01:06 AM Deejay: moin
01:45 AM lcnc-relay: <zmrdko (@_discord_397707718582075420:jauriarts.org)> 👋 hello, how do I get delayed pulse signal in HAL? I am trying to do estop reset in two stages, since to my VFD drive it takes a while to get out of STO
01:46 AM lcnc-relay: <zmrdko (@_discord_397707718582075420:jauriarts.org)> Im looking into timedelay, oneshot, tp, ton, tof, but nothing is accomodated to pulse signal
04:07 AM Tom_L: morning
04:11 AM Tom_L: zmrdko, http://linuxcnc.org/docs/stable/html/man/man9/timedelay.9.html
04:12 AM Tom_L: i used that on some relays i wanted spaced apart a small amount
04:16 AM Tom_L: classicladder would probably work
04:16 AM Tom_L: https://linuxcnc.org/docs/devel/html/ladder/ladder-examples.html
04:17 AM Tom_L: gives an estop pulse example
04:20 AM Tom_L: timedelay has on-delay and off-delay which may do what you want
04:32 AM JT-Cave: morning
08:00 AM lcnc-relay: <zmrdko (@_discord_397707718582075420:jauriarts.org)> Thanks Tom, but for timedelay, if input is only short pulse, it does nothing. It requires the input to be longer than on-delay. I hopefully solved it hooking oneshot in between
08:02 AM JT-Cave: you can do a one shot latch in classic ladder
08:04 AM JT-Cave: just use the output to latch the timer in
08:30 AM Tom_L: JT-Cave, pr #73
08:46 AM JT-Cave: thanks
08:54 AM Tom_L: JT's brake & alignment shop open for business?
09:27 AM JT-Cave: shortly
09:27 AM JT-Cave: gotta clean chicken shit first
09:34 AM JT-Cave: working on a new ui for the bp
09:34 AM Tom_L: nice
09:43 AM lcnc-relay: <skunkworks8841> Just had 4 tires put on the jetta.. I put close to 40k on them since I got it running and the rears were cupping really bad. (really loud) the mechanic called me and was wondering if the car was in an accident because the rears were way off.
09:43 AM lcnc-relay: <skunkworks8841> I know I hit a curb a few times making right turns.. Maybe I tweeked it
09:43 AM lcnc-relay: <JT> https://jauriarts.org/_matrix/media/v3/download/matrix.org/QyvVhXczdHSFvfCmaQAmASBQ/20240831_093639_613028314448011164.jpg
09:43 AM JT-Shop: the touch screen is a bit high so trying to put all the controls at the bottom
09:44 AM lcnc-relay: <skunkworks8841> cool!
09:44 AM JT-Shop: so far I have about 15 minutes into creating the ui :)
09:51 AM Tom_L: need a closeup
09:54 AM lcnc-relay: <JT> https://jauriarts.org/_matrix/media/v3/download/matrix.org/zvarSfBAHrnuaeElwqwHKClq/20240831_094732_4600175073288218868.jpg
09:54 AM * JT-Shop just loves how Flex remembers the size and location of the screen
09:55 AM Tom_L: where you showing the gcode?
09:55 AM Tom_L: gcode tab..
09:55 AM Tom_L: nevermind
09:57 AM Tom_L: you broke flex
09:57 AM -!- #linuxcnc mode set to +v by ChanServ
09:58 AM Tom_dev: http://paste.debian.net/1328060/
09:58 AM Tom_L: lemme make sure current is installed
09:59 AM Tom_L: yeah it's broke
10:05 AM JT-Cave: your ini file is not correct it's supposed to be comma separated
10:05 AM Tom_L: what section?
10:05 AM JT-Cave: or paste the increments you have
10:05 AM JT-Cave: display
10:07 AM JT-Cave: INCREMENTS = 1 mm, .5 in, ...
10:07 AM Tom_L: you changed that then
10:07 AM JT-Cave: but I need to test for incorrect ini and yes I fixed that
10:07 AM Tom_L: that took care of that one
10:07 AM Tom_L: need to check the rest
10:08 AM Tom_L: and probably post the fixes
10:09 AM JT-Cave: and I'll test for an incorrect increments value
10:09 AM * JT-Cave goes to open the brake shop
10:14 AM JT-Woodshop is now known as JT-Brake
10:15 AM JT-Brake is now known as JT-Brake_Shop
10:15 AM Tom_L: #74 up for that
10:17 AM JT-Brake_Shop: I'll merge that as soon as I'm done using the old ones to perfect the test
10:18 AM Tom_L: double checked that they all run now too
10:20 AM Tom_L: oops i missed one
10:45 AM JT-Brake_Shop: I'm glad you found that, it makes Flex that much better
10:46 AM * JT-Brake_Shop takes a peek at the RR parking brake before assembly
11:18 AM JT-Brake_Shop: RR rotor TIR 0.004" time for a break then a nap
11:19 AM JT-Brake_Shop: C3's have fixed calipers and hubs are "roughly" machined so you have to try all 5 positions for the rotor and pick the best one...
11:37 AM JT-Shop: nap time
12:15 PM Tom_L: agreed
12:16 PM Tom_L: just defrosted a deep freeze
12:20 PM rdtsc: just got PlayOnLinux installed, to use Wine, to use QucsStudio, to test a "latching power idea", for the mill, to add "manual power-on" and "auto power-off" capability to the 7C80, to get 1/1000th closer to completion
12:20 PM rdtsc: the level of indirection is staggering
12:56 PM JT-Shop: time to start on the LR caliper removal
12:58 PM Tom_L: is the rear the hardest?
01:04 PM JT-Shop: I'd "think" they are the same
01:04 PM JT-Shop: let you know when I'm done... trying to carefully remove the brake lines on the LR now
01:17 PM BorgPipe: https://i.imgur.com/k4sdgxq.jpeg
01:19 PM JT-Shop: using thermal shock and break free on the steel to steel joints, so far it's working
01:22 PM JT-Shop: Tom_L, gotta tweak the touch for the BP with the tabs on the bottom and I think that blank spot will be the DRO and turn off the plotter DRO
01:23 PM Tom_L: flexible
01:28 PM Tom_L: likely the first time those brakes have been apart
01:28 PM Tom_L: especially from the look of that one pad
01:34 PM JT-Brake_Shop: nope, the rotors are not original
01:34 PM Tom_L: hmm
01:34 PM JT-Brake_Shop: the factory rotors were riveted to the hubs
01:34 PM Tom_L: pita
01:34 PM JT-Brake_Shop: glad I didn't have to drill them off lol
01:35 PM Tom_L: or a grinder
01:35 PM JT-Brake_Shop: even the shop manual says not to rivet new ones on so they don't come with the rivet holes
01:35 PM JT-Brake_Shop: drill is the only option
01:35 PM Tom_L: oh
01:35 PM Tom_L: studs in the way probably
01:35 PM JT-Brake_Shop: the heads are recessed
01:36 PM Tom_L: yeah that surface has to be flat for the wheel
01:39 PM * Tom_L goes for the nap he never got
01:44 PM JT-Brake_Shop: got one hose end off...
02:45 PM Tom_L: those things must really be a mess
03:36 PM JT-Shop: finally got the LR hoses off
03:36 PM JT-Shop: https://radar.weather.gov/station/kpah/standard
03:37 PM JT-Shop: a bit moist here
03:57 PM Tom_L: we got 2" couple days ago and 3 a couple before that
03:58 PM JT-Shop: we might have gotten 1/2"
03:58 PM Tom_L: i was just out and enptied the rain gage
03:59 PM JT-Shop: got the LR caliper off so now I just need to check the rotor and see what the TIR is
03:59 PM Tom_L: are they flat?
03:59 PM Tom_L: or riged
04:00 PM JT-Shop: the rotors?
04:00 PM Tom_L: yeah
04:00 PM JT-Shop: they are flat, take a photo in a bit
04:00 PM Tom_L: sometimes you can turn them depending how much is wore off
04:00 PM JT-Shop: but you have to make sure the TIR at 1" from the edge is < 0.007"
04:01 PM JT-Shop: they are still 1.250" which is stock
04:01 PM xxcoder: interesting yorkshire today
04:04 PM Tom_L: mitutoyo is having another sale
04:06 PM -!- #linuxcnc mode set to +v by ChanServ
04:06 PM Tom_L: 'quantumike'
04:07 PM Tom_dev: https://www.mitutoyo.com/quantumike-special-promotion/?utm_term=explore-now&utm_campaign=fy20_mitutoyo_quantumike&utm_content=promotion-quantumike&utm_source=act-on&utm_medium=email&cm_mmc=Act-On%20Software-_-email-_-Fast%20Measurements%20%2526%20Faster%20Savings%3A%20Up%20To%2020%2525%20Off%20QuantuMike%20Special%20Promotion%21-_-Explore%20The%20Mitutoyo%20QuantuMike%20Promo
04:07 PM Tom_L: fast movement
04:07 PM JT-Shop: https://www.mitutoyo.com/quantumike-special-promotion/?utm_term=explore-now&utm_campaign=fy20_mitutoyo_quantumike&utm_content=promotion-quantumike
04:08 PM Tom_L: yeah that one :)
04:08 PM JT-Shop: you need drop everything after the ?
04:08 PM * JT-Shop almost never uses a micrometer any more
04:08 PM Tom_L: me either not that often
04:08 PM JT-Shop: I don't even keep batteries in them
04:18 PM Tom_L: i would on those calipers though since they could have a lip
04:19 PM JT-Shop: I checked for a lip with a straight edge and didn't see or feel one
04:19 PM JT-Shop: the rotors look pretty new
04:19 PM JT-Shop: dunno what I'll find on the front lol
04:19 PM Tom_L: which one had the horrible looking pad?
04:29 PM JT-Cave: RR
04:30 PM Tom_L: generally the front wear quicker
04:31 PM Tom_L: wonder what those will look like
05:02 PM JT-Brake_Shop: judging from the LR they "could" be in decent shape
05:12 PM lcnc-relay: <JT> https://jauriarts.org/_matrix/media/v3/download/matrix.org/LKAQnkbmJQErbVrwHDtUNfpO/1000002308.jpg
05:24 PM JT-Brake_Shop: LR TIR 0.004" I'm not even trying to improve on that
05:47 PM JT-Shop: crap I have to replace the caliper mount a threaded hole is stripped out
05:47 PM xxcoder: cant do a insert?
05:48 PM JT-Shop: it's pretty thin so I doubt it
05:48 PM JT-Shop: the mount is only $75 and a butt load of work to change it out lol
05:51 PM * JT-Shop calls it a day
06:00 PM xxcoder: true labor costs go up quite fast
06:01 PM rdtsc: found out the wheel bearings commonly go out on my car; of course first put on all new rotors and pads, THEN they decide to start going out. Will need to regrind four rotors.
06:02 PM xxcoder: it got angry that it didnt get replaced
06:03 PM rdtsc: guess so! sorry car, I didn't know
06:05 PM JT-Shop: I'll put the LR caliper on before ordering any parts just to make sure it's not stripped out too...
06:05 PM xxcoder: yeah work longer, order less
06:05 PM * rdtsc crosses fingers for JT
06:06 PM JT-Shop: I'm guessing I'll have to take the half shaft out to replace the caliper mount but have not looked close at it
06:06 PM rdtsc: could try chasing threads, dunno if that would help
06:06 PM JT-Shop: nope they are stripped out... probably need a new bolt too because they are fine thread
06:07 PM rdtsc: drill + tap + threaded insert?
06:07 PM JT-Shop: well only one is stripped out
06:08 PM JT-Shop: the mounting boss is pretty thin so I'd rather just replace the part
06:08 PM JT-Shop: https://www.zip-corvette.com/65-82-rear-caliper-mount-bracket.html?srsltid=AfmBOoqrnHoe6YkljSRjT0wlPrYCwLqkbipFi_jhzQL_1hkWn0tx2LSyTyM#258=965
06:08 PM JT-Shop: the upper left hole is stripped out
06:09 PM JT-Shop: if I try and put a helicoil in I'd have to take it out to do so might as well just change it out be done with it
06:10 PM JT-Shop: time to cook tacos
06:10 PM rdtsc: not a cheap part, but a repair + time doesn't seem worth it. The wheel bearings in my car are a convenient assembly, but due to corrosion are an absolute bear to get out... plus the one I'd previously done won't communicate with the tire pressure sensor - couldn't get it to connect, even after using a pro scanner.
06:12 PM rdtsc: dunno what's more challenging... classic cars or modern ones lol
06:31 PM acer is now known as _unreal_
06:32 PM _unreal_: so I've finished building one dust shoe for the big machine for fine dust jobs. now I'm working on building the big one for large scale tooling
06:43 PM _unreal_: I also need to get some MDF to build up the base and make a waste board setup.
06:44 PM _unreal_: I'm trying to decide what the best method of making a spacer board and waste board
06:45 PM _unreal_: The base of this cnc machine is a very re-enforced wood base. the Z has about 8" max working area between the BASE deck of this new cnc machine and the highest the spindle can clear. the Z it self has 6" of working plunge
06:46 PM _unreal_: any thoughts on a best method? I'll post a photo in a second just so you guys know what I'm working with.
06:49 PM _unreal_: https://photos.app.goo.gl/Y8geHfgffQAP6oZN8
06:50 PM _unreal_: ?
07:23 PM _unreal_: finally finished uploading
07:23 PM _unreal_: https://photos.app.goo.gl/ggAPhV6uwbvr4jLs8
07:23 PM _unreal_: have a look
07:24 PM _unreal_: hum
07:24 PM _unreal_: everyone must be asleep
10:03 PM lcnc-relay: <knoxmachining> I would just do MDF
10:25 PM lcnc-relay: <captainhindsight_.> holiday weekend
10:28 PM lcnc-relay: <captainhindsight_.> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/txzFhleLjhuDPTQkfcXgQgDK/IMG_20240829_042016.jpg
10:28 PM lcnc-relay: <captainhindsight_.> our idea of a large cnc is different
11:06 PM _unreal_: captainhindsight compaired to my other cnc machine this new one is HUGE
11:08 PM _unreal_: and new discovery I need to add cross rolling steel wire to the X. it seems to flex in the x axis plane rotating the z. not much but I can see the deflection.
