hard
[17:03:55] <IchGuckLive> on best use go to 3mm and then drive your way or do a mashine stop at that value
[17:04:06] <XXCoder> its almost easier to just buy another dial indictor, one with lug back
[17:04:28] <IchGuckLive> Best to go
[17:05:29] <XXCoder> is my dial indictor 2 1/4 diameter? I figured it to be 2.08
[17:05:37] <IchGuckLive> jfigie: where in the world are you im in germany

[17:10:35] <jfigie> yes it has been cool here the last several days
[17:10:46] <agile_netvark> jfigie, wow. since when do you measure in °C in 'murica? :D
[17:11:00] <IchGuckLive> as most in the East Hurricane Related 4th of july
[17:11:31] <jfigie> I am an electrical engineer. I prefer to use C. Every one else uses deg F
[17:11:34] <IchGuckLive> agile_netvark: whre are yoiu from
[17:12:04] <XXCoder> I usually use F but just because I was rainsed on it. I prefer metric too
[17:12:05] <agile_netvark> jfigie, ++ :D

[17:13:12] <jfigie> I think a lot of them will provide either
[17:13:12] <IchGuckLive> never saw one of them in anay store
[17:13:13] <agile_netvark> sensors usually just output general values which need conversion
[17:13:43] <IchGuckLive> agile_netvark: agree ohm is then processed

[17:16:36] <IchGuckLive> XXCoder: why dont you use your dial you got and mount it in any wood block
[17:16:47] <XXCoder> how do I mount it?
[17:16:48] <IchGuckLive> XXCoder: got a pic of yours
[17:16:52] <XXCoder> a sec
[17:17:12] <XXCoder> http://www.aliexpress.com/snapshot/6133272546.html
[17:17:20] <IchGuckLive> as it is standard 2inch 53mm it is a mountable
[17:17:43] <IchGuckLive> the Big 8mm Pin is the mount
[17:18:00] <IchGuckLive> the 6mm pin is the moving part
[17:18:08] <IchGuckLive> so be carfull with your clamp
[17:18:17] <XXCoder> yeah I have it in hand I figured that :)
[17:18:18] <IchGuckLive> as it moves inside the mounting pin
[17:18:27] <XXCoder> yeah not too tight and all
[17:18:47] <IchGuckLive> DONE
[17:18:49] <XXCoder> so my only choice is to mount it using that non-moving shaft
[17:19:01] <IchGuckLive> yes
[17:19:28] <IchGuckLive> the magnet holder provides usaly the angle direction and al the kind of tricks
[17:19:57] <IchGuckLive> get a arm on it and then go ahad
[17:20:13] <IchGuckLive> you can put it in ypour spindle hole
[17:20:23] <XXCoder> something like http://www.aliexpress.com/item/Universal-miniature-table-seat-magnetic-table-Mechanical-Leverage-dial-indicator-holder-Leverage-dial-gauge-block-Magnetic/1904459851.html
[17:20:25] <XXCoder> ?
[17:20:37] <IchGuckLive> but i got a simple 10mm plate of wood i stick it into and then fix this inside Z
[17:20:59] <IchGuckLive> to flat mashure the table
[17:21:21] <XXCoder> not bad. get a arm, mount it to Z somehow, it will work
[17:21:35] <jfigie> But I have found that the cheep magnetic bases have weak magnets.
[17:21:47] <IchGuckLive> as your spindle is a 20mm hole if you choose a Proxxon you can go for a wood broom to fix it
[17:21:56] <XXCoder> yeah its VERY weak on wood, jfigie ;)
[17:22:09] <jfigie> LOL
[17:22:27] <XXCoder> the arm is useful, and removable.
[17:22:33] <IchGuckLive> XXCoder: there are also screwed holders
[17:23:09] <IchGuckLive> XXCoder: http://www.praezisionsmesstechnik.de/mwgpt/messstative/produkte.html
[17:23:58] <XXCoder> one store sells just arm for $30. and I already found $18 buck for everything including magnet base lol
[17:24:16] <XXCoder> some people is nutty
[17:24:21] <IchGuckLive> yes you can spend alot on this
[17:24:46] <IchGuckLive> with no benefit
[17:25:23] <IchGuckLive> simply move the Z to the mid point XY and messure with a fix block to the corners
[17:25:30] <IchGuckLive> 0.02mm done
[17:26:09] <IchGuckLive> or find the highest corner and mut all 3 others to that value up
[17:26:22] <IchGuckLive> as 3D printer do
[17:27:03] <IchGuckLive> on CNC eighter move your SBR or the table plate by putting pater under the slide
[17:27:29] <IchGuckLive> Between the Table plate and the moving wagon
[17:27:39] <IchGuckLive> ;-)
[17:28:04] <IchGuckLive> if it more then 0.5 correct your frame first
[17:29:05] <XXCoder> I probably would fix one rail and leave other rail bit loose, move gantry to one end, screw one hole in sbr rail, move gantry down to other end, screw rest down
[17:29:16] <XXCoder> it should make rails very parallel to each other

[20:08:47] <CaptHindsight> anarchos2: ask away
[20:08:55] <anarchos2> obviously the apt-sources are set to a linuxcnc repository? so it's safe to use aptitude upgrade?
[20:08:56] Ecliptic is now known as FreeHand
[20:09:37] <CaptHindsight> ues, to update packages but not upgrade to a higher version of Ubuntu (say 8.04 to 10.04)
[20:10:13] <anarchos2> gotcha, so as long as i don't mess with the apt-sources list, i should be good
[20:10:14] <CaptHindsight> sudo apt-get update followed by sudo apt-get upgrade is safe

[20:10:31] -!- bpuk [bpuk!~ben@boopotter.plus.com] has joined #linuxcnc
[20:11:18] <bpuk> Evening all. Can anyone tell me if I can use a 5i25 and a 5i20 in the same system? (dead drive, looking for a quick solution from my parts bin while waiting for replacement)
[20:11:39] <ssi> sure
[20:12:28] <cradek> that's a well-stocked parts bin
[20:13:40] <anarchos2> are there any open source CAM/GCode generators?
[20:14:02] <cradek> yes, more or less
[20:14:12] <bpuk> the 5i20 is from a machine I've stripped for parts - don't have any spare step/dir cards for the 5i25 - but do for the 5i20. After 12 hours debugging today to find the problem my head has kinda gone - so that's a relief
[20:14:43] <cradek> 5i25 can output step/dir just fine with no additional card
[20:15:25] <bpuk> strip a parallel cable and connect directly to the drive?
[20:15:50] <cradek> yep you can just wire it up as if it's a normal parallel port
[20:16:18] <bpuk> That's even better :)
[20:16:48] <cradek> my drives have optos on the inputs; that's best, but not strictly needed
[20:17:16] <cradek> be aware you may have to reprogram the 5i25 with an appropriate firmware
[20:17:27] -!- kfoltman has quit [Quit: Ex-Chat]
[20:17:35] <cradek> but that's something you can do yourself

[20:17:56] <cradek> aha, then it's already parport-like
[20:18:21] <bpuk> I've got a gecko G201X that I'm planning to use as the temp fix - I think that's optoisolated to start with
[20:18:46] <bpuk> so shouldn't be too bad. Thanks :)
[20:19:12] <cradek> I didn't read back - you're trying to work around a failed g540?

[20:20:03] <bpuk> Didn't post that bit - but yes - one drive is losing steps in one direction only - swapped cables, fault moved. Might be the parallel cable, but I doubt it
[20:20:58] <cradek> ah, sounds tricky to troubleshoot
[20:21:09] <bpuk> hence the 12 hours :)
[20:21:26] <cradek> ick
[20:21:29] <bpuk> I was convinced it was binding (since the Y and A are slaved) - I was getting racking
[20:21:48] <cradek> sleep, eat, then look at it again
[20:22:07] <bpuk> On a side note - part of the debugging process was dropping accelerations in the hope of fixing the problem. I've now gone back up to much higher than I had before (300 mm/sec/sec instead of 175). The new trajectory planner is _awesome_. Big thanks to Robert and Sam on that one
[20:22:24] <cradek> yep those guys are great
[20:24:14] <bpuk> Indeed. The plan is to sleep, eat, then swap the 5i25 for the spare, swap the parallel cable for a fresh one - if the problem persists order a replacement G250 and rig up the other drive as a fix
[20:25:29] <somenewguy> the 5i25 is just an isolator basically, right?
[20:25:34] <somenewguy> for an lpt port, same notion as the motherboard for a G540?
[20:25:35] <cradek> no
[20:25:41] <cradek> totally different
[20:25:51] <somenewguy> oh ok, part number sounded familiar
[20:26:04] <cradek> 5i25 has a parport-like connector, but has a smart fpga setup behind it
[20:26:26] <cradek> it can generate pulses/pwm/count encoders/etc just like the pci cards
[20:26:34] <somenewguy> anarchos2, if you go into update settings you can tell it to "never tell me about new ubuntu release" and that makes it less anoying imho
[20:26:39] <somenewguy> oh ok
[20:27:25] <somenewguy> i was hoping he was bypassing a possibly bad board w/ the card I am thining of (ill need to look up the pn)
[20:27:38] <somenewguy> cause thats exactly what I am going to do, but I can't decide if I should do it w/ a gecko board or a mesa board
[20:28:16] <somenewguy> anarchos2: ther is heekscad, which makes models but I don't like too much, I prefere freecad
[20:28:31] <somenewguy> however heeksCNC is a plugin for heekscad that will generate gcode, which does work
[20:29:03] <somenewguy> I only finally just got heekscad/cnc installed and working last week, as there was a HUGE flurry of activity w/ heekscad finally having a 1.0 release, tons of repos got update etc etc
[20:29:06] <bpuk> somenewguy: it has the advantage of being much cheaper if you don't need all that much i/o - it's still at least 3 times the i/o of a parallel port. I use a 5i20 on the lathe and a 5i22-1.5 on the mill. The 5i25 is more than adequate for the router.
[20:29:58] <somenewguy> if you are running ubuntu there is a ppa for all the LTS releases of heekscad, the only way I was able to succesffuly install it. I'm no computer genius,but I rank myself high in the google-fu ranks, and I could never get it to build
[20:30:08] <cradek> stuff that was made to plug into a parport, but that you want to work better or expand on a bit, is one of the places where a 5i25 shines
[20:30:10] <somenewguy> grabbed the PPA, up and running in an hour, it took a while to isntall
[20:31:06] <somenewguy> well my thing is I have a LPT running the gecko, but the digital output circuits are fried, like that when I got it
[20:31:26] <somenewguy> I can't decide if its smarter to add a secodn lpt and a buffer b oard and have more IO than I'll ever need on this machine, or just buy a new working gecko mobo

[20:32:09] <somenewguy> I want to build a full second mill in the near future, so I don't want to plan on scavanging parts from this one, I want to keep em both working at hte same time, which is rare for my projects lol
[20:32:14] <somenewguy> I do a little too much scavanging sometimes
[20:33:03] <bpuk> You can do too much scavenging?
[20:33:58] <somenewguy> yeah, if you are taking parts from still working equiptment
[20:34:16] <somenewguy> sure the new one is better when done, but if the new guy goes down, you have 0 machines
[20:34:26] <somenewguy> ...I kept having this problem with my bike arsenal
[20:34:41] <somenewguy> bent a wheel, stole good wheel from backup bike, backup bike is now uselss lol
[20:34:57] <bpuk> true. I can't speak highly enough of the mesa cards though - the difference in smoothness between a parallel port and a 5i25 is pretty noticable.
[20:35:11] <somenewguy> maybe my next weekend "2 hour projecT" will be to design and etch a damn bord for an isolator
[20:35:55] <somenewguy> whats the price point on a 5i25? I really do love spending my money on toys
[20:36:07] <somenewguy> whoever said money can't buy happiness clearly didn't ahve enough money
[20:36:28] <somenewguy> what money can't buy is a functional DIY rig lol, it can get you a pile of parts tho
[20:36:30] <cradek> somenewguy: there's a pricelist on the front page of mesanet.com
[20:39:07] <bpuk> ugh. My brain is firing now. I'm now wondering whether a downgeared 100w commercial servo would be adequate to replace the nema23 stepper. Would have to build a belt drive though

[20:47:53] <somenewguy> I was looking at mesa cards a while ago, trying to understand how I would setup my future mill and I was a little confused on servos
[20:48:12] <somenewguy> namely who does the PID heavy lifting? the main board, servo daughter board, pc etc
[20:48:26] <somenewguy> I'm sure there are many ways to skin that cat tho
[20:48:34] <CaptHindsight> somenewguy: hm2 in fpga
[20:48:48] <ssi> there's several pid loops involved with servo control
[20:48:56] <ssi> current loop, velocity loop, position loop
[20:49:08] <somenewguy> this would be teh fpga on the 5i25 or equivalent board, or on a dedicated board
[20:49:11] <ssi> depending on your drives, some of them happen in the drive and some happen in linuxcnc
[20:49:33] <somenewguy> ssi, I didn't think of that, so spoiled w/ my stepper systems
[20:49:41] <somenewguy> I udnerstand why folks love open loop
[20:49:47] <CaptHindsight> somenewguy: were you concerned about performance?
[20:49:47] <somenewguy> cause it works great till it doesent
[20:49:51] <ssi> not me, I love closed loop :)
[20:50:02] <somenewguy> ssi, me too, but it sure takes a lot of parts and brawn
[20:50:03] <CaptHindsight> I almost exclusively use servos
[20:50:07] <bpuk> on the 5i25/5i20 - depending on your drive there'll be 2-4 additional loops in there
[20:50:27] <somenewguy> heck I was thinking of adding dumb signals to my stepper driven mill, so it is only aware of stalls
[20:50:58] <somenewguy> CaptHindsight: looking at bigger mills, steppers seem to be right onth eraggedy edge trying to drive things, best to bite the bullet I figure
[20:51:05] <somenewguy> and go servo i mean
[20:51:35] <somenewguy> so I am just trying to make sure I fully understand how much silicone is needed to drive my imaginary build
[20:51:42] <somenewguy> err silicon
[20:51:57] <bpuk> for big machinery servo's are pretty much a must-have too - once you get beyond a kilowatt or so of power steppers are pretty much out of the picture

[20:52:45] <somenewguy> i'm trying to justify buying a 2ish hp 3phase vfd to drive my taig
[20:52:51] <CaptHindsight> somenewguy: also more loops in the servo amps
[20:52:53] <bpuk> that said, tuning 10+ kw servo's can be a bit hair raising :D
[20:53:11] <somenewguy> then I can buy alll this nice used equipt that needs 3phase to run that keeps popping up on CL
[20:53:30] <somenewguy> even tho the vfd would spend most its life powering a little 1/4 hp motor on my current mill
[20:53:40] <somenewguy> I like to future proof where I can
[20:54:54] <somenewguy> but from a hardware point of view, its just a PC>5i25 or similar>3 servo drive boards/vfd control
[20:55:02] <somenewguy> assuming the servo drive has encoder inputs
[20:55:27] <somenewguy> I tried to read some data sheets in the past, and they are so dense for someone who is unfamiliar w/ all the terms

[20:55:48] <bpuk> PC->5i25->7i77 - if your drives are like mine the encoders will run Encoder->Drive->7i77
[20:55:52] <somenewguy> sometimes I can't tell if they are talking about a seperate board, or a submodule on the board I am looking at etc etc and end out having 10 tabs open trying to udnerstand what I am reading
[20:56:10] <somenewguy> ok cool
[20:56:20] <somenewguy> for a while I was getting suspicious there was a 3rd link in the chain
[20:56:29] <bpuk> gah, PC->5i25->7i77->Drive (as -10 to +10v analog signals)
[20:56:57] <bpuk> you can add a 7i77ISOL between them if your drives aren't optoisolated (or if you have a lot of noise)
[20:58:59] <somenewguy> when you say "drive" on that link, what to you mean exactly?
[20:59:19] <bpuk> Drive = Servo Amp (not the servomotor )

[20:59:39] <somenewguy> ok, just finally found the 7i77 on mesa
[20:59:49] <somenewguy> I was assuming it was a amp
[21:00:38] <somenewguy> ok my brain just went full circle
[21:00:49] <somenewguy> the 7i77 is essential dumb, yes? it only translates and collates data
[21:01:26] <somenewguy> reports state of machine, lets the 5i25 act on it
[21:01:39] <bpuk> it does all the analog-digital conversion - as well as isolation and level shifting - but basically yes
[21:01:41] <somenewguy> then passes that info onto motor power control cards
[21:01:47] <somenewguy> phew
[21:01:52] * somenewguy adds that to notebook
[21:03:41] <bpuk> If you want to get really confused - mesa also do the 8i20 (which I'm saving up to buy) which is a 'dumb' amplifier - the 5i25/5i20/5i22 does all the logic

[21:08:07] <somenewguy> basicallly a VFD?
[21:08:27] <bpuk> dumber than a VFD - but for servo's rather than induction motors
[21:08:51] <somenewguy> ok so just power
[21:09:07] <CaptHindsight> I usually have matching servo amps and linear servos along with the 7i77's and 6i25
[21:09:32] <CaptHindsight> I never have trouble tuning
[21:09:54] <bpuk> matching servo's are a much better bet unless you've found an ebay bargain (in my case a kollmorgen 1.5kw servo) without a matching drive
