[00:00:32] <frank__> so i should just use the most important i/o options of the driver right? the drivers connector and options are up to 25 pins per driver, for example for positive overtravel limit, negative overtravel limit, command pulse inhibition, etc
[00:00:40] <Duc> frank_: I would be curious to see if the drives needed 14 I/O points since mine also seemed that way but alot could be eliminated
[00:01:13] <Duc> frank_: these can probably be eliminated positive overtravel limit, negative overtravel limit, command pulse inhibition, etc
[00:01:54] <andypugh> frank__: Getting a bit involved, but if you look here at a typical firmware for 5i25 + 2 x 7i85 you will see that one of the 5 RS422 channels is set aside for a smart-serial expansion card, whilst the others are step-dir generators:
http://git.linuxcnc.org/gitweb?p=hostmot2-firmware.git;a=blob;f=PIN_7I85Sx2_34.vhd;h=8fb5756afbffa7e9f5a07a45479c0a04b7f5d9df;hb=HEAD
[00:02:51] <frank__> exactly, as now, i think i have gotten it to 14, com+ com- puls1,2 sing 1,2, serv-on alarm clear (inputs of driver) alarm OA (2)OB (2) OZ (2) and Cz that i dont know whats used for (open collector output for phase z)
[00:03:12] <andypugh> So, you would send high-speed step-dir directly from the 7i85 and send other IO (at only 1kHz) via a smart-serial expansion board.
[00:03:50] <andypugh> Phase Z is encodr index.
[00:04:34] -!- chris_99 has quit [Remote host closed the connection]
[00:05:02] <frank__> yes i have phase z, phase a, phase b, _and_ a single wire phase z Open collector output of phase Z signal that says :The emitter terminal of the transistor in the output circuit is connected to the signal ground (GND) and thus not isolated.
[00:05:07] <andypugh> You may be double-counting differential pairs there. The 7i85 has + and - for each step and dir signal. That’s 2 IO, not 4 (at both ends)
[00:05:33] <frank__> lol
[00:05:38] <frank__> newbie mistake there
[00:06:56] <andypugh> Have you looked at Pico and General Mechatronics?

[01:20:59] <_methods> kenny powers spider
[01:22:46] <andypugh> I used to have a pet spider in my living room. She would wander across the room at prety much the same time each evening.
[01:23:02] <andypugh> Huge, we called her “Shelob”
[01:23:27] <_methods> was she scared of bright lights lol
[01:23:29] <andypugh> (This is for UK non-lethal values of “huge”)
[01:24:39] <andypugh> Like, 3” leg span. Pretty tiny by international standards, I suppose.

[01:29:29] <_methods> those little bastards are evil
[01:30:11] <andypugh> I quite admire ants. The only things I can’t get on with are those that lose legs easily. Like Crane Flies
[01:30:47] <_methods> ants get worse the closer you get to the equator
[01:30:58] <_methods> if you're far from it then ants are cool
[01:31:24] <renesis> theyre annoying but thats it in most of california
[01:31:25] <_methods> get close to that infernal line and ants demonic power increase exponentially
[01:31:56] <andypugh> Yes, some of the tropical ones steal cars, I hear.
[01:31:58] <renesis> we have some red ants that arent huge and dont seem to come inside

[01:32:26] <renesis> tropical bugs are fucked
[01:32:29] <_methods> yeah
[01:32:43] <_methods> those .50cal ants in the jungle are hell
[01:32:47] <andypugh> I imagine that ants in Australia are all instantly fatal, like everything else there.
[01:33:02] <_methods> they have some nasty ones there too
[01:33:34] <_methods> apparently the equator is to ants like the sun is to superman
[01:33:55] <_methods> hmmmm
[01:34:01] <_methods> maybe ants were from krypton
[01:36:02] <andypugh> They are famously good at carrying heavy weights
[01:36:28] <andypugh> So, that is the only possible explanation.
[01:37:04] <Duc> lets not forget the tiny black ants that are near impossible to kill
[01:37:53] <os1r1s> So how do you compare constant/peak torque parameters from a servo to a stepper?
[01:38:05] <os1r1s> It seems like the stepper only has one torque parameter
[01:38:49] <andypugh> If you look hard enough you can find torque / rpm plots for steppers.
[01:39:22] <andypugh> But steppers take max current at 0 rpm, regardless of load, so the peak torque is the only torque.
[01:41:44] <XXCoder> gonna love when plan dont get together :P
[01:41:56] <os1r1s> So would you say a 166 oz/in stepper was significantly higher than a constant torque 50 oz/in (350 oz/in peak torque) servo motor?
[01:42:00] <XXCoder> planned to tap alternator to clear derbis and make it run better
[01:42:05] <XXCoder> but its raining very hard
[01:42:10] <PCW> stepper motors spend most of their time pulling outwards on the rotor
[01:43:16] <andypugh> I tend to equate peak servo torque to stepper stall torque. Though whether that is reasonable depends on the exact application.
[01:44:01] <andypugh> So, that servo is (in my mind) twice as strong as the stepper at low rpm, but will move the machine a lot faster.
[01:44:50] <andypugh> In fact the torque @ rpm for servos is so much better that you can gear them down more, and still be faster and stronger.
[01:44:54] <os1r1s> andypugh I think these servo motors will go up to 4700 rpm, which would be 235 ipm on this machine. It would probably tear it apart :)
[01:45:06] <XXCoder> andypugh: encoders help too as it has built in feedback
[01:45:17] <XXCoder> it will stop at wrong position error
[01:45:39] <andypugh> feedback is also what allows the servo to run low current at low load.
[01:46:32] <andypugh> The new closed-loop stepper systems have muddied the waters though. Those look pretty good.
[01:46:38] <os1r1s> So with that said, why pull the encoder feedback into linuxcnc rather than use one of the closed loop drivers?
[01:46:51] <andypugh> They basically run as a 50-pole brushless motor.
[01:47:53] <andypugh> The best way is to run closed-loop velocity in the drive and position in LinuxCNC. Because the LinuxCNC PID knows more about what is needed than the drive does. For one thing, velocity feedforward.
[01:49:39] <Duc> so how much look ahead does linuxcnc have?
[01:50:11] <andypugh> Lots. But that’s a different question,
[01:50:31] <Duc> since that is normally a option for high speed milling on cncs
[01:50:39] <andypugh> The new TP in 2.7 has a configurable lookahead, but I think it defaults to 100segments.
[01:51:09] <andypugh> But that has little to do with where the PID should run.
[01:51:57] <os1r1s> andypugh Can you run a 60v servo at 48v?
[01:52:11] <Duc> yes but you reduce the torque valve
[01:52:14] <Duc> value
[01:52:15] <andypugh> Yes. But it will run proportionally slower
[01:52:25] <os1r1s> Got it
[01:52:34] <andypugh> The torque will be the same if drive-limited
[01:52:41] <os1r1s> And is a linear power supply vs switching relevant?
[01:53:47] <andypugh> os1r1s: For what?
[01:54:03] <os1r1s> A servo application
[01:54:11] <andypugh> For a servo power supply an unregulated supply is likely to be best.
[01:54:18] <os1r1s> Small mill size
[01:54:27] <andypugh> ie, just a transformer, rectifier and smoothing caps
[01:55:01] <andypugh> I run my mill (and the lathe I am currently converting) on simple rectified mains power.
[01:55:39] <os1r1s> Small mill or massive one :)
[01:55:51] <andypugh> But I have 400V drives, so the 320V that the mains gives when rectified is fine. It’s a source of current/charge not voltage, really.
[01:55:57] <andypugh> Mid-sized
[01:56:01] <_methods> he has 3ph
[01:56:14] <andypugh> Who has 3ph?

[01:56:31] <andypugh> No, I only have 240V single phase.
[01:56:34] <_methods> wut
[01:56:43] <andypugh> 3-phase would be nicer, certainly.
[01:56:44] <_methods> i thought all you euros had 3ph
[01:57:10] <_methods> well that sux
[01:57:13] <andypugh> No, not in domestic properties.
[01:57:17] <_methods> oh man
[01:57:25] <andypugh> Though a friend of mine has it.
[01:57:35] <_methods> so there is no upside to europe at all?
[01:57:36] <_methods> damn
[01:57:43] <andypugh> Because his house is a converted factory.
[01:57:46] <_methods> hahah
[01:57:50] <Duc> 3ph equipment is so much cheaper but rarely do people have it
[01:58:02] <_methods> all my stuff is 3ph
[01:58:06] <_methods> i just vfd it
[01:58:10] <_methods> or rpc
[01:58:17] <andypugh> Now that VFDs are so cheap 3-phase equipment is easy to run.
[01:58:22] <_methods> ^^
[01:58:34] <_methods> plz don't tell anyone that
[01:58:42] <Duc> a 15 hp rpc is cheap now days at around $1,000 ifyou dont buy stuff
[01:59:07] <Duc> build stuff

[02:00:30] <Duc> I know I removed a whole cabinet on my bridgeport mill and still have plenty of room left over
[02:00:51] <andypugh> After:
https://picasaweb.google.com/108164504656404380542/Holbrook#6216384739653615938
[02:01:17] <Duc> nice what is the cap on the top right for?
[02:01:54] <os1r1s> andypugh What MB/computer is that?
[02:02:13] <andypugh> That makes the suds pump run. No point having a VFD for a suds pump
[02:02:44] <andypugh> That’s a DN2800 that I had lying about. + 7i64, 7i49, 7i44 and 7i84.
[02:03:53] <andypugh> The DN2800 has a lot of good things, like single 12V power supply and a thin form factor. But the graphics are a real struggle with Linyux.
[02:05:28] <os1r1s> andypugh Wow, looking at the stepper torque chart it drops off dramatically after 45 IPM (with 20 TPI leadscrews)
[02:06:12] <andypugh> 20TPI is probably too fine for a practical stepper machine.
[02:06:40] <andypugh> 5mm pitch ball screws would work a lot better.
[02:06:51] <os1r1s> andypugh But more appropriate for servos?
[02:06:59] <os1r1s> Or just not appropriate at all?
[02:07:20] <andypugh> Servos would work better, but swapping screws would be cheaper.
[02:09:26] <andypugh> Running ardnary screw threads at servo speeds will wear them out. Convetional threads are really meant to be tightened once.
[02:09:48] <os1r1s> andypugh Converting this machine to ballscrews I think is a pain
[02:10:10] <andypugh> What machine?
[02:10:17] <os1r1s> andypugh Taig Mill and Sherline Lathe
[02:10:31] <andypugh> Ah, yes.
[02:10:53] <os1r1s> The sherline lathe I think is a little easier
[02:10:58] <os1r1s> The taig requires modification
[02:11:07] <andypugh> So, they are actually Acme thread rather than screw thread?
[02:11:25] <_methods> yeah you'd probably be better off doing an x2 to ballscrew
[02:11:38] <os1r1s> _methods saig x2/
[02:11:43] <_methods> i used some cheap ass chinese ballscrews on mine

[02:12:36] <_methods> the plastic caps blew out on the ballnuts lol
[02:12:51] <_methods> i tried hoggin some steel on an x2 lol

[02:13:39] <os1r1s> andypugh I'm not sure if its acme or v-thread. Trying to look now. I'm pretty sure the sherline is v-thread
[02:13:54] <_methods> it did fine till i came off the end of the part and tried to make a 90

[15:55:16] <archivist> usb is hardly solid, not sure if that is ever used in the linuxcnc environment except for hand controls
[15:55:48] <enleth> ReadError: yeah, you don't want USB
[15:56:17] <enleth> unless maybe you've got everything on USB3 and the root hub can work with USB2 emulation completely disabled
[15:56:47] <enleth> USB3 is much better when it comes to reliability, keeping timings and handling things in hardware
[16:00:06] <pcw_home> USB cannot be used for linuxCNC real time motion
[16:00:51] <pcw_home> (well its theoretically possible but reliable real time is very unlikely)
[16:09:36] <pcw_home> I would use the Ethernet card if you dont want to use a PCI or PCIE card
[16:09:40] <enleth> pcw_home: it would be interesting to try USB3, it may be capable of useful near-realtime
[16:10:01] <enleth> much more is done in hardware by the root hub

[16:10:28] <archivist> usb2 has the data rate just has a silly enumerate the devices time

[16:42:45] <archivist> description "may be incomplete", one part was removed from machine by a saw by the look of it thus making it near useless to many

[16:44:07] <ReadError> it just seems really unsmooth ;/
[16:45:28] <malcom2073> If you have high speed steppers, or need fast high mass accelerations, you're significantly better off with linuxcnc
[16:45:31] <os1r1s> Interesting. I don't have that issue with my smoothies.
[16:45:56] <ReadError> the servo drivers accept step/dir control
[16:45:58] <ReadError> I may try that
[16:46:29] <os1r1s> Linuxcnc brings a wealth of other features. But accel is a pretty basic feature that smoothie seems to do ok with.
[16:49:02] <malcom2073> ReadError: That may work, give it enough follow error that it can catch up when smoothie overshoots the acceleration
[16:49:43] <os1r1s> Anyone cnc a G0704 here?
[16:50:19] <archivist> a number have, just ask the real question
[16:52:43] <os1r1s> archivist Just curious how many people have had good success with it. And how much work was required to get it cleaned up and usable. There seem to be quite a few forum entries about unfinished parts and problems.
[16:55:55] <archivist> I think the problems show why some of us recommend getting old industrial iron
[16:57:06] <malcom2073> If you have the space, you really can't beat buying old iron
[16:57:13] <malcom2073> Space and capability or money to move it
[16:58:09] <os1r1s> archivist And more to the point, I have a fairly well equipped Taig, but am always looking at the next step up. Tormach's seem expensive and problematic. The g0704 has a lot more machining area than I expected.
[17:00:08] <archivist> all depends more on what you want to make, use the right tool for the job
[17:00:22] <_methods> doesn't that hoss guy have a 0704 build log?

[18:50:06] <FinboySlick> Nothing worth seeing. Just a chinese mill.
[18:50:54] <FinboySlick> I strongly recommend (if you take the south side) that you go there:
http://cimeaventures.com/en/ Going down the river there is a heck of a nice day.
[18:51:02] <CaptHindsight> FinboySlick: is there a mosquito season there?
[18:51:46] <FinboySlick> Well, no worse than anywhere else. That's what I liked most about the Cime Aventure thing though. None whatsoever.
[18:51:57] <FinboySlick> I'm not an outdoors kind of person.
[18:53:56] <FinboySlick> The Matapedia valley is a beautiful drive too (before you get to the Baie des Chaleurs). Winding road between mountains.

[20:51:08] -!- erve has quit [Remote host closed the connection]
[20:51:27] <enleth> as in how to determine the limits of the motor, what to look out for, what are the failure modes
[20:52:33] <enleth> I can do 3750RPM maximum on my bridgeport as is, I wonder if bumping that by 35% to a bit over 5k with the VFD is safe
[20:52:54] <enleth> assuming bearings would be OK with that
[20:53:12] <enleth> the ones I have supposedly go all the way up to 7-8k with no ill effects
[20:53:43] <enleth> The motor is 1400RPM by itself on 50Hz

[20:55:52] <enleth> the VFD can output 400Hz but I'm pretty sure the motor would end up all over the place if I tried that

[21:04:29] <rob_h> would be down to how well it is balanced, and how good the bearings are on the shaft, if its balanced and good quality it might take a bit of punishment but id not like to recomend a safe limit..
[21:04:57] <rob_h> some machine has a speed increasing gearbox, planatry gear set to double the speed etc
[21:07:17] <archivist> 35 % overspeed seems reasonable to me, listen to it and feel for vibration
[21:08:32] <archivist> I think under speed hurts motors more than over
[21:08:56] <enleth> archivist: well I feel it should be reasonable too, and 5k is starting to be in the carbide ballpark
[21:09:30] <rob_h> torque might fall off sharp tho
[21:09:36] <archivist> when very low speed they are taking more current but not going fast enough for the fan to cool them
[21:10:18] <rob_h> yea i would force air cool it if running under fixed speeds like archivist says
[21:10:42] -!- FinboySlick has quit [Quit: Leaving.]
[21:11:40] <enleth> but motors being motors, I wouldn't dismiss the posissibility of some eddy currents fuckery going on when the magnetic field is rotating faster than the motor can, heating it up like all hell or something

[21:12:57] <enleth> what I intend to say is: I know enough about motors to be aware that it's a complicated subject and I'm probably not even aware of 90% of what's happening inside one outside of the normal operating range, and I know too little to quickly catch up on the subject

[21:13:35] <archivist> back emf at high speed will reduce current and torque and probably eddy currents
[21:14:25] <enleth> good point
[21:14:26] <archivist> just that the poor thing was never designe for the mechanical stress of spinning that fast
[21:16:56] <zeeshan> enleth: hi
[21:17:01] <enleth> and that's not only a problem with bearings, right?
[21:17:05] <zeeshan> what motor is it
[21:17:32] <enleth> I mean, I can't just replace bearings with better, beefier ones designed for those speeds and expect it to be fine - it would be too easy
[21:18:08] <archivist> enleth, yes the rotating mass is a larger diameter than a high speed motor would be
[21:18:40] <enleth> zeeshan: standard 2HP Bridgeport motor, CNC version (external shaft is longer, but otherwise the same thing as manual mill 2HP motor)
[21:18:49] <zeeshan> does it have fins
[21:19:30] <enleth> what kind of fins?
[21:19:33] <Roguish> don't push the motor too fast. carbide needs a very RIGID machine, and a standard BP is not really that.

[21:20:09] <zeeshan> like that

[21:22:04] <Terlo_> this connection is making me sick,
[21:22:10] <archivist> Terlo, we have not seen a question I think
[21:22:15] <Terlo_> oh,
[21:22:23] <Terlo_> i copyed it just in case
[21:22:23] <Terlo_> hi guys, im frank, do you happen to know the difference between the mesa 7i85S and 7i85? manual difference says one has eight channel differential output and the other one is five channel RS-422 serial
[21:22:37] <enleth> zeeshan: I looked up the specs, the main bearings should be OK for up to 8kRPM. But generally bearings are the easiest thing to replace there, I think
[21:22:52] <Terlo_> i dont understand, i thought rs-422 and differential connection was the same thing
[21:23:29] <Terlo_> the board looks the same..
[21:25:32] <archivist> you can have differential signals not working to rs422, I think you are confusing standards
[21:25:44] <Roguish> enleth: are you speaking of the nameplate rpm of the motor? or the final rpm of the spindle?
[21:27:18] <Roguish> my 4 hp is 1730 on the nameplate, but the spindle goes up to double that (best case). variable vee belt and gearbox drive train.
[21:28:56] <Terlo_> okey, the manual says the encoder outputs are differential and in () says they are rs422 equivalent
[21:29:55] <Terlo_> and the input pulse train (position control) says : Differential input; parameter-selectable (1) Positive/Negative 2) Phase A/Phase B 3) Command/Direction)
[21:30:21] <Terlo_> im guessing im gonna need the 7i85S right? with the 8 channel diff outputs?
[21:30:24] <enleth> Roguish: 1400something on the nameplate
[21:30:31] <enleth> Roguish: the drivetrain can double that
[21:30:52] <Terlo_> im talking about the servo driver
[21:30:55] <enleth> Roguish: so the final max RPM is about 3750
[21:32:40] <Roguish> ok, just remember to consider everything in the drive train, not just the motor. also, read the vfd manual carefully before purchasing the vfd. make sure it all works together. (from a lesson learned the hard way...)
[21:32:58] <Roguish> and good luck.
[21:34:08] <enleth> Roguish: on the other hand, the drivetrain needs a very serious overhaul because the motor shaft is out of round and gouged from wear in a few spots, belt pulleys are also out of factory geometry
[21:34:36] <enleth> so while it's definitely not safe to overdrive it, I can try it for fun when I get replacement parts
[21:35:10] <zeeshan> if it makes you feel any better
[21:35:14] <zeeshan> i run my mikron motor from the rated 50hz
[21:35:17] <zeeshan> at 150hz.
[21:35:24] <zeeshan> and have been doing this for a long time
[21:35:36] <zeeshan> but i have not exceeded the total rpm of the spindle
[21:37:03] <enleth> oh, the other thing I could try is a pneumatic spindle speeder, right?

[22:01:45] <Roguish> enleth: good call. go slow and easy, and don't blow anything up. personally I stop and tell myself 'don't be stupid' quite often. saves on frustration, busted knuckles, and money.

[22:32:11] <C_P-Away> Sup...
[22:36:11] <malcom2073> Hi
[22:37:27] <malcom2073> Roguish: Yeah, I've always heard that most motors, especially the 1700rpm kind can be spun twice as fast (since they use similar stuff for the 1.8 and 3.6 motors), but the spindle on the other hand...
[22:37:43] <malcom2073> I plan on underdriving my varidrive, then overdriving the motor to give me more torque through a wider range, but still can't take the spindle over 4k
[23:01:31] <enleth> malcom2073: what's actually going to break first if you did?
[23:03:25] <malcom2073> I don't really know, first guess would be the varidrive belt melting, it gets really hot as is
[23:06:04] <malcom2073> I would assume the bearings are good to a good percentage higher than they run at, but who knows how worn out they are
[23:11:02] C_P-Away is now known as Contract_Pilot
[23:11:11] <Contract_Pilot> Got my other mesa card today
