12:50 AM XXCoder: dude https://youtu.be/2TJEzdqtXlQ
12:56 AM XXCoder: damn dangerous
01:09 AM miss0r: I have a magnetic drill on my workbench. On this one the magnet is *actualy* broken.
01:10 AM miss0r: thats a first
01:10 AM miss0r: XXCoder: That is why you should always buy namebrands from reputable sources
01:11 AM XXCoder: yeah that, thankfully, is not my videp
01:11 AM XXCoder: we recently replaced one breaker by electrician, he had 45 usd or 120 usd options. I picked 120 usd one as that one is proper
01:11 AM miss0r: I know... heh for some reason I would be surprised if you turned out to be bigclive :)
01:12 AM miss0r: wow that is expensive :D
01:12 AM XXCoder: some people try to hide famousness, but yeah im not famous in any kind heh
01:12 AM miss0r: a particular large one? or something special=
01:12 AM XXCoder: it has backup security in case breaker fails
01:13 AM miss0r: i.e. a switch mounted on the side? :)
01:13 AM miss0r: You see, before I became a machine repairman, I was an electrician for 10 years
01:13 AM XXCoder: llol nah it has another wire connecting to ground I think
01:13 AM miss0r: hehe
01:13 AM miss0r: and that sounds realy pricy to me.
01:14 AM XXCoder: one thing that impressed the fuck out of me is how neat his writing is
01:14 AM XXCoder: its like art
01:14 AM miss0r: example, a 3p+n 10a c breaker will only set me back 10$
01:14 AM miss0r: if I choose a proper one like Siemens or Aeg
01:15 AM miss0r: yeah. Have I ever shown you some wire porn I've made?
01:16 AM XXCoder: im not sure think that includes installation
01:16 AM miss0r: makes sense then
01:16 AM miss0r: that what realy costs
01:16 AM XXCoder: basic one with no backup is 45 usd one, that ones probably $10 breaker
01:16 AM miss0r: https://imgur.com/a/iQ0JWn4
01:16 AM XXCoder: fancy!
01:16 AM miss0r: the last project I build before leaving the electrical company
01:17 AM XXCoder: why did you move on im curious
01:17 AM XXCoder: since its one of higher paid jobs
01:17 AM miss0r: LOL
01:17 AM miss0r: I went from doing that to being selfemployed :D
01:18 AM miss0r: I guess I've always wanted to do more of the mechanical work with industrial machinery
01:18 AM miss0r: and being an electrician didn't quite cover that angle
01:18 AM miss0r: so I guess I just took a leap. THAT and my boss was driving me nuts
01:19 AM miss0r: I mean. I spend 3weeks building that shipping container (FROM SCRATCH - inside that is) me and me alone.
01:19 AM miss0r: after 1 week he started asking me why I werent done yet
01:19 AM miss0r: which is basically standard practice there
01:19 AM XXCoder: jeez
01:20 AM XXCoder: company i worked for made bunch of massively complex containers for certain aircraft parts
01:20 AM XXCoder: its large plate thing
01:20 AM XXCoder: it took them couple months to make a pair
01:20 AM miss0r: I feel like 3 weeks is pretty decent for that build. (This includes figuering out what to order and order it, make drawings, getting drawings approved by client, routing mounting ect ect)
01:20 AM miss0r: yeah
01:20 AM XXCoder: literally everything inside is covered by cheap rug
01:21 AM XXCoder: and its 1" slots, 25 for one
01:21 AM miss0r: because of scratch proofing it?
01:21 AM XXCoder: yeah
01:21 AM XXCoder: and very strong hold so bangs dont dent or deform part
01:21 AM miss0r: better not get a chip in there then, ha`? :)
01:21 AM XXCoder: yeah FOD failure
01:21 AM miss0r: FOD ?
01:21 AM XXCoder: forgein object derbis
01:22 AM miss0r: makes sense :)
01:22 AM XXCoder: ie anything that doesnt belong
01:22 AM XXCoder: one screwdriver destroyed jet engine
01:22 AM XXCoder: turns out guy who worked on it forgot to take account of all his tools
01:22 AM miss0r: actual case? or just an example?
01:22 AM miss0r: oh shit
01:22 AM XXCoder: actual. not company i worked for
01:23 AM miss0r: I know the importance of that. I know a plane mechanic
01:23 AM XXCoder: yeah no deaths or anything but can be worse
01:23 AM miss0r: yeah
01:23 AM miss0r: I've never met a guy as meticulous about his tools :D
01:23 AM XXCoder: I bet
01:24 AM XXCoder: I'd be also
01:24 AM miss0r: yeah
01:24 AM XXCoder: packers was certainly careful
01:24 AM miss0r: I have a tool kit I use for mill gearboxes. everything is labeled and printed in the case, so I am sure not to loose anything. but this guy is on another level :D
01:25 AM miss0r: like two brainwaves short of tatooing his checklist to his arm
01:25 AM XXCoder: i bet guy made inserts for every took
01:25 AM XXCoder: best way to spot missing tool
01:26 AM CaptHindsight: miss0r: over here we would have to do all that in conduit :)
01:26 AM miss0r: I know theres a perfectly good reason for it. even cases to prove so. but from the outside looking in, it seems borderline OCD
01:26 AM XXCoder: yeah
01:26 AM Deejay: moin
01:26 AM XXCoder: hey
01:26 AM miss0r: CaptHindsight: conduit?
01:26 AM miss0r: morning
01:27 AM CaptHindsight: https://i.redd.it/i0a5xw2ftkk21.jpg
01:27 AM XXCoder: art
01:27 AM miss0r: ahh.. well, that container was only a temporary thing :)
01:27 AM miss0r: it ran for 6 months, then was scrapped :D
01:28 AM miss0r: they had to rebuild a sewage pumping/cleaning station. so this had to control all the temporary pumps they sat in place to remove the station and start over.
01:28 AM CaptHindsight: electric toothbrush charging stations?
01:29 AM CaptHindsight: ah
01:29 AM miss0r: hehe, I bet with all the radiation from those VLCs you could probably charge a toothbrush ;D... ABB has some issues with sheilding
01:29 AM miss0r: the big ones are 120kva and the smaller ones are 60kva
01:31 AM miss0r: I'm getting better at typing. but with my right arm covered with plaster, this still takes some getting used to...
01:31 AM XXCoder: ow
01:37 AM CaptHindsight: miss0r: did you break the arm?
01:39 AM miss0r: CaptHindsight: my right thumb
01:39 AM CaptHindsight: oh no
01:39 AM miss0r: hand cranking my 'ol land rover...
01:39 AM miss0r: hand slipped at exactly the wrong moment, and it backfired
01:40 AM miss0r: I had cold fingers so I didn't feel it until later
01:40 AM CaptHindsight: i wacked mine pretty hard last year, had a lump on the bone for a few weeks
01:40 AM miss0r: but then I felt it with a vengance :)
01:40 AM miss0r: yeah. That happens :D
01:42 AM miss0r: CaptHindsight: I've had bumps like that before. I don't nessesarily thing it means a break
01:43 AM miss0r: but it hurts like hell
01:43 AM CaptHindsight: yeah was sore for several days, I didn't xray
01:43 AM miss0r: same goes for me. but this time it had a strange tingling feeling added to the mix
01:44 AM miss0r: which is why I decided to have it checked out
01:44 AM miss0r: but I must say, I was VERY pleased about speed of which the hospital handled it.
01:44 AM CaptHindsight: how long will the cast be on?
01:44 AM miss0r: 4 weeks
01:45 AM miss0r: well.. I'm going for a checkup wensday. I am seriously considering leaving without the cast. this thing is driving me nuts!
01:46 AM miss0r: I know its there for a reason.. but its not like the finger is snapped in two. its just a chip broken off
01:46 AM miss0r: and if I could do some carefull tasks at home WITHOUT the cast, I would me much less likely to go ape shit in the near future
02:07 AM Loetmichel: hehe, i once got my left leg xrayed because of a nail thru the calf, they were searching for debris. Do looked at the xray: Do you know that your little toe looks to have ben broken at least half a dozen times? @miss0r
02:08 AM Loetmichel: <- had no idea
02:08 AM miss0r: lol I would not be surprised
02:08 AM miss0r: That thing has no point other than to cause you pain when bumped against a table leg
02:08 AM Loetmichel: indeed
02:09 AM Loetmichel: but in my case it was the door frame in the loong hall at my parents flat
02:09 AM miss0r: hehe
02:09 AM Loetmichel: that was about 2" smaller on each side than the hallway
02:09 AM miss0r: still burned into your memory, eh? :D
02:10 AM Loetmichel: yeah, i hit that in full run quite a few times
02:10 AM miss0r: my toes are cringing just thinking about it
02:11 AM miss0r: at the moment I am just waiting for the postal service to drop off some items so I can continue on my emco lathe retrofit.!
02:11 AM miss0r: I hate waiting :) and I am two inches short of cabin feaver here
04:46 AM lag_ is now known as lag
05:09 AM JT-Cave: morning
05:11 AM XXCoder: yo
05:40 AM Tom_L: morning

10:27 AM mrec: https://youtu.be/wroubVDy0nM?t=268 hahaha
10:27 AM gregcnc: never done that?
10:28 AM mrec: no never
10:28 AM gregcnc: I have power cross feed, so I wouldn't normally.
10:28 AM gregcnc: but when trying to get a nice taper with the compound, this does the trick. I just use a socket on the hex nut
10:29 AM mrec: I'm about to order a baby lathe from china I hope I can part 20mm steel properly with it
10:29 AM mrec: I somewhat think that the compound has to go away too
10:29 AM gregcnc: by baby you mean 10-12" swing?
10:30 AM gregcnc: were you the one having trouble parting a few months ago?
10:30 AM mrec: https://www.weissmachinery.com/variable-speed-lathe/57289250.html
10:30 AM mrec: no
10:31 AM mrec: I only put together my CNC mill the last months, that one works fine (also for cutting steel)
10:31 AM mrec: also a baby mill
10:31 AM gregcnc: ok, someone had one of these (7x10) and had a hard time
10:31 AM mrec: did you remove the compound?
10:32 AM mrec: I have one in Europe .. but instead of shipping it to Taiwan I better buy another one
10:32 AM gregcnc: I don't have one
10:32 AM mrec: that lathe costs 570$
10:32 AM mrec: shipping I guess 150$
10:32 AM gregcnc: can't you source from china?
10:33 AM gregcnc: or locally even?
10:33 AM mrec: I'll get it directly from CN
10:33 AM mrec: Taiwan only has high quality stuff here
10:34 AM mrec: and expensive of course.
10:40 AM mrec: I'm getting closer and closer to my pinions I need the lathe to cut them off the steel bar
11:52 AM Roguish: good morning....
12:30 PM norias: wee
01:23 PM Thorhian: Anybody got recomendations on rotary switches for a CNC Control panel along with a rotary encoder for jogging the machine. I can find plenty of cheap crap out there but anyone got any recomendations?
01:25 PM Tom_L: selector switches?
01:25 PM Tom_L: yes
01:27 PM Tom_L: https://www.ebay.com/itm/1PCS-Engraving-Handwheel-CNC-Manual-Pulse-Generator-MPG-6-Terminal-5V-60mm-New/264630981964?hash=item3d9d3c554c:g:YPUAAOSw10FeQsog
01:27 PM Tom_L: i think that's the one i have or very similar
01:29 PM Thorhian: That is a decent looking jog wheel. What did you use for rotary switches? I want physical ones to select how fast the jog wheel moves the machine along with axis selection.
01:29 PM Tom_L: looking
01:31 PM Tom_itx: alpha SR2612F-0112-21R0B-D8-N

01:33 PM Tom_L: there are several MPG listed on ebay all similar
01:37 PM unterhaus: winders has this new trick where they have a notification but don't tell you what it is
01:37 PM Tom_L: it's on a need to know basis and you don't need to know
01:38 PM gloops: nice when microsoft installs 'updates' without asking
01:40 PM Thorhian: I've delegated windows to a VM. Linux only runs on bare metal now. So glad I've cut ties with M$ for my main computer needs.
01:46 PM roycroft: i've only run windows in vms for years, but that makes the update problem even worse
01:47 PM roycroft: microsoft let one defer (but not totally cancel) updates to windows 10, but after a while one can no longer defer
01:47 PM roycroft: if i figure up a vm every couple months or so it almost aleays goes into "force update" mode
01:47 PM roycroft: but not at boot time
01:47 PM roycroft: no, it waits until i have opened the app that i need to use and start doing work
01:48 PM roycroft: it knows when i'm at a critical point and i'm about to do a save, and forces its update on me seconds prior to the save
01:52 PM roycroft: i've looked up and applied registry settings to stop the updates, and they work for a while, but eventually windows gets lonely and insists on calling home no matter what

01:54 PM -!- #linuxcnc mode set to +v by ChanServ
02:42 PM roycroft: folks, my air system is vastly improved after the work i did this weekend, but i still have a 50' air line on a reel that is past the inline air filter, and is still blowing out water, after blowing air though it for a good 20 minutes or so
02:43 PM roycroft: is there something i can do that i'm not thinking of to finish drying it out, or do i just need to put another filter right at the tool end of the line for a while?
02:44 PM gregcnc: other than removing the water?
02:44 PM norias: blow hot air through it?
02:44 PM gregcnc: If the air isn't dry, it will drop out somewhere
02:46 PM roycroft: the source of most of the water has been fixed
02:46 PM roycroft: the compressor tank probably still has a fair amount of water in it, though
02:46 PM roycroft: but i can easily drain it daily now
02:46 PM roycroft: and i shall
02:46 PM roycroft: it's just going to be wet for a while
02:47 PM gregcnc: it will always be wet
02:47 PM roycroft: yes, i should say it's going to be wetter than usual for a while
02:47 PM gregcnc: does this compressor have an after cooler?
02:47 PM roycroft: i installed a new filter downstream
02:47 PM roycroft: no, and i can't afford one right now
02:47 PM roycroft: neither the cost of the after coolor nor, more importantly, the space to install it
02:48 PM roycroft: the system ran fine for years until recently
02:48 PM gregcnc: what changed?
02:48 PM roycroft: i'd been draining the tank fairly regularly, and not getting a lot of water each time
02:48 PM roycroft: i thought i was fine
02:48 PM roycroft: but then it started blowing out a lot of water
02:48 PM roycroft: i "drained" it again
02:48 PM roycroft: and got about 250ml of water
02:49 PM roycroft: then i decided that i wanted to install a better drain system
02:49 PM roycroft: and as soon as i started messing with the old one, i found that the drain was fairly clogged
02:49 PM roycroft: i drained about 150l of water on saturday
02:49 PM gregcnc: so it was never really dry
02:49 PM roycroft: the tank was mostly water
02:50 PM roycroft: no, but it was not blowing out streams of water before
02:50 PM roycroft: anyway, i have a new drain system
02:50 PM roycroft: that should not clog
02:50 PM roycroft: and very easy access to drain it daily
02:50 PM gregcnc: the cold water was your after cooler
02:50 PM roycroft: i suppose
02:50 PM gregcnc: it was condensing a lot of water
02:50 PM roycroft: yes, it would have condensed a lot of it
02:50 PM roycroft: so now i have a mostly empty tank
02:51 PM gregcnc: if you check the tank after this 20 minutes is the tank warm?
02:51 PM roycroft: the air coming out just past the filter is fairly dry
02:51 PM roycroft: i have not checked since draining it
02:51 PM roycroft: i'd anticipate the top of the tank, at least, would be warm
02:52 PM roycroft: it's just this last hose that doesn't seem to want to blow the water out completely
02:52 PM gregcnc: if there is water in the air, it may never
02:52 PM JT-Shop: lay the hose out flat then blow the water out
02:52 PM roycroft: yeah, i should probably do that
02:52 PM roycroft: just take it off the reel, lay it on the ground, and blow it out that way
02:53 PM roycroft: i'm going for getting rid of most of the water
02:53 PM roycroft: when i use things like paint guns that have to be really dry, i put a dessicant filter right before the gun
02:54 PM gregcnc: a
02:54 PM gregcnc: ok
02:54 PM roycroft: most of the other air tools are cheap tools, and i add a couple drops of oil to them before i use them
02:55 PM roycroft: so for me, bone dry is not essential for that stuff
02:55 PM gregcnc: If the tank warms and contains humid air, it will drop out down the line
02:55 PM roycroft: yeah, i know i'm never going to eliminate all of the condensation
02:55 PM gregcnc: if the tank is cool enough a lot will condense in the tank
02:56 PM roycroft: and this is february, when the humidity is highest
02:56 PM roycroft: the humidity is 97% at the moment
02:56 PM roycroft: my air will be a lot more dry in july
02:56 PM gregcnc: but temps are low so specific humidity is low
02:57 PM roycroft: it's 12 degrees
02:57 PM roycroft: far from hot
02:57 PM roycroft: but not cold
02:57 PM roycroft: that's 12 real degrees, not 12 archaic american degrees :)
02:57 PM roycroft: about 55f, iirc
02:57 PM gregcnc: right ti's just a math problem
02:58 PM roycroft: ideally i'd have an after cooler
02:58 PM roycroft: and i've wanted one for a long time
02:58 PM roycroft: it's that i have nowhere to put it
02:58 PM gregcnc: small tanks have bigger problems. I had a 10 gallon and with 50% duty cycle it would warm up and blow water,
02:59 PM gregcnc: even with after cooler, and two traps
03:00 PM roycroft: i do have kind of an aftercooler, btw
03:00 PM gregcnc: now, I have refrigerated dryer on the pump
03:01 PM roycroft: i replaced the air line from the compressor pump outlet to the tank with a coil of 3/4" copper tubing, and run a fan across that coil while the compressor is running
03:01 PM roycroft: that's far from totally effective, but it drops the temperature by a fair amount
03:02 PM gregcnc: do you have something to catch that water?
03:02 PM roycroft: no
03:02 PM gregcnc: I had a filter with auto drain before the tank
03:03 PM roycroft: i'm thinking about an autodrain on the tank itself
03:03 PM roycroft: that would not keep water from getting into the tank, of course
03:03 PM roycroft: but it would help prevent 150l of water from filling up the tank
03:03 PM roycroft: but the new drain setup is so easy to use i may not bother
03:04 PM roycroft: the original drain was a bit of 1/8" copper tubing that went into a needle valve that was mounted to the rear of the tank
03:04 PM roycroft: and the valve outlet was just above ground level
03:05 PM roycroft: to drain it i'd have to move a bunch of stuff around, lay down on the floor, hold a tiny tray underneath the outlet, drain off a little water, empty the tray, repeat until done
03:05 PM roycroft: it really sucked
03:05 PM roycroft: so i would only drain every couple months or so
03:05 PM roycroft: i just replaced that with a 1/2" drain (although the outlet itself is currenly 1/4" - i'll fix that later)
03:06 PM roycroft: it comes out the front, and i put a boiler drain valve on it
03:06 PM roycroft: i just have to bend down and open the valve, holding a big cup underneath it
03:06 PM roycroft: and i can connect a hose easily if i want
03:07 PM roycroft: i wonder if i can find an affordable aftercooler that can live outdoors
03:07 PM roycroft: i have room on the outside of the lean-to where the compressor lives to install one
03:10 PM gregcnc: any favorite shop coat? i'm tired of coolant all over everything
03:13 PM roycroft: what about this setup as an aftercooler?
03:13 PM roycroft: https://www.youtube.com/watch?v=RutBpkvSG_M
03:13 PM roycroft: i have wall space for that by the compressor
03:15 PM gregcnc: I did an ebay heat exchanger, but this was for a 2HP pump
03:15 PM roycroft: mine is 5hp
03:15 PM roycroft: i don't recall the exact specs, but i think it's in the range of 140cfm @135psi
03:16 PM roycroft: maybe a bit less on the volume
03:16 PM roycroft: finned tubing would be nice, but that stuff is wicked expensive
03:17 PM gregcnc: https://www.ebay.com/itm/NEW-Lytron-TF6945G3-21-Rev-B-300-PSI-Heat-Exchanger-Hoses-Quick-Release-Gates/193870167920?hash=item2d238fff70:g:uCwAAOSw2H1eDWns
03:17 PM gregcnc: that's huge, but stuff like that
03:17 PM roycroft: i just wonder how effective that system in the video i linked to is
03:17 PM gregcnc: it all depends on actual temperatures
03:18 PM gregcnc: if the pipe gets hot, it stops working
03:18 PM roycroft: yes, and the heat exchanger would have to be right next to the compressor, which is not ideal
03:18 PM roycroft: or it would have to be just outside on the other side of the wall
03:19 PM roycroft: but it's a southenrn-facing wall that is not shaded
03:19 PM roycroft: also not ideal in the summer
03:20 PM roycroft: but i went over 20 years without an after cooler and everything was fine until recently
03:21 PM roycroft: so if i ever get the water out of this hose i might be fine again
03:21 PM roycroft: and maybe, since the hose is 20+ years old, it's time to replace it anyway
03:21 PM gregcnc: maybe it will take another 20 years to fill the tank with water
03:22 PM roycroft: well, i'll be draining it regularly now, and this new drain should not clog
03:22 PM roycroft: in 20 years i'll probably be too old to be able to work on a compressor
04:33 PM * JT-Shop goes to work on the workbench
04:40 PM perry_j1987: looking into these 7i96 boards, what pin is used for pwm
04:47 PM pcw_home: it depends on the firmware, one option is to steal stepgen 4 for PWM and DIR
04:48 PM pcw_home: another option is to have PWM on the expansion connector (for BOBs with analog outputs)
04:49 PM perry_j1987: its got the 4+1pwm firmware
04:50 PM pcw_home: that's the one with PWM/DIR on the Stepgen4 connections
04:55 PM perry_j1987: ok and the config tool doesnt let you edit the num of pwm generators
04:55 PM perry_j1987: or is it counting from 0 = 1
04:56 PM perry_j1987: ah its just got one option for firmware dropdown 7i96d
04:58 PM JT-Shop2: which config tool?
04:58 PM perry_j1987: pncconf
04:58 PM JT-Shop2: ok, mine is better behaved I think
05:00 PM perry_j1987: got that one
05:01 PM perry_j1987: had to install 1.1 to get it to launch
05:01 PM JT-Shop2: 1.1?
05:01 PM perry_j1987: 7i96 configuration tool
05:02 PM JT-Shop2: did you download the .deb?
05:02 PM perry_j1987: ya
05:04 PM JT-Shop2: 1.2.4 is the current version
05:05 PM perry_j1987: i'll try it
05:07 PM perry_j1987: worked this time
05:08 PM perry_j1987: some more options in spindle type dropdown now
05:08 PM JT-Shop2: yup, been working on it a lot
05:08 PM perry_j1987: there's PWM Direction and then Direction PWM
05:09 PM JT-Shop2: ya 4 different modes
05:09 PM perry_j1987: 6 opens in the dropdown
05:13 PM JT-Shop2: working on step and direction spindles
05:13 PM JT-Shop2: pwm is 4
05:13 PM JT-Shop2: and on/off spindles
05:14 PM perry_j1987: step and dir spindles like those using nema34's and such?
05:16 PM perry_j1987: encoder scale is greyed out even though machine tab lists encoder 1
05:16 PM JT-Shop2: yes and still working on encoder feedback spindles
05:17 PM perry_j1987: ok so i'll have a few manual things to stitch together in the configs afterwards?
05:18 PM JT-Shop2: for an encoder yes, any feedback you can provide will help make the tool better
05:18 PM perry_j1987: first thing that comes to mind
05:18 PM perry_j1987: the pins/terminals tab
05:19 PM perry_j1987: if that changed the pins to show PWM
05:20 PM JT-Shop2: yea that would be a good thing
05:21 PM JT-Shop2: just sent myself a note
05:21 PM perry_j1987: it could exclude the spare joint tabs in Axis section if they are not specified in Machine tab
05:22 PM JT-Shop2: not sure I follow
05:23 PM perry_j1987: ie if you have a lathe your only using 2 axis
05:23 PM perry_j1987: so joint 0 and joint 1 are the only tabs that "need" to show in that case
05:23 PM Tom_L: lathe _could_ have more depending how fancy it was
05:23 PM JT-Shop2: but you don't specify machine type on the machine tab
05:24 PM perry_j1987: ya but then you'd have more coordinates specified in machine tab right?
05:24 PM JT-Shop2: I try not to put any limits on making a configuration
05:24 PM JT-Shop2: no
05:24 PM Tom_L: especially since they opened up 'spindles' and 'joints'
05:24 PM perry_j1987: ok fair enough
05:24 PM JT-Shop2: you could have a XCA machine
05:24 PM JT-Shop2: XU
05:24 PM JT-Shop2: what ever you want
05:25 PM Tom_L: it would be next to impossible to code every combination
05:25 PM JT-Shop2: you could have X with 5 joints if you want
05:26 PM XXCoder: perry_j1987: depends. I saw lathe with 3 axis
05:26 PM Tom_L: naw i just want ice cream
05:26 PM * JT-Shop2 goes to tuck the chickens in and read them a bed time story
05:26 PM perry_j1987: the little mill that could?
05:26 PM perry_j1987: heh
05:26 PM JT-Shop2: and you could do that with my tool
05:29 PM perry_j1987: so what do i have to do manually to finish getting the encoder going after generating the config
05:30 PM Tom_L: http://linuxcnc.org/docs/2.8/html/drivers/hostmot2.html#sec:hm2-encoder
06:07 PM perry_j1987: it appears i have to redo the wiring on my limit switches for this mesa board
06:08 PM perry_j1987: i only see options for home & limit + specify what joint it belongs to
06:08 PM perry_j1987: right now i have all of them wired in series x and z
06:15 PM JT-Cave: what do you need?
06:15 PM perry_j1987: i can split it up np
06:15 PM perry_j1987: i just had them going into one input on the BOB before
06:15 PM JT-Cave: btw I just uploaded a new deb that should do spindle encoder etc
06:16 PM perry_j1987: ohhhh :)
06:16 PM perry_j1987: looking now
06:16 PM JT-Cave: both x and z home
06:16 PM JT-Cave: ?
06:16 PM perry_j1987: ya
06:16 PM perry_j1987: stepconf had option for all home +limits
06:16 PM JT-Cave: hmm
06:16 PM JT-Cave: ok I can add that then
06:17 PM perry_j1987: was a way to save inputs on that BOB so i had room for the encoder etc
06:17 PM perry_j1987: not needed so much for the 7i96 though
06:18 PM JT-Cave: ok
06:19 PM perry_j1987: so the encoder scale i ahve a 1000/4000 encoder
06:19 PM perry_j1987: do i put 4000 in that field?
06:20 PM perry_j1987: ah nice you even got the PWM thing going on Pins tab
06:20 PM JT-Cave: lol ya
06:21 PM JT-Cave: pulses per rev
06:22 PM perry_j1987: on the config file generated the .ini
06:22 PM perry_j1987: towards the top VERSION = 1.1
06:22 PM JT-Cave: I had the pwm thing on the pins tab almost done
06:22 PM perry_j1987: is that your tool's version or something else
06:22 PM JT-Cave: linuxcnc version so Andy's script doesn't bug you
06:23 PM JT-Cave: change it to anything else and run the script lol
06:23 PM Tom_L: JT-Cave, any hickups with the range?
06:24 PM JT-Cave: too crowded to go see, parking lot is full most days
06:24 PM Tom_L: hah that's a good sign
06:24 PM JT-Cave: yep
06:25 PM JT-Cave: got to a bit of robot programming tomorrow then off to the spoke machine automation
06:25 PM JT-Cave: got most of the spoke machine conversion drawn up
06:26 PM JT-Cave: I don't charge him my normal rate as he is a small business so he gets my children's rate lol
06:26 PM Tom_L: nice
06:27 PM Tom_L: kindof a challenge on that old equipment
06:28 PM JT-Cave: yea pretty interesting for sure
06:29 PM JT-Cave: for a bigger company I'd charge twice or more what I'm charging him
06:32 PM JT-Cave: dunno about you but I'm ready for some warmer temps to arrive
06:34 PM JT-Cave: time for some rabbit food
06:56 PM Tom_L: it's been pretty nice here last couple days
07:04 PM perry_j1987: well i think i might be ready to go test this thing out
07:05 PM roycroft: it's raining like crazy here, but it's reasonably warm so that is good
07:05 PM roycroft: and it's not july or august, so rain should be no surprise
07:06 PM perry_j1987: ah actually so these g320x drivers for step and dir and then there's a source pin you pull high or low
07:07 PM perry_j1987: so if that is pulled high on the g320x drivers what would i wire the step/dir into on this 7i96 the - or + dir/step pins?
07:07 PM perry_j1987: never had board with both options before
07:21 PM unterhaus_: what is the function of the source pin?
07:31 PM CaptHindsight: we finally got a big dump of snow and below 0F temps on the way in a few days
07:31 PM CaptHindsight: been pretty mild here untilnow
07:33 PM unterhaus_: the g320 source looks like it decides if the step/dir is active high or low. I would go active low if given a choice
07:35 PM CaptHindsight: unterhaus_: don't use active low for DIR CW and CCW :)
07:38 PM CaptHindsight: perry is gone but this makes it really clear: https://www.geckodrive.com/support/g320x-stepdir-interface.html
07:38 PM CaptHindsight: The G320X uses a universal optoisolator interface polarity circuit. The 'COMMON' terminal (term. 10) may be ground-referenced or 5VDC-referenced.
07:38 PM CaptHindsight: The STEP and DIRECTION inputs are pull-down loads when COMMON is connected to controller GND.
07:38 PM CaptHindsight: The STEP and DIRECTION inputs are pull-up loads when COMMON is connected to controller +5VDC.
07:41 PM unterhaus_: didn't I say that without so much detail?
07:41 PM CaptHindsight: When using COMMON connected to +5VDC:
07:41 PM CaptHindsight: Use narrow logic '0' step pulses.
07:41 PM Tom_L: sounds similar to how the mesa optos are set up
07:42 PM Tom_L: for source or sink
07:42 PM CaptHindsight: unfortunately the geckodrive info avoids use of the terms "active low" and "active high"
07:43 PM unterhaus_: yeah, and it's also unforctunatelthey call it source and common
07:44 PM CaptHindsight: yeah it's OK to offer a dumbed down explanation as long as you also start with the common terms and expressions
07:45 PM unterhaus_: can mesa choose between active high/low?
07:46 PM CaptHindsight: you can flip the polarity of the signals in the HAL file
07:49 PM CaptHindsight: the 7i77 "includes 32 sinking inputs and 16 sourcing outputs"
07:49 PM Tom_L: the darlingtons ( i think they are ) can also be connected to GND or +V
07:49 PM Tom_L: on the back side of the optos
07:49 PM CaptHindsight: depends on the IO board
07:49 PM Tom_L: right
07:50 PM Tom_L: i flipped some around on mine
07:51 PM unterhaus_: the board perry has is equipped with + and - step/dir outputs
07:51 PM unterhaus_: that's what he was asking about
07:51 PM Tom_L: i know
07:51 PM unterhaus_: so if common/source is 5 volts, he wants -
07:51 PM unterhaus_: and vice versa
07:51 PM unterhaus_: too bad he's not here to see all this brilliance
07:52 PM Tom_L: maybe the log is working for a change
07:53 PM Tom_L: seems so
07:53 PM Tom_L: he's back anyway
07:57 PM unterhaus_: you think he knows we were talking about him?
08:30 PM perry_j1987: hey guys
08:30 PM perry_j1987: do i use the + or - on the step/dir with these g320x drivers and 7i96 board
08:30 PM Tom_L: read the log
08:30 PM perry_j1987: i was driving
08:31 PM perry_j1987: on very bad internet hotspot out at the shop i cant load browser
08:36 PM unterhaus_: connect step- dir- from mesa. Then hook common/source to 5v
08:36 PM perry_j1987: ty
08:50 PM perry_j1987: hmm the encoder goes into - or +
08:51 PM perry_j1987: i got a,b,z 5v,gnd
08:57 PM Tom_L: i'd guess + on a & b and z if you have an index channel
09:06 PM perry_j1987: k
09:18 PM norias: bah
10:09 PM perry_j1987: do the limit switches need to go to input common for the other leg
10:09 PM perry_j1987: or can they just go to ground
10:10 PM Tom_L: i'd say 'signal' gnd
10:11 PM Tom_L: which ends up in the same place but i'd put it close to the board
10:11 PM perry_j1987: pin 12 on TB3
10:15 PM perry_j1987: ok
10:15 PM perry_j1987: im getting close to getting everything in here
10:16 PM perry_j1987: the err/reset pins on these g320x drives what should i do with these
10:16 PM Tom_L: you want it so a broken wire will trip a limit too
10:16 PM perry_j1987: i've just manually been enabling the drives
10:16 PM Tom_L: i did that for a long time but i've got enable wired thru the estop circuit now
10:17 PM Tom_L: 2, one for the drives and a separate one for the spindle
10:25 PM perry_j1987: ok
10:26 PM Tom_L: i did a little rewiring when i got my vfd for the new spindle motor
10:36 PM skunkworks: https://www.youtube.com/watch?v=Gx263nnTrqY
10:37 PM Tom_L: how many have you printed?
10:37 PM Tom_L: the extra parts say more than one :)
10:38 PM skunkworks: it has gone through a few design revisions..
10:38 PM Tom_L: what's the ratio?
10:39 PM Tom_L: and does the plastic get warm from the friction?
10:39 PM skunkworks: 100 to 1
10:39 PM skunkworks: I will check - been running for about 30 minutes
10:40 PM skunkworks: brought the hb04 pendon up with me in case I need to stop it from a distance...
10:40 PM skunkworks: I figure it is running about 850rpm
10:40 PM skunkworks: by the rotation of the harmonic drive
10:42 PM skunkworks: doesn't seem to get warm
10:42 PM Tom_L: nice
10:43 PM skunkworks: using vasoline..
10:45 PM skunkworks: quite a bit of wind though
