01:49 AM jpa-: and when your sketch blows up, ctrl-z your way out of.. trying to resolve constraint mess is way too annoying
04:46 AM JT-Cave: morning
09:40 AM lcnc-relay: <schoch_@> what is the difference between hal.py hal_glib.py and pyhal.py
10:17 AM JT-Woodshop is now known as C3-Shop
10:17 AM * C3-Shop puts the carburetor back on
12:37 PM rdtsc: agree with ya jpa... sketcher seems easy-to-use, until you need to design something "advanced" with repeating geometry then it blows up on ya
12:37 PM rdtsc: JT, that the old carb or the new one?
12:41 PM jpa-: rdtsc: yeah, i think the repeating stuff in freecad sketcher is often not very useful, using array operations after extrusion tends to work better
12:42 PM jpa-: similarly, ctrl-c ctrl-v within sketcher works weirdly, as you'd expect to be able to move the geometry afterwards but the constraints often prevent that
12:43 PM JT-Shop: rdtsc, I put the old carburetor back on so I can get an alignment Friday
12:49 PM Unterhaus__ is now known as Unterhausen
01:25 PM rdtsc: jpa, getting the hang of the W key (transform) for copying objects, helpful but then results in needing constraint tweaking
01:32 PM rdtsc: W key, enter number of copies (try 1), pick start point, then dest point
01:53 PM rdtsc: ...ended up drawing in QCAD and export DXF, import into Blender for tweaking, to STL for 3D print
01:54 PM rdtsc: Would much rather mill a piece of sheet steel for this, but of course the mill is still being built ;)
02:04 PM lcnc-relay: <big_kevin420@> schoch_@: hal_glib looks like its for the gstat thing
02:04 PM lcnc-relay: <big_kevin420@> pyhal.py looks like for comps written in opython?
02:05 PM lcnc-relay: <big_kevin420@> and hal.py looks like doing hal in pythion
02:05 PM lcnc-relay: <big_kevin420@> was i close?
02:13 PM lcnc-relay: <oddname_skane@> what do I need to change so that i see my bed like this
02:13 PM lcnc-relay: https://pasteboard.co/DOQJRw5iIMwM.png
02:14 PM lcnc-relay: <oddname_skane@> want it as I view from the door so to speak
02:27 PM lcnc-relay: <big_kevin420@> rotate the machine 180 degrees
02:28 PM roycroft: easier to rotate one's head, i should think
02:32 PM lcnc-relay: <big_kevin420@> oddname, are you running the machine yet or still setting it up?
03:17 PM lcnc-relay: <oddname_skane@> somewhat setup now
03:17 PM lcnc-relay: <oddname_skane@> finnished spindlecontrol today
03:17 PM lcnc-relay: <oddname_skane@> in theory I can machine now
03:18 PM lcnc-relay: <oddname_skane@> thinking of quickly making the chamber tight tomorrow and maybe test
03:18 PM lcnc-relay: <oddname_skane@> just need to setup spindlecooling
03:19 PM lcnc-relay: <oddname_skane@> hoses are in place just need to hookup to rad and pump and fill it
03:19 PM lcnc-relay: <big_kevin420@> do some machining first. theres very few use cases where you actually need to change the orientation of the preview.
03:20 PM lcnc-relay: <big_kevin420@> you might find that you didnt need to change it at all
03:24 PM lcnc-relay: <oddname_skane@> if I look at the machine and jog its confuses me 😄
03:24 PM lcnc-relay: <oddname_skane@> left = right etc
03:24 PM lcnc-relay: <oddname_skane@> but if I look at the screen all good
03:24 PM lcnc-relay: <big_kevin420@> yeah, its a perspective issue
03:24 PM lcnc-relay: <big_kevin420@> is the table moving right? or is the endmill moving left
03:25 PM lcnc-relay: <oddname_skane@> endmill left
03:25 PM lcnc-relay: <oddname_skane@> or glass half full or half empty 😄
03:26 PM lcnc-relay: <big_kevin420@> what gantry style? does the endmill move or does the table move?
03:26 PM lcnc-relay: <oddname_skane@> ahh table allways still
03:27 PM lcnc-relay: <oddname_skane@> print nc mini 🙂
03:27 PM lcnc-relay: <big_kevin420@> ok print nc
03:28 PM lcnc-relay: <big_kevin420@> ok, so for print NC gthe actually endmill is moving
03:31 PM lcnc-relay: <big_kevin420@> https://pasteboard.co/e47Hy2Q1mIoL.png
03:32 PM lcnc-relay: <big_kevin420@> check your movement, if your 0,0 is where is is, etc
03:33 PM lcnc-relay: <big_kevin420@> if you are in the back right corner, that should be max x,y
03:36 PM lcnc-relay: <oddname_skane@> hm I set it as 0,0
03:38 PM lcnc-relay: <big_kevin420@> thats fine,
03:38 PM lcnc-relay: <big_kevin420@> but that means front left has to be max xy negative
03:39 PM lcnc-relay: <big_kevin420@> so -100,-100
03:41 PM lcnc-relay: <oddname_skane@> set it as positive .D
03:41 PM lcnc-relay: <oddname_skane@> I want it as correct as possible of course
03:41 PM lcnc-relay: <oddname_skane@> what is the correct
03:41 PM lcnc-relay: <oddname_skane@> *most correct
03:43 PM lcnc-relay: <oddname_skane@> 0,0 front left feel most right to me
03:45 PM Tom_L: you can think of it as the table moving left or the spindle moving right ehh?
03:46 PM lcnc-relay: <oddname_skane@> i think the confusion is my setuo really 😄
03:46 PM lcnc-relay: <oddname_skane@> * setup
03:47 PM Tom_L: no the setup is fine, it's just you :)
03:49 PM lcnc-relay: <big_kevin420@> if front left is 0,0 that shouyld be fine
03:49 PM lcnc-relay: <big_kevin420@> either front left is 0,0 or its -100,-100
04:16 PM lcnc-relay: <gtkplusplus@> I'm getting some unexpected behaviour building from source when it comes to compiling components
04:16 PM lcnc-relay: <gtkplusplus@> or, well, is it expected to have some components error out or just be plain missing'?
04:16 PM lcnc-relay: <gtkplusplus@> * missing?
04:18 PM lcnc-relay: <gtkplusplus@> just to be sure before I start opening forum threads and delving into code I really don't know much about
04:19 PM Tom_L: may search that before creating one
04:21 PM lcnc-relay: <gtkplusplus@> I haven't found much which is why I was asking
04:21 PM Tom_L: building master? or 2.9?
04:22 PM lcnc-relay: <gtkplusplus@> master
04:22 PM lcnc-relay: <gtkplusplus@> well, a custom branch of master, but I didn't touch components
04:23 PM Tom_L: running the ./autogen.sh and ./configure ahead of make i assume
04:23 PM Tom_L: https://linuxcnc.org/docs/html/code/building-linuxcnc.html
04:23 PM lcnc-relay: <gtkplusplus@> yep, which already I had some issues with
04:24 PM lcnc-relay: <gtkplusplus@> but those I figured out and fixed
04:24 PM Tom_L: i haven't tried building master in quite some time
04:24 PM Tom_L: at times it could be broken
04:24 PM lcnc-relay: <gtkplusplus@> mmh, building master branch owrks
04:24 PM lcnc-relay: <gtkplusplus@> * works
04:25 PM Tom_L: is there something in .10 you need?
04:25 PM Tom_L: ok
04:25 PM lcnc-relay: <gtkplusplus@> not really, but I was trying to make a patch (thesis, I doubt I can get it working well enough) so I wanted to start from something recent
04:25 PM lcnc-relay: <gtkplusplus@> in case it actually work
04:25 PM lcnc-relay: <gtkplusplus@> * works
04:26 PM lcnc-relay: <gtkplusplus@> well, time to debug my code again and figure out why changes in tp break a component
04:26 PM Tom_L: you could also try checking out 2.9 and build against that
04:27 PM lcnc-relay: <gtkplusplus@> true
04:27 PM Tom_L: 2.9.3 whatever
04:27 PM lcnc-relay: <gtkplusplus@> since master compiles fine without my additions I'm blaming myself though
04:27 PM lcnc-relay: <gtkplusplus@> so I doubt much will change if using 2.9.3
04:27 PM Tom_L: also i forget the syntax but you can avoid building docs which makes the build like 3x quicker
04:28 PM lcnc-relay: <gtkplusplus@> eh, it takes like 3 minutes
04:28 PM Tom_L: not on my clunker
04:28 PM lcnc-relay: <gtkplusplus@> could probably cut that down further if I give it a bit more core
04:28 PM lcnc-relay: <gtkplusplus@> * cores
04:28 PM lcnc-relay: <gtkplusplus@> so I'm not too worried about build time
04:29 PM Tom_L: ./configure --enable-build-documentation=no
04:29 PM Tom_L: possibly
04:29 PM Tom_L: ./configure --disable-build-documentation
04:29 PM Tom_L: https://forum.linuxcnc.org/38-general-linuxcnc-questions/47636-build-2-9-rip-in-debian-12-without-documents
04:30 PM Tom_L: and any other switches you need
04:30 PM lcnc-relay: <gtkplusplus@> I'm reading them right now
04:30 PM lcnc-relay: <gtkplusplus@> I think default doesn't build documentation anymore
04:30 PM Tom_L: it used to
04:31 PM lcnc-relay: <gtkplusplus@> given that "--enable-build-documentation=FORMAT" is a flag
04:31 PM lcnc-relay: <gtkplusplus@> * switch
04:31 PM lcnc-relay: <gtkplusplus@> and it can be pdf, html or both
04:31 PM lcnc-relay: <gtkplusplus@> I'm guessing default is to not build
04:31 PM lcnc-relay: <gtkplusplus@> and I haven't seen anything related to docs being built so that track
04:31 PM lcnc-relay: <gtkplusplus@> * tracks
04:31 PM Tom_L: not sure about now but it used to build them all
04:32 PM Tom_L: maybe somebody fixed that
04:38 PM lcnc-relay: <gtkplusplus@> ok, so my error was something stupid, as usual
04:39 PM lcnc-relay: <gtkplusplus@> line ending was dos instead of unix on that file
04:39 PM lcnc-relay: <gtkplusplus@> now it errors out during compile but that's at least something I can track down
05:52 PM lcnc-relay: <skunkworks8841@> https://www.youtube.com/watch?v=xxA7VHYuYu8
05:54 PM xxcoder: open with players lol gonna love autocaptions
05:55 PM xxcoder: pretty interesting though
05:55 PM lcnc-relay: <skunkworks8841@> lol - sorry
05:55 PM xxcoder: nah not your fault lol. its pretty fun video
06:00 PM Tom_L: you're always diggin up something kinda cool
06:02 PM lcnc-relay: <skunkworks8841@> that is what I do... 😉
06:03 PM lcnc-relay: <skunkworks8841@> I have a ton of stuff here that I haven't even touched the surface of..
07:38 PM lcnc-relay: <skunkworks8841@> now that it is around 10f - the attic dehumidifier is only filling up every couple days.. lo
07:38 PM lcnc-relay: <skunkworks8841@> lol
07:39 PM xxcoder: lol
07:39 PM lcnc-relay: <skunkworks8841@> still 40%
07:39 PM xxcoder: im using 2 dehumidifers, but pretty small ones as I dont have enough power for large one.
07:39 PM xxcoder: 58% here sadly. still trying to get below 40%
07:45 PM lcnc-relay: <skunkworks8841@> the basement is I think 35 - then get higher as you move up
07:59 PM mrec: does anyone know a small spindle which can be put onto a compound of a minilathe?
08:00 PM mrec: I'd prefer something that is readily available for it before designing it myself
08:04 PM mrec: https://www.model-engineer.co.uk/forums/topic/tool-post-milling-drilling-attachment/
08:05 PM mrec: exactly something like that ...
08:11 PM lcnc-relay: <skunkworks8841@> so a high rpm/dremel/whatever good dremel like tool - isn't what you want?
08:12 PM mrec: no... I need it for tapping and milling slots into round parts (lathe)
08:13 PM mrec: a flexible system where I can change between stepper and BLDC would be suitable IBB guess
08:13 PM mrec: IBB... crap notebook types by itself..
08:15 PM mrec: I think I will have to do that myself..
08:24 PM Tom_L: is a sherline dc motor too big?
08:25 PM Tom_L: or a bldc around that size
08:27 PM mrec: for milling it should be fine, I think I can swap between two motors for milling and tapping I won't do that so often
08:27 PM Tom_L: https://www.amazon.com/Spindle-Waterproof-Drilling-Application-waterproof/dp/B08CN5PFN9
08:28 PM roycroft: how's the weather, tom_l?
08:28 PM Tom_L: i'd find some collet setup and mount a motor to it
08:29 PM Tom_L: roycroft, it's stopped snowing but going into single digits
08:29 PM roycroft: is it still blowing?
08:29 PM Tom_L: they issued an amber alert to stay home and off the highways
08:29 PM roycroft: yeah, welcome to north dakota :)
08:29 PM Tom_L: i think it's settling down som now
08:30 PM mrec: Tom_L: that's it great
08:31 PM Tom_L: i think that's just the head
08:32 PM mrec: yes that's perfect, I will just use two different motors for it
08:32 PM Tom_L: it's really hard to find those with low rpm bottom end torque
08:32 PM mrec: I will install that on the compound of the mini lathe and I will get my milling option
08:32 PM Tom_L: i found a 1.2kw spindle for my mill that maxed out around 5500 rpm
08:33 PM mrec: that's too big for the mini lathe I guess
08:33 PM Tom_L: mine?
08:33 PM Tom_L: probably
08:34 PM mrec: 1.2kw spindle
08:34 PM Tom_L: i wouldn't recomend it anyway, the guy took forever shipping it
08:34 PM Tom_L: but i have some links
08:34 PM mrec: I will get it from somewhere else anyway the picture was enough for searching it with google
08:38 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Spindle/Spindle_motor2.jpg
08:38 PM Tom_L: that's the one i got
08:38 PM Tom_L: sitting on a sherline spindle
08:39 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Spindle/Motor_mounted1.jpg
08:39 PM Tom_L: lots of torque
08:40 PM Tom_L: i had a china link to it but can't find it
08:43 PM -!- #linuxcnc mode set to +v by ChanServ
08:43 PM Tom_itx: https://www.alibaba.com/product-detail/310V-1-2kw-electric-motor-1200w_60737993181.html?spm=a2700.7724857.videoBannerStyleB_top.9.32c7751dTHUvzS
08:44 PM mrec: I think we were talking about that one earlier but for my option I will need position control as well
08:44 PM mrec: tapping stuff
08:44 PM Tom_L: i can tap with that
08:44 PM Tom_L: i put an encoder on it
08:45 PM mrec: the driver supports position control?
08:45 PM Tom_L: https://www.youtube.com/watch?v=Y4SQ74QLO50
08:45 PM Tom_L: i'm not sure it's exactly the same vfd
08:45 PM mrec: mine doesn't
08:45 PM Tom_L: i use linuxcnc for that anyway
08:46 PM Tom_L: with the encoder off to the side of the spindle with an index pulse
08:46 PM Tom_L: i didn't rely on the vfd for position
08:46 PM mrec: that driver is fast enough?
08:46 PM mrec: well stupid question seems like yes
08:47 PM Tom_L: watch the end of the yt
08:47 PM Tom_L: err the middle rather
08:47 PM Tom_L: that's where i tap
08:47 PM mrec: I saw it yes
08:47 PM mrec: interesting.
08:48 PM mrec: my application is just a very rare use so I will probably stick with something below 60W
08:48 PM Tom_L: i did that with a sherline dc motor before getting that one as well
08:48 PM mrec: steppers I have enough BLDCs too
08:49 PM mrec: thanks for the information, I need to leave now.
08:49 PM Tom_L: later
08:50 PM Tom_L: i did get some chinese docs for that vfd finally
08:50 PM Tom_itx: http://en.lanjiukeji.com/product/754.html
08:50 PM Tom_L: pretty sure that's the same driver
08:51 PM Tom_L: mine is 120v though
10:48 PM xxcoder: wow sounds like heaviest snowfall in a decade is happening in usa
11:14 PM xxcoder: Tom_L: watched the modify stl one. nice
