01:35 AM Deejay: moin
04:37 AM Tom_L: morning
05:35 AM JT-Cave: morning
05:36 AM JT-Cave: 53°F
07:54 AM unterhaus_: I saw it was going to be warm today, 51F, and thought that would be a nice change. Of course it's raining, so no mountain biking
08:08 AM JT-Cave: it takes a few days for the trails at Wolf Creek to dry out after a rain
08:15 AM unterhaus_: we have mostly rocks and roots, so the trails are ridable pretty quick. It's just that I'm too wimpy to ride on trails like that.
08:16 AM unterhaus_: hunters are up their trying to bag rats on stilts today, so no riding anyway. Trail system in town is definitely closed though
08:20 AM Loetmichel: rats on stilts???
10:04 AM roguish[m]: JT-Cave: you ok? any twisters in you area?
10:05 AM Tom_L: a little unseasonal for those but i suppose it could happen
10:06 AM roguish[m]: oh, good morning. reached a low of 30.0 this morning about an hour ago. all the way up to 33 now.....
10:06 AM roguish[m]: Tom_L: https://www.nytimes.com/live/2021/12/11/us/tornadoes-midwest-south
10:07 AM Tom_L: requires login
10:07 AM roguish[m]: https://www.theguardian.com/world/live/2021/dec/11/tornadoes-kentucky-deaths-governor-latest-updates
10:07 AM Tom_L: radar is clear for miles around here
10:08 AM Tom_L: east coast might be getting something
10:09 AM Tom_L: i found i the south gets a snowflake they shut everything down
10:09 AM Tom_L: s/i/if
10:15 AM Tom_L: wasn't aware of those tornados, we had some overcast sky yesterday and enough sprinkles to spot the windshield but that's about it. must have grown
10:23 AM roguish[m]: Tom_L: NY Times is paywall. $1 / month digital. kinda liberal but still real journalism.
10:24 AM roguish[m]: TheGuardian is very liberal, but free. pretty good as long as one knows it's liberal.....
10:25 AM roguish[m]: BBC/news is one of the best. pretty independent, and objective. good perspective on the US from an outside looking in.
10:26 AM roguish[m]: SF Chronical. shit news. very liberal, just bad journalism. but good for SF Bay Area events.....
11:40 AM JT-Cave: roguish[m], they went south of us and some north up by St Louis
11:41 AM roycroft: are you talking about the tornados?
11:42 AM JT-Cave: yes, the big one went from Arkansas to Kentucky over 200 miles on the ground
12:05 PM roycroft: i heard
12:05 PM roycroft: and 50-100 dead from that one alone
12:09 PM pcw--home: First really cold morning here ~38F
12:11 PM pcw--home: Our sheep were really funny, all standing up in an equally spaced row facing the same direction, I think for max insolation
12:11 PM roycroft: it's rather blustery here today
12:14 PM pcw--home: We have a little wind here, which is an improvement (we had about 2 weeks of dead still air so a lot of built up smog)
12:39 PM CloudEvil: roycroft: If you hate epoxy river tables, you may also hate: https://www.youtube.com/watch?v=lAVX4Ax70D8
12:40 PM robinsz: so ...
12:41 PM robinsz: runnparport on an old core 2 due ...
12:41 PM robinsz: which release shoudl I try? I will need reasonable performance as I have geckodrives, uStep
12:42 PM robinsz: it sounded like the latest release with the weird kernel might be worth avoiding.
12:43 PM roycroft: hate is a strong word
12:43 PM roycroft: let's just say i find them extremely distasteful
12:46 PM robinsz: Does EMC support the Mesa 7C80 raspi pi thing? http://store.mesanet.com/index.php?route=product/product&path=69_62&product_id=345
12:47 PM robinsz: that would be perfect for my application I think ... if EMC supports it
12:50 PM Tom_L: i think wheezy is the last RTAI release
12:50 PM Tom_L: there is a newer RTAI but you have to build it yourself iirc
12:51 PM Tom_L: rpi4 runs it ok but don't do much else with it
12:51 PM Tom_L: ^^ that card or an ethernet card would work
12:52 PM Tom_L: 7i80, 7i92 etc
12:59 PM pcw--home: The 7C80 is supported by LinuxCNC 2.8.2 Note that the RPI4 may not be the best if you want to run the latest GUIs as RPI graphic libraries tend to lag behind X86
01:01 PM robinsz: OK, I hadn't considered ethernet ... but that might make a lot of sense
01:01 PM robinsz: RPI4 and 7I92M maybe?
01:07 PM robinsz: actually, I think thats the way to go ... 7i92 and some sort fo breakout
01:09 PM robinsz: I can be flexible then as to what the controller is ... RPI4 woudl be nice with the RPI standard screen.
01:14 PM roguish[m]: pcw--home: Peter. my dc drives have a voltage/current output to monitor current. what could i use to monitor the voltage into linuxcnc. it's like 3.5v/amp. max 20amp output....
02:27 PM pcw--home: 70V full scale? that seem pretty high, sure its not 0.35V/A?
02:35 PM Tom_L: or what's that newer all in one ethernet card ?
02:35 PM Tom_L: 7i96?
02:35 PM Tom_L: robinsz, might be another choice
02:42 PM JT-Shop: 7i76E, 7i95, 7i96 are all Ethernet stepper cards
02:42 PM Tom_L: the 96 is the all in one isn't it?
02:44 PM JT-Shop: all of those are all in one
02:44 PM JT-Shop: just different I/O count mainly
02:44 PM Tom_L: ok
03:50 PM JT-Shop: https://mesaus.com/product-category/ethernet-cards/
03:50 PM JT-Shop: easy to see the difference on that page
03:59 PM Tom_L: 'sourcing' is the positive side right?
04:04 PM JT-Shop: yea sourcing outputs mean the send 24vdc out
04:04 PM JT-Shop: sinking the 24v comes from the device and the common is 0VDC
04:10 PM Tom_L: what is most common in industrial applications?
04:12 PM JT-Shop: sourcing outputs and sinking inputs
04:23 PM robinsz: I need very little IO, this little mill doesnt even have any limit switches (yet)
04:25 PM robinsz: I think I'll order the 7i92M with the male 25 pin ... and the 7i78 breakout with the femal 25 pin and I can just plug them together
04:25 PM Tom_L: plan ahead...
04:26 PM robinsz: the 92 has a 26 way for "other stuff" should it ever get as far as limit switches
04:26 PM Tom_L: i used nearly every available io on my 7i47s and a few on another port
04:26 PM Tom_L: you want a pendant?
04:26 PM Tom_L: you want spindle control?
04:26 PM robinsz: no
04:26 PM Tom_L: you want coolant control?
04:26 PM robinsz: no
04:27 PM Tom_L: just saying...
04:27 PM JT-Shop: if there was any 7i96's that's the best choice...
04:27 PM Tom_L: you out of stock?
04:27 PM robinsz: this card will be in the box with the steppers
04:28 PM JT-Shop: 7i92M + 7i78 is good too
04:28 PM robinsz: if I want buttons, I'll do thr RS422 dance
04:28 PM JT-Shop: yep no 7i96's
04:28 PM Tom_L: damn this economy...
04:28 PM robinsz: the 78 has RS422 extender out I think
04:28 PM robinsz: yeah, we're screwed on some of our electronics stuff at the moment
04:28 PM Tom_L: does the 7i76 have an analog out for spindle?
04:29 PM JT-Shop: yep
04:29 PM Tom_L: cool
04:29 PM robinsz: common parts no longer common
04:29 PM JT-Shop: yes the 7i78 has a RS-422 port for smart serial cards
04:29 PM JT-Shop: https://mesaus.com/product/7i78/
04:29 PM robinsz: that will more than cover me then
04:30 PM JT-Shop: https://mesaus.com/product/7i92m/
04:30 PM JT-Shop: I have a very few of each in stock
04:31 PM robinsz: thats that Australia store?
04:31 PM robinsz: wait, no, im reading that wrong
04:31 PM JT-Shop: no, I'm in the USA but I ship to AU
04:32 PM robinsz: is that the same as store.mesanet.com?
04:33 PM JT-Shop: no, I'm the USA dealer
04:33 PM robinsz: right, got it.
04:37 PM robinsz: Ah poop, you don't ship to the UK
04:39 PM JT-Shop: aye they (UK) has new regulations about imports that make it a PIA for anyone to ship there but I suppose I could send a gift?
04:41 PM robinsz: Europe is going the same way
04:41 PM robinsz: infact did go the same way in July but no one has noticed
04:44 PM JT-Shop: aye I shipped a part to a guy in Germany the other day marked gift
04:45 PM JT-Shop: UK requires me to open an account with them and pay duties on anything below some value
04:45 PM JT-Shop: some use freight forwarders that has a usa address
04:47 PM robinsz: in theory .. yes. in practice, because of COVID, stuff is just arriving as it always did
04:48 PM JT-Shop: really
04:48 PM robinsz: I got a 60lb box of feeders for my SMT pick and place out of Ohio this week, went on UPS as normal
04:49 PM robinsz: arrived with a smile from the UPS guy, nothign else. I put the value at $300 too
04:50 PM JT-Shop: that's good to know
04:50 PM JT-Shop: and UPS is the only way to ship international now
04:52 PM robinsz: UPS never lose anything ... I ship audio amplifiers, in the $800 to $2000 range, never even use the insurance
04:54 PM JT-Shop: that's good to know
05:33 PM robinsz: Right then, that's the hardware sorted ... I can unbolt the "deskCNC" controller and beat it to death with hammers
05:38 PM * JT-Shop hands robinsz a copy of Bob Crap to put with the deskCNC
05:45 PM robinsz: good god ... I'd forgotten about that steaming pile ...
05:45 PM robinsz: I use Vectric Cut2D pro these days
05:46 PM robinsz: the big 8x4 router runs on EMC with a mesa card and servos
05:47 PM robinsz: we drive it with Cut2D, I figure on using it with the little mill in the shed too
05:48 PM robinsz: Something that did 3D contouring from STL or IGES would be nice, but I can't afford mastercam
05:48 PM JT-Shop: aye Bob Crap came with my first BP knee mill with an Anilam conversion on it
05:48 PM robinsz: Maybe fusion360 is worth a try, but I am normally allergic to anything Autodesk related
05:48 PM XXCoder: meh
05:48 PM XXCoder: cloud stuff
05:49 PM JT-Shop: I'm allergic to cloud anything
05:49 PM XXCoder: very locked down on what you can do. 10 part limit too if I recall right
05:49 PM robinsz: is it not a local application?
05:49 PM JT-Shop: robinsz, pm
05:49 PM JT-Shop: fusion360 is installed but must phone home a lot
05:51 PM robinsz: euw.
05:51 PM XXCoder: yeah, keep avoiding autodesk
05:52 PM robinsz: I think the "personal" edition is fairly "unlocked"
05:52 PM _unreal_: I own fusion
05:52 PM _unreal_: robinsz, have you ever heard of designspark?
05:52 PM robinsz: nope
05:52 PM _unreal_: :)
05:53 PM XXCoder: no, you RENT fusion
05:53 PM _unreal_: https://photos.app.goo.gl/CuUszxKaFziVnQKX9
05:53 PM _unreal_: robinsz, there are some exapmles of stuff I've done
05:54 PM _unreal_: XXCoder, regardless
05:54 PM XXCoder: no
05:54 PM robinsz: oh wait, the RS PCB tool?
05:54 PM XXCoder: there is HUGE difference between sub model and own program
05:54 PM _unreal_: robinsz, palm to face sigh
05:54 PM _unreal_: NO
05:55 PM _unreal_: designspark produce a bunch of software flavors
05:55 PM robinsz: oh thats waht came up in my search
05:55 PM _unreal_: ONE is cad, one is PCB one is other
05:55 PM _unreal_: etc....
05:55 PM robinsz: dont need cad, need CAM
05:55 PM robinsz: I have Solidworks for CAD
05:55 PM _unreal_: https://www.rs-online.com/designspark/mechanical-download-and-installation
05:55 PM _unreal_: its totally free
05:56 PM robinsz: but is it CAM?
05:56 PM _unreal_: it does not have a built in CAM no..
05:57 PM _unreal_: but it runs circles around every other CAD software I've used
05:57 PM * JT-Shop wanders inside to cook some jambalaya
05:57 PM robinsz: I'll pass, I have Solidworks
05:57 PM JT-Shop: what year SW?
05:57 PM _unreal_: ?
05:57 PM Tom_L: good to see the devel channel busier than here for a change
05:58 PM robinsz: Oh not recent ... like, 2010 when the company I was with last paid for an upgrade
05:58 PM robinsz: but, it does all I need
05:58 PM JT-Shop: ah ok 2014 they started adding CAM for free
05:58 PM robinsz: bummer.
05:58 PM Tom_L: oh yeah?
05:58 PM Tom_L: how is their post to modify?
05:59 PM JT-Shop: I have 2014 but have OneCNC that works for me
05:59 PM XXCoder: jt thats interesting. too bad solidworks is so expensive :(
05:59 PM JT-Shop: so I've never tried the CAM
05:59 PM Tom_L: bugger
05:59 PM robinsz: this one is a real paid for one too, with an actual dongle
05:59 PM Tom_L: i'm set up but always like to see what works
05:59 PM JT-Shop: when we were making machines left and right for Briggs and Stratton I kept SW up to date
05:59 PM _unreal_: I use designspark mainly for CAD and fusion for the cam
05:59 PM _unreal_: I also use ESTLcam
06:00 PM _unreal_: I own estl
06:00 PM JT-Shop: anyhow time to cook
06:00 PM JT-Shop: see you guys later
06:00 PM Tom_L: bye
06:00 PM _unreal_: not if we see you first
06:00 PM * Tom_L feeds _unreal_ to a crock
06:00 PM roguish[m]: ttfn
06:01 PM JT-Shop: unterhaus_, I did manage to size the material for your part today!
06:01 PM Tom_L: JT-Shop, is peter switching fpga chips?
06:01 PM Tom_L: gonna be harder to keep track of things
06:03 PM robinsz: I dont understand what ESTLcam is
06:03 PM robinsz: is it cam?
06:03 PM Tom_L: the name implies that
06:03 PM XXCoder: it is, but not amazing one. works when I tested it
06:04 PM robinsz: and if it is cam, why does it have a handwheel and a parallel port interface?
06:04 PM robinsz: and specific machine interfaces
06:04 PM Tom_L: you have to hand crank it to start it
06:04 PM robinsz: figue
06:04 PM robinsz: s
06:04 PM robinsz: r
06:04 PM XXCoder: it USED to be just cam
06:04 PM robinsz: sigh ...
06:04 PM XXCoder: then they crammed cnc control into it
06:05 PM robinsz: rule one .. do one thing and do it well
06:05 PM XXCoder: making it messy
06:05 PM XXCoder: indeed
06:05 PM robinsz: I'll stick with Vectric for my cam
06:05 PM roguish[m]: pcw--home: you're right. 3.8 a/v
06:05 PM XXCoder: doubled price too I think, to add thing I would never use. not with lcnc
06:05 PM robinsz: sigh
06:06 PM XXCoder: actually cheaper now
06:06 PM XXCoder: 59 usd
06:06 PM robinsz: that is cheap
06:06 PM Tom_L: worth 10?
06:06 PM XXCoder: it was 80-90, so I guess guy reverted price
06:07 PM XXCoder: meh still dunno if worth it. might be for me, because its so hard to have cam on linux
06:07 PM robinsz: I use this https://www.vectric.com/products/cut2d-desktop
06:07 PM XXCoder: freecad also has Path, which is a cam, but never used that
06:08 PM pcw--home: Tom_L: "JT-Shop, is peter switching fpga chips?" Looks like we will be forced to (>50 week lead times on Xilinx and Altera (intel) FPGA chips)
06:08 PM Tom_L: so many get halfway into it and fall short of the finish line
06:09 PM Tom_L: pcw--home, yes i remember you mentioning that a while back
06:10 PM roguish[m]: pcw--home: you are correct. drive output is 3.8 A/v
06:10 PM pcw--home: Currently doing battle with the Efinix tool chain. I seem to be winning, but its a bit too early to tell
06:10 PM Tom_L: no more free tools ehh?
06:10 PM pcw--home: Efinix makes you buy a devel card to get the tools
06:10 PM Tom_L: oh
06:10 PM _unreal_: efinix?
06:11 PM robinsz: try looking at lead times on some Ti PSU chips ...
06:11 PM robinsz: some of it is more than 2 years out ...
06:11 PM pcw--home: Lattice has open source tools but they are still like 36 week lead times
06:11 PM Tom_L: you having to change the source quite a bit to make it happy?
06:11 PM pcw--home: Not too much
06:11 PM Tom_L: that's good
06:11 PM pcw--home: the top level needs some changes
06:12 PM robinsz: if China does Bad Things(tm) to Taiwan, we are going to be knocked back decades
06:13 PM Tom_L: mesaflash will be different too i suppose
06:13 PM pcw--home: Yeah $0.75 power supply chips from Allegro we use are ~30 weeks
06:13 PM robinsz: I have several products just screwed for PSU chips ... I re-designed two, prototyped them and then that went out of stock too!
06:13 PM pcw--home: Yes, need to support reconfiguration and choosing images which is different on Efinix
06:14 PM pcw--home: (mesaflash needs additions)
06:15 PM pcw--home: Funny thing is that Efinix P&R is using an open source tool (VPR)
06:16 PM Tom_L: maybe that's why they sell you the dev board instead of the software
06:16 PM pcw--home: roguish[m], yeah if you have a sserisl interface you coul run a 7I87 to read that (or if you have a 7I76E,7I76,7I77, those all have analog inputs)
06:16 PM Tom_L: lattice wasn't free either was it? iirc...
06:17 PM pcw--home: Lattice does have a free toolchain (not sure about their GUI stuff)
06:20 PM pcw--home: I have one sample hostmot2 config running on the Efinix Dev card (did need to work around one synthesis bug to get it going)
06:21 PM enleth: Tom_L: lattice can be done 100% free and open
06:21 PM enleth: shame they also got hit with supply problems
06:21 PM roguish[m]: pcw--home: ah, have a 7i80 don't think it has SSI
06:21 PM Tom_L: ssi?
06:22 PM Tom_L: serial?
06:22 PM pcw--home: It needs a RS-422 interface for SSerial
06:22 PM Tom_L: the 7i80 needs some sort of daughter card anyway
06:23 PM Tom_L: i managed to get all 4 axis w/spindle on the 7i47s
06:23 PM robinsz: there seem to be some cheap chinese "tool height sensors" on fleabay
06:23 PM robinsz: https://www.ebay.co.uk/itm/363639853973
06:23 PM robinsz: they look ... well, cheap?
06:24 PM Tom_L: i got a manual one with a dial for my kid at his work
06:24 PM _unreal_: thats expsnive for a touch sensor :S
06:25 PM _unreal_: ali. has them for $3
06:25 PM robinsz: I have a manual one with a dial, a nice one too
06:26 PM robinsz: but I was thinking of something automatic for this machines, as it is collet for tools
06:26 PM robinsz: not proper holders
06:26 PM Tom_L: https://www.ebay.com/itm/301203002700
06:26 PM Tom_L: similar
06:27 PM robinsz: I have one of those, well similar
06:27 PM robinsz: https://assets.allendale-metrology.co.uk/media/catalog/product/cache/04896bff58578232dacde025d9397067/imp/ort/Edge-Technology-Touch-Off-Gage-52-000--20180808_115917.jpg
06:28 PM robinsz: but I was thinking of an electronic touch off for this little machine
06:28 PM Tom_L: i saw that variation too
06:35 PM enleth: pcw--home: the one upside of the situation is that now, after you've been forced to investigate and test alternatives, you'll be able to switch FPGA vendors in the future with much less hassle even for much less pressing reasons
06:40 PM pcw--home: Yes, its good to keep flexible.
06:44 PM roguish[m]: pcw--home: don't want to rewire, so i'lll find something independent... i hope. it's just for curiosity
06:46 PM pcw--home: If its not realtime you could use some simple USB device
06:46 PM _unreal_: there just finished a CAD drawing for an adapter
06:47 PM _unreal_: converting these parts that comes from. sat's. to be a lead screw driver
06:47 PM _unreal_: they have VERY heavy duty bearings
06:48 PM roguish[m]: doesn't have to be realtime. just close. I have some small voltmeters, just need to figure out how to do the scaling so I get proper amperage.
07:35 PM JoseIgnacioRomer: <robinsz> "there seem to be some cheap..." <- I didnt realize those were so cheap, i just grabbed one.
07:57 PM Bleepshop: D'Oh! Spent all afternoon trying to source some stranded16-4 with a shield for my new spindle drive cable in Santa Fe and failed miserably... Just started to add the new tubing for water cooling, air and mist [2x8mm 2x6mm] and realized I had already used shielded 14-4 when I had to rewire it after I got it and doubled up blk/red and wht/green to make sure the router had solid power. LOL
08:05 PM roycroft: i dropped a 1/2" stubby wrench down the column of my bandsaw, and have not been able to retrieve it
08:06 PM roycroft: i also dropped my heat gun that i bought in the early '80s and have been using all that time for shink tubing, and the fan broke
08:06 PM roycroft: i have decided to repair the heat gun instead of replacing it
08:06 PM roycroft: retrieving the wrench is going to be very difficult, though
08:07 PM roycroft: it will probably require tipping the saw on its side, amongst other acrobatic maneuvers
08:08 PM roycroft: the plan was to finish the wiring today, test, then remove the junction box and paint it
08:08 PM roycroft: i'm not finished with the wiring yet, though, due to those issues
08:09 PM roycroft: the latest fun was the motor wiring diagram
08:10 PM roycroft: jet printed the wiring diagrams for 120v and 240v on with very tiny, skinny black print on a shiny silver foil background, and taped them onto the inside of the motor cover, which is plastic and has reinforcing ribs
08:10 PM roycroft: so it's kind of crumpled up
08:11 PM roycroft: i had to remove the stickers, put them under bright lights, then use a magnifying glass to read them
08:11 PM roycroft: but now they are redone, printed in black on white on stiff, matte card stock, and i can read them easily at a distance
08:12 PM XXCoder: no way to use magnet or something
08:12 PM XXCoder: wire and magnet
08:12 PM roycroft: i tried for about 2 hours
08:13 PM roycroft: i finally decided to get on with the wiring, and while the j-box is in paint, i'll top the saw over and retrieve it
08:20 PM roycroft: the problem with tipping the saw over is that i built an mdf base for it that sits on casters
08:20 PM roycroft: it's very strong, and could easily support 4x the weight of the saw
08:20 PM roycroft: but if i try to tip it over while it's on the casters it will almost certainly tear the casters off the bottom of the cabinet
08:21 PM roycroft: so i'll have to remove the saw from the base, and then top the saw down
08:21 PM XXCoder: bleh
08:21 PM roycroft: that will probably take a couple or three hours to do, including reassembly
08:21 PM XXCoder: probably can 3d print something to cover hole so stuff dont fall in it again lol
08:21 PM roycroft: and hopefully it won't take long to retrieve the wrench
08:22 PM XXCoder: or add another hole to bottom rear lol
08:22 PM roycroft: well i'll have no need to ever stick a wrench inside that column again
08:22 PM Tom_L: magnet won't reach it?
08:22 PM roycroft: the saw column is steel
08:22 PM roycroft: it's a narrow channel
08:22 PM Tom_L: still worth a try
08:22 PM roycroft: i spent a good 90 minutes trying
08:22 PM Tom_L: magnet on a stick
08:22 PM XXCoder: i got a idea. 3d print small ball (bit smalelr than column) and have magnet on bottom of it
08:22 PM XXCoder: so it wont stick to walls
08:23 PM roycroft: it goes down 3 feet from the opening
08:23 PM roycroft: making a standoff is not a bad idea, actually
08:23 PM roycroft: but instead of 3d printing something, i could drill a hole in a piece of wood and stick the end of the magnet into the hole
08:24 PM roycroft: i'll sort that later
08:24 PM XXCoder: cool
08:24 PM roycroft: i want to get the wiring done, and the j-box in paint
08:24 PM roycroft: i also droppd a 3/8" nut down that hole
08:24 PM roycroft: i'm not worried about the nut except if it starts vibrating when the saw is powered on it will drive me nuts
08:25 PM roycroft: so i'll try to retrieve that as well
08:25 PM XXCoder: hard metal music?
08:26 PM roycroft: i think the universe was telling me to stay out of the shop today
08:27 PM XXCoder: lol
08:55 PM Bleepshop: roycroft stuff a neodynium magnet in the end of a piece of rubber hose. That should solve your wrench issue.
08:57 PM Bleepshop: It'll only stick end-on that way and you can twist it to break it free to get it down there.
08:59 PM roycroft: i'm going to give it another go before i dismantle the saw and tip it over
09:04 PM Bleepshop: If it's a straight shot down to it use a short length of hose on a dowel with the magnet in the end.
09:06 PM * Bleepshop is getting ready to drill and tap the holes in the old Z mount for the new spindle mount.
09:09 PM roycroft: i have to go through an opening in the side of the column, so i can't go straight down
09:09 PM roycroft: but i'll figure something out
09:09 PM Bleepshop: Transfer punches, clamps and steel blocks make this so easy. LOL
09:09 PM roycroft: if i'm honest, i'm more concerend with repairing my heat gun than retriving that wrench
09:09 PM Bleepshop: roycroft: Thick hose with a magnet in it.
09:10 PM roycroft: i've had the heat gun since the early '80s, and i've used it thousands of times on heat shrink
09:10 PM roycroft: replacing it would be like losing an old friend
09:10 PM Bleepshop: roycroft: Go parametric on the fan and 3D print a new one out of ABS ?
09:11 PM roycroft: i'll have to dismantle it and see what's inside
09:11 PM roycroft: hopefully it will be repairable
09:11 PM Bleepshop: Find a donor [willing or not] and do a transplant? LOL
09:13 PM roycroft: it's hard to believe i've never dropped it in the ~40 years i've had it
09:13 PM roycroft: until today, of course
09:45 PM roycroft: it appears that my heat gun is still being made
09:45 PM roycroft: which increases the chance i can purchase parts for it
09:46 PM roycroft: https://www.masterappliance.com/master-mite-heat-gun/
09:48 PM roycroft: the manufacturer also offers a flat-rate repair service fro $57
09:51 PM roycroft: and they're quoting a 1 week turn-around on repairs
09:51 PM roycroft: if i cannot easily repair it myself that's a good option
09:53 PM roycroft: the replacement fan motor is $50, so if i need that, i'll almost certainly just send it in to them for repair
10:21 PM * Bleepshop does the happy dance.
10:21 PM Bleepshop: Woohoo! The new spindle is mounted and ready to wire/plumb.
10:22 PM Tom_L: so git r dun
10:24 PM Bleepshop: I will as soon as I find my old roll of real pb/sn/ag silver bearing solder. There it is. Archer 64-013.
10:26 PM Bleepshop: Around here the stuff gets saved for extreme vibration enviroment work. I'm gonna use it here as a safeguard.
10:31 PM roycroft: i don't have my new spindle yet
10:31 PM roycroft: it's due to arrive before the end of the year, though
11:04 PM _unreal_: so I just broke into the "laptop" I was given by my elderly neighbor. she thought it was the latest and greatest. :S 4gb RAM, 1.6ghz something something cpu more or less a super charged atom cpu
11:04 PM _unreal_: ugh
11:04 PM _unreal_: its a slug in win10 and usable in linux
11:04 PM roycroft: so it would make a perfectly respectable linux machine
11:05 PM _unreal_: dont really have much of a use for it
11:06 PM _unreal_: you know its slow when you open "cheese" and go to the camera effects, discover the display has a 640 res web cam built in. and it CHOPS along trying to show the video effects
11:06 PM _unreal_: thats kind of my go to cpu benchy
11:07 PM _unreal_: though when I say BROKE into the laptop I just mean I booted it with a linux disk
11:07 PM _unreal_: heh
11:19 PM Bleepshop: _unreal_: I bet you're one of those 'hackers' who reads HTML source too... ;D
11:21 PM * Bleepshop is the worst kind of hacker...
11:21 PM _unreal_: hardly
11:21 PM _unreal_: I'm a hardware guy not a software guy
11:21 PM Bleepshop: I could probably still code an HTML 4.0 compliant page in my sleep... xD
11:22 PM _unreal_: the last time I delt with htlm code I was in high school
11:23 PM Bleepshop: _unreal_: I've had to be both and more over the years. I wrote an entire inventory system for a wrecking yard back in 1999 that ran via a web backend to track parts available/sold.
11:27 PM _unreal_: Bleepshop, how are you with stm32?
11:28 PM Bleepshop: Never used one. Got one in a drawer that's setup as a GRBL board to install in my PC board mill eventually.
11:29 PM _unreal_: My laser etcher currently is setup with arduino GRBL i want to convert to stm32 just dont have any way ot compiling for the stm32
11:30 PM * Bleepshop trys to remember the name of the tftp booting, X11, thin clients.
11:30 PM Bleepshop: _unreal_: Are you near a linux box ?
11:30 PM _unreal_: no
11:30 PM _unreal_: my main linux box has been down for some time and I have not had time to rebuild it
11:32 PM Bleepshop: OK... Find a >32GB USB drive and install a Live image to it, then add gcc, etc, etc. ?
11:32 PM _unreal_: I could do that
11:32 PM Bleepshop: Hell! Put it on that laptop and let it grind for a week. LOL
11:35 PM Bleepshop: Drop to 'multi-user' or 'runlevel 3' and run srtraight CLI if oyu can. It makes old hardware decent compilers.
11:36 PM * Bleepshop has 3 headless boxes running right now and just uses 'ssh -X' when needed.
11:40 PM _unreal_: ya I use to do that a bit. but I just have no room. long story short I'm stuck in a living situation that is just killing me.
11:54 PM Bleepshop: Heh. I've been pretty much living in my workshop to get away from the extreme 'Sit on ass and vegitate' vibe going on in the house. LOL
