12:22 AM XXCoder: yo
12:41 AM {HD}: Ugg
12:41 AM XXCoder: found something new?
12:43 AM Cromaglious_: I need to fix my K40, I've had the new yube for a year and haven't put it in yet and I have the Z table as well
12:46 AM Cromaglious_ is now known as Crom_
01:34 AM mark-otaris is now known as Guest77272
01:46 AM Deejay: moin
01:54 AM hazzy-lab1 is now known as hazzy-lab
02:03 AM sealive: morning from germany
02:07 AM XXCoder: hey
02:07 AM Deejay: your nick is wrong!
02:08 AM fragalot: Hey sealive
02:08 AM sealive: its a mess with this bots
02:09 AM sealive: im off filling watertanks for the next heat wave
02:11 AM Wolf__: using nickserv is complex….

07:39 AM sealive: hi all
07:39 AM sealive: still only registerd use
07:42 AM sealive: sun is out now for the firt time today so hedding towards garden
08:34 AM * Loetmichel is just deburring sheetmetal and mounting some Network switch enclosures... maan that takes forever... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17177&g2_imageViewsIndex=1 (and i should probably clean my desk a bit ;)
09:26 AM are is now known as Guest29214
10:23 AM skunkworks: https://www.model-engineer.co.uk/forums/postings.asp?th=137228
10:26 AM skunkworks: 'linuxcnc is too complicated... I would rather create it from scratch..' Hey maybe a pll ;)
10:29 AM jesseg: lol
10:29 AM jesseg: I created my own primitive replacement for LinuxCNC in perl. It's not GUI though, it's CLI with an interactive text menu.
10:29 AM jesseg: but I use it and it works most of the time LOL
10:36 AM skunkworks: http://electronicsam.com/images/greenmachine/20180812_121257.jpg
10:43 AM skunkworks: JT-Shop: back?
10:44 AM JT-Shop: dang freenode banned me lol
10:44 AM skunkworks: what did you do!
10:44 AM JT-Shop: I don't know I slept through it lol
10:44 AM skunkworks: Is it from your 'shared' sat ip address?
10:44 AM JT-Shop: hexchat keeps trying to connect and I think that pissed them off
10:45 AM skunkworks: ah
10:53 AM {HD}: Wolf__: I posted some data on the flatcam discussion which led to finding this: https://bitbucket.org/marius_stanciu/flatcam_vispy_pyqt4
10:54 AM {HD}: I only tried it with default so far which yielded the same results but there are many more options to play with.
10:55 AM Wolf__: hmm
10:55 AM Wolf__: have to wonder if that artifact in the engraving is coming from the gerber
10:56 AM skunkworks: are you sure it insn't and artifact of grbl?
10:56 AM skunkworks: you have run it a lot of different gcode with the same results?
11:00 AM skunkworks: (or your machine)
11:00 AM Wolf__: I ran his nc file on my laser and got the same artifact
11:03 AM skunkworks: ah..
11:06 AM ziper: jesseg, only because it looks like another boat will win
11:20 AM sealive: hi all
11:25 AM sealive: you cand welcome peopple here as you dont know if it is a spam bot
11:25 AM sealive: china IP
11:25 AM sealive: from sezuan province
11:26 AM sealive: and the bot has quit
11:27 AM sealive: Loetmichel, getting hit by the torainchial rain fall
11:41 AM jesseg: ziper, ahhh well but the experience! maybe next time you will win because of what you learned this time!
11:43 AM sealive: learning by doing is somewat expensive
11:44 AM jesseg: let me think about that for a minute. And you please think about it for a minute. Then we can both comment on the absurdity of it. :D :D :D
11:45 AM jesseg: I'm sorry my friend I shouldn't say that before having breakfast :D
11:50 AM sealive: im on the way for evening diner in germany
11:50 AM fragalot: hey
11:50 AM sealive: ;-)
11:50 AM fragalot: sealive: don't you always have an evening dinner in germany?
11:50 AM sealive: 10minutes to go
11:50 AM jesseg: sealive, enjoy! But I would say that there is a kind of learning that essentially comes only by experience. Anything that's less costly then that isn't going to equal it.
11:51 AM ziper: jesseg, look, they are only a few hundred km from the finish https://www.microtransat.org/tracking/index.php?fullscreen
11:51 AM ziper: i don't want to be the second first transatlantic
11:51 AM jesseg: And in fact that's I think the problem with a lot of engineering - people are working from pure book learning and they miss many important aspects.
11:52 AM fragalot: jesseg: agreed, a lot of knowledge is being lost that way
11:52 AM jesseg: There's nothing like real world hands on failures to fill in the gaps from cut and dried printed theory
11:52 AM fragalot: especially as some schools still use books that are obsolete or had print errors in them that were corrected at a later date
11:52 AM jesseg: and in my opinion, the cost of doing that is worth every last penny
11:52 AM ziper: how the heck do i calculate the strength of a laminate with a given composition and cross section
11:52 AM fragalot: jesseg: only if it's someone elses' penny :D
11:52 AM ziper: i dont want to waste a couple thou in carbon fiber
11:53 AM fragalot: ziper: there are 2 ways
11:53 AM fragalot: manually, or with a finite element analysis tool :P
11:53 AM jesseg: fragalot, that makes it worth even more LOL but still... if you really want to be good at a subject it takes real practice :D
11:54 AM jesseg: ziper, well I can sympathize with that.
11:54 AM jesseg: but again, I'd make it out of cheap things like styrofoam and fiberglass
11:54 AM sealive: im off Gn8
11:54 AM ziper: what tool?
11:54 AM jesseg: GOod night!
11:54 AM ziper: i tried solidworks and didnt like it
11:54 AM ziper: almost certainly because i dont know how to use it
11:54 AM ziper: or possibly because it doesnt model laminates well
11:57 AM fragalot: steep learning curve on whatever tool you use
11:57 AM fragalot: if you don't know how to use it, even a $20k tool won't help you :)
01:48 PM Deejay: re
01:56 PM {HD}: Whoops.
01:57 PM {HD}: Wolf__: that is just a test pcb I whipped up in kicad and exported gerber. There is nothing special with it. I can try a different kicad design but I dont have eagle or anything to test different gerber generation.
01:58 PM Wolf__: ahh
01:58 PM Wolf__: wonder if its something kicad is doing
02:00 PM Wolf__: just 0.125” circle pads right?
02:01 PM {HD}: That would suck. The .grb and .pcb and everything is in the repo. Yes approximately
02:02 PM {HD}: Kicad is my jam! It is my favorite for pcb design.
02:02 PM Wolf__: I have eagle and altium
02:02 PM Wolf__: maybe I’ll test a similar sample
02:03 PM {HD}: I quit eagle after autocad. And isnt altium like $10k?
02:03 PM Wolf__: call it a “demo” version
02:04 PM Wolf__: I haven’t done any board work in a few years tho
02:05 PM {HD}: I have the svg and dxf files in there too. Maybe just eagle import svg export gerber...to see if it is the kicad gerber-er.
02:06 PM {HD}: Anyway I am going to go see if I can tweak something in the ‘secret’ version of flatcam.
02:06 PM Wolf__: hmm
02:08 PM Wolf__: try using the svg or dxf in laser web
02:13 PM Loetmichel: hihihi... my wife is sitting there watching american late night shows. Her comment: "king george must be sitting in his grave laughing his ASS off... "and thats what you foght a war against monarchy for?!?""
02:15 PM MrHindsight: we reserve the right to be stupid!
02:21 PM {HD}: Wolf__: they work just fine but I can’t do multi pass isolation routing on them to get thicker isolation.
02:23 PM MrHindsight: Loetmichel: it's in one of our uhmendments
02:24 PM Loetmichel: {HD}: multipass... and now i have leela happily blubbering away on my imagination... thanks ;)
02:24 PM Loetmichel: MrHindsight: looks certainly like it ;)
02:24 PM Wolf__: {HD}: hmm, might be worth trying eagle or something. tho no idea how it works, last boards I did were toner transfer
02:25 PM {HD}: Loetmichel: ha
02:26 PM Loetmichel: Wolf__: you could give Target 3001 a try... it has a VERY sophisticated GCODE exporter
02:27 PM Loetmichel: s/leela/leelo
02:31 PM MrHindsight: {HD}: just being nosy, what are you trying to do different with the PCB routes?
02:34 PM {HD}: MrHindsight: the stem of the issue is an error caused in the output of laser etching a pcb. The pcb tracks/routes now are just test shapes/angles to provide a complete test of the machine.
02:34 PM {HD}: https://github.com/a7hybnj2/KicadStuffs/tree/master/Issues%20I%20have%20been%20having
02:35 PM {HD}: Here is all of the support material including pictures illustrating the issue.
02:35 PM Wolf__: so that nc file isnt as drawn, but using some post processing to add in the isolation width?
02:36 PM {HD}: Wolf__: huh?
02:37 PM Wolf__: your drawing just the pad and trace, then the cam is adding the pathing to engrave the isolation?
02:37 PM {HD}: Yes
02:38 PM fragalot: shouldn't there be a "spindle off" for each rapid?
02:38 PM Loetmichel: Wolf__: in target the insulation thickness is identical to the "rubout" thickness defined in the trace
02:38 PM Loetmichel: AND you can define seperate "cleanout" stretches
02:39 PM Wolf__: idk how that works, I usually do full board design then use the output direct from the board cad
02:39 PM Wolf__: more of a what you see is what you get
02:39 PM Loetmichel: fragalot: most CNC spindles need 2-5 seconds to spinup/spindown... that would make programs VERY slow
02:40 PM MrHindsight: I have too any questions to be of any use today
02:40 PM Wolf__: all of my milling spindle on until its done or I need tool change
02:41 PM MrHindsight: move Z up vs spindle off
02:41 PM fragalot: Loetmichel: this is a laser we're talking about
02:41 PM MrHindsight: are we?
02:41 PM Wolf__: laser depends on the controller
02:41 PM Loetmichel: lasers usually use a certain "z height" as trigger
02:41 PM {HD}: Yes all of the lasory stuff is handled by hardware.
02:41 PM Loetmichel: not the spinle commands
02:42 PM fragalot: alrighty :)
02:42 PM * fragalot only has limited experience with laser projectors, not engravers
02:42 PM MrHindsight: fragalot: what's new in tulip town? :p
02:42 PM Wolf__: mine does laser off on G0 moves
02:42 PM fragalot: MrHindsight: I bought a schaublin 13
02:42 PM Wolf__: iirc
02:43 PM fragalot: MrHindsight: and cancelled the Moai to fund it >.>
02:43 PM MrHindsight: http://static.webshopapp.com/shops/036767/files/071529740/sold-schaublin-13-parts-and-accessories.jpg
02:43 PM {HD}: I could make my own post process or change all of the Z moves to laser on and laser off. However because of the hardware take care of that already I do not need to
02:43 PM MrHindsight: fragalot: you can build a SLA/DLP printer for cheap
02:44 PM fragalot: MrHindsight: I can, but that may be for another day
02:44 PM MrHindsight: time
02:44 PM MrHindsight: schaublin 13 sounds like a movie title
02:44 PM fragalot: hehe
02:44 PM fragalot: I can't find anything bad about them
02:45 PM Loetmichel: fragalot: i also have seen them usimg custom M1xx commands instead of M06/M03
02:45 PM fragalot: I went to a "local" (read: another country) machine reseller to look at some Deckels
02:45 PM fragalot: spotted a schaublin 13 that I fell in love with.. And bought one somewhere else
02:45 PM MrHindsight: nicer than those chinese drill mill things
02:45 PM Wolf__: yup, I was thinking right, G01 moves = laser on, G00 moves = laser off
02:46 PM Wolf__: but thats a firmware thing w/ the controller anyways
02:46 PM Sabotend_ is now known as Sabotender
02:47 PM MrHindsight: oh and it's Swiss made, makes the Germans and Japanese look sloppy :)
02:47 PM fragalot: MrHindsight: :-)
02:47 PM fragalot: it's a 1968 (I think) model
02:47 PM MrHindsight: even machines suffer from nationalism/racism
02:48 PM fragalot: came with a standard vertical head, high-speed head, geared dividing head so I can cut spiral gears, and a bunch of toolholders
02:49 PM MrHindsight: is 3x380V common there?
02:49 PM fragalot: yes
02:50 PM fragalot: homes are typically 1x240V for older, or 3x220V for newer
02:50 PM fragalot: i've got 3x240V and a 5kW transformer in my shed for 380V
02:50 PM fragalot: s/220/240/
02:51 PM fragalot: any form of industrial building or farmer will likely have 380V
02:52 PM MrHindsight: most farms here have only single phase 2 pole 120/240
02:52 PM MrHindsight: one of the reasons I could not find a location too far out from civilization
02:52 PM {HD}: Wolf__: yep. I just found in the new cam a grbl_laser post-processor but it initially messed up laserweb.
02:53 PM fragalot: MrHindsight: ew. :P
02:53 PM MrHindsight: they only put one HV phase on the poles way out in Green Acres
02:53 PM fragalot: i've never quite understood the appeal of 110V
02:53 PM MrHindsight: you learned from out mistakes
02:54 PM fragalot: :D
02:54 PM MrHindsight: AC power, color TV, marrying cousins etc
02:54 PM fragalot: 3 phase is also quite a lot nicer than a single phase
02:54 PM fragalot: for distribution at least
02:56 PM MrHindsight: 3 phase is difficult to get in residential areas
02:57 PM {HD}: And its stupid expensive if you do have 3phase. They charge you peak charges and crap...its silly
02:57 PM Wolf__: I cant wait to find out how much 3 phase might cost at my house, if they will even install it
02:57 PM fragalot: all you need is a 300A service and one of those crappy phase converters :D
02:58 PM fragalot: Wolf__: friend of mine bought a workshop & had to have a new connectio installed
02:58 PM MrHindsight: we are in a 100K sq ft (9k sq m) building and they only brought in 120/208 3p
02:58 PM fragalot: existing 3x380V was from the previous owners' house
02:58 PM fragalot: cost him €15k
02:59 PM MrHindsight: the HV transformers are across the parking lot, and comes in underground
02:59 PM fragalot: MrHindsight: depends on what you requested doesn't it?
02:59 PM Wolf__: I’m on a main road, has 3p transmission so might be doable
02:59 PM MrHindsight: yeah, they cold have gotten 480 3p but then they would have had to put transformers inside the building
03:00 PM MrHindsight: the owner was too cheap for that
03:00 PM MrHindsight: cold/could
03:00 PM fragalot: Boo. :P
03:00 PM fragalot: that's why 380V+N is so nice
03:01 PM MrHindsight: Wolf__: how far are you from the poles with 3p?
03:01 PM fragalot: run heavy machinery off of that (or even just your kitchen furnace), and put phase+N to each power socket to get 240V for your everyday appliances
03:01 PM Wolf__: shop is about 300 feet
03:01 PM Wolf__: poles are in my yard
03:02 PM MrHindsight: Wolf__: they typical answer is "you pay for the transformer and the new drop"
03:02 PM MrHindsight: so ~$10-15k
03:02 PM Wolf__: yup
03:03 PM Wolf__: good thing I own a trencher
03:03 PM MrHindsight: lowest cost is transformer drop to the lower part of the pole...
03:03 PM MrHindsight: to the meter
03:03 PM MrHindsight: then you run your own wire on your property
03:03 PM Wolf__: permit + panel install is the $$$
03:03 PM fragalot: don't you need a sub-pole too now, MrHindsight ?
03:04 PM MrHindsight: fragalot: dpends on if he is going to go over or under ground to his shop
03:04 PM MrHindsight: Wolf__: yeah , how many amp service?
03:05 PM fragalot: he's looking for a crane. I'm guessing underground :D
03:05 PM Wolf__: ^ lol
03:05 PM Wolf__: no idea, this would be after new shop built
03:06 PM fragalot: Wolf__: moar is better.
03:06 PM MrHindsight: 200A 3p meter and panel ~$1000 for a permit and licensed contractor
03:07 PM MrHindsight: then whatever else from meter or panel to shop
03:07 PM MrHindsight: panel/disconnect
03:08 PM MrHindsight: fragalot: the power co's get all sorts of leway compared to what you have to do for overhead runs after the meter
03:09 PM fragalot: yup
03:10 PM Wolf__: I have a few other things that need to be done first, addition on house, new meter and underground run for that, have property zoned commercial, build new shop
03:10 PM MrHindsight: oh lots of fun for you
03:11 PM Wolf__: new driveway for sure
03:11 PM * JT-Shop is glad he lives on a dead end dirt road off of a dirt road with no permits or zones
03:12 PM Wolf__: permits needed because electric co wont do any meter work without it =/
03:13 PM Wolf__: I think they might get mad if I did that stuff myself
03:13 PM JT-Shop: the coop just handed me a meter base and said call when your ready for power
03:15 PM Wolf__: lucky
03:17 PM MrHindsight: JT-Shop: one of the advantages to the boonies
03:19 PM MrHindsight: JT-Shop: your area was featured on a recent episode of Vice
03:19 PM MrHindsight: the nail plant and the aluminum plant
03:21 PM {HD}: Wow the grbl_laser pp wasn’t very good
03:22 PM {HD}: There is dwell for laser. Wth flatcam
03:33 PM JT-Shop: the nail plant is in the industrial park south of town, the aluminum plant is over by the Mississippi river
03:33 PM JT-Shop: after the staking engineer left I moved the stakes lol
03:56 PM Roguish: JT-Shop: how are the chicks doing?
04:03 PM Deejay: gn8
04:22 PM enleth: oh man, the fun with the US power system again
04:25 PM enleth: every time this comes up I wonder how is it possible that here, in a former soviet puppet state shithole, pretty much any building that isn't a doghouse or a port-a-potty either has or can easily get a 3x400V service
04:41 PM JT-Shop: Roguish: they have a birthday Thursday and of course they are spoiled
04:54 PM {HD}: Flatcam is dead to me.
05:29 PM {HD}: Wolf__: does laser web beep when I has completed? I don’t have speakers on this machine but if it did beep I go find some speakers.
05:29 PM Wolf__: nope
05:30 PM {HD}: Suck
05:35 PM Wolf__: if your controller has a extra relay, hook 12v to it and a car alarm siren, put gcode trigger at end of file =P
05:39 PM SpeedEvil: Or do a plunge cut into a M80
05:41 PM Wolf__: laser is kinda quiet doing plunge cuts
05:41 PM Tom_L: {HD}, does sheetcam work for that?
05:41 PM Tom_L: likely not
05:41 PM Wolf__: m80 might work tho =D
05:42 PM Tom_L: JT-Shop, did you aim your cannon at the stakes after you moved them as a dare?
05:43 PM {HD}: Nice! ignight firecracer when complete...That is a good feature.
05:43 PM {HD}: I haven't read anything about sheet cam.
05:43 PM Tom_L: well it may be an option, i'm not sure
05:43 PM {HD}: Wolf__: Look at this: https://github.com/a7hybnj2/KicadStuffs/blob/master/Issues%20I%20have%20been%20having/180813/6M6A3042.JPG
05:44 PM {HD}: That is gcode from flatcam that is path follow. So, if you look at the circles the ends are not at the same Y
05:44 PM {HD}: So, somthing is wrong with something...
05:44 PM Tom_L: the fat lines look good, the skinny ones look crooked
05:45 PM Tom_L: why are you laser etching a pcb anyway?
05:45 PM {HD}: Tom_L: The fat lines were a different test. The fat lines in that pic are the multipass + the follow-path.
05:45 PM Tom_L: backlash on your axis?
05:46 PM {HD}: Tom_L: I tried to measure any backlash yesterday with my dial indicator and there was none registering.
05:46 PM {HD}: I could jog out and back to the same exact spot.
05:46 PM {HD}: in both axis
05:48 PM Tom_L: does the laser char the FR4?
05:49 PM Wolf__: wonder if its due to the output being more like steps vs smooth circular interpolation?
05:50 PM Wolf__: paint board, laser off the paint, etch?
05:50 PM {HD}: Tom_L: I am burning away a spraypaint mask to expose the copper to etch.
05:50 PM Tom_L: oh
05:50 PM {HD}: So I havent hit the exposed fr4 with a laser yet.
05:51 PM {HD}: Wolf__: any thoughts on how to test that? Manually write up a gcode circle?
05:51 PM Tom_L: look at the gcode
05:51 PM Wolf__: no idea, use lcnc control + better cam post?
05:52 PM Tom_L: if it's line segments change it to circles
05:52 PM Wolf__: I dunno if the gbrl will do circles
05:52 PM Tom_L: it should
05:52 PM Tom_L: it's a very basic gcode move
05:52 PM Wolf__: ok
05:52 PM Wolf__: I know {HD}’s nc file is all x/y with no interpolation code
05:53 PM Tom_L: G0, G1, G2, G3, G38.2, G38.3, G38.4, G38.5, G80
05:53 PM Tom_L: in that modal group
05:54 PM {HD}: Interesting.
05:54 PM Tom_L: https://github.com/gnea/grbl/wiki/Grbl-v1.1-Commands
05:56 PM {HD}: Nice. So I will just code a gcode circle with a 3mm dia
05:57 PM Wolf__: that https://i.imgur.com/ImYAA3e.jpg is ~4000 lines of gcode….
05:57 PM Tom_L: add 2 sticks protruding from it
05:58 PM Tom_L: should be about 28 lines
05:58 PM Tom_L: maybe 30-32 with the preamble code
05:58 PM Wolf__: 8 lines per pass on the most complex
06:01 PM Tom_L: how much stepover do you need on a laser?
06:03 PM {HD}: I am still dealing in my settings but I am estimating my laser diameter to be .075 mm. And I’ve been using a50% overlap.
06:04 PM Tom_L: do you call up a tool number for it or just run the code?
06:04 PM Tom_L: i'm used to mill & lathe code
06:05 PM {HD}: I just run the code.
06:05 PM Tom_L: i wonder if i have a laser post for my cad cam
06:05 PM Tom_L: i doubt it
06:06 PM Tom_L: even more so i wonder where the heck i put them all
06:06 PM {HD}: Can I just G00 X10 Y10, G02 I5, done?
06:07 PM Tom_L: for what?
06:07 PM Tom_L: G00 is a rapid move
06:08 PM Tom_L: you need G03 or G03 with X Y I & J
06:08 PM Tom_L: XY iirc is the arc center and I J is the endpoint
06:09 PM Tom_L: I J correlate to X and Y
06:16 PM Tom_L: G2 X0.0, Y0.0, I-0.5, J0.0
06:17 PM {HD}: https://i.imgur.com/uNHBTBn.jpg
06:17 PM Wolf__: once you figure it out https://i.imgur.com/B5uhafo.jpg works well
06:18 PM {HD}: Dang!
06:18 PM Tom_L: no, you need x y i j for G2
06:19 PM {HD}: Well I haven’t found a good resource yet then. Because what I just read said what I just wrote should work
06:19 PM Tom_L: you drew that with your spiralgraph and a pencil :D
06:19 PM Wolf__: I think I used the arc gen script in lcnc to learn it
06:19 PM {HD}: Tom_L: what is J
06:19 PM Tom_L: the Y coordinate for the endpoint of the arc
06:19 PM Tom_L: I is the X coordinate for the endpoint of the arc
06:20 PM Wolf__: https://i.imgur.com/j52xZPn.jpg =p
06:20 PM Tom_L: X & Y are the arc center
06:20 PM {HD}: If you’re doing arcs. What if you’re doing circles?
06:20 PM Tom_L: a circle is a full arc

06:22 PM {HD}: Sob! Windows just crashed! I’ve never had that happen before! “Driver_IrQL_not_less_or_equal“
06:26 PM Tom_L: the example i posted was a 1" circle with 0,0 as the centerpoint
06:27 PM Tom_L: depending on G20 / 21 setting
06:30 PM {HD}: Hum. Still nothing. Gotta try something else.
06:32 PM {HD}: Its gotta be something with laserweb...
06:33 PM Wolf__: laserweb kinda sucks for MDI, just serial connect to the gbrl
06:33 PM MrHindsight: enleth: capitalisim and guberment granted monopolies is why
06:33 PM Wolf__: it does some weird stuff to outgoing command line stuff
06:35 PM Tom_L: what is lasergrbl?
06:35 PM Tom_L: have you looked at it?
06:36 PM Wolf__: dunno
06:37 PM Wolf__: I’m using smoothie with general cnc firmware
06:37 PM Tom_L: what laserweb version are you running?
06:37 PM {HD}: 4
06:37 PM Wolf__: no idea here lol
06:37 PM {HD}: But I just used universal G code sender.
06:38 PM {HD}: And I got a good looking circle as output.
06:38 PM Tom_L: what do you use to load the gcode?
06:39 PM {HD}: My G code is trickle fed to the Grbl via laser web or universal Chicod sender
06:39 PM {HD}: S/Chicod/gcode
06:39 PM Tom_L: what i should have asked is what generates the gcode you send
06:41 PM {HD}: For the gerber pcb stuff I have been trying to use flatcam. I was using pcb2gcode but it has a bug that prevents my current project from working.
06:42 PM Tom_L: have you looked at inkscape?
06:43 PM {HD}: Yes. I have inkscape loaded.
06:43 PM Tom_L: i've never used it for gcode but some have
06:43 PM {HD}: I tried the G code extensions but did not get what I was expecting.
06:44 PM {HD}: https://i.imgur.com/LK3NyGD.jpg
06:44 PM {HD}: That’s the output from ink scape
06:45 PM Tom_L: wow that's awesome :)
06:47 PM {HD}: So, I just loaded the same code into laser web and it did cut a circle. However it does not show a circle in the G code viewer to be cut.
06:47 PM {HD}: So it must have a bug with rendering G2 moves
06:50 PM {HD}: Anyway its dinner time. Will be back at it later.
07:56 PM {HD}: So, Seems like the issue is with the cam software. That stinks. That being said it is still almost ok and would probabley be fine for testing.
