03:47 AM randy: morning
03:52 AM silopolis[m]: morning πŸ™‚
04:14 AM silopolis[m]: Someone to help me understand this please:
04:14 AM silopolis[m]: * *`G49`* - *Cancels Tool Length Compensation*
04:15 AM silopolis[m]: It is OK to program using the same offset already in use. +
04:15 AM silopolis[m]: I don't get that offset comment as there's no parameter for G49 πŸ€”
04:23 AM silopolis[m]: Also, in docs, G43.1 is said to 'replace' current TLO, but given example looks like a additionnal TLO, ie G43.2:... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/e61ff028b5d5d0b25fb1ef7c3c59ed38d30f43dc)

04:24 AM xxcoder8265[m]: id suggest try avoid editing
04:24 AM xxcoder8265[m]: on irc we see every revision lol
04:24 AM silopolis[m]: ouch sorry ! I'll be more careful...
04:25 AM xxcoder8265[m]: no problem lol
04:32 AM Tom_L: morning
04:36 AM Tom_L: silopolis[m], i don't use G43.1 but what i read is that it replaces the offset read from the tool table with a value you enter on that G43.1 line for that axis
04:38 AM Tom_L: silopolis[m], G49 It is OK..... (it will not throw an error if a value is present)
04:39 AM Tom_L: it will probably just ignore it
04:40 AM Tom_L: G49 G49 H1 ... H1 would just be ignored
04:40 AM Tom_L: a good way to find out would be to try it :)
05:00 AM JT-Cave: morning
05:00 AM Tom_L: morning
05:01 AM Tom_L: your utility is awesome...
05:01 AM JT-Cave: thanks
05:01 AM Tom_L: a few things i'm not sure what they're for
05:01 AM Tom_L: PC
05:02 AM Tom_L: should be a big help for noobs
05:02 AM Tom_L: especially since you can reopen it
05:03 AM JT-Cave: you can get info about the cpu and nic and test packet time for the nic
05:03 AM silopolis[m]: <Tom_L> "silopolis, i don't use G43.1 but..." <- I read that too, but the example seems to say that the value is added to the current offset. Like if that example was in fact a G43.2 example
05:04 AM silopolis[m]: <Tom_L> "a good way to find out would..." <- Level of ununderstanding was such that I didn't know what I could test πŸ˜…
05:05 AM Tom_L: G43.1 adds it from the command line, G43.2 adds it from another table offset
05:05 AM Tom_L: that's my interpretation and i'm stickin to it!
05:06 AM silopolis[m]: Not what I read in docs !
05:07 AM Tom_L: http://linuxcnc.org/docs/stable/html/gcode/g-code.html#gcode:g43.1
05:07 AM Tom_L: read the 2 lines
05:07 AM silopolis[m]: G43.2 adds it from tool table OR given value
05:07 AM Tom_L: G43.1 Z xxx G43.2 H xxx
05:07 AM silopolis[m]: Tom_L: I'm asking this because I'm working on docs lol
05:08 AM Tom_L: that's how i read it anyway
05:08 AM silopolis[m]: It is an error if:... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/649754925c2a009f766d166660a71067950caeb4)
05:09 AM Tom_L: that would apply to G43.2
05:09 AM silopolis[m]: yes
05:10 AM Tom_L: but not G43.1
05:10 AM silopolis[m]: so can take value from tool table OR given value
05:10 AM silopolis[m]: and indeed modifies current TLO
05:10 AM Tom_L: depending which command you use yes
05:10 AM Tom_L: 1 or 2
05:12 AM Tom_L: all i use is G43 H xxx by itself
05:12 AM Tom_L: i don't add offsets to that in my programs
05:12 AM Tom_L: aparently someone had a reason to
05:14 AM silopolis[m]: If G43.1 actually replaces TLO then example in doc is wrong
05:14 AM Tom_L: it is additive
05:15 AM Tom_L: i could test it but not right now
06:04 AM * travis_farmer853 uploaded an image: (58KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/cXJQOzGRzBLxWvPDjYMtcdkI/286420046_10159302359589405_735075153408357334_n.jpg >
06:04 AM travis_farmer853: i don't normally share memes in places other than Facebook, but this one caught my funny-bone. for those knowing what Python really refers to πŸ˜‰
06:05 AM XXCoder: hah
06:10 AM silopolis[m]: So, in 2.8, it looks like:
06:10 AM silopolis[m]: * G43.1 takes 'Axes-' *only* as parameters and indeed replaces current TLO
06:10 AM silopolis[m]: * G43.2 takes 'H<tool_number>' *only* as parameter and adds it to current TLO
06:10 AM silopolis[m]: Now to build myself a 2.9 to check if things have changed...
06:55 AM travis_farmer853: so excited... my new internet service (Cable) gets installed today! πŸ™‚ going to be a PITA to get everything setup and migrated, but i am still excited.
07:12 AM travis_farmer853: i am a little concerned about the shipment of my used 3D printer... 4 days, and still no ship notification... i will give them until noon, and then inquire with the seller.
07:16 AM JoseIgnacioRomer: travis_farmer: is that one of those used ender3s?
07:17 AM JoseIgnacioRomer: From ebay
07:17 AM travis_farmer853: yes
07:17 AM JoseIgnacioRomer: That seller does take their sweet friggin time to ship the things
07:17 AM travis_farmer853: Hmmm...
07:22 AM travis_farmer853: just started reading the negative feedback, and now i regret the purchase...
08:47 AM JT-Shop2: can you cancel the order for non shipment
08:48 AM travis_farmer853: i will try...
08:54 AM travis_farmer853: just sent seller a message, will see what turns up from it...
09:13 AM roguish[m]: _discord_731083529441640538[m]: what kinda printer arer you getting?
09:36 AM roycroft: some online sellers are slow to ship
09:37 AM roycroft: 4 days is not all that long
09:37 AM roycroft: also, some don't send shipping confirmations/tracking numbers
09:38 AM * roycroft just loaded the silver/grey filament again - the stuff that broke when he first tried it - and hope it prints well now, after the printer upgrade
09:48 AM * JT-Shop2 does some wax on... wax off on the shiny parts
10:23 AM * travis_farmer853 uploaded an image: (32KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/dbYHgGIerhleloWpqBXheTFS/Screenshot_2022-06-07_at_06-22-24_speedtest_-_Google_Search.png >
10:23 AM travis_farmer853: old internet speed test...

10:23 AM travis_farmer853: new internet speed test πŸ™‚
10:53 AM travis_farmer853: quiet in here today...
10:56 AM Tom_L: JT-Shop2, is that planer 220v?
10:59 AM JT-Shop: yep
10:59 AM * JT-Shop goes inside for lunch minute
10:59 AM Tom_L: i figured it probably had a hefty motor on it
11:05 AM JT-Cave: 3hp
11:57 AM JT-Shop2: foul play they forgot to tap the M5 holes in the dust chute... I actually had a M5 tap
12:03 PM roycroft: as far as screwups go, that's not a bad one
12:07 PM -!- #linuxcnc mode set to +v by ChanServ
12:34 PM * Tom_L finishes up a sammich
12:47 PM * JT-Shop is ready for winter now... used 385 gallons of propane last year
01:09 PM Rowow[m] is now known as Rowow5457[m]
01:09 PM Rowow5457[m]: im confused by the bots and im scared to ask
01:09 PM roycroft: the bot do not bite, the last time i checked
01:10 PM Rowow5457[m]: of course you would defend the bots, you bot
01:10 PM roycroft: i'm not defending them - just conveying my impression of their behavior
01:11 PM roycroft: i personally seriously dislike bots/loggers on irc channels
01:15 PM Rowow5457[m]: it would be nice if the bots had different PFP/role colors
01:15 PM Rowow5457[m]: currently hard to differentiate whos saying what
01:15 PM Rowow5457[m]: maybe im just not used to them
01:26 PM travis_farmer853: the bots are people connected through the IRC and Matrix bridge
01:28 PM XXCoder: yeah
01:28 PM xxcoder8265[m]: hi. lol. im on both ends
01:29 PM travis_farmer: i can be, too, but mostly on Discord ;)
01:29 PM Tom_L: scardiecat
01:30 PM travis_farmer853: LMAO
01:30 PM Tom_L: afik there is one bot that logs the channel for skunkworks's dad
01:30 PM xxcoder8265[m]: im brave enough to be on both irc and discord, but not matrix lol
01:30 PM Tom_L: hi dad!
01:30 PM Tom_L: so Rowow5457[m] did you have a real question?
01:31 PM travis_farmer853: i am mostly on Discord because i have other servers i connect to on it πŸ˜‰
01:31 PM Rowow5457[m]: what do you mean
01:31 PM XXCoder: im on bunch too, but im op here and admin there so gonna be on both lol. I usually use irc for lcnc tho
01:31 PM Tom_L: <Rowow5457[m]....im scared to ask
01:31 PM travis_farmer853: he was just inquiring if you had a question, other than about the bots
01:32 PM Rowow5457[m]: that was my question about the bots
01:32 PM CaptainHindsight: I have a question about the bots but I'm not going to ask it
01:32 PM XXCoder: theres only 3 bots. only one of those is bridge bot
01:32 PM Tom_L: they are soon to take over the planet
01:32 PM travis_farmer853: ok, fair enough.
01:32 PM Tom_L: watch your back
01:32 PM XXCoder: it uses trickery to change nick with who is saying things
01:33 PM travis_farmer853: says a bot πŸ˜‰
01:33 PM Tom_L: we answer linuxcnc questions here, not bot questions
01:33 PM Rowow5457[m]: oh so its from the same discord account? rip
01:33 PM Rowow5457[m]: no way to change the pfp/color?
01:33 PM Tom_L: there are 3 sources here, irc, discord and matrix
01:34 PM Tom_L: sad but true
01:34 PM Tom_L: there are 3 because they can corner you without you knowing it
01:34 PM CaptHindsight[m]: but this is a round channel
01:35 PM travis_farmer853: change the color of the names of the bots? not sure, but you get used to them after a while
01:35 PM Tom_L: CaptHindsight[m], inscribed or circumscribed?
01:35 PM CaptHindsight[m]: I don't really mind the bots
01:35 PM CaptHindsight[m]: more pleasant than some people
01:36 PM Tom_L: i got in trouble on reprap with mine... they didn't want their boss to see what they put there
01:36 PM travis_farmer853: only thing that bugs me is the apos thing... but i can live with it. the bridge is able to bring a wider range of knowledge from other people together.
01:37 PM silopolis[m]: Aaand guess who's bricked his computer!?
01:37 PM Tom_L: yeah it brightens up everyone's day
01:37 PM XXCoder: precisely why I finally gave up and remade discord server so we could have bridges.
01:37 PM silopolis[m]: 😬😭🀬🀬🀬
01:37 PM Tom_L: silopolis[m], right after you backed it ALL up ehh?
01:37 PM travis_farmer853: bricked? not good...
01:37 PM XXCoder: old one was mostly dead even before the move.
01:37 PM XXCoder: hope you have secret stash of backups
01:38 PM silopolis[m]: At that point can't boot nor access setup utility
01:38 PM travis_farmer853: my lcnc computer has no important data on it. the configs are regularly backed up to Github.
01:39 PM XXCoder: bad flash on bios?
01:39 PM XXCoder: wonder if resetting configuration on it would fix
01:40 PM travis_farmer853: hmmm, sounds like a true brick ...
01:41 PM travis_farmer853: any errors?
01:51 PM serp6 is now known as serp
01:53 PM CaptHindsight[m]: HP has some of the worst BIOSes
01:54 PM CaptHindsight[m]: they remove or cripple most features to make support easier
01:54 PM CaptHindsight[m]: yet leave things in like "disable cache"
01:55 PM travis_farmer853: yeah, i had bad history with HP. their old tech support favorite move was to "format and recover"...
01:59 PM CaptHindsight[m]: well then it only costs them your time, not theirs, genius
02:00 PM CaptHindsight[m]: win11 is truly horrible
02:00 PM travis_farmer853: yeah, when i figured that out, i went with either dell, or home-brew
02:01 PM CaptHindsight[m]: it's so bad I just installed it several times on multiple partitions to isolate problems
02:01 PM XXCoder: havent owned a store bought computer tower
02:02 PM XXCoder: alyways built my own. however laptops well its bit harder to do lol
02:02 PM travis_farmer853: sounds like i am glad my laptop is unsupportive of Win11 πŸ˜‰
02:02 PM XXCoder: no windows device here. nor mac
02:04 PM CaptHindsight[m]: but most CAD still relies on it
02:04 PM travis_farmer853: Hmmm, i haven't run into that i guess...
02:04 PM XXCoder: yeah. I use freecad which is no problem
02:06 PM travis_farmer853: Fusion360 here, but i hope to get Vectric V-Carve Pro in the future...
02:08 PM CaptHindsight[m]: I just need to be able to import to FreeCAD
02:09 PM CaptHindsight[m]: I just use it for Path
02:15 PM JT-Shop2: hot fence is repaired back to planer
02:20 PM XXCoder: capt hown well does PATH work in .20?
02:20 PM XXCoder: havent tried it yet
02:41 PM CaptHindsight[m]: XXCoder: I'm working on 5-axis+ for it. Right now it barely handles 3
02:41 PM XXCoder: programming side?
02:42 PM CaptHindsight[m]: yes
02:43 PM CaptHindsight[m]: wish there was another way
02:43 PM CaptHindsight[m]: the next closest is using Rhino
02:43 PM XXCoder: ok. yeah wanted to be clear on what exactly youre doing :D
02:44 PM XXCoder: making gcode vs making program to generate gcode
02:45 PM CaptHindsight[m]: generate g-code and roboth paths
02:45 PM CaptHindsight[m]: s/roboth/robot/
02:46 PM CaptHindsight[m]: for 3-axis someone could redo Pycam with cython
02:48 PM CaptHindsight[m]: that 5-axis reprap project uses Rhino plugins for CAM
02:48 PM CaptHindsight[m]: the chickens took the easy way
02:49 PM CaptHindsight[m]: https://arxiv.org/pdf/2202.11426.pdf
02:50 PM CaptHindsight[m]: https://forum.duet3d.com/topic/27648/5-axis-3d-printer-on-prusa-i3
03:04 PM XXCoder: saw that yeah
03:04 PM XXCoder: awesome indeed
03:07 PM roycroft: blah
03:08 PM roycroft: the new 4k display i just bought for my cad workstation has died
03:08 PM roycroft: just outside the return window, but still well within the warranty period
03:10 PM travis_farmer853: ouch
03:12 PM XXCoder: geez
03:12 PM Rab: roycroft, which brand/model?
03:12 PM XXCoder: in least its not a day after warranty lol
03:14 PM roycroft: spectre U279W-4000R
03:14 PM roycroft: the other day it would not turn on (i generally turn the display off when i'm done with work for the day)
03:14 PM roycroft: i unplugged it for 10 seconds, plugged it back in, and it came on
03:14 PM roycroft: today it did not come on even after doing that twice
03:15 PM roycroft: i plugged the old display in and it works fine, so it's not the computer or the cable
03:15 PM roycroft: i hope i still have the box for it
03:15 PM roycroft: i used to keep those boxes forever, but finally started purging them
03:16 PM roycroft: and i might have been getting a little bit overaggressive at purging - i should keep boxes at least until the warranty runs out
03:21 PM roycroft: er, it's sceptre, not spectre
03:23 PM * JT-Shop2 has to rearrange machines so the widened gantry fits back in roughly the same spot
03:24 PM travis_farmer853: with all this commentary, i feel like i am watching a movie, and forgot to turn the subtitles off ... πŸ˜‰
03:28 PM Tom_L: just wait til the baking channel wakes up
03:28 PM XXCoder: so you wait till baking channel rises?
03:29 PM travis_farmer853: baking channel??? LOL
03:41 PM travis_farmer853: how do you bypass a cat? don't they get angry with claws? πŸ˜‰
03:42 PM roycroft: catnip toys
03:43 PM travis_farmer853: ROFLMAO!
03:43 PM XXCoder: bypassing big cat is just smart. avoid risking your life
03:44 PM travis_farmer853: i have a mini-panther, and trust me, when the claws come out, i go the other way!
03:46 PM CaptHindsight[m]: JT-Shop2: or add a plasma cutter to it for a cutting and bending machine controlled by LCNC
03:48 PM JT-Shop2: way too slow lol
03:49 PM JT-Shop2: http://bendersplus.com/cgi-bin/p/awtp-product.cgi?d=dfw-equipment&item=22204
03:52 PM * Tom_L thinks this all started with a ridgline
03:52 PM Tom_L: and just kinda got out of hand
03:55 PM JT-Shop2: I've had the huth hb-10 for about 10 years or so
04:07 PM CaptHindsight[m]: https://www.youtube.com/watch?v=08f4tdAi1gU
04:36 PM JT-Shop2: I got an email from starlink that the RV antennas are in stock and ready for shipment... I doubt anyone is driving a RV much
04:37 PM XXCoder: might be way to get it faster lol
04:37 PM JT-Shop2: roycroft: now nothing is in a good place with the wood working equipment... going have to do some head scratching
04:37 PM XXCoder: install it on a rv, connect rv to house networking
04:37 PM XXCoder: who said rv would be going anywhere
04:37 PM JT-Shop2: rvs might be cheap right now lol
04:38 PM * JT-Shop2 doesn't have any room for or want a rv
04:38 PM XXCoder: I saw $2000 box truck. was kinda tempted lol but nah dont really need one
04:40 PM roycroft: if i had the room and the time to do the conversion i'd get a diesel pusher schoolie and convert that into an rv
04:40 PM roycroft: but i have neither the time nor the room for that
04:41 PM XXCoder: with gas prices it'd be way too exensive to move a rv
04:41 PM roycroft: i wouldn't be cruising with it all the time
04:42 PM roycroft: i'd be doing more of a drive to a destination, towing my car, parking the rv, and driving the car while exploring thing
04:43 PM XXCoder: yeah im saying even that much would be expensive
04:43 PM XXCoder: gas is over $5 a gal here
04:44 PM XXCoder: heard south calfornias at over $10?
04:45 PM JT-Shop2: weird note on the dro put into inc mode before turning off or your abs setting will default to zero
04:46 PM JT-Shop2: we drive to destination, check in, relax, get dinner, go to sleep
04:48 PM JT-Shop2: hmm the griz 3 in 1 sheet metal thing can go as well
04:48 PM CaptHindsight[m]: I dunnoh why I didn't think of adding Cython to Pycam years ago
04:49 PM CaptHindsight[m]: that would speed things up a bit, maybe 20-40x
04:49 PM CaptHindsight[m]: just the path tools
04:50 PM CaptHindsight[m]: XXCoder: low cost mobile home
04:51 PM JT-Shop2: https://www.grizzly.com/products/grizzly-30-3-in-1-sheet-metal-machine/g4011z
04:51 PM Rab: q
04:52 PM JT-Shop2: I don't think I paid that much for it years ago
04:57 PM roycroft: i sold one of those last spring (2021) for $600
04:57 PM flyback- is now known as flyback
04:57 PM roycroft: i paid $350 for it new about 20 years ago
04:58 PM roycroft: i was never very happy with it, even after completely refurbishing it
04:58 PM roycroft: those 3-in-1 machines just don't work very well
04:59 PM CaptHindsight[m]: i use mine for light stuff from time to time
04:59 PM JT-Shop2: yup you gotta adjust it every time almost for shear, roll and bend do ok
04:59 PM roycroft: i felt ok about selling mine
05:00 PM JT-Shop2: rain all around me atm
05:00 PM CaptHindsight[m]: think I got it at half price at HF and it hasn't cracked in half yet
05:00 PM roycroft: the guy who bought it is a metal sculptor, and just wante it for light shearing and freehand rolling stuff
05:00 PM roycroft: that machine will be fine for that
05:01 PM CaptHindsight[m]: it' doesn't like 1/8" alu
05:01 PM CaptHindsight[m]: or SS >18ga
05:01 PM CaptHindsight[m]: even 18ga SS is hard on it
05:02 PM roycroft: i do so little sheet metal fabrication i could not justify the space it occupied, even if it did work really well
05:02 PM roycroft: i sold my stretcher-shrinker too around the same time
05:02 PM CaptHindsight[m]: they have been known to shatter since the castings are so porous
05:02 PM roycroft: the grizzly version is probably a bit better than the harbor freight
05:03 PM roycroft: most grizzly stuff is
05:05 PM JT-Shop2: I do less and less metal work so time to gain space
05:07 PM CaptHindsight[m]: what is the last tool you'll have before you stop working?
05:07 PM travis_farmer853: brain
05:07 PM CaptHindsight[m]: over rated
05:07 PM travis_farmer853: lol
05:07 PM JT-Shop2: I was going to say bandsaw and welder
05:07 PM CaptHindsight[m]: people do fine without them
05:08 PM JT-Shop2: I went to an auction years ago for the high school shop teacher... you should have seen all the stuff he had in his basement
05:09 PM CaptHindsight[m]: I have an airgas supplier nearby, they are the most expensive and useless disti
05:09 PM JT-Shop2: I asked why he is selling it and he said "I'm done inventing"
05:11 PM travis_farmer853: i will be "done inventing" only when they put me into the ground...
05:11 PM JT-Shop2: as long as I can I will...
05:12 PM CaptHindsight[m]: put a bunch in a box marked "do not open until I'm gone"
05:12 PM CaptHindsight[m]: the last laught
05:12 PM travis_farmer853: LOL
05:12 PM CaptHindsight[m]: * the last laugh
05:14 PM JT-Shop2: Webb Pierce (old country singer) has a song where he says he's walking the dog all day and all night but I have no clue what that means
05:15 PM XXCoder: no idea
05:16 PM travis_farmer853: well, supper has arrived. so i bid you gentlemen good-night, until i wake up far too early tomorrow morning πŸ˜‰
05:20 PM JT-Shop2: enjoy
05:20 PM JT-Shop2: hmm the 15HH is made in Taiwan not china crap
05:28 PM JT-Shop2: https://genius.com/Webb-pierce-im-walking-the-dog-lyrics
05:29 PM JT-Shop2: And I'm walking the dog all the law allow
05:29 PM JT-Shop2: that line suggests something...
05:32 PM tcurdt: any 7i92 owner here that knows the difference between P3 and P5 power? is there a difference? the manual is not exactly clear on that
05:33 PM tcurdt: P5 has a connector, P3 does not
05:38 PM JT-Shop2: not sure what your asking... the 7i92 has two connectors
05:41 PM * JT-Shop runs my Mesa Configuration Tool and sees the 7i92 has P1 and P2 by looking at the schematic
05:42 PM JT-Shop: https://gnipsel.com/mesa/mesact/index.html
05:43 PM JT-Shop: P3 is the 5v power
05:44 PM tcurdt: JT-Shop2 this is from the manual https://imagebin.ca/v/6jsj1uiL3945 ... I have a connector on P5 ... nothing on P3
05:44 PM * JT-Shop runs my Mesa Configuration tool and opens the manual
05:45 PM JT-Shop: that's the same 5v bus
05:46 PM tcurdt: JT-Shop2 ok
05:46 PM JT-Shop: doesn't look the same as my manual you sure it's a 7i92
05:47 PM * JT-Shop thinks only a couple of boards have dual 5v...
05:48 PM * JT-Shop wanders down to look at a 7i92
05:51 PM JT-Cave: tcurdt, P3 is not used
05:52 PM JT-Cave: I need to see if the 7i92 manual has been updated
05:53 PM tcurdt: maybe I got an old version? it says "7I92 ETHERNET ANYTHING I/O MANUAL"
05:53 PM JT-Cave: yep the artwork has changed
05:54 PM JT-Cave: no, I had an old version lol
05:54 PM JT-Cave: but in any case use the connector for 5v
05:54 PM tcurdt: JT-Cave ok - thanks :)
05:55 PM * JT-Cave signs off for the night
06:00 PM tcurdt: good night
07:11 PM _unreal_: just posted a new photo, I assembled a bunch of parts. https://drive.google.com/drive/folders/1PAgv2L3UJL2gOle35AczsBejKtVXsq5d?usp=sharing
07:21 PM Rowow5457[m]: Just wanted to say thank you to any developers on linux cnc. Screw mach3 and everything else. I love the UI and everything about it so far. The motor tuning/motor steps is poorly designed but other than that I love it
07:22 PM XXCoder: its definitely great yeah
07:24 PM XXCoder: it started as emc2 project
07:25 PM XXCoder: goverment funded start of it, then released it. changed name due to name same as other compabny lawsuit
07:25 PM CaptHindsight[m]: Rowow: how would you fix the motor tuning?
07:26 PM * xxcoder8265[m] uploaded an image: (331KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/qZNmpVhaaSvIDPGwyqxPCKst/unknown.png >
07:50 PM Rowow5457[m]: adding a option to directly input steps per unit would be perfect. I have a belt system so obviously the forced lead screw calculation is weird. I had to randomly change units till I got the scale to get my units/mm. I tried directly changing the scale # in the ini file but that didnt work for whatever reason.
07:50 PM Rowow5457[m]: the calculation thing worked perfectly for my z axis otherwise.
09:40 PM CaptHindsight[m]: Rowow: what is you belt pulley ratio by the way?
09:41 PM CaptHindsight[m]: s/you/your/
09:41 PM Rowow5457[m]: not sure what you mean
09:41 PM Rowow5457[m]: its a directt belt drive, 24 teeth 3mm HTD
09:47 PM Rowow5457[m]: anyone got any suggestions on where to get extra long ball screws? like 10 feet long
10:07 PM ZincBoy[CAON]066: Call THK? You are going to need quite large diameter screw to be useful at a 10' length. Typically systems with that length of screw use a rotating nut instead of screw. The inertia of the screw becomes quite an issue.
10:08 PM XXCoder: yeah you have to scale up diameter with length
10:08 PM XXCoder: or you'll have fun ballscrew whupping
10:09 PM XXCoder: https://youtu.be/NWB6FAJCPhA
10:10 PM XXCoder: eh dunno if thats a real solution.
10:10 PM ZincBoy[CAON]066: Yes, the rotating nut design pretty much eliminates whipping but is much more complex.
10:11 PM XXCoder: I saw one guy buils a cnc, and he used 10mm ballscrew across what looks like 5 feet wide? forgot exact length
10:11 PM XXCoder: man I could see both sides whip around. it was way too heavu for that length and head weight
10:12 PM XXCoder: *heavy torque
10:13 PM ZincBoy[CAON]066: You can do that, you just have to go really, really slow. As long as you keep the RPM below the critical speed you are fine. Stiffness may not be acceptable though.
10:13 PM XXCoder: slow, and lower sideload
10:13 PM ZincBoy[CAON]066: There is a reason that almost all long travel systems go to rack and pinion.
10:14 PM XXCoder: his ballscrews was whipping around over inch around lol
10:14 PM XXCoder: then for even larger, ballscrews again, but much thicker
10:14 PM XXCoder: I used to run machines that have 3" ballscrews
10:16 PM XXCoder: if I recall right, rick and pinion have backlash issues. you dont want em on machines that is rated for .0001" precision and movement system that can detect .00001" (slight errors)
10:31 PM ZincBoy[CAON]066: Yes, my machine has 40mm screws for 30" of travel and I can hold 5um tolerances and detect 1um differences with the probe. Compared to a 10' screw I would expect a rack&pinion to perform better unless $$$$ were spent. You aren't getting tenths out of a 10' screw without active temperature control and your dynamic performance is likely to be worse than the R&P.
10:32 PM XXCoder: really comes down to what youre working on
10:32 PM XXCoder: wood routers? you can get away with fairly thick double belt system
10:32 PM XXCoder: error is bit larger but most wood projects just isnt that sensive
10:33 PM ZincBoy[CAON]066: I was looking at a roller chain system for a wood router. Some concerns with periodic error but as you say, for wood it isn't that much of an issue.
10:34 PM XXCoder: lcnc have error charting system but not sure how that works
10:35 PM XXCoder: essentally, somehow you figure repeatable motion error and have it adjust for it
10:35 PM XXCoder: it would solve periodic, in least damp it down
10:36 PM ZincBoy[CAON]066: I was looking at using it as I captured the error mapping table from my machine's control before I removed it. Then I figured out that the error units were um and the max error was 3um. I didn't think it was worth the bother at that point. Also, no real way to check to see if was helping.
10:37 PM XXCoder: thats just too tiny to worry about if its wood machine
10:41 PM XXCoder: I was thinking maybe linear position sensor for that but honestly never used that feature
10:42 PM -!- #linuxcnc mode set to +v by ChanServ
10:45 PM ZincBoy[CAON]066: That is the trick. To calibrate to the 1um level you need a way to measure position better than that. Pretty much need a laser interferometer and that is way too much of a pain to setup.
10:46 PM XXCoder: simple and good is 10x as sensive sensor as defined and wanted movement precision
10:46 PM XXCoder: a61 certainly had that
11:04 PM roycroft: i just ordered 10 spools of filament from gst3d
11:05 PM XXCoder: on the 30 day order savings?
11:05 PM roycroft: no, stuff in stock
11:06 PM XXCoder: slightly more money but in few days rather than month
11:06 PM roycroft: i'm going to order 20 more spools on the wait 30 days deal, but i'm going to wait another week or so for that
11:06 PM roycroft: because i do not want it to be delivered while i'm at the country fair
11:06 PM XXCoder: makes sense
11:07 PM roycroft: and this way i will be able to keep priniting
11:07 PM roycroft: i probably won't run out before the next shipment arrives - i also ordered some from atomic today
11:07 PM roycroft: colors that i need that gst3d don't hae
11:07 PM roycroft: have
11:10 PM XXCoder: its not often one fila store has all colors you want
11:13 PM XXCoder: roy https://youtu.be/egsEKeCXf60
11:14 PM XXCoder: woodworking on very old painting
11:14 PM XXCoder: love that channel. what he can do is insane
11:31 PM roycroft: i haven't seen that channel before
11:31 PM roycroft: it looks interesting - thanks
11:31 PM XXCoder: no problem
11:32 PM roycroft: jatobΓ‘ is a bitch to work with, btw
11:32 PM roycroft: i'm not sure i want to use it agin
11:32 PM XXCoder: its fairly rare but he does make equipment too. like huge clampator
11:32 PM roycroft: it's so hard and brittle and tears out so easily
11:32 PM XXCoder: and huge heated table
11:32 PM roycroft: i had enough material to make 60 drawer pulls, and i needed 48
11:33 PM roycroft: i decided to make 60, so i'd have some extras for other projects
11:33 PM roycroft: i've made this style many times before, and never had a problem
11:33 PM roycroft: this time i ended up wiht 49 out of 60 that were mostly usable, and a dozen or so of the 49 have tearout that i may not be abe to clean up
11:34 PM roycroft: they should look nice, though, the ones that didn't get wrecked
11:35 PM XXCoder: interestong
11:35 PM XXCoder: sounds like fairly weak internal hold
11:36 PM roycroft: i had to use extra clamps to hold the work in the internal jig, and it was still really grabby
11:36 PM roycroft: i needed to climb cut parts of it, and that was really hard to control
11:36 PM roycroft: but conventional cutting just ripped it apart
11:37 PM roycroft: this was with a brand new cutter, btw
11:46 PM XXCoder: wouldnt tape have helped?
11:46 PM XXCoder: tape line to be cut cut it and tape keeps tearout to minium
11:49 PM roycroft: it would not have helped at all
11:50 PM roycroft: i've never worked such grabby, splintery wood
11:50 PM roycroft: i still have to radius the edges of the pulls, and do the final sanding, but they're all machined now
11:52 PM XXCoder: not bad though yeah sounds like dont use that wood type again
11:53 PM roycroft: if i end up not liking how the pulls turn out i'll install them anyway and plan on making replacements some time in the future
11:53 PM roycroft: *AFTER* my cnc router is built :)
11:53 PM XXCoder: theres some interesting 3d printed pulls but honestly no idea how strong it would be
11:53 PM XXCoder: of course, it has to print flat since thats strongest at direction of pull
