01:53 AM Deejay: moin
03:10 AM Loetmichel: *meh* i should clean up my desk more often than every half year or "sedimentation" effects start to occur... I am not even half thru the 4m of desk and already found multiple tools i was searching for months now. (also found half a dozen #10 blades by cutting myself on them in the trash on the bottom of the "pile" :-)
03:16 AM XXCoder: lol
05:00 AM Tom_L: morning
05:53 AM jthornton: morning
05:53 AM XXCoder: heys
05:55 AM ehrenreich: Hi, if I use a MESA card would i then be able to run LinuxCNC on a newer Debian as i wont be needing the RTAI?
05:57 AM ehrenreich: looking at the MESA 6i25.
05:57 AM XXCoder: hey, dunno
06:03 AM jthornton: you can run any Mesa card on LinuxCNC Uspace
06:21 AM ehrenreich: ahh okay missed that. Thanks.
06:25 AM XXCoder: jt I guess it doesnt matter on rt since MESA handles stuff at realtime itself?
06:25 AM XXCoder: dunno how MESA works precisely
06:25 AM jthornton: yea RTAI is for software stepping
06:27 AM XXCoder: cool
06:34 AM enleth: do you know if HIWIN rail systems are designed to work inverted?
06:36 AM enleth: they resist being pulled off of the rail anyway, so I suppose they shouldn't care about being upside down as long as the force exerted by the suspended mass does not exceed the rating
06:38 AM enleth: to clarify - inverted and with the moving assembly actually suspended on them
06:39 AM sync: no, that's fine
06:48 AM SpeedEvil: Are tehy lubricated?
06:48 AM SpeedEvil: IF so, that might matter
06:55 AM enleth: NSK linear guide installation manual specifies this as a valid method, and they're pretty much indentical to HIWINs
07:16 AM elmo40: they wont matter. even if lubricated. it isn't gravity fed lube.
07:44 AM gregcnc: elmo40 did you sort your positioning issue?
09:37 AM SpeedEvil: https://imgur.com/gallery/DPN6tMv The real health dangers of 3d printing exposed.
09:41 AM nvz: _unreal_: did you get that timing belt thing figured out? idk if it was what you were looking for but I have like 12ft of timing belt and two pulleys left over from the kit I'd bought https://www.amazon.com/gp/product/B01KFO1P9K
11:07 AM flyback is now known as carlsagen-
11:07 AM carlsagen- is now known as flyback
12:25 PM Connor: looking to get a rotary table for the bridgeport. Is 10" too big? It has a 9" table...
12:35 PM perry_j1987: ok got a new rs485 module
12:35 PM perry_j1987: now i can verify that they both are doing the same thing
12:35 PM perry_j1987: so it must be something to do with the config on linuxcnc then
12:49 PM gloops: is 10" too big - well ive never had any complaints
12:49 PM Rab: gloops, 10" in diameter?
12:50 PM gloops: i thought we were talking radius
01:14 PM roycroft: lots of people put 10" rotary tables on bridgeport class mills
01:15 PM jdh: perry_j1987: noise maybe? when spindle is on, it is too much noise for serial link?
01:15 PM jdh: I am using shielded cable
01:16 PM jdh: near the drive anyway.
01:16 PM Rab: Anybody have any advice on small-scale machining of 303 stainless? I need to make a 22mm shaft, 7mm dia, with various simple turned features.
01:19 PM Rab: My starting approach is fairly low spindle speed but agressive feed rate w/cutting oil. Not my lathe, so I'm not sure what tooling is available.
01:40 PM perry_j1987: i suppose that could be
01:40 PM perry_j1987: just using twisted pair taken out of ethernet cord
02:40 PM serp: I have a sim up and I am trying to implement this: https://www.forum.linuxcnc.org/20-g-code/35367-scan-feature-to-move-around-maximum-boundaries?start=0#118960 I seemingly cannot get the .axisrc to load. When I try to run "O<boundaries-scan> call" in the MDI I get "Named parameter #<_hal[boundaries.xmin> not defined" error
02:41 PM serp: I have also tried to add that part using USER_COMMAND_FILE in the ini file but seemingly not loading that way either
03:07 PM serp: disregard that.. i had not turned on hal pins in gcode feature
03:52 PM Deejay: gn8
04:23 PM unterhaus: looks like Newark shipped my heatsinks. It's a little weird to say an order is processing when it's actually on the way across the ocean
04:37 PM * JT-Shop tries to think if he needs/wants any thing else from Automation Direct
04:40 PM Tom_L: JT-Shop, if you need a list i can help with that.
04:43 PM JT-Shop: lol
04:45 PM * Tom_L hears a big suction sound coming from the bank account as he returns from the tax appt
04:46 PM pink_vampire: SpeedEvil: how did it happen to you?
04:47 PM JT-Shop: taxes already?
04:47 PM SpeedEvil: What?
04:47 PM pink_vampire: the filament under your nail
04:47 PM unterhaus: I think we may actually get some back this year, bought a plug-in hybrid
04:48 PM Tom_L: JT-Shop, i like to get it over quickly
04:48 PM Tom_L: slow death isn't for me
04:51 PM JT-Shop: I don't even have any 1099's or w2's yet
04:54 PM SpeedEvil: Oh - no
05:53 PM __builtin: hi all
05:54 PM gloops: evenin
05:54 PM __builtin: I've been working on a web-based raster engraving G-code toolpather - any chance to have it included in the simple-gcode-generators repo?
05:54 PM __builtin: https://github.com/LinuxCNC/simple-gcode-generators/pull/11
05:56 PM gloops: nice one, any videos of this running __builtin?
05:57 PM __builtin: https://github.com/built1n/rastercarve
05:57 PM __builtin: example outputs above ^
05:57 PM jthornton: hmm for some odd reason I don't have write access to that sub repo...
05:58 PM jthornton: and I should have as I wrote most of them lol
05:58 PM gloops: oh yeah, i saw another app that does that
05:58 PM __builtin: photovcarve?
05:59 PM gloops: could be i cant remember, how does this work then, like a height map based on contrast?
06:00 PM __builtin: exactly
06:00 PM gloops: think they use similar for making light boxes
06:00 PM __builtin: a bunch of lines with varying Z-depth along them
06:01 PM __builtin: I've also tried my program with a pen plotter and it produces a very nice effect
06:01 PM gloops: looks good to me, they always ask how its done when someone posts an engraving on facebook
06:02 PM __builtin: it's really very simple
06:03 PM __builtin: I wrote this mostly because I learned how outrageously photovcarve was priced despite being so simple
06:05 PM gloops: well the cam is the part thats thin on the ground for open source cnc
06:06 PM __builtin: on the ground?
06:07 PM Tom_L: there's not much out there for free cam software
06:07 PM __builtin: ah
06:07 PM Tom_L: everybody starts one and quits before it's done
06:08 PM __builtin: haven't quit yet, have I?
06:16 PM sync: oh the effect is quite nice __builtin
09:21 PM veegee: Need to drill and tap some holes on the side of my vertical mill
09:21 PM veegee: How do I drill a nice perpendicular hole without a drill press?
09:31 PM Rab: veegee, mag drill.
09:33 PM Rab: Assuming a low budget, use a drill guide like this, or make one from a chunk of steel and clamp it to the side of the mill: https://smile.amazon.com/dp/B0061FY004
09:34 PM veegee: Ah yeah drill guide. Would need to make one for the specific sizes. That's the best way to go, thanks!
09:48 PM roycroft: veegee: big gator tools make some nice drill and tap guides
09:48 PM roycroft: i have several of them - they're great when you can't use a drill press/milling machine
09:48 PM veegee: I'll check it out, thanks
09:49 PM roycroft: https://www.shop.biggatortools.com/The-Ultimate-Big-Gator-Set-COMPLETESET.htm
09:49 PM roycroft: there's a nice set :)
09:50 PM roycroft: you can buy them at woodcraft or on amazon
09:51 PM roycroft: and, i'm sure, heaps of other places
10:00 PM Tom_L: doesn't look that handy
10:01 PM Tom_L: i'd rather have some round stock with a hole for individual ones
10:01 PM Tom_L: be fine if you have a wide open area
10:12 PM Rab: I don't have one, but I think the length gives you a square on one axis. It's easy enough to align a handheld drill on one axis by eye, less so in two dimensions.
10:14 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/X_Axis_tapped.jpg
10:14 PM Tom_L: made my own
10:14 PM Tom_L: got a better tap handle since too, that one was crap but i had it
10:25 PM beachbumpete1: Evening folks
10:31 PM beachbumpete1: Well I ran my first program on the VMC tonight after the bearing run in procedure
10:31 PM beachbumpete1: so far so good. Part looks great
10:31 PM Tom_L: good you got it goin again
10:32 PM beachbumpete1: Man I am so pleased
10:32 PM beachbumpete1: It really SUCKED having it just sit there unusable
10:51 PM veegee: I've been sitting here using my $300 mitutoyo micrometer as a fidget spinner
10:59 PM pink_vampire: veegee: some people have way too much money on their hands
10:59 PM fjungclaus1 is now known as fjungclaus
11:26 PM SpeedEvil: veegee: If you ain't enjoying it, it's wasted $.
11:36 PM elmo40: gregcnc, yes. i used office calc and rounded the values to nearest 0.01. my corners are a tad more crisp. might be the filament, might be my imagination... but other than that it is the exact same file (extrusion values and feed rate not changed)
11:36 PM elmo40: it was for my 3D printer.
11:37 PM elmo40: i didn't test on the mill yet. but i will venture to guess it can also have a benefit.
11:40 PM justan0theruser is now known as justanotheruser
