12:28 AM miss0r: goodmorning
02:08 AM Deejay: moin
02:40 AM pink_vampire: how do i edit the scale in linux cnc without change the acceleration
02:41 AM pink_vampire: i got the c axis to work, and i think the LPT is too slow for it.
02:44 AM pink_vampire: so i reduce the encoder to half or the resulution, and now the C axis work nice and fast, BUT linux cnc think the 180 deg is full rotation, if i put the correct value in the "SCALE" on the ini, it fix the 180 deg problem, but it is go slow as before
02:45 AM pink_vampire: any idea how to make it spin faster?
04:49 AM jthornton: morning
04:57 AM rmu: physics nobel prize - arthur ashkin, gerard mourou & donna strickland
05:13 AM XXCoder: hey all
05:13 AM pink_vampire: hi
05:13 AM jthornton: damn I found a nice 6" jointer but it' in Springdale Ar and that's a 550 mile round trip
05:14 AM XXCoder: work was pretty nasty. not jobs which was fine
05:14 AM XXCoder: but shop was at two 70s lol
05:14 AM XXCoder: 70f 70% humidity
05:14 AM XXCoder: jthornton: ow gas makes it not worth it so fast even if your time is free
05:14 AM jthornton: 68°F 100% humidity
05:15 AM XXCoder: outside was over 100% for few hours lol its called rain :)
05:15 AM pink_vampire: i can't go faster in the stepgen settings
05:15 AM jthornton: it's the time for me it takes me 10 hours to make that trip
05:15 AM jthornton: just did that the other day to pick up the wood lathe
05:15 AM pink_vampire: I think i got to the limit of LPT
05:16 AM XXCoder: pink lol reminds me one time I played with my own "encoder", it went way over hz limit of sensor itself, I bought a 1khz one but havent tyried it because I moved short time later
05:17 AM pink_vampire: i did some test with tapping in to wood
05:18 AM pink_vampire: but i use g1 Z C code
05:18 AM pink_vampire: so..
05:18 AM pink_vampire: i can't use like g33 commands
05:18 AM XXCoder: is there "clicks per rotation" setting?
05:18 AM jthornton: I think I got my new chicken door code sorted out now I need to ramp the opening time up and down by date what fun
05:18 AM XXCoder: not sure how your encoder work
05:19 AM pink_vampire: i have 1024PPR encoder.
05:20 AM XXCoder: drat I dont know enough about your issue to help sorry :)
05:21 AM pink_vampire: i need to setup my C axis as spindle
05:22 AM XXCoder: none of machines at work that has c axis freely rotate while milling must lock in place
05:22 AM XXCoder: granted only 2 machines has c axis
05:23 AM pink_vampire: can you do ridgid tap on your machines at work?
05:23 AM XXCoder: all of em
05:23 AM XXCoder: its large shop machines after all, the smallest one we have, which is office mill by haas, is $50,000 bucks
05:23 AM pink_vampire: and can you set ans angle?
05:24 AM XXCoder: ans angle?
05:24 AM pink_vampire: i mean to rotate the spindle 90 deg
05:24 AM XXCoder: only one machine at work has spindle that can change angle
05:25 AM XXCoder: its very rare haas machine
05:25 AM XXCoder: its old but I guess haas only made a few and its now essentally nonexistant
05:29 AM XXCoder: how did you halve the resolution anyway
05:33 AM Tom_L: 67°F Hi 87
05:34 AM XXCoder: outside 55f 97% humidity
05:34 AM XXCoder: it was 70f 70% inside shop lol
05:34 AM pink_vampire: XXCoder: there is a dip switch in the encoder, so you can select the resolution you want.
05:35 AM pink_vampire: https://www.cui.com/product/resource/amt10.pdf jump to page 4
05:35 AM XXCoder: walking too fast made me sweaty by humidity
05:35 AM XXCoder: interesting, how do you change resolution of encoder on linuxcnc side?
05:46 AM pink_vampire: in the scale setting under your [AXIS] in the ini file
05:48 AM pink_vampire: XXCoder: ^
05:49 AM XXCoder: so it was also adjusted to reflect your current resolution on encoder?
05:50 AM pink_vampire: yeah, but the acceleration setting also need to be set
05:51 AM XXCoder: thoyght that was not linked to encoder? (not familiar with HAL)
05:54 AM pink_vampire: the encoder connect to the G320X not to linux cnc
05:55 AM XXCoder: g320x has any resolution settings stuff?
05:55 AM pink_vampire: no
05:56 AM pink_vampire: it is the dip switches in the encoder
05:56 AM XXCoder: reading g320x docs
05:57 AM XXCoder: look at step: connecting the encoder https://www.geckodrive.com/support/dc-servo-drives/g320x-rev-10.html
05:59 AM XXCoder: hmm thats for selecting dip switches I guess
06:01 AM pink_vampire: you mean the pulse multiplier in the g320X?
06:01 AM pink_vampire: you can ignore that
06:04 AM XXCoder: guess its for finding optimial resolution, nevermind :)
06:06 AM pink_vampire: i need some FPGA or some better technology that is in use in 2018
06:18 AM fragalot: Hey
06:18 AM XXCoder: hey
06:20 AM jthornton: hay
06:20 AM XXCoder: yay
06:25 AM rmu: pink_vampire: have you looked at setting stepspace to 0 and using hal_parport reset function? that could double you max step frequency
06:50 AM pink_vampire: rmu: I'm not even sure what do you mean
06:52 AM jthornton: pink http://linuxcnc.org/docs/2.7/html/hal/parallel-port.html#_using_doublestep
07:00 AM pink_vampire: I need to read it, and now i'm on my way out, and the machine is off.
07:23 AM miss0r: New cnc controller almost done! :D https://imgur.com/a/JwNRdxp
07:24 AM miss0r: I just need two jumper latches, a usb A-male to A-male plug & to screw all the d-subs in place
07:24 AM pink_vampire: amazing as F*ck!
07:25 AM pink_vampire: sooo nicely done
07:25 AM miss0r: Thanks. But what would've made it look realy good; would've been a larger cabinet, so I didn't have to cram it in there so disorganized
07:26 AM pink_vampire: this is why I'm the gun cabinet
07:26 AM miss0r: gun cabinet?
07:26 AM pink_vampire: it is large and cheap
07:26 AM pink_vampire: yeah
07:27 AM miss0r: I guess; where you are from anyway. 'round here guncabinets are realy expensive
07:27 AM pink_vampire: miss0r: https://i.imgur.com/vUmUIK7.png
07:27 AM pink_vampire: NY
07:27 AM Deejay: big bertha!
07:27 AM Deejay: hrhr
07:27 AM miss0r: damn! sweet
07:27 AM miss0r: Can I offer a word of advice, if you don't mind?
07:27 AM pink_vampire: yeah
07:28 AM miss0r: Those wire ducts you are using, with the slits in the side: They also come in a 5 or 6mm configuration. Those spacings you have make it hard to make realy pretty wiring ;)
07:29 AM pink_vampire: all the din rails are mount on 80/20 rails so it is very easy to change stuff
07:30 AM pink_vampire: I need better wire, I'm using 14AWG
07:30 AM miss0r: I've uploaded a few pictures of some former projects of mine, where 6mm spacing is used: https://imgur.com/a/sjrZhUT
07:30 AM pink_vampire: I think it is the same one
07:31 AM pink_vampire: yours is just much deeper
07:31 AM miss0r: that is one thing; but the spacing in your cable ducts are alot bigger
07:31 AM pink_vampire: https://i.imgur.com/HM2QCGu.png
07:31 AM miss0r: I know the type you've used. I only ever use those for cables, not single wires
07:32 AM miss0r: You can see your terminals; they are most likely ~5mm wide
07:32 AM pink_vampire: the terminals are 6mm each
07:32 AM miss0r: With the smaller spacing, you can 'almost' have the wires running directly from the cable duct to the terminals in a right angle
07:33 AM pink_vampire: where did you got them in the us?
07:33 AM miss0r: I love your terminal markers :)
07:33 AM miss0r: I didn't. I source my stuff locally (Denmark)
07:33 AM miss0r: I can get you an EAN number, if you want?
07:33 AM pink_vampire: I had to special order all the stuff.
07:34 AM miss0r: What are the rough dimensions on those wire ducts you use? WxH ?
07:34 AM pink_vampire: let me see
07:35 AM pink_vampire: 1x3 and 2x3
07:36 AM miss0r: so 25x75 & 50x75 ish
07:36 AM miss0r: (I'm metric :))
07:36 AM pink_vampire: yeah
07:36 AM pink_vampire: I'm also metric, but use also imperial
07:37 AM miss0r: EAN: 4031026567556 This is for a 25x80 from HELLERMANN TYTON
07:38 AM miss0r: EAN: 4031026567563 This is for a 40x80 from HELLERMANN TYTON
07:38 AM pink_vampire: can't find them in the website
07:38 AM pink_vampire: https://www.hellermanntyton.us/search/?keyword=4031026567563
07:39 AM miss0r: try 184-10208
07:39 AM miss0r: and 184-10068 respectively
07:39 AM pink_vampire: 184-10208: 0 Results
07:40 AM miss0r: ... hang on
07:41 AM miss0r: I have it on the danish version :S https://www.hellermanntyton.com/dk/produkter/kabelforing-og-tilbehor/htwd-pn-25x40/184-10068
07:42 AM miss0r: ahh
07:42 AM miss0r: You can't find my metric versions on the US site.
07:42 AM miss0r: https://www.hellermanntyton.us/routing-protection-and-insulation/wiring-duct/high-density-slotted-duct-and-covers/
07:44 AM pink_vampire: even if you get me them free I'm not going to take the whole wires out wayyy too much work.
07:44 AM miss0r: yeah. :) Just for future consideration.
07:45 AM pink_vampire: let me take up to date picture
07:45 AM miss0r: What you have made is looking realy nice. This would just have been adding the icing ;)
07:46 AM pink_vampire: I think the best thing i did was to add light. in the cabinet, much nicer to work
07:47 AM miss0r: hehe yeah :) You'd be surprised how few ever think of that :) Its a realy nice touch
07:52 AM pink_vampire: miss0r: this is with the C axis https://i.imgur.com/xdq1W6s.png
07:53 AM miss0r: That is realy pretty :D
07:54 AM miss0r: Symmetry i everything. And you nailed it :]
07:55 AM pink_vampire: the high voltage is connect together in the wire duct, this is why you see 4 wires come from the same slot in the duct
07:57 AM pink_vampire: miss0r: also huge tip if you need to close a ziptie on wires in the duct, and you don't have the tool that pull them, just use a small long socket as a pipe, and twist the ziptie from the other side. it will save your fingers.
07:57 AM miss0r: so you have wire connections hidden in the duct? ^.-
07:58 AM miss0r: meh. I need to get a move on. I'll be back tonight. See you around
07:59 AM pink_vampire: the low voltage is deeper in the duct
07:59 AM pink_vampire: thanks. see you
08:33 AM beachbumpete1: Morning LinuxCNC :)
08:53 AM Deejay: re
09:01 AM FinboySlick: Yo Pete.
09:01 AM FinboySlick: You have a working lathe now, right? I don't need to pity you anymore.
09:05 AM beachbumpete1: hey finnboy
09:05 AM beachbumpete1: LOL sorry unfortunately I do not
09:05 AM beachbumpete1: Its still a hunk of metal and a bunch of boxes of parts in my garage/shop./
09:07 AM beachbumpete1: FinboySlick: do you have a working lathe now?
09:07 AM FinboySlick: beachbumpete1: It's a sherline, but yes ;)
09:07 AM gregcnc: you latheless types
09:07 AM beachbumpete1: Nice...
09:08 AM beachbumpete1: I really miss my 12x36 manual lathe
09:08 AM beachbumpete1: If I dont get the CNC lathe done in the next few months I may just buy a cheap used manual lathe just to have.
09:10 AM FinboySlick: beachbumpete1: You're in Abom territory. If we tell him some bum in his neighbourhood is neglecting a perfectly viable lathe project, he'll show up at your door with a 3" wrench and motivate you.
09:10 AM beachbumpete1: Hell someone's got to ;)
09:14 AM beachbumpete1: I did not know I was in Abom territory
12:25 PM fragalot: miss0r: any suggestions on how to give a schaublin 13 an enema? (I think my oil disagrees with the previous owners' choice of oil.. it looks iffy and the spindle bogs down if I exceed 1850rpm which I *REALLY* want to resolve before anything gets wrecked)
12:25 PM miss0r: fragalot: Diesel
12:25 PM Loetmichel: yeah, or lamp oil
12:26 PM fragalot: alright
12:26 PM Loetmichel: works well for diluting old grease/oil and get it out
12:26 PM miss0r: use ALOT !
12:26 PM Loetmichel: while still providing SOME lubrication
12:26 PM miss0r: and compressed air. rinse and repeat
12:26 PM miss0r: Then rinse and repeat with the oil you want to use for a few times
12:27 PM fragalot: Aye, I plan to keep rinsing until it comes out the same color as I put in
12:27 PM miss0r: indeed
12:27 PM miss0r: as for the spindle. I would take that apart
12:27 PM miss0r: :)
12:27 PM fragalot: just wanted to know which product would a) work b) not make it worse
12:28 PM miss0r: Indeed
12:28 PM Loetmichel: fragalot: diesel, petroleum, any "light oil" that still has some lubrication effects
12:28 PM fragalot: yeah I want to disassemble the vertical head anyway as I noticed some metal flakes as I flushed oil through there.. Not sure if they're just chips or if it came from inside as it wasn't "clean" :(
12:29 PM miss0r: yeah
12:29 PM fragalot: and the horizontal spindle could probably do with re-packing with fresh grease >.>
12:30 PM miss0r: fragalot: You wouldn't by any chance be interrested in a pentograph? :D
12:31 PM fragalot: I'm being thrown around the head with pantographs
12:31 PM miss0r: hehe
12:31 PM Loetmichel: if i still had that old military truck we used as an RV i would say: "send me the waste, we need fuel"
12:31 PM fragalot: friend of mine has 6, of which he wants to foist 1 off onto me too :D
12:31 PM miss0r: I just stumbled acros a mint condition Deckel one - the same model syyl has
12:31 PM miss0r: and a S0 deckel tool grinder. :D
12:32 PM fragalot: speaking of tool grinders
12:32 PM miss0r: But; A) I don't need it. B) Noone needs it C) I couldn't fit it in here if I tried :D
12:32 PM Loetmichel: ... one time we had the german customs stop us in it... "do you mind if we test your fuel tank for heating oil? (tax reduced diesel)"
12:32 PM fragalot: I figured out why that center drill snapped
12:32 PM fragalot: the damn thing's flutes were ground about 2mm uneven
12:32 PM miss0r: :o
12:32 PM miss0r: user error? :D
12:32 PM Loetmichel: ... driver said "nope, do as you whish"...
12:33 PM fragalot: miss0r: well.. both sides were completely unsymmetrical
12:33 PM fragalot: the tip was centered, but the flutes weren't
12:33 PM miss0r: fragalot: User error? :D
12:33 PM Loetmichel: ... the police officer put his tester into the tank, pulled it out and there was a black, lumply ooze dripping off it...
12:33 PM miss0r: what about the backrake on the end of the flutes?
12:33 PM Loetmichel: "WTF?"
12:34 PM fragalot: miss0r: barely there, but enough for it to cut
12:34 PM miss0r: fragalot: I'm more interrested in if they had the same backrake angle
12:34 PM fragalot: in any case it's now in the scrap bin after I tried to resharpen it to make an 'NC' style spot drill out of the snapped end
12:34 PM Loetmichel: driver: "look at the papers: this car has an "any fuel" engine".... there is about 80 liters used motor oil in it, 60 liters vegetable oil, 30 liters hydraulic oil (used) and a bit of petrol to get that mix to pass the injectors"... ;)
12:34 PM fragalot: miss0r: both ends did, but the 2 flutes on either end didn't
12:35 PM miss0r: odd stuff
12:35 PM miss0r: I know where to get a Deckel S0 tool grinder. Interrested? :P
12:35 PM Loetmichel: ... "but not a single drop of heating oil" ;)
12:35 PM miss0r: Loetmichel: Lol
12:35 PM fragalot: Loetmichel: so you got fined for evading taxes?
12:35 PM Loetmichel: nope
12:36 PM fragalot: miss0r: happy with the current chinesium clone grinder :-)
12:36 PM Loetmichel: if there would be heating oil in it we would have been ;)
12:36 PM miss0r: fragalot: Good for making off-center drills for the odd spotting job :P
12:36 PM Loetmichel: funny thing is that that (diesel) engine even runs with pure ethanol
12:37 PM miss0r: Loetmichel: What kind of an engine is that?
12:37 PM Loetmichel: it dosent care what it runs on as long as its flammable and thin enough to pass the injectors ;)
12:37 PM fragalot: Loetmichel: diesels run on anything flammable
12:37 PM fragalot: :D
12:37 PM Loetmichel: fragalot: yes
12:37 PM Loetmichel: but this engine is MADE to run on anything
12:38 PM Loetmichel: 1:35 or so compression, a injetor pump thats lubed by the main oil circuit and direct injection
12:38 PM * fragalot thinks he needs to find a source to buy oil in QTY's greater than 1l
12:39 PM * miss0r needs to go clean the kitchen :D
12:39 PM miss0r: See you later
12:39 PM fragalot: cya
12:39 PM Loetmichel: miss0r: that: https://www.youtube.com/watch?v=5_wEXtlqqBg
12:40 PM fragalot: almost sounds like a hit'n'miss :P
12:41 PM Loetmichel: https://www.youtube.com/watch?v=IKwoqBK4AXg <- thats the truck
12:41 PM Loetmichel: just that ours looked a lot nicer...
12:42 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16316
12:42 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16320
12:43 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16322
12:43 PM Loetmichel: :-)
12:44 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16318 <- that blonde long haired guy is me... some 2+ decades ago... reparing the servo steering on a street in maroc/atlas mountains ;)
12:49 PM fragalot: this oil alternatives overview table from schaublin makes absolutely no sense
12:49 PM syyl_: oil tables never make sense
12:50 PM fragalot: the central lube and spindle requires either a ISO 10 VG equivalent, or an ISO 32 VG equivalent
12:50 PM fragalot: depending on which one I look up
12:50 PM fragalot: or a 15
12:50 PM syyl_: or any oil as it seems
12:50 PM syyl_: ;)
12:50 PM fragalot: apparently, lol
12:51 PM syyl_: iso 10 is a classic spindle oil
12:51 PM syyl_: but
12:51 PM syyl_: for central lubrication way to fluid
12:51 PM fragalot: well the same oil is used for the ways, central lube, and spindle gear bath
12:51 PM syyl_: hmm
12:51 PM fragalot: and feed gearbox
12:52 PM fragalot: hang on, took pictures of the tables
12:52 PM fragalot: (and you'll be pleased to hear they are in german :P)
12:53 PM fragalot: or something that's supposed to pass as german anyway
12:53 PM fragalot: https://photos.app.goo.gl/tiJmRWuG9STdQA6F9
12:54 PM Loetmichel: fragalot: hihi, what did you expect from a schaublin?
12:54 PM fragalot: Loetmichel: either all french, or all german
12:54 PM fragalot: but this manual is a mix of french, german, or english, depending on the page you're on :D
12:55 PM Loetmichel: nope
12:55 PM Loetmichel: its all three on each page
12:55 PM fragalot: on that page, yes
12:55 PM Loetmichel: its called "multilanguage manual"
12:55 PM syyl_: that oil chart is a mess ;)
12:55 PM syyl_: i correct.
12:56 PM syyl_: oil dessignations are a mess
12:56 PM fragalot: Loetmichel: the oil pages are, probably becaues it's universal for their machines.. but most other sections are in one language only
12:56 PM fragalot: drawings are exclusively swiss french
12:56 PM syyl_: but yes
12:56 PM syyl_: a 32 hydraulic oil should be the right thing
12:56 PM fragalot: thanks syyl_ :)
12:57 PM Loetmichel: fragalot: he is the best to ask such things
12:57 PM Loetmichel: he owns a few of those old clunkers ;)
12:57 PM Loetmichel: <. has no room for such a big machine
12:57 PM syyl_: shell tellus 32 should be the modern version
12:58 PM fragalot: Loetmichel: I don't have the room for this machine either
12:58 PM fragalot: somehow that didn't stop me
12:59 PM syyl_: hey look
12:59 PM syyl_: a shell chart :D
12:59 PM syyl_: https://www.alexoil.co.uk/content/7-shell-pre-iso-iso-lubron-oil-reference-guide
12:59 PM Loetmichel: fragalot: my workshop is the childs room of this flat here... i doubt the floor load would be good for a 2 ton machine ;)
12:59 PM syyl_: tellus 37 is the modern thing
12:59 PM syyl_: its an annoying mess.
12:59 PM fragalot: syyl_: I loev how tellus 11 is actually tellus 5
12:59 PM fragalot: :D
12:59 PM syyl_: yeah
12:59 PM syyl_: :D
01:00 PM syyl_: but as usual, disclaimer
01:00 PM syyl_: if the machine catches fire, its not my fault.
01:01 PM Loetmichel: syyl_: too late. you answered. of course its your fault now. until eternity ;)
01:01 PM fragalot: that'd be the flushing it with diesel part causing the fire
01:01 PM syyl_: *puff*
01:01 PM Loetmichel: fragalot: diesel is surprisingly "unflammable" without a wick
01:02 PM fragalot: :D
01:02 PM fragalot: Loetmichel: or atomisation - I know :)
01:02 PM Loetmichel: indeed
01:02 PM fragalot: you can easily dip a burning torch in a bucket of the stuff
01:02 PM Loetmichel: yes
01:02 PM fragalot: until it's reached the flash point
01:02 PM fragalot: :D
01:02 PM Loetmichel: or harden a orange hot steel part in it
01:03 PM Tom_L: Loetmichel was it you that posted the thread mill video?
01:03 PM Loetmichel: few small flames from the vaporized diesl, then its off
01:03 PM Loetmichel: Tom_L: on the 6040?
01:03 PM Loetmichel: yes
01:03 PM Tom_L: what sort of feeds / speeds did you use?
01:04 PM Loetmichel: look at the end of the video, there is a look on the LinuxCNC window with full program visible... i think at second 52
01:04 PM Tom_L: can you repost it again?
01:05 PM Tom_L: also, what material was that
01:07 PM Loetmichel: alu
01:07 PM Loetmichel: https://www.youtube.com/watch?v=yDcCyF_gVoY
01:07 PM Loetmichel: and a 60° engraving D-bit
01:09 PM Tom_L: not the same one i was thinking of
01:09 PM Loetmichel: sorry then , thats the only one i ever had ;)
01:09 PM syyl_: wasnt that gregcnc?
01:10 PM Tom_L: yeah it could have been greg
01:10 PM gregcnc: uh oh what did i do
01:10 PM syyl_: threadmilling video?
01:11 PM Tom_L: i was interested in the feed/speed you used
01:11 PM gregcnc: phew not me, .0005 to .001ipt
01:11 PM jdh: Loetmichel: got any chinese vfd's talking modbus to linuxcnc?
01:11 PM Tom_L: yeah that's about what i figured
01:11 PM Loetmichel: jdh: yes
01:11 PM jdh: any pointers?
01:12 PM Loetmichel: but cant figure out what i did 5 years ago to reproduce it on the second machine
01:12 PM gregcnc: and compensate feed rate for small radius!
01:12 PM jdh: mine does nothing but could be vfd params, bad 485 convertor, or bad code or bad halcmds
01:13 PM Loetmichel: the electric part is easy, USB-> RS485 converter, is seen as a /ttyx in linux, then 2 wires to the VFD ports, done
01:13 PM Loetmichel: but i dont know any more what i did with the software to connect it
01:13 PM Loetmichel: ast MarkusBec, i think he had it running, too
01:14 PM jdh: I have a usb 232 to a 485 converter that at least shows up in linux. ALso have a usb 485 device with ftdi chip but it doesn't get detected as a serial device
01:24 PM Tom_L: i think andy has hy_vfd running on his
01:31 PM fragalot: miss0r: have you seen 'norsemen' ? :D
01:52 PM gloops: thats why Ichs was so important here, he was well up on the chinese tackle
02:09 PM CaptHindsight: besides the obvious text editors, what's out there for editing G-code? open or closed
02:10 PM CaptHindsight: CAMotics, G-Wizrd, HSM
02:19 PM CaptHindsight: https://buildbotics.com/ a RPi is inside but what the controller software used?
02:28 PM CaptHindsight: yet another project that claims that PC's with parallel ports are hard to find
02:29 PM -!- #linuxcnc mode set to +v by ChanServ
02:29 PM cradek: even if you disregard all the existing computers in the world other than new ones on amazon, it's still not at all hard is it?
02:30 PM CaptHindsight: LPT cards are ~$10 PCI or PCIe
02:32 PM CaptHindsight: that reminds me I have to add that fix for the http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH
02:37 PM Tom_L: CaptHindsight once in a while i use the smartcam editor that came with it
02:37 PM Tom_L: mostly PN or NP++
02:38 PM Tom_L: the native editor lets you do things like math on vars etc
02:38 PM Tom_L: translate ABS->INC
02:38 PM Tom_L: etc
02:40 PM Tom_L: now that my post is fixed i don't have to use one much
02:43 PM CaptHindsight: I have some rather unique CAM
02:44 PM CaptHindsight: maybe extend Blender to do what I need
02:44 PM CaptHindsight: looking at options
02:46 PM CaptHindsight: https://postimg.cc/67Csv2QJ one nozzle already gets complicated since you can modulate ink flow and spot size
02:49 PM pcw_mesa: looks like the buildbotics thing is a RPI + AVR (Arduino?)
02:50 PM CaptHindsight: I skimmed through the firmware at the github
02:53 PM pcw_mesa: a RPI + LinuxCNC +A couple 4 PowerStep01s would likely be better in most ways (80V 10A vs 36V 6A smarter drivers, real display etc etc)
02:56 PM CaptHindsight: they might have gone their direction to be compatible with those other 3-4 automation projects
02:59 PM CaptHindsight: http://openpnp.org/ https://github.com/LaserWeb/LaserWeb4
02:59 PM CaptHindsight: https://github.com/foosel/OctoPrint
03:02 PM CaptHindsight: all these projects are missing features that you end up having to develop vs having it all and not using everything
03:02 PM CaptHindsight: all to avoid using a PC as the controller
03:06 PM CaptHindsight: https://github.com/LaserWeb/LaserWeb4/wiki This Application is built for Chrome Browser only! :)
03:06 PM CaptHindsight: thanks
04:00 PM Deejay: gn8
07:34 PM ziper: how expensive were tools in the old days
07:35 PM ziper: would a drill bit or a file be worth a farmers monthly wage
07:36 PM SpeedEvil: That depends how far back you go.
07:36 PM _unreal_: sup
07:36 PM SpeedEvil: Consider that an hour of farmers time probably would not pay for an hour of smiths time
07:36 PM ziper: say, 1000 AD
07:37 PM Tom_L: did they have iron then?
07:37 PM SpeedEvil: yes.
07:39 PM SpeedEvil: https://thehistoryofengland.co.uk/resource/medieval-prices-and-wages/ may be informative
07:40 PM _unreal_: ziper, So what is your current issue with the fiber glass stuff?
07:40 PM _unreal_: I have 5min
07:40 PM ziper: _unreal_, none really
07:40 PM _unreal_: then my daughter should be done with her homework finally
07:40 PM ziper: just thinking about a wing mast
07:40 PM _unreal_: then you figured out the foam issue?
07:43 PM ziper: expanded polystyrene i guess
07:44 PM _unreal_: would be a good choice
07:44 PM ziper: anyone else reading that link penny is abbreviated as d.
07:44 PM _unreal_: ?
07:45 PM _unreal_: ziper, you should see the projects I've been working on as of late
07:45 PM _unreal_: just finished building a $3k hatch. building an other larger one for an other boat currently
07:48 PM ziper: _unreal_, a deck hatch? how big?
07:48 PM _unreal_: combing hatch....
07:48 PM ziper: SpeedEvil, i guess the crux of the question is how much labor goes into making a file or a drill bit 1000 years ago
07:49 PM _unreal_: and yes one was a deck hatch
07:49 PM SpeedEvil: 'a drill bit'
07:49 PM ziper: gimme dat ltv
07:49 PM _unreal_: ziper, https://drive.google.com/open?id=1-VTq25sgQ9gyRi0d9PAoCxLWfWw2gojt
07:49 PM ziper: a thing that can make a round hole with rotary motion
07:50 PM _unreal_: ziper, splash model https://drive.google.com/open?id=1ZrtAmQHtsQbzgS7A-QYOspxadI0E97Rc
07:50 PM SpeedEvil: you can bang a spade bit out with a hammer and forge and chisel in a couple of minutes if you have a rod.
07:50 PM _unreal_: https://drive.google.com/open?id=1pEzzbuVjsJyeopZItOrOnajISlTwH3NH
07:50 PM _unreal_: mine is on the left https://drive.google.com/open?id=1NzpUX80lrGEdww5ojHptkJF03795CltO
07:51 PM ziper: and for metalworking bits?
07:51 PM SpeedEvil: ziper: Forging would probably be more common I'd expect than drilling.
07:52 PM SpeedEvil: Look at how stuff of the era was made - large blocks of metal weren't common - it was expensive.
07:52 PM ziper: good point. Same think with files?
07:52 PM SpeedEvil: https://www.youtube.com/watch?v=SOw9WqMOHjA&t=1s is excellent
07:52 PM ziper: too valuable to turn into dust
07:52 PM SpeedEvil: goes through the whole process
07:52 PM _unreal_: ziper, did you look at the links?
07:52 PM ziper: _unreal_, yes
07:54 PM ziper: _unreal_, did you make just the lids, or the receptacle too
07:54 PM _unreal_: just the hatch cover....
07:54 PM _unreal_: it broke away in the hurricane last year
07:54 PM ziper: ahh
08:09 PM ziper: thanks speedevil that video was just what i was looking for
08:13 PM SpeedEvil: Lots in the same series.
08:13 PM SpeedEvil: Making drillbits and ...
08:15 PM SpeedEvil: however - note that very little work of that type was being done - wheelbarrows have not been found mentioned before 1100s for example.
08:15 PM SpeedEvil: https://en.wikipedia.org/wiki/Medieval_technology
