01:47 AM CaptHindsight[m]: Tom_L nice, let me know what the lash is like after it gets broken in
01:55 AM CaptHindsight[m]: https://www.automationtechnologiesinc.com/products-page/cnc-parts/cnc-router-rotational-axis-the-4th-axis this one costs more and is only belt drive and a bit smaller, but comes with a motor
02:27 AM Deejay: moin
04:22 AM JT-Cave: morning
05:00 AM Tom_L: morning
05:02 AM Tom_L: https://www.youtube.com/watch?v=5xIwtoPkHY0
05:02 AM Tom_L: indexer
05:02 AM Tom_L: more to test the post than anything
05:46 AM JT-Cave: pretty neat, I wish my dividing head worked
05:56 AM sensille: huh? my f360 post processor settings are gone
05:57 AM sensille: and of course i have no idea what i've used there
05:59 AM XXCoder: backups?
05:59 AM sensille: of course not
06:00 AM XXCoder: sucks. you used any site to read to configure it last time?
06:03 AM sensille: no idea. at least there is a linuxcnc (emc2) in the library
06:06 AM sensille: doesn't seem to blow up my machine immediately ...
06:29 AM JT-Cave: hmm how to mount my nas so I can get a list of files in python?
06:39 AM tiwake[m]: JT-Cave: you using nfs?
06:39 AM JT-Cave: nfs is enabled on the nas yes
06:40 AM tiwake[m]: then use that
06:40 AM JT-Cave: in /etc/fstab?
06:41 AM JT-Cave: https://linuxhint.com/mount_nfs_share_debian/
06:42 AM tiwake[m]: nfs is the best way to have NAS with linux or BSD
06:43 AM tiwake[m]: otherwise its treated just like a folder
06:44 AM tiwake[m]: or any other mounted device
06:45 AM tiwake[m]: SMB and others I've found to be flakier in general
06:46 AM JT-Cave: testing now
06:47 AM -!- #linuxcnc mode set to +v by ChanServ
06:47 AM tiwake[m]: https://linuxconfig.org/how-to-configure-nfs-on-linux seems good
06:51 AM tiwake[m]: I had nfs set up with my server in containers through proxmox
06:51 AM tiwake[m]: which is a reallllllly weird way to do it... kinda difficult because of permissions
07:01 AM JT-Cave: that tutorial is for setting up a nas server which is not what I want to do I don't think
07:02 AM tiwake[m]: you can make sure the nfs service is running on the server
07:02 AM tiwake[m]: and check what folders are being served
07:02 AM JT-Cave: the nas has nfs enabled
07:04 AM tiwake[m]: and the nfs server service is running?
07:04 AM JT-Cave: I guess it is it has a green bar
07:05 AM tiwake[m]: can you ssh in to the NAS?
07:07 AM JT-Cave: yes
07:10 AM tiwake[m]: so... ssh in and check nfs configuration files
07:11 AM JT-Cave: how/where do I check nfs configuration files?
07:11 AM tiwake[m]: what is your NAS?
07:11 AM JT-Cave: readynas, when I do ls on the ssh I only see one directory...
07:13 AM JT-Cave: ah I have to set the network access for each directory on the nas
07:13 AM tiwake[m]: https://kb.netgear.com/23098/How-do-I-configure-Network-File-Service-NFS-settings-on-my-ReadyNAS-OS-6-storage-system
07:14 AM JT-Cave: nfs is already enabled
07:15 AM tiwake[m]: well, I don't know how netgear stuff works exactly
07:15 AM tiwake[m]: its been a zillion years since I last used any of their products
07:18 AM tiwake[m]: and yeah it does seem you need to set based on folder
07:18 AM tiwake[m]: https://kb.netgear.com/22881/How-do-I-set-network-access-rights-to-shared-folders-on-my-ReadyNAS-OS-6-storage-system
07:19 AM tiwake[m]: https://kb.netgear.com/23181/How-do-I-access-a-shared-folder-on-my-ReadyNAS-OS-6-storage-system-by-using-a-network-attached-Linux-or-Unix-device and scroll down to the NFS section
07:20 AM JT-Cave: that's what I've been trying to do but I must have something incorrect in my mount line
07:30 AM JT-Cave: https://kb.netgear.com/13202/Error-when-mounting-or-adding-ReadyNAS-NFS-shares-in-VMware-ESX
07:31 AM JT-Cave: finally figured out the freaking path to use lol
07:32 AM tiwake[m]: \o/
07:33 AM tiwake[m]: there are more than a few reasons why I don't use netgear products

11:34 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Tube2.jpg
11:34 AM Tom_L: i plan to change the unwrap line so the slots are together
11:37 AM Tom_L: but at least i know that will work
11:39 AM CaptHindsight[m]: https://www.youtube.com/watch?v=ZAQ5ZI1mtKs has their pricing for machining come down recently?
11:52 AM roguish[m]: capt_hindsight[m]: seriously doubt it. always been pricey.
11:54 AM CaptHindsight[m]: a 6 hour drive for me or two days shipped unless you want to pay an extra $100 for a small overnight box
11:55 AM CaptHindsight[m]: maybe their pricing works at 100+ pieces?
12:07 PM Tom_L: CaptHindsight[m], the floor is too clean
12:08 PM Tom_L: all that and no coolant spills?
12:08 PM Tom_L: please !
12:08 PM CaptHindsight[m]: and hardly any machines running
12:08 PM Tom_L: they were too tired after cleaning to run anything
12:08 PM Tom_L: :)
12:09 PM Tom_L: any time 'somebody' comes to my kids work they spend half a day cleaning
12:09 PM CaptHindsight[m]: Jun 17, 2020 ah still during lockdown
12:09 PM CaptHindsight[m]: well posted date, who knows when they shot the video
12:10 PM Tom_L: everybody's harnessed etc and following all OSHA rules too
12:12 PM CaptHindsight[m]: I saw that and wondered what their monthly finance bills look like for just the machine shop
12:12 PM CaptHindsight[m]: 100+ Haas
12:13 PM CaptHindsight[m]: maybe they have a guberment contract to keep half the shop busy 24/7
12:13 PM Tom_L: i wouldn't wanna pay the electric bill alone
12:14 PM Tom_L: the vo'tech here gets haas free for being a haas showroom for them
12:14 PM Tom_L: at least it _was_ that way few years back
12:16 PM CaptHindsight[m]: https://www.youtube.com/watch?v=hDr54x4HEkU from 2017
12:16 PM CaptHindsight[m]: ahh they also have an injection molding plant
12:16 PM Tom_L: yep saw that
12:16 PM CaptHindsight[m]: so they likely keep busy by making their own tools and producing plastic parts
12:20 PM CaptHindsight[m]: quick turn injection molding
12:20 PM Tom_L: i wonder if the 3jaw threads onto the shaft on this dividing head
12:22 PM JT-Shop: mine is bolted on to a face place
12:22 PM Tom_L: yeah but how do you get to the bolts?
12:22 PM Tom_L: i haven't looked that close yet
12:22 PM Tom_L: maybe you can access from the backside
12:23 PM Tom_L: https://www.youtube.com/watch?v=4pZxH3NuLHY
12:23 PM Tom_L: still watching
12:27 PM JT-Shop: mine are hex head bolts
12:29 PM CaptHindsight[m]: "Some of the parts are injection molded zinc alloy. They’re then machined. That cuts costs considerably."
12:33 PM CaptHindsight[m]: looks like a great tool for aluminum, plastics and non-contact applications
12:34 PM CaptHindsight[m]: and as usual from China, take it apart and finish off a few last things to improve it
12:48 PM Tom_L: vactra 2 should be ok inside that you think?
12:50 PM -!- #linuxcnc mode set to +v by ChanServ
12:50 PM Tom_itx: https://www.youtube.com/watch?v=UXhYpDMVi94
12:50 PM Tom_itx: part2
12:50 PM Tom_itx: https://www.youtube.com/watch?v=1g26uWmdk1M
12:50 PM Tom_itx: part3
01:11 PM JT-Shop: mine has grease in it and no oil seals so way lube would leak out
01:11 PM Tom_L: k
01:14 PM JT-Shop: looks like it's time to clean the bandsaw coolant tank now :(
01:32 PM CloudEvil: Threading pulleys on spacex launch tower. https://www.youtube.com/watch?v=mhJRzQsLZGg 200 ton capable Z axis with rapid moves. I think the motors are 5MW.
04:22 PM JT-Shop: Tom_L, in order to disassemble the dividing head you must unscrew the mounting plate with the chuck on it
04:23 PM JT-Shop: looks like there is a video on disassembly
05:02 PM Tom_L: JT-Shop, i just finished cleaning mine and it wasn't nearly as bad as i expected after watching that video
05:02 PM Tom_L: JT-Shop, i posted 3 on taking it apart and back
05:03 PM Tom_L: went back with some good grease instead of oil
05:06 PM JT-Shop: how do you get the chuck mounting plate off the shaft?
05:07 PM Tom_L: right hand thread
05:07 PM JT-Shop: that's good to know
05:07 PM JT-Shop: how did you hold the shaft?
05:07 PM Tom_L: i popped the chuck handle with a nice hammer once and it came right loose
05:07 PM JT-Shop: hmm ok
05:07 PM JT-Shop: with the brake on?
05:08 PM Tom_L: yeah
05:08 PM Tom_L: that little pin
05:08 PM Tom_L: err no the brake
05:08 PM Tom_L: either one would do
05:08 PM Tom_L: the angle locking pin might be the best bet
05:08 PM Tom_L: or both
05:09 PM Tom_L: my timken bearing wasn't bad
05:11 PM JT-Shop: I was afraid of breaking the front dial pin
05:11 PM _unreal_: sigh...
05:12 PM Tom_L: if you puts around with it you could but one good pop will let it loose
05:12 PM Tom_L: just like just about any lathe chuck
05:14 PM JT-Shop: I had to hit it so hard it almost came off and fell on the floor lol but it's off now so the rest should be easy
05:15 PM JT-Shop: all my lathe chucks are D mount
05:15 PM roycroft: i need to fix my lathe
05:15 PM Tom_L: figures :)
05:15 PM roycroft: the parts have arrived
05:15 PM * roycroft looks at the todo list and wonders where he can squeeze that job in
05:15 PM Tom_L: i didn't take the whole main shaft apart like the guy in the video did but i did clean all the greas out real good and tried the bearing
05:16 PM Tom_L: beware there's a ball bearing on the end of the screw
05:16 PM Tom_L: i chased mine across the shop :)
05:17 PM JT-Shop: which screw?
05:17 PM Tom_L: the crank handle screw
05:17 PM Tom_L: part of the backlash & centering of the gear
05:18 PM JT-Shop: mine is stuck to the shaft... maybe that's part of the problem
05:18 PM Tom_L: what is stuck?
05:18 PM JT-Shop: the ball in the end of the crank shaft
05:18 PM Tom_L: just a grease vaccuum on mine
05:19 PM Tom_L: it just rests against the threaded adjustment on the side
05:23 PM JT-Shop: I assume that is to take out any lateral movement in the worm shaft...
05:23 PM JT-Shop: the ball moves but won
05:23 PM JT-Shop: 't come out
05:24 PM JT-Shop: anyway daylight losing time has made my chickens go to roost early so time to retire and stir the chili
05:27 PM Tom_L: air will send it sailing
05:27 PM XXCoder: ugh time change
05:32 PM _unreal_: yep
05:34 PM JT-Shop: not mine and I used an illegal blow off gun lol
05:35 PM _unreal_: I'm telling
05:36 PM _unreal_: JT-Shop, TYPHOON II check it out. they are an amazing blow gun
05:36 PM _unreal_: VERY powerful
05:37 PM * JT-Shop has gone inside to stir the chili
05:45 PM _unreal_: check this out https://drive.google.com/file/d/1rSnMgthLHmecDmOYIU8aunkvmeCG6FNg/view?usp=sharing
05:45 PM _unreal_: its SOOOOOOO small
05:51 PM JT-Cave: https://i.stack.imgur.com/1Wp82.png
05:51 PM _unreal_: JT-Cave, check out that photo I posted
05:51 PM _unreal_: its SOOOOOO tiny
05:52 PM JT-Cave: what is it?
05:52 PM _unreal_: its a stepper
05:52 PM JT-Cave: from a disk drive?
05:52 PM _unreal_: pulled it out of a small camera
05:52 PM _unreal_: it moved the focus lense
05:53 PM JT-Cave: ah the one that moves the lens out
06:00 PM XXCoder: looks like xkcd lol
06:01 PM JT-Cave: what does?
06:01 PM XXCoder: picture you linked to
06:02 PM JT-Cave: ah
06:02 PM XXCoder: https://xkcd.com/
06:02 PM JT-Cave: it was posted on stackabuse
06:04 PM JT-Cave: I thought it was a bit humoris
06:04 PM XXCoder: yeah
06:04 PM JT-Cave: hmm chili with an i is almost done
06:05 PM JT-Cave: we don't eat New York chili... with fillers lol
06:08 PM XXCoder: lol https://xkcd.com/2493/
06:15 PM _unreal_: dont know what I want to do with this micro stepper
06:15 PM _unreal_: but I'm sure I can figure out something cool to do with it
06:16 PM Tom_L: put a rotary on your daughter's cnc
07:35 PM _unreal_: wrong controller on it
07:50 PM XXCoder: andy in here lately?
08:34 PM _unreal_: quiet
08:39 PM Tom_L: great minds are thinking not speaking
08:46 PM Tom_L: skunkworks, how did you set your rotary so it didn't try to home on startup?
08:54 PM skunkworks: I have it set to home automatically where it is when the other axis's are homed
08:54 PM Tom_L: how?
08:55 PM skunkworks: umm...
08:55 PM skunkworks: It just doesn't have a homing velocity?
08:55 PM Tom_L: mine still wants to rotate on start but i do have home sequence set on it
08:55 PM XXCoder: isnt having homing better for repeatbility if power was lost or whatever?
08:56 PM Tom_L: i'll fiddle with it tomorrow. just took it apart and gave it a bath inside
08:56 PM XXCoder: but same times if youre holding something wider than what it can rotate without hitting table homing might be bad
08:56 PM Tom_L: it knows where it started from on startup XXCoder
08:56 PM skunkworks: rotary axis's are kinda hard to have a good homing solution..
08:56 PM Tom_L: i have a home A button and it goes to where it was on boot
08:56 PM XXCoder: cool
08:57 PM XXCoder: skunk I guess fixed encoder would work
08:57 PM Tom_L: but it still wants to move when i home the others
08:57 PM XXCoder: all it needs to is just read out and it knows where it is
08:57 PM Tom_L: i was just trying to avoid adding a home switch
08:57 PM skunkworks: Tom_L: I think you just have zero home velocites. - then if it is in the home sequence - it will just home
08:58 PM skunkworks: I just spent the afternoon trying to get a video card passed through to a vm...
08:59 PM skunkworks: OMG - no wonder people don't want to deal with linux.
08:59 PM XXCoder: dont you need a seperate card for that
08:59 PM skunkworks: yes
08:59 PM skunkworks: I do
08:59 PM XXCoder: and yeah its vm in general thats annoying heh
08:59 PM skunkworks: I wanted to run a windows 10 vm with its own dedicated video card
09:00 PM skunkworks: I finally got it working but now I wanted to download the virtio guest drivers.. Why should it be so hard. like I rememeber downloading an iso... I have spent 20 minutes trying to find it.
09:00 PM skunkworks: it is almost like I have to build it from source? WTF
09:01 PM skunkworks: I might be done for the night.
09:10 PM Tom_L: skunkworks, what about HOME and HOME_OFFSET? are they even in the joint section?
09:58 PM Tom_L: ok all fixed up
09:58 PM XXCoder: yay
09:59 PM Tom_L: i did a button to call MDI_COMMAND = G10 L20 P1 A0
09:59 PM Tom_L: set current position as zero and now it homes right to zero when i push that
09:59 PM Tom_L: and it's not in the regular home sequence
10:00 PM Tom_L: and a HOME axis button to send it to home
10:00 PM Tom_L: which i already had
10:00 PM Tom_L: now
10:00 PM Tom_L: i need to figure out code for the subroutine to send it home the shortest distance
10:01 PM Tom_L: i'll probably just leave it as it is
