12:19 AM XXCoder: INSANE https://youtu.be/Koxzz7LDmEE
01:48 AM IchGucksLive: hi from sunny germany
01:49 AM IchGucksLive: XXCoder: i got a visit yesterday from california and she talked about so many fire
01:49 AM XXCoder: hey from no sun tacoma
01:50 AM XXCoder: fires happen each year
01:50 AM XXCoder: just expecially bad one this year
01:51 AM IchGucksLive: i hope it does not here as i life in middle of the foresrt
01:51 AM IchGucksLive: 60km wide and 200km long tree on tree
01:54 AM XXCoder: nice
01:55 AM IchGucksLive: im off 2 corn harvest day 3 about 100acre to go today
01:55 AM XXCoder: later
01:55 AM IchGucksLive: :P
02:21 AM Deejay: moin
03:08 AM gloops: missed Ichs..
03:09 AM gloops: anybody look at this and sort out the grounds for 0-10v signal and relay
03:09 AM gloops: https://postimg.org/image/lvyds4gat/
03:10 AM gloops: https://postimg.org/image/xnm92xax1/
03:13 AM gloops: only one ground pin there
03:13 AM gloops: been advised they must be seperate
03:14 AM CaptHindsight: it looks like it either work with 12V or Chinese currency :)
03:14 AM gloops: trust me to get the one with different labels to every other one on youtube haha
03:15 AM CaptHindsight: it only lists ONE Ground
03:15 AM CaptHindsight: pin 7
03:15 AM gloops: right
03:15 AM gloops: so im a bit confused
03:16 AM gloops: everyone else has vcm and dcm
03:16 AM CaptHindsight: can't be separate Grounds if there is only ONE Ground connection
03:17 AM gloops: right, ill wire them both to 7 then
03:17 AM gloops: and the 0-10v you think its 10vIN i want - pin 4?
03:18 AM CaptHindsight: it looks like it supplies a 5V or 12V to be used with a Pot for speed control
03:18 AM gloops: FWD is the relay i want 8
03:18 AM gloops: well its a 220v spindle, running from the panel straight to the mains
03:19 AM CaptHindsight: so the Pot would go betwween the 12V and Gnd with the wiper to the 10V in
03:19 AM CaptHindsight: or between the 5v and Gnd with the wiper going to 5V In
03:20 AM CaptHindsight: How would you like tp use it?
03:20 AM gloops: so i wouldnt be able to control with 0-10v from the breakout board?
03:20 AM CaptHindsight: tp/to
03:20 AM CaptHindsight: have the BOB pinout?
03:21 AM gloops: the way i want to work it is to control speed from linuxcnc through breakout board from the relay on/off and speed 0-10v pin
03:21 AM gloops: somewhere will have a look
03:21 AM CaptHindsight: where does the BOB get its 10V from?
03:21 AM gloops: the bob has a 0-10v pin
03:22 AM CaptHindsight: it "might" work with the BOB 10V out to the VFD 10V IN and the Grounds connected to each other
03:23 AM gloops: this is the bob and the wiring diagram Ichs gave - https://postimg.org/image/yv4s8vqf9/
03:23 AM CaptHindsight: I can't say since I don't know if tyhe BOB prvides its own 10V or if it just divides a 10V external input
03:24 AM gloops: Capt 10vin and connect grounds is the only way i can see, but i am an electronics illiterate
03:24 AM gloops: ichs vfd is a different layout
03:30 AM MarcelineVQ: a version of that board on aliexpress says this "note if you need to use the 0-10v output and signal input interface, you must connect a 12-24v power supply"
03:31 AM MarcelineVQ: connection details: https://ae01.alicdn.com/kf/HTB1hLeeIVXXXXa4XVXXq6xXFXXXG/201667421/HTB1hLeeIVXXXXa4XVXXq6xXFXXXG.jpg
03:31 AM gloops: lol, this gets better
03:31 AM MarcelineVQ: page I got that from https://www.aliexpress.com/item/CNC-mach3-Router-4-Axis-Kit-TB6600-3-Axis-Stepper-Motor-Driver-Controller-kit-4-5A/32290961744.html?ws_ab_test=searchweb0_0,searchweb201602_3_10152_10065_10151_10130_10068_10344_10342_10343_10340_10341_10139_10307_10137_10060_10155_10154_10056_10055_10054_10059_100031_10099_10338_10339_10103_10102_440_10052_10053_10142_10107_10050_10051_10326_10084_10083_10080_10082_10081_10178_

03:31 AM MarcelineVQ: fffuk, sorry
03:32 AM MarcelineVQ: Had no idea it was long
03:32 AM XXCoder: kidding
03:32 AM MarcelineVQ: let's nuke that metadata, https://www.aliexpress.com/item/CNC-mach3-Router-4-Axis-Kit-TB6600-3-Axis-Stepper-Motor-Driver-Controller-kit-4-5A/32290961744.html
03:33 AM gloops: well Ichs reccomended this board for the job, i suppose i could test the 0-10v pins see whats happening
03:34 AM gloops: i would rahter have had a dimmer switch than all this lol
03:35 AM gloops: PC power pack is 12v
03:35 AM MarcelineVQ: actually this is a nice little kit, just needs motors, hmm
03:38 AM gloops: $34 for board and 3 drivers is cheap enough
03:53 AM archivist: gloops, the two contacts on the relay are not connected to ground unless you want to
03:55 AM archivist: you need the 12v also for the limit switches
03:57 AM gloops: archivist ok, the relay, re this vfd, i connect to fwd - and what else? to make a circuit
03:58 AM gloops: https://postimg.org/image/lvyds4gat/
03:58 AM archivist: you can connect to the gnd pin 7
04:01 AM gloops: so relay from bob - to - 7 and 8 (gnd and fwd)
04:01 AM archivist: yes
04:01 AM gloops: ok thats clear enough
04:01 AM gloops: in hal i need parport 17 as the spindle cw
04:01 AM gloops: thats the relay for on off done
04:01 AM gloops: for speed, 10v In? pin 4 on the vfd
04:01 AM gloops: and same gnd as relay?
04:02 AM archivist: yes
04:03 AM gloops: right thanks ill give that a go
04:03 AM archivist: and you can use the 12v out as your supply
04:03 AM gloops: supply for what?
04:03 AM archivist: the bob 12v in
04:04 AM gloops: ok, so i connect 12v out on the vfd, that will supply 12v to the bob, through 12v in on the bob
04:04 AM archivist: yes
04:05 AM gloops: ok thats pretty clear, sorry to be so backward in this stuff
04:05 AM gloops: thats if the bob doesnt generate its own 0-10v without a 12v supply
04:06 AM archivist: it does not generate from thin air
04:06 AM gloops: see that makes sense now, but ichs made no mention of that
04:06 AM * archivist does not comment
04:06 AM archivist: :)
04:07 AM gloops: its probably so easy that someone who knows doesnt even think about it
04:07 AM archivist: one of mine http://www.collection.archivist.info/archive/DJCPD/PD/2015/2015_10_14_cnc_bob/IMG_2013.JPG
04:08 AM archivist: the small red thing upper left middle is the 12v supply in my case
04:10 AM MarcelineVQ: you use the same style board? popular item
04:10 AM archivist: that is a little isolated 5v to 12v so my vfd grounds are separated from the 5v
04:10 AM archivist: it just works for many people
04:11 AM gloops: taking a while to render
04:11 AM archivist: they all have oddities, this on fewer :)
04:11 AM MarcelineVQ: his webserver's a little slow is all, it'll get there
04:11 AM MarcelineVQ: or it's a huge image :>
04:11 AM archivist: server is fast adsl uplink is slow
04:12 AM archivist: worse when every one in a channel loads it
04:12 AM MarcelineVQ: ehe
04:12 AM gloops: grounding the 12v supply to the pwn gnd?
04:12 AM archivist: yes, it is identical
04:13 AM archivist: measure with your multimeter, it is connected
04:14 AM gloops: ok just to get this clear in my mind, - pin 17 on the bob is marked as the relay (or b axis dir) if i set the spindle cw/fwd in hal to pin 17 - this will activate the relay? pin 17 triggers the relay
04:14 AM gloops: and pin 1 triggers 0-10v
04:15 AM archivist: there are internal connections on the pcb,
04:15 AM gloops: from pin 17 to the relay?
04:15 AM archivist: yes via that link
04:15 AM gloops: so thats why i couldnt work out how to control the relay as it isnt a numbered pin
04:16 AM gloops: its not good when the spindle wont go but all this is learning lol
04:17 AM archivist: this makes it plain how to use p17 http://www.collection.archivist.info/archive/mirror/cnc/bob/bob_aliexpress.jpg
04:17 AM gloops: right
04:18 AM archivist: the usb port is the 5v supply
04:18 AM gloops: so if i wanted to use pin 17 for an axis control, id pull that jumper out
04:18 AM gloops: or could anyway
04:19 AM archivist: yes
04:19 AM archivist: choices
04:19 AM gloops: ill be professor of cnc wiring when this is done lol
04:20 AM archivist: I decline to comment
04:22 AM archivist: some of the bob's have isolated drives, which conflict with the opto in the stepper drive, must keep some scratching their heads for ages
04:23 AM gloops: its the same with modern cars, im fine, pretty good really with mechanical fixes, but the electronics is infuriating
04:23 AM gloops: days pass shrouded in mystery
04:24 AM archivist: I started in electronics with radio and tv in the late 1960's so been doing it a while
04:24 AM gloops: not something ive ever got into much, would like to learn but asusual, when you want to get something working, this isnt the time to be reading electronics for dummies
04:26 AM archivist: there is an expectation of ready done wiring diagrams but that is not possible for all the variations out there
04:26 AM gloops: too right
04:26 AM gloops: im pretty patient, i can see a lot of kids tackling this giving up
04:27 AM gloops: then again kids are probably more savvy with electronics, i dunno
04:27 AM archivist: some are like a duck to water some....not
04:28 AM gloops: standardisation is everything
04:28 AM archivist: pfft
04:28 AM parth1799: where i will get reverse-run-master2
04:28 AM parth1799: file
04:29 AM archivist: may need to fun master from git for that
04:30 AM archivist: github
04:30 AM the_wench: https://github.com/LinuxCNC/linuxcnc
04:30 AM parth1799: unable to find that file in linuxcnc
04:30 AM gloops: it seems whats happened in the world of cnc electronics, components designed for fitting by electrics technicians have been put straight on the public market with not much adapation for public fitting knowledge
04:30 AM gloops: if that makes sense
04:30 AM archivist: parth1799, no aware that it would be a separate file
04:31 AM gloops: this is like selling TVs in bits expecting joe public to assemble himself
04:31 AM parth1799: in linuxcnc where ? can any one guide me
04:31 AM archivist: I used to work for a kit maker
04:32 AM parth1799: i downloaded linuxcnc master but there is no such file like reverse-run
04:32 AM archivist: it wont be a "file"
04:33 AM archivist: google reverse run and linuxcnc to find it
04:33 AM parth1799: what it is ???? it is hal file or ini file???
04:34 AM archivist: I have never used reverse, just seen it discussed
04:35 AM parth1799: i got one link but it is not working right now "http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=shortlog;h=refs/heads/feature/reverse-run-master2"
04:36 AM archivist: we have moved to github
04:37 AM parth1799: yes....but now how can i get this ....and i want to run on it
04:37 AM parth1799: i want to run my gcode in a reverse
04:37 AM parth1799: direction
04:39 AM parth1799: can any one figure out this problem ???? i want to run gcode in reverse direction
04:40 AM archivist: you dont need to repeat a question, ask better questions
04:41 AM archivist: nobody can know what you mean by ????
04:43 AM parth1799: i am making CNC WEDM and i want to run my G-code in reverse direction i got from internet that motion adaptive feed can do it. but i read out that in motion adaptive feed i can pass value from 0 to 1 so its output is only stop and fwd run
04:43 AM parth1799: but i need reverse run so how can i get it
04:43 AM parth1799: i want to make a HAL file
04:43 AM gloops: mach 3 has reverse run
04:43 AM parth1799: for that
04:43 AM parth1799: nope
04:43 AM archivist: perhaps all you need do is find the documentation to use it
04:44 AM parth1799: mach 3 has no reverse run
04:44 AM gloops: http://www.microproto.com/software.htm
04:44 AM * archivist whacks gloops
04:44 AM gloops: lol
04:44 AM gloops: im sure linuxcnc can do it
04:45 AM gloops: youve only got to tell it to flip the line numbers
04:45 AM archivist: trouble is people code something and forget to document it
04:45 AM parth1799: ya but in this case i want to control its feedrate so some time it will run in fwd and some time it will run rev....
04:46 AM archivist: with the motion and trajectory planner it is not that simple
04:46 AM parth1799: mach3 is not a right way
04:46 AM gloops: anyway ive got some wiring to try again, while its fresh in my mind
04:47 AM slipalong_: Anyone recommend a tutorial on offsets the whole thing is spraying my brain
04:47 AM parth1799: archivist/gloops any solution you have????
04:47 AM parth1799: how to figure out this problem
04:47 AM parth1799: ??
04:48 AM slipalong_: Im sure I found a menu where you could set them but can't find it
04:48 AM gloops: no sorry, i havent had time to study these things yet
04:48 AM archivist: slipalong_, which offsets :)
04:49 AM slipalong_: G54 and all that stuff.
04:49 AM archivist: parth1799, also search for others that have done it and see what they did
04:49 AM slipalong_: Sorry m very new to CNC it a bit of a learning curve
04:49 AM slipalong_: Ive designed my parts centred on x0 y0
04:50 AM archivist: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?CoordinateSystems
04:50 AM slipalong_: so need to set X330 and y 100 offsets
04:50 AM gloops: so you have one square at 0,0 you want to cut 6 squares the same, using offsets can repeat the cut at specified intervals, for one thing
04:51 AM parth1799: if you will get any solution regarding that pls mail me parth1799@yahoo.com
04:51 AM archivist: on that wiki page Write to the G54 coordinate origin using "G10 L2 P1 X0 Y0 Z0". This overwrites the G54 origin with the given coordinates.
04:51 AM parth1799: thanks
04:52 AM slipalong_: Is there a way to write them into the presets on LCNC. I want to have a Vice and turntable perm bolted to my table
04:52 AM archivist: slipalong_, also one can just touch off on your part to set x/y
04:53 AM archivist: there are presets you can use
04:54 AM archivist: I find you have to move stuff to often to think of preset locations though
04:54 AM slipalong_: where are the presets. I don't understand touch off either yet. Next on the list!! Going to learn the gardway and break so endmills!
04:54 AM archivist: most important to try touch off :)
04:54 AM slipalong_: ok so touch off it a better option.
04:54 AM slipalong_: I will have a read Thanks,!!
04:57 AM archivist: last job I did was a sheet metal part, had to remove A and B fit vice and it was too long so multiple moves in the vice to get all the holes done
04:59 AM archivist: it is not till you have made a few things that you know what you will need
05:02 AM jthornton: morning
05:02 AM XXCoder: yo
05:04 AM XXCoder: yo
05:06 AM jthornton: figured out what the problem was with the coop door, I used an 8 conductor cable for motor, door lock, limit switches and the noise from the motor to the ardweeny inputs made it crash
05:07 AM XXCoder: doh
05:22 AM gloops: touch basically gives linux the position of your workpeice
05:22 AM gloops: touch off
05:23 AM jthornton: more specifically the tip of the tool
05:23 AM gloops: well yes, in relation to the work - and from home position
05:23 AM jthornton: in relation to the machine coordinate system
05:25 AM gloops: basically home the axis first, then touch off
05:26 AM jthornton: yes
05:26 AM XXCoder: is someone else besides gloop and jt talking?
05:26 AM gloops: im just trying to help here jthornton, it appears theres actually someone in the channel that knows less than me for once lol
05:26 AM gloops: was responding to slipalong - read line from 10 minutes ago
05:27 AM XXCoder: ahh
05:27 AM jthornton: I thought you were asking...
05:27 AM jthornton: just waking up here
05:27 AM jthornton: about time to wake the chickens up now
05:35 AM gloops: right finally getting a click from the board when i hit spindle forward..
05:36 AM gloops: but no spindle movement, no speed, so assume i do need 12v supply, have no seperate ground on vfd for that hmm
05:36 AM gloops: will try 12v out, no ground
05:38 AM gloops: no wait, not set vfd parameters back, try that ( just thinking aloud now yes)
05:38 AM jthornton: thinking aloud helps me too
05:41 AM gloops: bit stuck
05:43 AM * jthornton wonders what current transfer ratio for an opto is?
05:54 AM archivist: optos vary
05:55 AM gloops: archivist, if you have one second more
05:55 AM archivist: takes more that a second to drive up and fix it!
05:56 AM gloops: 12v output from vfd, can i use the ground on the vfd for that? common ground with pwn and relay
05:56 AM gloops: https://postimg.org/image/lvyds4gat/
05:56 AM gloops: im close here i know it, very close
05:56 AM XXCoder: the picture at bottom apparently was scam one. though if it was "real", the ride would be insanely rough. http://www.cdn.tv2.no/images?imageId=9380553&width=970&height=894&compression=100
05:56 AM archivist: you have one gnd on the vfd it is common with 12v etc
05:57 AM gloops: so wont get sparks
05:59 AM archivist: the hard thing looking at users sentences is working out what they dont know or need sometimes
06:06 AM archivist: remember I dont know id the fwd pin is active high or low
06:08 AM XXCoder: office trick. bit old but funny https://www.youtube.com/watch?v=AXQmnm7YqWo
06:12 AM gloops: ok, testing 0-10v pin on bob - when i change spindle speed on linux - 0-10v pin is changing on bob, so thats working to that point, thinking spindle parameter settings now
06:19 AM archivist: do you ground fwd pin or lift it high to run the motor
06:20 AM gloops: woohooo!!!
06:20 AM gloops: we have lift off!!!! haha
06:21 AM archivist: seeeee it was easy
06:21 AM jthornton: yea
06:21 AM gloops: final snag was parameter setting, was set for 5v signal not 10v
06:21 AM archivist: heh
06:21 AM * jthornton searches for an opto isolated 5v relay diagram with part numbers...
06:21 AM gloops: seriously, i wouldnt have done this without the help in here
06:22 AM gloops: thanks to all
06:25 AM archivist: I want some nice machinable foam or something to hold renishaw bits in a box
06:34 AM XXCoder: archivist: work we get bunch of black foam, we reuse those as pin holder, tool holder, so on
06:35 AM archivist: what I dont want is that black foam that goes sticky
06:36 AM archivist: dont know what that is made of so I could search for the better
06:36 AM XXCoder: packing foam which is white is better but somewhat rare
06:36 AM XXCoder: black foam at work isnt sticky
06:36 AM XXCoder: its packing foam that is pretty rigid
06:37 AM Tom_L: JT-Shop, iirc i used about a 220 on my opto
06:37 AM Tom_L: 220 R
06:37 AM gloops: builders spray can foam, fill a container let it set, molds pretty well, or some rigid insulation board from wickes, larger sheets though
06:37 AM * jthornton waves at Tom_L
06:37 AM Tom_L: wire fixed it ehh?
06:38 AM jthornton: I've not replaced the 8 conductor with separate wires yet... I have to take the door out and rework it
06:38 AM gloops: you can get poly foam in liguid form with a catalyst, they use it for all kinds of grp filling, bit of a length to go to for one off job though
06:38 AM archivist: gloops I have used that, it's holing some windows and doors in
06:39 AM Tom_L: 330R ...
06:39 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/OPTO_Bottom.jpg
06:39 AM archivist: changes colour when old too
06:39 AM gloops: sound stuff archivist, quite close density
06:39 AM jthornton: I still want to make a special propose board for the door
06:39 AM Tom_L: as you should
06:39 AM Tom_L: chickens deserve the best!
06:40 AM gloops: and if your tool box falls in the sea - it will float
06:40 AM jthornton: https://app.box.com/shared/s67gb6lnqg
06:41 AM XXCoder: arch like this https://www.uline.com/BL_874/Polystyrene-Sheets
06:41 AM archivist: dont want polystyrene
06:41 AM * archivist is fussy for the best bits
06:42 AM Tom_L: and here i was thinking you drew that :)
06:42 AM gloops: polystyrene is compressed little balls, they seperate and stick to everything
06:42 AM jthornton: I wish
06:43 AM archivist: I should use felt lined beech really
06:43 AM Tom_L: you'd be halfway there... just create board from schematic and route
06:43 AM XXCoder: oh not that type
06:44 AM XXCoder: hm dunno what its called then
06:45 AM Tom_L: you might test the opto R value.. i used 330R on a 5v logic
06:45 AM Tom_L: is yours 3.3v?
06:45 AM archivist: I want just the box, I have the bits http://www.ebay.co.uk/itm/Renishaw-CMM-Extension-Set-/182384478380
06:45 AM Tom_L: either way won't change the board routing
06:46 AM gloops: simple pocketing job archivist?
06:46 AM jthornton: the esp8266 is 3.3v only, the nano is 5v
06:47 AM Tom_L: several ways to approach that
06:47 AM Tom_L: 1) run the nano at 3.3v
06:48 AM Tom_L: 2) put current limit resistors on each io to the esp
06:48 AM Tom_L: 3) get a level converter chip
06:48 AM jthornton: it's either one not both that will be used
06:48 AM Tom_L: oh
06:49 AM jthornton: for wifi control the esp8266 for RTC the nano
06:49 AM Tom_L: scratch all that then.
06:49 AM gloops: well bbl
06:49 AM jthornton: for now the nano and in the future switch over to the wifi one
07:39 AM fablab: hi peps
07:40 AM fablab: I want to use linux cnc for milling
07:40 AM XXCoder: cool
07:40 AM XXCoder: what machine etc
07:41 AM fablab: I have the electroniks and motors connected
07:41 AM fablab: I want to use linux cnc to let the motors drive
07:41 AM fablab: so i need a setup
07:42 AM archivist: stepconf builds a setup
07:42 AM fablab: I have TB6600 stepper driver with nema 23 motors and a china breakout board
07:42 AM XXCoder: that shouldnt be too diffult then
07:42 AM fablab: yes
07:42 AM fablab: i hope so
07:42 AM fablab: I mean it does not work so far
07:43 AM archivist: which breakout board did you use
07:43 AM fablab: the china breakout is connected with a lpt1
07:43 AM archivist: we need to know which breakout
07:44 AM archivist: there are many
07:44 AM fablab: ok mom
07:44 AM fablab: it has no name
07:44 AM fablab: i post a pic
07:45 AM archivist: does it look like http://www.collection.archivist.info/archive/mirror/cnc/bob/bob_aliexpress.jpg
07:45 AM fablab: 100% bingo
07:46 AM archivist: those usually work better to say what does not work
07:47 AM fablab: I made a upgrade on linux cnc to 2.7.11
07:47 AM fablab: the preconf wizard changed
07:48 AM fablab: hmm what u need to know
07:48 AM archivist: pncconf is for mesa cards stepcond for parallel port
07:48 AM archivist: stepconf
07:49 AM fablab: I think the problem is inside the setup
07:49 AM fablab: OK
07:49 AM fablab: i try again
07:50 AM fablab: a one more questen about the switches on tb6600
07:50 AM slipalong_: Anyone running a AMA25LV or equivilent
07:51 AM fablab: I want to run them 1/2 microstepping
07:51 AM fablab: and 1,2 A limit
07:52 AM fablab: no 1,8 A limit
07:53 AM fablab: so I put the switches on 001101
07:54 AM fablab: what should I pick for driver
07:55 AM fablab: archivist
07:56 AM archivist: we cannot know which particular driver you have read the label for switch positions and experiment
07:56 AM fablab: HY-DIV268N-5A
07:57 AM archivist: slipalong_, if they come from the same factory as others, you may need to adjust
08:04 AM slipalong_: Archivist, I have it all set up with steppers an ballscrews, but Im just setting up LCNC
08:04 AM slipalong_: was wondering it its best to have X0 id table so -330mm - + 330mm travel
08:05 AM archivist: slipalong_, I know a local who has the one from Arc Euro Trade, we have had the spindle apart to adjust the bearings
08:05 AM slipalong_: or maybe it make no different 0 - 660 mm X trvel
08:05 AM archivist: 0- whatever
08:06 AM slipalong_: no benifit either way OK
08:06 AM archivist: once you touch off you will be using +- around the point you touched off to
08:07 AM slipalong_: ah ok!
08:08 AM slipalong_: just working up to cutting some metal and don't want to distory anything!
08:08 AM archivist: cut air first, and see if proposed cuts fit in the bounding box
08:09 AM archivist: I am far enough north that nothing flying off will hit me :)
08:10 AM archivist: just about all of has an accident and bits do go flying
08:10 AM archivist: best I managed was about 40-50 ft
08:23 AM sync: slipalong_: it is best to setup the MCS according to din66217
08:27 AM slipalong_: so full body amor for the first cut then :-)
08:27 AM archivist: just do the vice up tight!
09:23 AM archivist: took a measurement at 14 deg c and another today at 16.5 deg .99982" at14, .99984 at 16.5, need a heater in that room :)
09:53 AM fablab: which voltage can I expect to measure on the signal pins?
09:53 AM fablab: 5V ?
09:54 AM archivist: fablab, the switch inputs on the breakout?
09:55 AM archivist: those are pulled up to the 12v supply
09:56 AM fablab: the breakout board is connected with lpt1 and usb port for 5V
09:57 AM fablab: the motor drivers are connected with 12V to supply motors
09:58 AM archivist: the board has separate 12v in, best not use the motor supply
09:58 AM archivist: unless you filter it
09:59 AM fablab: so i need the 5 v from usb and a seperate 12V
10:00 AM archivist: I use an isolated 5v to 12v inverter supply
10:01 AM fablab: pics or it didn t happen
10:01 AM fablab: :D
10:01 AM fablab: joke
10:02 AM archivist: pic it did happen http://www.collection.archivist.info/archive/DJCPD/PD/2015/2015_10_14_cnc_bob/IMG_2013.JPG
10:02 AM archivist: red upper left
10:02 AM fablab: thanks
10:07 AM fablab: ok
10:08 AM fablab: is think for testing I use 12V from atx
10:08 AM fablab: I want to see it moving
10:09 AM archivist: electrical noise from the motors on the 12v may be a problem later on your limit switches
10:09 AM archivist: 12v is a bit low for motors anyway
10:10 AM fablab: I have no limit switch connected
10:10 AM fablab: I show u the current stand

10:55 AM IchGucksLive: hi
10:57 AM IchGucksLive: AndChat569025: hi
10:57 AM IchGucksLive: why are ther so many cables
10:58 AM IchGucksLive: fablab: still online
11:05 AM IchGucksLive: AndChat569025: why did you connect ENA at all if you only want to test
11:05 AM IchGucksLive: AndChat569025: the lugs on the board are JST-XH-3s
11:06 AM IchGucksLive: they fit to the tb6600
11:14 AM fablab: andchat is me
11:14 AM IchGucksLive: i know
11:14 AM IchGucksLive: im the man behind the https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
11:15 AM IchGucksLive: i build about 25 mashines ased on that bob
11:15 AM IchGucksLive: a month
11:15 AM IchGucksLive: where is your problem

11:18 AM IchGucksLive: fablab: ? es geht auch in deutsch
11:18 AM Deejay: i dont understand you :(
11:19 AM IchGucksLive: Deejay: pälzer !
11:29 AM IchGucksLive: hi gloops
11:29 AM IchGucksLive: i read you got in trouble
11:29 AM IchGucksLive: how coudt that happen
11:29 AM IchGucksLive: on 4wire
11:30 AM AndChat569025: http://picpaste.de/1506355110473140578926-ujwpMDVn.jpg
11:30 AM gloops: spindle running Ichs, it is over lol, thanks for the help
11:35 AM gloops: my vfd ports dont look like yours - only one ground, but the diagram was helpful at least i knew what i was trying to do
11:36 AM IchGucksLive: good
11:36 AM gloops: also i didnt realise you had to have a 12-24v in on BOB, didnt take long when i got to that stage
12:55 PM IchGucksLive: gloops: it works so all is ok
12:55 PM IchGucksLive: but you dident follow my advice as yoiu frorgot the 12V
12:59 PM AndChat569025: Which is the right parallel port config in bios
12:59 PM AndChat569025: At, ps2, Epp, ecp
12:59 PM IchGucksLive: EPP
01:00 PM gloops: by hook or by crook it doesnt matter Ichs, i can move on finally
01:02 PM IchGucksLive: gloops: now the nativCam
01:02 PM gloops: as always, the minute you click and it works, it all looks so simple and you cant believe there was any problem
01:02 PM IchGucksLive: then the full motion
01:03 PM gloops: nativCam?
01:03 PM IchGucksLive: Lcnc internel CAD Cam
01:03 PM gloops: what does that do?
01:03 PM IchGucksLive: makes you the Gcode right on the CNC
01:03 PM IchGucksLive: from skretch sketch or dxf
01:04 PM gloops: ah so linuxcnc does do that
01:04 PM IchGucksLive: yes
01:04 PM gloops: is that a plug in?
01:04 PM IchGucksLive: from 2.7.9 it is in the repro
01:05 PM IchGucksLive: https://www.youtube.com/channel/UCjOe4VxKL86HyVrshTmiUBQ
01:05 PM gloops: ill look into that, i did find greyscale to depth map, but not had time to look at anything else - all my time been spent wiring this up
01:05 PM IchGucksLive: gloops: ary you going to sculp
01:06 PM MarcelineVQ: nativecam is fairly interesting https://www.youtube.com/watch?v=RZbI6kXSqr0
01:06 PM gloops: i will be at some point yes
01:06 PM IchGucksLive: gloops: let me do a image of the part a student made last week
01:07 PM gloops: ok
01:07 PM gloops: what i need is another drive setting up on this pc with linuxcnc installed, the other one isnt online in the garage yet
01:09 PM gloops: so i can have linuxcnc open and still be on here
01:10 PM MarcelineVQ: You definetly want to not be using your main computer for cnc, if you wire somethign up wrong it's bzzzt no more main computer
01:11 PM gloops: oh yeah, its only an old box im using for it, tbh i havent even checked if its picking router signal up it might be
01:12 PM gloops: oh no, i have - no wifi
01:12 PM IchGucksLive: gloops: http://heimwerkermarkt-tretter.de/engel.jpg
01:12 PM IchGucksLive: this is milled on a Education Chees with a 0,1mm bit
01:13 PM gloops: with nativecam?
01:13 PM IchGucksLive: no heekscad
01:13 PM gloops: ahh ok, very nice piece
01:14 PM gloops: some fine detail in the borders there, cut that nicely
01:14 PM MarcelineVQ: IchGucksLive: thanks for this link to your channel by the way, lotsof useful looking vids
01:15 PM fablab: thx for help
01:16 PM IchGucksLive: its a 0,05mm path at 2400mm/min
01:20 PM IchGucksLive: im off Gn8
02:38 PM CaptHindsight: http://www.ebay.com/itm/50-SETS-JST-XH-2-5-4-Pin-Battery-Connector-Plug-Female-Male-with-120MM-Wire/252044068639 low cost and fit the connectors on the popular ChinaCo BOBs
02:38 PM CaptHindsight: unfortunately the wire leads are not very long
02:39 PM CaptHindsight: $8 with shipping for 50 sets
02:45 PM MarcelineVQ: good find though
02:52 PM gloops: well, i was dozing on the settee yesterday, flicked the TV on and Dambusters was on
02:52 PM CaptHindsight: http://www.ebay.com/itm/50-kits-XH2-54mm-2-3-4-5-6-7-8-pin-JST-Connector-plug-Male-Female-Crimps-DIP-/142147287890 if you wish to crimp your own
02:54 PM gloops: and it was just the same today, i tried and tried and it didnt work, and then after the thousandth attempt - there it was
02:54 PM CaptHindsight: you found the magic smoke?
02:54 PM gloops: no, the spindle started turning lol
03:16 PM sadisticroot: CaptHindsight: why not just cut some off old ATX power supplies?
03:16 PM sadisticroot: heh
03:20 PM CaptHindsight: if you have old power supplies
03:21 PM Deejay: gn8
03:40 PM CaptHindsight: sadisticroot: which old ATX supply connectors did you find that matched?
03:40 PM sadisticroot: Nevermind, I thought they looked like floppy connectors but they're a bit different
03:42 PM CaptHindsight: pins are smaller
03:42 PM CaptHindsight: 2.54mm space
03:43 PM CaptHindsight: the floppy connectors had thicker pins
03:47 PM Loetmichel: CaptHindsight: not by much
03:48 PM Loetmichel: actually the floppy connectors fit the normal "pin header" females pretty good.
03:48 PM Loetmichel: the 3.5" that is
03:48 PM Loetmichel: the 5.25" and 8" have/had 4 pin molex like ATA HDDs
03:59 PM CaptHindsight: the PCI connectors are completely different :)
04:02 PM Loetmichel: of course
04:03 PM Loetmichel: so are the Atx12V cpu connectors
04:04 PM Loetmichel: but a floppy connector has pretty much noting in common with an XH2
04:05 PM Loetmichel: floppy power uses 2,54mm grid
04:05 PM CaptHindsight: 1/4" pipe nipples
04:05 PM Loetmichel: and a different body
04:05 PM Loetmichel: <- has crimped both by the gros so i can tell the difference pretty well ;)
04:06 PM CaptHindsight: Loetmichel: do you have a source for the JST XH 2.54mm 4 pin connectors?
04:07 PM Loetmichel: not out of the head. must look in the database at the company tomorrow.
04:07 PM Loetmichel: but it will likely be a german source, dont see that as much use to you ;)
04:08 PM CaptHindsight: http://www.jst-mfg.com/product/detail_e.php?series=277 this says 2.5mm pitch
04:08 PM CaptHindsight: doesn't matter too much for a few pins
04:10 PM CaptHindsight: Loetmichel: it might help someone there
04:10 PM CaptHindsight: I never see the cables offered with the BOB
04:11 PM Loetmichel: CaptHindsight i think it doesent matter for less than 20 pins or so
04:11 PM Loetmichel: the 2.5/2.54 difference
04:14 PM CaptHindsight: 20 pins max for the series
04:15 PM CaptHindsight: so the ebay listings are just wrong, no surprise there
04:15 PM CaptHindsight: they are the right connectors
04:15 PM CaptHindsight: they just mention the wrong pitch
04:16 PM CaptHindsight: 2.5 and 2.54mm are the same thing in China anyway, just ask them
04:18 PM Loetmichel: pretty much ;)
04:18 PM Loetmichel: tolerances isnt their thing
04:18 PM Loetmichel: stell quality in screws neither it seems
04:19 PM Loetmichel: <- got a delivery of a few 100 custom 24" TFT steel enclosures lately... each "fixed" together with a few M3 screws
04:21 PM Loetmichel: every second screw doesent want to screw out. and when i take my leatherman wave and grip the screw head sideways with the needle nose pliers to turn them loose i already FLATTENED about a dozen screw heads. ONE HANDED. what material do they make these screws out of?
04:21 PM Loetmichel: cant be steel, can it?
04:22 PM CaptHindsight: remarkably soft steel
04:24 PM DaViruz: Loetmichel: cheese
04:24 PM DaViruz: or so the joke goes at least :)
04:25 PM Loetmichel: DaViruz: can second that. or lead. at least it feels that way ;)
04:25 PM Loetmichel: <- doesent look like hulk at all ;)
04:26 PM Loetmichel: <doesent get green when angered either
04:26 PM Loetmichel: :-)
04:43 PM gregcnc: capthindsight no stock https://www.digikey.com/product-detail/en/jst-sales-america-inc/ASXHSXH22K305/455-3241-ND/6684932
04:45 PM CaptHindsight: hmm, odd that they sell a pre-crimped pin and wire
04:47 PM CaptHindsight: https://www.digikey.com/product-detail/en/jst-sales-america-inc/XHP-4/455-2267-ND/683353 just the 4 pin connector without contacts
04:48 PM CaptHindsight: https://www.digikey.com/product-detail/en/jst-sales-america-inc/SXH-001T-P0.6/455-1135-1-ND/527370 the contacts
04:49 PM CaptHindsight: heh $500-1000 for their crimper
04:50 PM CaptHindsight: I wonder how much the official wire stripper goes for?
04:51 PM CaptHindsight: and if you get a JST baseball cap with every purchase over $1k
04:52 PM roycroft: good crimp tools are usually pretty expensive
04:52 PM roycroft: but $500-$1k seems like an awful lot of money
04:53 PM roycroft: $350 seems more like what a tool like that should cost
04:55 PM jdh: $19.95
04:59 PM CaptHindsight: i never knew that their US HQ is nearby
05:00 PM CaptHindsight: http://www.jst.com/home19.html
05:02 PM CaptHindsight: maybe they make the crimpers in japan
06:54 PM gene83: CaptHindsight: nah, china. I've bought some that Amp would sell for $200, from China for less than $30. Work great.
09:42 PM * evilroot is toying with the idea of making the doors in his office open Star Trek style
09:46 PM djdelorie: you mean hiring two people to pull ropes when you get near it?
09:50 PM evilroot: "Hire"
09:51 PM evilroot: But no, I have these really cool pneumatic linear actuators and can't think of what to do with them
10:19 PM MrTrick: evilroot: articulated wings?
10:21 PM jdh: pull open the trap door that drops your guest/enemy into the lava or shark tank
10:22 PM MrTrick: "What?" / "Hold on a sec, I need to charge the compressor. Do NOT move!"
10:33 PM CaptHindsight: how about something practical like a dog polisher?
10:39 PM evilroot: lol
10:39 PM evilroot: They're 1400mm and accurate to 1mm supposedly
10:39 PM evilroot: Very fast and smooth but not particularly strong
10:40 PM evilroot: Was also thinking about maybe a painting rig
10:54 PM Wolf__: evilroot: need painter parts :P https://i.imgur.com/Gz2OHhl.jpg
11:24 PM nullifier: *wave*
11:25 PM nullifier: Anyone here familiar with Sanyo servo amps?
11:52 PM evilroot: Sanyo no, servo amps in general yes
11:52 PM evilroot: Why?
11:52 PM Wolf__: feed it power and signal and things spin
11:57 PM evilroot: That;s an oversimplification
11:57 PM Wolf__: just a little =)
