04:25 AM Tom_L: 38°F
04:37 AM Tom_L: high 54°F
05:20 AM Lunar_Soda: Greetings
05:23 AM Lunar_Soda: This is the first time in my life i have used IRC, so I will introduce myself. Im Daniel and i study machine engineering. I have made a small 160x700mm lathe. I have some previous coding experience (I worked two years as a python programmer). Im interested in sharing thoughts and experiences as well as contributing to the project.
05:47 AM JT-Cave: morning
05:47 AM JT-Cave: 29°F
05:54 AM CloudEvil: hey
06:48 AM JT-Cave: rooster just coughed
07:23 AM Tom_L: don't eat too much today
07:56 AM JT-Cave: starting out pretty light
07:59 AM Tom_L: gonna be a lazy day here. the girls went to colorado
07:59 AM Tom_L: just our two and us
08:41 AM JT-Cave: just the 13 of us today
08:43 AM Tom_L: that should liven things up
08:55 AM JT-Cave: well the 8 hens are usually pretty quiet and the 3 cats sleep a lot so pretty quiet in general unless I shoot the cannon
08:59 AM Tom_L: haha
09:00 AM Tom_L: tell the hens the're lucky to be hens today and not turkeys
09:15 AM JT-Cave: left the short hose connected last night so gotta wait for it to thaw out...
09:53 AM lcnc-relay: <Lcvette> Happy Thanksgiving all!
09:53 AM lcnc-relay: <Lcvette> * Happy Thanksgiving All!
09:54 AM JT-Cave: Happy Thanksgiving
10:05 AM JT-Cave: Tom_L, there are two ways to run the new gui, build and install the deb or have an Axis sim running and launch it from the repo
10:19 AM lcnc-relay: <Lcvette> JT: you make an updated gui builder? 😲
10:28 AM JT-Cave: yes, a very free form gui based on PyQt6
10:35 AM lcnc-relay: <Lcvette> sweet
10:36 AM Roguish: good morning all
10:36 AM Roguish: Hey Chris...
10:37 AM Roguish: sunshiny day out here http://www.rntl.net/san-francisco-windsurfing-cams/
10:38 AM JT-Cave: sunny and cool here... at least it's not snowing lol
10:39 AM JT-Cave: did a lot of work to the BlueWing just in time for winter...
10:40 AM lcnc-relay: <Lcvette> hey noel!
11:11 AM JT-Shop: hmm I just had an idea if there is a .ui file in the same directory as the ini file load that
11:13 AM Tom_L: will that load the rest?
11:13 AM JT-Shop: rest?
11:13 AM Tom_L: supporting code behind the ui widgets
11:14 AM JT-Shop: that's loaded before the .ui file is brought in
11:14 AM JT-Shop: so all you need to test a .ui is to put it in the same directory and say DISPLAY = emc
11:14 AM JT-Shop: or whatever I end up calling it
11:15 AM JT-Shop: that way all you need is the python code installed
11:16 AM JT-Shop: and you can change the ui all you want
11:17 AM JT-Shop: for now you can have Axis running and run the code local
11:24 AM JT-Shop: nap time
12:30 PM lcnc-relay: <sodakaustik> Where is this relayed chat happening?
12:30 PM bjorkintosh: which?
12:31 PM bjorkintosh: this is irc.
12:31 PM bjorkintosh: the first and the best of its kind.
12:33 PM Tom_L: you got questions, we got answers
12:49 PM Unterhaus_ is now known as Unterhausen
12:49 PM Unterhausen: the machinekit email list seemingly just got a random malware file
12:51 PM Tom_L: samples have been :)
12:53 PM lcnc-relay: <JT (@jt-shop:matrix.org)> What I think I'll do is if a ui file name is in the display section I'll use it, if not I'll use the stock one
01:06 PM solarwind: CaptHindsight where are we on that lathe
01:06 PM solarwind: chop chop now!
01:07 PM CaptHindsight: just getting Mr Sandman out of my eyes
01:09 PM solarwind: my lathe spindle specs are listed as: https://aceronline.net/acergroup/el-spel1440v.htm
01:09 PM solarwind: what does it mean "type of spindle nose MT 5", when it states the taper of center is MT 3?
01:09 PM CaptHindsight: 1.25 um runout on that spindle
01:09 PM solarwind: yeah I measured and verified
01:09 PM solarwind: it meets specs, I'm very pleased
01:11 PM solarwind: it's very rigid, I see no chatter even when I turn a large diameter part in high gear and can hear the motor reaching its limits
01:11 PM solarwind: I need to figure out a way to add a spindle encoder
01:12 PM solarwind: and locks on all the axis... I have no idea why this thing doesn't come with way locks
01:13 PM solarwind: depending on the tool used, the cutting forces are easily enough to move the Z axis on a large facing cut
01:14 PM solarwind: The only problem is, the DRO scales are right over the area where you'd drill a hole to make a lock that pushes against the gib
01:18 PM solarwind: Only other way is to replace the leadscrews with ballscrews and lock the screws, which I need to do anyway
01:26 PM CaptHindsight: I'd leave it and get or build a CNC lathe
01:27 PM solarwind: I still want way locks!
01:27 PM solarwind: how can you not have locks?
01:28 PM solarwind: it's not possible to do a facing cut without holding the Z axis wheel, and that necessarily means instability
01:28 PM solarwind: I'm not opposed to getting a CNC lathe, but they're not nearly as available as VMCs in the area for some reason
01:29 PM solarwind: also I hate acme screws and backlash. I really like the direct feel of ball screws
01:29 PM CaptHindsight: life finds a way
01:30 PM solarwind: and I dn't get what it means by "type of spindle nose: MT 5"
01:30 PM CaptHindsight: extend the screw and add a brake
01:30 PM solarwind: there would still be backlash and I HATE that
01:30 PM solarwind: it's a D1-4 cam lock mount
01:31 PM CaptHindsight: well it's a used lathe
01:32 PM CaptHindsight: now you know what to look for
01:33 PM solarwind: Well I looked for important aspects of it like tolerances and slideway condition
01:34 PM solarwind: and it was well taken care of so I'm happy about that
01:35 PM CaptHindsight: be content with what you have, some people don't even have lathes or even worse they have this https://www.mscdirect.com/product/details/76008135
01:35 PM XXCoder: owning that thing is worse than not having a lathe?
01:36 PM solarwind: okI don't get it, what's wrong with that lathe?
01:37 PM lcnc-relay: <JT (@jt-shop:matrix.org)> https://matrix.org/_matrix/media/v1/download/matrix.org/FwqViefpihHasdYmDbKYGdcR
01:37 PM XXCoder: thats great. cant wait to eat it ;)
01:37 PM solarwind: Worse is having the mini mill and mini lathe this guy has: https://www.youtube.com/watch?v=91pomft40NM
01:38 PM solarwind: He does really good work, but you can see the whole damn thing flex a few mm in every shot lol
01:38 PM lcnc-relay: <JT (@jt-shop:matrix.org)> Hurry up and get here
01:39 PM solarwind: I would cry if I could see any visible flex in my machines
01:39 PM XXCoder: sure you work with tools and know limitions, and majke good parts
01:41 PM lcnc-relay: <JT (@jt-shop:matrix.org)> I knew a guy with a very long lathe and he had +- marks down the ways so he knew when to adjust the cross slide to get a straight cut
01:50 PM roycroft: i wouldn't say that's really good work
01:50 PM roycroft: i think i could do just as good a job
01:51 PM roycroft: but my first concern is that he turned the collet side of it first, indexing off the rough shank of the bar
01:51 PM roycroft: then he turned the spindle taper, indexing again off that rough bar shank
01:52 PM roycroft: i'd have turned the spindle taper first, and mounted the collet holder in the spindle as it will run, and then use that setup to turn the collet taper and collet nut threads
01:52 PM roycroft: that would be much more accurate
01:57 PM XXCoder: roycroft: or witness mark
01:57 PM XXCoder: that can be used for measuring stuff then cut off
01:58 PM roycroft: turning it in place will always be the most accurate way of doing it
01:58 PM CaptHindsight: use whatcha got
01:58 PM XXCoder: yeah
01:58 PM XXCoder: capt yep
01:58 PM roycroft: there may be other methods that approach that accuracy
01:58 PM roycroft: but none can surpass it
01:58 PM roycroft: and there's no reason he could not do it that way
01:58 PM CaptHindsight: some people have lathes and some have Enco's
01:58 PM roycroft: it's not a use what you have issue
01:58 PM roycroft: it's an order of operations issue
01:59 PM CaptHindsight: some use people order differently others than
01:59 PM roycroft: turn the spindle taper and drill and tap the drawbar hole
01:59 PM roycroft: mount the part in the spindle
01:59 PM roycroft: now it's perfectly indexed
01:59 PM roycroft: perform all other operatins
02:00 PM roycroft: operations
02:00 PM solarwind: Well not necessarily that particular video, he does good stuff in general
02:01 PM solarwind: CaptHindsight but I still don't get the joke about the Enco
02:01 PM roycroft: i've not seen any of his other videos
02:01 PM solarwind: are they really that bad?
02:01 PM roycroft: that video was better than many, perhaps most, on the youtube
02:01 PM roycroft: but it was still mediocre machining
02:01 PM XXCoder: artisn makes isnt best but still enjoyable
02:01 PM roycroft: enco are typical imported machines
02:01 PM roycroft: decent castings, poor fit and finish
02:02 PM CaptHindsight: made of grey butter
02:02 PM roycroft: they are essentially machine kits that can be made to perform semi-precisely
02:03 PM roycroft: but a skilled machinist can make good parts with a semi-sloppy machine
02:03 PM roycroft: it's noon here
02:04 PM roycroft: time to play alice, one of my annual traditions
02:04 PM CaptHindsight: we had noon a couple of hours ago
02:04 PM * roycroft ponders playing the nixon tapes version vs. the original
02:05 PM CaptHindsight: when JT posted the pic of the bird I was looking for the mechanisms to turn it
02:06 PM roycroft: i'll be heading out in a bit, but i'm going to try to do the rough milling of the wood i bought yesterday and glue up the wide pieces before i go
02:06 PM roycroft: so i can get real progress done on that project tomorrow
02:06 PM roycroft: i was impressed - my moisture meter says the pieces of wood are between 6 and 9 percent moisture
02:06 PM roycroft: that's plenty dry, and even lower than the wood stores in my shop
02:07 PM lcnc-relay: <JT (@jt-shop:matrix.org)> If you turn the bird the butter will fall out
02:07 PM roycroft: it could be because i bought ash, and i think i'm the only person in eugene who buys ash on a regular basis, so it's probably been sitting around at the hardwood purveyor's for a while
02:08 PM XXCoder: why dont people buy ash?
02:09 PM roycroft: i don't know - it's a wonderful wood to work with it's cheaper than white oak, and it looks amazing
02:09 PM roycroft: i think in part because people know what oak is but they don't know what ash is
02:09 PM roycroft: and sadly, red oak is making a big comeback
02:09 PM roycroft: here come the '80s again
02:10 PM XXCoder: we all live in time loop
02:10 PM roycroft: i'm waiting for "avocado" and "mustard" to return to the interior design vocabulary
02:10 PM roycroft: but even worse, there could be a shag carpet revival
02:14 PM lcnc-relay: <JT (@jt-shop:matrix.org)> LOL
02:14 PM XXCoder: fun lol
02:14 PM CaptHindsight: there was a shag carpet revival, you blinked and missed it
02:15 PM lcnc-relay: <JT (@jt-shop:matrix.org)> I'm steam bending some white oak when the strap thingy shows up
02:36 PM XXCoder: excellent tony video
02:37 PM CaptHindsight: there was a short 70's interior design revival right and during covid
02:38 PM CaptHindsight: it appealed to those born in the 80's and 90's
02:38 PM CaptHindsight: since they didn't have to live through it the first time
03:01 PM XXCoder: yo
03:05 PM lcnc-relay: <JT (@jt-shop:matrix.org)> Yo
04:04 PM Tom_L: what a mess
04:04 PM XXCoder: what was a mess?
04:04 PM Tom_L: all i wanted to do was draw a part. the mouse software was bonked and wouldn't instal right. the MB USB firmware was bonked too
04:05 PM Tom_L: and the mouse was discontinued
04:05 PM Tom_L: but i fixed it and it's working. i've lost interest in drawing the part now though
04:07 PM lcnc-relay: <JT (@jt-shop:matrix.org)> Lol
04:07 PM XXCoder: doh yeah sometimes small failure causes loss of interest
04:07 PM lcnc-relay: <JT (@jt-shop:matrix.org)> Turkey is almost done
04:08 PM Tom_L: things are about ready here as well
04:08 PM Tom_L: i think the rolls are going in the oven atm... a good sign
04:08 PM lcnc-relay: <JT (@jt-shop:matrix.org)> https://matrix.org/_matrix/media/v1/download/matrix.org/AFHrwUzVnwHzXKWBLKrvCZYG
04:08 PM lcnc-relay: <JT (@jt-shop:matrix.org)> Yup
04:08 PM lcnc-relay: <JT (@jt-shop:matrix.org)> No rolls here
04:09 PM Tom_L: looks a bit browner now
04:09 PM Tom_L: she wanted to try some new things so we'll see
04:09 PM lcnc-relay: <JT (@jt-shop:matrix.org)> Yup
04:11 PM lcnc-relay: <JT (@jt-shop:matrix.org)> Getting chilly out here
04:12 PM Tom_L: 'mini pecan pies' for desert with ice cream on top
04:12 PM Tom_L: done in large cupcake pan
04:12 PM Tom_L: tested one.. i'm sure that's a winner
04:13 PM Tom_L: windows n doors been open here all day but it is cooling down
04:14 PM lcnc-relay: <JT (@jt-shop:matrix.org)> I've not had a pecan pie in a long time
04:14 PM Tom_L: me either
04:16 PM lcnc-relay: <roguish> oooo. Pecan pie is my favorite...
04:37 PM mrec: does tapping oil really make such a difference? I'm currently just using some coolant for tapping various M3 screw threads
04:37 PM mrec: I have to tap around 100 screw holes actually.
04:37 PM mrec: in stainless steel 416
04:40 PM CaptHindsight: mrec: I've done similar with wd40, hand tap in a cordless drill
04:40 PM mrec: M3 in a cordless drill?
04:41 PM mrec: a few threads for sure will be okay but they will break relatively soon if tapping is not supported
04:41 PM CaptHindsight: yeah and the tap drill
04:42 PM mrec: I have to make some special screws for my smd feeders, I'm upgrading the feeders on the go.
04:42 PM CaptHindsight: how deep are you going?
04:42 PM mrec: just ~5mm
04:42 PM Tom_L: mrec, tapping fluid does help
04:42 PM XXCoder: when I worked, I also used the tap grease. just dab on bottom of tap and off it gp
04:43 PM CaptHindsight: keep it cool so it doesn't harden
04:43 PM mrec: M3 will not not harden much... and not heat up
04:44 PM CaptHindsight: it will with a dull drill :)
04:44 PM mrec: tapping not drilling
04:45 PM CaptHindsight: you're lucky to already have holes
04:46 PM mrec: the holes are only 8-9mm I'm using a small drill with this yes
05:19 PM CaptHindsight: 🦃
06:29 PM Guest82: HELLO
06:30 PM XXCoder: hey
06:37 PM Guest82: Can you tell me if running LinuxCNC on a Raspberry Pi is stable?
06:40 PM Tom_L: it has been done
06:40 PM firephoto__ is now known as firephoto_
06:41 PM pcw-home: Stable though may not work with the more exotic GUIs
06:41 PM Tom_L: should be ok with axis
06:41 PM Tom_L: i tested one with axis and it did ok
06:42 PM Tom_L: you can tweak the config and get a little better latency
06:42 PM Tom_L: i don't have the tweak notes but maybe skunkworks does
06:44 PM Guest82: Thank you very much.
06:45 PM XXCoder: rpi5 is still untested in linuxcnc terms so far I know
06:45 PM XXCoder: rpi4 yeah as tom said
06:51 PM Guest82: Thank you.
06:52 PM Tom_L: Guest82, https://www.youtube.com/watch?v=g0OLIth_cOI
06:57 PM Guest82: Three years ago, you were already using it. Elderly level, well-versed.
07:54 PM XXCoder: Tom_L: man one of my earliest jobs was tube slotting
07:54 PM XXCoder: it was bit nervious because i was new, and hurco suck, because if you pause, it would go up to home. which is bad for tube lol
07:59 PM Tom_L: hurco's were odd machines
08:00 PM XXCoder: yeah
08:00 PM XXCoder: i thought it was cool, till I ran other machines
08:01 PM XXCoder: it was so much more limited than machines 30 years older than it
08:01 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Can_holder_assy.jpg
08:01 PM Tom_L: for cutting those tubes
08:02 PM XXCoder: still in progress eh? I remember triggers from couple years ago
08:02 PM Tom_L: he still makes em
08:02 PM XXCoder: tubes I cut was 5 feet wide arylic tube, using slotting saw
08:02 PM Tom_L: just trying to gradually improve the process
08:02 PM Tom_L: he uses a wood router now
08:02 PM XXCoder: it was tuve lighting covers for airplanes
08:03 PM XXCoder: interesting
08:34 PM serp8 is now known as serp
