02:58 AM Deejay: moin
03:06 AM pink_vampire: hi Deejay
03:34 AM imrija: Hi, I'm seeking help with setting up my mesa 5i23 and linuxcnc machine. I would be grateful for any suggestions!
03:34 AM pink_vampire: i'm with lpt
03:35 AM imrija: I've already plugged my 5i23 to computer and connected my servo card and I/O board too. I connected one of my linear scales to ENC0 header on the servo board
03:35 AM imrija: I also ran the Pncconf tool and tried to configure the system with mostly defaults. I assigned the enc0 to Y axis encoder
03:36 AM imrija: but I can't seem to get any position reading in linuxcnc - am I missing something ?
03:37 AM gloops: jthornton Tom_L pcw_home
03:38 AM Wolf__: jt will probably be on in the next hour or 2
03:38 AM Wolf__: little early for the other two
03:38 AM * Wolf__ isnt sure why he is still up...
03:38 AM gloops: yeah the mesa people are around at various times, theyll be able help imrija, just a case of trying when theyre in here
03:39 AM imrija: Okay, I'll wait, thanks for information! I'm from Czech Republic, so sorry for my terrible english and weird timezone :P
03:40 AM Wolf__: english seems ok, I see worse from people in the USA
03:40 AM imrija: Thanks, I'll take that as an compliment
03:41 AM Wolf__: =)
04:47 AM jthornton: morning
04:47 AM XXCoder: yo
04:47 AM Tom_L: morning
04:51 AM Tom_L: imrija someone can probably help you here soon
04:51 AM * jthornton has never seen a 5i23
04:53 AM Tom_L: looks like pci with 40 pin headers
04:53 AM Tom_L: older card probably
04:53 AM XXCoder: pink_vampire: amazing witing pics.
04:53 AM XXCoder: as it person I love neat wiring
04:53 AM jthornton: looks like 50 pin headers like the rest of the mesa cards
04:54 AM Tom_L: well that's what i meant...
04:54 AM imrija: Good morning
04:55 AM imrija: The 5i23 is supposed to be pretty new PCI card with 3x 50 pin headers
04:55 AM jthornton: it must be flashable is has some svblabla.bit files
04:56 AM Tom_L: you will need to hook the scale up to pins that support it's function on the mesa card
04:56 AM jthornton: I wonder if it is just a 5i24 with vertical headers
04:56 AM Tom_L: probably something sneaky like that
04:57 AM imrija: Tom_L: I got an servo daughter card
04:57 AM imrija: 7i33
04:57 AM Tom_L: you need to get a pin list showing the pin functions
04:57 AM imrija: and the scale is connected to ENC0 header
04:57 AM Tom_L: dmesg i believe will get you that
04:57 AM jthornton: https://mesaus.com/info/mesa-pins.txt
04:58 AM jthornton: that's how to get a list of pins
04:58 AM Tom_L: or that
04:58 AM imrija: Thanks, didn't know that.
04:58 AM imrija: But do I need to flash the card or something? Or is this supposed to work out of the box ?
04:58 AM Tom_L: gotta go for a bit... sick animal here i'm dealing with
04:58 AM jthornton: ok take care
04:59 AM jthornton: imrija: do you know what firmware is flashed to the 5i23?
04:59 AM imrija: I have no idea, I've just selected something in Pncconfig tool, expecting it will be flashed to the card
05:00 AM imrija: But I guess it does not work like that
05:00 AM jthornton: I don't think pncconf can flash a card, the only one that can flash is my 7i96 config tool
05:00 AM imrija: So I need to pick a firmware and run mesaflash first ?
05:00 AM jthornton: you need mesaflash to read the card
05:01 AM jthornton: mesaflash --device 5i23 --readhmid
05:01 AM jthornton: that will read the current firmware
05:01 AM imrija: I'm unfortunately not near the machine now, so I can't run that. But I'll try it as soon as I'll get there.
05:01 AM jthornton: I'd hope who ever you purchased it from would have flashed it for you
05:02 AM imrija: It was sealed in antistatic bag directly from mesa systems
05:03 AM jthornton: they all are but at least I open them up and flash the correct firmware before shipping
05:03 AM jthornton: did you get it from eu surplus?
05:03 AM imrija: Nope, local reseller, but I think he did not do any of this.
05:04 AM jthornton: ok best to see what firmware is loaded on the card and maybe a little later pcw_home will be on here
05:05 AM imrija: Thanks, but I won't be able to get to the machine until like 16:00 UTC
05:06 AM jthornton: he is also on the forum so if there is a time difference the forum is the best place
05:06 AM jthornton: hmm the 5i23 looks like a shortened 5i20 to me
05:07 AM jthornton: but with a 400k gate fpga
05:07 AM jthornton: hmmm
05:08 AM imrija: I've also been told, that I don't need to flash this card manually (via commandline), by the reseller. But maybe he was wrong?
05:09 AM jthornton: he should know what he is selling, so if he told you that I'd guess you don't need to flash it
05:09 AM jthornton: you could always read the card and see what is on there
05:11 AM jthornton: lol I had to look up 16:00 UTC to see what the local time was and it's 11am
05:11 AM jthornton: hmm time for the chickens to wake up
05:12 AM imrija: I thought it would be easier to tell the time in UTC than Europe/Prague timezone :-D
05:13 AM jthornton: yep it's 5am so pretty early here still working on my first cup of coffee lol
05:14 AM * jthornton watches chicken tv
05:15 AM imrija: It's 11:00 here and I'm working on my second.
05:18 AM jthornton: just watching the chickens come out of the coop after the door opened and the lights came on... automagic chicken coop powered by Rasperry Pi 3
05:19 AM pink_vampire: i need to clean here
05:19 AM jthornton: when your done come down here and help me clean my shop lol
05:19 AM pink_vampire: why this is take sooo much time?
05:19 AM pink_vampire: i just finished my panel today
05:19 AM jthornton: photo?
05:19 AM XXCoder: my shop need to exist first. mind helping me make it exist so I can start cleaning inside of it?
05:20 AM pink_vampire: and i cleaned the lathe
05:20 AM pink_vampire: https://imgur.com/a/DHIUhbW
05:20 AM jthornton: XXCoder: you have room out back to build a shop?
05:20 AM XXCoder: yep but no money
05:21 AM Wolf__: I need a new box in my back yard for all my crap
05:21 AM jthornton: pink_vampire: looking good, I like the name
05:21 AM jthornton: my RPC control panel is named Linus
05:23 AM pink_vampire: thanks!
05:24 AM pink_vampire: XXCoder: I also saw now the compliments that you right - thanks!
05:24 AM Wolf__: I need to get off my ass and go check on getting a permit for new shop =/
05:26 AM rmu: pink_vampire: your gecko drive mounting bracket looks interesting. you didn't 3d print that did you?
05:27 AM pink_vampire: rmu: NO, with 60K rpm spindle it is much faster to just cut it from foam pvc and glue it
05:29 AM miss0r: g'day
05:31 AM jthornton: hey
05:31 AM XXCoder: yo
05:31 AM miss0r: Just got back from giving a client a WTF experience :)
05:31 AM miss0r: "YES the machine needs oil not to break!"
05:31 AM Wolf__: lol
05:32 AM miss0r: so... Three gears, 4 bushings and 6 bearings needs to be replaced
05:32 AM miss0r: luckily its a gear factory, so the gears they will have whipped up within next week. The rest is just easy turning at home here & the bearings are ordered.
05:33 AM miss0r: apparently the central oiling system had stopped working back in '98
05:33 AM jthornton: my mil first car all she did was drive it and put gas in until it died one day, no one bothered to tell her to have the oil changed
05:33 AM miss0r: so every time they started the machine (only runs 3 days a year) they poured some oil over the gears in the gearbox. it just never made it inside the bushings/bearings
05:33 AM miss0r: lol
05:34 AM XXCoder: LOL... i was playing a game... it went to future... of 2010.
05:34 AM XXCoder: city is in clouds.
05:34 AM Wolf__: central oiling ftw… https://i.imgur.com/LMfI6tN.jpg
05:34 AM miss0r: wtf am I looking at?
05:35 AM miss0r: somethings not right with that hose... :)
05:35 AM Wolf__: piece of wire stuck in one of the oil hoses
05:35 AM miss0r: I swear, it was like that when I got here
05:35 AM Wolf__: so the one shot just dumps all out of that one break
05:35 AM miss0r: yeah
05:35 AM Wolf__: thats the surface grinder I picked up
05:35 AM miss0r: the machine I was just out messing about with is a 1958 TOS gear mill
05:36 AM Wolf__: https://i.imgur.com/N0xB9JI.jpg =/
05:36 AM miss0r: for rather large gears (up to 2 meters in diameter, and a height of about 1 meter)
05:36 AM miss0r: that looks a smidge dry
05:37 AM Wolf__: https://i.imgur.com/Pop9vFT.jpg no oil didn’t help that thing =/
05:37 AM XXCoder: dont lok great
05:37 AM miss0r: damn
05:37 AM Wolf__: flaking is just about gone so not a good sign https://i.imgur.com/1r2OqUG.jpg
05:38 AM XXCoder: what is flaking?
05:38 AM miss0r: looks like a re-scrape to me
05:38 AM miss0r: XXCoder: The half moon pattern
05:38 AM XXCoder: oh poattern on rails
05:38 AM XXCoder: ya
05:38 AM miss0r: you apply that after a grinding job or a fine scraping job. its for oil retaining
05:38 AM Wolf__: ^
05:39 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Mill_holder1.jpg
05:39 AM Tom_L: one step closer to thread milling
05:39 AM miss0r: or, in some cases, like my mill for cosmetics :) it has the flaking pattern on non sliding surfaces :)
05:39 AM miss0r: tom_L: nice
05:40 AM miss0r: Tom_L: Some chattering going on in the bottom of one of those bores?
05:40 AM rmu: pink_vampire gone? i was asking because i hab multiple failures of power supplies where a heatsink managed to melt the hot snot off of some caps or inductors and then blocking the fan causing a slow painful death of power transistors and rectifiers
05:40 AM Tom_L: probably, it's an old old lathe
05:40 AM miss0r: middle one on the bottom
05:40 AM miss0r: yeah, I know that song
05:41 AM Tom_L: and i was in a hurry
05:41 AM Tom_L: the money part there is the threads
05:41 AM miss0r: you don't need to apologise :) hehe
05:41 AM miss0r: ./make up excuses :) We've all been there
05:42 AM miss0r: rmu: Nice, how'd you manage that?
05:47 AM Wolf__: miss0r: saying it looks like re-scrape or needs one lol
05:47 AM miss0r: like it needs one
05:47 AM miss0r: :)
05:47 AM miss0r: you could get realy lucky, that it is still within spec, so you can just re flake it. Wouldn't count' on it though
05:48 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Z_Axis_Pulley.jpg
05:48 AM Tom_L: miss0r the old clunker i'm dealing with
05:48 AM Wolf__: lol yeah, new shop 1st, then get my surface plates calibrated
05:48 AM miss0r: Tom_L: damn :) I would not enjoy that honnestly
05:49 AM Tom_L: got it used and had it most of my adult life
05:49 AM pink_vampire: Tom_L: nice lathe!
05:49 AM miss0r: Tom_L: Well, then you know it in and out I guess
05:50 AM Tom_L: we tolerate each other
05:50 AM miss0r: haha xD
05:51 AM Wolf__: miss0r: thinking, if=new shop, then host scraping class lol
05:52 AM miss0r: yeah. Just show the students how to do it on my mill :D
05:52 AM miss0r: or lathe
05:52 AM miss0r: :)
05:52 AM Wolf__: its that to travel to one of the kingway classes
05:53 AM Wolf__: s/to/or
06:02 AM Wolf__: https://www.bidspotter.com/en-us/auction-catalogues/www-maynards-com/catalogue-id-biditu10280/lot-84f157d6-a20f-45c9-8078-aa0800053b0f that might work
06:28 AM miss0r: man I love this new cut-off tool I've gotten
06:28 AM miss0r: I just had to mill 1.2mm off the bottom of the holder to make it fit within the ajustability of my tool change
06:28 AM miss0r: it is sweet :D
06:29 AM miss0r: I think I can cut steel to length faster on the lathe now, than on my cold saw
06:29 AM jthornton: dang that is a good one
06:30 AM miss0r: yeah
06:30 AM miss0r: I can run it fast and hard
06:30 AM miss0r: it just eats away
06:32 AM miss0r: I'll go mess a bit with my land rover engine - I've repaired a few machines at a shop that does engine block remachining. I made a good deal :D I'll be back later
08:20 AM rmu: miss0r: re. hot snot and heat sink, i didn't do anything special, it an error of the manufacturer to use hot glue in the first place
08:21 AM rmu: miss0r: i would not use a PLA 3d printed bracket to mount a heatsink, PLA seems to get pretty weak even at temperatures around 70°C
08:38 AM Loetmichel: hihi, just got a package from an military MRE manufacturer. 20 packs of sweet buiscuits "Panzerplatten", 10 cans od dark bread, 20 packs of instant vitamin C drink powder "exotic flavour" and 10 packs a 50g dark chocolate. 89 eur... maan is that stuff expensive... but now i have some long-lasting "emergency food" here at the company should i again notice at 3 in the evening that i forgot
08:38 AM Loetmichel: breakfast AND lunch again.
08:41 AM PL7icnc: rain outside in Germany
08:41 AM PL7icnc: somone on here that is also on the forum ?
08:42 AM jthornton: PL7icnc: yes, why?
08:42 AM PL7icnc: hi imade alot of info Posts they are under NOREPLAI in the list
08:43 AM PL7icnc: jthornton, can you just make a Replay whatever "Nice" Thanks ... so they are coming of the list
08:44 AM jthornton: I don't understand your request, do you have a link to your post?
08:44 AM PL7icnc: jthornton, all inside the list https://forum.linuxcnc.org/forum/noreplies
08:45 AM jthornton: if no one has replied then they will be in that list, I see plenty of views...
08:49 AM PL7icnc: all from myself
08:49 AM PL7icnc: its only info
08:49 AM PL7icnc: berside the ngcgui issue i like to be solfed
08:50 AM PL7icnc: jthornton, do you know if the ngcgui ttt is a NGC file that is caled or a C-Code internal that is used
08:57 AM JT-Shop: ttt is a program
08:58 AM JT-Shop: true type tracer or something like that
08:58 AM PL7icnc: i know
08:59 AM PL7icnc: but the NGCgui lods only the programm with the SCALE Font .... and where is this file that ads this Entry to the ngcgui
12:07 PM imrija_: Hello, I'm currently near the machine
12:07 PM imrija_: still seeking for help with MESA 5i23
12:07 PM imrija_: is anyone of the mesa people around yet ?
12:08 PM pink_vampire: help with what?
12:09 PM imrija_: I'm all new to the mesa cards and I can't get any readout from my linear scale.
12:09 PM imrija_: I don't know whether I'm doing something wrong
12:11 PM imrija_: I've been told that I need to check what firmware is my card running via mesaflash
12:11 PM imrija_: I did that, it does not run any hostmot firmware until I run linuxcnc
12:12 PM imrija_: and I tried to flash it too, but I got error message saying, that this card does not suport flashing
12:26 PM pcw_home: That's correct, 5I23s do not support flash
12:27 PM pcw_home: on cards tha do no support flash, the FPGA firmware is loaded when LinuxCNC starts (the firmware name is specified in the driver loadrt line)
12:29 PM pcw_home: If you wish to determine the pinout of the firmware, you can load it via mesaflash and then use mesaflash's readhmid option to print a pinout
12:29 PM pcw_home: eg:
12:30 PM pcw_home: sudo mesaflash --device 5i23 --program someoldbitfile.bit
12:30 PM pcw_home: sudo mesaflash --device 5i23 --readhmid > someoldbitfile.pin
12:31 PM imrija_: Thanks, that is what I also did
12:32 PM imrija_: I think I've found the culprit
12:32 PM imrija_: my scales are not TTL
12:33 PM pcw_home: differential is OK but analog needs an interpolator board
12:37 PM imrija_: yeah, they seem to be sine wave
12:50 PM imrija_: do you guys have any suggestion for cheap interpolator board ?
12:55 PM jthornton: pcw_home: the 5i23 looks like a shortened 5i20 with double size fpga chip?
12:56 PM jthornton: I seem to remember the 5i23 as a step up option for the chip or something now
12:59 PM pcw_home: Yes just newer (Spartan 3 vs Spartan2 but similar PCI bridge design)
01:01 PM pcw_home: bigger FPGA, DMA capable Bridge but both 5I20 and 5I23 are basically obsolete now
01:01 PM pcw_home: old parts that have doubled in cost...
01:09 PM JT-Shop: thanks
01:10 PM gloops: did imrija get his problem sorted? he was looking for help with mesa
01:16 PM fragalot: 'sup
01:20 PM imrija_: gloops: I have sine wave scales :/
01:21 PM gloops: sounds painful imrija_
01:22 PM imrija_: I need to get interface board that converts the sine waves to TTL, or get different linear scales
01:27 PM gloops: ahh ok - i dont know anything about mesa, but if you know what you need thats a start
01:45 PM pink_vampire: hi
01:50 PM JT-Shop: Gamo customer service is the best I've ever seen!
01:51 PM fragalot: jester.
01:53 PM methods_: pellet rifle gamo?
01:53 PM gloops: el Gamo
01:55 PM methods_: i have one of these
01:55 PM methods_: https://www.gamousa.com/product.aspx?product=Whisper%20Fusion%20Mach%201%20.177%20Cal&productID=583
01:55 PM methods_: nice little air rifle
01:55 PM JT-Shop: yea the .22 caliber whisper something
01:56 PM methods_: yeah fun little bugger
01:56 PM JT-Shop: whisper fusion mach 1
01:56 PM methods_: yeah that's what i hav
01:56 PM methods_: have even
01:57 PM JT-Shop: the .22 or .17?
01:57 PM JT-Shop: .177 even
01:57 PM methods_: .177
01:57 PM methods_: i should have gotten the .22
01:57 PM methods_: but the .177 is fine
01:57 PM JT-Shop: https://www.gamousa.com/product.aspx?productID=584
01:57 PM methods_: yeah
01:57 PM methods_: same as mine just .22
01:59 PM JT-Shop: I have that one and an older whisper .177 that they don't make anymore
02:00 PM JT-Shop: but the .177 will penetrate pretty good
02:01 PM JT-Shop: I was surprised how much effort the .22 takes to cock
02:01 PM methods_: yeah even the .177 takes a little bit of muscle
02:02 PM JT-Shop: I like the adjustable trigger on the fusion mach 1
02:02 PM * JT-Shop wanders down to th log yard to cut some rounds
02:03 PM methods_: i haven't even messsed with the trigger
02:19 PM Tom_L: jthornton
02:20 PM Tom_L: what did you do with the logger?
02:31 PM JT-Shop: a guy added support to turn on logging join, leave and quit
02:54 PM CaptHindsight: don't raise the bridge, lower the river https://www.reddit.com/r/ResinPrinterBuilders/
02:56 PM CaptHindsight: ever notice that some groups just ignore anything LCNC
02:56 PM CaptHindsight: solved your problem in minutes with LCNC
02:57 PM CaptHindsight: "but how do i do it (poorly) with a *duino?'
02:58 PM Jymmm: I suspect it's the latency requirements
02:59 PM CaptHindsight: latency between being exposed to information and it being useful in the brain?

03:16 PM CaptHindsight: gloops: funny, will anyone under 30 get the joke?
03:18 PM gloops: i dunno, there is a minor revival in carry on humour among far right college students in the UK
03:18 PM nos: CaptHindsight: The article links to a forum post by the guy who designed ODrive; a FOSS motor driver that presses brushless hobby motors into servo duty.
03:20 PM CaptHindsight: more crap I can't use in a real robot
03:21 PM CaptHindsight: https://static1.squarespace.com/static/58aff26de4fcb53b5efd2f02/t/593dee283e00be288f784f07/1497230900383/IMG_20170611_181036.jpg?format=750w
03:21 PM fragalot: because inferior robots are not real
03:21 PM CaptHindsight: featuring new silcone based universal one time use connectors
03:22 PM a-u: agreed - that stuff is mostly imaginary robotics
03:22 PM fragalot: CaptHindsight: they're self-welding.
03:23 PM fragalot: wait I just noticed which ones you meant. christ >.<
03:24 PM nos: Another FOSS option is VESC.
03:25 PM a-u: Likely a stupid question... but I have LCNC that seems to be running well, but on start-up I always get the: RTAPI: ERROR: Unexpected realtime delay on task 1 This Message will only display once per session. Run the Latency Test and resolve before continuing.
03:25 PM CaptHindsight: how about a not shitty open source hardware project?
03:25 PM nos: CaptHindsight: You do know that is what LinuxCNC IS right?
03:25 PM a-u: The question: how bad is this if everything works well?
03:26 PM gloops: well thats enough meshing for one session https://ibb.co/rsH8Q0f
03:26 PM CaptHindsight: nos: how is the head injury going?
03:26 PM fragalot: CaptHindsight: SEW? NotQuiteLCNC Heidenhain?
03:27 PM nos: CaptHindsight: Just admit your error. Spare me the ad-hominems.
03:28 PM gloops: a-u ignore that error message
03:29 PM CaptHindsight: nos: hardware?
03:29 PM CaptHindsight: kids out of school early this year?
03:30 PM a-u: mine is running on a dell 7010 - intel core 5 I think
03:31 PM nos: CaptHindsight: Cobbled together from whatever you find.
03:32 PM CaptHindsight: nos: don't hurt yourself
03:32 PM nos: Or do you tear out the brains from commercial CNC machines and replace it with LCNC?
03:32 PM nos: CaptHindsight: Are you drunk? Why can't you behave yourself?
03:33 PM CaptHindsight: nos: control issues?
03:35 PM nos: hm
03:36 PM nos: Well apparently you can put the oDrive or VESC software on your MCU of choice and pick your own FETs, and so perhaps drive proper industrial AC servos.
03:43 PM CaptHindsight: is there a website like hackaday only with good projects on it?
03:46 PM nos: hackaday.io has people's own projects.
03:46 PM Rab: CaptHindsight, how about an example?
03:47 PM Rab: Besides stmbl?
03:48 PM nos: Good projects often don't deliver on their open source promises. They get a Kickstarter campaign, then VC money, and then implode.
03:50 PM nos: Rab: this stmbl thing looks cool!
03:50 PM Rab: Also VESC is pretty rulin', and I'd be interested to hear why not.
03:52 PM nos: I'd like to see if one can run PMSMs using class-D amplifiers...
03:54 PM nos: You can get a 100W class-D amp for $7.58 on Aliexpress. Free shipping.
03:55 PM Rab: Worth every penny!
03:55 PM nos: :D
03:56 PM Tom_L: JT-Shop, i thought it already did that. i just have it turned off on mine
03:56 PM Tom_L: at least join/part
03:56 PM Rab: 100W doesn't go very far in machine tools applications.
03:57 PM Sabotend_ is now known as Sabotender
03:58 PM nos: yeah... And the price seems to go up very quickly.
03:59 PM JT-Shop: Tom_L: it was turned off but never tested turned on lol
04:01 PM Tom_L: when i first started using it, i had j/p on but dedided i didn't want it
04:01 PM Tom_L: so that part should have been tested
04:01 PM roycroft: class a amplifiers sound a lot better than class d
04:01 PM Tom_L: dunno about quit
04:01 PM roycroft: if you're going to be listening to your cnc machine all day, use a class a amp :)
04:02 PM nos: roycroft: You are right, but at 2kW they would melt through the floor.
04:02 PM Tom_L: https://www.ebay.com/itm/HFS-Magnetic-Base-Adjustable-Metal-Test-Indicator-Holder-Digital-Level-Stand-14/272726131754?epid=1228736817&hash=item3f7fbe842a:g:HJsAAOSwIspaeMCL
04:02 PM roycroft: but your ears would not be complaining
04:02 PM Tom_L: for the price, that's not a bad base
04:02 PM nos: PWM / Class-D is used because MOSFETs are good at full on / full off.
04:03 PM roycroft: my main hifi gear is vintage mcintosh - i'm rather particular about what reaches my ears :)
04:04 PM roycroft: none of that sansuzi crap for me
04:05 PM nos: Tom_L: Those have a rod which is actuated by the hand wheel, and the force is taken up in this dinky little ring in a groove in aluminium.
04:06 PM nos: Tighten it too much and it pops right out, stripping the aluminium.
04:06 PM Tom_L: good to know
04:06 PM Tom_L: noga is better quality i'm sure
04:06 PM nos: I think those are hydraulic!
04:06 PM Tom_L: noga?
04:06 PM nos: ya
04:06 PM Tom_L: huh
04:07 PM nos: These cheap ones work fine as long as you don't over-tighten.
04:07 PM Rab: Related to class D audio motor control: https://www.youtube.com/watch?v=-SDYdHzT7Qw
04:07 PM Rab: Beats the Imperial March played on a 3D printer, IMO.
04:08 PM nos: :D
04:08 PM roycroft: i love my noga indicator holder
04:08 PM roycroft: anything else is definitely not scottish!
04:09 PM a-u: cheap from the harbor: https://www.harborfreight.com/multi-position-magnetic-base-with-fine-adjustment-63663.html
04:10 PM Rab: I think they mean "fine" as in "OK, fine".
04:10 PM roycroft: the next one i get i'll order with a micro adjust on both the base end and the indicator end
04:11 PM nos: ... wait
04:12 PM roycroft: https://www.ebay.com/itm/163591934298
04:12 PM roycroft: there's one you might be able to get fairly cheap
04:12 PM nos: https://www.aliexpress.com/item/Ghxamp-1000W-Amplifier-Board-HIFI-IRS2092-IRFB4227-Mono-Class-D-Power-AMP-Amplifier-board-High-Power/32892208758.html
04:12 PM nos: 3 of those would be 3kW.
04:13 PM CaptHindsight: Rab: how about Vulkan for LCNC? REing U/EFI blobs for x86 in the past 10 years, RE Broadcom ethernet controller blobs and similar
04:13 PM CaptHindsight: useful projects
04:14 PM CaptHindsight: help this guy out http://linux-sunxi.org/Mali#Utgard_.28Mali-400_and_Mali-450.29
04:14 PM nos: https://news.ycombinator.com/
04:14 PM nos: They have a lot of boring busines stuff too though.
04:15 PM CaptHindsight: R.E. RF modem blobs for LTE
04:16 PM Rab: PC stuff is dull as a box of rocks, doesn't count as "hardware".
04:16 PM srk: this
04:18 PM nos: These are indeed very useful, noble projects. However, most self-described 'hackers' on youtube are bros with 3D printers and far from noble.
04:18 PM * srk just quit another IT job to able to work on machine control and robotics
04:18 PM nos: HaD is at least nowhere near as bad.
04:19 PM nos: srk: I too quit IT after 10 years to become a machinist.
04:19 PM srk: :))
04:19 PM nos: Weeks go by quick and my neck and shoulders don't hurt constantly.
04:19 PM CaptHindsight: https://www.thingiverse.com/thing:199786
04:20 PM nos: Outstanding.
04:20 PM Rab: CaptHindsight, also, where's that open sores 5-axis CAM I feel we were promised?
04:20 PM srk: I've started to work on canopen bldc control for CNCs last year (https://distrap.org/) but the dayjob took all the time and willpower to work on that
04:20 PM srk: Rab: BlenderCAM maybe
04:21 PM CaptHindsight: Rab: Who promised YOU that?
04:21 PM Rab: CaptHindsight, I feel entitled to it, isn't that the same thing?
04:21 PM CaptHindsight: blendercam was funded a few years ago, but no longer
04:22 PM nos: lol
04:22 PM srk: ah, still listed as not yet supported :)
04:23 PM nos: srk: This looks very cool... You don't mind if I use this for the army of humanoid robots I'm going to take over the world with?
04:23 PM a-u: I'd like to share in entitlement to CAM above 3 axis at a reasonable price.
04:23 PM srk: np, humanity sucks anyway
04:23 PM nos: Agreed.
04:24 PM roycroft: this blendercam? https://www.youtube.com/watch?v=KWqw5SpITg8
04:25 PM nos: I think Fusion 360 is multi-axis...
04:26 PM CaptHindsight: open source cooperation from a bunch of misfits
04:26 PM nos: But it won't even start in Wine.
04:28 PM nos: srk: I think ROS has support for CAN, too.
04:28 PM srk: it does
04:28 PM CaptHindsight: runs fine on a Win 10 copy from China for $10
04:28 PM CaptHindsight: so ZI've heard
04:28 PM srk: there's CANOpen master (ros-industrial)
04:28 PM CaptHindsight: -Z
04:29 PM srk: there's also motion planning for CNCs which makes my job kind-of easier
04:29 PM srk: (still want to try implementing whole stack)
04:31 PM CaptHindsight: 10 devs cooperating on a 5-axis CAM for something like FreeCAD would take a few months
04:31 PM CaptHindsight: decide on the GUI and framework up front
04:31 PM CaptHindsight: the core math is not where the work is
04:31 PM nos: I need my robots to still function after they have been used for target-practice. I assume distributing control using CAN would aid in that?
04:32 PM srk: for sure :)
04:32 PM CaptHindsight: it's mostly setting up how to deal with a wide range of cutting tools
04:32 PM nos: yiss!
04:32 PM srk: the first robotic project I've worked on failed spectacularly due to encoders connected via I2C
04:33 PM srk: bit of noise from teh motors and robot was spinning madly
04:33 PM CaptHindsight: more likely you'd have 10 devs competing to write the whole thing themselves vs working together
04:33 PM nos: hm!
04:34 PM CaptHindsight: srk: did you ask a grown up about your plans?
04:34 PM CaptHindsight: discuss the design beforehand?
04:34 PM srk: CaptHindsight: which part? hardware?
04:35 PM srk: or a whole project?
04:35 PM CaptHindsight: "the first robotic project"
04:35 PM CaptHindsight: portions or whole
04:35 PM srk: heh, yeah there was an older person coordinating us
04:36 PM gregcnc: capt did you enjoy the taste of spring?
04:36 PM srk: well, you still find people who think i2c for robotics is a good idea
04:37 PM roycroft: it's going to be 23 here on monday!
04:37 PM roycroft: that's almost a taste of summer
04:38 PM srk: heh
04:38 PM roycroft: first birkenstock day of the year
04:38 PM roycroft: it's 16 right now
04:38 PM srk: I couldn't wait for nice weather and burned my RC reciever on a quad due to rain
04:38 PM srk: today
04:38 PM roycroft: hopefully the rest of the snow will melt over the weekend
04:39 PM roycroft: i can't remember snow being on the ground for two weeks ever since i lived in chicago, and i moved away from there in 1980
04:39 PM Rab: CaptHindsight, competing efforts are an inevitable consequence of necessary and vital UI toolkit bikeshedding.
04:39 PM Rab: Imagine how much awesome software we'd have if everybody was stuck using Motif.
04:40 PM roycroft: i always liked motif
04:41 PM roycroft: and lesstif was a worthy open source clone, so the folks who hate on motif because it's proprietary were just baseless haters
04:41 PM CaptHindsight: gregcnc: was stuck inside until 3 yesterday, caught the last hour or two only
04:42 PM gregcnc: I only went out to check the mail box and pick up coffee beans. It was nice.
04:42 PM gregcnc: The rail upgrade on that photon did wonders
04:42 PM CaptHindsight: heading out now
04:42 PM gregcnc: I was thinking about getting one, but reviews are mixed on amazon
04:48 PM nos: Wow ROS-industrial is pretty big.
05:03 PM Deejay: gn8
05:52 PM weenerdog: howdy
05:59 PM a-u: hiya too
06:14 PM a-u: seems jesseg wants to be a spam bot?
06:36 PM jthornton: having some connectivity issues I guess
06:42 PM XXCoder: lol thats why i love norepeat. i only see 2 d/cs
06:43 PM a-u: the Flood message seemed like a DOS breaker kicking in - but I don't know this tech well
06:43 PM a-u: good point - I should look for a real client
06:44 PM XXCoder: i wrote the norepeat for hexchat
06:44 PM jthornton: I have it turned off an only see it on riot
06:44 PM XXCoder: i wanted to see disconnects but not repeative disconnects without talking
06:44 PM XXCoder: well thats what it does.
06:45 PM jthornton: cool
06:45 PM XXCoder: https://github.com/rredford/Hexchat.NoRepeat
06:45 PM * jthornton ponders how to make a conversational thing for qtpyvcp
06:46 PM jthornton: cool
06:46 PM a-u: same - but for MPG buttons
06:46 PM XXCoder: my spttoomany is set at 3, toomany at 2
06:48 PM jthornton: dinner time here
06:49 PM a-u: past time here - and pizza night
06:49 PM XXCoder: lunch
06:51 PM a-u: I caught the opinion that a RTAI message on launch is kinda normal, as long as everything else works well. Did I get that right?
07:00 PM pcw_mesa: I honestly think RTAI latency messages are kinda broken
07:00 PM pcw_mesa: They only display one error so if its some kind of one time only error due to caching or something you cannot tell
07:01 PM pcw_mesa: better would be to count all errors and the magnitude of the worst
07:02 PM a-u: Thanks - and that was what I had gathered. Something about the initial launch. When LCNC stops it has an "exceeded" delay message that has always been zero for me...
07:02 PM a-u: ... but I'm working on upgrade and improve and that one won't go away unless I set the base way way up... too far to be usable.
07:25 PM CaptHindsight: RTAI works best when configured for the cpu, one size fits all just sort of works
07:44 PM pink_vampire: HI
07:44 PM XXCoder: hey pink
07:45 PM pink_vampire: hi XXCoder, how are you
07:45 PM XXCoder: tired lol
07:45 PM XXCoder: had to get my brother to airport at 5 am, and i normally sleep at 4
07:45 PM XXCoder: got home at 6 am, finally asleep 40 min later
07:46 PM XXCoder: then had to wake up and drive to pick up my nephew from bus from school
07:46 PM pink_vampire: long day..
07:46 PM XXCoder: yeah
07:46 PM XXCoder: that was after working 10 hours too so was very tired already
07:47 PM pink_vampire: I need to clean here and organize the huge mess i did, and it feel like it never going to end
07:48 PM XXCoder: shop cleaning never ends
07:48 PM pink_vampire: i clean the lathe
07:48 PM pink_vampire: and i need to clean the table here
07:50 PM pink_vampire: also i need to add power outlet in the panel, for the coolant pump
07:54 PM XXCoder: nice
07:56 PM pink_vampire: I'm drilling the electrical box
08:19 PM jesseg: Sorry guys, my internet's been killing me.
08:19 PM jesseg: seems stable now.
08:20 PM XXCoder: yay
08:25 PM weenerdog: howdy again
08:30 PM infornography: ello
08:30 PM weenerdog: sup
08:31 PM XXCoder: heys
08:33 PM infornography: in my country, dog is emergency food supply

08:51 PM andypugh: The only metric allen key in the USA?
08:51 PM CaptHindsight: nah they sell them near everywhere
08:51 PM andypugh: But USA-ians are not allowed to buy them, I thought ;-)
08:52 PM CaptHindsight: heh, metric fasteners are more hit or miss
08:52 PM XXCoder: we pay $100 fee each time we buy something metric
08:52 PM XXCoder: per item
08:52 PM CaptHindsight: the cars were imperial and metric for decades
08:52 PM CaptHindsight: now mostly metric
08:53 PM XXCoder: yeah
08:53 PM CaptHindsight: I still have all my imperial special tools for autos
08:53 PM CaptHindsight: sensor and spark plug sockets sockets
08:54 PM pink_vampire: I love my 10-32
08:54 PM pink_vampire: skunkworks: amazing stuff!
08:54 PM CaptHindsight: carburetor and distributor wrenches
08:55 PM CaptHindsight: andypugh: I have a full set of left hand metric screw drivers
09:01 PM andypugh: I think everyone has a full set of zero of those.
09:04 PM CaptHindsight: I stock up those 999 pice screw driver sets since they have every security fastener matched
09:05 PM andypugh: Anyway, bed time

11:01 PM pink_vampire: Tom_L: VERY NICE!!!!!!!!!!
11:01 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Mill_holder3.jpg
11:01 PM Tom_L: it fits too :)
11:02 PM pink_vampire: how the tool look like?
11:02 PM Tom_L: the cutter?
11:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill2.jpg
11:03 PM Tom_L: the big one is 3/4 16
11:03 PM pink_vampire: where did you got them?
11:04 PM pink_vampire: or did you made them?
11:04 PM Tom_L: http://onlinecarbide.com/
11:05 PM Tom_L: i had to cut the shank so it would fit
11:05 PM Tom_L: used my threadmill macro i just wrote to cut them
11:06 PM pink_vampire: $25 for each
11:06 PM pink_vampire: wow
11:06 PM Tom_L: http://onlinecarbide.com/341032tpi.html
11:06 PM Tom_L: no
11:07 PM Tom_L: it's like buying a whole set of tap and dies
11:07 PM Tom_L: metric and imperial
11:07 PM pink_vampire: WTF $89.95
11:07 PM pink_vampire: wow for a hobby
11:07 PM pink_vampire: crazy
11:08 PM Tom_L: i take my toys seriously
11:09 PM pink_vampire: i just added a power outlets to my panel to drive the coolant pump, an who know what more will go there
11:09 PM Wolf__: lol, thats not a 10-32 tap pink
11:10 PM Wolf__: thats pretty cheap vs how much a >0.75” tap costs
11:10 PM Tom_L: i was rather happy the macro worked excellent.
11:10 PM Tom_L: i had to adjust it by .002" for clearance
11:10 PM Tom_L: i'll probably build that into the macro so you just enter the major and minor diameters
11:11 PM pink_vampire: ridgid tapping is much faster and cheaper (yeah no over size)
11:11 PM Wolf__: not cheaper…
11:11 PM Tom_L: true but my spindle won't turn a 3/4 16 tap
11:11 PM Lcvette: Tom_L: faster faster
11:11 PM Tom_L: pfft
11:11 PM Tom_L: the spindle doesn't like it any faster
11:12 PM Lcvette: Single point?
11:12 PM Tom_L: yeah
11:12 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill2.jpg
11:12 PM Tom_L: 6 'flute'
11:13 PM trentster: Hey all, can anyone give me a pointer on what the Wiper related to on my BOB analogue input. I am trying to connect to my VFD and I am not sure of the wiring. https://take.ms/zggW6
11:13 PM Lcvette: But single point
11:13 PM Tom_L: yup
11:15 PM pink_vampire: probing > https://i.imgur.com/wUisVZ2.png > https://i.imgur.com/dgOCStt.png > installed https://i.imgur.com/rvrdhlu.png
11:15 PM Lcvette: https://youtu.be/tIf6IUTWeZM
11:16 PM Lcvette: Go to 1:15
11:17 PM pink_vampire: 1/4-20 is the most generic tap
11:18 PM XXCoder: nice
11:18 PM Lcvette: In iron
11:18 PM Lcvette: You should be able to speed it up a good bit Tom
11:19 PM trentster: On that screenshot above it says that the BOB expects 10V in from the VFD, but my VFD only has a 12V out port. DOes this mean I need to use a resistor to drop the voltage from 12v to 10v from the VFD?
11:20 PM Lcvette: I run multi flute single revolution ThreadMills way faster than you were running that single point and that single point you have is a very beefy single point with allot more rigidity
11:21 PM Lcvette: You can make multiple passes
11:21 PM Lcvette: Or a full depth and a spring
11:22 PM _unreal_: midnight no wonder I cant focus
11:23 PM Tom_L: Lcvette i see you did 3 passes too
11:23 PM Lcvette: 2 and a spring
11:24 PM Lcvette: In aluminum I only do 1 and a spring
11:24 PM pink_vampire: Lcvette: the machine on the video it is your machine?
11:24 PM Lcvette: My little mill
11:25 PM Lcvette: G0704
11:25 PM pink_vampire: we have the same mill
11:25 PM pink_vampire: your look faster
11:25 PM Lcvette: Hurray!
11:25 PM Lcvette: Grease lightning!
11:25 PM Lcvette: Lol
11:25 PM Lcvette: Slow
11:26 PM Lcvette: Looks fast. Because of small moves
11:26 PM pink_vampire: what is your rapid?
11:27 PM Lcvette: There? Probably 150-200ish
11:27 PM pink_vampire: mm/min?
11:27 PM Lcvette: Ipm
11:28 PM Tom_L: oh i tried 2.8 on it tonight and it wouldn't run
11:28 PM Lcvette: I can turn x and y up to 250ipm, but z is best about 200 max
11:28 PM pink_vampire: i mean in general what is the fastest rapid move you can do?
11:28 PM pink_vampire: yeah this is much faster then my machine
11:29 PM pink_vampire: are you using mesa card?
11:29 PM Tom_L: i have no reason to push mine
11:29 PM Lcvette: No, that machine is still running mach3 with an Ethernet smoothstepper
11:30 PM pink_vampire: mine is 2400mm/min the house can't take more then that
11:30 PM Lcvette: That's not bad
11:31 PM Lcvette: Tom_L: that's cool
11:31 PM pink_vampire: the motors can push it up to 15000mm/min, but the house move
11:31 PM Lcvette: Lol
11:32 PM pink_vampire: apartment with wooden floor
11:34 PM _unreal_: always a good timne
11:34 PM pink_vampire: _unreal_: for?
11:34 PM _unreal_: flexy floor
11:34 PM XXCoder: so flexy floor is good for flexy floor?
11:34 PM pink_vampire: lol no
11:35 PM _unreal_: XXCoder, I think I confused you
11:35 PM XXCoder: lol
11:35 PM Lcvette: Tom_L: just thought I'd share in case you weren't sure how fast to go with thread milling. When I started I had no clue and there wasn't allot of information out there in it
11:37 PM pink_vampire: Lcvette: do you have backlash on your machine?
11:38 PM Lcvette: Yeah, .001-.0015" depending on the axis. I'm still on single ballnuts
11:39 PM pink_vampire: my Y axis start to get some backlash
11:39 PM pink_vampire: and i have no idea how to compensate for it
11:40 PM Lcvette: Double or single nuts?
11:40 PM pink_vampire: single nuts
11:40 PM Lcvette: Best option is upgrade to double nuts
11:41 PM pink_vampire: where do you get now some thing like that for 1605?
11:41 PM Lcvette: That will get you around 0.0005"
11:41 PM Lcvette: Anywhere now days
11:42 PM Lcvette: Best to have new screws made too
11:42 PM Lcvette: So the for is right
11:42 PM pink_vampire: the problem is that the Y axis is not supported on the back side
11:43 PM Lcvette: That's ok
11:43 PM Lcvette: What bearings for the fixed side?
11:44 PM pink_vampire: small holes become rectangular a bit
11:44 PM pink_vampire: the stock bearings
11:44 PM Lcvette: The thrust bearings?
11:44 PM pink_vampire: yeah
11:45 PM Lcvette: That's most likely your problem
11:45 PM pink_vampire: and i know the Y axis not running concentric
11:45 PM Lcvette: They have no radial support
11:45 PM pink_vampire: where do i get new bearings?
11:46 PM Lcvette: If I were in your shoes I would use tapered roller bearings
11:47 PM Lcvette: Timkin 2047/2126
11:47 PM Wolf__: why not angular contact ?
11:48 PM pink_vampire: those are thrust bearings?
11:48 PM Lcvette: Because the correct ac bearing for a fixed support is a 60deg AC bearing with high contact area and cost about $390/bearing
11:49 PM pink_vampire: wow is is crazy
11:49 PM pink_vampire: what did you put on your machine?
11:50 PM Lcvette: It has very close to the dynamic load reading of a tapered roller bearing and 3 times the reading of a cheap ac bearing
11:50 PM Lcvette: They use smaller balls and higher ball count
11:51 PM pink_vampire: the Timken 2047/2126?
11:51 PM Lcvette: I have gone through three sets of cheap 40degree cheap ac bearings on mine
11:52 PM pink_vampire: it is look like a roller type bearing
11:52 PM Lcvette: They eventually fail
11:52 PM Lcvette: Crumbled ball
11:52 PM Lcvette: It is
11:52 PM Lcvette: Tapered roller
11:52 PM pink_vampire: yes correct
11:52 PM Lcvette: Has very good axial and radial load rating
11:53 PM pink_vampire: and how many i need?
11:53 PM Wolf__: only problem I have is the X2 I’m doing has little space so I’m stuck with 1204 ballscrew
11:53 PM pink_vampire: Wolf__: ???
11:53 PM Wolf__: kinda doubt that I could stuff a 16mm screw in it
11:53 PM Lcvette: And in such a small bearing size offers much better super than the tiny ac bearings
11:54 PM pink_vampire: Lcvette: do you put only one?
11:54 PM Lcvette: Support
11:54 PM Lcvette: 2
11:55 PM Wolf__: https://i.imgur.com/5SkXbBt.jpg tight…
11:56 PM Lcvette: X2 is much smaller
11:56 PM pink_vampire: Wolf__: i had to cut my 1605 ball nut
11:56 PM Lcvette: Not as much weight to move
11:57 PM Wolf__: I had to pocket the saddle to make stuff fit https://i.imgur.com/Bfyg7gw.jpg
11:58 PM pink_vampire: Lcvette: https://i.imgur.com/LzVOmM7.png

11:58 PM Lcvette: You will need to make a bearing mount
