#linuxcnc Logs

Aug 26 2023

01:12 AM Deejay: moin
03:20 AM travis_farmer: Morning :-)
06:43 AM rigid: is there a chance the current raspberry image is corrupted at http://www.linuxcnc.org/iso/linuxcnc-2.8.1-pi4.zip ?
06:44 AM rigid: for me it doesn't boot on pi4, pi3 and pi zero
06:44 AM rigid: could be some quirk but I tried multiple sd cards, sd adapters etc.
06:46 AM rigid: oh, there's newer versions... yay! it's just the link in the docs is outdated
06:54 AM rigid: hm, nah... those newers are not suited for the pi :(
07:05 AM travis_farmer: https://gnipsel.com/linuxcnc/ check the Rpi4 tutorials. not sure if they work, but they are newer
09:06 AM Tom_L: rigid, possibly
09:07 AM Tom_L: it would be for RPI4 8gb
09:07 AM Tom_L: there might be a 2.8.4 one but that may only be for pc
09:09 AM Tom_L: rigid, also try here: http://buildbot.linuxcnc.org/dists/buster/2.9-rtpreempt/binary-armhf/
09:09 AM Tom_L: is if armhf or arm64?
09:09 AM Tom_L: s/if/it
09:14 AM rigid: Tom_L: oh, i think I only have 4GB versions here
09:15 AM rigid: but it still should boot I guess
09:18 AM rigid: Tom_L: arm64
09:19 AM Tom_L: none of those are for arm64
09:19 AM rigid: yeah, saw it. only amd64 :-(
09:20 AM rigid: and i386 :-D
09:20 AM Tom_L: find an arrmhf one with the os
09:20 AM rigid: well, just stale Contents files
09:20 AM Tom_L: gtg. later...
10:20 AM Unterhaus__: the current Pi image doesn't work on any pi purchased over the last couple of years
10:21 AM Unterhaus__: I have proposed that it be removed
10:21 AM Unterhaus__ is now known as Unterhausen
10:22 AM Unterhausen: I have no idea what the issue is, but I took an sd card with that image on it from an older working pi and put it in a new one and it didn't boot
10:23 AM Unterhausen: this issue comes up on occasion
10:41 AM Tom_L: yeah i recall that.. there's a different chip (forget which one) on the newer ones
10:48 AM Tom_L: guess you can build from source
11:40 AM Unterhausen: Installing on a pi isn't hard, just follow JT's instructions. But the image causes frustration
11:42 AM CaptHindsight: Starts from $64 https://www.zimaboard.com/blade/
11:42 AM CaptHindsight: seems to be trying to compete with the Rpi's
11:43 AM CaptHindsight: might be 12V power
11:43 AM CaptHindsight: yes, 12V/3A USB Type-C Power
11:44 AM CaptHindsight: so it's a quad core Intel Celeron board
11:45 AM CaptHindsight: SODIMM Slot, compatible with 16GB DDR3L
11:47 AM Unterhausen: is the zimaboard website intentionally slowed down?
11:47 AM CaptHindsight: 2x the footprint of an Rpi though
11:48 AM CaptHindsight: maybe my post was too popular?
11:48 AM Unterhausen: I'm a little frustrated that picture doesn't scroll more
11:49 AM Unterhausen: I would prefer nvme instead of sata
11:50 AM CaptHindsight: it has PCIe so just plug it in
11:51 AM CaptHindsight: you get what comes on the chipset
11:52 AM CaptHindsight: wish it was AMD but not bad for an x86/am64 board
11:52 AM Unterhausen: that pcie port is never going to be used
11:53 AM CaptHindsight: https://linuxgizmos.com/files/ZimaBlade-peripherals.jpg
11:53 AM CaptHindsight: short PCIe cable and stack Mesa right on top
11:53 AM Unterhausen: there is a modern chipset that doesn't support nvme?
11:54 AM Unterhausen: also be nice to have a wifi slot
11:54 AM CaptHindsight: https://linuxgizmos.com/files/ZimaBlade-top-bottom.jpg
11:54 AM Unterhausen: I guess that's the $160 version
11:55 AM Unterhausen: does it come with a case?
11:55 AM CaptHindsight: https://www.crowdsupply.com/icewhale-technology/zimablade
11:59 AM Unterhausen: price is too low, I won't be able to buy one before they go out of business
12:00 PM Unterhausen: tempting though
12:02 PM CaptHindsight: hah https://cdn.discordapp.com/attachments/294098819702980608/1145040020084903956/370441846_590021596677163_5683112719475769154_n.png
12:02 PM CaptHindsight: Integrated 32 GB eMMC
12:03 PM Unterhausen: I missed that, give me a second ethernet port and I'll take 5
12:05 PM Unterhausen: I'm still prejudiced against pi for large machines. Might be unreasonable
12:10 PM CaptHindsight: the RK3588 boards come with up to 32GB ram
12:13 PM CaptHindsight: https://www.aliexpress.us/item/3256805762399190.html dual 2.5GB Ethernet
12:16 PM Unterhausen: I trust an orange pi even less
12:16 PM Unterhausen: I like the fact that the zima board is intel
12:17 PM Unterhausen: is there a way to get a list of firmware for a 5i25? Is there one that feeds a standard parport bob and smart serial
12:20 PM Unterhausen: I guess I could d/l the support files
12:21 PM Unterhausen: okay, d/l the support files
12:26 PM Unterhausen: okay, no 5125 bob + 7i74 firmware
12:38 PM Unterhausen: lots of b.s. whining on the FB lcnc group by a couple of people that aren't willing to help themselves to any degree
12:43 PM Unterhausen: whole new crew that just bashes lcnc
12:44 PM travis_farmer: those that bash LCNC, are those that can't comprehend LCNC ;-)
12:49 PM Unterhausen: one of the bashers wants it to work like grbl. I told him to use grbl
12:49 PM travis_farmer: yeah, if they want inferior, then do't use LCNC :-)
01:07 PM Unterhausen: is mesact ready for a newbie?
01:08 PM Tom_L: yes
01:09 PM Tom_L: for alot of the newer cards
01:11 PM Unterhausen: how about a 5i25?
01:12 PM Unterhausen: I told the guy to post on the forum, FB is full of very confident and very wrong people
01:13 PM Tom_L: i don't have linux booted right now to see
01:13 PM Unterhausen: mesact2 is now mesact, correct?
01:13 PM Tom_L: yes
01:14 PM Tom_L: https://www.gnipsel.com/linuxcnc/mesact/index.html
01:14 PM Tom_L: may not be up to date yet
01:14 PM Tom_L: https://github.com/jethornton/mesact
01:17 PM Unterhausen: I begged him to ask his question on the forum
01:18 PM Unterhausen: literally
01:19 PM Unterhausen: this whole experience is reminding me that the internet was a mistake
01:20 PM Unterhausen: I hope someday to tell that to Al Gore
01:24 PM Unterhausen: he's been asking questions on fb for weeks now and he gets so many contradictory answers no wonder he's confused
01:25 PM Unterhausen: Maybe we should talk sven into deleting the fb group
01:31 PM Tom_L: i know jt has been trying to get the newest cards supported first
01:31 PM Tom_L: and the rest are going to probably be reconfigured with the new chips or discontinued
01:32 PM Tom_L: i wasn't familiar with the fb group
01:32 PM Tom_L: maybe i heard of it once
01:33 PM Tom_L: contradictory answers / fb kinda go hand in hand
01:33 PM Unterhausen: I complain about it periodically on here
01:33 PM Tom_L: so what board were you asking about now?
01:33 PM Tom_L: just booted
01:33 PM Unterhausen: so probably, if it weren't for me you would be blissfully unaware of its existence
01:33 PM Unterhausen: 5i25
01:34 PM Tom_L: yes
01:34 PM Unterhausen: okay, thanks. I'm not telling him that much because i hope he will post on the forum
01:34 PM Tom_L: he doesn't have it greyed out so he's either got it ready or plans to soon
01:35 PM Tom_L: it's not ready yet
01:35 PM Tom_L: but he's probably planning to do that one
01:35 PM Unterhausen: pncconf works for a stepper board, doesn't it?
01:35 PM Tom_L: idk, i've never used it
01:35 PM Tom_L: should
01:36 PM Tom_L: post him the wiki step timing page
01:36 PM Unterhausen: he's nowhere near that stage because he keeps asking his questions on fb
01:36 PM Tom_L: lists quite a few drivers
01:36 PM Tom_L: doesn't sound like he wants to give that up either
01:36 PM Tom_L: i can't help him
01:37 PM Unterhausen: I feel like he's going to be another "lcnc is too complicated" whiner
01:37 PM Tom_L: just tell him to use mach
01:37 PM Tom_L: then come back when he's actually ready
01:37 PM Unterhausen: I told one of the whiners that if they didn't want help getting lcnc running, they should join a grbl group and not get help there
01:38 PM Tom_L: at least here, none of us have all the answers but the answers given are generally more accurate
01:38 PM travis_farmer: dang, starting to get bad painful arthritis in my right hand... hurts to type and use a mouse :-(
01:38 PM Tom_L: except travis_farmer
01:38 PM travis_farmer: :-(
01:39 PM Tom_L: just had to get your attention :)
01:39 PM Unterhausen: don't be mean, his hand hurts too much to type a witty response
01:39 PM Unterhausen: if you say something wrong here, there is immediate feedback. Usually
01:40 PM Unterhausen: but don't listen to me, I usually provide misinformation
01:40 PM travis_farmer: finally got my gitlab server running happily :-)
01:40 PM Tom_L: i do that sometimes just to get feedback and be corrected
01:40 PM Tom_L: rather than just silence
01:41 PM Unterhausen: right, Cunningham's rule
01:41 PM Unterhausen: the way to get the right answer on the internet is to post the wrong answer and wait for the corrections
01:41 PM Tom_L: better than silence
01:42 PM travis_farmer: i have an unofficial mirror of LinuxCNC on it (big download..) but keeping it up to date depends on if i can get an opensource license for gitlab
01:42 PM Unterhausen: Cunningham said not to bother asking the question, just post the wrong thing
01:43 PM Tom_L: apples are blue
01:43 PM Unterhausen: I just saw some blue apples, nice try
01:43 PM Tom_L: anyway, for the 5i25, jt has it listed but no firmware to select yet
01:43 PM travis_farmer: man, JT goes away, and Tom_L goes loony with boredom ;-)
01:44 PM Unterhausen: can't it use fw that the person d/l themselves?
01:44 PM Tom_L: but i think most of the major bugs are taken care of, it's just a matter of adding more boards now i think
01:45 PM Tom_L: not yet
01:45 PM Tom_L: i think he has a little more to do on the spindle section
01:48 PM Tom_L: i think the next card he is likely to do is the 7i92T
01:49 PM Tom_L: Unterhausen, does this guy already have cards?
01:49 PM Unterhausen: yeah, purchased at an estate sale
01:49 PM Unterhausen: for $5
01:49 PM Tom_L: ok
01:50 PM Tom_L: those are the 50 pin headers?
01:51 PM Tom_L: yeah
01:51 PM Tom_L: and a db25 out the back
01:54 PM CaptHindsight: Unterhausen: consider the source, it's facebook
01:54 PM CaptHindsight: I ignore the LCNC forum on 4chan as well
01:55 PM Unterhausen: no, I think there is a 26pin header and a db 25 on the back
01:56 PM Unterhausen: Unless it's something trivial, I tell them to go to the forum. Same with reddit
01:56 PM Tom_L: yeah that's right. the header looked wider before i zoomed on it
01:57 PM Tom_L: if it's not mentioned on the lcnc site it doesn't exhist imo :)
01:58 PM Unterhausen: one of the naysayers asked why the fb group exists if not to offer help. The only value in it is to steer people to the forum, I think
01:58 PM Tom_L: CaptHindsight, is the matrix/discord bridge broke for good?
01:59 PM CaptHindsight: good for now :)
01:59 PM Tom_L: heh
02:03 PM Unterhausen: good, as in still broken
02:05 PM travis_farmer: hmmm, i have my LCNC code mirror working on my gitlab, but it will not mirror the binaries (.deb), just the code and branches. ahh well, may be useful to somebody one of these days (man it hurts to type...)
02:07 PM Tom_L: is gitlab a 'home' version of github server?
02:07 PM travis_farmer: yeah, pretty much
02:08 PM travis_farmer: brb, gotta run
02:10 PM travis_farmer: ... false alarm, didn't have to run (person wasn't home...)
02:11 PM travis_farmer: proper term would be a self-managed enterprise-worthy solution
02:18 PM NoGodDamnIdea: hey guys
02:18 PM NoGodDamnIdea: update bjorkintosh it was the lens, they got damaged during the first cuts
02:24 PM bjorkintosh: ah
02:25 PM bjorkintosh: that would do it.
02:25 PM bjorkintosh: so now you have clean lenses and clean mirrors?
02:41 PM roycroft: no, not at all, tom_l
02:41 PM roycroft: in fact it's the opposite
02:42 PM Tom_L: opposite?
02:42 PM Tom_L: oh gitlab
02:42 PM roycroft: while it can be self-hosted, it takes the functionality of github and adds a lot of other collaboration tools for project groups to use
02:43 PM roycroft: yes
02:43 PM roycroft: as i've said, i don't use any of the extra features of gitlab
02:43 PM roycroft: i installed a github server and did not like the user interface
02:43 PM roycroft: gitlab has a nice web interface that makes my life easier
02:44 PM roycroft: i use the web interface to create projects and organize projects
02:44 PM roycroft: but i use the standard git tools to manage my individual repositories
02:45 PM Tom_L: takes alot of space though?
02:46 PM XXCoder: nvme prices is crashing
02:46 PM XXCoder: so good time to buy em from what i understand
02:46 PM XXCoder: dont buy 970 980 or 990 though, they have bad habit of dying
02:47 PM Tom_L: is that the m.2 stuff?
02:47 PM XXCoder: nvme drives
02:47 PM Tom_L: i think mine is older than those
02:47 PM roycroft: that depends on the repositories
02:47 PM Tom_L: 960 maybe
02:47 PM Tom_L: i dunno for sure
02:47 PM XXCoder: system information show show what it is
02:48 PM Tom_L: it's not installed on anything atm
02:48 PM roycroft: my gitlab server is a 30GB virtual machine
02:48 PM XXCoder: 970 is what I have, it is start of problemic drives but lasts a while. 980 and later is much worse
02:48 PM Tom_L: maybe on my spare mb
02:48 PM roycroft: it nfs mounts the repository from my nas
02:49 PM roycroft: my repository is currently about 75GB
02:49 PM Tom_L: did that iso work for you?
02:49 PM roycroft: oh, no, it didn't
02:49 PM roycroft: it partially installed but then it insisted on loading some packages from a debian mirror that are no longer available
02:50 PM roycroft: it was better than the net install iso, but it did not have enough
02:50 PM Unterhausen: nvme didn't go down much from the last time I bought one a month ago
02:50 PM Unterhausen: it was dirt cheap though
02:50 PM roycroft: i'm actually looking at using a different software package now that is not abandonware and doesn't need ancient stuff like php5
02:50 PM roycroft: i found something that kind of works, and maybe i can get to work better
03:01 PM Tom_L: XXCoder, are those numbers generic or specific to samsung?
03:01 PM CaptHindsight: Tom_L: Libera is still working with Matrix to secure how matrix and Discord accounts are allowed to access IRC. I already see changes in how account names are being tied to specific users
03:03 PM Tom_L: or don't teach
03:03 PM Unterhausen: they wanted to tax people until the law could be changed
03:03 PM Unterhausen: there was a really unfair tax, so the rate was changed to zero
03:03 PM Tom_L: taxes are supposed to be fair?
03:05 PM roycroft: they are supposed to be, but they aren't
03:06 PM roycroft: zero was not a number until the arabs invented it
03:10 PM Tom_L: we have to keep it or binary numbers would be rather awkward
03:10 PM XXCoder: 1nothing1nothingnothing1nothing
03:12 PM Tom_L: nil for shorthand
03:13 PM XXCoder: just glad we arent using roman numbers
03:14 PM roycroft: i'm happy that the zero was invented
03:15 PM roycroft: it makes math easier, and thus, makes life easier
03:15 PM XXCoder: im sure there would have been invention of numbering system besides romans if arabian number system never existed, but yeah its awesome
03:15 PM roycroft: my neighbors across the street are having a big garage sale today
03:15 PM roycroft: my driveway has been completely blocked most of the day
03:15 PM roycroft: it's a good thing i don't have to go anywhere urgently
03:16 PM XXCoder: why would they setupo on your land?
03:16 PM * roycroft doesn't get how folks think they can park blocking someone's driveway
03:16 PM roycroft: it's not the garage sale that's blocking it
03:16 PM XXCoder: ah parked cars
03:16 PM roycroft: it's the garage sale customers
03:16 PM roycroft: yeah, they park right in front of my driveway
03:16 PM roycroft: and as soon as they leave, another car parks in front of the driveway
03:17 PM roycroft: i mean, i get it - it's a pretty big garage sale, and there are like 30 cars parked here at any given time
03:17 PM roycroft: but folks still should not block driveways
03:17 PM roycroft: mine's not the only one that is blocked
03:17 PM XXCoder: if I saw a driveway I would park elsewhere
03:17 PM roycroft: yeah, even if it was a block away
03:17 PM XXCoder: man up and walk
03:18 PM roycroft: they're blocking the mailboxes too, and i have a parcel arriving today
03:19 PM roycroft: the letter carriers don't even stop if the mailbox is blocked - they just drive on to the next set of mailboxes
03:20 PM XXCoder: sucks :(
03:27 PM Tom_L: so back something up in the drive so they can't use it
03:30 PM roycroft: i do have some errands to run, but i was already planning on doing them late this afternoon
03:30 PM roycroft: i presume the garage sale will be over for the day by 3 or so - that's when most of them wind down
03:43 PM CaptHindsight: there were 0 Arabs before they invented it
03:45 PM CaptHindsight: roycroft: sounds like a good time to get out the weed wacker and leaf blower to spread that pea gravel around the perimeter of your driveway
03:45 PM CaptHindsight: "I'm just landscaping"
04:10 PM CaptHindsight: https://youtu.be/rk7N8HPNehw?si=lxWebxHUXrV82Wi9&t=308
04:13 PM travis_farmer: dad is a little short of breath, with pain in his back... mom is taking him to ER for a check...
04:13 PM CaptHindsight: hope things go well
04:13 PM travis_farmer: same here
04:14 PM CaptHindsight: BP meds do similar to me
04:15 PM travis_farmer: all he was doing is moving a couple saw horses...
04:44 PM XXCoder: yeah definitely check that. good that hes going
05:04 PM -!- #linuxcnc mode set to +vv by ChanServ
05:34 PM solarwind: I don't understand why the sanding belts for my air belt sander keep breaking at the taped joint well before the sanding grit wears oujt
05:34 PM solarwind: Doesn't matter which brand I buy. They all just snap after a few minutes of use
05:34 PM solarwind: I save them of course so I can tape them back together once I find the right type of tape
05:36 PM XXCoder: overtightening?
05:36 PM solarwind: I don't think so, it's this: https://www.astrotools.com/product/air-belt-sander-1-2-x-18-with-3pc-belts-40-60-80/
05:36 PM solarwind: One thing to note though: the original belt that came with it lasted forever and did not snap.
05:37 PM solarwind: The tension is controlled by a spring. I don't think it's adjustable, but it
05:37 PM solarwind: it feels about right
05:39 PM XXCoder: not sure then
05:47 PM travis_farmer: update on dad: running some tests, ekg, x-ray, covid, but nothing else so far for info...
05:55 PM CaptHindsight: solarwind: fool the sander, place tape at several places on the belt
05:56 PM solarwind: CaptHindsight normal tape doesn't cut it, it has to be fibreglass strand reinforced tape or similar
05:57 PM CaptHindsight: oh it's not wide, run the tape along the opposite side of the sand
05:57 PM CaptHindsight: is the adhesive on the tape melting?
05:58 PM Tom_L: belt abuse!
05:58 PM CaptHindsight: or is the polymer tearing?
05:58 PM solarwind: No, it's not tearing. The adhesive just seems to be not strong enough
05:58 PM XXCoder: is belts specifically for that tool?
05:59 PM solarwind: They're standard sized belts
05:59 PM XXCoder: it would have to stand up to pretty tight radius turn
05:59 PM CaptHindsight: Free Speed: 16,000 rpm
05:59 PM solarwind: Yes, it's fast and aggressive. I love it
05:59 PM CaptHindsight: pretty fast for a belt
06:00 PM solarwind: And yes the radius on the front roller is tight
06:00 PM CaptHindsight: that might be for the drive pulley
06:00 PM solarwind: YOu can hear the adhesive coming off while you're using the belt, so you can prepare yourself for the inevitable *snap*
06:00 PM Tom_L: 1/2" wide?
06:00 PM solarwind: yes
06:00 PM solarwind: It's a common tool
06:00 PM CaptHindsight: circum france
06:01 PM CaptHindsight: ~6"
06:02 PM CaptHindsight: ~5300 inches per minute belt speed max
06:03 PM Tom_L: find a wider 3m belt like this https://www.amazon.com/Cubitron-3M-33437-File-Belt/dp/B00PB3OAJI?th=1
06:03 PM Tom_L: longer as well
06:03 PM solarwind: That's not wider, that's the right size
06:03 PM Tom_L: you said 1/2"
06:04 PM CaptHindsight: 1/2 in x 18 in
06:04 PM solarwind: But yeah I'll try the cubitron. I've always had success with 3M stuff
06:04 PM solarwind: 1/2" x 18" is the right size
06:04 PM CaptHindsight: " they do a way better job than similar ones sold at discount tool locations - Harbor Freight or Princess Auto."
06:05 PM Tom_L: https://www.amazon.com/Cubitron-3M-33445-File-Belt/dp/B00PB3OFDY
06:05 PM solarwind: Fine belts and low pressure at that speed is a very fast way to get a mirror like polish on edges
06:06 PM Tom_L: fine grit probably generates more heat too
06:07 PM solarwind: Yeah, heat could be a reason the tape is peeling off
06:07 PM XXCoder: grind it on something for some time then checkj heat
06:07 PM CaptHindsight: https://www.mscdirect.com/product/details/05220066
06:07 PM XXCoder: dont forget that flexing tape also makes heat
06:07 PM solarwind: XXCoder I did, it's always warm enough to touch (the belt, that is)
06:08 PM solarwind: the workpiece is of course always hot but that goes for any sanding/grinding operation
06:08 PM CaptHindsight: https://www.mscdirect.com/browse/tn/Abrasives/Coated-Non-Woven-Abrasives/Belts/Abrasive-Belts?navid=2100147&refinements=In+Stock%3AYes--Belt+Width+%28Inch%29%3A1%2F2--Belt+Length+%28Inch%29%3A18
06:08 PM Tom_L: 3m usually has good stuff
06:08 PM solarwind: I appreciate 3M's very non-flashy factual advertising/specs
06:08 PM solarwind: they may be a criminal organization, but at least I can trust their specs
06:09 PM CaptHindsight: "now with duragrit 5000"
06:13 PM CaptHindsight: https://www.youtube.com/watch?v=u0_TsgZ1Sr8
06:14 PM CaptHindsight: The two main factors that seemed to make the join let go was the glue softening from the heat generated as the belt flexing over the rollers or from the actual friction of metal removal (You already seem to be on top of that with the heat resistant contact adhesive), and not having the belts 100% straight. If it's even slightly out of line the join will start coming apart from the tightest edge.
06:15 PM solarwind: The alignment seems to be perfectly straight as far as my eyes can tell
06:16 PM solarwind: So then it must indeed be the heat. I did notice sanding plastic (PETG) 3D prints resulted in much less belt failure than metal
06:17 PM solarwind: That time Tom_L made fun of me for getting the 2nd degree burn was indeed when I was sanding it with this very tool and let it get that hot

06:18 PM solarwind: But damn, 3M costs $5/belt. That's as much as their cubitron flap discs and I know for sure those last a very very long time
06:20 PM XXCoder: making own belts interesting
06:20 PM CaptHindsight: https://www.youtube.com/watch?v=1lE1KbKx9xA uses epoxy on the seam
06:21 PM XXCoder: I was really unsure what he was doing with superglue and gluing to wod
06:21 PM solarwind: seems like I'm not the only one with this issue
06:21 PM solarwind: The wide (3"+) sanding belts seem not to have this problem
06:21 PM CaptHindsight: delaminate the tape
06:22 PM CaptHindsight: bond the fabrics
06:22 PM solarwind: I don't understand why they don't use a longer piece of tape...

06:24 PM solarwind: Yeah that looks exactly like what they use on the astro belts which are supposed to be better than the generic chinese ones

06:24 PM solarwind: But then again, I seek out zirconia belts specifically
06:25 PM solarwind: Blue for P36 P40 P60 sanding belt ... why different colours for different grits?
06:25 PM Tom_L: 3m does that on their sanding pads too
06:26 PM Tom_L: white, maroon, green etc
06:27 PM Tom_L: https://www.3m.com/3M/en_US/metalworking-us/products/flat-stock/hand-pads/
06:28 PM solarwind: I think that's for a different reason
06:28 PM Tom_L: could be
06:28 PM solarwind: I was talking about the splicing tape specifically
06:28 PM Tom_L: ahh i missed that
06:30 PM roycroft: different colors for different grits makes it easy to grab the right one
06:31 PM solarwind: Yes, but why are different ones needed in the first place?
06:32 PM solarwind: Well, time to test the theory, I'll just leave the tool idling on low speed and see how long before the belt breaks if at all
06:32 PM solarwind: Then full speed, then with a heat gun pointed at the belt
09:12 PM XXCoder: blondihacks automatically transcripted: bloody ax hacks
10:30 PM skunkworks: went on vacation for a week - north from us about 3 hours.
10:31 PM skunkworks: The weather up there was awesome - 80's while the weather at home was 100f or more
10:31 PM skunkworks: got home - stepped in the house and it was hot.. about 10 degrees above the central air..
10:31 PM skunkworks: the outside unit fan was running - but the compressor wasn't
10:32 PM skunkworks: This thing is from the 80's - I really though it finally cooked. (well - it still might be on its last legs)
10:33 PM skunkworks: but - alas - it was the capasitors.. (it had a 30 and a 15uf in parallel..) I found a 40uf one at work - and whew - the compressor started up.
10:35 PM skunkworks: I also cleaned out the coils - I probably should have done that a while ago.. You can't really see them - but I had most of the tin off the outside - and it was pretty plugged.
10:36 PM XXCoder: whew heh
10:37 PM skunkworks: I was thinking it was time for a mini split
10:38 PM skunkworks: my exact words where holy fuck!
10:38 PM skunkworks: wow - been running for about an hour - and it already is feeling better in here
