01:15 AM Wolf__: i’m cooked, was nasty out here today and I was stuck working outside from 10am till about 11:30pm
01:18 AM Wolf__: truck I was working on said 102, and thats not counting the heat index
01:52 AM Deejay: moin
02:08 AM fragalot: hey
02:20 AM CaptHindsight: yo
02:39 AM fragalot: gloops: because you asked a while ago: it seems that fusion360 *CAN* do full 5-axis
02:39 AM fragalot: true 5-axis*
02:45 AM miss0r: goodmorning(ish)
02:46 AM miss0r: :o gloopsis here
02:47 AM fragalot: mornin miss0r
02:48 AM miss0r: goodmorning. What are we up to today?
02:52 AM miss0r: I'm thinking I should do some hard milling today. (only here for a few hours anyway). I need to make some tooling for a special cutter
02:56 AM fragalot: miss0r: going out to pick up plumbing supplies, I mean, machine skates
02:57 AM miss0r: same difference ;)
02:57 AM fragalot: then build a small ramp to clear the step into my shed
02:57 AM fragalot: (with small, I mean as long as possible :P)
02:57 AM fragalot: which is, given where it's going, still quite small.
02:57 AM miss0r: yeah :)
02:57 AM fragalot: but it's only a 10cm step, so .. eh.
02:57 AM miss0r: I have the same issue here
02:58 AM miss0r: well, not the exact same issue
02:58 AM fragalot: of course you don't, with your fancy shed that's OVER TWICE THE SIZE of mine
02:58 AM miss0r: I bought a set of those ramps for car transport trailers. and made a bracket so I can snap'em on the entrance
02:58 AM fragalot: I bet you even have a large door opening :P
02:58 AM fragalot: that works
02:58 AM miss0r: the door is 80cm
02:59 AM fragalot: I was going to go cheap & make beech ramps with a 2mm sheet metal plate on top
02:59 AM miss0r: (custom made by my old boss retired carpenter father)
02:59 AM miss0r: good idea
03:00 AM miss0r: a shitty wooden door, actualy. it moves alot in the humid weather... in the dry summer, you have to use the lock to keep it closed when it is in its dry state.
03:00 AM miss0r: when it is very humid, it binds
03:00 AM Wolf__: thing too heavy to move, just get someone else to lift it like https://i.imgur.com/bheULL5.jpg
03:00 AM miss0r: :-/
03:00 AM fragalot: hehe
03:01 AM fragalot: Wolf__: what happened to the hole idea?
03:01 AM Wolf__: would need to clean all the dirt off after
03:01 AM syyl_: hm
03:01 AM Wolf__: too much work
03:01 AM fragalot: :P
03:01 AM syyl_: yay?
03:01 AM syyl_: seems to work finaly
03:01 AM fragalot: syyl_: I sold my RF45... in like, half an hour ._.
03:01 AM syyl_: i heard about that
03:01 AM Wolf__: crane said that thing was 11,00lbs
03:02 AM syyl_: finaly got round to register my nick on freenode ;)
03:02 AM fragalot: lol
03:02 AM fragalot: make sure to link an alternative
03:02 AM syyl_: thats why i never answered :D
03:02 AM miss0r: fragalot: Rent a crane. have it lift the roof off your shed and lower the mill in, and put the roof back on :]
03:02 AM fragalot: oh yeah.. I forgot I had PM's disabled from unregistered nicks :D
03:03 AM fragalot: miss0r: cranes that size can't get 'round the back.. so they would need to span OVER the house, and reach about 40m
03:03 AM miss0r: Whats your point?
03:03 AM Wolf__: $600 for 1.5hrs
03:03 AM fragalot: miss0r: big mofo of a crane
03:03 AM miss0r: still waiting for the punchline
03:04 AM Wolf__: if they drop it from high enough they wont need to take the roof off
03:04 AM fragalot: Wolf__: I think, knowing how the shed is constructed, you could just place it on top gently & get the same effect
03:04 AM Wolf__: lol
03:04 AM miss0r: lol
03:06 AM gloops: .
03:06 AM miss0r: gloops! you've been gone a long time ;)
03:06 AM gloops: wow, finally freenode snailmail gets my registration link to me!
03:06 AM fragalot: I wonder how many others have just been quiet because of this, lol
03:06 AM gloops: must be a few weeks miss0r yes
03:07 AM Wolf__: slackers
03:08 AM fragalot: christ I've apparently registered my nick (12y 31w 4d ago)
03:08 AM miss0r: damn
03:08 AM miss0r: how to tell?
03:08 AM fragalot: msg nickserv info
03:09 AM miss0r: I'm a mere rookie compared to you; 8y 34w 6d ago
03:09 AM miss0r: I win on two out'a three... so I win? :O
03:09 AM fragalot: lol
03:10 AM Wolf__: mines not that old
03:10 AM miss0r: I used to be on quakenet. That one must be old(assuming it still exists, which I realy doubt it does)
03:10 AM fragalot: probably does
03:10 AM fragalot: I never registered there
03:10 AM Wolf__: 4y 32w 3d
03:11 AM miss0r: Wolf__: You should only speak when spoken to, young one!
03:11 AM miss0r: :P
03:11 AM Wolf__: I use to use undernet back in ’94…
03:11 AM gloops: well i wont be reading the back logs anyway lol
03:11 AM * miss0r sets up a connection with quakenet to see if he is still registered
03:11 AM fragalot: (PS. you can request info on others too)
03:12 AM Wolf__: this was the overkill for the day https://i.imgur.com/6L21A0N.jpg 30ton crane
03:12 AM miss0r: I'm glad I didn't make up a crazy number then
03:12 AM fragalot: Wolf__: that number goes down quick if they need to reach out though :P
03:13 AM fragalot: like that 720ton crane I linked to
03:13 AM Wolf__: yeah
03:13 AM fragalot: anyway - i'm off to the shops
03:13 AM fragalot: cy
03:13 AM fragalot: a
03:13 AM miss0r: meh. I can't even remember what the quakenet equivalent of nickserv is
03:13 AM miss0r: good trip
03:13 AM Wolf__: but seeing we only needed to go up like a meter…
03:15 AM Wolf__: oh well, sleep then more truck works… then wait for more crap that needs to go on that garbage truck, then another one to do, or I think we have like 6 more lined up to install
03:15 AM miss0r: heh. quakenet member since '98
03:16 AM Wolf__: lol
03:16 AM miss0r: and quakenet was my first experience with IRC.
03:18 AM Wolf__: the old days of ping flooding the dial up users off line
03:18 AM miss0r: :]
03:21 AM miss0r: I'm glad I found thise place. The only thing I wouldn't mind finding still, was a proper machinist channel. I know theres alot of machinists in here, but the vast majority are here only for linuxcnc
03:21 AM Wolf__: oh yeah, sleep, need sleep, damn work…
03:21 AM miss0r: Have a good one ;)
03:21 AM Wolf__: facebook has a few good ones
03:22 AM * miss0r is not on there
03:22 AM Wolf__: youtube machinists group on there is somewhat active
03:23 AM miss0r: I guess my company should make a facebook profile at some point
03:25 AM Wolf__: a good machinist channel would be nice…
03:25 AM miss0r: Wolf__: Go sleep! :)
03:26 AM Wolf__: still have wiring schematics flying around my head
03:27 AM miss0r: :D I know the feeling
03:29 AM Wolf__: didn’t help that install directions had stuff like “BUTT SPLICE TO PIN 5 WIRE FROM THE BLACK PLUG ON ENGINE”...
03:29 AM Wolf__: not helpful
03:30 AM miss0r: I'm sure that means something
03:30 AM Wolf__: 10+ black plugs on the engine
03:30 AM * miss0r graps the engrish dictionary
03:30 AM miss0r: No visual aides?
03:30 AM Wolf__: nope lol
03:31 AM miss0r: did you try cleaning it ? :D
03:31 AM Wolf__: lol no, truck is new thank god
03:32 AM miss0r: damn them. they figured they could same a few cents replacing all the coloured ones with all black
03:32 AM Wolf__: real directions would state what the plug is connected to, how many pins…
03:33 AM Wolf__: but, nope
03:33 AM miss0r: you mush have some idea what 'signals' you are looking for. That could be of some help
03:34 AM Wolf__: somewhat, its a neg signal wire for idle up
03:36 AM Wolf__: deisel mechanic I am not
03:36 AM miss0r: idle up must be connected to the computer
03:36 AM miss0r: the one handeling the injection
03:37 AM miss0r: so, not on the engine itself, more likely a box near it
03:37 AM Wolf__: thats my guess, but 2x 80 pin in to the ECM on the side of the motor, I’m not going to randomly start splicing stuff
03:37 AM miss0r: I'm sure if you did a google search for that unit and idle up, you'd find something
03:38 AM Wolf__: guy I work with tried that, no luck
03:40 AM miss0r: damn
03:40 AM miss0r: Sounds like you need to go spend money getting what ever you are playing with hooked up then
03:41 AM Wolf__: ha, proper search terms help, bodybuilder manual
03:41 AM miss0r: ahh indeed
05:02 AM miss0r: I have here in front of me two tapmatic tapping heads, one is a model 1A, the other is an X50. I bought the both of them for ~134eur total. which I think is a damn fine price. But they are not complete. The X50 has no collects and the captive nut is missing. The 1A has the captive nut and one collect in there.
05:03 AM miss0r: Would any of you guys know how to get about getting new collects for these? the nut I should be able to machine without too much trouble
05:07 AM SpeedEvil: Is 'collect' an actual term, or an autocorrect of collet.
05:09 AM miss0r: if by autocorrect you mean, me thinking that was the name all along, then; yes - autocorrect
05:09 AM miss0r: :)
05:10 AM SpeedEvil: :)
05:10 AM SpeedEvil: Collets seem annoyingly fun to machine in most cases.
05:11 AM miss0r: well, if i'm to stick to the original design, its going to be fore annoying than fun. The original design calls for 4, 6 or 8 small steel wedges held together with rubber
05:11 AM miss0r: more*
05:11 AM SpeedEvil: https://www.youtube.com/watch?v=AEsaSN4LLU4 - sort of related
05:11 AM SpeedEvil: MAKING AND USING LARGE DIAMETER LAPS
05:13 AM miss0r: You gotta love that guy
05:14 AM SpeedEvil: miss0r: I assume tapmatic doesn't have spares?
05:14 AM miss0r: From what I can read, you have to send the unit in for repair to get spares :)
05:15 AM SpeedEvil: At rather more than $134 for two, I guess.
05:15 AM miss0r: that would be my guess
05:15 AM miss0r: They are not big on writing their pricing anywhere
05:15 AM miss0r: which usualy means expensive, in my experience
05:28 AM diep: Good Morning. In Stepconf i can move each axis. If i start AXIS after that with the created profile - i have no manual control seemingly. Doesn't even show it's connected. What can i try?
05:49 AM gloops: are the interface controls active diep? or greyed out
05:49 AM diep: good question - taking look
05:50 AM diep: started program again - AXIS
05:50 AM diep: manual control F3 it says
05:50 AM diep: underneath it everything is grey
05:50 AM gloops: http://bues.ch/images/awlsim-linuxcnc.png
05:50 AM gloops: top image, hit the X at the top left then the button to the right of it
05:51 AM diep: you mean underneath the manual control?
05:51 AM diep: that's grey here
05:52 AM gloops: no the red square with the X
05:52 AM gloops: red circle
05:52 AM diep: ok trying
05:52 AM diep: nothing happens if i click on the red X
05:53 AM gloops: ok, just to clarify, you have run stepconfig, that makes a profile - you have found that profile and run it?
05:53 AM diep: yes
05:53 AM diep: i made a profile
05:54 AM diep: and inside the stepconf i could move all 3 axis
05:54 AM diep: then i saved it
05:54 AM diep: and i clicked on the launch button now
05:54 AM diep: then get automatically in the program AXIS
05:55 AM diep: is it possible i specified the X Y Z axis correct but something else i didn't do?
05:55 AM diep: which AXIS expects?
05:55 AM gloops: no it shouldnt be greyed out, did you click the button at the side of the red X?
05:55 AM diep: i clicked on the X nothing happens
05:55 AM gloops: if there was an error in the profile it wouldnt load
05:56 AM diep: as if it can't communicate to the CNC box
05:56 AM gloops: and the button at the side of the X?
05:56 AM diep: oh i must first load a profile in AXIS?
05:56 AM gloops: i havent got linuxcnc on this PC so working from distant memory load
05:56 AM gloops: lol
05:56 AM jthornton: diep can you jog an axis?
05:57 AM diep: in stepconf i can
05:57 AM diep: but not in AXIS jthornton
05:57 AM jthornton: does the tool on the screen move when you try to jog in Axis?
05:57 AM diep: and the manual control is grey
05:57 AM gloops: the button at the side of the X is start
05:57 AM diep: yes that one i can't click
05:58 AM gloops: you need to activate the controls
05:58 AM diep: how do i activate the controls?
05:58 AM gloops: im thinking you have got an emergency stop switch open
05:58 AM jthornton: starting at the top left the estop must be off F1 toggles it
05:59 AM jthornton: then the power must be on and F2 toggles that
05:59 AM diep: the red X seems pushed in
05:59 AM diep: if i click F1 that doesn't change
05:59 AM jthornton: then the manual control tab should be active
05:59 AM diep: yes it is
05:59 AM diep: but all grey
06:00 AM diep: maybe in stepconf i didn't define something?
06:00 AM diep: i only defined XYZ and port 1
06:00 AM diep: if you hit X what does it ship to the machine?
06:00 AM jthornton: post a screen shot of Axis on imagebin.ca
06:00 AM diep: can i email it?
06:01 AM diep: let me make a picture
06:01 AM jthornton: I don't have email in the beer cave
06:02 AM diep: got the picture - transferring it to an internet box now here
06:02 AM gloops: the button at the side of the rec circle with X - play with those 2 buttons
06:03 AM jthornton: is is kind of confusing the estop must be off and the power must be on
06:04 AM diep: well i can move axis in stepconf
06:04 AM diep: when defining or modifying the profile
06:04 AM diep: but not in AXIS
06:05 AM gloops: just find the config on the desktop and open it from there
06:05 AM diep: i did
06:05 AM diep: then it opens axis
06:05 AM gloops: right
06:06 AM diep: button called: "launch 3040'
06:06 AM gloops: and played with those 2 buttons mentioned and the controls dont light up
06:06 AM jthornton: https://imagebin.ca/v/4Cbsjmitv51i
06:06 AM diep: if i click the X button nothing happens
06:06 AM jthornton: the estop and power buttons need to look like that
06:06 AM diep: what does it ship to the CNC if i click it?
06:07 AM jthornton: did you define an external estop in stepconf?
06:07 AM diep: i didn't
06:07 AM gloops: diep do you have an emergency stop switch?
06:07 AM gloops: on the machine?
06:07 AM diep: yes that blue box has a red button
06:07 AM diep: i didn't define the miilling motor either
06:07 AM gloops: anywa got to go to IKEA with the mrs...disgusting waste of time
06:07 AM diep: as the blue box i can select analogue how many rpm the DC motor makes
06:08 AM diep: good luck at IKEA
06:08 AM jthornton: can you post your hal file to https://paste.ubuntu.com/
06:08 AM diep: hal file?
06:08 AM diep: let me locate a *.hal on da box
06:08 AM diep: i'm bit command line linux still
06:09 AM jthornton: linuxcnc/configs
06:11 AM diep: ah give me a few minutes - first must connect from that box to the internal TLS server
06:11 AM diep: to upload that file
06:11 AM diep: didn't configure networking yet
06:11 AM diep: found the hal file
06:11 AM diep: 3040.hal
06:35 AM diep: oh la la lots of dependencies just to install filezilla :)
06:35 AM diep: and harddrive of this old box too small to hold all wheezy files
06:42 AM jthornton: in your main hal file see if you have a line similar to this
06:42 AM jthornton: net estop-loop iocontrol.0.user-enable-out => iocontrol.0.emc-enable-in
06:54 AM diep: nearly there - filezilla works :)
06:54 AM diep: the 512MB ram in the old box seems a limit though
06:57 AM diep: and of course if you say so then the network doesn't work as it should :)
06:57 AM diep: let me find the net estop-loop
06:58 AM diep: no such line in the hal file
06:58 AM diep: there is net estop-out and net estop-ext
06:59 AM diep: let me add this line to the file
06:59 AM diep: and see the result...
06:59 AM jthornton: yea estop will not work without that line
07:00 AM diep: doh emacs not working
07:00 AM diep: let me find another one as vi i can't remember what it was
07:01 AM jthornton: nano
07:01 AM jthornton: or pluma
07:01 AM diep: yup
07:01 AM diep: mousepad it seems is default nowadays in debian
07:04 AM diep: i saved it into the hal file
07:04 AM diep: then i clicked on launch 3040
07:05 AM diep: and it doesn't start - instead i get a LinuxCNC Errors
07:05 AM jthornton: need the specific error
07:06 AM diep: i guess you looking for this one
07:06 AM diep: debug file information:
07:07 AM jthornton: did LinuxCNC toss up an error screen?
07:07 AM diep: ./3040.hal:84: Pin 'iocontrol.0.user-enable-out was already linked to signal 'estop-out'
07:07 AM jthornton: usually the error is in there
07:07 AM diep: 5304
07:07 AM jthornton: yes
07:07 AM diep: yes error screen
07:07 AM diep: i can make a photo if it helps
07:08 AM diep: somehow the network light is not blinking so no network until i probably modified firewall of linuxcnc
07:08 AM jthornton: comment out that line you added and look for iocontrol.0.user-enable-out
07:08 AM diep: yes the hal file has just above that line i added:
07:09 AM diep: net estop-out <= iocontrol.0.user-enable-out
07:09 AM diep: net estop-ext => iocontrol.0.emc-enable-in
07:09 AM diep: oh wait let me find iocontrol.0
07:10 AM jthornton: that is correct then
07:10 AM jthornton: well no
07:10 AM jthornton: ext suggests an external estop is configured
07:11 AM diep: i can modify that in the stepconf wizard?
07:12 AM jthornton: yes look at the inputs and see if you have estop configured
07:12 AM diep: i had followed this crashcourse linuxcnc configuring : https://www.youtube.com/watch?v=X2AN654CExw
07:12 AM diep: ok let me open the wizard
07:14 AM diep: drivertype i had not filled in
07:14 AM diep: should put 'sherline' there?
07:14 AM diep: aha it says there pin 10: estop in
07:15 AM diep: though i'm 100% sure i had put it all at unused
07:15 AM diep: also it suddenly has A axis
07:15 AM jthornton: no you don't need driver type just the timings
07:15 AM jthornton: that is a stupid default
07:15 AM diep: i had removed that default
07:15 AM jthornton: as well as the estop is a stupid default
07:15 AM diep: pin 1 : estop out is correct?
07:15 AM diep: or should i only define X Y Z and nothing else?
07:16 AM diep: step + dir for each axis
07:16 AM jthornton: no should be none unless you have an external estop wired to pin 1
07:16 AM jthornton: yea only define what you have
07:16 AM diep: it's all at unused now
07:16 AM jthornton: that is correct
07:16 AM jthornton: dumb defaults
07:17 AM diep: saved and quit
07:17 AM diep: let me reopen the wizard again to check it's unused all now
07:18 AM diep: is it possible that if you close the wizard with X on the right top - that it still saves that file using defaults and not leave it unchanged?
07:19 AM diep: let's launch it again :)
07:20 AM diep: cool now i can click the red X and the next button to start machine again
07:20 AM diep: YES manual works now
07:20 AM diep: thanks (y)
07:24 AM jthornton: no problem
07:24 AM * jthornton goes to pick up chicken poop
07:25 AM diep: how many have you got?
07:27 AM diep: back to getting the axis at 90 degrees or parallel trammed...
07:42 AM jthornton: 9 Rhode Island Red hens
07:55 AM fragalot: hi
07:57 AM jthornton: hey
08:02 AM jthornton: diep: the best place to look for information about LinuxCNC is the documents
08:15 AM Tom_L: 68F Hi 89
08:19 AM jthornton: same here
08:34 AM jthornton: dang I'm stumped why I get a following error on one config but not another that is the same
08:36 AM Tom_L: did you do a file compare on them?
08:37 AM jthornton: no
08:38 AM jthornton: with all this rain we have been getting I might have to mow the grass for the third time this year
08:38 AM Tom_L: kid mowed yesterday and i edged when i got home
08:39 AM Tom_L: been a rather wet August
08:41 AM jthornton: yea and I've been wanting to build up some low spots in the chicken yard but my dirt pile is too wet
08:41 AM Tom_L: mowing may help the varmint issues you have
08:41 AM jthornton: hows that?
08:42 AM Tom_L: or does that just provide a clearing for them to attack?
08:42 AM Tom_L: i figured they like to hide in the tall grass
08:42 AM Tom_L: or does it not get that tall
08:43 AM jthornton: no tall grass, are you talking about the squirrels?
08:45 AM Tom_L: i was thinking coons etc
08:45 AM jthornton: ah the coons come out at night
08:47 AM Tom_L: i've seen more possums and armadillo here lately
08:53 AM * jthornton gives up for now smelling bacon time for chow
09:11 AM gloops: get it working diep ?
09:12 AM jthornton: yea he did
09:13 AM gloops: excellent
09:14 AM gloops: ill never go to Ikea again
09:14 AM Tom_L: why?
09:14 AM gloops: terrible
09:15 AM gloops: massive building, layout like a maze
09:15 AM gloops: mostly crap
09:16 AM Tom_L: i've heard they are big
09:16 AM gloops: well shopping isnt my thing anyway lol
09:17 AM Tom_L: not unless it's machine tools
09:17 AM gloops: yes
09:17 AM Tom_L: even then i know what i'm going for. this brousing crap is for the birds
09:19 AM gloops: wouldnt have been so bad if it was laid out in aisles, with like kitchen on one aisle, bedroom on another etc, so you could go to the place you wanted - you have to walk all round the maze to get to something
09:19 AM gloops: anyway bbl
09:29 AM jthornton: narrowed it down to something bonkers in the ini file
09:40 AM fragalot: gloops: theydo have shortcuts to everywhere...
09:42 AM pcw_home: I went to a local IKEA _once_, you are herded like cattle through the store, never again...
09:44 AM tiwake: pcw_home: never been herded before in such a store
09:46 AM pcw_home: My one experience was so bad I will never go back
10:34 AM jesseg: pcw_home, who was herding you?
10:39 AM hazzy-lab: pcw_home: I have had the same experience. And they have this predefined (but unmarked) path that you have to follow, and if you dare to walk back to look at something they act as if you are breaking some law.
10:40 AM jesseg: you mean like the employees follow you around as you shop? lol that's hilarious!
10:40 AM jesseg: in a disgusting kind of way :P
10:41 AM jesseg: I haven't been to an ikea in over a decade I suppose
10:41 AM jesseg: sounds like they've changed tactics
10:42 AM hazzy-lab: jesseg: they don't really follow you around, herding is about right though
10:43 AM hazzy-lab: I can't stand being in any store where there is not a direct line of sight exit either, and they intentionally make it very hard to find how to get out
10:44 AM jesseg: I always thought they were a tad odd
10:44 AM hazzy-lab: I believe there it a horror type video game based off of being stuck in an ikea store, lol
10:44 AM jesseg: LOL
10:45 AM hazzy-lab: https://venturebeat.com/2017/12/08/scp-3008-is-survival-horror-in-an-unending-ikea-purgatory/
10:45 AM hazzy-lab: hehe
10:45 AM hazzy-lab: about right
10:55 AM gloops: what do you do if theres a fire? i had no idea where in the building i was at any time
11:05 AM jthornton: figured out that using imperial units in the ini actually gives you mm so the jog rate was so high it had a following error...
11:07 AM pcw_home: Also the pid maxerror thing that pncconf does should either be dropped or scale appropriately for inch/metric systems
11:08 AM pcw_home: s/scaled/scale/
11:10 AM jthornton: what is that?
11:19 AM jthornton: I need to fix my PID default values I think to account for units
11:27 AM sync: hazzy-lab pcw_home I never had that experience in an ikea
11:27 AM sync: I mean, yeah they are making you walk through the store but, the shortcuts are on the map
11:28 AM sync: so you can get through it quite fast
11:29 AM diep: thanks for asking gloops (16:04) - yes i can manual control the 3 axis now. can fix the machine now, tram it and then add the endstops. don't want to mill without adding endstops - if the electronics allow it :)
11:29 AM diep: Y-axis is 0.06mm error now which is good and the theoretic expected on a crabble note here
11:30 AM diep: axis is 8+ kilo say 85N. If we have distributed load on 2 simple 16mm axis i would expect distributed load 70% of that roughly = 60N roughly
11:30 AM diep: deflection (mm) = P * L ^ 3 / ( I E Y )
11:31 AM diep: 60N 518^3 / (210k 192 * Iyy)
11:31 AM diep: yy = pi * 16^4 / 64 = 3217
11:31 AM diep: deflection ( mm ) = 0.064mm
11:31 AM diep: and i measured 60microns
11:31 AM diep: seems ok - now the X-axis :)
11:33 AM jthornton: pcw_home: if you get a chance see if the number are ok for the joint for a 7i96 https://paste.ubuntu.com/p/d5ms8HrFKs/
11:39 AM pcw_home: PID values will be the same for inch or metric
11:42 AM pcw_home: max error should either be deleted or scaled for metric on metric configs
12:05 PM Roguish: Tom_L: hey Tom, I purchased a stylus from cmms.com. stainless shaft, ruby sphere. free USPS shipping...... should have it early next week.
02:13 PM FAalbers: Hello. Can you guys recommend me a good tutorial explaining the workflow of designing on Fusion360 and then cutting it in linuxcnc ?
02:14 PM FAalbers: there are so many videos where they show the design and then the mill cutting , but with explanation on how to.Just that it works.
02:14 PM FAalbers: Thanks
02:21 PM miss0r: fragalot: I just finished the bulk of the filing, taking a cheap reciprocating saw, and machining some files to fit init :)
02:22 PM Rab: I've often thought about an electric reciprocating file, I don't know why it's not a common product.
02:22 PM Rab: Or maybe it is and I'm just oblivious.
02:23 PM Rab: I guess those tiny handheld belt sanders are more effective.
02:23 PM miss0r: you can get some
02:24 PM miss0r: but I don't often need one, and my neighboor just threw one out, because it couldn't go realy fast no more.. So perfect for filing :)
02:24 PM Rab: Hmm: https://www.reciprotools.com/
02:26 PM diep: the odour coming from that 3040 is as if inside something is getting soldered with lead
02:27 PM Rab: diep, could be the drivers or steppers are getting hot.
02:27 PM diep: yet the box is idle :)
02:28 PM pcw_home: Step motors typically get hottest when idle (unless they have automatic power down)
02:28 PM diep: time to break the seal and open that box and see what is inside :)
02:28 PM diep: X and Y motor: cold, Z motor like 25C
02:29 PM diep: turned on airco to get rid of the odour
02:29 PM miss0r: :D
02:29 PM miss0r: I had a 3040 once. Pure chinesium.
02:29 PM Rab: That'll just disperse the carginogens throughout your family dwelling.
02:29 PM miss0r: the smell you are referring to is 'chinesium stank'
02:30 PM diep: i've got a room filled with machines all oiled
02:30 PM diep: and this ain't an oil odour
02:30 PM diep: if i add endstops, assuming the electronics will eat it that's inside the box
02:30 PM diep: does the linuxCNC work same way with endstops like 3d printers usually do?
02:31 PM XXCoder: in what way?
02:31 PM diep: as i see some chinese hack to add endstops, to save out a few wires where they inversed the logics it seems
02:31 PM diep: it gives a signal there when it gets pushed
02:31 PM XXCoder: linuxcnc you can build it in whatever.
02:31 PM diep: instead of not giving a signal when pushed
02:31 PM XXCoder: I suggest normally high, so wire breaks stops machine and not fail to stop
02:32 PM Rab: diep, that is not ideal.
02:32 PM diep: yes - i guess that the chinese inventive way of saving another handful of pennies blindfolded them again there
02:32 PM diep: this machine has no endstops
02:32 PM miss0r: hmm.. what you need them for anyway?
02:33 PM diep: i need them because i know myself :)
02:33 PM XXCoder: miss0r: me for one wants homing stops so I have repeatable homing
02:33 PM miss0r: acme screws & steppers on there is not realy powerfull enough to pull it apart anyway
02:33 PM miss0r: XXCoder: Repeatable homing with microswitches? :D
02:33 PM XXCoder: far more repeatable than by hand
02:33 PM diep: that's another reason miss0r
02:33 PM miss0r: at best that is within a few 1/100s
02:33 PM XXCoder: also, who said im using microswitches lol
02:34 PM miss0r: XXCoder: Fair enough, that was unrightfully assumed
02:34 PM XXCoder: oh yeah diep dont use reprap design of smashing into switches. design it properly
02:34 PM diep: the ones i bought, just 12 cents a piece, they do surprising well there miss0r
02:34 PM diep: i have my own commercial 3d printer line of printers XXCoder - soon to hit the market i hope
02:34 PM miss0r: diep: Yeah, but when it comes to repeatability they are not 'that' acurate
02:34 PM XXCoder: cool can I have a sample machine? ;)
02:34 PM diep: but yeah i also started with a reprip
02:35 PM diep: have a website and making much noise around?
02:35 PM diep: like sexycyborg ;)
02:35 PM XXCoder: nah. drat lol
02:35 PM diep: though i doubt i ship one off to china for that purpose :)
02:35 PM diep: seems you need to do that if you're in the $400 range
02:35 PM diep: as then other sort of feelings make people decide to hit that "buy it now" button :)
02:36 PM miss0r: meh. I'll call it a night. See you around
02:36 PM * miss0r is off
02:36 PM XXCoder: later
02:36 PM XXCoder: diep: fili printer using linuxcnc?
02:36 PM diep: printer is not using that of course
02:37 PM FAalbers: Anyone using Fusion 360 here ?
02:37 PM diep: freecad + turbocad here
02:38 PM diep: fusion360 is online design isn't it? Free for anyone to take a look at what you design - maybe good plan for open source hardware?
02:38 PM XXCoder: drat hoped for nice linuxcnc mods to make it work with printer
02:38 PM FAalbers: yes , free for hobbiests
02:38 PM XXCoder: I dont really like reprap firmwares. theyre all unsafe
02:38 PM diep: oh i know someone who is using linuxcnc just for that
02:38 PM diep: for his 3d printer
02:40 PM XXCoder: cool
02:42 PM diep: linuxcnc moves motors much better than most firmware for 3d printers. yet getting it to work is the problem
02:42 PM CaptHindsight: diep: I use it for all of mine
02:42 PM CaptHindsight: FDM, SLA, SLS, etc
02:43 PM CaptHindsight: we even synthesize DNA with printers controlled by LCNC
02:43 PM * fragalot just spent the entire afternoon mucking out his shed
02:43 PM fragalot: got rid of like 2m³ worth of stuff, and you still can't tell >.<
02:43 PM CaptHindsight: also robots that amplify DNA, apply DNA etc
02:44 PM CaptHindsight: fragalot: yeah it all adds up
02:44 PM KleinerMann is now known as Guest16652
02:44 PM CaptHindsight: fragalot: did you figure out how to shrink the machine by 10cm or narrow the walkway?
02:45 PM CaptHindsight: widen, not narrow
02:45 PM fragalot: narrowing the walkway is the easy part
02:45 PM fragalot: lol
02:45 PM CaptHindsight: heh
02:45 PM CaptHindsight: was talking to Biologists so forgive me
02:45 PM fragalot: I did build a small ramp
02:46 PM fragalot: but all that does is get my hopes up that i'll get it to that point :P
02:46 PM CaptHindsight: what I have pictured in my head https://i.ytimg.com/vi/XNYpV7wtGJ8/hqdefault.jpg
02:47 PM diep: one reason to also use endstops is because i want the full milling range of the router
02:47 PM diep: easy to make a mistake then
02:47 PM fragalot: CaptHindsight: hur :D
02:48 PM diep: can take a few more risks with the 3040 that i wouldn't take for the other build i have
02:49 PM CaptHindsight: diep: is your 305\40 similar? https://postimg.cc/image/jwre6apxz/
02:49 PM CaptHindsight: 3040
02:52 PM diep: not at all CaptHindsight
02:52 PM diep: that seems a stronger build than this one
02:52 PM diep: it seems every few years they have more optimizations to do it cheaper those 3040s
02:52 PM XXCoder: mines just a little bit later version
02:52 PM diep: this one was 560 dollar on ebay, about 504 euro
02:52 PM fragalot: 'optimizations'
02:53 PM XXCoder: if I recall your machines sides was custonm correct?
02:53 PM XXCoder: more offset to back
02:53 PM diep: i bought this one: https://www.ebay.com/itm/3-Axis-3040-CNC-Router-Engraver-Milling-Engraving-Drilling-Desktop-Machine-400W/292660662535?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
02:54 PM XXCoder: my machine https://www.youtube.com/watch?v=1JMSRF6Q9uw
02:54 PM XXCoder: yep they removed front cover for cheaper price diep
02:55 PM diep: and the end stops already for a few years
02:55 PM CaptHindsight: heh, they keep shaving off corners
02:55 PM diep: didn't realize that when i bought it
02:55 PM CaptHindsight: soon they will be made from paper
02:55 PM XXCoder: also, screws not ballscrews
02:55 PM fragalot: CaptHindsight: actually they stop shaving corners to save on labor
02:55 PM diep: paper is more expensive than recycling plastic :)
02:55 PM diep: the bridge weighs a whopping 8+ kilo
02:56 PM CaptHindsight: mystery metal/plastic frames , yeah thats probably next
02:56 PM XXCoder: already happened CaptHindsight
02:56 PM fragalot: die-cast frame :P
02:57 PM XXCoder: https://www.aliexpress.com/item/MOSKI-cnc-machine-cnc1310-metal-engraving-cutting-machine-mini-CNC-machine-cnc-router-pvc-pcb-aluminum/32837642599.html
02:57 PM XXCoder: oh wait thts all metal version. new to me
02:57 PM CaptHindsight: https://www.ebay.com/itm/Lead-Screw-T8X8-3D-Printer-450mm-picth-2mm-lead-8mm-Brass-Nut/122934803730 with <5mm of lash
02:58 PM diep: the MP CNC type designs are coming now
02:58 PM fragalot: CaptHindsight: you can compensate for that in sofrware
02:58 PM XXCoder: some plasics. very cheap tho lol https://www.aliexpress.com/item/CNC-3018-laser-options-with-ER11-diy-cnc-engraving-machine-Pcb-Milling-Machine-Wood-Carving-machine/32806004900.html
02:58 PM CaptHindsight: hobby motor spindle
02:58 PM diep: and for 3d printing in fact a pretty good design there considering the materials is the Ruzzian version 3d printer the Piper2
02:58 PM XXCoder: you can SEE table being not parallel to machine frame.
02:58 PM CaptHindsight: fragalot: if you keep the parts as models you save even more
02:59 PM diep: bridge here built good in factory - the frame however X axis at least a MM off
02:59 PM diep: gonna measure now how much i need to correct
02:59 PM diep: maybe doing endstops first
02:59 PM fragalot: my 'Sable 2015' cnc has a 1mm bow in the table
02:59 PM CaptHindsight: wow a 13 x 10 cm router
02:59 PM diep: how they manage to design that cheap is mystery to me
02:59 PM CaptHindsight: thats pre stressed
02:59 PM diep: the cnc milling machine i'm building
02:59 PM Rab: CaptHindsight, there are a few router frame kits made from PVC sheet. Buyer beware, on eBay it looks similar to aluminum plate.
03:00 PM diep: i sourced for at least 3000 euro worth of materials
03:00 PM diep: but will take many months to complete
03:00 PM fragalot: diep: probably helps if you're at the source of said materials
03:00 PM CaptHindsight: scrap yard
03:00 PM diep: yeah and also the knowledge they are gonna sell thousands
03:00 PM diep: as they know no one can beat 'em in price
03:00 PM CaptHindsight: and it cost too much to return
03:01 PM diep: i don't want to return it
03:01 PM diep: i'll fix it :)
03:01 PM diep: just the alu t-slot profile i can't buy that cheap
03:01 PM CaptHindsight: 5500mW, that like 5500000uW!
03:02 PM CaptHindsight: feel the power!
03:02 PM diep: chinese will show up with their MP-CNC variants from "metal"
03:02 PM diep: that are gonna be cheaper than the 3040s
03:02 PM fragalot: don't look into laser with remaining eye
03:02 PM CaptHindsight: Software GRBL control
03:02 PM CaptHindsight: serves them right
03:02 PM nallar is now known as Ross
03:04 PM CaptHindsight: https://hackaday.com/2013/10/17/unorthodox-home-made-cnc-machine/
03:04 PM CaptHindsight: a pipe dream
03:04 PM fragalot: just when you thought they couldn't get any worse, lol
03:04 PM XXCoder: MPCNC machines is bit silly also
03:05 PM CaptHindsight: the same that brought you https://hackaday.com/2018/05/05/printed-circuits-in-the-palm-of-your-hand/
03:05 PM CaptHindsight: the video is the back of his hand
03:05 PM CaptHindsight: I want to see him reflow that :)
03:05 PM diep: don't underestimate the MP CNC
03:05 PM diep: for stiffness over say a meter
03:06 PM diep: you need big diameter
03:06 PM diep: know a cheap way of doing that ?
03:06 PM XXCoder: scrap sewer pipes ;)
03:06 PM diep: the ripreps use 8mm smoothrods - that's ok for 200mm but more forget it
03:06 PM diep: yeah so they use conduit pipes :)
03:08 PM diep: someone will figure out a better way to run over them - the current 4 bearing 608zz solution for the MP CNC is a joke
03:08 PM XXCoder: 608zz is everywhere
03:08 PM XXCoder: even behind you
03:09 PM diep: even in my own 3d printer design it is :)
03:09 PM diep: they cost 8 dollar cent each buy in @ china
03:09 PM diep: in bit larger quantities
03:12 PM CaptHindsight: 8 dollar cent each?
03:13 PM CaptHindsight: 8 cents or each?
03:13 PM XXCoder: or per 100?
03:14 PM XXCoder: or per all 608zz in china at that time?
03:15 PM diep: let's not play language games - i'm not native English. dutch or Zherman however is easier there for 'perfektes' formulation
03:16 PM XXCoder: diep: actually you was being amgious. its not clear what you meant on pricing
03:16 PM diep: price drops to 8 dollar cent a piece buy in
03:17 PM diep: 0.08 dollar
03:17 PM XXCoder: ah was thinking 8 dollars and a cent
03:17 PM diep: whereas many interesting bearings are easily 1 or 2 dollar
03:17 PM diep: and no way to negotiate cheaper price
03:17 PM XXCoder: yeah market demends. 608zz so many stuff use that
03:18 PM XXCoder: well off later
03:18 PM diep: even if i would so to speak be very succesful man in life and sell thousands of printers - couple of thousands of bearings is peanuts to buy
03:18 PM diep: not a good negotiation point if you just buy a couple of thousands of bearings
03:19 PM CaptHindsight: ok so 8 cents , thanks
03:20 PM diep: i always am under impression with china there is 2 pricelists there. 1 for chinese 1 for foreigners
03:21 PM CaptHindsight: there is
03:24 PM CaptHindsight: Chinese price is always at least 10% less than to foreigners
03:24 PM diep: and alibaba is even more evil there - you get like 1 offer out of china and that's it. and the other offers 100% sure won't EVER be lower than that
03:24 PM diep: with a price just too high to even take serious
03:24 PM CaptHindsight: oh don't bother getting quotes through Alibobo
03:24 PM diep: right - i stopped that alltogether
03:24 PM diep: already years ago
03:24 PM CaptHindsight: talk direct
03:24 PM diep: yes - directly 3x lower price for filament rolls for example :)
03:24 PM diep: however you underestimate chinese government
03:24 PM diep: if you talk today to alibaba
03:24 PM diep: then if you approach manufacturers the next day
03:24 PM diep: they won't answer
03:24 PM diep: try them a year later
03:24 PM diep: they directly answer
03:24 PM diep: so it is very trivial and 100% sure for me the government has a kind of 'time window' that alibaba then gets exclusive rights
03:24 PM diep: and they just cutoff the rest
03:24 PM diep: to you
03:24 PM diep: don't ask a single question on alibaba and you get suddenly very competative prices
03:24 PM diep: ask 1 question and all other talks get kind of not through the chinese big firewall
03:25 PM diep: but i should fix a CNC machine here :)
03:38 PM CaptHindsight: there are Chinese sites dedicated to hardware but........
03:38 PM CaptHindsight: you need to be able to read/write Mandarin
03:43 PM diep: let's do some math here. over Z-axis reach of 20mm, the Z-axis is nearly 0.2mm not at 90 degrees to the bed
03:43 PM diep: in the Y-Z plane
03:46 PM diep: it's cool linuxcnc works - if i had to measure it without the electronics working - lot of work to turn those steppers around :)
03:46 PM diep: on youtube the leadscrews are 5mm each turn - but here they are 2mm
04:41 PM Deejay: gn8
08:34 PM nallar is now known as Ross
08:54 PM XXCoder: interesting https://www.youtube.com/watch?v=OrFG8X7w8yQ
10:38 PM hazzy-lab: XXCoder: it's robin, of course it is interesting! :D
10:39 PM XXCoder: lol
