12:09 AM Elmo40: damn... i should become a rigger!
12:14 AM Elmo40: they want $3,500 to load a 125Hp screw drive compressor onto your trailer.
12:14 AM Elmo40: is it going to take 5 days??
12:14 AM Elmo40: like, WTF.
12:14 AM Elmo40: i'd be surprised if it sold at the auction for more than 4,000
12:24 AM CaptHindsight: lots of scammy auctions with high rigging fees
12:24 AM CaptHindsight: must use our rigger, cnc machine $200
12:24 AM flyback: yes seriously sadly
12:24 AM flyback: goodnight
12:24 AM CaptHindsight: some outfit in CA had a bunch of really big older VMC's
12:25 AM CaptHindsight: but they all had high rigging fees
12:30 AM Elmo40: such a shame they have to do that
03:05 AM BitEvil is now known as SpeedEvil
04:20 AM Deejay: moin
04:54 AM jthornton: morning
05:17 AM Tom_L: morning
05:17 AM XXCoder: morning
05:19 AM pink_vampire: morning
07:26 AM jthornton: hmm the ender 3 hot end fan keeps stopping... I
07:26 AM jthornton: 've replaced it
07:26 AM jthornton: so I guess a loose connection or something
07:29 AM pink_vampire: can someone help with a recipe for engraving?
07:29 AM jthornton: 2 parts flour 1 part water and a dash of salt
07:35 AM pink_vampire: I have 0.1mm 10 degrees D bit from ebay, that I can't make ANYTHING with it
07:35 AM pink_vampire: any idea for feeds and speeds?
07:35 AM XXCoder: try wood
07:35 AM XXCoder: see if it works. rpm at whatever high speed
07:35 AM pink_vampire: I want to make a pcb with it
07:35 AM pink_vampire: now I'm working with 1/32" and the pcb look very good
07:39 AM XXCoder: heh thats way faster than my machine limit
07:39 AM XXCoder: but no idea what pcb needs
07:40 AM jthornton: pink_vampire, try a quality bit...
07:41 AM pink_vampire: jthornton: I know.. and I have very good ones made in usa
07:42 AM pink_vampire: but those shi*ty cutter are all over the internet, so I'm curious if I can make anything useful with them?
07:43 AM pink_vampire: the only thing that I did with them that was nice, was text engraving on wood
07:43 AM XXCoder: im sure it works fine with good. awesome engraving wood
07:43 AM XXCoder: *wood
07:50 AM pink_vampire: this is the engraving that I did on wood years ago https://i.imgur.com/uLQeBPz.png
07:50 AM pink_vampire: maybe a bit better https://i.imgur.com/p8YikzK.png
07:53 AM XXCoder: nice
08:13 AM Elmo40: is it a 1-flute?
08:18 AM Elmo40: you know, a blade on half of the tool?
08:18 AM Elmo40: and it doesn't need a pointy botton for engraving PCB. maybe a tiny radius to keep the width but not go too deep.
08:44 AM pink_vampire: Elmo40: yes it is the half tool
08:46 AM pink_vampire: Elmo40: https://images-na.ssl-images-amazon.com/images/I/61-QdVi-UQL._SX425_.jpg
08:46 AM pink_vampire: this crap^
08:46 AM pink_vampire: Elmo40: do you know how to make them cut pcb?
10:25 AM Elmo40: i think it is too pointy
10:25 AM Elmo40: you aren't engraving. you are removing a layer of copper.
10:26 AM Elmo40: those are for engraving things like rings or trophy plaques... they make a fine pointed line
10:26 AM Elmo40: pink_vampire, you should use a tiny endmill to work on pcb
10:27 AM Elmo40: https://www.amazon.ca/Carbide-Endmill-0-2mm-Ideal-Engineering-Electronics/dp/B008RE2VJ4
10:27 AM Elmo40: like these
10:27 AM Elmo40: or wider
10:29 AM pink_vampire: Elmo40: the link you posted is junk, look at the reviews
10:29 AM pink_vampire: 1 star
11:02 AM jymmmm: YAY blackouts and wildfires (over 100 miles away from me)
11:03 AM pink_vampire: O_O
11:04 AM pink_vampire: jymmmm: where are you?
11:09 AM jymmmm: pink_vampire: kommifornia =)
11:14 AM jymmmm: pink_vampire: where are you?
11:14 AM pink_vampire: NY
11:15 AM jymmmm: ah
11:17 AM jymmmm: Making a marking knife... https://www.youtube.com/watch?v=MFGdSAiQGBc
11:18 AM pink_vampire: I'm fine with craft blade
11:35 AM Deejay: re
11:49 AM pink_vampire: Deejay: !!!!
11:49 AM Deejay: hi pink
11:49 AM pink_vampire: long time
11:57 AM jymmmm: Hey Deejay
01:06 PM drdoc: good morning, folks
01:11 PM drdoc: How many of y'all use Pololu-style drivers? Other than current limitations, is there any reason not to use them?
01:17 PM drdoc: jymmmm: I have lust in my heart for that belt grinder
01:20 PM drdoc: my old Grizzly is way too fast for damn near everything
01:24 PM pink_vampire: Pololu-style drivers???
01:25 PM pink_vampire: drdoc: ??
01:49 PM jymmmm: drdoc: Yeah, I noticed that too =)
01:56 PM pink_vampire: maybe you can use something like that https://www.harborfreight.com/router-speed-control-43060.html
02:01 PM taloot: hi
02:01 PM taloot: any idea why lpt pcie card not working in win10 and debian
02:02 PM taloot: i have 3 cards frm d,iffrent suppliers
02:02 PM taloot: all not showing.. in both
02:07 PM taloot: ax99100
02:48 PM FinboySlick: It's from a while back but I just ran into this yesterday: https://www.youtube.com/watch?v=k5zsQ5irMsg
02:48 PM FinboySlick: I think it's pretty cool.
02:48 PM pink_vampire: ooolddd
02:48 PM pink_vampire: but super cool
02:51 PM pink_vampire: FinboySlick: https://www.kickstarter.com/projects/1260359869/swissmak-the-mill-turn-center-for-your-machine-sho
02:56 PM XXCoder: checked chat seems not shupped yet
03:01 PM XXCoder: tariffs hurt them then lot they was on was being sold
03:01 PM XXCoder: bad timing
03:03 PM FinboySlick: pink_vampire: They're moving from Cali to Taiwan to avoid tarifs... So much for american made.
03:06 PM XXCoder: they already made some parts
03:06 PM XXCoder: so its somewhat american made
03:07 PM XXCoder: tons pics https://www.kickstarter.com/projects/1260359869/swissmak-the-mill-turn-center-for-your-machine-sho/posts/2439257
03:09 PM FinboySlick: I'm a bit confused, they put a lot of emphais on odrive but they seem to be using steppers.
03:18 PM Deejay: gn8
03:36 PM andypugh: Hmm, I don’t like the design as much as the (much smaller, and much more expensive) PocketNC. So I suspect it isn’t expensive enough to really exist….
03:38 PM andypugh: They only raised $187,000. I don’t see that as enough to go in to production.
03:43 PM SpeedEvil: It's actually a scam to get someone a really nice 5 axis mill before returning the rest of the money
03:43 PM XXCoder: and waste lot of it on bunch of metal parts
03:46 PM jymmmm: SpeedEvil: I resemble that remark
04:03 PM drdoc: pink_vampire: I have a bunch of A4988 stepper drivers, and a CNC Shield.
04:04 PM drdoc: I'm setting the shield up as a breakout for the A4988s, like this:
04:04 PM drdoc: https://www.v1engineering.com/forum/topic/inexpensive-linuxcnc-interface-for-mpcnc/
04:05 PM drdoc: I won't be able to afford "real" drivers or heavier steppers for awhile
04:08 PM drdoc: So, unless there's a good reason to replace all the drivers ASAP, the plan is to replace my 50oz/in nema 17 motors and A4988 drivers a pair at a time
04:18 PM drdoc: pink_vampire: I was also kind of curious about the smaller/lighter machines the folk here run.
04:19 PM drdoc: Is it customary to run standalone drives, like the Leadshine or Gecko, even with low-torque motors?
04:19 PM pink_vampire: what machine do you have?
04:19 PM jymmmm: pink_vampire: he runs the whole thing on two 9v batteries in parallel =)
04:20 PM jymmmm: ...including the spindle =)
04:20 PM pink_vampire: O_O
04:20 PM drdoc: jymmmm: that's uncomfortably close...
04:20 PM drdoc: https://imgur.com/a/xtgQoat
04:21 PM drdoc: it will eventually be mostly metal and have decent NEMA 23 motors and a real spindle
04:21 PM pink_vampire: I want to make a cnc router
04:22 PM drdoc: literally the only parts there that I didn't have on hand was some of the M5 screws, the lead screws & nuts, and that router bit.
04:22 PM drdoc: well, and the GRBL Shield
04:22 PM drdoc: which I intensely dislike
04:22 PM pink_vampire: how is GRBL vs LINUX CNC?
04:23 PM drdoc: I haven't gotten far enough with LCNC to know
04:23 PM drdoc: but GRBL vs, say, Repetier, is *awful*
04:23 PM drdoc: an 8-bit AVR is just not enough oomph to do the math
04:24 PM jymmmm: GRBL vs gcode you mean?
04:24 PM drdoc: and GRBL seems to have been designed from a 3D printing experience
04:24 PM pink_vampire: can you say what problems do you have with it?
04:24 PM drdoc: jymmmm: GRBl ostensibly runs GCODE
04:24 PM jymmmm: drdoc: PArker OEM 750 is anther driver alternative (lots sold on ebay)
04:25 PM jymmmm: you just have to check often
04:25 PM drdoc: I'm looking at STEPPERONLINE's rebadged DM542T, too
04:25 PM drdoc: $68 shipped for a 3nm motor and the driver
04:25 PM drdoc: Amazon
04:26 PM drdoc: that driver gets very good reviews
04:26 PM drdoc: pink_vampire: my motors SCREAM running under GRBL
04:26 PM jymmmm: https://www.ebay.com/itm/Parker-OEM750-stepping-motor-driver-Lot-4/163796037157
04:26 PM jymmmm: drdoc: https://www.ebay.com/itm/Parker-OEM750-stepping-motor-driver-Lot-4/163796037157
04:26 PM drdoc: I used them for months on a 3D printer running Repetier firmware, and they're not that loud
04:27 PM drdoc: jymmmm: I'm heavily underemployed right now
04:27 PM pink_vampire: drdoc: maybe you need to set the current
04:28 PM drdoc: pink_vampire: have done
04:29 PM drdoc: those are literally the same stepper sdrivers, set to the same reference voltage, driving the same motors as was on my printer
04:29 PM drdoc: and even running with no load they're stupidly loud
04:29 PM jymmmm: drdoc: No worries, just showing you can get a LOT of 4 for $280, and someone else is selling ONE for $1200
04:30 PM drdoc: Oh, I know, and I'd love to be able to do that
04:30 PM drdoc: but the idea, given my resources, is to replace driver/motor pairs a set at a time
04:30 PM pink_vampire: I need to look at the stacklight just to make sure the machine is on
04:31 PM drdoc: pink_vampire: the other thing is that any of the 8-bit Arduino CNC controllers are hard-limited by the speed of the processor
04:32 PM drdoc: Marlin and Repetier use some double/quad-stepping magic to get reasonable speeds, but GRBL does not.
04:32 PM pink_vampire: but 3d printers have much larger gcode files
04:33 PM drdoc: and?
04:33 PM pink_vampire: and the arduino mega run it perfect
04:33 PM drdoc: seriously, if I try to move an axis at over about 450mm/min, it hangs and wails after 20mm
04:34 PM drdoc: pink_vampire: the length of the file isn't relevant
04:34 PM drdoc: both 3D printer firmware and GRBL buffer a few lines at a time
04:36 PM pink_vampire: sounds like the problems that I had with mach3
04:36 PM drdoc: the bottom line is that I've not found one instance of someone trying both linuxCNC and GRBL and deciding to go with GRBL
04:36 PM drdoc: and the forums are loaded with LCNC users who graduated from GRBL
04:37 PM pink_vampire: but you don't need a pc for grbl
04:37 PM drdoc: ok
04:37 PM drdoc: are you running GRBL?
04:38 PM pink_vampire: I love the fact that my 3d printer is standalone
04:38 PM pink_vampire: my cnc mill run linux cnc
04:38 PM drdoc: I mean, there are a ton of people cutting parts with GRBL-driven rigs
04:38 PM drdoc: I just don't like it
04:39 PM drdoc: the post processors are crap
04:39 PM drdoc: it's slow
04:39 PM pink_vampire: what is the rapids on your machine?
04:40 PM drdoc: You still have to have a head - it's not like a 3D printer where you can put the file on an SD card and run it
04:40 PM drdoc: I can run X at about 600mm/min
04:40 PM drdoc: Y at 2/3 that
04:40 PM pink_vampire: my 3d printer can do 120mm/sec
04:41 PM drdoc: See Above: Re: quad-stepping magic
04:41 PM drdoc: what f/w are you using on your printer?
04:41 PM pink_vampire: what is quad-stepping magic?
04:41 PM drdoc: what f/w are you using on your printer?
04:41 PM pink_vampire: no idea
04:41 PM drdoc: what printer?
04:41 PM pink_vampire: it is used printer
04:42 PM pink_vampire: acrylic
04:42 PM drdoc: Anet?
04:42 PM pink_vampire: no, cheaper
04:42 PM drdoc: probably a Marlin variant then
04:44 PM pink_vampire: my printer https://i.imgur.com/sqGs1Hz.png
04:46 PM pink_vampire: the printer have lcd with 4 lines
04:46 PM drdoc: the firmwares that I've worked with calculate longer moves in a way that halves or quarters the number of pulses/second
04:47 PM drdoc: anyway
04:47 PM pink_vampire: you are sounds much more educated then me on that topic
04:48 PM pink_vampire: the cnc panel https://i.imgur.com/JAotJPH.png
04:48 PM drdoc: I designed and built my own printer, so I had to learn
04:48 PM drdoc: sweet
04:49 PM drdoc: you asked why I want to move away from GRBL
04:49 PM drdoc: the short version is that I've run the same hardware with 3D printing firmware, with much better results
04:50 PM pink_vampire: I did't know about that
04:50 PM drdoc: which indicates to me that GRBL isn't very well-done - either badly designed or just not ready for prime time
04:50 PM pink_vampire: so you get poor cut?
04:51 PM drdoc: the controller is the slowest part of my system
04:52 PM drdoc: so unless I slow down to silly speeds, I'm losing steps or straight-up hanging
04:52 PM pink_vampire: what is the theoretical resolution of your machine?
04:52 PM drdoc: have you ever heard of kaizen?
04:52 PM drdoc: 800 steps/mm
04:53 PM pink_vampire: no
04:53 PM drdoc: I have a starting point - the machine you see on Imgur
04:54 PM drdoc: I've identified the major limiting factor - the speed of the Arduino-based controller
04:54 PM pink_vampire: try to lower it to about 100 steps/mm
04:54 PM drdoc: that won't help the post-processing
04:55 PM pink_vampire: can you explain?
04:55 PM drdoc: Even using *very* conservative toolpaths and speeds, I've yet to get a complete run out of the gcode generated by Fusion 360
04:56 PM drdoc: a GRBL post for Mastercam doesn't even exist
04:56 PM pink_vampire: what error / problems you have?
04:56 PM drdoc: mostly rounding errors that lead to out-of-range deviations
04:57 PM drdoc: I know there are solutions to that, but the point is that I can continue to solve the symptoms forever, or I can cure the problem
04:57 PM pink_vampire: can you post here a problematic gcode file
04:58 PM drdoc: no.
04:58 PM roycroft: hey folks
04:58 PM drdoc: hey roycroft
04:58 PM roycroft: i have a 5" 4-jaw chuck that i want to mount on my 6" rotary table
04:58 PM pink_vampire: hi roycroft
04:58 PM roycroft: i was thinking of making a backing plate with little tabs
04:58 PM drdoc: pink_vampire: is there some pressing reason for me to beat that horse?
04:58 PM roycroft: but the tabs would have to be really small - 1/2" deep at most
04:59 PM roycroft: and that would be hard to clamp to
04:59 PM roycroft: so i'm thinking maybe i can just drill four holes through the chuck from the face to the back to mount it
04:59 PM roycroft: is that a crazy idea?
04:59 PM drdoc: yes
04:59 PM roycroft: why?
04:59 PM drdoc: :-)
04:59 PM roycroft: it's a 4-jaw
04:59 PM roycroft: no scroll
04:59 PM pink_vampire: just make bigger plate
05:00 PM roycroft: the rotary table is only 6" in diameter
05:00 PM drdoc: roycroft: I see the problem, but I think I'd make 2 plates
05:00 PM roycroft: a bigger plate wouldn't do me much good, i don't think
05:00 PM drdoc: Not so much to preserve the chuck but to add versatility
05:00 PM roycroft: and this chuck is just laying around
05:01 PM roycroft: i don't know that i'll ever use it for anything else
05:01 PM pink_vampire: so you have 4 t slots in the rotatory table?
05:01 PM roycroft: yes
05:01 PM roycroft: my thought was to drill four countersunk holes through the chuck, and attach to some t-nuts with socket head screws
05:01 PM drdoc: a 7", for example, base plate with countersunk holes to mount on the table and either studs or tapped holes to mount the chuck
05:01 PM roycroft: so the screw heads would be recessed
05:02 PM drdoc: is the chuck threaded for a lathe spindle?
05:02 PM roycroft: no
05:02 PM roycroft: it has a back plate already
05:02 PM pink_vampire: what do you have on the back of the chuck?
05:02 PM roycroft: it was for my old mini-lathe
05:03 PM roycroft: the backing plate has four small studs that mount to the mini-lathe spindle
05:03 PM drdoc: so make an adapter plate to fit the chuck's backing plate
05:03 PM pink_vampire: I think you can screw them out
05:03 PM roycroft: but i have to mount the backing plate to the chuck before i can mount the backing plate to the rotary table
05:03 PM drdoc: or, you know
05:03 PM roycroft: which leaves me with the same problem
05:03 PM drdoc: drill some holes in the chuck
05:03 PM roycroft: only 1/2" outside the chuck in each side to mount the backing plate to the rotary table
05:04 PM pink_vampire: roycroft: you over think it.
05:04 PM roycroft: what would be the problem with drilling through the face of the chuck?
05:04 PM drdoc: none
05:04 PM roycroft: i'm trying to think of one and i can't
05:04 PM roycroft: also, i don't need to register the chuck to the rotary table
05:04 PM roycroft: because it's a 4-jaw
05:04 PM drdoc: right
05:05 PM roycroft: i just need to index the center of the rotary table
05:05 PM roycroft: mount the chuck
05:05 PM roycroft: then index my part
05:05 PM pink_vampire: and 1/2 steel X 4 can take a lot of load
05:05 PM drdoc: what I was thinking is that an adapter plate could give you capacity to mount, say, a bigger mill vise too
05:05 PM drdoc: you'd have to replace the chuck's backing plate
05:05 PM pink_vampire: you can also make long T nuts, with off center thread
05:06 PM roycroft: so here's the other part of this
05:06 PM andypugh: Is the chuck smaller than the rotary?
05:06 PM roycroft: yes
05:06 PM roycroft: 5" chuck
05:06 PM roycroft: 6" rotary table
05:06 PM roycroft: it's smaller, but doesn't leave me a lot of room
05:06 PM roycroft: my other problem is that i don't have a good way to face a backing plate that large on my lathe
05:06 PM drdoc: ah
05:06 PM andypugh: The common solution then, would be a 6” backing plate, with bolt holes at the edge
05:06 PM pink_vampire: 1/2" is fine for a bolt
05:07 PM roycroft: the back of the chuck is already flat
05:07 PM drdoc: that is a showstopper
05:07 PM roycroft: andypugh: they would have to be really small bolt holes
05:07 PM roycroft: drdoc: i could come up with a way to do it
05:07 PM pink_vampire: or you can make 2 plates with a neck
05:07 PM andypugh: 1/2” heads?
05:08 PM roycroft: but don't have a chuck big enough to hold a 6" disk on the lathe
05:08 PM drdoc: roycroft: I tend to go buy machine-plate drops for stuff like that
05:08 PM roycroft: i could bore a hole through the plate, and turn it between centers
05:08 PM roycroft: but that would be a lot of work
05:08 PM roycroft: drilling through the face of the chuck seems the easy way to get it done
05:08 PM drdoc: but in the short term, I'd probably do what you're doing
05:08 PM andypugh: M6 would fit easily. M8 at a pinch. You are unlikely to break 4 x M6 bolts.
05:08 PM roycroft: well i'm not doing it yet
05:09 PM roycroft: i'm hearing a lot of "i would not do that"
05:09 PM drdoc: you know what I mean
05:09 PM roycroft: but i'm not hearing any reasons not to
05:09 PM andypugh: You can face the plate on the mill. Using the rotary table.
05:09 PM roycroft: that i could
05:09 PM drdoc: my only reason not to is "I'll probably want to mount something else sooner or later"
05:10 PM roycroft: but how would my proposed method prevent me from mounting something else later?
05:10 PM drdoc: it won't
05:10 PM roycroft: i would not be doing anything at all to the rotary table
05:10 PM drdoc: I just hate solving the same problem twice
05:10 PM roycroft: and i would be drilling four holes in the chuck that i can't see affecting it negatively in any way
05:11 PM drdoc: I do think Andy has a point though
05:11 PM roycroft: and any solution involving a backing plate would require me to get a backing plate of some sort
05:11 PM roycroft: my proposed solution would cost four bolts and an hour
05:11 PM roycroft: i did look for backing plate blanks, btw
05:12 PM drdoc: an M6 socket head is, what, a 10mm head?
05:12 PM andypugh: Yes.
05:12 PM andypugh: M8 is 13mm head
05:12 PM roycroft: and i did not find any suitable ones, but i could get a 6" threaded one with a spud sticking out the back and mill the stud down
05:12 PM drdoc: I might try just drilling the existing backing plate
05:12 PM roycroft: the existing backing plate is 5"
05:13 PM drdoc: oh
05:13 PM roycroft: so that would not help
05:13 PM drdoc: I misunderstood - I thought you were considering a tabbed backing plate
05:13 PM roycroft: i am
05:13 PM roycroft: but it would have to be 6" - the size of the rotary table
05:13 PM drdoc: right
05:14 PM roycroft: the one i have is 5" - the size of the chuck
05:14 PM andypugh: You might as well drill through the chuck though. Especially if it is never going on a lathe again.
05:14 PM drdoc: ~12mm wide tab is enough for an M6 screw
05:14 PM roycroft: it's not
05:14 PM drdoc: then drill it
05:14 PM drdoc: done.
05:14 PM roycroft: but even if it were, i don't see how drilling it as i propose would affect it, other than having four holes to collect swarf
05:15 PM roycroft: i sense a general reluctance to drill through a chuck
05:15 PM drdoc: well, there's balance, but one assumes you'd do it right
05:15 PM roycroft: and i kind of feel that myself
05:15 PM drdoc: I think you just nailed it
05:15 PM roycroft: it seems to me that the sensible thing is to use the existing mounting plate holes
05:15 PM roycroft: yeah
05:15 PM drdoc: it's a knee-jerk "Noooooooo"
05:15 PM roycroft: but that's just a feeling
05:15 PM roycroft: and i'm looking for an objective reason :)
05:15 PM roycroft: this is a cheap chinese chuck
05:15 PM drdoc: objectivity is overrated
05:16 PM drdoc: and chinese 4-jaws are, what, $35?
05:16 PM roycroft: which probably alleviates much of the queesiness factor
05:16 PM roycroft: about $80
05:16 PM drdoc: yeah - your time is worth more than the hardware
05:16 PM roycroft: probably $140 in this age of tariffs
05:17 PM roycroft: that the chinese are NOT paying
05:17 PM drdoc: I'm not taking that bait
05:17 PM drdoc: :-p
05:17 PM roycroft: it's not bait
05:17 PM roycroft: it's truth
05:17 PM drdoc: I realize you speak truth
05:18 PM roycroft: go to a major import site like grizzly.com
05:18 PM drdoc: it's just not a soapbox I should climb up on today
05:18 PM roycroft: and your jaw will drop when you see how much prices have gone up
05:18 PM drdoc: it's just not a soapbox I should climb up on today
05:18 PM drdoc: it's just not a soapbox I should climb up on today
05:18 PM drdoc: :-)
05:18 PM roycroft: it's ok
05:18 PM roycroft: i'm done :)
05:18 PM drdoc: I'm not capable of sensible discourse
05:18 PM roycroft: i think i deserve a wee rant about it once in a while
05:18 PM drdoc: oh yeah
05:18 PM drdoc: I didn't mean you shouldn't
05:18 PM roycroft: so anyway, other than a general feeling that it's not good to drill on chucks, what i propose is probably fine
05:19 PM drdoc: yes
05:19 PM drdoc: it's meant to mount flat, instead of on a centered thread, so you know it's flat
05:19 PM drdoc: -ish, at least
05:19 PM roycroft: it's as flat as the chinese factory made it
05:19 PM andypugh: If it makes you feel better, I later drilled through this 12” Burnerd chuck. Because it was no use to me as a lathe chuck. https://photos.app.goo.gl/tgNqSezkyYpXEXCx5
05:19 PM drdoc: and it's a 4-jaw
05:20 PM roycroft: and a backing plate is not going to make it any flatter :)
05:20 PM drdoc: if you unbalance it a bit, you probably weren't ever going to turn it that fast anyway
05:20 PM roycroft: i would not unbalance it
05:20 PM roycroft: because i would be drilling 4 holes, 90 degrees apart
05:20 PM drdoc: I believe it
05:21 PM drdoc: just saying
05:21 PM roycroft: the jaws themselves unbalance it more than the holes i would bore
05:21 PM drdoc: it's designed for off-center parts to begin with
05:21 PM roycroft: but it's never going to turn faster than i can crank the rotary table anyway
05:22 PM roycroft: if i were to mount a 3-jaw on the rotary table it would be a completely different story, of course
05:22 PM andypugh: You can’t see, but it is bolted down with through-bolts here: https://photos.app.goo.gl/LggwNXeshSpBrynS9
05:22 PM drdoc: andypugh: I'm having a brain fart on the make & model, but my last job scrapped a 24 x 96 Korean-War-era lathe last year
05:22 PM roycroft: and i'd probably get a 4" 3-jaw so i had plenty of room fdor the mounting plate
05:23 PM drdoc: it had an oddball 19.5" chuck
05:24 PM drdoc: total wiehgt without any tooling was almost exactly what my grandma's old '72 Lincoln 4-door weighed
05:25 PM andypugh: I keep thinking about making a mill-table-mounted D1-4 for all my other chucks. I have a bit of a chick collecting problem. 4-jaw, 3 x normal 3-jaw (one with reversejaws mounted) 1 x bolted-on soft-jaw, 1 x magnetic, 1 x Burnerd Multisize, 1 x 5C collet…
05:25 PM _unreal_: hello
05:25 PM roycroft: i don't have enough chucks
05:26 PM drdoc: heh
05:26 PM _unreal_: chucks?
05:26 PM drdoc: you need a jeweler's lathe
05:26 PM andypugh: Err, chuck collecting problem. I appear to be utterly useless at collecting “chicks”. There may be a correlation.
05:26 PM roycroft: if you ever feel burdened by an excess of them, i'd be happy to send you an airbill number so that you can post any extras to me :)
05:26 PM drdoc: ooooh
05:27 PM _unreal_: hum
05:27 PM roycroft: i wish i had reverse jaws for the 6" 3 jaw on my lathe
05:27 PM _unreal_: I need to show you guys some photos of some hardware I have when i geta round to taking some pics and posting photos
05:27 PM _unreal_: trying to figure out what to do with the hardware
05:27 PM roycroft: if i did i'd easily be able to mount larger parts like that backing plate on the lathe
05:27 PM andypugh: 3D print some jaws
05:27 PM _unreal_: just got home need to take a shower
05:27 PM drdoc: if any of y'all happen to have a spare set of stepped pulleys for a double-stepdown drill, I'd love to know
05:27 PM _unreal_: andypugh, there ya go
05:28 PM drdoc: my drill press has the mounts for the middle pulley
05:28 PM roycroft: i've seen chucks with reversable jaws
05:28 PM _unreal_: drdoc, those dont cost much
05:28 PM roycroft: that would be kind of neat
05:28 PM roycroft: and i mean scroll chucks
05:28 PM roycroft: the gripping part of the jaws are bolted to the moving part
05:28 PM roycroft: so you can unbolt them and flip them around
05:29 PM roycroft: i should imagine that they're even less accurate than regular scroll chucks though
05:29 PM andypugh: I am not actually joking about 3D printing jaws, here are some that I 3D printed for a special job: https://photos.app.goo.gl/LggwNXeshSpBrynS9
05:30 PM _unreal_: drdoc, do you have an A axis on your cnc?
05:30 PM roycroft: i did not think you were joking
05:30 PM roycroft: but i don't have a 3d printer
05:30 PM drdoc: _unreal_: I know, but "not much" and "dirt cheap" is a fairly important distinction these days
05:30 PM andypugh: Well, that’s easily fixed. SImply apply money.
05:30 PM andypugh: (My 3D printer was < £200 )
05:31 PM roycroft: that link points to your previous link
05:31 PM drdoc: _unreal_: that depends
05:31 PM drdoc: :-)
05:31 PM andypugh: https://photos.app.goo.gl/PZBWNB9ouJEhx3ed8
05:31 PM drdoc: I have 2 motors driving the gantry
05:31 PM roycroft: yeah, but not just money for the printer
05:31 PM roycroft: i'd need money for the extension to my shop so i would have room for the printer
05:32 PM drdoc: I much prefer to do Y + A over doubling them
05:32 PM _unreal_: roycroft, I was looking REALLY hard for the 3d printed chcuks in that last link
05:32 PM _unreal_: lol
05:32 PM andypugh: Keep it in kitchen cupboard, loads of spare space there :-)
05:32 PM roycroft: i'm not "one of those people" who puts machinery in my living room :P
05:32 PM * drdoc looks at the CNC router in the dining room
05:32 PM _unreal_: ? andypugh is that mill in your living room?
05:32 PM roycroft: my cupboards are burtsting with food, dishes, cookware, etc.
05:33 PM roycroft: bursting, rather
05:33 PM drdoc: OK
05:33 PM _unreal_: I have my desktop mill in my room
05:33 PM roycroft: anway
05:33 PM andypugh: What kind of wierdo would have a mill in their living room?
05:33 PM drdoc: I'm going to ask again, since I didn't get any feedback before
05:33 PM roycroft: i'm thinking that it's time to figure out a bolt pattern for the chuck now
05:33 PM _unreal_: then again I'm a full time single father. who is a house sitter for my father becuase he has 3 homes
05:33 PM pink_vampire: andypugh: how did you make those buttons?
05:34 PM andypugh: Apart from anything else, there isn’t room for a mill in my living room. Err, because of the lathe.
05:34 PM drdoc: given that I'm running 1.5A stepper motors, is there any downside to using Pololu drivers as opposed to stnadalone drivers?
05:34 PM andypugh: pink_vampire: Which buttons? On the mill?
05:34 PM roycroft: sorry to have interrupted your previous conversation, drdoc
05:34 PM drdoc: you didn't\
05:34 PM roycroft: usually folks carry out mulitple conversations here simultaneously
05:34 PM pink_vampire: the play pause stop...
05:35 PM drdoc: nobody really addressed the question earlier
05:35 PM roycroft: but when i mentioned drilling a chuck everyone jumped in
05:35 PM drdoc: so I'm asking again
05:35 PM _unreal_: drdoc, pololu drives are stand alone. they are just banked on an arduino often
05:35 PM roycroft: i guess the queesiness factor is really high when it comes to that :)
05:35 PM drdoc: lol!
05:35 PM drdoc: _unreal_: point
05:35 PM roycroft: but i think i'm gonna do it
05:36 PM roycroft: i just need to measure the t-slots on the rotary table so i know what size bolts to drill for
05:36 PM drdoc: roycroft: I get that, but a $75 driver pushing a 60oz/in motor seems... excessive
05:36 PM _unreal_: and drdoc you beat me then. My highest rated motor on my home cnc is 1.4A
05:36 PM _unreal_: 1.4 1.2 1.0 amps
05:36 PM drdoc: my printer motors are 1.72A
05:36 PM roycroft: with the cost of ductile iron i might spend almost as much for a small slab to make a backing plate as the chuck used to cost
05:36 PM _unreal_: ?
05:37 PM _unreal_: drdoc, I assume it moves FAST
05:37 PM _unreal_: what voltage
05:37 PM drdoc: it do
05:37 PM drdoc: 24V
05:37 PM _unreal_: only 24... hum
05:37 PM _unreal_: then again 3d printer. NO load
05:37 PM drdoc: they're overkill for 3D printing, and just *try* to get other electronics rated for >24V
05:38 PM drdoc: my cnc is 24V for now too
05:38 PM _unreal_: hum
05:38 PM _unreal_: same here
05:38 PM _unreal_: my big cnc I'm building I'm using 26v
05:38 PM _unreal_: 36
05:38 PM drdoc: I'm considering chaining another PSU on for 36V
05:38 PM drdoc: :-)
05:38 PM _unreal_: I have dual power supplys setup
05:38 PM _unreal_: so I can divide the 4 motors
05:39 PM _unreal_: as I recall there draw is like 3 amps
05:39 PM _unreal_: so thats upto 6amps per motor
05:39 PM andypugh: pink_vampire: https://www.ebay.com/itm/10x-Arcade-Square-Shape-LED-Illuminated-Push-Buttons-Switch-DC-12V-Jamma-Mame/223492805343 (though possibly bigger) then I printed the logos on to overhead projector transparency at the local photocopy / print shop and put them inside.
05:39 PM _unreal_: and I have I believe 12A psu's
05:39 PM drdoc: my PSU is 62A
05:39 PM _unreal_: 62A GOOD lord
05:40 PM drdoc: waaay overkill for this machine, but it's what I had on hand
05:40 PM _unreal_: ya I was going to say
05:40 PM _unreal_: sooooo how many cnc things are running off that one PSU again :)
05:40 PM drdoc: 2 Dell server PSUs in series
05:40 PM pink_vampire: andypugh: cool!
05:40 PM _unreal_: hum
05:40 PM _unreal_: ? in series
05:40 PM _unreal_: are they SWTICHING psu's?
05:40 PM pink_vampire: but how did you set them up in linux cnc?
05:41 PM drdoc: http://www.tjinguytech.com/my-projects/server-ps
05:42 PM drdoc: server psu are a little different from ATX
05:42 PM _unreal_: ya I was going to say they must be designed to do series
05:42 PM drdoc: they're made to be run in parallel, but I've got several hundred hours on a setup like the 24V setup on that page
05:42 PM _unreal_: hum
05:43 PM _unreal_: as long as the swtiching mosfets can take the voltage hay :)
05:43 PM drdoc: haven't blown one yet...
05:43 PM drdoc: :-)
05:44 PM drdoc: seriously, the current is unbelievably consistent, even with shifting draw
05:44 PM _unreal_: drdoc, I wouldnt draw more then 25% power in that setup though
05:44 PM _unreal_: unless its DESIGNED to be serialed
05:45 PM drdoc: the RC car guys and the crypto miners run them at 80%
05:45 PM _unreal_: ok
05:45 PM _unreal_: then they must be ok
05:45 PM drdoc: crypto mining, for hundreds of hours straight
05:45 PM _unreal_: I know nothing
05:45 PM drdoc: yeah, I did a *lot* of research before setting that up
05:45 PM _unreal_: have you done crypto mining?
05:45 PM drdoc: no
05:45 PM _unreal_: ok
05:46 PM _unreal_: I hear its a fading fad
05:47 PM _unreal_: 1bit coin 7k
05:47 PM drdoc: for any viable currency, the block chains have hit the far side of the diminishing-return curve
05:47 PM drdoc: I expect that cryptocurrency is here to stay
05:47 PM _unreal_: ya
05:47 PM _unreal_: dude you have no idea
05:47 PM drdoc: mining it, maybe not
05:47 PM drdoc: I do
05:48 PM _unreal_: I was || this close to buying
05:48 PM _unreal_: 10k for $100 about????? 7 years ago
05:48 PM drdoc: I know a guy who made a quarter-mil last year day-trading new issues
05:49 PM drdoc: there are 10-50 new crypto currencies a week
05:49 PM jthornton: hmm my hot end fan is not stopping after I added some wires to the terminals so I could read the voltage... I think one was a bit loose
05:49 PM _unreal_: if I had made that purchage and traded them in in 2016 I'd have something like 200 million $
05:49 PM drdoc: most of them top out in a month and die
05:50 PM drdoc: hey, is anybody running their printers with LCNC?
05:50 PM _unreal_: errr NO not for $100 for $1000
05:50 PM drdoc: _unreal_: it looks like nobody cares about pololu drivers
05:50 PM drdoc: :-)
05:50 PM _unreal_: I used that $1000 for a lawyer do to my @#R@#$@#R Xwife out of the blue deciding we were no longer happy and wanted a divorce
05:50 PM drdoc: btdt
05:51 PM _unreal_: btdt?
05:51 PM drdoc: been there, did that
05:51 PM _unreal_: I got the kid though :)
05:51 PM drdoc: there ya go
05:51 PM drdoc: hey, how are you driving those 1.4A motors?
05:51 PM _unreal_: hobbycnc pro
05:52 PM * drdoc googles
05:52 PM _unreal_: $100
05:52 PM _unreal_: AND you have to build it
05:52 PM _unreal_: drdoc, hobbycnc is for unipolar though
05:53 PM _unreal_: do you have unipolar or bipolar
05:53 PM drdoc: bipolar
05:53 PM _unreal_: then it wont help you
05:53 PM andypugh: Pololus work fine on my printer. Try them and see.
05:54 PM _unreal_: I dont know if they have a bipolar vesrion
05:54 PM _unreal_: andypugh, do they get HOT for you?
05:54 PM drdoc: andypugh: they work fine on my printer too
05:54 PM drdoc: I was asking avbout using them on a cnc router
05:54 PM andypugh: No idea, they are out of sight and out of mind
05:54 PM _unreal_: I'm going to use them for my daughters minicnc
05:54 PM _unreal_: drdoc, they should work just fine
05:54 PM _unreal_: as I recall they get HOT easy
05:54 PM _unreal_: and need good cooling
05:55 PM drdoc: _unreal_: buy some RAM heatsinks, or make them
05:55 PM _unreal_: the one's I have came withstick on heat sinks
05:55 PM drdoc: the ones that come with pololu boards aren't enough
05:55 PM _unreal_: my daughters motors are only drawing .5 amps anyways
05:55 PM drdoc: I cut up an old Pentium II heatsink
05:55 PM _unreal_: ! you bastard
05:56 PM drdoc: keep air moving on them
05:56 PM drdoc: ?
05:56 PM _unreal_: what did that bunny suite processor heat sink ever do to you
05:56 PM drdoc: it looked at me funny
05:56 PM _unreal_: I miss those old intel P2 adds
05:56 PM drdoc: OK
05:57 PM _unreal_: remember the colorful hasvab suites for intel?
05:57 PM drdoc: yup
05:57 PM drdoc: I'm considering whipping up a BoB that mounts Pololu drivers directly
05:57 PM _unreal_: https://www.youtube.com/watch?v=paU16B-bZEA
05:57 PM drdoc: you interested?
05:57 PM _unreal_: they even had dalls
05:58 PM drdoc: If a milled PCB works I'll probably have some made up at oshpark
05:58 PM _unreal_: am i interested in what?
05:58 PM drdoc: I'm considering whipping up a BoB that mounts Pololu drivers directly
05:59 PM _unreal_: oh
05:59 PM _unreal_: bob?
05:59 PM drdoc: parallel port breakout
05:59 PM _unreal_: oh breakout board
05:59 PM drdoc: with sockets for DRV8825
05:59 PM _unreal_: you could but....
05:59 PM drdoc: I'm kind of dumbfounded that it's not already a thing
05:59 PM _unreal_: how much did you pay for your pololu drivers?
06:00 PM drdoc: basically nothing
06:00 PM drdoc: about what I'll pay for the breakout board
06:00 PM _unreal_: https://www.amazon.com/gp/product/B06XHKSVTG/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
06:01 PM drdoc: the shield is all you need there, unless you're going to run GRBL
06:01 PM _unreal_: ya
06:01 PM _unreal_: those shields are dirt cheap
06:01 PM _unreal_: thats a full kit
06:01 PM drdoc: plus, the 3.0 boards *still* need a daughterboard for the limit switches
06:02 PM _unreal_: I got that kit as a lighting deal
06:02 PM _unreal_: for it for $12
06:02 PM drdoc: a cheap parallel port breakout is $8
06:02 PM drdoc: a shield another $6-9
06:03 PM drdoc: and I can't be the only one who'll pay a bit more for a less messy setup
06:03 PM _unreal_: I dont think this one needs a daughter boarde for the limit switches
06:03 PM _unreal_: heh
06:03 PM _unreal_: ya I typically just design pcb's in kicad
06:03 PM _unreal_: print transfer etch
06:04 PM drdoc: if it's v3.0, you're likely to get a lot of false hits from EMI
06:04 PM _unreal_: I use a laminator to do the transfers
06:04 PM _unreal_: shrug
06:04 PM _unreal_: I dont know how to tell
06:04 PM drdoc: simple - it'll hit home halfway to the stop
06:05 PM drdoc: I still have a student license for Eagle
06:05 PM drdoc: and one of the big reasons for building the router is to be able to mill PCBs instead of etching
06:06 PM _unreal_: I use to have a full blow hacked version of eagle that had no virii in it
06:06 PM _unreal_: long since forgotten what I did with it
06:06 PM _unreal_: milling is ok but I've not had great luck
06:06 PM drdoc: I'm not terribly happy with the way Autodesk has done Eagle
06:07 PM _unreal_: I've found that I cant even close to the detail i can do with print, transfer and etch
06:07 PM _unreal_: not only that
06:07 PM drdoc: what printer do you use for the trtansfers?
06:07 PM _unreal_: laser and blue transfer
06:08 PM _unreal_: this shit https://www.ebay.com/i/192483838455?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=192483838455&targetid=503482144044&device=c&mktype=pla&googleloc=9012012&poi=&campaignid=6469750213&mkgroupid=77932556779&rlsatarget=aud-762207186714:pla-503482144044&abcId=1141186&merchantid=6296724&gclid=Cj0KCQjwl8XtBRDAARIsAKfwtxCdq6DWgNko_-gDjXhjzxxWr9SqPbg6na00gDnAFHqKcTK521xdtn8aAkE9EALw_wcB
06:08 PM _unreal_: its heat transfer
06:08 PM drdoc: I always used photo paper
06:09 PM _unreal_: so you print directly onto the BLUE stuff with the laser printer. then use an iron. or a laminator like I do
06:09 PM _unreal_: I run it a few times
06:09 PM jthornton: everything after the ? can be dropped from ebay links
06:09 PM _unreal_: ?
06:09 PM jthornton: https://www.ebay.com/i/192483838455
06:09 PM _unreal_: drdoc, so you print on the blue, then you do the heat transfer
06:09 PM jthornton: that should be the same link
06:10 PM _unreal_: and you MUST cool the board before pulling the blue away
06:10 PM _unreal_: I just run it under cold water
06:10 PM drdoc: I might try that
06:10 PM _unreal_: dry and pull slowly
06:10 PM drdoc: you use ferric chloride or acid?
06:10 PM _unreal_: they dont always work
06:10 PM _unreal_: yes
06:10 PM _unreal_: fich
06:10 PM _unreal_: ferric
06:10 PM drdoc: ok
06:10 PM _unreal_: aldo
06:10 PM _unreal_: arg
06:11 PM _unreal_: also
06:11 PM _unreal_: I use ziplock bags
06:11 PM drdoc: I've had good luck using cheap laser photo paper
06:11 PM drdoc: but you don't get much detail
06:11 PM _unreal_: so for small bags I use little snack pack ziplock bags. a little FC, and then put the pcb in. and then put that BAG into a bigger higher quality bag
06:11 PM drdoc: I'd never heard of the blue transfer stuff
06:12 PM _unreal_: give me a sec and I'll show you some of my work
06:13 PM _unreal_: drdoc, :)
06:13 PM _unreal_: https://drive.google.com/open?id=1IsCViJMKJoHJ_kMOssT3BuV9c7jD8j3Z
06:13 PM roycroft: well, minor pause, due to the aesthetic queesiness factor
06:13 PM roycroft: the logical plan would be to drill my through holes offset 45 degrees from the jaw axes
06:13 PM roycroft: so that it would look symmetrical
06:14 PM _unreal_: ?
06:14 PM roycroft: but, of course, the existing backing plate mounting holes are in that same location
06:14 PM _unreal_: drdoc, there are a few dual traces between though holes
06:14 PM roycroft: so i either get to drill those through, and not be able to mount the backing plate again, or drill at 22.5 degrees to the jaw axes, which would look really weird
06:15 PM _unreal_: drdoc, ?
06:15 PM drdoc: sorry, was away for a minute
06:15 PM _unreal_: you bastard
06:15 PM drdoc: yeah, I can't get that fine with my printer
06:16 PM drdoc: an old LJ 4100
06:16 PM _unreal_: I with your printer or with your method?
06:16 PM _unreal_: do you have a laser printer
06:16 PM drdoc: the photo paper probably doesn't help

06:18 PM drdoc: Function > Form
06:18 PM _unreal_: drdoc, thats an issue with your toner transfer NOT your laser printer
06:18 PM drdoc: _unreal_: yup
06:18 PM _unreal_: my laser printer looks very much like yours
06:18 PM _unreal_: just older
06:19 PM drdoc: yup
06:20 PM drdoc: but for now I need to get away from the screen
06:23 PM _unreal_: wtf
06:23 PM _unreal_: BIG ass netsplit or something?
06:24 PM _unreal_: drdoc, ?
06:30 PM _unreal_: wtf
06:30 PM _unreal_: anyone live?
06:31 PM _unreal_: hello?
06:31 PM SpeedEvil: ?
06:31 PM _unreal_: I got disconnected and it wouldnt let me reconnect for the past 5min
06:31 PM SpeedEvil: Depends how you define life.
06:31 PM drdoc: _unreal_: I got chores to do
06:32 PM _unreal_: was there like a netsplit or something?
06:34 PM drdoc: doesn't look like it
06:35 PM _unreal_: ya I dont know
06:35 PM _unreal_: so regardless
06:35 PM _unreal_: the blue transfer
06:35 PM _unreal_: its on a plastic film
06:35 PM _unreal_: you have to put paper between your HEAT source and that film
06:35 PM _unreal_: and the inkjet printed side to your PCB
06:35 PM _unreal_: when you peel. the blue rips away from the plastic "overhead" and all of your toner is on the PCB
06:35 PM _unreal_: very clean very sharp
07:25 PM dammitcoetzee: hello! does anyone have any experience using linuxcncrsh? specifically the SET OPEN <file> command? I can't get it to work at all
07:33 PM Tom_L: dammitcoetzee, no experience with that one, sry
07:35 PM Tom_L: are you specifying the path on the linuxcnc pc relative to the working directory?
07:35 PM Tom_L: ( i would start with a simple one )
07:36 PM dammitcoetzee: i tried relative, absolute, quotes, brackets, dots, tildes, haha
07:36 PM Tom_L: :)
07:37 PM dammitcoetzee: just get SET OPEN NAK or OPEN NAK regardless
07:37 PM dammitcoetzee: also tried most of the modes I can think of, enable, estopped, etc.
07:37 PM Tom_L: case sensitive?
07:37 PM dammitcoetzee: no luck
07:37 PM dammitcoetzee: i tried that
07:37 PM Tom_L: man, i've never used the utility
07:37 PM dammitcoetzee: also when i use GET PROGRAM, it sends a regular looking path back
07:38 PM dammitcoetzee: well, i'm writing a python interface for it
07:38 PM Tom_L: nice
07:38 PM Tom_L: might be interesting to see a qtpyvcp one for it
07:40 PM flyback: THEY ARE COMING TOMARROW
07:40 PM flyback: woot
07:40 PM flyback: and I got 20 hard drives imaged
07:40 PM flyback: 10 are not readablebut I will fix them when I complete imaging all the good ones
07:40 PM flyback: the floppy parts come tomarrow
07:40 PM flyback: to make the flux engines
07:41 PM * flyback dropkicks Tom_L

07:42 PM flyback: ddrescue --direct --verbose --force /dev/sdb WDC-WD170AA-WD-WM9680032669.img WDC-WD170AA-WD-WM9680032669.log ; md5sum -b WDC-WD170AA-WD-WM9680032669.img > WDC-WD170AA-WD-WM9680032669.img.md5
07:42 PM flyback: doing them all twice
07:42 PM flyback: 2 different boxes
07:42 PM flyback: then do a bit compare to ensure I got a good read
07:42 PM flyback: I won't be able to do this on ones with bad sectors because one sector might read more than on the other box
07:42 PM flyback: but i'll of something
07:43 PM flyback: two new cp2401's come tomarrow
07:43 PM flyback: I might get another one to salvage to fix a $40 cp2104 breakout board
11:11 PM _unreal_: wow
11:11 PM _unreal_: I have like 200 disconnects
11:11 PM _unreal_: wtf
