12:04 AM Crom: 2 hrs....
12:08 AM cncnoob: Hey guys, I'm having trouble getting my first program to run (still). Been working on it almost every night now for 2 weeks after setting my first machine (3 axis milll)
12:08 AM cncnoob: The gcode commands the tool to go to zero on the z axis at the start of the program
12:08 AM Crom: what kinda problems you having?
12:08 AM cncnoob: but even after I have touched off it thinks I'm exceeding the machine maximums on the z axis
12:09 AM cncnoob: LinuxCNC tells me which lines are having troubles, but I just can't understand why
12:09 AM MacGalempsy: is your zero point origib set correctly?
12:09 AM MacGalempsy: in the CAM
12:09 AM Crom: that sounds like a config problem... what ranges did you use in stepconf?
12:10 AM cncnoob: I think so? I have the origin set to the top left of the stock in my CAM
12:10 AM XXCoder: cncnoob: you sure you set machine size correctly?
12:10 AM cncnoob: In linux CNC the machine size is absolutely correct
12:10 AM XXCoder: because if it think its smaller than it really is, and pathway goes outside bounds it will ask that
12:11 AM cncnoob: I have homing switches, limit switches, and soft limits are all working well
12:11 AM XXCoder: look at program graphics, is some of it sticking outside bounds?
12:11 AM MacGalempsy: also with that error it could be ramping in to the workpiece
12:12 AM cncnoob: XXCoder, that is one weird part. Before I start the program I touch off (touch off, not tool touch off). The tool paths are within the bounds of the red box
12:12 AM cncnoob: but when I start the program the tool paths move up outside of the box
12:12 AM XXCoder: hm maybe its setting machine homes or some strange stuff like that
12:12 AM MacGalempsy: do you have the tool length offset set properly?
12:12 AM XXCoder: or that
12:13 AM cncnoob: Even stranger, when I remove the stock and virtually bottom the z axis (9 inches of travel) and the tool paths remain in the box, I get the same error
12:13 AM cncnoob: In my CAM I have the tool lengths and holders set
12:13 AM cncnoob: I'm using Camworks and I measured every bit and holder I have
12:13 AM Crom: sounds like it's the absolute positioning problem
12:13 AM MacGalempsy: all the way up is zero and down will be negative. is that what happens on your machine?
12:14 AM cncnoob: G43 Z1. H01
12:14 AM cncnoob: that the first line it complains about
12:14 AM XXCoder: you have to set tool lengths on machine lso
12:14 AM XXCoder: er linuxcnc
12:14 AM cncnoob: Another line is Z5.
12:15 AM cncnoob: Doesn't tool offset do that in linuxcnc?
12:15 AM cncnoob: sorr
12:15 AM cncnoob: tool touch off is what i ment
12:15 AM MacGalempsy: read up on cutter comp and tool table. that should help
12:15 AM cncnoob: guess I'm a little confused on those too, when to use touch off vs tool touch off
12:16 AM Crom: cncnoob, if absolute position goes out of range it'll error as well
12:17 AM Crom: in stepconf you could try making Z range be -20" to 20" plus if your Z actual range -9" to 0"
12:17 AM MacGalempsy: touch off is telling lcnc where the zero point origin is located. where the program starts. tool touch off sets the tool length
12:19 AM Crom: you should home at 0 (top 0.5") and then set touch off. so your absoulte Z position is within range
12:19 AM XXCoder: make sure to dry run to make sure code is sane with that also heh
12:19 AM Crom: top -1" or -0.5 for absolute Z zero.
12:19 AM cncnoob: Yeah my home is top 0 but closer than 0.5".
12:20 AM MacGalempsy: what is down?
12:20 AM Wolf_: wait, you Z axis at 0 is only 0.5 over the work?
12:20 AM Crom: I have my Z home switch at
12:20 AM Crom: I have my Z home switch at +5mm then home at 0
12:21 AM Crom: then I touch off on work for my work zero
12:21 AM cncnoob: I have z axis home at 0 and I have another 0.005 of travel up
12:21 AM cncnoob: my max limit is set at 0.001 and my min limit is set at -9.820
12:22 AM Wolf_: how much travel down to the work from absolute 0 ?
12:22 AM cncnoob: wolf, you mean from home?
12:22 AM cncnoob: with a tool in?
12:22 AM Crom: nice range... Grizzley or harbor freight mill?
12:22 AM XXCoder: mine is simple lol I get close to home position, turn off steppers and manually move it to approx home, turn steppers on set home
12:22 AM cncnoob: hf
12:22 AM Wolf_: may have to check the cam processs to make sure its not calling for a 10” rise before travel
12:23 AM cncnoob: wolf, let me take a screen shot real quick and maybe you can see if that is what is happening
12:23 AM cncnoob: there are pink lines on lcnc that are outside the red box
12:24 AM Wolf_: axis screen won’t tell much of anything, just need to read the gcode
12:24 AM cncnoob: ah
12:24 AM cncnoob: ok, well I'll paste bin it
12:24 AM cncnoob: or wait
12:24 AM cncnoob: what is the max number of lines here again?
12:24 AM XXCoder: 2 or 3
12:24 AM cncnoob: haha
12:24 AM cncnoob: ok
12:24 AM XXCoder: dpaste.com it
12:25 AM Wolf_: just look at the code, first line with a G0 Z with positive number lol
12:26 AM Wolf_: hmm not to scary, laser mess $974 + $490 DHL shipping
12:27 AM Crom: Which laser? K40's for around $350 or so
12:28 AM Wolf_: 100W RECI tube, psu and all the belt drive parts and mirrors/mounts
12:28 AM Crom: nice! the K40 35w tube is crap tacular
12:29 AM Crom: the 20x30cm work area blowz too
12:29 AM Wolf_: I was going to get a red box ebay special but I hear those are even worse
12:29 AM Wolf_: “100w” tube, does like 75w
12:29 AM cncnoob: http://pastebin.com/0WDFuH6d
12:29 AM Crom: but I have 2 of them
12:29 AM roycroft: are you guys still talking about lasers?
12:29 AM roycroft: one of you is gonna put his eye out, you know
12:29 AM cncnoob: my program uses two tools
12:29 AM Wolf_: somewhat, roycroft… just got quote back from aliexpress
12:30 AM cncnoob: I pasted up to the first and only tool change
12:30 AM cncnoob: I didn't see a G0 Z line
12:30 AM Crom: line 11... Z1 is what in absolute positioning?
12:31 AM cncnoob: what do you mean
12:31 AM cncnoob: "is what in absolute positioning"
12:31 AM Wolf_: G43
12:32 AM cncnoob: should that be a g54?
12:32 AM Wolf_: no G43 is tool table offset
12:32 AM Crom: if home z is 0 and touch off is 0, then Z1 is out of range. If Z is homed at 0 and touch is Z -6,75 then Z1 working == Z-5.75 absolute
12:32 AM XXCoder: G90 G54 G00 X1.715 Y1.2
12:33 AM cncnoob: my bad, yeah that was a dumb question
12:33 AM XXCoder: crom yeah its still on g90 at that point where it moves to +1
12:33 AM cncnoob: I think all the coordinate systems are G5* except G92 right (a lot to remember)
12:33 AM Crom: there is your working coordinates (touch off) and absolute position
12:34 AM MacGalempsy: cncnoob you should study up on the getting started manual. it goes thru all this
12:34 AM cncnoob: Crom, you mean the line XXCoder pasted?
12:35 AM XXCoder: g90 is absolute position
12:35 AM XXCoder: since it is last mode set before z1 it causes it to try to go up one inch poast top
12:35 AM XXCoder: while if g91 it would move one inch up which sounds correct.
12:35 AM Wolf_: G43 isn’t a move command
12:36 AM XXCoder: ah missed that. yea
12:36 AM cncnoob: So this sounds like something I need to change in camworks some how
12:36 AM Wolf_: but the syntax is wrong on the G43 also lol
12:36 AM Crom: I'm not sure of the commands... I use MDI in linuxcnc and the touch off button before I run a g code file
12:37 AM Wolf_: G43 without an H word uses the currently loaded tool from the last Tn M6.
12:37 AM Wolf_: G43 Hn uses the offset for tool n.
12:37 AM cncnoob: It is slightly aggravating that I can run this in camotics and in the camworks sim and neither have a problem
12:37 AM XXCoder: Wolf_: wouldnt it default to last move mode when coord is given without g0 g1 so on move command?
12:38 AM XXCoder: looking at code g0 is last movement gcode
12:38 AM Wolf_: I dunno, my cam gives me correct code :P
12:38 AM Wolf_: never tried something like this example lol
12:38 AM XXCoder: hmm dunno also.
12:39 AM cncnoob: what cam do you use?
12:39 AM XXCoder: I use image to gcode for now sadlu
12:39 AM XXCoder: trying to figure what to do for cam at this time. usually hand code or image to gcode.
12:39 AM Wolf_: I use some pita stuff hooked to SW
12:39 AM Crom: inkscape or heekscam fusion 360 once in a while
12:39 AM cncnoob: fusion 360 is awesome I hear
12:39 AM XXCoder: crom about inkscape is there examples on that?
12:40 AM cncnoob: but I already knew solidworks when I decided to make my own CNC mill so...
12:40 AM XXCoder: if video, hopefully captioned
12:40 AM Wolf_: I’m going to move over to fusion but need to new laptop first
12:40 AM XXCoder: im considering reinstalling windows on my ye olde laptop
12:40 AM XXCoder: windows xp ok for fusion?>
12:40 AM Wolf_: yeah
12:40 AM Wolf_: need grunty vid card tho
12:40 AM cncnoob: good thing about fusion when compared to solidworks (other than being free) is that it doesn't require workstation graphics
12:40 AM XXCoder: its so old it dont have wifi built in, has to use dongle lol
12:41 AM MacGalempsy: whats the next step on you laser Wolf_?
12:41 AM cncnoob: it is optimized to work with desktop graphics cards
12:41 AM MacGalempsy: desighn to self build
12:41 AM Wolf_: MacGalempsy: spending $$$$ lol
12:41 AM XXCoder: I lost the PMCIA wifi card.
12:41 AM MacGalempsy: ahhh. snapple. thats no good!
12:42 AM roycroft: pcmcia is so last millenium
12:42 AM XXCoder: 2003 laptop actually
12:42 AM XXCoder: late 2002 more like
12:42 AM MacGalempsy: vintage is good.
12:43 AM roycroft: vintage is vintage
12:43 AM roycroft: it can be good and it can be bad
12:43 AM XXCoder: mac it actually has parallel port LOL
12:43 AM MacGalempsy: get everything you can from it
12:43 AM XXCoder: but it bombed the jitter test
12:43 AM XXCoder: 250k
12:43 AM Crom: I have a vista hp pavillian DV4 old... quadcore though
12:43 AM MacGalempsy: sweet! one of these days ill repair this apple 3400c laptop
12:44 AM Crom: my stinkpad has a flakey wifi.... grrrr
12:44 AM MacGalempsy: my grandparents brought over a 386 clone and dropped it off. they couldnt bear tossing it. (circa 1994)
12:44 AM Crom: still looking for a stable usb wifi for it
12:45 AM XXCoder: stinkpad lol
12:46 AM MacGalempsy: heh. does it have the mouse nub in the middle of the keyboard?
12:46 AM Crom: oops the HP is dual core... the itx linuxcnc machine is a quad core as well as the stinkpad
12:46 AM Crom: yep
12:47 AM Crom: never use it though
12:47 AM MacGalempsy: i always thought that was cool
12:47 AM XXCoder: eraser lol never had laptop with that
12:48 AM Wolf_: MacGalempsy: got laser web setup on old laptop, a X5 GT board running smootieware ordered, just need to start the frame design and order the tube/psu/optics
12:48 AM MacGalempsy: me neither. could never afford a laptop when that came out
12:48 AM XXCoder: my most favorite is acer aspire one
12:48 AM XXCoder: its one of earliest linux laptop, and first ssd one
12:49 AM XXCoder: 4 gb ssd hd heh
12:49 AM MacGalempsy: Wolf_ still aiming to cut plywood?
12:49 AM Wolf_: yup
12:49 AM MacGalempsy: how thick?
12:49 AM Wolf_: if I can cut 1/2” ply I’ll be happy
12:50 AM Wolf_: even 3/8 wouldnt be bad
12:50 AM MacGalempsy: 4x8 sheet?
12:50 AM Wolf_: not all at once lol
12:51 AM cncnoob: So G90 is absolute distance mode
12:51 AM MacGalempsy: next step is booking craft show spaces
12:51 AM cncnoob: why is there a g54 immediately after it on the same line?
12:51 AM XXCoder: cnc yep if 0, it goes to machine 0
12:51 AM cncnoob: http://linuxcnc.org/docs/html/gcode/g-code.html#gcode:g90-g91
12:51 AM XXCoder: g54 changes coord system from g53 (machine) to g54 (coord 1)
12:52 AM cncnoob: I'm having a hard time breaking down lines 10 - 12
12:52 AM MacGalempsy: make some plywood flowers and signs thaf say "eat"
12:53 AM MacGalempsy: etch some stainless coffee cups
12:53 AM cncnoob: so in my cod the g90 g54 is saying "move some absolute amount relative to the workpiece"?
12:53 AM cncnoob: Is that correct?
12:53 AM cncnoob: How about that G00
12:54 AM cncnoob: I don't see a reference to it on the wiki
12:54 AM cncnoob: only G0
12:54 AM MacGalempsy: g5000 yo
12:54 AM XXCoder: g0 anf g00 is same
12:54 AM cncnoob: ok cool
12:54 AM XXCoder: g0 is just rapid
12:54 AM XXCoder: depending on controller g01 and g1 is same usually for example. linuxcnc it is the case
12:55 AM Crom: G00 == G0 same thing
12:55 AM cncnoob: this is only slightly easier that debugging assembly
12:55 AM cncnoob: We need some python based movements!
12:56 AM XXCoder: asm I love that one. though yeah hard to read LOL
12:57 AM Crom: I strip out the G90, G92 and G5[4-9] stuff...
12:58 AM Wolf_: MacGalempsy: actually I was thinking about just finding some people that already do shows like that to sell shit to :)
01:00 AM Crom: cncnoob change your Z home to 0 but have it down from the top -1.005" and have your Z be range -8.82 to 1.001
01:01 AM cncnoob: Yeah, that would work for this program, and actually I can get it to cut if I take the swivel off my vice. I really want to "fix it right" though so I can generate any gcode and easily run it
01:01 AM cncnoob: for any part that would physically fit on my machine that is.
01:01 AM MacGalempsy: Wolf_ that would be ideal, but hanging out on a Saturday would make more $$$. One of my inlaws does it every weekend and she makes $$$
01:02 AM Wolf_: what, doing cut to order on site?
01:02 AM XXCoder: cncnoob: check your cam for tool set gcode, maybe its set to move upwards one inch
01:02 AM MacGalempsy: no she sells cow skins! lol
01:02 AM XXCoder: not familiar with your cam so dunno what form it would show up as.
01:03 AM Wolf_: I might look in to that, but this build isn’t going to be very portable when its done
01:03 AM MacGalempsy: but go to a show or two and you'll get some great sales ideas. however you'll cringe at the thought of putting it in your own home
01:04 AM Wolf_: if I was building a little 50-60w unit doing shows wouldnt be bad
01:04 AM cncnoob: ok thanks guys, I'll look into my CAM some more to see why it is generating what it is generating. I'm so close to making chips!
01:04 AM roycroft: wow
01:04 AM roycroft: https://eugene.craigslist.org/tls/6028094487.html
01:04 AM MacGalempsy: her bro wants a plasma table to make kitchen signs they buy them now, but making them would increase the profit
01:05 AM roycroft: people dump those off at the goodwill, and the goodwill sells them for $35
01:05 AM MacGalempsy: lol. its custom!
01:05 AM roycroft: it's blue!
01:06 AM MacGalempsy: vintage, its made w real metal
01:06 AM roycroft: if i could sell those for $650 i'd buy as many as i can get at the goodwill and start spraying blue paint
01:06 AM roycroft: yes
01:06 AM XXCoder: cncnoob: I got something for you to try meanwhile heh
01:06 AM roycroft: that exact same desk is what i can buy for $35 every day of the week
01:06 AM MacGalempsy: they are heavy as hell
01:06 AM roycroft: and this is a case where vintage *is* good
01:06 AM cncnoob: @xxcoder what is that?
01:06 AM MacGalempsy: and good luck getting them thru a standard doir
01:06 AM roycroft: but good does not have to be expensive
01:07 AM XXCoder: cnc a sec trying to find uit
01:07 AM MacGalempsy: oh. get one and cnc plasma out 90% of the structure
01:07 AM Crom: and they have good formica on the top too...
01:08 AM MacGalempsy: yeah. writing on those with a ballpoint is great
01:08 AM XXCoder: cncnoob: https://static-2.gumroad.com/res/gumroad/5387571460549/asset_previews/ea0c5e84f29b3706697ed47039d7a930/retina/Earth_2k_Disp_Preview_v001.jpg
01:09 AM XXCoder: use linuxcnc image to gcode
01:09 AM XXCoder: black is deepest white is highest
01:10 AM MacGalempsy: make a cnc that mounts onto the desk and custom etch the top
01:11 AM MacGalempsy: company logo, world map, nudies, etc...
01:11 AM XXCoder: also tried http://web.borisfx.com/helpdocs/wp-content/uploads/2013/06/dispmap.map_.original1.jpg looked good lol
01:14 AM MacGalempsy: you can get DEM from the usgs for anywhere in the US
01:14 AM XXCoder: LOL I so want to try thios. https://3.bp.blogspot.com/-I6dlLYOghqA/T4xjnwYVVyI/AAAAAAAAAd8/-VmQl0GB2qk/s1600/displacement2.jpg
01:15 AM XXCoder: make it to small size, see what happens. I do have nice 1/16 ball em
01:18 AM XXCoder: https://www.youtube.com/watch?v=8kfNAhM_NLg inkscake as cam
01:22 AM Wolf_: MacGalempsy: I thought about doing just that to the desk top for my main computer desk, planning on doing epoxy coat to MDF, realized when I’m playing with the frame and tube I could laser engrave the top and do a color fill w/ clear top coat :)
01:24 AM MacGalempsy: that would be neat
01:24 AM cncnoob: @xxcoder I'm guessing I should use a pretty small bit for that?
01:24 AM Wolf_: but knowing how things go, I’ll probably do my first plan on the desktop, which was just west system epoxy w/ automotive metal flake mixed in
01:24 AM cncnoob: how small would you recommend?
01:24 AM cncnoob: I only have flat end mills right now
01:25 AM XXCoder: cnc yep
01:25 AM XXCoder: bigger the area can do with bigger tool
01:25 AM XXCoder: but smaller the better details
01:26 AM cncnoob: did you just pause the program in the middle and change to a smaller tool?
01:26 AM Crom: cncnoob, your mill is an R8 right?
01:26 AM cncnoob: yes
01:26 AM XXCoder: it dont change tool really
01:26 AM XXCoder: corner is lower left of image, and tool you just touch tool on surface to be engraved
01:26 AM cncnoob: I have a 0.0197 loaded right now
01:27 AM Crom: get a 3/4" R8 collet for TTS
01:27 AM cncnoob: what is TTS?
01:27 AM XXCoder: I didnt bother with tool length just set part coord where tool touches part
01:28 AM cncnoob: ok, doing it now with 0.0197 flat end mill :D
01:28 AM Crom: then you can start colleting TTS tool holders ER32 ER25 1/2" 3/8" 1/4" endmill holders
01:28 AM XXCoder: I have 2 of all metric collets lol I was orginially using shitty grinder as spindle, but later bought spindle, it come with its own set
01:29 AM cncnoob: I have several end mill holders now, but eventually I want to make a power tool changer so I will make some tool holders
01:29 AM cncnoob: Need to get my first program running first though :/
01:29 AM XXCoder: cnc careful on plunge since flat endmills dont like that lol
01:30 AM XXCoder: on my tiny ball em I used 100 mm/m on plunge and 1000 mm/m for cutting speed
01:30 AM Crom: I'm running a 400w DC spindle with ER11 collets bunch of 2mm 3mm 4mm and 1/8" end mills and a couple 1/4" which is doesn't like at all
01:37 AM Deejay: moin
01:37 AM XXCoder: hmm interesting
01:38 AM XXCoder: just made first gcode using makercam
01:39 AM Crom: makercam that's the web based one?
01:42 AM XXCoder: yeah
01:42 AM XXCoder: used washington svg file
01:43 AM XXCoder: https://www.youtube.com/watch?v=szXNpI4GydA my machin
01:44 AM cncnoob: @xxcoder, so I get the same error I was getting with my program using the image you linked to, but for minimums instead of maximums
01:45 AM XXCoder: oh did you set tool length to 0? youre setting z coord with tool end after all
01:45 AM cncnoob: there is a long cyan line running out of the red bounding box in axis
01:46 AM XXCoder: oh thats weird
01:46 AM XXCoder: cncnoob: https://www.youtube.com/watch?v=1JMSRF6Q9uw my machine btw
01:47 AM XXCoder: its dry running, there is later videos of it cutting stuff
01:47 AM cncnoob: sounds like R2D2
01:47 AM XXCoder: well thats cool I guess lol
01:48 AM cncnoob: haha
01:48 AM cncnoob: yeah
01:48 AM XXCoder: im deaf so I dont know how it sounded like, thats why I made video
01:48 AM cncnoob: https://www.youtube.com/watch?v=bID5QB74Vjk
01:48 AM cncnoob: other things that sound like r2d2
01:49 AM XXCoder: so people can check sounds if good. you should listen to previous videos it was apparently bad
01:51 AM XXCoder: https://www.youtube.com/watch?v=5LTTuFjYc0I old electrics system.
01:51 AM cncnoob: so that cyan line in axis is my g54 line I believe
01:51 AM cncnoob: something is weird here
01:51 AM cncnoob: my z axis has 9.8" of travel
01:51 AM XXCoder: https://www.youtube.com/watch?v=kZXK1ljoxF8 engraving pengin heh
01:51 AM cncnoob: the top of the stock is exactly 4.5" from the table
01:52 AM cncnoob: but looking at the image in axis from the y axis perspective the bulk of my machine's travel is at the bottom of the stock
01:52 AM XXCoder: still think its machine configuration problem, for cam
01:53 AM cncnoob: I think I might have multiple problems
01:53 AM XXCoder: possibly
01:53 AM XXCoder: btw that first junky machine I linked to was a joke, its someone else dunno who
01:55 AM Crom: that was kewl!
01:56 AM cncnoob: https://imagebin.ca/v/3EbUEbWJuT7e
01:56 AM cncnoob: I figured as much
01:56 AM cncnoob: After you sent the second link that is :)
01:57 AM XXCoder: man thats faaaar out
01:57 AM * XXCoder takes huff of bowl
01:58 AM cncnoob: any ideas?
01:59 AM XXCoder: not at this time unfortunately
01:59 AM XXCoder: Z11.22 g54 z
02:00 AM XXCoder: you sure you set g54 coord of part correct spot?
02:00 AM XXCoder: typical is top of part stock
02:00 AM Crom: -11.2270? sheeshz
02:02 AM cncnoob: I put in my bit and set it right on top of the stock then pressed the touch off button
02:03 AM cncnoob: then height of that cyan line looks to be exactly the height of my bounding box
02:03 AM Crom: z home still looks funky
02:04 AM XXCoder: hmm any error this time?
02:09 AM XXCoder: hopefully youre cutting a lot of air chips now lol
02:10 AM cncnoob: ok i just restated axis
02:11 AM cncnoob: The first time I touched off I then moved z all the way up
02:11 AM cncnoob: Maybe I shouldn't have done that
02:11 AM cncnoob: this time I pressed play immediately after touching off all axises
02:11 AM cncnoob: and it started moving
02:11 AM XXCoder: always start it off SLOW when starting a unproven program
02:12 AM cncnoob: The first thing it did was move all the way to the back of my stock (top of the pic)
02:12 AM cncnoob: how do you start it slow?
02:12 AM XXCoder: use feed rate slider there
02:12 AM cncnoob: ah yes
02:12 AM cncnoob: well
02:12 AM cncnoob: that would have saved me a bit!
02:12 AM XXCoder: its set to 100%, I usually ser 10%, ramp it up as I know its not fucking up.
02:12 AM Wolf_: or use something softer then the mill bit
02:12 AM Wolf_: like a block of foam
02:12 AM cncnoob: I have a piece of wood in there now
02:12 AM XXCoder: Wolf_: nothing softer than air
02:13 AM cncnoob: I cut the wood to the size of the pink box
02:13 AM cncnoob: it said 6.09 x 2.95
02:13 AM Wolf_: lol yeah, but you can’t tell if the depth is correct air cutting
02:13 AM cncnoob: but the first move put the bit completely off the stock
02:13 AM XXCoder: Wolf_: yeah thats not point of dry run, its point is to see if gcode is sane at all, if it was newly made
02:13 AM cncnoob: my stock is 3"x 6.25
02:14 AM Wolf_: does your code still have that g28 in it?
02:14 AM XXCoder: cncnoob: so whats your setup process after you place stock and turn machine on?
02:14 AM Wolf_: nm g28 is just go to command
02:15 AM XXCoder: setting home and part coord?
02:15 AM cncnoob: one sec
02:15 AM cncnoob: uploading image
02:16 AM cncnoob: https://ibin.co/3EbaKO7NcXL7.png
02:17 AM XXCoder: looks more usual
02:17 AM cncnoob: For cutting the image you linked to I first put the stock in the vise and then moved the all axises to the bottom left corner of the stock
02:17 AM cncnoob: I then touched off on each axis
02:17 AM cncnoob: I then pressed play
02:17 AM XXCoder: how do you set machine home? its automated with switches?
02:17 AM cncnoob: What size stock would you expect I would need based on that pic?
02:17 AM arekmx is now known as arekm
02:17 AM Wolf_: can ya bin the code again?
02:18 AM XXCoder: 7.81x3x1.73 of unknown units
02:18 AM cncnoob: Yeah, one sec (different code this time)
02:18 AM cncnoob: inches
02:18 AM XXCoder: you can see numbers on red bars it shows size of cut area
02:18 AM XXCoder: use 3d view to see how deep it will cut
02:19 AM XXCoder: and make sure it dont hit say jaws or something
02:19 AM Wolf_: I plan that when I’m doing cam op :)
02:19 AM cncnoob: http://pastebin.com/bnbp724N
02:20 AM XXCoder: is that from image to gcode?
02:20 AM cncnoob: what are the 6.09 and 2.09?
02:20 AM cncnoob: yes
02:21 AM Wolf_: lets see, cut starts at X -0.1189
02:21 AM Crom: that looks better
02:21 AM XXCoder: 6.09 is cuts length, 2.95 is Y length of cuts, 1.73 is height
02:21 AM XXCoder: can you do 3d view screenshot?
02:21 AM Wolf_: ends at X 5.9640
02:21 AM XXCoder: the P icon top right near sweeper
02:22 AM Crom: hunk of 2x4 would do it
02:22 AM Wolf_: cam this as a facing op?
02:22 AM Crom: nite nite
02:22 AM XXCoder: wolf think its image to gcode like I did in my video
02:22 AM cncnoob: https://ibin.co/3EbcN9GqKZ4T.png
02:23 AM Wolf_: oh ok
02:23 AM cncnoob: by crom
02:23 AM XXCoder: mill? because lol your z is so tall comared to mine
02:23 AM cncnoob: thanks for your suggestions
02:23 AM XXCoder: no problem :D
02:23 AM XXCoder: making world map?
02:23 AM cncnoob: trying to!
02:24 AM cncnoob: I need some success
02:24 AM cncnoob: especially since it is like 4 hours past my bed time
02:24 AM XXCoder: you'll like it, I love mine even with my error of "renormalize" that made mountains twice as tall
02:24 AM Wolf_: its using a lead in/out so the cutter movements are bigger then the cut part
02:25 AM Wolf_: but like 1/6” of a inch lol
02:25 AM cncnoob: Ok, I think I need to remount it then
02:25 AM Wolf_: I need to sleep as well, got a AM appointment
02:32 AM XXCoder: hows it oing so far?
02:33 AM Wolf_: ?
02:33 AM XXCoder: *going
02:36 AM Wolf_: hopefully laser tube will be on order before wed
02:36 AM XXCoder: nice :)
02:37 AM Wolf_: $1464 after shipping cost, no idea what the duty $$ will be tho
02:38 AM XXCoder: assume its half of it
02:38 AM XXCoder: then be happy if less
02:38 AM Wolf_: lol
02:39 AM Wolf_: what has me confused is two things, one is somewhere said things under 800 come in duty free, other was the HS code for the laser says it comes in w/ no duty rate
02:40 AM cncnoob: ok chips are being made!
02:40 AM XXCoder: awesome!
02:40 AM cncnoob: or saw dust rather :)
02:40 AM XXCoder: little slow, same as mine.
02:41 AM XXCoder: I plan to try fatser feedrate later see how it goes.
02:41 AM cncnoob: I'm just not familiar with how fast I can go before a bit breaks
02:41 AM cncnoob: how fast did you go last time?
02:41 AM XXCoder: 1000 mm/m
02:41 AM XXCoder: I wish theres bot here to do conversions
02:42 AM XXCoder: ah 423 approx ipm
02:44 AM cncnoob: I was at 20% of 508mm/m and I tried to double it and broke a bit
02:44 AM XXCoder: ow
02:45 AM cncnoob: thankfully HF bits are cheap
02:50 AM XXCoder: so you starting it again?
02:50 AM cncnoob: yup
02:50 AM cncnoob: just started again
02:50 AM cncnoob: at this rate it will be quite some time
02:51 AM XXCoder: yeah. nothing compared to some parts I have ran
02:51 AM XXCoder: 6 hours to make one part fot example
02:51 AM cncnoob: It is about half way done with the first row
02:52 AM XXCoder: depending on what depth you selected it should be just couple passes
02:52 AM XXCoder: horzional, vertical, horzional, then vertical
02:52 AM cncnoob: what depth?
02:52 AM cncnoob: o
02:52 AM cncnoob: oh
02:52 AM XXCoder: layer depth
02:52 AM cncnoob: you mean in the settings
02:52 AM cncnoob: let me check
02:52 AM cncnoob: I took a screen shot
02:54 AM cncnoob: 0.25 is what it says
02:54 AM XXCoder: 1/4 inch per layer
02:54 AM XXCoder: whats total depth?
02:55 AM cncnoob: https://ibin.co/3EbmEmeMQKPO.png
02:55 AM cncnoob: just broke another bit :)(
02:55 AM cncnoob: Think I'm going to call it a night
02:55 AM cncnoob: too much failure for one day
02:56 AM XXCoder: you set type to ballend
02:56 AM XXCoder: it handles it differently with regular em
02:57 AM cncnoob: !@#$
02:57 AM cncnoob: I didn't even see that
02:57 AM cncnoob: Just went with the defaults
02:57 AM cncnoob: oh well, I'll try it again tomorrow when I'm fresh
02:57 AM cncnoob: I'll let it run as I dig in to my cam settings for the part I actually want to make :)
02:58 AM cncnoob: thanks for all your help tonight
02:58 AM XXCoder: no problem
05:12 AM jthornton: morning
05:12 AM XXCoder: hey
05:15 AM SpeedEvil: hey
05:20 AM XXCoder: http://www.instructables.com/id/MicroSlice-A-tiny-Arduino-laser-cutter/ jthornton
05:25 AM jthornton: cool
05:25 AM XXCoder: yeah too bad model files download is broken
05:27 AM jthornton: the pdf zip file downloads for me
05:29 AM XXCoder: so it is
05:29 AM XXCoder: I clicked direct download link above that
06:24 AM Deejay: whoopsie, that was the wrong button ;
08:15 AM [cnc] is now known as [cube]
08:16 AM Longbow: hello
08:17 AM Longbow: I am now trying for the firs time to start a program - axis.ngc on my mill
08:17 AM Longbow: but it stops at line 15: G0 X[1.75781*#<scale>] Y[0.5*#<scale>]
08:17 AM Longbow: I set the tool to T1 M6
08:17 AM Longbow: just for testing
08:18 AM Longbow: it just stops to move
08:19 AM Longbow: it will not execute the line G1 F100.0 Z[-#<depth>]
08:20 AM Longbow: F100...mybe my MAX velocity is too low in the INI file?
08:26 AM JT-Shop: do you have your spindle connected, prob fails one line 14 waiting for spindle at speed
08:27 AM JT-Shop: if your just testing in the air comment out line 14 with a leading ;
08:27 AM Longbow: yeah spindle is OFF because the soft_start wont work
08:27 AM Longbow: I will try with M3 s100
08:28 AM JT-Shop: why?
08:29 AM Longbow: if I leave it to M3 S10000 it will accelerate in a moment
08:29 AM Longbow: without soft start
08:29 AM Longbow: I have a 15kW spindle and need a software soft_start otherwise it rumbles
08:29 AM Longbow: especially when slowing down
08:30 AM gregcnc: why does the spindle drive run it correctly?
08:30 AM gregcnc: doesn't
08:30 AM Longbow: it is an older bosch system which expects a software soft aceleration.
08:31 AM JT-Shop: you said the spindle is off
08:31 AM Longbow: yes for testing but now I will enable it to see if it goes trough the code
08:31 AM Longbow: because it is probably waiting for sindle at speed
08:32 AM JT-Shop: it is waiting for spindle at speed if you have that function in your hal file
08:36 AM Longbow: ok thanks. But if I comment that line M3 10000?
08:37 AM Longbow: it will still wait for the spindle?
08:37 AM gregcnc: is there is no spindle command what would it waiting for?
08:37 AM Longbow: nothing :D
08:38 AM Longbow: it works now! Thank you!
08:38 AM Longbow: I asked because what is the point to run with no spindle. So I tought that it will look for it anyways :D
08:39 AM gregcnc: spindle is only needed if you tell the machine it's needed
08:40 AM Longbow: ok. Now it sucessfully executed the code :) :) :)
08:40 AM Longbow: time for PID tuning the drives :D
08:41 AM gregcnc: vise vs press https://youtu.be/Z255Ns8Sw0g?t=51s
09:37 AM os1r1s: JT-Shop Vise keys are awesome!
11:08 AM JT-Shop: anyone running debian wheezy and has a second to test something
11:29 AM Todd_Z: What do you want to test?
11:39 AM JT-Shop: if PyQt4 is installed by default
11:40 AM JT-Shop: start python in a terminal then say from PyQt4 import QtGui
11:41 AM JT-Shop: well that part came out nice... too bad it's wrong :(
12:08 PM acmehendel: I keep getting a 'would exceed joints 2's positive limit' every time I try to move to a z + direction
12:11 PM JT-Shop: and you should
12:11 PM acmehendel: why?
12:12 PM acmehendel: even after I already moved to a z- position?
12:12 PM JT-Shop: trying to run a file?
12:13 PM acmehendel: yes
12:13 PM acmehendel: one of the sample files
12:14 PM JT-Shop: my guess is you did not touch off Z
12:14 PM _methods: did you home the machine?
12:14 PM JT-Shop: I don't think you can run a file not homed unless you configure that
12:15 PM _methods: yeah well he probably homed it on top of the part
12:15 PM _methods: instead of touching off
12:15 PM _methods: if i had to guess
12:15 PM acmehendel: probablyt
12:15 PM JT-Shop: or he didn't look at the hint in the splash code :)
12:16 PM acmehendel: I did home it but i did not touch it off
12:16 PM _methods: home vs work coordinate offset
12:16 PM acmehendel: rather 'the machine'
12:16 PM acmehendel: Its only a simulator
12:16 PM JT-Shop: you still have to do what it says on line 4
12:20 PM acmehendel: Is there a way to 'reset' back to where the machine is at x0y0z0 if I touch off in the wrong place? or screw something up
12:25 PM acmehendel: ok, i just did the thing on the splash screen
12:25 PM acmehendel: moved down a little on the z axis then touch off
12:26 PM acmehendel: still getting 'would exceed join 2 positive limit' error
12:36 PM _methods: so when you say moved it down a little is more than than positive move in the program?
12:36 PM archivist: acmehendel, there is a box, does the item fit it, no, shift something till it does or reset machine limits
12:36 PM _methods: if its not larger than the positive move you will of course get a limit error
12:43 PM ripple1: wheres the chatlog these days?
12:44 PM ripple1: ohhh
12:44 PM ripple1: right
12:44 PM acmehendel: I think I understand what youre saying _methods after you mentioned it just now I moved the 'spindle' further down in to the box.
12:44 PM ripple1: beautiful
12:44 PM JT-Shop: your welcome
12:44 PM Cromaglious_: morning
12:44 PM ripple1: morning
12:46 PM Cromaglious_: back to trying to figure out nontrivial kinematics in HAL... cartesian to polar
12:46 PM ripple1: JT-Shop: lots of product moving on the website?
12:46 PM Cromaglious_: whois jt-shop
12:46 PM acmehendel: ok, so I moved the z axis more negative. and after touching off I am now able to move it in a 'positive direction. However when I try to home now I get an error stating 'cannot home while shared home switch is closed'
12:47 PM ripple1: your switch is already activated you have to move off of the switch to start the homing sequence
12:47 PM Cromaglious_: you can't have the other axis on a home switch if they are shared
12:48 PM Cromaglious_: which is why you have home switches for X and Y like at -5mm and home at 0, and Z at 5mm and home position is at 0
12:49 PM acmehendel: ok, i think i understand.
12:49 PM Cromaglious_: that way the axis will move off home switch so the other axis can home
12:51 PM JT-Shop: ripple1: it's slowly increasing as I add more products and cards
12:53 PM Cromaglious_: just ordered 3 new hall effect sensors because my mechanical home switches would vibrate and give false readings
12:54 PM ripple1: good I had in communication with a guy for awhile about getting the ball rolling on getting you some industrial cased fanless sbc's but our conversation tapered off round christmas, I was hoping he just took it over with you :)
12:54 PM acmehendel: where do I set things like the G54 coordinates?
12:54 PM ripple1: I was in communication*
12:55 PM Cromaglious_: touch off button
12:56 PM ripple1: acmehendel: I think you need to take out all your tooling and crash course around for a month on it :)
12:57 PM JT-Shop: acmehendel: what are you trying to do? you select the G54 coordinate system...
12:57 PM Cromaglious_: breaking tools is half the learning experience... plus putting holes in your table...
12:58 PM acmehendel: heh. I'm running it as a simulator
01:00 PM Cromaglious_: I got my linuxcnc computer sitting in the living room downloading debian 8.7 amd64
01:01 PM Cromaglious_: I have linuxcnc on this laptop just for simulation and having a HAL file handy
01:15 PM ripple1: My favorite setup is to have a laptop and install gigolo and remmina, then on each cnc machine autostart x11vnc -loop and then I have full control of each setup with drag and drop filesharing
01:16 PM acmehendel: when I use the mdi in some cases I get 'unknown gcode used' how would I add a particular gcode to the '
01:16 PM acmehendel: the 'library' if there is any?
01:16 PM acmehendel: its g code g23
01:16 PM _methods: wtf is g23?
01:17 PM acmehendel: it may not be important, but it seems to be a fanuc specific code
01:17 PM ripple1: *frantically googles g23*
01:17 PM _methods: http://linuxcnc.org/docs/html/gcode.html
01:17 PM acmehendel: 'stored stroke check function off'
01:17 PM _methods: but you're using linuxcnc
01:17 PM ripple1: ^
01:18 PM ripple1: Gcode is not a universal language
01:18 PM acmehendel: i understand, but I want to simulate 'things'
01:18 PM skunkworks_: acmehendel, http://linuxcnc.org/docs/ja/html/remap/remap.html
01:19 PM _methods: http://linuxcnc.org/docs/html/gcode/g-code.html
01:19 PM skunkworks_: looks like g23 is open to remap
01:19 PM acmehendel: i dont even know what stored stroke check function is
01:19 PM acmehendel: off or on
01:20 PM _methods: you're trying to simulate something when you don't even know what it is?
01:21 PM acmehendel: isnt that the process of learning something?
01:21 PM acmehendel: i didnt know to not expect g23 to be in there
01:23 PM _methods: that 2nd link i posted has a list of all the linuxcnc gcodes
01:23 PM _methods: http://linuxcnc.org/docs/html/gcode/g-code.html
01:23 PM _methods: and skunkworks_ posted how to remap gcodes
01:28 PM ripple1: acmehendel: save your ?s for actual issues that you are at your ropes end when you can. Im not saying to not ask questions on a conversational level by any means. Im just saying that people may become hesitant to put their time and effort into solutions if they feel they are in vain. Looking back I have hundreds of cringeworthy questions i've asked :)
01:29 PM acmehendel: i understand
01:36 PM Cromaglious_: ripple1, so true
01:36 PM ripple1: Down my rocky road of linux I found out often that asking for the documentation that has your answer will get you much farther along than asking for a specific answer.
01:42 PM * JT-Shop grins when someone says they like the documents :)
01:43 PM ripple1: I always have trouble seeing the forest through all the trees, I'll read and read and it just wont hit me and then one day it all comes together and I feel like a fool. ahahaha
01:45 PM _methods: i find people have the hardest time grasping work coordinate vs machine coordinates and some people seem to have a hard time grasping tool length offsets for some reason
01:46 PM ripple1: For example I spent a 2 weeks trying different ways of getting linuxcnc to execute bash scripts without using mdi mode. I read the same forum post multiple times and never realized it was answering all my questions until I came in here and anarchist point me right back to the same documentation I had been at... so dumb hahahaha thx again anarchist! :P
01:46 PM _methods: most people seem to grasp cutter radius compensation pretty quickly when you draw them a picture of the cutter around a profile
01:46 PM acmehendel: dont blame yourself too much, linux documentation in general is notorious for being somewhat archaic
01:47 PM ripple1: I still dont understand any of that _methods but im working on understanding joints vs axis compiling new Rt components! how backwards is that?
01:48 PM _methods: not really backwards if that's where your needs lie
01:48 PM ripple1: exactly
01:48 PM ripple1: I used linuxcnc more like a plc with motion and quick changeover
01:48 PM ripple1: not really as a conventional mill or lathe
01:49 PM ripple1: I never used the tool tables or the coordinate modes either. im just now getting into switching between absolute and incremental modes
01:49 PM JT-Shop: you use classicladder?
01:50 PM ripple1: some
01:50 PM JT-Shop: cool
01:50 PM ripple1: but only where i need simulatnious io work done, like conveyors or triggers for and or not stuff
01:53 PM ripple1: i have one machine which is all I/O no classicladder and just does like m66p1l3q2000;m65p4;g4p[1]; etc etc basicly gates, pistons, air driven drilling units on an inline track. so if I need to work on it I just switch programs and say dry cycle the heads to get the air out of the hydraulics. its just so easy and fast to confure
01:53 PM ripple1: configure
01:55 PM ripple1: JT-Shop: best idea you should put on your website
01:55 PM ripple1: a home automation kit
01:56 PM JT-Shop: like an X10?
01:56 PM ripple1: fully loaded for linuxcnc controls via cellphone interface
01:56 PM ripple1: X10?
01:56 PM ripple1: i see
01:56 PM ripple1: similar
01:57 PM ripple1: but I been having this idea for farmers and people who have multiple out structures that need monitored
01:57 PM ripple1: imagine a henhouse, with heaters and lamps and tempuratures
01:57 PM ripple1: they need to control such things and this would be wonderful low cost route
01:59 PM JT-Shop: I can get modules that you can text and tell them what to turn on and off and they text back
02:00 PM ripple1: good, so in reality that an array of those on ladder logic talking to a main linuxcnc interface would be able to control them according to their states
02:02 PM ripple1: I had intentions of putting a wifi unit in a 4 plug outlet strip with relay controlled outlets. then controlling talking to them remotely with linuxcnc
02:04 PM Cromaglious_: that would be kewlios
02:05 PM ripple1: okay this is beautiful I love these things
02:05 PM ripple1: http://www.ebay.com/itm/Western-Reserve-Controls-WRC4-A24H-Circuit-Board-With-Output-Modules-OB5S-IB5S-/172517040567?hash=item282ad121b7:g:lRQAAOSwA3dYb-wl
02:05 PM ripple1: you can plug three of these directly into a mesa 7i80/90 etc
02:06 PM ripple1: bam input OR outputs..... 110v, 220, ac/dc 2v 20v wehatever module you need you just plug it in
02:06 PM Cromaglious_: I have a AmericanDJ relay box, 8 relay switched output 1 always hot. I'm using a arduino mega to switch them on and off
02:07 PM ripple1: imagine putting a mesa card <$100 and snagging three of these fully loaded, you could automate the lighting of a warehouse
02:07 PM ripple1: i mean just as an example
02:08 PM JT-Shop: yea the opto22 boards is a quick way to get 24 I/O on a 50 pin header
02:08 PM Cromaglious_: finally got my sewing machine part brazed... having it clamped in the vice sucked to much heat out... I had a 5/16 bolt with alot of thread and clamped it together with 2 nuts then clamped the bolt head in the vice. I finally got enough heat into it
02:08 PM ripple1: cost is nil, installation is pure profit and just packing it all together and putting it on a website with programmer timers, delays, tempurature controllers, water pumps with feedback for when things get full, you name it
02:09 PM JT-Shop: with a 7i74 you can get 8 x 48 I/O
02:09 PM ripple1: amazing how much difference it makes when you give it less room for it to run
02:10 PM ripple1: ha I know, you could build a massive automation system for someone if you were good with classicladder and gcode sub routines and so forth
02:10 PM JT-Shop: programming done back to the mill for me
02:10 PM ripple1: :) take care
02:15 PM Cromaglious_: X10 was a home automation using the house wiring to transmit information to the receivers. Modern house are to noisy for X10
02:20 PM ripple1: ohh, yeah, i did have an idea to replace each 110 switch with a built in wifi unit (something any handyman can pull off) then it would have 1relay and input which would signal back to a router its current state. From there a person could signal it remotely and know whether it was on or not. Scenario; "farmer john left lights on in barn 2- hes lazy, uses cellphone hits button on phone" Ad wifi extenders to
02:20 PM ripple1: each outbuilding and one linuxcnc unit in where the internet connection comes in from and you have complete control of the grounds without any special wiring.
02:22 PM Cromaglious_: hmm wifi or bluetooth....
02:23 PM Cromaglious_: arduino BT module is a HC608 or something? a AT tiny 85, a relay
02:24 PM ripple1: I was thinking somethign along the lines of, the guts of a IP webcam so you have some bells and whistles to play with
02:24 PM ripple1: but I really dont know how bt works
02:24 PM ripple1: so I suspected wifi by default anyhow
02:28 PM ripple1: One thing nice would be that you could extend the software on the main unit to include ZONEMINDER and a person could monitor each location by simply adding more cameras
02:32 PM Cromaglious_: BT on arduino is pretty easy... BT4 is pretty fast for low res 15fps cameras
03:03 PM [cnc] is now known as [cube]
03:45 PM Cromaglious_: they have the laser tachs and laser thermometers, why can't they have both in one?
03:47 PM XXCoder: trying first flavored soylent bottles lol
03:47 PM XXCoder: hope its good.
03:55 PM Cromaglious_: you know what the green one is made out of... ;)
03:57 PM Cromaglious_: ouch found a laser tach/temp $150
04:00 PM XXCoder: yep soy and lentils
04:03 PM skunkworks: ripple1, those opto22 boards interface directly with mesa hardware
04:03 PM skunkworks: we use them a lot...
04:04 PM skunkworks: http://electronicsam.com/images/matsuura/20170121_153520.jpg
04:05 PM skunkworks: a mesa remote board that runs 2 of those opto22 boards
04:05 PM Cromaglious_: $9 laser thermometer http://www.ebay.com/itm/4-PCS-Nice-Non-Contact-LCD-IR-Laser-Infrared-Digital-Temperature-Thermometer-Gun-/122214805591?var=&hash=item1c7491f057:m:mu6Cj03vQPBbUhQK93TZHxQ
04:05 PM Cromaglious_: just ordered one
04:06 PM XXCoder: 4 peices for dollar?
04:07 PM XXCoder: ah no thats unselected price lol
04:07 PM skunkworks: ripple1, actually that one is a bit odd.. it is 22 realay vs 24... The 24 relay boards for sure interface with mesa
04:08 PM Cromaglious_: and just order this $10 tach http://www.ebay.com/itm/Handheld-LCD-Digital-Laser-Photo-Tachometer-Non-Contact-RPM-Tach-Tester-Meter-/272526814453?hash=item3f73dd2cf5:g:rr0AAOSw-0xYf7v6
04:08 PM Cromaglious_: ordered
04:08 PM XXCoder: yep
04:08 PM XXCoder: order 2 for cheaper than that 150 combo
04:08 PM Deejay: gn8
04:09 PM Cromaglious_: nigt deejay
04:09 PM Deejay: :)
05:12 PM os1r1s: skunkworks Which boards are those?
05:20 PM ripple1: skunkworks: do you do the quotes for what you build? If I ever did retrofits on used machines I wouldnt know how to value the work.
05:21 PM _methods: time and materials
05:21 PM roycroft: i'm in the process of designing the control panel for my cnc milling machine, and i've been reading a book on cnc programming that discusses control panels
05:21 PM ripple1: andypugh: thanks for your work on https://forum.linuxcnc.org/21-axis/29552-reload-program-through-pin?start=20#61763 its absolutely what I needed to execute bash scripts without jumping into mdi mode first
05:21 PM roycroft: it mentions that there is often a "dry run" switch on the panel
05:22 PM roycroft: which runs with faster feeds than normal
05:22 PM roycroft: intended for testing a program without a part or tooling before running it for real
05:22 PM roycroft: is this dry run switch something that folks generally do?
05:22 PM roycroft: is it that much better than doing a simulation within linuxcnc?
05:23 PM andypugh: roycroft: I have heard of it.
05:23 PM roycroft: and can it be easily implemented in linuxcnc?
05:23 PM andypugh: I sometimes do a run without a tool in the spindle to see if things look right.
05:23 PM roycroft: this book likes to talk about fanuc controllers
05:23 PM roycroft: so it may be common on those
05:23 PM ripple1: on linuxcnc axis interface there is a feed overide slider and jog overide slider for this type of adjustment, but yes you can definately add a button which would flip everything into 150% speeds
05:24 PM roycroft: i'm not looking to install as many switches as possible on my control panel
05:24 PM andypugh: ripple1: I had forgotten that I did that.
05:24 PM ripple1: I dont think you know how useful it is!
05:24 PM roycroft: yes, i plan on adding feed and spindle overrides
05:24 PM JT-Shop: it would look too much like your brew stand then
05:24 PM roycroft: my brew stand has exactly enough switches :)
05:24 PM andypugh: I think for a no-tool dry-run you might want rapid speed everywhere, rather than just 150%.
05:24 PM roycroft: which is the optimal amount to have on anything
05:25 PM roycroft: the book also discusses a rapid override, whose utility i feel might not be that great
05:25 PM roycroft: it would be a rapid decrease, not increase
05:25 PM andypugh: ripple1: It should probably have a sleep() function in the loop to make it less of a resource-hog
05:25 PM roycroft: i suppose it might be useful for the overly timid cnc operator
05:26 PM _methods: rapid override is one of the most used switches on a cnc
05:26 PM ripple1: now I can fire off all sorts of automated things I need to have happen which are not related to gcode, like update a webpage with button, print labels, backup files, turn on and off the media players,etc
05:26 PM andypugh: roycroft: The LinuxCNC “Max Velocity” slider limits both feeds and rapids.
05:26 PM ripple1: oh?
05:26 PM _methods: that and feed override
05:26 PM roycroft: it is?
05:26 PM _methods: especially when proving out a new program
05:26 PM _methods: yes
05:26 PM roycroft: ok
05:26 PM * roycroft believes
05:26 PM _methods: it's absolutely indispensable
05:27 PM andypugh: I never use it :-)
05:27 PM _methods: along with spindle and feed override
05:27 PM ripple1: right now im picking an physical switch and firing off a sequence of halcmd's which autohome and automatically upload a new gcode then reload the file and hit play
05:27 PM roycroft: you never prove out new programs - you've done it all
05:28 PM roycroft: i shall add that to my list of things to put on the panel
05:29 PM _methods: its usually not such a big deal when you only have 1 tool or you manually change tools
05:29 PM _methods: but proving out a program with 30 diff tools
05:30 PM _methods: and 20 diff work offsets
05:30 PM _methods: you definitely need it
05:30 PM ripple1: I dont know how you cnc guys keep your head wrapped around all the offsets
05:30 PM _methods: it can get a little crazy on a crowded tombstone
05:31 PM ripple1: im used to production parts so I just run a scrap piece, check it, make a tweak, scrap another, tweak, then run it for days on end
05:32 PM ripple1: I just got this job, .250 diam by 2.5" long radius ends, cycletime 4 seconds
05:32 PM ripple1: hahahaha
05:32 PM ripple1: 5,000 pcs
05:42 PM ripple1: jeesh this godaddy webhosting im using is silly, they give me 10gb space for my website, then they leave a folder in the ROOT directly writable AND I use symbolic links to download from that location. so in essence I get some ridiculous amount of space to host stuff if they dont ever look for it. :P
05:50 PM Tom_L: mmm 57mph wind gusts with wildfires in the area
05:51 PM ripple1: oh noes, where you?
05:52 PM ripple1: *does rain dance*
05:54 PM Tom_L: http://www.kake.com/story/34674010/fire-burns-more-than-5000-acres-in-central-kansas-no-injuries
06:01 PM ripple1: essentially a fire 1 mile away could be in your face in 1 minute and probably quadruple in size given the perfect conditions
06:12 PM os1r1s: Tom_L How would you hook this up to a 7i76?
06:12 PM os1r1s: Tom_L https://www.dropbox.com/s/yt82pzqg0laj6ym/tlocir.jpg?dl=0
06:12 PM os1r1s: I'm guessing the + to common positive and the - to one of the pins pulled down
06:15 PM Tom_L: may need a resistor between
06:15 PM Tom_L: but sounds right
06:18 PM os1r1s: k. thx
06:26 PM insomnia is now known as BipolarBear
08:29 PM MacGalempsy: good evening
08:37 PM ripple1: Gooooooooooood eveeeennenenenenningg sir
08:43 PM MacGalempsy: living the dream?
08:44 PM ripple1: ha, from where i come from we call these nightmares
08:44 PM MacGalempsy: sounds like a good reason to move
08:45 PM ripple1: I was thinking kansas until recently
08:45 PM MacGalempsy: where are you now?
08:45 PM ripple1: indiana
08:45 PM MacGalempsy: ah ok. kansas wouldnt be too different
08:46 PM ripple1: nah, canada seems interesting but there isnt much industry in the places I visited
08:46 PM ripple1: not sure I would be as happy with my work options
08:46 PM MacGalempsy: work to live vs live to work
08:48 PM ripple1: with the route im on now (investing time into complicated machine setups) Im hoping will continue to provide me with work I can do remotely, which would really open up my locations to live in
08:50 PM MacGalempsy: sounds like a good goal
08:52 PM ripple1: the most annoying part is making all the machines I configure something I can easily network to no matter what the company uses for internet connection. I was considering figuring out if it would be a reasonable idea to have some kind of wifihotspot I can mail them which they connect to the machine and it would do some reverse ssh directly back to me
08:56 PM MacGalempsy: you'll figure it out.
09:15 PM * roycroft wonders if president ryan will eliminate medicare by the time he's eligible
09:15 PM roycroft: ack, mischan
09:16 PM ripple1: lel
09:16 PM roycroft: sorry, i'm really trying to keep the politics out of here :)
09:18 PM ripple1: Its amazing how good the self governing is in this room, I never seen any hotbutton topics get too deep
09:18 PM ripple1: probably the worst is argueing over the BEST way to do some THING
09:19 PM roycroft: we're a diverse lot
09:19 PM roycroft: who have something in common
09:20 PM ripple1: irc seems to be pull tug at all the nooks and crannies of the world for clever people
09:25 PM MacGalempsy: the popular mechanics archive is pretty cool
09:26 PM malcom2073: ripple1: Typically a channel like this attracts more intelligent people than say, a channel about cars. Intelligence is linearly ralted to the ability to know when to keep your mouth shut.
09:27 PM ripple1: generally :)
09:27 PM malcom2073: :)
09:27 PM ripple1: for me Im just smart enough to be dangerous so I walk the lines here =D
09:29 PM malcom2073: I'm smart enough to use linuxcnc, but not smart enough to know when to keep my mouth shut :)
09:31 PM ripple1: I need to get a group of people to pick up where im not so good at things on projects. I got a good enclosure guy, a good shop for building machines but i need someone who is really good with linux and likes doing all programming. I can put all the big pieces together but Im a terribly messy programmer :P
09:32 PM malcom2073: +1 to that. I can do mechanical design and programming, but I can't do electronics for the life of me heh
09:32 PM MacGalempsy: study time!
09:33 PM ripple1: Im okay and figuring out everything I need to for industrial controls and electronics and can hook everything up but it doesnt look very nice hahaa I make my brother go back and clean the boxes up tight after I show him how they get wired
09:34 PM malcom2073: Wiring I can do, but circuit design and pcb design I just can't seem to properly wrap my head around
09:34 PM ripple1: ohhh pcb design, nope, never done it
09:37 PM ripple1: I would be much more keen to engineering custom cnc machines than I would packaging up circuits. I could accurately name about 6 components on any given circuit board
09:37 PM MacGalempsy: https://flic.kr/p/RrRjCf
09:37 PM MacGalempsy: Popular Mechanics Apr 1910, a poem to wireless
09:37 PM MacGalempsy: lol
09:38 PM ripple1: this is your "study time" materials? :P
09:39 PM MacGalempsy: yeah. im looking for old ideas to remake
09:39 PM ripple1: oooh
09:41 PM MacGalempsy: like when mountain biking in 1910 the popular brake upgrade was to down a tree and drag it behind you
09:41 PM ripple1: genius
10:42 PM cncnoob: Hey guys. Does anyone use Camworks, and if so what post processor are you using?
10:43 PM cncnoob: I used the only one I could find here: https://forum.linuxcnc.org/31-cad-cam/26124-camworks-post-processor-for-linuxcnc#29542
10:43 PM cncnoob: I wanted to try my luck with another one if one existed to see if it would give me more acceptable gcode
10:45 PM cncnoob: Hey guys. Does anyone use Camworks, and if so what post processor are you using?
10:46 PM cncnoob: I used the only one I could find here: https://forum.linuxcnc.org/31-cad-cam/26124-camworks-post-processor-for-linuxcnc#29542
10:46 PM cncnoob: I wanted to try my luck with another one if one existed to see if it would give me more acceptable gcode
10:47 PM cncnoob: sorry if all that came through twice
10:47 PM cncnoob: I was having connection issues
10:55 PM MacGalempsy: ahhh. roblox is so fun. lol
11:06 PM SpeedEvil: http://www.ebay.co.uk/itm/Trumpf-L2530-laser-4kw-sheet-metal-cutting-machine-/222424944512?hash=item33c98f4f80%3Ag%3AEDUAAOSwB-1Ytbs2 I feel this seller may not fully have understood ebay.
11:06 PM Jymmm: skunkworks: Ya think? "50% Positive Feedback"
11:07 PM SpeedEvil: Also - BIN of 0.99
11:10 PM Jymmm: SpeedEvil: I thik they are just using ebay as a marketing/ad sort of thing, not a "real" auction.
11:11 PM SpeedEvil: yeah - but they don't say that
11:11 PM Jymmm: Heh "BUTY IT NOW"
11:11 PM Wolf_: May not post to United States - Read item description or contact seller for postage options <damn
11:11 PM Jymmm: Wolf_: It's a ebay uk
11:12 PM Wolf_: I know this
11:12 PM roycroft: a trustyworthy ebay seller will have >98% positive feedbackhere is a real scammer:
11:12 PM roycroft: https://www.amazon.com/gp/offer-listing/B000M67TJ2/ref=dp_olp_all_mbc?ie=UTF8&condition=all
11:12 PM Jymmm: Contact 07834 205 699 or sales@zebramachinery.com for price
11:12 PM roycroft: ack, and that first line was supposed to be two lines
11:12 PM roycroft: but check that listing on amazon
11:12 PM roycroft: the $499 one
11:13 PM roycroft: it says "contact me before ordering"
11:13 PM roycroft: you can find a lot of machinery for a fraction of the street price on amazon with that "contact me before ordering" line
11:13 PM roycroft: and they always have you send them money outside of amazon
11:13 PM roycroft: and they always keep it and don't send your stuff
11:14 PM Jymmm: roycroft: seller information "just launched"
11:14 PM roycroft: yes
11:14 PM roycroft: that's also almost always the case
11:15 PM roycroft: i report them when i have the time
11:15 PM roycroft: but i'm not sure it really matters, as they relaunch under a new name as soon as they're cut off
11:17 PM roycroft: i've had a number of ebay sellers trying to pull the same crap
11:17 PM roycroft: they say in the listing "wait for an invoice before paying"
11:17 PM roycroft: and then they try to talk you into paying outside of ebay/paypal
11:18 PM roycroft: i report them and have ebay cancel the sale when that happens
11:19 PM Jymmm: roycroft: How am I suppose to pay the rent if you keep reporting me?!
11:19 PM roycroft: years ago i was looking for a copy of autocad
11:20 PM roycroft: someone was selling a copy of autocad 2008 one ebay for $399
11:20 PM roycroft: i emailed him and asked if it was legit, and if he had all the docs and the ability to transfer the license, etc.
11:20 PM roycroft: he responded that everything was totally legit
11:20 PM roycroft: so i decided to pop for it
11:20 PM roycroft: good price on a slightly older version (this was like 2011)
11:20 PM roycroft: i got a dvd-r in the mail
11:21 PM roycroft: with a crack key
11:21 PM roycroft: i reported it to paypal
11:21 PM roycroft: i reported it to autodesk
11:21 PM roycroft: and i reported to ebay
11:21 PM roycroft: paypal refunded my money immediately
11:21 PM roycroft: ebay sent the seller a nastygram
11:21 PM roycroft: the seller send me a nasty note saying "you knew what you were getting"
11:21 PM roycroft: and he refunded my money
11:22 PM roycroft: so i got refunded twice
11:22 PM roycroft: and i did not feel bad
11:22 PM Wolf_: lol
11:22 PM Jymmm: lol
11:22 PM Jymmm: Now WHOS the scammer here?! huh? huh? huh?
11:22 PM Jymmm: WHO's
11:22 PM roycroft: note that i did not ask the seller for a refund
11:22 PM Jymmm: lol
11:22 PM Wolf_: autodesk
11:22 PM roycroft: i had already been refunded :)
11:23 PM roycroft: about six months later i started getting emails from the seller asking me if i wanted to buy warez from him
11:23 PM roycroft: i found that a bit odd
11:23 PM roycroft: but then i figured i was dealing with a low double digits iq person
11:24 PM Wolf_: should have asked for a list, contact each co on it
11:24 PM roycroft: yeah, i could have forwarded it on to each vendor
11:24 PM Jymmm: roycroft: Nah, it was an 11yo
11:24 PM roycroft: i think they don't generally like to pursue pirates
11:24 PM roycroft: because it's a lot of hassle
11:25 PM roycroft: so his iq matched his age, jymmm
11:25 PM Jymmm: I'm feeling like a pirate right now
11:26 PM Jymmm: Hacking OSS distros to make ISO files
11:26 PM Jymmm: OSX*
11:26 PM Jymmm: Ironically... all perfectly legit.
11:27 PM Jymmm: But taking a long ass damn time!
11:27 PM roycroft: https://www.amazon.com/gp/offer-listing/B000051WSL/ref=dp_olp_all_mbc?ie=UTF8&condition=all
11:28 PM roycroft: note the one for $499
11:28 PM roycroft: does that seller look familiar?
11:28 PM MacGalempsy: if the deal looks too good to be true, 99% of the time it is a scam
11:29 PM roycroft: https://www.amazon.com/sp?_encoding=UTF8&asin=B000051WSL&isAmazonFulfilled=0&isCBA=&marketplaceID=ATVPDKIKX0DER&orderID=&seller=A384GQ3Z044GGD&tab=&vasStoreID=
11:29 PM roycroft: do all those items have something in common?
11:29 PM Jymmm: WTF?! "This copy of the "Install OSX" application is too old to be opened on this version of OSX" bastards
11:29 PM * roycroft thinks it would be pretty easy for amazon to automatically find these folks
11:30 PM ripple1: I wonder how many of them folks are just computer scripts
11:30 PM Jymmm: roycroft: You mean the like "Great Gifts for Mothers Day" and their upselling "Divorce for Dummies"???
11:31 PM MacGalempsy: Hmmm 499 seems to be the price point
11:31 PM roycroft: for a pretzel or a lamborghini
11:31 PM roycroft: it's the $499 store!
11:32 PM MacGalempsy: yup!
