02:44 AM Deejay: moin
04:59 AM jthornton: morning
05:00 AM XXCoder: yo
05:01 AM XXCoder: i ordered 1/4 inch spring holder and gage pin to act as tool :D
05:02 AM jthornton: for?
05:04 AM XXCoder: i bought a collet to show people in work event
05:04 AM XXCoder: event to talk about work life while deaf
05:04 AM XXCoder: for deaf kids to teenagers
05:06 AM XXCoder: its quite cheap I p[robably wouldnt trust it in actual cnc machine but for shoeing whatever
05:07 AM XXCoder: *showing
05:08 AM jthornton: cool
05:08 AM XXCoder: yeah
05:08 AM XXCoder: it looks surpising nice
05:08 AM XXCoder: no dents or rough
05:29 AM t4nk_freenode: XXCoder, is your hearing impaired too?
05:29 AM XXCoder: i dont own hearing impaired?
05:29 AM t4nk_freenode: ah, mentally, I see :)
05:30 AM XXCoder: you used your and call me mentally impaired lol
05:30 AM t4nk_freenode: ah, lol
05:30 AM t4nk_freenode: didn't notice that
05:30 AM XXCoder: well im deaf yes
05:30 AM t4nk_freenode: IT IS NOT LIKE ME, I can tell you :)
05:30 AM XXCoder: since birth
05:32 AM t4nk_freenode: didn't know that
05:33 AM t4nk_freenode: what's wrong with 'your' btw?
05:33 AM t4nk_freenode: coming to think of it
05:33 AM XXCoder: your is statement of ownership
05:33 AM XXCoder: you're is short of you are
05:33 AM t4nk_freenode: yes,
05:34 AM t4nk_freenode: so, what's wrong then
05:34 AM XXCoder: that sentance dont make sense with your
05:34 AM XXCoder: hence my teasing
05:34 AM t4nk_freenode: ?
05:34 AM t4nk_freenode: what should it have been then? 'is you are ...'?
05:34 AM XXCoder: or you're
05:35 AM XXCoder: if lazy youre works lol
05:35 AM t4nk_freenode: ? I am not a native speaker, but it isn't too hard to spot that it isn't quite right I'd say
05:35 AM XXCoder: yeah missing ' messes with it a little
05:36 AM t4nk_freenode: you're is a contraction of you are, tight?
05:36 AM t4nk_freenode: 'right'
05:36 AM XXCoder: yeah
05:36 AM t4nk_freenode: so I was talking about your hearing
05:36 AM t4nk_freenode: not you are hearing
05:36 AM t4nk_freenode: it's early in the morning for me though ;)
05:37 AM XXCoder: your statement would work with you
05:37 AM XXCoder: but you are are more peoper
05:37 AM XXCoder: proper
05:37 AM t4nk_freenode: you mean: "you're statement"
05:37 AM t4nk_freenode: :b
05:38 AM XXCoder: this would also work: "are you hearing impaired"
05:40 AM t4nk_freenode: if 'impaired' is a nickname for someone, then yes ;)
05:40 AM t4nk_freenode: but otherwise, it couldn't be farther off
05:40 AM XXCoder: whatever
05:41 AM t4nk_freenode: okidoki, 'your right' :b
08:41 AM taloot: hi guys. again, whats better driving servo in step/pulse @ 4mhz or in volicety mode 0-10v
08:45 AM jthornton: velocity always
08:45 AM taloot: what daughter board
08:45 AM taloot: i should use
08:46 AM taloot: 4 servo
09:09 AM Centreline: hi all, dumb question, but I cant seem to turn up anything on this, what is the name of the second probe if you have two porbes?
09:10 AM Centreline: I have a toolsetter and that's configured to be motion.probe-input but I want to add a touch probe for machine probing on a different pin
09:10 AM Centreline: Im probably not understanding something even having this question
09:12 AM jthornton: 7i77
09:12 AM jthornton: they both have to go to motion probe input you have to select the active one
09:13 AM Centreline: no its on a parport, I know the pin setup, but I'm using gmocappy so I dont have a clue how to select the active probe
09:13 AM Centreline: I can see both pins in halshow currently, just how to switch to do touchprobe instead of toolsetter
09:15 AM jthornton: not select sorry or them
09:16 AM Centreline: oh ok that makes sense
09:16 AM jthornton: probe 1 > or2.0.in0 probe 2 > or2.0.in1 or2.0.out > motion.probe.input
09:17 AM Centreline: thanks I figured theyd have a different signal name like motion.probe-toolsetter.input not share the same name
09:24 AM Loetmichel: re from work... all for nothing sitting 4.5 hours at work waiting for a cowoerker to finish his job so i can do what i was supposed to. nope, not happening. And for that i drive to the company on a sunday :-(
09:56 AM Centreline: jthornton, have that working n0ow thanks, I hadnt loaded the or2 component into the servo-thread
10:17 AM Loetmichel: re from the run for Döner... BAH what a weather (its raining cats and dogs) but: Drifting in a BMW 525i station wagon is fuuuuun ;)
11:11 AM jthornton: your welcome
11:15 AM Centreline: just pulled the suds pump from the machine trying to diagnose why there's this massive inrush current, and ho hum, I inherited a UK built bridgeport with a 110v suds pump. they are supposed to have all been 220vac
11:16 AM _unreal_: sigh
11:16 AM SpeedEvil: Centreline: :)
11:16 AM _unreal_: soooooo much room cleaning to do
11:16 AM SpeedEvil: Centreline: are the windings the original colour, or a charming brown?
11:17 AM Centreline: I havent ran it long, I just got estop events when it started occasionally so I've been trying to diagnose why
11:17 AM Centreline: I might have a 110v transformer spare somewhere
11:17 AM Centreline: If not, a 380v 3 phase suds pump and find a contactor anyway
11:18 AM Centreline: (I am in 380v 3 phase land)
11:48 AM pa: hello
11:48 AM pa: newbie question: does linuxcnc support usb connections to an arduino?
11:49 AM Tom_L: for what purpose?
11:49 AM Tom_L: typically no
11:49 AM Tom_L: for something like an mpg maybe
11:50 AM pa: Tom_L, so as i wrote, i'm anewbie. i just bought my first mill (a small proxxon mf70) and a CNC conversion kit
11:50 AM pa: that is supposedly 3 motors, plus an arduino
11:50 AM pa: with grbl on it afaict
11:50 AM Tom_L: yeah most likely
11:50 AM pa: but i was wondering if i could instead use linuxcnc
11:50 AM Tom_L: not with USB
11:51 AM pa: right
11:51 AM pa: thanks
11:51 AM pa: Tom_L, do you know if, for the setup i bought, there exists some sort of GUI software to send commands via usb to "manually control" the cnc converted mill?
11:52 AM pa: like to do simple things without having to go via cad->cam ?
11:52 AM pa: like simple straight cuts or so
11:52 AM Tom_L: no
11:52 AM pa: ok, thanks
11:57 AM jthornton: no need for cad or cam for simple G code a text editor does fine
11:58 AM pa: i read on their doc of fabulous GUIs people use
11:58 AM pa: but haven't fount any so far
11:59 AM pa: it's just that i have never used gcode, so a gui would be simpler and spare me from learning it :-)
11:59 AM Tom_L: doc was probably written by a marketing expert
11:59 AM Tom_L: you should learn it. it's not that difficult
12:03 PM pa: by the way, is there any good free-to-use (for private use) cam tool to be recommended?
12:04 PM syyl: no
12:04 PM syyl: or you consider fusion360 as free
12:05 PM pa: is it free?
12:05 PM pa: i have never used any CAD/CAM so i'm total blank :-)
12:06 PM pa: i was also looking for CAD/CAM 101s but couldnt find any
12:06 PM syyl: its free for personal/private use
12:06 PM syyl: with some very minor/irrelevant limitations
12:07 PM pa: ah interesting! thanks :-)
12:07 PM pa: basically what i would like to eventually mill is a washer with this profile
12:07 PM pa: https://imgur.com/a/00q10Zv
12:08 PM pa: of course my drawing is incorrect, since the profile is supposed to be radial
12:18 PM _unreal_: one of my latest FREEBE's I got from work
12:18 PM _unreal_: kbbc-24m
12:21 PM _unreal_: Damn wish it could take a digital speed control
12:23 PM Tom_L: i converted the one from my sherline
12:24 PM Tom_L: but it runs off of mains power
12:26 PM _unreal_: AC or dc?
12:26 PM Tom_L: dc out
12:26 PM _unreal_: oh looks like this can take 0-5v signal
12:26 PM Tom_L: ac in
12:26 PM _unreal_: or POT
12:26 PM _unreal_: for speed control
12:26 PM Tom_L: careful of floating ground on those
12:26 PM _unreal_: if I can do 0-5v I'll setup an arduino attiny
12:26 PM Tom_L: i had to add an isolation board on mine
12:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/PDF/
12:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/PDF/kbsi_240d_manual.pdf
12:28 PM Tom_L: you may not need that
12:28 PM _unreal_: Oh!!! and it supports upto 48v
12:31 PM _unreal_: Dc input power though for mine :( wish it was AC in
12:55 PM Loetmichel: harhar, note to self: 7 days of clothing is exactly 3/4 of a washing machine load and a full drying rack load. No problem there. I STILL should start doing laundry BEFORE i take out the last jeans, the last tshirt, the last pair of socks AND the last underwear out of the closet... (lets hope that stuff is dry before i have to work tomorrow morning.) :-)
12:56 PM Tom_L: smaller loads take less overall time to dry
01:00 PM andypugh: Loetmichel: You can microwave damp clothes. It doesn’t really _dry_ them, but it makes them nicer to put on. :-)
01:01 PM Loetmichel: andypugh: no need to
01:01 PM Loetmichel: at 1600 RPM those clothes come fairly dry out of the machine anyways.
01:01 PM Loetmichel: shouldnt take more than 12 hours on the rack even for the jeans to get dry the "natural" way ;)
01:16 PM _unreal_: lot of room cleaning going on here
01:16 PM _unreal_: I finally have some space to move about the cabin ;)
01:21 PM _unreal_: looks like I need to find a socket 775 motherboard that can take 8gb ram
01:25 PM _unreal_: I think I have changed mymind again
01:25 PM _unreal_: and I dont think I'm going to use the i5 for this cnc project
01:26 PM _unreal_: the broken touch screen is a major pain the DISPLAY is really to large its 23"
01:26 PM nubcake is now known as nubcake_
01:26 PM nubcake_ is now known as nubcake
01:26 PM _unreal_: so
01:26 PM _unreal_: I'd be better off using one of these 3 socket 775 computers I have laying around
01:26 PM _unreal_: 4gb ram
01:26 PM _unreal_: pure lcnc no windows on them
01:27 PM _unreal_: and I can get a second parallel port CARD so I can do step feed back
01:27 PM _unreal_: What say you?? guys
01:27 PM _unreal_: OR should I see to maybe a card slot mesa card?
01:28 PM Loetmichel: _unreal_: i have a 775 mobo that can do 16. but its not cheap ;)
01:29 PM Loetmichel: Industrial "flex-atx" mobo
01:29 PM Loetmichel: from IEI
01:30 PM Guest51938: old computer consume alot of power
01:31 PM Loetmichel: Guest51938: thats relative
01:31 PM Loetmichel: ANY computer uses lots of power if you disable all the power management functions to get low jitter for LinuxCNC
01:31 PM Loetmichel: so thats no problem
01:31 PM Guest51938: in a year it will pay for it self
01:32 PM Loetmichel: having an LPT port if you want to do a low price CNC is an issue though
01:32 PM Loetmichel: Guest51938: as i said: it wont in a LinuxCNC setup because powersaving has to be disabled there anyways
01:32 PM Guest51938: even if its diabled
01:33 PM Guest51938: 10watt vs 80-90 watt
01:33 PM Loetmichel: i have Core2 duo systems here that use less than 30W idle and less than 50W when milling.
01:33 PM Guest51938: j1900 for example
01:33 PM Loetmichel: come again?
01:34 PM Guest51938: j1900 consume 10watt
01:34 PM Loetmichel: so?
01:34 PM Loetmichel: thats the cpu
01:34 PM Loetmichel: whats whith the rest of the system?
01:34 PM Guest51938: its on killwatt meter
01:34 PM Loetmichel: HDD? Monitor? DVD if applicable?
01:35 PM Guest51938: not cpu only
01:35 PM Guest51938: ssd im using
01:35 PM Loetmichel: then 10W for the system is a good value
01:35 PM Loetmichel: still not THAT far from the 30w my ages old mill uses
01:35 PM Loetmichel: and thats WITH the 15" display attached and on!
01:35 PM Loetmichel: mill PC
01:36 PM Loetmichel: the mill itself uses a bit more ;)
01:36 PM Loetmichel: but to get back to the point: for a CNC mill Power draw of the CPU is of no concern
01:36 PM Loetmichel: it drowns in the other power hogs on that machie
01:36 PM Loetmichel: machine
01:37 PM Loetmichel: also its not on 24/7 usually
01:53 PM Guest51938: https://www.jarir.com/sa-en/lenovo-ideapad-c340-2-in-1-laptops-528235.html
01:54 PM Guest51938: 2 in 1 lenovo... mybe its the best bet for machine control
01:56 PM Centreline: All the work to find a cheaper computer that uses less power, attached to thousands of euro's of hardware that drinks electricity to move/spin...
01:57 PM Loetmichel: Centreline: indeed
02:00 PM Centreline: I have found the magical 220->110v transformer I had inherited with the house, but its got paper insulation... With no varnish on the wires themselves. What could possibly go wrong there.
02:05 PM Loetmichel: Centreline: sure that its no enamel/magnet wire?
02:06 PM Centreline: no, it looks like paper with bare copper wire, then another layer of paper then more wire. Possibly it has some clear coating but I don't want to disturb it to check inside more...
02:06 PM Centreline: Its very old...
02:07 PM Loetmichel: i have never seen a transformer with bare wire
02:07 PM Loetmichel: even the oldest ones (and i have some from 1850) are enameled/coated wire
02:08 PM Loetmichel: in fact the old ones are more likely to have glass/hemp fibre woven tubes around the wires
02:08 PM Loetmichel: at least on the high current low voltage side
02:10 PM _unreal_: Loetmichel, You'd love the DISPLAY I'm going to use with my cnc
02:10 PM _unreal_: :)
02:10 PM Loetmichel: am i?
02:10 PM _unreal_: again. I get a lot of hardware that is used in the marine industry
02:11 PM Rab: Centreline, you could try checking continuity to the windings with a multimeter. It's possible there's just a very transparent varnish.
02:11 PM Centreline: it has woven tubes on the tails, I just probed a "bare" wire in the core between the paper and its isolated, so a clear coating
02:11 PM Rab: ahh
02:11 PM Loetmichel: thought so ;)
02:11 PM Centreline: I havent seen a transformer with paper between layers for a while though
02:11 PM Centreline: but it was free, and 110v comes out of it, so...
02:12 PM Loetmichel: Centreline: it was standard a while ago
02:12 PM Rab: Of course, with something like that, if you're nervous about using it...then don't use it.
02:12 PM Loetmichel: becausethe old coatings are not so voltage resistant so they wanted to have a bit of insulation between the layers
02:12 PM Centreline: earlier I was accidentally running the 110v suds pump on 220v
02:12 PM Loetmichel: gets quite fast, doesent it?
02:13 PM Centreline: the inrush spike when it started was causing so much noise I got estop errors when it switched state occasionally...
02:14 PM Loetmichel: hihi
02:14 PM Centreline: I fished it out to clean the tank (its in the machine base like most uk bridgeport interact1's) and there it was 110v
02:14 PM Loetmichel: know that feeling
02:14 PM Loetmichel: reason i had the estop on my big CNC router "just for show" for nearly three years
02:15 PM Loetmichel: the estop wire uin the same conduit as the power wire to the VFD for the spindle was a BAD idea
02:15 PM Centreline: I like the e-stop button, I like the pause more, but estop is great in a panic when a toolholder falls out (its qc30)
02:17 PM _unreal_: Loetmichel, I have a 17" marine pilothouse display
02:17 PM _unreal_: it cost someone $3k NEW
02:18 PM _unreal_: in 2008
02:18 PM _unreal_: Its an Italian product
02:20 PM _unreal_: @#!#@$%~!@#$ aahhhhhhh..... archive.org is down for updates etc....
02:20 PM _unreal_: damn it
02:21 PM Loetmichel: have a picture?
02:21 PM _unreal_: its an older monitor and the company went out of business or changed or someting
02:21 PM _unreal_: use to be scsmare.com
02:22 PM _unreal_: with out the internet archive I cant find any photos of the moedel I have
02:22 PM * Loetmichel uses a SDI27 hardened monitor on his company CNC
02:22 PM Loetmichel: SDIP-27
02:22 PM Loetmichel: because it was spare and nobody wants a 15" these days any more
02:23 PM Loetmichel: https://www.youtube.com/watch?v=m7eO5cu-fXg <- and MAN that thing is HEAVY
02:23 PM Loetmichel: (should have used a thicker pin to mount it on)
02:24 PM _unreal_: My monitor is very much like that one in the picture
02:24 PM _unreal_: err video
02:24 PM _unreal_: hard metal back
02:25 PM _unreal_: Though this thing is designed to be mounted IN a face panel
02:25 PM _unreal_: the entire backside is enclosed in a big metal box
02:26 PM Loetmichel: that monitor enclosure is 1mm steel
02:26 PM Loetmichel: welded shut on all corners, not just spot welded
02:26 PM _unreal_: Likely what this thing has
02:26 PM Loetmichel: its airtight if you have all the screws in ;)
02:27 PM _unreal_: though this is not welded
02:27 PM _unreal_: this one is water proof
02:27 PM _unreal_: err water resistant
02:27 PM Loetmichel: and has a 4mm thich front glass coated with ITO
02:27 PM _unreal_: all the electronics have conformal coating
02:27 PM _unreal_: ya this does have the thick GLASS
02:27 PM _unreal_: wish it was touch screen but what ever
02:28 PM Loetmichel: i have some spare 12" touch screens somewhere... had to dismount them from a notebook because they failed the certification (to much RF noise)
02:28 PM _unreal_: The boat that got rid of them did so beause they had no warrenty because the company didnt exist any more
02:28 PM _unreal_: heh
02:29 PM Loetmichel: touch panels, not touch screens, sorry
02:29 PM _unreal_: ahh
02:29 PM _unreal_: resistive or cap.
02:29 PM Loetmichel: capacitive
02:29 PM _unreal_: the good kind
02:29 PM _unreal_: ya I'm thinking about getting a touch panel for this thing
02:29 PM Loetmichel: resisive would probably been OK in the measurement chamber ,)
02:29 PM _unreal_: Thinking about it
02:30 PM _unreal_: to much RF noise?
02:30 PM Loetmichel: yes
02:30 PM _unreal_: I assume that was for work requirements
02:30 PM Loetmichel: yes
02:30 PM Loetmichel: we do TEMPEST shielding and certifying
02:31 PM _unreal_: ahhh
02:31 PM _unreal_: ya cant introduce interferience
02:31 PM Loetmichel: so we basically take Commercial of the shelf IT tech and shield them until they pass the measurement chamber
02:31 PM _unreal_: hum
02:32 PM Loetmichel: and capacitive screens are basically RF transmitters ;)
02:32 PM _unreal_: My company is getting excited for this big new cnc I'm building
02:32 PM _unreal_: going to be close to 30x30"
02:32 PM _unreal_: and 12+ " plunge
02:32 PM _unreal_: I'm thinking about going taller
02:33 PM _unreal_: maybe 20"
02:33 PM Centreline: I finally got sick of a 12" touch screen and picked up a 17" elo from ebay...
02:33 PM Centreline: I can actually see information properly now
02:33 PM Loetmichel: _unreal_: thats biiig
02:33 PM Loetmichel: the bigges one i built had 1500mm by 1020mm by 160mm travel
02:34 PM _unreal_: Loetmichel, this is the base https://drive.google.com/open?id=1n8QM01eo2tG-qUacvH3c_0KZn2RtR0VM
02:34 PM _unreal_: https://drive.google.com/open?id=135fMuE3CmP8uoXCki4YfWx3L5kZ-KPTV
02:34 PM Loetmichel: doesent look soo big
02:34 PM _unreal_: I'm putting rails on the short sides
02:34 PM _unreal_: Loetmichel, that BASE its self is 100 lbs
02:35 PM _unreal_: there are I beams welded across the bottom
02:35 PM Rab: _unreal_, nice base. How flat is it?
02:35 PM Loetmichel: https://www.youtube.com/watch?v=-iYhICZEsCA <- thats the one i built
02:35 PM _unreal_: it use to be the base for a very heavy tranformer
02:35 PM _unreal_: Rab, not sure
02:35 PM _unreal_: doesnt matter to much anways
02:36 PM Loetmichel: ah, converting units error
02:37 PM _unreal_: give you na idea on size there is a fes tool in the background https://drive.google.com/open?id=1liVagaNhtt7j3JF0HNRU3zKudPXCFLPb
02:37 PM _unreal_: ?
02:37 PM Loetmichel: i somehow managed to get 30" = 4m
02:37 PM _unreal_: 4 meters LOL
02:37 PM Loetmichel: 800mm isnt THAT big ;)
02:37 PM _unreal_: Loetmichel, not bug but I'm making it VERY strong
02:37 PM Loetmichel: i noticed ;)
02:38 PM Loetmichel: have you seen the vid?
02:38 PM _unreal_: the rails that are going to be mounted on the sides "the short sides" are 4x4" 1/4" thick aluminum stock
02:38 PM Loetmichel: that was roughly 300kg of 21mm marine plywood...
02:39 PM Loetmichel: was a PITA to get it out of the old (cellar) shop and into the sprinter bus
02:39 PM Loetmichel: when the boss sold the company
02:39 PM Centreline: hehe and the sprinter didnt collapse from rear chassis rot? well done :D
02:40 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=4053 <- thats the inside of the base plate
02:40 PM Centreline: (disclaimer, I have a old sprinter)
02:40 PM Loetmichel: that video was shot in the new location
02:40 PM Loetmichel: no, was a rental
02:40 PM Loetmichel: no rot there ;)
02:41 PM Centreline: lucky, mine seems to evaporate in real time :)
02:41 PM Loetmichel: noticed the dust extraction system?
02:41 PM Loetmichel: went to 2 vacuum hose each year in the old place
02:42 PM Loetmichel: decided to use 50mm drainage pipe on the new location
02:42 PM Loetmichel: more wall thickness to eat thru for the glass/carbon dust
02:42 PM _unreal_: Loetmichel, I'm still trying to decide what type of rail system I want to do?
02:42 PM _unreal_: and how I want to set it up
02:43 PM _unreal_: I'm adding 8" of width to the wider side of that base
02:43 PM _unreal_: and the rail will extend out a bit mainly in the backside
02:43 PM _unreal_: so I will have a waste board that covers the floating area
02:44 PM Rab: _unreal_, profile rails, no contest. (Unless you have cheap/free round rails!)
02:44 PM _unreal_: profile rails?
02:44 PM Rab: Square rails, like hiwin style.
02:44 PM Loetmichel: THK rails
02:44 PM Loetmichel: or hiwin, indeed
02:45 PM _unreal_: I'm leaning twards theses shttps://images-na.ssl-images-amazon.com/images/I/61ldmnYUEgL._SL1500_.jpg
02:45 PM _unreal_: type
02:45 PM _unreal_: and I'm looking at using a track on the TOP and bottom
02:45 PM _unreal_: of the square stock
02:45 PM _unreal_: per side
02:45 PM _unreal_: of the base
02:46 PM Rab: Those round rails are a little more tolerant of misalignment, but less rigid (in both cases, because there's nothing to keep the bearing from rolling axially).
02:47 PM _unreal_: thats what I figure
02:47 PM _unreal_: BUT I'm also looking at a big work area
02:47 PM _unreal_: and if I put rails on the top and bottom of the square stock
02:47 PM _unreal_: I kind of negate that issue
02:47 PM _unreal_: would I not
02:48 PM Rab: That would mitigate static misalignment, but maybe not vibration and resonance where the top and bottom bearings would be in different modes.
02:48 PM Centreline: if you put rails top and bottom, is there a risk of it locking up when it distorts under load?
02:49 PM _unreal_: I'd likely have to draw a photo to give na idea of what I'm talking about
02:50 PM _unreal_: T@Q#$% mouse battery dead again
02:50 PM _unreal_: ok give me a sec and I
02:50 PM _unreal_: I'll draw a photo
02:51 PM _unreal_: I could set them up like this kind of
02:51 PM _unreal_: just much closer being 4" stock
02:51 PM _unreal_: https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcSLiNsV9LhdYuCI3asmQuDoX9RMevi359vlL6ma_ON6TYJDDoca
02:53 PM Rab: _unreal_, rails in parallel like that, or opposed mounting on top and bottom of the stock?
02:56 PM _unreal_: https://drive.google.com/open?id=1awFqRe-lEe-XDiweUvPLtXzOC6ZOW8jg
02:56 PM _unreal_: I'm thinking top/bottom
02:57 PM _unreal_: but paralle on the side is an option as well
02:57 PM _unreal_: but I think top/bottom would be the wiser
02:57 PM _unreal_: https://drive.google.com/open?id=1M0AEWYBorOkzJdJ7BxX0mm7LE6aypqcy
02:57 PM _unreal_: mounted to a setup like that
02:58 PM _unreal_: ?
02:59 PM Rab: _unreal_, I see.
03:00 PM _unreal_: I could mount the bottom one's fixed, and the top one's with an up/down adjustment tension system
03:00 PM _unreal_: everything in this build is going to have adjustment
03:01 PM _unreal_: dont want to but its going to be so strong I need to be able to adjust parts
03:01 PM _unreal_: That or spend a small fortune to have everything milled perfect
03:01 PM _unreal_: So what are your thoughts
03:01 PM _unreal_: Loetmichel, ?
03:02 PM Loetmichel: yes?
03:02 PM Loetmichel: reading backlog, moment
03:02 PM _unreal_: just updated the photo https://drive.google.com/open?id=1-0eXTf9ow_qJYQ8AgDgeRAHTOd-e6zcF
03:03 PM Loetmichel: is that x or y?
03:03 PM Loetmichel: in y you dont need it
03:03 PM Loetmichel: one rail is enough on each side
03:03 PM _unreal_: Y
03:04 PM Loetmichel: the gantry prevents the "rolling" of the bearings
03:04 PM _unreal_: Loetmichel, I'm looking at doing aluminum milling
03:04 PM _unreal_: and my Z may be as high as 20" plunge
03:04 PM Loetmichel: and in x i would do a LOT higher gantry profile
03:04 PM _unreal_: I'm trying to minimize flex
03:04 PM Loetmichel: you still dont need it
03:04 PM Loetmichel: the gantry has to be rigid
03:04 PM Loetmichel: you dont NEED any "roll prevention" on the sides
03:05 PM Loetmichel: and if the gantry isnt rigid the double rails will not help any
03:06 PM Loetmichel: look at this machine and note where the boxed in sections and rails are, it IMHO doesent get any better statically: http://www.cyrom.org/palbum/main.php?g2_itemId=11205&g2_imageViewsIndex=1
03:07 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=11172&g2_imageViewsIndex=1 <- the back of the gantry is closed after mounting the stepper of course
03:07 PM _unreal_: hehe you have twin rails on X
03:08 PM _unreal_: I'm building this machine out of 1" thick aluminum
03:08 PM _unreal_: I have a source to get it for free
03:08 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_view=core.DownloadItem&g2_itemId=11178
03:08 PM _unreal_: The water jetting isnt going to be cheap
03:08 PM _unreal_: but its going to be heavy
03:08 PM Loetmichel: its PRETTY rigid ;)
03:08 PM _unreal_: and rigid
03:08 PM Loetmichel: and yes it can mill aluminium
03:09 PM Centreline: free 1" aluminium, do you have lots of friends? :D
03:10 PM _unreal_: there are companies in south florida that do BIG work
03:10 PM _unreal_: and what they call drops are to small to use
03:10 PM _unreal_: and more then big enough for my mill
03:10 PM Loetmichel: hihi
03:10 PM Loetmichel: yes, its a probelm of scale ;)
03:10 PM Loetmichel: still scrap alu is pretty valuable
03:10 PM _unreal_: ya
03:11 PM Loetmichel: so be grateful that they gift it to you
03:11 PM Centreline: its the hardest part of owning a machine for me
03:11 PM _unreal_: so the new welder at the company is going to try to get me a bunch of drops
03:11 PM Loetmichel: Centreline: hmm?
03:11 PM Centreline: I have this bridgeport, and a wire edm, plus lathe etc, but I have to fight for scraps with the others
03:11 PM Loetmichel: sourcing the alu=
03:11 PM Loetmichel: ?
03:11 PM Centreline: yes, sourcing any materials with graded properties
03:11 PM _unreal_: when I get the material the expensive part will be having the water jet company cutting the parts
03:12 PM Centreline: I have no xrf equipment to verify...
03:12 PM _unreal_: xrf
03:12 PM _unreal_: ?
03:12 PM Loetmichel: radar/xray based materials analysis gun
03:12 PM Centreline: and I'm in france, and not a enterprise, and nobody sells stock to individuals here
03:12 PM _unreal_: ahh
03:12 PM _unreal_: heh
03:13 PM _unreal_: ya south florida USA here
03:13 PM Centreline: so I have to fight with the 3d printer crowd on ebay for the bigger juicy scraps
03:13 PM Centreline: and materials they cant cut :)
03:13 PM _unreal_: speaking of its currently 82F outside :)
03:13 PM * Loetmichel just orders alu in any size up to 3m by 2m and up to 50mm thickness from the local metal dealer
03:14 PM Loetmichel: not cheap though
03:14 PM Loetmichel: and a bunch of different alloys
03:14 PM _unreal_: Loetmichel, ok an other opinion question for you
03:14 PM _unreal_: I have 4 460oz/in steppers
03:15 PM _unreal_: I'm toying with using toothed pullies and gearing down one motor to drive both lead screws
03:15 PM _unreal_: OR two motors each with gear reduction pullies reardless
03:15 PM _unreal_: think I could get away with one?
03:15 PM Loetmichel: i wouldnt use one motor on y
03:15 PM Loetmichel: use two
03:15 PM Loetmichel: and link the ballscrews on the other end
03:16 PM Loetmichel: i had 3Nm steppers on "my" big CNC
03:16 PM Loetmichel: and it lived for half a year on one stepper ... until the sync belt in the back broke
03:16 PM _unreal_: 3Nm? thats like 27 foot lbs if I'm right?
03:16 PM _unreal_: heh
03:16 PM _unreal_: ?
03:17 PM _unreal_: so it had plenty of power just the belt failed
03:17 PM Loetmichel: 3 nM is like 400oz/in
03:17 PM Loetmichel: Nm
03:17 PM _unreal_: oh
03:17 PM Centreline: 424oz/inch
03:17 PM Centreline: I had to google too :D
03:17 PM Loetmichel: still could kick the new owner of the machine for doing that to it
03:18 PM Centreline: this bridgeport has 8nm, and theyre not big enough at times...
03:18 PM Centreline: but different type of machine, it has to throw lumps of cast iron about
03:18 PM Loetmichel: a brideport has no ballscrews but acme IIRC
03:18 PM _unreal_: oh sorry 425oz
03:18 PM Loetmichel: and it has a LOT more weight to move ;)
03:18 PM _unreal_: https://www.amazon.com/gp/product/B07236CFKC/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
03:18 PM Centreline: this is ballscrews (its a interact)
03:18 PM _unreal_: that is what I have
03:19 PM Centreline: the interact were ballscrews on everything but the knee elevation which is manual (the quill is ballscrew)
03:19 PM Loetmichel: Centreline: those gantry mills usually have high speed spindles and small mill bits
03:19 PM Loetmichel: you dont need a ton of force
03:19 PM Loetmichel: but you need speed
03:20 PM Centreline: yes its not a direct comparison at all
03:20 PM Centreline: I just bought a vmc with a 20k spindle when I can work out how to get it home...
03:21 PM _unreal_: Loetmichel, what I'm looking at is using a single motor geared down and split pulleys single pully to left and right. and single cog setup in the middle
03:21 PM Centreline: I imagine thats going to be a whole new area of learning...
03:21 PM _unreal_: That is geared down from the stepper motor
03:22 PM _unreal_: so you dont think it would be a good idea to use single motor then
03:23 PM _unreal_: I'm looking at 12:1 reduction iirc
03:24 PM _unreal_: So motor with small cog to big cog 3.5:1 and then an othe dual small cog to much larger cogs on the lead screws ball screws that are 8.5:1
03:25 PM _unreal_: something like 10-12 : 1 ration
03:25 PM _unreal_: ratio
03:25 PM _unreal_: ?
03:27 PM _unreal_: and everyone goes quiet
03:28 PM _unreal_: well back in 3 hours. got to go get the kid from the bitch
03:30 PM Loetmichel: _unreal_: dont gear down that much+
03:30 PM Loetmichel: you need to have speed
03:30 PM Loetmichel: especially if its big
03:30 PM Loetmichel: 10mm/sec should be possible or you will wait for ages if you have a lot of cross table moves
03:30 PM Loetmichel: 100mm/sec
03:31 PM Loetmichel: i had mine geared down 2:1
03:31 PM Loetmichel: on 16*4mm ballscrews
03:32 PM Loetmichel: if you have 16*10mm or similar you can maybe gear down 4:1
03:32 PM Loetmichel: but i wouldt do more
03:32 PM Loetmichel: or you lose speed
03:37 PM Centreline: do you mean 10mm/second linear speed?
03:40 PM Loetmichel: 100mm/second linear speed
03:40 PM Loetmichel: or at least 70mm/sec
03:41 PM Loetmichel: not for milling, i did 3mm double layerd glass fibre board at 40mm/sec though
03:41 PM Loetmichel: but for G0 moves across the table
03:42 PM Loetmichel: they take aaages if you have a square meter or more on travel
04:00 PM Centreline: I dont know how that maps to settings, but the mill scares the hell out of me milling at F1200 with a 16mm slot drill 2mm deep...
04:00 PM SpeedEvil is now known as Guest53637
04:00 PM Centreline: but I'm a hobbyist so I've slowed it down since
04:02 PM Centreline: plus I noticed the chinese toolholder tend to come loose under heavy loads, because the flange which the qc system uses to locate them are not consistent like eg the erikson ones
04:05 PM Centreline: this is in aluminium of course, I can't mill steel at those rates without flood working
04:16 PM BitEvil is now known as SpeedEvil
04:23 PM jthornton: XXCoder, making parts in freecad is rather easy
04:24 PM Tom_L: jt, gettin to where you like it?
04:25 PM Centreline: that suds pump sure sounds happier at 110v, but its still occasionally causing a estop when switching state...
04:42 PM Centreline: time to pull the plug, gnite all
04:58 PM jthornton: yea it's ok, just a few things are different but I can do most things in freecad that I can do in sw
05:00 PM Tom_L: is the cam workable?
05:01 PM jthornton: didn't try that, I'm just making parts for my printer... someone said anders wallen is working on the cam
05:01 PM Tom_L: ahh
05:02 PM Tom_L: been trying to get my 7i80 connected
05:02 PM Tom_L: i think the network card may be the culprit
05:02 PM Tom_L: of 3 pcs none can see it
05:03 PM jthornton: what does angry ip show?
05:03 PM Tom_L: never used it
05:03 PM Deejay: gn8
05:04 PM Tom_L: doesn't show up in the hardware list in win or linux
05:09 PM Tom_L: don't think that will work since there's no ip assigned to it yet
05:09 PM Tom_L: can't see the hardware
05:13 PM jthornton: I assume it's like other ethernet cards and you jumper select what ip address it uses?
05:13 PM jthornton: if it is on you won't see it on your lan
05:15 PM jthornton: yup just looked in the manual and it is jumper selected
05:18 PM Tom_L: right, i've tried both
05:18 PM Tom_L: i'd still need to set it up in the os first
05:19 PM Tom_L: and since it doesn't see the hardware that's kinda hard to do
05:25 PM jthornton: if it's set to your nic needs to be set to 10.10.10.something other than 10
05:26 PM jthornton: if it's set for 192.168.1.whatever your lan needs to be
05:26 PM Tom_L: i've had it set and working but i had to swap pcs
05:26 PM jthornton: did you set the nic to a static ip of
05:26 PM Tom_L: just setting up the test pc again
05:27 PM Tom_L: not in interfaces
05:27 PM Tom_L: dunno what to call it since they don't use eth0 eth1 now
05:28 PM jthornton: https://gnipsel.com/linuxcnc/uspace/linuxmint19-eth.html
05:28 PM Tom_L: i used that
05:28 PM Tom_L: well, not the mint one
05:28 PM jthornton: and w2 is up on the 7i80?
05:28 PM jthornton: they are all the same pretty much
05:28 PM Tom_L: it was but i tried both ip address's
05:28 PM Tom_L: right
05:29 PM Tom_L: i've got a 7i92 to test with as well
05:29 PM jthornton: get angry ip
05:29 PM XXCoder: jthornton: yeah it is basically
05:29 PM * jthornton heads out to the shop
05:30 PM Tom_L: i got angry ip
05:30 PM jthornton: just takes a bit to get used to the interface and how freecad does things but I've made a dozen parts today lol
05:30 PM Tom_L: heh
05:30 PM Tom_L: gotta run for a bit
05:30 PM XXCoder: man I guess having sw background helps
05:30 PM XXCoder: I had to learn a lot and make parts off plans I found online.
05:30 PM jthornton: set the jumper to and tell angry ip to search for -
05:31 PM XXCoder: someday ill send you that nightmare of a part lol
05:31 PM jthornton: yea it was a huge help knowing how to create parametric parts as I know what I want just had to figure out how freecad gets there
05:31 PM jthornton: I should make some tutorials lol
05:31 PM XXCoder: please do
05:33 PM drdoc: hey, I have a noob question
05:34 PM drdoc: if I run the port tester at the cable end, I get 5V between pin 1 & GND when I click the pin 1 button
05:36 PM drdoc: but connected to the 5V-powered breakout board, pin1 and the board's GND pin, I get nada
05:36 PM drdoc: is the breakout board dead?
05:41 PM jthornton: that's one possibility...
05:42 PM andypugh: Is the 5v breakout board being powered by 5v?
05:44 PM drdoc: andypugh: it is, via the USB port
05:45 PM andypugh: You are testing at the end of the cable, so we can be confident that this isn’t one of those annoying part-wired cables?
05:46 PM drdoc: yes.
05:46 PM drdoc: it may be, but there's definitely signal at the end of Pin 1
05:47 PM drdoc: oh for fucks sake
05:47 PM drdoc: the leftmost step/dir pin on that board is NOT Pin 1
05:48 PM drdoc: PEBCAK
05:48 PM jthornton: glad we solved that one
05:48 PM drdoc: well, it ain't working, so there's still a problem
05:49 PM * drdoc goes to see if pushing the right button lights the right pin
05:50 PM * jthornton starts another test print of the medicine cabinet magnetic latch cover
05:57 PM Tom_L: jthornton, angry ip found nothing from to
05:57 PM Tom_L: i'm thinking the network card is bad
05:58 PM jthornton: I've also had problems with the rj45 plug and had to plug in and out a few times to wipe the contacts
05:59 PM jthornton: rj45 plug on my cable I assume
05:59 PM Tom_L: i don't get any leds after the initial startup ones and usually one stays lit
05:59 PM Tom_L: yeah
05:59 PM jthornton: does the nic led blink like it's yacking to the card
05:59 PM Tom_L: i tried the MB ethernet and at least it stayed lit on the mesa card
06:00 PM Tom_L: no activity lights on the plug like you normally see
06:00 PM jthornton: yea you should use the mb nic
06:00 PM Tom_L: no blinkies
06:00 PM jthornton: we need blinkies
06:00 PM Tom_L: that's why i'm fairly sure the pcie card is bad
06:01 PM * jthornton is cooking jambalaya in a few minutes
06:01 PM jthornton: yea if angry ip don't find it something is wrong
06:01 PM jthornton: or broken
06:01 PM Tom_L: i dual boot this so i don't want to change too much hardware
06:02 PM Tom_L: but i may try the MB nic
06:02 PM Tom_L: just to see
06:02 PM jthornton: if your lan is 192.168.1 set w2 down and see if angry ip sees it if you plug it into a switch
06:02 PM jthornton: mb nick is the best to use
06:02 PM XXCoder: theres also possibility of jabber heh
06:02 PM Tom_L: yeah that's what i hear... i've had this working before though
06:02 PM jthornton: don't forget to set the static ip
06:03 PM XXCoder: once had one card start jabbring though it was still working sometimes. made it really hard to find
06:03 PM XXCoder: tom you could get a hub (not switcher) and have another device listen to your machine output
06:07 PM Tom_L: see, on the switch it shows activity lights on the mesa card
06:16 PM Tom_L: mmm, looked at the board... very questionable solder job on the connectors etc
06:16 PM Tom_L: gonna try some rework here..
06:17 PM drdoc: bleah
06:17 PM drdoc: breakout board's pins 2-9 are dead
06:18 PM drdoc: which suggests to me that the problem was my wiring, not the board
06:27 PM andypugh: drdoc: It’s traditional to blame the Chinese, not your own errors.
06:28 PM XXCoder: lol
06:29 PM drdoc: andypugh: I tried hard
06:29 PM jthornton: well that print went from ok to bad quick
06:29 PM drdoc: I just can't quite convince myself that the chinese screwed up *only* the outputs I connected
06:29 PM drdoc: jthornton: whatcha printing?
06:30 PM jthornton: lol a shelf over the magnetic latch in my medicine cabinet
06:30 PM XXCoder: entire shelf or supports for it?
06:31 PM drdoc: andypugh: I still have a hard time understanding how I blew up the *outputs*
06:31 PM jthornton: just a flat spot over the latch
06:31 PM jthornton: which is basically wasted space
06:31 PM XXCoder: cool :)
06:31 PM drdoc: thgat's kind of a coincidence...
06:32 PM drdoc: I was just about to start drawing up a magnetic latch for my partner's bathroom cabinet
06:33 PM drdoc: somebody went to the trouble of unscrewing the original latch, both door & frame
06:34 PM drdoc: so she ordered a set of magnets off Amazon, wants me to make "a pretty mount for them"
06:36 PM drdoc: 2 pair of 10mm diameter 3mm thick neodyniums
06:36 PM drdoc: I guess she's finished opening that cabinet
06:36 PM drdoc: :)
06:41 PM SpeedEvil: As a general point, don't let the magnets smack into each other. A layer of tape over them stops cracks
06:42 PM drdoc: SpeedEvil: If those are decent neos, she'll get tired of them *real* fast
06:42 PM drdoc: 10x3 disk-to-disk is a pretty good hold
06:43 PM _unreal_: Hate that fucking drive
06:43 PM andypugh: You will need to pretty good glue to hold them in to the moiunts.
06:44 PM drdoc: I'm going to use a couple of my 5mm diameter x 3mm and a steel plate, and just not mention it
06:44 PM XXCoder: tried to fix printer. ulimately a failure, I need longer m3 bolts lol
06:44 PM andypugh: You have a choice of doing exactly as asked, or explaining the problem :-)
06:44 PM drdoc: andypugh: or just doing it right and not saying anything till I'm asked
06:45 PM jthornton: 6 hens on one side and 1 on the other side and none in the middle
06:45 PM drdoc: She's pretty good about accepting an already-working solution, even if it's not what she asked for
06:45 PM andypugh: Sounds fraught with danger of being “found out” and having to “explain yourself”
06:45 PM andypugh: But I might have a rather warped experience with girlfriends.
06:45 PM drdoc: so, a day that ends with "y"?
06:46 PM drdoc: I've made that exact mistake with magnetic latches
06:46 PM Tom_L: jthornton, pretty sure the card is bad. the mb nic works fine
06:46 PM andypugh: Not a German then?
06:47 PM drdoc: all she needs is a stop to keep the door from closing past 0*, and enough magnet to keep it from swinging by itself
06:47 PM andypugh: (where days end with a g)
06:47 PM drdoc: pure texan, thankyaverymuch
06:47 PM andypugh: Handbag magnetic catches look good for things like that. And possibly for plasma torch mounting too.
06:48 PM drdoc: if she gripes about it I'll let her try to get those 10x3 apart
06:48 PM drdoc: the secret to mounting a magent successfully is to put it *behind* the mount
06:49 PM drdoc: 1mm of PETG will keep it in place without much affecting the hold
06:49 PM drdoc: dadblame it
06:50 PM drdoc: I'd really like to know how I fried that board
06:52 PM drdoc: those 74245s ought not be that fragile
06:53 PM andypugh: reverse voltage?
06:53 PM Tom_L: andypugh do you recall the mesaflash command to set the 'user ip' on a board?
06:53 PM Tom_L: it's been a long time since i've messed with it
06:54 PM andypugh: No
06:54 PM drdoc: andypugh: you mean from the 5V supply?
06:54 PM drdoc: the LED wouldn't light if it were reversed
06:54 PM Tom_L: well, at least i can verify it's address...
06:54 PM andypugh: --set set board IP address in eeprom to n.n.n.n (only ethernet boards)
06:54 PM Tom_L: yeah
06:54 PM andypugh: (from mesaflash —help_
06:54 PM Tom_L: i've got notes somewher, just can't find them
06:55 PM Tom_L: don't remember if i need to jumper something first though
06:56 PM Tom_L: ahh found it in the doc
06:56 PM andypugh: drdoc: Ignore me, I forgot that you were talking about outputs.
06:56 PM drdoc: I'd be a lot less surprised about blown inputs
06:57 PM drdoc: like I said, 74xx245 are pretty hardy chips
06:58 PM andypugh: Ah, but are they _really_ what they claim to be?
06:58 PM drdoc: I dunno
06:58 PM andypugh: In a world where there are fake capacitors (identical, but just no electrolyte)....
06:58 PM Tom_L: ok i figured it out. thanks anyway
06:58 PM drdoc: I probably have a couple of 5V DIP parts in my bag o' chips
07:00 PM drdoc: I just need to look & see if they're current-compatible
07:17 PM _unreal_: So I believe my best choice is to use one of these socket 775 computers I have
07:18 PM _unreal_: I hav e 4gb ram for each of them and non of them support more then that
07:18 PM _unreal_: :/
07:18 PM drdoc: _unreal_: my C2Q only has 4GB
07:18 PM drdoc: past that, it looks like a good video card matters more than RAM
07:19 PM _unreal_: define "good"
07:19 PM _unreal_: :)) nvidia TNT2
07:23 PM _unreal_: ?
07:23 PM _unreal_: heh
07:24 PM _unreal_: lcnc minimum 700mhz 384mb ram
07:46 PM _unreal_: shhhhhhhhhhhhhhhhhh
07:47 PM XXCoder: 4 gb hd
07:47 PM _unreal_: hd?
07:47 PM XXCoder: hard drive
07:48 PM XXCoder: thats all it needs if its just to run machine
07:48 PM _unreal_: heh
07:48 PM XXCoder: mine has 8 gb ssd
07:48 PM _unreal_: so XXCoder I think I'm going to use one of my towers I have
07:48 PM _unreal_: all of them are 775 cpu's
07:48 PM _unreal_: and 4gb ram
07:49 PM XXCoder: dont use inbuilt video card
07:49 PM XXCoder: get that era good video card
07:49 PM XXCoder: turn off all power saving stuff
07:49 PM _unreal_: I hav e plenty of gpus
07:50 PM XXCoder: cool :)
07:53 PM _unreal_: lol LEnuxcnc
07:53 PM _unreal_: https://www.youtube.com/watch?v=OpkDz6F7yko
07:54 PM XXCoder: its a dell!
07:55 PM _unreal_: dude he's using a dell
07:56 PM _unreal_: XXCoder, I was going to use that other computer the i5
07:56 PM XXCoder: cool :)
07:56 PM _unreal_: but the issue is that the touch display is broken CRACKED and I have not scrapped it off
07:56 PM _unreal_: the display IMO is a little large
07:57 PM _unreal_: 23"
07:57 PM _unreal_: and there is NO par port on it
07:57 PM _unreal_: I'd have to get a micro PCI card to add it
07:57 PM XXCoder: cant order display on ebay?
07:57 PM _unreal_: or go with a mesa
07:57 PM _unreal_: no
07:57 PM _unreal_: the display is fine
07:57 PM _unreal_: its the @$#%Q$#W%@#4 touch display
07:57 PM FleaFart_ is now known as FleaFart
07:57 PM _unreal_: its part of the front bezel
07:58 PM _unreal_: so I'm going to just use it at home as a win10 computer
07:58 PM FleaFart is now known as LittleStinker
07:59 PM _unreal_: heheh DEEbian w
08:16 PM _unreal_: OMG I have so many options for a computer to use for the lcnc setup
08:16 PM XXCoder: now including rpi4
08:16 PM _unreal_: I dont have an RPI4
08:16 PM _unreal_: I do have a tinkerboard setup with lcnc
08:17 PM _unreal_: but no gpio DRIVER for it :(
08:17 PM XXCoder: I know im just saying its possible now :)
08:17 PM _unreal_: I'd have to go wtih mesa
08:17 PM _unreal_: know=now
08:17 PM XXCoder: yeah if I went for rspi4 I'd have to buy mesa also
08:17 PM _unreal_: omg hehehe My mind goes to fast. My daughter is YACKING at me and I read your know and was like NOW damn it why did I write that
08:18 PM _unreal_: the tinkerboard had a jitter of 40,000 as I recall
08:18 PM XXCoder: 40k isnt best but workable
08:18 PM _unreal_: with multi copys of glxgears and other stuff running
08:18 PM _unreal_: considering what it is
08:19 PM _unreal_: thats mind blowing
08:19 PM XXCoder: yeah
08:19 PM _unreal_: just wish someone could come up with the @#$%@#$%!#@$ GPIO driver
08:19 PM XXCoder: whats yp with your kid cnc machine
08:19 PM _unreal_: problem?
08:19 PM _unreal_: no problem
08:19 PM _unreal_: non that I know of anwyays
08:19 PM _unreal_: I just have one part left to mill
08:19 PM XXCoder: its finished and running alre ahh ok
08:19 PM _unreal_: and a few more parts to put to gether and I can start on electronics
08:20 PM _unreal_: let me snap current photo
08:21 PM XXCoder: https://www.youtube.com/watch?v=kqLoC2U5u-g GREAT video so far. 24 min video
08:22 PM XXCoder: im not understanding part at approx 15 min tho
08:22 PM XXCoder: mill flat, then weld on hmmm
08:22 PM drdoc: _unreal_: I got a couple of usec latency difference going from a 256mb GeForce to a 1GB Radeon
08:23 PM _unreal_: https://drive.google.com/open?id=1VwGnMSwEfKYXftK5wZZLsn3IM9XS1xCD
08:23 PM _unreal_: usec?
08:24 PM _unreal_: what do you think?
08:25 PM drdoc: microseconds
08:26 PM drdoc: can't see that doc, I'm on my phone
08:26 PM _unreal_: OMG wtf is wrong with that guy. a standard map gas torch would have been a better choice then FORCING the nut
08:26 PM _unreal_: doc?
08:27 PM _unreal_: its a picture
08:27 PM _unreal_: there is no reason you cant see the link on that
08:27 PM _unreal_: unless I didnt enable link sharring
08:27 PM _unreal_: sharing
08:27 PM XXCoder: unrel think its cast metal, cannot torch it without losing temper
08:27 PM _unreal_: https://drive.google.com/open?id=1VwGnMSwEfKYXftK5wZZLsn3IM9XS1xCD
08:27 PM _unreal_: that link should work just fine
08:27 PM _unreal_: works on my phone
08:28 PM drdoc: it's tiny!
08:29 PM _unreal_: XXCoder, that is NOT cast metal you can see mill marks in it
08:29 PM drdoc: I had to twiddle a bit to see it.
08:29 PM _unreal_: the feet are even welded on
08:29 PM _unreal_: drdoc, so you like?
08:29 PM XXCoder: hmm dunno then heh
08:30 PM drdoc: terminal app on phone > ssh to server > irssi > #linuxcnc
08:30 PM drdoc: it looks solid, but there's not that much visible
08:30 PM _unreal_: XXCoder, at to 2:30 he FUCKS it up
08:31 PM _unreal_: SHOULD HAV E USED heat
08:31 PM _unreal_: dudes a moron
08:31 PM XXCoder: lol
08:32 PM _unreal_: if it was CAST it would have shatterd under the dynamic load when the supports gave way
08:32 PM drdoc: is the CNC4PC C-10 board worth $15 more than the ChinaCo 5-axis breakout?
08:32 PM _unreal_: ?
08:32 PM _unreal_: cnc4pc?
08:32 PM _unreal_: never heard of it
08:32 PM _unreal_: is it LCNC compat
08:32 PM _unreal_: ?
08:32 PM Tom_L: cheap cards
08:33 PM drdoc: I just returned the one I blew up as defective
08:33 PM _unreal_: OMG he drills it out
08:33 PM XXCoder: hes not
08:34 PM XXCoder: watch it some more
08:34 PM _unreal_: MORON. that pin was likely an interference install meaning it was PUT in place with heat
08:34 PM _unreal_: and cold
08:34 PM drdoc: Tom_L: options are that, another Chinese cheapo, or breadboard one myself
08:35 PM drdoc: or something else that costs < $25
08:36 PM XXCoder: heat/cold inference fit yeah now that you menion uit, its likely to be that
08:36 PM drdoc: I'm kind of leaning toward making one. I have everything on hand except screw terminals
08:36 PM Tom_L: if you're going that route a chinaco one would be as good as anything
08:36 PM Tom_L: you can't make one for less i doubt
08:37 PM drdoc: I'm pretty sure making one would cost more
08:38 PM drdoc: but known quality parts is worth a few bucks
08:38 PM _unreal_: got links?
08:38 PM Tom_L: google.com
08:38 PM _unreal_: Your cheating
08:39 PM drdoc: links to?
08:39 PM Tom_L: https://www.ebay.com/itm/5-Axis-CNC-Breakout-Board-with-Optical-Coupler-for-MACH3-Stepper-Motor-Driver/123554335456?hash=item1cc4698ae0:g:EGEAAOSwqH9bdDBk
08:40 PM Tom_L: https://www.ebay.com/itm/1X-MACH3-CNC-5-Axis-Interface-Breakout-Board-for-Stepper-Motor-Driver-Controller/173323933239?hash=item285ae95637:g:3KkAAOSwHSddoYqi
08:40 PM _unreal_: thats a mach3 usb board
08:40 PM _unreal_: I thought they dont work with lcnc
08:40 PM XXCoder: thats standard BOB
08:40 PM XXCoder: it works fine.
08:40 PM Tom_L: looks like a parallel port connector to me
08:40 PM _unreal_: huh?
08:41 PM XXCoder: breakout board
08:41 PM _unreal_: OH I saw the sub
08:41 PM drdoc: _unreal_: usb port is just power in
08:41 PM _unreal_: so usb for power
08:41 PM Tom_L: yeah it's just to confuse ya
08:41 PM _unreal_: WORKED
08:41 PM Tom_L: they use usb ports for everything nowdays
08:41 PM Tom_L: get with it man...
08:41 PM _unreal_: lcnc IMO should support USB motion controllers
08:41 PM Tom_L: no
08:41 PM drdoc: Tom_L: I got one like that off Amazon, just sent it back
08:42 PM Tom_L: they never will
08:42 PM Tom_L: usb is NOT realtime
08:42 PM XXCoder: yeah no rt anywhere in usb system
08:42 PM _unreal_: nether are MESA
08:42 PM drdoc: the output pins worked, poorly, for about 45 minutes
08:42 PM _unreal_: they are "semi" real time
08:42 PM Tom_L: i'd rather not 'semi' break a tool over it either
08:43 PM _unreal_: I'm half tempted to go with one of the newer planetcnc controllers
08:43 PM drdoc: USB is evil, in almost every way
08:43 PM Tom_L: _unreal_ why not get a mesa card?
08:43 PM XXCoder: usb is pretty good, but nothing good for cnc machines
08:44 PM _unreal_: XXCoder, My ome cnc is using a planetcnc controller thats USB based
08:44 PM _unreal_: it has all the features of lcnc
08:44 PM XXCoder: mesa being "semi realtime" not sure what that means
08:44 PM _unreal_: meaning it takes the pulse packets and turns them into smooth realtime
08:44 PM _unreal_: in hardware
08:44 PM drdoc: XXCoder: Also Could base a comment about ATA133 that applies equally to USB
08:44 PM Tom_L: _unreal_, it offloads work
08:44 PM _unreal_: and I'm more so refering to the network versions
08:45 PM Tom_L: critical timing stuff
08:45 PM _unreal_: EXACTLY
08:45 PM drdoc: "Even a pig will fly, given enough thrust."
08:45 PM _unreal_: which is what the USB controlelrs are doing as well
08:45 PM Tom_L: _unreal_, 7i80 7i92
08:45 PM _unreal_: drdoc, chears
08:45 PM _unreal_: cheers
08:45 PM _unreal_: I'm drinking mead tonight
08:45 PM drdoc: lol, autocorrect
08:46 PM drdoc: "Alan Cox"
08:46 PM XXCoder: "network version" isnt that not actually networking but realtime commucatuon using ethernet cable as media?
08:46 PM XXCoder: i dont know mesa ethernet
08:46 PM _unreal_: its STILLLLLLL a packet driver
08:46 PM _unreal_: PACKET driving iis NOT real time
08:47 PM Tom_L: if you want to argue that, nothing is realtime
08:47 PM drdoc: it's as close to RT as parallel port
08:47 PM _unreal_: Thats why i will ALWAYS consider the EEEWWWW usb isnt realtime AS BULL shit. because there are mother methods being used that are NOT real time and ARE SEMI real time being used
08:47 PM Tom_L: everything has latency
08:47 PM _unreal_: Tom_L, I agree fully nothing is truly realtime :)
08:48 PM drdoc: a good ethernet adapter buffers packets
08:48 PM Tom_L: these cards come as close as you can get to it
08:48 PM drdoc: and anything not TCP streams at near line speed
08:49 PM _unreal_: OMG soo many computer options
08:49 PM _unreal_: brb need to tuck the brat in ;)
08:49 PM _unreal_: and give hugs and kisses
08:56 PM _unreal_: ok I'm bac
08:56 PM _unreal_: I see no one missed me
08:57 PM _unreal_: dohj
08:57 PM _unreal_: sigh
08:57 PM XXCoder: lol
08:57 PM XXCoder: well did you finish that video?
08:58 PM _unreal_: no
08:58 PM _unreal_: I was dealing with my daughter
08:58 PM XXCoder: lol well basically hes drilling part of bolt, not all of it out
08:58 PM XXCoder: so it have easier time deforming to get out
09:15 PM _unreal_: XXCoder, considering the line of work i'm in...
09:15 PM _unreal_: THINGS that are rusted are in high supply
09:15 PM _unreal_: working on YACHTS :)
09:15 PM XXCoder: ah sal;t water air
09:16 PM _unreal_: There are a number of things i wached he could have done different and had much better results
09:16 PM XXCoder: yeah I dont assume "oh thats the best way" either
09:16 PM _unreal_: and NO it does NOT take high heat
09:17 PM _unreal_: right off the bad "he may not have one" but an ultrasonic bath would have solved a lot of issues
09:17 PM _unreal_: bad=bat
09:17 PM _unreal_: removed a lot of the rust scale
09:17 PM _unreal_: most parts would have falled apart
09:18 PM XXCoder: yeah that probably isnt something he has, never saw one once on his channel
09:18 PM XXCoder: its so cheap but usually too small for stuff he uses
09:18 PM _unreal_: night and day tool
09:18 PM _unreal_: TRUST ME
09:19 PM XXCoder: night and day? as in constant used?
09:19 PM _unreal_: as in the difference between what you see
09:19 PM _unreal_: see to finish
09:20 PM XXCoder: man wish I could get pocketnc for free lol
09:20 PM _unreal_: pocket cnc?
09:21 PM XXCoder: no I correctly spelled it
09:21 PM _unreal_: I'm sure you did I just dont know what it is
09:21 PM _unreal_: oh mini 5 axis
09:21 PM XXCoder: yeah
09:21 PM _unreal_: its only 3k
09:21 PM _unreal_: ;)
09:21 PM XXCoder: thats not "only 3k" to me lol
09:22 PM _unreal_: When I finish building this BIG cnc I could mill one
09:23 PM _unreal_: Thats whyI'm in the Marine industry... they $$$ pay well
09:23 PM XXCoder: i doubt they have room for mere operator/basic cnc machinist
09:24 PM _unreal_: cnc'ers are rare air
09:24 PM _unreal_: in the mainre
09:24 PM Tom_L: XXCoder how long you been at it?
09:24 PM XXCoder: cnc machinist? around 5 years now (both jobs counted) or 4.5 years if only current
09:24 PM _unreal_: infact the new welder they hired is TICKLED pink because I can DO cad work
09:24 PM Tom_L: XXCoder west coast?
09:25 PM Tom_L: should be plenty of cnc work out there
09:25 PM XXCoder: my orginal plan was to work 5 years then go to boeing but now...
09:25 PM Tom_L: there is here i know
09:25 PM _unreal_: the welder knows MORE about design then I do schooling wise but he CANT do shit when it comes to cad
09:25 PM XXCoder: boeing pay cuts and sucky health insurance
09:25 PM Tom_L: yup
09:25 PM Tom_L: they moved out of here
09:25 PM Tom_L: spirit bought them out
09:25 PM XXCoder: pay is still a big jump up BUT also means 30 min-hour drive one way everyday
09:26 PM _unreal_: does NOT pay to be in a blue state
09:26 PM XXCoder: my current job its 15 min
09:26 PM _unreal_: heh
09:26 PM XXCoder: _unreal_: im not sure what you mean, my pay is quite good
09:26 PM _unreal_: XXCoder, thats me
09:26 PM _unreal_: 1hr drive to and from
09:26 PM _unreal_: years ago when I worked for hinckleys www.hinkcleys.com
09:26 PM _unreal_: it was a 12min drive
09:27 PM _unreal_: www.hinckleys.com
09:27 PM XXCoder: nice. for me summer is like 30 min lol traffic so bad
09:27 PM XXCoder: but rest of year around 15 min
09:27 PM XXCoder: return home is very near always 12 min or so
09:27 PM _unreal_: no traffic its 30min for me
09:27 PM XXCoder: record on return home was 55 minutes lol
09:27 PM _unreal_: try 2 hours
09:27 PM XXCoder: my car was off for 35 min of that
09:28 PM XXCoder: cold and reading a book lol
09:28 PM _unreal_: never have to worry about cold MUAHAHHAAHAHAHAH
09:28 PM XXCoder: 2 hours heh my record for any return to home is 3 hours
09:28 PM _unreal_: heeh its 81F outside
09:28 PM XXCoder: 5 car accient
09:28 PM XXCoder: not same locatuon, all seperate
09:29 PM _unreal_: ouch google this "weather ellsworth maine"
09:29 PM XXCoder: one on highway to freeway, 3 on freeway, and final one on highway to home
09:29 PM _unreal_: heh
09:29 PM _unreal_: I see a hit and run at least 3-5 times a year
09:29 PM _unreal_: most of them are illegal aliens
09:30 PM XXCoder: meh google weather tacoma wa
09:30 PM _unreal_: burr
09:30 PM XXCoder: looks like one of rare freeze days
09:30 PM _unreal_: My brother lives in seattle
09:31 PM _unreal_: lol same temp there as where I use to live
09:31 PM XXCoder: cool :)
09:31 PM _unreal_: I dont miss the cold
09:31 PM _unreal_: at all
09:32 PM Tom_L: 45F Lo 35
09:32 PM XXCoder: I hate hot weather
09:32 PM _unreal_: cold weather gives me horrid dry cracked skin
09:32 PM _unreal_: lots of bleeds
09:32 PM _unreal_: I'm not kidding
09:33 PM _unreal_: hell I put on 30lbs just moving to florida with in the first year
09:33 PM _unreal_: 2013
09:33 PM flyback: https://pastebin.com/Qq3xAuWj
09:34 PM * Tom_L gives flyback a flux capacitor
09:34 PM XXCoder: oh that explains it.
09:35 PM XXCoder: saw big flyback branded drones parolling city here
09:35 PM XXCoder: glory be to flyback
09:36 PM XXCoder: _unreal_: btw https://www.youtube.com/watch?v=JfGHcyyjpmE very good
09:36 PM XXCoder: and I really want that tap thing
10:24 PM flyback: na no glory to be till I see data
10:25 PM XXCoder: lol
10:25 PM flyback: although a win3.1 disk showed up fine
10:25 PM flyback: it defintely does better than linux on really fucked up disks
10:25 PM flyback: it's still fucked up data
10:25 PM flyback: but you get some pieces
10:25 PM flyback: which is way more than I had before
10:41 PM _unreal_: time for bed
10:41 PM XXCoder: _unreal_: https://www.youtube.com/watch?v=t_egp4Hqc8Q
10:41 PM XXCoder: might like that more heh
10:42 PM XXCoder: I kinda want that tool hes constantly adverting about
10:42 PM XXCoder: its like better version of cercent wrench
10:59 PM XXCoder: i like how careful he is with unsafe materials. in least, more than average repair videos
