04:58 AM JT-Cave: morning
05:17 AM Norfreakz[m]: hi, does anyone here know how the pin-numbering on MESA's HDR26 work? im trying to connect some swithces to them, and can seem to find any docuemtation of how the pinout is(as in what pin is where on the connector)... (full message at <https://libera.ems.host/_matrix/media/v3/download/libera.chat/2af6c1f52b7d3350c3311fa83074a76882c788f6>)
05:23 AM rmu: Norfreakz[m]: pins are numbered so a ribbon cable connected via IDC will have wire number = pin number
05:27 AM Norfreakz[m]: thank you!
05:29 AM rmu: "In absence of a pin 1 designation on the header, if a designation is missing from the header, the PCB may have a marking indicating orientation (historically, the solder pad around the hole of pin 1 of a THD header is often square rather than round).
05:29 AM rmu: For multi-row pin headers, the pin number is more complex, because knowing the location of pin 1 doesn't automatically ensure how the remaining pins are numbered. Typically for headers attached to ribbon cables, the pins are numbered so they go linearly across the cable. Because of the way the connector attaches to the cable, this means in a two-row header, pins in one row have odd numbers and
05:29 AM rmu: pins in the other row have even numbers.
05:29 AM rmu: "
07:19 AM JT-Cave: now where are my notes on reading the daughter card with mesaflash
08:52 AM travis_farmer[m]: 25F, with strong gusts of wind... maybe not a day for working outside... or at least not until later...
09:36 AM unterhaus_: below freezing now, supposed to get up to the 70s next week
10:25 AM roycroft: it's going to be nice here today - overcast, but high in the mid teens
11:31 AM sliptonicBradCol: Hey everyone. I'm looking for a coach. I need some help on a partial retrofit of my existing machine. I've done a lot of work on this machine over the years so I know my way around. Now I need to replace the old servodynamics amps which are acting up. It is going to take more time than I have available right now. So I'd like to pay someone to be my brain. Help me figure out what I need to order and then be available online
11:31 AM sliptonicBradCol: to help me work through the details of the conversion.
11:31 AM sliptonicBradCol: I'm willing to pay and no in-person or on-site time is required (though welcome if you're near mid-missouri).
11:33 AM JT-Cave: Lake of the Ozarks?
11:33 AM CaptHindsight[m]: sliptonic (Brad Collette): post your questions here or even better is start a forum thread
11:34 AM roycroft: how is the bandsaw project going, jt-cave?
11:35 AM JT-Cave: just came back from town with some electrical supplies
11:36 AM JT-Cave: what can I coat the brass engraved disk with to stop it from changing color after I polish it
11:37 AM travis_farmer[m]: sounds like a perfect job for me... except i am likely not the greatest person to get advice from... ;-)
11:37 AM roycroft: lacquer is the traditional coating for brass
11:37 AM JT-Cave: ok thanks
11:37 AM sliptonicBradCol: @JT-Cave Just south of Columbia
11:38 AM sliptonicBradCol: CaptainHindsight (@_discord_702231000050040894:jauriarts.org) roger. I'll post to the forum.
11:38 AM JT-Cave: we like going to Swiss and Hermann
11:39 AM sliptonicBradCol: You're over near festus aren't you?
11:39 AM JT-Cave: Poplar Bluff
11:49 AM CaptHindsight[m]: sliptonic (Brad Collette): chat is OK for simple questions like what is this pin for or what voltage is this interface, but for anything elaborate you're going to all sorts of half assed opinions here from random attention seekers unfortunately
11:49 AM CaptHindsight[m]: the forums allow for detailed posts and links
11:50 AM travis_farmer[m]: CaptHindsight: i feel like that was directed at me, the half-assed attention seeker...
11:50 AM sensille: oh, we are all good at that :P
12:02 PM Tom_L: <JT-Cave> now where are my notes on reading the daughter card... JT-Cave lemme know if you find them :)
12:03 PM JT-Shop: Peter just answered me on the forum
12:04 PM JT-Shop: https://forum.linuxcnc.org/27-driver-boards/48645-mesaflash-dbname-name
12:09 PM CaptHindsight[m]: travis_farmer: was not though
12:16 PM roguish[m]: JT-Shop: holy poop. JT, forum says you're an Administrator......cool.
12:17 PM Tom_L: JT-Shop, you probably can't get much result from a sserial can you?
12:51 PM JT-Shop: actually I'm a Super Administrator
12:52 PM JT-Shop: well sserial has no pins from the board the pins are discoverable and you can get the pin names with hal
12:55 PM roycroft: grr
12:56 PM roycroft: my router was supposed to be delivered on friday, and it made it to portland yesterday, but now it's "delayed"
12:56 PM roycroft: i wanted to spend some time with it this weekend
12:57 PM * JT-Shop is not having much luck polishing the brass without messing up the paint...
12:59 PM roycroft: how are you holding the badge?
01:00 PM JT-Shop: it's still in the top hat shape so in the lathe it's in a collet, a skim cut on the lathe left a bunch of chips in the paint
01:01 PM JT-Shop: the polisher pulls paint out... I've got it up to 600 by hand but don't have anything finer I don't think
01:01 PM roycroft: hmm
01:04 PM JT-Woodshop: I do have some micro fine honing compound...
01:05 PM JT-Woodshop: and wet stones to 8000
01:06 PM * JT-Woodshop goes to take a nap and dream up a solution...

03:15 PM JT-Shop: finally the starlink episode is over with, plugged the hole in the attic wall and took down my scaffolds
03:16 PM Tom_L: jinx'd for sure
03:16 PM Tom_L: just how shiney are you trying to get the brass?
03:17 PM Rab: JT-Shop, you had Starlink and you discontinued it?
03:17 PM Tom_L: his equipment failed him
03:17 PM JT-Shop: no, I had no service for a month or more due to fedex among others
03:18 PM JT-Shop: it wouldn't have been bad if the first replacement kit worked
03:20 PM Tom_L: JT-Shop, did you try polishing the brass then dripping paint in the lettering?
03:20 PM Tom_L: and let it dry
03:20 PM JT-Shop: no, I don't have a fine enough brush for that
03:20 PM JT-Shop: going to try my wet stones then srop it
03:21 PM unterhausen: the person that put the double doors in the basement used epoxy to install one of the jambs
03:22 PM unterhausen: Of course that's the one that needs to be shimmed in order to get rid of the gap between the doors
03:25 PM Rab: I use extra fine-tip paint pens to fill engraving, e.g.: https://www.amazon.com/dp/B005WXOKOW
03:25 PM Rab: Sometimes there's a little overage and I have to brush the metal surface again.
03:28 PM Rab: McMaster-Carr has the traditional crayons: https://www.mcmaster.com/products/crayons/paint-crayons-for-recessed-characters/
03:29 PM JT-Shop: interesting, not seen them before
03:31 PM JT-Shop: starlink just upgraded my service from best effort to residential
03:32 PM CloudEvil: What sorta speeds are you seeing?
03:32 PM JT-Shop: not looked yet
03:33 PM JT-Shop: 75 down 4 up
03:34 PM unterhausen: paint crayons seem useful, mil spec even
03:34 PM Rab: heh
03:35 PM Tom_L: JT-Shop, what were you getting before the upgrade?
03:35 PM Rab: I haven't tried the crayons. I heard about them through old timers reconditioning e.g. machine tool faceplates.
03:46 PM JT-Woodshop: depends on how busy the sat was
03:54 PM * JT[m] uploaded an image: (166KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/zTwkDHxlRSjRthNndmaQvXLf/20230330_155301.jpg >
03:55 PM XXCoder: weathered looking a bit
03:55 PM JT-Shop: I think it works for me :)
03:55 PM XXCoder: it looks nice
03:56 PM Tom_L: looks good to me
03:56 PM travis_farmer[m]: 👍️
03:56 PM Tom_L: we generally shot satin laquer on brass parts
03:58 PM JT-Shop: I'll put something on it after it's ready to mount
03:59 PM Rab: JT-Shop, I've also heard of using paste wax. Lacquer might be glossier for better 'shine'.
03:59 PM Rab: But beware, if your clear coat includes solvents then they can act on the paint in the lettering.
04:00 PM roycroft: paste wax won't prevent tarnishing as well as lacquer
04:00 PM Rab: Causing it to migrate into the coating and get a little fuzzy.
04:00 PM roycroft: almost any brass or brass-plated hardware you buy will be lacquer coated
04:01 PM Tom_L: yup
04:02 PM Tom_L: and if you put on 'dry' coats you won't lift the paint under it
04:14 PM roycroft: you could shoot a light coat of shellac over the badge first to seal the paint, polish that off, then shoot the lacquer over it
04:14 PM roycroft: or even not bother polishing the shellac off
04:14 PM roycroft: the lacquer will adhere to it just fine
04:15 PM roycroft: but i think you should be able to just shoot lacquer with no problems if you mist it on for the first couple coats
04:21 PM JT-Shop: ok
04:23 PM Tom_L: btw we used to use muriatic acid to 'polish' brass and coat it right after rinsing/drying
05:06 PM XXCoder: ohh https://www.youtube.com/watch?v=ItKH4Fh_j-o
05:06 PM XXCoder: interesting idea for machine
05:14 PM JT-Woodshop: doesn't look practical to me
05:16 PM Tom_L: not much more than a lathe with live tooling
05:21 PM JT-Woodshop: down in Broussard La the wedding and reception was at the fathers business, they made oil field parts and the shop was full of okuma lathes and vmcs
05:21 PM XXCoder: from what I see, I guess its designed for easier to use or something. its not captioned so i dont know whats being said
05:21 PM Tom_L: they are decent machines
05:21 PM Tom_L: steve had several okumas including a cadet lathe
05:22 PM Tom_L: i still have the gcode book for it
05:23 PM XXCoder: lol ok. well if he builds it and it works wondeful for him then great :)
05:23 PM XXCoder: wonder if he'd open source design, or patent and sell machines. likely latter
05:23 PM Tom_L: i see the hinge as one of the weak points
05:23 PM XXCoder: on the spindle? possibly
05:24 PM Tom_L: on the swing arm
05:26 PM XXCoder: what is swing arm?
05:26 PM Tom_L: the swivel in the front
05:26 PM XXCoder: what color is it on model
05:26 PM XXCoder: the oilve-greenish one?
05:27 PM Tom_L: i closed it
05:32 PM JT-Woodshop: I brought 50 1/4"-3/8" alum cord grips to my buddy at Revere today and told him if he runs out I have 50 more
05:32 PM JT-Woodshop: I'll never use them...
05:35 PM -!- #linuxcnc mode set to +v by ChanServ
05:47 PM XXCoder: Tom_L: its only hinge on machine so I think we are talking about same thing
05:53 PM JT-Woodshop: whew everything is plugged in... now to put a real blade on the bandsaw
05:53 PM Tom_L: JT-Woodshop, did you finish all those copier conversions?
05:56 PM JT-Woodshop: yup the copy lathes are done, still need to finish the double chucker
05:57 PM JT-Woodshop: started feeling sick with a sore throat sunday so I've been isolating until the creeping crud passes
05:57 PM Tom_L: she's got that now so i'll probably end up with it
05:57 PM JT-Woodshop: at least that is my excuse for taking this week off...
05:58 PM Tom_L: i didn't think you had to have an excuse after retirement :)
05:58 PM JT-Woodshop: wife has not had any symptoms so I think it's a good old fashion cold
05:59 PM Tom_L: those are still a thing? seems everything is being mislabelled now
05:59 PM JT-Woodshop: one thing for sure Jonas does not pressure me to get anything done which works out well for me
05:59 PM Tom_L: that's good
05:59 PM XXCoder: isolating at shop sounds fun
05:59 PM JT-Woodshop: rain tomorrow anyway
06:00 PM Tom_L: haven't checked the forecast but it's overcast here
06:00 PM JT-Woodshop: hmm this bandsaw blade has 5 loops when folded up... gotta figure out how to do that
06:00 PM Tom_L: wear gloves?
06:01 PM CloudEvil: Cut it and make it into a nice neat coil.
06:01 PM CloudEvil: Working out how to weld it properly may be faster than learning how to loop it properly.
06:04 PM JT-Woodshop: lol
06:04 PM JT-Woodshop: my buddy at revere is easy to work for too

06:05 PM Tom_L: :)
06:05 PM Tom_L: keep twisting
06:07 PM JT-Woodshop: a bit different but doable
06:07 PM JT-Woodshop: twist direction is important
06:20 PM JT-Woodshop: just need a 4" y fitting...
06:29 PM Tom_L: any trouble with static buildup in the tubes?
06:29 PM Tom_L: never ran a vacuum system so i dunno how that works
06:30 PM CloudEvil: It works fine until your shop explodes.
06:30 PM CloudEvil: (probably not usually)
06:31 PM CloudEvil: Dry plastic tubes with nonconductive dust being blown through them can make a surprising amount of voltage.
06:32 PM CloudEvil: All the issues I've had (minor) were cured by a run of copper wire taped onto the outside, and antistatic furniture polish.
06:33 PM JT-Woodshop: never had an issue...
06:33 PM Tom_L: never had that many tubes til now either ehh?
06:34 PM JT-Woodshop: when I made the diverter box a couple of years ago I had all the hoses
06:35 PM Tom_L: ok
06:35 PM JT-Woodshop: the pm1500 has two ports so the y is needed to catch them both
06:35 PM Tom_L: i saw the 2 outlets
06:36 PM JT-Woodshop: the cheap hose I used in the beginning would shock the crap out of you but the good stuff is grounded
06:36 PM Tom_L: that's good
06:36 PM JT-Woodshop: or conductive I should say
06:38 PM JT-Woodshop: hmm red barchetta one of my favorites
06:39 PM Tom_L: kid was a little pissed today, been thru 5 different forklift/crane safety classes and paid for an osha10 class and they still wanted him to spend the day 'training' again
06:39 PM JT-Woodshop: damn
06:39 PM Tom_L: and he's been doing all that for 6 months at the new job and all the sudden he needs to be trained on them
06:40 PM -!- #linuxcnc mode set to +v by ChanServ
06:40 PM JT-Woodshop: must be a new safety dude
06:40 PM Tom_L: company is based in Ca
06:40 PM JT-Woodshop: on submarine overhaul you had to be qualified for farting
06:40 PM Tom_L: i guess they want to make sure
06:41 PM Tom_L: you wouldn't wanna screw something up on a sub
06:41 PM JT-Woodshop: my attitude was always if you want to play instead of working it's ok with me
06:44 PM Tom_L: so tomorrow they get 6mo accident free pizza party. the foreman finally read his email after 3 months and saw that
06:44 PM JT-Woodshop: lol
06:45 PM JT-Woodshop: the foreman needs email training
06:45 PM Tom_L: he's an old school type
06:46 PM Tom_L: i don't think many like him there.. he more or less just gets in the way
06:46 PM * JT-Woodshop locks up and wanders inside
06:47 PM JT-Woodshop: a speed bump in production
06:47 PM Tom_L: he has realized the kid knows what he's doing though and for the most part leaves him alone
06:48 PM JT-Woodshop: that's cool
06:48 PM Tom_L: still way better than the last place
06:49 PM JT-Woodshop: that's good for him to have a better place to work
06:49 PM Tom_L: he's only 22 doing as well as me
06:49 PM Tom_L: but i'm slowing down some too
06:49 PM JT-Woodshop: that's pretty good for 22
06:50 PM JT-Woodshop: in my 20's I worked offshore in the gulf
06:50 PM Tom_L: back breaking young man's work
06:50 PM JT-Woodshop: yup
06:50 PM JT-Woodshop: but it paid twice what you could get on the beach
06:50 PM Tom_L: her dad was a crab fisherman a while
06:51 PM Tom_L: up in your neck of the woods
06:51 PM JT-Woodshop: fishing is a tough life
06:51 PM JT-Woodshop: time to call it a night

09:17 PM PlaidRabbit1814[: I'm doing my first big block of code on my cnc. I'm surfacing my spoilboard!
09:18 PM XXCoder: nice :D
09:18 PM roycroft: that's a good first thing to do
09:18 PM roycroft: i hope it turns out really flat
09:18 PM PlaidRabbit1814[: Yeah, it's mdf, but I've found it to be slightly lumpy...
09:19 PM XXCoder: yeah. if I recall right, its best to have shims under any rised areas before milling flat
09:19 PM roycroft: even if the spoil board is perfectly flat, you need to surface it to tram it to your spindle
09:19 PM XXCoder: so clamp dont push it and curve back up after release
09:19 PM PlaidRabbit1814[: I bolted the MDF down to the frame with ~50 bolts..
09:19 PM XXCoder: oh yes surface, rather than making part
09:20 PM roycroft: your router is not perfect
09:20 PM PlaidRabbit1814[: I can tell it's slightly out of tram. It's not enough for me to care. I'm mostly doing through holes.

09:21 PM XXCoder: makes sense, it really does depend on what jobs you running
09:21 PM roycroft: whoah
09:22 PM roycroft: $formerpresident has been indicted on over 30 charges
09:22 PM PlaidRabbit1814[: I'm working with sheet alum, and drilling holes in it, sometimes enlarging the holes, then doing edge cuts..
09:22 PM roycroft: i thought that was all on hold for a few weeks

09:23 PM roycroft: and gwyneth paltrow has been acquitted
09:23 PM XXCoder: interesting. newer bot version does s/(oldword)/(newword) now. before it would do whole thing again
09:23 PM roycroft: well
09:23 PM roycroft: it wasn't criminal in her case, it was civil
09:23 PM roycroft: so she has been found not liable
09:25 PM PlaidRabbit1814[: But I have spots where my router is taking off nearly 0, and spots where it's taking off ~1/16".

09:34 PM Rab: PlaidRabbit1814[, considered a vacuum table? Unless you're holding down the sheet with carpet tape or spray adhesive or something..
09:35 PM PlaidRabbit1814[: Yeah. Planning on using adhesive. Though with a wood spoilboard, I can actually just put wood screws through the sheet metal.
09:36 PM roycroft: with your application, holding down the material seems more important than having the surface absolutely flat
09:37 PM PlaidRabbit1814[: It needs to be "close enough", or it doesn't cut/ramp in/ramp out correctly.
09:38 PM PlaidRabbit1814[: Though I hadn't considered spray adhesive. Suggestions?
09:38 PM roycroft: a vacuum hold-down system would be my suggestion as well
09:39 PM PlaidRabbit1814[: I've tried a few different things on the last machine I used, but I found screws generally did a good enough job, as long as I was careful about the order I cut parts out in.
09:39 PM roycroft: and you can still use mdf as the spoil-board - mdf is porous, and you can use that to your adavantage
09:39 PM PlaidRabbit1814[: I'm not doing so much work that I need to have it hyper optimized. I just don't want to lose material.
09:40 PM PlaidRabbit1814[: I like the spray adhesive idea. When I do smaller bits, I do the blue-tape+CA glue

09:45 PM PlaidRabbit1814[: I haven't had to replace anything super expensive. One bad encoder. Replaced the electronics with Mesa cards & LCNC
09:46 PM XXCoder: nice to hear of lcnc used somewhere :D
09:46 PM roycroft: so from a control point of view it's better than new
09:47 PM PlaidRabbit1814[: Yeah, I just hope the screws on it last long enough to make my project...
09:49 PM roycroft: the base of that machine looks like a mid-century pool table
09:50 PM PlaidRabbit1814[: Pretty much. There's a thick aluminum frame. The gantry is driven by a single ball screw under the table, driven-nut style.

10:12 PM ZincBoy[CAON][m]: I have been having fun putting a laser interferometer together so I can calibrate my machines and measure squareness and straightness. My first target is my old lathe. It has visible wear close to the spindle but now I know how much 🙂
10:12 PM XXCoder: nice
10:14 PM ZincBoy[CAON][m]: What looks like hysteresis in the plot is because the saddle was moved in both directions so there is a difference depending on which direction it is moving.
10:19 PM roycroft: i know how much wear there is on my lathe close to the spindle - more than is acceptable :)
10:21 PM ZincBoy[CAON][m]: If this was a CNC lathe, I could use this as an error map to apply offsets to the axis 🙂
10:23 PM Rab: ZincBoy[CAON][m], awesome! Do you have a writeup anywhere, or is there another project you're copying?

10:27 PM XXCoder: interesting
10:28 PM PlaidRabbit1814[: I dream of one day where we're able to mount interferometer on top of routers, and use that to get hyper accurate positioning. Then all the dust will get in the way and ruin the idea
10:28 PM Rab: ZincBoy[CAON][m], which model of lathe is that?
10:28 PM djdelorie: you'll know exactly where the dust is, though...
10:29 PM PlaidRabbit1814[: Dust location: My entire house.
10:29 PM ZincBoy[CAON][m]: It is an AMC 490. 17x60 A french lathe from the 60s.

10:31 PM Rab: I take it 0 on the plot is at the headstock end of the bed?
10:32 PM ZincBoy[CAON][m]: Yes, the 0 is the headstock. So you can see that it was mostly used from 5 to 25 inches.
11:16 PM PlaidRabbit1814[: Any suggestions on what to use as a spray adhesive for holding sheet aluminum to a MDF spoilboard?
11:17 PM XXCoder: isnt carpet tape good for that? forgot
11:17 PM ZincBoy[CAON][m]: 3m super 77?
11:18 PM ZincBoy[CAON][m]: Not much will really stick aluminum to mdf in an easily removable way. I have used carpet tape as XXCoder mentioned and it worked okay but it tends to gum up bits.
11:18 PM PlaidRabbit1814[: I'm looking for a... sucky adhesive. Not a super-adhesive.
11:18 PM XXCoder: good to know
11:19 PM ZincBoy[CAON][m]: Screws are usually the go-to for this. Otherwise a vacuum table is the best option.
11:19 PM PlaidRabbit1814[: Yeah, I normally use screws, but I'm up for trying something new
11:20 PM ZincBoy[CAON][m]: Screws are reliable. The best other option for small parts was super glue and painters tape.
11:20 PM ZincBoy[CAON][m]: Doesn't work for big sheets though.
11:20 PM PlaidRabbit1814[: Yeah, I've used that as well... and I've used tape and CA glue on 4x8 sheets. It does work... but screws work better
11:20 PM ZincBoy[CAON][m]: Impressive! That must have been a lot of glue 🙂
11:21 PM PlaidRabbit1814[: Not really.
11:21 PM PlaidRabbit1814[: A lot of tape
11:25 PM * roycroft votes for a vacuum clamping system
11:26 PM PlaidRabbit1814[: Give me a reasonably sized vac and the power to run it, run it into my garage and I'm totally up for it.
11:26 PM roycroft: it wouldn't take much
11:26 PM roycroft: as long as it's not leaky
11:27 PM PlaidRabbit1814[: My table actually supports vac already. Just needs some drilling to make it work.
11:27 PM roycroft: folks have used a shop vac on cnc wood routers
11:27 PM roycroft: for sheet metal it would be ideal
11:27 PM roycroft: instant release
11:27 PM roycroft: no worries about running into clamps
11:27 PM PlaidRabbit1814[: I know. Come by my house and install it 🙂
11:28 PM PlaidRabbit1814[: I've used a vac table. It's super nice. I'd love to have it
11:28 PM roycroft: you started out asking for suggestions
11:28 PM roycroft: now you want free labor :P
11:29 PM PlaidRabbit1814[: Heh
