01:34 AM Deejay: moin
01:50 AM lcnc-relay: <vibram> hello
04:40 AM Tom_L: morning
05:12 AM -!- #linuxcnc mode set to +v by ChanServ
05:21 AM JT-Mobile: morning
07:12 AM lcnc-relay: <Travis Farmer> Morning
07:15 AM rdtsc-wk: Morning
07:16 AM -!- #linuxcnc mode set to +v by ChanServ
07:20 AM rdtsc-wk: JT, if their drives are old, constantly going out, and are going to be replaced, suggest doubling up on replacements (provided there are free PLC outputs.) Have 2 drives wired to 1 motor and pick which one is enabled from the PLC. That way, when a drive dies, PLC can select the other drive (while the first one is being repaired/replaced) - no down-time. Of course, if you want to tackle that PLC config :)
07:21 AM JT-Mobile: I'm just going to have one drive per variable speed motor but all the components will be in an air conditioned enclosure so no over heating
07:21 AM rdtsc-wk: smart, heat is the enemy of VFDs
07:22 AM JT-Mobile: yup, it will take a rather large ac to keep all the drives cool... did the heat load calc on all the component
07:22 AM rdtsc-wk: Siemens drives are especially sensitive to it
07:23 AM rdtsc-wk: they design them right on the thermal envelope
07:23 AM JT-Mobile: I'm using AD drives
07:39 AM lcnc-relay: <Travis Farmer> hmmm, neighbor is getting a tree cut down... hope they don't drop anything on my nearby shop...
07:40 AM rdtsc-wk: chance is low, tree guys usually know what they're doing
07:40 AM lcnc-relay: <Travis Farmer> i hope your right...
07:40 AM Tom_L: the skinniest and craziest looking one will be up in the tree too.... bet
07:41 AM lcnc-relay: <Travis Farmer> they are using a lift truck
07:41 AM Tom_L: i used to help a friend with that and guess who got to climb :)
07:42 AM rdtsc-wk: well see, they wouldn't be able to afford the truck if they were careless :)
07:42 AM Tom_L: they didn't use those trucks back in the day. just rigging
07:42 AM Tom_L: anybody can rent a lift truck
07:42 AM lcnc-relay: <Travis Farmer> true, rdtsc
07:43 AM rdtsc-wk: assuming they have a company truck
07:43 AM lcnc-relay: <Travis Farmer> this is a company truck
07:43 AM Tom_L: yeah if you can paint yoru name on it, that's different
07:44 AM rdtsc-wk: about to power up a 150HP GE drive after some major repairs... lets hope for no surprises
07:44 AM * Tom_L backs up a bit
07:45 AM lcnc-relay: <Travis Farmer> BZZZZZAAAPPPP!
07:45 AM rdtsc-wk: if there's a surprise at this scale, it's more like a BOOOOOM
07:45 AM lcnc-relay: <Travis Farmer> well, take a video then
07:47 AM Tom_L: https://www.youtube.com/results?search_query=closing+a+transformer+breaker
07:47 AM Tom_L: https://www.youtube.com/watch?v=QC-OUnlpJ4k
07:47 AM Tom_L: rather that one instead
07:49 AM lcnc-relay: <Travis Farmer> a little anti climactic, Tom_L 😉
07:49 AM Tom_L: more a personal favorite https://www.youtube.com/watch?v=2NKOlLDNknc
07:51 AM lcnc-relay: <Travis Farmer> nice, a little bit of a load on the lines that day...
07:51 AM * Tom_L goes out to test
08:36 AM rdtsc-wk: https://www.youtube.com/watch?v=IobuasZqH38
08:39 AM lcnc-relay: <Travis Farmer> no offense, i really hoped for a boom 😉 congrats on a successful test!
08:40 AM rdtsc-wk: Well that's just powering it up, still have to run-test it. :)
08:41 AM lcnc-relay: <skunkworks8841> Dad bought a bad plasma I need to look at.. (decide if I want to fix it or scrap it)
08:42 AM -!- #linuxcnc mode set to +v by ChanServ
08:54 AM rdtsc-wk: never been shocked welding, but did get a nasty shock from a plasma cutter once when the concrete was wet
08:54 AM Tom_dev: JT-Mobile, where is the list of checkboxes for the plotter?
08:54 AM Tom_dev: this isn't showing a program using them from the menu
08:54 AM Tom_dev: with no checkboxes
08:54 AM lcnc-relay: <Travis Farmer> https://www.gnipsel.com/linuxcnc/flexgui/plotter.html#display
09:00 AM JT-Mobile: I just created a config with a plot and menu only view items and they all seem to work for me
09:01 AM Tom_dev: i'll go back inside and try to figure it out
09:01 AM Tom_dev: wanted to test these subs
09:03 AM JT-Mobile: https://pasteboard.co/zIaJB37Es73Q.png
09:04 AM Tom_dev: wrong tool table
09:04 AM Tom_dev: the one i copied was Tool.tbl and i needed tool.tbl ;)
09:05 AM Tom_dev: go back to fishin, pole in one hand, beer in the other :)
09:05 AM lcnc-relay: <Travis Farmer> LMAO
09:07 AM rdtsc-wk: Tom and the Two Terrible Tool Tables
09:08 AM lcnc-relay: <Travis Farmer> lol
10:31 AM Tom_L: helps if you get the test angle the same as the cad file
10:31 AM Tom_L: is it Monday?
10:40 AM lcnc-relay: <Travis Farmer> actually, i think it is Thursday... 😉
11:11 AM * Tom_L decides it's 'one of those days' and stops for a while
11:11 AM lcnc-relay: <Travis Farmer> having troubles?
11:14 AM Tom_L: nothing i can't figure out but i need a break
11:15 AM Tom_L: the angles report the correct angle, now working on model orientation
11:38 AM Tom_L: JT-Mobile, around?
11:44 AM rdtsc-wk: It's Monday #4
11:48 AM Tom_L: rdtsc-wk,
11:48 AM Tom_L: explain this one
11:49 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/angle_rotation/15Deg_Square.jpg
11:49 AM Tom_L: angle says 15 degrees mkay?
11:49 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/angle_rotation/15Deg_Square_rotate15.jpg
11:49 AM Tom_L: rotation angle says 15 deg mkay?
11:49 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/angle_rotation/15Deg_Square_rotate30.jpg
11:49 AM Tom_L: takes 30 deg to square it up with the axis
11:50 AM Tom_L: explain?
11:50 AM Tom_L: only thing i can come up with so far is per quadrant which doesn't make sense
11:51 AM Tom_L: or JT-Mobile for that matter
11:52 AM Tom_L: ran a few tests with a block bolted down at 15 degrees for probing and another block beside it sitting square to the axis
11:53 AM Tom_L: i verified the 15 degrees manually and with the probe
11:53 AM Tom_L: those agree
11:53 AM Tom_L: but i couldn't figure out why the model wasn't fully rotated when i ran it above the squared up block
11:55 AM Tom_L: my mill findings follow what the cad model is doing on a rotate though
11:59 AM Tom_L: i somewhat measured the model on the screen in linuxcnc too and before rotation it's closer to 30 deg than 15 for sure
12:05 PM rdtsc-wk: https://youtu.be/CzttK2tcrrk
12:05 PM rdtsc-wk: https://youtu.be/6wyyUB8-DXs
12:05 PM rdtsc-wk: https://youtu.be/TfjPuwYkeR0
12:07 PM Tom_L: :)
12:11 PM Tom_L: ok i think cnc is correct and my cad model needs an adjustment
12:11 PM Tom_L: certainly strange behavior
12:13 PM lcnc-relay: <Travis Farmer> rdtsc: "rut row" 🤣
12:15 PM lcnc-relay: <Travis Farmer> and now you have a subscriber 😉 🙂
12:32 PM lcnc-relay: <Travis Farmer> <-- heads out to shop to test a few things...
12:34 PM lcnc-relay: <oz7137> hey there,
12:34 PM lcnc-relay: i'm trying to start my first linuxcnc setup, but i'm missing something...
12:34 PM lcnc-relay: HAL: ERROR: function 'not.1' not found
12:34 PM lcnc-relay: <oz7137> and in the config i have:
12:34 PM lcnc-relay: addf not.1 servo-thread
12:35 PM lcnc-relay: <oz7137> (it's already working for first axis, this happens when I add a second axis)
12:37 PM Tom_L: did you tell it you had 2 now instead of just one?
12:37 PM Tom_L: loadrt
12:38 PM rdtsc-wk: Travis, I'd intended to make an electronics YT channel... dunno if it will ever happen though
12:39 PM Tom_L: oz7137, loadrt not count=2
12:39 PM Tom_L: then you have not.0 and not.1
12:40 PM lcnc-relay: <oz7137> that's it, thanks
12:41 PM lcnc-relay: <oz7137> ok, now is the time I either nailed it, or crash the axis XD
12:42 PM rdtsc-wk: use a very slow speed limit to prevent crashes :)
12:44 PM lcnc-relay: <oz7137> yeah, dont worry no machine will be harmed ~today~ ~now~ at the moment 😉
12:50 PM lcnc-relay: <skunkworks8841> rdtsc-wk: a high power electronics channel - I bet it would do well
12:51 PM lcnc-relay: <skunkworks8841> expecially if there is a bang every so often..
12:51 PM lcnc-relay: <skunkworks8841> 😉
12:51 PM rdtsc-wk: Travis, so much work was done to that drive, incredible. Had to weld on a new aluminum bus bar stub and drill it for the bolt. Bus bar separator plastic was melted, fabbed new. U channel all blown up, replaced 8 components on the main board, list goes on and on
12:51 PM rdtsc-wk: just relieved it's running and heading back to the customer :)
12:53 PM rdtsc-wk: I'm surprised nobody has commented about my chicken-stick lol (I've had 'em blow up in my face - no thanks)
06:35 PM -!- #linuxcnc mode set to +v by ChanServ
07:40 PM rdtsc: Unterhausen, might be time to "roll" your own... https://www.ebay.com/sch/i.html?_nkw=direct%20bury%20fiber
07:41 PM rdtsc: kidding of course (doubt the city would like their streets tore up for one fiber cable heheh)
07:43 PM JT-Mobile: we have fiber that runs down every main road but it's not connected to anything
07:44 PM rdtsc: our ISPs have been promising fiber here for years... still vaporware
07:44 PM JT-Mobile: I'm struggling to find a hal pin that's not available in linuxcnc.stat()
07:45 PM JT-Mobile: and can't figure out why I would need to have hal readers in flex
07:47 PM JT-Mobile: http://linuxcnc.org/docs/stable/html/config/python-interface.html#_linuxcnc_stat_attributes
07:53 PM JT-Mobile: no clue what gstat is for it seems to just be a duplicate of stat
07:53 PM JT-Mobile: http://linuxcnc.org/docs/2.8/html/gui/GStat.html#_sample_gstat_code
07:54 PM JT-Mobile: but seems to also be unfinished
08:19 PM * JT-Mobile calls it a night
08:20 PM Tom_L: all the inch angle routines have been tested on metal
08:21 PM Tom_L: all the metric ones have been updated but not tested
08:24 PM Tom_L: Gstat() https://linuxcnc.org/docs/devel/html/gui/gstat.html
08:25 PM rdtsc: these are all good questions for seb if he's around :)
08:25 PM Tom_L: next to never in here
08:25 PM Tom_L: once in a while in devel
08:26 PM Tom_L: although he's here
09:14 PM rdtsc is now known as rdtsc_away
09:17 PM Unterhausen: the electric company did part of the rewiring of our street with directional drilling
09:18 PM Unterhausen: they put a trench through our driveway though
09:20 PM Tom_L: how kind
09:35 PM roycroft: possibly there were other utilities under the driveway
09:36 PM roycroft: directional drilling is great, but just as a backhoe is magnetically attracted to underground fiber, directional drills are magnetically attracted to water, sewer, and gas pipes and electrical and communications conduits/cables

09:36 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/touch-probe2-testset2.png
09:36 PM Tom_L: 2 test programs one a mirror of the other
09:37 PM Tom_L: for the 2 angle probe sets
09:38 PM Tom_L: all 8 tested on metal
09:39 PM Tom_L: i will tell you, you'd better issue a G10 L2 P0 R0 because the angle offset is persistent
09:39 PM Tom_L: to zero the axis again
09:40 PM Tom_L: i could make a button for that but that would be too fckn easy
09:41 PM Tom_L: roycroft, isn't that why you call 811?
09:56 PM roycroft: yes, but when the utilities are really close together it's hard to weave the drill in between them
09:57 PM roycroft: i've managed a number of jobs where we had to do some trenching at greater expense than drilling because of the difficulty in avoiding other utilities
10:46 PM lcnc-relay: <big_kevin420> the most linuxcnc statement ever
10:46 PM lcnc-relay: <big_kevin420> "i could make a button for that but that would be too fckn easy"
