12:48 AM Cromaglious_: OK, working on filming installing cnc fusion
12:59 AM pink_vampire: CaptHindsight: link?
01:46 AM justan0theruser is now known as justanotheruser
01:56 AM Deejay: moin
01:56 AM gloops: hello
02:12 AM pink_vampire: hi Deejay gloops
02:17 AM gloops: right, try and sort this config today
02:19 AM gloops: between other stuff
02:25 AM pink_vampire: what are you trying to do?
02:26 AM gloops: two motor on 1 axis
02:26 AM gloops: JDSoft SurfMill 7.0 < this looks good
02:27 AM pink_vampire: mmm
02:27 AM pink_vampire: i'm not sure how to do it
02:29 AM gloops: i know how its done, its just doing it heh, theres a step by step tutorial on the forum, ive got basic hal and ini files to load, just got to add home switch pins and set homing up, probably half an hours work on a good day, i couldnt concentrate on it yesterday
02:29 AM pink_vampire: i'm about 2 days jut cleaning here
02:30 AM pink_vampire: same here
02:30 AM pink_vampire: i feel like i don't have energy
02:32 AM pink_vampire: gloops: don't feel bad, i took me almost half a year to do the configuration for linux cnc
02:41 AM gloops: lol it wont take that long
02:41 AM gloops: what machine was that for?
02:42 AM pink_vampire: 3 axis lpt G0704
02:44 AM gloops: well, it should be easy with the stuff im working with, just basic chinese stuff, it is easy, i just havent done it yet
02:44 AM pink_vampire: i need to find a place for my sandblast box
02:44 AM pink_vampire: the hardest part was the buttons on the screen
02:44 AM gloops: had a dodgy pin issue yesterday that used my time up, actually i think it might have been a noise issue pin 15 is bang next to ground
02:45 AM gloops: ive got most of next week anyway
02:45 AM gloops: pink_vampire can understand it being complex for that kind of machine/electricals
02:46 AM pink_vampire: i have more then 20 probing scripts
02:47 AM gloops: well, i might get onto the harder stuff eventually, the priority atm is to get this thing moving and making, and tidy the garage up heh
02:49 AM pink_vampire: I want to add 4th axis or servo spindle, but all the time i just enjoy cutting and modify stuff by manual jogging and mdi commands
02:51 AM pink_vampire: the most favorite command is "g0 x[#5420/2]" it is basically move the X axis to whatever on the X axis dro divide to 2
02:52 AM pink_vampire: it is sooo easy to find centers this way.
02:52 AM pink_vampire: gloops: ^
02:52 AM gloops: hmm thats a good method
02:54 AM pink_vampire: also, i you need to drill bunch of hole in the same distance you can use that, "g0 X[5420+30]"
02:54 AM pink_vampire: and run the same line each time you want to jump to the next hole.
02:54 AM gloops: all this i have yet to learn about
02:55 AM pink_vampire: what do you mean?
02:55 AM gloops: first machine was not adequate so stopped cutting and started making another one, never progressed much with g code
02:56 AM pink_vampire: mmm i see what you mean.
02:56 AM gloops: spent more time building than actually doing anything with a machine - no previous experience
02:58 AM pink_vampire: but in my case, I'm using the machine as a "proper" cnc machine with Gcode generated from HSMWORKS and it is work beautiful, but some time I just need to modify something, or drill a hole, and fore stuff like that, the MDI is much faster to use
02:58 AM gloops: yes see what you mean, tbh probably fewer cases like that with wood
02:59 AM pink_vampire: I don't like wood
02:59 AM pink_vampire: too much dust
03:00 AM gloops: this is good modelling https://scontent.fman1-2.fna.fbcdn.net/v/t1.0-9/27544620_10215431985102789_3079863647556524702_n.jpg?oh=0b66d3531ffd0161f6bc1fc983792db7&oe=5ADBFA89
03:00 AM pink_vampire: WOW
03:01 AM pink_vampire: it's more then 12H job...
03:01 AM gloops: cant see much of the machine but could be diy https://yadi.sk/i/17Ni_sA4ywK9X
03:01 AM gloops: he did make that model, looks sound finished
03:02 AM pink_vampire: seams like a diy machine
03:02 AM gloops: wonder what he charged for that job
03:03 AM pink_vampire: arm and leg
03:08 AM gloops: right off i go, no internet on garage pc
03:09 AM pink_vampire: why?
03:09 AM pink_vampire: use wifi
03:27 AM gloops: got wifi usb but not installed it yet, cd came with it - no wifi on old box
03:29 AM pink_vampire: just run a cable
03:30 AM gloops: i will soon
03:31 AM gloops: got files loading again anyway, trouble is i did several configs to test different parts, i have to have all the files open at once and try to splice the bits into one hal file haha, gets confusing
03:36 AM archivist: gloops, install meld on the pc that highlights the differences then you can move stuff file to file
03:36 AM pink_vampire: can you share your screen?
03:36 AM gloops: not without saving it and bringing it to this one
03:36 AM archivist: can compare three files at the same time
03:37 AM gloops: yeah, you just have to be careful you arent editing one of the working files and not the one youre making
03:37 AM gloops: anyway do a bit more
03:54 AM IchGucksLive: hi
03:54 AM IchGucksLive: ice rain here in germany
03:54 AM IchGucksLive: gloops: first mill ?
03:55 AM IchGucksLive: or even a bit brek
03:56 AM pink_vampire: hi
03:56 AM pink_vampire: i have a problem with my sand blast glass
03:56 AM IchGucksLive: ;-)
03:56 AM IchGucksLive: take a new one
03:57 AM pink_vampire: the glass is fine
03:57 AM IchGucksLive: i use thick tape for shielding
03:57 AM pink_vampire: it just get static that make all the dust stick to it
03:58 AM IchGucksLive: oh you need to hevy grond the system
03:58 AM IchGucksLive: you can get up to 6000V and 0,02A out of it
03:58 AM IchGucksLive: it might kill you
03:59 AM IchGucksLive: on blasting ALoy
03:59 AM pink_vampire: it is plastic
04:07 AM jthornton: morning
04:07 AM pink_vampire: hi jthornton
04:08 AM gloops: well thats the hal file https://justpaste.it/1gjq2
04:08 AM gloops: im wondering, do the pins need to be allocated in the same order as the joints?
04:08 AM gloops: getting wierd results from this
04:09 AM gloops: x moves 1 x motor, y moves other x motor, z moves y
04:09 AM pink_vampire: you get an error?
04:09 AM gloops: no it loads
04:10 AM gloops: the pins are set in hal to correspond with the right pins on the board for each motor
04:10 AM jthornton: gloops: https://paste.ubuntu.com/ your ini file
04:12 AM gloops: https://paste.ubuntu.com/26504939/
04:14 AM gloops: ive got the joints out of order on the pins, so like x is pin 2/3 y is 4/5 xo is 6/7
04:14 AM gloops: dont know if that makes any difference
04:15 AM gloops: so joint 0, joint 2, joint 1
04:20 AM jthornton: is joint 0 and 1 the gantry and have you homed it
04:21 AM gloops: yes 0,1 the gantry, no not set up homing yet
04:22 AM jthornton: until you home you can only move joints IIRC
04:23 AM gloops: on the linuxcnc screen, the jog buttons x moves first motor, y moves second x motor, z moves y
04:23 AM jthornton: Are you using Axis?
04:24 AM gloops: yeah
04:24 AM jthornton: on the manual control tab does it say Joint 0 1 2 3 or Axis: X Y Z?
04:25 AM gloops: xyz...ahh
04:25 AM TurBoss: hello
04:25 AM jthornton: ok something is not right
04:25 AM gloops: yes i did see joint 0123 on an early attempt, months ago, ill read some more
04:26 AM gloops: i have pasted hal and ini files into an xyz config
04:26 AM pink_vampire: i need irobot in my life
04:26 AM jthornton: your missing HOME_SEQUENCE from the ini http://linuxcnc.org/docs/devel/html/config/ini-homing.html#_home_sequence
04:27 AM jthornton: without home sequence it is just a 4 axis machine
04:27 AM jthornton: I think
04:28 AM jthornton: and you need kinstype=BOTH
04:30 AM jthornton: gloops: create the Axis gantry sim and look at the ini file after you run it
04:30 AM gloops: ok thanks, ill return to it later and check those, needs homing setting yp anyway
04:30 AM gloops: is that a twin motor gantry?
04:30 AM jthornton: yes
04:31 AM gloops: right that would be a big help to see a working gantry file
04:31 AM jthornton: when you boot up on the manual tab it should say Joint: 0 1 2 3
04:31 AM gloops: im doing this is half hour bits and bobs which doesnt help, ill do the gantry sim first and look at it
04:31 AM jthornton: KINEMATICS = trivkins coordinates=XYZY kinstype=BOTH
04:32 AM jthornton: your missing the last bit on that line
04:32 AM jthornton: line 30 in your ini file
04:32 AM gloops: yeah thats completely missing
04:32 AM gloops: ill sort that
04:33 AM gloops: bbiab
04:46 AM XXCoder: hey all
04:48 AM pink_vampire: hi XXCoder
04:48 AM XXCoder: whats up
04:49 AM pink_vampire: I'm cleaning
04:54 AM gloops: jthornton kinstype=BOTH has brought up joints not xyz - working in correct sequence now, will look at homing later
04:56 AM XXCoder: fun cleaning
04:56 AM XXCoder: today I ran fiberglass parts ugh
04:56 AM XXCoder: hate em
04:57 AM jthornton: gloops: that is a good sign
05:31 AM TurBoss: hello XXCoder
05:31 AM XXCoder: yo
05:32 AM TurBoss: managed to reasemble a ball nut :P
05:32 AM TurBoss: hehe
05:32 AM TurBoss: noticed that there are 2 separated ball circuits
05:35 AM Tom_L: 17°F
05:35 AM Tom_L: https://www.youtube.com/watch?v=GtFTRyS__Yc
05:36 AM XXCoder: you need dual dial inidctor thing
05:38 AM Tom_L: buy me one
05:38 AM XXCoder: sure it... now in mail
05:38 AM pink_vampire: no nee for dual
05:38 AM pink_vampire: one is all you need
05:38 AM XXCoder: tom honestly think it can be made
05:39 AM XXCoder: just need a reliable way to make sure they line up.
05:39 AM XXCoder: and china has $10 dials
05:39 AM pink_vampire: XXCoder: there is no need for that
05:39 AM Tom_L: i'll leave that to Mr Starrett
05:39 AM pink_vampire: single dial is just fine
05:39 AM jthornton: 18°F
05:40 AM Tom_L: guess we both got it
05:40 AM XXCoder: pre-spring very heavy rains here
05:40 AM pink_vampire: i'm next to the heater
05:40 AM XXCoder: river quite high
05:40 AM XXCoder: basement still very dry thanks to sump pump
05:41 AM SpeedEvil: yay
05:41 AM jthornton: where does it pump the water to?
05:41 AM XXCoder: yard
05:41 AM XXCoder: it has 30 feet long hose, then large tank with top overflow in case it fails to despese of water
05:42 AM XXCoder: funny thing its been so busy that concerete havent dried 100% yet after a week. need more fans blowing on em fopr it to cure
05:43 AM jthornton: new concrete not dry after a week?
05:43 AM XXCoder: its 80% there now, some isnt done yet
05:44 AM jthornton: it's cured but not dry?
05:44 AM XXCoder: no, 80% areas is cured and dry
05:44 AM XXCoder: 20% still need more assistance to finish
05:44 AM jthornton: concrete will cure under water
05:45 AM XXCoder: odd
05:46 AM XXCoder: well in any case most is solid gray, some is dark gray
05:46 AM XXCoder: felt solid but dunno
05:48 AM archivist: it is a chemical reaction not "drying"
05:48 AM XXCoder: well they used special blowers on em
05:48 AM XXCoder: so dunno lol
05:49 AM XXCoder: and yes I know its a chemical reaction
05:50 AM archivist: keep it above a certain temperature probably
05:50 AM gloops: is there a membrane underneth it?
05:50 AM XXCoder: hmm thats likely actually
05:50 AM XXCoder: gloops: yeah in order to keep dirt and concerete away from rocks and hoses
05:51 AM XXCoder: arch my bro's room heater is on and going, but its still pretty cold downstairs since main heater is still removed.
05:51 AM gloops: well, it will pull moisture from the ground - forever if it isnt sealed with dpc membrane, could be still be damp from laying
05:51 AM archivist: they also use dehumidifiers to remove the water
05:52 AM gloops: its actually better to keep it wet with water during curing, for a harder set
05:52 AM XXCoder: its very dry downstairs, at 40% humidity now. my room is at 56%. nicer now than when downstairs was wet, my room was ranging at dangerous 70% to 80%
05:58 AM XXCoder: in least it is going pretty well. need to finish stuff so my bro have nice place to sleep in.
05:58 AM XXCoder: its very unfair to my bro :(
07:10 AM IchGucksLive: hi
07:11 AM XXCoder: hey iced over
07:13 AM IchGucksLive: only thick snowflakes right now
07:13 AM IchGucksLive: so maybe soon power fail if powerlines fail out here in the forest
07:14 AM IchGucksLive: cake baking big party this wekend
07:15 AM IchGucksLive: carnaval
07:15 AM XXCoder: 50f all week, doubt will snow unless feb gets cold lol
07:18 AM IchGucksLive: today spain got overcoverd in snow never seen that bevor
07:18 AM IchGucksLive: as snowfall deep into africa Marocco
07:23 AM IchGucksLive: cake smees out of the oven i need to lower temp
07:23 AM IchGucksLive: im off till later BYE
08:58 AM d3z1b3l: hi thogeter is anybody here? ;-)
08:58 AM d3z1b3l: I'm here the first time
09:10 AM JT-Shop: 147 "here", how many are looking at the channel is unknown
09:32 AM gloops: howdy
09:33 AM gloops: slow progress with this config, i can now get homing set up just be editing hal and ini, ..i think, its all good learning
09:41 AM gloops: net home-x => joint.*.home-sw-in < in this line does => denote the direction the axis will search for the switch?
09:41 AM gloops: ini file
09:42 AM gloops: no, hal
09:43 AM gloops: or is that the direction of the signal out> or in<
09:44 AM pcw_home: that just connects the signal (wire) home-x to joint.*.home-sw-in
09:45 AM pcw_home: the => is just for readability ( its ignored by the hal parser )
09:46 AM pcw_home: you can leave it out (or reverse its direction ) and you will get the same results
09:46 AM gloops: ahh ok
09:47 AM gloops: i just copied a few lines from a config with working homing, and its searching the wrong way thats all, ill probably spot what it needs
09:48 AM gloops: i think it needs - for search velocity maybe
09:48 AM pcw_home: hal knows which pins are inputs and outputs so the => is not needed
09:48 AM gloops: ok thanks i can stop contemplating that then
09:48 AM Connor: yea those are for human readability.
09:49 AM gloops: reverse sign of search velocity should change direction
09:58 AM JT-Shop: gloops: http://linuxcnc.org/docs/devel/html/config/ini-homing.html#_homing_sequence
10:00 AM Jymmm: Um.... ZAP!!!! https://i.imgur.com/DMyJ51n.gifv
10:00 AM gloops: hey, just had first kind of movement with 2 motors together, need to sort out homing sequence and direction thats all
10:02 AM JT-Shop: your getting there
10:02 AM JT-Shop: to answer my question from the other day yes you can cut AR400 with a bandsaw
10:24 AM d3z1b3l: Hallo Zusammen, ich habe ein IBM Thinkpad 2668. Pentium M 1.86 GHz 2GB Arbeitsspeicher Auf linuxcnc.org habe ich das Live Image heruntergeladen und auf dem Laptop installiert. Ich konnte meine Maschine unter Linuxcnc gut einrichten und sie lauft auch. Jedoch habe ich 2 Probleme: 1) Hin und wieder bleibt das Programm Linuxcnc einfach hängen, dann geht garnichts mehr. 2) fast immer kommt folgende Fehlermeldung: "RTAPI: ERROR: Un
10:25 AM d3z1b3l: Hat Jemande einen Tipp?
10:25 AM cradek: your error got cut off after RTAPI:ERROR because your message was too long
10:28 AM MarkusBec: d3z1b3l: english ist hier zu bevorzugen
10:39 AM JT-Shop: d3z1b3l: use paste.ubuntu.com for error messages
10:44 AM MarkusBec: pcw_home: is it possible to connect the THC to a smart serial device ?
10:45 AM gloops: well will leave the playing for today, pulleys on motors slipping, 2 screws and a flat on shaft, need to look at those
10:54 AM roycroft: my router bit will arrive tomorrow, hopefully
10:54 AM roycroft: it's made it to portland
10:54 AM roycroft: i've been working on other stuff but i really need to do the work with that bit this weekend
10:55 AM * roycroft is still hoping to complete the router table this month
10:59 AM d3z1b3l: sorry, The Error is: RTAPI: ERROR: Unexpected realtime delay on task 1. This Message will only display once per session. Run the Latency Test and resolve before continuing.
10:59 AM d3z1b3l: Latency test shows a value of approx. 6000 at idle. I've tested all sorts of configuration values, no change.
11:00 AM MarkusBec: d3z1b3l: 6000 is never ever you latency
11:01 AM MarkusBec: d3z1b3l: you have to run it for longer
11:01 AM MarkusBec: opening a browser watch a movie on youtube
11:01 AM MarkusBec: or start some glxgears
11:02 AM MarkusBec: s/or/and
11:02 AM d3z1b3l: ahh, ok, i will test it! in a youtube video somebody showed it for short time
11:02 AM MarkusBec: you have to find you max value
11:02 AM MarkusBec: r
11:03 AM d3z1b3l: but i already put 70000 to the configuration, same problem, can it be too big?
11:03 AM d3z1b3l: i tried many different values
11:04 AM MarkusBec: i think the hw can be to outdated
11:04 AM MarkusBec: to run the os and linuxcnc
11:05 AM pcw_home: MarkusBec: probably better to use a 7I87 in that case
11:06 AM MarkusBec: is every IO isolated?
11:06 AM pcw_home: yes
11:06 AM MarkusBec: i want it as a remote unit in a big plasmacutter
11:06 AM MarkusBec: to sense arc voltage and current
11:07 AM Connor: Freaking MSC.. Local branch is sales office only.. Still ship to you.. WTF is that.. how stupid..
11:10 AM d3z1b3l: @ MarkusBec: Now i whatched a 720p youtube video. It works not fluent but it works. My Jitter is no at 554311
11:10 AM MarkusBec: pcw_home: is there anything like 2-3 adc channels and 8 IO imputs ?
11:10 AM d3z1b3l: should i set 60000?
11:10 AM MarkusBec: you can test this
11:11 AM MarkusBec: but i think its not a nice HW for a cnc mashine
11:11 AM d3z1b3l: ok, so i can look for a better pc :-)
11:12 AM cradek: d3z1b3l: very few laptops have acceptable realtime performance. try any old desktop board you have handy.
11:13 AM cradek: d3z1b3l: latency of 550000 is at least 10x too bad to use
11:13 AM cradek: d3z1b3l: a usable machine will look more like 20000
11:14 AM d3z1b3l: In a Forum i read, that somebody installed a light version of linux and installed the cnc software manually so it works on old laptops. do you know something about it? or is it no good way?
11:14 AM MarkusBec: d3z1b3l: at the moment i am using a 100€ dell i7
11:14 AM MarkusBec: with 4gb ram
11:15 AM MarkusBec: d3z1b3l: these kind of hardware is finaly for the scrap bin
11:15 AM cradek: d3z1b3l: I don't think that will help you. it's a hardware problem, not anything you can affect with software changes
11:16 AM d3z1b3l: ok, than i will buy another PC, no Problem. Is your Dell good? can you tell me wich one exactly?
11:16 AM d3z1b3l: i prefer a Laptop because i have not so much space
11:17 AM d3z1b3l: thank you cradek!
11:17 AM roycroft: you will probably have issues trying to run a real time kernel on a laptop and having it keep up with the needs of your cnc machine
11:17 AM pcw_home: Even laptops that have decent latency most of the time have specific power management traps that cannot be disabled
11:17 AM roycroft: oh, i see cradek said that already
11:18 AM roycroft: never mind :)
11:18 AM MarkusBec: d3z1b3l: https://www.itsco.de/pc-dell-optiplex-3010-dt-intel-core-i3-3240-2x-3-4ghz-21055.html
11:18 AM roycroft: there are a couple approaches to getting a desktop machine to use for linuxcnc
11:18 AM MarkusBec: but i have a i7
11:19 AM roycroft: one is to buy a system board that is known to work well with linuxcnc
11:19 AM pcw_home: ( on my E6420 I can have days of ~30 usec latency if I never change the backlight brightness or change from battery to line power )
11:19 AM roycroft: another is to buy a random system board and see how well it works, and try a different one if it doesn't
11:20 AM roycroft: a third is to buy whatever you want, install a mesa board in it, and not have to worry about latency issues
11:20 AM roycroft: so i guess that's not a couple approaches, but three
11:21 AM roycroft: i don't consider buying something random, seeing if it will work, and repeating that until something works as a realistic approach though
11:21 AM roycroft: so i'd go with #1 or #3
11:21 AM miss0r: I wonder for how long one of those continues rotation RC-servos can run for without having to cool off for a while
11:26 AM d3z1b3l: @MarkusBec: Your PC got no Parallelport, do you have a Card in it?
11:27 AM MarkusBec: first pcie to parallel
11:27 AM MarkusBec: now a second networkcard with a mesa fpga card
11:29 AM MarkusBec: mesa 7I92 Ethernet Anything I/O card
11:30 AM MarkusBec: d3z1b3l: where are you from?
11:30 AM d3z1b3l: Near Ingolstadt, you?
11:32 AM gloops: to change from units in INCH to MM what needs changing
11:34 AM cradek: gloops: are you sure you don't want to just add a G21 in your gcode
11:34 AM MarkusBec: frankfurt
11:36 AM d3z1b3l: ah, not so near ;-) would you agree to a short telephone call?
11:36 AM gloops: cradek well id rather start with mm, i made a basic config and pasted edited hal and ini files into it, only the edited files were done in an inch config
11:37 AM gloops: i could start out again and make all new files with mm
11:38 AM gloops: steppers are not moving any near relative to speeds and distance linuxcnc moves, changing SCALE etc makes no difference
11:38 AM MarkusBec: d3z1b3l: wir können gern im query schreiben aber telefonieren ist hier eher schwirig
11:52 AM IchGucksLive: hi
11:56 AM gloops: hi
11:57 AM IchGucksLive: pcw_home: ?
11:57 AM IchGucksLive: gloops: mashine milling parts
11:58 AM gloops: you are milling parts Ichs?
11:59 AM IchGucksLive: d3z1b3l Still online
11:59 AM gloops: ive had the 2 motor axis moving, but very very slow, made stupid mistake of using an INCH config
11:59 AM IchGucksLive: d3z1b3l_ Still online
11:59 AM gloops: going to start again
12:00 PM IchGucksLive: gloops: that even makes you more powerfull
12:00 PM gloops: i mean slow like 1 inch per hour heh
12:00 PM gloops: something messed up
12:00 PM IchGucksLive: best to go for good sleep mill
12:01 PM IchGucksLive: gloops: you taked on 400ipm
12:01 PM IchGucksLive: now you are on mm
12:01 PM gloops: yes on other configs it is hitting good speeds, just this 2 motor one
12:01 PM gloops: that is the problem i think, ive mixed inch and mm
12:02 PM gloops: maybe tommorrow sort it out
12:02 PM IchGucksLive: do you reealy need this gantry homing i found best to see if there is trouble on manuell control
12:02 PM IchGucksLive: i got on the FOAM 2 dials
12:02 PM gloops: it is trying to home, but as i say - moving very very slow
12:03 PM gloops: i am learning about it as i go though, almost there
12:03 PM IchGucksLive: d3z1b3l d3z1b3l_ ich bin in Zweibrücken
12:04 PM IchGucksLive: pcw_mesa: ?
12:09 PM pcw_home: you rang?
12:10 PM IchGucksLive: pcw_home: the eu surplus is out of stock on 7i92
12:11 PM IchGucksLive: what do you recomend to buy at Europ#
12:13 PM gloops: i might glue these pulleys to motor shaft
12:13 PM IchGucksLive: make a hard tight steel fix
12:14 PM gloops: slipping with 2 screws in
12:14 PM gloops: unless i put 4 screws in maybe
12:14 PM IchGucksLive: matching feather
12:14 PM IchGucksLive: its a big work but it realy pays off
12:14 PM gloops: what do you mean?
12:15 PM IchGucksLive: i did it with only XY runing
12:15 PM IchGucksLive: and on Estlcam torancial
12:15 PM IchGucksLive: you will get also good relaults
12:15 PM gloops: matching feather?
12:16 PM IchGucksLive: gloops: http://www.bdat-hauschildt.de/arc/zubehoer5-1.php
12:16 PM IchGucksLive: yes
12:16 PM gloops: ahh like a key
12:16 PM IchGucksLive: the steppers shafts are not that hard
12:16 PM IchGucksLive: with co8
12:17 PM IchGucksLive: 3mm bit 4mm feader
12:17 PM gloops: awkard to hold though
12:18 PM IchGucksLive: gloops: you may find a shop in your near that has -> https://www.paulimot.de/raeumnadeln-sets/707/raeumnadel-set-fuer-2-3-und-4-mm-keilnuten
12:19 PM pcw_home: IchGucksLive: we dont have any 7I92s either ATM but have plenty of 7I92Ms
12:19 PM IchGucksLive: pcw_home: but it will be a coustom service nightmare from USA
12:20 PM MarkusBec: pcw_home: with the plasma is it possible to have a combined input outbut with analog
12:20 PM MarkusBec: i want only 1 small cable to connect the plasma to the rest
12:21 PM IchGucksLive: MarkusBec: warum nimmst du keine standardthc
12:21 PM MarkusBec: was verstehst du darunter
12:21 PM IchGucksLive: updown arc ok
12:22 PM IchGucksLive: ich habe da ein 4x0,25 dazwischen
12:22 PM MarkusBec: würde gern brenn spannung und strom am pc messen können
12:22 PM IchGucksLive: und zum plasma 2x0,5
12:22 PM MarkusBec: remote
12:23 PM MarkusBec: also der plasma trafo wiegt halt auch 2,5t hat 150A anschlussleistung und ich will da net lange daneben stehen :)
12:24 PM IchGucksLive: die spannung vird auf 10m nicht wesentlich fallen
12:25 PM fragalot: hi
12:27 PM IchGucksLive: fragalot: ;-)
12:31 PM gloops: ill be a hal master by the time ive dones this haha
12:32 PM pcw_mesa: MarkusBec Yeah ideally we would have a sserial device specifically made for plasma
12:32 PM pcw_mesa: with a couple A-D channels and some digital I/O, plus a RS-485 port to set plasma current
12:32 PM pcw_mesa: in my spare time :-)
12:33 PM MarkusBec: :)
12:47 PM IchGucksLive: d3z1b3l_: online ?
01:06 PM IchGucksLive: im off Gn8
01:18 PM jesseg: Hmmmm.. Placing an onlinemetals.com order, what else should I get "while I'm at it."
01:19 PM gloops: is that the UK online metals?
01:22 PM jesseg: I use the USA one, not sure about any others
01:23 PM jesseg: but it's totally great. They even cut metal to size for you.
01:23 PM gloops: ahh ok, yeah there are similar outlets here, what are you getting ally?
01:23 PM Tom_L: gloops how's it goin?
01:24 PM gloops: Tom-L not got it running properly yet, still messing with 2 motor 1 axis config, have had both motors moving together and trying to home though
01:24 PM jesseg: gloops, yeah right now getting some 1/8" & 1/4" al plate and 2x2" 1/4" thick angle al
01:25 PM jesseg: in past got al round, brass round, copper round, and 99% pure nickle round.
01:25 PM Tom_L: running 2.8?
01:25 PM jesseg: You want to talk about something that's evil to machine with a wimpy flexible machine. 99% nickle will fit the bill.
01:26 PM gloops: yeah, not far off with it now i dont think, not been getting too much time on it, im just re-doing hal and ini files now, try again tommorrow
01:26 PM Tom_L: got my head trammed last night
01:27 PM Tom_L: picked up some coolant today
01:27 PM gloops: this should be the last time consuming bit of mine, rest is pretty straightforward hopefully
01:27 PM gloops: youll be going before me haha
01:27 PM Tom_L: you see the tram video?
01:28 PM gloops: no not seen that one, not been looking that much today
01:28 PM gloops: jesseg is it a router youre making?
01:28 PM Tom_L: https://www.youtube.com/watch?v=GtFTRyS__Yc
01:29 PM gloops: that would do for me Tom heh
01:29 PM Tom_L: close enough for me
01:30 PM Tom_L: need to find some more polycarbonate to put around the table now
01:30 PM Tom_L: kinda help keep the chips contained
01:31 PM gloops: thats not bad to say its a diy machine, youd be lucky to get that with a lot of purpose built machines
01:31 PM Tom_L: all i had was some scrap and cardboard: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Chip_Guard2.jpg
01:31 PM Tom_L: i'll fix it up a bit later
01:33 PM gloops: thats something you can do when the right material comes handy or whatever
01:33 PM Tom_L: yep
01:34 PM Tom_L: the paper was stuck to some of it so i just left it for now instead of spending hours trying to peel it of
01:37 PM gloops: will do the job for now
01:38 PM gloops: memory card on my hone is duff, made a vid of my machine homing the y axis on camera - cant find lead to upload it now, ill make some when new card for phone arrives
01:43 PM jesseg: gloops, 3D printer, although it would be suitable for milling styrofoam and perhaps clay or wax. https://openbuilds.com/builds/easy-to-build-and-robust-3d-printer-framework.2359/
01:52 PM jesseg: but it's sort of large format, about 400x400x500mm
01:54 PM gloops: that is a fair size yeah
01:57 PM miss0r: Don't you just love it, when the most noisy part of machining is the chips hitting the plexiglass enclosure? :D
02:05 PM gloops: chips hitting anything would be a fine thing atm!
02:11 PM MarkusBec: pcw_mesa: is it possible to use the encoder inputs of the 7I73 with the thc
02:12 PM MarkusBec: The HostMot2 encoder counter firmware is capable of measuring input frequency. The HostMot2 drivers velocity output is proportional to the input frequency and can be used to read out the THCADs analog input voltage.
02:28 PM pcw_mesa: Its possible but the velocity estimation is only counts/sample since there is no timestamp in the 7I73 encoder
02:29 PM phipli: hum
02:29 PM pcw_mesa: It could probably be done with a 7I90 but like the 7I73 its not isolated
02:29 PM phipli: does anyone understand load capacitors on oscillators?
02:30 PM Tom_L: phipli what about them?
02:30 PM Tom_L: you should use what the data sheet recomends for that particular crystal
02:30 PM phipli: looking at the various ceramic resonators, they mostly seem to have built in caps
02:30 PM phipli: but you can get ones with different value capacitance
02:31 PM Tom_L: alot of them do
02:31 PM phipli: the chip example circuit has a regular crystal and 2x 22pF caps
02:31 PM phipli: the crystals themselves have a capacitance if I understand correctly
02:32 PM phipli: a) do I match the total system capacitance to the normal crystal circuit...
02:32 PM phipli: b) if there isn't an exact match, do I go up or down!
02:32 PM CaptHindsight: b) yes
02:32 PM Tom_L: you should be able to find caps for the crystal you're using
02:32 PM Tom_L: c) none of the above
02:32 PM CaptHindsight: phipli: have a part number?
02:33 PM phipli: looking at things like (but not specifically) https://uk.rs-online.com/web/p/ceramic-resonators/7214805/
02:33 PM MarkusBec: pcw_mesa: isolation is a fixable problem
02:33 PM phipli: to go with a ch340g
02:33 PM phipli: usb chip
02:34 PM Tom_L: you don't need any with that one
02:34 PM Tom_L: if it's like the one i posted for you
02:34 PM phipli: it has internal caps, but don't I need to get the capacitance right?
02:34 PM CaptHindsight: Featuring built in load capacitance, these SMD ceramic resonators eliminate the need for external load capacitors
02:34 PM Tom_L: ^^
02:35 PM Tom_L: just solder and go
02:35 PM phipli: but there are variations of the part, with different capacitors
02:35 PM phipli: (built in)
02:36 PM CaptHindsight: http://docs-europe.electrocomponents.com/webdocs/0ef2/0900766b80ef2ca9.pdf data sheet for the series
02:37 PM gloops: has the debugger been improved for 2.8? seems very specific now, cant say i noticed it was in 2.7
02:39 PM CaptHindsight: " The X2 is 12MHz quartz crystal, C6 and C7 are monolithic or high frequency stoneware capacitance with 22pF. If X2 is ceramic with low cost, C6 and C7 must use the recommend value of crystal manufacturer and generally is 47pF."
02:40 PM CaptHindsight: https://cdn.sparkfun.com/datasheets/Dev/Arduino/Other/CH340DS1.PDF
02:41 PM phipli: interesting
02:41 PM phipli: that is high in the available range...
02:41 PM phipli: the highest option on the datasheet
02:43 PM CaptHindsight: I see a 33pf version
02:43 PM phipli: ditto
02:43 PM phipli: datasheet says 47pF exists, but can't see it for sale
02:44 PM phipli: (where I'm looking at least)
02:44 PM phipli: at 25p each I'll get some and see what happens
02:44 PM gloops: ini for 2 motors 1 axis, using axis and joints in 2.8 https://justpaste.it/1gkjs
02:45 PM CaptHindsight: https://uk.rs-online.com/web/p/ceramic-resonators/7214809/
02:45 PM CaptHindsight: CSTCE12M0G55-R0, Ceramic Resonator, 12MHz Fundamental 33pF, 3-Pin Cap Chip, 3.2 x 1.3 x 0.7mm
02:45 PM phipli: yeah - thats what I'm looking at
02:45 PM CaptHindsight: you can also add external caps
02:46 PM phipli: makes sense
02:46 PM CaptHindsight: I don't know the internal details of the internal oscillator ...
02:46 PM fragalot: 'sup
02:46 PM CaptHindsight: but you can always have pads there and not use them
02:46 PM gloops: and the hal https://justpaste.it/1gkjv, loads ok, i dont think im far off now, made some tweaks from files that had 2 motors moving and trying to home earlier
02:47 PM CaptHindsight: try the 33pf version, watch it over temp
02:47 PM phipli: excuse to play with the thermal camera at work
02:50 PM CaptHindsight: what do other CH340G boards use for xtals?
02:50 PM phipli: good idea - I'll check some schematics
02:50 PM MarkusBec: pcw_mesa: what does the sserial FW do with the 7i90
02:51 PM CaptHindsight: if you really want to be sure use an external oscillator :)
02:51 PM pcw_mesa: its just GPIO now
02:51 PM MarkusBec: ah hm ok
02:51 PM pcw_mesa: but it could be any Hostmot2 function
02:51 PM MarkusBec: not that usefull :)
02:51 PM MarkusBec: ok
02:52 PM MarkusBec: its spartan 3 based?
02:53 PM pcw_mesa: No, SP6
02:54 PM MarkusBec: oh ok thats nicer less complicated to setup the toolchain :)
02:55 PM MarkusBec: ust filling up a harddrive
02:55 PM MarkusBec: j
03:12 PM JT-Shop: damn hard facing rods are nasty
03:14 PM fragalot: smokey, spattery or does the bead look like crap?
03:25 PM gloops: i wonder id a stepper motor shaft could take a tack on the end, while shaft is in situ
03:25 PM fragalot: I wouldn't do that
03:25 PM fragalot: the heat would most certainly warp it
03:26 PM gloops: well, people say they arent hard, a normal drill bit wasnt making much headway when i tried drilling them
03:26 PM fragalot: does anyone have a source for decent quality carbide hand-scraper blades?
03:27 PM gloops: grub screws arent reliable
03:27 PM fragalot: I dropped mine and it's in a thousand bits :(
03:28 PM gloops: use hss
03:28 PM Skullworks: frag - that took skilz
03:28 PM fragalot: Skullworks: it really didn't
03:29 PM fragalot: gloops: find me HSS scraper inserts then -- I used to use a 300mm long 16mm HSS blank but that's just awful
03:30 PM Skullworks: I've hit one just right such that the skin of the carbide was still silver soldiered in place but what looked like the entire piece came out.
03:30 PM gloops: there were some good links posted during a discussion of scraping one night, not got the logs, was ages ago anyway
03:31 PM gloops: https://www.ebay.co.uk/itm/Bahco-BAH625PEAR-625-PEAR-Carbide-Edged-Scraper-Blade-/161050875878?
03:31 PM gloops: bahco are decent
03:32 PM gloops: actually i think thats a paint scraper lol
03:32 PM fragalot: it is
03:33 PM fragalot: can't find what size that is, but judging from the hole it's not that big
03:33 PM fragalot: not enough to grind a usable radius on it anyway
03:35 PM gloops: not much comes up, stuff like this https://www.ebay.co.uk/p/Faithfull-FAIEHSF8-Engineers-Hand-Scraper-200mm-8in-Flat/1926367288?
03:35 PM fragalot: i'm not wasting my money on faithful
03:35 PM fragalot: the fact that brands like that exist hurt my soul
03:36 PM gloops: https://www.ebay.co.uk/itm/Vintage-Moore-And-Wright-Scraper-Set-Engineers-Tools-VGC-Best-On-Ebay/273035086743?
03:36 PM gloops: faithful is pure crap yes, its a disgrace to the brand that was
03:37 PM gloops: look for bearing scrapers
03:38 PM gloops: https://www.ebay.co.uk/itm/VINTAGE-LARGE-ENGINEERS-CARBIDE-TIPPED-BEARING-SCRAPER-18-VINTAGE-TOOLS/382368890269?
03:39 PM fragalot: all I really need is the little insert
03:42 PM gloops: theyll sell carbide blanks, ive bought fairly sizeable hss blanks before, 10 inch long 2 inch wide
03:43 PM fragalot: I can't seem to find a source for flat carbide blanks
03:43 PM fragalot: square I can find, but that's cumbersome
03:46 PM fragalot: sandvik 620 scraper holders everywhere but can't find the blades
03:50 PM Skullworks: frag - are you in the UK?
03:50 PM fragalot: no, but close
03:52 PM Skullworks: There is a company in the US - Manhatten supply aka MSC MSCdirect.com they stock a full asortment of blades for the Sandvik 620
03:54 PM CaptHindsight: is that what the M stands for!
03:54 PM Skullworks: We call them the Big Book because the catalog is hardbound and about 115mm thick.
03:54 PM * skunkworks didn't know that either...
03:54 PM gloops: https://www.ebay.co.uk/itm/X2-TUNGSTEN-CARBIDE-SQUARE-TOOL-BIT-CNC-LATHE-BLANK-CARBIDE-9-50mmx9-70mmx30-5mm/222438791084?
03:54 PM skunkworks: they bought out enco - then the prices went up
03:55 PM gloops: he has got different sizes but i aint looking through his shop
03:55 PM fragalot: 'are you in the UK because I have this good supplier from the US' :P
03:55 PM CaptHindsight: why did I think it was Mutual Sales Corp?
03:55 PM fragalot: CaptHindsight: Merciless*
03:55 PM gloops: english tungsten carbide not the foreign rubbish
03:55 PM Skullworks: Yup - and every time I do a customer survey I bitch about it and tell them to re-open the enco division.
03:56 PM fragalot: gloops: I might just braze a parting tool onto a scrap piece & use that
03:57 PM gloops: that will work
03:57 PM gloops: i fancy some of these vintage scrapers though
03:57 PM gloops: not that id ever use them for much
03:59 PM CaptHindsight: Zoro tools has the HQ nearby but nothing comes from there
03:59 PM CaptHindsight: it's always days from the west coast
04:00 PM CaptHindsight: and Zoro is a division of Grainger
04:01 PM gloops: in a link that was posted on here, a bloke showed all about scraping, and how to make a scraper, there is a pretty common item that uses bits of carbide that are ideal, i cant remember what it was now
04:02 PM fragalot: gloops: let me know if you can remember!
04:05 PM gloops: i doubt ill remember lol
04:06 PM enleth: what would be the most proper and elegant way of retaining an extension sleeve that fits onto a keyed motor shaft?
04:07 PM CaptHindsight: Surface Scraping, 1940's https://www.youtube.com/watch?v=k4lUmE945js how gandpa did it
04:07 PM CaptHindsight: grandpa even
04:07 PM enleth: https://hackerspace.pl/~enleth/extender-v3.pdf - this is what I have so far, the motor shaft comes in from the top, two holes in the sleeve wall are for screws that would engage threaded holes in the key to both prevent the key from sliding out, and the sleeve from sliding off
04:07 PM enleth: but it feels somewhat inelegant
04:08 PM enleth: with the screws sticking out the side
04:08 PM gloops: CaptHindsight on quality lathes like mine, circa 1920, the scraping is left rough, to retain oil
04:08 PM Rab: enleth, how about an exquisitely machined collet?
04:08 PM Deejay: gn8
04:08 PM gloops: they also left the rest of the lathe rough
04:09 PM enleth: Rab: let's consider frugality to be an aspect of elegance for a moment, then it's not a terribly elegant solution
04:09 PM CaptHindsight: enleth: looks fine, maybe a little thin at the wall of the inside keyway
04:10 PM gloops: drill the end of the shaft and tap it - retaining bolt
04:12 PM CaptHindsight: how fast will that spindle go?
04:13 PM enleth: CaptHindsight: maybe up to 6krpm if I'm feeling lucky. more like up to 4-4.5krpm
04:13 PM Rab: enleth, drill and tap the shaft with access holes in the opposite side of the extender. The set screws push outward against the key, not inward.
04:14 PM CaptHindsight: 38mm outer dia, hhm wondering about balancing that for 6krpm
04:14 PM fragalot: gloops: the scraping is not "left rough"
04:14 PM fragalot: gloops: the scraping is intentionally flaked.
04:14 PM enleth: Rab: interesting idea
04:15 PM gloops: fragalot to the laymens eye it might be considered rough
04:15 PM fragalot: gloops: eg. they scrape it as normal (eg. over 20 points of contact per square inch), and then gauge it with a flaking tool
04:15 PM fragalot: you can normally recognize the flaking as they look like little tick marks
04:16 PM enleth: in case anyone asks why is the hole and the keyway all the way through - I don't have access to anything that could broach an internal keyway in a blind hole, but I can have the keyway cut on a wire EDM
04:16 PM gloops: its easy to think that having variation in the surface height would cause the peaks to wear down at a faster rate, but the oil trapped in the lows actually reduces wear
04:17 PM fragalot: gloops: the oil gets trapped and you start to get a hydraulic bearing surface
04:17 PM gloops: yes linear oil bearing
04:20 PM gloops: you can also use that to check for wear on an old machine
04:21 PM Rab: enleth, I think it might be most proper and elegant, and maybe prudent, to increase the diameter of the extender so it can fully contain the screws. That keyway doesn't leave much material; one good stall or impact and it might crack.
04:25 PM enleth: Rab: I intend to use a soft, 120mm long key, wouldn't that help spread the load of an impact quite a bit? I realized there is going to be *a* point of contact at first until the key flexes/gets deformed into contacting the sleeve at its full length, but it seems kinda adequate
04:26 PM enleth: but I can widen it to 40 or 42mm and still be within the 1610 taperlock size range
04:26 PM enleth: I'd have to widen the outer keyway to 12mm though, 40 and 42mm taperlock sleeves have 12mm keyways
04:27 PM enleth: I kind of wanted to keep the number of different key sizes in a single transmission stage to a reasonable minimum
04:28 PM enleth: not a very important metric, I know
04:29 PM Rab: enleth, I can't say what's safe, I'm offering a gut estimate rather than an engineering opinion.
04:29 PM Rab: Have you considered making your own, longer taper lock bushing?
04:30 PM enleth: fuck no
04:30 PM enleth: have you *seen* the half-threads on the locking holes?
04:31 PM enleth: I have a rough idea of how it might be manufactured, but I'm pretty sure I don't want to be trying that
04:31 PM Rab: Yeah, seems like that would be accomplished by tapping a round and turning until the threads are exposed.
04:31 PM enleth: maybe as a project
04:31 PM enleth: not as an intermediate stage in getting a machine working ASAP
04:31 PM Rab: OK, shaft extension is looking pretty reasonable.
04:32 PM fragalot: Rab: or by thread milling.. saves a lot of material when manufacturing thousands of those
04:32 PM Rab: fragalot, definitely.
04:32 PM fragalot: and it's easier to clock them all the same
04:33 PM Rab: enleth, you could cosmetically hide the screws in locking collars. Widen the holes in the extension to clearance. https://static.grainger.com/rp/s/is/image/Grainger/36WX89_AS01
04:35 PM Rab: However that introduces more material which might be slightly excentric and consequently imbalanced...not sure that qualifies as elegant or proper.
04:36 PM gloops: https://scontent.fman1-2.fna.fbcdn.net/v/t1.0-9/27332522_10215442172717473_3333797826772120848_n.jpg?oh=377df5c6cbc6f97ccf9bebd563b82a41&oe=5B1F94F3
04:38 PM gloops: (staircase actually looks a bit rough but the cnc carving is nice)
04:41 PM enleth: oh, one chance I can make that will definitely make this stronger is to round off the inner corners of the internal keyway
04:41 PM enleth: then chamfer one side of the key
04:41 PM enleth: *change
04:44 PM gloops: i have only just realised what happens with a gantry using joints, by using the sim
04:44 PM gloops: and i cannot believe the ini and hal files for that are in the linuxcnc folder haha
04:45 PM pink_vampire: hi
04:46 PM gloops: hello
04:50 PM phipli: hum. just bought 5000 capacitors
04:50 PM phipli: because at £5 for 5000, I'll never need to buy any again
04:50 PM JT-Shop: an assortment?
04:51 PM phipli: sorry, correction, I meant resistors
04:51 PM phipli: no, I got 5000 10k resistors
04:51 PM phipli: for all my pull-up needs forever
04:51 PM JT-Shop: for a long time
04:51 PM phipli: I doubt I could ever use 5000
04:52 PM phipli: if I do, I'll have to through a no more resistance party or something
04:53 PM fragalot: what size are they
04:53 PM phipli: 0805
04:53 PM fragalot: about half of them are going to get lost anyway so it's fine
04:53 PM phipli: lol
04:53 PM phipli: true
04:53 PM phipli: never work with them when you have a cold
04:54 PM fragalot: I bought a reel of 0204's by accident once
04:54 PM phipli: how did you know if they arrived?
04:54 PM Rab: I bought reels of 0805, and then almost immediately moved to 0603. :P
04:54 PM fragalot: phipli: you get a reel
04:54 PM fragalot: and hwen you peel the reel open
04:54 PM phipli: at that size you could probably accidentally inhale the reel :)
04:54 PM fragalot: you lose 90%
04:54 PM fragalot: the plastic just goes "pop" the tiniest bit, and the resistors are gone
04:55 PM fragalot: especially fun if you're using multiple values, lol
04:55 PM phipli: fragalot, : note to self - open them under water to reduce velocity
04:55 PM fragalot: so you sort them into SMD boxes
04:55 PM fragalot: which you then drop
04:55 PM fragalot: and they all mix
04:55 PM phipli: I've been snipping off as many as I need and not doing anything else until I'm just about to use them
04:56 PM fragalot: "was this a 0ohm bridge, or was it an inductor?"
04:56 PM phipli: past experience tells me my elbow is very good at putting them onto the floor
04:56 PM phipli: yeah, my stupid 0805 caps aren't labelled
04:56 PM phipli: once they're out, they're a mystery
04:56 PM phipli: I'd have to build a capacitance meter
04:57 PM fragalot: haha
04:59 PM Rab: phipli, get this! It really works and it's worth every penny! https://smile.amazon.com/dp/B00F3RQCFW/
05:00 PM phipli: :)
05:00 PM phipli: I was considering building something like that
05:00 PM phipli: cutting up a pair of tweezers or something
05:01 PM fragalot: I've got one of those chinese LRC ones with a modified tweezer
05:01 PM fragalot: gets me in the ballpark
05:01 PM phipli: probably more accurate than the label from what I hear with some of the capacitors :)
05:01 PM fragalot: $3 sensor with $30 tweezers, lol
05:02 PM JT-Shop: I'll be so glad when this machine build is done... it's wearing me out
05:03 PM gloops: what are you making JT?
05:03 PM phipli: how is it going?
05:04 PM JT-Shop: starting to make some headway with it
05:04 PM JT-Shop: hope to finish the drum part in a few days
05:04 PM JT-Shop: gloops: making an inline cleaner for nails
05:05 PM gloops: i saw the drum, didnt know what it was going to be part of
05:05 PM JT-Shop: finally got the exit transition to work like I want
05:05 PM gloops: a cleaner for nails? like nails that get knocked into wood?
05:05 PM JT-Shop: machine quality nails for pallet making machines
05:06 PM gloops: ahh right
05:07 PM JT-Shop: a few more photos http://gnipsel.com/images/cleaning-line/
05:08 PM * phipli hehs
05:09 PM gloops: all looks very pro and tidy
05:10 PM JT-Shop: that's a fault I have I'm very particular about my work
05:11 PM fragalot: JT-Shop: I like the shop inspector in pic 2
05:12 PM phipli: :)
05:12 PM phipli: can't believe you let them in the shop JT
05:13 PM phipli: is that Henry's "dog house"?
05:13 PM phipli: surprised he isn't behaving yet, or do you not have the motor fitted?
05:18 PM Tom_L: how come some refractometers are twenty bux and some are 300?
05:19 PM JT-Shop: no still working on the drum part
05:19 PM phipli: postage prices?
05:19 PM fragalot: same reason for anything to have a variation in price
05:19 PM fragalot: Tom_L: also - neat job tramming the head :)
05:19 PM Tom_L: thanks
05:20 PM Skullworks: Quality glass vrs plastic
05:20 PM Tom_L: are they specialized for certain things or pretty much all the same just better quality?
05:20 PM Tom_L: i see some for salinity
05:20 PM fragalot: specialized
05:20 PM fragalot: I have an el cheapo saline one for my pond
05:20 PM Tom_L: not interchangeable?
05:20 PM fragalot: no
05:21 PM Skullworks: yup - there is one for beer brewers
05:21 PM JT-Shop: fragalot: that is my favorite photo
05:21 PM Tom_L: i don't think i'll worry about it too much, i'm gonna use it for mist coolant anyway
05:21 PM fragalot: so buy a coolant one :P
05:21 PM Tom_L: i was gonna but nobody had one locally
05:22 PM Tom_L: i did get a jug of coolant though
05:22 PM fragalot: if all you'll use it for is the mister, you don't really need the refractometer
05:22 PM Tom_L: if i were worried about evaporation i may be more inclined to get one
05:23 PM fragalot: refractometers are more for checking flood coolant over time
05:23 PM Skullworks: ?me mist coolant is me sitting there with a spray pump bottle.
05:23 PM Tom_L: ^^
05:23 PM Tom_L: i'm a lazy bas....
05:23 PM fragalot: Skullworks: and an air hose - an important component of mist coolers
05:24 PM Tom_L: i wanna see if it goes thru the tube better than the oil i tried
05:24 PM Tom_L: i'm sure it will
05:24 PM Skullworks: build a fog buster type - trust me you will be glad you did. Vapor Mist sucks!
05:25 PM Skullworks: gets all over everything and leaves a sticky film
05:25 PM Tom_L: https://www.ebay.com/itm/Mist-Coolant-Lubrication-Spray-System-For-8mm-Air-Pipe-CNC-Lathe-Mill-DrillATBD/202151085390?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3Db6060eb396244e76880c9ad89ad7da5e%26pid%3D100675%26rk%3D3%26rkt%3D15%26sd%3D222351368210%26itm%3D202151085390&_trksid=p2481888.c100675.m4236&_trkparms=pageci%253A3215f7fc-0870-11e8-967e-74dbd1807a7a%257Cparentrq%253A58d5c6401610a9c454e02e3cfffe6f9d%257Ci
05:25 PM fragalot: lubrication is optional anyway with the right tooling & toolpaths :P
05:26 PM fragalot: I'm off - ttyl
05:26 PM Tom_L: i'm using it right now just to clear the material
05:27 PM Skullworks: good for killing cochroaches but it will really make a mess in your shop.
05:27 PM Tom_L: i'm not gonna use it 24/7 anyway
05:27 PM Tom_L: and i've got a 10" exhaust duct right above it if i need it
05:28 PM Skullworks: only takes 20 minutes to fog up a 30x120 shop
05:28 PM Skullworks: a few mods though and it will work like a charm
05:29 PM JT-Shop: you can do the same thing using hard facing rods
05:30 PM Tom_L: drill the orfice out more?
05:32 PM Skullworks: https://www.machinistblog.com/zero-fog-mister/
05:41 PM * evilroot is debating on which spindle to buy
05:45 PM JT-Shop: say goodnight Gracie
05:54 PM phipli: hum
05:55 PM phipli: If I just want to nab a domain and am not too interested in hosting a site there or anything. (email might be interesting though). What would be the best/cheapest way of doing so?
05:56 PM evilroot: godaddy
05:57 PM evilroot: They'll host your e-mail too for an extra buck or two
05:57 PM Skullworks: 1 email
05:57 PM Skullworks: I cursed the day I chose Godaddy as a host
05:58 PM evilroot: Meh, I never had any problem with them
05:58 PM phipli: that is kind of going for the full thing, rather than just grabbing a domain
05:58 PM phipli: Skullworks, is that "1 email" as a company? I can't see them in a google search
06:00 PM Skullworks: When you host a domain with them they include 1 catch all email - so anyhting mailed to @domain.com will end up in that email account. Additional filtered emails are a cost plus add on.
06:01 PM evilroot: But yeah, any suggestions on a spindle motor and VFD?
06:01 PM evilroot: I'm thinking 1500w
06:01 PM Skullworks: RPM range?
06:01 PM phipli: I have my current stuff all with one.com (might be the same company?)
06:02 PM phipli: I use the catch all email thing all the time
06:02 PM phipli: make up a new email address every time I sign up for something
06:02 PM Skullworks: Aah 7PM EST - I can close the doors on the helpdesk....:)
06:03 PM Tom_L: evilroot, i was thinking about something like this for mine: https://www.ebay.com/itm/ER20-Power-Head-Spindle-Unit-3000-6000rpm-Flange-60-80mm-fr-CNC-Drilling-Milling/201712741437?_trkparms=aid%3D555019%26algo%3DPL.BANDIT%26ao%3D1%26asc%3D20150817211623%26meid%3Dbf527327d18f48d3a0b4a91b8331c2a7%26pid%3D100505%26rk%3D1%26rkt%3D1%26%26itm%3D201712741437&_trksid=p2045573.c100505.m3226
06:03 PM Tom_L: not necessarily that one but similar
06:06 PM phipli: anyhow
06:06 PM phipli: night folks
06:06 PM Tom_L: later
06:07 PM Skullworks: Tom - what is the application
06:07 PM Tom_L: for my homebuilt mill
06:08 PM Skullworks: Then I would get the BT30 version
06:08 PM Tom_L: what's the max capacity for a ER20?
06:08 PM Tom_L: like 8mm tools?
06:09 PM Tom_L: or a little more?
06:09 PM Skullworks: I think its 5/8 `6mm
06:09 PM Skullworks: 16mm
06:10 PM Tom_L: https://www.ebay.com/itm/Drilling-Milling-Head-BT30-Spindle-7-24-Taper-3000rpm-5Barings-CNC-Machine-E/112772984847?hash=item1a41cb300f:m:mhnzc0y0owfQL2ZLegWHH0A
06:10 PM Tom_L: that was another one i saw
06:13 PM Skullworks: on ER20 is .512" or about 13mm
06:14 PM Tom_L: that's enough for this little mill anyway i think
06:14 PM Tom_L: https://www.ebay.com/itm/CNC-9KW-220-380V-ATC-Spindle-Motor-ISO30-BT30-China-HSD-Spindle-11KW-VFD-1000Hz/122359169694?hash=item1c7d2cc29e:m:mgrV0XBEyniyxIrf9Et5Ztg
06:14 PM Skullworks: are you mounting this on an existing machine?
06:14 PM Tom_L: yeah
06:15 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Mister1.jpg
06:15 PM Tom_L: using my old sherline head for now
06:16 PM Skullworks: 9Kw is over 9HP
06:16 PM Tom_L: :)
06:17 PM Skullworks: my Hurco CNC mill is 3HP with a 2.2Kw motor
06:18 PM Tom_L: i just happened to see that
06:19 PM Skullworks: One key factor to success with CNC is being able to use cost effective tools
06:19 PM Tom_L: right
06:19 PM Skullworks: so you want to be able to use 3/4" shank (19mm) tools
06:20 PM Skullworks: a best buy is a 3/8 carbide em because they don't have to reduce the body - less grinding
06:21 PM Tom_L: for that little one i've got up to 1/4" carbide
06:21 PM Skullworks: most insert tools start with 3/4" shanks
06:21 PM Tom_L: we ran some 3" and larger insert drills on some parts
06:21 PM Skullworks: but you keep the body and just toss the worn insert.
06:22 PM Tom_L: so i'm a little familiar with tooling
06:22 PM Skullworks: OK
06:22 PM Tom_L: mostly iscar or valenite
06:22 PM Tom_L: those were used on some TI landing gear struts
06:23 PM Skullworks: 6Al4V?
06:23 PM Tom_L: i don't remember now
06:23 PM Tom_L: that's been quite a while back
06:24 PM Tom_L: i do know the first articles were from solid billet
06:24 PM Skullworks: fun...
06:24 PM Tom_L: iirc citation 10
06:24 PM Tom_L: they tried using exhisting forgings but none they had were heavy enough
06:25 PM Tom_L: so they finally provided new forgings for us
06:26 PM fenugrec: Hi, just slightly off-topic here for a moment : what do people use to generate lathe toolpaths (2D) ? I've been using ProEngineer but I've just about had it with the arcane postprocessor and general crappiness (bugs and inconsistencies)
06:26 PM Tom_L: we did most of our lathe stuff MDI
06:26 PM Skullworks: Citation needs HD gear - t o handle all that weight of champeign bottles back in the galley
06:26 PM Tom_L: then saved it
06:26 PM fenugrec: I'm finding lots of free options for milling, but not so for turning
06:26 PM Tom_L: heh
06:28 PM Tom_L: fenugrec i've got an old version of smartcam lathe but i've only used it once or twice
06:28 PM Tom_L: non free..
06:28 PM Skullworks: not sure for 2d - I'd start using fusion 360 and see if there is a good post for your machine
06:28 PM fenugrec: Tom_L, yeah, I can do that too, but that gets old really fast on non-trivial parts !
06:28 PM Tom_L: JT-Shop may have written something
06:28 PM Tom_L: look on gnipsel dot com
06:28 PM Tom_L: he's got a lathe
06:28 PM Tom_L: i'm not sure..
06:29 PM fenugrec: Nobody has a PP for my machine, but I can deal with that if it's not completely mental like ProE's
06:30 PM Skullworks: I have a CNC turning center also - its 7800lbs helps keep the building from getting blown away - some day I will be able to pay for the wiring needed to power it up...
06:31 PM fenugrec: Skullworks, hehe, I know the type - probably big enough to rent the workspace as an appartment ?
06:32 PM Skullworks: not too bad, 12 tool turret, 8" chuck
06:33 PM Skullworks: needs 22KVA
06:33 PM Skullworks: 3ph
06:33 PM evilroot: Well I intend to be milling aluminum
06:33 PM fenugrec: Heh, my welder comes close - 100A breaker (@ 220V), but 1ph at least
06:33 PM evilroot: 1.5kw should do the trick
06:34 PM Skullworks: Big TiG unit?
06:34 PM fenugrec: Lack of OSS toolpath generation is a bit of a mystery to me - linuxCNC is a pretty healthy project, and way more complicated than just spitting out G code.
06:34 PM fenugrec: Skullworks, right. Miller dialarc something, old stick / HF start TIG
06:35 PM evilroot: And that ships from the US, heh
06:36 PM Skullworks: Nice - I been holding out on adding a TiG, have a 180 Mig with spoolgun that does AL and stainless.
06:36 PM fenugrec: ooh, Al spoolgun - I hear those can be finnicky and just not worth the hassle for hobby / low vol
06:36 PM Skullworks: Funny thing was I worked my way through College as a production welder
06:37 PM Skullworks: spools -must have clean work cause No HF.
06:38 PM fenugrec: I can say with confidence that HF doesn't mean you can get away with dirty workpieces : ))
06:38 PM evilroot: https://www.ebay.com/itm/1-5KW-AIR-COOLED-SPINDLE-MOTOR-80MM-ER16-CNC-220V-INVERTER-DRIVE-VFD/271910308524?_trkparms=aid%3D444000%26algo%3DSOI.DEFAULT%26ao%3D1%26asc%3D47301%26meid%3D90b8320b8ff64247a9cf954615109caa%26pid%3D100752%26rk%3D6%26rkt%3D6%26sd%3D282784612484%26itm%3D271910308524&_trksid=p2047675.c100752.m1982
06:38 PM evilroot: This seems decent
06:38 PM Skullworks: 1.5kw is almost perfect
06:41 PM fenugrec: so I gues just not that many people doing turning ops with linuxcnc ?
06:42 PM Skullworks: more like those who do tend to hand write there own programs
06:42 PM Skullworks: maybe you should use the Pathpilot port
06:43 PM Skullworks: its more like a fanuc type
06:44 PM fenugrec: hmm
06:44 PM evilroot: https://www.ebay.com/itm/4-BEARING-1-5KW-AIR-COOLED-SPINDLE-MOTOR-ER16-1-5KW-INVERTER-DRIVE-VFD-CNC/272998418207?hash=item3f8ff9471f:g:lt4AAOSwzXxZ~Ca3
06:44 PM evilroot: This seems decent too
06:48 PM Skullworks: I bought a SEIG X2 R8 Mill head and I may mount it on an extended router chassis. Still has the stock OEM 2 speed plastic geared head and 2200 rpm DC motor.
06:59 PM fenugrec: aaah, this will already help a lot if it works as seen on TV: https://forum.linuxcnc.org/41-guis/26550-lathe-macros
07:01 PM Tom_L: it should work
07:02 PM fenugrec: no doubt, but I have a pretty old install of linuxCNC (~2014), that might prove a problem
07:02 PM Tom_L: update it
07:02 PM Tom_L: i think i'm running 2.7 something
07:03 PM Tom_L: nothing on that should be that crazy
07:03 PM fenugrec: I should. I'd need to reinstall the whole thing, though ? IIRC it can't auto-update
07:03 PM Tom_L: i have a few times
07:03 PM Tom_L: what version?
07:04 PM evilroot: Also, any experieinces on PCIe parallel cards that work well with LinuxCNC?
07:04 PM fenugrec: computer is off (and downstairs), but it's based on Debian I think. An old release of the distro
07:04 PM fenugrec: 2.6.* maybe ?
07:05 PM Tom_L: i've updated from that with no issues
07:06 PM Tom_L: and andy's screen shows 2.6.0 if you didn't notice
07:06 PM fenugrec: Tom_L, hmm, I'll need to try then - did you do that through the system updater ? I mean it's not even the same distro "generation", I think the update URLs have change since
07:06 PM fenugrec: aaah nope didn't see that
07:06 PM Tom_L: yeah they changed servers
07:06 PM Tom_L: try it as is first
07:07 PM fenugrec: the lathe macros or the self-update ?
07:07 PM Tom_L: macros
07:08 PM fenugrec: right, will do. Otherwise I don't really need a full system update... "if it ain't broke"
07:08 PM Tom_L: xactly
07:09 PM fenugrec: I remember horrible problems when I first set up the machine due to one particular HDD model that caused huge amounts jitter, regardless of caching / PIO / UDMA settings. Wow, unpleasant memories
07:59 PM _fenugrec: So, just trying the lathe macros - none of them work, when I press "Go" linuxCNC pops up the red X error icon but with an empty message
08:04 PM _fenugrec: no message in the console either
08:11 PM _fenugrec: hmm it probably doesn't like sharing AXIS with pyvcp ?
10:05 PM Crom: how the heck did I get crap in the ball screw
10:22 PM Crom: About ready to tig on a extention to my X ball screw so I can run my stock handle
10:23 PM XXCoder: voodoo
10:23 PM XXCoder: as son as you look away, crap walks in
10:52 PM Crom: yep, now I'm going to have to take it apart and wash it
10:52 PM Connor: Don't loose any balls.. Crom
10:53 PM Crom: Conner yep, been there done that
10:53 PM Crom: Don't want another tshirt
10:53 PM XXCoder: loosened? just retighten your balls
10:53 PM XXCoder: just dont tighten it too much or you will go back to pre-dropped again and have to do puberity again
11:01 PM Crom: heh
11:10 PM Crom: weeeeeeee
11:13 PM pink_vampire: I love sand sandblasting!
11:17 PM XXCoder: yeah?
11:18 PM Tom_L: yeah it gets sand in every crack and crevice you can think of
11:19 PM pink_vampire: yes
11:19 PM pink_vampire: the cabinet is just sooooo good
11:20 PM pink_vampire: ZERO dust in the house
