02:15 AM MrSunshine: hmm, mesas default state of pins when not configured is high, the breakout board when a signal is high ties the output to gnd .. so it enables the output on the breakout board .. is there any clever way to connect this so that signals to make the state safe, as in low when starting up the machine? =)
02:38 AM Deejay: moin
03:41 AM t4nk_freenode: I say good morning, good morning.
04:33 AM wonderer: t4nk_freenode a g'day to you
04:34 AM Deejay: good day to you
05:08 AM JT-Cave: morning
05:19 AM Tom_L: morning
06:41 AM CaCtus491: Evening all
08:50 AM unterhaus: I was going to answer a user question on the developer list but decided against it
08:51 AM unterhaus: apparently someone didn't like the response they got here about the difference between mach ethernet and mesa ethernet
08:51 AM Tom_L: didn't wanna be ridiculed?
08:51 AM Tom_L: oh that guy
08:51 AM unterhaus: I think the noise level should be reserved for user list
08:52 AM Tom_L: i just unplug the speakers :)
08:52 AM unterhaus: somehow I don't think it bothers the devs if there is no traffic on their list, unlike some users
08:52 AM Tom_L: yeah not on the dev list.. it's sacred
08:55 AM unterhaus: at least I got the worst offender to stop asking questions about his email server on the dev list
08:56 AM Tom_L: that ether board i saw the other day probably _could_ be reflashed to work but alot of the firmware would have to be changed
08:57 AM Tom_L: i'd guess about 2/3 or more of those that want major change aren't prepared to make those changes
09:00 AM unterhaus: yeah, there is some potential with the mach hardware
09:01 AM unterhaus: although the existence of usb mach hardware is a bit of a pain because it drives questions
09:02 AM unterhaus: I assume it really means that mach is equivalent to a gcode sender now, only with a proprietary protocol
09:32 AM unterhaus: there is a lcnc driver/firmware for the nvum mach 3 board, correct? Remora branch, I think
09:36 AM unterhaus: there is, I wonder if it works on the $100 version
09:40 AM satiowadahc[m]: This spindle bug is killing me this weekend... anyone know how `import emccanon` and `import interpreter` work?
09:40 AM satiowadahc[m]: I see they're exported after task boots, but I don't see how to use them
09:40 AM Tom_L: could be a devel question if you wanna know how the innards work
09:41 AM satiowadahc[m]: Ah so keep devel out of user, and user out of devel? I may have to resort to this
09:42 AM Tom_L: no just keep user out of devel :)
09:42 AM Tom_L: someone here may know but more likely in devel
09:43 AM satiowadahc[m]: Fair enough
09:44 AM unterhaus: is there an issue for the "spindle bug"?
09:45 AM Tom_L: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?EMC_Components
09:45 AM satiowadahc[m]: https://github.com/LinuxCNC/linuxcnc/issues/1714
09:46 AM satiowadahc[m]: Its manual vs mdi, command.spindle issues to task but the interpeter has no knowledge of it
09:47 AM satiowadahc[m]: so command.spindle(Forward, RPM, spindle) and then mdi s another speed will shut the spindle off
09:49 AM unterhaus: yeah, looks like a linuxcnc-devel question.
09:49 AM Tom_L: also easter weekend so it could be a bit sparce in either place
09:51 AM satiowadahc[m]: Yea, I hate leaving a bug unsolved on a Friday as it sits on my mind all weekend. Hard to leave it alone.
09:52 AM satiowadahc[m]: or Thursday of a long weekend
09:52 AM Tom_L: it could have come about when they added multiple spindle support
09:52 AM Tom_L: also what ver are you working with?
09:53 AM satiowadahc[m]: Master
09:53 AM Tom_L: have you tested it in 2.8?
09:53 AM Tom_L: helpful to know where it broke
09:54 AM satiowadahc[m]: Not yet... avoiding gtk2 and python2 on this machine...
09:54 AM Tom_L: the more you can tell the quicker it will get resolved more than likely
09:58 AM satiowadahc[m]: Imma see if I have a spare machine to test it on.
10:20 AM _unreal_: More cad work
10:26 AM * roycroft is doing cad work this morning as well
11:38 AM _unreal_: I'm cutting it tight but it looks like a lot of the stuff I didnt think was going to work will
11:39 AM _unreal_: with the new X Z build for the bigger cnc machine
11:39 AM _unreal_: I might even start doing some cutting
11:39 AM _unreal_: this weekend
11:42 AM t4nk_freenode: ah, so you're finally set to rake in the beacoup bucks with the machine then ey :b
11:56 AM _unreal_: hardly
11:56 AM _unreal_: needs to be a working system first
11:56 AM t4nk_freenode: mmmm
11:56 AM _unreal_: right now I'm cad WORKING
11:56 AM _unreal_: today I may start milling some of my parts on my small cnc machine
11:57 AM _unreal_: depends on what goes on today
11:57 AM t4nk_freenode: well I guess you can always cash in on some of those stocks, to wet your whistle
11:57 AM _unreal_: hardly
11:57 AM _unreal_: need to be in the green
11:57 AM t4nk_freenode: :(
11:57 AM _unreal_: most of my stocks are down 50-70%
11:57 AM t4nk_freenode: they aren't right now??!
11:58 AM _unreal_: every time there is a strong democrat rule in the US GOV. all markets tank
11:58 AM _unreal_: My big play right now is AMC
11:58 AM _unreal_: AMC and sndl
11:58 AM _unreal_: if WEED gets legalized at the FED level. I'm a millionair,
11:59 AM _unreal_: with the volume of stocks I have
12:00 PM _unreal_: if any thing sets off a market wide short squeeze. I'm likely a millionaire with AMC
12:00 PM t4nk_freenode: *sigh* well then, I guess you can always scour the waste bins outside for some usable scrap?!
12:00 PM t4nk_freenode: :b
12:00 PM _unreal_: sndl if they legalize it it will run to $50 likely hit $100
12:01 PM _unreal_: if I can get upto 20k shares of SNDL I'm a millionaire at $50 strike price
12:01 PM t4nk_freenode: youknow.. sometimes... a stock that was at $100... can go all the way down to 1ct a pop!
12:02 PM _unreal_: thats the problem I have right now
12:02 PM t4nk_freenode: and then you get a call, with an offer to buy them from you for 0.02cts, take it or leave it
12:02 PM t4nk_freenode: and you leave it
12:02 PM _unreal_: and I got SCREWED every one got screwed on MMAT dividend BS last year
12:02 PM t4nk_freenode: and it all goes
12:02 PM t4nk_freenode: you'd think I'd be kidding you, but I'm really not
12:03 PM _unreal_: I have thousands tied up in MMAT that I dont have the cash to average down. and a year later they still have not payed the dividend yet
12:05 PM _unreal_: I get my dividend that should be a payment between $12k-$40k depending on the end value likely in the higher middle range. So GOD DAMN tired of waiting.
12:08 PM _unreal_: My energy stock play didnt play out at all thanks to SHIT HEAD biden team killing the energy market, I was afraid that would happen too.... :( I should have made about $20k-52k few months ago on my energy stock play. but NOOOOOOO.... no energy stocks moved..
12:11 PM _unreal_: man these are going to be some big cuts on my little cnc machine
12:11 PM _unreal_: will be working it right to its limits
12:11 PM _unreal_: work area wise
02:49 PM JT-Shop: second drawer came out nice
02:49 PM XXCoder: yay
02:49 PM JT-Shop: used red oak
02:49 PM XXCoder: what you use for coating it?
02:50 PM JT-Shop: plus I'm experienced now lol
02:50 PM JT-Shop: prob Tried & True Varnish Oil
02:51 PM JT-Shop: https://gnipsel.com/images/wood-working/table-top/table-top-02.jpg
02:51 PM JT-Shop: that's right after applying it
03:06 PM Tom_L: damn that looks expensive!
03:20 PM XXCoder: JT-Shop: impressive lol
03:20 PM XXCoder: probably some sand and paint, couple cycles and it will look amazing and feel very smooth
03:20 PM XXCoder: because of removal of rised fibers
04:05 PM JT-Shop: https://gnipsel.com/images/wood-working/table-top/
04:05 PM JT-Shop: that's all the photos of the table rebuild
04:05 PM JT-Shop: just glued the egg drawer and I'm happy with the way it came out
04:06 PM XXCoder: nice
04:06 PM XXCoder: it'd be great restore video lol
04:07 PM XXCoder: you used surface grinder to make wood even? I saw first picture its extremely uneven
04:08 PM XXCoder: whatev ah I think its called planer?
04:10 PM JT-Shop: 1 is sorted for glue up
04:11 PM JT-Shop: 2 is in position for glue up but as you can see they are different thicknesses (first one rotated 1/4 turn CCW rest are 1/4 turn CW
04:12 PM JT-Shop: 3 the boards are flipped over and put in clamps with the glue surface down making it a level surface
04:12 PM JT-Shop: 4 back to the original clamps with the glue surface up
04:12 PM JT-Shop: 5 ready for glue, 6 glue spread
04:13 PM JT-Shop: 7 flipped back and clamped up for gluing, notice they are all now the same thickness
04:14 PM XXCoder: ahh ok :D
04:14 PM JT-Shop: 8 skipped a few steps, each 6" board goes over the jointer to smooth the bottom and one edge then two pairs are glued together
04:15 PM JT-Shop: then those are glued into one big panel and that goes under the drum sander on both sides until smooth to 60 grit
04:15 PM JT-Shop: then hand sanding down to 320 grit with the orbital sander
04:16 PM JT-Shop: 10 is the finished top after burnishing with 0000 steel wool
04:16 PM XXCoder: thats good. get rid of risen fibers :D
04:17 PM JT-Shop: steel parts were all blasted clean and either powder coated or painted
04:17 PM XXCoder: powder coat nice. that'd make it so tough
04:17 PM JT-Shop: turned out pretty good for a shop table lol
04:17 PM XXCoder: I do want to learn how to powder coat
04:17 PM XXCoder: its now too good to be a shop table, bring it in ;)
04:17 PM XXCoder: kidding
04:17 PM JT-Shop: I was concerned about powder coating the tables they were so thin I was afraid they might warp
04:18 PM JT-Shop: surface prep is important with powder coating
04:20 PM * JT-Shop wanders down to the chicken yard to make some chicken crack
04:22 PM XXCoder: yeah removal of oils and such
04:23 PM XXCoder: dont know much more than that but I do want to try em someday lol
04:34 PM JT-Shop: well you blast off any old coatings the flash off any volatiles at 350°F for 30 minutes, after the parts are cool apply powder then bake it on
04:34 PM JT-Shop: then flash off
04:35 PM XXCoder: flash off?
04:36 PM JT-Shop: 350°F is hot enough to make any volatiles flash off or vaporize
04:37 PM XXCoder: ahh ok but do it twice? including after powder and bake?
04:38 PM JT-Shop: you flash off the volatiles before powder coating
04:38 PM CloudEvil: You're supposed to apply powdercoat cool.
04:38 PM JT-Shop: but yes each part goes in the oven twice
04:38 PM JT-Shop: that's what I said
04:38 PM XXCoder: ok making sure I understood. thanks
04:38 PM CloudEvil: Indeed.
04:39 PM CloudEvil: If it's very clean you might be able to skip the first bake, but any trivial contaminents you don't know about will fuck you up.
04:39 PM JT-Shop: yup
04:39 PM CloudEvil: 350F will either fully evaporate, or oxidise most contaminents to the point it's much less critical.
04:41 PM CloudEvil: Finishing is fun.
04:42 PM JT-Shop: I put screws in any threaded holes and as soon as I pull out of the oven I back them out 1/4 turn
04:42 PM XXCoder: preserving threads, and preventing bolts being perment eh
04:42 PM JT-Shop: makes for a nicer looking product
04:43 PM Tom_L: that way it doesn't pull the paint
04:44 PM JT-Shop: now that I know the exact dimensions of the egg drawer I can start on the sides and back of the egg protective device
04:44 PM JT-Shop: yup or the powder
04:44 PM CaptHindsight[m]: JT-Shop: which brand of powders do you use?
04:45 PM JT-Shop: Columbia
05:19 PM XXCoder: JT-Shop: using datum lines for first time in freecad. whee
05:19 PM XXCoder: im trying to make VERY complex shape
05:20 PM XXCoder: https://imgur.com/mj1ell6.png
05:20 PM XXCoder: just starting
05:23 PM Tom_L: what is it?
05:23 PM XXCoder: its new cpap hose holder
05:24 PM XXCoder: it should easily allow hose to slide in and out without snagging
05:24 PM XXCoder: older design worked but had few snag spots
05:24 PM XXCoder: https://www.printables.com/model/60205-cpap-holder-for-ikea-bed if curious
05:26 PM XXCoder: what I plan to do is once im done with shaping that, I'll cut it into boxlike similiar to old design
05:29 PM Tom_L: spun surface?
05:29 PM XXCoder: yeah
05:29 PM Tom_L: pretty easy
05:29 PM Tom_L: datum same as construction lines?
05:29 PM XXCoder: yeah pretty easy. more complex than my usual though lol
05:30 PM XXCoder: https://imgur.com/yCzRqtx.png
05:30 PM XXCoder: need to add box on top then remove all excess
05:37 PM XXCoder: https://imgur.com/w3wWNHn.png all parts done
05:37 PM XXCoder: now to fuse em then cut it to size lol
05:45 PM Tom_L: you should try some of my practice drawings :)
05:45 PM XXCoder: ya
05:45 PM Tom_L: you saw some right?
05:46 PM XXCoder: think so? wasnt it at git?
05:46 PM Tom_L: no
05:46 PM Tom_L: the ones i did are on my site
05:47 PM XXCoder: ok got link :D
05:47 PM roycroft: i was struggling with solidworks this morning - trying to add features in sketches that are located by features in different sketches
05:48 PM Tom_L: i did that but don't remember what i did now
05:48 PM roycroft: i had to go run errands, and when i got home it dawned on me that it's trivial to add ancillary planes, and trivial to reference features off a plane
05:48 PM roycroft: it's going about 20x faster now
05:49 PM Tom_L: XXCoder, http://tom-itx.no-ip.biz:81/~webpage/cnc/practice_drawings/
05:49 PM XXCoder: oh different one yeah. saved link. thanks
05:49 PM roycroft: construction lines are a pain the butt to deal with, but planes are really easy, and quick
05:50 PM XXCoder: doh have to change design a little
05:50 PM XXCoder: it have sharp cutoff where I dont want it to have.
05:50 PM XXCoder: https://imgur.com/FuJaBnc.png
05:51 PM XXCoder: hose will snag on sides.
05:51 PM roycroft: but i also just realized that my brilliant unified carcase design doesn't quite work out
05:51 PM roycroft: so now i have to figure out what to do about that
05:51 PM XXCoder: top is alreadu adjusted to what I want
05:51 PM Tom_L: so add a blend to it
05:51 PM roycroft: it's about 1/8" too narrow for some of the components i need to install in the some of the carcases
05:51 PM Tom_L: roycroft, make it table driven
05:52 PM roycroft: that's really not the issue
05:52 PM Tom_L: then you can easily change the whole thing
05:52 PM roycroft: i'm making a bunch of carcases
05:52 PM Tom_L: you collect hotwheels?
05:52 PM roycroft: if make some at width x and some at width x+1/8, i'm going to get confused while cutting out and assembling
05:52 PM Tom_L: read that as car cases :)
05:52 PM roycroft: but that may be what i end up doing
05:53 PM roycroft: at least it's only two sizes, and not 3 or 4 similar sizes
05:53 PM roycroft: i was planning at first on taking my festool gear out of the systainers, and installing the molded systainer inserts in the drawers
05:54 PM roycroft: and then storing the empty systainers somewhere
05:54 PM roycroft: and that would work with the original design
05:54 PM roycroft: but then i went price shopping for materials
05:54 PM roycroft: most of the materials i need have at least doubled in price, and some have tripled in price
05:55 PM Tom_L: so have groceries
05:55 PM roycroft: so then i decided to just build skeleton frames for holding the systainers, and installing the systainers themselves
05:55 PM roycroft: to save on a *lot* of materials
05:55 PM roycroft: and that's where i ran into that 1/8" problem
05:55 PM roycroft: yeah, it's really not fun going anywhere these days to sohp
05:55 PM roycroft: shop
05:56 PM roycroft: on groceries i'm doing ok
05:56 PM roycroft: i've been buying fewer, and more simple foods
05:56 PM roycroft: my monthly grocery bill is pretty much unchanged from a couple years ago
05:56 PM roycroft: it's gone up maybe $30
05:57 PM roycroft: but i'm not buying the same stuff that i used to
05:57 PM roycroft: more generic brands, more non-organic
06:13 PM Tom_L: XXCoder, you gonna print that?
06:15 PM XXCoder: yeah though still fixing stuff
06:35 PM -!- #linuxcnc mode set to +v by ChanServ
06:45 PM XXCoder: Tom_L: nearly done lol
06:45 PM XXCoder: Tom_L: https://imgur.com/BKlD17f.png
06:46 PM XXCoder: adjusting so there is no edge but im close
06:47 PM Tom_L: edge where?
06:47 PM XXCoder: on both sides, arc is slightly too small so theres a step
06:47 PM XXCoder: slight adjust and arc meets block perfectly
06:50 PM XXCoder: aaand done https://imgur.com/gUvjZAS.png
06:51 PM XXCoder: more or less. need to add some radius to that edge
06:52 PM Tom_L: put it like it was and add a multi raidus blend to the edge
06:53 PM Tom_L: freecad probably doesn't do that
06:53 PM XXCoder: not sure too
07:03 PM XXCoder: Tom_L: https://imgur.com/MxMicJG.png
07:03 PM XXCoder: with big fillets for printability
07:22 PM roycroft: what is that part, xxcoder?
07:22 PM XXCoder: hose holder part
07:23 PM XXCoder: look at printable site url for older version
07:23 PM roycroft: oh, ok
07:23 PM roycroft: that makes sense
07:24 PM XXCoder: wow my objects getting complex. it lags a little now lol
07:38 PM roycroft: depth is also an issue if i insert the systainers and not just their inserts
07:38 PM roycroft: and that could get really expensive, as my current depth of the carcases is 24"
07:39 PM roycroft: i can get two pieces out of the width of a sheet of mdf, which is 49" wide
07:40 PM roycroft: maybe i'll have to add face frames to the carcases
07:43 PM XXCoder: wish me luck https://imgur.com/SWZEoV5.png
07:43 PM roycroft: the mail just came
07:43 PM Tom_L: any for me?
07:43 PM roycroft: my heat sensor for my 3d printer was allegedly out for delivery, but it did not show up
07:49 PM XXCoder: man you didnt get my gold brick delivery too?
08:23 PM roycroft: tom_l: i realise i never addressed your suggestion from earlier
08:23 PM roycroft: i am familiar with table driven dimensioning
08:24 PM roycroft: i do that frequently - the various sizes of hardware storage boxes, for example, would be a nightmare to draw without the width and length being table driven
08:24 PM roycroft: the problem is efficient use of materials
08:25 PM roycroft: i want to use at least 90% of each sheet of mdf or plywood that i cut up
08:26 PM roycroft: i did not make this project table driven, but i may to back and do that if i think i'm going to be making many adjustments
09:26 PM XXCoder: lol Tom_L rememebr that design? it works perfectly
09:26 PM XXCoder: however pins is too long to strongly hold on to holder. thankfully I designed a pin lock but never used it till now
09:27 PM roycroft: the tracking history for my 3d printer parts shows them out for delivery as of 6:42 this morning, and en route to the next facility as of 4:19pm today
09:31 PM Tom_L: roycroft, i think they're confused
09:34 PM roycroft: i've never seen them confused that badly before
09:34 PM roycroft: out for delivery never has anything following it except "delivered"
09:35 PM * roycroft thinks his temperature probe broke the postal service
09:39 PM solarwind: How do people hoist high pressure steel cylinders? Like your standard big T size argon cylinder?
09:39 PM solarwind: Every time I do it to load/unload off my welding cart, I do a big no no and hoist it by the cylinder cap
09:40 PM solarwind: It's not going more than 50cm off the ground, but still, I know it's not the right way
09:40 PM solarwind: I could make some kind of a frame for it with a proper lifting lug I gues
09:41 PM solarwind: But also contemplating some kind of "clamp" mechanism that grips the cylinder tightly like you're giving it a big hug
09:42 PM solarwind: Something lined with rubber from old automobile tires perhaps? I mean those things are designed for insanely high pressure, so I should be able to use a very high clamping force without getting anywhere near its stress limit
09:43 PM solarwind: Essentially something like this: https://www.cascorp.com/web2/home.nsf/files/3H_web.jpg/$FILE/3H_web.jpg
09:44 PM solarwind: I've been practicing TIG for _hours_ every day so I go through these cylinders very fast and they're heavy and not fun to move around
09:44 PM CloudEvil: I would look at the manufacturers datasheet for cylinders, and see if lifting by the collar is fine
09:44 PM roycroft: you can get lifting straps for cylinders
09:44 PM roycroft: webbed straps that wrap around the sides and the bottom
09:45 PM roycroft: i just use cylinders small enough that i can move around by myself
09:45 PM roycroft: but i don't go through a lot of gases
09:45 PM solarwind: wow can't believe I didn't think of searching for that first
09:45 PM solarwind: But now that I did, I LOVE this design: https://shutterlock.co.za/wp-content/uploads/2020/03/Gas-Cylinder-Lifter.png
09:46 PM solarwind: Need to make something for my Jeep that I can mount on the hitch to help me load it in and out of the back as well
10:46 PM XXCoder: sigh I screwed up
10:46 PM XXCoder: I thought pin locks didnt need any change
10:46 PM XXCoder: it did, since it sank in and I canbt get it out and remove the holder pins lol
10:46 PM XXCoder: locked for good I guess
