12:00 AM roycroft: i go to the liquor store for liquor
12:19 AM roycroft: i go to my brita in the fridge for water
12:19 AM roycroft: bottled water is pretty wasteful
12:19 AM xxcoder: I go to nowhere for liquor
12:19 AM roycroft: i have various size water bottles to fill for when i'm away from home, depending on how long i'll be gone
12:19 AM xxcoder: I use high qualiy tap water for water
12:19 AM fluffywolf: I also go nowhere for liquor.
12:19 AM fluffywolf: you think bottled water is wasteful, but bottled idiocy is ok? heh
12:19 AM * roycroft does not recall discussing bottled idiocy at all
12:28 AM * roycroft does not drink to get drunk, an does not drink enough to get drunk
12:29 AM roycroft: i'm too old for that
12:41 AM lcnc-relay: <meisterdippel@> moin
01:45 AM Deejay: moin
04:29 AM Tom_L: morning
08:29 AM lcnc-relay: <lucid.nonsense@> G'day
09:10 AM lcnc-relay: <lesliet@> good timezone
09:12 AM rdtsc-w: well-wishes from GMT-5
09:25 AM lcnc-relay: <lucid.nonsense@> The same from GMT 😊
09:28 AM lcnc-relay: <lucid.nonsense@> Nvidia is so going to pop
09:29 AM lcnc-relay: <lucid.nonsense@> Night be worse than 2006
09:29 AM lcnc-relay: <lucid.nonsense@> might
09:32 AM lcnc-relay: <lucid.nonsense@> What pisses me off with these tech bubbles is that when they crash they take the whole economy down with them
11:35 AM rdtsc-w: PC performance has waned: huge changes in the 90s, big in the 2000s, mediocre in the 2010's, and not much to talk about in the 2020's
11:37 AM lcnc-relay: <skunkworks8841@> well - I figured out what the main jet is.. boy - they must have made about 20 versions of this carb.. the main jet is in about 3 different locations depending..
11:37 AM lcnc-relay: <skunkworks8841@> almost evey orifice on this thing was plugged
11:37 AM lcnc-relay: <skunkworks8841@> I have to make sure there is a filter somewhere on this thing
11:38 AM lcnc-relay: <skunkworks8841@> still waiting on parts though
11:38 AM lcnc-relay: <skunkworks8841@> float is in and adjusted.. most of the metering stuff is in.
11:39 AM roycroft: we've definitely pushd up against speed of light issues
11:40 AM roycroft: skunkworks8841: drop some ex-lax tablets in your cleaning solution
11:44 AM xxcoder: its more and more about how many transitors on cpu than hz
11:46 AM Rab: I'm not sure about this touch plate posted earlier...it's got their stupid logo all over the surface, and something like a bead blasted finish? How flat and repeatable can that be? https://us.openbuilds.com/xyz-touch-probe-plus/
11:52 AM xxcoder: ugh yeah dunno
11:52 AM xxcoder: shot blasting may average it well, but engraving?
11:53 AM xxcoder: seems youre supposed to touch down in middle of logo based on pictures
11:55 AM Rab: Their example photo shows touch-off in the center of the logo. But it also shows a tapered micro-endmill, which is probably small enough that it's not repeatable on the finish texture!
11:55 AM xxcoder: yeah pointy tools is going to be a problem, depending on how large varance is
11:55 AM Rab: I mean, by a tiny amount that's totally irrelevant to the wooden workpiece in the photo, but still.
11:55 AM xxcoder: for some uses certain range of error dont matter
11:56 AM xxcoder: indeed
11:57 AM Rab: Maybe if that matters, OpenBuilds isn't the right platform for me.
11:57 AM roycroft: with a tapered cutter you should try to be spot on
11:57 AM roycroft: since any change in z is also a change in x and y
11:58 AM xxcoder: thats the fun with tapered tools
11:59 AM Rab: Yeah...fine-pitch PCB engraving with conical cutters was a death-affirming experience, that's when I decided to get boards commercially made.
12:00 PM xxcoder: pcbs I would probe entire surface
12:00 PM xxcoder: I remember that project where someone probes mouse surface and engraves hacker skull logo on it.
12:01 PM xxcoder: computer mouse looked cool lol
12:01 PM xxcoder: I bet it'd be cooler if engrave was filled with black epoxy
12:01 PM roycroft: affinity just announced that they're finally combining all their apps into one
12:02 PM roycroft: designer, photo, and publisher are all part of the new "affinity studio"
12:02 PM xxcoder: sounds like its going to suck

12:18 PM xxcoder: banned. spammer
12:18 PM lcnc-relay: <skunkworks8841@> I had simple green in the shop.. that is what I used. Worked good
12:18 PM roycroft: i think it will be great, xxcoder
12:23 PM xxcoder: bridge down for few min
12:25 PM xxcoder: back up
12:37 PM roycroft: i've been using adobe products since they came on 5-1/4" floppies that installed on windows 3.11
12:37 PM roycroft: but i mostly stopped a few years ago when they moved to the rentalware model
12:42 PM rdtsc-w: i've acclimated to gimp... it has its quirks for sure
12:42 PM Tom_L: i'd purchased a cd from them to avoid rental. right afterward they rendered it useless and forced the rentals on me
12:43 PM * rdtsc-w doesn't do rental-ware
12:43 PM Tom_L: rdtsc-w, can you link (in flex) those 180deg adapters for the touch monitor?
12:43 PM Tom_L: over there so it doesn't get lost
12:43 PM Tom_L: i'm a day closer to getting one
12:44 PM Tom_L: i may have the hdmi one located but not usb
01:27 PM lcnc-relay: <lucid.nonsense@> Krita is orders of magnitude better than gimp, tried darkrable for raw photo, seemed OK, but strange interface
01:28 PM roycroft: the affinty suite works well for me
01:28 PM roycroft: and it's pretty inexpensive - i think i paid $100 for it
01:28 PM roycroft: but as i said earlier, it appears that the new integrated version will be free, with the ai stuff a paid add-on
01:29 PM roycroft: i personally would rather avoid the ai stuff, so i'm fine with it not being bundled with the main product
01:32 PM lcnc-relay: <lucid.nonsense@> Yeah I prefer affinity too
02:13 PM lcnc-relay: <xxcoder@> bridge annoyance with images might be finally fixed
02:13 PM lcnc-relay: <xxcoder@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/KBqdMGGYKJQjygvbfJXtjoxX/Jw9cNcNyanQ/ratjam.gif
02:14 PM lcnc-relay: <xxcoder@> ok seems fine. awesome. I will be making server announcement for discord side lol
02:37 PM lcnc-relay: <oddname_skane@> oh cool
03:27 PM lcnc-relay: <redboro_@> Anyone running 7i96s + 7i85s willing to answer a couple of questions?
03:34 PM Tom_L: ask
03:42 PM lcnc-relay: <xxcoder@> redboro_@: yeah its always better to ask question than ask to ask a question 🙂
03:57 PM JT-Shop: sounds like some double talk there
04:09 PM pcw: so I can't ask to ask to ask a question?
04:10 PM roycroft: yes, you can, but you can't ask to ask to ask to ask a question
04:10 PM roycroft: you must make an odd number of asks, not an even one
04:17 PM lcnc-relay: <finboyslick@> See, this is why I missed you guys.
04:17 PM xxcoder: lol
04:25 PM rdtsc-w is now known as rdtsc-odd
04:27 PM rdtsc-odd is now known as rdtsc-w
04:29 PM lcnc-relay: <lesliet@> roycroft: I mean, they can... it's their askstorisk.
05:16 PM lcnc-relay: <redboro_@> xxcoder@: Point taken!
05:16 PM lcnc-relay: <redboro_@> Will 7i85s show up on readhmid?
05:18 PM lcnc-relay: <redboro_@> Can I use the encoder channels on 7i85s for linear encoders to track position of steppers driven off 7i96s or would I need to wire the steppers to 7i85s instead?
05:18 PM JT-Shop: with everything connected and powered up you can get a list of all the hal pins
05:19 PM JT-Shop: steppers with encoders is very challenging but a few have done that
05:19 PM lcnc-relay: <redboro_@> What’s strange is I’m only getting encoder channels 0-3 instead of 0-4, I’m not sure if it’s enc 3 on 7i85s that’s dropping off or the sole enc on 7i96s
05:19 PM JT-Shop: the issue is you can't tell a stepper to apply more power to catch up
05:20 PM lcnc-relay: <redboro_@> Oh so you’ll just eventually get a following error instead of rectifying mismatch?
05:20 PM JT-Shop: yup
05:20 PM lcnc-relay: <redboro_@> Well shit
05:20 PM JT-Shop: sorry but that's how steppers work
05:21 PM * JT-Shop wonders if pcw is around
05:21 PM lcnc-relay: <redboro_@> I have linear encoders on my lathe from the DRO, was hoping to use those to keep everything tight but it sounds like I should just use the built in encoders on the stepper to track lost steps instead?
05:22 PM lcnc-relay: <redboro_@> Forgive me, I’m uninitiated, PCW?
05:22 PM JT-Shop: for steppers it's best to not drive them hard enough to loose steps
05:22 PM JT-Shop: he is the chief bottle washer at Mesa
05:23 PM lcnc-relay: <redboro_@> It’s honest work
05:23 PM JT-Shop: and he's the chief sheep tender I 'think'
05:24 PM lcnc-relay: <redboro_@> Alright, so closed loop feedback basically pointless, even if only using the built in encoders of the stepper?
05:24 PM pcw: I think a 7I96S/7I85 maps the encoders: 7I85 0..3 7I96S 4
05:24 PM JT-Shop: Hi Peter
05:25 PM pcw: Close loop win linear encoders can improve accuracy even with step/dir drives
05:25 PM lcnc-relay: <redboro_@> I’m not in front of my build right now, but assuming I can just change encoders = 4 to 5 and enc 4 (7i96s) will populate?
05:25 PM pcw: but it's best to get open loop working well first
05:26 PM pcw: Yes, set num_encoders to 5
05:26 PM lcnc-relay: <redboro_@> Good to know, and is there issue with driving steppers from TBx on 7i96s but bringing encoders from say enc0 & enc1 from 7i95s?
05:27 PM lcnc-relay: <redboro_@> * 7i85s
05:27 PM pcw: no
05:27 PM lcnc-relay: <redboro_@> 😮💨
05:28 PM lcnc-relay: <redboro_@> Great, that will keep me busy for awhile, but while I’ve got y’all here…any issue using enc2 & enc 3 from 7i85s to drive jogging with MPG wheels? Can I jog simultaneously?
05:31 PM Tom_L: different axis i assume
05:31 PM Tom_L: if the mpg is tied to the axis i would think so
05:34 PM JT-Shop: you can do that in HAL
05:34 PM Tom_L: i chose to use an axis switch and one MPG
05:36 PM Tom_L: axis.x.jog-enable, axis.x.jog-counts, axis.x.jog-scale
05:36 PM Tom_L: are the basic signals
05:36 PM JT-Shop: that's what I do I have two selector switches one for increment and one for axis
05:36 PM Tom_L: same
05:37 PM Tom_L: i think andy has 2 MPG on his lathe but not sure how he's wired them
05:37 PM Tom_L: i can see that more for a lathe
05:46 PM lcnc-relay: <fluffyalpaca@> I submitted a correction to politico and they actually fixed the article
05:46 PM lcnc-relay: <fluffyalpaca@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/jsINmMDfklDDwlmiBTpatVSK/LGwitFtail8/Screenshot_20251030-184016.png
05:46 PM lcnc-relay: <fluffyalpaca@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/MyORaTJfWSszdFfdNiJqiNRq/18ib6cOuWok/Screenshot_20251030-184040.png
05:47 PM lcnc-relay: <redboro_@> If I had my druthers, I’ll have push buttons to drive each axis +&- continuously (like the keyboard arrow keys) and MPG hand wheels jogging at set increments. I’d like to avoid an axis selector switch for ergonomics, going for a user experience similar to Prototrak manual operation
05:48 PM JT-Shop: you can do that easy with Flex GUI
05:49 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/rpi5/Rpi5_touch_jog.png
05:49 PM Tom_L: proof
05:50 PM roycroft: the term "mil" should be banned (as well as "thou", just because it's stupid)
05:50 PM Tom_L: what about tenths?
05:51 PM roycroft: i begrudgingly accept that, because "ten thousandths" is rather wordy
05:51 PM roycroft: and i don't complain about the use of "thou"
05:51 PM roycroft: i just grimace a bit
05:51 PM JT-Shop: it's just a few stone
05:51 PM Tom_L: mil is a bit irritating, i'll give you that
05:51 PM lcnc-relay: <xxcoder@> redboro btw emoji reacts dont work across bridge 😄
05:52 PM roycroft: but "mil" can mean "thousandth of an inch", "millimeter", or, in this case which i've never encountered before "millionth of an inch"
05:52 PM JT-Shop: yup
05:52 PM lcnc-relay: <redboro_@> Tom_L: Very good to know, thank you
05:52 PM * JT-Shop calls it a day
05:52 PM roycroft: but "bit" is the tooling term that irritates me the most
05:53 PM Tom_L: bit belongs on a horse
05:53 PM lcnc-relay: <redboro_@> Now this might catch some eye rolls, but supposing I get my linear encoders online, I’ve currently got my original manual hand wheels in tact and the steppers mounted at the opposite end of the lead screws. I would like to be able to disable the steppers and wheel the lathe around manually. Would a simple on/off switch to the enable pin be a fine way to accomplish this, or is there an equally simple (maybe more robust?) software...
05:53 PM roycroft: exactly
05:53 PM lcnc-relay: ... option?
05:53 PM lcnc-relay: You might be asking, ‘why would you want manual hand wheels if you set up your MPGs for jogging?’
05:53 PM lcnc-relay: Because I’m scared, that’s why!
05:53 PM roycroft: and i'll concede that there is a defined meaning of "bit" regarding tooling
05:53 PM roycroft: but a "bit" is a drilling tool
05:53 PM roycroft: period
05:53 PM lcnc-relay: <redboro_@> But if you get rid of bits, what does that mean for bobs?
05:53 PM roycroft: it's not an end mill or any other kind of side cutting or forming tool
05:53 PM roycroft: i don't want to get rid of bits
05:54 PM roycroft: i just want the term to be used in the proper context
05:54 PM Tom_L: redboro, you could but i move mine around manually with the MPG
05:54 PM lcnc-relay: <fluffyalpaca@> JT-Shop: How many sun and shaku is the length of your lathe bed? Babylonian cubits are also acceptable
05:54 PM Tom_L: you had to look that one up
05:54 PM roycroft: no they are not
05:55 PM roycroft: cubits contains 'bits'
05:55 PM roycroft: so unless you're talking about horses, they are not acceptable
05:55 PM lcnc-relay: <redboro_@> I might as well be using cubits, I’ve got an inch spindle nose thread and a metric lead screw
05:55 PM Tom_L: so?
05:55 PM Tom_L: my ballscrews are metric
05:56 PM lcnc-relay: <redboro_@> Tom_L: You’re happy enough with the MPGs?
05:56 PM roycroft: it doesn't matter
05:56 PM Tom_L: absolutely
05:56 PM roycroft: they all measure in 'mils'
05:56 PM roycroft: and mils can be us customary or metric, as we just established
05:56 PM Tom_L: i have 3 'coarse to fine' settings
05:56 PM lcnc-relay: <fluffyalpaca@> I only measure things in wadokei time
05:57 PM Tom_L: redboro, not store bought either: http://tom-itx.no-ip.biz:443/~webpage/cnc/pendant/pendant2.jpg
05:57 PM roycroft: you don't use scaramuccis or lettuces any more?
05:57 PM lcnc-relay: <redboro_@> Oh that’s slick tom
05:58 PM Tom_L: i redid the face so the letters were more uniform
05:58 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/pendant/new/Pendant2.jpg
05:58 PM lcnc-relay: <redboro_@> I’ll eventually make a housing but I’m working with 2 of these right now
05:58 PM lcnc-relay: <redboro_@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/sblHdrkHzytxMOMdhJIQOWFJ/Dto2BCaoyYI/IMG_2023.png
05:59 PM lcnc-relay: <redboro_@> Would y’all recommend going straight to flex gui or getting things 99% set up in something like axis?
05:59 PM Tom_L: https://www.ebay.com/itm/126408434704
06:00 PM Tom_L: i help test it so of couse flexgui
06:00 PM Tom_L: actually setting up the first time i'd use axis
06:00 PM lcnc-relay: <redboro_@> For reference I’m finally comfortable in mesact and pncconf but I’m still reading at a 3rd grade level in hal & ini
06:00 PM roycroft: my mcmaster order should be arriving presently - i can finally get my table saw fence mounted properly
06:00 PM Tom_L: use mesact over pncconf
06:00 PM Tom_L: bet that was a secret
06:01 PM Tom_L: https://www.gnipsel.com/linuxcnc/mesact/index.html
06:01 PM Tom_L: same guy that did flex
06:01 PM lcnc-relay: <redboro_@> Okay question on the MPGs, in the Mesa manual it says you don’t need to wire the a- and b- terminals, is that a rule or a recommendation? Which did you do?
06:01 PM * roycroft sings the song "oh oh the big brown ups truck is a'coming down the street, oh please let it be for me. oh oh the big brown ups truck is a'coming down the street, i wish i wish i knew what it could be"
06:01 PM Tom_L: not unless you want full duplex
06:01 PM Tom_L: i think that's the right term
06:02 PM Tom_L: i used just the single wires
06:02 PM lcnc-relay: <redboro_@> Mesact was what got me to finally get my firmware flashed correctly but pncconf my push buttons worked right away 😂
06:02 PM Tom_L: they both have their place i suppose
06:04 PM lcnc-relay: <redboro_@> Do you use 7i96s_7i85s or one or the other when naming your encoders in hal?
06:04 PM Tom_L: my setup is older so my cards are also older ones
06:04 PM Tom_L: as far as pin connections?
06:05 PM Tom_L: hal show should get you that
06:05 PM Tom_L: or mesaflash -readhmid
06:05 PM Tom_L: + a couple more cmd line switches...
06:07 PM Tom_L: for the pin name it would likely be something like 7i96s.0.7i85s.something something
06:07 PM Tom_L: or some such format
06:07 PM lcnc-relay: <redboro_@> Noted, I’m going to wait to bother y’all again until I’m in front of my computer. Really appreciate the advice & banter
06:08 PM lcnc-relay: <skunkworks8841@> differential connection...
06:08 PM Tom_L: thanks
06:08 PM lcnc-relay: <skunkworks8841@> or single ended..
06:08 PM Tom_L: brain is starting to forget
06:09 PM lcnc-relay: <skunkworks8841@> I had to think about it
06:09 PM Tom_L: you get the carb working?
06:13 PM lcnc-relay: <skunkworks8841@> it is coming together. still waiting on one part.
06:15 PM lcnc-relay: <skunkworks8841@> says it won't be here until monday
06:20 PM lcnc-relay: <lesliet@> Drill motor: the part that drives the drill
06:20 PM lcnc-relay: Drill: the tool that goes in a drill motor, spins and makes holes in things
06:20 PM lcnc-relay: Drill bits: what you have left after a drill breaks
06:21 PM lcnc-relay: <skunkworks8841@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/yJlGoKLwHHorEKDjrcwAqbfD/2JlgIZKkCDM/PXL_20251030_231726295.jpg
06:33 PM lcnc-relay: <ccatlett1984@> fluffyalpaca@: fluffyalpaca@ I have a friend, that holds tolerances of 50 millionths on machined parts, it can be done, just not usually required.
06:33 PM lcnc-relay: <fluffyalpaca@> ccatlett1984@: Swiss lathe?
06:34 PM lcnc-relay: <ccatlett1984@> not a swiss, can't remember the manufacturer
06:34 PM lcnc-relay: <ccatlett1984@> last step for tolerances like that, is usually diamond lapping
06:36 PM lcnc-relay: <fluffyalpaca@> Diamond won't work with anything ferritic, though, yes?
06:36 PM lcnc-relay: <fluffyalpaca@> The carbon binds to the steel
06:36 PM lcnc-relay: <fluffyalpaca@> So it would have to be done on other metals
06:50 PM Tom_L: skunkworks, you can tell it's old by the float
06:59 PM lcnc-relay: <john.obrien@> ccatlett1984@: For that kind of tolerances I think you need a machine that compensates for thermal expansion like an Okuma. Was it an Okuma?
07:01 PM lcnc-relay: <ccatlett1984@> might be, I'll have to ask. I know it's a heck of a process, machine, heat treat, Grind, diamond lap
07:01 PM lcnc-relay: <ccatlett1984@> one part are the calibration discs for air gauges
07:01 PM lcnc-relay: <skunkworks8841@> Tom_L: yes.. and it still floats
07:01 PM lcnc-relay: <ccatlett1984@> it's a hole in the middle of a disc, looks sooo simple, it's not 😉
07:04 PM Tom_L: my bud used air gages for some holes. they're about as accurate as you can get
07:05 PM xxcoder: I am kinda sad I ended up never using one
07:09 PM Tom_L: you could use bottled nitrogen for a little better result
07:10 PM xxcoder: I remember trying to push company into buying another air gage for a61 area
07:10 PM lcnc-relay: <greg_cnc@> Grinding, lapping, honing, might be inspected with air gage. You'd really have to have the process down to use it with turning. Turning to a few tenths is rather common, even with clapped out machines as long as they are repeatable, but it's not fun.
07:10 PM xxcoder: we measure so many holes
07:10 PM Tom_L: greg_cnc, they change throughout the day
07:10 PM xxcoder: we often run one or 2 parts in 2 horzional mill
07:11 PM lcnc-relay: <greg_cnc@> what changes?
07:12 PM Tom_L: the diameter
07:12 PM Tom_L: slightly
07:12 PM Tom_L: i suppose some have comp for that but the cadet didn't
07:13 PM lcnc-relay: <greg_cnc@> chasing machines is a pain, but some shops take the kind of work that requires it
07:13 PM Tom_L: his was mostly mill but did have one cnc lathe
07:13 PM lcnc-relay: <greg_cnc@> thermal comp works if it actually works.
07:14 PM xxcoder: its always smart to have in least one lathe
07:14 PM Tom_L: i've never messed with it
07:14 PM xxcoder: easier to make some parts round first
07:14 PM xxcoder: shop I used to work at had hmm 20? lathes
07:14 PM Tom_L: xxcoder, or have a mill turn
07:15 PM xxcoder: they was planning to add another 2 swiss lathes before ecomony crashed by covid
07:15 PM xxcoder: those fancy ons
07:15 PM Tom_L: my kid's work had one...9 axis i think
07:15 PM Tom_L: has
07:16 PM Tom_L: nobody really knows how to program it right though
07:16 PM lcnc-relay: <greg_cnc@> I'm trying oil in the lathe. It turns out that it will get hotter with oil, where as with soluble the evaporation stabillized fairly quickly. so I have to relearn it.
07:16 PM xxcoder: always nice. those swiss lathes is riciously complex

07:17 PM lcnc-relay: <greg_cnc@> doesn't need to be swiss to have two spindles and three turrets with some Y thrown in.
07:18 PM xxcoder: agreed, but it was at shop I worked at lol
07:19 PM xxcoder: skunk probably want to add few words for that video link lol now that we fixed briging for images, but embedded for some stuff will not work anymore, to stop link echoes
07:24 PM lcnc-relay: <greg_cnc@> I haven't done anything linuxcnc in a while. My little frankenmill get fired up occasionally.The little lathe retrofit has been untouched for an embarrassingly long time. Every once in a while I think about retrofittting my mill to single phase 250V (spindle), servos, and Linuxcnc. it would really improve the machine, but seems like more effort than it's worth, until I can get something else.

08:17 PM lcnc-relay: <skunkworks8841@> Xxcoder?
08:17 PM xxcoder: yeah?
08:18 PM lcnc-relay: <skunkworks8841@> I didn't understand your comment.. lol
08:18 PM lcnc-relay: <skunkworks8841@> It has been a long day
08:18 PM xxcoder: ahh if its just video url its bit hard to tell what it is about :)
08:19 PM lcnc-relay: <skunkworks8841@> Ah. Sorry. I posted the link in regards to the temp comp conversation. I could have added a few words
08:19 PM xxcoder: no problem at all :D
08:50 PM lcnc-relay: <greg_cnc@> skunkworks8841@: I remember watching that some time ago. I haven't been around here since 2020 or so.
08:51 PM lcnc-relay: <skunkworks8841@> I am old... 😉
08:54 PM lcnc-relay: <skunkworks8841@> greg_cnc@ did you see this? https://youtu.be/Q9zhi8Mc1fE?si=_GPF8oa2XvormPQN
08:54 PM lcnc-relay: <skunkworks8841@> Some spindle synced motion...
08:59 PM rdtsc-wtf is now known as rdtsc
09:02 PM lcnc-relay: <greg_cnc@> Yes. I'm a subscriber so i see them all.
09:02 PM lcnc-relay: <skunkworks8841@> Ah.. thank you
09:15 PM lcnc-relay: <greg_cnc@> hard to believe the cutter doesn't give up at the angles it's working at.
09:16 PM lcnc-relay: <skunkworks8841@> The cutter needs relief for it to work
10:05 PM lcnc-relay: <redboro_@> Alright I'm back with MPG questions, as a reminder, I'm working with 7i96s + 7i85s. halshow sees my x axis mpg (enc3) and its double reporting my spindle encoder (4&5). Issue is, I'm not getting anything from enc2, where I've got my z axis mpg. Whats strange too, on the mpg thats showing (enc3), I get .15v between A & gnd, on the mpg that isnt showing (enc2), I get 4.5v.
10:05 PM lcnc-relay: on enc 2 I've got A to 17, gnd to 19, B to 20, 5v to 22.
10:05 PM lcnc-relay: on enc 3 I've got A to 1, gnd to 3, B to 4, 5v to 6.
10:05 PM lcnc-relay: Can someone confirm I'm not having a dyslexic moment somewhere? Anything obvious I'm missing?

10:06 PM lcnc-relay: Can someone confirm I'm not having a dyslexic moment somewhere? Anything obvious I'm missing?
10:06 PM lcnc-relay: At one point I definitely had enc2 wired up wrong, is it possible I damaged it? I tried my backup mpg, got the same results.
10:06 PM lcnc-relay: <xxcoder@> redboro_@: please dont edit large block of text
10:07 PM lcnc-relay: <redboro_@> apologies, the last line was added, only change
10:07 PM lcnc-relay: <xxcoder@> yeah and irc entire thing was shown again 🙂
10:07 PM lcnc-relay: <skunkworks8841@> these are single ended encoders (not using the a- and b-?_
10:08 PM lcnc-relay: <redboro_@> correct skunkworks
10:09 PM lcnc-relay: <skunkworks8841@> you have the jumpers set to single ended?
10:10 PM lcnc-relay: <redboro_@> all jumpers are down
10:10 PM lcnc-relay: <redboro_@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/rOrnRdVeXJwmmJDJfdAYfXIJ/WusqeeOlCtA/image.png
10:10 PM lcnc-relay: <skunkworks8841@> so they should be all up.
10:11 PM lcnc-relay: <skunkworks8841@> you have ttl encoders
10:11 PM lcnc-relay: <redboro_@> another clue, I pulled the block from enc3 and installed it on enc2, I again got .15v between A and GND, and halshow erraticaly showed switching between 0 & -1 when mpg was spun
10:12 PM lcnc-relay: <redboro_@> let me give that a shot, but why would enc 3 show properly if jumpers are set the same?
10:13 PM lcnc-relay: <skunkworks8841@> as you spin the encoder - you will get a toggling between 0 and 1
10:13 PM lcnc-relay: <skunkworks8841@> https://en.wikipedia.org/wiki/Incremental_encoder
10:14 PM lcnc-relay: <skunkworks8841@> you will get a square wave on each pin that is offset by 90 degrees
10:19 PM lcnc-relay: <redboro_@> All jumpers up, enc 3 counting and spindle encoder counting, still nada from enc 2. still getting 5v between A and gnd on enc2, .15 on enc 3 A to gnd
10:19 PM lcnc-relay: <redboro_@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/dVPIVtsjIuTcouCOUJyNdQRn/U1lWx7WnRHM/image.png
10:21 PM lcnc-relay: <redboro_@> but when I switch the block from enc 3 to enc 2, I get .15v between A and gnd. And if I put the block from enc2 onto enc 3 I get 5v between A and gnd. Even when switching MPGs, I wonder if this is a hardware issue?
11:21 PM lcnc-relay: <redboro_@> Changed out my wiring harness and now everything is happy, must have been a nick in one of my wires causing a short
