05:58 AM JT-Cave: morning
08:13 AM MrSunshine: yeey looks like the mesa card comes on friday, if nothing goes wrong .. now i need to read up on how to use these cards also :P
08:45 AM MrSunshine_ is now known as MrSunshine
08:55 AM unterhaus_: MrSunshine JT has a config tool that should help you get started
09:16 AM randy: the most important tool is IMHO mesaflash ;)
10:09 AM JT-Cave: my configuration tools all use mesaflash in several ways
10:14 AM -!- #linuxcnc mode set to +v by ChanServ
10:53 AM randy: JT-Cave: no offense :) i meant the very basic tool should be at least mesaflash + additional helper tools like yours
11:17 AM JT-Cave: really you only need mesaflash if the default firmware is not what you need and 99% of the time for cards like 7i96 etc the default firmware is fine
12:31 PM MrSunshine: JT-Cave, 7i92M is the card, i want to use it as an ordenary parport for a breakout board =)
12:59 PM JT-Cave: https://gnipsel.com/mesa/7i92/index.html
01:12 PM miss0r: JT-Cave: I did some test shooting. 15meter range, it puts the shots within an area of 1.5"X1.5" with 10 shots
01:13 PM miss0r: and that is not due to my hands shaking, this is in a vice mounted setup, so that is the gun accuracy. Not great if it were a real rifle, but this is not :)
01:14 PM Tom_L: you spin the projectile right?
01:14 PM Tom_L: put a point on it too
01:14 PM miss0r: I spin the projectile to aprox 20k rpm
01:15 PM unterhaus_: I can do better than that with a cd disc on a dremel :)
01:15 PM miss0r: it embeds itself in the wood stump I have the target mounted to, with no point on the projectile
01:15 PM Tom_L: video...
01:15 PM Tom_L: the point will make it slip thru the air cleaner
01:16 PM Tom_L: try a couple and see if it improves accuracy
01:16 PM miss0r: Tom_L: If I get the time I will make a video tomorrow. I seem to recall someone in here mentioning they could upload it for me, so it is not tied to me :D
01:16 PM Tom_L: i meant unterhaus_
01:16 PM Tom_L: but yeah
01:16 PM miss0r: I am still going to :)
01:16 PM Tom_L: jt can upload it
01:17 PM miss0r: I'll try the pointed end. But I doubt it will make alot of difference on a 15meter range
01:17 PM unterhaus_: no video because we shouldn't have been shooting cd's in the lab
01:17 PM miss0r: Keep in mind the barrel is 0.1mm larger than the projectile, so all the accuracy is generated by the centering of the metal in the magnetic fields
01:17 PM miss0r: unterhaus_: Poor excuse :)
01:18 PM unterhaus_: according to the internet it's easier to explode a cd than shoot it
01:19 PM miss0r: But the internet is a big'ol place..
02:25 PM t4nk_freenode: welllll... I decided to just drill the holes a bit bigger so the rods have some room
02:25 PM t4nk_freenode: another 32 drilling operations... haven't drilled my hand
02:25 PM t4nk_freenode: no burns
02:25 PM t4nk_freenode: but
02:26 PM t4nk_freenode: experienced a whole nother type of injury; bruised foot!
02:26 PM t4nk_freenode: lol
02:26 PM t4nk_freenode: see, the first few times the clams came loose and ejected forcefully onto my foot... were okay
02:26 PM t4nk_freenode: but I guess it happend a few times too many
02:27 PM t4nk_freenode: *clamps
02:34 PM t4nk_freenode: (I'm not gonna look btw, I bet it's like when a little kid spots his cut knee; I'd start to cry! ;) )
03:07 PM verm___ is now known as verm__
03:38 PM roycroft: i finished adding the thermocouple to my kiln at lunch today and have the kiln fully reassembled
03:39 PM roycroft: and it still gets hot after the work
03:39 PM roycroft: i should be able to assemble the pid controller this weekend, when the parts have arrived, and then it will be ready for precise temperature control
03:43 PM t4nk_freenode: *sigh* .. thinking about buying a welding machine again
03:43 PM t4nk_freenode: maybe this time I'll really get one
03:45 PM t4nk_freenode: https://www.lidl.nl/p/parkside-vuldraad-lasapparaat/p100342661
03:46 PM t4nk_freenode: doesn't seem too expensive
03:47 PM roycroft: i don't know if you can get everlast welders where you live, but they are very good, and very competitively priced here
03:47 PM roycroft: they are not as cheap as that, but they're much better quality
03:52 PM t4nk_freenode: yeah, I think I can get them perhaps.. heh, but more expensive indeed
03:52 PM t4nk_freenode: I mean.. 120euros .. that's not too much
03:53 PM t4nk_freenode: I've often thought about getting one, but never did
04:00 PM -!- #linuxcnc mode set to +v by ChanServ
04:03 PM roycroft: it's not going to be terribly useful
04:04 PM roycroft: it doesn't look like you can add shield gas to it, and at a glance it looks like it has current control but not wire speed control
04:05 PM -!- #linuxcnc mode set to +v by ChanServ
04:05 PM roycroft: esab are probably more available to you than everlast
04:05 PM roycroft: and are another low price but decent quality line

05:23 PM black-sqaure-til: I am trying to short two pins together to test a USB parallel port adapter. Can someone point out what to pins I should be shorting together?

05:31 PM t4nk_freenode: Tom_L, was that what you meant too btw, turn the edge of the beam up, and then have two bearings ride that edge?
05:32 PM Tom_L: turn the square 45deg yes
05:32 PM t4nk_freenode: anyhow, I just finished putting together the second carriage
05:32 PM Tom_L: lots of bearings
05:32 PM Tom_L: probably don't need near that many
05:32 PM t4nk_freenode: so I drilled the holes 10mm now, while the rods are 8mm...
05:33 PM t4nk_freenode: I guess it won't really matter
05:33 PM t4nk_freenode: yeah, lol, _lots_ of bearings
05:33 PM t4nk_freenode: and LOts of nuts too ;)
05:33 PM Tom_L: you'll realize that when it comes time to adjust it all
05:33 PM t4nk_freenode: it's completely nuts actually :))
05:34 PM t4nk_freenode: but that was another of my contemplations for not going with the c-beams.. I have so many bearings that would go unused
05:34 PM black-sqaure-til: Answered my own question. Pin 2 and pin 3. https://www.aggsoft.com/rs232-pinout-cable/images/X24-pinout.gif
05:35 PM t4nk_freenode: I know that I probably won't need as many as I have on now, but since I'm just playing around, it's acutally kind of fun
05:35 PM t4nk_freenode: and it looks and feels pretty sweet too
05:36 PM t4nk_freenode: I also decided not to cut the 40x30mm beam in half, but keep the meter
05:36 PM t4nk_freenode: and buy two more
05:36 PM t4nk_freenode: go with the larger size
05:36 PM t4nk_freenode: and meanwhile use some 30x30 beams I have on my smaller machine
05:36 PM XXCoder: when will we invent self-trimming grass?
05:39 PM t4nk_freenode: anyhow, Tom_L, the way I see it, riding the edge like that would exert a lot of force on a very small area
05:39 PM t4nk_freenode: leading to lots of wear
05:39 PM t4nk_freenode: now I have like 3487 bearings to catch the force ;)
05:40 PM Tom_L: you need 2 more
05:40 PM t4nk_freenode: :)
05:40 PM t4nk_freenode: I'm on to it straightaway :))
05:48 PM Tom_L: http://ruemohr.org/~ircjunk/projects/cnc6/p1130045.jpg
05:51 PM t4nk_freenode: ouch
05:51 PM t4nk_freenode: that is nasty ;)
05:54 PM Tom_L: not going for accuracy
05:55 PM Tom_L: 4' x 8' bed iirc
05:56 PM t4nk_freenode: mmm... I think this guy is actually pretty adept
05:56 PM t4nk_freenode: and got some nice tools, big lathe too
05:56 PM Tom_L: he is
05:57 PM t4nk_freenode: and how about this: http://ruemohr.org/~ircjunk/projects/cnc6/p1130059.jpg
05:57 PM t4nk_freenode: that looks suspiciously like cast alu
05:57 PM Tom_L: it is
05:57 PM Tom_L: for a brace for the cnc
05:57 PM Tom_L: he's getting better at casting
05:57 PM Tom_L: i've known him for quite a few years
06:07 PM monkey-wrench-so: Tom_L thanks for the IRC logs.
06:08 PM monkey-wrench-so: I have installed linuxcnc using http://www.linuxcnc.org/iso/linuxcnc-2.8.2-buster.iso
06:09 PM monkey-wrench-so: When I try to install a program like emacs or minicom it does not work.
06:09 PM monkey-wrench-so: The error message is "E: Package 'emacs' has no installation candidate".
06:21 PM Tom_L: https://gnipsel.com/linuxcnc/uspace/debian10-rt.html
06:21 PM Tom_L: another way to do it
06:36 PM monkey-wrench-so: I installed minicom with dpkg.
06:37 PM monkey-wrench-so: I have the pins shorted to test the serial port USB adapter.
06:38 PM monkey-wrench-so: How can I find the tty number to set for minicom?
06:38 PM monkey-wrench-so: For the USB parallel port adapter.
06:40 PM Tom_L: are you using a usb adapter for linuxcnc?
06:40 PM Tom_L: it WILL NOT work
06:46 PM monkey-wrench-so: Tom_L yes I amĀ  just trying to test a USB parallel port adapter just to see if I can get the x, y and z axies to jog based on the pinout information I have found with help from others here.
06:47 PM Tom_L: ok but don't plan to use it because USB isn't realtime
06:49 PM monkey-wrench-so: Tom_L okay it is just to see if I can get the machine to jog the axies.
06:49 PM monkey-wrench-so: I am trying to tip to the parallel port and have it echo back on the screen.
06:50 PM monkey-wrench-so: dmesg says "new full-speed USB device number 5 using ehci-pci" when i connect the adapter.
06:51 PM monkey-wrench-so: lsusb says "Bus 004 Device 005: ID 2121:2130"
06:51 PM monkey-wrench-so: So I have tried /dev/tty5
06:52 PM monkey-wrench-so: with `sudoi minicom -s`
06:52 PM monkey-wrench-so: `sudo minicom -s`
06:53 PM monkey-wrench-so: How should I try echoing what I type to minicom through the adapter.
07:04 PM t4nk_freenode: is that all that dmesg shows?
07:04 PM t4nk_freenode: how did you get to tty5
07:07 PM monkey-wrench-so: t4nk_freenode it was dmesg -w
07:08 PM t4nk_freenode: you should probably see another device registering and attaching to something like ttyUSB0 or so
07:09 PM Tom_L: what does lsusb show
07:12 PM t4nk_freenode: https://linux-hardware.org/?id=usb:2121-2130
07:12 PM t4nk_freenode: Device 'www.planet-cnc.com CNC USB Controller'
07:12 PM monkey-wrench-so: lsusb shows "Bus 004 Device 005: ID 2121:2130" is the device when I plug it in.
07:14 PM monkey-wrench-so: t4nk_freenode yes it is the planet-cnc.com one.
07:15 PM monkey-wrench-so: The work shop is closing. I have to leave the computer. I will read the IRC log when later.
07:15 PM t4nk_freenode: Question: Can the USB CNC Controller be used with LinuxCNC?
07:15 PM t4nk_freenode: Current Solution
07:15 PM t4nk_freenode: The USB Interface can only be used with the Planet-CNC software which runs under the windows operating system.
07:16 PM monkey-wrench-so: t4nk_freenode okay thank you
07:16 PM t4nk_freenode: not sure because I don't have one, but I think it may not work in linux
07:16 PM monkey-wrench-so: I will look at getting a PCI express parallel port to plug into the desktop computers PCI express slot.
07:17 PM monkey-wrench-so: I will also look at getting a parallel to parallel cable.
07:19 PM monkey-wrench-so: Thanks for the help going away from the computer.
07:21 PM _unreal_: I love planet cnc
07:21 PM _unreal_: I have a controller board sitting right in front of me
07:22 PM _unreal_: usb-cnc-9-axis
07:34 PM t4nk_freenode: does that work in linux?
07:48 PM t4nk_freenode: [02:06:00] <_unreal_> usb-cnc-9-axis
07:48 PM t4nk_freenode: [02:19:29] <t4nk_freenode> does that work in linux?
10:51 PM acer is now known as _unreal_
10:51 PM _unreal_: t4nk_freenode, yes there is a linux version for planetcnc go to there web site
