12:20 AM Vvega[m]: Howdy !!
12:29 AM XXCoder: hi
12:29 AM Vvega[m]: I’ve come looking for people that know a bit about Linux cnc 🙂
12:35 AM roycroft: well that was an interesting show
12:35 AM roycroft: i've learned that for me, weird al is best taking in small doses
12:36 AM XXCoder: lol
12:36 AM roycroft: i did enjoy the show
12:36 AM roycroft: but he was doing his most obscure songs
12:36 AM roycroft: i did not recognize a single song he did until the encore
12:37 AM roycroft: and i've been listening to him for decades
12:37 AM roycroft: but i don't think i have a single one of his albums
12:38 AM roycroft: what was really interesting is that there were way too many really nerdy people there who knew every one of those obscure songs by heart and were way way way too enthusiastic about the show
12:38 AM XXCoder: thats nerd people in anything
12:38 AM roycroft: anyway, i'm back
12:39 AM XXCoder: welcome back
12:39 AM roycroft: and the first thing i did was go out into the shop
12:39 AM roycroft: that systainer tray i glued up before the concert was ready to come out of the clamps
12:39 AM roycroft: i had to do a test fit - there was no way to know for sure if it would fit until after it was glued up
12:40 AM roycroft: and those drawer slides are not very forgiving - width has to be about +0/-1mm or they won't work
12:40 AM roycroft: fortunately, it fits :)
12:41 AM roycroft: especially because it takes several setups on the router table to cut the dovetails and slots in the tray fronts, so i machined all of them at the same time, before i had done a test fit
12:43 AM XXCoder: nice work
12:43 AM roycroft: thanks
12:44 AM roycroft: it's a relief more than anything
12:55 AM roycroft: i'm also out of black filament now
12:56 AM XXCoder: aw
01:09 AM Deejay: moin

03:00 AM CaptHindsight[m]: whats in dah box?
03:01 AM Rhine_Labs: 100W https://www.stevenrhine.com/wp-content/uploads/2022/06/20220630_185139-1024x576.jpg
03:01 AM Rhine_Labs: Co2
03:02 AM CaptHindsight[m]: good deal?
03:02 AM Rhine_Labs: Yep.
03:04 AM Rhine_Labs: Little use on it has a leetro mpc6535 controller just ordered expedited a Ruida RDC6445 that way can use lightburn on the Fiber and co2
03:05 AM Rhine_Labs: I am stll up 1am lol gave to have trailer back by 7am
04:06 AM travis_farmer: G'Morning

08:42 AM jdh: flywheel?
08:43 AM skunkworks: start of a chuck backplate for an emco compact 5 lathe
09:44 AM JoseIgnacioRomer: Fancy flywheel
09:49 AM Gamad[m]: .
09:49 AM Gamad[m]: Hello
09:50 AM Gamad[m]: Does anyone here use PoKeys ethernet control board?
10:26 AM firephoto__ is now known as firephoto_
10:44 AM skunkworks: Gamad[m]: I think there are some threads on the forum?
10:49 AM pere: So, my CNC got as far as giving me a "joint 0 following error" message when I try to enable the X axis. :)
10:53 AM Tom_L: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Following_Error
10:53 AM pere: thanks. had just started reading the forums.
10:55 AM pere: ah, wiki.linuxcnc.org also block us that do not want to be tracked, similar to linuxcnc.org. :(
10:57 AM Tom_L: LinuxCNC checks to see whether the commanded position is within range of the actual position. If this error is out of range, you get an error message something like:
10:57 AM Tom_L: the error you got
10:57 AM Tom_L: The LinuxCNC ini file uses two variables, FERROR and MIN_FERROR to define acceptable following error for each axis
11:01 AM pere: I suspect all these values are out of wack as seb_kuzminsky did some simplifications while we test other parts.
11:04 AM Tom_L: http://linuxcnc.org/docs/stable/html/config/ini-config.html#_joint__lt_num_gt_section
11:06 AM roycroft: pere: you can use tor browser and remain pretty anonymous
11:06 AM roycroft: gst3d still are not responsing about their defective product
11:07 AM pere: roycroft: not when linuxcnc.org block access for tor users.
11:07 AM roycroft: we'll see how they respond to the dispute i just filed with my cc issuer
11:07 AM roycroft: oh, i did not know they block tor user access
11:07 AM roycroft: i'll have a chat with management about that :)
11:08 AM roycroft: you could always use a vpn and a private browser window
11:43 AM travis_farmer: in an "o sub", using a "o if", what do i test to see if the machine is in inch or mm mode?
11:45 AM Tom_L: you can set it with G20 G21
11:45 AM Tom_L: dunno about testing it
11:46 AM travis_farmer: right, but if i am inch/mm, i can switch to what my "o sub" needs, then i need to know what it was set to before, so i can set it back if needed
11:49 AM roycroft: perhaps you should standardize on one unit system or the other and always use the same one?
11:49 AM roycroft: that would eliminate any mars mission errors
11:50 AM travis_farmer: Hmmm, true, i will do that. i just wanted to sorta prepare for somebody sending mm gcode, when my machine is set in inch. but yeah, K.I.S.S. would be better ;)
11:51 AM Tom_L: have 2 configs if you need to
12:01 PM travis_farmer: these are sheet alignment subroutines that probe for the angle, based on JT's examples. it would use up too many macro buttons on my pendant to have for both.
12:09 PM travis_farmer: found it:
12:09 PM travis_farmer: #<_metric> - Return 1 if G21 is on, else 0.
12:09 PM travis_farmer: #<_imperial> - Return 1 if G20 is on, else 0.
12:16 PM MikeM[m]: Good afternoon
12:17 PM MikeM[m]: Several weeks ago several of you gave some advice on what was my very messy wired controller (basically wires ever where all out in the open on a piece of plywood).
12:17 PM MikeM[m]: And an issue I was having as a result is if other machines in the shop powered up, the CNC would skip steps, and was very consistent at doing so.
12:19 PM MikeM[m]: Well, I built my enclosure, which is all wood, which isn't that great of an insulator from interference, but I did take the advice of using shielded wires to and from the stepper drivers and also made sure signal wires were away from power supply wires as much as possible. The result with everything enclosed, no more skipped steps!!
12:20 PM MikeM[m]: I ran a test today where I powered up and down several machines and tools and the CNC never missed a beat, when previously it would always do it.
12:20 PM MikeM[m]: So thank you guys for the very excellent advice!!
12:21 PM travis_farmer: Glad i could help (i had nothing to do with it... ;) )
12:25 PM MikeM[m]: LOL
12:26 PM MikeM[m]: It has definitely been an enjoyable journey building my CNC, and feels even better when getting items on my punch-list of fixes taken care of. The enclosure and the skipping steps from interference was a big one.
12:29 PM travis_farmer: not sure if it is nesisary, but i used conductive copper foil, with a sticky back to help shield my enclosure. just the back-board, as i was intending on building a full wood enclosure, but ended up with a metal one anyway. but maybe you could line your enclosure with some of that, if you can get a hold of some. just for extra protection.
12:30 PM roycroft: that's what i'm planning on doing for my cnc router
12:30 PM roycroft: i have a nice electrical box that i was doing to use to mount the electonics, but it's not quite big enough
12:30 PM Tom_L: alum duct tape would work too
12:30 PM travis_farmer: copper looks pretty though ;) lol
12:30 PM roycroft: so i'll just build a compartment into the machine base to hold the cnc electronics, and line it with copper foil
12:30 PM Tom_L: just messy if you ever have to fix anything
12:31 PM roycroft: i'll be able to easily ventilate that compartment anyway, something that would be a bit more difficult with the metal box
12:31 PM Loetmichel: well, copper foil only helps if its REALLY a farady cage
12:32 PM Loetmichel: and dont forget the wires to the machine. shielded works a lot better
12:32 PM travis_farmer: "farady cage" was my plan, but i went all metal enclosure anyway. it does have to be grounded
12:32 PM roycroft: if i don't have any major constuction work to do on our fair booth this weekend i hope to begin reviewing my cad drawings for the router, and perhaps even continue work on that project
12:37 PM MikeM[m]: Yeah, grounding, from what I have learned, is probably one of the most important pieces to having the electronics work well.
12:37 PM roycroft: solid copper lining would actually be called a faraday shield, not a faraday cage
12:37 PM travis_farmer: true, roycroft...
12:38 PM roycroft: and ground the shielded cables at one end oly
12:38 PM roycroft: only
12:38 PM roycroft: er
12:38 PM roycroft: ground the cable shield at one end only
12:40 PM roycroft: a cable shield is a form of faraday cage or faraday shield, depending on whether it's made of woven wire or metal foil
12:41 PM travis_farmer: i was tempted to get one of those EMF/EMP meters and see what escapes my shielding... never got around to it though...
12:51 PM Loetmichel: roycroft: nitpick. I meant that the copper foil only helps when it includes the door AND EMI gaskets
12:52 PM * travis_farmer still has to foil his enclosure door...
12:52 PM ZincBoy[CAON][m]: Yes, slot antenna for the win 🙂 Learned that on the hard way.
12:52 PM Loetmichel: its why we have to put a glass with a 100um copper mesh in front of the TFTs we sell
12:53 PM travis_farmer: and microwave ovens
12:53 PM Loetmichel: honestly: i wouldnt trust a 35um thick 100um mesh width copper mesh with 1kW microwave... i like my eyes!
12:54 PM Loetmichel: those oven usually have half a mm of steel plate with holes in it in front of the door
12:54 PM Loetmichel: NOT a copper mesh
12:54 PM travis_farmer: i was just pointing them out
12:55 PM Loetmichel: yes, and the usually have said emi gaskets, too
12:55 PM Loetmichel: on the door
12:55 PM ZincBoy[CAON][m]: If you want fun, try shielding 60Hz.
12:55 PM Loetmichel: ZincBoy[CAON][m]: easy. just needs a few pounds of mu-metal
12:56 PM Loetmichel: been there done that
12:56 PM ZincBoy[CAON][m]: Need mu metal as the coupling is magnetic
12:56 PM ZincBoy[CAON][m]: Doh, beat me
12:56 PM travis_farmer: lol
12:56 PM Loetmichel: <- does military grade EMI-shielding of PCs and peripherials for a living
12:59 PM travis_farmer: i am now wondering how to shield the cooling fan on my enclosure, and still have it work. maybe it could suck air through a lump of steel-wool ;)
12:59 PM Loetmichel: travis_farmer: depens on the frequencys you are dealing with
12:59 PM ZincBoy[CAON][m]: Had a RF design that used cutouts under the DC blocking caps to reduce parasitic capacitance. It would lose connection every time a cell connection came in. turns out the cutout formed a good antenna for the cell band. Needed a really good enclosure and the real solution was a redesign.
12:59 PM Loetmichel: rule of thumb is: hole can be as big as quarter the wavelength you want to shield
01:00 PM travis_farmer: Hmmm...
01:00 PM travis_farmer: maybe i will just take out the fan ;)
01:00 PM Loetmichel: We have to measure up to 4GHz... hence our biggest allowed holes are 2,5mm diameter
01:02 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17186&g2_imageViewsIndex=1 <- and thats the result of that.
01:02 PM Loetmichel: And yeah, the slots on the side were a mistake. had to put copper mesh on the inside
01:03 PM ZincBoy[CAON][m]: Ha, I was about to point them out
01:03 PM ZincBoy[CAON][m]: Looks very nice otherwise
01:03 PM XXCoder: travis_farmer: or leave fan in, but it blows into heat sink but does not have any air access to interior
01:04 PM XXCoder: and interior air to move air around and though heat sink on other side
01:04 PM travis_farmer: Hmmm, interesting idea...
01:04 PM Loetmichel: XXCoder: its better to use a watercooler or a bunch of heatpipes then
01:04 PM XXCoder: so you can transfer heat out of sealed enclosure, but you gonna know how much watt of heat
01:04 PM Loetmichel: and move the heatsinks to the outside
01:04 PM XXCoder: loet makes sense
01:05 PM ZincBoy[CAON][m]: This is what my mill enclosure does. There is a double sided heatsink with one side in the enclosure and the other outside. there is a big fan on either side to transfer the heat.
01:05 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17283&g2_imageViewsIndex=1
01:05 PM travis_farmer: just my stepper drivers and some SSRs that generate heat
01:05 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17286&g2_imageViewsIndex=1
01:05 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17280&g2_imageViewsIndex=1
01:05 PM Loetmichel: like that one
01:06 PM Loetmichel: and yes, those heatpipes are a LOT of "fun" to bend by hand
01:06 PM XXCoder: I guess you filled it with very low temp metal, then bent it
01:06 PM Loetmichel: ... for varying values of "fun"
01:06 PM roycroft: xxcoder: still no response from gst3d, so i now have a dispute filed at my cc company
01:07 PM roycroft: we'll see if they respond to that
01:07 PM Loetmichel: nope, they come sealed and ready to go
01:07 PM ZincBoy[CAON][m]: Nice. I like the heatpipes. Do you use an internal fan for air circulation?
01:07 PM XXCoder: yeah, hope you get conclusion you want
01:07 PM Loetmichel: just be careful to not "flatten" them while bending
01:07 PM Loetmichel: ZincBoy[CAON][m]: nope, that wouldnt have fitted inside there ;)
01:07 PM roycroft: i've also done some more digging into them, and i've seen several online complaints about them
01:08 PM XXCoder: very tight specced miliary thing
01:08 PM DigitalReaper: springs are sometimes used internally for bending pipes but they could probably be used externally too
01:08 PM XXCoder: it even looks very miliary :P
01:08 PM Loetmichel: its actually NOT a military project
01:08 PM XXCoder: hm wonder if their qa went down
01:08 PM roycroft: about filament that "explodes" when heated, even after pre-drying, filament that breaks randomly (part of my problem), filament that jams in the hot end (the other part of my problem), zero customer service (the biggest problem)
01:08 PM ZincBoy[CAON][m]: Yes, bending the pipes are a pain. I switched to water cooling as it was easier to deal with in low volume setups.
01:08 PM travis_farmer: yeah... after much thought, i could have down my control enclosure much better... may fix all that at some point...
01:09 PM roycroft: i saw two different posts that said "i ordered a spool or two and it worked fine, then i did a bulk order and it was shite"
01:09 PM roycroft: paraphrasing, of course
01:09 PM Loetmichel: was a "controlterminal" for a radio->SIP system for airports
01:09 PM roycroft: but that's my exact experience
01:09 PM ZincBoy[CAON][m]: bait and switch
01:09 PM roycroft: so anyway, i'll keep you updated on what transpires
01:09 PM XXCoder: thanks.
01:10 PM roycroft: i would strongly recommend putting any purchases from them on hold for now
01:11 PM XXCoder: yep was planning on army green and blue refills
01:11 PM XXCoder: Loetmichel: makes sense. want to be very tough when used for airports.
01:11 PM Loetmichel: but they DID had some funny specs. like "lower 10mm of the case has to be watertight so that in case of a fire the plastic innards that may melt can drip out of it and wreak havoc
01:11 PM Loetmichel: s/can/cant
01:12 PM Loetmichel: and size constraints and "silent"
01:12 PM ZincBoy[CAON][m]: LOL that is a new one.
01:12 PM roycroft: this thread is interesting:
01:12 PM roycroft: https://www.reddit.com/r/3Dprinting/comments/m49my2/gst3d_pla_any_good/
01:12 PM unterhaus: it wasn't supposed to rain until 9 tonight. Little dog say, "shows how much they know"
01:12 PM roycroft: VERY mixed reviews
01:14 PM travis_farmer: now i am wondering if i should shield my stepper drivers from the rest of the control box... may not be needed....
01:16 PM unterhaus: try not to parallel control and power wires. Shielding probably not necessary
01:16 PM ZincBoy[CAON][m]: Probably not needed. Doing it in a way that actually shields is going to be expensive and annoying.
01:16 PM travis_farmer: ok, so they may be fine as is. good to know
01:17 PM Loetmichel: well. If you have an AC spindle with chinese VFD: try to shield the cable from the VFD to the spindle AND the power cable to the VFD... those things are atrocious for EMI
01:17 PM Loetmichel: just a tip. Its always easier to shield the source than the drain
01:17 PM travis_farmer: the VFD is not in my control box
01:17 PM XXCoder: roy couple seem questionable, like lack of stick to bed, thats printer issue not filament. one might not be printing hot enough. rest seems to be indeed, filament issue like yours and other issues
01:17 PM ZincBoy[CAON][m]: This! those things are amazing for EMI
01:17 PM Loetmichel: i meant: the Chinese VFDs tent to be nice jamming transmitters
01:18 PM Loetmichel: very wide band
01:18 PM Loetmichel: and powerful signal
01:18 PM travis_farmer: but i could shield the wires for it
01:18 PM roycroft: yes, i filter out the stuff that is not related to the filament
01:18 PM roycroft: this is interesting, btw:
01:18 PM roycroft: https://nypost.com/2022/06/23/3d-printer-capable-of-making-guns-goes-missing-from-mta-yard/amp/
01:19 PM * roycroft writes an article "chunk of steel capable of being machined into gun parts goes missing from scrap yard"
01:19 PM ZincBoy[CAON][m]: So, a 3d printer.
01:19 PM XXCoder: its apparently very expensive machine, but guns thing is a gimmie
01:19 PM XXCoder: *grabbie
01:19 PM travis_farmer: i need to replace the VFD to Spindle cable anyway. it is just extension cord cable...
01:19 PM ZincBoy[CAON][m]: Just a commercial one so it is $$$.
01:19 PM Loetmichel: metal sintering?
01:19 PM roycroft: no
01:19 PM ZincBoy[CAON][m]: Not at 100k
01:20 PM roycroft: the article says it's for making "ghost gun parts"
01:20 PM roycroft: so no metal
01:20 PM ZincBoy[CAON][m]: 500k maybe.
01:20 PM Loetmichel: hmm
01:20 PM roycroft: so yes
01:20 PM XXCoder: zinc you can get metal sls for 40k or so
01:20 PM ZincBoy[CAON][m]: ghost guns can be metal.
01:20 PM roycroft: s/3d printer capable of making gun parts/3d printer/g
01:20 PM ZincBoy[CAON][m]: they just don't have a serial number/registration
01:20 PM Loetmichel: i dont know if i would trust thermoplastics of any kind to repeatedly withstand explosions ;)
01:20 PM roycroft: i don't like redundant expressions
01:21 PM roycroft: loetmichel: you don't use the gun parts you print
01:21 PM roycroft: you sell them to other people
01:21 PM XXCoder: yeah I guess it'd be perfect for one shot or something. I wouldnt trust it at all, not that I ever need a gun ever
01:21 PM ZincBoy[CAON][m]: LOL. You can get the printer, yes. But the sintering oven and rest of the setup is about 500k. I was looking at them a year ago.
01:21 PM _unreal_: so this sucks. as I mented a few days ago I had an other bad case of trigger hand. and I ended up dropping something. problem is it landed on my 3d printed ER11 COLLET holder. fucker exploded. and now I have found all but my 1/4" collet the one I need.
01:21 PM _unreal_: blowing my mind I still cant find it
01:22 PM XXCoder: unreal empty entire room ;)
01:22 PM _unreal_: and worse. I have a backup quote un quote. for my 1.2kw spindle. but I cant find ANY of those collets
01:22 PM _unreal_: I dont know what I did twith themn
01:22 PM * roycroft hands _unreal_ a big magnet
01:22 PM _unreal_: they are all MIA
01:22 PM _unreal_: its just mind blowing
01:23 PM XXCoder: ZincBoy[CAON][m]: interesting, thought all need to is laser ti powder for example, then its good to go
01:23 PM Loetmichel: roycroft: oh. i see. thats kinda cynic, dont you think?
01:24 PM roycroft: that was a joke, son
01:24 PM XXCoder: anyway that article is just crap
01:24 PM roycroft: it is almost lunch time, and my first systainer tray should be ready to install at lunch time
01:24 PM XXCoder: even fear mongering. "omg gun"
01:24 PM ZincBoy[CAON][m]: There is not a SLS metal printer for 40K that I am aware of. Plus the support setup for metal powder printers is pretty involved.
01:24 PM roycroft: well, yeah
01:24 PM roycroft: that's another redundant statement
01:25 PM Loetmichel: XXCoder: well, to be honest: MAKING a gun is a lot easier with just a few parts from a home improvement shop and some hand tools
01:25 PM roycroft: "article in new york post is crap"
01:25 PM roycroft: :)
01:25 PM Loetmichel: no 3d-printing needed
01:25 PM roycroft: the thing is, though, nyp readers won't know how ridiculous that article is
01:25 PM Loetmichel: ZincBoy[CAON][m]: yeah. a few 100W laser, enclosure, fat bottles of argon...
01:25 PM Loetmichel: pretty expensive in running costs, too
01:25 PM roycroft: because if they did, they would be smart enough to know that every article in the nyp is ridiculous
01:26 PM XXCoder: ZincBoy[CAON][m]: https://formlabs.com/3d-printers/fuse-1/
01:26 PM ZincBoy[CAON][m]: Plus the dust control and post wire edm to remove supports.
01:26 PM XXCoder: roy lol indeed
01:27 PM Loetmichel: ZincBoy[CAON][m]: the sort of printer i mean doesent use support
01:27 PM XXCoder: that ones not metal, plastic only though
01:27 PM roycroft: maybe my gst3d filament thought i was printing gun parts, not boxes, and that's why it stopped working
01:27 PM ZincBoy[CAON][m]: Yes, it does. They don't talk about it much though
01:27 PM XXCoder: lol
01:27 PM roycroft: hey
01:27 PM ZincBoy[CAON][m]: The metal moves around too much without supports.
01:27 PM XXCoder: zinc loet made his own sls
01:27 PM Loetmichel: it puts down a layer of dust, then lasers it then moves the platform down a layer than puts on a fresh layer of dust, lasers it. Afterwards you have to use a vacuum to get rid of the loose dust from around the part.
01:27 PM XXCoder: though dunno if can do metal
01:27 PM roycroft: if bill gates can put a tracking microchip in a vaccine, he can put a part detection chip in a spool of filament
01:28 PM XXCoder: roy that'd be insanely advanced
01:28 PM Loetmichel: XXCoder: nope, i dont make my own. YET
01:28 PM XXCoder: hmm might be misremembered with someone else. capt maybe?
01:29 PM roycroft: a nanogyroscope embedded in the chip could track movement of the hot end, and if that movement matched a gun part pattern embedded in the chip the chip could initiate an auto-destruct sequence
01:29 PM Loetmichel: roycroft: i think you could get a nobel prize for reverse kinematics software for that one
01:29 PM Loetmichel: :)
01:30 PM roycroft: is that idea any more crazy than embedding tracking microchips in a vaccine?
01:30 PM roycroft: especially a vaccine where there are five doses per vial
01:30 PM ZincBoy[CAON][m]: I know. Just for the metal versions there tend to be issues with warping/movement without supports.
01:30 PM Loetmichel: nah, not more insane. but about the same
01:30 PM roycroft: ok
01:30 PM XXCoder: maybe some people escaped vaccine chip and someone has all 5 lol
01:31 PM roycroft: and nyp readers buy into the bill gates microchip conspiracy theory
01:31 PM XXCoder: but if its that advanced, make it go one a time in :P
01:31 PM roycroft: so my theory about why my filament is failing would make a good story for that publication
01:32 PM roycroft: anyway, my part is done
01:32 PM roycroft: i have described the mechanism
01:32 PM roycroft: i'll leave it to others to implement it
01:32 PM roycroft: and then i'll collect my nobel, since it was my idea, after all
01:33 PM XXCoder: lol
01:33 PM XXCoder: ZincBoy[CAON][m]: https://youtu.be/oiEL4BGXQss pretty cool. I do want one but just no room or money lol
01:33 PM XXCoder: also cant do metal, but then its 20k usd at most
01:33 PM * roycroft heads out to install a systainer tray, and hopefully have complete success
01:37 PM ZincBoy[CAON][m]: Yes they are nice. The metal version is another order of magnitude due to the support reqs. I don't see metal powder SLS being practical for the home user anytime soon. It would need to be a sealed system as fine metal powder is really "fun".
01:41 PM ZincBoy[CAON][m]: Though there was that guy that was spraying photopolymer with a HVLP gun in his house and without a mask. That is up there with same level of danger I guess.
01:42 PM Loetmichel: well, the powder isnt actually THAT fine
01:42 PM XXCoder: isnt metal ones much more fine?
01:42 PM Loetmichel: 50um to 100um should work IIRC
01:43 PM Loetmichel: its not like "dust" and settles quite fast
01:43 PM Loetmichel: but it has to be enclosed anyways because it has to be molten in an argon athmosphere. Especially if aluminium or magnesium
01:43 PM Loetmichel: Stainless steel not so much
01:45 PM XXCoder: making stuff out of stainless steel souns fun
01:45 PM XXCoder: pricy im sure
01:46 PM XXCoder: I wonder how they make metal powders
01:46 PM XXCoder: nylon is much simpler, use dry ice and grind them down into powder
01:59 PM CaptHindsight[m]: ZincBoy[CA, ON]: SLS is currently expensive because they can sell them for the prices they are getting, same for powder bed fusion
02:00 PM CaptHindsight[m]: the most expensive part are the lasers
02:01 PM CaptHindsight[m]: galvos have come down to $200
02:01 PM CaptHindsight[m]: powder bed fusion is where the real profit margins are
02:02 PM ZincBoy[CAON][m]: Partially. High power lasers, heating systems and powder handling are not cheap. Plus the powder is expensive too.
02:02 PM ZincBoy[CAON][m]: They are conceptually simple but actually quite complex to get a working system.
02:03 PM CaptHindsight[m]: powders are expensive because they can get the prices they currently charge
02:03 PM CaptHindsight[m]: I've posted quite a bit on DIYing either
02:03 PM XXCoder: ah so it was you indeed
02:05 PM ZincBoy[CAON][m]: There is also a big difference between a nylon SLS system and one that can do metal. Nylon SLS is getting there as the formlabs offering shows. Metal is quite a ways off.
02:05 PM CaptHindsight[m]: Mesa even made a module for driving xy2-100 galvos
02:06 PM XXCoder: zinc I have formlabs sample. its impressive
02:07 PM CaptHindsight[m]: https://imgur.com/LxSPzg7 powder beds not shown
02:07 PM ZincBoy[CAON][m]: Yes, they have a good system. I have seen it in person and it is quite capable..
02:10 PM CaptHindsight[m]: I design and build custom versions all the time, SLS PJF, SLA ....
02:11 PM CaptHindsight[m]: heh PJF/PBF
02:11 PM ZincBoy[CAON][m]: There are a bunch of metal FDM/sinter systems that are quite capable and much more suited to home use. The big stumbling block there is the cost of the sintering oven.
02:11 PM XXCoder: peanut jelly fdm ;)
02:11 PM CaptHindsight[m]: materials are marked up 5-10x
02:12 PM CaptHindsight[m]: you can build an over for cheap
02:12 PM XXCoder: what temps do sindering oven need anyway
02:13 PM CaptHindsight[m]: start with a conventional oven, add some extra heating elements and some heat bricks
02:13 PM ZincBoy[CAON][m]: A controlled atmosphere oven with very accurate and even temp control? Not easily or that cheap.
02:13 PM * Loetmichel is thinking about bying an 80W china lasercutter and making my own SLS powder printer with it. Probably not alu, but stainless and Plastics should work. JUst for shits and giggles IF i can do it.
02:13 PM CaptHindsight[m]: argon or nitrogen is easy
02:13 PM ZincBoy[CAON][m]: Need 750 to 1400C
02:13 PM Loetmichel: will not be fast or "well made" of course.
02:14 PM Loetmichel: Argon is easy. aviable in any welding shop
02:14 PM ZincBoy[CAON][m]: Have you done this? I have. It isn't as easy as it sounds.
02:15 PM Loetmichel: i am aware that it will probably warp quite badly if not heated to approbiate temperatures.
02:15 PM Loetmichel: one of the reasons why i have postponed said plans for a while now
02:16 PM ZincBoy[CAON][m]: I meant the oven, not the SLS printer though that sounds like a big project as well.
02:16 PM CaptHindsight[m]: hard vs easy is subjective
02:17 PM Loetmichel: i have heard that the warping depends largely on how "sintered" the product gets though
02:18 PM CaptHindsight[m]: my kids used to ask me that question about making things, my answer was always "if you or I am doing it"
02:18 PM Loetmichel: and that its even possible to do it "at room temp" if you only make "baked powder" and fill the stainless "loofah" afterwards with brass
02:25 PM _unreal_: ok so now the the X axis stepper is now mounted to its adjustable mount. the mount is not mounted to the cnc frame yet
02:26 PM _unreal_: z dust shoe axis motor is now mounted to its adjustable mount. not mounted to the main Z frame plate yet.
02:32 PM CaptHindsight[m]: https://www.youtube.com/watch?v=lMi1P-J-nmY not sealed and only hot enough for aluminum and similar, he could seal it and add more elements and some fire bricks
02:34 PM CaptHindsight[m]: I'm building kilns and printers now for glass casting
02:46 PM CaptHindsight[m]: you are doing a good job of insulating if you get 2000C inside and <100C on the outer surface of the oven
02:47 PM CaptHindsight[m]: adding ports for inert gas is also just some plumbing
02:54 PM * CaptHindsight[m] uploaded an image: (189KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/dPZPxnZhliMZktGjlqFDbhtP/knurl00.png >
02:55 PM CaptHindsight[m]: how do you think this knurl was formed?
02:55 PM CaptHindsight[m]: inside knurling tool or?
02:55 PM CaptHindsight[m]: hob?
02:58 PM roycroft: clickspring made a knurling die that does that
02:59 PM roycroft: you could do it with a traditional knurling tool on the lathe
02:59 PM roycroft: or a number of other ways
03:00 PM CaptHindsight[m]: yes
03:00 PM roycroft: i suppose on the lathe a form tool to make the channel would be in order first, then the knurling tool with the convex die, and the carriage locked in place
03:00 PM CaptHindsight[m]: it's so crude it almost looks cast
03:00 PM roycroft: it's not crude
03:01 PM roycroft: it's 'artisan'
03:01 PM CaptHindsight[m]: uh huh
03:01 PM roycroft: that makes it worth more
03:01 PM travis_farmer: lol
03:01 PM CaptHindsight[m]: nuh huh
03:01 PM XXCoder: I saw one of videos of guy using machine tap to create that effect'
03:01 PM XXCoder: just rotate disk using tap, get closer and closer cutting threads
03:02 PM roycroft: it would be a good job for a hob
03:02 PM CaptHindsight[m]: and then place in a tumbler for a couple minutes to add the artisanal features
03:02 PM roycroft: but it would be fun to make a knurling die to do it
03:03 PM XXCoder: :( seems theres dangerous fad hobby and it killed few people so far and this video is warning on it https://youtu.be/GZrynWtBDTE
03:03 PM roycroft: i don't see a parting line in the middle, which to me makes it less likely that it was cast
03:04 PM roycroft: perhaps it was forged
03:04 PM CaptHindsight[m]: investment cast
03:04 PM XXCoder: images too small and blurry to be sure
03:04 PM roycroft: oh
03:04 PM roycroft: happy canadia day, eh?
03:04 PM * roycroft forgot to give tribute to the great white north
03:05 PM CaptHindsight[m]: XXCoder: have you tried the focus setting on your monitor?
03:05 PM XXCoder: lol
03:07 PM roycroft: that pic is not in sharp focus, but it's clear enough to get a good idea what it is and how it could and could not have been made
03:07 PM roycroft: i'm betting on some kind of form tool
03:07 PM CaptHindsight[m]: always wear rubber insulating pants when working around HV
03:07 PM roycroft: it looks squished more than cut
03:08 PM XXCoder: cap id not do it at all, even if I know how to handle hv
03:08 PM CaptHindsight[m]: squishing tool shows few results
03:08 PM CaptHindsight[m]: plus this has to squish out near the edges
03:09 PM CaptHindsight[m]: I heard that squishing in is easier than squishing out
03:09 PM roycroft: https://www.mcmaster.com/32915A77-32915A615/
03:09 PM roycroft: something like that
03:10 PM CaptHindsight[m]: 403 - Forbidden: Access is denied. foiled again!
03:11 PM roycroft: a world without mcmaster would be a difficult one to navigate
03:11 PM roycroft: i feel your pain
03:12 PM CaptHindsight[m]: but i am still pretty certain that a tool is involved in it's fabrication
03:12 PM CaptHindsight[m]: its/it's
03:12 PM roycroft: http://www.frets.com/HomeShopTech/Projects/RopeKnurl/ropeknurl.html
03:12 PM roycroft: i wonder of any of that looks familiar
03:13 PM CaptHindsight[m]: if prayed works so well for school shootings is it worth investigation for machining as well?
03:13 PM CaptHindsight[m]: s/prayed/prayer/
03:14 PM _unreal_: sigh.... been 2 years since I purchased that @!#$@#%4 1.2kw spindle. I cant believe i've lost alll parts to it except for what is sitting on the new machine. I have beyond NO idea what I did with them. it makes no sense.
03:14 PM * roycroft refers capthindsight to picture #8 in that link
03:14 PM CaptHindsight[m]: hey you found where he copied that pic from
03:15 PM roycroft: we've been looking at the tool, not the knurl
03:15 PM roycroft: so mystery solved
03:16 PM CaptHindsight[m]: didn't try a reverse image serach
03:16 PM roycroft: i didn
03:16 PM roycroft: t either
03:16 PM roycroft: but something about that picture looked familiar
03:16 PM roycroft: and i remember reading an article about making rope knurls, so i googled "convex rope knurl", and found the article
03:16 PM roycroft: which i read years ago
03:28 PM _unreal_: WHOLY FUCK I just found the last missing collet
03:28 PM _unreal_: sitting behind/under the netbook that drives the little cnc machine
03:28 PM CaptHindsight[m]: i think i saw that film
03:28 PM _unreal_: I sware I picked it up before and it was not there
03:28 PM _unreal_: mind blowing
03:29 PM travis_farmer: i hid it there, _unreal_ ;)
03:34 PM _unreal_: You bastard
03:34 PM travis_farmer: LMAO
03:36 PM CaptHindsight[m]: the last missing collet, starring Matt Damon
03:37 PM CaptHindsight[m]: a lonely out of work machinist goes for broke one last time to find love
03:40 PM _unreal_: ok so finally after not being able to do anything for some time. now I can try to finish the last major parts to my cnc machine
03:55 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/reprap/drive4.jpg
03:56 PM Tom_L: not hard to do
03:59 PM XXCoder: just had job interview
03:59 PM XXCoder: it was... interesting
04:00 PM travis_farmer: McDonalds?
04:00 PM XXCoder: i dont think I rocked the interview, but it wasnt a failure
04:00 PM XXCoder: nah tech support for 3d printers
04:00 PM travis_farmer: Hmmm...
04:00 PM Tom_L: don't wanna go back to loading parts?
04:00 PM XXCoder: I still cant work safely on cnc machines
04:00 PM XXCoder: pay pay is higher if full time
04:01 PM XXCoder: *and
04:02 PM Tom_L: after my kid got covid layed off 2x he went back and did hvac and starting out $7 more per hr than he was getting
04:02 PM Tom_L: and covid relief paid for his hvac training
04:02 PM XXCoder: $10 more for me. more or less
04:03 PM Tom_L: pulls units off the assembly line for engineering testing
04:03 PM XXCoder: thats nice :)
04:04 PM Tom_L: they have environmental cells they put them thru hell and back
04:04 PM JT-Shop: True is building a huge commercial/industrial refrigeration plant here
04:05 PM Tom_L: there is some type of refrigerant that is combustible... i dunno what it is
04:05 PM XXCoder: keserone?
04:05 PM Tom_L: he works with several types
04:05 PM Tom_L: i've no idea
04:05 PM XXCoder: it is refergant, but also used in lamp lights
04:06 PM _unreal_: ok quick edit on the code speed things up a bit
04:06 PM _unreal_: amazing. I've never used a 1/2" bit on the little cnc before but its taking it like a champ
04:06 PM _unreal_: cutting HDPE 3mm plunge depth 100mm feed rate no issues
04:08 PM JT-Shop: XXCoder, a work from home type of job?
04:09 PM XXCoder: yeah. id not have applied otherwise
04:09 PM _unreal_: When I get to it. I'm going to redesign my cyclone separator. I'll end up posting it on thing verse. but I'm going to make it better then it is
04:09 PM _unreal_: and and will have to be 3d printed
04:14 PM Tom_L: JT-Shop, anything new to test?
04:15 PM CaptHindsight[m]: machinist jobs are rarely remote
04:15 PM CaptHindsight[m]: unless it's one of those mobile shops
04:15 PM _unreal_: ve7it, sup
04:15 PM JT-Shop: Tom_L, no, we went on a ride today
04:15 PM XXCoder: it exists, its called owning home shop with contracts ;)
04:15 PM Tom_L: nice
04:16 PM CaptHindsight[m]: speaking of pulleys with knurls, what is the best type of pulley to use with glass fibers?
04:16 PM Tom_L: JT-Shop, any place interesting?
04:16 PM CaptHindsight[m]: they don't compress
04:17 PM CaptHindsight[m]: so should the pulley compress vs the fiber
04:17 PM Tom_L: glass fibers as the belt?
04:17 PM Tom_L: rubber pulley
04:17 PM travis_farmer: hey JT, by chance are you o the goldwingowners.com forum?
04:17 PM travis_farmer: on, not "o"
04:17 PM CaptHindsight[m]: belt, fiber or rod
04:18 PM JT-Shop: I was on a goldwing forum but have not been on in years
04:18 PM CaptHindsight[m]: how about hot glass fiber say > the melt temp of rubber
04:18 PM travis_farmer: hmm, ok, just thought i recognized your pic from on there...
04:19 PM CaptHindsight[m]: maybe an aluminum oxide pulley
04:19 PM JT-Shop: we went to the end of the road at Scott City to The River House winery, you're right on the river and you can see the courthouse Lincoln practiced law in across the river
04:20 PM JT-Shop: then up to Perryville via back roads to Stonies for some sweet german baloney
04:20 PM JT-Shop: averaged 32MPG in the Corvette
04:21 PM CaptHindsight[m]: https://g.page/dw1311?share
04:22 PM JT-Shop: I looked at the hole in the nozzles that came with the ender 3 and it's a wonder it even prints the hole is not round or smooth
04:22 PM _unreal_: ugh. wish this phase of milling would be done
04:23 PM roycroft: my ender 5 stock nozzle seemed ok
04:23 PM roycroft: and i got some nice prints with it
04:23 PM JT-Shop: I have some new ones coming various diameters
04:23 PM Tom_L: https://www.bdhbelts.com/belt-guides
04:24 PM XXCoder: jt yeah if I got a ender 3 for free, i'd swap heat break and nozzle right away. even if it looks fine
04:24 PM XXCoder: you nbever go cheap on nozzle and heat break
04:25 PM JT-Shop: heat break is the finned bit above the heater?
04:26 PM XXCoder: no thats heat sink
04:26 PM XXCoder: its the metal neck that connects heat sink to heat block
04:26 PM XXCoder: those 2 parts is what actually touches filament
04:26 PM XXCoder: (for hotend assembly)
04:27 PM JT-Shop: ah
04:27 PM XXCoder: mine is overkill with titanium heat break and tungsein carbide nozzle
04:28 PM XXCoder: zero problems so far
04:29 PM XXCoder: honestly stainless steel heat break would work fine. titanium is barely more resistant to heat transfer
04:31 PM roycroft: i am on vacation in a half hour
04:31 PM XXCoder: yay
04:31 PM roycroft: yeah, i am ready
04:32 PM XXCoder: I saw one interesting heat break, the end that goes in heat block is stainless steel, the part that goes into heat sink is copper
04:32 PM XXCoder: so what little heat makes it across stainless steel is rapidly sucked up by copper then put out into alum fins
04:38 PM JT-Shop: roguish[m], I sent you to the wrong repo it's https://github.com/jethornton/gcode
04:47 PM roycroft: a ceramic heat break would be interesting
04:49 PM XXCoder: yeah
04:50 PM roycroft: it might be hard to get it smooth enough
04:50 PM roycroft: i mean, it can be glazed on the inside, but to keep the precise diameter could be a bit tricky
04:51 PM roycroft: i'm like all caught up on work
04:51 PM roycroft: but there's still 8 1/2 minutes to go today
04:52 PM roycroft: i anticipate my boss will send me an email or call me at 2:59 with something
04:52 PM roycroft: he's good at that
04:52 PM roycroft: very good at that
04:52 PM roycroft: i'll be ready to glue up the second tray right after work, and then i have to head out to the fair to check on our booth inspection
04:52 PM roycroft: i'll glue up two more trays tonight
04:53 PM roycroft: the systainer trays are such a tight fit
04:53 PM roycroft: the reason i'm making them different to the drawers is because i need that extra 12mm of depth to fit two systainers
04:53 PM roycroft: and two systainers *barely* fit
04:54 PM roycroft: but they fit :)
04:54 PM XXCoder: nice
04:56 PM JT-Shop: printing Atomic PTEG at 250C and I can hear the extruder skipping...
04:57 PM roycroft: i print atomic petg at 220
04:57 PM JT-Shop: I wonder if that nozzle is too small
04:57 PM roycroft: or maybe your heat sensor is off
04:57 PM roycroft: try 270 :)
04:58 PM XXCoder: id get k-type heat sensor and see temperate directly see if it matches printer temp
04:58 PM * JT-Shop puts the battery in the Fluke Temperature meter
05:00 PM roycroft: in 30 seconds i have to dnd my phone, close my email window, and enable my .forward to vacation simultaneously
05:00 PM roycroft: all done :)
05:01 PM roycroft: i've never used sliding dovetails to attach drawer fronts before, btw
05:01 PM _unreal_: good lord. ok just finished setting up my tooling path in estlcam
05:01 PM roycroft: it's working out very nicely
05:02 PM _unreal_: lot of offets because of different depths on a lot of pockets
05:02 PM roycroft: i shall have to do this again
05:06 PM JT-Shop: atomic petg recommends Print nozzle temp - 232 - 265C Heated Bed temp - 80c +-10C
05:20 PM JT-Shop: https://www.matterhackers.com/store/l/micro-swiss-direct-drive-extruder-for-creality/sk/MDZMAR3N
05:21 PM roycroft: i have not used a direct drive extruder
05:21 PM roycroft: i'm concerned about the extra mass on the z axis
05:21 PM * roycroft heads off to the fair
05:22 PM JT-Shop: as slow as X axis move I don't see an issue but the thought did cross my mind
05:26 PM _unreal_: checking. checking again, checking again. god I hate milling jobs with multi different depths
05:26 PM _unreal_: pocktes
05:37 PM andypugh: I wonder if I should just give up on Glade and do my lathe macros from scratch in something else? (Not, though, ~Scratch)
05:38 PM andypugh: Maybe QTCcp or QTPyVCP (We have too many VCPs)
05:42 PM JT-Shop2: QtPyVCP is very flexible, you can do anything you want
05:44 PM * JT-Shop2 wonders why he made the top to the egg drawer so thick
05:45 PM JT-Shop2: it's taking forever to size it in the drum sander
05:46 PM JT-Shop2: 12 more passes should do it
05:52 PM JT-Shop: a guy from India wanted to buy a bunch of Mesa cards with a company purchase order... I fell out of my chair laughing at that
05:52 PM unterhaus: that's why I have a scrub plane. Or a stanley no.7
05:53 PM JT-Shop: I don't have a scrub plane or a stanley #7, I do have 3 stanley #5's and one is over 100 years old
05:54 PM JT-Shop: I'm down to 0.010" so I'll let it cool over night and finish up in the morning
05:55 PM Tom_L: what's the matter JT-Shop, you don't wanna send free boards to india?
05:55 PM JT-Shop: or boards I don't even have lol
05:55 PM Tom_L: i had one guy want something from dubai
05:57 PM Tom_L: there were 3-4 places i didn't ship to
05:57 PM JT-Shop: I tell them what I used to tell my daughter "wish in one hand, crap in the other and see which one fills up first"
05:58 PM JT-Shop: as of late I ship to AU and NZ and that's about it
05:58 PM Tom_L: how do you filter out the others?
05:58 PM JT-Shop: oh and Cnuck land
05:59 PM JT-Shop: I don' have shipping enabled to any other countries
05:59 PM Tom_L: their post has actually gotten better of late
05:59 PM Tom_L: Ca that is
05:59 PM JT-Shop: I use woocommerce
05:59 PM Tom_L: ahh
05:59 PM JT-Shop: I had cards to up there go to the wrong city and the chap had to run them down
06:04 PM JT-Shop: I built some drawers for tools for a table I had years ago and a wood working buddy commented I wouldn't build them like that... my reply your not a machinist
06:24 PM JT-Shop: 2 amazon orders are arriving sunday somehow
06:55 PM Tom_L: JT-Shop, cnc menu install works
07:01 PM -!- #linuxcnc mode set to +v by ChanServ
07:04 PM Tom_L: JT-Cave, i don't see where Max Acceleration for the spindle is used
07:04 PM Tom_L: RPM/S/S
07:06 PM Tom_L: I/O vs GPIO tabs? GPIO appears unused but what's the difference?
07:07 PM Tom_L: i know some tabs aren't done yet..
07:10 PM Tom_L: A program error occurred in updates.py lnie 65 'str' obj has no attribute 'curentData'
07:10 PM Tom_L: caused when clicking on 'Documents' menu item
07:14 PM Tom_L: update version info from 0.6.5 to 0.7.0 in the header
07:14 PM Tom_L: package manager shows 0.7.0 installed
08:06 PM andypugh: JT-Shop: JT-Cave I think your export policy might be having wierd effects, like someone asking PCW to source from you and ship to them: https://forum.linuxcnc.org/27-driver-boards/46153-another-way-to-interface-panel-then-7i73#246276
08:20 PM Tom_L: JT-Cave, possibly add TOOL_EDITOR parameter to the Display tab for colum display
08:20 PM Tom_L: (next to or below G code Editor)
08:21 PM Tom_L: checkoff colums to display?
08:33 PM _unreal_: ugh... about an hour to go cutting out this dust shoe axis plate
08:34 PM _unreal_: its going to be so damn nice having an independent dust shoe.
08:34 PM _unreal_: and I'm loving my design.
08:34 PM _unreal_: once this part is cut. the only parts I have left to make MAJOR parts
08:35 PM _unreal_: are the 4 X axis carriage stand offs
08:35 PM _unreal_: hate the idea of moving my spindle further away from the x axis rails. but at least it will give me my dust shoe axis
08:50 PM Tom_L: is halshow.preferences file something new for 2.9?
08:52 PM Tom_L: seems so
08:52 PM Tom_L: that's kinda cool
08:53 PM Rowow[m] is now known as Rowow5457[m]
08:56 PM Tom_L: that's very cool!
09:02 PM _unreal_: blaaa last pass then I need to switch to a micro drill bit to put the 8 screw holes in
09:02 PM _unreal_: I should have done that first but oh well
09:02 PM _unreal_: and BLAAA m2's
09:03 PM _unreal_: cant be helped though. the rails take 2mm screws being the 7mm rail type
09:09 PM roycroft: the pizza is in the oven finally
09:09 PM roycroft: late dinner tonight
09:09 PM XXCoder: yay thanks for baking for me
09:10 PM roycroft: but i've been making systainer trays, and trying to deal with our booth at the fair
09:10 PM roycroft: the verdict on the booth is this: i have no idea if it's going to pass inspection or not
09:10 PM roycroft: and i need to show up at 9 o'clock sharp tomorrow to get in the queue to get an inspection
09:11 PM roycroft: i signed up for inspection days ago, but they can't find the notebook where i signed up, so i'm at the back of the queue again
09:12 PM roycroft: so i have no idea whether i have a day and a half of work to do in one day or not
09:12 PM roycroft: and tomorrow is that day - it's the only day i have a helper
09:12 PM roycroft: if i don't have a helper that day and a half could be 2 and a half days
09:12 PM Tom_L: make sure it's up to rigid building code and you'll be golden
09:12 PM roycroft: and it has to be done and inspected by sunday
09:12 PM roycroft: it is up to code
09:13 PM roycroft: but that doesn't mean anything
09:13 PM roycroft: it's at least as solid as it's ever been
09:13 PM roycroft: but again, that does not mean anything
09:13 PM roycroft: i'm at the whim of the inspector
09:13 PM roycroft: in that respect, the country fair is no different at all to the outside world
09:13 PM Tom_L: i had an inspector once that _had_ to find something
09:14 PM Tom_L: and i had another one that asked me several times.. is this ok?
09:14 PM roycroft: i was doing a fiber project a few years ago for a local city
09:14 PM roycroft: i was working for the city - i was a contract project manager for the city
09:14 PM roycroft: the building inspector, who also worked for the city, did not take kindly to me
09:15 PM roycroft: he was pissed off at me from day one, i think in large part because i look like a hippie and he looks like a marine
09:15 PM roycroft: at one point i called for an inspection, he showed up early, and there was no ladder waiting for him
09:16 PM roycroft: he totally freaked out and said he's fining me for not having a ladder ready
09:16 PM XXCoder: geez
09:16 PM roycroft: i said "ok, you can do that, but i'll just pass the fine on to the city, since i'm working for and representing them"
09:16 PM roycroft: that got him even more pissed off, and he started screaming that he is going to fine me PERSONALLY, and that he would ensure that the city does not pay the fine
09:16 PM roycroft: and he did
09:17 PM roycroft: it was a $250 fine
09:17 PM roycroft: which i passed on to the city
09:17 PM roycroft: and they paid
09:17 PM XXCoder: lol literally like you said would happen
09:18 PM roycroft: i should note that his contract with the city was not renewed the next year
09:18 PM roycroft: and i did several other fiber projects for that city
09:18 PM roycroft: i don't think my fine was the only reason his contract was not renewed
09:19 PM roycroft: but i do think it was typical of the types of behaviors he exhibited that caused him to be let go
09:19 PM XXCoder: he probably judged bunch more people based on looks
09:19 PM roycroft: well, also, building inspectors are often failed contractors
09:19 PM roycroft: and they are often resentful because they failed as a contractor
09:20 PM Tom_L: and shop teachers are ....
09:20 PM roycroft: kind of like english teachers are failed writers
09:20 PM Tom_L: the list goes on
09:20 PM roycroft: and music teachers faild musicians
09:20 PM roycroft: :)
09:20 PM XXCoder: lol well I liked my wood shop teacher. he was awesome. I just wish I had second semster I was supposed to
09:21 PM XXCoder: mr hammer died right after my first class by heart attack. that sucks
09:21 PM Tom_L: mine was a cool guy
09:24 PM Tom_L: so halshow at least thru the axis menu is alot more interactive in 2.9
09:24 PM Tom_L: and it saves your session
09:31 PM _unreal_: I think its safe to say this dust shoe axis has been one of the most complex designs I've delt with in a while
09:31 PM _unreal_: for milling
09:31 PM _unreal_: few holes left to drill
