12:04 AM elmo40: i wouldn't go so far and say they are trach
12:10 AM elmo40: *trash
12:10 AM elmo40: they are very high priced machines (miller, lincoln, esab...)
12:10 AM elmo40: i know esab has really gone down hill...
12:10 AM elmo40: and they all have 'economy' lines that big box stores sell. stay clear of them.
12:33 AM pink_vampire: any alternative to the thunar file manager?
12:34 AM pink_vampire: when I click open in linux cnc I want something that will allow me to sort the files by date
12:35 AM XXCoder: a second pink
12:35 AM XXCoder: caja
12:35 AM XXCoder: i like it, lean and yes can do what you want
12:36 AM pink_vampire: ?
12:38 AM XXCoder: caja is file manager
12:38 AM XXCoder: you wanted better one right?
12:38 AM pink_vampire: all I'm getting is just scroller from left to right, I can't sort like in explorer in windows.
12:38 AM XXCoder: wheee 2 million covid cases in usa now :(
12:38 AM XXCoder: i dont use windows. ;)
12:39 AM XXCoder: sudo apt install caja
12:39 AM XXCoder: you can then change it to be default file browser
12:40 AM pink_vampire: I'm on debian 7
12:40 AM pink_vampire: without internet
12:41 AM pink_vampire: how do I change the default file manager?
12:41 AM XXCoder: looking up for debian. metalist file i think
12:42 AM pink_vampire: I want to try in on the VM first
12:42 AM XXCoder: sudo apt-get install exo-utils
12:42 AM XXCoder: exo-preferred-applications
12:43 AM XXCoder: that allows you to change 4 programs efaults. one of em is file manager
12:44 AM pink_vampire: what desktop are you using?
12:45 AM XXCoder: xfce mint
12:45 AM XXCoder: its not linuxcnc its my main computer
12:49 AM pink_vampire: piuser@debian:~$ sudo apt-get install caja Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package caja
12:50 AM pink_vampire: XXCoder:
12:50 AM pink_vampire: I can't find caja
12:50 AM XXCoder: hmm maybe package name is different a sec
12:50 AM pink_vampire: this is debian 7
12:50 AM XXCoder: ah common
12:51 AM pink_vampire: I'm trying to do apt-get update
12:51 AM XXCoder: caja-common
12:54 AM pink_vampire: http://ftp.debian.org/debian/dists/wheezy/
12:54 AM pink_vampire: give me 404
12:57 AM pink_vampire: I'm trying to edit the list file with that deb http://archive.debian.org/debian wheezy main
12:57 AM XXCoder: whats you adding?
12:59 AM pink_vampire: wheezy is not supported and the repository become archive :-(
12:59 AM pink_vampire: so I changed the list file to point to the archive
12:59 AM XXCoder: caja should be still currently developed
01:04 AM pink_vampire: I can't find it under wheezy
01:06 AM XXCoder: dunno why
01:14 AM pink_vampire: ok, something very strange.
01:14 AM pink_vampire: I did file > open in the browser, and I got nice menu that allow me to sort. but open in linux cnc give me something with only left and right scroller.
01:14 AM veegee: I use KDE
01:14 AM veegee: and Dolphin
01:14 AM pink_vampire: with linuxcnc?
01:20 AM pink_vampire: here is file > open in the browser and file > open in linux cnc side by side https://i.imgur.com/FJCHBR1.png
01:23 AM XXCoder: dolphin is pretty good. i like caja more
01:25 AM pink_vampire: but why the browser have different "open" window then linux cnc?? there is only thunar on that machine.
01:26 AM XXCoder: you need to change default
01:26 AM XXCoder: ah open some programs has their own version
01:26 AM XXCoder: some just call os libvrary file open, some code their own file open dialog
01:27 AM pink_vampire: do you know what linux cnc use?
01:29 AM XXCoder: not too sure. python file open dialog maybe
01:29 AM XXCoder: which cannot be changed
01:32 AM pink_vampire: I can edit the /usr/bin/axis file if needed
01:34 AM XXCoder: i dont know enough about that unfortunately
01:34 AM XXCoder: you could try qtvcp though thats more modern and editable
01:35 AM XXCoder: JT-Cave have made guide to design your own interface and probably file open too? duynno on latter
01:36 AM pink_vampire: I'm not sure, but sort by date is very basic thing that need to be by default
01:39 AM XXCoder: indeed
01:40 AM pink_vampire: XXCoder: how is that on a commercial cnc machines from you experience?
01:41 AM XXCoder: most dont have sort besides name or o number sort
01:41 AM XXCoder: and in either case there us no way to change sort order :)
01:49 AM pink_vampire: https://www.youtube.com/watch?v=R6PrNylf6_8
01:50 AM pink_vampire: I
01:50 AM XXCoder: interesting
01:50 AM pink_vampire: someone need to tell him about laser..
01:51 AM XXCoder: this can cut anything laser cant
01:51 AM pink_vampire: ok ok, what about water jet?
01:51 AM XXCoder: wet
01:55 AM Deejay: moin
02:29 AM veegee: Hmm copper pipe here isn't that much more expensive than black pipe
02:29 AM veegee: like maybe +30% more expensive. Looks like I can run 1" copper pipe for a hard air line
02:30 AM veegee: And keeping the tank at 200 psi means lower flow required in the tube before the regulator
02:33 AM XXCoder: 30% yeah id go for copper
02:33 AM XXCoder: maybe have water purge before starting the longer lengths
03:56 AM pink_vampire: XXCoder: here?
03:56 AM XXCoder: nah im at my home. whats up heh
03:56 AM pink_vampire: do you know about a cam software for wire banding?
03:57 AM XXCoder: unfortunately nope
03:57 AM XXCoder: i want wire bender machine to play with lol
03:57 AM pink_vampire: what do you want to make with it?
03:58 AM XXCoder: dunno lol
03:58 AM XXCoder: thats why im not getting it :)
03:58 AM syyl: paperclips
03:58 AM syyl: in all sizes
03:59 AM pink_vampire: but the cam is the hard part
04:00 AM XXCoder: i saw pretty interesting small ones before
05:34 AM JT-Cave: morning
05:36 AM XXCoder: yo
06:49 AM Tom_itx: morning
07:54 AM pink_vampire: hi Tom_itx
09:23 AM perry_j1987: morning guys
09:38 AM perry_j1987: any of you guys running amd e350 boards ?
09:53 AM skunkworks: perry_j1987: no. what issue?
09:54 AM perry_j1987: i got a couple of them here i pulled out of a server rack
09:54 AM perry_j1987: was contemplating swapping them for the cnc controllers on my machines
09:55 AM skunkworks: depends on the realtime performance...
10:03 AM perry_j1987: 2.7.15 is out but downloads page doesnt have it?
10:06 AM skunkworks: ?
10:07 AM skunkworks: You can download the livecd and update it accordingly.
10:07 AM perry_j1987: the downloads page for linuxcnc.org is still 2.7.14
10:10 AM skunkworks: they don't make an iso for every release - because you can update to the latest
10:11 AM skunkworks: perry_j1987: what kind of machine? Steppers through the printer port?
10:17 AM skunkworks: (that is why you see the rt_preempt stretch iso is only 2.7.0
10:19 AM CaptHindsight: perry_j1987: being a server board is more of an issues than them using e350's due to the BIOS and a system management controller
10:21 AM CaptHindsight: testing them is the only way to find out
10:37 AM perry_j1987: its not a real server board
10:37 AM perry_j1987: its a gae350n mini itx mobo with 16 gigs of ram
10:37 AM perry_j1987: i just figured it'd be nice to use them for my lathe and 6040 so they were matching
10:38 AM perry_j1987: ok i just pulled one out and got linuxcnc on it and updated it
10:38 AM perry_j1987: base thread says 57276
11:04 AM jymmmm: perry_j1987: I'd suggest flashing them with the latest BIOS
11:05 AM jymmmm: Then clearing the CMOS
11:05 AM perry_j1987: i checked looks like the only bios listed was back in 2012
11:05 AM jymmmm: ah ok
11:05 AM perry_j1987: got it running glxgears, 6 tabs on browser and youtube video and reports 70828 max jitter now
11:06 AM jymmmm: perry_j1987: I've found that if you disable things you aren't using in BIOS it runs better.
11:07 AM perry_j1987: i went through bios and disabled everything
11:07 AM jymmmm: cool
11:10 AM Rab: perry_j1987, which kernel are you running?
11:11 AM perry_j1987: uname -r 4.9.0-12-rt-amd64
11:11 AM Rab: ahh
11:11 AM perry_j1987: lol running that command in terminal shot latency to 74382 haha
11:12 AM Rab: I have a DC7800, latency was very bad in preempt-rt. Much better with rtai.
11:12 AM perry_j1987: the wheezy one?
11:12 AM Rab: Both that, and the experimental rtai kernel for 2.8.0~pre.
11:13 AM perry_j1987: is 2.8 useable or just for playing around
11:13 AM Rab: Over 100000 for preempt-rt, around or below 15000 for rtai.
11:14 AM Rab: It's working for me, but I'm not exactly running a production shop
11:16 AM perry_j1987: what issues have you experienced
12:06 PM perry_j1987: how about in pM :P
12:24 PM skunkworks: probably pot related..
12:24 PM skunkworks: ;)
12:24 PM Tom_L: ok power is back on
12:24 PM Tom_L: yay
12:24 PM perry_j1987: got myself an er32 chuck enroute for my little lathe
12:24 PM skunkworks: Yea!
12:25 PM skunkworks: dad will be so happy - thanks Tom_L
12:30 PM Tom_itx is now known as Tom_L
12:43 PM CaptHindsight: perry_j1987: was logged out, did you get better results than "base thread says 57276" by making BIOS changes?
03:42 PM Deejay: gn8
03:57 PM jymmmm: IF anyone uses google dns servers, this is awesome:
03:57 PM jymmmm: To set a dns server: Edit /etc/dhcp/dhclient.conf ; uncomment line supersede domain-name-servers ( or add this line, if you don't have it ) and list your desired dns servers separated by coma, end with semicolon. It is line 20 of the /etc/dhcp/dhclient.conf. For example, mine looks like this: supersede domain-name-servers 208.67.222.222,208.67.220.220,8.8.8.8; With this option set , I get IP from no matter what access point I conn
03:57 PM jymmmm: ect to, but DNS is same everywhere.
03:58 PM jymmmm: https://askubuntu.com/questions/623704/dynamic-ip-with-static-dns
04:00 PM jymmmm: It's really useful if you use an open AP that uses OpenDNS for site filtering (such as Netflix)
04:14 PM -!- #linuxcnc mode set to +v by ChanServ
05:11 PM CaptHindsight: how does this take to print? https://youtu.be/WrWUssr5nk0?t=90
05:11 PM CaptHindsight: heh, how long
05:14 PM CaptHindsight: looks like ~ 2.5hours
06:06 PM jymmmm: CaptHindsight: 12 seconds
06:07 PM jymmmm: CaptHindsight: MAn, these are the hardest things to search for https://www.amazon.com/16-8V-Charger-Li-ion-Battery-Auto-Stop/dp/B07J38LJVF
06:08 PM Tom_L: it was right there all along
06:09 PM jymmmm: Tom_L: Still need to find 10A
06:17 PM jymmmm: CaptHindsight: It's all your fault (kinda)
06:24 PM CaptHindsight: huh, wut
06:24 PM CaptHindsight: I done understand
06:24 PM CaptHindsight: yes done
06:26 PM Tom_L: wondering about cutting speeds/feeds for a .031 2 flute em in aluminum
06:26 PM Tom_L: max rpm is 4k
06:27 PM Tom_L: chip load .0005" ? .0003" ?
06:33 PM jymmmm: CaptHindsight: you HAD to mention lipo multi stage charging profiles
06:36 PM jymmmm: CaptHindsight: I was almost done with my parts list
06:44 PM * JavaBean goes to pat pat j ymmmm on the back, misses and ends up smacking the back of his head... recovers by pointing out you should maintain a stock of
06:45 PM * JavaBean 'all the things' if you wanna avoid such issues in the future
06:48 PM * jymmmm zip ties JavaBean's beans
06:49 PM jymmmm: JavaBean: I'd become a horder of them, if I could just find the damn things
06:50 PM * JavaBean takes advantage of jymmmm's kindness, lasts a few hours with Mrs. Jymmmm instead of several minutes
06:51 PM JavaBean: that is what lil storage drawers and shelves and boxes are for... i mean, you do know how they store stuff like that in other warehouses, right??
06:51 PM JavaBean: ;p
06:52 PM * jymmmm kindness... Elastration
06:53 PM jymmmm: JavaBean: SEriously, I cna't locate 16.8V 10A charger reasonably
06:53 PM jymmmm: can't find 10A modules either
06:53 PM JavaBean: 16.8 seems a bit odd, why such a number?
06:54 PM jymmmm: 4S lipo cells
06:55 PM jymmmm: The rarity is the low voltage and high charge current
06:56 PM jymmmm: But these cells are 60AH each
06:58 PM JavaBean: have you looked at using something LIKE this here -> https://www.amazon.com/Yeeco-Adjustable-Transformer-Controller-Stabilizer/dp/B07568P3QL/ and setting the output to 16.8?
07:01 PM jymmmm: JavaBean: Yeah, that's a PS, those are easy to find, it's the multi-stage Lipo charging profile that I'm after
07:02 PM jymmmm: JavaBean: https://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
07:02 PM JavaBean: call me crazy, but have you looked into Solar MPPT charge controllers? some are programable to do various *P*S setups. maybe one could do your 4S
07:03 PM JavaBean: without a solar panel, many would just be a "UPS"
07:04 PM jymmmm: I aaaactually have
07:05 PM * JavaBean pulls a bone out of his beard to give it a few minutes of nibbling, before putting it back to comment on jymmmm 'sanity state'
07:07 PM JavaBean: what kind of BMS are you using?
07:08 PM jymmmm: JavaBean: Either a Daly (probably) 4@ 60A or a smart BMS
07:09 PM jymmmm: 4S 3.7V
07:09 PM jymmmm: JavaBean: It's PWM, but... https://www.amazon.com/Renogy-Charge-Controller-Compatible-batteries/dp/B07NPDWZJ7
07:09 PM JavaBean: just a notice, some solar peeps have discovered that the daly BMS's don't always do 'low temp cutoff'
07:11 PM jymmmm: The Daly's dont do and temp stuff, not that I'm aware of
07:11 PM jymmmm: https://www.aliexpress.com/item/32882063870.html
07:12 PM JavaBean: looks like that renology is a hard 12 OR 24 volt system
07:12 PM jymmmm: or https://www.lithiumbatterypcb.com/product/13s-48v-li-ion-battery-pcb-board-54-6v-lithium-bms-with-60a-discharge-current-for-electric-motorcycle-and-e-scooter-protection-2-2-3-2-2-2-2-2-3/
07:12 PM jymmmm: they say lithium, so not sure, would have to RTFM
07:12 PM JavaBean: check the "q and a" section
07:14 PM JavaBean: i recommend going with "separate port" systems, if its a "common port" then if your bms cuts power(low voltage cutoff) you really can't recharge
07:15 PM jymmmm: I was plannign on seperate port, and you just reminded me of why =)
07:15 PM jymmmm: WTF Lithium battery option ready.
07:17 PM JavaBean: remember, its often google translate that does the actual "writing" for the listing. many sellers can't actually read their listing, so there is often bungled "language" used
07:19 PM jymmmm: JavaBean: Document page 06... https://www.renogy.com/template/files/Manuals/RNG-CTRL-WND10%20Manual_V1%EF%BC%8E0_20181130.pdf
07:19 PM * JavaBean hopes his internets lets him see said document
07:21 PM jymmmm: theyre website is SLOW
07:22 PM JavaBean: yay, link worked for me!!!... that battery overcharging feature sounds dangerous for liion
07:22 PM jymmmm: Yeah, kinda scary
07:23 PM JavaBean: that feature, combined with a bms sounds like "things could get interesting"
07:24 PM jymmmm: Just let the BMS kill it off
07:26 PM JavaBean: point being, extra "wear" on both components from the constant battling
07:27 PM jymmmm: oh, maybe huh
07:53 PM Rab: Kind of a wicked rotary stage if a person needed through-spindle action, relatively cheap: https://www.ebay.com/itm/184223522980
07:54 PM Rab: One without the motor stripped, a mere $80 more: https://www.ebay.com/itm/183862294222
07:59 PM Rab: And this is what was mounted, looks like a tiny, right-angle motorized axis: https://www.ebay.com/itm/183789046912
08:00 PM Rab: Maybe if I view seller's other items I'll find the entire machine.
08:45 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/coupler/Coupler1.jpg
08:45 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/coupler/Coupler2.jpg
08:45 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/coupler/Coupler3.jpg
09:12 PM jymmmm: Tom_L: you know about tooling for plastics???
09:13 PM * t4nk_freenode starts to get worried a bit.. I mean.. has _unreal_ been 'involving himself' with high-voltage again orsth? he's been really 'quite' of late
09:13 PM * t4nk_freenode pokes _unreal_
09:14 PM jymmmm: Tom_L: https://www.onsrud.com/articles/O-Flutes-For-Mechanical-Plastics.asp
09:15 PM jymmmm: Tom_L: They work awesome, ask JT-Shop
09:15 PM jymmmm: Tom_L: http://www.plasticrouting.com/
09:16 PM CaptHindsight: for glorious battery charge many times, you can trust us for all volts!
09:17 PM Tom_L: jymmmm, yeah i'm not gonna buy a special cutter just for that
09:17 PM Tom_L: it was a one off part
09:17 PM jymmmm: Tom_L: They are not expensive and do aluminum too
09:17 PM jymmmm: ah ok
09:23 PM Tom_L: i don't use those small cutters that often
09:25 PM jymmmm: no worries
09:26 PM Tom_L: i know onsrud makes good cutters though :)
09:34 PM perry_j1987: hi guys
09:36 PM Choscura: howdy y'all fantabulous motherfuckers
09:41 PM CaptHindsight: perry_j1987: did you try killing power management in the BIOS
09:53 PM flyback: hahaa
09:53 PM flyback: bios hasn't controlled power manage for 20+ yrs
09:53 PM flyback: i've run into a major linux problem
09:53 PM flyback: you can't disable dma anymore

09:55 PM flyback: now I can interface the tiny pins on a sata hard drive or ssd
09:55 PM flyback: to access the uart
09:56 PM flyback: for refurbing via 24 hrs selfscan etc
09:58 PM flyback: man those spindles are complex
09:58 PM elmo40: now now. i was simply sitting here... being a fly on the wall.
09:58 PM flyback: I watched someone give a video on rebuilding it
09:58 PM flyback: and he was splitting hairs literally almost
09:59 PM flyback: BMCC
09:59 PM flyback: SELFSCAN IS A TRUE llf
09:59 PM flyback: rebuilds firmware tracks, smart tracks, translation tables etc
09:59 PM flyback: ev erything escept servo track
09:59 PM flyback: cause that's done by 1 million dollar factory robot
09:59 PM flyback: can't do it on newer drives though :/
