12:34 AM XXCoder: im making far more realistic endmill in vector art
01:18 AM randy: morning
01:29 AM Deejay: moin
01:37 AM xxcoder8265[m]: finally done
01:37 AM xxcoder8265[m]: https://media.discordapp.net/attachments/970073721291292702/973469500269817936/Discord_LinuxCnc_Chips_logo.png
01:38 AM XXCoder: its pure vector. also fixed right eye. always bothered me, as it was my worse work
04:50 AM Tom_L: morning
05:27 AM MrSunshine: oh what fun, do not get anywhere with the amb spindle so now the old hf spindle is on the machine again ... sigh :P
06:04 AM randy: MrSunshine: didi you machine alloy/aluminium with the AMB?
06:10 AM MrSunshine: randy, nope
06:10 AM MrSunshine: wood
06:14 AM randy: according to one video from KMS (https://www.youtube.com/c/KlausMichaelKMS) the dust could be an issue
06:14 AM JT-Cave: morning
06:14 AM randy: he had a broken AMB after alloy, send it to the vendor for repair, they told him a) no alloy b) use a dust cover for wood
06:14 AM randy: just for your info :)
06:15 AM MrSunshine: randy, probably .. as the wood dust seem to suck the grease out of bearings from meters away
06:16 AM MrSunshine: but im kinda mad at amb as they claim that the spindle is not disassembleable by me so i can change the bearings in MY UNIT ... im not about to be blackmailed into sending it in every time there is a problem with it
06:16 AM MrSunshine: i believe in repairing
06:21 AM randy: :)
06:23 AM MrSunshine: so get it apart, fix the parts that makes it hard to get apart ... fix the bearings and then i can change the bearings in the future without alot of hazzle ... problem is like stated before the get the rotor off the actual tool changer as i cant get a piece out that blocks the hole to push out the rotor ... catch 22 or whatever they call it :P
07:18 AM Tom_L: hi 97F
08:44 AM MrSunshine: hmm using JT-Cave's program to make the config i got a PID regulator for the spindle also, now that ive changed to the vfd again i have rs485 communication ... is there any simple way to convert the 7i92M pwm "code" to be sent to the vfd insted as commands ?
08:44 AM MrSunshine: i guess i get a 0 - 1 value from the pid ?
08:45 AM MrSunshine: in the mesa card there is min,max and scale to be input and i guess the mesa convertes the 0-1 to actual values dependant on those parameters
10:16 AM roguish[m]: MrSunshine: first question: doubtful. if you want to use RS485 you need to use something like a modbus comp. there are several, or you could write your own.
10:22 AM roguish[m]: MrSunshine: most important is to RTFM on Linuxcnc, and your VFD. Unfortunately it's not just click, click.............
10:23 AM MrSunshine: well im very aware of that, been using linuxcnc the last 10 years or so, also linux for the past 20 ... still its hard to navigate and an answer like RTFM is elitist and people who throws rtfm around them usaly doesnt know themselfs, so better to keep that kind of stuff to yourself
10:24 AM roguish[m]: ok, no offense meant.
10:29 AM MrSunshine: its ok, but i hate people who "rtfm:s" ive been at it for hours before i asked here trying to reasearch etc, the components in linuxcnc is hard to fllow in documentation and there is usaly some good example to look at that is alot easier to understand =) anyhow i did not need any scaling etc, just commented out the pid code and enterd some other and it works fine, reports the same on the vfd as i command so =)
10:29 AM JT-Cave: on my automation direct I use the gs2 comp for modbus
10:35 AM roycroft: telling people to rtfm is fine
10:35 AM roycroft: IF someone has written tfm decently :)
10:35 AM roycroft: sadly that is much less the case than it used to be
10:39 AM roycroft: so the weather forecast on the radio just said there is widespread frost throughout the valley, including here, and that there is a chance of hail an thunderstorms today
10:39 AM roycroft: it's 7 degrees at my house right now
10:39 AM roycroft: and the sun is shining
10:40 AM roycroft: the online forecast says it will be 16 degrees and sunny today
10:40 AM * roycroft is wondering where the radio station got their crack, because it seems to be the really good stoff
10:40 AM roycroft: stuff
10:47 AM MrSunshine: heh had problem with lost communication with the rs485 on the vfd as soon as i turned on the spindle .... aparently i hadnt connected the shield at the motor side .. did that and voila .. works great :P
11:01 AM coralgoat: JT-Shop, does <https://mesaus.com/product/7i78/> have a DB25 connector that is male or female?
11:01 AM coralgoat: I do not see it mentioned in <https://mesaus.com/product/7i78/>.
11:01 AM coralgoat: When I search <http://www.mesanet.com/pdf/parallel/7i78man.pdf> for male or female I get no results.
11:11 AM roycroft: afaik all the mesa db25 connectors are female
11:18 AM roycroft: if you're not 100% certain what your cable configuration is i would recommend buying one from mesaus - they're $10
11:18 AM roycroft: many db25 cables do not have all the pins wired through
11:26 AM unterhaus: I just found out I don't have my drivers license. Where did I buy beer last?
11:27 AM coralgoat: roycroft, thanks
11:37 AM t4nk_freenode: I thought I'd go 'fancy', and tap the holes for the anti-backlash nut into this mild steel
11:38 AM t4nk_freenode: .... m3 tap was a goner before I even got it to rest on the hole
11:38 AM t4nk_freenode: what a load of rubbish
11:40 AM roycroft: i had to tap for some m2.5 threads recently in mild steel
11:40 AM roycroft: i managed to succeed, but it seemed rather sketchy the whole time
11:44 AM roguish[m]: slow and easy. lots of TapMagic

11:44 AM Kennethfritz7780: Never got around to posting it in the irc but I completed two sweet 7i76e builds
11:44 AM Kennethfritz7780: Hopefully images make the bridge
11:45 AM roguish[m]: _discord_252539146164240384[m]: images are on Discord, but not here on Element (the Matrix)
11:49 AM joeyjoejoe0351[m: Dammn, nice setup!
11:50 AM joeyjoejoe0351[m: Love the enclosure. Was it repurposed from something else?
11:50 AM XXCoder: irc it shows as urls.
11:51 AM XXCoder: looks like standard electrics cabinet
11:52 AM joeyjoejoe0351[m: I gotta up my search-term game for these things "nema enclosure" isn't working out for any sweet deals.
12:06 PM Kennethfritz7780: Just standard nema enclosures, and thanks!
12:08 PM Thorhian7490[m]: Lol I wish decent enclosures didn't cost so much. The smaller 20" x 16" x 8" box I got was a major steal for $130, but it's still pretty small. Definitely wish it was bigger lol.
12:10 PM joeyjoejoe0351[m: The pricing is pretty crazy. I'm blown away by how much a bent and powder coated piece of sheet metal is but.. I guess the typical people buying an enclosure, 250$ is nothing when your electrician labor and BOM is going to be thousands of dollars.
12:10 PM joeyjoejoe0351[m: Err, probably 10's of thousands.
12:11 PM Thorhian7490[m]: Yeah... Plus you have certification, aka, knowledge that it should be resistant to what it has been rated to. You are on your own if you make it yourself too. Unfortunately I can't make such a box, I don't have the bending equipment to do it lol.
12:11 PM Thorhian7490[m]: s/too//
12:27 PM roycroft: when your product is forecast to sell in small numbers (thousands to a few tens of thousands) and you have to spend a few tens of thousands of dollars getting it ul certified, that adds a bit to the cost per unit
12:28 PM roycroft: talking about the enclosures themselves
12:28 PM XXCoder: I suppose can be done with powder gun and old oven (dont ruin your kitchen, you all)
12:32 PM Kennethfritz7780: https://media.discordapp.net/attachments/970073318810075149/973622356721434654/20210513_214626.jpg... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/9b4d9f00f588c1927dcc2233ed89be16c244d64a)
12:32 PM Kennethfritz7780: Links to those images
12:32 PM Kennethfritz7780: Not sure if they will work
12:32 PM roycroft: powder coating is nice, but i'm not set up to do it
12:33 PM roycroft: i usually shoot automative paint and clear coat on things i want to look nice
12:33 PM Kennethfritz7780: Just realized xxcoder said they show up as urla, doh
12:33 PM roycroft: if i had a larger shop i'd set myself up to powder coat
12:33 PM XXCoder: yeah you can just paste pictures in discord and it turns into urls for irc :D no work added needed
12:33 PM roycroft: or have jt make parts for me :)
12:34 PM XXCoder: though yeah if message is too long it turns into text link. it had list of urls lol
12:45 PM joeyjoejoe0351[m: Absolutely - UL certification isn't free.
12:45 PM joeyjoejoe0351[m: Cost of doing business.. it just sucks as a hobbyist as I guess there's not many cheap alternatives. Used, or possibly plastic enclosures
12:46 PM Thorhian7490[m]: Lol I saw a 30" x 30" x 10" enclosure for under $100 on ebay one time used. Problem was that you had to pay for freight shipping (and that was just too big lol).
12:56 PM unterhaus: salsa spill on keyboard, bad news
12:57 PM unterhaus: fortunately didn't get to the enter key, that would have been bad
12:58 PM Tom_L: i spilled juice on one a while back and took several switches apart and cleaned them
12:59 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Omnikey_key/alps3.jpg
01:03 PM Thorhian7490[m]: Is that an alps switch?
01:03 PM Tom_L: yes
01:04 PM Tom_L: from an old omnikey kbd
01:13 PM unterhaus: cheap mechanical keyboard. I might run it through the dishwasher if just rinsing it off didn't work
01:25 PM joeyjoejoe0351[m: I'm eyeing one now, 16x12x7.. 125$, i'll see what freight costs.
01:27 PM Tom_L: kinda small
01:33 PM joeyjoejoe0351[m: I know. It's not ideal but might be enough to play around. I have small stepper drivers and a single mesa... I guess PSU's might make it tight.
01:45 PM XXCoder: roycroft: check this out https://imgur.com/a/QCsaRdC
01:45 PM XXCoder: interesting project idea
02:14 PM roguish[m]: _discord_305515215540191232[m]: I used one of these https://www.amazon.com/gp/product/B073RJNDSW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
02:21 PM joeyjoejoe0351[m: That's awesome, great tip. Way more space. More then enough for hobby use. Can throw the PC in there too!
02:27 PM CaptHindsight[m]: roguish[m]: what gauge is the metal for that cabinet?
02:29 PM roguish[m]: not sure. but it works good. I put an aluminum back panel inside. definitely not ideal, but completely adequate for my hobby machine.
02:30 PM MrSunshine: https://www.youtube.com/watch?v=VzRzdK6RjvY hmm maybe should get a new nose nut machined for the hf spindle, with setscrew holes .. this is brilliant =)
02:30 PM roguish[m]: i looked for an enclosure for some time. ebay, craigslist, facebook market, all over......
02:32 PM CaptHindsight[m]: https://www.menards.com/main/storage-organization/garage-outdoor-storage/garage-cabinet-systems/masterforce-reg-30-1-2w-x-30h-x-12-3-8d-2-door-wall-garage-storage-cabinet/f30142wc/p-1464215347913-c-12653.htm this one is about the same size but 75 lbs
02:34 PM CaptHindsight[m]: used metal cabinets are like gold around here, everybody wants them
02:35 PM Kennethfritz7780: Most of the machines I see in the diy category have a cheap Chinese vfd (two of my machines do) and I've learned the hard way that the emi from them is bonkers
02:36 PM Kennethfritz7780: And even if you properly ground and shield everything, you just can't put that vfd in the same enclosure with the controller and have a reliable setup
02:36 PM CaptHindsight[m]: EMI reducing components may be removed to save costs without most people noticing
02:36 PM Kennethfritz7780: The best bet is to have both in their own properly grounded enclosure but that may not be realistic for everyone
02:37 PM Kennethfritz7780: My very first enclosure was laser cut acrylic and it worked except when the vfd operated at a few specific frequencies and then it wreaked havoc
02:38 PM * Kennethfritz7780 uploaded an image: (3808KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/QIIfRXsfmtZedGUEvSdjApfe/20210324_172036.jpg >
02:38 PM Kennethfritz7780: By the end it wasuch too cramped in there for airflow too
02:38 PM CaptHindsight[m]: plan your cabinet space and then double :)
02:39 PM roycroft: fortunately my controller cabinet for my router is too small to house the vfd
02:41 PM roycroft: how often do those lower two gecko drives overheat in that "enclosure", kennethfritz7780?
02:42 PM * roycroft is now officially a full day behind on his project, but making forward progress again
02:47 PM XXCoder: hmm not sure which forum section is best to post my new mascot Chip svg file
02:49 PM XXCoder: also, did you see my earlier link roy?
02:53 PM CaptHindsight[m]: XXCoder: maybe Other Stuff
02:53 PM XXCoder: ok
02:53 PM XXCoder: I redid the svg I had modified few years afo
02:53 PM XXCoder: eyes is better
02:54 PM XXCoder: endmill is remade, and way better
02:55 PM XXCoder: https://images-ext-1.discordapp.net/external/5226Tq6b9pZ98mQLFGaUN2e4pVj2R1hy9v_uPKBaeZc/https/media.discordapp.net/attachments/970073721291292702/973469500269817936/Discord_LinuxCnc_Chips_logo.png
02:56 PM XXCoder: hold on
02:56 PM XXCoder: https://media.discordapp.net/attachments/970073721291292702/973469500269817936/Discord_LinuxCnc_Chips_logo.png
03:09 PM CaptHindsight[m]: can you make the endmill a name brand?
03:09 PM XXCoder: I suppose, but I dont see why at all, since its for linuxcnc not for endmill
03:10 PM CaptHindsight[m]: we should make a 3d model so it may be machined or printed
03:10 PM CaptHindsight[m]: and 3d animated
03:11 PM XXCoder: I suppose but i'm not great on turning 2d stuff into 3d :D
03:11 PM CaptHindsight[m]: I can take a look when i get time
03:13 PM CaptHindsight[m]: maybe 7 pieces
03:14 PM roycroft: and my problem is that i'm not good turning 3d into 2d (as far as modeling and drawings goes)
03:14 PM CaptHindsight[m]: wings, feet, head made to move
03:14 PM * roycroft is again making cut sheets using autocad, because he still has not figured out the weirdnesses of sw drawings
03:14 PM CaptHindsight[m]: the better tools automate that for you
03:15 PM CaptHindsight[m]: SW does that
03:15 PM CaptHindsight[m]: oh maybe a Mr Potato head version
03:16 PM CaptHindsight[m]: with different tools
03:17 PM Tom_L: roycroft, export an iges then take a layer off for the 2d
03:18 PM Tom_L: and XXCoder import a dxf and just give it some thickness and you have 3d
03:18 PM roycroft: i can save a part or assembly as a drawing just fine, but the problem is editing the drawing
03:19 PM roycroft: i just need to spend some more time with it, i'm sure
03:19 PM roycroft: but i don't have that time right now
03:19 PM roycroft: i'm in the middle of a project build that i modeled in 3d
03:19 PM roycroft: and need 2d drawings to make the parts
03:20 PM Tom_L: sheet metal?
03:20 PM CaptHindsight[m]: editing an imported 2D in SW is a bit odd
03:20 PM Tom_L: other than that i see 3d
03:21 PM CaptHindsight[m]: you need the magic import settings
03:21 PM Tom_L: my cad doesn't export very well though. that's the only real drawback to it
03:21 PM Tom_L: it's so old
03:22 PM CaptHindsight[m]: modify drawing vs modify part
03:22 PM Tom_L: i can manage to import most things
03:22 PM Tom_L: and my older iges import tool works better than the new one
03:23 PM Tom_L: the new one tries to make polylines out of everything
03:23 PM CaptHindsight[m]: I'm mucking with QEMU + KVM with GPU pass through with Linux host of Win11
03:24 PM Tom_L: that sounds like it could be a cluster fck
03:24 PM CaptHindsight[m]: getting closer, the docs are terrible, so I actually did some win11 installs for now on bare metal
03:25 PM CaptHindsight[m]: it's known to work but nobody has bothered to write good docs, so as usual just plow through, waste your time and finally get it working, then you're so sick of it you don't write the docs either :)
03:25 PM Tom_L: 93F
03:26 PM roycroft: and now i'm enjoying the spinning blue circle of quality on my cad workstation
03:27 PM Tom_L: better than the blue screen of death
03:27 PM roycroft: because i have to get back to the shop and break down a bunch of panels while the weather is still nice
03:27 PM CaptHindsight[m]: the GPU pass-through is the part that takes some work, VM's with win on Linux host only take a few minutes to config and build
03:27 PM CaptHindsight[m]: yeah 90F here
03:28 PM CaptHindsight[m]: I was out the other night in frost
03:28 PM roycroft: oh, i see
03:28 PM roycroft: when i convert a part to a drawing it wants to autodimension
03:28 PM roycroft: and i'm doing the side panels for my cabinets now
03:28 PM roycroft: which have a grid of 5mm holes spaced every 32mm apart for attaching drawer slides and the like
03:29 PM roycroft: it decided to generate dimensions for each hole
03:29 PM roycroft: which i now have to figure out how to remove
03:29 PM Tom_L: you can probably turn that off
03:29 PM CaptHindsight[m]: heh and boy oh boy, does it dimension everything
03:29 PM CaptHindsight[m]: yeah you can supress
03:30 PM CaptHindsight[m]: drawings with more dimensions than actual drawing
03:33 PM roycroft: i'm sure i can, tom_l
03:33 PM roycroft: that's part of the stuff i haven't figured out yet
03:33 PM roycroft: and not only did i never really learn how to deal with sw drawings, this new version behaves a lot differently to the old version that i learned on and used for years
03:34 PM Tom_L: yeah things have come a long ways
03:34 PM roycroft: a lot of behaviors are different - i don't know if they changed some defaults, or if i customized things years ago and forgot that i did so
03:34 PM roycroft: more likely the latter
03:34 PM CaptHindsight[m]: I found a backup of my drives from the 80's
03:35 PM Tom_L: but do you still have the equipment to restore it?
03:35 PM CaptHindsight[m]: I checked the size of the folder and it was 250MB, uncompressed
03:36 PM CaptHindsight[m]: when 1GB drives were >$2k
03:36 PM CaptHindsight[m]: I transfer backups every few years
03:37 PM CaptHindsight[m]: applications written in Basic
03:39 PM CaptHindsight[m]: hah 1983 DOS 2
03:39 PM Tom_L: i may have one of those
03:40 PM Tom_L: i had dos on a 5.25 but finally got rid of those
03:40 PM Tom_L: may have been dos 1.xx
03:40 PM CaptHindsight[m]: "First version to support 5.25-inch, 180 KB and 360 KB floppy disks"
03:42 PM CaptHindsight[m]: I used Mac's for work, CAD, Office etc and PC's for controllers
03:43 PM CaptHindsight[m]: what would you go back and tell yourself 40 years ago?
03:45 PM Tom_L: https://www.youtube.com/watch?v=pVQeP5vRP5E
03:45 PM Tom_L: wear sunscreen?
03:46 PM Tom_L: keep your hotrod, it'll be worth $$$ in 40 yrs
03:46 PM Tom_L: unless of course you wrapped it around a pole
03:47 PM CaptHindsight[m]: Apple or MS stock?
03:47 PM XXCoder: $$$ - 40 years of storage and maintance
03:47 PM CaptHindsight[m]: "don't worry, things only get worse"
03:47 PM Tom_L: forest gump bought apple stock
03:48 PM CaptHindsight[m]: some tech gets better
03:48 PM XXCoder: there was supposed to be sequel for that movie. they dropped it
03:48 PM CaptHindsight[m]: Gump II, electric boogaloo?
03:49 PM CaptHindsight[m]: Gump vs Predator?
03:50 PM CaptHindsight[m]: XXCoder: they killed off Jenny, would they have focused on his son?
03:51 PM CaptHindsight[m]: or Gump moves into an apartment with 8 other people and they film them 24/7 and nobody notices that he is the supposed mentally challenged one
03:52 PM XXCoder: nah supposed to be similiar to first, he goes though conences that improve his life
03:53 PM JT-Shop: Bonnie pint size plants $5, Hillis nursery $1 per container which has 4 plants or 2 plants depending on their size
03:56 PM Kennethfritz7780: They never overheated but I got mighty toasty for sure
03:56 PM Kennethfritz7780: The gecko guys actually sent me a t shirt when I uploaded the rebuild
03:56 PM Kennethfritz7780: Was super surprised
03:57 PM Tom_L: all i got was a key chain
03:57 PM JT-Shop: I got a gecko
03:58 PM * JT-Shop keeps looking at the chainsaw but it doesn't clean and sharpen itself
03:59 PM Kennethfritz7780: I've built four machines with gecko drives now, I'm pretty pleased with them. I probably should have opted for servos on the last two though
03:59 PM CaptHindsight[m]: Kenneth fritz#7780: why? What type of machines are the last two?
04:00 PM CaptHindsight[m]: I have been pleased by the newer closed loop stepper motors IF the machine doesn't have to be too fast
04:01 PM CaptHindsight[m]: surprisingly quiet for steppers
04:02 PM Kennethfritz7780: Little routers
04:03 PM JT-Shop: CaptHindsight[m], where did you get the closed loop steppers?
04:04 PM * Kennethfritz7780 uploaded an image: (7892KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/XINDCCSrJePyyouPpkWZfzKv/20210602_201154.jpg >
04:04 PM XXCoder: interesting. 4040 framing?
04:04 PM CaptHindsight[m]: JT-Shop: Amamzon, let me find the link, thiy have drivers in the motor
04:05 PM Kennethfritz7780: Mixture of stuff mostly cbeam
04:05 PM XXCoder: cool
04:05 PM CaptHindsight[m]: https://www.amazon.com/Stepper-Integrate-Position-Encoder-Control/dp/B01MFA87KI/ref=sr_1_19
04:06 PM CaptHindsight[m]: the only thing from China in recent history that was actually good
04:06 PM XXCoder: nice! bit expensive for me sadly lol
04:06 PM Tom_L: surprised they don't use nema17 on lasers
04:06 PM Kennethfritz7780: Automation direct has some reasonable options too
04:06 PM XXCoder: tom it needs speed and I thinbk nema17 is too weak to do a quick turnaround
04:07 PM Kennethfritz7780: Still more than that though
04:07 PM CaptHindsight[m]: Kenneth fritz#7780: Parker for the Y and Z?
04:07 PM XXCoder: capt thing on top is stepper driver?
04:07 PM XXCoder: so basically all I need is signal to command it, and power source?
04:07 PM Kennethfritz7780: Yeah, my axyz and shopsabre move so fast that I barely ever use the little machines for anything but prototyping
04:08 PM Kennethfritz7780: I actually don't recall which motors I used on that one
04:08 PM Kennethfritz7780: I use the same connectors for ally steppers, swap around a lot
04:09 PM CaptHindsight[m]: https://i.imgur.com/bO3oIC9.jpg with parker servos and positioners
04:09 PM XXCoder: interesting. looks kinds like mill type bottom buyt cant tell what top is
04:10 PM JT-Shop: CaptHindsight[m], is the drive on the side of the stepper?
04:11 PM CaptHindsight[m]: JT-Shop: yes, screwed onto the the back
04:11 PM JT-Shop: what does all the I/O do?
04:12 PM CaptHindsight[m]: different versions have Step/Dir or RS422
04:12 PM CaptHindsight[m]: or CAN
04:12 PM JT-Shop: ah
04:13 PM CaptHindsight[m]: https://m.media-amazon.com/images/I/61RI1sHZXnL._AC_SL1000_.jpg
04:14 PM CaptHindsight[m]: i used them on a positioner with a really fine pitch, 1mm
04:16 PM CaptHindsight[m]: 1k ppr = 1um, but with all the variances and over temp is more than good enough for +/- 5um
04:18 PM JT-Shop: nice
04:19 PM CaptHindsight[m]: 150mm travel on a Z
04:23 PM JT-Shop: would those make a small router table say 24" x 24"?
04:29 PM CaptHindsight[m]: I'd use them for that
04:31 PM CaptHindsight[m]: I still have to try the RS422 versions
04:31 PM CaptHindsight[m]: sorry RS485
04:33 PM JT-Shop: I don't see any options or different sizes on amazon
04:34 PM CaptHindsight[m]: JT-Shop: new https://www.automationdirect.com/adc/overview/catalog/motion_control/stepper_systems/integrated_stepper_motors_-z-_drives
04:35 PM CaptHindsight[m]: but 2x the price :(
04:35 PM JT-Shop: yep I was looking at them the other day
04:36 PM JT-Shop: only 24v too
04:36 PM CaptHindsight[m]: some of the stepper drives there are half the price they we a few years ago
04:36 PM JT-Shop: hmm they do have 48v but not in the selector
04:36 PM * JT-Shop is a frequent shopper at AD
04:37 PM CaptHindsight[m]: yes, i recall
04:38 PM CaptHindsight[m]: oh these have come down in price https://www.omc-stepperonline.com/closed-loop-stepper-motor?mfp=184-frame-size-mm[Nema%2023%20(57%20x%2057)]
04:39 PM CaptHindsight[m]: https://www.omc-stepperonline.com/isc-isd integrated drive version
04:39 PM XXCoder: wow thats very long nema8
04:40 PM JT-Shop: looks like most ship from china at stepperonline
04:41 PM JT-Shop: AD mid line integrated stepper has encoder output...
04:41 PM * JT-Shop goes to spoil the chickens
04:42 PM XXCoder: spoiled chickens no good to eat
04:42 PM XXCoder: ;)
04:50 PM * JT-Shop sees only one chainsaw left to clean, sharpen and service...

05:05 PM JT-Shop: alaskan sawmill I used on the giant red oak
05:05 PM JT-Shop: 48" bar on the 391 was a good workout for sure
05:06 PM Tom_L: https://www.stihlusa.com/webcontent/cmsfilelibrary/instructionmanuals/stihl020t_with_safety_manual.pdf
05:06 PM Tom_L: i've got the pole and the 020T for climbing
05:06 PM Tom_L: very well balanced
05:08 PM JT-Shop: that's a cool saw, ebay has one for $1,499.99
05:08 PM Tom_L: i certainly didn't pay that for it new
05:08 PM Tom_L: it's a 1 hander for climbing
05:08 PM JT-Shop: https://www.ebay.com/itm/325174777143?hash=item4bb5ed5537:g:nbUAAOSwkMhicbxX
05:09 PM roguish[m]: the Giro d'Italia bike race went up Mt Etan today. big hill
05:09 PM Tom_L: 10" bar iirc
05:12 PM JT-Shop: the pole saw has a 10" or 12" bar I forget
05:12 PM Tom_L: yeah i can't remember either but i think it's 10
05:13 PM Tom_L: probably interchanges with the hand saw
05:13 PM Tom_L: or i'd have more blades
05:13 PM Tom_L: then the old brute mac
05:13 PM Tom_L: probably as old as me
05:15 PM JT-Shop: I needed a big mac with that alaskan sawmill it was all the 391 could do on a 48" bar
05:16 PM Tom_L: that's a handfull on anything
05:18 PM Tom_L: i got it out last summer just to see if it would start
05:18 PM Tom_L: fired right up
05:18 PM Tom_L: i figured i'd have to clean the carb etc but no..
05:20 PM JT-Shop: nice, what size power head is it?
05:34 PM roguish[m]: check this out. I worked on its start about 9 years ago...... https://www.engadget.com/slacs-newest-laser-accelerator-is-colder-than-space-200010659.html
05:34 PM roguish[m]: a very fancy strobe light.
05:34 PM roguish[m]: femtosecond light pulses.
05:43 PM Tom_L: i'm not sure
05:43 PM Tom_L: i don't think it's a huge one
05:50 PM Nkt[m]: Real Genius was right!
05:51 PM Tom_L: might be a 1010 http://www.acresinternet.com/cscc.nsf/ed1d619968136da688256af40002b8f7/e134c94c3ee94a6488256c2e007315a7
05:53 PM JT-Shop: same size as my MS 291
06:04 PM Tom_L: i bet it's noisier :)
06:10 PM JT-Shop: yours"
06:10 PM JT-Shop: ?
06:11 PM Tom_L: yeah, not much of a muffler on those things
06:25 PM * JT-Shop just put the Spyder up for sale
06:29 PM Tom_L: :/
06:29 PM Tom_L: haven't been riding it much lately?
06:31 PM JT-Shop: wife has trouble getting on and has problems with her back
06:31 PM JT-Shop: so yep not riding it much last few years
06:32 PM JT-Shop: going to get a Polaris Slingshot
06:33 PM Tom_L: easier to get in and out of?
06:34 PM JT-Shop: https://slingshot.polaris.com/en-us/build-color/?transmission=Manual&CatalogContentId=672220__CatalogContent

06:39 PM Tom_L: you know how much trouble you had finding a home for the honda...
06:40 PM JT-Shop: yep, been thinking of pouring a slab under the carport and enclosing it
06:42 PM Tom_L: you may as well not. instead clear some more space for yet another 50 x 200 or so shop
06:42 PM Tom_L: i'm sure you won't have a problem filling it
06:42 PM Tom_L: :)
06:42 PM JT-Shop: I don't have that much flat ground lol except down in the lower flat area
06:43 PM JT-Shop: I can put a 24' x 24' on the south end of the garage
06:43 PM Tom_L: maybe ok for some offload..
06:43 PM JT-Shop: slingshot and bluewing and firewodd
06:44 PM JT-Shop: prob take a long time to get it lol
06:48 PM Tom_L: no doubt
06:48 PM roycroft: *whew*
06:49 PM roycroft: i'm done breaking down the melamine panels
06:49 PM * JT-Shop wanders inside
06:49 PM roycroft: those things are bloody heavy!
07:05 PM XXCoder: JT-Shop: $1000. for me to come pick it up lol
07:33 PM sliptonicBradCol: Anyone here do commercial work? Looking for someone to quote some parts. Probably Swiss lathe work. Not terribly high accuracy. I've tried to find local places to do the work but apparently I use the wrong words to get their attention.
07:38 PM Tom_L: what volume?
07:39 PM Tom_L: that will affect how they answer you
07:40 PM Tom_L: manual or cnc?
07:40 PM XXCoder: since swiss lathe is menioned, its likely cnc lathe, one with ability to switch sides
08:05 PM mrec: today is lathe day
08:06 PM mrec: maybe time to extend G71 in linuxcnc the leadin is still too quick for steel
08:08 PM roycroft: well this sucks
08:08 PM roycroft: the melamine edge banding i got is 0.474" wide
08:09 PM roycroft: i've never seen edge banding that narrow
08:09 PM roycroft: standard melamine with both sides coated is substrate thickness +0.020", so 0.477"
08:09 PM Tom_L: and you needed 1/2"?
08:09 PM roycroft: for what i got
08:10 PM roycroft: sorry, i meant 0.744" and 0.770"
08:10 PM roycroft: i'm really tired
08:10 PM Tom_L: meh what's .030ish among friends?
08:10 PM roycroft: the "narrow" edge banding that i usually get is 0.8125" wide, and the wide stuff, which is what i usually get, is 0.875" wide
08:11 PM roycroft: i like the wide stuff because my edge bander is not terribly accurate
08:11 PM Tom_L: better save it for another project and get some more
08:11 PM roycroft: but this crap i have now is so narrow i can't even iron it on and cover the entire edge
08:11 PM roycroft: i'll never used it
08:11 PM roycroft: it's going back
08:11 PM roycroft: the problem is, if i were on schedule i need it today
08:11 PM roycroft: i'm behind schedule, but i need it tomorrow
08:11 PM roycroft: and i don't know of a local source
08:11 PM XXCoder: sucks
08:12 PM roycroft: if i order it, even overnight, it won't get here until thursday
08:13 PM roycroft: i don't even know why they make the stuf
08:13 PM roycroft: it's totally useless
08:13 PM roycroft: it is way to wide for 1/2" panels
08:13 PM roycroft: even a bit too wide for 5/8" panels, which are rare
08:13 PM roycroft: anyway, i have a board meeting in a couple minutes
08:13 PM roycroft: the edges that will be covered with the melamine banding will be totally hidden
08:14 PM roycroft: i may end up having to just suck it up and use this stuff and figure out how to seal the exposed parts of the edges
08:14 PM roycroft: i'm using it more to seal the wood than for appearance - i don't want the particle board substrate to swell up over the years
08:42 PM xxcoder8265[m]: lol. https://www.reddit.com/r/Machinists/comments/umxqz4/when_you_eat_chips_after_work_lol/
08:42 PM XXCoder: cant just seal it before putting it in?
10:00 PM _unreal_: so I just got a summit series 48v eazy go battery charger. what I dont like is its switching. I'm wondering how hard it might be to turn it into a psu
10:00 PM _unreal_: right now its a lead acid charger
10:01 PM Tom_L: 13.xx v?
10:02 PM _unreal_: 48v 13.5A
10:02 PM Tom_L: mmm
10:02 PM _unreal_: it also has blue tooth monitoring interface as well which I dont like....
10:02 PM Tom_L: mine is 13ish v iirc
10:02 PM _unreal_: i'm just looking at it as a PSU
10:03 PM Tom_L: ya 13.4v 45A
10:03 PM _unreal_: 48v
10:03 PM _unreal_: herhe
10:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/12v_supply3.jpg
10:04 PM _unreal_: I'm just wondering how hard it will be to convert it to a psu
10:04 PM _unreal_: I assume the main goal is just to "bypass" the charge sense
10:04 PM flyback: nice psu
10:05 PM _unreal_: batterypete.com/Lester-summit-ii-series-battery-charger-bluetooth-wireless-app-diagnostics/
10:05 PM Tom_L: charger
10:06 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/12v_supply2.jpg
10:08 PM _unreal_: and what do you use that for?
10:09 PM Tom_L: nothing
10:09 PM Tom_L: it was off some large rv
10:10 PM Tom_L: upgraded. kinda like the stuff you get
10:10 PM _unreal_: ok so its a house battery bank charger then
10:10 PM _unreal_: for RV
10:10 PM Tom_L: yeah
10:10 PM _unreal_: likely for a 4-8 parallel cell setup
10:10 PM Tom_L: no idea
10:11 PM _unreal_: this charger is for 6 batteries in series
10:11 PM _unreal_: bu like I said I'm wondering how hard it could be to bypass the battery sense and just turn it into a PSU
10:14 PM XXCoder: finally posted new svg and picture example https://forum.linuxcnc.org/show-your-stuff/32672-linuxcnc-logo?start=30#242559
10:15 PM XXCoder: CaptHindsight[m]: thanks
10:51 PM roycroft: ooh
10:51 PM roycroft: my local woodcraft store allegedly have 7/8" melamine edge banding in stock
10:51 PM * roycroft will make an excursion in the morning
10:52 PM roycroft: and they open at 9 now
10:52 PM roycroft: they had been opening at 11 during the pandemic
10:52 PM XXCoder: yay
10:52 PM roycroft: yeah, if the actually have it my problem is solved
10:56 PM roycroft: unfortunately, the ash edge banding, which is plenty wide, has to be applied last
10:57 PM roycroft: and i can't even cut the panels to final size until i have the edge banding, because i have to apply it to a test piece to measure how much thickness it adds
11:23 PM snakedGT is now known as snaked
