12:00 AM pink_vampire: 404
12:02 AM Wolf_: weird works here
12:02 AM Wolf_: http://imgur.com/yb7MRcf
12:02 AM pink_vampire: it is redirect to here https://i.imgur.com/original/y/b/7/M/yb7MRcf
12:02 AM X704 is now known as tiwake
12:02 AM Wolf_: opened fine as well
12:02 AM pink_vampire: now i got it
12:03 AM pink_vampire: what is all those squares?
12:03 AM pink_vampire: Wolf_:
12:03 AM Wolf_: 1” grid for sighting
12:04 AM pink_vampire: it's a target?
12:04 AM Wolf_: yup
12:05 AM pink_vampire: i zoom a bit and i see the holes in the paper
12:26 AM pink_vampire: http://i.imgur.com/QwgAur0.png
12:27 AM pink_vampire: any idea how to machine that part
12:28 AM * Wolf_ suggests using a mill
12:28 AM pink_vampire: l0l
12:28 AM pink_vampire: hot to hold it..
12:28 AM pink_vampire: how*
12:29 AM pink_vampire: it is very small part
12:30 AM Wolf_: looks like a pain in the ass, I see at least 4 setups to do it
12:30 AM pink_vampire: i need to get a 5 axis machine
12:32 AM pink_vampire: it has a curve surface
12:52 AM LeelooMinai: Maybe it can be redesigned - looks weird
01:31 AM IchGucksLive: Morning from Germany
01:32 AM IchGucksLive: pink_vampire: still on
01:34 AM pink_vampire: yes
01:34 AM pink_vampire: IchGucksLive:
01:34 AM IchGucksLive: 5-axis cool
01:34 AM IchGucksLive: i like to use a Arm CNC with UCP
01:34 AM IchGucksLive: let me show you
01:35 AM pink_vampire: I'm half way to the shower
01:36 AM pink_vampire: you will be here in an hour?
01:36 AM IchGucksLive: http://heimwerkermarkt-tretter.de/EF_AL.mpg
01:37 AM IchGucksLive: im off now it is made of redy parts using Bosh rexrodt
01:37 AM IchGucksLive: there is no backlash and no space on the junktions
01:38 AM IchGucksLive: Stiff to go for AL
01:38 AM IchGucksLive: ok im off 2
02:25 AM Deejay: moin
02:29 AM MrSunshine: hmm how hard would it be to make a ball bar for home testing purposes ... i guess it wont have the same accuracy as a commercial one but :P
02:29 AM MrSunshine: looks like two steel balls, magnetic seats and a high precision potentiometer ?
02:31 AM archivist_herron: whats the pot for
02:33 AM MrSunshine: to read voltage value .. aka roundness when moving around it the center point =)
02:34 AM archivist_herron: LVDT
02:34 AM archivist_herron: not a pot at all
02:36 AM archivist_herron: LVDT gives you near infinite resolution, against wire size and other errors in a pot
02:38 AM archivist_herron: MrSunshine, http://www.mikesflightdeck.com/lvdts/lvdts.html
02:39 AM archivist_herron: texas has an example of one of their chips as a lvdt reader
02:59 AM Crom: sheeshz... pngtopnm, then autotrace to svg, then I get to fix the autotraced svg, then I get to stitch them back together
03:00 AM MrSunshine: archivist: hmm ok =) interesting =)
03:01 AM archivist_herron: MrSunshine, reason I was exploring is I have a cmm probe that has 3 lvtds in it
03:01 AM Crom: or a strain guage could be rigged
03:01 AM archivist_herron: strain have limits to movement
03:03 AM archivist_herron: images of the probe http://www.collection.archivist.info/searchv13.php?searchstr=probe+PD+lvdt
03:03 AM Crom: you put a spring in there...
03:03 AM Crom: you preload it, then log the stain guage output
03:04 AM archivist_herron: you then cause force against what you are measuring, none from LVDT
03:05 AM archivist_herron: that probe uses spring mounting by the way :)
03:08 AM MrSunshine: mm... lvdt i think is the best choice here =)
03:10 AM archivist_herron: I thing Renishaw does that I think, one could use optical scale too
03:20 AM archivist_herron: time for an arduino version of http://www.renishaw.com/en/ballbar-testing-explained--6818 transmitting to linuxcnc
03:25 AM pink_vampire: hi archivist_herron
03:26 AM archivist_herron: allo
03:27 AM pink_vampire: did you saw the part that I made?
03:28 AM pink_vampire: http://imgur.com/a/Lcpjh
03:29 AM pink_vampire: archivist_herron: this is the part with he m2 thread and the j-b weld fix
03:33 AM archivist_herron: looks like there is space for larger size screw
03:33 AM pink_vampire: maybe.. but i like the M2 is more elegant look
03:37 AM pcw_mesa_ is now known as pcw_mesa
04:21 AM gonzo_: open question for you all...... huanyang VFD, tripping an RCD. Anyone have any experience/suggestions?
04:22 AM pink_vampire: gonzo_: what is rcd?
04:22 AM gonzo_: works on an isolation transformer and it's not a neutral-earth issue, as I only get a trip when switching the live feed in.
04:22 AM gonzo_: at the mo, I guess a 30ma, B curve
04:22 AM archivist_herron: GFI is american for the same device
04:23 AM gonzo_: ta for the translation
04:23 AM Loetmichel_: gonzo_: its usually the Filters that trip the (30mA?) RCD
04:23 AM archivist_herron: it measures the balance of live neutral, some filters in the VFD are the cause
04:23 AM Loetmichel_: if you can switch them off on your VFD: try that
04:24 AM Loetmichel_: the supply EMI filters i mean
04:24 AM gonzo_: looking through the vents I can only see some caps/mov's on the input
04:24 AM gonzo_: not had the case off it to dig deeper
04:25 AM Loetmichel_: no switch there to deactivate the filter?
04:25 AM archivist_herron: or use a higher rated rcd suitable for for a filtered line
04:25 AM Loetmichel_: the caps are the culprits
04:25 AM Loetmichel_: if its a single phase VFD
04:25 AM pink_vampire: gonzo_: it's connect to the ground?
04:25 AM Loetmichel_: they create a current to the ground
04:25 AM gonzo_: I will be changing the RCD for a C curve. But I suspect that will only affect the overcurrent trip time. Rather than any inbalance
04:26 AM gonzo_: this is a 3ph output and 1ph/3ph input
04:26 AM Loetmichel_: is it single phase input or three phase input?
04:26 AM Loetmichel_: and is it wired 1ph or 3ph?
04:26 AM gonzo_: you wire the incoming phase/neutral to two of the 3ph inputs
04:26 AM archivist_herron: because the caps are equal the currents are unequal
04:27 AM Loetmichel_: archivist: exactly. but only if wired for single phase
04:27 AM gonzo_: I did wonder about the unequal caps. Haven't drawn out the cct yet to think it through
04:28 AM pink_vampire: gonzo_: the RCD will tripped if you have a device that leak in to the ground
04:28 AM archivist_herron: pink_vampire, its the VFD filter that does it
04:29 AM pink_vampire: archivist: that mean that it is faulty.
04:29 AM gonzo_: quick scetch out, I'd think that the diodes in the unconnected phase terminal would be isolating the cap on that unused termin al
04:29 AM gonzo_: so the cap leak should be in balance
04:30 AM archivist_herron: it wont be in balance due to neutral being near ground
04:30 AM Loetmichel_: pink_vampire: nop
04:30 AM enleth_ is now known as enleth
04:30 AM pink_vampire: probably some short between something to the case.
04:30 AM archivist_herron: I suggest a transformer to fix it
04:31 AM Loetmichel_: if you wure a 3p inout to single phase the filter caps sit on Y with ground. So they will send a small current to ground
04:31 AM Loetmichel_: enough to trip some overly sensitieve RCDs
04:31 AM Loetmichel_: wire
04:32 AM gonzo_: assuming (still to be conmfirmed) that the input suppression caps are directly on each phase input to ground, then the phases I am connecting my single phase and neutral to, should be in balance. And the third unused phate input will be out of play, due to the disodes on the main rectifier
04:32 AM pink_vampire: add a resistor as current limiter?
04:32 AM Loetmichel_: gonzo_: the caps are only "balanced" if its 3 phase
04:33 AM archivist_herron: gonzo_, yes but your incoming live is far from ground but the neutral is not
04:33 AM Loetmichel_: a single phase cant have a "virtual neutral" generated by the 3 caps
04:33 AM archivist_herron: thus the loss of balance
04:33 AM gonzo_: ah... archivist_herron, ah, ok. Good point
04:33 AM archivist_herron: you can by adding a transformer
04:33 AM Loetmichel_: thats the only time the three currents tru the caps equalize each other
04:34 AM gonzo_: I was assuming that the N-E link at the company earth being on the supply side of the rcd would make it irrelevent. Bot that is wrong
04:34 AM gonzo_: co. meeting
04:34 AM gonzo_: brb
04:35 AM archivist_herron: Loetmichel_, there was an inverse of this problem in ##electronics the other day with a balanced generator and human connecting one leg to ground, knocking his breaker out
04:36 AM Loetmichel_: must have overlooked that ;)
04:36 AM Loetmichel_: i read there, too
04:37 AM Loetmichel_: basicall what happens is that the 3 currents of the (star-connected) filter caps on a three phase cancel themselves out, so that neutral/groound is currentfree
04:38 AM Loetmichel_: with a single phase or one phase of three missing that doesent happen any more, so there is a (small) current thru the ground
04:38 AM Loetmichel_: which trips the ERCD if it reaches 30mA
04:38 AM archivist_herron: should create a why filters trip rcds page one day
04:38 AM Loetmichel_: there are some VFD that have lover value caps to counter that
04:39 AM Loetmichel_: and Omron VFDs sually have a "pull tab" where you can deactivate the filter caps
04:39 AM * Loetmichel_ had the same problem on my fist big mill
04:39 AM Loetmichel_: had to deactiovate it.
04:40 AM Loetmichel_: ... and put the VFD closer to the motor so less EMI generated...
04:40 AM Loetmichel_: resulted in THAT: http://www.cyrom.org/palbum/main.php?g2_itemId=4935&g2_imageViewsIndex=1
04:48 AM pink_vampire: I want to make some fun project
04:53 AM XXCoder: pink_vampire: you like computer, historic ones? because theres few interesting projects
04:53 AM gonzo_: back
04:54 AM gonzo_: I was suspecting the filter caps on the input. But wondered if they may typically be quite low values and high leak, given what comes after them!
04:55 AM gonzo_: the fix may be that I have to take a non RDC (or separate higher fault current RCD) into the workshop.
04:56 AM gonzo_: or snip the caps out and build an ofboard filter
04:56 AM archivist_herron: simple electronics maths will show you the ac current to ground for each
04:57 AM gonzo_: will have to get the unit apart and check it's layout and find the cap values (assuming they are caps)
04:57 AM archivist_herron: snip, buy/build an external filter
04:57 AM gonzo_: that is the brute method, but more reliable, as I can play with it
04:59 AM archivist_herron: wind the incoming onto a ferrite
05:02 AM Devilhol1 is now known as Devilholk
05:03 AM gonzo_: I play RF as well, and have buckets of ferrite rings/clip-overs
05:03 AM gonzo_: will prob get a big arsed schaffner filter and some ferrite
05:08 AM archivist_herron: what kind of RF?
05:09 AM XXCoder: wishing for wishes. https://www.geeksaresexy.net/2015/06/20/the-genie-comic/
05:19 AM gonzo_: ham stuff
05:20 AM gonzo_: mainly higher freq stuff. But even so, poluting the aether with electrical noise on any frequency goes against the grain
05:22 AM archivist_herron: I was a G8 but did not keep paying the fee
05:22 AM archivist_herron: 2M and 10GHz TV
05:23 AM gonzo_: they are doing 2mtrs TV now
05:23 AM gonzo_: it's a free licence now
05:24 AM archivist_herron: I know its free just not reapplied
05:24 AM gonzo_: there are even people doing 70MHz and 50MHz TV tx-ing. So DXTV, but a bit differently to traditional
05:24 AM archivist_herron: slow scan stuff?
05:25 AM gonzo_: low bandwidth digital. So fastscan, but a bit jumpy
05:26 AM gonzo_: (low bandwidth as in <500kHz)
05:26 AM archivist_herron: I wandered off to play with an outside broadcast TV lorry
05:26 AM gonzo_: my interest has mainly been satellite and some GHz terrestrial stuff. But the TV his getting interesting again
05:27 AM jthornton: morning
05:27 AM gonzo_: was that as employment or hobby?
05:27 AM gonzo_: morning
05:27 AM archivist_herron: hobby
05:28 AM archivist_herron: http://www.collection.archivist.info/searchv13.php?searchstr=pd+ob
05:29 AM gonzo_: there are a few of the BATC people who refurb old OB and studio kit.
05:29 AM gonzo_: yep, I have a feeling I've seen those pics!
05:29 AM archivist_herron: one of those images is at a BATC event
05:30 AM archivist_herron: time to retire properly and start playing again
05:32 AM gonzo_: I almost brought an OB van. It was a 4wd one, looking a bit like an ex-mil vehicle. But someone beat me to it
05:33 AM gonzo_: I stumbled on it a few years later, it was being used as a mobile workshop by a guy doing shop fitting
05:33 AM archivist_herron: they changed the road rules since I last had it on the road, was MOT exempt
05:34 AM gonzo_: it was knee deep in sawdust, but the guy did say that the reinforced top with deployable hand rails made an excellent raised platform, to save hiring scafholt
05:35 AM gonzo_: if you regiotsre it as a mobile laboratory, you can get exemption (well you clulkd)
05:35 AM gonzo_: could
05:36 AM archivist_herron: they changed the rules for fixed equipment, so that if the vehicle it is mounted on is normal then MOT required
05:55 AM XXCoder: oh yeah
05:56 AM XXCoder: my caliper sent off to be repaired
05:56 AM XXCoder: I got quoted 70 for repair
05:56 AM XXCoder: not too bad.
05:56 AM pink_vampire: digital?
05:56 AM XXCoder: yeah
05:57 AM XXCoder: blades was slightly bent
05:57 AM XXCoder: -.001" error at end of it
05:57 AM XXCoder: I wonder if they also grind inside to still retain zero
05:57 AM pink_vampire: why not to get a new one?
05:58 AM XXCoder: 130 bucks
06:00 AM pink_vampire: mititoyo?
06:01 AM XXCoder: yeah
06:01 AM XXCoder: 130 bucks is on sale price
06:01 AM XXCoder: I handled it well for couple years then I acciently let it fall :(
06:04 AM archivist_herron: it is easy to fix yourself
06:05 AM XXCoder: how?
06:08 AM archivist_herron: small hand grindstone to remove the burr
06:09 AM XXCoder: its not a burr problem
06:09 AM XXCoder: the arms isnt parallel, it was 0 near and .001 apart at end
06:09 AM archivist_herron: I do it under a magnifier so I dont leave a bur or damage the measuring surface
06:10 AM archivist_herron: that is the gib screws
06:10 AM archivist_herron: adjust
06:11 AM XXCoder: yeah? hm though they said they was lapping some
06:12 AM XXCoder: how do you adjust gib screws?
06:12 AM XXCoder: just loosen and make sure its very clean and together then tighten or?
06:12 AM archivist_herron: small watch maker screwdriver
06:12 AM XXCoder: oh that I know, just method
06:13 AM archivist_herron: tighten enough to remove play but not stop movement
06:14 AM archivist_herron: I have seen a pair come loose often, needs a varnish or something on the thread to stop it undoing
06:15 AM archivist_herron: if company pays for you then all good
06:16 AM XXCoder: unfortunately no but its fine, it's still better than buying new
06:17 AM XXCoder: I'm still puzzled on my 1950s mic, it always worked well above .002 or so but below it has issues
06:17 AM XXCoder: I sent it off to re-certify, and when it returned it was perfect!
06:17 AM XXCoder: I wonder if they cleaned or something
06:26 AM archivist_herron: I use a bit of paper to clean the faces
06:26 AM XXCoder: me too
06:27 AM XXCoder: though it met at .0015 but rest of sizes past it was nice and accurate
06:27 AM XXCoder: now its accurate all way down and up
06:27 AM XXCoder: orginially I thought it was just threads slightly worn near end
06:51 AM XXCoder: https://www.youtube.com/watch?v=U7yn399bE1I pretty cool
06:51 AM mase-tech: Hi people :)
06:51 AM XXCoder: hey
06:52 AM mase-tech: Thank you for Linux CNC
06:52 AM XXCoder: make donation
06:53 AM XXCoder: thats best way to thank really
06:54 AM mase-tech: Agree. The problem is my girlfriend taking all my money :(
06:56 AM XXCoder: oh well
07:02 AM MacGalempsy: mornin
07:03 AM jthornton: yo
07:03 AM MacGalempsy: whats shakin?
07:03 AM XXCoder: https://www.youtube.com/watch?v=5c_gM1_jDgY
07:03 AM XXCoder: vacuum hold. uses bowden conenctor apparently.
07:03 AM gonzo_: need a nore cnc compatible girlfriend
07:04 AM gonzo_: more
07:04 AM XXCoder: machine one. ;)
07:04 AM gonzo_: just be sure to debur those edges!
07:05 AM XXCoder: lol
07:05 AM MacGalempsy: a gf that is gcode compatible? or one who likes cnc?
07:06 AM MacGalempsy: jt how did the drones finish up?
07:08 AM jthornton: the two small ones are done the big one is not done yet, I'm thinking of trying to fit the GPS thing to the 5"
07:08 AM MacGalempsy: a big antenna?
07:09 AM jthornton: not really about 1" square
07:09 AM MacGalempsy: the SLB guys have these giant Li Ion batteries that are 6'
07:10 AM MacGalempsy: they are line 80Ah and 24v
07:10 AM MacGalempsy: they would make a hellova dromm
07:10 AM MacGalempsy: drone batttery for some giant motors
07:11 AM gonzo_: in open field conditions you can get away with tiny GPS antennas
07:12 AM MacGalempsy: they are pretty dangerous tho. one tech blew his arm off
07:12 AM XXCoder: self-exploding drones
07:12 AM jthornton: damn that is dangerous
07:13 AM jthornton: https://www.youtube.com/watch?v=3rB_5cJLjLY
07:16 AM MacGalempsy: is that what you are using now?
07:16 AM jthornton: that's the one I have for the hex and I'm thinking of putting it on the quad for now
07:17 AM MacGalempsy: that should be fun. any ideas for the hello world flight?
07:18 AM jthornton: not given it any thought yet
07:19 AM XXCoder: MacGalempsy: yeah pathway to create literal "hello world" lol
07:19 AM XXCoder: its law
07:19 AM MacGalempsy: that would be cool. with some skoke
07:19 AM MacGalempsy: smoke
07:20 AM XXCoder: lol yep
07:20 AM XXCoder: off I go, to prend to be dead for around 8 hours
07:20 AM jthornton: goodnight
07:20 AM MacGalempsy: yeah. i need to too. just got off shift
07:21 AM MacGalempsy: mas tarde!
07:25 AM gonzo_: I do that pretending to be dead for hours. It's called being at work
08:07 AM Hawku-fr is now known as Hawku
08:47 AM Vq_ is now known as Vq
08:55 AM mase-tech: TBTB6600 or TB6560 should be the same ?
08:55 AM mase-tech: TB6600
08:57 AM howto: hi
08:58 AM JT-Shop: same but different I'd guess
09:00 AM mase-tech: I found TB6560 in Linux CNC wiki
09:08 AM howto: i can manual control the axis but when i run the example program i see some movement then imediately nothing
09:11 AM archivist_herron: howto, any error messages?
09:11 AM howto: nope it is just like it would normally work linuxcnc shows movement but no cnc movement
09:12 AM howto: except when i play manually with the axes
09:12 AM howto: no error messages
09:12 AM howto: archivist_heron no error messages
09:12 AM archivist_herron: you forgot to wire the enable?
09:13 AM howto: where is that?
09:14 AM howto: i have a cooltool basic 540 it doesnt have any feedback...except if the controller is on or off in the dos program...in linuxcnc not even that
09:14 AM archivist_herron: I have no idea what that model means
09:15 AM howto: archivist_heron what enable wire on a cooltool basic 540?
09:16 AM archivist_herron: well I cannot read your docs from here
09:18 AM archivist_herron: I give them 1/100 for online info http://www.thecooltool.com/en/products/pro-cnc-applications/
09:26 AM howto: archivist_heron the only feedback that the thing has is the controller poweron or off warnning in the DOS program
09:26 AM howto: in linuxcnc it doesnt have that either
09:26 AM howto: even that....sorry
09:27 AM howto: on the expert version it has the rest of the things
09:27 AM archivist_herron: not feed back it is a signal to the controller if fitted
09:29 AM howto: when IchGucksLive comes back to the chat, he will shed some light on the matter he brought me until here
09:29 AM howto: i hope he comes back
09:43 AM howto: archivist_heron iam tryin to run the example program....somewhere in the comments it says it is not intended for real cnc but if touch of is commenced it should work...i still think that the latency issues are interferring with the functioning of the machine
09:43 AM howto: my paralel port is set to ECP should i change that?
09:52 AM TekniQue_ is now known as TekniQue
10:19 AM howto: i will try to change the parallel port mode from ecp to something else
10:44 AM howto: ok i hit runtests script and all tests run ok
10:44 AM howto: i hit torun the example program again one axis starts to move about half a second then nothing
10:45 AM howto: when i hit the stop program some axis moves as if were decelerating
10:45 AM howto: and that's it
10:46 AM howto: archivist_heron look three rows up please
10:48 AM Loetmichel: howto: speeds way to high?
10:56 AM howto: no
10:57 AM howto: it starts about half a second then linuxcnc contnuing to do its thing but the machine hangs
10:59 AM howto: Loetmichel when i press the square button to stop the program some axis starts to function at the machine but ....as it would normally stop by decelerating ...for about half a second...and thats it
10:59 AM howto: after the start for about half a second described earlier
11:00 AM howto: so the program goes like this.....play program...some axis starts to do its thing for about half a second to a second...then the machine stops doing anything...the linuxcnc software continuing to do its thing in the meantime....
11:01 AM howto: when i hit the stop button.....some axis starts to do something from high speed to complete stop this in about a second
11:03 AM howto: IchGucksLive......helped me to even start the thing
11:04 AM howto: i have it for about 4 months doing nothing
11:05 AM howto: Loetmichel now do you understand what happens?
11:06 AM howto: it is like a music vinil where you start to play it and suddently the needle goes up the plate...after the vinyl starts to stop...the needle goes back on the plate..and you get one or two seconds of music at the start....and at the end
11:22 AM archivist: howto, set too fast, the steppers lose it
11:23 AM howto: archivist...how to set them slower?
11:24 AM TurBoss: hello
11:24 AM howto: hello
11:24 AM archivist: the same way you set them too fast
11:24 AM JT-Shop: lol
11:25 AM howto: archivist i do not know the program is as is installed
11:25 AM howto: i did NOT set anthing
11:25 AM howto: anything
11:26 AM archivist: you used stepconf probably and there was an option to set your max speed
11:26 AM archivist: you must have set up something alse you would not be at the stage you are
11:27 AM howto: no IchGucksLive gave me a new hal file....it didnt work until he gave that file and he made sure that pin2 was set where it needs to be
11:27 AM gonzo_: question for the mesa-hm2 experts.... the 7i90_epp_svst4_8_ado firmware..... what's the ado bit? I assumed an analogue output. But can't see how it's used.
11:30 AM howto: archivist....in configs...by_machine.....cooltool there is a standard-pinout.hal file that was modified by IchGucksLive...thats it....
11:30 AM archivist: s
11:30 AM howto: so if there is an option in axis to set steppers speed slower tell me
11:31 AM archivist: so it is not correct, YOU need to edit it and the ini
11:32 AM howto: archivist you need to tell me where i find the file to edit.....i am not a linuxcnc expert
11:32 AM howto: is the file in the cooltool folder?
11:32 AM pcw_home: gonzo_: its a copy paste mistake (the xxADO pinfiles are only for the 4I69's built in A-D Option so there should not be a 7I90 version)
11:33 AM archivist: howt I cannot see your disk, have you looked
11:33 AM howto: archivist...is the file in the cooltool folder?
11:33 AM archivist: I cannot see
11:33 AM howto: well you run linuxcnc no?
11:33 AM howto: in what folder is it yours?
11:34 AM archivist: on three machines
11:34 AM archivist: where ever I put it
11:34 AM howto: is the file in the machine brand folder?
11:34 AM howto: then i did not made such file archivist
11:34 AM archivist: try looking and not expecting us to wet nurse you through it
11:35 AM howto: archivist if you know something tell ...but if not please stop playing hide and seek with me...i am very tired...
11:36 AM archivist: oh dear off to bed then
11:36 AM howto: sleep tight :)
11:37 AM archivist: remember I am working for free, you have to put in some effort
11:37 AM howto: no you are bothhering for free...this is not helping
11:37 AM howto: this is bullying
11:37 AM howto: just like most of the linux comunity
11:37 AM howto: like 90% of it
11:38 AM howto: but there are 10% that do want to help
11:38 AM howto: like the guy yesterday
11:38 AM archivist: http://linuxcnc.org/docs/2.7/html/config/ini-config.html
11:38 AM roycroft: if you think archvist is bullying then you don't know for bullying
11:39 AM archivist: far from it, I am trying to get you to try some self help
11:39 AM howto: ok roycroft...initiate bullying...just like the masons :))
11:39 AM archivist: we cannot do one to one help for everybody
11:40 AM roycroft: he's trying to get you to think for yourself
11:40 AM howto: after i put the machine up i will help others too
11:40 AM JT-Shop: I'm afraid howto doesn't want help he wants someone to do everything for him
11:40 AM archivist: it is an unreasonable expectation for the price
11:40 AM howto: hold on i am reading the fthing you sent me the link for
11:40 AM roycroft: for one thing, it's your system and you are the only one with hands and eyes on it
11:40 AM roycroft: at some point you need to understand it
11:41 AM TurBoss: ^
11:41 AM archivist: I cannot give you 10 years of linuxcnc knowledge in one liners on irc
11:42 AM roycroft: this reminds me of an ongoing discussion i've had with my boss for the past 20 or so years
11:42 AM howto: archivist the guy yesterday gave me 20 years....but he is not here now
11:42 AM howto: i need another twenty
11:42 AM archivist: in linuxcnc?
11:42 AM roycroft: boss: i want you to document how you diagnosed and fixed random problem x that we've never seen before and likely will never see again
11:42 AM roycroft: me: 1. learn unix
11:42 AM DaViruz: i don't think you received 20 years worth of knowledge if you're stuck at setting max speed
11:43 AM roycroft: that's the end of the discussion :)
11:43 AM howto: roycrofft you take money for a job....i do opensource stuff...stop being a commie
11:43 AM roycroft: until the next time, when we have random problem y
11:43 AM howto: roycroft
11:44 AM archivist: roycroft, impossible dream learn all of unix :)
11:44 AM roycroft: howto: coming here making false accusations and antagonising folks is not going to help your cause
11:44 AM howto: roycroft i do not have unix i have ubuntu
11:44 AM howto: roycroft stop being red
11:44 AM archivist: exceedingly similar
11:44 AM howto: black was better
11:45 AM roycroft: a better approach might be to be polite, listen, take the time to understand what you're being told, and apply that newly-gained information to resolving your problem
11:45 AM TurBoss: this remind me that I don't know how to set max speed outside stepconf
11:45 AM * JT-Shop wanders off for a turkey dog and sauerkraut
11:45 AM * TurBoss need to read the manua
11:46 AM TurBoss: *needs
11:46 AM howto: but when someone tells me to live in the 80's just to recover some time to learn knoledge..isnt that pure hate roycroft
11:46 AM JT-Shop: TurBoss: read your ini file too
11:46 AM TurBoss: sure
11:46 AM archivist: TurBoss, stepconf allows tou to play with your system to find a top speed and acceleration
11:46 AM * roycroft refers howto to the comments he made some moments ago
11:46 AM howto: when archivist just sends me to the haystack to look for some needle i never know if it is a needle?
11:47 AM archivist: and then shoves it in the ini
11:47 AM howto: roycroft ...i am trying to read here
11:47 AM TurBoss: but is stored in SCALE?
11:47 AM TurBoss: checking...
11:47 AM archivist: scale is not top speed
11:47 AM TurBoss: oh
11:47 AM archivist: its a gearing multiplier
11:47 AM howto: archivist....i am trying to read what you sent me although i know it is just a prank...you prankster you
11:48 AM archivist: stop those accusations, not wise
11:48 AM roycroft: howto: your feeble attempts at humor are not helping your cause
11:49 AM howto: they never do in linux comunity roycroft....expecially when commies with the belief that an aptitude is stolen not learned
11:49 AM howto: are just commies...so stop i am trying to read
11:51 AM howto: ok i see variables....but where is this ini file withinin the linuxcnc folder??????? that is the question
11:51 AM DaViruz: you mentioned a folder. have you looked if there is a ini file in it?
11:51 AM howto: there are more ...so which one i should open?
11:52 AM howto: in my case the cooltool directory
11:52 AM archivist: look in all, discover
11:52 AM cpresser_ is now known as cpresser
11:53 AM roycroft: howto: stop with the ad hominems, please
11:53 AM roycroft: especially when they make absolutely no sense :)
11:53 AM howto: it should be the one with my cnc in it or the header ones......archivist....so you can archive my frustrations?....wouldn't that be ambrosia for ya :))
11:55 AM howto: roycroft what in the name of..... linuxcnc....is ad hominem?...some type of.... ad?
11:55 AM TurBoss: ok got it
11:55 AM TurBoss: thanks
11:55 AM IchGucksLive: hi
11:55 AM howto: aah the saviour
11:55 AM howto: thank...spacetime
11:56 AM DaViruz: howto: so you can't even find out what ad hominem meens by yourself? come on now
11:56 AM howto: archivist you are dismissed
11:56 AM DaViruz: i'm not sure i've ever seen anyone less deserving of help
11:56 AM IchGucksLive: howto: hoe is it first bit break
11:56 AM roycroft: it's short for argumentum ad hominem
11:57 AM * roycroft introduces howto to two new concepts: "google.com" and "wikipedia.org"
11:57 AM howto: IchGucksLive after some playing with the machine i run the runtests script
11:57 AM howto: those passed ok
12:10 PM Loetmichel: DaViruz: i have seen a few
12:10 PM Loetmichel: but not many
12:10 PM Loetmichel: i was tempted to help him an hour ago when i left work... i am not any moe
12:20 PM JT-Shop: speaking of sauerkraut I need to start a new batch I'm on my last jar
12:20 PM roycroft: i haven't made sauerkraut in a while
12:21 PM roycroft: the last batch i made was fantastic
12:21 PM roycroft: i used red cabbage, and added a bunch of garlic and red hot peppers to it
12:22 PM JT-Shop: never tried red cabbage or garlic
12:23 PM roycroft: well after you make your next batch, try a small batch with red cabbage and garlic
12:23 PM JT-Shop: diced garlic or whole cloves?
12:23 PM roycroft: i used whole cloves, but smashed
12:24 PM JT-Shop: sounds good
12:24 PM roycroft: my pickling crock is 3 gallons
12:24 PM roycroft: iirc i used one head of garlic
12:24 PM roycroft: and i filled the crock about 1/2 full
12:24 PM roycroft: and not all that many hot peppers
12:24 PM roycroft: it doesn't take much to impart a lot of heat/flavor
12:25 PM roycroft: i should make some kraut
12:25 PM roycroft: this is the pefect time for fermenting - it's getting nice and warm
12:26 PM roycroft: country fair is coming up in a couple weeks - i think i'll make some as soon as the fair is over
12:31 PM nos__: https://youtu.be/QCqxOzKNFks
12:31 PM nos__: Sumo robots
12:33 PM Loetmichel: roycroft: isnt it a bit early ìn the year to harvest any kind of cabbage?
12:33 PM nos__ is now known as nos
12:34 PM roycroft: around here, yes
12:34 PM roycroft: but i don't grow my cabbage
12:36 PM Loetmichel: i see
12:37 PM Loetmichel: you only make sauerkraut of it?
12:48 PM IchGucksLive: Loetmichel: sauerkraut is growing outside the window
12:50 PM Loetmichel: IchGucksLive: i doubt it
12:50 PM Loetmichel: cabbage may be growing there
12:53 PM IchGucksLive: tomatos harvest since 14days
12:53 PM LeelooMinai: nos: lol...
12:54 PM LeelooMinai: Firrst I thought it's x2 speed or something
12:54 PM howto: IchGucksLive done
12:55 PM LeelooMinai: I also like how they have to wear leg armor there...
12:56 PM Loetmichel: nos: neat little bots. I have seen a few of such fights live and helped build a few of these bots.
12:56 PM Loetmichel: pretty crammed inside the small boxes
12:57 PM Loetmichel: and an awful lot of power going
12:57 PM * LeelooMinai imagines a veteran without a leg standing in the corner there
12:58 PM LeelooMinai: Is the board from metal? I wonder how they get the crazy traction they have there.
12:58 PM Loetmichel: we even made one with a vacuum pump that could suck the bot down to get more grip
12:58 PM LeelooMinai: Well, that's one idea...
12:58 PM Loetmichel: LeelooMinai: back when i helped it was just rubber tyres soaked in some sovent/sticky stuff
12:59 PM LeelooMinai: However, that leaves less room for other stuff.
12:59 PM LeelooMinai: Maybe gecko-like material would work:)
12:59 PM Loetmichel: LeelooMinai: on a track, yeah, has been tried, dont know how successful though
01:00 PM gonzo_: pcw_home, thanks. I assume that bitfile is actually just a svst-4-8 ?
01:00 PM LeelooMinai: Loetmichel: How about a drill to anchor it in place? :p
01:00 PM Loetmichel: against the rules
01:00 PM LeelooMinai: lol, I imagine.
01:00 PM Loetmichel: "no damaging of the ring surface"
01:01 PM Loetmichel: that includes no sandpaper or spikes on the wheels
01:01 PM LeelooMinai: Well, I saw marks done there at some point where they were going in circles, but I guess that was accidental.
01:02 PM Loetmichel: yeah, the rubber of the wheels is usually soaked in some solvent/plasticiser to get more grip so it rubs off quite easily.
01:02 PM Loetmichel: thats no damage to the surface tho
01:02 PM LeelooMinai: Like F1 cars:)
01:02 PM Loetmichel: it can be wiped off
01:02 PM sync: f1 cars do not have solvent in their tires tho
01:02 PM Loetmichel: more like dragsters
01:02 PM sync: they are just sticky compounds
01:02 PM LeelooMinai: Yes, but they have very soft tires that do not last long
01:03 PM sync: which is designed in, but yes
01:04 PM LeelooMinai: That summo competition is nice from the participant point of view, since robots are small and logistics are easy and replacing parts, etc. too, but from the spectator point of view less so.
01:05 PM LeelooMinai: Well, maybe in Japan it is more so, since they are into weird stuff like that, but it's not good for mainstream TV.
01:07 PM kyle____: hey LeelooMinai, I actually found something you might find interesting
01:07 PM kyle____: https://github.com/jcchurch13/Mechaduino-Hardware
01:07 PM kyle____: under Strategy, read point #2
01:09 PM LeelooMinai: kyle: You see, basically what I was saying yesterday. Yes, I was suspecting that they may be ways to calibrate to make it better.
01:09 PM LeelooMinai: they=there*
01:09 PM kyle____: yeah, which makes sense
01:09 PM kyle____: you could probably even add temp sensing and correct for that too
01:10 PM LeelooMinai: Right, it's the usual strategy - use circuits/processing to fix physical inaccuracies.
01:11 PM LeelooMinai: Usually the problem is that it needs some kind of semi-automated calibration procedure and this is a problem for mass-produced parts.
01:12 PM kyle____: sure, but for a hobbyist this is great
01:12 PM LeelooMinai: Right
01:12 PM kyle____: because the extra work of calibrating is totally worth it in order to save potentially thousands
01:12 PM LeelooMinai: One other corner they cut there is using ARM instead of an FPGA.
01:12 PM kyle____: which is also fine
01:13 PM kyle____: and definitely beats using AVR
01:13 PM LeelooMinai: Yes, may be. Though with FPGA you can scale it to much faster processing, latencies, etc.
01:14 PM kyle____: which a hobbyist will likely never need to reach
01:14 PM kyle____: tbh this might even be overkill for a hobbyist CNC mill
01:14 PM LeelooMinai: True hobbiest goes for overkill any time it's possible:p
01:14 PM kyle____: number of axes is irrelevant too since each motor runs itself
01:15 PM LeelooMinai: Also, I see it dates to 2015 or so, but are they even selling it at this point?
01:15 PM kyle____: I don't know, but it's open source so I was thinking of making my own PCB since I have a couple of these encoders
01:15 PM kyle____: already have a setup for producing PCBs :P
01:16 PM LeelooMinai: Right, well, hardware is the trivial part in this - it's more about firmware.
01:16 PM kyle____: if it does everything it claims, then it's pretty impressive already
01:16 PM LeelooMinai: kyle: What do you mean setup. You order them from fab:)
01:16 PM kyle____: nah, that's the boring way
01:16 PM kyle____: I have copper-clad board, black spraypaint, ferric chloride, and a laser cutter
01:16 PM LeelooMinai: kyle: No seriously, that's the right way...
01:17 PM kyle____: and even some kapton film for a solder mask
01:17 PM LeelooMinai: Doing it at home at this point is a bit "retarded" imo:)
01:17 PM kyle____: why? it's fun
01:17 PM kyle____: sure, I could easily order it, but there's really no fun in that
01:18 PM LeelooMinai: kyle: I did it all - etching, etc., but it's "fun" for very short time, and if you want to do anything neat nowadays, you will quickly move to densites, pitches, tolerances, etc. that will make your in-home setup useless.
01:18 PM kyle____: sure, but I don't plan to
01:18 PM LeelooMinai: Pff... :)
01:19 PM kyle____: it's useful for prototyping
01:19 PM LeelooMinai: kyle: At the beginning: http://imgur.com/pSqGqrB
01:19 PM kyle____: the journey is better than the destination imo
01:20 PM kyle____: which is why I'm casting my own lathe
01:20 PM kyle____: hmm imgur's not working too well at the moment
01:20 PM LeelooMinai: kyle: And not so much later: https://www.flickr.com/photos/100017731@N03/16227550363/in/dateposted-public/
01:20 PM IchGucksLive: hi JesusAlos
01:21 PM kyle____: nice
01:21 PM IchGucksLive: JesusAlos: what about hevy thunder in your way
01:21 PM LeelooMinai: kyle: Yes, but you see the problem there? :)
01:21 PM kyle____: sure, I haven't had any plans to do much with BGA though
01:21 PM kyle____: my favorite microcontroller is qfp :P
01:21 PM LeelooMinai: kyle: 4 layers and tolerances, etc. - say bye bye to your home setup:)
01:22 PM kyle____: absolutely, even 2 layers is tough
01:22 PM kyle____: making vias is also tough
01:22 PM kyle____: don't worry, I have no illusions about the capabilities of my home setup
01:22 PM LeelooMinai: Yes, nowadays the PCBs are cheap - designing them is still an art in a way, and tons other things you have to take care of, so I would not worry that you do not etch them at home - not a big deal.
01:23 PM kyle____: yeah, it's just that cost isn't really my motivation
01:23 PM LeelooMinai: Your nerd status will be still intact imo:)
01:23 PM kyle____: at this point it would've been far cheaper to just order some
01:23 PM kyle____: it's just the curiosity of doing it yourself
01:23 PM kyle____: I'd probably try making ICs if I could
01:24 PM LeelooMinai: kyle: Well, normally you don't "just order" - I mean you have to design everything, unless you just copy stuff, but now that's boring.
01:24 PM kyle____: yep
01:24 PM kyle____: also keep in mind that I'm young and have plenty of time to burn exploring these things
01:25 PM JesusAlos: IchGucksLive: Hi
01:25 PM LeelooMinai: kyle: I would concentrate more on assembling probably. You have reflow oven?
01:25 PM JesusAlos: I'm here working hard :)
01:25 PM kyle____: yep, modified an old broken toaster oven
01:25 PM kyle____: at least, began modifying...
01:25 PM JesusAlos: wiht our 30 degreed (:
01:26 PM JesusAlos: degrees
01:26 PM LeelooMinai: Right, good
01:26 PM kyle____: I think my main motivation for all this is that I work in a corporate environment all day and want to come home and be a high-tech caveman for a little while
01:27 PM IchGucksLive: JesusAlos: its 36 here outside
01:27 PM IchGucksLive: and over 40 in the room
01:28 PM kyle____: actually, even worse, because I'm a programmer so there's not much chance of hands-on stuff
01:28 PM LeelooMinai: kyle: "Corporate environment" - sounds like a jail:p
01:28 PM IchGucksLive: kyle___ programmers do wheer struff
01:29 PM kyle____: lol, it's okay, we're a pretty laid-back company so it's not as bad as it could be
01:29 PM IchGucksLive: bigger companys do mor wheer stuff
01:30 PM IchGucksLive: like johndeer on sunday
01:30 PM LeelooMinai: IchGucksLive: Wheer-what? :)
01:30 PM IchGucksLive: all the mashines in the fields did stop at 10am to get a update
01:30 PM LeelooMinai: Is wheer German for weird? :)
01:30 PM IchGucksLive: unexpected things ;-)
01:32 PM LeelooMinai: Well, corporations have resources, but, you may end up as a disposable resource too, so a double-edged sword:)
01:41 PM kyle____: yeah, here I was thinking I'd never have to touch a VR headset again
01:41 PM kyle____: lo and behold I now have 3 on my desk again
01:42 PM LeelooMinai: kyle: You are a cerberus?
01:43 PM kyle____: nah, just one head, but they're different
01:43 PM kyle____: because they all have different input methods so I have to make sure they all work properly
01:54 PM JesusAlos: Wow 36? in Germany?
02:23 PM roycroft: finally
02:23 PM roycroft: i have everything i need for etching badges except the bottles to store the ferric chloride solution
02:23 PM roycroft: it just now shipped
02:23 PM roycroft: frustrating to be all ready except forthat
02:24 PM kyle____: waiting on things to be shipped is the bane of my existence
02:24 PM kyle____: we need teleporters now
02:24 PM roycroft: i'm pretty patient
02:24 PM roycroft: but i also generally have a good sense of what to expect
02:25 PM roycroft: and i timed my orders expecting things to show up roughly in a good sequence
02:25 PM roycroft: but the shipment of the bottles was delayed
02:28 PM eeriegeek: mason jars baby
02:28 PM roycroft: mason jars have metal lids
02:28 PM roycroft: which the etchant would destroy
02:30 PM roycroft: the ones i'm getting are hdpe, both bottles and lids
02:59 PM CaptHindsight: I often find that the liquid inside the plastic containers at the grocery store cost less than the bottles
02:59 PM CaptHindsight: when it comes to cleaners
03:39 PM tuppo: Can someone recommend a good CNC editor for Linux (Fanuc turning)?
03:39 PM XXCoder: lol https://youtu.be/QCqxOzKNFks
03:40 PM pink_vampire: XXCoder: funny
03:40 PM XXCoder: saw one do a burnout trying to push other lol
03:40 PM XXCoder: released some magic smoke
03:48 PM XXCoder: southwest too hot for planes to take off. dang
03:48 PM XXCoder: 120f
03:48 PM JT-Shop: ouch
03:49 PM pink_vampire: wow!!
03:49 PM Vitran: it has to do with the air pressure
03:49 PM Vitran: Bigger planes can take off
03:49 PM Vitran: but the small ones don
03:50 PM Vitran: 't have enough lift
03:50 PM XXCoder: actually ALL planes is grounded now
03:50 PM XXCoder: including bigger ones
03:50 PM roycroft: aviation official just don't want to be accused of discrimination
04:13 PM kyle____: I think the cost of linear bearings is exponentially related to their inside diameter
04:14 PM XXCoder: cost = q*r*2Pi, q is total of $ per mm, r is radius :P
04:15 PM XXCoder: if youre mean, change it to q^2*r*2Pi
04:16 PM kyle____: yeah you're probably right
04:16 PM kyle____: I'm not sure how well my lathe carriage would work with 20mm shafts
04:18 PM kyle____: some paper from thomson makes a claim of diameter:length of 1:24 being the max
04:18 PM kyle____: for unsupported rail, that is
04:28 PM Deejay: gn8
04:34 PM XXCoder: timt to work laters
04:39 PM JT-Shop: going in early?
04:58 PM nos: Loetmichel, LeelooMinai: They use a heavy steel plate and magnets!

07:52 PM GeneW_: any recommendations for diy laser cutter machine?
08:09 PM roycroft: so the first experiment with the citrus stripper went great
08:09 PM roycroft: a little scrubbing with a green scotch-brite pad and the piece is totally paint-free
08:09 PM * roycroft is pleased
08:09 PM roycroft: absolutely no fumes, and i can rinse the stuff down the sink safely
09:26 PM BeachBumPete: evening folks
09:33 PM BeachBumPete: anyone here knowledgeable about UPS accounts I gotta set one up so I can ship and receive my parts from anodizer without having to drive back and forth to get them LOL
09:35 PM BeachBumPete: makin parts on the CNC right now figured I would ask anyone else making anything interesting?
09:36 PM luna__ is now known as tiwake
09:37 PM malcom2073_: I was going to, but I seem to have lost my design :/
09:37 PM malcom2073_: I finally got some decent sized aluminum round, 4" and 10"
09:37 PM BeachBumPete: hehe how did you lose it?
09:39 PM malcom2073_: Switching between laptops since my primary got sent for RMA
09:39 PM malcom2073_: May have forgotten to back up my latest dev folder before I wiped it, can't seem to find it haha
09:39 PM malcom2073_: It won't take me more than a few hours to do it again, but it sucks anyway
09:39 PM BeachBumPete: damn that sux
09:39 PM malcom2073_: Was going to try to DIY a waterbrake
09:40 PM BeachBumPete: I ALMOST got the second airgun rifle stock drawing finished so I can FINALLY cut one. just a few more details on it
09:40 PM malcom2073_: Ah doing stocks now?
09:40 PM BeachBumPete: it is quite complex surprisingly lots of corners and pockets etc.
09:41 PM BeachBumPete: no just for me for now
09:41 PM BeachBumPete: I have two target rifles that need chunky target stocks
09:41 PM malcom2073_: If you build it, orders will come :-P
09:41 PM BeachBumPete: well I would maybe offer the service to inlet a blank for them but I do not want to get into machining custom stocks there is just not enough cash in it really
09:42 PM malcom2073_: Heh
