#linuxcnc Calendar

01:26 AM randy: morning
02:10 AM Deejay: moin
04:04 AM Tom_L: morning
05:24 AM JT-Cave: mornin
05:26 AM XXCoder: heys
05:52 AM -!- #linuxcnc mode set to +v by ChanServ
11:42 AM Tom_L: everybody must be hard at work today
11:42 AM JT-Cave: must be
11:43 AM JT-Cave: I did plant a tomato plant sideways this morning and sift 4 gallons of blast media
11:43 AM Tom_L: you finish your wood rack?
11:44 AM JT-Cave: firewood rack?
11:44 AM Tom_L: yeah
11:44 AM JT-Cave: no, I stopped working on it till the price of lumber gets back to normal
11:44 AM Tom_L: wasn't sure if the price of lumber halted that
11:45 AM JT-Cave: I only have the roof left to build but I said screw you I'm not buying a single stick of wood
11:45 AM JT-Cave: I tossed some metal roofing up on top, it does pretty good at keeping the firewood dry
11:45 AM Tom_L: retailers will milk it as long as they can too
11:46 AM JT-Cave: let them milk no sales as long as they like
11:48 AM JT-Cave: HD is still at $46 a sheet for 7/16" osb
11:49 AM Tom_L: what was it before the 'pandemic'
11:49 AM JT-Cave: $8
11:49 AM roycroft: osb is probably the most overpriced building material right now
11:49 AM Tom_L: last time i got any was around $7
11:49 AM roycroft: mdf coming in a close second
11:50 AM roycroft: the claim is that there's a global resin shortage due to the pandemic
11:50 AM Tom_L: pretty soon they'll haul large machines on site and 3d print homes
11:51 AM roycroft: someone in the netherlands has already 3d printed homes
11:51 AM Tom_L: concrete
11:51 AM roycroft: i think it was done lego style though
11:51 AM Tom_L: they do that here with foam forms
11:52 AM * roycroft is dealing with ups today
11:52 AM roycroft: they just send me a bill for $32.45
11:52 AM Rab: When I checked a few months ago, cabinet-grade plywood was 1/3 less than OSB. Seems like a no-brainer to me, unless it would run afoul of code requirements! (Plywood's since gone up.)
11:52 AM roycroft: for a shipment on my account that is closed, and that their fraud departent confirmed was closed last month due to fraudulent use of it
11:53 AM roycroft: their billing folks are demanding that i pay
11:53 AM cloudevil: Wickes for 11mm OSB wants 29 quid, or about $41 https://www.wickes.co.uk/Wickes-General-Purpose-Oriented-Standard-Board-3-OSB-3---11-x-1220-x-2440mm/p/170914
11:53 AM roycroft: i just picked up a sheet of shop grade fire resistant 3/4" osb for $24
11:53 AM roycroft: it's indistinguishable from the standard grade, which is currently $70
11:54 AM roycroft: that should cost about £6, i should think, cloudevil
11:55 AM roycroft: and sorry, i meant i picked up mdf, not osb
11:55 AM roycroft: we were talking about osb, and i had it on the brain
12:01 PM * JT-Shop pre-heats the soldering iron
12:02 PM Tom_L: getting awfully close to lunch min to start a project...
12:05 PM JT-Shop: lunch minute passed almost an hour ago
12:09 PM * JT-Shop waits for the iron to cool off to fit a larger tip
12:10 PM cloudevil: Waffle-iron tip.
12:10 PM djdelorie: silicone fingers
12:15 PM Tom_L: https://www.hisco.com/UserFiles/Images/Products/weller-12200_sp175_DV_WebXL.jpg
12:15 PM Tom_L: not for smt
12:17 PM djdelorie: well, if you're surface mounting 100 amp diodes...
12:18 PM JT-Shop: I got the wire off but put it right back on as too much copper is missing at the injury so a splice there
12:18 PM JT-Shop: that's a bad ass solder iron
12:25 PM roycroft: my stained glass soldering iron is pretty big
12:26 PM roycroft: the ones that roofers use for soldering copper roofing seams are huge, though
12:32 PM Connor: Hello
02:09 PM JT-Shop: X servo sounds much nicer now... just need another drive now
02:10 PM skunkworks: JT-Shop: what ended up being the problem?
02:12 PM Joe_Hildreth: The Mesa 5i25/6i25 running the PROB_RFX2 configuration ... says it will support most parallel breakout boards. So I could use this config with the BOB that I was using with the PP setup, correct? Just setup the pinouts in pnconf accordingly?
02:13 PM JT-Shop: did you flash the 5i25?
02:15 PM JT-Shop: skunkworks, one of the armature wires was rubbing on the encoder coupling and finally shorted out enough to make a pop sound, all repaired except the drive
02:15 PM Joe_Hildreth: Not yet, just making sure I understand it correctly.
02:16 PM Joe_Hildreth: JT, the reason why I ask is I would like to cover that solution for people who used a PP and a BOB for their machine as a way of getting away from the PP but still be able to use the existing BOB and other hartdware.
02:16 PM JT-Shop: sounds about right to me
02:17 PM JT-Shop: I need to make a front end for mesaflash that is easy to use
02:17 PM Joe_Hildreth: I think it the next natural progression for the small home hobby guy/gal
02:17 PM JT-Shop: my configuration tools for the 7i96, 7i95, 7i92 and 7i76e all flash firmware
02:18 PM Joe_Hildreth: Looking at LCNC using pnconf, looks like you select the 5i25 and the prob_rfx2 from the list and you can assign the pins from there.
02:21 PM JT-Shop: pncconf confuses me too much to try and use it
02:35 PM * Tom_L thinks JT-Shop will be an expert on servo repair soon
02:42 PM * JT-Shop hopes it's so long that he forgets how to take one apart
03:29 PM * Vq considers sending JT his broken BP servos.
03:32 PM JT-Shop: are they Anilam servos?
03:33 PM Vq: They are all Siemens.
03:33 PM * JT-Shop forgets what is in the CHNC and 308
03:34 PM Vq: It's the original servos from an APC 630.
03:35 PM Vq: I think only the high-voltage unit and/or the spindle servo is actually broken.
03:36 PM Vq: Got some extras of those expensive semi-conductor fuses as well.
03:57 PM JT-Shop: I wish I could convert the 308 to LinuxCNC and get rid of the 386 motherboard
03:59 PM Joe_Hildreth: That goes back a few days. I think the first compute I built was a 386DX40.
04:01 PM JT-Shop: my first pc was an 8086...
04:01 PM JT-Shop: I was so proud when I got my 80286
04:02 PM Joe_Hildreth: My first was a PET4, then a few oteh CBM machines before moving into a 286.
04:02 PM JT-Shop: never even heard of them
04:02 PM Joe_Hildreth: They were the precursors to the Commodore 64/128 and VIC 20 machines
04:03 PM JT-Shop: ah, and now I remember having a commodore
04:03 PM Joe_Hildreth: My buddy had a Heath kit H8. Now that was a cool box!
04:03 PM JT-Shop: I built a heath kit rc set
04:03 PM Joe_Hildreth: I miss that stuff.
04:05 PM Joe_Hildreth: I built a Heath kit FM transmitter. That thing was awesome. Well, till the neighbors complained. haha
04:06 PM Tom_L: i had that heathkit pc trainer thing
04:07 PM Tom_L: commodore portable
04:07 PM perry_j1987: hows it going
04:07 PM roycroft: i built a lot of heathkit stuff when i was a kid
04:07 PM roycroft: as well as a bunch of archer kits from allied radio
04:07 PM roycroft: later allied radio shack
04:07 PM roycroft: later radio shack
04:08 PM roycroft: later defunct
04:08 PM Tom_L: i never had a CPM os pc though
04:09 PM Tom_L: 8088 was my first
04:09 PM roycroft: i never owned a machine that ran cpm, but i sure programmed on a lot of them back in the day
04:09 PM * Vq is a Z80 kid
04:10 PM roycroft: i used to have a rack-mount z8000 machine that ran pickos
04:10 PM roycroft: it had a 9 track tape drive and a 100MB 14" hard drive
04:10 PM Vq: Grew up with the cheap Sinclairs
04:11 PM roycroft: i still have the platters from that hard drive
04:11 PM Tom_L: roycroft, i've seen those platters
04:17 PM JT-Shop: shipping label for the drive has been created... lets see if this guy takes 4 days to wander down to the usps office
04:18 PM JT-Shop: Tom_L, in case you missed the replacement servo works perfect now, I tested with the Y drive
04:20 PM JT-Shop: I think I'll finish sifting the blasting media in the morning when it's cooler
04:21 PM JT-Shop: XXCoder, you awake?
04:23 PM Jym: Hello
04:23 PM JT-Shop: yo
04:24 PM Tom_L: JT-Shop, did it get the driver?
04:25 PM Tom_L: must have...
04:26 PM Tom_L: the servo must have had a problem all along
04:31 PM JT-Shop: I think the drive is borked because I put the Y drive in the X slot and X homed nice and smooth
04:32 PM JT-Shop: aye the shorted armature wire was causing the problem... too bad I didn't find out before toasting the drive
04:40 PM XXCoder: JT-Shop: hey whats up
04:42 PM JT-Shop: sifting the blasting media in front of a box fan did real well to blow the fines out and let the good media drop into a pan
04:43 PM XXCoder: nice
04:48 PM Jym: Hey JT-Shop
04:49 PM Tom_L: Jym, do your 'm's grow the longer you're here?
04:50 PM Jym: Tom_L: depending on the irc client =)
04:50 PM Jym: ...and multiple connections
04:56 PM Tom_L: JT-Shop, did you end up going new or used?
04:57 PM JT-Shop: drive?
04:58 PM Tom_L: yeah
04:59 PM JT-Shop: no such thing as new ones, just gotta find one on flea bay
05:05 PM Tom_L: :/
05:06 PM JT-Shop: that looks like someone smoking a cigar...
05:06 PM Tom_L: popeye
05:07 PM JT-Shop: lol
05:08 PM * JT-Shop goes to see if the wife is tired of chicken watching
05:38 PM * JT-Shop wonders what he can use to make a 0.025" wide slot in a piece of 1/4" aluminum
05:38 PM perry_j1987: how long
05:39 PM skunkworks: slitting saw...
05:39 PM perry_j1987: im guessing its not on the side of the 1/4" alum
05:40 PM JT-Shop: smallest slitting saw is 0.048" it might do
05:40 PM JT-Shop: maybe 1" long
05:41 PM perry_j1987: whats the slot for that small
05:41 PM Tom_L: i've got a couple thin ones if you wanna get em
05:41 PM JT-Shop: just need to center a utility knife blade over wire to strip it... just did a mock up test and stripped 50' of fine stranded ground wire pretty easy
05:41 PM perry_j1987: oh just 3d print a guide for something like that :)
05:42 PM JT-Shop: I'll try the 0.048" blade
05:42 PM JT-Shop: none of my printers are working
05:42 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/Slitting_saw2.jpg
05:42 PM Tom_L: i don't remember how thick that thin one is
05:42 PM perry_j1987: whats wrong with the printers
05:43 PM JT-Shop: I have a stack of 0.062" and that tin of 0.048" blades
05:43 PM JT-Shop: can't get the print to start without lifting or something like that... been a while since I tried
05:43 PM perry_j1987: aquanet purple can
05:44 PM JT-Shop: I have white rain
05:44 PM perry_j1987: but if you want to make it and you cant slit it, you could mill 2 halves and screw them together forming the slit too
05:45 PM JT-Shop: aye, looking for simple to test my idea with
05:45 PM perry_j1987: that'd let you make an angled chanel for the blade to be held in too
05:45 PM perry_j1987: but you prob dont even need a slit
05:45 PM perry_j1987: you could just take two pieces of your alum and bolt them together forming a clamp for the blade
05:45 PM JT-Shop: I'm holding the utility knife in my hand just need to keep it in the center of the wire
05:46 PM JT-Shop: that way I can control the pressure
05:46 PM perry_j1987: aye
05:48 PM JT-Shop: hmm I could clamp the blade and have the holder floating then use my hand for pressure...
05:49 PM JT-Shop: that way the blade stays in the same spot
05:51 PM perry_j1987: im imagining two strips bolted together and then you use a ball endmill to run a channel down the joint
05:51 PM perry_j1987: open one end slide blade tip into the notched spot and make it long enough you can use the clamp as your handle of your new tool
05:52 PM perry_j1987: tool would ride the wire and depending on your angle that you hold it would dig the blade in more or less into the wire
05:52 PM perry_j1987: or you could have only so much poking down that you could hold the whole thing flat to a table
05:52 PM perry_j1987: and pull wire through it
05:53 PM perry_j1987: or clamp it to workbench and pull wire though it
05:53 PM JT-Shop: kinda sorta starting to visualize your idea I think...
05:54 PM perry_j1987: ya so two pieces of your alum bolted together to form a clamp then pop that in your mill vise and run a small ballendmill down the length of the joint to form your wire channel
05:55 PM JT-Shop: the wire channel needs to be adjustable
05:55 PM perry_j1987: pop a blade in there and clamp to your workbench then you can pull wire through it all day long to your hearts content heh
05:55 PM perry_j1987: what range
05:55 PM JT-Shop: 1/16" to 1/2"
05:55 PM perry_j1987: ah ok
05:56 PM Tom_L: V cut the slot
05:56 PM JT-Shop: I don't think I have anything bigger than 1/2" OD that needs scrapped
05:56 PM perry_j1987: ya
05:56 PM perry_j1987: V cut would be much better
05:56 PM perry_j1987: could alwyas just barrel burn the wire haha
05:56 PM Tom_L: have the blade point at the end of it
05:56 PM JT-Shop: I've watched videos on putube with a v roller and the wire is all over the place
05:57 PM JT-Shop: tried burning and it just made a mess of crap
05:57 PM Tom_L: heh
05:57 PM perry_j1987: a V slot is fully adjustable from 1/16 to 1/2
05:57 PM Tom_L: did you see the one with the treadmill roller?
05:57 PM JT-Shop: the test I did was with a piece of 3/8 c clamped next to my vise to form a channel
05:57 PM JT-Shop: worked well
05:58 PM Tom_L: think bigger than 1/2". the wire isn't going to cooperate
05:58 PM JT-Shop: I saw some with smooth rollers and that only works with solid core wire
05:58 PM Tom_L: ok
05:58 PM perry_j1987: i gotta pack up - in coffee shop now thats closing heh
05:58 PM perry_j1987: cya guys later
05:59 PM JT-Shop: most of the wire I have is stranded wire from hospital equipment
05:59 PM JT-Shop: coffee at this hour... time for vino
05:59 PM Tom_L: any multi bundled?
05:59 PM JT-Shop: some so cord but not much
06:00 PM Tom_L: set up a V pulley ahead of your cutter to help guide the wire
06:00 PM JT-Shop: got a few hundred feet of 3 wire twisted but no coat for deep well
06:00 PM Kevin`_ is now known as Kevin`
06:01 PM JT-Shop: I think I've been scrapping this pile for years lol
06:01 PM Tom_L: or a funnel of some kind
06:02 PM JT-Shop: if that guy gets the drive to the po tomorrow I should have it in 3 days
06:02 PM * JT-Shop wanders into the house to call it a day
06:15 PM roycroft: my fuses have shipped, so i should have them by week's end
06:15 PM CaptHindsight[m]: https://twitter.com/i/status/1404466187208065034 toasty fire minutes away
06:15 PM * roycroft is waiting for glue and paint to dry again
06:16 PM roycroft: i'm getting really near the point of main assembly of my stand, which will free up a lot of space so i can start making drawers
06:16 PM roycroft: i've been somewhat following that, capthingsight
06:16 PM roycroft: it's a pretty bad situation
06:18 PM CaptHindsight[m]: massive grease fire, lubricating not chicken fat
06:18 PM roycroft: yeah
06:18 PM roycroft: the perfect fuel for big, billowing black smoke and lots of heat
07:31 PM roycroft: wow
07:32 PM roycroft: it's kind of hard to believe, but it looks like this will likely be our last week of mask wearing in oregon
07:32 PM roycroft: our governor will lift the mask mandate when we hit 70% vaccinated, and she projects that will be by the 21st of this month
07:32 PM XXCoder: nice
07:32 PM roycroft: yeah
07:33 PM XXCoder: wonder what is wa stte is at
07:33 PM roycroft: i haven't heard
07:33 PM roycroft: but i think you're not far behind oregon in statewide vaccinations
07:33 PM roycroft: i don't know what governor inslee's plans are, though
07:34 PM roycroft: my county is already permanently in the lowest risk category, which means most things are open at full or near full capacity
07:34 PM roycroft: the olympic track trials are officially on, with 1/2 capacity at the stadium
07:35 PM roycroft: it will be so nice when this pandemic is behind us, or mostly behind us
07:43 PM roycroft: now if we could just erect a border wall with idaho, which has the lowest vaccination rate in the country outside the deep south
07:44 PM XXCoder: yeah idaho wanted to take over east parts of wa and oregon
07:47 PM roycroft: yes, a bunch of counties in southern and eastern oregon have voted to join idaho
07:47 PM roycroft: that's not going to happen though
07:47 PM roycroft: and if they did, they would starve
07:47 PM roycroft: because it's all the poor counties that are subsidised by the rest of the state that want to leave, and idaho doesn't have the money to support them
07:47 PM XXCoder: indeed
07:48 PM XXCoder: would benefit wa and or lol
07:48 PM XXCoder: less welfare, and more liberal chances than already is
07:48 PM roycroft: anyway, much of that will go away as we move beyond the pandemic restrictions
07:49 PM XXCoder: id say so yeah
07:49 PM roycroft: but for those counties to become part of idaho, the oregon state legislature would have to agree, the idaho state legislature would have to agree, the us congress would have to agree, and the president would have to agree
07:49 PM roycroft: so it's not going to happen
07:49 PM cloudevil: Not the senate too?
07:49 PM cloudevil: Oh, nvm
07:49 PM roycroft: congress = house + senate
07:50 PM cloudevil: yes, I realised that just after typing.
07:53 PM roycroft: i figured that out
07:53 PM roycroft: but i had already pressed enter when i saw your nvm
07:53 PM XXCoder: timing isnt that fun lol
07:54 PM roycroft: it wasn't a major catastrophe
07:54 PM XXCoder: just almost world ending ;)
07:56 PM roycroft: i personally think it would be bad if those counties left the state
07:56 PM roycroft: it would just be more isolationism
07:57 PM XXCoder: true
07:57 PM roycroft: which would lead to more extremism
07:57 PM roycroft: and besides, progressives don't always get things right
07:57 PM roycroft: they need some checks on the stuff they do
07:58 PM roycroft: i like having multiple points of view
07:58 PM roycroft: a lot
07:58 PM roycroft: even if it seems sometimes that it slows down progress
07:58 PM XXCoder: i dont have true loyality to any party. ill call out to any politican that does wrong
08:00 PM XXCoder: and yeah many views is better
08:00 PM roycroft: same here, but it goes beyond that
08:00 PM roycroft: i want to engage with people who disagree with me
08:00 PM XXCoder: im just sick of "my ignorance is equal to your knowledge in general
08:00 PM roycroft: hear their views
08:00 PM roycroft: maybe i'm wrong
08:00 PM roycroft: maybe they can persuade me
08:00 PM roycroft: at the very least, i'll have a different perspective
08:01 PM roycroft: i've a group of friends with whom i worked at a freenet over 25 years go
08:01 PM roycroft: we all share similar political views, for the most part
08:01 PM roycroft: we have dinner almost every week, and have for all this time
08:02 PM roycroft: i've found myself somewhat of an outlier in the past few years, though
08:02 PM roycroft: the rest of the group are increasingly isolated from "conservatives", and have formed some unfair, very stereotypical views of them
08:02 PM roycroft: they think all "conservatives" think and act alike
08:02 PM roycroft: and i deal with folks on the right all the time
08:03 PM roycroft: i disagree with amost all of them on most things, but i don't lump them all into the same category and ascribe the same motives to all of them
08:03 PM XXCoder: indeed
08:04 PM roycroft: my friends have also bought into wokeness and all that safe space crap
08:04 PM roycroft: we have had some pretty major arguments about that
08:05 PM roycroft: they think that speech that can be "hurtful" (meaning that disputes my wokeness) should be suppressed
08:05 PM roycroft: some of that drives me up a wall
08:05 PM roycroft: truly hurtful speech is inappropriate, sure
08:06 PM roycroft: but challenging someone's ideas on an intellectual level, that is to be embraced
08:06 PM roycroft: anyway, we're way off topic here
08:06 PM XXCoder: indeed
08:06 PM roycroft: i'm just expounding a bit on why i think the more rural counties in our state should remain in our state
08:07 PM roycroft: it's good for them and it's good for the more urban counties
08:07 PM * roycroft head out to finish fixing dinner on that note
08:07 PM XXCoder: bah me hungry lol
09:44 PM * flyback slaps veegee around with fermented cashew fruit drink
11:09 PM veegee: flyback I don't get the reference :(
11:24 PM flyback: it's a indian drink
