12:12 AM roycroft: i've put a temporary cover on the mini-router controller cabinet, and have determined that i'm getting good airflow through both the exhaust ports in the rear
12:28 AM xxcoder: thats good. you dont want it toasty
12:28 AM roycroft: i was going to put two fans in the cabinet, but later thought that on would suffice, and it does
12:28 AM xxcoder: hmm wonder if should keep one in case, and make it manual control
12:28 AM roycroft: i think it will be fine as is
12:28 AM roycroft: i located the rpi and mesa board in front of one of the exhausts, and the drivers in front of the other one
01:00 AM Deejay: moin
04:20 AM Tom_L: morning
05:56 AM JT-Cave: gompappy sure does have a lot of issues it seems like 20 emails a day on the dev list
06:25 AM lcnc-relay: <travis_farmer@> Morning
08:23 AM pere: <URL: http://linuxcnc.org/2025/07/12/Linuxcnc-2025-Norway/ > :)
08:33 AM Tom_L: looks like a good meeting was had
10:17 AM lcnc-relay: <skunkworks8841@> neat!
10:20 AM lcnc-relay: <skunkworks8841@> JT-Cave: thanks!
10:36 AM roycroft: hi folks
10:36 AM roycroft: i got up really early this morning, and i got my e-stop wiring done
10:37 AM roycroft: the e-stop works fine, and i have powered up the motion control psu
10:37 AM roycroft: i just have to wire up the spindle psu, and then all the power/control wiring will be done, and i can start on the signal wiring
10:40 AM lcnc-relay: <skunkworks8841@> cool!
10:40 AM roycroft: yeah
10:40 AM roycroft: progress is good
10:41 AM roycroft: i still haven't mounted the spindle controller board - it's the last component to mount - but i got the threaded inserts i need for that while i was at fair, so i should be able to get that done today as well
10:41 AM roycroft: along with the spindle psu wiring
10:42 AM roycroft: but then come the soldered cables, so progress will slow down quite a bit
10:42 AM rdtsc-w: measure twice, cut once
10:42 AM roycroft: i don't measure at all for wiring
10:43 AM roycroft: but i do a lot of cut twice
10:43 AM roycroft: i generally pull wire roughly along its installed route, pull a bit extra, then cut it off the spool
10:43 AM roycroft: then i terminate one end and attach it, route it neatly to the other end, and determine where to cut to length
10:44 AM roycroft: that's slightly wasteful, but my trimmings are usually 100mm or less in length
10:44 AM roycroft: so not super wasteful
11:08 AM roycroft: are there any shielding/grounding experts here, or at least some who have a fair amount of experience with shielding?
11:09 AM roycroft: i've read some articles that say that a floating shield can be effective at "neutralizing" some of the emf emitted by its internal conductors, and some that say a floating shield is utterly useless
11:10 AM roycroft: for me to tie all the shields together in my controller would be a significant task
11:10 AM roycroft: even if i'm only grounding one end
11:11 AM roycroft: and as well, if i do not do so up front i would essentially have to toss all my shielded cables and remake them if i later determine that tying the shields together is necessary
11:11 AM roycroft: does anyone have any thoughts on that, from a practical point of view?
11:12 AM roycroft: it would be really nice, as an aside, if cable manufacturers would run copper shielding wires in their cables instead of steel
11:12 AM roycroft: soldering those wires would be much easire
11:12 AM roycroft: easier
11:13 AM lcnc-relay: <roguish> https://jauriarts.org/_heisenbridge/media/matrix.org/wNtMQZMmSSPlfvXlBgAZgdEO/tgLgCH66KaY/image.png
11:14 AM lcnc-relay: <roguish> roycroft: I put one of these in my cabinet, and run all the grounds to it.....
11:14 AM roycroft: sure, so to do that i need to cut my expensive shielded cable like 500mm longer than otherwise necessary just so i can pull the shield wire to the ground bus
11:15 AM roycroft: that's the issue - it's hard to solder the shield wires
11:15 AM lcnc-relay: <roguish> ground loops are bad
11:15 AM roycroft: i'm not concerned about ground loops
11:15 AM roycroft: things that need to be grounded are grounded - i have a grounding bus in my cabinet
11:15 AM roycroft: it's emf shielding that i'm addressing now
11:16 AM roycroft: and yes, that's a form of a ground loop as well, sort of
11:16 AM roycroft: one wants a 0v potential difference between the emf emitters and emf receptors
11:16 AM rdtsc-w: it's a ground-loop if both ends are grounded and there is current flowing through the shield
11:16 AM roycroft: well, between their shields
11:17 AM rdtsc-w: can't ground-loop if only one end is grounded
11:17 AM lcnc-relay: <.le_potato@> dont do ground loop
11:17 AM roycroft: for current-carrying wires, yes
11:17 AM rdtsc-w: for shields
11:17 AM roycroft: but a shield is supposed to absorb emf, and that is its source of current
11:18 AM roycroft: it's an inductive current path
11:18 AM rdtsc-w: once went to a cust site, powerhouse PC not communicating with compressor - it was ground-loop noise because the installer grounded both ends of the shield
11:18 AM roycroft: i do not see how grounding both ends of a shield would be useful vs grounding one end
11:19 AM rdtsc-w: solution was to un-ground one end of the shield - poof, worked
11:20 AM * roycroft is getting confused now, because he's reading what seems to be contradictory statements and agrees with all of them :)
11:20 AM rdtsc-w: likely it will just work fine (without shield grounds) but if you do ground the shield, only ground one end of it, not both ends
11:20 AM roycroft: i think i'm misinterpreting
11:20 AM roycroft: yes
11:21 AM roycroft: i'm pretty clear that shield grounding should be single-ended
11:21 AM roycroft: shielding is never supposed to carry active circuit current
11:21 AM roycroft: and if it floats at one end it never can
11:22 AM roycroft: but the original question was whether a completely floating shield would be effective, at least to some degree
11:22 AM roycroft: less effective, likely, than single-ended grounding
11:22 AM roycroft: but is it worth doing at all?
11:22 AM roycroft: twisted pair cables are extremely effective at emf suppression without a shield
11:23 AM roycroft: so i know emf can be suppressed without a common ground plane for everything
11:24 AM rdtsc-w: ground is "simple" except when high frequencies come into play (digital data, fast switching of motors)
11:24 AM rdtsc-w: No shield = worst, shield but ungrounded = likely half-effective, single-ended-grounded shield = best
11:24 AM rdtsc-w: twisted-pair will help
11:25 AM roycroft: i'm not even sure how much of a problem emf would be anyway - when i got this machine it had flat, unshielded cables to all the stepper motors and the spindle, and i installed those same flat cables from the mesa board to the drivers
11:25 AM rdtsc-w: confusingly, this is "EM" interference - there is an electrical and a magnetic component to it
11:25 AM roycroft: and while i did not do any real analysis, it seemed to work fine - i can control all the motors just fine without any obvious interference problems
11:26 AM roycroft: yes, it's inductive
11:26 AM roycroft: because of the magnetic component - i get that
11:26 AM rdtsc-w: it likely will be just fine. twist is better for one, and shield better for the other - but forget which is which atm
11:27 AM rdtsc-w: short runs, relatively low voltages = not a lot to worry about
11:27 AM lcnc-relay: <skunkworks8841@> I can just go by my experience. I ground one end of all shielded cable. Usually soldering a pig tail on one end and running it to my ground bar.
11:27 AM Rab: I can't claim to be an expert on grounding--it's an exalted title, to be sure--but I'm in the camp of ungrounded shielding is pointless, and potentially (har har) worse than nothing if it re-radiates capacitively coupled noise.
11:28 AM lcnc-relay: <skunkworks8841@> Have had really good luck with no odd noise issues
11:28 AM roycroft: that's why i said "at least with some experience ...", or similar
11:29 AM roycroft: if i waited for bona-fide experts for all my answers i would rarely get an answer :)
11:29 AM lcnc-relay: <roguish> skunkworks8841@: ditto to skunkworks
11:29 AM Rab: With steel or aluminum shielding that's difficult to solder, I crimp a little piece of brass tube, a ferrule, or other fitting to attach a piece of hookup wire I can run to the ground point.
11:29 AM lcnc-relay: <roguish> it's a bit of a PITA to do it all, but it pays off in the long term
11:29 AM roycroft: hmm, that might be a way to do it
11:30 AM roycroft: this, again, is a very small machine
11:30 AM Rab: Sometimes it's a shame to lose several inches of expensive cable just to free up some slack in the drain wire.
11:30 AM roycroft: the machine was gifted to me, but i already have much more money invested in the controller than the machine originally cost
11:31 AM roycroft: which i don't mind, but given how small the machine is, there's only so much investment of time and money that makes sense when building the controller
11:31 AM roycroft: and i'm trying to determine whether i get a real roi if invest the time in tying all the shields together
11:31 AM rdtsc-w: just don't run the motor wires near the digital wires, should be fine
11:31 AM roycroft: i'm already isolating the mains wires from any signal wires
11:32 AM roycroft: and yes, the motor wires will have a different path than the signal wires
11:32 AM rdtsc-w: looking forward to some (tiny) chips :)
11:32 AM roycroft: and my design is that the motor wires will be run perpendicular to the signal wires in the controller cabinet
11:32 AM lcnc-relay: <roguish> definitely should keep low voltage signal wires away from other noisy stuff
11:32 AM Rab: Agreed that you only ground one end.
11:33 AM lcnc-relay: <roguish> roycroft: that helps, they can cross perpendicular ok
11:33 AM roycroft: https://roycroft.us/MiniRouter/Wiring1.jpeg
11:33 AM roycroft: so look at that
11:33 AM roycroft: the drivers are on the right rear, of course
11:33 AM roycroft: the motor wires will go from the drivers to the rear of the cabinet
11:33 AM roycroft: the signal wires will go from the drives to the mesa board on the left side
11:33 AM lcnc-relay: <roguish> looks good so far
11:33 AM JT-Cave: sam your thcad2 is on the way
11:34 AM roycroft: mains come in from the front, and driver power goes out the back
11:34 AM lcnc-relay: <skunkworks8841@> JT-Cave: thanks again!
11:34 AM JT-Cave: the power supply is crooked LOL
11:34 AM JT-Cave: your welcom
11:34 AM roycroft: so even mains and motor power have separate, mostly isolated paths
11:34 AM JT-Cave: e
11:34 AM lcnc-relay: <skunkworks8841@> I stole mine from the plasma for the monarch
11:34 AM roycroft: not any more, jt-cave
11:34 AM roycroft: the left psu was not mounted in that picture
11:34 AM roycroft: the right psu was mounted, and was slightly crooked
11:35 AM JT-Cave: I didn't think so, but had to...
11:35 AM roycroft: it bugged me, so i remounted it :)
11:35 AM JT-Cave: :)
11:35 AM roycroft: i'm still a day away from starting work with the shielded cables, so i'll ponder how i might reasonably tie the shields together
11:36 AM roycroft: the idea of crimping something on the end of the steel wire is good
11:36 AM lcnc-relay: <roguish> JT-Cave: how was the ride
11:36 AM roycroft: i really do not want to try to solder on steel - it's very difficult and does not work well
11:36 AM lcnc-relay: <roguish> roycroft: that's what flux is for
11:36 AM JT-Cave: short this morning, mrs went for a walk and was pooped out after one lap at the park
11:36 AM roycroft: two days, actually, as i'm going into town tomorrow after work
11:37 AM roycroft: it is still difficult, even with flux
11:37 AM roycroft: at least for me
11:37 AM roycroft: copper or tinned copper is much easier
11:37 AM lcnc-relay: <roguish> JT-Cave: I got my 35 in yesterday..... a couple of advil PM before bed last night......
11:38 AM Rab: roycroft, where is the shielded wire going?
11:38 AM JT-Cave: I carry 2 liters of water so my ride is limited to how fast I drink the water
11:40 AM roycroft: rab: from the mesa board to the drivers, and from the drivers to the back panel connectors
11:40 AM roycroft: and then i'll run shielded cables from the back panel to the machine
11:41 AM rdtsc-w: JT, once brought a packet of some kind of protein-energy-booster stuff, and tried to consume that with water on a ride... never again lol craaaaaaamps
11:43 AM lcnc-relay: <roguish> rdtsc-w: gatorade works good.
11:43 AM roycroft: https://roycroft.us/MiniRouter/Wiring2.jpeg
11:43 AM lcnc-relay: <roguish> try Hammer Gel
11:43 AM roycroft: that's where i am now
11:43 AM roycroft: with the new power distrubution blocks, which i like a lot better
11:44 AM lcnc-relay: <roguish> roycroft: fricking labels on all the wires.....
11:44 AM roycroft: i'll be tidying things up more after i get all the power runs done
11:44 AM lcnc-relay: <roguish> a bit anal
11:44 AM roycroft: roguish: i am old and my brain does not work as well as it used to
11:44 AM roycroft: i like having all the help i can get
11:45 AM roycroft: when i have to open that thing up in a year to do something, those labels will help a lot
11:45 AM roycroft: you can see the flat cables that came with the machine, and it seemed to work fine with them
11:46 AM roycroft: and yes, i am using zip ties
11:47 AM roycroft: i hate them with a passion
11:47 AM Rab: roycroft, do the drivers have ground tie points?
11:47 AM roycroft: but i just was not up to lacing all the cables up - that is heaps of work
11:48 AM roycroft: no, but i might be able to use the mounting holes as ground ties, if you think it's important to do that
11:48 AM roycroft: i could scrape a bit of the anodizing off and screw down a ring terminal at the mount point
11:49 AM Rab: Well, after deciding to ground on end of the shield, the next questions are which end, and where, which can be deceptively complex.
11:49 AM Rab: s/on/one
11:50 AM roycroft: i get the strong impression from what i've read about grounding is that tying the shields together at the far side from the active components is best
11:50 AM roycroft: i don't know why, but that is what most folks say
11:51 AM roycroft: but i'm very open to other insights
11:51 AM roycroft: that's why i'm asking
11:52 AM roycroft: and even though this is a very small machine, and emf suppression techniques likely much less consequential than on larger machines, learning how to do it right for this translates to doing it right when i build bigger machines
11:52 AM roycroft: so to a degree, it's worth whatever it takes to do it right, even if it doesn't much matter on this particular controller
11:53 AM xxcoder: nic3e
11:53 AM xxcoder: good quite warm morning
11:53 AM Rab: I think a general rule of thumb is to negate EMI by coupling it back to a ground reference at the source of the EMI. So shielded cables to the motors would ideally connect the shield to a ground point at the drivers, or failing that, to a ground point at the output of the PSU.
11:54 AM Rab: Some systems use the philosophy of star grounding everything to a single point, often at the power entry module.
11:55 AM roycroft: i did not, as you might note, shield the driver power wires
11:55 AM roycroft: it's dc, and the psu is right next to them
11:55 AM roycroft: i did not expect there to be any appreciable emf from that
11:55 AM Rab: I think it depends on the EMI scenario you're trying to prevent. Interference between elements internal to the box? Interference to sensitive equipment outside and possibly coupled to the box?
11:56 AM roycroft: the former
11:56 AM rdtsc-w: drives *can* create electrical noise on their power inputs, but most are designed to not create much and only start offending as they (capacitors) age
11:56 AM roycroft: the only equipment ourside the box that will be near the box is the router itself
11:57 AM roycroft: and most of the cables to that will be relatively high voltage
11:57 AM Rab: EMI can absolutely manifest on the driver power rails, either through coupling or through current draw spikes if the drivers don't have adequate bulk capacitance on board.
11:58 AM roycroft: which these might not, as they are really cheap drivers
11:58 AM roycroft: i wanted to try what i got with the machine before investing in higher end drivers like geckos
11:58 AM rdtsc-w: if you discover they create input power noise, adding a simple 0.1uF 200V polypropylene cap at each one will "squelch" most of that noise
11:59 AM roycroft: but i think you're saying here that if there is emi on the power wires it will likely be generated by the drivers, not the psu itself
11:59 AM Rab: It's a really simple box with a reasonable layout and very short runs, I think there's probably no value in overthinking the wiring unless there's flakiness down the line.
11:59 AM rdtsc-w: right, typically the PSU has lots of output capacitors, so makes little relative noise
11:59 AM roycroft: rab: yes, for the most part
12:00 PM rdtsc-w: at least now - when it ages, it may produce more - but that's far down the road
12:00 PM Rab: roycroft, both sources are possible. Cheap SMPSs are notorious for poor regulation and noise on the outputs.
12:00 PM roycroft: the overthinking, as i indicated a short while ago, is for me to learn how to do it really well, so i can translate that to other builds going forward, where things might be mroe complex
12:00 PM roycroft: ok
12:01 PM rdtsc-w: the cheap PSUs often use cheap capacitors, which tend to have a shorter lifespan than name-brand parts
12:01 PM roycroft: and the spindle psu is definitely what i would call one of the "cheaper" ones
12:01 PM roycroft: the motion control psu is a meanwell, which i would consider a "high end cheaper" one
12:03 PM Rab: Mean Well has turned out to be a surprisingly good performer for the buck, over the years. It's not like TDK Lambda or whatever, but I feel good about using MW vs unbranded mystery meat SMPS.
12:04 PM roycroft: it might be interesting to run the output of each psu to a 'scope to see how clean the dc power is
12:04 PM rdtsc-w: they're economical and use inexpensive parts, but do tend to vet their capacitors and avoid the worst manufactureres
12:04 PM rdtsc-w: wouldn't hurt RC
12:04 PM Rab: I suspect there are MW clones out there since it's really easy to fake a sticker, but I can't substantiate that.
12:04 PM roycroft: i've had good luck with meanwell over the years - i have at least a dozen of their psus and none have failed or underperformed
12:05 PM rdtsc-w: they're the Bambu-Lab of power supplies? :)
12:05 PM roycroft: there are, rab, and i've gotten some, but although it's easy to clone a sticker, it's hard to make it look like a genuine one when you're using crappy components
12:05 PM roycroft: it's easy to spot the clones
12:05 PM roycroft: usually the thickness of the sheet metal is a dead give-away
12:06 PM roycroft: or should i say the thinness
12:06 PM roycroft: when you make the enclosure out of 2 layers of tin foil it's hard to make it look real
12:06 PM roycroft: i send back obvious clones
12:07 PM roycroft: and let's use the appropriate term for them
12:07 PM roycroft: they're not clones
12:07 PM roycroft: they're counterfeits
12:07 PM roycroft: if they have a sticker that says "meenwell" then one could argue that they are clones
12:07 PM xxcoder: is sticker thicker than sheet metal?
12:07 PM roycroft: but if they claim to be meanwell and they're not then they are counterfeits
12:07 PM roycroft: that's about how it is, xxcoder
12:07 PM xxcoder: fun.
12:08 PM roycroft: if you're worried that if you remove the sticker it will affect the structural integrity of the chassis, then there's a good chance it's not the real deal
12:08 PM xxcoder: lol structual sticker. indeed
12:08 PM lcnc-relay: <.le_potato@> how should i use my frequency controller with linuxcnc?
12:09 PM lcnc-relay: <.le_potato@> https://media.discordapp.net/attachments/970073761770512384/1394724770968240178/09FC362E-C64F-4C67-827B-73C35CD61197.png?ex=6877da2a&is=687688aa&hm=92c89f06da1b80c3bfd69b8ba23a39c417b31cecf847ece7f7783b531d9a8d91&=&format=webp&quality=lossless
12:09 PM roycroft: .le_potato@ : if you could post shorter urls that would really help, thanks
12:10 PM lcnc-relay: <.le_potato@> that what discord gives :3
12:10 PM roycroft: some of us use a text-based irc client, and we cannot just click on the url
12:10 PM JT-Shop: I have determined with empirical evidence that it's much more cost effective to place the package to be shipped in the vehicle before driving to town
12:10 PM roycroft: you could use a url shortener
12:10 PM roycroft: you can't just ask scotty to beam it over?
12:10 PM lcnc-relay: <.le_potato@> i just setup a host for it
12:11 PM roycroft: thanks
12:11 PM roycroft: that was not a demand or complaint
12:11 PM roycroft: just a point of information
12:11 PM Rab: I also suspect some Chinese brands have State sponsorship, and the CCP comes down on anybody trying to pollute the brand. But I don't really know how it works. The cheap and niche stuff seems like a free-for-all, but reputable brands do emerge.
12:11 PM roycroft: when i see a long url like that, unless i feel a compelling reason to browse it, i generally don't go to the effort to cut and paste and clean it up
12:12 PM lcnc-relay: <.le_potato@> https://prnt.sc/BpJYkD_67Xmc
12:12 PM roycroft: indeed, rab
12:12 PM xxcoder: roy it cant be shortened sadly
12:12 PM lcnc-relay: <.le_potato@> good? :p
12:12 PM roycroft: thank you, .le_potato@
12:13 PM roycroft: it can, xxcoder, with a url shortener such as .le_potato@ just used, but perhaps not directly
12:13 PM roycroft: which would be a shortcoming of discord
12:14 PM xxcoder: directly is what I meant yes. direct embed would be better, but theres weird stuff that cause "echo" which is annoying
12:14 PM Rab: I can click on URLs, but I think that's a function of gnome-terminal and not irssi.
12:14 PM xxcoder: ie if person pastes image then type text, then send it, it would be sent twice
12:14 PM rdtsc-w: .le_potato: S1 and S2 forward and reverse, CN2 V=0-10V for speed control? lots of ways it could be connected
12:14 PM roycroft: there were a bunch of counterfeit huanyang vfds on the market a while back
12:14 PM JT-Shop: better to just use a pasteboard for images to share here
12:14 PM roycroft: they are mostly gone now
12:15 PM roycroft: i suspect the chinese government cracked down on them
12:15 PM xxcoder: roy there was recent post about vfd burning in millenium mill project discord. insane
12:15 PM lcnc-relay: <.le_potato@> rdtsc-w, can do source control on 7i95t?
12:15 PM roycroft: i've always made sure to order mine directly through huan yang - they have an amazon store, so it's easy to do so
12:16 PM rdtsc-w: good question; what does its manual say? using 7c80 here
12:17 PM Rab: roycroft, I've been buying 220V-to-380V inverter VFDs for my Deckel mill, and it's comical how confused that niche is. Bunches of different brand names, many minor physical variants of obviously the same products. Cosmetically different VFDs come with the same firmware and printed manuals.
12:17 PM roycroft: my biggest problem with the long urls, which might be unique to my irc client, is that continued lines (>80 chars) are preceded with a "+" character
12:17 PM lcnc-relay: <.le_potato@> Rab, if you in EU. Don't buy, I send you one.
12:17 PM roycroft: so when i cut and paste a multi-line url i have to remove the embedded +s before i can browse the url
12:17 PM Rab: .le_potato, thanks! I'm in the USA.
12:18 PM lcnc-relay: <.le_potato@> if you guys need tools... just ask me
12:18 PM roycroft: which is why i don't bother most of the time unless i have a compelling reason to do so - it's actual work to do it
12:18 PM rdtsc-w: There are at least a dozen off-brand versions of Yaskawa
12:18 PM Rab: If you have access to Deckel parts, it might be worth the extra shipping to me. ;)
12:19 PM roycroft: i've had good luck with huan yang, but i've always been careful to get authentic ones
12:19 PM lcnc-relay: <.le_potato@> i mean, milling tools :p
12:19 PM roycroft: they have a good price point for me, and the only time one has ever failed was when a motor attached to it shorted out under full power
12:19 PM Rab: Discussion of HY is banned on the Practical Machinist VFD forum.
12:19 PM lcnc-relay: <.le_potato@> rdtsc-w it just shows OUT0- and OUT0+
12:19 PM lcnc-relay: <.le_potato@> that means its connects together?
12:19 PM roycroft: why?
12:20 PM Rab: Considered low quality, unprofessional, annoying to troubleshoot, and of course PM are crusty snobs.
12:20 PM roycroft: i can think of two reasons for that, neither of which are valid to me
12:21 PM roycroft: the crusty snob part fits one of the reasons
12:21 PM roycroft: the two reasons that came to my mind immediately are folks who never used them assuming they are crap because they are chinese, and folks who refuse to use them because they are chinese, whether they are crap or not
12:22 PM roycroft: i guess the snob factor falls into both categories
12:22 PM * roycroft really does not understand that
12:22 PM roycroft: i am still trying to sell my gtaw welder, and i get a *lot* of pushback from prospective buyers because it is not "american made"
12:23 PM lcnc-relay: <.le_potato@> rdtsc-w if i connect S1 and S5 together?
12:23 PM Rab: I think it's also to head off discussion loops like, "I need a VFD"Buy this $500 WEG VFD, it works great in my commercial shop" "OK, I bought this $70 HY VFD instead and it doesn't work, help me"
12:24 PM roycroft: it's an everlast, and yes, it's made in china
12:24 PM rdtsc-w: .le_potato looking at https://www.mesanet.com/pdf/parallel/7i95tman.pdf it looks like OUT0 is a digital output
12:24 PM roycroft: the snobs tell me they'll only buy lincoln or miller, because they're "made in usa"
12:24 PM roycroft: but you know what?
12:24 PM lcnc-relay: <.le_potato@> it says, high current output
12:24 PM roycroft: all the lincon and miller inverter welders are made in china
12:24 PM roycroft: likely in the same factories that make everlast
12:24 PM lcnc-relay: <.le_potato@> without schematic i can't read that manual...
12:25 PM roycroft: and everlast use high quality german-made igbts for their output, which lincoln and miller don't
12:25 PM lcnc-relay: <.le_potato@> https://prnt.sc/yunr1h5bL4G-
12:25 PM lcnc-relay: <.le_potato@> its have high current negative and positive output?
12:25 PM roycroft: i had a guy offer me $200 for it because it's "cheap chinese crap"
12:27 PM roycroft: i am a "buy american" person, and will pay more for us-made products, but 1. many products are just not manufactured here, period, and 2. i'm not willing to pay 4-10x as much for us-made when the imported product works well
12:27 PM Rab: I think it's true that a lot of the cheap Chinese stuff is not very good, and not appropriate for an industrial setting.
12:27 PM roycroft: absolutely
12:27 PM rdtsc-w: .le_potato the mesa card outputs are MOSFETs, which means it is like a switch, except that they have a polarity. positive must be wired to the more positive terminal for correct operation. Then when it closes, it closes like a switch.
12:27 PM roycroft: the chinese make what their customers want
12:28 PM Rab: I would use a Mean Well power supply, but I wouldn't resell it to someone as part of a larger solution I had to support.
12:28 PM roycroft: and if their customer is wal*mart the customer wants the cheapest price possible
12:28 PM roycroft: so they make crappy quality stuff for a low price
12:28 PM lcnc-relay: <.le_potato@> rdtsc-w so its source control?
12:28 PM pcw--home: S1 --> OUT0+ --> OUT0- --> SC S2 --> OUT1+ --> OUT1- --> SC
12:28 PM roycroft: but they also know how to make high quality products
12:28 PM roycroft: they just cost more
12:28 PM pcw--home: FWD and REV
12:29 PM roycroft: i usually strike a compromise that works for me
12:29 PM roycroft: and yes, if i were reselling to a customer and had to provide support, that would affect the compromise conditions significantly
12:30 PM lcnc-relay: <.le_potato@> thank you pcw--home
12:30 PM rdtsc-w: thanks pcw... note that AC drive has devicenet input - there might be some way to interface to that (unsure)
12:31 PM roycroft: and regarding spindle control, i was wrestling with my controller wanting 0-10v for external speed control, and how to get that voltage to it while being able to control it with the mesa board
12:32 PM roycroft: but it just occured to me (well, over the weekend), that there is an on-board jst connector for a rheostat that provides 0-5v
12:32 PM roycroft: if i connect the mesa board to that i can provide the voltage from the mesa board, and not use the on-board 5v
12:33 PM roycroft: i think that will work - i just connect 2 wires to the jst connector instead of 3
12:33 PM lcnc-relay: <.le_potato@> should work with pwm?
12:33 PM lcnc-relay: <.le_potato@> or over rs232
12:33 PM roycroft: it's odd that it works with 0-5v onboard but requires 0-10v for external control
12:34 PM roycroft: seems it would be easier to stick with 5v for both
12:34 PM xxcoder: is there a way to double voltage?
12:34 PM xxcoder: ie input 2v output 4v
12:34 PM xxcoder: 5 to 10, etc
12:36 PM roycroft: yes, but that would require an additional component
12:36 PM roycroft: if i can just make the mesa board look like a rheostat to the spindle controller and use the jst connector i can do it with 5v
12:36 PM roycroft: without anything extra
12:37 PM * roycroft thinks it will work, but isn't at that point in the build yet
12:38 PM lcnc-relay: <.le_potato@> how my VFD can work closed loop if no input?
12:39 PM lcnc-relay: <.le_potato@> there is even vibration correction, wierd things
12:40 PM xxcoder: interesting. I wonder what it corrects specifically, from vibration
12:41 PM Rab: .le_potato, it analyzes current draw and inductive kickback from the motor.
12:42 PM lcnc-relay: <.le_potato@> yes, i see the same
12:42 PM lcnc-relay: <.le_potato@> same like RC 3 phase controllers
12:42 PM Rab: right
12:42 PM lcnc-relay: <.le_potato@> there is so complicated PID control for it
12:43 PM Rab: It's not as effective as a separate active feedback sensor, but it works well enough for a lot of applications.
12:43 PM lcnc-relay: <.le_potato@> rs232 communication looks pretty decent
12:44 PM lcnc-relay: <.le_potato@> linuxcnc supports it?
12:45 PM lcnc-relay: <.le_potato@> i mean over mesaboard not with USB
12:45 PM lcnc-relay: <.le_potato@> The PrintNC project strongly recommends using your Huanyang VFD with RS485
12:45 PM lcnc-relay: <.le_potato@> everybody using this chinese vfd?
12:47 PM roycroft: far from everybody, but many people use them
12:55 PM roycroft: so on another note, i have a relay hat for my controller's rpi that has an i2c interface
12:56 PM roycroft: there is no linuxcnc support for i2c, but there are linux utils to control/monitor i2c devices
12:57 PM roycroft: is it a reasonable approach to manage the relays with shell scripts, and can hal signals be managed by shell scripts?
12:57 PM roycroft: these relays are for indicators, so they do not need real-time control
12:58 PM lcnc-relay: <skunkworks8841@> you can create scrips fired by M Gcodes. They should not be relied upon as they would not be realtime.
12:58 PM roycroft: i have two indicators that i need to control
12:58 PM roycroft: one is green, and should be on when motion control is active, and off when it is not
12:59 PM lcnc-relay: <skunkworks8841@> otherwise - you could create no-realtime hal componants in python or such that would control the devices
12:59 PM roycroft: the other is read, and should be on when there is a fault
12:59 PM roycroft: the motion control one could be done with m codes
12:59 PM roycroft: i'm not sure about the fault one, as the main condition that would fire it would be an e-stop event
01:00 PM roycroft: and as i said, real time is not a requirement
01:00 PM roycroft: as long as it's not a delay of thousands of milliseconds
01:00 PM roycroft: which i can't imagine it would ever be
01:00 PM roycroft: i'll look into doing it in python
01:01 PM roycroft: which could call the i2c-set utility
01:01 PM roycroft: thanks
01:02 PM roycroft: i'm still thinking ahead of myself a bit, but not too far - i'll need to wire up those indicators in the next couple days or so
01:02 PM roycroft: i don't need to actually control them yet, but i need to wire them in a way that i know i'll be able to control
01:03 PM roycroft: and i don't have any stand-alone relays with 5v coils
01:03 PM roycroft: hence my desire to use the hat with the odd interface
01:20 PM lcnc-relay: <.le_potato@> where do you use i2c?
01:21 PM roycroft: i have a 4 relay hat on my rpi that is controlled via an i2c interface
01:22 PM lcnc-relay: <.le_potato@> i dont know these non industrial stuffs 😦
02:07 PM JT-Shop: 310a starter works fine...
02:45 PM BorgPipe: got my dxf2gcode converter working
02:45 PM BorgPipe: https://github.com/netpipe/GCODE-Tools/blob/master/Engraver/qt-dxf2gcode/main.cpp
02:45 PM BorgPipe: just need to test now
02:46 PM BorgPipe: just does contours for now
02:47 PM Tom_L: JT-Shop, what was the issue?
02:49 PM BorgPipe is now known as NetPipe
02:58 PM roycroft: i keep reading "borgpipe" as "bongpipe"
02:58 PM roycroft: and i'm fairly sure that's what i'm not supposed to be reading
02:58 PM roycroft: but netpipe is much better
02:58 PM xxcoder: that'd be heck of adoption for borg
02:59 PM roycroft: i had to deal with work stuff at lunch today, so i'm going to take a late lunch now and get that 24v psu wired up
02:59 PM roycroft: and now there's another complication
03:00 PM roycroft: i can probe my i2c devices (the relays), but when i try to write to them i get "write failed" errors
03:00 PM roycroft: i think i have another relay hat that is a different type, so i should try to find that as well when i work on the controller
03:01 PM roycroft: who maintains the rpi distro of linuxcnc?
03:01 PM roycroft: what i thought at first is that raspi-config had been removed from the mainline distro
03:01 PM roycroft: but now i find that it's still there, but has been removed from the linuxcnc image
03:01 PM roycroft: and i'd like to know why, and ask that it be put back in the distro
03:01 PM roycroft: it's part of the base os, so it can't just be added via aptitude
03:02 PM xxcoder: wonder if thats to avoid linuxcnc breaking changes, but yeah dunno
03:02 PM roycroft: i actually had to download a copy of the git repository and peruse the script to see what it does, then i hand to manually make the changes on the rpi
03:02 PM roycroft: possible, xxcoder
03:03 PM roycroft: but at the end of the day that's on the end user
03:03 PM roycroft: leaving it there and plastering dire warnings in huge letters in the documentation would be better, imo, than removing it
03:04 PM roycroft: or, at the very least, disabling it by default with a mechanism to enable it documented in the "advanced scary stuff - you're on your own with this" section of the docs
03:04 PM xxcoder: possible. I guess would need to know why first
03:04 PM roycroft: anyway, i'm off to do that stuff, and hope the other hat works better
03:04 PM roycroft: it's frustrating that i can detect mine but not write to it
03:05 PM roycroft: it's also going to be really hard to remove without removing the entire din rail on which the rpi is mounted, and i just had to do that yesterday, and i do not want to do it again today
03:05 PM roycroft: i have to unmount several other components to do that, and i really want to avoid that much going backwards work
03:10 PM JT-Shop: Tom_L, no clue, I just took the starter out and used my jumper battery thing and a push button to test it and man was that wild
03:51 PM rdtsc-w: "we are the borg... resistance is... hey man, is that a brownie?"
03:52 PM rdtsc-w: RC, Debian12 has 'menu-config' in place of raspi-config
03:52 PM rdtsc-w: it is smaller and simpler though
03:53 PM rdtsc-w: raspbian has veered from Debian so far, it made more sense to use Debian than raspbian (likely due to RT kernel availability at the time)
04:02 PM lcnc-relay: <.le_potato@> can i connect lan direct from pc to mesa board or need switch/patch cable?
04:09 PM lcnc-relay: <ccatlett1984@> can direct connect (assuming the pc does auto-crossover, you don't even need a special cable)
04:16 PM Tom_L: i think (not positive) that pcw takes care of the crossover anyway
04:20 PM JT-Shop: crap empire is paying me for the surface grinder and I've not delivered it yet
04:24 PM JT-Shop: hmm it's only been 30 days and normally they pay in 60
04:29 PM JT-Shop: the old key switch was flaky
04:32 PM Tom_L: heh
04:32 PM Tom_L: well at least you found something
04:32 PM JT-Shop: but still don't know why it won't turn over...
04:32 PM Tom_L: still not working?
04:32 PM Tom_L: maybe a bad ground strap somewhere
04:32 PM JT-Shop: putting the starter back in after a break
04:36 PM roycroft: yay! all my power wiring is done
04:37 PM roycroft: the spindle controller board is mounted and powered up now
04:37 PM roycroft: as well as its psu
04:37 PM roycroft: i could not find my other relay hat for the rpi, though
04:37 PM roycroft: i just saw it before i left for fair, so it can't be buried too deep
04:37 PM roycroft: well, it can, but it shouldn't be
04:38 PM xxcoder: maybe someone saw it, wore it as hat and walked away ;0
04:38 PM xxcoder: ;)
04:39 PM Unterhaus__ is now known as Unterhausen
04:39 PM Unterhausen: It's amazing how fast stuff can get very lost around here.
04:40 PM JT-Shop: https://youtu.be/T0glknnQxbU?t=445
04:40 PM JT-Shop: weird plane
04:40 PM Unterhausen: I imagine my demise will be the result my head exploding because of not being able to find something I just had in my hand
04:40 PM Tom_L: kindof ironic you have a lift but you're out crawling in the weeds working on a starter :)
04:41 PM JT-Shop: well I've cleared the weeds
04:42 PM JT-Shop: better than that winter I changed the starter on the 02 cheby truck
04:42 PM JT-Shop: that sucked in the snow
04:43 PM Tom_L: i bet
04:44 PM Unterhausen: That plane looks like one of the smaller veritas bevel up or low angle planes
04:45 PM Unterhausen: except it has a reinforcement on the nose of the plane
04:47 PM roycroft: i have a pile of tools that i've been using on this
04:47 PM roycroft: and spools of wire
04:47 PM Tom_L: all powered and tested?
04:48 PM Tom_L: did you figure out your 10v for the spindle?
04:48 PM roycroft: in the old shop i had all my wire spools for smaller gage stuff organised, and hung up in a piece of pipe over a workbench, so i could just reach up and pull down what i need
04:48 PM roycroft: for this, i hand to unpack boxes and pile the spools up
04:48 PM roycroft: so when i tidy up i'll probably find the hat
04:48 PM roycroft: all tested so far, tom_l
04:48 PM roycroft: that is, everything i've wired up so far is powered up and tested
04:49 PM roycroft: i have not figured out the 10v bit, but i have a cunning plan
04:49 PM Tom_L: i used a buck reg off my 24v for it
04:49 PM roycroft: for some odd reason, the spindle controller supplies 5v to a rheostat that plugs in via a jst connector
04:49 PM Tom_L: i may have mentioned that
04:49 PM roycroft: so if i use the rheostat, i'm using onboard power, which is 5v
04:50 PM Tom_L: i think i encountered a similar situation
04:50 PM roycroft: the external power - the "mach 3" interface - is what needs 10v
04:50 PM Tom_L: :)
04:50 PM roycroft: so i'm thinking i might hook the mesa board up to the jst connector
04:50 PM xxcoder: thankfully only very little amps on that 0-10v
04:50 PM roycroft: and supply 5v that way
04:50 PM roycroft: yeah, it's milliamps
04:50 PM roycroft: the jst connector has supply, wiper, and output connections
04:51 PM roycroft: well, output is ground, i guess
04:51 PM roycroft: so if i hook the mesa board to wiper and ground i should be able to do it with 5v
04:51 PM Tom_L: supply what part of the mesa board with 5v?
04:51 PM roycroft: i think
04:51 PM roycroft: no
04:51 PM Tom_L: the analog is separate
04:51 PM roycroft: i would use the spindle contol pin on the mesa board to supply 0-5v
04:51 PM roycroft: doesn't it use field power?
04:52 PM roycroft: i am feeding 5v field power to the mesa board
04:52 PM Tom_L: i'd have to look at the pdf for that board
04:52 PM roycroft: or is it totally isolated?
04:52 PM Tom_L: mine i supplied the analog with 10v
04:52 PM roycroft: if it is, then that's still ok
04:52 PM Tom_L: i think it's likely isolated
04:52 PM roycroft: i could use the 5v from the spindle controller to feed the analog port on the mesa
04:52 PM roycroft: still use the jst connector, but split it up
04:53 PM roycroft: essentially, the mesa board is a "digital rheostat"
04:53 PM Tom_L: it's the same basic circuit on mine and the spinx board
04:53 PM Tom_L: afik
04:53 PM roycroft: so 5v from the spindle controller to analog in on the mesa
04:53 PM roycroft: analog out from the mesa to the wiper pin on the spindle controller
04:53 PM roycroft: and ground to ground
04:54 PM Tom_L: and you think a 0-5v is adequate?
04:54 PM roycroft: the built-in rheostat port uses it
04:54 PM roycroft: i measured the pins on the jst connector, and the board supplies 5v
04:55 PM roycroft: anyway, i can try that
04:55 PM roycroft: i would rather not use a voltage divider circuit
04:55 PM roycroft: that both introduces another component, and also introduces a bunch of extra heat
04:55 PM roycroft: or probably a tiny bit of extra heat in this case
04:56 PM roycroft: nevertheless, if it can be avoided i'd like to avoid it
04:56 PM roycroft: but if it's what i need to do i won't hesitate to do it
04:57 PM Tom_L: https://www.ebay.com/itm/335181965776
04:57 PM Tom_L: i used one of those off the 24v
04:57 PM roycroft: maybe instead of working on the driver signal wiring i'll wire up the spindle next
05:16 PM Tom_L: set it and put a dot of epoxy on the screw
05:16 PM roycroft: yeah, that would work
05:16 PM Tom_L: LM2596
05:16 PM roycroft: but i'm going to try my idea first
05:16 PM Tom_L: widely used for that
05:16 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/misc_stuff/5v_switcher.jpg
05:16 PM Tom_L: i made my own before i found those
05:16 PM roycroft: and besides the reasons i just gave for preferring not to use a voltage converter, if i ordered that right now it would take a few days to get here
05:16 PM roycroft: if my idea on how to do it works i may have it working tonight
05:16 PM Tom_L: worth a try
05:16 PM roycroft: yup
05:20 PM JT-Shop: for some reason there are two wires from the S terminal on the solenoid
05:20 PM JT-Shop: I wish I could find a wiring diagram for the 310a
05:21 PM Tom_L: what year?
05:22 PM JT-Shop: no clue, they only made them for a few years
05:23 PM JT-Shop: Deere 310A was made from 1976 to 1983
05:25 PM Tom_L: they'll sell you a manual for twenty bux
05:27 PM lcnc-relay: <.le_potato@> it moves!
05:27 PM lcnc-relay: <.le_potato@> somebody can give me please something wiki about drive / scale?
05:28 PM Tom_L: https://forum.linuxcnc.org/49-basic-configuration/33004-formula-to-calculate-the-right-scale
05:28 PM Tom_L: i'm sure there
05:28 PM Tom_L: s a better one
05:30 PM Tom_L: JT-Shop, see if you can DL this one: https://www.slideshare.net/fsjefkkselmd/john-deere-310-a-backhoe-loader-service-repair-manual-136084829
05:30 PM JT-Shop: gotta join...
05:32 PM Tom_L: yeah they getcha by the whoha no matter what
05:34 PM JT-Shop: hmm I need a throw away email
05:34 PM Tom_L: https://www.jensales.com/content/ppp/john-deere-service-manual-jd-s-tm1158.pdf
05:34 PM Tom_L: that was another one i found
05:36 PM Tom_L: pdf $20
05:39 PM Tom_L: might save a 'subscription'
05:41 PM Tom_L: is there a fuseable link from the battery to the 'acessories'
05:41 PM Tom_L: the starter circuit could be routed thru that
05:41 PM JT-Shop: I'm not sure
05:41 PM Tom_L: it usually just looks like a 'special' plain wire
05:43 PM Tom_L: https://www.wiringdepot.com/store/p/704-JT-T-206F-18-AWG-Red-Fusible-Link-Wire-with-5/16-Stud-1-Ft.aspx
05:43 PM Tom_L: for example
05:43 PM Tom_L: just a random one
05:45 PM JT-Shop: the 82 C3 has a fusible link wire
05:46 PM Tom_L: most cars did. hard telling how they handle it nowdays
05:46 PM Tom_L: probably one of the 26 control modules :)
05:46 PM JT-Shop: lol
05:47 PM lcnc-relay: <.le_potato@> and i have no clue what fitmware am i need
05:47 PM JT-Shop: me either
05:47 PM Tom_L: le_potato did you run mesaflash to view the current firmware configuration?
05:47 PM Tom_L: or using mesact to the same end
05:47 PM JT-Shop: Tom_L, did you see the bug fix for mesact?
05:48 PM Tom_L: no, i saw i was behind by 2 but generally that's when you move the deb
05:48 PM Tom_L: i'll check and build
05:49 PM JT-Shop: hmm did I move the deb?
05:49 PM lcnc-relay: <.le_potato@> hiw can i check?
05:49 PM Tom_L: one sec
05:49 PM Tom_L: remind me what board
05:49 PM lcnc-relay: <.le_potato@> 7i95t
05:49 PM lcnc-relay: <.le_potato@> only flash reload verify
05:50 PM JT-Shop: what are you needing that is not in the normal firmware?
05:50 PM -!- #linuxcnc mode set to +v by ChanServ
05:50 PM Tom_dev: mesaflash --device 7i95t --addr 10.10.10.10 --readhmid
05:51 PM Tom_L: run that from a terminal
05:51 PM JT-Shop: if he jumpered it for 10.10.10.10
05:51 PM Tom_L: i think he may have
05:51 PM JT-Shop: better to use mesact
05:51 PM JT-Shop: and search for a board
05:51 PM Tom_L: yeah, i'm not that versed on where you put it
05:51 PM lcnc-relay: <.le_potato@> does not show firnware wersion
05:52 PM Tom_L: le_potato did you change the IP address jumper on the mesa board?
05:52 PM lcnc-relay: <.le_potato@> yes
05:52 PM lcnc-relay: <.le_potato@> its moves the servos
05:52 PM Tom_L: for the alternate
05:52 PM Tom_L: ok
05:52 PM lcnc-relay: <.le_potato@> i can communicate with it
05:52 PM Tom_L: ^^ that should list the pinout
05:52 PM roycroft: i found my other relay module, and it's not a rpi/arduino hat
05:52 PM roycroft: it's a stand-alone module with 5vdc coils
05:52 PM lcnc-relay: <.le_potato@> pinout is good
05:53 PM Tom_L: but it tells you what config is loaded
05:53 PM Tom_L: and the pin functions
05:53 PM Tom_L: you can do the same thing with mesact i just forgot where it was in the gui
05:54 PM lcnc-relay: <.le_potato@> i did with mesact
05:54 PM Tom_L: so that is what is loaded
05:54 PM lcnc-relay: <.le_potato@> ok thats good
05:54 PM Tom_L: if you need something different there are premade files you can upload to it
05:55 PM Tom_L: using mesaflash
05:55 PM Tom_L: or using mesaflash thru mesact
05:55 PM Tom_L: whichever you prefer
05:55 PM JT-Shop: mesact can flash a bit easier than using the terminal
05:55 PM Tom_L: probably
05:56 PM Tom_L: and on the new fpga i'm not sure what the alternate file is that shows the pinout of each bit file
05:56 PM Tom_L: xml maybe?
05:56 PM Tom_L: some of the folders have those available so you can tell what the config does
05:57 PM Tom_L: i haven't looked at the 7i95t
05:57 PM lcnc-relay: <.le_potato@> i cant find what SCALE means
05:58 PM Tom_L: steps per rev usually i think
05:58 PM JT-Shop: scale is the number of pulses per user unit ie mm or inch
05:58 PM Tom_L: or unit
05:58 PM Tom_L: ie inch or mm
05:58 PM JT-Shop: unit
05:58 PM Tom_L: ok
05:58 PM lcnc-relay: <.le_potato@> that what i dont know
05:58 PM lcnc-relay: <.le_potato@> unit
05:58 PM Tom_L: i'm starting to rust
05:58 PM Tom_L: metric or inch?
05:58 PM JT-Shop: metric is 1 mm, inch is 1 inch
05:59 PM Tom_L: so how many pulses does it take to move the axis 1mm or 1"
05:59 PM Tom_L: you can measure it or calculate it
05:59 PM Tom_L: better to calculate it
06:00 PM Tom_L: that includes any microstepping
06:00 PM Tom_L: afik
06:00 PM JT-Shop: on my plasma I stared with calculated the adjusted by measuring due to belt stretch
06:00 PM lcnc-relay: <skunkworks8841@> better to calculated it then verify with measurment 🙂
06:00 PM lcnc-relay: <.le_potato@> i have it already because i had mach3 on it
06:00 PM lcnc-relay: <.le_potato@> if i dont want to use pid/linear scale
06:01 PM lcnc-relay: <.le_potato@> i just set max error to 0 or 999
06:02 PM JT-Shop: best to start with the default max error
06:02 PM Tom_L: and if it runs backward change the sign on the scale number for that axis
06:02 PM lcnc-relay: <.le_potato@> i have no encoder yet, it gives error
06:03 PM lcnc-relay: <.le_potato@> and somehow i dont see axis Y at manual control
06:03 PM * JT-Shop calls it a day before the thunder storms hit
06:03 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/CTgQCJgei41Xa4WGA
06:04 PM lcnc-relay: <skunkworks8841@> Looks like it works
06:04 PM Tom_L: JT-Shop, PR #151 mesact
06:05 PM Tom_L: skunkworks, is that on the tower?
06:05 PM lcnc-relay: <skunkworks8841@> no - just on the light pole outside the house
06:05 PM lcnc-relay: <skunkworks8841@> I thought about putting one on the tower but the ones that ran over network were $1000's of dollars
06:09 PM roycroft: if i put a cupola on my new shop roof i might mount a weather station on top of it
06:10 PM roycroft: i plan on installing a wind vane anyway if i build the cupola
06:10 PM roycroft: i might as well install one that will feed me data and add some other sensors while i'm at it
06:10 PM xxcoder: sounds fun
06:11 PM roycroft: i am vacillating right now
06:12 PM roycroft: going back and forth between deciding to work on my relay hat issue or wire up my spindle and try to see if the mesa board can control it
06:12 PM roycroft: i think i need to just go back out to the studio and start work on one of them
06:12 PM Tom_L: go for the spindle
06:13 PM Tom_L: then if you need parts you can order them
06:13 PM roycroft: i'm thinking that might be best
06:13 PM roycroft: at least i can make it move with the new controller
06:13 PM Tom_L: and if you don't it's one more off the list
06:13 PM roycroft: and that will stimulate me to keep going
06:13 PM roycroft: right, that too
06:13 PM roycroft: i'll know if i need to order parts or not
06:13 PM Tom_L: go forth and conquer
06:14 PM roycroft: the only reason i'm procrastinating on that is that it will take me some to clear off the bench to be able to solder
06:14 PM roycroft: but i need to tidy up anyway
06:14 PM lcnc-relay: <skunkworks8841@> I found my power supplies... Now I need to see how they are hooked up - I guess I didn't take a picture
06:14 PM * roycroft goes to do one of the things
06:14 PM Tom_L: skunkworks, i have pics but who knows where they are :)
06:15 PM Tom_L: those kind i usually put on the server for safe keeping
06:15 PM lcnc-relay: <skunkworks8841@> lol - everything is on google cloud.. I found about the right time period - but there is TP testing, kids, plasma and a ton of other stuff I was working on. How did I have the energy
06:16 PM lcnc-relay: <.le_potato@> looks like everything works and qtdragon gui is nice
06:17 PM xxcoder: nice!
06:28 PM lcnc-relay: <.le_potato@> i need a touchscreen
06:33 PM lcnc-relay: <.le_potato@> with microsteps its not that accurate if i want to step .01mm
07:18 PM roycroft: are you about, xxcoder?
07:18 PM xxcoder: yeah
07:19 PM lcnc-relay: <skunkworks8841@> uh oh...
07:19 PM rdtsc_ is now known as rdtsc
07:19 PM roycroft: when you wire dc circuits, do you use red or black as positive voltage?
07:19 PM lcnc-relay: <big_kevin420@> a relay hat sounds uncomfortable
07:19 PM rdtsc: red, unless you're Siemens
07:19 PM xxcoder: red as hot if I recall
07:19 PM roycroft: depends on what your brain need to relay, big_kevin420
07:19 PM roycroft: good
07:19 PM roycroft: i know what is correct
07:19 PM lcnc-relay: <.le_potato@> blue everywhere with labels
07:19 PM roycroft: i'm asking what xxcoder does :)
07:19 PM lcnc-relay: <big_kevin420@> not blue and brown?
07:20 PM roycroft: i use red and blue sometimes
07:20 PM roycroft: but the existing setup has red and black
07:20 PM lcnc-relay: <.le_potato@> just use labels
07:20 PM lcnc-relay: <skunkworks8841@> lol - we have a plasma from china that throws the color standards out..
07:20 PM roycroft: and red +, black - is correct
07:20 PM xxcoder: did I acciently switch on wiring?
07:20 PM roycroft: no, i just wanted to know
07:20 PM rdtsc: larger Siemens G120 drives have a red and black wire from the 24V psu to the lower board... black is positive
07:20 PM xxcoder: lol ok
07:20 PM roycroft: the worst case here would be that the spindle would run backwards
07:20 PM roycroft: and then i would switch
07:21 PM lcnc-relay: <big_kevin420@> look at this guy just use labels
07:21 PM lcnc-relay: <skunkworks8841@> I really want to get the heat shrink label maker...
07:21 PM roycroft: i don't have the control circuit wired up yet, but the cable from the controller to the back panel, and from the back panel to the motor are made
07:21 PM lcnc-relay: <skunkworks8841@> those look cool
07:21 PM lcnc-relay: <.le_potato@> i have :3
07:21 PM lcnc-relay: <big_kevin420@> i am gonna get one
07:21 PM roycroft: get it, skunkworks8841
07:21 PM roycroft: they are cool
07:21 PM lcnc-relay: <.le_potato@> but too complicated
07:21 PM lcnc-relay: <skunkworks8841@> I keep forgetting
07:21 PM lcnc-relay: <.le_potato@> we use label printer and put on little plastic
07:21 PM roycroft: when i got mine, i showed it off on channel and jt bought one within seconds
07:21 PM lcnc-relay: <.le_potato@> in industry
07:21 PM lcnc-relay: <big_kevin420@> i didnt steal enough labvels from work, so i only have like 3 io listed
07:22 PM roycroft: he instantly saw the value
07:22 PM roycroft: and they're not that expensive
07:22 PM lcnc-relay: <skunkworks8841@> we usually use the wire numbers and then put clear heatshrink on it. But a heat shrink printer would be awesome'
07:22 PM roycroft: https://labelworks.epson.com/printers/all-printers/lw-px700.html
07:22 PM lcnc-relay: <.le_potato@> wire numbers complicated again...
07:22 PM lcnc-relay: <big_kevin420@> ive been looking at some china ones the last few months
07:23 PM roycroft: get what i just posted
07:23 PM roycroft: seriously
07:23 PM lcnc-relay: <big_kevin420@> only if its qwerty
07:23 PM roycroft: it's the bee's knees of cable labelers
07:23 PM lcnc-relay: <big_kevin420@> fucking brady is abcdefg
07:23 PM roycroft: it is qwerty
07:23 PM xxcoder: looks very qwerty from what I see
07:23 PM lcnc-relay: <.le_potato@> for real get that plastic printer 😦
07:24 PM roycroft: most of you don't do this, probably, but one thing i really like is that i can get black on silver lables, and print bar codes on them
07:24 PM roycroft: i use that for adding serial numbers to gear that i sell
07:24 PM roycroft: looks really professional
07:24 PM roycroft: and hard to muck with
07:24 PM lcnc-relay: <big_kevin420@> hmm its 2x the price of the china one, so thats not bad
07:24 PM lcnc-relay: <big_kevin420@> i dont even want to steal one of the many extra brady ones my boss buys
07:24 PM roycroft: i recommend the deluxe kit
07:25 PM lcnc-relay: <big_kevin420@> just because its not qwerty
07:25 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/how_to/atmega168/breadboard_basic_side.jpg
07:25 PM Tom_L: i did that as a cheap alternate
07:25 PM roycroft: the case is really nice, and it comes with an ac adapter and a big magnet to hold it on the side of an equipment rack while you're working
07:25 PM lcnc-relay: <.le_potato@> i make a picture tomorrow what i have because i dont remember
07:25 PM lcnc-relay: <.le_potato@> but you put plastic/label stuff inside
07:25 PM lcnc-relay: <.le_potato@> and its print it
07:25 PM lcnc-relay: <big_kevin420@> yeah i do the shrink tube obver top also
07:26 PM lcnc-relay: <.le_potato@> i think, with laser
07:26 PM lcnc-relay: <big_kevin420@> thats why i just want a shrinktube one
07:26 PM roycroft: but now that i know how xxcoder wires things, and confirm that he does it correctly, i'm going to go play with my spindle for a bit
07:26 PM Tom_L: if i used that more i would consider one too
07:26 PM lcnc-relay: <big_kevin420@> thats why i just colour code everymachine the same
07:27 PM lcnc-relay: <big_kevin420@> and look them up every time i need
07:27 PM roycroft: i have some learning to do to before i can attempt to get the mesa card to control it, but i'm going to get it going with the rheostat right now to make sure my cables are good, then start work on the control circuit
07:27 PM lcnc-relay: <big_kevin420@> algernon style
07:27 PM roycroft: the epson has 1/8", 3/16", and 1/4" shrink tubing
07:27 PM roycroft: and i'm not sure what the shrink spec is, but i'm sure it's at least 3:1
07:27 PM roycroft: they may have even bigger shrink tubing
07:28 PM roycroft: i have my old panduit cable labeler that i use when i need to lable the outside of big cables
07:28 PM lcnc-relay: <.le_potato@> i have Dymo one
07:28 PM Tom_L: do those require special shrink tube or just regular stuff?
07:28 PM lcnc-relay: <.le_potato@> aliexpress one works perfect
07:28 PM Tom_L: the epson
07:28 PM lcnc-relay: <.le_potato@> idk
07:29 PM lcnc-relay: <big_kevin420@> fuck forgot the exchange rate
07:29 PM lcnc-relay: <big_kevin420@> back to china one
07:30 PM Tom_L: hah
07:30 PM lcnc-relay: <.le_potato@> why i have joint following error?
07:30 PM Tom_L: accel too high maybe
07:30 PM lcnc-relay: <.le_potato@> is it know without encoder?
07:30 PM lcnc-relay: <big_kevin420@> yeah
07:30 PM lcnc-relay: <big_kevin420@> using like math n shit
07:31 PM lcnc-relay: <.le_potato@> how tf if no feedback
07:31 PM lcnc-relay: <big_kevin420@> $210 loonies for the printer
07:31 PM lcnc-relay: <big_kevin420@> math
07:31 PM Tom_L: https://forum.linuxcnc.org/38-general-linuxcnc-questions/36464-joint-following-error-on-stepper-system
07:31 PM lcnc-relay: <big_kevin420@> there is feedback
07:31 PM lcnc-relay: <big_kevin420@> but not from the stepper motor
07:31 PM roycroft: https://www.fiberoptics4sale.com/products/ls8e
07:31 PM lcnc-relay: <big_kevin420@> each step is one send/onefeedback
07:31 PM roycroft: i have the older version of that for big cables
07:31 PM Tom_L: max_acceleration and stepgen_maxaccel
07:31 PM roycroft: and i can say this about it
07:31 PM Tom_L: usually
07:32 PM lcnc-relay: <.le_potato@> controller sends feedback?!
07:32 PM lcnc-relay: <big_kevin420@> kinda
07:32 PM lcnc-relay: <.le_potato@> i mean step controller?
07:32 PM roycroft: i used it in the early 2000s - over 20 years ago - to label fiber optic cables in underground utility vaults
07:32 PM lcnc-relay: <big_kevin420@> not step driver
07:32 PM roycroft: vaults that fill up with mud and water
07:32 PM lcnc-relay: <big_kevin420@> what controller yuo usin
07:32 PM Tom_L: 7i95t
07:32 PM lcnc-relay: <.le_potato@> 7i95t with china step driver
07:32 PM lcnc-relay: <big_kevin420@> then the mesa does it
07:32 PM roycroft: and after all the years, the labels are still legible if you wipe the mud off
07:32 PM lcnc-relay: <.le_potato@> how
07:32 PM Tom_L: ask the fpga wizzard pcw
07:33 PM lcnc-relay: <big_kevin420@> send one step, step was sent
07:33 PM lcnc-relay: <big_kevin420@> theres a feedback diagram in the docs
07:33 PM lcnc-relay: <big_kevin420@> it sends one step and the controller confirms it steppeed
07:33 PM lcnc-relay: <big_kevin420@> or at least
07:33 PM lcnc-relay: <.le_potato@> i get fault for all joint
07:33 PM roycroft: but you can get wrap-around labels for the epson, so i would not spend $650 on a panduit today
07:34 PM Tom_L: stepgen_maxaccel should e 1.5 - 2x max_accel
07:34 PM * roycroft goes out to make his spindle go round and round
07:34 PM lcnc-relay: <.le_potato@> i cant reset, have to restart the linuxcnc
07:34 PM lcnc-relay: <big_kevin420@> the controller confirmed it sent that step to the driver
07:34 PM lcnc-relay: <big_kevin420@> so if you send 50 steps and the controller says it only sent 25 to the driver
07:34 PM lcnc-relay: <big_kevin420@> the thign tom said
07:34 PM lcnc-relay: <big_kevin420@> tom, we talked about this before , but i actually aquired a dual spindle machine last week
07:34 PM lcnc-relay: <big_kevin420@> with 2 z axis
07:35 PM Tom_L: read that forum link
07:35 PM lcnc-relay: <.le_potato@> ah, basicly if i spamming button faster than signal
07:35 PM Tom_L: also, you are better off getting linuxcnc up and running with axis before you jump into another gui
07:35 PM Tom_L: just putting that out there
07:35 PM lcnc-relay: <.le_potato@> axis bugging
07:36 PM lcnc-relay: <big_kevin420@> https://linuxcnc.org/docs/devel/html/hal/rtcomps.html
07:36 PM Tom_L: it's the most stable of all the gui
07:36 PM lcnc-relay: <big_kevin420@> the rock
07:36 PM lcnc-relay: <.le_potato@> missing my Y axis, lol
07:36 PM lcnc-relay: <big_kevin420@> https://media.discordapp.net/attachments/970073761770512384/1393387599623753848/motion.png?ex=687842d3&is=6876f153&hm=0c56f7ef5a0ef8dc2250363d38139df43caf491f1b0e3966553e63a5e5e3a5bb&=&format=webp&quality=lossless
07:36 PM lcnc-relay: <big_kevin420@> that will do iot
07:37 PM lcnc-relay: <big_kevin420@> so i am prepared on how to setup the machine in Lcnc with 2 z axis spindles
07:37 PM lcnc-relay: <big_kevin420@> but the same.... not sure how i can do it
07:38 PM lcnc-relay: <big_kevin420@> the CAM i mean
07:38 PM lcnc-relay: <.le_potato@> ty all, i try it tomorrow
07:38 PM lcnc-relay: <big_kevin420@> if you didnt actually setup a y axis and you try stepping y, it will follow error
07:38 PM lcnc-relay: <.le_potato@> i did it
07:38 PM lcnc-relay: <.le_potato@> works in another gui
07:39 PM roycroft: and the spindle goes round and round
07:39 PM roycroft: yay
07:39 PM roycroft: that's also the first time the new controller has made anything on the machine move
07:39 PM Tom_L: randomly or under full roy control?
07:39 PM xxcoder: spinny
07:39 PM roycroft: manual control
07:39 PM lcnc-relay: <big_kevin420@> you guys know how to reverse enginner a PC104 driver?>
07:39 PM roycroft: now it's time for me to figure out how to control it with the mesa card and linuxcnc
07:40 PM Tom_L: no but i have some PC104 pcs you can have
07:40 PM lcnc-relay: <big_kevin420@> is there like....an adapter for pc104
07:40 PM lcnc-relay: <big_kevin420@> to something else?
07:40 PM * roycroft likes taking small victories and building on them
07:41 PM roycroft: and i looked at my panduit printer when i was out there
07:41 PM roycroft: i don't have the older model - i have the ls8e, as in the link
07:41 PM roycroft: i guess panduit have just made the same model for literally decades
07:41 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/SBC/inside_control.jpg
07:41 PM roycroft: probably because it works and does what it is supposed to do
07:42 PM lcnc-relay: <.le_potato@> u guys doing mess in boxes, lol
07:42 PM Tom_L: that's not my mess
07:42 PM roycroft: that's a very space-efficient setup
07:42 PM lcnc-relay: <skunkworks8841@> well - it didn't go boom...
07:42 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/ECUYihNaXX9Xx9DU7
07:43 PM roycroft: accentuate the positive
07:43 PM lcnc-relay: <.le_potato@> https://prnt.sc/3r4l1AArZUTv
07:43 PM lcnc-relay: <.le_potato@> tfk 😄
07:46 PM lcnc-relay: <skunkworks8841@> .le_potato@ - my stuff is working... 😉
07:46 PM Tom_L: that was a gps monitoring system for a fleet vehicle
07:47 PM Tom_L: i have/had maybe 6 of em
07:47 PM lcnc-relay: <.le_potato@> skunkworks8841@ i know but... just sometimes you could fix it
07:50 PM lcnc-relay: <skunkworks8841@> .le_potato@ maybe you should point out the problems here...
07:50 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/cgbgX4co46n6X6yw6
07:50 PM lcnc-relay: <skunkworks8841@> I am sure there are some
07:50 PM roycroft: so i just read the mesa manual, and the analog spindle interface has spindle+ spindle out (wiper) and spindle -
07:50 PM Tom_L: skunkworks, wtf is wrong with that????
07:50 PM roycroft: i think i can just attach the pins on the jst connector to the mesa board instead of to a physical potentiometer
07:50 PM Tom_L: mad scientist wiring
07:51 PM lcnc-relay: <skunkworks8841@> lol - arm chair quarterbacks...
07:51 PM lcnc-relay: <.le_potato@> https://prnt.sc/sYlyJK9y2q7b
07:51 PM lcnc-relay: <.le_potato@> ahahaha
07:51 PM roycroft: what i really think is that i should get a hall sensor set up so i can monitor spindle rpm at full speed with the potentiometer, and then monitor it again when the mesa board is the potentiometer
07:51 PM xxcoder: man thats massive terminals for that wire
07:51 PM lcnc-relay: <skunkworks8841@> yep. what we had.
07:52 PM lcnc-relay: <skunkworks8841@> and it still works. really quite well. amazingly well.
07:52 PM roycroft: nothing wrong with a little ground bus overkill
07:52 PM lcnc-relay: <.le_potato@> JUST DONT MOVEEE JUST DONT
07:52 PM Tom_L: i don't bother making mine tidy because i figure i'll just be testing something else in it eventually
07:52 PM xxcoder: teal sensor should be plenty
07:52 PM lcnc-relay: <.le_potato@> whats that arduino for?
07:52 PM xxcoder: not that I could find it for sale anywhere now.
07:53 PM lcnc-relay: <skunkworks8841@> .le_potato@ spindle temp for growth
07:54 PM lcnc-relay: <skunkworks8841@> .le_potato@ the first electrical box did thsi
07:54 PM lcnc-relay: <skunkworks8841@> this
07:54 PM lcnc-relay: <skunkworks8841@> https://www.youtube.com/watch?v=mOg5C_TusdM
07:54 PM xxcoder: roycroft: any branding on that hall sensor? the teal one
07:54 PM lcnc-relay: <.le_potato@> looks good tho
07:55 PM lcnc-relay: <.le_potato@> moves like jelly
07:55 PM lcnc-relay: <.le_potato@> jelly? i mean so smooth
07:56 PM Tom_L: skunkworks, did you use those curly whirlies for christmas ornaments?
07:56 PM lcnc-relay: <skunkworks8841@> and the second electrical box.... https://www.youtube.com/watch?v=39q6kvrSBSk&t=53s
07:56 PM roycroft: i don't have it handy - it's in one of the boxes
07:56 PM roycroft: i'm printing out some pinouts and the like for the mesa board analog connection right now
07:56 PM xxcoder: ok
07:56 PM roycroft: i'll head out in a minute to fine a hall sensor
07:56 PM roycroft: i have some others
07:57 PM roycroft: and i have a readout, so i can do it completely outwith the controller/linuxcnc for now
07:57 PM xxcoder: sure just curious on what brand it was etc, because I cant find it anywhere on my buy history on all sites I went to
07:57 PM roycroft: if i can find that stuff
07:57 PM xxcoder: all I know is that it definitely is well above thee max rpm * 2 hz
07:57 PM xxcoder: -e
07:58 PM roycroft: but honestly, it really doesn't matter much right now if the mesa board can work with the jst pins
07:58 PM roycroft: and i see no reason it can't
07:58 PM roycroft: that's what i need to know most immediately
07:59 PM roycroft: and if it works, then i can work on calibrating the exact spindle speed
07:59 PM roycroft: i'll look for that hall sensor, but i suspect that i'll end up just making a jst cable to connect to the mesa board first
07:59 PM Tom_L: you may want a PID loop in lcnc for that
07:59 PM roycroft: yes, i probably do
07:59 PM Tom_L: it helped the bottom end torque on mine
08:00 PM roycroft: both so it doesn't overshoot when changing speeds, and so it can compensate for load
08:00 PM roycroft: all this is likely moot anyway
08:00 PM xxcoder: thre will be very slight error from magnet positions, its not perfectly 180 degree. error should be irrevelent though
08:00 PM Tom_L: it's not perfectly tuned but does a pretty good job
08:00 PM roycroft: it's such a tiny, wimpy spindle i'll probably be running it at full speed 99% of the time
08:00 PM xxcoder: yeah 400w isnt much lol
08:01 PM roycroft: i have my printouts
08:01 PM Tom_L: my sherline was 600w and i ended up adding that water cooling coil around it
08:01 PM roycroft: i'm going to go confirm the jst pins again, and make the cable
08:01 PM Tom_L: until i upgraded
08:01 PM roycroft: and it will probably be dinner time then
08:01 PM lcnc-relay: <.le_potato@> is it possible to set compensation when changing direction on axis?
08:01 PM roycroft: it's pretty much already dinner time
08:01 PM roycroft: linuxcnc can do backlash compensation
08:01 PM Tom_L: it's a per axis comp
08:02 PM lcnc-relay: <.le_potato@> ah, backlash compesation, ty
08:02 PM roycroft: as it should be
08:02 PM lcnc-relay: <.le_potato@> i didnt know how its called
08:02 PM Tom_L: or you can map the ballscrew
08:02 PM Tom_L: i tried that once with no better results
08:02 PM lcnc-relay: <.le_potato@> i will buy linear scale, so
08:03 PM lcnc-relay: <.le_potato@> thats why i needed encoder board
08:04 PM Tom_L: BACKLASH = 0.0000 - Backlash in machine units. Backlash compensation value can be used to make up for small deficiencies in the hardware used to drive an joint. If backlash is added to an joint and you are using steppers the STEPGEN_MAXACCEL must be increased to 1.5 to 2 times the MAX_ACCELERATION for the joint. Excessive backlash compensation can cause an joint to jerk as it changes direction. If a COMP_FILE is specified for a joint
08:04 PM Tom_L: BACKLASH is not used.
08:04 PM Tom_L: comp file to map the screw
08:04 PM Tom_L: http://linuxcnc.org/docs/stable/html/config/ini-config.html#sub:ini:sec:joint-num
08:05 PM lcnc-relay: <skunkworks8841@> the green machine is 800w iirc
08:05 PM Tom_L: 2 formats for the file
08:05 PM lcnc-relay: <.le_potato@> ty Tom
08:05 PM lcnc-relay: <.le_potato@> i think tomorrow i will mill :3
08:05 PM Tom_L: use backlash sparingly
08:06 PM lcnc-relay: <skunkworks8841@> yah - it works ok - but no backlash is better
08:06 PM Tom_L: it is takein up at the start of a cut in what seems like a rapid move
08:06 PM Tom_L: if you have alot of backlash you will notice it right away
08:06 PM xxcoder: comps should be final stage yeah. trim machine as much as possible, renove backlashes as possible etc
08:06 PM lcnc-relay: <.le_potato@> i have like 0.1mm on Z :/
08:07 PM lcnc-relay: <.le_potato@> others like 0.03mm
08:07 PM Tom_L: z likely isn't as bad as x or y
08:07 PM lcnc-relay: <skunkworks8841@> gravity
08:07 PM xxcoder: id look around and find where looseness is coming from
08:08 PM Tom_L: .03mm isn't much
08:08 PM Tom_L: your steppers may not even be able to compensate for that
08:08 PM lcnc-relay: <.le_potato@> yeah, would need gear ratio for it
08:08 PM xxcoder: 0.03mm seems fine. 0.1mm is eh, though it being on z probably would be gravity "cancelled"
08:09 PM lcnc-relay: <.le_potato@> sadly not gravity
08:09 PM lcnc-relay: <.le_potato@> if i sit on the table, its not even move, lol
08:10 PM Tom_L: no but if you lift it, it likely would
08:10 PM Tom_L: gravity
08:10 PM lcnc-relay: <.le_potato@> i did try, nope
08:10 PM lcnc-relay: <.le_potato@> or i cant lift enough, lol
08:11 PM Tom_L: from what i recall, it looked pretty heavy
08:11 PM lcnc-relay: <.le_potato@> the table is about 400kg
08:28 PM roycroft: these old eyes cannot ready the silk screening on the mesa board, nor the printout of the connector diagram
08:29 PM roycroft: time to blow up the pdf to old person size
08:29 PM xxcoder: lol yeah. im old enough to need len sometimes to read small print. that or use phone camera zoom'
08:30 PM roycroft: i have it sorted now
08:30 PM roycroft: and the nice thing is that the jst connector on the controller board has male pins, and the female pins fit over them nicely without having to install in a shell
08:30 PM roycroft: so i can test without actually building the cable
08:30 PM * roycroft goes back to do some more wiring
09:09 PM roycroft: ok, i have the spindle controller wired up to the mesa card
09:10 PM roycroft: i believe i need to configure the analog port in my mesa config next
09:10 PM roycroft: but after that, is there a utility i can use to control the spindle without having to do it in linuxcnc?
09:11 PM roycroft: and iirc tom_l gave me some hal config lines for the pwm stuff
09:11 PM * roycroft is going to make dinner, and then get back to that
09:44 PM Tom_L: i'm not sure what that would have been
09:46 PM Tom_L: unless it was from my config files
09:47 PM Tom_L: mine has encoder feedback though
09:48 PM roycroft: i need to look, but i think you gave me part of your config file
09:48 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/configs/NEW_MILL/new_mill.hal
09:48 PM roycroft: but if not, no worries
09:48 PM Tom_L: maybe something in that
09:48 PM roycroft: i'll get it sorted
09:48 PM Tom_L: search 'spindle' and you'll find most of it
09:49 PM Tom_L: mine will be a bit different
09:50 PM Tom_L: my analog spindle circuit is on a daughter board, not integrated on the main mesa board
09:53 PM * Tom_L calls it a night
10:01 PM roycroft: thanks
10:01 PM roycroft: i'll get it sorted
10:01 PM roycroft: maybe tonight or maybe not
10:01 PM roycroft: i made a lot of progress today, and i'm starting to feel fatigued, so i may call it a day as well soon
10:06 PM roycroft: that was my first soldering at the new house, and the electronics bench has been piled up with random stuff ever since i moved here, so getting that tidied up alone was a big accomplishment
10:20 PM xxcoder: roy you ready for the fire tomorrow?
10:23 PM roycroft: what fire?
10:23 PM roycroft: is there a fire in the forecast?
10:27 PM xxcoder: lol well not literal fire, but 92f here tomorrow. ouch
10:27 PM xxcoder: it gets cooler after but yeah
10:40 PM -!- #linuxcnc mode set to +v by ChanServ
10:42 PM roycroft: oh, it's not going to get too hot here
10:43 PM xxcoder: bah lucky you lol
10:43 PM roycroft: well, kind of, i guess
10:43 PM roycroft: 34 tomorrow
10:43 PM roycroft: but it was 37 on sunday at the fair
10:44 PM roycroft: it was a lot cooler today, and will be again starting thursday
10:44 PM xxcoder: 34c is 93f. hotter than here at 92f
10:44 PM roycroft: i'm getting a new windshield in my car tomorrow, so i'll be hanging out at the glass shop
10:44 PM roycroft: hopefully it has ac
10:47 PM roycroft: i thought it was going to be more like 30 tomorrow
10:47 PM roycroft: i've been busy and not paying attention to the forecast
10:48 PM * roycroft should irrigate in the morning before heading to town
