02:24 AM XXCoder: cool
02:43 AM Deejay: moin
02:53 AM stewit: auch moin
02:55 AM Deejay: :)
02:57 AM RyanS: I'm thinking of using polymer bushings (Igus) ffor my plasmas Z axis
02:58 AM RyanS: apparently they good on contaminated environments
03:21 AM gloops: any progress lcvette
03:21 AM lcvette: i beat it!!!! gomoccapy lives, atc function works! everything works.. mostly
03:21 AM lcvette: few quirks to work out but none i can't figure\
03:22 AM lcvette: windows did it
03:22 AM lcvette: it was windows fault
03:23 AM gloops: windows?
03:23 AM lcvette: somehow the ngc macros files got blocked when going through windows
03:24 AM lcvette: some made it through and some made it through but with a variation made to them on the file extension
03:24 AM gloops: ahh youre running wheezy in a virtual box?
03:24 AM lcvette: ie..toolchange.ngc~
03:24 AM lcvette: no im back on stretch
03:24 AM gloops: lol
03:24 AM RyanS: gmocappy is what I want to use on my plasma but I would be lucky if I could work out how to get axis working
03:24 AM lcvette: with updated linuxcnc 2.7.13
03:25 AM lcvette: im running gmoccapy
03:25 AM lcvette: seems to work fine in 2.7.13
03:25 AM lcvette: but was having issues in 2.7.11 in stretch
03:25 AM lcvette: if you use stretch, be sure to to sudo apt-get upgrade
03:26 AM gloops: i wont be using stretch i dont think
03:26 AM lcvette: update won't do it
03:26 AM gloops: route 1 for me, keep it simple
03:26 AM lcvette: its awesome now that i know how to get what i needed
03:26 AM gloops: parport, breakout board, linuxcnc
03:27 AM RyanS: I have a dedicated fanless pc
03:27 AM lcvette: once i discovered the files got blocked from coming through somehow i went through and fixed them and had a couple minor debugs to fix after that and bam she opened right up
03:28 AM lcvette: almost fell out of my chair
03:28 AM lcvette: lol
03:28 AM RyanS: problem with gmocappy is I only know one person who has written a post for sheetcam--i wouldn't have a clue about how to do that
03:29 AM lcvette: ]post isn't going to change from gmoccapy to any other linuxcnc
03:30 AM lcvette: pretty sure they will all use the generic fanuc base gcode
03:31 AM lcvette: pretty standard
03:31 AM lcvette: gmoccapy is just the interface
03:32 AM lcvette: screenset
03:32 AM RyanS: is a plate marker hard to integrate? you need one output to trigger a pneumatic cylinder to drop the engraver down and another to trigger the engraver itself.. so I guess it's just 2 axis XY
03:34 AM lcvette: that you may need a special poist for
03:35 AM lcvette: post
03:35 AM lcvette: but the integration should be pretty easy
03:35 AM lcvette: just need the code to call for the outputs somehow
03:35 AM lcvette: probably with m codes
03:36 AM lcvette: that would be done in the post
03:36 AM lcvette: and would need built in delays for actuation before axis movement occurs
03:36 AM XXCoder: its captioned. nice
03:37 AM XXCoder: https://www.youtube.com/watch?v=wwMDvPCGeE0
03:38 AM lcvette: night guys, im wiped, its 4am and i have work in 4 hours
03:38 AM lcvette: gonna hurt tomorrow
03:39 AM RyanS: mechanically it's simple, but I'm ssurprised that the Z isn't needed, although I guess the cylinder forces the engraver onto the plate and acts like suspension on eneven plates
04:05 AM XXCoder: pretty cool but im sure that it already exists? https://www.kickstarter.com/projects/70718963/monkey-grip-gel-grip-tape-the-best-tape-youll-ever
04:16 AM XXCoder: dang! this would be super useful for me but so expensive https://www.kickstarter.com/projects/2132003782/pomera-pocket-typewriter-with-e-ink?
05:03 AM Loetmichel: morning from the bathtub... MAAN this notebook here hasnt booted in a long time... Update, reboot, update, reboot... when its done the water will be cold :-)
05:04 AM gloops: someone near me is making a 10x5ft dragknife table
05:07 AM gloops: not sure how sticky vinyl is cut in the trade, whether a dragknife would be good enough, useful thing though
05:08 AM RyanS: what's the deal with measurement in the UK? they seem to use metric for most things except miles /roads, speed? arn't you officially metric?
05:08 AM SpeedEvil: heated knives can be wonderful
05:09 AM miss0r: SpeedEvil: Especially for cold butter
05:09 AM SpeedEvil: RyanS: pretty much, but politicians thought people were too stupid and would drive 60% too fast if they put up new signs
05:09 AM miss0r: lol
05:09 AM gloops: Ryan mainly metric, the EU has forced a lot of things that had lingered on in imperial to turn metric
05:09 AM gloops: like food weights and measures
05:10 AM RyanS: a Brexiteer?
05:10 AM gloops: i am yes
05:12 AM gloops: thing is, everybody knows what a pound of apples looks like, or a pound of steak, nobody knows what a kilo looks like
05:12 AM SpeedEvil: No I don't.
05:13 AM RyanS: that made me think of Great British Railway journey's, I really like that show and Michael Portillo is a good host. then I read he's a conservative politician, Thatcherite type.. eww
05:14 AM gloops: hes pro EU though i think
05:14 AM RyanS: I still watch the show though
05:14 AM RyanS: yes
05:15 AM gloops: it wont be an issue for much longer i dont think, Italy could well be the nation to bring it down now
05:15 AM RyanS: apparently 'doing a Portillo' is a common British meme?
05:15 AM gloops: not in my circle lol
05:16 AM RyanS: I don't really get it, something like loosing in a massive landslide
05:17 AM gloops: i cant remember now, he had a very promising future career, think there was some scandal involved
05:18 AM RyanS: maybe he just loved trains too much lol
05:22 AM SpeedEvil: I thought conservative politicians only died due to autoerotic asphixiation.
05:23 AM gloops: well time for a bit of work
05:23 AM fragalot: Hey
05:46 AM jthornton: morning
05:56 AM RyanS: hi
05:58 AM RyanS: was that your plasma table that uses belt axes?
05:58 AM jthornton: yes my plasma has belt drives on X and Y
05:59 AM jthornton: http://gnipsel.com/shop/plasma/plasma.xhtml
06:09 AM RyanS: i'm leaning towards that.. easier to align than rack and pinion, anti backlash and plasma has no cutting loads to worry about forces
06:12 AM jthornton: if I was to do it again I'd go with the next bigger size belt on the Y axis
06:13 AM RyanS: what size do you think? metric here but there's equivalents
06:14 AM jthornton: I think my X is 1/2" wide
06:15 AM jthornton: curved tooth is better
06:16 AM RyanS: that's decent, and I guess with belts good quality doesn't cost a ton
06:16 AM Tom_itx: lcvette, good to see you got it working
06:17 AM Tom_itx: so the ~ at the end of those files was it ehh?
06:17 AM RyanS: it's a shame GT3 isn't readily available in Australia
06:18 AM jthornton: I think I used XL belt because it is available in cut to length
06:18 AM jthornton: morning Tom_itx
06:20 AM RyanS: because although HTD is rounded tooth it's for high load, low noise
06:21 AM RyanS: AT is what you want for motion control application I was told
06:21 AM fragalot: you could also go the route that roland went through on my engraver
06:21 AM fragalot: steel cable wrapped around pulleys :P
06:21 AM RyanS: ewww really
06:22 AM fragalot: yeah
06:22 AM RyanS: where's the traction?
06:22 AM RyanS: grip
06:22 AM fragalot: steel cable on alu pulley
06:23 AM fragalot: I can't make it slip by hand, and this machine is a good 15yrs old I think and doesn't really show any signs of wear on them
06:23 AM RyanS: interesting
06:31 AM Tom_itx: morning jthornton
06:35 AM Tom_itx: looks like you're gettin wet today
06:37 AM jthornton: yea just let the chickens out and it's a bit wet outside
06:47 AM miss0r: There we go. Now the shop is 'almost' clean... still inching forward :D
06:47 AM miss0r: Better take a break :D
06:49 AM RyanS: are they egg chickens, food chickens or both?
06:53 AM fragalot: miss0r: :D
06:54 AM miss0r: fragalot: Have you completed the rest of yer' ballscrews yet? :D
06:54 AM RyanS: deep fried chicken (in a Colonel Sanders voice)
06:58 AM fragalot: miss0r: no, replaced the lighting in the cellar & am currently browsing around for epoxy floor coatings vs a standard floor paint..
06:59 AM miss0r: fragalot: Keep in mind you basement floor needs to be able to 'breathe'
07:00 AM fragalot: hence the browsing around
07:02 AM miss0r: well, epoxy is the oposite ;)
07:02 AM miss0r: I wanted that for my basement floor, but was told I was an idiot by a guy who does this sorta stuff for a living. He told me to get the real basement floor paint stuff
07:03 AM fragalot: :D
07:06 AM fragalot: can't seem to find any basement floor specific paints
07:08 AM * fragalot looks for standard water based paints
07:16 AM miss0r: fragalot: So you had me convinced last night; I ordered a linear rail for the EDM
07:16 AM fragalot: :-)
07:17 AM fragalot: do you have a design in mind then?
07:17 AM miss0r: Yeah.
07:17 AM miss0r: I've decided to minimize it completely
07:17 AM miss0r: I will only have around 80-90mm travel on the Z.
07:18 AM XXCoder: "does AlMgSi1 make sense for milling parts?"
07:18 AM XXCoder: someone asked this on other channel
07:18 AM XXCoder: anyone know? lol
07:19 AM miss0r: XXCoder: file:///C:/Users/CNC/Downloads/material-data-sheet-en-aw-6082-almgsi1.pdf
07:19 AM miss0r: so, yes
07:19 AM miss0r: lol...
07:19 AM miss0r: I'll give you a link that makes sense :D
07:19 AM XXCoder: local file lol
07:19 AM miss0r: http://frebel-obstfeld.de/download/36
07:19 AM miss0r: there we go
07:20 AM XXCoder: thanks
07:21 AM RyanS: what about polymer bushings for a plasma Z? Igus claim to work well in contaminated environments and low loads
07:21 AM fragalot: xD
07:21 AM fragalot: RyanS: they work great - we use them a lot at work
07:22 AM miss0r: fragalot: I'm thinking about using some of that cast iron plate I have laying around to make a machine base for the EDM, for when I am going to use it in house, to have a nice steady mount for it
07:22 AM miss0r: I'm going to attempt making some acurate holes with it, for the safe pins... I realy want to have carbide pins :D
07:22 AM RyanS: fragalot: are they better suited to short distance?
07:23 AM fragalot: are you sure you want to do that? I know how much work it is to get a cast iron plate of that size to be truly flat
07:23 AM RyanS: so a Z axis
07:23 AM fragalot: RyanS: we've only used them up to 2m iirc
07:23 AM miss0r: fragalot: Yeah, I see you did good ;D But I have some vauge idea of what is going on ;)
07:23 AM fragalot: makes for a great press plate too
07:24 AM miss0r: :o
07:24 AM miss0r: hehehe
07:24 AM RyanS: fragalot: anodized aluminum rails?
07:24 AM miss0r: I should realy be making the baseplate in stainless steel...
07:24 AM fragalot: RyanS: yup
07:25 AM miss0r: As I will be using water to submerge it all the time
07:25 AM RyanS: durable?
07:26 AM RyanS: not sure I want to use Igus rails on the X and Y, but the Z sounds good
07:27 AM miss0r: :-/ I don't have the stainless stock that makes sense for this build. I'll go with corrosion resistant alu then. I have plenty of that in stock
07:27 AM miss0r: Alot less work anyway
07:28 AM fragalot: RyanS: no complaints so far, and they get used in very harsh environments
07:29 AM RyanS: aluminum also makes sense with a water table plasma
07:29 AM fragalot: yeah
07:31 AM * SpeedEvil ponders ice tables.
07:31 AM RyanS: not that a 45 amp plasma can cut all that fast anyway
07:32 AM RyanS: the water absorbs the plasma smoke that billows out with toxic smelling clouds
07:33 AM fragalot: absorbs some of it *
07:33 AM * SpeedEvil listens to the Orb.
07:34 AM RyanS: a lot of it judging from videos
07:35 AM RyanS: I would have a couple of exhaust fans in the shed roof
07:35 AM miss0r: I'm trying to chase down somewhere to buy some PEEK 60x60x200 massive stock :S
07:36 AM RyanS: ...and a gas mask
07:38 AM RyanS: damn, i'll have to test cutting over water. downdraft systems are massive
07:38 AM SpeedEvil: miss0r: https://www.ebay.co.uk/itm/PEEK-Rod-NATURAL-Round-Dia-Bar-High-Temperature-Engineering-Plastic-Long-Length/162545177620 $1K tho
07:38 AM SpeedEvil: (round 90mm * 250mm bar)
07:39 AM miss0r: SpeedEvil: Indeed. Finding round bar is not a problem :) I would just rather have it as square bar stock :D
07:39 AM RyanS: how mains current do EDMs need?
07:40 AM miss0r: RyanS: Depends on what EDM it is ;)
07:40 AM RyanS: much *
07:40 AM SpeedEvil: RyanS: tap burners can be nearly zero
07:40 AM SpeedEvil: Mostly proportionalish to volume of cut per unit time.
07:40 AM miss0r: SpeedEvil: unless you make it yerself, like I did... It heats the room as well :D
07:41 AM RyanS: one for forging currency
07:42 AM RyanS: I think they EDM counterfit rare coins'
07:42 AM miss0r: I hardly think that will make a profit :) but it all depends on how fast you want to do it. Material removal rate
07:43 AM miss0r: Sweet holy christ, that PEEK is expensive
07:43 AM SpeedEvil: http://k-mac-plastics.com/peek-square-rectangle-bar-stock.htm goes up to 1.5" square
07:43 AM RyanS: 1930 Australian pennies fetched $50k ten years ago
07:44 AM sync: you would most likely edm the stamp and then stamp the coins like they would have done when they made them
07:44 AM fragalot: miss0r: PEEK *IS* expensive.
07:44 AM RyanS: yeah I think thanks what they do
07:44 AM miss0r: No shit :D
07:45 AM SpeedEvil: 'you may not like it, but this is what PEEK expense looks like'
07:45 AM RyanS: it's micron accurate?
07:45 AM fragalot: SpeedEvil: do you even thrift, bro?
07:45 AM SpeedEvil: https://www.youtube.com/watch?v=v0ObtFpeQ-E - neat
07:46 AM miss0r: A client of mine just send me a drawing, of a test piece they want fabricated out'a the stuff... I found a local pusher for 80x300 PEEK roundstock. I will have to make it out'a roundstock, to keep delievery time down. That bar is ~$1000US
07:46 AM SpeedEvil: Phenolic 2-part foam, fire resistant and mostly non-toxic
07:46 AM SpeedEvil: I wish they had an online shop
07:47 AM RyanS: but I got the impression EDM somehow allows you to copy stuff?
07:47 AM SpeedEvil: RyanS: not any more than any other fabrication technique
07:47 AM RyanS: a pusher, lol
07:47 AM SpeedEvil: It can let you machine fine details in very small molds or dies
07:47 AM miss0r: SpeedEvil: Well, you could use an EDM to make it look like it was milled...
07:48 AM SpeedEvil: Milling almost seems easier
07:49 AM RyanS: "wassup blood, you got any PEEKz? I got paper bruv"
07:49 AM fragalot: SpeedEvil: that stuff is quite cool
07:50 AM RyanS: sorry I have been watching Top Boy, with all the London street slang
07:50 AM SpeedEvil: Similarity of test block shape to a star-trek logo entirely coincidental
07:50 AM fragalot: the consistent density is impressive
07:50 AM RyanS: it's The Wire but better
07:51 AM SpeedEvil: fragalot: I'm not sure if that's due to the material, or the clamped mold TBH
07:52 AM fragalot: has to be both
07:52 AM fragalot: but the fact they get an expanding foam to successfully fight gravity is neat
08:13 AM Beachbumpete1: Good Morning LinuxCNC
08:55 AM miss0r: fragalot: I just had to run through a storm of hungry hungry mosquitos to extract my mosquito magnet from the battlefield. A small nest of spiders had decided it was feeding time, and clogged up the intake of the machine, ate what they could & left, leaving the mosquito magnet unable to fend for it self. Now It should be operational again
08:56 AM fragalot: xD
08:56 AM miss0r: Atleast I hope... It is much needed at the moment
08:57 AM fragalot: i've decided to start working on a little reusable library for the most common things I do with my arduinos
08:57 AM fragalot: figured if I do this at work I may as well also do it for the stuff I use at home >.>
08:58 AM miss0r: :]
09:46 AM fragalot: miss0r: for your safe: https://www.youtube.com/watch?v=y3GAhpE3hLM
10:16 AM miss0r: fragalot: wide open safe, if someone tries to steal the content BAM, they a forced to wait for me to come how, wielding a crowbar :D
10:18 AM Loetmichel: miss0r: better trigger the co2 fire supreessing unit "by accident".
10:18 AM miss0r: :D
10:18 AM Loetmichel: no need for a crowbar then ;)
10:18 AM miss0r: b...but I like the crowbar :D
10:19 AM Loetmichel: crowbar is WAY to much paperwork afterwards
10:19 AM Loetmichel: and expensive to get the lawyers to get you away with declaring that a "self defense case"...
10:20 AM miss0r: keep in mind I live close to a swamp... its big enough that people can dissapear :D
10:20 AM miss0r: no paperwork then, ay? :]
10:22 AM fragalot: miss0r: :D
10:22 AM miss0r: Why hasn't the laser mosquito zapper not reached the market yet! ME WANTZ IT !
10:22 AM miss0r: http://www.wired.co.uk/article/intellectual-ventures-bug-zapper
10:22 AM fragalot: $$$
10:23 AM miss0r: I'll take a another loan in the house, if I have to :D
10:23 AM * miss0r wantzzz itzz !
10:24 AM fragalot: make one. :-)
10:25 AM miss0r: I need to have it. The wife says a large plexiglass dome over our house&garden is out of the question
10:25 AM fragalot: if price is not an issue, and neither is bystander safety, it's actually not that hard
10:25 AM miss0r: Indeed :]
10:26 AM miss0r: I'm also considering setting up some swallows nests, to attract them. They eat a metric shitton of small insects every day. I've heard they are quite effective
10:27 AM fragalot: nice to look at too
10:28 AM miss0r: indeed
10:29 AM fragalot: my red paint marker seems to have leaked when I shook it
10:29 AM fragalot: looks like i've got chicken pox >.<
10:29 AM miss0r: lol
10:39 AM MarcelineVQ: miss0r: if safety isn't an issue you could order in some deet barrels from offshore and roll them into the closest open-air water source
10:40 AM fragalot: lol
10:40 AM MarcelineVQ: that option aside bats eat the hell out of mosquitos so bat houses would be a good start if your area can suport them
10:40 AM fragalot: or if you want a fun option, i've got a collection of pretty damn accurate airguns
10:42 AM MarcelineVQ: my test bottle I cut on the lathe last night is already cracked all over from shrinkage, wood is a difficult material
10:42 AM MarcelineVQ: it doesn't help that it's cracking-prone wood of course
10:42 AM fragalot: slow down the drying process as much as possible
10:43 AM Loetmichel: MarcelineVQ: soak it in epoxy in a vacuum and turn it again.
10:43 AM Loetmichel: soaking BEFORE turning
10:43 AM fragalot: don't forget to let it dry
10:43 AM fragalot: :P
10:44 AM fragalot: well, harden
10:44 AM MarcelineVQ: hehe, well hopefully the wood I plan to use is less tempermental than these test pieces, will have to go pick up a test length of that stuff
10:45 AM MarcelineVQ: but it won't be kiln dried so the water content could be all over the place, we'll just have to see
10:46 AM fragalot: even if it's kiln dried it can be all over the place
10:46 AM MarcelineVQ: planning to use yellow cedar which is so full of oils it should be reasonmably stable if the ends at least are sealed
10:46 AM fragalot: depends on where that piece of wood was in the stack.

12:16 PM hazzy-dev: lcvette: Any progress?
12:16 PM lcvette: YES!
12:16 PM hazzy-dev: Hurray!
12:16 PM lcvette: I got it up and working
12:16 PM lcvette: windows was the issue
12:17 PM hazzy-dev: LOL, always :)
12:17 PM hazzy-dev: Running touchy?
12:17 PM lcvette: gmoccapy
12:17 PM hazzy-dev: good!
12:17 PM lcvette: windows was doing something funny to a handful of files and adding a xxx.ngc~ on the end
12:18 PM lcvette: and they would not come through to linux
12:18 PM lcvette: i went through and unblocked those files and renamed them without the ~ and all of a sudden things started happening
12:18 PM lcvette: tom caught it last night
12:19 PM lcvette: Tom_l: if your on big thanks for the catch!
12:19 PM hazzy-dev: Windows can wreck havoc with text files, wrong line endings etc.
12:19 PM lcvette: now i just have some normal quirks to iron out but those are not much different then the mach3 stuff im accustomed to
12:19 PM lcvette: yes indeed
12:20 PM lcvette: i learned my lesson
12:20 PM lcvette: from now on my buddy and i will share direct from linux to linux with no layover in windows boxes
12:20 PM lcvette: lol
12:23 PM IchGucksLive: hi all
12:31 PM lcvette: hi ichs
12:39 PM IchGucksLive: ;-)
12:45 PM JT-Shop: gotta love some of the emails I get "do you have a comprehensive hookup guide for (insert something here)
12:47 PM IchGucksLive: JT-Shop, emails to lauph ROFL
12:47 PM IchGucksLive: JT-Shop, is linuxcnc a mashine Brend
12:48 PM IchGucksLive: JT-Shop, where is the shop i cand find it (Lcnc)
12:51 PM fragalot: lcvette: the ~ at the end of the file is windows' way of "locking" the files when they are opened
12:52 PM fragalot: really annoying behavior imho
12:54 PM lcvette: yeah i didn't even open them
12:54 PM IchGucksLive: lcvette, what is a xxx.ngc
12:54 PM lcvette: he must have to review them before sending them over on his windows box not knowing the havoc it would cause
12:54 PM IchGucksLive: a mdi command
12:54 PM IchGucksLive: a subroutine
12:54 PM lcvette: macro file used in a remap for the ATC command
12:54 PM IchGucksLive: ok
12:55 PM lcvette: they are working now
12:55 PM lcvette: somewhat
12:55 PM lcvette: lol
12:55 PM IchGucksLive: you got alot solved from where you came 2weeks ago
12:55 PM lcvette: indeed
12:55 PM lcvette: i think i have aged 5 years inthose 2 weeks
12:56 PM IchGucksLive: thats the prie we alll face
12:56 PM IchGucksLive: price
12:56 PM SpeedEvil: https://rotorcraft.arc.nasa.gov/Publications/files/Balaram_AIAA2018_0023.pdf Not really on topic, but it has linux, FPGA ASIC, optical feedback, and will be a couple of kilo helicopter on Mars.
12:57 PM IchGucksLive: SpeedEvil, wondering homany lcnc mashines on nasa running
12:57 PM SpeedEvil: :)
12:57 PM IchGucksLive: i know at least 4 from Burningman people
12:57 PM SpeedEvil: FOIA!
12:57 PM SpeedEvil: (not really)
12:58 PM IchGucksLive: im off today will go to the USA thuseday 2 day WA
01:00 PM IchGucksLive: lcvette, reading the logs saying i dont own a MS Pc since 2008 all Linux
01:07 PM phipli: JT-Shop, http://elephantandchicken.co.uk/projects/LittleEngine/index.html
01:10 PM JT-Shop: bicycle engine?
01:10 PM gloops: https://www.ebay.co.uk/itm/Proxxon-Milling-Machine-Might-be-complete-or-as-for-spare-parts-Metalworking/292569172687?
01:10 PM phipli: JT-Shop, yup
01:10 PM JT-Shop: cool
01:11 PM * JT-Shop goes back to bathroom destruction
01:11 PM phipli: gloops, "might be complete"
01:11 PM gloops: wonder what the xy table is like, id throw the post away anyway
01:11 PM gloops: i doubt thats useable for metal
01:13 PM fragalot: I doubt that's usable, period
01:14 PM fragalot: that's nothing more than a micro drill press with XY table
01:14 PM jthornton: phipli: found this during my lunch minute, not had time to fiddle much with it https://paste.ubuntu.com/p/WDpcWN5Fb5/
01:14 PM gloops: no i dont think i could bring that into my stable of distinct machines
01:15 PM phipli: jthornton, https://www.rapidtables.com/web/tools/svg-viewer-editor.html
01:16 PM JT-Shop: cool
01:20 PM phipli: JT-Shop, that is a better way of doing the plot line
01:21 PM phipli: I looked at doing something similar, but ended up stealing some old code from an older project...
01:21 PM phipli: but you're right, a lot more elegant than my bodge :)
01:31 PM Tom_itx: sounds like lcvette will be breakin cutters before too long
01:34 PM Tom_itx is now known as Tom_L
01:35 PM JT-Shop: phipli: seems everything you find with a google search uses js or some bloated library\

02:16 PM phipli: heh
02:17 PM miss0r: fragalot: I almost bought a conversion kit for my camm-3 PNC-3100 cnc mill, so that I can run it with linuxcnc. But as it turns out, the guy selling the convertion kit, made it for the PNC-3000 model, which is surprisingly dissimular, when it comes to the controller... SUCKS!
02:18 PM fragalot: >.<
02:18 PM fragalot: ask him if he can adapt it to work with the 3100?
02:18 PM fragalot: or is it /completely/ different?
02:19 PM miss0r: well, his design is a pcb, with a few micro controllers on it, that is slottet in, instead of an existing controller. My controller does not have that controller, not any ICs in slots...
02:20 PM miss0r: so, somewhat different, yeah
02:21 PM miss0r: enough so, that at the very least, its not a plug-in solution anymore
02:22 PM miss0r: but the machine is simple enoug- if I could do without the build-in control panel, which I easily could, it should not be that hard to make a new controller for it. But if I do so, I can't use the proprietary software anymore, and it 'does' have its advantages in some cases
02:23 PM fragalot: what does it have that linuxcnc does not offer?
02:24 PM miss0r: nothing. but it does have some convenient CAM software, for when you want something done, without thinking too much about what you are doing
02:25 PM fragalot: so a "conversational" interface
02:25 PM fragalot: http://linuxcnc.org/docs/html/gui/ngcgui.html <= /totally/ the same thing.
02:26 PM fragalot: shouldn't take you much more than a few weeks
02:26 PM fragalot: :P
02:26 PM miss0r: hehe. The convertion kit was nice, because it changed between the two interfaces at the flip of a switch, and it is only $72 us
02:27 PM miss0r: but that doesn't help me much, if it does not fit ;)
02:27 PM fragalot: ._.
02:27 PM miss0r: I made that face exactly, when I found out
02:28 PM fragalot: lol
02:29 PM miss0r: On other news: I've decided to make two stands for the EDM; one perfectly vertical, over a nice flat table, the other is a magbase, with all sorts of ajustments. The vertical one is ment to be used here, in house. The other on the go. The idea being that the linear sliding system, should be able to attach to either, without too much work
02:29 PM fragalot: isn't it easier to leave the mag base on at all times?
02:30 PM miss0r: fragalot: Sure, but if I want to use it for anything other than burning out taps, it would be nice to have something a bit more rigid & precise to work off
02:31 PM fragalot: so you're going to make a second unit then?
02:31 PM fragalot: because you'll never dismount it from the previous setup :P
02:31 PM miss0r: lol
02:31 PM miss0r: I'm hoping it can be done in an easy fashion.
02:32 PM fragalot: main thing is going to be how easy it is to tram in on both setups
02:32 PM miss0r: I'm wondering if I should run out and buy one of those chinesium cross tables, to hold the tank
02:32 PM miss0r: I'm hoping to be able to machine the stationary system, so that it does not need tramming
02:33 PM fragalot: ha. :P
02:33 PM fragalot: everything needs to have the ability to tram it in
02:33 PM miss0r: well, sure. But lets say I accept a tolerance of 0.1 degree or so, then I should be more than fine
02:34 PM miss0r: (plus some hidden ajustment screws) :P
02:34 PM fragalot: so the magbase is acceptable after all then? :D
02:34 PM fragalot: about that cross table - I wouldn't.
02:34 PM fragalot: if you're moving the tank, that's going to be a fair amount of weight for a china XY table
02:34 PM miss0r: The inside of the PNC-3100 controller: https://imgur.com/a/dB7cm6J
02:35 PM fragalot: and they aren't the most rigid to begin with
02:35 PM miss0r: that is true..
02:35 PM fragalot: y'know..
02:35 PM fragalot: those look like L298N drivers on top
02:36 PM miss0r: Probally is
02:37 PM fragalot: so.. those SN74LS07N chips are probably sending the step/dir signals
02:37 PM fragalot: which means that it should be possible to intercept & replace :P
02:38 PM miss0r: No doubt :] But no matther how you slice'n dice it - its a hellova lot more work, than the plugin
02:38 PM miss0r: and if it is not that straight forward, I won't do the convertion any time soon, in fact, I'm not sure I will ever get around to it
02:39 PM fragalot: yeah it's not a plug'n'play solution by any means
02:40 PM miss0r: which brings me back to: ._.
02:40 PM miss0r: The machine itself is quite solid. I should realy get around to doing this at some point
02:41 PM fragalot: still only a matter of a breakout board + drivers
02:41 PM miss0r: The smallest cross section of the round linear rails is 20mm. The vertical ones are 35mm. All ballscrews ect..
02:41 PM fragalot: if an L298N suffices, it's cheap, but lots of time
02:42 PM fragalot: oh wow
02:42 PM miss0r: yeah.. its a heavy bastard
02:43 PM miss0r: the manual says it weighs in at 52kgs
02:43 PM miss0r: No wonder I had a hard time lifting it to the workbench, just before :D
02:44 PM fragalot: hehe
02:44 PM miss0r: This machine could become truly sweet if I made a linuxCNC compatible controller and replaced the spindle with something a bit more beefy
02:45 PM fragalot: or the EDM
02:45 PM miss0r: don't worrie, this project will not be pushed in before the EDM is complete ;)
02:45 PM miss0r: woah.. this thing only has a 180watt spindle
02:45 PM miss0r: No wonder I feel like it runs out of power quickly
02:45 PM fragalot: well,.. it IS an engraver
02:46 PM fragalot: not really meant for over 2mm V-bits
02:46 PM miss0r: thou shall shut yer' trap! its a milling machine :P
02:54 PM gloops: 800w spindle is ok - look at a typical hand drill, 500w? you can drill half inch holes in girders with one
02:55 PM fragalot: they tend to smell a bit funny if you do that for any extended period of time
02:57 PM gloops: yeah but a 2mm ballnose shaving ally isnt anything like that
02:57 PM fragalot: sure
03:00 PM gloops: <MarcelineVQ> for anyone interested I made a couple (amateur) of vids of my wood lathe cnc adaptor https://www.bitchute.com/video/V0d0S4p7FVAg/ https://www.bitchute.com/video/GGlaD6spZRW5/
03:00 PM gloops: still not able to watch these, just freezes after a few seconds
03:02 PM SpeedEvil: gloops: 800W at a much, much higher speed though
03:02 PM SpeedEvil: So much lower torque
03:02 PM gloops: also, 500w drill has my arms behind it
03:03 PM gloops: but yes SpeedEvil, these chinese spindles are made to last
03:03 PM SpeedEvil: three or four minutes.
03:04 PM gloops: 1 year seems typical, in day to day production
03:04 PM gloops: then you decide whether to bother changing bearings
03:04 PM SpeedEvil: Not a lot to go wrong in a not grossly overloaded brushelss motor
03:07 PM gloops: actually mine came with 2 year guarantee
03:10 PM fragalot: gloops: shame that's already passed long before you got the mill up? :P
03:10 PM gloops: not quite ive got a year left
03:11 PM gloops: its about 1 year since i started, built 2 machines in that time
03:12 PM gloops: and..the time was mainly down to my total and utter insistence on excellence
03:13 PM gloops: could easily have done it in a third of the time, but i did not give in to any thoughts of cutting corners at the expense of greatness
03:15 PM SpeedEvil: Isn't cutting corners pretty much the point of most spindles?
03:16 PM gloops: the proof is in the pudding, fast...pixel perfect cutting and carving
03:16 PM miss0r: gloops: Are we talking early '80 video game pixels here? or?
03:17 PM fragalot: TRS-80
03:17 PM gloops: i will post pics soon, maybe later this week, im off next week anyway
03:18 PM miss0r: Still waiting for those overview pictures of the perfection ;)
03:19 PM gloops: ill post, im satisfied with the build now
03:19 PM fragalot: until you do we're all just assuming you're making it all up
03:19 PM miss0r: Glad to hear :] Looking forward to them still ;)
03:20 PM miss0r: fragalot: People have some very vivid dreams, lying on their back in an opium denn
03:20 PM gloops: i dont look at it much, but i looked at the gantry from the side yesterday, a lot of people would be surprised just how much work there is in this machine
03:20 PM miss0r: fragalot: Even lying face down ;P
03:21 PM gloops: aesthetics wasnt my goal, but i have managed to capture a kind of brutalist 1940s appearance married with perfect functionality
03:22 PM miss0r: sounds like a new centerpiece at the Louvre
03:28 PM CaptHindsight: like my grandma used to say "you meet a lot of weirdos on the internets"
03:29 PM miss0r: smart woman, your grandma
03:31 PM gloops: pretty common take on intellect
03:32 PM gloops: #BREAKING Marseille shooting: Hooded men open fire with Kalashnikovs https://bit.ly/2rWnZVE
03:32 PM gloops: that wasnt on the news
03:32 PM fragalot: again?
03:33 PM gloops: ive just had TV news on for an hour, no mention
03:33 PM gloops: maybe no casualties
03:33 PM fragalot: or a more sensible thing: a media black-out
03:34 PM fragalot: which isn't going well, if that is the case :P
03:34 PM gloops: could be gang stuff, not terrorism
03:34 PM fragalot: likely is.
03:36 PM gloops: UK govmt announces plans to unleash AI to counter cancer and other diseases
03:36 PM gloops: youll be informed you have cancer before you know anything is wrong
03:38 PM gloops: machines will scan dna, medical records, family tree etc + social media to make early diagnosis
03:40 PM fragalot: good job you left the EU so that it's possible to legally combine that data
03:42 PM gloops: would the EU prevent it? claims 1000 lives a year will be saved
03:44 PM fragalot: well given that it's a small stepping stone for insurance companies to use that same AI data to raise your fees, probably.
03:45 PM fragalot: That said, the use of the AI technology on singular data like X-rays, is perfectly fine
03:46 PM SpeedEvil: gloops: AI at the moment is utterly shit and overhyped in many cases for medical conditions.
03:47 PM SpeedEvil: In other than very, very narrow realms, it is overpromised to the point of ridiculousness.
03:47 PM SpeedEvil: Same for pretty much every genetic risk factor, other than a bare handful.
03:47 PM SpeedEvil: They are statistically interesting, but useless for particular patients.
03:50 PM SpeedEvil: https://www.coyneoftherealm.com/blogs/mind-the-brain/creating-ted-talks-from-peer-reviewed-growth-mindset-research-papers-with-colored-brain-pictures - somewhat relevant
03:50 PM gloops: im not sure how this goes beyond using databases to flag up high risk cases
03:51 PM SpeedEvil: It almost doesn't.
03:52 PM SpeedEvil: The problem is there are lots of breathlessly written abstracts of papers that promise great results whih when you dig into their actual patient related results might as well have been null.
03:53 PM gloops: https://www.eteknix.com/uk-announces-plans-use-ai-detect-cancer/
03:53 PM gloops: 22000 lives a year saved
04:02 PM rmu: there are probably lower hanging fruit in the uk health system if you want to save 20000 lives per year
04:02 PM XXCoder: in usa fruit is much much lower
04:02 PM XXCoder: its called adding one payer system health insurance
04:05 PM gloops: cancer treatment is expensive though
04:05 PM XXCoder: somehow, other countries manage.
04:05 PM XXCoder: its total mystery
04:08 PM gloops: i think smoking is on the decline here now, cigs almost £10 for 20
04:08 PM gloops: whats that about 12 dollars
04:08 PM XXCoder: theres many causes of cancer
04:08 PM XXCoder: also reason theres no secret cure to cancer
04:09 PM XXCoder: fucking natural news
04:10 PM gloops: well, survival rates are well up, there is no pill or tonic for all cancer, but combined measures for prevention, early detection and so on, your chances will be pretty good soon
04:11 PM XXCoder: except its huge amount of debt, if live in usa
04:12 PM gloops: i dont really understand how it works in the usa, all i know is the nhs
04:14 PM XXCoder: remove public health insurance, make medicine and procures 10x price
04:14 PM XXCoder: and you get beganning of it
04:14 PM XXCoder: some medicine is insane. isulin for example, its 100x more than prices at say canada
04:15 PM XXCoder: the allegric respondant medicine (epen?) costs $600 each here, it used to cost $30 for 2
04:15 PM gloops: yes but youre insured
04:15 PM XXCoder: hope that post-expired medicine still works
04:16 PM XXCoder: lol insurance is meaningless
04:16 PM rmu: you can go to an ER and they have to treat you, right?
04:17 PM XXCoder: why is this a solution?
04:17 PM gloops: if you pay your insurance, you get treatment, surely thats how insurance works
04:17 PM XXCoder: and still gain huge debt,
04:17 PM XXCoder: its this bad
04:18 PM XXCoder: #1 reason for bankruptacy in usa is medicine bills.
04:22 PM gloops: well, my mate went to america for a holiday, his son got poorly while they were there, just upset stomach, he said it was a bit scary he had to show his bank card at the reception lol
04:24 PM gloops: we dont pay here, nothing at all just NI contributions, many americans say the service isnt good enough here, we have waiting lists and so on, but it works ok for most
04:24 PM XXCoder: hopefully not huge debt
04:25 PM XXCoder: I read about one canadian who went into usa for tourism, suddenly had labor pains
04:25 PM gloops: you cant get any debt, its totally free at the point of delivery
04:25 PM XXCoder: her new debt was 300k
04:25 PM gloops: you pay a surcharge for prescription medicine, i dont even know what it is 10 maybe £14 i havent had any for many years, thank the lord
04:26 PM SpeedEvil: Also, even non prescription meds can be _lots_ cheaper.
04:26 PM XXCoder: indeed. im not aginst profit
04:26 PM XXCoder: but im against 1000% markup
04:27 PM SpeedEvil: Sudafed bought without NHS subsidy can be much, much less expensive than in the USA
04:27 PM SpeedEvil: err
04:27 PM SpeedEvil: ventolin/salbutamol even
04:27 PM SpeedEvil: https://www.nytimes.com/2013/10/13/us/the-soaring-cost-of-a-simple-breath.html
04:27 PM asdfasd: any idea why I get error message at #5422 ? linuxcnc version 2.4.3
04:27 PM XXCoder: nowdays im more and more against for=profit health system period rather than super price inflation
04:28 PM gloops: asdfasd when does this error show?
04:28 PM asdfasd: gloops: when loading G code file
04:29 PM asdfasd: #500 = #5422
04:29 PM asdfasd: G0 Z2
04:29 PM gloops: is this something that was working ok before? not new cam software or something like that?
04:29 PM asdfasd: it is giving error for the next line but it is caused by #5422
04:30 PM asdfasd: it is first test, I doubt it ever been working
04:31 PM asdfasd: when I replace #5422 with random single digit 1 it does work
04:31 PM rmu: does it work with #<_z>
04:31 PM gloops: cant be any reason z2 is impossible
04:33 PM rmu: asdfasd: i think you have to write #500 = [#5422]
04:33 PM asdfasd: #<_z> is not recognised either
04:33 PM asdfasd: [#5422] give same error as before
04:34 PM rmu:  marks an expression
04:35 PM rmu: what error message do you get
04:35 PM gloops: pretty scary re USA medicines
04:36 PM asdfasd: the error is for the next line of g code "parameter number out of range"
04:38 PM asdfasd: probably 2.4.3 is old version, but I really dont want to upgrade
04:39 PM rmu: asdfasd: have a look at online dox here http://linuxcnc.org/docs/2.4/html/gcode_overview.html#sub:Numbered-Parameters i don't really find parameter 5422
04:39 PM XXCoder: ow. reading about guy who used gympie gympie leaf as ass wiper
04:40 PM XXCoder: he apparently evenuallu shot himself to death
04:40 PM asdfasd: 5422 is on a different page
04:40 PM asdfasd: http://linuxcnc.org/docs/html/gcode/overview.html
04:40 PM asdfasd: #<_z> - Return current relative Z coordinate including all offsets. Same as #5422.
04:41 PM Deejay: gn8
04:42 PM rmu: asdfasd: but the documentation you are referring to is for latest (2.7) or even development version
04:43 PM gregcnc_: http://linuxcnc.org/docs/2.4/html/gcode_overview.html
04:43 PM gregcnc_: "Notes: The global parameters _a, _b, _c, ... _z have been reserved for special use. In the future, they may provide access to the last Aword, Bword, Cword, etc. "
04:44 PM gregcnc_: OH I"m a bit late
04:44 PM asdfasd: I see.... so in 2.4 version is not possible to get current z position?
04:46 PM gregcnc_: appears to have been implemented in 2.5
04:47 PM asdfasd: :(
04:47 PM asdfasd: it seems that I have to upgrade.....
04:48 PM asdfasd: anyway, thanks all for the help
04:58 PM asdfasd: I think I found the solution
04:58 PM asdfasd: for 2.4 is not 5422, but it is 5063
04:59 PM asdfasd: After successful probing, parameters 5061 to 5069 will be set to the coordinates of X, Y, Z, A, B, C, U, V, W
05:04 PM gloops: excellent
05:20 PM rmu: asdfasd: thats the same with 2.7
05:21 PM rmu: asdfasd: 5422 should contain _current_ z-axis
05:22 PM rmu: 5063 will contain z value where probe made contact
05:26 PM asdfasd: not sure yet
05:26 PM asdfasd: the G code loaded properly and the probe cycle run properly
05:27 PM asdfasd: but didnt continue with cutting, so not sure yet if that is the same
05:27 PM rmu: 5063 in 2.7 and 2.4 is the same parameter
05:29 PM asdfasd: Im not sure but I think 5422 = 5083 + tool compensations
05:29 PM asdfasd: so if I dont have tool compensations they must be equal
05:30 PM asdfasd: let me run it again to see if ot works properly
05:30 PM Maru: Hi Guys, I am Maru from switzerland. Sorry for my english, it is not my motherlanguage...
05:30 PM rmu: why on earth should #5422 be #5083 (you mean 5063?) plus tool comp?
05:31 PM asdfasd: I read it somewhere in docs that 5422 include some compensations
05:31 PM rmu: 5063 records z position when you do a G38 probe where probe made contact
05:31 PM asdfasd: but not sure
05:32 PM rmu: if you do G38.3, then indeed 5063 contains current z value, because motion will stop at contact
05:32 PM rmu: (not retract)
05:32 PM asdfasd: then what is the difference between 5063 and 5422 ?
05:32 PM rmu: if you probe and retract, tool is where it was before
05:33 PM rmu: 5422 contains what your readout shows as current z position
05:33 PM rmu: always
05:33 PM rmu: but only on version >2.5 it seems ;)
05:33 PM asdfasd: I see
05:34 PM rmu: you didn't say what you wanted to achieve in the first place
05:35 PM asdfasd: I wanted to run G code generated from autoleveller
05:35 PM asdfasd: PCB auto level
05:35 PM asdfasd: here is 1 cycle
05:35 PM asdfasd: G0 X27 Y207
05:35 PM asdfasd: G38.2 Z-1 F100
05:35 PM asdfasd: #500=#5063
05:35 PM asdfasd: G0 Z2
05:35 PM Maru: i have follow problem: I have an old BF20-CNC milling maschine (buy in ebay), work with an MACH2 application on WinXP. I dont want an WinXP-computer in my network, so i will use LinuxCNC to work with this maschine. I can see the referenz-sensors, i can see the emergency-power off. but i can not jogg the axis. my question is: when i can see the reference and the emergency switch, the parallel-port-card have the right adress, right?
05:36 PM Spirit532 is now known as Guest64228
05:36 PM Spirit532__ is now known as Spirit532
05:36 PM CaptHindsight: Maru: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester
05:37 PM Maru: thx ;) i will try it.
05:37 PM CaptHindsight: Maru: you can toggle the different IO pins to see
05:38 PM rmu: asdfasd: looks plausible... so it records z value of contact with PCB in #500
05:38 PM Maru: yes, i will try. need little bit of time, because other computer...
05:47 PM asdfasd: it seems to work with 5063
05:48 PM asdfasd: after probing the correct values are stored in #500 and so on
05:55 PM gloops: Maru switch the power on, then hit the button next to it
06:01 PM Maru: ok, the parallel port works... i see my referenz-switches, when i press it
06:02 PM Maru: @gloops: what you mean? this two buttoms in the left top of the window? yes, i do it
06:03 PM Maru: but the steppers dont move.
06:03 PM gloops: yes
06:03 PM gloops: hmm, thats inconvenient
06:04 PM CaptHindsight: Maru: check the wiring, power and polarity of the Step and Dir signals
06:04 PM gloops: you set the correct pins in stepconfig?
06:04 PM Maru: if the configuration of the steppers is wrong (i think it is right, because i import the mach-config, but anyway), i will see a reaction on the steppers (brumming or something. but i see nothing...
06:05 PM Maru: with MACH2 all works, so i think the wiring is OK. i import the config from MACH2, when i make the stepconfig, but i not confirm it with the wirng diagram
06:05 PM Maru: i will check this
06:06 PM Maru: the breakout-board is really old, i find nothing about this in the internet. it is a business MX 2.0
06:06 PM CaptHindsight: Maru: check the polarity of Step and Dir
06:07 PM gloops: well if it all works with mach that pretty much eliminates the wiring, seems to be config thats wrong
06:08 PM gloops: i would run a new stepconfig and input the values yourself
06:08 PM Maru: ok, i will try
06:09 PM Maru: my goal is to morning i see a movement... so i can go sleep with peace in mind :)
06:10 PM gloops: oh youll get that going no problem
06:25 PM Maru: when i config the axis and want try test the config, it come an IO-Error (broken pipes)
06:25 PM Maru: anybody knows, what mean?
06:27 PM Maru: Erno 32,
06:31 PM CaptHindsight: Maru: please post you config.ini and hal.ini on pastebin.ca or similar
06:31 PM CaptHindsight: you/your
06:32 PM Maru: ok, i will do, one moment
06:33 PM Maru: i open this RIC now on the Linux-machine near the milling machine. its more easy. one moment. thank you for help!
06:35 PM maru_on_milling_: ok, i am an the maschine. what file you need?
06:37 PM maru_on_milling_: ok, i will go back and look
06:45 PM maru_on_milling_: here the .hal
06:45 PM maru_on_milling_: http://pastebin.ca/4031115
06:46 PM maru_on_milling_: here the .ini
06:46 PM maru_on_milling_: http://pastebin.ca/4031118
06:51 PM maru_on_milling_: the parallel port card (LPT-card) have two adress 0xec00 and one in "()" clamps (0xe880) but only on the first one i see the reference-switches
06:52 PM maru_on_milling_: is here the problem?
06:52 PM maru_on_milling_: in winXP (the same computer) this card work. in linux i think it work too, but i dont understand, why have two adress...
06:55 PM maru_on_milling_: it is a startech PEX1P (PCI-Express)
06:56 PM JT-Shop: often a pci parallel card will have several addresses and you have to sort out which one is the "real" address
06:57 PM maru_on_milling_: the terminal show me this:

07:39 PM lcvette: does anyone have a preference on using hard limit switches over single home switches and soft limits?
07:39 PM hazzy-dev: LOL, I was just cutting the grass with an old unmuffled B&S mower and I guess the neighbors thought they'd finally had enough and brought over a really nice almost new Honda and said, "please keep it"
07:39 PM lcvette: NICE!
07:40 PM lcvette: now take the muffler off the honda and put a big open header on it
07:41 PM lcvette: lol
07:41 PM hazzy-dev: Yeah, I think they might want to give me a prius next! :D
07:41 PM lcvette: when you see them tell them i9t really purrs now!
07:41 PM hazzy-dev: LOL, very tempting!
07:47 PM lcvette: hazzy-dev: do you use software limits?
07:48 PM hazzy-dev: Yes, soft limits and a single proxy sensor for homing
07:48 PM lcvette: pretty reliable?
07:49 PM hazzy-dev: Yes very, but I would only suggest that for stepper machines, on the server machine I have done I like full interdependent limits and home setup
07:50 PM lcvette: ah
07:56 PM lcvette: so interdependent meaning i can't share a home and limit switch signal for each axis
07:59 PM lcvette: well bugger
08:20 PM * hazzy-dev was eating
08:21 PM hazzy-dev: Yes, you can share signals, but for servo systems I like to have both home and limit switches
08:21 PM hazzy-dev: Sharing the signals is fine
08:22 PM hazzy-dev: I like having the limit switches kill all power, like estop does
08:25 PM hazzy-dev: The reason for this is if a servo drive fails closed the motor will run at full speed/torque and can do some real damage (I know from experience ...), so the limit switch should be hooked up to kill power to the drives
08:25 PM Roguish: axes end limit switches should inhibit motion via direct link to drives, in the direction of violation, still allowing 'back off' of switch.
08:26 PM Roguish: doesn't have to kill power, just disable, and maybe put into braking mode.
08:27 PM Roguish: yes a run away motor can blow the table right off...... very ugly.
08:27 PM hazzy-dev: Roguish: If the drive fails closed disable does not do anything, that is why I like to have the limits kill all power
08:28 PM Tom_L: lcvette, my home and limit are the same switch
08:29 PM Tom_L: but i have an offset for home just off the switch
08:30 PM hazzy-dev: I watched a ball screw be pulled until it broke in tensile due to a failed servo drive ..
08:30 PM hazzy-dev: Tom_L: That is fine for stepper machines, that is what I do for steppers too
08:30 PM hazzy-dev: Steppers can't run away!
08:30 PM Tom_L: i see
08:31 PM Tom_L: yeah i don't suppose he want's to keep buying linear trucks
08:35 PM skunkworks: we have 8tons of cutting force. or maybe it is 16tons... I don't remember. we have dedicated limit switches that kill power to the servo.
08:36 PM hazzy-dev: The likelihood of a servo drive failing is very low, so having limits kill all power is probably over kill (and very few machines have the limits set up that way), but it can't hurt. The only inconvenience is having to back off the limits by hand, but if homes are working properly then you should rarely hit the limits
08:37 PM hazzy-dev: skunkworks: That is some impressive cutting force!
08:38 PM skunkworks: big ball screws - big servos

08:40 PM skunkworks: 40 ft-lbs peak
08:41 PM skunkworks: (peak from the drives.. I think these servos are good for like 70ft-lbs
08:52 PM hazzy-dev: Am I seeing right, 115A max current, 15.2A continuous on the servos? Yikes!!!
08:54 PM flyback: *CANUCKED**CANUCKED**CANUCKED**CANUCKED*
08:58 PM lcvette: oh man
08:58 PM lcvette: now im worried
08:58 PM lcvette: lol
08:59 PM flyback: that
08:59 PM lcvette: so i need to run my limits to something other than linuxcnc?
08:59 PM flyback: sis what resettable fuses etc are
08:59 PM flyback: for
08:59 PM lcvette: to the servo drive inputs
09:00 PM flyback: AND YES THERMAL FUSES ALL YOU NOOBS
09:00 PM flyback: THERMAL FUSES SAVE LIVES, MOTORS, AND HOUSES
09:01 PM lcvette: Tom_L: thank you for that catch on the ~
09:01 PM lcvette: you nailed it
09:01 PM lcvette: solved the problem.. after that i stayed up til 4am fixing files and debugging and finally got gmoccapy to post up
09:03 PM lcvette: skunkworks: my servos are not nearly that strong..lol but they are big enough to cause some damage im sure they are 1.8kw 6nm 110mm on X and Y and 2.6kw 130mm 10nm on Z
09:03 PM lcvette: 32mm ballscrews I believe
09:54 PM pcw_home: speaking of firephotos: https://www.youtube.com/watch?v=FolI8jw_ZS4
10:22 PM hazzy-dev: woah, and I thought old faithful was impressive
10:23 PM Tom_L: i bet that's a sight at night
10:32 PM MarcelineVQ: sure is easy to forget we're sitting on a paperthin shell over a sea of screaming planetblood
10:32 PM Tom_L: until it gets a paper cut
10:33 PM MarcelineVQ: my house feels cold, let's go frakking in yellowstone
