12:42 AM Deejay: moin
03:16 AM mrec: aliexpress.com/item/1005003338600600.html
03:17 AM mrec: are those spindles worth it for small tasks on a lathe?
03:42 AM jpa-: they are ok for small toolbits that you'd use at 12krpm, but at lower speeds the torque is inadequate
03:58 AM mrec: well I just want to mill a D shaped stick 4-5mm diameter
03:59 AM mrec: https://snipboard.io/7y9inJ.jpg
03:59 AM mrec: currently I use my mill and the A axis, I just mill the stick rather than turning
04:00 AM mrec: https://i.snipboard.io/51kbrF.jpg
04:00 AM mrec: that's a better view
04:44 AM Tom_L: mrec, steel, wood, plastic, inconel?
04:44 AM Tom_L: morning
04:45 AM Tom_L: a sherline spindle is ~600w but lower rpm
04:45 AM Tom_L: if that's all you plan to do with it, it may work on smaller things but remember those are chinaco watts
04:46 AM Tom_L: and at what rated rpm?
04:47 AM mrec: steel
04:47 AM mrec: soft steel
04:47 AM Tom_L: i would have my doubts
04:47 AM Tom_L: for a couple reasons
04:48 AM Tom_L: the peak power is going to be at an rpm probably too high for the meterial you're cutting
04:48 AM mrec: it's just a few mm stick with a small tool the power shouldn't matter too much
04:49 AM Tom_L: at that price it probably wouldn't break the bank either way...
04:51 AM Tom_L: it wouldn't be very useful at low rpm though
04:54 AM mrec: I think I can try some of my other motors first
04:54 AM mrec: so I better just get some ER20 collet adapters
05:50 AM NoSpark: are there any open source ethernet board compatible with linuxcnc?
06:10 AM JT-C8: morning
06:10 AM JT-C8: brb
06:37 AM travis_farmer: Morning :-)
07:35 AM Tom_L: 41F
07:37 AM travis_farmer: 63F, and pouring rain
07:55 AM jpa-: mrec: if it is a manual lathe, go for a lower RPM spindle with more torque.. otherwise you'll get tired doing shallow passes with 3mm endmills
12:48 PM Unterhaus_: I went to the local welding supply and fittings were cheaper than online. Made me feel guilty for looking
12:50 PM Unterhaus_ is now known as Unterhausen
12:50 PM Unterhausen: mostly I didn't want to have to drive out there though
04:55 PM Unterhaus_ is now known as Unterhausen
06:14 PM rigid: pere: you got an image of your cnc?
06:14 PM rigid: to get an impression
06:46 PM Unterhausen: youtube decided to serve me up a video about someone who had lost their instagram account and associated income
06:47 PM Unterhausen: turns out it was because their birthday was wrong. I lied to insta about my birthday because it's none of their business
07:04 PM CloudEvil: Were they under 13/18?
07:05 PM CloudEvil: Because that can get funky regulations wise
07:05 PM Unterhausen: apparently their birthday was missing altogether due to a software glitch on insta's end
07:05 PM CloudEvil: ah
07:05 PM Unterhausen: it took a FB employee seeing a youtube to get it fixed
07:07 PM Unterhausen: I would call my congressman's office
07:07 PM CloudEvil: Yeah, corporations where you're the product are a problem.
07:07 PM Unterhausen: I hear fb actually does answer the phone for congresscritters
07:07 PM CloudEvil: They have almost no interest in customers other than how cheaply they can process them and avoid lawsuits
07:08 PM Unterhausen: there is no way fb should have been allowed to buy insta
07:09 PM Unterhausen: I was hoping fb/meta/insta would die, and then Mu_k killed twitter and gave them new life
07:09 PM CloudEvil: :/
07:14 PM Unterhausen: insta gave him the opportunity to appeal and then deleted his account 30 seconds after he did
07:14 PM Unterhausen: it was for human trafficking content
07:21 PM Unterhausen: I wonder when we'll actually be able to buy a RPi5 and how much
07:26 PM roycroft: all that stuff has always been dead to me
07:27 PM roycroft: teh social media stuff ,that is
07:27 PM roycroft: rpi 5 should be out late october, and a lot of folks have pre-ordered it
07:28 PM roycroft: the question is: how long will they be backordered after the intial batch ships?
08:01 PM Unterhausen: Adafruit has apparently been burned by Rpi orders before, your account has to be validated
08:01 PM Unterhausen: to order one
08:02 PM Unterhausen: I have wondered why they bother selling rpis there
08:03 PM roycroft: They're all about rpis
08:03 PM roycroft: at least rpi shields and other accessories
08:05 PM Unterhausen: maybe that's it, drives other sales
08:14 PM roycroft: yeah
08:14 PM roycroft: there's probably no margin on the pi
08:14 PM roycroft: and it's a pain in the butt to try to stock
10:01 PM pere: rigid: Mazak VQC 15/40 is shown in operation in <URL: https://yewtu.be/watch?v=9f6HYiclwd8 >. Similar to the one in question, but with different colour. :)
10:03 PM pere: rigid: <URL: https://github.com/SebKuzminsky/MazakVQC1540/tree/bon-dev > is the linuxcnc setup.
10:11 PM rigid: pere: dude! that's some beast
10:11 PM pere: 4.5 tonn. :)
10:11 PM rigid: btw. currently bisecting for that "gcode-output not found" bug
10:13 PM rigid: and I was suspecting that --enable-build-documentation=N still builds documentation. But didn't confirm that, yet
10:14 PM rigid: that'd be the first thing to do to optimize CI runs btw. installing all deps necessary to build the docs takes looong. not all jobs need to build the docs
10:15 PM pere: yeah. I use ./debian/configure no-docs to drop docs when testing the code. but I mostly work on the documentation, so I rarely can do that.
10:15 PM rigid: oh, there's a separate configure script for debian. TIL...
10:16 PM rigid: yeah, there are still asciidoc/a2x runs, despite --enable-build-documentation=N :-(
10:17 PM pere: manual pages are considered part of the code, not documentation as such. :)
10:17 PM rigid: hm
10:18 PM rigid: so if I wanted an ultra ligthweight build for a minimum profile install where I don't need docs, I had to delete man pages manually :-/
10:32 PM pere: for that, the definition of docs would need to be adjusted.
10:45 PM rigid: like manuals not being documentation? nah
10:46 PM rigid: gentoo doesn't build man pages when docs are disabled.
10:47 PM rigid: oh, at least some ebuilds don't
10:48 PM rigid: anyway, I think it'd be nice to not have to run that heavy thing during build when it's not needed.
11:00 PM pere: yeah.
11:01 PM pere: Look like <URL: https://github.com/LinuxCNC/linuxcnc/pull/2678#issuecomment-1751907124 > need your input.
11:01 PM pere: btw, why did we switch from #linuxcnc-devel to #linuxcnc?
11:05 PM rigid: oh didn't notice. sry.
11:05 PM rigid: wanted to see you cnc and then forgot :)
11:05 PM rigid: *your
11:09 PM pere: not a problem, just curious. not convinced the audience on #linuxcnc are interested in master git tests scripts every time, though. :)
