05:31 AM Deejay: hi
05:38 AM JT-Mobile: morning
06:05 AM Tom_L: morning
07:14 AM Gothia1 is now known as Gothia
10:04 AM t4nk_fn: :| I've been hammering away some more, can't get the darned shaft out
10:04 AM t4nk_fn: aint got no tools either, not even something to clamp it down properly
10:10 AM lcnc-relay: <lesliet@> _shivers_
10:11 AM lcnc-relay: <lesliet@> hate being in the place of not having tools and a workshop, hopefully never again in this lifetime
10:12 AM lcnc-relay: <lesliet@> any chance that thing is spot welded in there, or otherwise permanently affixed?
10:12 AM lcnc-relay: <lesliet@> a lot of the cheap chairs are really not made to be fixed, so it can be a challenge
10:12 AM lcnc-relay: <lesliet@> even a lot of the better quality ones
10:27 AM t4nk_fn: https://postimg.cc/XrwFMjPb
10:27 AM t4nk_fn: pff
10:29 AM t4nk_fn: I drilled a hole at the bottom there, and stuck a screwdriver through optimistically thinking that would work
10:30 AM t4nk_fn: now all I had left was to use a wrench, and slide it up against the bigger shaft.. and then hammering the wrench as best as possible from underneath
10:31 AM t4nk_fn: somehow I don't think this'll end until I pull a Tyson Fury and uppercut myself with a hammer
10:34 AM t4nk_fn: doesn't help that the thing has been sat on for years and years
10:42 AM lcnc-relay: <lesliet@> could there be a circlip on the other side holding it in?
10:45 AM t4nk_fn: that would be really messed up.. guess it could be possible
10:46 AM Tom_L: round 2 ehh
10:46 AM t4nk_fn: but I don't think so.. these things are probably all just held by pressure, since it can't go anywhere but tighter
11:16 AM andypugh_ is now known as andypugh
11:16 AM lcnc-relay_ is now known as lcnc-relay
12:50 PM t4nk_fn: I am completely enraged.
12:50 PM t4nk_fn: and this is not over.
12:52 PM t4nk_fn: but for now I'll just put the new chair together.. *sigh*
12:52 PM t4nk_fn: gives me time to figure out how to clean the fabric
12:53 PM lcnc-relay: <lesliet@> can't be tight if it's a liquid
12:54 PM t4nk_fn: give me a long enough lever.. and I'll move that shaft
12:55 PM lcnc-relay: <lesliet@> (disclaimer: don't use a cutting torch on a gas cylinder, it will either explode, or when it ruptures, you get jets of burning oil shooting out at you)
12:56 PM t4nk_fn: lol.. trust me.. this one will do nothing of the kind!
12:56 PM lcnc-relay: <lesliet@> already cracked open?
12:56 PM t4nk_fn: otherwise it would have stayed upright ;)
12:57 PM xxcoder: if I recall right, you could drill a hole and fill tank completely with water to ensure it has no gas left, but could be wrong.
12:57 PM t4nk_fn: I drilled some holes through it ;)
12:57 PM lcnc-relay: <lesliet@> xxcoder: this is true. I've done it, on a gasoline tank, but it's still a bit scary
12:57 PM lcnc-relay: <lesliet@> co2 purge also works
12:57 PM lcnc-relay: <lesliet@> or argon
12:58 PM lcnc-relay: <lesliet@> I was more thinking of the shock absorber style things in chairs, some of them may have oil inside for dampening motion
12:59 PM xxcoder: ahh ok
01:13 PM Tom_L: t4nk_fn, this is starting to become comical

02:33 PM lcnc-relay: <lucid.nonsense@> I feel like I'm having a blow by blow rendition of Daffy Ducks thought process and it's fabulous, wish you'd recorded it

02:40 PM JT-Mobile: raining now
02:50 PM Tom_L: we got that overnite
02:53 PM JT-Mobile: looks like it will move out before dinner time
02:54 PM JT-Mobile: best time today was 1:14
02:54 PM Tom_L: is that good?
02:55 PM JT-Mobile: very
02:55 PM Tom_L: at least you got some laps in before rain
02:55 PM Tom_L: so you must like the new tires
02:55 PM JT-Mobile: I was really surprised that they put me in group 1
02:55 PM JT-Mobile: yup
02:57 PM JT-Mobile: had a guy in a Porsche complement me on my driving skills... he never could catch me
02:57 PM Tom_L: dealing with ins and contractors a bit today
02:57 PM JT-Mobile: fun
02:57 PM Tom_L: did you bruse his ego?
02:58 PM JT-Mobile: no, he was studying my line that I drove
02:58 PM JT-Mobile: no ego's out there
02:58 PM Tom_L: that's good
02:59 PM JT-Mobile: I'm pretty familiar with track and what line to take for the fastest lap time
02:59 PM JT-Mobile: there was 6 cars from Poplar Bluff 5 Corvettes and a Mustang GT Shelby
03:00 PM Tom_L: you know any of em?
03:01 PM JT-Mobile: yup, one new one I met today but the rest I've known for a while
03:01 PM Tom_L: makes it more fun
03:03 PM JT-Mobile: yup
03:04 PM JT-Mobile: I was looking at the map this morning and it looked like Bowling Green was a good place to spend the night when going to the sibling rendezvous in October
03:04 PM JT-Mobile: turns out the Corvette plant has plant tours for one week this month and one week next month
03:05 PM JT-Mobile: I managed to book a tour the day we arrive there
03:18 PM Tom_L: that's cool
03:21 PM JT-Mobile: there's been no plant tours in a couple of years and they only had 10 days of tours
03:54 PM lcnc-relay: <lesliet@> perfect timing
04:00 PM JT-Mobile: lucky I'd say
04:16 PM * JT-Mobile tries to decide if a nap is in order
05:30 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/axis_probe_test2.png
05:30 PM Tom_L: axis probe routines work like a champ
05:35 PM lcnc-relay: <skunkworks8841@> cool@
05:35 PM lcnc-relay: <skunkworks8841@> tried it on machine?
05:37 PM lcnc-relay: <skunkworks8841@> hmm - wonder where the 5hp briggs that dad bought new in the early 80's is.. It is white if anyone finds it
05:37 PM lcnc-relay: <skunkworks8841@> (been used for so many things - last was a hydraulic power pack that has been converted to electric)
05:41 PM Tom_L: yes, machine tested
05:41 PM Tom_L: reads the spinbox from the analog in
05:41 PM Tom_L: other parameters are preset
05:42 PM lcnc-relay: <skunkworks8841@> nice
05:43 PM Tom_L: handy for setting the vise or work plate
05:43 PM lcnc-relay: <skunkworks8841@> probing is handy in general
05:43 PM lcnc-relay: <skunkworks8841@> I can't imagine a cnc without one
05:43 PM Tom_L: quicker than a wobbler
05:43 PM lcnc-relay: <skunkworks8841@> yes
05:43 PM lcnc-relay: <skunkworks8841@> I have never used a wobbler
05:43 PM lcnc-relay: <skunkworks8841@> Don't want to
05:43 PM Tom_L: i did for quite a while
05:44 PM xxcoder: I never used one
05:44 PM lcnc-relay: <skunkworks8841@> they now have dro's that take probe inputs.. Seems likes the way to go
05:44 PM xxcoder: looks awkward
05:44 PM lcnc-relay: <skunkworks8841@> if that is all you have - they seem great.
05:45 PM lcnc-relay: <skunkworks8841@> I have never had anything with a dro on it.
05:45 PM Tom_L: one i got from my kid has a flat on it so you can hear it
05:45 PM lcnc-relay: <skunkworks8841@> by design? that helps?
05:46 PM Tom_L: yes, it clicks
05:46 PM lcnc-relay: <skunkworks8841@> ah - neat
05:53 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/cutters/Edgefinder.jpg
05:54 PM Tom_L: couldn't find it.... was looking for 'wobbler'
05:54 PM xxcoder: nice. heard of that, but noise would have been useless for me
05:54 PM Tom_L: yeah
05:54 PM xxcoder: I only have plain edgefinder lol
05:55 PM lcnc-relay: <skunkworks8841@> it is kinda funny.. we never had a edgfinder here - Like I have never run across one either.
05:56 PM lcnc-relay: <skunkworks8841@> dad used one when he was working in the machine shop at my work - just as part time help..
05:56 PM lcnc-relay: <skunkworks8841@> when he was retired
05:56 PM lcnc-relay: <skunkworks8841@> but - they figured out he did faster work in his own shop.. so they gave him a bunch of work to do. worked out well
06:10 PM Tom_L: after my friend sold his shop, he still did/does work for them that they don't wanna do or can't figure out how
06:28 PM JT-Mobile: going to be an early night for me
06:31 PM Tom_L: JT-Mobile, check the dev channel
06:33 PM Tom_L: JT-Mobile, http://tom-itx.no-ip.biz:443/~tom-itx/irc/logs/%23linuxcnc-devel/2025-09-20.html
06:33 PM JT-Mobile: j,mm
06:33 PM JT-Mobile: hmm
06:35 PM -!- #linuxcnc mode set to +v by ChanServ
06:36 PM Gothia1 is now known as Gothia
07:47 PM rdtsc: I bet you could feel the clicking in the machine, xxcoder
07:47 PM xxcoder: I suppose but meh I can just use eyes
07:48 PM rdtsc: rely on a "wobbler" here, weird device but fast and easy to use
07:53 PM lcnc-relay: <skunkworks8841@> I think you are evil for saying that. i have never used one - and I don't like them..
07:55 PM lcnc-relay: <skunkworks8841@> finally got off all the crap off the top of the parts cleaner.. Now I can clean a carberator...
07:55 PM lcnc-relay: <skunkworks8841@> I am having flash backs. I have cleaned so many of these briggs carbs.. We built so many engines from junk yard parts.. I think I could do it blind folded..
07:56 PM lcnc-relay: <skunkworks8841@> 2hp, 5hp briggs.. The ones that had syncro balance.. they had an extra weight that went the oposite direction of the piston..
07:57 PM lcnc-relay: <skunkworks8841@> only single cylinders.. i was pretty old when we got a mower that had a 2 cylinder briggs.. Neve had one apart...
07:57 PM lcnc-relay: <skunkworks8841@> never
07:59 PM lcnc-relay: <skunkworks8841@> We had a few onnan 2 cylinders.. One on a 7ish KW generator and dad found 2 identical ones in the junk yard. one is still in the polebuilding.. one was on a forklift that dad converted to hydraulic.. (was electric - probably from the 70's)
07:59 PM lcnc-relay: <skunkworks8841@> I think it is still around (the engine) it is just halfway into the dirt...
08:00 PM lcnc-relay: <skunkworks8841@> weight.. wow - I suck at spelling
08:45 PM lcnc-relay: <lesliet@> so, doing my obsessive digging into ac servos and other alternatives to power my machine, and I realized that I crunched some numbers wrong, and the originals were 3.4 nm
08:46 PM lcnc-relay: <lesliet@> found some rather nice 3.18nm ac servos that use ethercat, and I wanted to ask if ethercat is a good thing with linuxCNC?
08:47 PM lcnc-relay: <lesliet@> looks like I'll have to turn some shaft adaptors up, whatever I do. 5/8" shaft servos are not exactly thick on the ground, unless you want to pay a grand each
08:48 PM lcnc-relay: <lesliet@> most of what I'm seeing uses 19mm keyed shafts
08:48 PM Tom_L: ethercat is a fairly new thing for linuxcnc but some are using it
08:49 PM lcnc-relay: <lesliet@> hmm, wonder if it suffers from not being well matured in linuxCNC?
08:49 PM Tom_L: most are used to using steppers or servos
08:49 PM Tom_L: with the conventional interfaces
08:50 PM lcnc-relay: <lesliet@> ok, good to know
08:50 PM Tom_L: you may end up looking to the forum for help for that
08:50 PM Tom_L: there may be a couple here using it
08:51 PM Tom_L: i don't use it so i haven't followed it's progression that closely
08:52 PM lcnc-relay: <lesliet@> they have a pulse option, so I'll probably go that route
08:52 PM lcnc-relay: <lesliet@> still have a fair bit of figuring out to do before I start spending money
08:54 PM Tom_L: https://forum.linuxcnc.org/ethercat/22346-ethercat-hal-driver
08:55 PM Tom_L: https://forum.linuxcnc.org/ethercat/51187-new-linuxcnc-ethercat-git-tree
08:57 PM lcnc-relay: <lesliet@> danke
09:02 PM lcnc-relay: <lesliet@> think I have a winner, for now. $206 per axis, 1kw 3.18nm/11nm peak, 3000rpm/6000 rpm peak includes servo and driver. Does pulse, rs485, and analog
09:02 PM lcnc-relay: <lesliet@> and looks like the instructions are in pretty good english
09:04 PM lcnc-relay: <lesliet@> motors are only 107mm long, vs the original 300mm ones, so plenty of room for adaptors
10:52 PM fywolfluff is now known as fluffywolf
