12:26 AM unclouded_ is now known as unclouded
02:32 AM Deejay: moin
02:39 AM CaptHindsight[m]: https://forum.linuxcnc.org/38-general-linuxcnc-questions/47642-gentoo-image-which-applications-are-in-and-which-are-out
02:40 AM XXCoder: I dunno on lack of audio support
02:40 AM XXCoder: while im deaf, I think of alarms or music while its running
02:41 AM CaptHindsight[m]: i read through comments on the forums about audio
02:42 AM CaptHindsight[m]: most disable audio in BIOS so that it doesn't effect latency
02:42 AM XXCoder: ahh makes sense I guess
02:42 AM Deejay: my mill makes enough noise, i dont need more audio ;)
02:42 AM CaptHindsight[m]: but I'm waiting to hear :) what people have to say about it
02:42 AM XXCoder: dee hard metal music eh
02:43 AM Deejay: hehe
02:43 AM CaptHindsight[m]: what music does LCNC play?
02:43 AM CaptHindsight[m]: Metal of course
02:43 AM CaptHindsight[m]: the official bad joke of LCNC
02:44 AM CaptHindsight[m]: no USB auto mounting
02:44 AM CaptHindsight[m]: is that going to effect some people?
02:45 AM XXCoder: depends. if you use network to share files, or do cam right there at lcnc machine, probably not
02:45 AM CaptHindsight[m]: having to manully mount a USB drive?
02:45 AM CaptHindsight[m]: also NO NTFS support
02:45 AM CaptHindsight[m]: NFS
02:45 AM CaptHindsight[m]: Samba
02:45 AM XXCoder: if you setup stuff on different pc then move it via usb drive often then it is likely to affect person doing that
02:46 AM XXCoder: not too bad if you use third party file sender
02:46 AM XXCoder: like filezilla or something for windows
02:47 AM XXCoder: samba is huge overhead. file send and get probably is much smaller footprint
02:47 AM CaptHindsight[m]: he is actually trimming down a previous Gentoo image for this
02:48 AM XXCoder: replied there
02:48 AM CaptHindsight[m]: how do most transfer their g-code programs to their LCNC machine?
02:48 AM XXCoder: on job I had before last one, we used filezilla
02:48 AM CaptHindsight[m]: 👍️
02:48 AM XXCoder: last job, either usb drive or server download program
02:49 AM XXCoder: most common latter
02:49 AM CaptHindsight[m]: so with a browser, pint, click, download
02:49 AM CaptHindsight[m]: pint/point
02:49 AM XXCoder: it just looks like file browser
02:50 AM XXCoder: (filezilla)
03:00 AM XXCoder: last job most machines had its own weird method to download program. some of em thinks its connected to tape machine
03:00 AM CaptHindsight[m]: we will see what happens after people give it a try
03:00 AM XXCoder: yeah
03:00 AM CaptHindsight[m]: the good part about using Debian is all the apps you can install
03:00 AM CaptHindsight[m]: the bad part about using Debian is all the apps you can install :)
03:00 AM XXCoder: lol
03:20 AM sensille: no samba? i upgraded my installation just to get a working samba again (v1 deprecation)
04:58 AM travis_farmer: G'Morning
05:05 AM JT-Cave: morning
06:02 AM travis_farmer: currently 10F, with a high of 23F. not a good day to work outside... here, anyway
06:56 AM travis-farmer: i really hate this laptop... i think the wifi card is crapping out, as i keep getting disconnected from the wifi... really quite aggravating.
06:58 AM travis-farmer is now known as travis_farmer
07:32 AM CloudEvil: usb wifi can be an answer
07:36 AM JT-Cave: I guess it depends on how well your shop is insulated... I heat 21,750 cubic feet of shop with a couple of sticks of wood
08:10 AM Tom_L: morning
08:34 AM perry_j1987: morning
08:48 AM perry_j1987: got a small cinderblock building here about 12x15 inside dimensions
08:49 AM perry_j1987: like to add heat and use this winter
08:55 AM sensille: nothing beats good documentation ... https://i.imgur.com/L5TthGk.jpg
09:11 AM JT-Shop: perry_j1987, the more insulation you put in there the easier it is to heat and cool
09:11 AM Tom_L: sensille, google translate
09:12 AM Tom_L: JT-Shop, very true
09:12 AM perry_j1987: JT-Shop aye
09:12 AM Tom_L: the pilot will keep it above freezing in the garage
09:12 AM Tom_L: even in the teens
09:12 AM sensille: Tom_L: well, the color names are in english. they just don't match the wire
09:13 AM Tom_L: well then, roll the dice again
09:13 AM travis-farmer: my shop is currently a gutted out camper... 1.5 inches of insulation, tops.
09:14 AM Tom_L: geen :)
09:16 AM Tom_L: JT-Shop, decide on a bowl pattern?
09:16 AM Tom_L: looks like a fun project
09:17 AM JT-Shop2: no, still pondering the pattern
09:18 AM Tom_L: found the push isssue... wifi doesn't work on buster but does on bookworm on the rpi
09:18 AM Tom_L: but
09:18 AM Tom_L: i was able to download the changes on buster with wifi
09:19 AM Tom_L: sensille, you sure that's the right schematic? looks like you're missing some wires
09:22 AM sensille: oh, you're right, the upper schematic might be the right one
09:22 AM Tom_L: you could ohm that one out
09:23 AM sensille: yeah. i just thought it is funny. wrong colors, wrong number of wires
09:24 AM JT-Shop2: my first shop was a closet in my apartment
09:24 AM JT-Shop2: a very small closet
09:25 AM Tom_L: it grew
09:25 AM Tom_L: foggy out today
09:26 AM Tom_L: 31F
09:27 AM JT-Cave: 43°F fog/mist/overcast
09:33 AM travis-farmer: 19F and sunny
09:35 AM travis-farmer: sensille: what do those wires go to? looks the same as a tool length sensor i had...
09:36 AM sensille: travis-farmer: right
09:38 AM travis-farmer: red = protection (estop), yellow = tool sensor, green = ground, black = power. that is what i made a note of on my schematic
09:39 AM markgonz: hello everyone, first timer here :)
09:39 AM markgonz: Im building a small cnc mill for making watch parts
09:40 AM markgonz: just got the mesa 7i96s and I
09:41 AM markgonz: am following the feral engineer youtube tutorial for a celeron minipc
09:43 AM markgonz: however can´t install grub customizer
09:45 AM Tom_L: ubuntu?
09:45 AM markgonz: I installed debian live 11.5 cinnamon non free iso
09:46 AM markgonz: but I´m a noob so probably I did something wrong
09:47 AM JT-Shop2: markgonz, https://gnipsel.com/linuxcnc/index.html
09:47 AM JT-Shop2: https://gnipsel.com/linuxcnc/mesact/index.html
09:48 AM Tom_L: being a noob, i'd follow a known path as jt recomends
09:48 AM Tom_L: you're more likely to get the needed help
09:50 AM sensille: travis-farmer: thanks :)
09:50 AM markgonz: ok I understand, first idea was to follow the tutorial and see if it just works, but following the documentation makes more sense
09:51 AM markgonz: thanks for the link JT-shop
09:51 AM travis-farmer: no problem sensille, glad i could help :-)
09:51 AM sensille: black = power. how intuitive
09:52 AM travis-farmer: lol, yes, i know
10:05 AM JT-Shop2: markgonz, you're welcome and that is my tutorial and Mesa Configuration Tool
10:05 AM Tom_L: jt you do some more updates this AM?
10:05 AM JT-Shop2: yup, fixed a few self induced bugs :)
10:05 AM Tom_L: ok i'll build
10:05 AM JT-Shop2: thanks
10:07 AM JT-Shop2: I need to write a pyqt5 program for my polygon calculator open office takes far too long to load
10:20 AM Tom_L: JT-Shop2, the 'open any ini' fails
10:21 AM sensille: interesting. i can get differential step/dir output by having the stepgen pins on 2 pins on the mesa card. then i get invert_output independent on each of the 2 pins. is that how it is meant to be used?
10:22 AM Tom_L: JT-Shop2, http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/mesact/mesact112_error.png
10:24 AM JT-Shop2: hmmm
10:24 AM JT-Shop2: post your ini file
10:24 AM Tom_L: it's my mill
10:24 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.2/
10:24 AM Tom_L: should be the same
10:25 AM JT-Shop2: ok
10:25 AM Tom_L: the one built by you opens fine
10:25 AM Tom_L: i've got alot of crap in mine
10:25 AM Tom_L: comments, old tests etc
10:25 AM Tom_L: should all be commented out
10:26 AM Tom_L: and
10:26 AM Tom_L: there are 2 configs in that dir
10:26 AM Tom_L: anything with _A is for the rotary
10:27 AM Tom_L: it opens the axis sim fine
10:28 AM Tom_L: i'm betting my config would be a 'worst case'
10:30 AM JT-Shop2: ok
10:31 AM Tom_L: i tested spindle orient etc and left that in the file but i'm not using it
10:31 AM Tom_L: for tool changer code
10:37 AM Tom_L: i'll wait on the build
10:42 AM unterhaus: do you have to have a RT kernel to do a sim?
10:42 AM Tom_L: no
10:42 AM Tom_L: not that i'm aware of
10:44 AM JT-Cave: [HALUI]
10:44 AM JT-Cave: MDI_COMMAND = O<work_zero> call
10:44 AM JT-Cave: MDI_COMMAND = G10 L20 P1 X0
10:44 AM JT-Cave: MDI_COMMAND = G10 L20 P1 Y0
10:44 AM JT-Cave: MDI_COMMAND = G10 L20 P1 Z0
10:44 AM JT-Cave: MDI_COMMAND = O<work_zero_xy> call
10:44 AM JT-Cave: ###MDI_COMMAND = G10 L20 P1 X0 M100
10:44 AM JT-Cave: ###MDI_COMMAND = G10 L20 P1 Y0 M100
10:44 AM JT-Cave: ###MDI_COMMAND = G10 L20 P1 Z0 M100
10:44 AM JT-Cave: I didn't parse that section correctly
10:44 AM Tom_L: ahh
10:45 AM Tom_L: makes me wonder what i was doing with the ###MDI_COMMAND = G10 L20 P1 Z0 M100 lines
10:45 AM JT-Cave: see if you can break it now :)
10:45 AM Tom_L: custom Mcode
10:45 AM JT-Cave: dunno but glad you did
10:45 AM Tom_L: hah
10:46 AM Tom_L: building
10:47 AM Tom_L: the hal is an even bigger mess..
10:48 AM JT-Cave: hmm I need to do one more thing, put the ini in the backup directory before building so a new ini file is created
10:48 AM Tom_L: it opens now
10:51 AM Tom_L: can't do much with it but it opens
10:52 AM Tom_L: which i fully expected
10:53 AM JT-Cave: good
10:54 AM Tom_L: you're not reading the sections in yet
10:54 AM Tom_L: well, some of them
10:54 AM Tom_L: and i'm using a custom bit file so that doesn't help either
10:55 AM Tom_L: it read in the mdi commands
10:56 AM Tom_L: the velocities
11:00 AM Tom_L: you'd have to add the custom bit file & 7i47s to the daughter card for me to test the axis entries
11:02 AM JT-Cave: ok that should be better
11:02 AM JT-Cave: 7i80hd?
11:02 AM Tom_L: yes 16
11:03 AM Tom_L: i think i load the a axis bitfile for both now
11:03 AM JT-Cave: must be a bug it
11:03 AM Tom_L: in what?
11:03 AM JT-Cave: 's not loading the firmware for 7i80hd16
11:04 AM JT-Cave: enter key is too close to the ' key
11:04 AM JT-Cave: lol
11:04 AM Tom_L: i don't think you finished the list for the 7i80hd16
11:04 AM Tom_L: not that i remember...
11:04 AM Tom_L: but i can't remember what i did 10 min ago..
11:04 AM JT-Cave: it "should" load the firmware I "think"
11:04 AM Tom_L: not if you don't have it in the list
11:05 AM Tom_L: yeah, i think the bitfile is on the server too
11:06 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.2/Bitfiles/7i80/
11:07 AM Tom_L: no, the A axis isn't there
11:08 AM JT-Cave: it was a dash issue... 7i80hd-16 should have been 7i80hd16 because the directory is that name
11:08 AM Tom_L: oh
11:09 AM Tom_L: i forgot how to make a pin file..
11:09 AM JT-Cave: the combobox data was wrong
11:09 AM Tom_L: i'll make one for this if you refresh my memory
11:09 AM JT-Cave: I'm not sure if I'm better at breaking it or fixing it :)
11:09 AM * JT-Cave heads back to the shop
11:10 AM unterhaus: diacro has price lists on their website with all the prices blank
11:11 AM unterhaus: name of the document ends with "prices_being_updated"
11:12 AM JT-Shop2: Tom_L, the only thing that puzzles me is why the axis letter is not found for an unknown or pnc ini file
11:12 AM JT-Shop2: they have a mistook it should read "prices being raised again"
11:13 AM unterhaus: I'm sure they meant something like that
11:13 AM unterhaus: or "if you have to ask"
11:14 AM unterhaus: I was looking for a part somewhere else and someone said, "I know it's only $280"
11:14 AM unterhaus: I only spent $1000 on the bender, $280 for a small part seems like a lot
11:17 AM JT-Shop2: which bender?
11:20 AM Tom_L: JT-Shop2, do you recall what the board name for the new version of mesaflash for the 7i80 is?
11:20 AM Tom_L: i know it changed
11:20 AM Tom_L: i just can't find my notes
11:23 AM JT-Shop2: 7i80 should be the same I think
11:23 AM Tom_L: i think he changed it after 3.4.3 or thereabouts
11:24 AM Tom_L: when he added the new fpgas
11:26 AM JT-Shop2: hmm, dunno
11:26 AM Tom_L: ahh!
11:27 AM Tom_L: 7i80HD-16
11:27 AM Tom_L: had the - in the wrong place
11:27 AM Tom_L: in case you're putting that in your tool, you may wanna take note of that
11:28 AM Tom_L: you'd have to ask him what version the change was made in
11:28 AM Tom_L: but i think it was after 3.4.3
11:29 AM JT-Shop2: see if you can readhmid on the 7i80
11:29 AM JT-Shop2: I don't have any I don't think
11:29 AM Tom_L: no board found
11:29 AM Tom_L: i'm running 3.4.6 i think
11:30 AM JT-Shop2: I see a bug in https://github.com/jethornton/mesact/blob/master/mesact/src/libmesact/card.py#L37
11:30 AM JT-Shop2: https://github.com/jethornton/mesact/blob/master/mesact/src/libmesact/card.py#L42
11:30 AM JT-Shop2: I think that's wrong
11:31 AM * JT-Shop2 puts the greenlee punch away then takes a nap
11:32 AM Tom_L: ok i got a pin file for the custom bit i'm running
11:38 AM Tom_L: JT-Shop2, not sure (need more testing) but when you make the backup i think the original files are removed except the main.ini and main.hal
11:42 AM JT-Shop: backup from a mesact configuration?
11:44 AM unterhaus: getting a solidworks military license is a much bigger pain in the butt since last year
11:45 AM Tom_L: JT-Shop, i think so
11:45 AM Tom_L: on the 'read any ini' one
11:45 AM unterhaus: got to upload your dd214
11:45 AM Tom_L: JT-Shop, yes, i double checked...
11:46 AM Tom_L: couldn't figure out where all my files went !
11:46 AM Tom_L: it leaves the 2 ini files but removes the rest
11:49 AM JT-Cave: opps
11:50 AM Tom_L: well at least you made a backup :)
11:53 AM JT-Cave: if the config is not created by mesact then I have to delete the old files... I should warn about that
11:53 AM Tom_L: that _would_ be the polite thing to do :)
11:53 AM roycroft: jt-cave: do you mind putting your electrician's hat on for a moment?
11:54 AM Tom_L: ok the config works. hadn't tested the 7i80 in some time
11:54 AM Tom_L: and got a pin file for it
11:55 AM JT-Cave: for a moment it's dangerously close to nap time
11:55 AM roycroft: ok
11:55 AM roycroft: i'm trying to sort how to wire my winch
11:55 AM roycroft: it's going to be a ~20' fun from the batteries in the front of the truck to the rear bumper
11:55 AM roycroft: the winch draws 460a at full pulling power
11:56 AM roycroft: 4/0 wire is rated to 300a
11:56 AM roycroft: and is already pretty large
11:56 AM roycroft: most winch manufactures ship with 2ga or 4ga wire for their high amperage winches
11:57 AM roycroft: i'm assuming that because it's intermittent duty that i don't need the super heavy wires that are needed for continuous duty
11:57 AM roycroft: i would like to use 2/0 wire for that long run
11:57 AM roycroft: for something with at 5% duty cycle at full aperage does that sound reasonable to you?
11:58 AM roycroft: this is a 12,000lb winch, and most of my pulls will be <1,000lbs
11:58 AM roycroft: so i could probably use 8ga or 10ga and be fine most of the time
11:58 AM JT-Cave: what happens is the wire will get warm then hot so the longer you run it with too small wire the hotter it gets
11:58 AM roycroft: right
11:58 AM roycroft: and at a 5% duty cycle that's not likely to be much of a problem
11:58 AM JT-Cave: we used to be told for temp lights keep putting them on till the breaker trips then take one off
11:59 AM roycroft: the only other issue would be voltage drop
11:59 AM roycroft: but 20' is not all that long a run
11:59 AM JT-Cave: yup and if you have a meter you can see what the actual drop is but for such a short distance I doubt you will see any voltage drop
12:00 PM roycroft: so it's probably not much of an issue
12:00 PM roycroft: i'm looking at glorified jumper cables, and 2/0 cables are rated at 1400a for jump starting
12:00 PM JT-Cave: do you have any 12 gauge laying around?
12:00 PM roycroft: yes
12:00 PM JT-Cave: test with that
12:00 PM roycroft: it will be hard to test under load
12:01 PM roycroft: because i don't have anything that weights 12,000lbs to pull on :)
12:01 PM JT-Cave: pull your truck up a tree :)
12:01 PM roguish[m]: too big is better than too small
12:01 PM roycroft: not always, roguish
12:01 PM Tom_L: use a big tree...
12:01 PM JT-Cave: lol
12:01 PM roycroft: not when "too big" is really big
12:01 PM Tom_L: or you may need a saw too
12:01 PM * JT-Cave takes a nap
12:01 PM roycroft: wrestling 4/0 wire can be a lot of work
12:01 PM roycroft: and it is very expensive
12:02 PM Tom_L: or 2x half that size
12:02 PM roycroft: and finding a safe place to tuck it underneath the truck an be a challenge
12:02 PM Tom_L: parallel them
12:02 PM roycroft: that is a possibility, but terminating the wires gets to be messier
12:02 PM roycroft: as i said, most of my pulls will be 1000lbs or less
12:03 PM roycroft: i got the big winch so that i can extend the duty cycle on light pulls
12:03 PM roycroft: but maybe my truck will get stuck some day, and i'll have to do a 7000 pull to get it unstuck
12:03 PM JT-Cave: Tom_L, pushed a couple of fixes
12:03 PM roycroft: i want to be prepared for that
12:03 PM Tom_L: ok
12:03 PM Tom_L: what should i look for?
12:03 PM roycroft: thanks, enjoy your nap
12:04 PM JT-Cave: it should open a mesact config ok and not delete the files and a non mesact it should give you a better warning about what's fixing to happen
12:04 PM roycroft: i need to go out and see how the batteries are wired before i deal with the winch wiring
12:04 PM travis_f[TEST]: mesact 1.1.2, mesaflash 3.4.6, does this version of mesact work yet? seems buggy...
12:04 PM roycroft: i don't know if they're isolated or not
12:05 PM JT-Cave: been working for a long time just keeps getting better
12:05 PM Tom_L: travis_f[TEST], it should work on a mesact built config
12:05 PM Tom_L: he just likes to break it
12:05 PM JT-Cave: buggy is very hard to diagnose
12:05 PM Tom_L: gives him something to dream about during naptime
12:06 PM travis_f[TEST]: i have a 7i80HD-25, but the firmware selections are for the -16 and it will not pass a IP check, even though i can ping it
12:06 PM Tom_L: he doesn't have all the card info filled in for all those yet
12:06 PM travis_f[TEST]: oh, ok. fair enough :-)
12:07 PM Tom_L: gawd!
12:07 PM roycroft: i remember from my telecom days wrestling with huge wires at the central offices
12:08 PM roycroft: the voltage drop on dc wires is a lot more than ac wires, and the telcos did not want people collocating in their central offices
12:08 PM roycroft: one of their strategies to "discourage" collcation was to build the power plant for the collocators far far away from their racks
12:08 PM Tom_L: travis_f[TEST], you will never use all that -25 btw. the -16 is plenty big enough
12:08 PM roycroft: requiring ginormous power cables to the racks, which the collactors had to pay for
12:09 PM travis_f[TEST]: dang wifi... i am back, if i missed anything :-)
12:09 PM roycroft: the telco would build its own battery distribution racks right next to their racks, and were able to use smaller cables for their own stuff
12:10 PM Tom_L: travis_f[TEST], we were just talking about you
12:11 PM travis_f[TEST]: i bet :-)
12:12 PM travis_f[TEST]: all bad i hope ;-)
12:14 PM travis_f[TEST]: "Tom_L: travis_f[TEST], you will never use all that -25 btw. the -16 is plenty big enough" the -16 wasn't available at the time
12:14 PM Tom_L: ahh
12:15 PM travis_f[TEST]: it is my backup for my current machine, in case the card i have (-16) gets killed, i have a pre-loaded spare to plug in. besides, i use it for testing various things
12:16 PM Tom_L: you do know you have to use a different bit file for it if it's not the same as the -16
12:16 PM travis_f[TEST]: i know that, it is loaded with the same, but for the -25
12:16 PM Tom_L: ok, just checking
12:26 PM sensille: solarwind: my 6040 is finally running on the closed loop steppers you recommended. 6000mm/min for jogging is no problem at all even at lowest current setting :-)
12:26 PM sensille: and it isn't as scary as i thought it would be
12:27 PM Tom_L: 230 ipm is about what my steppers rapid
12:27 PM Tom_L: nice rate for a small mill
12:29 PM sensille: could probably go faster, but there's not much to gain anymore
12:29 PM sensille: and the hostmot2-port works well so far, too
12:29 PM Tom_L: commercial ones go 5-6x that
12:30 PM * sensille tries to go faster
12:30 PM Tom_L: that'll make ya pucker
12:31 PM roguish[m]: toooo fast just means more mistakes faster......
12:31 PM Tom_L: time is money for them
12:32 PM sensille: now i want to know
12:32 PM Tom_L: and once it's proven it's just rinse and repeat..
12:33 PM sensille: uh? joint0 following error? there is no feedback from the stepper
12:33 PM Tom_L: i don't run mine as hard as i could.. not in that big a hurry
12:33 PM Tom_L: you reached that point
12:33 PM sensille: but where?
12:33 PM sensille: not mechanics/electronics
12:33 PM sensille: some config
12:33 PM Tom_L: umm.. no in the config
12:34 PM Tom_L: one of the velocities
12:35 PM sensille: stepgen_maxvel
12:35 PM Tom_L: maybe STEPGEN_MAXACCEL
12:35 PM Tom_L: or maxvel
12:35 PM Tom_L: i set STEPGEN_MAXVEL = 0
12:36 PM sensille: maxvel is too big for current step timings
12:36 PM Tom_L: try 0 and see what that does
12:37 PM sensille: i also had to reduce the steplen from 2000 to 1500
12:37 PM Tom_L: Older configuration files have a velocity limit for the step generator as well. If specified, it should also be 1% to 10% larger than the joint MAX_VELOCITY.
12:38 PM sensille: ok, now the stepper driver went into alarm. time to raise the current :)
12:39 PM sensille: i always forget how it works, the stepper is rated for 5A. is that RMS?
12:39 PM sensille: 4A RMS is probably good then
12:40 PM Tom_L: JT-Cave, #62
12:44 PM sensille: now it's chugging along happily at 12000mm/min
12:46 PM travis-farmer: Hmmm... my big machine can only go 210 ipm... not that it is a race, but i am a little jealous ;-)
12:46 PM sensille: it's stupid :)
12:49 PM sensille: it's a bit scary to go full speed towards the limits
12:49 PM sensille: but it works fine
12:49 PM JT-Shop: the 7i92T broke loading firmware for the 7i80 temporarily
12:50 PM travis-farmer: i have accelleration down on my machine, so it slows down before the limits
12:50 PM * JT-Shop tosses a chuck of wood on the fire
12:50 PM sensille: now accel is a bit defensive with 1000
12:50 PM JT-Shop: Tom_L, I do have a 7i80hd-16 to test with
12:51 PM Tom_L: i thought you did
12:52 PM sensille: nice, i might leave it this way, can get used to it quickly :)
12:57 PM JT-Shop2: I put it back in inventory and thought I sold it but's it's still here so I took it back out of inventory
12:57 PM Tom_L: heh
12:58 PM Tom_L: i put my custom bitfile up if you want to add it then i can test more things i think
12:58 PM Tom_L: .. i thought i did..
01:00 PM Tom_L: i'll upload it in a bit.. in winders atm
01:00 PM JT-Shop2: ok
01:01 PM JT-Shop2: I was just thinking about being able to load any bit file using the file selector
01:02 PM Tom_L: the user can always test to see how it's configured
01:14 PM * travis-farmer tries to decide if it is better to brave the 21F temps and work on his machine.... or to take a nap... ;-)
01:15 PM Tom_L: go for it
01:16 PM travis-farmer: go for it, machine, or go for it, nap ?
01:17 PM JT-Cave: 7i80 firmware tools fixed
01:17 PM roguish[m]: JT-Cave: should i test the 7i80 ?
01:17 PM Tom_L: ok, i'll check once i get caught up here
01:17 PM roguish[m]: got one
01:17 PM JT-Cave: I've had my nap so my opinion is biased
01:17 PM Tom_L: roguish[m], yes!!
01:18 PM JT-Cave: I just tested on my 7i80
01:18 PM JT-Cave: roguish[m], yes
01:19 PM roguish[m]: i'll try it out in a bit.. right now, working on my spindle and vfd
01:23 PM Tom_L: ok. where was i...
01:24 PM markgonz: hello, I am reading about the power supply for the 7i96s, it says it needs 5v in the manual however can't find anything about amps
01:24 PM Tom_L: not that much
01:24 PM Tom_L: depends how much io load you have on it also
01:25 PM JT-Shop2: I test with usb 5v but as you add encoders it's a bit much for a usb 5v
01:26 PM markgonz: I saw someone using a meanwell MDR 60 5, 10A
01:26 PM Tom_L: a bit excessive
01:27 PM markgonz: OK good to know
01:27 PM Tom_L: any small smps should work
01:27 PM Tom_L: used to get them for a couple bucks from china
01:28 PM JT-Shop2: https://www.automationdirect.com/adc/shopping/catalog/power_products_(electrical)/dc_power_supplies/enclosed_chassis_mount/pss0524-100
01:28 PM JT-Shop2: that will work for both 5v and 24v
01:28 PM markgonz: ok so then I could get a 5v 3A plug in the wall type
01:28 PM Tom_L: JT-Shop2, what was i testing?
01:28 PM Tom_L: 7i80 configs..
01:29 PM JT-Shop2: I forgot I was napping
01:29 PM Tom_L: oh and ul the custom bitfile
01:30 PM markgonz: Thanks JT
01:30 PM JT-Shop2: yw
01:31 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.2/Bitfiles/7i80/7i80_A_axis_bitfile/
01:32 PM Tom_L: it should have been there for safe keeping anyway
01:32 PM JT-Shop2: ok
01:33 PM Tom_L: you make any changes since adding the 2 debs?
01:33 PM JT-Shop2: fixed the 7i80 firmware
01:33 PM Tom_L: ok
01:36 PM Tom_L: where do you store the bit files for them?
01:36 PM JT-Shop2: in /src/firmware
01:37 PM Tom_L: added mine
01:37 PM JT-Shop2: ok
01:38 PM Tom_L: it only looks for a prefix of 7i80hd-16_
01:38 PM Tom_L: it only looks for a prefix of 7i80hd_16_
01:39 PM JT-Shop2: mesact should load any bit file in the directory for that board
01:40 PM Tom_L: it didn't see mine starting with SVST_2...
01:40 PM JT-Shop2: let me go look
01:40 PM Tom_L: i'm double checking too
01:40 PM JT-Shop2: k
01:41 PM Tom_L: appears it doesn't recheck the directory for recent additions
01:41 PM Tom_L: i renamed it 7i80hd_16_xxx and still not there
01:44 PM -!- #linuxcnc mode set to +v by ChanServ
01:45 PM JT-Cave: I see it when I run mesact
01:45 PM Tom_dev: SVST2_4_7I47S_MILL_A_72.bit or 7i80hd_16_SVST2_4_7I47S_MILL_A_72.bit aren't there
01:45 PM Tom_dev: upper case?
01:45 PM JT-Cave: if you change cards then change back then the directory is reloaded
01:46 PM Tom_dev: i put it in /home/tom/mesact/mesact/src/firmware/7i80hd16/
01:46 PM JT-Cave: I just copied your files, started measct and selected 7i80hd-16 and it's at the bottom of the list
01:46 PM JT-Cave: SVST2_4_7I47S_MILL_A_72.bit
01:47 PM Tom_dev: not here
01:47 PM * Tom_dev rebuilds the tool
01:47 PM JT-Cave: are you running in a terminal from the repo?
01:47 PM Tom_dev: no, from the menu
01:48 PM JT-Cave: the installed files are in src/firmware/7i80hd16/*.* usr/lib/libmesact/7i80hd16
01:48 PM JT-Cave: then you have to put them in usr/lib/libmesact/7i80hd16
01:49 PM JT-Cave: this is the debian files line src/firmware/7i80hd16/*.* usr/lib/libmesact/7i80hd16 so from to during the install
01:50 PM * JT-Cave goes back to the shop
01:50 PM Tom_dev: so they go in usr
01:50 PM Tom_dev: not home/tom
01:52 PM * roycroft would put third-party software in /usr/local, not in /usr
01:53 PM JT-Shop2: to test local changes open a terminal in mesact/src and run with ./mesact
01:53 PM JT-Shop2: me is a rebel...
01:53 PM * JT-Shop2 even
01:54 PM roycroft: anyway, i decided to get the 2/0 30' jumper cables and use that for the winch for now
01:54 PM roycroft: thinking about crawling underneath my truck to pull wires during the rainy season did not appeal to me
01:54 PM * JT-Shop2 tried to decide if dry white oak is a good material for a segmented bowl
01:54 PM roycroft: i can revisit permanent wiring next spring
01:55 PM roycroft: dry wood is usually not great for turning
01:55 PM JT-Shop2: that I know but when you have dry wood you use it
01:55 PM roycroft: and white oak can be a bit grabby, with the stark difference in hardness between the pith wood and the annual rings
01:55 PM travis_f[SHOP]: ok, i have my scope connected to my USB to RS485 thing, while it is connected to my VFD. using the arduino IDE serial monitor, i can send data, and see it on the scope. but LCNC sends no data at any time... so my VFD may be fine. just something in the config somewhere, maybe
01:55 PM JT-Shop2: it gets pretty warm as you turn but other than that I've not noticed anything else
01:56 PM roycroft: it's like yellow pine in that respect
01:56 PM roycroft: or douglas fir
01:56 PM Tom_dev: ok they're there
01:56 PM roycroft: cherry or walnut or even red oak would be better
01:56 PM JT-Shop2: the last bowls were with red oak
01:57 PM roycroft: basically, any wood that tends to get wavy as you sand it is going to be grabby when you turn it
01:57 PM roycroft: all that said, white oak is a beautiful wood
01:57 PM roycroft: so it may be worth the effort
01:58 PM JT-Shop2: I have very little black walnut so I use it carefully
01:58 PM Tom_dev: hard to come by in these parts..
01:58 PM JT-Shop2: I really think the contrast between the white oak and black walnut will be nice
01:58 PM Tom_dev: i had a little but very little
01:59 PM Tom_dev: made a checker board in HS with that and birch iirc
01:59 PM roycroft: yes, that is a good combo
02:00 PM JT-Shop2: I have one chunk of black walnut 2.25 x 4.5 x 30 and a bunch of smaller bits I got out of the slab
02:00 PM Tom_L: readhmid works on the 7i80hd16
02:00 PM JT-Shop2: Yippie
02:00 PM Tom_L: i don't have an old version of mesaflash to test on
02:01 PM JT-Shop2: 7i92t really tossed a monkey wrench in the works
02:01 PM Tom_L: it would have been a regular 7i80
02:01 PM Tom_L: you might ask when he changed it
02:01 PM miss0r5: I find myself in a situation here where I need to figure out the height of the prism way in refrence to the flat way of a small lathe. What is the accepted way to measure this?
02:02 PM travis_f[SHOP]: nope, nothing different in my configs from when it worked. did something change in hy_vfd that could be my issue? cause i am getting no data output from LCNC through the HY-VFD to the serial device
02:03 PM roycroft: maybe mount a dial indicator on the carriage, indicate the slideways, and then use the cross-feed to move it to indicate the top of the prism?
02:04 PM Tom_L: lemme see if the rpi has an old version
02:04 PM miss0r5: roycroft: What I failed to mention is that the prism has a flat on top.
02:04 PM roycroft: right, they usually do
02:04 PM roycroft: and that's what you can indicate on
02:05 PM miss0r5: and I need to figure out where the theoretical point of the prism triangle is within 0.01mm or better
02:05 PM roycroft: index to the slideway and indicate on the flat on top of the prism
02:05 PM Tom_L: i can tes 3.4.3 on it to see
02:06 PM JT-Shop2: to see?
02:06 PM miss0r5: I can measure the height of the flat in refrence to the flat way. But taking a proper measurement of the width of the flat is not easy, as it also has some rounded edges ect
02:06 PM Tom_L: whether it is 7i80 or 7i80hd-16
02:06 PM JT-Shop2: ah ok
02:06 PM roycroft: so what you need to do is measure the angle of the prism
02:07 PM miss0r5: the included angle is 90degrees
02:07 PM miss0r5: what I was considering was to make a pac-man of a known size
02:07 PM Tom_L: they need rebuilt anyway
02:07 PM miss0r5: and use that as a refrence. But that seems like alot of work if any of you guys had a better idea :)
02:09 PM Tom_L: miss0r5, measure and draw in cad. it will tell you anything you want to know about it
02:10 PM miss0r5: Tom_L: That is the issue. I could use calibers to get a good gestimate, but it will not be better than that
02:10 PM travis_f[SHOP]: well.... apparently i am invisible, so i am going back in to the heat of the house.... :-(
02:10 PM Tom_L: draw the base, angle and measure the height
02:11 PM miss0r5: Tom_L: I think the issue with that approach is getting 0.01mm or better precision
02:19 PM travis-farmer: sure am glad i braved the cold to work on my machine... :-(
02:21 PM roycroft: the sun is shining here, for now
02:22 PM roycroft: i think i'll go out and try to gather up some leaves for the leaf sucker-upper
02:22 PM roycroft: it was supposed to rain all day, but i guess now
02:22 PM roycroft: not
02:22 PM roycroft: well, if i go out and start working it will amost be sure to start raining
02:24 PM * JT-Shop2 decides to ponder the bowl while packing orders
02:25 PM * travis-farmer decides to sell what is left of his machine
02:49 PM pere: <URL: https://yewtu.be/watch?v=SVY6vKu9tFM > is interesting. Fadal VMC20 with LinuxCNC.
02:51 PM Tom_L: JT-Shop2, #63
02:55 PM JT-Shop: ok
03:00 PM Tom_L: JT-Shop, mesaflash version 3.4.3 was also 7i80hd-16
03:00 PM Tom_L: that may have been the one it was changed in
03:01 PM Tom_L: i know the mill has an older version but i don't have a 7i80 on it
03:03 PM Tom_L: mmm i can't test it there anyway, it's RTAI
03:07 PM JT-Shop: if you have a clone of mesaflash you could grep to find the file then view the history of that file
03:07 PM Tom_L: i have an old one but not sure what version. trying to build it
03:09 PM JT-Shop: anyio.c and eth_boards.c are the only files with 7i80 in it
03:09 PM Tom_L: might be easiest to ask pcw---home
03:10 PM JT-Shop: also I cloned mesaflash a few years ago from migtes repo and then added it to linuxcnc and we lost the history
03:10 PM Tom_L: where was the mesaflash version shown in the old ones?
03:10 PM Tom_L: i didn't see it in mesaflash.c
03:11 PM Tom_L: this one has 7i80 as the board name
03:11 PM Tom_L: but also has 7i80db-16
03:11 PM Tom_L: in eth_boards.c
03:12 PM Tom_L: anyio.c has 7i80
03:13 PM Tom_L: this was 3.2.0~pre
03:13 PM Tom_L: looks like it was 7i80hd-16 then
03:14 PM Tom_L: i doubt i have anything older saved
03:21 PM Tom_L: all i can find are 3.2.0~pre, 3.4.3 and 3.4.6
03:28 PM roguish[m]: Tom_L: what kernel are you guys using for your bookworm systems?
03:29 PM Tom_L: phone then i'll check
03:30 PM Tom_dev: Linux bookworm 6.0.0-3-rt-amd64 #1 SMP PREEMPT_RT Debian 6.0.7-1 (2022-11-05) x86_64 GNU/Linux
03:31 PM JT-Shop: the version may not be in earlier mesaflash
03:32 PM JT-Shop: it's amazing how some folks don't understand how the IRC works... someone may be at the keyboard watching but not know the answer to an uncommon question
03:32 PM * JT-Shop wanders to the other shop to ponder bowls
03:33 PM miss0r5: okay. I machined a quite precise pacman. That allowed me to get the measurement within 0.01mm
03:34 PM XXCoder: the packman game charactor?
03:34 PM miss0r5: yeah
03:34 PM XXCoder: lol ok :)
03:35 PM miss0r5: that is basically what it looks like
03:35 PM miss0r5: I had to pick up the theoretical point of the prism top in refrence to the flat on the lathe
03:38 PM Tom_L: found a 3.3.0~pre version that has 7i80hd-16
03:44 PM Tom_L: JT-Shop, i think it goes far enough back i'd use 7i80hd-16
03:45 PM Tom_L: anybody starting out won't find those versions now anyway
03:47 PM JT-Shop: alright you solved that now where's my book on segmented bowls?
03:48 PM XXCoder: its behind you jt
03:49 PM Tom_L: under all that dust
03:49 PM Tom_L: i found a variety of versions though :)
03:51 PM JT-Shop2: the book should be in here somewhere...
03:54 PM travis_farmer: "it's amazing how some folks don't understand how the IRC works" sorry, it is just extremely frustrating when a question is asked, and exactly nobody even acknowledges the question. kind of gives the impression that i am unworthy of asking such a question. :-(
03:55 PM JT-Shop2: usually folks only reply if they have some information
03:57 PM travis_farmer: sorry, that is not how my mind works
03:59 PM travis_farmer: dang wifi keeps cutting out... :-(
04:04 PM * travis_farmer looks through hy_vfd source code, to see if there are any answers...
04:04 PM JT-Shop2: have you searched the forum?
04:05 PM travis_farmer: will do that next
04:05 PM JT-Shop2: a lot of info there
04:05 PM Tom_L: yeah i never did modbus on vfd
04:05 PM Tom_L: but i'll be glad to send you on a wild goose chase if you like..
04:06 PM Tom_L: mine has the plug for it but no docs and doesn't appear to have any firmware setings for it
04:08 PM travis_farmer: i guess the HY VFDs are a different animal from regular modbus... i just don't understand why it is not transfering data... (searching forum...)
04:10 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/PDF/BLDC/
04:10 PM Tom_L: there's the docs i found for mine
04:10 PM Tom_L: google translate did fair
04:10 PM JT-Shop2: https://www.ebay.com/itm/255855193841?hash=item3b92286ef1:g:QPEAAOSwYLBjh9Q6&amdata=enc%3AAQAHAAAAoAPc1plGwVWkKbrbyJ7Bj4SIw29afkfaFkfDixtn1PX1sVZYD3Up5RobzXnQ3wa1u4R9D6hCleY6%2F%2BEw7SRFtnI6E6dic1YqiU0nB6ZdhKUX34Eur8T46t6%2FpwEp48yLRL1aNVaP2VAWE9U8jabr3fAbTHU65jJjGrbLHuYi0Jtiem%2F1Dr219X8D7VV8J7fqDYOCDI%2FY%2FYhF2CHhXVinulc%3D%7Ctkp%3ABk9SR4yL2rOgYQ
04:10 PM JT-Shop2: project car
04:10 PM travis_farmer: Hmmm, there is a "--debug" option for hy_vfd. mental note...
04:11 PM Tom_L: JT-Shop2, you need another project
04:11 PM Plaid: You can help me with my projects :P
04:12 PM JT-Shop2: LOL
04:12 PM JT-Shop2: Plaid, I did help you
04:12 PM Plaid: I mean. Help me more :P
04:12 PM Tom_L: we're just not going to come over and do it for you !
04:13 PM Plaid: Like... That's what I want JT to do :P
04:13 PM Tom_L: read
04:13 PM Tom_L: and read more
04:13 PM Plaid: Getting this CNC working is a side-project to my main project of building a 4 seat airplane :P
04:14 PM Tom_L: i did figure out why i couldn't connect to the 7i80 on buster
04:14 PM Tom_L: duh. static ip: 10.10.10.10/24
04:14 PM JT-Shop2: on the pc?
04:14 PM Tom_L: whadday suppose the board was set for?
04:14 PM Tom_L: he
04:14 PM Tom_L: h
04:14 PM JT-Shop2: same
04:15 PM Tom_L: too many ssd sd configs
04:15 PM * JT-Shop2 stops cruzing fleabay for a c6
04:16 PM Tom_L: ok that's fixed
04:17 PM JT-Shop2: now find my book on segmented bowls
04:17 PM XXCoder: $10 a hour plus transit costs for me to go to your place to look for that book
04:18 PM Tom_L: kc is spanking denver today
04:18 PM JT-Shop2: Pearl will be happy
04:18 PM JT-Shop2: she is a kc fan
04:18 PM unterhaus: sort of surprised that a virtual gpu from nvidia costs money
04:18 PM Tom_L: interception for a score just now
04:19 PM Tom_L: 27 0
04:19 PM JT-Shop2: damn
04:19 PM * JT-Shop2 wonders if the book is downstairs...
04:20 PM * Tom_L wonders if JT-Shop mistook it for chicken little
04:20 PM JT-Shop2: the story would have been disappointing to the hens
04:23 PM Tom_L: denver just intercepted..
04:24 PM * Tom_L goes for a nap
04:29 PM travis_farmer: i think i found my issue... it is a clear ID-ten-T error... i forgot to set the VFD to enabled in my HAL file...
04:29 PM * travis_farmer hangs his head in shame
04:29 PM Plaid: Stupid ID-ten-Ts
04:29 PM Tom_L: :/
04:30 PM * JT-Shop2 has no clue what travis_farmer is speaking
04:31 PM Plaid: Using halscope, is there a way to trigger on sending gcode from the UI? Or motion starting?
04:32 PM JT-Shop2: prob motion starting
04:32 PM travis_farmer: the solution to my USB to RS485 device communicating, should be simply adding "setp vfd.enable 1" in my HAL file, so the module is enabled. i will try it tomorrow.
04:32 PM travis_farmer: i bet it wasn't sending data, because it wasn't enabled to
04:32 PM JT-Shop2: motion.current-vel maybe
04:34 PM * JT-Shop2 listens to Lunatic Fringe and watches chicken tv
04:34 PM Plaid: oooh, hadn't thought about motion.... motion.in-position
04:35 PM Plaid: Oh, that looks great on the scope
04:45 PM * travis_farmer time to go to the store, and then bed. at least i can rest easy, knowing where i went wrong. :-)
04:48 PM JT-Shop2: glad you figured it out
04:55 PM roycroft: well, i have about 2/3 of my leaf pile out in the street
04:55 PM * roycroft is taking a brief break
04:55 PM roycroft: my leaf pile so far is, i think, bigger than all my neighbors' combined
04:56 PM roycroft: probably because i have three large black oak trees on my property, and my neighbors mostly have conifers and small fruit trees
05:09 PM Tom_L: do you leave them there?
05:09 PM pere: First draft documenting how to run and write tests, <URL: https://github.com/LinuxCNC/linuxcnc/pull/2203 >
05:10 PM Tom_L: you do that here and you'll start a feud
05:12 PM saquzi: Hi, still having same issue with my 7i97+8i20+fanuc servo, not getting it to move etc, just got back from vacation... I see that i dont have any pwmgens or pwm3gens in my hal, should 8i20 type of amplifier needing those signals?
05:12 PM saquzi: loadrt hm2_eth board_ip="10.10.10.10" config="num_encoders=6 n0 num_stepgens=0 sserial_port_0=000xxx"
05:14 PM saquzi: or is it used only with some other servo amps that does not use the rs422/485 to communication with the fpga
05:21 PM pcw---home: No, the 8I20 only needs a sserial port, a feedback source (encoder) and the bldc component
05:45 PM Plaid: To tune by closed loop servos on my 4' by 8' router, I've be going back and forth between two points on the same axis going back and forth between two points about 2 inches apart, and trying to find values that minimize the pid.1.error. Seem like a reasoonable approach to doing it?
05:46 PM Plaid: Right now it's tuned to within .05mm using that
05:52 PM saquzi: Or.. something important missing that is telling 8i20 the position and amount of current given in every phase
06:13 PM pcw---home: The 8I20 typically needs current set (via a PID position feedback loop) and angle set (via the bldc component)
07:29 PM Plaid: So I can convert my servo amp to velocity mode instad of current mode. Would it be better for me to do that?
07:29 PM Plaid: It's kind of an annoying conversion for me to do, but it's doable
07:56 PM Plaid: I just kind of realized that if I'm feeding in torque values... I'll be way undershooting torque when I'm cutting vs doing test runs.
08:04 PM CaptHindsight[m]: https://vivaldi.com/ going to add this browser instead of Firefox to the Gentoo installer
08:05 PM CaptHindsight[m]: takes up only 50MB vs >200MB
08:10 PM roycroft: i was just listening to the red priest earlier today
08:12 PM XXCoder: seems filezilla will be added
08:13 PM CaptHindsight[m]: https://forum.linuxcnc.org/38-general-linuxcnc-questions/47642-gentoo-image-which-applications-are-in-and-which-are-out any ideas for adding or removing apps?
08:15 PM roycroft: is there a youtube ad blocker plugin for vivaldi that actually works well?
08:15 PM XXCoder: wonder if it also has noscript
08:16 PM CaptHindsight[m]: roycroft: good question
08:17 PM CaptHindsight[m]: well it has it built in
08:17 PM CaptHindsight[m]: https://vivaldi.com/#browser-features
08:18 PM CaptHindsight[m]: https://vivaldi.com/features/ad-blocker/
08:18 PM CaptHindsight[m]: https://vivaldi.com/features/privacy-security/
08:19 PM CaptHindsight[m]: Vivaldi has an insane amount of customization available by default.
08:21 PM CaptHindsight[m]: Also includes Xarchiver on the installer
08:22 PM CaptHindsight[m]: XXCoder: Chrome extensions work in Vivaldi
08:22 PM XXCoder: cool
08:22 PM CaptHindsight[m]: so you can install noscript
08:22 PM CaptHindsight[m]: https://help.vivaldi.com/desktop/appearance-customization/extensions/
08:31 PM solarwind: sensille nice, glad to hear it worked out
08:31 PM solarwind: CaptHindsight[m] what do I do with my failed prints? Is it worth making a filament extruder to recycle them?
08:31 PM solarwind: Or should I just cast them into plaster moulds?
08:32 PM CaptHindsight[m]: how much scrap do you have?
08:33 PM CaptHindsight[m]: 100's of KG's?
08:34 PM CaptHindsight[m]: if you make an extruder make it so that you can make custom blends with your own fillers and colors
08:34 PM CaptHindsight[m]: I had a big one, well ok size ~25hp
08:36 PM CaptHindsight[m]: solarwind: ^^
08:44 PM solarwind: wow
08:44 PM solarwind: I have... less than 2kg
08:44 PM solarwind: But because it's so reusable, feels like a waste
08:45 PM solarwind: Especially since I'm going to be building a Voron 2.4 or CroXY type printer and lots of experiments printing useless things to tune it properly
08:46 PM solarwind: Plaster moulds for project boxes/cases sounds like a good idea for the small amount of PLA and PETG that I have
08:53 PM CaptHindsight[m]: no resin printer yet?
09:01 PM CaptHindsight[m]: https://help.vivaldi.com/desktop/privacy/is-vivaldi-open-source/
09:04 PM solarwind: CaptHindsight[m] that's on the to buy list
09:04 PM solarwind: I'll get a decent DLP one
09:14 PM CloudEvil: Most plastics are not really heat-upable to temperatures at which they will easily flow into molds.
09:14 PM CloudEvil: Especially not in air
09:14 PM XXCoder: would need plastic injection since thats pressurized
09:20 PM CaptHindsight[m]: it's always some license problem
09:21 PM solarwind: PLA seems to flow really well. I'm thinking I could just make a hand-held extruder with a big 2mm bore to fill up molds
09:22 PM solarwind: PETG also seems to flow quite well. They both sag/deform from gravity if you set the print temperature a bit high
09:22 PM solarwind: For simple moulds, that's all I need
09:22 PM solarwind: I just ran a test in my toaster and it filled up a small cup quite nicely
09:23 PM solarwind: None of this has to be perfect, it's just a way to avoid throwing out failed prints over time
09:43 PM CaptHindsight[m]: sure why not
09:45 PM CaptHindsight[m]: how about a glue gun that is CNC?
09:46 PM CaptHindsight[m]: https://hackaday.com/2012/06/05/tearing-apart-a-hot-glue-gun-for-a-3d-printer/ this could kick off a whole new industry :)
09:47 PM solarwind: Or a TIG welder fitted to a 3D printer and controlled by LinuxCNC: https://www.youtube.com/watch?v=E9tVj9qJ_ns
09:47 PM solarwind: additive TIG :)
09:47 PM CaptHindsight[m]: CNC metal gun
09:48 PM solarwind: the challenge there is making all the parts heat and UV resistant
09:48 PM CaptHindsight[m]: cringe
09:50 PM CaptHindsight[m]: how about working with hot parts that you can't touch? well except at very small points for s short time
09:57 PM Plaid: Watching the additive TIG video, I was thinking... After a few minutes of welding in a closed space, you'll use up all the oxygen, so even if the argon does leak out, any O2 will quickly get consumed
09:57 PM CaptHindsight[m]: roycroft: https://www.youtube.com/watch?v=0bsEEUvXlD4
09:58 PM XXCoder: eh no gloves with epoxy
10:02 PM CaptHindsight[m]: https://www.youtube.com/watch?v=DTydaGpUC0E rapid metal printing
10:03 PM CaptHindsight[m]: nozzle close up https://youtu.be/th1rlVkDII0?t=67
10:06 PM CaptHindsight[m]: you can print sand molds faster than they can cold spray
10:15 PM CaptHindsight[m]: With a deposition rate of 100 g/min, a maximum part build size of ø 1000 x 700mm and a maximum part weight of 40 kg,
10:16 PM CaptHindsight[m]: "WarpSPEE3D is able to produce industrial components in a matter of hours that would typically take 6-12 months using traditional casting methods." but also only in hours using modern 3d printed casting methods
10:17 PM CaptHindsight[m]: and you can make sand molds for parts that weigh 100's or 1K's of kilograms
10:27 PM roycroft: capthindsight: that thing is hideous, but at least it's not a river table
10:32 PM * roycroft thinks taste has gone the same way as civility these days
10:46 PM Plaid: Any suggestions on how to tune the pid for a torque based setup?
10:51 PM XXCoder: any river crap table is better than those bunch that shows how to use high voltage to make "arty" table. very deadly
10:54 PM XXCoder: roycroft: what sucks is that after ann release video warning about those very dangerous craft, youtube didnt remove those videos.
10:54 PM XXCoder: they removed ann warning video. its back since then but yeah
10:55 PM XXCoder: https://youtu.be/wzosDKcXQ0I
10:59 PM roycroft: oh, yeah, those "fractal
10:59 PM XXCoder: yeah.
10:59 PM roycroft: " burned wood videos are dangerous
10:59 PM roycroft: it doesn't have to be dangerous, but it easily can be
11:00 PM roycroft: if i wanted to do that i'm confident that i would be able to do it very safely
11:00 PM roycroft: but i don't, so it doesn't matter :)
11:01 PM XXCoder: yeah. what I would do is have good distance between me and electric probes and im standing on thick rubber mats and wearing rubber gloves
11:01 PM Plaid: Just hold on to the exposed end of a high voltage transformer. What could go wrong
11:01 PM XXCoder: design it so I can lever it up and down at endpoint near the wood surface to be burnt
11:02 PM XXCoder: that way I cannot acciently electrify myself and id have warning fence around area
11:02 PM XXCoder: frankly I dont want to do it even if I can safely do it
11:05 PM Plaid: I wish I had a script that'd do gradient descent to do my pid tuning
11:24 PM roycroft: some day i might find it interesting enough to experiment with it
11:24 PM roycroft: but it's pretty low on my list of interests
11:24 PM roycroft: not as low as making a river table though :)
11:24 PM XXCoder: :)
11:35 PM roycroft: my logo designer just sent me some new varients on the design she's working on for me
11:36 PM roycroft: i'm pretty pleased, and i think i'll have a good logo by the end of the year
11:38 PM roycroft: it's nothing at all like what i was trying to formulate in my mind, but it captures exactly what i want
11:38 PM roycroft: going to a professional is usually a good idea, and in this case it definitely was
11:39 PM XXCoder: nice
