01:01 AM Deejay: moin
01:34 AM Loetmichel: mornin'. *meh* you drive to work ONCE with the ragtop open and the hair looks like the hairdryer exploded in the morning :-(
03:07 AM Loetmichel: hehe, coworker is a weakling... just cut a 50mm square steel tube with 2mm wall thickness on the wood table saw... coworker: "Careful, you are throwing sparks all over the workshop, dont put anything aflame!!!!" ;)
04:48 AM JT-Cave: morning
06:11 AM Tom_L: morning
06:12 AM Tom_L: 47F currently
07:06 AM Loetmichel: *hrrrmph* what a mess.. proxxon IBS/e died with burnt windings... orederd a new motor... just checking Three of the four 1n4007 rectifier diodes shorted... and such a simple part is nowhere to be found in this company... complex processors, simple resistors in 0805... not a slinge diode that still has leads :-(
08:36 AM roycroft: things are looking a bit better today
08:36 AM roycroft: no more evacuation orders in my area overnight, the wind has subsided a bit, and it's a little less smoky
08:37 AM roycroft: the wind shift from the south is now forecast for about 3am tomorrow, more than a day sooner than the forecast as of late last night
08:39 AM JavaBean: my area is surprised by a cold front that came in overnight... high today is supposed to be arround 30f cooler than it was yesterday
08:45 AM roycroft: that sounds like colorado
08:46 AM JavaBean: nah, far west texas
08:48 AM robotustra: boka chika?
08:48 AM robotustra: do you see rocket launches?
09:04 AM * JT-Shop is not going to be worth a shit today... just put Pig Pen down :(
09:23 AM rs[m]: JT-Shop: your clock tower?
09:31 AM JT-Shop: a 3 year old hen that got flystrike
09:36 AM rs[m]: sorry to hear that
09:44 AM JT-Shop: yeah I wish I had caught it earlier...
09:50 AM robotustra: where is the fire?
09:53 AM roycroft: northeast of here, about 65km away
09:54 AM roycroft: it's currently 32,000 acres (13,000 hectares), 0% contained
09:54 AM roycroft: the current estimate is that it will be contained on 29 october
10:16 AM Rab: roycroft, glad to hear things are looking better.
10:16 AM roycroft: yeah, it's quite a relief
10:17 AM roycroft: things never got too dire right here, but last night they were esclating rapidly
10:17 AM roycroft: and i wasn't sure what was going to happen
11:21 AM XXCoder: JT-Shop: man i got scared today lol. i called my old job see whats going on, and number was dead
11:21 AM XXCoder: so I went in person to find out whats going on. thankfully it was att service problem
12:38 PM unreal is now known as Guest71109
12:49 PM roycroft: ok, that was the last straw
12:49 PM roycroft: i just got car extended warranty scam calls on both my land ine and cell phone at exactly the same time
12:49 PM roycroft: they literally both started ringing at the same time
12:49 PM roycroft: and "amy" was on both lines at the same time
12:53 PM Tom_itx: roycroft, what kind of car do you not own?
12:53 PM Tom_itx is now known as Tom_L
01:58 PM JT-Shop: hmm I think there is a way to read a hal pin in g code but I'm brain dead today after killing one of my hens... anyone know how?
02:01 PM JT-Shop: found it
02:10 PM robotustra: and how?
02:10 PM robotustra: you mean to read it to the parameter?
02:11 PM robotustra: like #x=...?
02:12 PM JT-Shop: it's #<_hal[pin-name]> in g code
02:12 PM JT-Shop: in 2.8 >
02:12 PM robotustra: is it a rs274 standard or linuxcnc specific?
02:13 PM JT-Shop: no clue, never studied rs274
02:14 PM rs[m]: JT-Shop: M66
02:15 PM rs[m]: http://linuxcnc.org/docs/html/gcode/m-code.html#mcode:m66
02:15 PM rs[m]: the pin has to be connected to motion.digital-in-XY
02:16 PM rs[m]: how many digital/analog inputs/outputs are available can be configured at motion load time IIRC
02:30 PM JT-Shop: rs[m], I'm reading the state of a button on my QtPyVCP GUI so long as it checked continue with the endless loop probing the part when I uncheck it the probing and logging stops
02:32 PM roycroft: and the evacuation notices are coming over the radio every few minutes again
02:33 PM roycroft: so i guess things are not doing well
02:33 PM roycroft: actually, it makes sense, since the wind shifted direction early this morning and died out, but is picking up again
02:34 PM roycroft: it's still northerly, so the air should actually clear up here a bit more as the day progresses
02:35 PM roycroft: holy moly
02:35 PM roycroft: the holiday fire - that's what they've finally named the conflagration - has grown from 32,000 acres to 105,000 acres since last night
02:36 PM pcw_home: It was really weird in the Bay Area this morning at 9 AM it was as dark as 9 PM with a dull red sky
02:37 PM pcw_home: air is ok since we have a cool sea breeze, but ominous sky
02:39 PM roycroft: that's how it was here yesterday
02:39 PM roycroft: the sky is a kind of light peach color today
02:39 PM roycroft: and there's a big, dark red orb in the sky
02:39 PM roycroft: kind of
02:39 PM roycroft: there's a semblence of a big, dark red orb in the sky, but it can't really be seen clearly
02:43 PM roycroft: all national and state parks in western oregon are closed, both for day use and camping, and all blm campgrounds are closed
02:43 PM roycroft: our county parks just closed
02:50 PM pcw_home: Sky is peach colored here now, I suspect the darkness was a combination of overcast here + sunlight filtered through many miles of smoke
02:52 PM pcw_home: I cant imagine why the park where the "gender discovery" party started that fire was open
02:53 PM robotustra: roycroft, I told you, fireproof your new bench!
02:54 PM Tom_L: pcw_home, any new mesa cards in the works?
02:55 PM pcw_home: 1 plasma specialized card
02:56 PM pcw_home: but we are working only 1/2 time so pretty slow on new stuff (plus I'm getting old and slow...)
03:02 PM Tom_L: we all are :)
03:04 PM serp: plasma specialized card you say? :)
03:05 PM pcw_home: Built in THC A-D and Ohmic sensor
03:07 PM JT-Cave: cool
03:08 PM R2E4: Anyone seen JT around?
03:08 PM pcw_home: He's in his cave
03:08 PM R2E4: Does he have a doorbell on his cave?
03:09 PM JT-Cave: yo
03:10 PM serp: pcw_home: sounds great.. i assume works well with plasmac? :)
03:15 PM robotustra: pcw_home, are you mesa boards designer?
03:17 PM pcw_home: Yes
03:18 PM robotustra: nice to know, I didn't connect my mesa board yet
03:18 PM skunkworks: writting the 2.8 usb...
03:18 PM pcw_home: Plasma THC and Ohmic HAL connections will be different since A-D is different
03:19 PM skunkworks: pcw_home: separate boards? or are you going to have omic and voltage on the same card?
03:20 PM pcw_home: same card
03:20 PM skunkworks: cool!
03:21 PM pcw_home: Also delta-sigma A-D vs V-F so a bit higher resolution/speed
03:22 PM pcw_home: and AC Ohmic sensor to avoid electrolytic corrosion
03:22 PM skunkworks: pcw_home: always the good stuff...
03:26 PM Deejay: gn8
03:26 PM pcw_home: I still have to write the SINC3 filter for the A-D and its HM2 interface in the driver
03:34 PM R2E4: JT-Cave: Hey ypou have any standoffs for 7i92M in stock?
03:35 PM R2E4: din rail mopunts I mean
03:47 PM JT-Cave: never made any yet
03:48 PM JT-Cave: looks like 2.250" centers
03:49 PM R2E4: ok my giuy I told him to order the extra ones for the 7i76 and redrill and tap for the 7i92
03:49 PM R2E4: btw I sent someone your way....
03:50 PM JT-Cave: ah ok he emailed me I think
03:50 PM R2E4: HE just ordered.
03:51 PM R2E4: yeah, Travis
03:51 PM R2E4: I am going to help[ him remoptely wioth his AXYZ router.
03:51 PM JT-Cave: wonder why he ordered an IDC26F plug?
03:52 PM R2E4: for the 7i76 to 7i92M
03:52 PM R2E4: ojh shit, thats the wrong cable
03:52 PM JT-Cave: he just ordered a plug not a cable
03:52 PM JT-Cave: https://mesaus.com/product/db25m-db25f/
03:53 PM R2E4: DB25M-DB25F flat cable?
03:54 PM JT-Cave: for both close together
03:54 PM JT-Cave: yes
03:58 PM JT-Cave: does he have a way to drill and tap the 3.7 DIN rail mount?
03:59 PM * JT-Cave wanders up to the machine shop
04:01 PM skunkworks: the livecd booted!
04:02 PM skunkworks: seems to run about the same latency on the 8200
04:05 PM JT-Shop: anyone read a hal pin in g code? I'm not getting it to work following the docs http://linuxcnc.org/docs/2.8/html/gcode/overview.html#gcode:ini-hal-params
04:05 PM skunkworks: I did it a long time ago.. IIRC you need something in the ini?
04:05 PM JT-Shop: http://linuxcnc.org/docs/2.8/html/config/ini-config.html#gcode:ini-features
04:06 PM skunkworks: HAL_PIN_VARS = 1
04:06 PM JT-Shop: says it's default but I added HAL_PIN_VARS = 1 anyway
04:06 PM skunkworks: I remember it being different...
04:06 PM JT-Shop: hmmm
04:06 PM skunkworks: but maybe it changed.
04:06 PM skunkworks: I thought it was a mask of some kind
04:07 PM JT-Shop: yea I think I know what your talking about
04:07 PM skunkworks: FEATURES=12
04:07 PM JT-Shop: [NOTE] The above six options were controlled by the FEATURES bitmask in versions of LinuxCNC prior to 2.8. This INI tag will no longer work.
04:08 PM JT-Shop: 2.8 docs
04:09 PM skunkworks: heh
04:13 PM JT-Shop: hmm works in 2.7.15 but not in 2.8.0 or master...
04:13 PM skunkworks: JT-Shop: this worked in the 2.8 I have here..
04:13 PM skunkworks: g0x#<_hal[polygon.0.numsides]>
04:13 PM skunkworks: (moved x to 6 - what the pin was set to)
04:14 PM skunkworks: it is rip
04:15 PM JT-Shop: hmm
04:16 PM skunkworks: I just pulled the latest and am re-compiling
04:16 PM skunkworks: (it was from a few weeks ago)
04:18 PM JT-Shop: o100 if [EXISTS[#<_hal[motion-controller.time]>]]
04:18 PM JT-Shop: (debug, [motion-controller.time] exists: #<_hal[motion-controller.time]>)
04:18 PM JT-Shop: o100 else
04:18 PM JT-Shop: (debug, [motion-controller.time] does not exist)
04:18 PM JT-Shop: o100 endif
04:18 PM skunkworks: JT-Shop: still works in mdi
04:19 PM JT-Shop: hmm, I might need to update linuxcnc
04:21 PM skunkworks: (debug, [motion-controller.time] exists:#<_hal[motion-controller.time]>)
04:21 PM skunkworks: that like works in mdi..
04:27 PM skunkworks: JT-Shop: gcode works here if I run it.
04:27 PM skunkworks: my motion controller exists.. 8800
04:34 PM JT-Cave: https://pasteboard.co/Jql1xbP.png
04:35 PM JT-Cave: guess I need to install 2.8.0
04:39 PM skunkworks: heh
04:41 PM JT-Cave: guess I'll download the debian 10 iso in the morning during free time
08:06 PM CaptHindsight: Howto add a physical surface texture to an STL file? (not just a graphic or image)
08:06 PM CaptHindsight: Blender, Meshmixer?
08:07 PM JavaBean: salvaged xbone controller vibration motor?
08:07 PM JavaBean: just attach it to the hotend
08:08 PM CaptHindsight: JavaBean: you must be thinin of CNC glue guns
08:09 PM JavaBean: yeah, the hotend comment gave that away... should work with the whirling blades of death that you are using
08:11 PM CaptHindsight: JavaBean: what are you on?
08:11 PM CaptHindsight: shrooms?
08:12 PM JavaBean: probably fumes from just turning on the furnace for the first time in several months
08:12 PM CaptHindsight: hope you feel better
08:13 PM JavaBean: so do i... its almost a month early for a freeze, but i am sitting at 1912-ish and its already down to 47f outside
08:13 PM JavaBean: and it hit 90f here yesterday
08:14 PM XXCoder: 94f here today
08:14 PM XXCoder: smokey but not as bad as calfornia as oregon
08:28 PM CaptHindsight: https://firms.modaps.eosdis.nasa.gov/map/#t:adv;d:2020-09-09;@-46.2,3.7,3z lots of fires worldwide
08:28 PM CaptHindsight: surprised at how many
08:29 PM XXCoder: its getting to be a new season now
08:29 PM XXCoder: fall, winter, spring, summer, fire
08:30 PM JavaBean: fire season?? isn't it just a normal wednesday in california?
08:31 PM XXCoder: :( thats so amny fire
08:31 PM XXCoder: expecially in amazon
08:33 PM XXCoder: https://www.youtube.com/watch?v=kWbvqDzr2Bc TINY crt
08:45 PM unterhaus_: if it was a normal fire season, you could take a picture of the sky with your iphone and it wouldn't change the color
08:48 PM CaptHindsight: I haven't looked but maybe there is a pollution map showing particle density as a map overlay
08:49 PM CaptHindsight: https://aqicn.org/map/usa/
08:55 PM CaptHindsight: we are woopin China's buttocks in the bad air dept this week!
08:56 PM CaptHindsight: https://aqicn.org/city/usa/oregon/silverton/
08:58 PM CaptHindsight: 549 https://aqicn.org/city/california/mendocino/willits-justice-center
08:59 PM robotustra: I was thinking to buy a house with some forest
08:59 PM robotustra: now I have to think a little bit more
08:59 PM CaptHindsight: 834!! https://aqicn.org/city/california/plumas/chester/
09:00 PM CaptHindsight: robotustra: think stone and fire perimeter
09:00 PM CaptHindsight: or under water house
09:00 PM robotustra: or big field
09:01 PM robotustra: of grass
09:01 PM robotustra: trimmed and green
09:01 PM robotustra: and a stone walls
09:02 PM robotustra: surrounded with a trench around the wall filled with water
09:03 PM robotustra: it reminds me something
09:04 PM robotustra: https://images.app.goo.gl/7PfLXMN4fCK8yspy8
09:19 PM JavaBean: in minnesota my grandparents had a rather large chunk of forest... they did firebreaks throughout it to prevent forest fires. everyone did
09:30 PM roycroft: if they're minnesotans then they are of scandanavian descent
09:31 PM roycroft: so i'm sure they raked their forests on a regular basis
09:35 PM JavaBean: nope, just the yard... the firebreaks are "brush hogged" once a year
09:46 PM CaptHindsight: Pennsylvania dutch elm
09:52 PM roycroft: well, we have no northeasterly or easterly winds in our forecast for the next 10 days
09:52 PM roycroft: that can change in an instant, of course, but it's the first time in days that the wind is not forecast to come straight from the fires
10:04 PM JavaBean: wow, the wind has a bite
10:23 PM skunkworks: http://electronicsam.com/images/greenmachine/user-09Sep2020-22704.png
10:24 PM skunkworks: 2.8 buster - now trying isolcpus=3
10:43 PM Tom_L: nice
10:55 PM -!- #linuxcnc mode set to +v by ChanServ
11:03 PM ziper: anyone know anything about making hydraulics?
11:12 PM CaptHindsight: ziper: pst pst,over here, yeah, what dah yah need?
11:13 PM CaptHindsight: fluids, pumps, valves or cylinders?
11:14 PM ziper: I want to make a simple 2 piston push-pull system. I think I can get away with single acting cylinders because the pull force will be rather little. There will need to be a third cylinder so that I can set the displacement between the two working cylinders. The forces involved would be 20 pounds or so. The idea would be to eliminate linkage slop and friction in the current system. Is there anything like that off-the-shelf, or will I need to fabricate it?
11:16 PM CaptHindsight: how much travel?
11:16 PM ziper: 2 inches?
11:16 PM CaptHindsight: pneumatic good enough?
11:17 PM ziper: no, needs to be a stiff response
11:17 PM CaptHindsight: https://www.surpluscenter.com/Hydraulics/Hydraulic-Cylinders/Double-Acting-Hydraulic-Cylinders/1x4x0-375-DA-Hydraulic-Cylinder-9-7057-C.axd
11:27 PM ziper: someone else mentioned pneumatic cylinders, what is what I will try
11:27 PM ziper: lighter
