12:22 AM Crom_: ugh... Delivery guy hid my new Dell Wyse thin clients behind the trailer...
12:25 AM Crom_: grrr they didn't come with wifi...
12:32 AM XXCoder: didnt you know before you bought em?
12:33 AM Crom_: Thought they did, went back and looked at the listing.. 4GB RAM 32GB MLC Sata module no wifi
12:34 AM Crom_: I have 1 wifi module I can put in...
12:34 AM XXCoder: doh that happens
12:34 AM Wolf__: wired > wifi
12:35 AM XXCoder: once ordered 5 pack of fans, and its 5v and I could only use 12v lol
12:35 AM XXCoder: yep. my room will be wired :D
12:38 AM Wolf__: wifi for guests, throttled to 0.2mbit
12:38 AM Wolf__: =)
12:38 AM XXCoder: theres program that can be flashed to router to generate millions of ssids
12:41 AM Crom_: now to figure out how to unprotect the computer so I can change shit
12:41 AM XXCoder: the thin client?
12:41 AM Wolf__: locked bios?
12:42 AM Wolf__: or worse, bios locked
12:43 AM XXCoder: or everything locked down
12:44 AM XXCoder: my pc for videophones like that. but I found a way to run my own software lol
12:44 AM XXCoder: oddly, by trying to update a driver lol it is only way to browse a folder so far, and it has to be on a cd
12:44 AM XXCoder: so I could say, burn programs to a cd then run it there
12:48 AM Crom_: bios password "Fireport"
12:49 AM Crom_: 32GB SATA module, only can "see" 512MB
12:50 AM XXCoder: geeez
12:51 AM Crom_: trying to boot off a 8GB module
12:51 AM Crom_: booting :)
12:53 AM XXCoder: it may be only 512 mb if it was chinese buy lol
12:54 AM MrHindsight: well thin clients are supposed to be locked down
12:54 AM XXCoder: to users yeah
12:54 AM MrHindsight: or they will mess with it
12:54 AM MrHindsight: hey whats disable NIC mean?
12:55 AM MrHindsight: dunno, but it don't work no more
01:01 AM Wolf__: disable HID, more lols
01:01 AM MrHindsight: Keyboard error, press ctl alt delete to reboot :)
01:02 AM XXCoder: reminds me of trick to get admin password on linux system
01:02 AM XXCoder: make a script, make it su
01:02 AM XXCoder: it records password then pass it on to real su
01:02 AM XXCoder: put it in /usr/bin, it's invisiable to admin
01:03 AM XXCoder: im pretty sure theres protection against that now
01:04 AM MrHindsight: if user xxcoder, then 10000 volts to pants
01:04 AM XXCoder: admin's pants I see. nice
01:05 AM MrHindsight: did you ever try a program called src/usr_intr/axis/scripts/teach-in.py. IIRC this will capture position or something like that.
01:05 AM MrHindsight: for learn or teach mode for LCNC
01:09 AM MrHindsight: what is the open source CAM that most are using?
01:09 AM MrHindsight: has to be open so that I can modify the source
01:09 AM XXCoder: very few of tghat :(
01:10 AM XXCoder: freecad is one of em
01:10 AM XXCoder: interesting script. looks like can make gcode with it, setting locations and such
01:11 AM MrHindsight: what I need to write is an easy to use front end for LCNC control that hides all the g-code from the user
01:12 AM MrHindsight: it won't do any cutting
01:12 AM MrHindsight: it's just LCNC for a cartesian robot
01:12 AM XXCoder: ah was really wondering!
01:12 AM MrHindsight: moves things around, pick-n-place, fluid handling etc
01:14 AM MrHindsight: XYZ moves, pick, place, draw fluid, drop fluid etc
01:14 AM MrHindsight: for the non-programmer
01:14 AM MrHindsight: or like teach mode on a robot
01:15 AM MrHindsight: you move the bot around with the pendant and record the paths
01:15 AM MrHindsight: http://docs.opentrons.com/ is too complicated
01:18 AM MrHindsight: https://github.com/Heeks/heekscnc fork this??
01:18 AM XXCoder: last time I tried that it was buggy as heck
01:19 AM XXCoder: theres apparently 21 forks
01:20 AM MrHindsight: or fork freecad
01:20 AM MrHindsight: well I'm not doing anything fancy
01:20 AM MrHindsight: lots of very linear moves
01:20 AM MrHindsight: can be all straight paths
01:21 AM MrHindsight: https://www.freecadweb.org/wiki/Path_Workbench
01:21 AM MrHindsight: hey fragalot
01:21 AM XXCoder: dont bother with 0.16 with Path
01:22 AM XXCoder: 0.17 has newer version and it works bit differently
01:22 AM XXCoder: #freecad if you wanna ask some questions
01:23 AM MrHindsight: XXCoder: how it works https://youtu.be/G5AmT7ez46c?t=13s
01:23 AM MrHindsight: pretty simple stuff
01:23 AM fragalot: hi
01:24 AM XXCoder: nice
01:24 AM XXCoder: I can imange that being a GRIND
01:24 AM MrHindsight: I want a LCNC version
01:25 AM MrHindsight: they use an Rpi or something duino
01:25 AM MrHindsight: https://www.youtube.com/watch?v=ik_v17EwucU
01:30 AM fragalot: I don't know if LCNC would add any value
01:31 AM XXCoder: "perfectly fit" hah
01:31 AM fragalot: you don't need a huge tool library for pipetting, and you don't need incredible pathing either
01:31 AM XXCoder: no such thing. only "within tol" and "out of print"
01:31 AM MrHindsight: http://docs.opentrons.com/ is too complicated
01:32 AM MrHindsight: and they are limited in computing power when you want to add vision
01:32 AM fragalot: oh yeah.
01:32 AM fragalot: I've started playing with vision at work a little bit on an STM32
01:32 AM fragalot: it's incredible what you can do with limited processing power, really
01:33 AM fragalot: (note: limited being an M7 ARM core at 216Mhz)
01:34 AM MrHindsight: sure we got excited in ~1984 when we could capture a single 525 line video frame in real time on an 8Mhz PC
01:35 AM XXCoder: geez that new engine design is insane
01:35 AM fragalot: what engine?
01:35 AM XXCoder: linked video from me above
01:35 AM fragalot: I don't think I was in the channel yet
01:35 AM XXCoder: its just before i said "perfectly fit hah!"
01:36 AM fragalot: I see MrHindsight linking to that pipette jobber, but no link from you
01:36 AM MrHindsight: yeah no link
01:37 AM XXCoder: bleh
01:37 AM XXCoder: paste faik
01:37 AM XXCoder: https://www.youtube.com/watch?v=cfecW3bGiEs
01:37 AM MrHindsight: engine, engine, engine
01:38 AM XXCoder: I figured a flaw with it. its supposely to be constantly burning. fine. but how does it START it?
01:38 AM MrHindsight: ceratinly has lots of gears :) https://youtu.be/cfecW3bGiEs?t=5m56s
01:39 AM XXCoder: what if it somehows stalls and loses fire, how does it restart?
01:39 AM fragalot: I'm trying to wrap my head around the compression part
01:41 AM Crom: gigabitpower line adapter is working good
01:41 AM XXCoder: he has 2 other videos. im watching jet one. i dont know enough about jets to see fesability of it.
01:43 AM XXCoder: third video is just that engine animating. gears isn rotating.
01:43 AM fragalot: it wouldn't work
01:43 AM XXCoder: not too likely I would think yeah
01:43 AM XXCoder: it MIGHt work, as compressed air engine.
01:43 AM fragalot: meh
01:43 AM fragalot: interesting ideas, both neither are practical
01:43 AM XXCoder: it would need bunch of stuff, now useless, removed.
01:44 AM XXCoder: just inject enough air to make it want to expand pisiton just past the cutoff
01:44 AM XXCoder: repeat
01:45 AM XXCoder: that would allow for far more injectors and exits, making it possibly effecient air engine, better than ones in actual air engine cars
01:45 AM XXCoder: but then so many gears, torque losses
01:46 AM Wolf__: turbo encabulator is much better thing
01:46 AM XXCoder: https://www.youtube.com/watch?v=2fjcJp_Nwvk ?
01:49 AM XXCoder: https://www.youtube.com/watch?v=gcRgRQ3Aqnc LOL hes "stealing" with his own machine
01:49 AM XXCoder: but loks very possible
01:50 AM MrHindsight: XXCoder: does the path workbench in freecad allow you to see the paths as an animation?
01:50 AM XXCoder: yeah. ich is upgrading that but yeah
01:51 AM XXCoder: make a basic block, add basic cut and theres animation show
01:51 AM MrHindsight: XXCoder: so I could put the model of the robot in freecad and then preflight motion
01:52 AM XXCoder: think its limited to 3 axis cartensian machine
01:52 AM XXCoder: could be wrong
01:52 AM MrHindsight: thats all the robot is
01:52 AM XXCoder: could ask in #freecad
01:52 AM MrHindsight: 3 axis cartesian
01:53 AM MrHindsight: have 0.16 installed
01:53 AM MrHindsight: ok so I should update
01:53 AM XXCoder: look for freecad daily
01:53 AM XXCoder: if linux and you added repo
01:54 AM MrHindsight: example project of a robot is already in there :)
01:54 AM XXCoder: oh really
01:54 AM MrHindsight: it's a PUMA
01:54 AM pink_vampire|2: hi
01:54 AM MrHindsight: on Fedora right now
01:55 AM gloops: you can add scripts with freecad, i think they have done some pretty 'advanced' stuff, but it isnt with the standard app
01:55 AM XXCoder: theres still upcoming "assembly" mode
01:56 AM XXCoder: its been upcoming for last 500 years
01:56 AM MrHindsight: I've only used it a few times to look at models
01:56 AM MrHindsight: I use real CAD/CAM :)
01:56 AM MrHindsight: XXCoder: yeah, thats always the story
01:56 AM XXCoder: hind its pretty nice nowdays. .16 is actually usable, and .17 is better. just unstable file format on 0.17.
01:56 AM MrHindsight: Duke nukem
01:58 AM gloops: the thing with these apps, nobody has time to spend on them, someone gets cnc machine, needs cad/cam, tries freecad - it doesnt seem to do this or that, on to the next app the same minute
01:58 AM jesseg: hey guys how's it going?
01:58 AM evilren: no u
01:58 AM gloops: its just like a part for the machine - this motor isnt going to do it, order a new one today
01:58 AM jesseg: I got that LED readout working: https://videoflier.com/movies/1518249346429697019456
01:58 AM jesseg: They'd make *great* dro displays
01:59 AM evilren: jesseg: neat
01:59 AM gloops: excellent jesseg
02:00 AM gloops: could do with some linear travel dro
02:00 AM XXCoder: help nne
02:00 AM XXCoder: me no know nne so sorry lol
02:00 AM XXCoder: hey pink_vampire|2
02:01 AM gloops: even a basic position readout would be useful for checking steppers, at least youd know if you had lost position
02:01 AM XXCoder: you could use few of em
02:01 AM jesseg: XXCoder, hey don't laugh I was trying to figure out how to do M's.. Kind of hard on a 7 seg
02:01 AM jesseg: lol
02:01 AM XXCoder: Mach, part coord
02:01 AM XXCoder: add machine status (estop, pause, running, finished)
02:01 AM XXCoder: :) jesseg
02:02 AM XXCoder: if there is smaller display you could even display what coord it is using.
02:05 AM fragalot: top view touchscreen for rapid moves
02:05 AM fragalot: poke approximate location where you want to start to jog & it rapids there instantly
02:05 AM gloops: i think i am sorted on my dual motor axis, 4200 reliable jog speeds, might get a couple hours today to start getting the z working https://www.youtube.com/watch?v=xf5p-7VZmcs&feature=youtu.be
02:09 AM MrHindsight: https://imagebin.ca/v/3gQc9gMQf3qJ is this your spindle?
02:09 AM MrHindsight: gloops: ^^
02:10 AM gloops: dont underestimate this spindle MrHindsight, it looks small because the machine is big, it has the necessary power
02:11 AM gloops: despite its appearance this is a machine of finesse and accuracy, it isnt for ripping crude holes in stuff
02:12 AM XXCoder: its dc spindle or ac?
02:12 AM MrHindsight: I use this for ripping crude holes https://imagebin.ca/v/2RuHAsYVLA7N
02:13 AM gloops: 800w 3 phase
02:13 AM miss0r: mornin
02:15 AM Wolf__: my tool post grinder for my lathe is 1300w…
02:16 AM miss0r: are we comparing tool post grinders here? because i'd loose that one :D
02:16 AM XXCoder: just tighten that sit up it'll win
02:16 AM Wolf__: lol dremel?
02:17 AM gloops: 800w is fine, the biggest tools are probably 1/4 inch diameter, not going fast, i will get a 1.5kw in good time
02:17 AM miss0r: wolf__: No :D but it is only 250watt
02:18 AM Wolf__: I bet the oversized thing I have would make a nice router spindle
02:18 AM miss0r: https://imgur.com/a/K5RkF
02:18 AM miss0r: It was the only 'small' motor I had laying around when I build it
02:19 AM miss0r: bbl
02:20 AM fragalot: miss0r: the servo looks a bit bigger than I remember!
02:20 AM Wolf__: this is mine https://www.kbctools.com/products/POWER%20@@2f%20AIR%20TOOLS/POWER%20TOOLS%20@@26%20ACCESSORIES/GRINDERS%20-%20ELECTRIC/TOOLPOST%20GRINDERS/8344.aspx
02:21 AM fragalot: my toolpost grinder is a foredom handpiece in a quickchange toolpost holder :P
02:22 AM Wolf__: I didn’t pay that tho lol
02:22 AM Deejay: moin
02:22 AM MrHindsight: Wolf__: how many tool posts do you grind a day?
02:23 AM Wolf__: all of them =) really I haven’t used it yet
02:23 AM Wolf__: still need to make a new tee-bolt for it so I can fit it on the lathe
02:24 AM fragalot: lol
02:24 AM gloops: https://www.youtube.com/watch?v=9MuoS9JlOxU 800w spindle cutting, i used a ryobi 1050w to cut 40mm worktops in one pass with a jig, plenty of power there for wood
02:25 AM Wolf__: I do need to get myself a foredom setup
02:25 AM XXCoder: collect em all!
02:25 AM fragalot: Wolf__: they are utterly fantastic.
02:25 AM gloops: bigger spindle is associated with travel speed
02:27 AM XXCoder: so, how muc for that master pokemon ball
02:29 AM gloops: one oversight maybe with linuxcnc readout with joints, the joints readout - individual joints disappears when the axis are homed, so you get one X position for the 2 motors, it would be useful to still see the individual joints position, to see they are still in sync
02:30 AM MrHindsight: make it so
02:30 AM gloops: no idea how
02:30 AM gloops: no time to learn
02:31 AM XXCoder: gloops: you was really making pokemon ball decal or is it something else?
02:31 AM gloops: that wasnt me heh
02:32 AM XXCoder: oh so you arent tyler?
02:33 AM fragalot: gloops: you can't see if the joints are in sync unless each joint has an actual encoder
02:33 AM fragalot: linuxcnc does not know if it's missed steps on a joint
02:35 AM MrHindsight: open loop steppers?
02:35 AM Wolf__: add encoders on everything
02:36 AM MrHindsight: how mANy counts per rev on the spindle?
02:36 AM fragalot: MrHindsight: even those don't know if the pulley slipped :-)
02:36 AM MrHindsight: pulley?
02:36 AM fragalot: in gloops's case
02:36 AM MrHindsight: ah
02:36 AM Wolf__: then add linear encoders everywhere =]
02:36 AM MrHindsight: don't know what he's got
02:39 AM MrHindsight: custom drill https://youtu.be/dSk40tO8PJs?t=1m44s
02:40 AM MrHindsight: lotsa t-slot
02:40 AM fragalot: can't beat T-slot for quick fabs
02:40 AM fragalot: we use miles of that stuff all day long
02:41 AM fragalot: well.. used to, until we found out that you can subcontract a stainless structure cheaper, lol
02:41 AM MrHindsight: yeah
02:41 AM MrHindsight: I use it for one offs or protos
02:42 AM MrHindsight: https://ibin.co/w800/3i0LDN2s3TZ7.jpg and combine it with standard shapes
02:43 AM gloops: yes that is true fragalot, i dont think there would be any reason for linuxcnc to show different positions for those 2 motors
02:43 AM fragalot: yup
02:43 AM MrHindsight: I thinks the base was $200 of slot
02:43 AM gloops: the diy encoder question is one to which i shall return
02:43 AM fragalot: why would you DIY an encoder?
02:43 AM gloops: because i havent got any?
02:44 AM fragalot: buy a ready made one
02:44 AM fragalot: rotary encoders aren't that expensive
02:44 AM MrHindsight: I know this guy that has some
02:44 AM gloops: oh yeah probably buy the encoder and diy bodge it to show something
02:44 AM fragalot: and you can just use wire wrapped around a pulley to get a cheap linear encoder
02:44 AM MrHindsight: yeah the Omron's are are really cheap now
02:44 AM fragalot: in fact, my roland uses wire pulleys for everything except Z
02:44 AM fragalot: Z is just a little cam
02:45 AM gloops: i was thinking of fitting something to the far end of the screws for a reading, the pulley end is busy enough
02:45 AM fragalot: that works
02:47 AM gloops: first lets get a machine thats cutting though, im just wiring this notorious t6560 up
03:15 AM Califax: Hallo bin neu
03:18 AM Califax: Das war mein erster Versuch der Bedienung. ich suche Verbindung zu dem Herrn der den Youtube Kanal "MAGIG CNC Maschines ". Bin gerade dabei mir eine CNC Fräse zu bauen und suche eine Steuerung wie die aus dem Kanal.
03:18 AM fragalot: Califax: That would be IchGucksLive - but he is not o.... fine.
03:18 AM fragalot: Califax: That would be IchGucksLive - but he is not online at the moment.
03:19 AM XXCoder: https://www.youtube.com/watch?v=GNgH3qFTFIE
03:22 AM fragalot: XXCoder: shame there aren't any oversized handles made of fatwood
03:26 AM XXCoder: oh well
03:35 AM miss0r: fragalot: yeah I had to up the size even more :
03:36 AM miss0r: :P*
03:36 AM fragalot: :)
03:36 AM miss0r: Here we go. I now have a few hours to get a look at building the rest of the spindle
03:37 AM miss0r: but first, a soda & a cigarette
03:42 AM miss0r: I know a guy who also has his own small company. They do safety release valves(service and rebuilding). They have a 2x6m cnc router with a dragknife to make seals in all sorts of materials. He is going to make a bunch of rubber seals for this thing, that fits nicely :]
03:42 AM gloops: 8 wire stepper, wiring up 4 - doesnt matter which pairs i use does it?
03:43 AM fragalot: miss0r: awesome. :D
03:43 AM fragalot: gloops: I would imagine so
03:43 AM miss0r: fragalot: Yeah. I would've done it with o-rings, but I can't fit'em
03:43 AM fragalot: O-rings are not /always/ the best solution
03:43 AM gloops: i want to try one of those spindle-dragnife attachments miss0r, seen them cutting leather they look like they work ok
03:44 AM archivist: gloops, there are two ways of wiring, series and parallel
03:44 AM gloops: well ive found the 4 pairs
03:44 AM archivist: get the wrong pairs and it wont run
03:44 AM miss0r: gloops: I'm not sure you can do that with leather(but what do I know) atleast not the ones that are just dragged along. The guy I know has an oscilating knifehead, so it somewhat 'saws' its way through
03:44 AM fragalot: the oscillating ones rock
03:46 AM gloops: the dragknife that fits in the spindle like a tool depend on the drag for positioning, you need to code for positioning - well a lot of apps do it for you, so that the blade gets time to turn with the movement
03:46 AM gloops: which is a very good explanation
03:46 AM miss0r: yeah, he needed it. The knife blades are tungsten carbide - He mostly cuts steel reinforced carbon(?) mats for those high temperature seals
03:46 AM gloops: archivist so if i just try all the pairs i should find it?
03:47 AM gloops: (which isnt a very good explanation)
03:47 AM miss0r: graphite mats*
03:48 AM gloops: pond liner or roofing rubber, butyl would probably be good for gaskets
03:48 AM fragalot: or, you could just use actual gasket material
03:48 AM archivist: gloops, a scope can find them easily
03:49 AM gloops: only scope ive got is for looking at the moon heh
03:50 AM fragalot: trial and error works too
03:51 AM Wolf__: how about one of them electrical tester things
03:51 AM gloops: thats the dragknife im thinking of https://www.youtube.com/watch?v=r88r3prPhjc just sits in the spindle with the spindle powered off
03:51 AM gloops: to find the pairs you just wire 2 wires together and see if the motor is harder to turn, if not try another
03:52 AM fragalot: still don't know which pair is matched with which other pair though on an 8wire
03:53 AM gloops: if i leave pair A wired to the driver, and try all the other 3 pairs, ive got to find a match
03:53 AM fragalot: yup
03:53 AM archivist: you can measure the ac volts join two wires from two pairs, measure across the open pair of wires, some ac or none
03:53 AM XXCoder: gloops: saw that theres cheap drag cutter dumping into ebay
03:53 AM XXCoder: wanted to grab one for hell of it, and conversion to linuxcnc
03:53 AM XXCoder: but nahh
03:54 AM XXCoder: no room, and lack of skills lol
03:54 AM gloops: XXCoder if you can get one worker with the router and have easy software for the dragging, i suppose it could be a lucrative attachment, just takes standard stanley blades
03:55 AM pink_vampire|2: gloops: there is better knife for drag knife
03:55 AM gloops: worker = working
03:55 AM archivist: gloops, http://www.piclist.com/techref/io/stepper/wiresmeterbattery.htm
03:55 AM XXCoder: https://www.youtube.com/watch?v=YqvgA1P5hWg
03:55 AM XXCoder: making of drag knife
03:56 AM pink_vampire|2: no need to make
03:56 AM XXCoder: lol they have porinted prototyoe
03:56 AM pink_vampire|2: just get the cb09 blade on ebay for 2$ each and 5$ for the holder
03:57 AM pink_vampire|2: https://www.ebay.com/itm/US-Graphtec-CB09-Blade-Holder-blades-for-Vinyl-Plotter-Cutter-30-45-60-blades-/172016793628
03:58 AM gloops: just to clarify my intention, i can wire an 8 wire stepper using only 4 wires?
03:58 AM archivist: use all 8
03:59 AM Wolf__: lol same drag knife setup the scrapbooking cutters use
03:59 AM gloops: whats the advantage of using all 8?
04:00 AM archivist: you get full torque
04:01 AM gloops: so i need 4 pairs then 2 matching pairs
04:01 AM pink_vampire|2: with the cb09 60 deg can cut 0.45mm minimum radius
04:01 AM archivist: yes
04:02 AM XXCoder: interesting
04:03 AM pink_vampire|2: it is also carbide blade so it will last much much longer
04:04 AM Califax: Hallo fragalot: Danke für Info :) muss ich halt warten bis IchGucksLive wieder online ist. Thanks
04:05 AM miss0r: pink_vampire|2: Have you formulated a plan? :)
04:05 AM miss0r: fragalot: Transferring code to the cnc now - fingers crossed
04:06 AM fragalot: WHY ON EARTH does this laptop continue to go to sleep and/or disable power to the wifi module even though all of the related settings are disabled.
04:06 AM miss0r: fragalot: Transferring code to the cnc now - fingers crossed
04:06 AM pink_vampire|2: miss0r: about?
04:06 AM miss0r: pink_vampire|2: About the lathe tool wedge clamps
04:06 AM fragalot: miss0r: you still need to make parts?
04:07 AM miss0r: fragalot: The rear most cover, to enclosure the servo in a waterproof seal
04:07 AM fragalot: do you have a tiny opening for a temperatuer probe? :P
04:07 AM miss0r: I even have 3 stainless IP68 cable glands to install there
04:08 AM fragalot: overkill, love it
04:08 AM miss0r: I'm hoping the water coolant already in the spindle housing will help
04:08 AM XXCoder: there is no overkill. just fire and reload
04:08 AM pink_vampire|2: miss0r: no i didn't, i was sleeping
04:08 AM miss0r: I'm hoping this will allot it to be used sompletely submerged
04:08 AM miss0r: great :]
04:08 AM miss0r: with a c...
04:09 AM miss0r: and a y...
04:09 AM miss0r: What the hell!
04:09 AM fragalot: lol
04:09 AM miss0r: no a w :o
04:09 AM fragalot: the buttons are just so close together
04:09 AM miss0r: I don't know what is going on
04:09 AM miss0r: hehehe this g code is pushing the limits of my whooping 64kbyte memory
04:10 AM fragalot: should have enabled smoothing :P
04:11 AM fragalot: or use a better post processor to generate more efficient code
04:11 AM XXCoder: using g2 and g3?
04:11 AM miss0r: yeah
04:11 AM XXCoder: because curves using g1 really explode the gcode
04:11 AM XXCoder: 3d printers does not lol
04:11 AM miss0r: I wrote this damn post processor my self. I WILL NOT OPTIMIZE IT!
04:12 AM fragalot: miss0r: hook up external RAM then to your controller & load the file in a ramdisk
04:12 AM miss0r: code transfer complete. Will go do the deep - fingers crossed
04:12 AM miss0r: fragalot: hahaha, now that would be complicated
04:12 AM fragalot: :-)
04:13 AM miss0r: I 'could' buy a 1mb expansion card: http://www.ersatzteilcenter.net/nach-maschinenhersteller/graziano/400/4022-226-2340-speicherkarte
04:13 AM miss0r: But the price is insane
04:14 AM miss0r: NOW to the milling bbiab
04:14 AM DaViruz: no drip feed?
04:15 AM miss0r: no drip feed
04:17 AM DaViruz: :(
04:19 AM XXCoder: wd40 spray
04:24 AM fragalot: https://www.youtube.com/watch?v=a_-93snwiqA I wish I knew about this neat little trick when I was still traveling a lot for work
04:25 AM pink_vampire|2: google know about me too much]
04:26 AM pink_vampire|2: miss0r: https://i.imgur.com/DI5gP5E.png
04:26 AM pink_vampire|2: this is why i have a problem to find a good design
04:27 AM fragalot: lmao
04:27 AM XXCoder: ah anklebreaker shoes
04:27 AM XXCoder: I wish those would die but fasion will never allow it to doe
04:27 AM XXCoder: *die
04:28 AM fragalot: pink_vampire|2: https://imgur.com/a/PJrwh
04:28 AM pink_vampire|2: did you saw the key words?
04:28 AM fragalot: helps if you add toolholder rather than just holder
04:28 AM XXCoder: you may want to try other search engine a second
04:29 AM XXCoder: like duckduckgo
04:29 AM XXCoder: its similiar with google only they dont do tracking and user matching
04:29 AM XXCoder: so you get better results
04:29 AM pink_vampire|2: google is very chauvinist
04:30 AM XXCoder: mine is all lathe and machining stuff pictures
04:31 AM Wolf__: same here
04:31 AM pink_vampire|2: shoes vs lathe tools..
04:31 AM fragalot: cork shoes too
04:31 AM Wolf__: but I never search/visit any fashion sites…
04:32 AM Wolf__: try dumping your tracking cookies…
04:32 AM fragalot: sadly that lone isn't enough anymore
04:33 AM Wolf__: or better wording
04:33 AM XXCoder: pink_vampire|2: could add negative terms
04:33 AM XXCoder: like blah blah -shoes -lady
04:33 AM Wolf__: -shoes
04:33 AM pink_vampire|2: i love shoes
04:33 AM XXCoder: removes all shoes and lady words so you get result you want
04:33 AM Wolf__: then why are you complaining
04:34 AM XXCoder: sure but not during searching for tooling?
04:34 AM pink_vampire|2: https://cdn.shopify.com/s/files/1/2365/0149/products/1in_OD_Tool_Holder_Wedge_3_936904d7-5134-4f6a-87da-e2c0d31426b4_480x480.jpg?v=1511484712
04:34 AM pink_vampire|2: how it made?
04:35 AM XXCoder: with mill im sure
04:35 AM Wolf__: shit wording btw, when I put in swiss wedge gang holder, first dozen images were tool holding, rest women shoes for me
04:35 AM fragalot: pink_vampire|2: mill out pocket of block, insert shim with same angle as wedge, then add in wedge to clamp
04:35 AM XXCoder: one screenful down before I see first shoe
04:35 AM XXCoder: slowly increasing
04:35 AM fragalot: another alternative could be to make the wedges like gibs
04:36 AM fragalot: with just 1 screw to tighten & release
04:36 AM pink_vampire|2: so it is a wedged shim
04:36 AM fragalot: yes
04:36 AM pink_vampire|2: aluminum will be ok?
04:36 AM pink_vampire|2: or it is must be steel?
04:36 AM fragalot: for that size tool, sure
04:38 AM pink_vampire|2: mm
04:38 AM Wolf__: for what you are going to be trying, aluminum will work fine, you’ll be throwing the workpiece out of the chuck before the tooling moves
04:39 AM pink_vampire|2: what angle the wedge need to be?
04:40 AM Wolf__: enough to wedge tooling
04:40 AM fragalot: not critical, the stepper the more clamping pressure, but more travel
04:40 AM Wolf__: ...
04:40 AM fragalot: go for 12°
04:40 AM fragalot: I like that number;
04:40 AM pink_vampire|2: 12 from each side?
04:40 AM * Wolf__ thinks 13°
04:40 AM fragalot: pink_vampire|2: no just one
04:40 AM fragalot: you want the part touching the tool to be flat
04:40 AM fragalot: square*
04:41 AM pink_vampire|2: https://cdn.shopify.com/s/files/1/2365/0149/products/1in_OD_Tool_Holder_Wedge_3_936904d7-5134-4f6a-87da-e2c0d31426b4_480x480.jpg?v=1511484712
04:41 AM pink_vampire|2: is is not flat
04:41 AM Wolf__: its a photo
04:41 AM fragalot: the part touching the tool is square
04:41 AM Wolf__: at a angle
04:41 AM Wolf__: tool is square shank
04:42 AM Wolf__: slot is square sides
04:42 AM fragalot: L\ <- like that. :P
04:42 AM fragalot: and then a spacer like \|
04:43 AM fragalot: [] L\ \| [] = tool, L\ = wedge with screws, \| = spacer
04:43 AM Wolf__: https://www.ebay.com/itm/Okuma-LU15-CNC-Lathe-Tool-Holder-Blocks-Turret-Face-Wedge-Clamp-for-1-Square-/172406984054
04:43 AM fragalot: lol it's the exact same picture
04:43 AM Wolf__: holy over complicating something simple
04:44 AM fragalot: hey if those things sell for that price I think i'm in the wrong business
04:44 AM Wolf__: has oakum in the name
04:44 AM pink_vampire|2: so the holes for the screws are over sized?
04:45 AM fragalot: pink_vampire|2: pockets
04:45 AM fragalot: the head is recessed to maintain the lowest possible clearance on the toolchanger
04:45 AM Wolf__: I’l planning on making cat excavator pins, just turned carbon steel w/ cross pin hole, $100 each
04:45 AM pink_vampire|2: but as the wedge go deeper the hole move sideways
04:45 AM fragalot: Wolf__: i'm fairly sure they're at least case hardened
04:45 AM Wolf__: actually I bet its just clearance hole
04:45 AM Wolf__: nope
04:46 AM Wolf__: can cut it with a file
04:46 AM fragalot: pink_vampire|2: not enough to worry about
04:46 AM pink_vampire|2: mmm
04:46 AM Wolf__: thats the first thing I thought when I was looking at the ones for the new excavator my buddy got
04:46 AM fragalot: pink_vampire|2: it can't move closer to the tool than the square shoulder anyway
04:47 AM fragalot: it only needs to move a few thou to clamp hard
04:47 AM pink_vampire|2: i see what you mean
04:47 AM fragalot: Wolf__: ha, in that case,.. go for it! small customer base, but they get wrecked a lot
04:47 AM Wolf__: the slots for the tools on the turret are fixed size, so the wedge block only has to move <0.001” probably to clamp
04:48 AM pink_vampire|2: so if the tool is 1/4" by 1/4" what side of wedge i need?
04:48 AM Wolf__: yeah, we got quick change tool “holder” for the buckets so needed 5 sets of pins
04:48 AM pink_vampire|2: so slot is 1/4" deep?
04:48 AM Wolf__: 10” wedge
04:48 AM Wolf__: if slot is 10.15”
04:48 AM fragalot: pink_vampire|2: just draw it up in CAD and see what looks good
04:49 AM Wolf__: 10.25”
04:49 AM Wolf__: typo...
04:49 AM pink_vampire|2: ok.
04:49 AM fragalot: for small low pressure tooling like this there's no real magic
04:49 AM fragalot: if it looks like it might work, it will work fine :-)
04:49 AM Wolf__: are you planning production run of turning with the mill or something?
04:49 AM pink_vampire|2: hehe
04:49 AM Wolf__: like 20 parts or something
04:50 AM gloops: ive just realised something slightly confusing, none of my drivers step/dir signals are grounded
04:50 AM Wolf__: lol
04:50 AM Wolf__: power to them has ground
04:50 AM gloops: how can that even work?
04:50 AM fragalot: lmao
04:51 AM Wolf__: system ground looping somewhere
04:51 AM fragalot: the drivers probably have them tied to ground internally somewhere
04:51 AM gloops: now i see it all!
04:51 AM archivist: they are in series with the drivers and opto isolated
04:51 AM fragalot: for EMI reasons, not to be relied on
04:51 AM gloops: i had them all connected to a block - the block is not connected to bob, i remember taking a loose bit of wire off the other day
04:51 AM archivist: so actually PC ground via the bob
04:52 AM fragalot: lol.µ
04:52 AM gloops: je..s that could have been the trouble ive been having
04:52 AM fragalot: yup
04:52 AM Wolf__: possible lol
04:53 AM archivist: the opto is on an open collector to 5v
04:53 AM gloops: ill sort that later got to leave it now, i was really confused - first time i ran this axis it seem bursting with power, after that nothing but trouble and slow, thats about the time i saw what i thought was an offcut of wire i just took it out
05:22 AM gloops: just took the time to connect that ground block to bob pcc ground, all seems to run well with vfd ON now, my 8 wire stepper works as well, result!
05:28 AM gloops: next session, fit motor to z, get spindle working again
05:30 AM dan3wik is now known as dan2wik
06:02 AM pink_vampire|2: the HF lathe tools work very nice on steel
06:03 AM fragalot: :-)
06:05 AM pink_vampire|2: https://i.imgur.com/G0HSwgr.jpg
06:13 AM fragalot: any issues still with the tool slipping?
06:16 AM pink_vampire|2: no, i just hang my whole body weight on the vise handle when i close it
06:16 AM fragalot: lol
06:17 AM pink_vampire|2: and i have a problem with making the holder
06:17 AM fragalot: oh?
06:18 AM pink_vampire|2: the stoke is heavier then me..
06:18 AM fragalot: ?
06:18 AM pink_vampire|2: so i need to ask for help just to lift it from the floor to the power hacksaw
06:19 AM fragalot: ah the stock
06:19 AM pink_vampire|2: stock* yeah
06:19 AM fragalot: I'd offer to help,but I don't think that'd do much good, lol
06:20 AM * fragalot hands pink_vampire|2 a manual hacksaw
06:20 AM pink_vampire|2: and i need to get m3 tap
06:20 AM fragalot: pink_vampire|2: get a good quality set if you buy taps
06:20 AM pink_vampire|2: 1.5" steel bar with manual saw.. that will take a while..
06:20 AM miss0r: fragalot: Getting there getting there. Now I've machined the last part. Now I just need to drill'n tap the other end of the spindle housing & shorten the motor coubling
06:21 AM fragalot: pink_vampire|2: do NOT be tempeted by the cheap sets, they are absolute garbage.
06:21 AM fragalot: miss0r: w00t.
06:21 AM pink_vampire|2: i want to get irwin
06:23 AM miss0r: fragalot: https://imgur.com/a/XxU1N
06:24 AM fragalot: I didn't even know irwin made taps
06:24 AM pink_vampire|2: miss0r: look amazing!!
06:24 AM fragalot: miss0r: how are you going to seal the 3 wries going through that one gland?
06:24 AM miss0r: fragalot: I'm not :) They will be soldered to a cable inside the housing. They were just in the way when I had to test fit
06:24 AM fragalot: also, I'm absolutely LOVING how robust that assembly looks,... and it's hiding a cheap hobby RC servo.
06:25 AM miss0r: pink_vampire|2: Thanks
06:25 AM miss0r: fragalot: Need I remind you I payed for the expensive shipping?
06:25 AM fragalot: hahahaha
06:25 AM pink_vampire|2: miss0r: what it is going to me?
06:26 AM miss0r: going to be?
06:26 AM pink_vampire|2: the part
06:27 AM fragalot: pink_vampire|2: this is a set that I really like that's quite reasonably priced: https://www.esmax.nl/Gereedschap-Accessoires/Draadsnijgereedschap/Draadsnijsets/Machinetappenset-blind-V%C3%B6lkel/machinetapset-35deg-rsp-m-3-12-s-volkel.html
06:27 AM miss0r: That is the top part of the electrode spindle assembly
06:27 AM fragalot: note these are "blind taps"
06:27 AM miss0r: Might I recommend thrmer taps ?
06:27 AM fragalot: You may.
06:27 AM miss0r: consider it recommended
06:28 AM fragalot: I usually use a mix of volkel, dormer & phantom
06:28 AM fragalot: and a lot of goodie oldies that have the logo worn off
06:29 AM fragalot: miss0r: thürmer does indeed seem to be very competitively priced!
06:29 AM miss0r: I keep 5 sets of taps. One for steel, one for stainless, one for alu, one for cast iron & one for soft metals/plastics. All thrmer
06:29 AM miss0r: and its good quality in my opinion
06:30 AM fragalot: same, except there is a 6th set that have the drill bits brassed
06:30 AM fragalot: and there is a 7th "bucket" of loaner taps in case someone asks for one, lol
06:31 AM miss0r: I love how all the parts of this spindle comes apart with a suction sound, loke popping a bottle of wine :D
06:31 AM fragalot: awesome
06:31 AM miss0r: I guess I've done something right on this build
06:32 AM miss0r: meh. I also need to machine two flats on the end of the spindle shaft, just above the ER11 nut, for tensioning
06:32 AM fragalot: miss0r: does this say "dilute with water" on the bottle? http://www.thurmer.com/products/281-thuumlrmer-olie/45658-thuumlrmer-drilling-oil-1-liter/
06:32 AM fragalot: I need some water soluable oil, might as well order it from them whilst I order some other bits & pieces to check them out
06:32 AM miss0r: yep
06:33 AM miss0r: well, it says 'water diluteable'
06:33 AM fragalot: miss0r: the most important question, have you TESTED the spindle yet with that motor?
06:33 AM miss0r: fragalot: ofcourse I have! I'm nowhere near as stupid as I look :]
06:34 AM fragalot: I don't know what you look like, so you'll have to forgive me for assuming :-)
06:34 AM miss0r: hahaha
06:34 AM miss0r: It has enough torque to turn it and then some
06:34 AM miss0r: Otherwise I would come for you ! :D
06:34 AM fragalot: ._.
06:35 AM miss0r: nah.. I owe you one for the idea ;)
06:38 AM fragalot: that's alright. :-)
06:43 AM fragalot: thurmers' carbide tipped drill bits are like half the price of the phantoms I use now
06:43 AM gloops: pink_vampire get some pull lifts https://www.ebay.co.uk/itm/750kg-Pull-Lift-Lever-Hoist-Ratchet-Winch-1-5-Mtr-Drop-REF-6575-A/273050398368?
06:44 AM gloops: didnt you ever work down a pit
06:44 AM pink_vampire|2: gloops: there is better way
06:44 AM fragalot: get someone else to do it?
06:45 AM pink_vampire|2: there is also the option of voice commands
06:45 AM gloops: pull lifts are good for lifting, dragging, pulling anything, pulling trees down, or up
06:47 AM pink_vampire|2: alexa cut me stock material
06:47 AM pink_vampire|2: for me*
06:47 AM fragalot: do it the this old tony way
06:47 AM fragalot: karate chop
06:47 AM pink_vampire|2: lol
06:50 AM fragalot: miss0r: €30 shipping from thurmer >.>
06:51 AM pink_vampire|2: https://i.imgur.com/vxtwdeT.png
06:51 AM pink_vampire|2: i think it is not going to work with the wedge
06:51 AM fragalot: why not?
06:52 AM pink_vampire|2: it only secure in one direction
06:52 AM pink_vampire|2: so it can slip
06:52 AM fragalot: I'm fairly sure that if it works for industrial machines, it will work for your 1/4" tools
06:52 AM pink_vampire|2: look at the arrow
06:53 AM fragalot: and you're making it out of aluminium, which is fairly grippy material when clamping
06:53 AM pink_vampire|2: i'm going to make it from steel
06:53 AM fragalot: pink_vampire|2: if you're worried about it coming out, add a little toe-clamp on top :P
06:53 AM fragalot: I honestly doubt it will, but if it helps you sleep at night
06:54 AM pink_vampire|2: maybe to cut a taper in to the holder
06:55 AM fragalot: I think you're overcomplicating it
06:55 AM fragalot: all of my toolholders in my lathe use just little M8 setscrews to hold the tools in place
06:56 AM fragalot: and the shorter HSS pieces are only clamped with 2 screws
06:57 AM pink_vampire|2: mmm
07:10 AM miss0r: Okay, Now everything is drilled and tapped
07:10 AM fragalot: i'm conflicted
07:10 AM fragalot: I want to get a little engine hoist for my shed
07:10 AM fragalot: but I don't know where the hell to put it when it's not in use
07:10 AM miss0r: I Just need to shorten the motor coubling & grind down the head on some 3mm allen head bolts. (I need to take 0.1mm diameter on them, and reblue them). Also I need to shorten the treads on them by 4mm
07:10 AM archivist: some fold up
07:11 AM fragalot: archivist: yeah I know, but it still takes up space
07:11 AM miss0r: But that will have to wait for later. I have to go be a family guy in a sec
07:11 AM jthornton: fragalot: mine folds up
07:11 AM fragalot: even folded that's still usually 60x30cm
07:11 AM archivist: fragalot, I dont have one but jack and pack and roller stuff about
07:12 AM archivist: short scaffold pole runners
07:12 AM * phipli doesn't like cutting acrylic
07:12 AM * fragalot looks into scaffold poles
07:13 AM fragalot: phipli: why not? with the right cutter & feed it cuts like magic... The only downside is that the chips are bloody static loaded and stick to everything
07:13 AM Tom_L: 15F with a thin layer of ice
07:13 AM archivist: phipli, flatten the cutting edge like you would for brass
07:14 AM miss0r: phipli: and use conventional milling instead of climb milling, makes the burr alot less
07:14 AM miss0r: I will see you guys later
07:15 AM Tom_L: who should i look for?
07:20 AM pink_vampire|2: Tom_L:
07:21 AM pink_vampire|2: why did you make the spray can holder?
07:21 AM Tom_L: it's a part for somebody
07:22 AM pink_vampire|2: cool
07:22 AM Tom_L: the machine has to earn it's keep ya know
07:23 AM phipli: fragalot : I don't do enough cutting to have worked out what the right cutter, feed and speed are...
07:23 AM phipli: also I've not cut any for long enough that I've forgotten what I did last time :(
07:23 AM Tom_L: phipli, there are chip load calculators online
07:23 AM fragalot: phipli: last acrylic I cut I just used a 3flute 6mm endmill @ 3000RPM and a fairly fast manual feed just looking at the chips coming out.
07:24 AM Tom_L: acrylic sucks to cut
07:24 AM Tom_L: black is horrible
07:24 AM fragalot: the results were very good, but I did not approach it from a very scientific pov. :P
07:24 AM Tom_L: clear, not as bad
07:24 AM Tom_L: use a mist spray to keep it cool
07:24 AM Tom_L: or it'll just clog up your cutter
07:25 AM * phipli does not have a spray
07:25 AM fragalot: air blast works OK too
07:25 AM Tom_L: i used a spray bottle on my sherline
07:25 AM Tom_L: ya just gotta keep things cool
07:25 AM * phipli has to stand next to the thing with a piece of broken pcb poking the tool everytime something sticks to it
07:25 AM Tom_L: and keep the cutter movin
07:26 AM Tom_L: with real sharp cutters
07:26 AM phipli: single flute?
07:26 AM Tom_L: i used 2 flute
07:27 AM Tom_L: http://www.onsrud.com/plusdocs/Doc/index.html?model.code=FeedSpeeds
07:27 AM Tom_L: http://www.onsrud.com/files/pdf/2012%20LMT%20Onsrud%20Production%20Cutting%20Tools%20Hard%20Plastic.pdf
07:30 AM phipli: cheers folks
07:30 AM jthornton: yea I finally got my RPi back running the coop I think
07:30 AM pink_vampire|2: what was the problem?
07:31 AM Tom_L: i think he had a log jam
07:31 AM jthornton: df reported /dev/boot at 100% and I could not clear it so I started from scratch
07:31 AM jthornton: and used a 32GB SD card this time
07:35 AM phipli: jthornton, were you saving all the pictures locally?
07:39 AM jthornton: no
07:44 AM IchGucksLive: hi
07:44 AM IchGucksLive: so we lost the savest Gold metal we had to the USA
07:46 AM IchGucksLive: hi fenugrec
07:46 AM fenugrec: IchGucksLive, morn'
07:47 AM IchGucksLive: fenugrec: quite cold up there in the North
07:47 AM fragalot: hey IchGucksLive - someone was looking for you earlier today
07:48 AM IchGucksLive: let me see the log
07:48 AM fenugrec: actually a very comfortable -6C today, but it does get colder
07:49 AM fenugrec: plus, cleaning out the disgusting coolant tank of my cold saw is keeping me nice and warm
07:49 AM fragalot: haha
07:50 AM IchGucksLive: in Germany TÜV wont let you be nice and warm
07:51 AM fenugrec: second item on my cleaning list is the coolant tank on my lathe; that one still has a few L of lumpy, viscous oil that I'm not sure how I'm going to pump out (drain plug is too high, pump inlet is above the remaining level)
07:51 AM fenugrec: what would #linuxcnc use - syringe? vacuum pump ? siphon ?
07:51 AM fragalot: siphon may not work if it's that clumped up
07:51 AM fenugrec: that's what I think too
07:51 AM fragalot: I would probably cheat & use a wet&dry vacuum with a bucket in-line
07:52 AM fragalot: (bucket with lid, pop 2 hoses in the lid)
07:52 AM fenugrec: hmm, the bucket lid seal wouldn't be great but it might be sufficient indeed
07:52 AM fragalot: it doesn't have to be a perfect seal
07:53 AM fragalot: heck, one of my dust collectors just has a plywood lid, lol
07:53 AM fenugrec: right, and I'd prefer not getting of that vile stuff into the vac
07:53 AM fragalot: some may sneak past, make sure to put a bag in that you don't mind throwing out
07:54 AM fenugrec: amazingly, both machines have probably > 20 year old sludge, but they don't stink that much
08:23 AM Loetmichel: plywood is a lot more surdy than plastic. and for the seal: none needed, a vacuum has so much volume that a bit of blowby dosent matter
09:13 AM JT-Shop: ouch a 79g double yolk
09:39 AM IchGucksLive: freecad REAL Mashine CRC from Now https://youtu.be/I91GxAHWUS8
09:39 AM IchGucksLive: im off LATER
09:41 AM gloops: i knew youd sort it Ichs
10:12 AM gloops: this spindle would have been a lot easier if the manual had the same vfd pins as the vfd it came with
10:23 AM pink_vampire|2 is now known as pink_vampire
10:42 AM fragalot: it's always a good sign when building electrical panels & all the holes except for 1 line up perfectly
10:42 AM fragalot: that one hole not lining up can be easily proven by the 2 files I broke. >.<
10:43 AM JT-Shop: your having too much fun
10:43 AM phipli: got the acrylic cut
10:43 AM phipli: actually quite pleased - the first test cut worked well enough
10:44 AM fragalot: JT-Shop: :-)
10:54 AM gloops: i wonder how stair lifts are made, the ones you sit on to ride up stairs
10:54 AM gloops: some good linear motion parts there maybe
10:57 AM JT-Shop: I went to an auction once the old geezer made his own chair lift as well as a bunch of other stuff
10:57 AM gloops: this one is chain drive https://www.ebay.co.uk/itm/Stairlift/263481683316?
10:57 AM archivist: some have a rack that the motor climbs
10:57 AM JT-Shop: his basement was full of metal working machines
10:59 AM gloops: well, you have got a drive system, motors, probably a gantry section and bearings
10:59 AM gloops: selling for ten bob on ebay
11:05 AM gloops: 50nm motor - is that a servo ??? https://www.ebay.co.uk/itm/Stannah-TW03-motor-to-fit-stairlift-model-600si-Used/322849078543?
11:06 AM gloops: something on the end, encoder maybe
11:08 AM pink_vampire: http://www.khabarfeed.com/humor/11-real-struggles-of-girls-with-long-nails/ 12 become a machinist
11:09 AM fragalot: standard motor, brake, gloops
11:09 AM gloops: ahh
11:09 AM gloops: ah yeah 3nm on the end
11:09 AM gloops: so we cant control those
11:12 AM gloops: someone probably died on it anyway
11:14 AM gloops: Hiwin parts https://www.ebay.co.uk/itm/meditek-stairlift-power-swivel-motor/192448235268?
11:14 AM pink_vampire: gloops: it's look like an actuator
11:15 AM gloops: its the motor for the chair swivel
11:15 AM pink_vampire: chair swivel??
11:16 AM Tom_L: does it have a dump bucket too?
11:16 AM gloops: yes on the chair, you can swivel it round to get on, then straighten up again
11:16 AM gloops: theres some parts on these, worm gearboxes and stuff, rack and pinions
11:17 AM gloops: Tom no but washable clip on seat cover
11:20 AM XXCoder: good morning
11:21 AM pink_vampire: hi XXCoder

11:22 AM XXCoder: hows things
11:22 AM pink_vampire: i got the stock material out
11:22 AM pink_vampire: ans i need to cut it and make 4 corners
11:23 AM pink_vampire: and also need to make cover for limit switch
11:24 AM XXCoder: cool :)
11:25 AM XXCoder: https://www.youtube.com/watch?v=95-SGhIeA9k long distance jumper cat
11:26 AM gloops: mainly been doing other stuff, got z motor working though and in place, just needs connector looking at
11:27 AM pink_vampire: gloops: how far are you from making chips?
11:28 AM gloops: pink_vampire not that far at all but got other stuff to do atm, another free day should see it all functional
11:29 AM gloops: then general setting up properly, no cutting board yet all that stuff, but so far so good
11:29 AM gloops: needs full wiring change
11:30 AM pink_vampire: why do you need to change the wiring?
11:31 AM gloops: i just wired it up with any old wire to get it working, ive got some shielded stuff coming, should have had it a week ago but coming this week now
11:32 AM gloops: im a bit more relaxed about the time now, ive seen the parts working that i wasnt sure about, it is going to work, another week or 2
11:38 AM * fragalot wonders what % of users here are just log-bots
11:39 AM archivist: 3% ish
11:47 AM gloops: net xenable => parport.0.pin-17-out < that is E stop?
11:47 AM fragalot: "x enable"
11:47 AM gloops: i dont think its the x axis
11:48 AM gloops: pin 17 is the relay i think
11:50 AM pcw_home: xenable is a signal name it might mean "buy more cheescake"
11:50 AM fragalot: cheesecake!
11:50 AM IchGucksLive: hi all
11:50 AM pcw_home: you need to see what drives it
11:50 AM fragalot: hey IchGucksLive, just in time, apparently gloops is buying us all cheesecake!
11:51 AM IchGucksLive: i like Schwarzwälder moe
11:51 AM IchGucksLive: net xenable => parport.0.pin-14-out
11:51 AM gloops: Ichs my old german friend
11:52 AM gloops: what is xenable referring to? e-stop?
11:52 AM IchGucksLive: if you need estop use 16
11:52 AM gloops: right
11:52 AM IchGucksLive: F1 Mashine on
11:52 AM gloops: 14 is pwm
11:52 AM IchGucksLive: #17 is for M3
11:52 AM gloops: 17 is relay right?
11:52 AM IchGucksLive: yes
11:53 AM IchGucksLive: isolation for VFD
11:53 AM gloops: ill move xenable to 16 then, just so it has a pin
11:53 AM IchGucksLive: you need to enable the stepgens
11:54 AM IchGucksLive: aand or pid also
11:54 AM gloops: net spindle-cmd-rpm => pwmgen.0.value

11:57 AM gloops: yes i get that thanks
11:57 AM IchGucksLive: net xenable axis.0.amp-enable-out => stepgen.0.enable
11:58 AM gloops: what does that do?
11:58 AM archivist: gor
11:58 AM archivist: high power enable
11:58 AM IchGucksLive: it shoudt be set by the wizard
11:58 AM archivist: ignore if not powering down the amps
11:59 AM gloops: net xenable joint.0.amp-enable-out => stepgen.0.enable
11:59 AM gloops: got that in each joint
11:59 AM gloops: yes spindle was allocated in stepwizard, but i used the wrong pins, its ok ill change the pins and see what happens, might work on that
12:00 PM IchGucksLive: NO keep that
12:00 PM * fragalot thinks this may go a lot faster if gloops just pastes the whole file on a pastebin website for Ichs to edit
12:01 PM gloops: net spindle-cw => parport.0.pin-14-out

12:01 PM gloops: net xenable => parport.0.pin-17-out
12:01 PM gloops: its only that that needs changing
12:01 PM gloops: cw needs pin 17
12:02 PM gloops: pwm needs pin 14
12:02 PM gloops: xenable, lucky dip
12:02 PM IchGucksLive: Gloops if you only USE M3 use Spindle-on NOT net spindle-cw
12:03 PM IchGucksLive: net spindle-pwm => parport.0.pin-01-out

12:10 PM miss0r: fragalot: IT SPINS !
12:10 PM IchGucksLive: miss0r: what hapens if it turns
12:11 PM miss0r: Something about pandoras box being opened.. That old chinese man was hard to understand
12:11 PM gloops: so using pin 1 for pwm
12:12 PM gloops: thats marked on my board
12:12 PM fragalot: miss0r: I never expected otherwise. :D :D
12:13 PM IchGucksLive: im making a video so please no post ;-)
12:14 PM miss0r: I'm just gonna run it for 30 minuts non stop now, and see if it lets the ghost out
12:15 PM fragalot: miss0r: do you have a temp probe on the servo?
12:15 PM miss0r: I'm just gonna use my sense of smell I think
12:16 PM fragalot: lol ok
12:16 PM fragalot: it's not like it's under high load
12:16 PM miss0r: While I send an invoice or two
12:16 PM miss0r: well... Thoes axle seals are somewhat tight
12:19 PM fragalot: miss0r: those should wear in by the 3rd servo
12:19 PM miss0r: hehe
12:28 PM IchGucksLive: Video Done
12:29 PM IchGucksLive: hi chupacabra
12:31 PM IchGucksLive: chupacabra: did you see the mountans today or clouds
12:44 PM miss0r: fragalot: Still running :D yay!

12:46 PM SpeedEvil: https://www.youtube.com/watch?v=67lSYypSbfk - cutting sodium with a waterjet
12:47 PM IchGucksLive: waterjet are cool but pricie
12:47 PM IchGucksLive: dirty
12:47 PM gloops: i wouldnt trust myself with a waterjet
12:47 PM SpeedEvil: IchGucksLive: Indeed.
12:47 PM gloops: you are naturally cautious with a sharp tool spinning, or a flame
12:47 PM SpeedEvil: I've idly wondered about an intensifier, driven by ten cheap pressure washers.
12:47 PM IchGucksLive: BUt if yu got one you are the king in town
12:47 PM fragalot: SpeedEvil: they do work from what I hear
12:48 PM IchGucksLive: im off BYE
12:48 PM gloops: water - you could just put your hand under it and your fingers are gone
12:48 PM IchGucksLive: GN8
12:48 PM gloops: night
12:48 PM SpeedEvil: fragalot: one pressure washer (equivalent) is very inefficient, because the power isn't high enough, and the amount of grit used per cut, and the speed is both terrible.
12:48 PM fragalot: I never said it worked /well/
12:50 PM holzjunkie: guten abend allerseits
12:50 PM SpeedEvil: fragalot: I was wondering for enough to get >5kW or so of hydraulic power. Where they start getting interesting
12:52 PM fragalot: Hello holzjunkie
12:53 PM holzjunkie: hello Fraga
12:54 PM holzjunkie: sorry i´m in the wrong channel today
12:54 PM holzjunkie: in the monemt I´ve got problems with Freecad
12:55 PM fragalot: you may want to try #freecad
12:55 PM holzjunkie: i´ve already done thx
12:55 PM holzjunkie: bye till the next time
01:13 PM gloops: unfinished project .99p https://www.ebay.co.uk/itm/3d-printer-router-project-stepper-motor-arduino/162897773249?
01:16 PM miss0r: fragalot: I'm uploading a complete gallery of the build - it is done now. hang on i'll give you the link - You can just skip to the end and see the complete unit
01:19 PM fragalot: miss0r:^k
01:20 PM miss0r: There we go: https://imgur.com/a/XxU1N
01:22 PM miss0r: I'm sad that it ended up having that box section on the side. But overall I am pleased
01:22 PM fragalot: that servo mount is so overbuilt, I love it
01:22 PM miss0r: Whats not to love ;]
01:23 PM fragalot: I finally got around to checking the total indicated runout of my spindle i'm going to use
01:23 PM miss0r: Next up, the control box needs an overhaul
01:23 PM miss0r: How bad/good is it?
01:23 PM fragalot: 0.012mm
01:24 PM miss0r: For what exactly?
01:24 PM DaViruz: miss0r: how'd you align the servo with the shaft?
01:24 PM fragalot: miss0r: indicator on a 6mm gauge pin in a 6mm ER25 collet
01:25 PM miss0r: DaViruz: I mounted it in center over the shaft? I'm not sure I understand your question
01:25 PM miss0r: fragalot: How long is that gauge pin?
01:25 PM fragalot: miss0r: 50mm, with 25mm sticking out
01:25 PM miss0r: i.e. is the whole chuck engaged?
01:25 PM fragalot: yes
01:25 PM miss0r: hmm.. sucks
01:25 PM fragalot: yup
01:26 PM miss0r: I would re-grind the collect holder
01:26 PM fragalot: yup, but for that I need the machine up first
01:26 PM miss0r: how so?
01:26 PM fragalot: because I have nothing accurate enough
01:26 PM fragalot: unless if I do it on the lathe
01:26 PM miss0r: that was what I was thinking
01:27 PM fragalot: but I figure it's going to be easier if I just do it in place when the cnc is built
01:27 PM miss0r: That is an option. but if you can clamp and indicate the spindle good enough in the lathe, I would recommend that.
01:27 PM miss0r: Less to go wrong
01:29 PM fragalot: about the same, I think?
01:29 PM fragalot: I don't have an angle plate large en... oh actually I do
01:30 PM DaViruz: miss0r: mostly i'm suggesting you may create som misalignement forces and lose some torque with that coupling if it's not accurately aligned. i recall you being worried about the servo having enough torque
01:30 PM miss0r: You could just do the math and use an indicator on the lathe, that is what I do
01:30 PM fragalot: miss0r: yeah, in both cases i'd do it the same way, just mounted differently
01:31 PM miss0r: DaViruz: Indeed. What misalignment I might have caused, should be OK, with the rubber mount the servo sits in
01:31 PM DaViruz: oh.
01:31 PM fragalot: miss0r: you would have gotten bonus points if you made it a torx coupling
01:31 PM miss0r: hehehe. Yeah, i didn't feel like it
01:35 PM miss0r: I'm out for tonight. See you guys around
01:57 PM jelly-home is now known as jelly
01:57 PM MrHindsight: anyone here use the Path/CAM feature in Freecad?
01:58 PM Simonious: no, is it awesome?
01:58 PM MrHindsight: dunno
01:58 PM MrHindsight: why I'm asking
01:58 PM MrHindsight: I hear that "it works", but not how well
01:59 PM acassis: MrHindsight: https://www.youtube.com/watch?v=k1ezXIaOw60
01:59 PM acassis: MrHindsight: I didn't test it yet, but it is improving fast!
02:00 PM MrHindsight: just got the robot sim in Freecad to move
02:02 PM gloops: well done
02:03 PM acassis: MrHindsight: there are other nice demo here: https://www.youtube.com/watch?v=5UbuWERtpuE
02:04 PM MrHindsight: acassis: I want to model this in Freecad https://www.youtube.com/watch?v=ik_v17EwucU
02:04 PM MrHindsight: and then use the Path feature to record the motion, similar to Teach mode on a robot
02:05 PM MrHindsight: then use the G-code with LCNC
02:05 PM fragalot: I absolutely love software demo's in languages that aren't english
02:06 PM MrHindsight: looks like Freecad is a good open source starting point
02:06 PM acassis: fragalot: I prefer when it is Chinese or Japanese ;-)
02:07 PM fragalot: acassis: with an english title
02:07 PM MrHindsight: I wonder how many LCNC users there are in China or India
02:07 PM acassis: MrHindsight: yes and since it supports scripting in Python you can do some interaction as well
02:07 PM fragalot: :P
02:08 PM gloops: freecad should unite with linuxcnc
02:08 PM MrHindsight: acassis: the point is to avoid having the non-programmer user of the robot HAVE to write G-code
02:09 PM acassis: MrHindsight: ok, understood the idea
02:09 PM MrHindsight: they can get the hang of it over time, but they can pre-flight the motion in Freecad, then run it on the bot
02:09 PM MrHindsight: now if only Nuttx had 3d accel support for AMD
02:10 PM acassis: MrHindsight: Bali I think you mean Linux, not NuttX right ? rs
02:11 PM MrHindsight: acassis: was actually thinking of 3d accel with Nuttx
02:11 PM MrHindsight: 3d works great with Linux on x86
02:13 PM MrHindsight: Vivante GPU's with ARM on Nuttx would be nice
02:18 PM acassis: MrHindsight: I'm trying to replace by router spindle with this one: https://www.amazon.com/MYSWEETY-Cooled-Spindle-Collet-Converter/dp/B06VY6PM6N/
02:18 PM acassis: MrHindsight: but this is a little bit expensive :-/
02:21 PM MrHindsight: I see it for $370 without the collets
02:22 PM MrHindsight: acassis: what are the import duties/taxes for that?
02:23 PM acassis: MrHindsight: do have the link? is it 110V as well?
02:23 PM MrHindsight: when we ship resin there we hear it's like %50
02:23 PM acassis: this is my issue
02:23 PM acassis: MrHindsight: I will ship it to USA
02:23 PM MrHindsight: https://www.amazon.com/dp/B078J5CXP3
02:24 PM gloops: just the spindle no vfd?
02:24 PM MrHindsight: spindle, vfd, mount and pump
02:24 PM acassis: MrHindsight: this model is 220V
02:25 PM MrHindsight: ah you need 110V?
02:26 PM acassis: yes
02:27 PM fragalot: can you even run a 2.2kw spindle on 110V? (serious question, I thought most 110V installs only went to 15A?
02:27 PM SpeedEvil: 'yes'
02:27 PM SpeedEvil: in that with the proper driver, it will get both better torque, and higher RPM than a lower wattage spindle.
02:27 PM MrHindsight: fragalot: 20A is common
02:27 PM acassis: fragalot: good question!
02:28 PM SpeedEvil: But, it will of course cap out on total wattage
02:28 PM fragalot: MrHindsight: Right. Seems near the limit though :P
02:28 PM MrHindsight: yes
02:28 PM MrHindsight: but it's Chinese watts
02:28 PM jym: There are 20A 11V outlets/circuits too, just not "typical"
02:28 PM fragalot: haha
02:28 PM jym: 110V*
02:28 PM MrHindsight: so somewhere between 1000 and 2200 W
02:28 PM jym: MrHindsight: Oh chinese watts, then read them as reverse watts
02:29 PM MrHindsight: in everywhere else Watts
02:29 PM gloops: https://www.ebay.co.uk/itm/1-5KW-ER11-Spindle-Motor-Water-cooled-AC110V-1-5KW-VFD-Bracket-Pump-Kit/201580743512?
02:29 PM gloops: ok if you happen to be going to china
02:30 PM jym: gloops: Like France?
02:31 PM fragalot: is that a cast aluminium spindle holder?
02:31 PM fragalot: I wonder if they bother boring it out
02:32 PM gloops: collet size not practical reallt, er11
02:33 PM gloops: cant you just plug a 220 into a 110 box?
02:33 PM fragalot: depends on the VFD
02:33 PM gloops: jym there are lots of useful things in france if you happen to be going there
02:33 PM gloops: well i dunno actually
02:34 PM jym: gloops: frogs legs? snails?

02:35 PM Crom_: installed Mint on it
02:36 PM Crom_: downloading what ever current Linuxcnc iso is available
02:37 PM gloops: you run linuxcnc on mint ok Crom?
02:37 PM gloops: i made a right mess of it when i tried installing on mint
02:38 PM Crom_: just installed, cuz it's what was handy...
02:42 PM Crom_: downloading linuxcnc-2.7-wheezy.iso
02:44 PM gloops: yeah thats the standard download at the moment i think
03:05 PM XXCoder: whew
03:05 PM XXCoder: painted a bunch
03:05 PM XXCoder: gonna do second coat soonish
03:07 PM gloops: walls or woodwork?
03:07 PM XXCoder: concerete walls
03:07 PM XXCoder: its a sealant
03:07 PM XXCoder: so we can put isulation on top of it
03:08 PM XXCoder: today we plan to do second coat then isulation, done for weekeb
03:08 PM gloops: ahh, thats not so bad then
03:08 PM XXCoder: wahts sad is we covered up painting thats older than me'
03:08 PM XXCoder: I guess its in least 60 years old
03:08 PM gloops: yeah something a bit funny about doing that
03:08 PM jym: I'd have said 120years
03:08 PM XXCoder: but its cracking a little and we need to seal concerete
03:09 PM XXCoder: BUTTTT
03:09 PM XXCoder: we preserved it kind of, digitally.
03:10 PM gloops: soon be ready to start making machines then XXCoder heh
03:19 PM Crom_: eta went from hour to 2 minutes changing to eth0 hard wired
03:22 PM Crom_: need to change this IBM to a 2TB drive... 150GB is filling up
03:23 PM gloops: you running your cnc from this Crom?

03:32 PM XXCoder: shop will be new building not here
03:36 PM gloops: ahh right XXCoder few big rooms to go at there then, i used to like painting actually i think ive grown out of it with age
03:41 PM MrHindsight: XQuartz? does it work with LCNC?
03:41 PM XXCoder: heh so fun, painting :P
03:41 PM MrHindsight: say I have my $34,000 Mac airbook pro + kickkass edition

03:54 PM XXCoder: pocketnc fancy
04:07 PM gloops: just ready a page about open source engineering, for the third world, like concrete lathes and drills made out of old bits and bobs
04:07 PM gloops: all these plans, thing is, if they havent got a drill, are they likely to be online to see these ideas
04:07 PM gloops: reading
04:07 PM XXCoder: gloops: lathe is over 3500 years old.
04:08 PM gloops: well yeah, these are metal lathes and drills
04:08 PM XXCoder: mill is a egg compared to that lol

04:11 PM XXCoder: I wonder how long from hand tools only to precision machines
04:12 PM MrHindsight: https://www.youtube.com/watch?v=eurX6r83X3w dis is the video!
04:12 PM MrHindsight: all yah needs is an old car and some hands
04:13 PM XXCoder: car isn't hand tool ;)
04:14 PM MrHindsight: no no noes
04:14 PM MrHindsight: well it is without gas
04:15 PM gloops: 'easy to build' haha
04:16 PM MrHindsight: easy is always subjective
04:18 PM MrHindsight: I'd like to see a version where the first steps are "find a crop you can farm and sell to the 1st world, like poppies"
04:18 PM gloops: well, everything is made from pretty standard components these days, you can find them all on old cars, washing machines, computers, but mainly old bicycles
04:18 PM MrHindsight: sell powder produced by crops, use money to buy CNC
04:20 PM gloops: why do any of that? was a pretty idyllic life before they wanted industry
04:20 PM MrHindsight: cow died so the village disbanded
04:21 PM MrHindsight: I use lots of standard automation parts myself, servos, linear and rotary positioners, ball screws etc
04:23 PM gloops: improvise
04:24 PM gregcnc: Capt did we see this one yet https://www.protomax.com/ pint ,well 10 gallon size waterjet?
04:28 PM MrHindsight: tiny
04:30 PM gloops: uk is leading the way with this
04:31 PM gloops: britain is losing its old flat cap and big hammer persona rapidly https://www.youtube.com/watch?v=XfGkLsUm92Q
04:39 PM JT-Shop: cobbled together a mobile paint rack from some crap I've been hording lol http://gnipsel.com/images/equipment/paint-rack/paint-rack-01.jpg
04:41 PM jym: JT-Shop: That works =)
04:44 PM JT-Shop: yep, I built some weigh pack lines years ago and kept the conveyor parts I didn't use... finally came in handy
04:44 PM JT-Shop: well actually I've built a storage rack from some of that stuff
04:49 PM SpeedEvil: gloops https://www.youtube.com/watch?v=6W_7uIapoHc
04:50 PM SpeedEvil: On the topic of axis and cement.
04:54 PM Crom: OK installing linuxcnc2.7 to Dell Wyse#1
04:57 PM JT-Shop: I think my dirt is done cooking... I'll take it off the stove in the morning
04:57 PM MarcelineVQ: yummu
04:57 PM MarcelineVQ: I ​had toast myself, but each to their own
04:58 PM JT-Shop: well it's for the chickens dust bath
04:58 PM JT-Shop: I dry it out then mix with some ash from the stove and they love it
05:20 PM Skullworks: Any word as to when v2.8 will be officially released?
05:21 PM JT-Shop: might be better to ask that on #linuxcnc-devel
05:22 PM Skullworks: Oh - I figured if it were anywhere close the rumor mill would know.
05:22 PM jym: I have a 135A alternator, and want to use an inverter drawing 1200W, what should I look out for?
05:23 PM * JT-Shop goes to lock the chickens up for the night
05:23 PM jym: JT-Shop: What happened to auto-chicken-door?
05:23 PM Skullworks: jym just be sure the DC feed is using the proper guage wire and you should be good to go.
05:46 PM jym: Skullworks: I'm more consernced with damaging automotive electrical than anything else
05:48 PM Skullworks: Your system will be @ 13.8-14.1VDC
05:50 PM Skullworks: so your lookin at 87A peak
05:52 PM Skullworks: prolly want to be running about 2200-3500 rpm to keep the alt cool
05:54 PM Skullworks: btw thats crank rpm - Alt will be running faster
05:55 PM malcom2073: +1 for raise RPM, figure out what RPM the alt is capable of outputting that current at. That being said, you're not likely to be drawing continuous 1200W from the inverter
05:56 PM malcom2073: Wire and fuse it for the max current, but you may be alright at idle
05:58 PM Skullworks: I used to work at a little corp called IHeartMedia.
05:59 PM malcom2073: We used to have 2000W puresine inverters in our work trucks, and we just ran them with 50A fuses and 8AWG wire, since we never actually loaded them down
05:59 PM jym: malcom2073: Well for at least 5 minutes... microwave =)
06:00 PM Skullworks: I wired up many of the promotions vehicles with 4ga. wire to inverters and/or direct wiring into Fender amps.
06:00 PM Skullworks: Parades - state fair etc.
06:00 PM jym: What *I* don't get is why I have a stock 1235A alternator, I can't see the SUV drawing THAT much power normally
06:01 PM jym: 135A
06:01 PM malcom2073: Got a lot of 12V power ports in it?
06:01 PM jym: malcom2073: Nope, just two
06:02 PM jym: and I don't have an amp meter capable of that high to read what it draws
06:02 PM malcom2073: iirc, my car has a 120A factory
06:03 PM Skullworks: Air conditioning fan plus mag clutch inrush + High beams + fuel injection pump + stereo + back seat DVR + cell chargers + safety overhead
06:03 PM malcom2073: Our F350's had like, 4-5 electric cooling fans, all of them huge
06:04 PM jym: malcom2073: under the hood?
06:04 PM malcom2073: jym: Yeah, the transmission had its own too
06:04 PM malcom2073: transmission cooler that is
06:04 PM sync: jym: that is "only" 1.6kW
06:05 PM jym: sync: what is?
06:05 PM sync: your alternator
06:05 PM sync: 250A alternators are not unheard of
06:05 PM malcom2073: I have a 175A 24V alternator sitting on my shelf heh
06:05 PM malcom2073: Have yet to figure out wtf I'm going to use it for
06:05 PM jym: sync: Sure, but companys like to "cheap out", I was thinking they would try to get away with 60 or 80 Amp
06:06 PM sync: they are cheaping out
06:06 PM sync: by ordering millions of the alternator they need for the loaded model
06:06 PM sync: also 60-80A worked in the early 90s
06:06 PM sync: but not now
06:06 PM sync: 10A is only 120W
06:06 PM jym: So, what does a typical 2001 SUV draw as far as amperage? I wouldn't want to overload the alternator
06:07 PM Skullworks: Warranty repair work always costs many times the cost of the failed part - so be sure OEM parts will outlast warranty period.
06:07 PM sync: you'll need to measure
06:07 PM malcom2073: Also it varies based on RPM, higher RPM higher power usage
06:10 PM sync: but if you are actually drawing 1.2kW you are most likely overloading it although it probably would not be an issue as the battery will just not charge then
06:12 PM jym: sync: I'm kinda ok with the battery not charging, just don't want to fry the alternator/VR
06:16 PM jym: Has anyone used one of these style shunts? https://www.ebay.com/itm/Hot-Voltmeter-Ammeter-DC-100V-50A-100A-LED-Dual-Digital-Volt-Amp-Meter-Gauge-US/292202998161
06:16 PM malcom2073: Yep
06:17 PM jym: malcom2073: any good?
06:17 PM malcom2073: I'd question the quality of it, being only $5 from china, but hey.. it'll probably be within 10-15%?
06:18 PM malcom2073: Our super accurate ones use shunts, since you can really finely calibrate them (the more accurately you can measure the resistance, the more accurately you can measure the voltage)
06:18 PM malcom2073: for that price though, buy one, put a known load on it, and see what it does
06:18 PM malcom2073: like, a 1000W heat gun on your 1200W inverter :P
06:19 PM malcom2073: Chinese new year though, that seller is afk
06:20 PM Crom_: that's why I ran Mint... it sees
06:22 PM malcom2073: huh?
06:22 PM jym: malcom2073: 500A http://www.rc-electronics-usa.com/buy-current-shunt.html
06:22 PM malcom2073: I'd trust that a bit more, if only for the price
06:22 PM malcom2073: You need a meter matched to that resistance though
06:23 PM malcom2073: If you want a nice meter like the one on the ebay link
06:23 PM Crom_: all my wifi cards
06:23 PM jym: malcom2073: Does clamp on DC Amps... https://www.amazon.com/Signstek-UT210E-Handheld-Resistance-Capacitance/dp/B00V9XAT4Y/
06:24 PM malcom2073: jym: If they're made for it, yes
06:24 PM malcom2073: I have one of thoes, they're great for quick measurements
06:24 PM malcom2073: Be aware: Only clamp one wire. If you clamp both + and -, it'll read 0
06:24 PM jym: malcom2073: That LITERAL model# you have?
06:24 PM malcom2073: jym: No
06:24 PM malcom2073: jym: An AC/DC Digital clamp meter
06:25 PM malcom2073: got a cheapie from home depot
06:25 PM jym: malcom2073: and it does DC amps?
06:25 PM jym: 100A
06:25 PM jym: ?
06:25 PM sync: jym: you need more than 100A tho
06:25 PM sync: like the ut210d
06:25 PM malcom2073: jym: yeah
06:26 PM malcom2073: Yeah you want more than 100A, since you may do up to 110-120A
06:27 PM jym: malcom2073: Not worried about the rating of 100A, just need to know the base draw of the vehicle,
06:27 PM malcom2073: Ah yeah that sort of meter should do fine for that
06:27 PM malcom2073: clamp it around your positive terminal
06:28 PM malcom2073: erm wait no
06:28 PM jym: malcom2073: what model# did you get from home depot?
06:28 PM malcom2073: Around your alternator line after idlign for a while to bring the battery up to voltage
06:28 PM malcom2073: jym: I have no clue, I can look tomorrow morning
06:28 PM jym: malcom2073: appreciate it, thanks =)
06:30 PM malcom2073: Though, it was like, 5 years ago, so no garuntee they still carry that one :P
06:30 PM jym: malcom2073: 600A ?! https://www.homedepot.com/p/Klein-Tools-600-Amp-AC-DC-True-RMS-Auto-Ranging-Digital-Clamp-Meter-CL800/206517428
06:31 PM malcom2073: Haha, I'm pretty sure I didn't pay more than like $30
06:54 PM Crom_: damn IWLWIFI intel card
07:22 PM SpeedEvil is now known as Guest72866
07:32 PM Skullworks: T minus 30
07:41 PM Skullworks: T minus 20
07:41 PM jesseg: What're you counting down Skullworks ? Is there a live video feed? :P
07:43 PM Skullworks: I have been working helpdesk all day - counting off the remaining minutes of a shift which received ZERO calls
07:43 PM Skullworks: but the endless misic loop is driving me daffy
07:45 PM Crom: debian install seesnthe card, gets IP# after install it doesn';t see didley.. Bo or otherwise
07:45 PM Crom: Skullworks: hehe,saivor those days!
07:46 PM Crom: speaker even in ceiling should have volume control
07:46 PM Skullworks: Sorry - nothing as exciting as launching a used car into orbit as an advertising write off.
07:49 PM Skullworks: Oh - I know - there will be a new software release being mailed on USB drives about the 19th, once staff start trying to migrate it will be a full mad house here.
07:50 PM jym: Skullworks: what do you support?
07:51 PM Skullworks: Turbo Tax Agents
07:51 PM jym: poor bastard
07:52 PM Skullworks: and all the VPN and app packages related
07:52 PM Skullworks: the new release is a whole new disk image.
07:59 PM Skullworks: I need to find someone with with Alexa - and Ask Hey should I buy a 3rd Hurco CNC mill? - You know, kind of a digital magic 8 ball.
08:00 PM Skullworks: But being Alexa - Amazon prolly has one and will want to sell it to me.
08:07 PM * Skullworks has had enough of this chair.
08:07 PM Skullworks: later folks
08:10 PM gregcnc: is the nuker rated 1200W or actual draw is 1200W?
08:15 PM Tom_L: ever had an issue with setting your tool heights up in the tool table and setting the z fixture offset with that tool but starting the program with another tool?
08:16 PM Tom_L: i set them with T1 and start with T5
08:16 PM gregcnc: what goes wrong?
08:16 PM Tom_L: when T1 gets called it's going to the start of the leadin move for T5 instead of starting at X0 Y0 as programmed
08:16 PM Tom_L: Z is ok, it's X and Y that are getting messed up
08:17 PM Tom_L: the model in my cad cam is fine
08:17 PM Tom_L: but i can see what it's doing
08:17 PM Tom_L: one sec
08:18 PM gregcnc: what does the gcode actually say?
08:19 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/toolpaths.jpg
08:20 PM Tom_L: it goes to the lower hole first but misses the top hole by the distance between the first tool leadin and the actual hole location
08:20 PM Tom_L: i've run the program before but changed the tool order a bit
08:24 PM gregcnc: are work offsets being called correctly?
08:24 PM Tom_L: i call them once at the beginning i'm pretty sure
08:24 PM ASRock_pc: http://paste.debian.net/1009827/
08:24 PM Tom_L: there's the first few lines of both tools
08:25 PM Tom_L: i've never had an issue with work offsets
08:25 PM Tom_L: G54 is selected
08:25 PM Tom_L: by default
08:25 PM MrHindsight: gregcnc: was thinking of money generating applications for that mini waterjet
08:25 PM Tom_L: and i checked it before i ran it
08:25 PM gregcnc: come up with anything? i didn't see a price tag
08:25 PM MrHindsight: $20k
08:26 PM gregcnc: yeah made by a real waterjet co.
08:26 PM MrHindsight: $19,950, includes shipping and everything you need to cut your first parts.
08:26 PM gregcnc: tom_l so it doesn't move to the programmed coordinates?
08:26 PM Tom_L: i just don't like setting tool offsets and work offsets with a short tool
08:26 PM MrHindsight: maybe metal supermarkets or similar, but the work area is so small
08:26 PM Tom_L: no it goes to the first start of move spot you see in the pic
08:27 PM Tom_L: but it does it on the 2nd hole
08:27 PM gregcnc: i can't correlate the code to the part as far as scale
08:27 PM BitEvil is now known as SpeedEvil
08:28 PM MrHindsight: $400/mo + consumables and electricity
08:28 PM gregcnc: lease?
08:28 PM MrHindsight: financed over 60 mo
08:28 PM Tom_L: i just don't feel it's a good idea to set the work offset with a short tool
08:29 PM MrHindsight: " largest in-house team in the world."
08:29 PM gregcnc: using a different tool shouldn't matter
08:29 PM MrHindsight: hmm maybe a few guys 400lbs each?
08:29 PM gregcnc: hehe
08:31 PM gregcnc: and ceratinly if only using Z offset X,Y shouldn't be affected
08:35 PM Tom_L: i know
08:35 PM Tom_L: it's rather odd
08:35 PM gregcnc: is the gcode for the proper position?
08:35 PM Tom_L: what do you mean?
08:36 PM gregcnc: I don't see X0.Y0. in the code
08:36 PM Tom_L: i set that when i set the tools
08:36 PM Tom_L: with G54
08:36 PM Tom_L: the T5 ran fine
08:37 PM Tom_L: and i've run this post with linuxcnc for quite a while now
08:37 PM Tom_L: anyway, back out there..
08:38 PM gregcnc: thinking this is CAM issue
08:40 PM gregcnc: no reason for LinuxCNC to drill one hole correctly and miss the location of the next
08:40 PM Tom_shop: i agree
08:40 PM Tom_shop: however the mill was acting a bit odd this morning when it was cold in the shop
08:41 PM gregcnc: if the coordiantes were correct but position is wrong could be machine related
08:42 PM Tom_shop: i just ran the drill by itself and it's in the wrong place too
08:42 PM Tom_shop: i'll figure it out
08:42 PM Tom_shop: i'll probably set the tools with the first tool called and see if that helps
08:44 PM Tom_shop: ok i just told it to go to X0 Y0 and it went to the start of the first tool profile instead of G54 X0 Y0
08:44 PM Tom_shop: G54 is active
08:45 PM Tom_shop: and you can see a shift in the graphic in axis preview
08:45 PM Tom_shop: 2 parts displayed offset by that distance
08:46 PM Tom_shop: luckily i stored the value in another unused offset too so i can get it's exact location back
08:47 PM gregcnc: when calling G54 you should not have any coordinates after, otherwise you shift the coordinate system
08:47 PM Tom_shop: it's off in Y by .7861
08:47 PM Tom_shop: err i mean X
08:48 PM gregcnc: hmm i'm not sure that it shifts it
08:48 PM gregcnc: but I never use work offsets that way
08:48 PM Tom_shop: i've always done it that way
08:48 PM Tom_shop: i'll add G54 to the start of each tool and see what happens
08:49 PM gregcnc: I only call it once at the top
08:49 PM Tom_shop: but the offset got changed in lcnc without operator intervention
08:51 PM gregcnc: no g92 or g10 anytime?
08:51 PM Tom_shop: no
08:52 PM Tom_shop: not even in my post
08:52 PM gregcnc: I have run into a case where if I estop a program with esc it cancels offsets
08:52 PM gregcnc: it will do it consistently but I can't remember the steps to make it happen
08:53 PM Tom_shop: well, i was smart enough to save them in an unused offset so i'm ok i think
08:53 PM gregcnc: somebody else commented on it atleast once here
08:53 PM gregcnc: only cost me a few tools
08:53 PM Tom_shop: i'm running it dry until i'm convinced it's ok
08:54 PM Tom_shop: ok i ran the same drill file with G54 at the top and it ran ok that time
08:54 PM Tom_shop: very odd
08:55 PM Tom_shop: but i'll be adding that to my post for sure
08:55 PM Tom_shop: i pulled the drill code out of the main file to run separately
08:55 PM Tom_shop: never ran into that before :)
10:08 PM XXCoder: whooo
10:08 PM XXCoder: downstairs partially isulated no
10:08 PM XXCoder: now
10:08 PM XXCoder: made pretty good difference
10:12 PM Tom_L: ok something very strange is going on with the offset values
10:12 PM XXCoder: yeah? whats happening'
10:12 PM Tom_L: read the log
10:13 PM XXCoder: wondering if its cold affecting stuff. how far off was one hole off by
10:14 PM Tom_L: <Tom_shop> it's off in Y by .7861
10:14 PM XXCoder: hurcos require 10 minute session of constantly moving X Y and spinning spindle 1000 rpm to warm up
10:14 PM XXCoder: a61 just need spindle to be warm if left alone 5 hours
10:14 PM XXCoder: oh missed that
10:15 PM XXCoder: that is way more than cold effect
10:15 PM Tom_L: but i reset it and ran it and on the following tool it was off again
10:15 PM XXCoder: t and h matching?
10:15 PM Tom_L: pretty sure
10:16 PM XXCoder: pretty low probility thing yea
10:16 PM Tom_L: the issue started when i set the offsets with the longest tool, not the first one called in the program
10:16 PM XXCoder: I doubt its diameter thing
10:17 PM Tom_L: maybe a coincidence i dunno
10:19 PM XXCoder: change of coord between?
10:19 PM XXCoder: suddenly its g55
10:19 PM Tom_L: no i'm only using G54
10:19 PM XXCoder: yeah was wondering if it was cam error
10:20 PM Tom_L: i've used the same cam for a long time and the cad cam program for probably 25 yrs
10:20 PM XXCoder: no, wasnt saying you personally screwed up :)
10:20 PM Tom_L: i know
10:21 PM XXCoder: hm
10:21 PM XXCoder: not really have any other idea
10:21 PM Tom_L: i'll figure it out another day
10:22 PM XXCoder: hope so. please tell us :D
10:22 PM XXCoder: because it'd be one less lesson :)
10:22 PM XXCoder: *we'd have to personally experence
10:24 PM XXCoder: btw what cad and cam you use?
10:27 PM XXCoder: I tried few of cam and best I tried so far was estlcam, followed by fusion360 then freecad
10:31 PM Tom_L: i've got smartcam which was the leading cad cam when i purchased it years ago
10:31 PM Tom_L: comparable to mastercam
10:33 PM XXCoder: samsung smartcam. I guess it went away while ao
10:33 PM XXCoder: found website
10:36 PM XXCoder: looks like I can't afford it lol
10:36 PM XXCoder: no price anywhere
10:38 PM XXCoder: estlcam is trying to be cnc controller
10:38 PM XXCoder: it dont look great as controller
10:39 PM XXCoder: its pretty darn good on 2d style or with some work 2.5d.
10:39 PM XXCoder: it also has 3d but it takes form of 3d model and cutting it on one side then another
10:40 PM XXCoder: watching smartcam run. pretty cool
10:44 PM Tom_L: it's been sold a few times
11:03 PM XXCoder: interesting
11:04 PM XXCoder: sorry had to talk for a bit lol
11:04 PM XXCoder: resuming that video
11:04 PM XXCoder: https://www.youtube.com/watch?v=bMlcZT4lVpQ
11:05 PM XXCoder: its pretty old, and already better than all linux possible cams
11:13 PM Tom_L: i've got all the post that was available for it
11:14 PM Tom_L: and they can be modified pretty easy
11:15 PM XXCoder: im trying to figure what to do about my job
11:15 PM XXCoder: career
11:16 PM XXCoder: my back pain doubled ever since I had flu, and stayed there since
11:16 PM XXCoder: I can barely bend to pick stuff up
