[03:20:11] <pink_vampire> but I don't want to get some junk
[03:20:30] <pink_vampire> also can someone identify this lathe? https://i.imgur.com
[03:22:40] <roycroft> a glass scale dro would be the most durable and accurate type
[03:22:59] <roycroft> don't get a harbor freight digital caliper type
[03:32:09] <pink_vampire> what will be the fastest?

[05:21:56] <andypugh> pink_vampire: It’s a lathe.
[05:22:34] <andypugh> (Or did you want more than that?)
[05:22:35] <XXCoder> hey andy
[05:25:44] <andypugh> I’m not here. :-)
[05:25:58] <andypugh> (Just swapped from work to home computer briefly)
[05:27:32] <XXCoder> wow for guy thats not here, youre very,,, here
[05:28:04] <XXCoder> ;)
[06:03:30] <pink_vampire> andypugh: yeah.. like what model it is
[06:03:43] <JT-Cave> morning
[06:03:47] <XXCoder> hry jt
[06:03:55] <pink_vampire> hi JT-Cave
[06:04:03] <XXCoder> apparently someone at work got covid so today I didnt work
[06:04:12] <XXCoder> shop was compleely empty wow
[06:04:32] <XXCoder> talked to boss and found that he told me that shop is closed for today

[07:06:17] <Tom_L> morning
[07:10:35] -!- Centurion_Dan has quit [Ping timeout: 240 seconds]
[07:19:39] <Tom_L> XXCoder, they have to disinfect the whole shop
[07:19:54] <XXCoder> yep thats why it was closed today
[07:20:56] <Tom_L> technically they make all the workers get tested and quarantine 14 days before they can reopen
[07:21:19] <XXCoder> seems not the case
[07:22:11] <Tom_L> they _could_ just isolate his work area and have them tested
[07:22:56] <XXCoder> maybe i dont know who tested postive
[07:23:12] <Tom_L> possibly, they're not allowed to disclose that
[07:23:20] <Tom_L> hipa laws
[07:23:22] <XXCoder> yep know that
[07:23:27] <XXCoder> though i might be able to guess
[07:23:39] <XXCoder> unless its office guy who goes to back all time
[07:23:47] <Tom_L> they were very quiet about it at my kid's work

[12:31:52] <roycroft> so i have a taiwanese woodworking machine that was missing a bunch of fasteners, all metric
[12:32:18] <roycroft> i had most of them in stock, and was easily able to find the rest locally, except for one - there was a single m5-1.5 lht hex nut missing
[12:32:46] <roycroft> i chased all over town for that, and finally found one, for which i got to pay $9 for the single nit
[12:32:54] <roycroft> and it's m8-1.5, not m5-1.5
[12:33:02] <roycroft> except when i got home it wasn't m8-1.5
[12:33:10] <roycroft> it was actually 5/16-18 lht
[12:33:22] <roycroft> the m8 nut *almost* fit
[12:33:54] <roycroft> and had i measured more carefully i'd have known what it was up front, but since literally every other fastener on the machine was metric, it seemed safe to assume that it was also metric
[12:34:06] * cpresser laughs in metric
[12:34:07] <roycroft> 5/16-18 lht nuts are fairly easy to find
[12:34:37] <t4nk_freenode> buy local!!!!
[12:34:41] <t4nk_freenode> (lol)
[12:34:51] <t4nk_freenode> (they need our support!!)
[12:34:56] <roycroft> unfortunately, the $9 one that i bought is from my least favorite local supplier, it's a long drive to get to them, and they charge a 20% restocking fee, with a minimum fee of $10
[12:35:08] <roycroft> it would cost me more to return it than what i paid for it
[12:35:13] <JT-Cave> what's fun on some older machines made in Taiwan is discovering they used Whitworth
[12:35:38] <roycroft> i guess some day i might need an m8-1.5 lht nut and i won't have to do this again
[12:36:01] <roycroft> whitworth hasn't been used in the west since wwii
[12:36:15] <roycroft> when we unified the british and us standards
[12:36:59] <roycroft> i guess all that whitworth tooling had to go somewhere
[12:37:17] -!- Valen has quit [Ping timeout: 260 seconds]
[12:37:18] <t4nk_freenode> heh, yeh, I first heard the term whitworth... from my grandparents ;)
[12:38:41] <roycroft> during the war we discovered that british and american fastners were almost interchangeable, but not quite, and since it would be so benificial to be able to pool/share resources, the unified standard came about
[12:46:10] -!- Valen has joined #linuxcnc
[12:51:26] <gregcnc> make the required nut?
[12:53:48] <gregcnc> would have been a lot more fun to make the metric and find out if was wrong.
[13:08:13] -!- Loetmichel_ has joined #linuxcnc
[13:09:59] <CaptHindsight> I have to check every fastener I buy at the ACE or Home Depot since they are usually not it the correct bins and if bagged sometimes a different thread than marked

[13:21:15] <CaptHindsight> t4nk_freenode: https://www.amazon.ca
[13:23:56] <t4nk_freenode> Nicknocks storefront
[13:23:57] <t4nk_freenode> 3 out of 5 stars53% positive in the last 12 months (64 ratings)
[13:24:35] <t4nk_freenode> 30 days Negative 100%
[13:24:38] <t4nk_freenode> ;)
[13:28:17] <CaptHindsight> ReeJekd
[13:29:28] <t4nk_freenode> wow, CaptHindsight ... some store you found there...
[13:29:29] <t4nk_freenode> https://www.aliexpress.com
[13:29:54] <t4nk_freenode> twice as expensive as ali
[13:30:56] <t4nk_freenode> ali has free ae shipping, nicknocks just uses cainiao hehe
[13:31:31] <t4nk_freenode> plus.. all the amazon victims will be unpleasantly surprised by customs fees
[13:32:11] <t4nk_freenode> though on the other hand: not many ppl actually seem to have received their package at all
[13:32:22] <CaptHindsight> shipping surprise vs surprise shipping
[13:32:30] <t4nk_freenode> hehe
[13:33:14] <CaptHindsight> 3 weeks from China via SpeedPak was my latest
[13:34:07] <CaptHindsight> sent USPS priority to Germany and it's 2+ months already
[13:34:45] <t4nk_freenode> isn't that quite the expensive of shipping options? must be quite expensive
[13:35:27] <CaptHindsight> small box ~16oz
[13:35:35] <t4nk_freenode> I orders from 2 ali stores last week, today I got a mail that the packages have arrived 'in my country'
[13:35:38] <CaptHindsight> .5kg
[13:36:39] <Tom_L> i laugh at companies that make shipper labels to make you think their junk has shipped then wait a few days to actually kick it out the door
[13:38:33] <t4nk_freenode> I detest that
[13:38:35] <t4nk_freenode> bah
[13:39:32] <CaptHindsight> I paid for 2 day shipping why did it take a week?
[13:39:45] <CaptHindsight> Because it shipped on day 5
[13:40:01] <t4nk_freenode> I ordered some rosin, paid a bit more because they promised trackable, faster aliexpress shipping...
[13:40:13] <t4nk_freenode> bastard sent the package through cainiao
[13:40:24] <CaptHindsight> ooops
[13:40:29] <t4nk_freenode> 16 Apr 2020 19:50 Accepted by carrier
[13:40:36] <CaptHindsight> sorry do you want to return?
[13:40:41] <t4nk_freenode> 23 May 2020 17:23 Arrive at destination country
[13:40:50] <t4nk_freenode> Days in transit 89
[13:40:50] <veegee> CaptHindsight one of my forklifts has 6" forks and the other has 4" forks. I'm getting extensions. It's ok to get the wider ones that fit the 6" forks and use them on the smaller 4" forks right?
[13:41:19] <Tom_L> sneeze in the box and send it back to em
[13:41:24] <t4nk_freenode> I don't really think the package will ever come... already got my refund through a dispute
[13:41:35] <t4nk_freenode> yeh, exactly CaptHindsight ... 'oops'
[13:41:41] <t4nk_freenode> really, so low ;)
[13:41:50] <CaptHindsight> veegee: if you can keep them from sliding around
[13:42:20] <veegee> I guess I can make some padding for the 4" forks
[13:42:52] <CaptHindsight> veegee: you don't want a load coming loose
[13:43:01] <veegee> That's what she said
[13:43:02] <veegee> (sorry)
[13:43:11] <veegee> https://www.mrdockplate.ca
[13:43:38] <veegee> They're cheap enough, not worth the hassle, I can just get a dedicated pair for each forklift
[13:44:32] <Tom_L> don't get em so long they tip the forklift over
[13:44:38] <veegee> Hmm, 6, 7, or 8 ft?
[13:44:49] <veegee> 8 ft super useful for getting things out of a trailer
[13:45:02] <Tom_L> better get some counterweights too
[13:45:06] <CaptHindsight> center of mass
[13:45:17] <veegee> I'm not lifting anywhere near that much on a regular basis
[13:45:26] <Tom_L> just takes once
[13:45:27] <CaptHindsight> derate load capacity
[13:45:33] <veegee> Usually less than 1,000 lbs
[13:45:37] <veegee> like 500lb loads
[13:46:08] <veegee> Biggest downside of long forks is can't go up against a wall
[13:46:11] <Tom_L> and you say this is a hobby?
[13:46:15] <veegee> indeed
[13:46:42] <veegee> I balance my life, 6 hours of work at the office, rest of day at workshop
[13:46:51] <Tom_L> i'm gonna start a go fund me just for you
[13:47:08] <veegee> People blow $200 on stupid shit like clothes
[13:47:19] <veegee> Forklift extensions can be sold and will last forever
[13:47:36] <veegee> I almost always buy used items too for 20% of original cost. That's how I'm able to do all this
[13:47:46] <veegee> 'And my monthly rent is $1,500, less than what my employees pay for their apartments
[13:47:56] <veegee> not nearly as expensive as what people think
[13:48:17] <veegee> I bought the forklift for $4,000. People blow that on a TV
[13:48:26] <Tom_L> not this ppl
[13:48:27] <CaptHindsight> please no rants today :)
[13:48:34] <Tom_L> awwwww
[13:48:36] <veegee> Not a rant, just saying
[13:48:56] -!- veek has quit [Quit: Leaving]
[13:49:06] <Tom_L> i'm all for it
[13:49:13] <Tom_L> if you can pull it off
[13:49:23] <CaptHindsight> no coffee yet today
[13:49:32] <veegee> I guess I'll start with the 8ft extensions. Great for lifting 4x8 plywood
[13:50:50] <jymmmm> You know what really annoys me.... Peeople that whine about rants yet haven't had their coffee yet?! Like, WTH, you know what the problem is, so.... GIT ER DONE and quit whining about ranting you ranting whiner!
[13:51:20] <veegee> Ok off to get the extensions. I love you all <3
[13:51:46] <Loetmichel> Jymmm: did so: http://www.cyrom.org
[13:51:50] <Loetmichel> :-)
[13:52:19] <Tom_L> jymmmm, i'm not even a coffee drinker so wtf am i supposed to do???
[13:52:46] <Loetmichel> it was indeed the exposure that was wrong. black resin needs more than 8 secs (14) and less than 0.1mm layer height (0.05mm)
[13:52:52] <jymmmm> Loetmichel: refresh my memory
[13:52:56] <Loetmichel> aaaand it works after three failues
[13:53:19] <t4nk_freenode> CaptHindsight, .... for 50euro's.. that oscilloscope doesn't seem too bad, does it?
[13:53:21] <jymmmm> Tom_L: drugs? weed? peote? adrelalin? tea?
[13:53:32] <Loetmichel> the result of me doing overtime because i dont learn to NOT start a print short of end of work for the day
[13:53:43] <Loetmichel> (is there an english word for "feierabend"?)
[13:53:53] <CaptHindsight> Dear Sirs, (and Jym) 3rd party whining about rants about whining are no longer acceptable unless spoken with a strong accent. Please rephrase and uncheck spelling. Sincerely, The management.
[13:53:59] <jymmmm> Loetmichel: Ah, you using a rPi?
[13:54:14] <jymmmm> CaptHindsight: yo momma!
[13:54:20] <Tom_L> Loetmichel, end of work day
[13:55:11] <Loetmichel> no, its a Elegoo Mars resin 3dprinter. it doesent have a usb serial port
[13:55:25] <Loetmichel> so an octopi would be useless
[13:55:34] <Loetmichel> i simply carried the file per usb drive
[13:55:38] <Tom_L> put a camera on it and go home
[13:55:49] <jymmmm> Loetmichel: Oh, um, maybe attach a tiny clock to the printer and a sticker that says "Quitting time?"
[13:55:54] <Loetmichel> resin doesent like to sit in the vat all night
[13:56:10] <Loetmichel> @ Tom_L
[13:56:43] <CaptHindsight> thinking about making an aeropress from cast iron
[13:56:44] <jymmmm> Loetmichel: they look decent for being printed
[13:57:06] <jymmmm> CaptHindsight: like a comPRESSer ?
[13:57:16] <t4nk_freenode> Loetmichel, I think you were quite close with 'end of work', 'end of shift', perhaps 'head home for the evening' might also work
[13:57:22] <jymmmm> <rim shot in an indian accent>
[13:58:07] <CaptHindsight> Loetmichel: what happened to the resin over night?
[13:59:06] <Loetmichel> CaptHindsight: nothing, but it MIGHT harden if you let it sit in a company that has flourescent lights on the ceiling all night
[13:59:16] <Loetmichel> nothing yet
[13:59:17] <CaptHindsight> Loetmichel: doesn't it have wifi?
[13:59:23] <Loetmichel> i simply didnt want to risk it
[13:59:40] <CaptHindsight> yeah, throw a dark blanket over it
[14:00:06] <Loetmichel> nope, the elegoo mars has no wifi and no usb device (only host for flash drives) and no rj45 either
[14:00:20] <Loetmichel> its an $200 UV resin printer...
[14:00:44] <CaptHindsight> yeah there are many versions of that printer
[14:01:04] <CaptHindsight> I posted the link the the controllers the other day
[14:01:09] <Loetmichel> standard NEW elgoo mars.
[14:01:15] <Loetmichel> i already looked inside.
[14:01:18] <Loetmichel> it has the new board
[14:01:23] <Loetmichel> no more rj45 ;)
[14:02:22] <CaptHindsight> featuring closed source software, so you can't share files
[14:03:25] <CaptHindsight> someone sent us one a few years ago before they launched to test resins
[14:03:40] <Loetmichel> i am not complaining
[14:03:54] <Loetmichel> to test out the "UV resin printing" waters its cheap enough
[14:04:15] <Loetmichel> if it works reasonably well for us we may get a couple bigger ones with wifi and so on.
[14:04:18] <CaptHindsight> can always convert to LCNC
[14:04:42] <Loetmichel> that wouldnt make sense for an UV printer with LCD
[14:04:47] <Loetmichel> it isnt laser based
[14:04:54] <Loetmichel> it has exactly ONE stepper motor
[14:05:12] <CaptHindsight> no, just LCD with 405nm-ish leds behind it
[14:06:05] <Loetmichel> indeed
[14:06:09] <Loetmichel> ONE led
[14:06:12] <Loetmichel> but a 10W one ;)
[14:06:20] <CaptHindsight> nobel.1 was laser https://ibin.co
[14:06:27] <Loetmichel> or even more, it gets pretty hot
[14:09:27] <CaptHindsight> https://imgur.com 500W led powered
[14:11:00] <CaptHindsight> the formlabs are also laser and galvo
[14:11:21] <CaptHindsight> everyone else is LCD bottom up
[14:14:29] <jymmmm> How would YOU connect these together? https://www.youtube.com
[14:15:16] <jymmmm> I'm not too concerned about galvonic whatchamacallit
[14:16:24] <Loetmichel> eihter spotwelding a copper/nickel tab on or pressing it between two copper strips that "grip" the alu with small teeth and are screwed on
[14:16:45] <Loetmichel> i wouldnt cut out any of the alredy small tab thats still there
[14:17:19] <jymmmm> spot welding doesn't seem to work, or is weak, many tried

[14:18:31] <Loetmichel> then get some 15*3 copper bar, mill 90° teeth on one side, a series of holes on the other for small screws, use the screws to press the remaining alu tab into a "zigzag" shape with two of those bars
[14:19:07] <Loetmichel> then use one or more of the screws to connect approbiatly thick copper wire
[14:19:42] <Loetmichel> s/side/half of the 15mm width
[14:19:46] <jymmmm> https://www.youtube.com
[14:20:03] <Loetmichel> at least thats what i would do
[14:21:03] <Loetmichel> a) he uses WAY not enough screws
[14:21:21] <Loetmichel> b) dont grab the foil pack, just the tab
[14:21:56] <Loetmichel> c) use teeth on the connecting bar on BOTH sides so the alu oxide on top is cut by bending
[14:22:15] <Loetmichel> d) his upper "lid" is WAY to thin
[14:22:42] <Loetmichel> <- can be a bit pedantic sometimes ;)
[14:23:18] <jymmmm> I was thinking 1/16" thick 1/2" wide alum bars, slightly bowed in the middle liek thise (sideways) ---> )( so when bolted together x2, it will sandwich the middle of the tabs
[14:24:13] <Loetmichel> yeah, still would use about 5 screws o those packs
[14:24:35] <Loetmichel> and some "teeth" on the bars so that they "bite" into the tab
[14:24:56] <Loetmichel> also make the bars wide enough that the screws are NOT inside the tab but above it
[14:25:24] -!- gloops has joined #linuxcnc
[14:25:25] <Loetmichel> so that the "toothed" part of the bars is without any holes that weaken the already weak tab even more
[14:25:39] <Loetmichel> just so you know my reasoning
[14:26:32] <jymmmm> Eh, I don't really want modify the tabs with more holes
[14:27:04] <Loetmichel> yes, exactly

[14:45:18] <CaptHindsight> adjust the thickness of each shelf to conduct heat to a spreader
[14:47:04] <CaptHindsight> my design would work, but nobody makes this, yet
[14:48:18] <CaptHindsight> if max density is not a concern then you could have air space between cells
[14:48:51] <CaptHindsight> or have them radially spread

[15:10:00] <roycroft> hey folks
[15:10:11] <roycroft> i have an air compressor with a bit of a problem
[15:10:14] <roycroft> more an annoyance
[15:10:30] <roycroft> it has a 5hp motor, and it's on a 20a circuit, which is fine most of the time
[15:10:38] <roycroft> but sometimes the startup current pops the breaker
[15:11:12] <roycroft> it's neither feasible to increase the capacity of the circiut nor do i want to - i'd like it to still trip on a 20a load most of the time
[15:11:35] <roycroft> could this be solved by putting a capacitor inline to store some extra current for startup?
[15:11:44] <roycroft> safely and reasonably
[15:12:57] <jymmmm> roycroft: voltage?
[15:14:01] <CaptHindsight> No
[15:14:18] <roycroft> 240vac
[15:14:27] <roycroft> i thought probably not, capthindsight
[15:14:48] <jymmmm> roycroft: $225 https://www.briskheat.com
[15:14:51] <CaptHindsight> maybe a clutch
[15:15:28] <CaptHindsight> no load when starting then the clutch slides to engage
[15:15:39] <roycroft> the circuit should handle a 5hp motor just fine - 240vac@20a~=6.25hp
[15:15:58] <CaptHindsight> the breaker could be old
[15:16:05] <roycroft> it's just on startup
[15:16:11] <CaptHindsight> a new breaker might just solve this
[15:16:24] <CaptHindsight> they have limited life
[15:16:32] <roycroft> i can run the motor for a long time without tripping it
[15:16:40] <roycroft> yes, i know they have limited life
[15:16:43] <jymmmm> inrush
[15:16:47] <roycroft> and this one has tripped many times over the years
[15:16:51] <roycroft> probably hundreds
[15:17:01] <roycroft> but it was like this when i first installed it
[15:17:10] <gregcnc> Is the wiring spec different for installing a longer starting current breaker as used on A/C compresors
[15:17:11] <jymmmm> CaptHindsight: WHAT?! YOu mean my screw in 120V fuses won't last forever?
[15:17:20] <roycroft> i'll look into that soft starter
[15:17:25] <gregcnc> i forget the classification? D or siomethisn?
[15:17:29] <roycroft> the issue isn't really so much the compressor
[15:17:48] <roycroft> it's that i took a feed off that circuit to my belt grinder, which is in a different shop
[15:17:57] <jymmmm> roycroft: Look around, that was a 1st search result. I do know they use them on RV AC units to be able to run on smaller generators
[15:18:12] <CaptHindsight> check all the connections and tighten
[15:18:13] <roycroft> i never use air and the belt grinder at the same time - the compressor has never run at the same time as the belt grinder
[15:18:24] <CaptHindsight> use thicker wire for lower voltage drop
[15:18:36] <roycroft> but the breaker is about 1m away from the compressor, which is why i never bothered to fix this in the past
[15:18:38] <roycroft> it was no big deal
[15:18:43] <roycroft> but the belt grinder is in a different shop
[15:18:46] <CaptHindsight> might be a bunch of little things adding up
[15:18:57] <roycroft> and when i go out there to use it and there's no power i have to go back to the main shop to reset the breaker
[15:18:58] <jymmmm> roycroft: what gauge wire to the compressor now?
[15:18:59] <roycroft> which annoys me
[15:19:07] <roycroft> 10ga, i think
[15:19:26] <roycroft> actually, it's 6ga to the subpanel
[15:19:32] <roycroft> and 10 or 12ga to the compressor
[15:19:34] <gregcnc> unloader valve is present and working?
[15:19:34] <roycroft> i forget which
[15:19:36] <roycroft> probably 12ga
[15:19:39] <roycroft> the unloader is working
[15:19:44] <jymmmm> double it? parallel the 10ga to the compressor maybe?
[15:19:47] <roycroft> i have replaced it in the past
[15:20:00] <roycroft> it's less than a meter from the breaker to the compressor switch
[15:20:15] <roycroft> the wire gauge is not the problem
[15:21:22] <jymmmm> It won't hurt anything, especially if it's 12ga now
[15:21:24] <roycroft> the one time a long time ago that i thought it might be an unloader issue i replaced it, and nothing changed
[15:21:27] <jymmmm> cheap enough too
[15:21:38] <roycroft> it's totally not necssary over that short a run
[15:22:06] <roycroft> but i might verify that the wires are making good contact to the switch
[15:22:08] <jymmmm> roycroft: do you have a clamp in amp meter?
[15:22:11] <roycroft> and to the breaker
[15:22:12] <roycroft> yes
[15:22:29] <jymmmm> does it have a peak hold? Maybe measure the inrush at startup
[15:22:31] <roycroft> i'll go measure it some time when the compressor starts up
[15:22:38] <roycroft> i don't think it has a peak hold, but i'm not sure
[15:22:49] <roycroft> i'd also have to find somewhere to clamp it on
[15:23:03] <roycroft> the wires are thhn, running in flex metal conduit
[15:23:10] <roycroft> i'm not sure i'd get a good reading from that
[15:23:15] <jymmmm> tinside the sub panel?
[15:23:22] <roycroft> not much room there
[15:23:26] <jymmmm> ah
[15:23:30] <roycroft> it's not a standard subpanel
[15:23:36] <jymmmm> gotcha
[15:23:38] <roycroft> it's a hot tub panel
[15:23:56] <jymmmm> roycroft: Do you have 10Ga laying around?
[15:23:59] <roycroft> there's a 60a gfci breaker, a 20a 240vac breaker, and a couple 20a 120vac breakers
[15:24:03] <roycroft> yes, i have plenty
[15:24:18] <roycroft> but 12ga is rated at 30a for short runs
[15:24:21] <roycroft> er
[15:24:22] <roycroft> 20a
[15:24:25] <roycroft> which is what i have
[15:24:37] <roycroft> so over a 1m run it should be just fine
[15:24:45] <gregcnc> 1meter between breaker and compressor?
[15:24:50] <roycroft> it should handle 30m with no appreciable voltage loss
[15:24:53] <roycroft> yes
[15:25:01] <jymmmm> Right, but if the inrush is 40 or 60A, you might get some loss
[15:25:02] <roycroft> but i'll measure voltage at the compressor switch
[15:25:37] <gregcnc> and why hasn't the wire and outlet been upgraded?
[15:25:43] <roycroft> if the existing wires are 12ga i'lll replace them wiht 10ga
[15:25:56] <roycroft> there is not an outlet
[15:26:01] <roycroft> it's hard-wired to the breaker box
[15:26:07] <roycroft> and there should be no need to "ugprade"
[15:26:24] <jymmmm> roycroft: I'm just saying that replacing the wire is a cheaper attempt than a new break, and wont hurt anything, and you can leave in a little extra to be able to clamp on your meter
[15:26:33] <gregcnc> but it has never worked correctly?
[15:27:07] <roycroft> the motor is rated at 16a
[15:27:12] <roycroft> the breaker is 20a
[15:27:15] <gregcnc> inrush current is a real thing
[15:27:20] <CaptHindsight> if it's belt drive you can also change the pulleys
[15:27:40] <roycroft> that would be outrageously expensive
[15:28:03] <roycroft> the motor sheaves are already tiny - i'd not want to make them any smaller
[15:28:14] <roycroft> and the pump sheaves are about 16" in diameter already
[15:28:55] <roycroft> jymmm: i'll check to see if it's 12ga or 10ga
[15:29:04] <roycroft> you're correct, that would not be that big a deal
[15:29:06] <gregcnc> how long from switching on until the breaker trips?
[15:29:07] <roycroft> it would take me 20 minutes
[15:29:15] <roycroft> well
[15:29:19] <roycroft> i'm *never* around when it happens
[15:29:20] <CaptHindsight> https://www.ebay.com
[15:29:23] <roycroft> but i assume almost immediately
[15:29:24] <jymmmm> roycroft: and give you room to use your clamp meter too
[15:29:31] <roycroft> yes
[15:29:50] <roycroft> sometimes the compressor will go for days on end without tripping the breaker
[15:29:58] <roycroft> sometimes it will happen multiple times/day
[15:30:16] <gregcnc> what is panel supply voltage?
[15:30:23] <CaptHindsight> more often on warmer days by chance?
[15:30:32] <roycroft> it may be that when the pump stops while in a compression stroke it trips the next time it turns on
[15:30:39] <jymmmm> I just bought a Klein CL800, reads AC AND DC amperage up to 600A, and even measures caps, and temp
[15:30:43] <roycroft> the panel supply is 240vac
[15:30:51] <gregcnc> measured?
[15:30:54] <roycroft> and i'm feeding 60a to the panel
[15:30:56] <roycroft> a long time ago
[15:30:58] <CaptHindsight> is the voltage lower on those days?
[15:31:00] <roycroft> when i first installed it
[15:31:16] <roycroft> it seems to happen at night mostly
[15:31:28] <roycroft> and during the summer that would tend not to be a low voltage time
[15:31:32] <roycroft> but i've not measured
[15:31:36] <jymmmm> roycroft: around 6 to 8 pm?
[15:31:39] <roycroft> no
[15:31:42] <roycroft> like the middle of the night
[15:32:00] <roycroft> i usually leave the compressor on all the time except when i'm doing maintenance on it
[15:32:13] <roycroft> i don't turn it off and drain it every day
[15:32:20] <roycroft> i drain it every couple weeks or so
[15:32:24] <roycroft> and don't get much water
[15:32:42] <roycroft> it's out of the way enough that it's a hassle to turn it on and off all the time, so i just leave it on
[15:33:17] <roycroft> i should put a mark on the pump sheeves so i can note the location when it's tripped
[15:33:31] <roycroft> if the mark is in the same location every time that would indicate that it's stopped on a compression stroke
[15:33:59] <roycroft> and that might indicate that, even though i've swapped the unloader in the past, it might be a problem with the unloader
[15:34:07] <CaptHindsight> I'd swap 20A breakers and see if it goes away
[15:34:23] <roycroft> i might have a spare 20a breaker
[15:34:30] <roycroft> if so that's the easiest thing to do
[15:34:36] <roycroft> easy and free
[15:34:49] <roycroft> swapping the wires for 10ga if they're currently 12ga is almost as easy
[15:34:53] <roycroft> and is still free
[15:35:02] <roycroft> as in no out-of-pocket, since i have wire in stock
[15:35:41] <CaptHindsight> sounds like a plan
[15:35:41] <roycroft> i do hear the unloader vent whenever the pump stops
[15:35:55] <roycroft> so that's another reason i don't suspect it
[15:36:21] <roycroft> but putting a mark on the sheave is very cheap and very easy
[15:37:18] <roycroft> i've never once had it trip immediately after resetting it
[15:38:00] <jymmmm> roycroft: FWIW.... I just replaced the fan motor on my HVAC unit. It's rated at 1.8A, but I JUST measured the inrush current 2 minutes ago at it was, 4.76A, 2.5x greater than it's rating.

[15:43:43] <CaptHindsight> https://www.mikeholt.com
[15:44:37] <jymmmm> CaptHindsight: By that first link, a 16A motor should be on a 24A circuit (125%)
[15:45:11] <gregcnc> ? 16x1.25=20
[15:46:58] <jymmmm> gregcnc: oh, duh, my bad =)
[15:47:10] <jymmmm> fat fingers =)
[15:49:41] <CaptHindsight> yes 20A is the MINIMUM overcurrent protection device required
[15:50:58] <Tom_L> jymmmm, you just wanted to play with your new meter
[15:51:26] <jymmmm> Tom_L: Um, maybeeeeee
[15:51:44] <jymmmm> Tom_L: I already OL starting the car =)
[15:52:20] <jymmmm> Tom_L: I was thinking about getting the CL900, 1200A, but then you lose other features
[15:52:23] <roycroft> i've considered getting a bigger subpanel and putting the compressor on its own 30a circuit, while keeping the remote belt grinder on a 20a circuit
[15:52:32] <roycroft> but that would cost a couple hundred dollars or so
[15:52:47] <roycroft> i still may go that route
[15:52:58] <roycroft> it would probably be less expensive than that soft starter
[15:53:06] <roycroft> although it would be more work
[15:53:27] <roycroft> especially if i could use my existing breakers it would be less expensive
[15:53:47] <CaptHindsight> wait 5hp motor?
[15:54:45] <jymmmm> 7ft of 10ga seems to be the cheapest first solution attempt, then a new breaker, then maybe soft start, or new sub panel, Lastly, get 200 neighborhood squirrels, and an espress machine
[15:54:45] <Tom_L> i wired 10ga to mine, never had any issues

[15:56:38] <jymmmm> Like 20 Mule Team, but 2000 Squirrel team
[15:57:23] <CaptHindsight> 5hp 230V should be 28A
[15:57:45] <jymmmm> the espresso machine is to keep them pumped up
[15:57:52] <CaptHindsight> for single phase motor ^^
[15:58:02] <roycroft> i think your maths are off
[15:58:10] <CaptHindsight> for 3 phase 230V 5hp motor 15.2A
[15:58:13] <roycroft> 1hp = ~750w
[15:58:20] <CaptHindsight> https://www.engineeringtoolbox.com
[15:58:47] <jymmmm> This 1/4HP 1ph 220V motor I just replaced is 1.8A
[15:59:09] <roycroft> this motor is a us-made leeson
[15:59:12] <Tom_L> uphill or down?
[15:59:15] <roycroft> it does not use foreign watts
[15:59:20] <roycroft> it uses real, american watts
[15:59:32] <CaptHindsight> https://www.jcalc.net
[16:00:13] <roycroft> > 750*5
[16:00:14] <roycroft> => 3750
[16:00:17] <roycroft> so yes, 3.75kw
[16:00:28] <roycroft> similar to the 3.5kw on that website
[16:00:34] <roycroft> > 3750.0/240
[16:00:34] <roycroft> => 15.625
[16:00:40] <CaptHindsight> plus efficiency and power factor
[16:00:45] <roycroft> at 240vac thats 15 1/2a
[16:01:01] <roycroft> correct
[16:01:12] <roycroft> but for a decent us-made motor that's not 50% loss
[16:01:24] <CaptHindsight> go by the name plate
[16:01:35] <roycroft> i'd have to go look
[16:02:02] <roycroft> but i believe that the current draw listed on the nameplate is total current, including efficiencey and power factor loss
[16:02:11] <roycroft> so it's really not going to deliver 5 full hp
[16:02:16] <roycroft> it's going to draw 5hp worth of power
[16:02:35] <roycroft> and deliver 5hp - efficiency and power factor loss
[16:02:48] <CaptHindsight> 5hp 230V should be 28A Full-Load Current
[16:03:17] <roycroft> i thank that the underwriters' laboratory would have issues with a device that states that it draws 16a at full load but really draws almost 2x as much

[16:08:07] <roycroft> hmm, it actually doesn't say what the rated current draw is on the motor itself
[16:08:21] <roycroft> power factor is 95 and efficiency is 82.5%
[16:08:49] <gregcnc> says 5HP though?
[16:08:53] <roycroft> yes
[16:09:02] <roycroft> and it is continuous duty
[16:09:09] <roycroft> i forgot that i bought a continuous duty motor
[16:09:31] <roycroft> this compressor was originally a 5hp husky brand that i bought at home depot
[16:09:47] <roycroft> after the chinese pump blew up i bought a really nice us-mae pump
[16:09:55] <roycroft> after the chinese motor died i bought a good us-made motor
[16:09:57] <gregcnc> I'll go with t he breaker is too small, for $200
[16:10:06] <roycroft> both the pump and the motor died within the first couple years
[16:10:20] <roycroft> their replacements have been working for close to 20 years
[16:10:51] <roycroft> the 60 gallon tank that is the only part of the compressor that is still original (although i've painted it) is in great shape
[16:11:29] <roycroft> actually, after the chinese pump blew up i replaced it with another chinese pump from harbor freight
[16:11:52] <roycroft> then when that one blew up i bought a real one, and paid way more than what i originally paid for the whole unit
[16:12:14] <roycroft> to upgrade the breaker means a new subpanel
[16:12:21] <roycroft> doable but not my first choice

[16:37:17] <miss0r2> Installation of solar panels complete: https://imgur.com
[16:38:02] <gregcnc> what kind of panels?
[16:38:17] <miss0r2> Some flexible monocrystal ones
[16:38:21] <miss0r2> 120watt each
[16:38:49] <gregcnc> glued?
[16:39:24] <gregcnc> just curious if that installtion is going to last
[16:39:26] <miss0r2> will be. At the moment they are just held in place with 6 4mm screws each. But those screws are just ment to "catch" them if the glue fails
[16:39:36] <miss0r2> I need more room above the car before I glue it up :D
[16:40:13] <miss0r2> They need to be glued. Otherwise they will vibrate to peices with the wind blowing across right fast in a hurry
[16:41:24] <jymmmm> miss0r2: silicone, then you can use a plastic scraper to remove them
[16:41:27] <gregcnc> right
[16:41:54] <miss0r2> Makes sense. But silicone doesn't hold as well as proper elastic glue.
[16:42:09] <jymmmm> miss0r2: I have never seen silicone fail
[16:42:12] <miss0r2> And it goes to reason I would only remove them if they fail, and would not be too worried about damaging them
[16:42:23] <miss0r2> hmm
[16:42:36] <roycroft> i hope you never plan on painting anywhere near those panels if you use silicone adhesives
[16:42:44] <CaptHindsight> miss0r2: the tent will also block the light :p
[16:42:50] <miss0r2> I wonder if I should get some proper "acid free" silicone to make sure it does not damage the panels
[16:43:09] <miss0r2> CaptHindsight: Naturaly I will 'try' to park the car facing south
[16:43:10] <jymmmm> miss0r2: aquarium grade silicne?
[16:43:26] <jymmmm> dont forget to park on an angle too =)
[16:43:30] <CaptHindsight> they make silicones for solar cells
[16:43:33] <miss0r2> Jymmm: I'm not sure what particular ones are not acid..
[16:43:44] <miss0r2> yeah yeah yeah... :D
[16:43:52] <roycroft> acute or obtuse angle?
[16:43:53] <CaptHindsight> I have some here
[16:44:00] <jymmmm> miss0r2: I think anything made for an aquarium with be safe once cured
[16:44:07] <jymmmm> but that is just a guess
[16:44:40] <miss0r2> Jymmm: hmmm. Perhaps some of that silicone CaptHindsight speaks off, made particular for solar panels. It would make sense that should not harm it
[16:44:51] <CaptHindsight> it's made to encapsulate the cells so it passes 99% of the light through it
[16:45:16] <miss0r2> I already have double the solar capacity I *should* need, so i think a bit of shade once in a while will be okay - even if the angles are less than desireable
[16:45:18] <jymmmm> We used to use dry cleaning solvent to remove silicone
[16:45:24] <CaptHindsight> the name is like Silguard
[16:45:39] <miss0r2> CaptHindsight: well, that just sounds like throwing money away for this particular use
[16:45:50] <CaptHindsight> https://www.dow.com
[16:46:30] <CaptHindsight> look through the sdelector, they have acid free neutral ph stuff
[16:46:54] <miss0r2> CaptHindsight: I think I will just call the local kemical supply and ask them for something
[16:47:05] <miss0r2> Seems a bit more straight forward.
[16:47:05] <CaptHindsight> yeah, it will likely be similar
[16:47:10] <miss0r2> yeah

[16:47:54] <miss0r2> Anyway. My birthday tomorrow, and I promised my kids that I would make pancakes for breakfast... and it is not 22:47 (me planning to make the "dough" tonight). So I better call it a night
[16:48:08] <miss0r2> not=now
[16:48:23] <jymmmm> miss0r2: Wait, it's YOUR bday, and YOU are making ancakes, not the kids?
[16:48:27] <miss0r2> See you around. I will be back to pick your brain about what breakers to get, Jymmm.
[16:48:30] <CaptHindsight> happy B-day
[16:48:31] <miss0r2> yeah
[16:48:36] <miss0r2> kids 1.5 and 4
[16:48:45] <jymmmm> miss0r2: lol, HAPPY BRTHDAY!!!!
[16:48:47] <miss0r2> I'd rather do it myself :D
[16:49:00] <jymmmm> miss0r2: Oh get the 4yo, on video doing it, that should be funny
[16:49:21] <miss0r2> knowing I will have less of a mess to deal with afterwards doing it myself, I think that will be the solution
[16:49:31] <jymmmm> garden hose?
[16:49:33] <jymmmm> lol

[17:04:33] <XXCoder> nah getting ready to go to work now

[17:08:51] <XXCoder> looks like no though they removed "can unmask when alone"
[17:09:00] <XXCoder> so everyone must constantly wear masks
[17:09:20] <XXCoder> im definitely serlizing everuthing before i begin work
[17:09:34] <XXCoder> and touch nothing unrelated to my work
[17:10:39] <XXCoder> well laters
[17:11:47] <Tom_L> they had a mask rule at my kid's work for quite a while then lifted it
[17:12:05] <Tom_L> then someone got sick and now it's back to masks full time
[17:13:08] <roycroft> a new order went into effect in oregon today
[17:13:20] <roycroft> masks are now required outdoors where social distancing is not possible

[17:14:37] <roycroft> the sooner people get used to masking and the sooner we get a government that actually cares about testing and tracing the sooner we'll be able to open the economy up fully
[17:14:53] <roycroft> it's ironic that the people who want most to open things up are the very ones who are preventing it
[17:22:07] <roycroft> what is really sad is that young teachers all over the country are writing wills this month
[17:22:20] <roycroft> older teachers too, them that don't already have one
[17:22:53] <roycroft> but if you're a teacher in your 20s you should not have to worry about writing a will before you go back to work
[17:23:27] <Tom_L> you're more apt to be texting on your way to work at that age
[17:23:33] <Tom_L> not much difference in the end really
[17:25:39] <roycroft> i should hope not many are texting on their way to work
[17:25:49] <roycroft> but if they are, and something happens, it's their own doing
[17:26:08] <Tom_L> and anyone else that happens in their way
[17:26:14] <roycroft> being forced to work in unsafe conditions to stroke the ego of the president is an entirely different matter
[17:26:36] <Tom_L> taking the political route here ehh?
[17:26:47] * Tom_L is done
[17:26:59] <roycroft> there is no legitimate argument against acting safely except a political one
[17:27:19] <roycroft> and that's not a legitimate argument
[17:27:26] <roycroft> it's the only argument against being safe
[17:27:33] <roycroft> teachers want to go back to work
[17:27:48] <roycroft> they do not want to be ordered to pack their classrooms and not have anyone wear masks
[17:29:21] <roycroft> but i'll accept that any political element is not wanted as part of a discussion, and so will not press on with the topic
[17:29:34] * roycroft will just remain sad

[18:51:32] <transhumanist1> Hi! sorry for the repeat, but I have spoken to a few people in this group. I thought one had told me the reason the Z axis is always so short compaired to the X and Y axis on CNC machines. I thought it had to do with flexure, is this correct?

[18:57:17] <transhumanist1> Hi! I thought the reason for the limited z axis height in cheap CNC machines is mainly due to flexure increases with increased height. where for some reason this donesnt affect x and y axis. Is this correct? thanks
[19:04:12] <perry_j1987> the x/y is always milling over the supported area
[19:04:28] <perry_j1987> the z on the otherhand is more flexible cause of its length

[19:56:19] -!- dan2wik has quit [Ping timeout: 244 seconds]
[19:57:07] <andypugh> But I think that the logic with a mill is that you would always arrange the workpiece, where you had a choice, so that the Z dimension is smallest asa that goves the tool the best access to more of the work and at a lower reach.
[19:57:50] <gregcnc> he's talking about chinaco routers. it's because they are routers
[19:57:52] <andypugh> I am sure that there have been some mills made that are a perfect cube. And I think that on my mill the Y axis is actually the shortest.
