01:27 AM Deejay: moin
04:36 AM Tom_L: morning
04:36 AM Tom_L: robotustra, yes you still need preempt-rt
04:36 AM Tom_L: even more so with a parport
05:26 AM JT-Cave: morning
06:04 AM JT-Cave: yuck still raining
06:14 AM JT-Cave: rooster just crowed
06:20 AM Tom_L: JT-Cave, you see the issue i posted?
06:56 AM JT-Cave: yup
07:04 AM JT-Cave: now where did I put the wago connector
07:05 AM JT-Cave: and my flashlight
07:06 AM Tom_L: i've noticed i spend more time looking for things nowdays
07:07 AM Tom_L: 65°F
07:07 AM Scopeuk: Is that your memory or that you have more stuff? Pretty easy to find your 1 set of pliers, trickier to find your soft jaw parallel jaw pliars last used 5 years ago
07:07 AM Tom_L: rained earlier
07:08 AM Tom_L: some of both
07:08 AM Tom_L: mostly the former
07:26 AM JT-Cave: found the flashlight... wife woke up so I could turn the light on in the bedroom and find the wago connector
07:29 AM travis_farmer: you keep your wago connectors in the bedroom? kinky...
07:30 AM JT-Cave: it was in my shirt pocket...
07:31 AM travis_farmer: sure it was... ;-)
07:46 AM JT-Cave: Tom_L, I just tested a single estop input and it works fine
07:55 AM JT-Cave: I think I'll add some more switches to my project box to test multiple estop code
09:29 AM roycroft: residents near one of our new fires were just issued a level 3 "go now!" evacuation notice
09:29 AM roycroft: and that fire is very near a large area that burned about 3 years ago
10:15 AM JT-Shop: seriousxm is really trying to get me to use them again on the Honda's

11:21 AM CaptHindsight: "gamepad" controlled almost CNC aluminum lathe https://www.kickstarter.com/projects/rowndprecision/rownd-cnc-lathe-machining-for-everybody?ref=aoglio
11:30 AM Tom_L: JT-Shop, i tried my estop again and it's working now. i have no idea why it wasn't before
11:31 AM JT-Shop: sun spots
11:31 AM Tom_L: had to be
11:32 AM Tom_L: the code looked virtually the same as what is on my mill other than the or2 component for 2 buttons instead of one
11:33 AM Tom_L: did you fix that other issue?
11:33 AM Tom_L: i'll build if you did here in a bit
11:34 AM Tom_L: so you use multiple estop-latch rather than an or statement?
11:34 AM CloudEvil: CaptHindsight: half the price of the haas desktop mill, though I haven't carefulkly looked at specs
11:36 AM Tom_L: i suppose it's easier to manage the code in mesact that way
11:38 AM Tom_L: or2 or logic9 for multiple estop inputs would also work
11:38 AM Tom_L: little harder to set up a logic9
11:41 AM JT-Shop: other issue?
11:41 AM Tom_L: the servo_thread
11:41 AM JT-Shop: yes multiple estop-latch
11:41 AM Tom_L: or whatever it was called...
11:42 AM JT-Shop: https://github.com/jethornton/mesact/commit/257bfe3d586a918f2ae27c11b5a9afeb0dafac12
11:42 AM Tom_L: ok
11:43 AM JT-Shop: after the nap I'll wire up a few switches and test multiple estops
11:43 AM Tom_L: i'll build after lunch
11:43 AM JT-Shop: nap? hmm that's a good idea as it's raining a tad
11:44 AM Tom_L: i'll try one NC and one NO and see also
11:44 AM Tom_L: mine is actually like that
11:44 AM Tom_L: i think the NO is on the pendant
11:47 AM Tom_L: servo thread looks ok now
11:55 AM CloudEvil: CaptHindsight: The price looks reasonable for the capacity, buut.
11:55 AM Tom_L: JT-Shop, 2 estop, one NC one NO works
11:57 AM Scopeuk: is that not a fairly normal setup for parity, one common and then connect both no and nc so you can check for 1 high only to confirm you have a valid end stop signal
11:58 AM Tom_L: you typically want NC but that's the switches i had
11:58 AM Tom_L: but it should be tested for both anyway
12:01 PM Deejay: re
12:04 PM Tom_L: JT-Shop, PR #13
12:05 PM Tom_L: now lunch then nap
12:44 PM JT-Shop: limit switches in a machine should always be n/c, using n/o switches is dangerous
01:01 PM CaptHindsight: https://linuxgizmos.com/orange-pi-teases-sbc-based-on-rockchip-rk3566/ another Rpi replacement
01:01 PM CaptHindsight: $34.99 - $67.99

03:31 PM Tom_L: JT-Shop, do you know if the 7i96s spindle interface can tolerate 12v?
03:32 PM Tom_L: i _think_ it's just a 10v swing
03:32 PM JT-Shop: The voltage supplied between SPINDLE+ and SPINDLE- must be
03:32 PM JT-Shop: between 5VDC an 18VDC with SPINDLE + always being more positive than SPINDLE-.
03:32 PM Tom_L: i'm reading that atm
03:33 PM Tom_L: i was gonna test the spindle but only have 12v easily available
03:33 PM JT-Shop: 12v works if your just using a volt meter to test with
03:34 PM Tom_L: i didn't wanna blow the chip was all
03:34 PM Tom_L: have you tried it?
03:34 PM JT-Shop: yup I used 10v because it's easier to do the math
03:35 PM JT-Shop: but I can raise the voltage up with my rat shack power supply
03:36 PM Tom_L: you must still be working on 7i92T stuff
03:36 PM Tom_L: i see all the greyed boxes
03:39 PM JT-Shop: still polishing up the 7i96s but I assume your looking at spindle type combo box
03:40 PM Tom_L: no i was just going to wire one and measure the voltage out
03:40 PM Tom_L: but you did that
03:44 PM Tom_L: JT-Shop, http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/mesact2/mesact2_error1.png
03:45 PM Tom_L: opened a 2.0.0 ini, it made a backup then i saved the config to update the version
03:46 PM JT-Cave: can you post the ini
03:46 PM Tom_L: i'm double checking to be sure
03:46 PM Tom_L: then i will
03:47 PM JT-Cave: hmm buildss.py, I've not looked at it much yet
03:48 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/mesact2/mesact2_7i96s_test.ini
03:48 PM Tom_L: that's the ini before conversion
03:49 PM Tom_L: needs an ip selected
03:49 PM Tom_L: forgot that on that one
03:50 PM Tom_L: but it does build some files. whether they're ok i dunno
03:53 PM Tom_L: oh. that error is on the sserial card
03:54 PM Tom_L: it seems to build the other files but not the sserial.hal
03:55 PM JT-Shop: looks like that option is missing from the dictionary used to build the ss.py file
03:56 PM Tom_L: i couldn't find those io at first then looked in the ss card tab
03:56 PM Tom_L: it loads them in from the 2.0.0 file but doesn't save them
04:02 PM JT-Shop: I need to just use one dictionary for inputs and outputs looks like ss.py is missing all the Joint n Plus and Home key/values
04:03 PM Tom_L: ahh i see that now
05:44 PM CaptHindsight: https://youtu.be/CCGTdPGbXME?t=143 polyurea coatings
05:46 PM Tom_L: tough stuff
06:51 PM -!- #linuxcnc mode set to +v by ChanServ
06:51 PM Tom_L: JT-Shop, posted a checkbox issue
07:48 PM JT-Cave: ok
07:49 PM Tom_L: i thought at first the copy values in the joint section wasn't working on all tabs but not sure
07:49 PM Tom_L: i closed that issue for now
07:49 PM Tom_L: i'm re'checking that
07:50 PM Tom_L: yes, that works fine i just forgot how to use it :)
07:50 PM Tom_L: JT-Cave, i just built a complete 4 axis config and ran lcnc and it works. except i didn't add sserial
07:52 PM JT-Cave: cool
07:53 PM Tom_L: i also added a sserial just now and it output a sserial.hal
07:53 PM Tom_L: didn't select those io though so some of it works
07:54 PM Tom_L: the joint + home is the culprit
09:24 PM * roycroft is sitting in a campground enjoying the 19 degree temperature, knowing eugene got up to 42 today
09:24 PM roycroft: there was smoke from the new fire this morning, which kept the temperature down, but the sun started coming through the smoke by the time i left
