01:18 AM Deejay: moin
02:08 AM miss0r: morning
02:08 AM XXCoder: yo
02:10 AM * Loetmichel designed a cigarette box yesterday and 3d-printed it.. took it from the printer this morning and tried to assemble it: "ok, lets call it 'iterative design'. I forgot to give the hinges enough clearanvce to the case, the stability is sub par, the lock doesent work. :-(
02:18 AM CaptHindsight: you can insert metal hinges into a top down resin printer print
02:19 AM CaptHindsight: while it is printing
02:20 AM Loetmichel: CaptHindsight: the hinges itself work fine... i just inset them into the body of the box... and forget to give the opposite part the clearance for the hinge pins to move
02:21 AM CaptHindsight: now you know
02:22 AM Loetmichel: indeed
02:23 AM CaptHindsight: going to 3d print some battery adapters for cordless tools
02:23 AM CaptHindsight: have to decide on the batteries to use
02:23 AM XXCoder: adopting new batteries to older tools or other way?
02:24 AM veegee: I checked out the Acer 1440G lathe that someone was selling for $6,000 CAD
02:24 AM CaptHindsight: new batts to 10 yo tools
02:24 AM veegee: no wear that I could see
02:24 AM veegee: just paint coming off but doesn't matter
02:25 AM XXCoder: capt nice! because sometimes older tool is better due to having stronger gears or whatever
02:25 AM CaptHindsight: wait wajats the CAN to USD rate again
02:25 AM veegee: that would be $4,500 USD
02:25 AM veegee: cash, no tax
02:25 AM veegee: apparently acer is a decent brand
02:26 AM CaptHindsight: 14 x 40
02:26 AM veegee: no play at all through the entire range that I could tell
02:26 AM CaptHindsight: it's uses the same Chinese casting that many use
02:27 AM CaptHindsight: https://www.mscdirect.com/product/details/80192479
02:27 AM Loetmichel: veegee: acer is a brand that makes decent things... but the product support is abysmal
02:27 AM XXCoder: no crap
02:28 AM XXCoder: dont buy acer tablets ever
02:28 AM veegee: don't care for product support
02:28 AM veegee: XXCoder I don't think it's the same acer
02:28 AM XXCoder: yeah not very likely
02:28 AM veegee: I'm going to see a microweily lathe next
02:29 AM Loetmichel: XXCoder: i have one ;)
02:29 AM XXCoder: so do I. it ended up pretty useless lol
02:30 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14226
02:30 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14415
02:30 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14418
02:30 AM CaptHindsight: https://www.ebay.com/itm/Grizzly-G0709-14-x-40-Gunsmithing-Gearhead-Lathe/274385751992
02:30 AM veegee: The acer 1440G weighs almost 3,000 lbs
02:30 AM Loetmichel: thanks for ebay third party spare parts... no chance to get that display from acer, even offering to pay half the new price.
02:31 AM veegee: that's a pretty decent weight
02:31 AM Loetmichel: "send it in get it repaired for 90% of new price"
02:31 AM XXCoder: thats acer for you
02:31 AM XXCoder: however
02:31 AM XXCoder: i wonder if you could find another display with same connector type
02:31 AM veegee: 3,000 lbs for a 14x40 lathe is on the heavier side, should be rigid
02:31 AM XXCoder: then 3d print a case for it
02:31 AM veegee: CaptHindsight also I thought Acer used taiwanese castings
02:31 AM Loetmichel: ... "hey that thing is 3 weeks old and thats not from dropping but from one of your guys embedding debris between front glass and LCD..."
02:31 AM Loetmichel: "we dont care, have fun with the product"
02:32 AM XXCoder: jeez
02:33 AM XXCoder: what model is yours?
02:33 AM Loetmichel: cant remember
02:33 AM XXCoder: i'd send you mine but shipping probably not worth it heh
02:33 AM XXCoder: my tablet has kinda broken usb port
02:40 AM CaptHindsight: vertical lathe https://detroit.craigslist.org/okl/tls/d/lima-leblond-lathe/7128398677.html
02:40 AM Loetmichel: ah
02:40 AM CaptHindsight: https://detroit.craigslist.org/mcb/tld/d/warren-leblond-lathe-14-48/7128519547.html
02:40 AM Loetmichel: Acer Iconiy B1
02:40 AM Loetmichel: Iconia
02:40 AM Loetmichel: @ XXCoder
02:40 AM XXCoder: not quite same then. mine is iconia 840 fhd
02:40 AM Loetmichel: 10" cheap tablet back in 1016 or so iirc
02:40 AM XXCoder: it has intel cpu. useless at 1.4.4 which it is at. they refused to update
02:40 AM XXCoder: nice. pre-colonization of america tablet
02:40 AM XXCoder: ;)
02:42 AM CaptHindsight: PCIe x4 jus add Mesa card
02:43 AM Loetmichel: yeah, for $300 you get a decent intel/amd notebook with way better data all over the board
02:43 AM Loetmichel: i didnt say its expensive per se
02:44 AM Loetmichel: i said its (in my opinion) not worth the price
02:44 AM CaptHindsight: if you want all open source
02:45 AM CaptHindsight: wish they just used ddr3,4 SIMMS vs soldered in
02:45 AM CaptHindsight: SO-DIMM
02:47 AM veegee: I have a FIRST LC 1-1/2 VS mill and I love it
02:47 AM veegee: if the Acer is similar in quality, I'm totally fine with that
02:47 AM veegee: the First mill has taiwanese meehanite casting though
02:47 AM veegee: have to do some research on the acer
02:47 AM CaptHindsight: what other options do you have if you need it now?
02:51 AM veegee: I don't need it right this minute, but I've been searching for a month and this and the potential microweily are the only two decent ones I came across
02:51 AM veegee: lathes are much harder to find than vertical mills
02:53 AM veegee: The microweily is $7,000 but apparently the guy's boss wanted to keep it and not sell it. If I can convince him to sell it, I'd rather get that one
02:54 AM veegee: Although I really c ouldn't find a single fault with this acer lathe. Looks barely used to be honest
02:56 AM veegee: Might widen my search radius actually to neighbouring provinces and make a road trip out of it
02:58 AM veegee: CaptHindsight how do you reckon they're chinese castings? I can't find any reference to that on the internet. All the references I f ound state that it's a taiwanese machine
02:59 AM CaptHindsight: maybe they copy the same casting
02:59 AM CaptHindsight: it's just like an Emco i had
03:01 AM CaptHindsight: Enco
03:03 AM veegee: "ACER is an industrial equipment manufacturer based in Taiwan with two US facilities. They are a leading manufacturer of a wide variety of machining equipment such as vertical machine centers, CNC bed/knee type mills, precision manual mills, surface grinders and engine lathes. ACER ensures premium quality machines while GMB ensures premium service."
03:03 AM veegee: Definitely not chinese
03:24 AM veegee: Theres also this hardinge lathe: https://www.kijiji.ca/v-power-tool/ontario/hardinge-lathe/cas_12433157?channelId=101&td=QB1fXgb8p5f69jNTzUcd8q6I-pC54uJACCEg5uSWUZQkt2t-l36mJFB-RHZeIOGxJFuC8JdCG802NQh6j2RfTa82xwBnkmP4esunoNpH3aFB8-lBCLitv6SdgLrLuu_LqTKGm3J33OC4Utzf0RuBuArOtB5K9-Byv3GW1fu2btuak_ii7jJnuMUadwUAAbGwlsRiPNsc5EQUhcsiOg7EV4owIDderLehJfb5UqnRpH0kSUPlFlekQoZVPUBFjyqiWFkG-OD48udLmKcbJcptTxBa1cyoJ5Gri

03:25 AM veegee: ignore that. Hardinge lathe: https://tinyurl.com/y77oedm9
03:26 AM XXCoder: heh thats monster of a url
03:27 AM XXCoder: i dont think i see a ? so it cant be trimmed
03:27 AM XXCoder: ah i see it
03:30 AM sensille: wow, is that a realistic price?
03:31 AM veegee: What do you m ean? That's what he's asking for it
03:31 AM veegee: I can negotiate
03:33 AM veegee: There's also this 19x80 lathe for $6,000
03:33 AM veegee: https://www.kijiji.ca/v-power-tool/woodstock-on/standard-modern-engine-lathe-for-sale/1477934170
03:33 AM veegee: Too big for me, don't need 80" bed
03:34 AM sensille: i'm just astonished how much these things cost. it was an honest question
03:34 AM veegee: New ones go for 20-40k
03:34 AM veegee: With DRO and all that stuff
03:34 AM veegee: They're precision machines
03:35 AM veegee: That's why f inding a good used one is difficult.
03:35 AM veegee: I don't mind payint $6k for one in good shape with minimal wear
03:35 AM sensille: i see
03:38 AM veegee: You can also get one for like $1,000
03:39 AM veegee: but it's going to be old, worn, and just generally shitty
03:39 AM veegee: it'll work
03:39 AM veegee: but it'll be old and worn
03:39 AM veegee: old is fine. Worn is not fine
03:39 AM XXCoder: depends on why
03:39 AM veegee: I'm looking for one that is not worn and has a DRO
03:39 AM veegee: so naturally have to increase budget
03:39 AM XXCoder: could use worn one for parts for one, if you have better machine
03:40 AM XXCoder: or maybe youre looking for full restore - you redoing ways so on
03:40 AM XXCoder: me, i rather get reasonable condition one if i want a machone.
03:42 AM veegee: Redoing ways is not part of what I want to do right now
03:42 AM XXCoder: indeed
03:42 AM veegee: I need a machine that works to start with
03:42 AM veegee: I can fix anything except for the ways
03:43 AM XXCoder: wasnt suggesting you to :D just listing ponental reasons one would want shot machine
03:44 AM veegee: I really wish I could tempt that one guy to sell me his microweily 16x50
03:44 AM veegee: He listed it for sale and then changed his mind
03:44 AM veegee: Now have to figure out a way to change his mind back
03:44 AM veegee: He listed it for $7,000. I would have bought it on the spot
03:47 AM XXCoder: drat
03:48 AM veegee: It weighs 4,000 lbs
03:48 AM veegee: Perfect. I can transport it easily and my forklift will pick it up no problem
05:36 AM JT-Cave: morning
05:38 AM JT-Cave: 73°F high of 70°F
06:26 AM Tom_L: morning
06:26 AM Tom_L: 60F
06:30 AM JT-Cave: 71°F now
06:34 AM JT-Cave: gotta set some 4x4 posts today
06:45 AM Tom_L: another chicken run?
06:51 AM JT-Cave: yea for the Cinnamon Queens
06:51 AM JT-Cave: they really need to get outside and play
06:51 AM JT-Cave: they are 6 weeks old today
07:12 AM Choscurano is now known as Choscura
08:53 AM Loetmichel: soo, finally got the 4 ender3 3d-printers set up in their corner and printing... single missing thing now is the Lan controlled power strip that i ordered... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17850&g2_imageViewsIndex=1
09:09 AM skunkworks: they are renaming raspbian
09:09 AM skunkworks: Exctiting times.. ;)
09:10 AM * JT-Shop has got his dirt out of one hole... 2 more to go
09:15 AM Rab: "Raspberry Pi OS", how much did they pay someone to come up with that?
09:16 AM Rab: I wonder if it's branding flexibility to move away from Debian.
09:16 AM Loetmichel: probably
10:53 AM dirty_d: https://www.youtube.com/watch?v=TkqT-P9pxek
10:53 AM dirty_d: if it looks stupid and it works, it's not stupid
10:54 AM jymmmm: Loetmichel: What, you forgot how to use serial port on the lan power strip?
10:56 AM Loetmichel: jymmmm: i have ordered one. Yet to be delivered
10:57 AM Loetmichel: the power strip i use now is dumb, sad as that is ;9
11:00 AM jymmmm: dirty_d: that's pretty good =)
11:01 AM jymmmm: Loetmichel: lol, you are just lazy to reach over and flip the switch =)
11:03 AM jymmmm: Loetmichel Funny thing, most don't support SSH, just telnet.... Joos be H@x0r3d
11:04 AM jymmmm: Loetmichel and dont forget to program it to reset at midnight ;)
12:01 PM bmbbsr: Hi who ever is here ;-)
12:02 PM bmbbsr: pcw_home, Sir are you working
12:03 PM bmbbsr: @ all someone from the Managment / Programmer here ?
12:03 PM bmbbsr: many People are strugeling as the 2.9 Axis Sm examples wont work anymore
12:05 PM bmbbsr: Just look at the Form posts today 4treads on the error
12:05 PM pcw_home: we are working 1/2 time
12:05 PM bmbbsr: 10:am havetime we got finished as 7Pm
12:06 PM bmbbsr: pcw_home, Sir may i ask if you coudt repair the 7i76e from the Education Center
12:08 PM pcw_home: it was unrepairable (looks like some voltage higher than 3.3V got applied to all internal parts)
12:08 PM bmbbsr: Bad news
12:09 PM pcw_home: the EThernet chip was bad, so I removed it ,tha removed the 3.3V short but literally all the 3.3V parts were bad
12:09 PM bmbbsr: so what is the next step
12:09 PM pcw_home: we can send you a functional but unsaleable replacement
12:10 PM bmbbsr: its not for sale the machine needs this
12:10 PM bmbbsr: or did i missunderstand unusable
12:11 PM pcw_home: it must have been damaged by a stray wire contact or wrong connection to one of the parallel expansion ports
12:11 PM pcw_home: unsaleable (ugly, patched etc etc)
12:11 PM bmbbsr: the wrong soldering i showed you may have bridged all this powerline
12:12 PM pcw_home: yeah why and where that happened I do not know, it did not leave Mesa that way
12:12 PM bmbbsr: pcw_home, will it be usable for a 5axis machine setup
12:13 PM bmbbsr: no extras only the internals
12:13 PM pcw_home: every think works I think it has a patch on the back of the card
12:15 PM bmbbsr: ok THANK you the principal has his last week in the center but i guess the next one will find somone to give it
12:15 PM bmbbsr: the Center got 10.5k Stundens 350 Thatchers not easy to find the right place
12:17 PM bmbbsr: pcw_home, if it is posible i dont know what the letter says you recived with write ((z.h Stumpf ))on the return
12:18 PM pcw_home: OK Ill make a note of that
12:18 PM bmbbsr: Than you very mutch again for the offer and the Time you invested
12:19 PM bmbbsr: maybe then the machine will move in Jan 2021
12:20 PM bmbbsr: pcw_home, did you see the Stitching Embroid CNC we build from 50USD junk
12:23 PM pcw_home: Yes, that's neat
12:24 PM Loetmichel: Jymmm: the lan power strip is just so that i can remotely shutdown the printers in case of fire or "why did someone print on a friday evening and let it running all weekend??"
01:05 PM jymmmm: Loetmichel: Oh, in that case, can I make a suggestion....
01:05 PM Loetmichel: i am all ears
01:07 PM jymmmm: Loetmichel: Contact a fire extinuisher company and get an attic heat sensor. Wire that to a safety relay, so that it kills power, and potentially sound an alarm, Also, if you have nitrogen tanks, you cna wire it in to use the nitrogen to extinguish the fire, it's very effective at displacing the oxygen.
01:07 PM jymmmm: Loetmichel: I have a white papr on using nitrogen as a halon alternative
01:09 PM jymmmm: Loetmichel: You can enclose your printers and just flood the compartment with nitrogen if a fire breaks out
01:09 PM jymmmm: Loetmichel: It's what laser manufacturers are doing now
01:09 PM Loetmichel: that would be seriously overdoing it
01:09 PM jymmmm: well, not the nitrogen, just killing power
01:10 PM jymmmm: Loetmichel: Well, fire is fire, killng power doens't put out any fire.
01:10 PM Loetmichel: it doesent fire it on either
01:10 PM jymmmm: ?
01:11 PM jymmmm: Loetmichel: I've been thru the worse woldfire in California history, I'm a little more sensative to it.
01:12 PM Loetmichel: i meant: its not heating up the fire even more, giving it more molten plastic to eat if i cut the power.
01:14 PM jymmmm: Loetmichel: It only takes 90 seconds (she went to sign for a package at the front door) to turn a $30,000 laser into this... https://i.imgur.com/3XLHedY.jpg
01:15 PM jymmmm: just saying =)
01:15 PM Loetmichel: that looks "done"
01:16 PM jymmmm: She had been running parts all morning, no problems. UPS knocked on the door, she was gone 90 seconds and that's what she came back to
01:16 PM Loetmichel: yeah, its more for insurance reasons than any real danger
01:16 PM Loetmichel: because the printers run unattended often enough tru the night
01:18 PM Loetmichel: i AM thinking about getting a couple of those "fire extinguisher bombs" that you mount above a fire hazard and that explode and spread baking soda powder all over the surroundings
01:18 PM jymmmm: Yeah, just offering a simple solution. those attic heat sensors are rated like 160F, 180F, etc, so would clearly detect a fire
01:18 PM jymmmm: Loetmichel: oh, those are bad and have been outlwed for like 40 years.
01:19 PM Loetmichel: mabe in the US. IIRC they are still allowed in germany
01:20 PM jymmmm: Loetmichel: From NIST.gov... https://www.nist.gov/system/files/documents/el/fire_research/R0000296.pdf
01:20 PM jymmmm: Loetmichel: You know NIST, same people how developed linuxcnc =)
01:20 PM jymmmm: who*
01:21 PM Loetmichel: i cant see the relevnce to the powder extinguishers at all
01:22 PM jymmmm: Fuck BC powder, it's corrosive anyway (it's more that just baking soda btw)
01:23 PM jymmmm: I like CO2 extinguishers if you couldn't tell =)
01:52 PM andypugh: Rab: Are you saying that you are using 4.14.174-rtai extensively with no problems in normal use, or that you don’t see any problems with LinuxCNC and the generally-distbuted kernels?
01:53 PM andypugh: Rab: Also, which script? The insmod-only one or a runtests one?
02:02 PM andypugh: Jymmm: I quite like the sound of BC Powder: https://www.skiclub.co.uk/ski-club-holidays/bc-powder-adventure
02:23 PM Rab: andypugh, not extensively, but frequently invoking LinuxCNC 2.8.0-pre under 4.14.174-rtai to test a machine under construction. I used this script: https://pastebin.ubuntu.com/p/7hgtP9P2WM/
02:24 PM andypugh: OK, that’s rather interesting as it takes many tens of thousands of iterations for that to crash my machine,
02:24 PM andypugh: Whereas the runtests varaint crashes in the sorts of iteration counts that you mentioned.
02:26 PM andypugh: Rab: Do you have a stock LinuxCNC, or do you compile from source?
02:27 PM andypugh: This one: https://pastebin.ubuntu.com/p/wj8pMZsfyG/ needs the tests folder, you see, and I am nit sure that exists on a normal install.
02:28 PM Rab: andypugh, I used the packages from http://www.linuxcnc.org/temp/, although I believe what I used is older than what's available now.
02:29 PM andypugh: Ah, yes, you might have missed a few improvements. I do think we have made it better.
02:29 PM Rab: andypugh, right, no linuxcnc-dev here, so I couldn't run the runtests script.
02:29 PM andypugh: No worries.
02:31 PM Rab: andypugh, I'll upgrade to the newer packages when I get a chance and try the loader script again.
02:32 PM Rab: I was started by the low number of passes. I thought I would have to let it run overnight.
02:34 PM Rab: No idea if any of this is useful, but I thought I'd try for a datapoint since I was running 4.14.174-rtai.
02:34 PM CaptHindsight: Rab: sorry was logged out, https://pastebin.ubuntu.com/p/7hgtP9P2WM/ gave you what results?
02:35 PM andypugh: The package in /temp is from 22/4. And there was an RTAI change on 9/5 so I will make and upload a new version.
02:35 PM Rab: <Rab> andypugh, I just ran your test five times on a Core2Duo with 4.14.174-rtai. It locked up at passes 353, 71, 32, 1156, and 148. 1156 was odd; the script stalled, the GUI was still responsive, but most things I tried didn't work. I think it killed disk access.
02:35 PM jymmmm: CaptHindsight: I think I found a solution to my dual-fuse scenario... https://www.amazon.com/ZOOKOTO-Circuit-Trolling-Terminal-Inverter/dp/B071XTNLT5
02:35 PM Rab: I downloaded these packages on 22/3.
02:37 PM Rab: CaptHindsight, see paste above.
02:39 PM Rab: This is on a Wheezy LinuxCNC install which was upgraded to Buster.
02:40 PM jymmmm: Rab: MAybe unrelated, but on the C2D, did you use the onboard video or an addin video card?
02:41 PM Rab: jymmmm, using Intel onboard video, but X.org doesn't recognize it and uses VESA modes.
02:42 PM andypugh: OK, there is a later version of RTAI in /temp now
02:43 PM jymmmm: Rab: do you have ANY other video card you can use/beg/borrow/steal just to test?
02:43 PM andypugh: (will work with the same kernel and LinuxCNC, I think.
02:43 PM andypugh: Jymmm: Video is a red herring here, I think.
02:44 PM Rab: jymmmm, alas, I do not.
02:45 PM Rab: Latency figures look good though (IMO).
02:45 PM andypugh: I am gettting 3-digit latency
02:47 PM jymmmm: Rab: Maybe this might help... https://askubuntu.com/questions/1103827/ubuntu-18-04-does-not-recognize-intel-graphics-card-after-update
02:47 PM andypugh: (unlil I open a web browser or similar, it’s up abouve 1500 then)
02:48 PM Rab: Heh heh, low 5-digit for max jitter here. Same as under Wheezy.
02:48 PM Rab: jymmmm, thanks!
02:49 PM Rab: andypugh, thanks for the updating the packages, downloading.
02:54 PM jymmmm: Rab: Jsut be sure to backup your files before editing them; cp filename filename.yyyymmddhhmm =)
02:54 PM Rab: jymmmm, ya mon
02:54 PM jymmmm: Rab: Can't tell you how many times that's saved my wallet from tequilia and asprin =)
02:54 PM FinboySlick: jymmm: You're so mild. I at least expected hookers and blow.
02:55 PM jymmmm: hahahahaha
02:55 PM Rab: jymmmm, bonus points for ISO date instead of filename.new, filename.old, filename.older, filename.oldest, filename.good, filename.works.
02:55 PM CaptHindsight: jymmmm: midget sex workers to be PC
02:57 PM jymmmm: Rab: Yeah, cause oyu never know how many times you might need to be editing the file till you get it right, and you cna look back to old revisions. But sometimes I will do cp filename filename.ORIGINAL just so I can distinuish bewtween them all.
02:57 PM andypugh: maybe petite sex workers? Or just “workers” to remove nearly all potenitally pejorative terms. Except what if they are unemployed? “beings” is probably the safe option.
02:58 PM jymmmm: CaptHindsight: You have to be political to be politically correct, and I prefer to have freaky midget hookers, not PC one's tyvm =)

03:00 PM jymmmm: 76M views, wow!!!
03:01 PM CaptHindsight: jymmmm: reminds me of an old dating personal that was similar to" Seeks heavily tattooed piercing fanatic with a penchant for covering lovers in sour cream and gravy. NO FREAKS!
03:01 PM jymmmm: LMAO
03:03 PM FinboySlick: jymmm: I was like: Wait, that's not MC Hammer.
03:03 PM jymmmm: FinboySlick: It's Rick James Biotch =)

03:12 PM CaptHindsight: was looking for small linear rails: http://www.ikont.eu/jp/eg/product/tech/tech03.html
03:14 PM jymmmm: CaptHindsight: WAY too big
03:15 PM jymmmm: damn those are small, they better have free shipping!!!!
03:16 PM jymmmm: wait, what are the mount holes using for bolt threads?
03:18 PM jymmmm: CaptHindsight: Circa 2012 (bottom of that page)
03:22 PM CaptHindsight: jymmmm: they mount through the sides vs top
03:23 PM CaptHindsight: I think the 2mm mounts via the top/bottom
03:23 PM andypugh: I want the opposite, a huge stroke rotary bushing
03:23 PM andypugh: cheap.
03:24 PM CaptHindsight: the 1mm carriages are more narrow than the 2mm but the 2mm are lower profile
03:25 PM CaptHindsight: andypugh: what dia rail?
03:26 PM andypugh: I think I found one that is cheap enough but _too_ big :-)
03:26 PM andypugh: https://www.ebay.co.uk/itm/264518372411
03:28 PM CaptHindsight: hunk of machined plastic will cost more new
03:30 PM andypugh: I want to make a CNC slotting head for my mill. One with servo-rotation of the cutting head.
03:31 PM andypugh: But a 90mm slide would be mich bigger than necessary
03:32 PM andypugh: Though I vuess it coud be the rotor of a coaxial brushless servo, for maximum wierd points
03:32 PM andypugh: Hmm, make an outrunner with longer than normal magnets…..
03:33 PM Deejay: gn8
03:33 PM andypugh: Position encoder is a problem with that otherwise flawless plan.
03:39 PM CaptHindsight: andypugh: did you post this on the forums or ML, this sounds familiar?
03:40 PM CaptHindsight: will look later, just heading out
03:51 PM jymmmm: CaptHindsight: woohoo 100A https://www.amazon.com/STETION-Resettable-Circuit-Overload-Protection/dp/B07FFB63LK
03:53 PM jymmmm: That'll save from buying a disconnect switch too
04:09 PM jymmmm: HEy cool... Induction Heater.... https://www.amazon.com/Yosoo-Voltage-Induction-Heating-12V-48V/dp/B01C70G7Y8
04:12 PM Rab_: rebootsb15[k0d
04:13 PM jymmmm: Rab_: I hope that's not a password =)
04:13 PM Rab_: Not any more. -_-
04:13 PM Rab_ is now known as Rab
04:14 PM jymmmm: lmao
04:28 PM andypugh: Jymmm: Cheaper on eBay, And they do work,
04:30 PM jymmmm: andypugh: Ah, nice. Always though induction heating was cool, if I was forge welding steel rod, I'd probably get one
04:31 PM jymmmm: Or cattle branding
04:31 PM andypugh: This is my auction. I wonder what I will get? https://www.ebay.co.uk/itm/Weber-Carburettor-Jets-x72-Tuners-Set/114250877482
04:32 PM andypugh: Already higher than I expected
04:33 PM jymmmm: I really HATE that ebay makes the seller's description of a framed window
04:33 PM jymmmm: in a*
04:34 PM jymmmm: IT's like they are upselling everyone's else's stuff, and minimalizing the seller's item
04:34 PM jymmmm: PINKY
04:35 PM pink_vampire: jymmmm: !!!
04:49 PM skunkworks: the spindle pully is plastic on the emco..
04:49 PM skunkworks: suprised the heck out of me.
04:49 PM andypugh: Probably good enough.
04:49 PM skunkworks: (it isn't round)
04:49 PM andypugh: Probably not good enough
04:50 PM skunkworks: heh
04:51 PM Tom_L: how many parts on an auto used to be metal that aren't now?
04:53 PM paul303: Hi I´m new here. Have some noob questions
04:54 PM Tom_L: ask away
04:55 PM infornography: rounds pulleys are over rated
04:57 PM paul303: Just installed Linux CNC 2.8 on Debian 9 together with mesa 7i76e. Working so far, but i´ve the problem that the motors are stuttering when i use the keyboard. If I´m using the onscreen buttons everythings fine. Any ideas?
04:58 PM Tom_L: steppers or servos?
04:58 PM paul303: steppers
04:58 PM paul303: no mechanics, just the drives with steppers to test
04:58 PM Tom_L: stepper timing
04:59 PM Tom_L: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Drive_Timing
05:02 PM paul303: I´m using cheap TB6600 drives.
05:03 PM Tom_L: http://linuxcnc.org/docs/html/config/stepconf.html
05:05 PM paul303: thank you Tom
05:08 PM paul303: my values are: step on: 5000, step space: 5000, direction hold: 10000, direction setup: 10000
05:18 PM jymmmm: infornography: triangle pulleys are the bomb
05:29 PM CaptHindsight: paul303: "the motors are stuttering when i use the keyboard"
05:30 PM CaptHindsight: paul303: " If I´m using the onscreen buttons everythings fine."
05:31 PM jymmmm: Sounds like USB polling
05:31 PM CaptHindsight: paul303: how are you using the keyboard? Typing in G-code moves?
05:32 PM CaptHindsight: trying to understand what he is comparing
05:33 PM jymmmm: CaptHindsight: He's using a mesa board too, sounds weird
05:33 PM CaptHindsight: stepper pulse timing would be the same no matter how the G-code gets entered or if jogged with the GUI, unless he's moving to fast for his thread timing
05:34 PM jymmmm: But says if he uses touch, no problem.
05:34 PM CaptHindsight: not sure yet what he is comparing
05:35 PM paul303: try to explain:
05:35 PM jymmmm: Think this pump would squirt a cat 8ft away? https://www.aliexpress.com/item/32838824379.html
05:35 PM paul303: if i´m using the gui the motors work fine
05:35 PM CaptHindsight: but if stepper pulse timing configs fixes it , great!
05:35 PM jymmmm: paul303: What mobo are you using?
05:36 PM paul303: mobo=motherboard?
05:36 PM jymmmm: paul303: How many USB devices do have plugged in?
05:36 PM jymmmm: yes, mobotherboard
05:36 PM paul303: usb mouse and usb keyboard, nothing else
05:37 PM jymmmm: and how is the touch screen connected?
05:37 PM paul303: no touch screen
05:37 PM paul303: just plain vga
05:38 PM jymmmm: oh, you mean using the mouse and screen controlls?
05:38 PM paul303: motherboard i dunno, it´s an old hp 7900 with core 2 duo E8400
05:39 PM jymmmm: paul303: Try using the keyboard with the mouse unplugged, Do the motors still stutter?
05:39 PM andypugh: paul303 Hmm. if you start LinuxCNC from the command line, does it say “using POSIX realtime” or something else?
05:40 PM paul303: without mouse no change
05:40 PM paul303: i use the realtime kernel
05:40 PM jymmmm: https://www.amazon.com/HP-Compaq-dc7900-3-0GHz-Desktop/dp/B001NIKA08
05:41 PM jymmmm: paul303: Do you happen to have a PS/2 keyboard by chance?
05:41 PM paul303: yes the amazon link is right, thats my pc
05:42 PM paul303: only usb to ps/s2 adapter
05:43 PM jymmmm: paul303: Eh, try it in the purple socket instead of the USB socket
05:43 PM Tom_L: purple matters?
05:44 PM jymmmm: Tom_L: Sadly, yes. PEr the PS/2 specs, but in reality, not really =)
05:44 PM paul303: keyboard doesnt work, do i have to reboot?
05:44 PM jymmmm: Tom_L: Purple Sockets MAtter
05:45 PM jymmmm: paul303: no, it should just work. no biggy was jsut a test.
05:45 PM Tom_L: did he pass?
05:45 PM jymmmm: paul303: but if you don't mind rebooting, we cna try
05:45 PM paul303: rebooting
05:46 PM jymmmm: Tom_L: Those usb to ps2 adapters are half crap
05:46 PM paul303: keyboard doesnt work with this adapter
05:46 PM Tom_L: jymmmm, i'm sure
05:46 PM jymmmm: paul303: IT's all good, maybe plug the kybd into a different USB socket?
05:47 PM paul303: maybee i need a purple one this green adapters dont work
05:47 PM paul303: tested three of them
05:47 PM jymmmm: nah
05:48 PM jymmmm: Unless they are all crap, dont worry about it, Forget the adapter, just try a different USB port
05:48 PM paul303: different usb trying
05:49 PM paul303: same here
05:49 PM paul303: do i need a decent pc?
05:49 PM jymmmm: paul303: Go into the BIOS, and see if legacy USB kayboard is enabled?
05:49 PM jymmmm: Those are nice PC's
05:53 PM paul303: there is no legacy setting in bios
05:54 PM skunkworks: anyone know the power an xl belt can handle?
05:55 PM Tom_L: skunkworks, https://www.sdp-si.com/PDFS/Technical-Section-Timing.pdf
05:56 PM paul303: anyway: i have to leave now, thank you for support. If you have any ideas to solve this pleas leave me a message at kaffeemitwurst@hanning-home.de
05:56 PM jymmmm: paul303: here's the manual if you care... https://images10.newegg.com/User-Manual/User_Manual_83-147-218.pdf
05:56 PM jymmmm: has DIMM stuff in it
05:57 PM Tom_L: skunkworks, there are different widths
05:57 PM skunkworks: Tom_L: I get that - but it say .08hp at 1000rpm if I am reading it right
05:58 PM Tom_L: poly, kevlar etc
05:58 PM paul303: bye and thanx
06:01 PM Tom_L: that's what fig 6 shows
08:56 PM flyback: tornado heading here
08:56 PM flyback: been nice knowing you guys
09:01 PM pink_vampire: flyback: what machine do you have?
09:38 PM Tom_L: on a G53 can G00 preceed it or does it have to come after it? : G00 G53 instead of G53 G00
09:38 PM Tom_L: it says 'program on the same line as a linear move'
09:38 PM XXCoder: yo
09:39 PM Tom_L: working on my post a bit
09:40 PM W1N9Zr0: http://linuxcnc.org/docs/html/gcode/overview.html#_g_code_order_of_execution
09:41 PM Tom_L: doesn't say
09:42 PM W1N9Zr0: order on the line doesn't matter
09:42 PM Tom_L: thought so, wanted to verify
10:11 PM -!- #linuxcnc mode set to +v by ChanServ
10:11 PM cradek: Tom_L: it doesn't matter. your error is not from that.
10:19 PM Tom_L: i wasn't getting an error, just working on my cad cam post a little
10:19 PM Tom_L: but thanks for verifying that
10:43 PM veegee: Does the "swing over bed" of a 14x40 lathe mean that the diameter is 14"?
10:43 PM veegee: So the distance from the center to the bed is 7"?
10:48 PM Tom_L: yes
10:48 PM Tom_L: 14" diameter
11:07 PM veegee: I checked out the Acer 14x40 lathe in person and everything was nice and smooth and tight
11:07 PM veegee: Original price was around $20k, he's selling it for $6,000
11:07 PM veegee: I'm very tempted to buy
11:08 PM veegee: Couldn't detect any wear, smooth throughout the range of the bed
11:08 PM veegee: It also has automatic oiling and a coolant pump and pretty much ready to use
11:09 PM veegee: Plenty of other older lathes in the area for like $3,000 CAD but they need some work to restore whereas this one is ready to use as soon as you power it on
11:40 PM elmo40: veegee: in Canukistan, eh?
11:40 PM veegee: yeah
11:40 PM elmo40: same
11:40 PM veegee: Any thoughts on this lathe?
11:41 PM veegee: It's a DSG 15x35
11:41 PM elmo40: you have a link?
11:41 PM veegee: 15x36
11:41 PM veegee: https://tinyurl.com/yb7kvbmq
11:42 PM veegee: Right now the one I'm planning to buy is an Acer E-lathe 15x40V
11:42 PM veegee: unless something better shows up
11:42 PM veegee: 14x40*
11:42 PM elmo40: i know that guy
11:42 PM elmo40: been to his place a few times
11:42 PM elmo40: just cleans them up and paints them. any defects are still there... but with a higher price.
11:43 PM elmo40: i bought a MIG welder from him. big mistake. was missing the damn drive rollers!
11:43 PM elmo40: had to go back and get them.
11:43 PM veegee: Yeah that's what I figured
11:43 PM veegee: This is the one I saw in person yesterday: https://www.kijiji.ca/v-view-details.html?adId=1505135056
11:44 PM veegee: Well the 14x40 model
11:45 PM veegee: elmo40 go to everlast for your welders
11:45 PM veegee: I have their powertig 325 and it's excellent
11:45 PM veegee: I made measurements using my lab equipment and they're spot on with the specs
11:45 PM veegee: Very good machines for the price
11:46 PM roycroft: i have a powertig 250ex and i love it
11:46 PM * JavaBean grumbles, even canuckdians have better options for local equiptment than me
11:47 PM roycroft: more importantly, i have friends who do welding for a living who have used mine and they think it works great and are surprised that it works so well for being so inexpensive
11:48 PM veegee: It's priced well. other companies are just overpriced
11:48 PM veegee: it's not a complicated machine
11:48 PM veegee: it's pretty much just an IGBT current source
11:48 PM veegee: Miller is trash
11:49 PM veegee: same with lincoln electric
11:49 PM * JavaBean gasps
11:50 PM veegee: Well this is the Toronto area, the biggest city in Canada
11:50 PM veegee: so if anything is going on in Canada, it's in this area
