02:28 AM bjorkint0sh: moin moin
02:34 AM XXCoder: hey
03:08 AM lag: Tom_L: W1N9Zr0: I wish to *avoid* having to change the value in the *.ini file - I'd like to do this dynamically using (for instance) some of the values in the tool table
03:09 AM lag: If the value of '[TOOLSENSOR] Z' is too low, a large tool with crash into the sensor - if it is too high, a short tool will take forever to probe
03:10 AM lag: It would be nice if we could obtain a rough too; length and set the '[TOOLSENSOR] Z' value accordingly
03:11 AM lag: No I don't use probe_screenv2 - just the gmocappy built-in
03:29 AM CaptHindsight: lag: check back in an hour or two, when they might arrive
03:33 AM lag: CaptHindsight: I'm in no rush :)
05:10 AM JT-Cave: morning
05:18 AM XXCoder: hey
05:38 AM Tom_L: morning
05:38 AM XXCoder: hey
05:53 AM Tom_L: -9F
05:54 AM XXCoder: 38f and raining
05:54 AM XXCoder: snow is still here but wont be long
06:48 AM JT-Cave: hmmm my boots are in the machine shop...
07:18 AM JT-Cave: wow the high today is 7°F
07:47 AM lag: Tom_L: Did you see my messages above?
07:48 AM XXCoder: lag: i saw video where theres 2 stage tool measure thing
07:48 AM XXCoder: first stage is using laser
07:48 AM lag: XXCoder: :)
07:48 AM XXCoder: then second stage is touch off plate press
07:48 AM lag: Let's not go crazy :)
07:48 AM XXCoder: video I saw is simple design
07:48 AM XXCoder: the demo is scary, it rapids into exactloy above vise heh
07:49 AM lag: I just want a way to tell LinuxCNC if it's using a short or long tool - so it doesn't take ~1min to do tool length sensing
07:49 AM lag: XXCoder: I'd like to see the video in any case - but this is not what I'm looking for :)
07:49 AM XXCoder: ok will try find dunno if can
07:50 AM lag: XXCoder: No pressure - it's just for interest
07:50 AM XXCoder: oh new one https://youtu.be/SI2NClO7Y30
07:50 AM XXCoder: "one stage" except its faster on laser part, when its triggered it slows down
07:54 AM lag: XXCoder: Okay, so he is solving the problem I described
07:55 AM XXCoder: yeah
07:55 AM lag: XXCoder: I guess, seeing as he has gone to a lot of effort to solve this, that LinuxCNC cannot do this using natively using the tool table :(
07:55 AM lag: Bugger!
07:55 AM XXCoder: seems not
07:56 AM lag: Okay, next question
07:56 AM lag: Does anyone know if you have a static tool sensor?
07:57 AM lag: At the moment LinuxCNC tried to eat my sensor after touch-off
07:57 AM lag: Or do you have to set the height of the sensor as the Clearance Height on the G-Code creator?
08:01 AM miss0r: hello
08:01 AM miss0r: Looking like we're gonna get alot of snow tonight.
08:01 AM XXCoder: lag dunno never setup tool measure system im sure someone knows evenually :)
08:01 AM XXCoder: mis yeah here snowed a lot, but melting under rain now
08:02 AM lag: XXCoder: Do you have repeatable tooling?
08:02 AM XXCoder: doubt it will come back, its very rare to have 8" lol (its rare enough to have 1")
08:02 AM XXCoder: nah its manual
08:02 AM miss0r: I have one of these Metrol t20b-14-22h, I'm gonna setup for just that soon
08:04 AM miss0r: it promises 0.001mm repeatability
08:04 AM miss0r: but in my experience you cannot count on it for more than double that
08:05 AM XXCoder: for .001mm repeatability you would need it to measure .0001mm pretty reliabily
08:05 AM miss0r: well.. its a good switch. and they cost a fortune. I only have mine because I took it off a machine because the air nozzle broke off.
08:05 AM miss0r: and I machined a new one for it.
08:06 AM XXCoder: yeah for homing .001mm should be reasonable
08:06 AM XXCoder: after all it shouldnt be triggered once per power up
08:06 AM miss0r: a bit overkill for my setup anyway :)
08:06 AM XXCoder: *more than once
08:07 AM miss0r: indeed. I actualy only use it for setting tools when they are replaced.
08:07 AM miss0r: the mill keeps track of my tools
08:07 AM XXCoder: nice
08:08 AM miss0r: lol, all the sites that sell it online wants me to write them for a quote. But I know that the last one I replaced was aprox $4k usd
08:09 AM miss0r: not something I would ever buy new for myself. :D
08:10 AM JT-Cave: we got about 4" of powder snow last night
08:31 AM Tom_L: starting to snow again here
08:31 AM Tom_L: -9F
08:33 AM JavaBean: 10f, far west texas... windchill advisory has been modified to end at 0900. 40mph winds warned which could drop the windchill to -25f
08:58 AM Centurion-Dan2 is now known as Centurion_Dan
09:03 AM MarcWeber: I'd like to engrave into glass. What is the fastets way to turn b/w image into g code ? Inkscape's gcodetools seem to work but also seem to be very slow. I have the feeling that just rendering SVG with many small artefcats (results of image tob/w) wuld be faster if it would look at pixels rather than intersections.
09:24 AM JT-Shop: it's actually warmer in the big shop this morning.... 41 here 48 out there
09:31 AM roycroft: it's 10 degrees here already
09:31 AM roycroft: busy day today - i have to go to a data center in a minute, and i have to pick up my new saw right after work
09:32 AM roycroft: but give how war it is, i should be able to bring the parts i painted over the weekend inside the house this morning
09:35 AM roycroft: warm, rather
09:35 AM roycroft: it doesn't feel very warry here
09:41 AM JT-Shop: we are half way to the high for today 6F was 5F
09:44 AM roycroft: brr
09:44 AM roycroft: i don't miss living back east at all
09:44 AM roycroft: and the winter weather is one of the big reasons
09:58 AM htasta: lag: you could use #<_selected_tool> to check what tool number it is to go closer to the probe with smaller tools.
09:59 AM htasta: for example you could give all small tools a number above 100 and all long ones one below 100
09:59 AM JT-Shop: it's snowing real hard now and I need to go change the water in the coops
09:59 AM htasta: you can make different categories like below 100 is long above 100 and below 200 is medium etc..
10:07 AM htasta: lag: you could also add additional parameters to your remaped tool change code. so if you remapped M6 to your tool probe routine you could define it to take an aditional parameter f.e. L and change a tool like this:
10:07 AM htasta: M6 T1 L50
10:08 AM htasta: in your M6 tool probe routine you can then read the L parameter and rapid the 50mm or whatever you use towards the probe
10:13 AM htasta: http://linuxcnc.org/docs/html/remap/remap.html#_the_argspec_parameter
11:23 AM lag: htasta: Hmm... I might try that
11:23 AM lag: htasta: I was kinda hoping for a less bespoke approach, but that could work if there is no officially support way to achieve what I'm after
11:23 AM lag: Either that or I just suffer the 1min lag for tool changes
11:24 AM htasta: hahaha
12:28 PM Tom_itx: brrrr....
12:28 PM Tom_itx is now known as Tom_L
12:29 PM * JT-Shop attempts to get some machining done in between hauling wood and water
12:30 PM Tom_L: made the morning rounds.. afternoon can just suck it
12:30 PM Tom_L: somebody should make a big hot pot of chili
12:31 PM JT-Shop: got the chili in the freezer
12:32 PM Tom_L: i'd say set it outside to thaw but it wouldn't
12:32 PM JT-Shop: still getting heavy snow here
12:54 PM roycroft: apparently we just missed a lot of snow
01:13 PM JT-Shop: looks like Friday we will get mail and packages
01:14 PM roycroft: that's a long time to wait
01:14 PM roycroft: sounds almost like me
01:14 PM roycroft: my edge sanding guide has already shipped
01:15 PM roycroft: i'm so looking forward to getting that
01:15 PM roycroft: being able to sell my 6x80 edge sander will really clear up a lot of space in my shop
01:15 PM JT-Shop: no mail or packages since last wednesday
01:15 PM roycroft: things are actually getting a little better here
01:15 PM roycroft: mail is arriving after 5pm some days
01:16 PM JT-Shop: got a link to the edge sanding guide?
01:16 PM roycroft: so apparently the no overtime rule is on hold or revoked
01:16 PM roycroft: https://www.amazon.com/gp/product/B08CGY8FJZ/
01:16 PM roycroft: it was announced last summer, but i did not pre-order
01:17 PM roycroft: and they just now became generally available
01:17 PM roycroft: i already have an ets 125 req, which that fits
01:17 PM roycroft: so that will replace this:https://www.grizzly.com/products/grizzly-6-x-80-floor-model-edge-sander/g1140
01:18 PM roycroft: well
01:18 PM roycroft: the new edge guide + my 2x72 belt grinder
01:21 PM JT-Shop: can you control the depth of cut?
01:22 PM roycroft: no
01:23 PM roycroft: i only use the 6x80 for sanding narrow edges these days, and i'll be able to use the edge guide for that
01:23 PM roycroft: it will be nice for doing chamfers too, i think, without having to pull out a noisy, messy router
01:24 PM roycroft: but if all i can reasonably do is square 90s with it it's still worth the money easily
01:30 PM JT-Shop: interesting
01:31 PM miss0r: bah. here I was hoping for a proper blizzard.. Its now mostly over and it only dropped 10cm/4"
01:31 PM miss0r: I don't even want to take the land rover out into that. I could do that in my skoda...
01:33 PM JT-Shop: still snowing hard here
01:34 PM miss0r: I envy you :)
01:34 PM miss0r: Its been forever since I had some real snow to push through in my 4x4
01:34 PM miss0r: and I realy rather enjoy that
01:37 PM JT-Shop: great I can follow my non-delivery by ups on a map
01:37 PM JT-Shop: and watch him go by
01:37 PM miss0r: lol nice
01:38 PM JT-Shop: yea the truck is still parked at the ups hub in town
01:41 PM miss0r: because of the snow?
01:45 PM JT-Shop: probably, also the south end of the road I live off of has a lot of ice on it... the north end is always ok...
01:50 PM JT-Shop: I can't tell if it's still snowing or just the wind blowing it around
02:26 PM Tom_L: JT-Shop, will they hold the packages for a sunny day or return them?
02:44 PM roycroft: we'll ship again, don't know where, don't know when
02:44 PM roycroft: but i know we'll ship again some sunny day
02:47 PM JT-Shop: Tom_L, dunno
02:47 PM JT-Shop: local power coop just issued a peak warning so may loose power here
02:49 PM Tom_L: got a generator?
02:49 PM JT-Shop: 3
02:52 PM JT-Shop: big one is 15Kw 3 phase...
02:53 PM Tom_L: propane?
02:54 PM JT-Shop: diesel
02:54 PM JT-Shop: 2 cyl
03:23 PM JT-Shop: https://gnipsel.com/images/house/generators/15Kw-01.jpg
03:33 PM Tom_L: my friend got a 15kw from a closing grocery store
03:36 PM JT-Shop: started up with a squirt of ether
03:36 PM JT-Shop: this one came from a small police station
03:37 PM roycroft: who in turn had gotten it in a forfeiture from a meth house owner
03:38 PM roycroft: at least that's how the cops around here get all their stuff
03:43 PM roycroft: i am looking for some small threaded inserts - the kind that are often embedded in plastic, made of brass, with the outside straight knurled
03:44 PM roycroft: not the expanding type
03:44 PM roycroft: does anyone know of a good source for those?
03:44 PM Tom_L: ali
03:44 PM Tom_L: i'm sure mcmaster probably has them too
03:44 PM roycroft: mcmaster don't seem to
03:44 PM roycroft: a good domestic source :)
03:45 PM Tom_L: https://www.ezlok.com/e-z-lok-brass-threaded-inserts
03:45 PM roycroft: none of the ezlock products are exactly what i'm looking for
03:46 PM Tom_L: https://www.amazon.com/E-Z-Lok-Threaded-Insert-Products/dp/B08GYYL7Y4
03:46 PM roycroft: i'll be inserting them in hardwoods, with some epoxy
03:46 PM roycroft: they're for 4-40 screws, and i need the inserts to be as small in diameter as possible
03:46 PM roycroft: so the type with threads on the outside won't work
03:46 PM Tom_L: to small and it won't stay put
03:47 PM roycroft: i suppose i can make them
03:47 PM Tom_L: thread geometry somewhat dictates size
03:47 PM roycroft: that's what the knurls are about
03:47 PM roycroft: and the epoxy
03:47 PM roycroft: think of brass inserts that get pressed into plastic parts
03:47 PM Tom_L: https://www.mscdirect.com/industrialtools/threaded-brass-inserts.html
03:49 PM Tom_L: they've got 2-56
03:49 PM Tom_L: https://www.mscdirect.com/product/details/93442036
03:50 PM Tom_L: search that first page for #4 and you'll find several
03:50 PM roycroft: https://www.amazon.com/Pem-Molded-Threaded-Inserts-Blind/dp/B00VMUIT8W/
03:50 PM roycroft: those would probably work
03:50 PM roycroft: i don't need 100 of them though
03:51 PM Tom_L: yet
03:51 PM roycroft: but that's close to what i'm looking for
03:52 PM roycroft: i need six right now
03:52 PM roycroft: a ten pack would be nice
03:55 PM roycroft: https://www.ebay.com/itm/153394546887
03:56 PM roycroft: that's exactly the kind i'm looking for, except those are metric (i could deal with that if i had to) and from china (i'd rather not)
03:58 PM Tom_L: https://catalog.pemnet.com/item/straight-knurl-inserts-types-pka-pkb/press-in-threaded-inserts-straight-knurl-unified/pkb-440
03:58 PM roycroft: so maybe i'll just make some - i think i have some brass rod that will work
03:59 PM Tom_L: got a straight knurl?
04:00 PM roycroft: yes
04:04 PM _unreal_: hate to do it but I have to PROBE out the damn wires once I get that figured out I can finish my pcb design
04:04 PM _unreal_: and get that pcb milled
04:06 PM JT-Shop: couldn't shut the generator down the stop button was stuck...
04:06 PM _unreal_: flip the gas switch off
04:06 PM _unreal_: let is run out
04:07 PM JT-Shop: roycroft, from all the paperwork that came with the generator I highly doubt they got it that way
04:07 PM roycroft: it's diesel, _unreal_
04:07 PM roycroft: it's always a bad idea to run a diesel engine dry
04:08 PM _unreal_: lol always a fun time
04:08 PM JT-Shop: sometimes I wonder what I missed then most of the time I don't
04:08 PM _unreal_: well diesel in general yes but small motors like that are less prone to issues with running the lines dry
04:09 PM _unreal_: not hard to prime them ether
04:09 PM _unreal_: I assume a single cylender
04:09 PM _unreal_: cylinder
04:09 PM Tom_L: 2
04:09 PM _unreal_: even soo
04:23 PM roycroft: i repeat: it's always a bad idea to run a diesel engine dry
04:51 PM htasta: lag: I uploaded an example change.ngc for you with how I think it could work: https://bombocla.at/cnc/change.ngc
04:51 PM htasta: you also need to adjust the M6 remap command in the ini to the one here: https://bombocla.at/cnc/ini.txt
04:52 PM htasta: the changes I made are on line 37 to 43.the probe_distance is the distance from spindle to probe with a tool of length 0
04:53 PM htasta: the safety_distance is extra space left between probe and tool for the slow probing
04:54 PM htasta: probe_distance is measured when the Z is at position 0 not [TOOLSENSOR]Z from the ini, you should set that in the ini to 0
04:55 PM htasta: I haven't tested any of this so you might need to adjust something, but I think it makes the general idea clear
04:55 PM htasta: use it like this to change the tool:
04:55 PM htasta: T1
04:55 PM htasta: M6 L50
04:55 PM htasta: change to tool 1 with an aprox. length of 50mm
04:59 PM lag: Interesting, thanks for doing that
05:00 PM lag: I'll see if I can get FreeCAD to output that
05:00 PM JT-Cave: lag, it's not unusual to use 1xx in the tool table for special things
05:00 PM JT-Cave: 1xx, 2xx 3xx etc
05:00 PM lag: In what col?
05:00 PM lag: Tool number?
05:01 PM JT-Cave: tool number
05:01 PM lag: Okay, well I set that manually, so we should be all set
05:01 PM JT-Cave: like htasta is explaining
05:02 PM lag: It's bed time here and it's been a REALLY long day, so I'm a bit hazey - I'll look again tomorrow with fresh eyes
05:02 PM lag: Thanks again - will ping tomorrow if I have any Qs
05:04 PM * roycroft looks for items to pad out a mcmaster order, to make it worth the shipping cost
05:13 PM roycroft: it's time to go pick up the saw
05:13 PM htasta: gn8
05:13 PM roycroft: something else to store
05:13 PM roycroft: in my shop that has no storage space
05:15 PM JT-Cave: my oldest daughter in Houston has been out of power all day and had to boil water on her bbq pit to have some warm food and coffee
05:17 PM roycroft: yeah, i read that literally over half the population of the us are under winter storm warnings and tens of millions are without power all cross the country
05:17 PM roycroft: it's just windy here, thank goodness
05:18 PM JT-Cave: we made it to 9°F today
05:18 PM roycroft: actually, we have 320,000 people without power here in oregon
05:18 PM roycroft: the portland metro area got hit badly by the snow
05:19 PM roycroft: texas alone has almost 4 million without power
05:19 PM roycroft: it is still 10 degrees here
05:19 PM roycroft: it was 10 degrees when i woke up this morning
05:19 PM roycroft: 10 degrees when i went to lunch
05:20 PM roycroft: i'm thinking that ten is today's number
05:20 PM roycroft: and the forecast highs are 10 tomorrow, 10 wednesday, and 10 thursday
05:20 PM roycroft: i guess i should get used to 10
05:21 PM * roycroft heads off
05:25 PM JT-Cave: -13 in roycroft measurements here
05:28 PM Tom_L: i think we may have hit 0F
05:29 PM JT-Cave: we get that tonight
05:29 PM Tom_L: bottle some up for summer
05:31 PM JT-Cave: crap I gotta go out one more time in the snow... I'm so tired of it already
05:31 PM Tom_L: don't have a beaten path to follow yet?
05:32 PM JT-Cave: pretty much shoveled out paths
05:33 PM Tom_L: saw a yt a guy did a bunch of paths for his dogs to have a run
05:35 PM JT-Cave: my dog used to love snow she would run and dip her nose in it
05:35 PM Tom_L: one of mine loves it the other not so much
05:35 PM Tom_L: yeah, she eats it
05:37 PM Tom_L: last few days, they've been rather quick on their outtings
05:37 PM Tom_L: -t
05:59 PM CaptHindsight: warmup later in the week \0/
06:04 PM JT-Cave: hmm wonder if CaptHindsight has notice that my position logger does positions by time...
06:05 PM CaptHindsight: heh, I did
06:05 PM JT-Cave: lol
06:05 PM JT-Cave: still working on making a deb for it
06:05 PM CaptHindsight: i was just putting the different projects in one place
06:06 PM CaptHindsight: ends up they are lazy and just want me to program all the tool paths
06:06 PM JT-Cave: lol
06:06 PM CaptHindsight: "just make it push button"
06:07 PM * JT-Cave retires to the couch
06:07 PM CaptHindsight: OK so every time you guys have a new profile someone will have to come out and program the machine
06:07 PM CaptHindsight: YES
06:32 PM roycroft: yay! i has giant saw!
06:53 PM Jymmm: lol
07:36 PM * flyback bites puff
07:36 PM flyback: CANUCK
07:42 PM Tom_itx is now known as Tom_L
08:21 PM Tom_L: so who else is in the SW power pool?
08:21 PM Tom_L: https://apps.evergy.com/message/
08:26 PM Tom_L: https://www.google.com/imgres?imgurl=https%3A%2F%2Fs3.amazonaws.com%2Fcoop-nipco-cdn%2Fcontent%2FSPP-WAPA_Footprint-RED-09042015.png%3Fmtime%3D20161205201419&imgrefurl=https%3A%2F%2Fwww.nipco.coop%2Fwe-power-rural-iowa%2Fsouthwest-power-pool&tbnid=goCSas3UINX86M&vet=12ahUKEwjD2LuWqu3uAhUQL60KHXtfBQEQMygBegUIARCpAQ..i&docid=CLPzhY51GuluqM&w=612&h=792&q=southwest%20power%20pool%20map&client=firefox-b-1-d&ved=2ahUKEwjD2LuWqu3uAhUQL60KHXtfBQEQMygBe

08:28 PM XXCoder: roycroft: and hockey mask?
08:30 PM roycroft: the saw is safely in its box
08:30 PM XXCoder: lol
08:30 PM roycroft: i fitted the front rail of my bandsaw fence to the table today
08:31 PM roycroft: i need some fasteners from mcmaster before i can do the back rail, though
08:31 PM roycroft: i think it's safe to send the table to paint anyway - i did drill and tap the holes in it
08:32 PM roycroft: and when i "send parts to paint" that means i take my machinst's apron off and put my painting hat on
08:32 PM Tom_L: did you mask the threads?
08:32 PM roycroft: i have silicone plugs that i stick in threaded holes before i paint
08:33 PM roycroft: https://www.mcmaster.com/2903K19/
08:33 PM roycroft: that type
08:34 PM roycroft: except i have a set of them in about a dozen sizes
09:10 PM flyback: nice
09:19 PM roycroft: still well over 300,000 customers without power in oregon
09:20 PM XXCoder: :(
09:20 PM roycroft: i like having just missed the storm
09:20 PM roycroft: i'm actually watching the local news on television - something i rarely do
09:20 PM roycroft: but portland is a huge mess
09:21 PM roycroft: and it's kind of interesting watching the mayhem
10:10 PM unterhaus_: I put a light on my lathe carriage. There was a block bolted to it with no apparent purpose, so I used that
10:10 PM XXCoder: nice
10:11 PM XXCoder: roy last i heard oregon improved electric system finally, but guess not completely
10:11 PM unterhaus_: I had a power supply for a monitor that fits the 3d printer
10:11 PM unterhaus_: gotta check the polarity before I try it
10:11 PM unterhaus_: 6.4 amps though
10:11 PM XXCoder: yeah i can look againb if you need me to
10:12 PM XXCoder: that should be ok, just dont try petg
10:12 PM XXCoder: it can just barely do petg with 7a
10:12 PM unterhaus_: I should look through my power supply collection, I tripped on this one
10:12 PM unterhaus_: oh, is that 12v?
10:13 PM XXCoder: 12v yeah
10:13 PM unterhaus_: I mean after I tripped on it
10:13 PM XXCoder: i wonder if it can use higher volt heh
10:13 PM roycroft: a pge spokesperson said they had more than twice as many workers in the field restoring power than they've ever had before
