[00:21:58] <rue_house> so, in G2, the I and J params are relative to the start location?
[00:22:51] <Jymmm> rue_house:
http://linuxcnc.org/docs/devel/html/gcode/g-code.html#gcode:g2-g3
[00:25:23] <rue_house> ok wait a sec, to do an arc or 45 degrees, you dont use g2/g3 ?
[00:25:51] <rue_house> ooh, click
[00:28:10] <rue_house> thanks
[05:23:59] <jthornton> morning
[05:24:45] <XXCoder> hey jt man
[05:38:11] <jthornton> what's up today?
[05:39:45] <XXCoder> not much
[05:39:49] <XXCoder> oh yea
[05:39:55] <XXCoder> rememebr the dead stepper I had?
[05:43:10] <jthornton> no, which one died
[05:43:53] <XXCoder> oh one that arrievd DOA
[05:44:27] <XXCoder> anyway I cut out the bad sections of wires. still refused to work
[05:44:36] <XXCoder> so I checked countunity
[05:44:49] <XXCoder> found out green wire was dead, and traced it to connector itself
[05:45:11] <XXCoder> so I ripped it out and did a bad hack repair job on it, its supposed to last maybe couple tests while I test it anyway
[05:45:21] <XXCoder> it worked perfectly.
[05:50:36] <jthornton> cool you got it to work
[05:50:36] <zhivko> good morning all
[05:50:46] <zhivko> midday here otherwise ;)
[05:51:03] <jthornton> I printed a cover for my ramps board last night... wonder how it came out?
[05:51:18] <jthornton> still dark here
[05:51:30] <XXCoder> it was fine whole time really
[05:51:40] <XXCoder> just messed up wiring
[05:51:55] <XXCoder> it also means I has extra stepper for extruder heh
[05:52:26] <zhivko> cradek: I try experimenting with feed calculation for g93.
[05:52:57] <jthornton> I'm glad I had the extra ramps board lol
[05:53:29] <zhivko> is there a way to see what joint or axis is getting to max limits in invere time mode for g01 ?
[05:53:40] <zhivko> inverse (g93)
[05:54:29] <zhivko> i am trying hylcmd show pin, but it seem all joints are way below max limits set in ini file
[05:55:08] <zhivko> i am trying hylcmd show pin, but it seem all joint speedsare way below max velocity limits set in ini file
[05:55:23] <zhivko> I am looking at them with: halcmd show pin hpg.stepgen.*.velocity-fb
[05:56:46] <zhivko> actually with: watch -n 1 halcmd show pin hpg.stepgen.*.velocity-fb
[05:56:48] <jthornton> you might use halscope
[05:57:14] <zhivko> what pins I need to chart there?
[05:57:23] <zhivko> is velocity-fb correct one?
[05:58:41] <jthornton> that should work
[05:58:48] <zhivko> is it part of tp where this actual velocities are calculated?
[05:59:35] <zhivko> it is funny because I am raising up feed for g01 move - and it seems velocity stays same... so it must hitting some max limits
[05:59:50] <zhivko> maybe you know in what piece of code is this calculating ?
[06:02:43] <zhivko> Are ou guys able to open this:
[06:02:45] <zhivko> http://jmkasunich.com/pics/emc2-motion-dataflow.pdf
[06:04:29] <jthornton> what version of LinuxCNC are you using?
[06:05:33] <zhivko1> hi... changed my network maybe now I could open this pdf..
[06:06:10] <zhivko1> JThornton: I use machinekit
[06:06:25] <zhivko1> JThornton: its fork of linuxcnc
[06:06:33] <jthornton> we have no idea then it is different
[06:06:47] <jthornton> yes I know about machinekit
[06:06:51] <zhivko1> this part should be same
[06:07:11] <jthornton> should could maybe maybe not
[06:07:12] <zhivko1> its just upgraded linuxcnc with protobufs and zmq
[06:07:18] <jthornton> we have no idea
[06:08:04] <zhivko1> I know its much easier to say that - but if we are talking in the term of lcnc... where this speeds in coordinated move would be calculated? I mean wich piece of code?
[06:08:16] <jthornton> I can't even remember when it was forked off
[06:08:39] <Jymmm> Best to talk with machinekit folks
[06:08:42] <zhivko1> OK :) I am not asking when it was forked... I am asking for coordinated move...
[06:08:50] <zhivko1> common guys
[06:09:04] <zhivko1> everytime same story :(
[06:10:34] <Jymmm> Only THEY know what they did/didn't do, go ask them. How hard is that?
[06:11:08] <jthornton> we don't know what has been changed so we don't have any ideas about machinekit
[06:11:16] <jthornton> ask Michael
[06:11:27] <Jymmm> It's like going into debian and asking about ubuntu.
[06:11:46] <jthornton> I don't have any velocity problems with LinuxCNC 2.7.x
[06:11:57] <jthornton> and my plasma goes 600IPM
[06:12:10] <zhivko1> sorry to ask I hope I could get lcnc response...
[06:12:39] <zhivko1> jthornton: you have workpiece that is still, and mine is rotating...
[06:13:24] <jthornton> well maybe the rotating axis can't go fast enough
[06:13:45] <Jymmm> zhivko1: How is the device connected to your computer?
[06:13:45] <zhivko1> I raised maxvel for A and B
[06:14:01] <zhivko1> device? what device?
[06:14:16] <Jymmm> zhivko1: or machine, or whatever you are controlling
[06:14:28] <zhivko1> I have simulator - running on BBB where linuxcnc is running... and then remote PC comunicating to BBB
[06:15:09] <zhivko1> I am reading positions over tcp/ip (beaglebone is actually USB connected to pc) - I am in bed right now - its better for my back....
[06:15:12] <jthornton> XXCoder: did you print any of the wire clips I made?
[06:15:33] <XXCoder> nah cant print while weekl
[06:15:49] <zhivko1> Actually I am not behind real machine... it is like a simulator mode reading actual position of axes and charting them in my 3d presentation...
[06:15:50] <XXCoder> last weekend was messed up plans because had to buy car and do bunch stuff
[06:16:07] <jthornton> did you find a car?
[06:16:07] <XXCoder> its in list though
[06:16:14] <XXCoder> yeah ford focus 2012
[06:16:30] <XXCoder> newer than I planned but for sure no issues till I get elio
[06:16:36] <jthornton> that should last till an eilo appears lol
[06:16:41] <XXCoder> indeed
[06:16:43] <zhivko1> jymm: I am reading position from linuxcnc computer
[06:16:44] <jthornton> or elio
[06:16:55] <XXCoder> a wild elio appears!
[06:17:40] <Jymmm> zhivko1: Well linuxcnc doesn't really support USB, it's best to ask them, which it seems you refuse to do.
[06:18:39] <zhivko1> ohh... I have running device here everything works except velocity on angles is too low... its not question of usb woorking yes or no - usb just works OK
[06:19:21] <zhivko1> jymmm: its like asking you about how g01 is working and you are repliying check if your computer is turned on...
[06:19:38] <Jymmm> zhivko1: Again, ASK THEM,. There is a reason why lcnc does not support usb, but they choosed to port it over, GO ASK THEM PLEASE.
[06:19:46] <jthornton> not really because g1 might be different now in machinekit
[06:21:33] <zhivko1> I would ask them if MK community would be so responsive like here :), but sadly it isnt.
[06:21:59] <_methods> lol
[06:22:08] <zhivko1> I am asking general motion planning question that is common also to LCNC. I believe that has not been changed
[06:22:34] <jthornton> we don't know if it is changed or behind or what
[06:22:34] <_methods> believe.......
[06:22:37] <_methods> keyword
[06:22:51] <zhivko1> I can do diff on src\emc\motion\motion.c
[06:23:08] <zhivko1> _methods: would that be ok than ?
[06:23:17] <_methods> we have no idea
[06:23:23] <_methods> we don't know what they've changed
[06:23:33] <_methods> we don't know what version the forked from
[06:24:14] <_methods> feel free to compare all the files you want
[06:24:16] <jthornton> why not just try your machine with LinuxCNC 2.7
[06:24:28] <_methods> i don't think you're going to find any volunteers to search for you in here
[06:26:43] <zhivko1> jthornton: does it work on BBB ?
[06:27:06] <jthornton> I don't know what a BBB is
[06:27:16] <_methods> good answer
[06:28:05] <jthornton> I also don't know what an it is...
[06:28:06] <zhivko1> beaglebone black
[06:28:14] <skunkworks> any moves involving rotory axis will fall back to 1 segment look ahead. Is that what you are seeing?
[06:28:14] <jthornton> what is that?
[06:28:39] <zhivko1> skunkworks: thank you it could be that - yes
[06:28:54] <zhivko1> skunkworks: how can I confirm this ?ž
[06:29:11] <jthornton> run with and without the rotary axis
[06:29:33] <zhivko1> https://beagleboard.org/black
[06:29:45] <jthornton> do a long rotary/linear move and a short one
[06:30:00] <zhivko1> I cannot run without rotary - I have CNC program that is written for rotary...
[06:30:17] <jthornton> write a test program
[06:31:19] <zhivko1> @skunkworks: OHHH I think I got better results when I had max_accel for rotary axes higher - so if it estimates speed with his first move - than this could be the case ?
[06:31:35] <zhivko1> with this first rotary move
[06:32:13] <zhivko1> skunkworks: in what piece of code is this angular look ahead dealt with ?
[06:32:13] <skunkworks> higher accel will always increase motion
[06:32:28] <skunkworks> zhivko1, I only use the software - I am not a programmer.
[06:33:25] <zhivko1> skunkworks: you maybe know why it is limited to 1 segment lookahead?
[06:33:44] <jthornton> change the rotary to a linear axis
[06:35:07] <zhivko1> jthornton: this seems funny - but I have my data in degrees now - would it help
[06:35:17] <zhivko1> ?
[06:35:27] <zhivko1> I find similar thread:
[06:35:28] <zhivko1> https://forum.linuxcnc.org/forum/20-g-code/29662-coordinated-motion-involving-rotary-axis
[06:38:39] <skunkworks> zhivko1, the developer that added N-lookahead has not gotten to rotory blending
[06:39:19] <zhivko1> sorry dont understand: "has not gotten to"
[06:39:27] <zhivko1> how do you mean this?
[06:39:37] <skunkworks> he hasn't finished it
[06:40:16] <skunkworks> so rotory motion falls back to the previous trajectory planner - 1 segment look-a-head
[06:40:41] <zhivko1> oh... do you maybe know is it in queue to finish or what's the situation with it ?
[06:40:47] <jthornton> skunkworks: do you know if MK is forked from 2.6?
[06:41:23] <skunkworks> I know it has the new TP - but I don't know if they have been keeping up with the fixes that rob has pushed.
[06:41:27] <zhivko1> in github is: This branch is 4162 commits ahead, 3797 commits behind LinuxCNC:master.
[06:42:03] <jthornton> I was just wondering
[06:45:16] <zhivko1> OK I can try what jthornton propose with changing rotary to linear axis ...
[06:45:22] <Deejay> moin
[06:46:15] <jthornton> morning
[06:46:45] <zhivko1> I think I would need to have in actual radius of pipe at which tooltip is moving...
[06:47:00] * jthornton tries to figure out how to serially charge the lipo batteries for the foamie
[06:47:48] <zhivko1> I mean I would need to acommodate for radius when I am writing program... jthornton - do you see any other option ?
[06:48:13] <jthornton> not for a rotary axis
[06:48:47] <zhivko1> skunkwork: you think ROB pushed some fixes that my case could benefit from ?
[06:49:34] <skunkworks> no - not that I know of involving rotory axis - there are some commits that added blending for UVW axis.
[06:50:59] <skunkworks> I don't know how machinekit pulls stuff from linuxcnc - if it does.
[06:51:01] <zhivko1> skunkwork: can I ask Rob? maybe he is in the know about lookahead code - in what coe looahead for planning is happening?
[06:51:20] <skunkworks> zhivko1, ask on the developer email list.
[06:58:48] <zhivko1> ok thank you guys
[06:59:01] <zhivko1> will try devel mailing list
[07:05:15] <zhivko1> another thing - will love to get this document:
http://jmkasunich.com/pics/emc2-motion-dataflow.pdf
[07:05:23] <zhivko1> anyobdy has it?
[07:11:55] <archivist> zhivko1, he lurks on the mailing list ask him
[07:12:18] <zhivko1> you mean jmkasunich?
[07:12:41] <zhivko1> devel mailing list or ordinary ?
[07:13:18] <archivist> I have seen him write a message in the last week or so
[07:14:16] <archivist> either/both lists
[07:24:43] <skunkworks> might be
http://linuxcnc.org/docs/devel/html/code/code-notes.html
[08:01:41] * jthornton just set a new record on the elliptical 3.375 miles in 30 minutes
[09:27:21] <cradek> guys, I know this is controversial, but I don't think it helps to pretend we can't help with things we can help with. you are right that there are many questions that are mk-specific, and it's frustrating when we get questions because mk doesn't have documentation, but general hal/gcode/motion questions really aren't like that. I think it benefits both communities if we work together when possible.
[09:28:36] <cradek> (it looks like skunkworks hit on the answer and it's the same answer we've given so many times: make your accels as high as possible, make your moves as long as possible, and it'll be better.)
[09:52:24] <nos> Jymmm: He didn't show up today. I think he destroyed a 500 euro facemill too. The machine wasn't locked out. He's a student, same as me. Adult. Sober. Not a native to the country.
[09:53:42] <nos> One of the bolts were tensioned properly, so it's not an issue of ignorance but one of laziness and lack of regard for others.
[09:54:42] <nos> But I have happier things to think about today!
[09:56:48] <nos> Today I started making some legit art on the lathe. However, surface finishing & protection vexes me. Should I ignore structural steel completely if I want surfaces to stay nice, flat and shiny?
[09:58:26] <archivist> very variable hardness, only a mild steel, not selected for machining, work hardens
[09:59:14] <archivist> a good finish is a combination of of problems
[10:01:26] <cradek> there are some steels that have lead added for easy machining and a smooth finish, like 12L14
[10:01:58] <archivist> "free cutting"
[10:02:01] <cradek> of course brass is good, but expensive
[10:02:48] <archivist> or polish/grind after machining
[10:04:03] <nos> I'm able to get a decent finish on this stuff. It's cold drawn rod. With a 0.4 mm radius D-type insert and just the right feedrate & depth of cut, the surface doesn't gall.
[10:06:55] <archivist> lubricant can help, change cutting speed as well
[10:08:39] <nos> Oh right, yeah I'll try some lube and a faster speed still. - I was thinking I'd get a strip of soft leather and 2 grits of polishing compound for getting the toolmarks out, but after that I'm at a loss.
[10:10:43] <archivist> only 2 grits!, use more
[10:11:27] <archivist> a mirror finish is possible on almost anything
[10:11:57] <nos> I'd prefer not to bring any toxic chemicals along. Even the brazing flux powder I brought caused trouble, with someone just opening the lid and taking a whiff off it instead of reading the label.
[10:11:57] <nos> ah
[10:12:16] <nos> Are there any polishing compounds which also cause maybe case hardening through hemistry?
[10:12:26] <nos> ~chemistry
[10:12:37] <archivist> not aware of any
[10:15:07] <archivist> I tend to use wet and dry going up the grades to 2000 for most stuff, 3M polishing film for better stuff
[10:16:31] <nos> Sweet, I'll look into that polishing film stuff. Smells like science!
[10:16:39] <archivist> and a burnisher for pivots where you want both the mirror finish and the work hardening for less wear in use
[10:18:32] <nos> Oh, a moulding tool?
[10:19:20] <archivist> no burnishing
[10:19:47] <archivist> micron paper
https://www.cousinsuk.com/category/micron-paper-3m
[10:21:08] <archivist> this shows the pivot file/burnisher
http://www.davewestclocks.co.uk/pivot.polishing%20for%20clocks.htm
[10:22:14] <archivist> not cheap
https://www.cousinsuk.com/product/pivot-file-burnisher-vallorbe-swiss
[10:23:04] <archivist> make you own with a bit of hss and rough it with wet & dry cross ways
[10:24:36] <archivist> all depends on size too
[10:25:09] <SpeedEvil> is it basically a very, very blunt file?
[10:26:04] <nos> We have lots of broken carbide endmills... because students.
[10:27:18] <archivist> never seen a mirror finish from a blunt file so not really
[10:27:39] <SpeedEvil> hmm.
[10:28:05] <nos> So I can't just take a file to a belt sander? It has to have polished flats and deep-ish grooves?
[10:28:12] <archivist> I found trying carbide as a burnisher not that easy
[10:28:44] <archivist> grooves almost non existent
[10:29:32] <archivist> very smooth and oiled, reasonable pressure, you are forming the surface not cutting
[10:30:05] <nos> I'ma give it a go come Monday. We have Friday off.
[10:32:02] <nos> Oh, right. That reminds me, I have taken a file to galled HSS drill bit necks a few times now. File wins every time. But the file is super-high carbon iron, isn't it?
[10:37:12] <archivist> cannot find a sensible video
[10:42:35] <nos> Thanks for your help though!
[10:44:25] <archivist> wet & dry and burnishing
http://www.collection.archivist.info/searchv13.php?searchstr=webb+clock
[10:46:06] <nos> Oh wow, you're actually making a clock!
[10:47:01] <nos> Makes me think one ought to ask Clickspring for a video on the shinyfier.
[10:47:55] <pink_vampire> archivist: maybe you have an idea
[10:48:16] <pink_vampire> why brass brake end mills?
[10:48:44] <pink_vampire> i'm working on the same settings that i'm cutting aluminum.
[10:49:31] <pink_vampire> 1000rpm, 0.5doc, 4f 1/8" carabide endmills
[10:49:57] <MacGalempsy> morning
[10:50:21] <pink_vampire> it work fine but without any notice it snap the end mill,
[10:50:28] <pink_vampire> hi MacGalempsy
[10:50:53] <MacGalempsy> pink_vampire: making any progress with your printer?
[10:51:04] <pink_vampire> not much
[10:51:31] <pink_vampire> i'm not happy with the rails
[10:51:42] <MacGalempsy> alignment?
[10:52:43] <pink_vampire> the printing just kill the dovetails sooo fast
[10:53:02] <pink_vampire> i'm running the machine on the max speed
[10:53:03] <archivist> nos, I was working as a clockmaker, that was made for customer
[10:53:09] <MacGalempsy> really you should use your mill for milling. make a dedicated printer
[10:53:19] <archivist> pink_vampire, speeds and feeds are not the same
[10:53:51] <pink_vampire> 5000mm/min..
[10:54:09] <pink_vampire> way too fast for dovetails
[10:54:28] <MacGalempsy> check out my panel layout. once the cable channel caps are done, I will finsih wiring the connectors
[10:54:30] <MacGalempsy> https://flic.kr/p/NFnRF1
[10:54:34] <archivist> also depends what sort of "brass"
[10:54:56] <pink_vampire> some 1/16" the i got free
[10:55:23] <archivist> naval brass will break anything, engraving brass is nice
[10:55:34] <pink_vampire> MacGalempsy: it look "right
[10:55:41] <pink_vampire> "right"
[10:55:52] <pink_vampire> I like the printed duct
[10:56:12] <pink_vampire> but it's look too yellow
[10:56:26] <MacGalempsy> thanks! I keep procrastinating the project, so have been no lifing in the last few days trying to get it over with
[10:56:52] <MacGalempsy> its gold filiment, I ran out of black
[10:57:09] <pink_vampire> I need to solve some over heating that I have on a transformer that I'm trying to make
[10:58:47] <MacGalempsy> There is the rest of it.
https://flic.kr/p/NRGfBP
[10:59:21] <pink_vampire> very nice
[11:00:34] <MacGalempsy> I am hoping to get it down to just the milling stuff, like the bed brackets and leadscrews
[11:01:27] <pink_vampire> i have a problem with large g-code files on mach3
[11:01:42] <pink_vampire> and linux cnc don't support my machine
[11:04:20] <archivist> linuxcnc does support your machine, when you set it up correctly
[11:04:40] <MacGalempsy> have you checked out thingiverse website for parts?
[11:05:29] <MacGalempsy> or checkout reprap.org
[11:05:49] <MacGalempsy> with your cnc, you should be able to make some good brackets
[11:08:17] <pink_vampire> archivist: i need 2 signals one is "in motion" and the other one is for the alarm at the finish
[11:08:18] <pink_vampire> also i need probe support
[11:08:18] <MacGalempsy> all that seems doable with lcnc
[11:08:18] <pink_vampire> and way to add few buttons in linux cnc
[11:09:32] <archivist> many ways to add buttons
[11:10:11] <MacGalempsy> the learning curve was steep for me, I am still trying to get a handle on many aspects. it is a lot of reading
[11:11:45] <gregcnc> if linuxcnc can send an email at program finish it can turn on a light

[11:13:15] <pink_vampire> i have 2 computers.
[11:13:48] <pink_vampire> P4 3ghz, and q9300
[11:14:15] <pink_vampire> i want to use the machine as 5 axis machine at the end
[11:14:33] <pink_vampire> the 3ghz can do it?
[11:15:06] <archivist> run latency test, pass=yes generally
[11:15:07] <cradek> boot the live image from usb and run the latency test on both. use the machine with lower latency.
[11:16:34] <pink_vampire> i need it for 3d machining
[11:16:43] <pink_vampire> 500,000 lines and up..
[11:17:11] <archivist> I finally got around to trying the usb stick method a week ago, Just works TM
[11:17:54] <archivist> write better gcode then you dont need so many lines :)
[11:19:27] <gregcnc> archivist.. you hand code 3d surfacing?
[11:19:32] <pink_vampire> for 3d machining?
[11:19:32] <Deejay> :D
[11:19:32] <Deejay> by hand! ;)
[11:19:32] <pink_vampire> yeah.. sure...
[11:19:49] <archivist> yes
[11:20:14] <gregcnc> that isn't a mathematical formula...
[11:20:37] <archivist> technically yes, but they are mathematical forms :)
[11:21:07] <Deejay> it is! ;)
[11:21:11] <Deejay> you can approximate every contour with lots of sinus and cosinus! ;)
[11:21:46] <gregcnc> or you can use CAM
[11:21:58] <Deejay> hm, thats the easier way ;)
[11:21:58] <gregcnc> and have a week free to do something
[11:22:03] <archivist> gcode scales easier :)
[11:22:18] <gregcnc> CAD does a good job scaling
[11:23:06] <archivist> edit one or three variables rerun, no cam stage
[11:23:53] <archivist> here is another person doing it
http://bodgesoc.blogspot.co.uk/2016/11/cams.html
[11:23:57] <Deejay> jo, i would prefer 'programmed gcode'
[11:24:02] <Deejay> parametric
[11:24:20] <Deejay> for simple things this works fine
[11:24:57] <archivist> I have a parametric gcode escape wheel routing in gcode, adjust depth and number of teeth
[11:25:13] <Deejay> yeah
[11:25:33] <gregcnc> this isn't 3d surfacing, but that's OK there is a place for everyhting
[11:27:21] <archivist> well it 3d surfaces a curve with a slitting saw
[11:28:28] <archivist> https://www.youtube.com/watch?v=adT8Dr5JZ4c
[11:28:49] <gregcnc> https://www.youtube.com/watch?v=8Lh600hVyt8
[11:28:56] <archivist> 2008 rather a long time ago
[11:31:13] <gregcnc> macro/sub prgoram type things are useful, but don't require 500,000 lines from CAM either
[11:33:12] <archivist> sort of stuff I do
http://www.archivist.info/cnc/generate_gear_n_teeth.ngc
[11:34:54] <gregcnc> I should get around to writing one to generate involute gears.
[11:35:13] <archivist> that one I just posted does
[11:35:32] <Deejay> archivist, needs latest version of linuxcnc? gives an error for me
[11:35:42] <archivist> I have a bevel one too
[11:35:54] <gregcnc> with what sort of cutter?
[11:36:03] <archivist> hell no that is for years ago
[11:36:13] <archivist> for/from
[11:36:18] <Deejay> bad character 'a' used, near line 9
[11:36:19] <Deejay> hm
[11:36:21] <archivist> 20 deg
[11:36:36] <archivist> you need an A axis configured
[11:36:51] <Deejay> ah!
[11:37:58] <archivist> I have something similar but it is fed with variables from
http://www.archivist.info/gear/designbevel.php
[11:39:28] <archivist> but there is a mistake somewhere
http://www.collection.archivist.info/searchv13.php?searchstr=bevel
[11:39:29] <Deejay> dont have :(
[11:39:29] <Deejay> doesnt matter, just wantet to look
[12:42:32] <FinboySlick> datron milling machines are way too clean to be milling machines ;)
[13:11:49] <Tom_L> clean is an operator preference
[13:14:13] <Jymmm> https://www.youtube.com/watch?v=3YzAl29Ag78
[13:21:34] <FinboySlick> Jymmm: That machine is so rigid that it is reality that bends around it.
[13:21:59] <Jymmm> Heh, that machines will NEVER look that clean ever again =)
[13:23:10] <FinboySlick> I think they filmed it with a smartphone or somesuch. The whole image bends at some point while the tool stays straight.
[13:26:48] <Jymmm> What are the limitations of a $89 arc welder? Could it do 1/4" steel plate?
[13:28:46] <IchGucksLive> hi
[13:30:02] <IchGucksLive> Deejay: up and running on 4Axis
[13:30:59] <IchGucksLive> Deejay: use a SIM mashine
[13:31:23] <Loetmichel_> FinboySlick: datron machines are even more impressive when you see them in "person"
[13:31:46] <Loetmichel_> but sadly: waaaaayyyyy out of "hobbyists" pricerange
[13:32:25] <IchGucksLive> some hobbyists like the US trillionäirs may get it
[13:33:02] <IchGucksLive> and if on Thuesday the russions take over the USA it will be more afortable
[13:33:31] <IchGucksLive> as the whitehouse is overtaken by russion based and well speeking americans
[13:35:15] <IchGucksLive> Q the support frame under a mashine has this a special name
[13:38:16] <CaptHindsight> Jymmm: only if you make a few passes, is it a 100A (20% duty cycle) $89 stick welder?
[13:40:00] <CaptHindsight> Jymmm: much absurdity in the Chinese welder specs
[13:41:04] <IchGucksLive> Jymmm: amazon also hase German stamos lowcost welders
[13:42:48] <IchGucksLive> CaptHindsight: you are the man for supply how about cheep hwin
[13:43:05] <IchGucksLive> on Int stock
[13:45:21] <IchGucksLive> Loetmichel_: warst du bei denen im showroom shon mal in deiner nähe wiesbaden
[13:47:30] <gregcnc> finboyslick those datron use ethanol for coolant. it all dries up. that post has to be crazy it turns coolant on only when it's in the cut
[13:48:17] <IchGucksLive> gregcnc: pup may be of time
[13:48:26] <IchGucksLive> coolant pump
[13:48:32] <IchGucksLive> timedelay
[13:48:55] <Loetmichel_> IchGucksLive: no
[13:48:58] <IchGucksLive> cause on low coolant media level
[13:49:05] <gregcnc> every time it lifts away, coolant turns off
[13:49:41] <gregcnc> not only for tool change, any clearance or retract move
[13:50:07] <IchGucksLive> hommade improov
[13:50:20] <IchGucksLive> pen up m3
[13:50:25] <IchGucksLive> pen down m8
[13:50:32] <IchGucksLive> m13
[13:50:55] <gregcnc> what
[13:51:01] <IchGucksLive> the post
[13:51:34] <gregcnc> it's not writing anything
[13:52:13] <IchGucksLive> if you change from M13 to m3 it makes coolant off and spindle stil on and the other wa eqal
[13:53:48] <IchGucksLive> @all there is a new version off sheetcam for testing no linelimits on linux 32 and 64 bit
[13:54:41] <Loetmichel_> hopefully they have a good air exhaust system ;)
[13:55:02] <Loetmichel_> <- uses up to two spray cans of IPA a day on the Mill...
[13:55:17] <Loetmichel_> ... on some evenings the air in the workshop is nearly flammable ;)
[13:55:52] <IchGucksLive> milling macrolon ?
[13:56:02] <IchGucksLive> or alu
[13:56:38] <Loetmichel_> alu

[14:04:47] <Jymmm> CaptHindsight: Yeah, 20% duty cycle

[14:06:57] <FinboySlick> Jymmm: You'll burn your house down.
[14:07:15] <IchGucksLive> wood welder stick
[14:07:51] <Jymmm> FinboySlick: only 20% of it
[14:08:20] <IchGucksLive> welding it to a truck and move across the US
[14:13:55] <CaptHindsight> Jymmm:
http://www.homedepot.com/p/Lincoln-Electric-Weld-Pack-HD-Feed-Welder-K2188-1/100031840 up to 1/8" mild steel
[14:14:39] <CaptHindsight> they are made for quick and dirty sheet metal welds
[14:16:02] <FinboySlick> I guess if you manage to do good welds with one of those, you become a champion with real welders ;)
[14:16:59] <CaptHindsight> Jymmm: even worse "2: This is an A/C welder (they saved the cost of the diode > $1), which turns welding into a complete splatter-fest, requiring excessive clean-up (doesn't really matter due to point 1 - it's useless)"
[14:17:27] <CaptHindsight> Pros:
[14:17:28] <CaptHindsight> If you are a bachelor you can use it as an expensive door-stop.
[14:19:06] <CaptHindsight> FinboySlick: I had a basic Lincoln years ago. Was ok for a very limited range of sheet metal with the flux wire
[14:20:52] <Jymmm> CaptHindsight and the lincoln one is DC ?
[14:22:28] <CaptHindsight> Jymmm: yeah, but I'd look for a used higher end model unless you have a really tight budget
[14:23:23] <sync> mig/mag transformer machines usually are relatively cheap
[14:23:23] <CaptHindsight> "Flux core plus AC output equals spattering. I did a DC electrode negative mod and hobart .030" wire and tip. After the $35 mod it is a new machine and puts down a beautiful bead with slag. I used a 100A 1000V rectifier and a 120,000uF cap to do the DC mod. The next upgrade will be a good cooling fan for to increase the duty cycle. With a little work it's a pretty decent $150 welder."
[14:25:09] <Jymmm> I think I have a 400A bridge around here ;)
[14:25:53] <IchGucksLive> im off Gn8
[14:25:53] <FinboySlick> Jymmm: Well, find a cap and a transformer and skip the welder itself ;)
[14:26:00] <sync> caps are no good, inductors are good
[14:26:56] <Demure_> I bought some coiled wire in hopes it would serve me well for wiring up some home switches, but after stripping them I realize they were intended for headphones and are rather thin, would this be an issue?
[14:27:48] <CaptHindsight> Demure_: the current is pretty low for home switches
[14:28:07] <Demure_> That's what I figured, but I was wondering if there's such a thing as 'too thin', even for a home switch.
[14:28:22] <Jymmm> Demure_: It could very well break with excess movement as I've never seen that type of wire be "durable", it's moe of a metalic film sometimes.
[14:28:49] <CaptHindsight> yeah, flexibility and durability
[14:29:38] <Demure_> It's copper wire and the outside is quite durable
[14:29:50] <Jymmm> Demure_: you might look into 'energy chain' instead
[14:30:50] <Demure_> You mean cable carriers? I have 'em here, but for the short distance it seemed a bit overkill.
[14:31:29] <Jymmm> CaptHindsight: Since I've never welded, yeah, kinda on a tight budget. But the DC mod sounds reasonable. I have tons of fans I could install too
[14:32:50] <Jymmm> CaptHindsight: That stove I was looking at... they wont ship to calif and it's not available anywhere else (ebay is drop ship from them as well), so looking at alternatives.
[14:33:19] <Jymmm> CaptHindsight: I found a local source for 3" straight muffler pipr and they can cut/bend it rather cheap.
[14:33:58] <Jymmm> I want that damn stove! lol
[14:34:33] <CaptHindsight> how much does it weigh?
[14:34:41] <Jymmm> 47lbs
[14:35:24] <sync> Jymmm: look into a used mig/mag, they are hard to break and much better than that thing
[14:35:33] <CaptHindsight> Jymmm: have a messenger service pick it up from the Nevada warehouse
[14:35:50] <CaptHindsight> drop it at UPS for the rest of the way to you
[14:36:27] <Jymmm> CaptHindsight: I'll have to see what is the CHEAPEST way to ship/freight it
[14:36:50] <Jymmm> sync: I'll look around craigslist
[14:37:59] <CaptHindsight> heh, I wonder if you can have it in will call and have UPS get it
[14:40:16] <Jymmm> CaptHindsight: blind ship to a UPS store; then have the UPS store ship to me =)
[14:45:45] <CaptHindsight> I had to have something shipped earlier this week where they didn't offer shipping or have a printer to print a label
[14:46:31] <Jymmm> lovely
[14:47:47] <sync> wat
[14:49:12] <Jymmm> It be almost as cheao to rent a car drive to NV andd back, other than the cost of gas
[14:52:59] <gregcnc> capthindsight, did they have electricity?
[14:58:17] <Jymmm> or indoor plumbing?
[14:59:01] <FinboySlick> Heck, even the Amish take credit cards.
[14:59:49] <CaptHindsight> gregcnc: electricity and maybe a shed
[15:00:10] <gregcnc> depends which amish
[15:00:36] <CaptHindsight> it's also possible they are also still in the 60's or 70's
[15:00:51] <CaptHindsight> also
[15:01:14] <gregcnc> lol
[15:01:36] <gregcnc> so did you send a carrier pigeon?
[15:02:44] <CaptHindsight> messenger named after a desert animal
[15:03:53] <CaptHindsight> ends up that the Fedex/kinkos only charged me $35 for the box vs the threatened $90
[15:25:24] <Jymmm> rpad runner freight
[15:25:29] <Jymmm> road runner freight
[15:27:35] <CaptHindsight> will they take a box not on a palate or crated?
[15:27:59] <CaptHindsight> palate/pallet
[15:28:20] <CaptHindsight> keep it off your tongue :)
[15:30:48] <gregcnc> was that lathe still there this morning?
[15:32:22] <CaptHindsight> i didn't check, too busy

[16:22:04] <Tom_L> cross the border to get your illegal stuff
[16:22:20] <Jymmm> Tom_L: wrong time of year
[16:24:22] <Jymmm> Tom_L: I've already had someone smuggle in a quart of MEK from Nevada for me
[16:25:19] <Jymmm> Maybe I should stock up on stump remover befor eit becomes illegal too
[16:25:32] <Jymmm> oh, and white vinegar too
[16:25:58] <XXCoder> why would that be illegal? vingear?
[16:26:10] <Jymmm> XXCoder: every fucking thing else is
[16:26:24] <Jymmm> XXCoder: It's an acid
[16:27:20] <Tom_L> move to Jew Jersey
[16:27:22] <Tom_L> New
[16:27:45] <Jymmm> Too many Jooooos =)
[16:28:23] <Jymmm> That's funny... I can imagine a jewsish guy with a nj accent... oh vey
[16:29:02] <Jymmm> Kosher Jersey Shore?
[16:29:53] <Tom_L> is Ca smog free due to all their laws?
[16:31:17] <Jymmm> If you move up the mountain, you dont have to smog your vehicles
[16:32:09] <Tom_L> you'll be down with the rest of em after one good mud slide
[16:32:59] <Jymmm> I mena from 3000ft to 8000ft. If that was a mud slide, even YOU would be effected.
[17:24:58] <Deejay> gn8
[17:41:51] <jesseg> What's a good linear encoder scale that puts out quadrature ?
[18:17:42] <MacGalempsy_> had a worry there for a bit.the board would not connect, but a reversed connection solved the problem
[19:30:10] <CaptHindsight> jesseg: where are you located? Glass scales? 5 or 1um?
[19:31:42] <CaptHindsight> http://www.dropros.com/DRO_PROS_Digital_Readout_Scale.htm
[19:34:29] <malcom2073_> You can often get cheap glass scales used from old DRO's
[19:36:06] <pfred1> malcom2073_ on every streetcorner, I'm sure!
[19:36:24] <malcom2073_> pfred1: Depending on what part of the world you're in... yeah :)
[19:36:36] <zeeshan> who needs glass scales
[19:36:51] <malcom2073_> People who need linear encoders?
[19:36:55] <CaptHindsight> needs or wants?
[19:36:59] <zeeshan> i have a few spare ones
[19:37:01] <roycroft> if you're livin' with glass scales
[19:37:04] <zeeshan> but theyre only 0.001" precision
[19:37:06] <roycroft> then don't throw chips
[19:37:08] <zeeshan> er resolution
[19:37:18] <zeeshan> i was planning to use them on the plasma cutter
[19:37:20] <zeeshan> but kind of pointless
[19:37:25] <zeeshan> worst application to use em
[19:37:25] <zeeshan> lol
[19:37:32] <malcom2073_> The difference between a need and a want is a matter of discresionary income
[19:37:37] <zeeshan> need to get rid of em
[19:37:47] <CaptHindsight> I want what I need
[19:37:49] <malcom2073_> Lol yeah
[19:38:01] <malcom2073_> zeeshan: plasma, so very long?
[19:38:14] <zeeshan> they be 36" long
[19:38:17] <zeeshan> i want to build a 36x36
[19:38:21] <zeeshan> but its too dirty
[19:38:29] <CaptHindsight> I don't always need what I want
[19:38:30] <malcom2073_> yeah plasma is dirty dirty
[19:38:43] <malcom2073_> You can't always get what you want
[19:39:00] <malcom2073_> but if you try sometimes you might find you get what you need
[19:39:51] <CaptHindsight> what if you try for what you want but don't need, is that also true that sometimes you might find it?
[19:40:22] <CaptHindsight> welcome to Rolling Stones Philosophy 102
[19:40:27] <pfred1> I spent two days designing, and modeling my control box, and it doesn't work
[19:40:49] <malcom2073_> CaptHindsight: I'm fairly certain I didn't imbibe the prerequisite for this class
[19:40:57] <pfred1> but I guess that beats making it, and finding out
[19:41:19] <CaptHindsight> malcom2073_: B.S. 100-200 level courses? :)
[19:41:35] <malcom2073_> CaptHindsight: Alcohol, Cocaine, and Whores 101
[19:42:00] <malcom2073_> Oh hah!
[19:42:03] <malcom2073_> I just got that
[19:42:03] <pfred1> throw in some dope, and I'm in
[19:43:18] <malcom2073_> Dope man!
[19:44:12] <pfred1> not the kiddie kind mond you
[19:44:18] <pfred1> mind you even
[20:07:26] <jesseg> CaptHindsight, sorry I stepped away a bit. I'm in Western Washington, and I don't know enough whether to want glass or lum, and I don't know what "lum" means in this case. Does Lum mean a thin aluminum cover over a magnetic pattern?
[20:08:15] <jesseg> malcom2073_, cool idea -- do you know if the glass scales from old DRO's have a quadrature output suitable for CNC closed loop operation?
[20:08:51] <malcom2073_> Suitable is a funny word, but yes... you could in theory do closed loop like that. It's IMO a bad idea. You should firm up your motion control enough that you can do encoders on the motors
[20:09:29] <BeachBumPete> hey folks howsitgoin?
[20:10:29] <jesseg> malcom2073_, agreed, however, with preloaded ball nut feed screws, do you think it would be acceptable for hobby use? The goal of course is to eliminate feed screw / drive belt inaccuracies from positioning.
[20:10:39] <malcom2073_> Oh yeah, totally
[20:11:50] <jesseg> malcom2073_, okay cool. I didn't know if a DRO scale output some proprietary serial communications specific to the display unit or if they just put out standard quadrature
[20:12:33] <malcom2073_> Depends on the scale I'm sure
[20:13:34] <kasious> 4 sure
[20:16:02] <jesseg> malcom2073_, okay that make sense. So I'm hoping to find someone who's parted one out and knows how they go inside :D
[20:16:24] <malcom2073_> I have some old ones that output quadrature... but again, it depends a lot on the scale
[20:16:41] <_methods> western washington lol
[20:18:14] <jesseg> _methods, you know, yeah, up at the edge of the known world.
[20:18:25] <jesseg> just past the edge of civilization.
[20:18:34] <_methods> isn't the whole state western
[20:19:17] <jesseg> _methods, well, that doesn't mean that it doesn't have a western side and an eastern side, just like every city and town has the east end of town and the west end of town.
[20:19:30] <_methods> hehe
[20:19:52] <_methods> i don't blame you nobody wants to be associated with eastern washington
[20:20:04] <jesseg> _methods, I suppose made in the southern united states they might not understand principles like that, relying instead on the more simple principle that they are the universe :D
[20:20:09] <_methods> or even worse is eastern oregon
[20:20:26] <BeachBumPete> except for florida ;)
[20:20:38] <_methods> 'murrica's penis
[20:20:54] <BeachBumPete> no thats texas
[20:21:03] <_methods> lol
[20:22:44] <malcom2073_> I thought texas was the dingleberry
[20:22:55] <BeachBumPete> that too :)
[20:22:59] <jesseg> malcom2073_, what sort of old ones do you have, do you know?
[20:23:26] <jesseg> uhh, slide encoders that is.
[20:23:27] <malcom2073_> jesseg: No clue, the brand name is long since worn (or greased) off, they're really old. I plan on using them as a DRO on my lathe, hooked to an arrduino or some such
[20:23:48] <jesseg> I'm not tracking the rest of the of the conversation about various countryparts.
[20:24:04] <malcom2073_> Lotta noise in this channel sometimes, gotta tune it out :)
[20:24:07] <jesseg> malcom2073_, sounds like a neat plan
[20:24:17] <BeachBumPete> I'm noisy
[20:24:45] <_methods> tldr; pete is a dingleberry
[20:24:51] <malcom2073_> Hehe +1
[20:25:29] <BeachBumPete> if I'm one of those just imagine what _methods is :0
[20:25:36] <_methods> hehehe
[20:25:45] <_methods> nice recovery
[20:25:52] <jesseg> haha regarding DROPROS.com - I see the glass scales have 1 or 3 year warranty. The magnetic ones have 6 year warranty LOL.. K..
[20:26:05] <BeachBumPete> my damn checking account got hacked today
[20:26:29] <malcom2073_> BeachBumPete: Stop making your password "password"
[20:26:29] <BeachBumPete> someone is enjoying 250 bucks worth of port from a local liquor store on my dime
[20:26:32] <_methods> wasn't wells fargo was it?
[20:26:37] <BeachBumPete> no
[20:26:45] <_methods> whew
[20:27:01] <BeachBumPete> I had to cancel my card and now I have to go to the bank tomorrow and fill out a form
[20:27:18] <BeachBumPete> I also gotta call the cops apparently and fill out a form thru them
[20:27:20] <jesseg> BeachBumPete, wow sorry man that stinks
[20:27:29] <BeachBumPete> yeah indeed it do
[20:27:40] <_methods> yeah i got my card hacked a few months ago
[20:27:40] <BeachBumPete> then as if that was not fun
[20:27:53] <_methods> they caught the guy in a seatac airport with 100's of cards
[20:27:53] <BeachBumPete> a guy who works for the company I work for currently
[20:28:08] <BeachBumPete> got fired yesterday
[20:28:32] <BeachBumPete> and today apparently while I was at another location came into the building and threatened basically everyone there
[20:28:35] <tiwake> ponies
[20:28:48] <BeachBumPete> cops came
[20:28:58] <BeachBumPete> of course after he already left
[20:29:06] <_methods> nothing like some work place violence to liven up the week
[20:29:10] <jesseg> a day late and a doughnut short
[20:29:15] <BeachBumPete> oh yeah its great
[20:29:31] <BeachBumPete> he threatened the guy who fired him and his family apparently
[20:29:42] <BeachBumPete> said he was gonna shut down the company somehow
[20:29:47] <BeachBumPete> not good
[20:30:12] <BeachBumPete> how's that for channel noise? :)
[20:30:25] <malcom2073_> Florida
[20:30:27] <tiwake> BeachBumPete: probably file something with osha
[20:30:31] <tiwake> ohsa?
[20:30:32] <malcom2073_> It got its reputation for a reason
[20:30:33] <tiwake> whatever
[20:30:34] <_methods> concealed carry
[20:30:50] <BeachBumPete> heh same thing happened to me in Tennesse
[20:31:15] <BeachBumPete> what reputation?
[20:31:42] <BeachBumPete> _methods I do need to get my CC
[20:31:48] <jesseg> Nothing happened to me in Tennessee. Of course I haven't been there yet.
[20:31:58] <_methods> "need" is a strong word
[20:32:10] <BeachBumPete> I had several incidents like this in Tennessee over the 15 years I lived there
[20:32:20] <_methods> yep you need one then lol
[20:32:33] <jesseg> _methods, yeah "need" is only for things like food, shelter, clothing, and milling machines and lathes.
[20:32:33] <BeachBumPete> luckily none were directed at me
[20:32:42] <malcom2073_> BeachBumPete: Maybe you're the common denominator here?
[20:32:43] <malcom2073_> :P
[20:32:47] <_methods> hahahah
[20:33:10] <BeachBumPete> I almost got in a fist fight over something with one guy in a shop when I first worked in TN tho....that WAS directed at me LOL
[20:33:11] <malcom2073_> on a happier note: Tomorrow is my last day at my old job
[20:33:19] <_methods> on that note i'm carrying my ass to bed
[20:33:33] <BeachBumPete> how do you carry your own ass?
[20:33:47] <_methods> very carefully
[20:33:52] <malcom2073_> Same way you hoist yourself by your own petard
[20:33:54] <jesseg> malcom2073_, congratulations. Is the day after that your first day on your new job?
[20:34:02] <BeachBumPete> hehe
[20:34:07] <malcom2073_> jesseg: Day after the weekend, yeah :)
[20:34:09] <BeachBumPete> Gn8 chump
[20:34:24] <_methods> l8r bi0tch
[20:34:28] <BeachBumPete> hehe
[20:36:14] <jesseg> malcom2073_, wonderful
[21:39:22] <jdh> when I g10 l2 P1 R90 to make a part fit, I always have an incredibly hard time touching off. Anyone have any hints to remember what is where?
[21:42:05] <MacGalempsy> hello
[21:47:45] <BeachBumPete> Hey Mac
[21:55:23] <MacGalempsy> hey pete whats goin on?
[21:57:51] <BeachBumPete> meh not much you?
[21:58:00] <cradek> jdh: when I had several fixtures on my machine with different origins and rotations, I drew the origin and X positive direction on them with a sharpie
[21:59:09] <MacGalempsy> spent the day finishing up this electrical panel
https://flic.kr/p/NpZ2fL
[22:00:06] <MacGalempsy> should be able to mount it in the back door and wire it up to the motors tomorrow.
[22:00:06] <BeachBumPete> cool
[22:00:10] <jdh> cradek: arrow keys move machine x/y, but touch off is in the current orientation?
[22:00:28] <jdh> I end up trial and erroring until it shows the right spot
[22:00:58] <MacGalempsy> hoping to have in printing within the week
[22:01:35] <BeachBumPete> awesome
[22:02:55] <jdh> I had a vendor in today with samples of lots of printed parts. SS, Ti, AL, SLA, SLS? and misc. cnc'ed materials
[22:03:12] <cradek> jdh: (assuming you're using AXIS) touch off is in the coordinate system so if you're R90 and you jog against the left side of your fixture as you see it on the machine, you'd probably want to touch off Y because you're coming in from the +Y direction
[22:03:52] <jdh> using axis (never tried anything else)
[22:05:52] <cradek> did you follow my answer?
[22:06:49] <cradek> heh experimenting until it shows the right number works too...
[22:06:50] <jdh> yeah. I think I kind of figure that out each time, but it is usually months between needing to rotate
[22:06:56] <cradek> yeah
[22:07:07] <cradek> I also use it rarely
[22:07:13] <cradek> I use polar coordinates more than rotation
[22:07:31] <jdh> why polar?
[22:07:42] <cradek> for circular things!
[22:08:12] <jdh> never tried polar, but I just CAM most things now
[22:08:24] <pfred1> cradek hey how you doing?
[22:08:27] <cradek> hey
[22:24:05] <CaptHindsight> jesseg: 1 micron = 1um = the whole number greater than zero but less than two microns
[22:25:08] <CaptHindsight> 1um not lum
[22:29:45] <tiwake> CaptHindsight: half of all "modern" fonts are retarded for this reason
[22:29:54] <tiwake> maybe more than half
[22:30:23] <CaptHindsight> 1 never noticed :)
[22:30:33] <tiwake> ...ouch
[22:30:51] <tiwake> that was a really _real1y_ bad joke
[22:31:02] <CaptHindsight> 1Il
[22:31:18] <CaptHindsight> wonder what it renders like on his end
[22:32:25] <tiwake> CaptHindsight:

[22:33:35] <tiwake> also,

[22:35:00] <cradek> http://timeguy.com/cradek-files/emc/irssi.png
[22:35:35] <tiwake> yeah, thats a good font
[22:35:44] <tiwake> also, O0
[22:35:46] <cradek> I think I first encountered this font on a Sun in '92 and I've used it probably every day ever since
[22:36:20] <tiwake> I hate VIN numbers when you cant tell the difference between O and 0
[22:36:27] <tiwake> ...which is all of them
[22:36:59] <tiwake> its just office people passing laws to make everyone suffer
[22:37:06] <pfred1> this is the font i use for IRC urxvt -rv -fn -gnu-unifont-medium-r-normal--16-160-75-75-c-80-iso10646-1
[22:37:56] <cradek> guess I don't have that one
[22:38:15] <pfred1> you can get it through aptitude
[22:38:40] <pfred1> that's where I got it from
[22:39:25] <pfred1> aptitude install unifont
[22:39:56] <pfred1> though it might be xfonts-unifont - PCF (bitmap) version of the GNU Unifont ?
[22:40:52] <pfred1> yeah it probably is the latter Package: xfonts-unifont State: installed
[22:41:25] <pfred1> then you can see like every whacky character
