12:11 AM fragalot: Hi
12:14 AM Wolf__: morning
12:36 AM sealive: morning from stormy germany
01:09 AM gr33n7007h is now known as Guest58860
01:10 AM sealive: im off 2 garden
02:11 AM Deejay: moin
02:17 AM Loetmichel: *gnhihi* had the valve hydraulic lifters clatter for 5 seconds after a cold start on my BMW 318i convertible for a few days. Now i know why: no oil!... just put in 2 liters, NOW the dipstick says "half full" :-)
04:57 AM jthornton: morning
04:58 AM XXCoder: yo
04:58 AM XXCoder: man
04:58 AM XXCoder: one of workers at work was fired
04:58 AM jthornton: hmm there is a mouse in the chicken run
04:58 AM XXCoder: I thought he was doing ok, but apparently he made mistakes again and again and hes been machinist for 30 years
04:59 AM XXCoder: and he inflated parts count by more than twice
04:59 AM XXCoder: too bad really. I know im not amazing cnc machinist but im in least honest and always learning
05:02 AM jthornton: my buddy ran a turrent lathe at McDonnell Douglas from the time he got back from viet nam, he almost got fired once for not waiting for and inspection on his setup
05:04 AM jthornton: I need to put out some mice traps... damn varmints are bad this year
05:05 AM XXCoder: jthornton: lemme find that video
05:06 AM XXCoder: and yeah risky to run parts without q
05:06 AM XXCoder: qa
05:06 AM XXCoder: https://www.youtube.com/watch?v=FPSlzg-oqoo
05:08 AM sync: well not really, QA will just find the bad parts later
05:08 AM XXCoder: honestly it seems simple enough. there is 3d printed versions thats even simpler
05:08 AM XXCoder: you dont even need to tie string with printed version
09:00 AM jesseg: Morning folks!
09:06 AM JT-Shop: morning
09:18 AM * JT-Shop can't remember how to build a deb :(
09:40 AM sealive: hi all
09:41 AM sealive: someone got the new wiki edit pass
09:41 AM sealive: i woudt like to change the link fro airfoil script
09:44 AM sealive: JT-Shop, ?
09:46 AM sealive: cradek, online ?
09:47 AM sealive: Loetmichel, did you got water last night
09:47 AM sealive: here it is dry not a single drop
09:58 AM sealive: off till later
10:31 AM JT-Shop: yo
10:32 AM skunkworks: MMmmm first coffee of the day
10:32 AM gregcnc: at 10:30?
10:36 AM skunkworks: yes
10:39 AM jepler: It's been about a week since I silenced unregistered users. I had originally stated I'd keep the ban for at least a week. How's anybody feel about removing the channel mode?
10:43 AM tjtr33: is there a way to 'slice' a gcode file?
10:43 AM tjtr33: I want to cut 3D_chips.ngc but all my cutters have very short side cutting ability,
10:43 AM tjtr33: so I'd like to cut it in vertically layered slices.
10:44 AM gregcnc: this is normally handled by CAM which generates the code
10:44 AM skunkworks: cheap and dirty would be just to run 3d chips over and over by lowering the z each time
10:45 AM tjtr33: yes, 3D_chips was made by very very original emc guys and the model is not available.
10:45 AM gregcnc: that will work
10:46 AM tjtr33: thanks skunk, no suggestions for turning gcode to stl?
10:47 AM jthornton: I still see spam in other channels that don't have ops
10:47 AM jepler: OK, based on feedback here and in #linuxcnc-devel I'll leave the ban in place for another week.
10:48 AM skunkworks: there was a newer model.. alex joni maybe had it?
10:48 AM tjtr33: thx , off to romania ( i think )
10:49 AM skunkworks: Thanks jepler!
11:04 AM tjtr33: well i found Rab's site and a picture of the original BDI model, but no 3D model :-(
11:04 AM tjtr33: It was nice to see the BDI cd animation though, like a zoetrope.
11:05 AM tjtr33: ttul8r
11:08 AM Loetmichel: skunkworks: its 18:06 here now... and i had a hectic enough day that the coffee at the company had reduced to a black tar lik substance on the bottom of the pot... didnt get time to drink one at all :-(
11:09 AM Loetmichel: jepler: looks great how it is now for me...
11:27 AM fragalot: Hi
11:45 AM Lcvette[m]: Hey all
11:48 AM Lcvette[m]: Is it slow or am I invisible again?
11:50 AM jthornton: no your not invisible
11:51 AM Lcvette[m]: Hey.. I'm alive!
11:51 AM Lcvette[m]: Hey JT
11:52 AM Lcvette[m]: Hazzy showed me the UI for the 7i96
11:52 AM Lcvette[m]: Pretty sick
11:52 AM Lcvette[m]: Slick*
11:52 AM jthornton: thanks
11:53 AM jthornton: still lots of work to do but it will make a working configuration now
11:55 AM Lcvette[m]: Nice!!! It looked awesome, what are you using it for?
11:55 AM Lcvette[m]: Anything in particular or just in general as a confirmation builder?
11:55 AM Lcvette[m]: Config*
11:56 AM jthornton: just trying to make a simple configuration builder
11:57 AM Lcvette[m]: Awesome!
11:57 AM jthornton: and learn about pyqt5
11:58 AM Lcvette[m]: Same here!
11:58 AM Lcvette[m]: And LinuxCNC
11:58 AM Lcvette[m]: Crash course. Like drinking from a fire hose
11:59 AM Lcvette[m]: Hahahaha
12:00 PM Lcvette[m]: Right now I'm trying to work out a method to be able to have probe calibration offsets for x+, x-, y+, y-
12:00 PM jthornton: do you have the probe routines?
12:01 PM Lcvette[m]: To compensate for irregular triggering in the tripod probe designs
12:01 PM Lcvette[m]: I have one we built as a rough working test platform
12:01 PM jthornton: ah I see
12:02 PM jthornton: lunch minute is over so back to doing some work
12:02 PM Lcvette[m]: It's for a corner
12:02 PM Lcvette[m]: Don't work too hard!
01:13 PM fragalot: evenin'
01:14 PM miss0r: 'ello
01:14 PM fragalot: turns out that .02mm in Z along Y that I had really is just due to the casting flexing
01:14 PM miss0r: Yeah... You nailed it
01:14 PM fragalot: goes away when I loosen the bolts to the stand
01:14 PM miss0r: :D
01:15 PM miss0r: You could probally shim that
01:15 PM fragalot: 'ndeed
01:15 PM fragalot: all that's left really is to lift that far too heavy head back onto the machine
01:15 PM fragalot: watch it flex even more
01:15 PM fragalot: and then machine new gibs myself
01:15 PM miss0r: Sweet
01:16 PM miss0r: I got my 8x40x150 and my 12x50x150 endmills in the mail today :D They are looking GOOD
01:17 PM fragalot: 12x50 ?
01:17 PM fragalot: only 50mm usable surface?
01:17 PM fragalot: pah
01:17 PM miss0r: meh...
01:18 PM miss0r: I don't want 120mm helix! it would be uncontrollable !
01:18 PM miss0r: :]
01:18 PM fragalot: :D
01:20 PM miss0r: The only thing shitty about these endmills is that I could not get them with a corner radius.
01:21 PM miss0r: I wonder how long the cutting end will last :D
01:23 PM fragalot: grind it yourself
01:23 PM * fragalot does that all the time on his single lip cutter grinder
01:23 PM miss0r: Sure. But I think I'll run it into the ground first, before starting on that :D
01:24 PM fragalot: just break the very tips on a tool grinder
01:24 PM fragalot: makes a huge difference in terms of life, especially when they're this long
01:24 PM miss0r: then my TIALN coating will go bye bye :P
01:24 PM miss0r: yeah I know.. I just want to see how they perform first
01:26 PM fragalot: you don't have the RPM's to make use of TiALN
01:26 PM fragalot: :P
01:26 PM miss0r: :] But itz soo purty!
02:09 PM JT-Shop: I wonder if hazzy-dev is about
02:20 PM fragalot: syyl_: why are deckel FP4NC's so cheap?
02:39 PM sync: fragalot: because thes are POSes
02:40 PM fragalot: Well then. That explains why there are so many, lol
02:40 PM sync: the issue is that the X way is underlubricated
02:41 PM sync: and galls up
02:41 PM sync: on _all_ of them
02:41 PM fragalot: nice
02:41 PM sync: well
02:41 PM sync: what do you expect, they took a manual machine and cnc'd it
04:11 PM MrHindsight is now known as CaptHindsight
04:11 PM CaptHindsight: anyone every work with pipe inspection robots? https://www.youtube.com/watch?v=lWUtHt5J_Gc
04:11 PM CaptHindsight: turn the sound down
04:11 PM CaptHindsight: https://www.youtube.com/watch?v=6qj8Z4Fj494
05:27 PM roycroft: have any of you folks made a pneumatic drawbar retrofit on a mill with an r8 spindle?
05:27 PM roycroft: i'm trying to figure out what is a reasonable amount of pressure to hold the collet in place
05:28 PM roycroft: i'm seeing folks using cylinders with anywhere from 1500 punds to 4500 pounds of force
05:29 PM roycroft: i'm taking about the kind that just pushes down on the drawbar, which is held with belleville washers
05:29 PM roycroft: not the ratcheting kind that actually unscrew the drawbar
05:30 PM roycroft: also, about 100% of the ones i've seen put on small mills just push down on the spindle to release the collet
05:30 PM roycroft: that seems as though it would put a lot of excessive load on the spindle bearings
05:31 PM SpeedEvil: Well, torque of standard drawbar, thread pull calculator, thread, ...
05:32 PM roycroft: a mechanism that holds the spindle in place while pushing down on the drawbar makes more sense to me, although that would be a lto more complicated
05:32 PM roycroft: yes, i can calculate something sensible
05:32 PM roycroft: i just want a ballpark number for now
05:33 PM roycroft: and i figure linuxcnc'ers probably have better number than youtube warriers
05:35 PM infornography: lurk
05:35 PM roycroft: hmm, if the lower mounting plate for the pneumatic cylinder were attached to the spindle and not to the top of the mill that would eliminate any load on the spindle bearings
05:41 PM SpeedEvil: K - I have no experience as you can probably gather. :)
05:51 PM infornography: is there open source software for drawing and generating G code from the drawing?
05:51 PM Rab: infornography, Inkscape + gcodetools fits that description.
05:52 PM infornography: *makes note
05:56 PM roycroft: pycam is pretty widely used
05:56 PM roycroft: but that requires a drawing
05:56 PM roycroft: it is a gcode converter
05:56 PM roycroft: i think you can make simple sketches directly in pycam
05:57 PM roycroft: freecad is kind of a thing now
05:57 PM roycroft: and a couple of its developers are on this channel
05:57 PM roycroft: they are germans, so they are likely sleeping at the moment
06:00 PM jthornton: roycroft: if you want some anodizing equipment I'll make you a great deal
06:00 PM roycroft: i might be interested
06:00 PM roycroft: depending on how great the deal is :)
06:00 PM Tom_L: closing down that branch of jthornton works inc?
06:01 PM roycroft: i think it's a branch that never opened
06:01 PM jthornton: I'll inventory what I have and pm you
06:01 PM jthornton: aye, never used any of ot
06:01 PM jthornton: it
06:01 PM roycroft: i'm afk much of the time, and have no scroll buffer
06:01 PM roycroft: email me
06:01 PM jthornton: ok
06:01 PM CaptHindsight: unless you are in a hurry big anodizing shops are more cost effective
06:02 PM CaptHindsight: or if they are a long journey by truck
06:02 PM roycroft: not when doing small, one-off prototypes when they have a minimum charge
06:02 PM Tom_L: i think a few here that have tried it may have come to that conclusion
06:02 PM roycroft: i'm only semi-intersted at this point
06:02 PM CaptHindsight: min lot charge around here is $100
06:02 PM jthornton: you have to meet the minimum tho
06:03 PM tumdedum_ is now known as tumdedum
06:03 PM Tom_L: a friend here used to leave his stuff and tell em to toss it in next time they do a batch of whatever color..
06:03 PM roycroft: i was told $80, and that's if they can use whatever dye is in the vat at the time they get around to it
06:03 PM Tom_L: ^^
06:03 PM roycroft: they did not quote me a minimum for my specifying the dye color
06:04 PM roycroft: and i essentially offered to just leave my stuff laying there until they have room for it
06:04 PM roycroft: it's still $80
06:04 PM roycroft: even if it's just one little part
06:04 PM roycroft: a dozen prototypes and a $1k investment in anodizing equipment is paid for
06:05 PM roycroft: however, there are two other major factors:
06:05 PM roycroft: 1. the shop space to store the stuff
06:05 PM roycroft: 2. the cost and relatively short shelf life of consumables
06:05 PM roycroft: oh, and 3. disposal of spent consumables
06:06 PM roycroft: i don't know if it makes sense for me or not at this point
06:06 PM roycroft: a killer deal on the equipment might alter the equation though
06:07 PM roycroft: another option is to make prototypes out of steel, and plan on making the production parts out of aluminium
06:08 PM CaptHindsight: https://ibin.co/34HsTI709hOX.jpg floral t-slot
06:08 PM jthornton: you also could powder coat them if coating thickness is not a factor
06:08 PM Tom_L: depends what testing you plan for the prototypes
06:10 PM roycroft: coating thickness is definitely a factor
06:11 PM jthornton: that eliminates powder coat then
06:11 PM CaptHindsight: is anyone offering powder coatings with images or graphics?
06:11 PM roycroft: yes
06:11 PM roycroft: seems that would be tricky to do, capthindsight
06:11 PM jthornton: my friend's wife does that
06:12 PM Tom_L: how do you mask it?
06:12 PM Tom_L: isn't it a static bond until you bake it?
06:12 PM roycroft: what i *really* should do is find some other company who send stuff out for anodizing on a regular basis and see if i can piggyback on their orders
06:13 PM roycroft: but that would require effort
06:13 PM CaptHindsight: Tom_L: yes, just static until it polymerizes
06:13 PM roycroft: likely more effort than getting the gear and doing it myself
06:14 PM roycroft: the powder could probably be silk-screened on, or some similar process
06:14 PM roycroft: and each color baked separately
06:14 PM CaptHindsight: SLS
06:14 PM CaptHindsight: it works like a laser printer
06:15 PM roycroft: yeah, that could work
06:15 PM CaptHindsight: does
06:18 PM roycroft: has anyone found out what happened with archivist?
06:18 PM Tom_L: yeah, he's busy
06:19 PM roycroft: his website no longer resolves
06:20 PM roycroft: busy happens, and that's better than some of the other possibilities
06:27 PM CaptHindsight: another option is using a an transfer film followed by a powder clear coat
06:29 PM sync: using a resist to pattern anodized stuff is quite nice
06:31 PM CaptHindsight: https://ibin.co/34HsTI709hOX.jpg inkjet in anodize
06:31 PM CaptHindsight: also works for powder coatings if they are relatively flat
06:39 PM sync: yes
09:55 PM zeeshan: hi
09:56 PM Wolf__: yo
09:57 PM Wolf__: whats up zee
09:58 PM zeeshan: CNCing still? :D
09:59 PM Wolf__: not lately, still messing with the x2 build tho
10:00 PM zeeshan: damn irc crashed
10:00 PM zeeshan: its been so long
10:00 PM zeeshan: X3 eh
10:00 PM Wolf__: lol
10:01 PM Wolf__: gonna be using it to learn how to scrape lol
10:01 PM Wolf__: picked up a larger project https://i.imgur.com/Jw1eOEg.jpg
10:04 PM zeeshan: nice!@
10:07 PM Wolf__: little rough, but 1950’s machine so kinda expected
10:13 PM Tom_L: hey zeeshan
10:13 PM zeeshan: whats going on
10:13 PM Tom_L: not alot
10:14 PM Tom_L: milled these tonight http://tom-itx.no-ip.biz:81/~webpage/cnc/Skate_truck/Spacer1.jpg
10:14 PM zeeshan: that looks like a lathe part :D
10:14 PM Tom_L: it does does it?
10:14 PM Tom_L: :)
10:15 PM Tom_L: was easier to get repeatability on the mill
10:15 PM Tom_L: the old lathe's about had it
10:15 PM Tom_L: would be a good cnc lathe part
10:16 PM Tom_L: got yours goin now :=)
10:16 PM zeeshan: mines a chunk of steel
10:16 PM zeeshan: waiting for the scrappers :D
10:16 PM zeeshan: haha
10:16 PM zeeshan: been designing big machines at work
10:16 PM Tom_L: just holdin the floor down ehh
10:16 PM zeeshan: takes all my time
10:16 PM zeeshan: :(
10:17 PM Tom_L: still like the job?
10:18 PM zeeshan: yes
10:19 PM zeeshan: need to get back into cnc sometime soon
10:19 PM zeeshan: :O)
10:19 PM Tom_L: you'll forget how if you don't
10:19 PM zeeshan: i still machine from time to time
10:19 PM robotustra: "my pole is hard and made of steel" (c)
10:19 PM Wolf__: push cycle start
10:20 PM zeeshan: i wish i could get irc to work better
10:20 PM zeeshan: i'd come in here more often!
10:20 PM zeeshan: miss this place :D
10:20 PM robotustra: if you have a chunk of steel to scrape it
10:20 PM Tom_L: why doesn't it work?
10:20 PM zeeshan: it won't idle
10:20 PM zeeshan: it'll infinitely disconnect and connect
10:20 PM Tom_L: what client?
10:20 PM zeeshan: pissing everyone off
10:20 PM zeeshan: kvirc
10:20 PM Tom_L: try xchat or hexchat
10:21 PM Wolf__: set up znc on something
10:21 PM zeeshan: i tried xchat and did the same stuff
10:21 PM Tom_L: i still use mirc on this one
10:21 PM zeeshan: hexchat i can try
10:21 PM zeeshan: haha mirc :D
10:21 PM Tom_L: started using it and just kept on..
10:21 PM Tom_L: i have hexchat on it too as well as all the other pcs
10:21 PM Wolf__: someone slap tom with a trout
10:22 PM Tom_L: hah, i forgot about that
10:22 PM zeeshan: lol
10:22 PM Tom_L: the logs just got so big i just keep it now
10:23 PM Tom_L: this one's 135k
10:25 PM Wolf__: I’m working on setting up ZNC on my NAS box =)
10:25 PM Wolf__: that way I wont have 4 nicks in here
10:25 PM TurBoss: have you tried the matrix?
10:25 PM TurBoss: :)
10:26 PM * TurBoss from pc
10:26 PM * TurBoss from mobile
10:27 PM TurBoss: and keeps logs
10:29 PM * hazzy-lab seconds that
10:29 PM hazzy-lab: matrix is awesome
10:29 PM TurBoss: saying that from irc lol
10:29 PM hazzy-lab: xD
10:29 PM TurBoss: :P
10:30 PM hazzy-m: better?
10:30 PM TurBoss: yes!
10:39 PM Crom: `Wolf: alpha_min_endstop 1.24! # I have a PNP inductive hooked to this. When active it shorts to ground. is this right?
10:40 PM Crom: been trying to get my Linuxcnc and the ethernet mesa board going... no joy so far. So I have my smoothieware hooked up.
10:54 PM justan0theruser is now known as justanotheruser
11:58 PM * roycroft wonders when the bots will finally give up
