02:43 AM MrSunshine: setp hm2_7i92.0.gpio.001.is_output 1
02:43 AM MrSunshine: net amp-enable <= halui.machine.is-on => hm2_7i92.0.gpio.001.out
02:44 AM MrSunshine: would that be correct to make the gpio pin 1 turn on when machine is on ?
02:44 AM MrSunshine: when i press the on button in axis
02:51 AM -!- #linuxcnc mode set to +v by ChanServ
02:52 AM randy: morning
02:54 AM randy: MrSunshine: you can check with the hal configuration tool, where you "watch" the pin states
02:59 AM MrSunshine: yeah gonna do that as soon as i get out into the shop, but one has to be brave to turn on the machine with a new motion control board in it =)
02:59 AM MrSunshine: alot of work later if i twist the gantry out of square :P
03:30 AM randy: you dont neet to connect the maschine for the first test run :)
03:31 AM randy: but i had a similar issue when i tested my 7i92 board the first time
03:31 AM randy: homing worked. motors running in the right direction. limit switches switched.
03:31 AM randy: manually stepping via buttons worked.
03:33 AM randy: homing with the machine enabled/motors connected (first homing was without motors enabled) - homeing z workd, homing x - no motor movement, homing y - full speed driving, gladfully stopped by limit y, otherwise i think the machine would be exploded :)
03:33 AM randy: maybe for the next time i will disconnect the ball nuts, not allowing movement :>
03:40 AM Deejay: moin
03:45 AM MrSunshine: gah stupid irc client doesnt save history ... :/
03:48 AM MrSunshine: ah there we are =)
04:47 AM Tom_L: morning
05:04 AM JT-Cave: morning
08:12 AM MrSunshine: hey JT-Cave, so ive got the machine up and running by hand coding the last part with the sensors etc but i sure can look at your program and see if i find bugs etc in the future also =)
08:12 AM MrSunshine: almost twisted the gantry out of square due to some scaling faults tho .. and the spindle wasnt easy to get going :P
08:12 AM MrSunshine: now im getting following error so increased the FERROR by an order of 10 and they disapeared for the moment atleast
08:14 AM JT-Cave: I'm working on the inputs now and it's a bit of a mess with naming
08:16 AM MrSunshine: how do you figure out the optimal timings for the dir setup etc for the driver .. HSS57 but no info in datasheet about that :/
08:17 AM perry_j1987: https://forum.linuxcnc.org/38-general-linuxcnc-questions/43660-t60-stepper-driver-and-hss57-motor-problems-solved
08:20 AM perry_j1987: says he attached the info to bottom of that thread
08:21 AM MrSunshine: the drives are supposed to tae up to 200khz signal
08:22 AM MrSunshine: oh those datasheets! thanks perry_j1987
08:25 AM perry_j1987: np
09:47 AM JT-Cave: pcw--home, what is the default firmware for the 7i76e?
10:16 AM pcw--home: 7i76e_7i76
10:30 AM MrSunshine: https://snipboard.io/r5b8Wl.jpg in this diagram, what would be direction hold and direction setup ?
10:31 AM MrSunshine: i guess direction setup is the >5us at the start then 6us at release
10:31 AM MrSunshine: but direction hold ?
10:56 AM pcw--home: set them both to 20000
10:58 AM pcw--home: There is basically no performance loss with large direct setup hold time settings so no reason to not use massive overkill
10:58 AM pcw--home: s/direct/direction/
11:03 AM MrSunshine: im getting following errors like crazy with the mesa card, what can this be due to ? i cannot at all reach same speeds as i had with the parport on the pc ...
11:04 AM MrSunshine: i guess its the FERROR and from JT-Cave:s config tool they were set to 0.0051 atleast got somewhere if i set it to 0.051 insted
11:11 AM pcw--home: if that's mm, .005 is too small
11:12 AM pcw--home: also you can set it smaller if you have the DPLL setup properly
11:33 AM MrSunshine: pcw--home, yes its mm but i guess JT-Cave has messed up the units somehow then ? =)
11:34 AM MrSunshine: would be 0,13 in metric if its inches that has been set
11:41 AM MrSunshine: 320 steps/mm gives 0.003125mm/step
12:08 PM JT-Cave: hmm looks like I have the ferror backwards
12:09 PM pcw--home: the ferror limits should be scaled appropriately depending on machine units
12:10 PM MrSunshine: finding bugs for JT-Cave like crazy here :P
12:10 PM JT-Cave: just a few lol
12:10 PM JT-Cave: pcw--home, 7i76e_7i76x1D.bit?
12:11 PM pcw--home: Yes
12:11 PM MrSunshine: i know how it is, wrote a program for my work before ... it never crashed when i used it so i handed it over to the boss and he in 5 seconds flat managed to make it crash :P
12:11 PM XXCoder: pointy haired boss magic
12:12 PM MrSunshine: developers themselves know how to avoid the bugs and do stuff in the same order each time they test stuff, so many bugs doesnt get found =)
12:13 PM JT-Cave: yup
12:15 PM JT-Cave: thanks
12:21 PM roycroft: phbs are generally good at triggering edge conditions quickly
12:31 PM JT-Cave: MrSunshine, I just bumped the version now I'm tired and it's overcast so time for a nap
12:52 PM roycroft: it's overcast here as well today, but at least none of that nasty sleety stuff
12:52 PM roycroft: or even rain
12:52 PM roycroft: at the moment
12:53 PM roycroft: our mail servers are being hammered today
12:54 PM roycroft: i just added some access list rules about a minute ago:
12:54 PM roycroft: 400 deny ip 5.34.207.0 0.0.0.255 any log (38467 matches)
12:54 PM roycroft: that's a network in ukraine
12:54 PM roycroft: 470 deny ip 49.0.0.0 0.255.255.255 any log (1977 matches)
12:54 PM roycroft: and that's a big chunk of china
12:55 PM roycroft: i've never filtered a network that large before, but the hits are coming from all over the place
12:56 PM MrSunshine: btw, does hostmot totaly take over the nic when running against a mesa card ?
12:56 PM MrSunshine: internet connectivity and everything dies on the computer :P
12:57 PM roycroft: mesa cards should be on a separate ethernet port and network than the internet connction on the host computer
12:58 PM roycroft: i'm not sure if you can share a single physical interface by using vlans, but even if that worked, it's a bad idea
01:00 PM MrSunshine: roycroft, yeah i figured i should add a nic just for mesa leter but atm its kinda annoying when im trying do get the machine working that i have to close linuxcnc to get the internet connectivity back :P
01:01 PM roycroft: it's designed that way
01:02 PM roycroft: i put a wifi adapter in my linuxcnc machine for local network access, so i could use the built-in ethernet adapter for the mesa card
01:02 PM roycroft: i don't connect that machine to the public internet though - that is just too scary a concept for me to deal with
01:03 PM roycroft: i configured it to be part of my local network, so that other machines can talk to it, but it has a dummy gateway address, so it cannot reach the outside world
01:03 PM roycroft: and i block its ip address on my firewall as a belt-and-suspenders measure
01:04 PM roycroft: that ukraine network is also hammering my personal mail server, which is in another part of the world from the work servers
01:04 PM * roycroft wonders if it's something the russians have taken over
01:05 PM roycroft: or perhaps russian sympathizers in eastern ukraine
01:06 PM MrSunshine: btw, done latency tests on the computer .. do i then need to update the servo period ? =)
01:10 PM MrSunshine: need to connect up the driver alarm circuit to the board so i can do some stress test of axis movements, as ive got the double Y gantry .. if one motor halts and the other one continues it will not be a happy day :P
01:13 PM roycroft: i'm going to configure my router similarly
01:13 PM roycroft: with two joints on the y axis
01:13 PM MrSunshine: works great but today with new config i forgot one motor was set at 640 in scale and the other 320 ... so when homing one motor moved to slow :P
01:14 PM MrSunshine: or fast or wahtever ...
01:20 PM roycroft: i've been told to use an encoder on each joint, and i've been told it's not necessary
01:20 PM roycroft: i'll be using stepper motors, btw
01:21 PM MrSunshine: i use closed loop steppers =)
01:21 PM MrSunshine: best thing ever when you cant afford servos =)
01:21 PM roycroft: i think that as long as i don't lose steps, and i home both joints at the beginning of every job, they should stay in sync
01:36 PM JT-Cave: MrSunshine, I put another nic in the pc like a usb or pcie nic
02:09 PM MrSunshine: yeah, but do no thave any spare pcie nics .. hell i do not even have any pcie nics at all :P
02:26 PM roycroft: there is this place called ebay
02:26 PM roycroft: it has heaps of cheap hardware like that
02:26 PM roycroft: it will let you just click on a button and the cheap hardware will magically arrive at your doorstep within days
02:45 PM MrSunshine: i usaly take a trip to the dump to check the electronics if i need old electronics =)
02:45 PM MrSunshine: got alot of good computers etc, as long as i leave the harddrive they let me take it =)
02:56 PM XXCoder: I like his bending tool https://youtu.be/xaLWKxxuKqQ

03:27 PM andypugh: XXCoder: Did you notice his hollow-ground “gunsmith” screwdrivers?
03:27 PM andypugh: Oh, and XXCoder it took me ages to timestamp the captions on the latest yewchube video, so you better watch it :-)
03:29 PM XXCoder: lol ok
03:29 PM XXCoder: andy at what time? (gunsmith screwdrivers)
03:36 PM andypugh: 1:17
03:37 PM XXCoder: looked like standard to me
03:37 PM XXCoder: it has #1 on it
03:39 PM XXCoder: probing mold eh
03:39 PM XXCoder: *moulding
03:42 PM XXCoder: great video so far lol
03:42 PM XXCoder: easy enough to fit circles
03:43 PM XXCoder: freecad have similiar stuff. can trim lines keaving nice shape
03:44 PM XXCoder: andypugh: ball profile offset?
03:44 PM XXCoder: oh! probe ball!
03:44 PM andypugh: Indeed.
03:46 PM XXCoder: points is more pointy lets see what you do about it lol
03:46 PM XXCoder: ah nice
03:47 PM XXCoder: while you use different program, I can see what and how to do in freecad
03:49 PM XXCoder: dont that one have vertical and horzional constrant?
03:52 PM andypugh: It does, yes. It’s a combined button that chooses the closest.
03:53 PM XXCoder: ahh ok
03:53 PM XXCoder: ui is different
03:53 PM roycroft: nickel plating is on my short list of things to learn and set up for
03:54 PM XXCoder: roy thats such good idea because it prvents so much corrosion
03:54 PM roycroft: the process is straightforward
03:54 PM XXCoder: should be.
03:54 PM roycroft: it's the disposal of the reagents that i have to get sorted yet
03:54 PM roycroft: i don't want chez roy to become a superfund site
03:55 PM CloudEvil: It would be nice if vacuum metalisation was a bit easier and diddn't have certain issues.
03:55 PM CloudEvil: No chemicals.
03:55 PM XXCoder: honestly all you need is steady containers and proper space for it
03:55 PM XXCoder: I have seen some videos of process thats very slapdash
03:56 PM XXCoder: one error and its nicely spilled all over floor and damaging
03:56 PM roycroft: i'm not concerned about spilling it
03:56 PM roycroft: i can handle it safely, i know
03:56 PM roycroft: it's disposing of the spent reagents that i don't know about
03:56 PM roycroft: i can't pour it down the drain
03:56 PM XXCoder: certainly not!
03:57 PM roycroft: i'm assuming there's a way i can neutralize it
03:57 PM roycroft: perhaps turn it into a non-toxic salt that i can dry and dispose of
03:57 PM XXCoder: should be able to depost at chemical repo at trash and recycle center
03:57 PM XXCoder: yeah after quick nuteralize then turn it in
03:58 PM roycroft: i don't think it's a hard problem to solve
03:58 PM roycroft: i've just not spent the time getting it sorted yet
03:58 PM XXCoder: shouldnt be yeah
03:58 PM XXCoder: andypugh: manual drilling into cylinder?
03:58 PM XXCoder: or is it cnc
03:59 PM XXCoder: oh I see how it works now
03:59 PM XXCoder: cutting plate. interesting
04:00 PM roycroft: i have some hand planes to refurbish
04:00 PM roycroft: and that will involve rejapanning and nickel plating
04:01 PM roycroft: i'm working on the japanning bit
04:01 PM XXCoder: nice
04:01 PM roycroft: once i get that working well i'll do the nickel plating bit
04:01 PM XXCoder: I think japanning is bit cool. predates very hard powercoating
04:02 PM XXCoder: andypugh: horzional milling is what that machine is called? forgot name
04:02 PM XXCoder: last I saw was 7 years ago or so, at job before my last one
04:03 PM roycroft: it is cool
04:03 PM roycroft: it looks cool and it works well
04:03 PM roycroft: i just haven't figured out how to make the stuff yet
04:03 PM roycroft: i think what i need is a heated stir plate
04:03 PM XXCoder: that clamp locations makes me bit nervious lol. I know its out of way but.. lol
04:04 PM roycroft: every attempt to make it so far has ended up with a lump of asphaltum/resin in the bottom and the turpentine floating on the top
04:04 PM roycroft: i haven't found a way to dissolve the asphaltum and resin
04:04 PM XXCoder: andypugh: its quite reusable, you can make so many different plates for different moulding,
04:05 PM XXCoder: roy plenty of cheap heated stir plates out there
04:05 PM XXCoder: its VERY typical lab device
04:05 PM roycroft: now that i have a pid controller on my heat treating/enamelling kiln i can use that for the japanning
04:05 PM roycroft: since i can dial the heat way down and hold it very accurately
04:05 PM roycroft: yeah
04:05 PM roycroft: i have a bunch of unheated stir plates that i use for brewing
04:06 PM XXCoder: cool
04:06 PM roycroft: i think i need some heat though
04:07 PM roycroft: although i have not tried mixing any japanning on a stir plate so far - i just stir it in and keep stirring a few times/day until the big lump forms
04:07 PM roycroft: then i have to toss it
04:08 PM XXCoder: dont sound like right process heh
04:08 PM CaptHindsight[m]: which polymers are used for contemporary Japanning?
04:08 PM roycroft: i don't know
04:08 PM roycroft: but the old recipe uses asphaltum and copal resin
04:09 PM roycroft: i use gilsonite for the asphaltum
04:09 PM roycroft: it's mined in the west - nevada i think
04:09 PM CaptHindsight[m]: why don't they use a 2 part urethane?
04:09 PM CaptHindsight[m]: like auto body clear
04:10 PM roycroft: because that would be paint
04:10 PM roycroft: not japanning
04:10 PM roycroft: and it did not exist in the 19th century
04:10 PM XXCoder: yep japanning is quite old
04:10 PM roycroft: i'm restoring some hand planes that are over 100 years old
04:11 PM CaptHindsight[m]: sure, but it's 2020
04:11 PM roycroft: it seems appropriate to use the techniques and materials that were available at the time
04:11 PM CaptHindsight[m]: maybe even 2022
04:11 PM roycroft: yeah, but paint does not look like japanning
04:11 PM roycroft: and it does not feel like japanning
04:12 PM CaptHindsight[m]: a 2k (2-part) clear maybe sanded and polished
04:12 PM * JT-Shop painted his #5
04:12 PM roycroft: spray paint and chrome plating slightly resembles japanning and nickel plating, but only from a distance
04:12 PM CaptHindsight[m]: but I get that some may want that old world technique since it's old
04:13 PM roycroft: japanning is not super smooth and shiny
04:13 PM roycroft: it's not meant to be that
04:13 PM roycroft: i'm not suggesting that we abandon modern processes/materials at all
04:14 PM roycroft: i'm just saying that they are not the same as some of the older ways, and that it's fine to use old methods and modern methods both, where appropriate/desirable
04:15 PM roycroft: i use modern finishes a lot
04:15 PM roycroft: but not where i want the old-time look, and the modern finish does not produce that look
04:15 PM roycroft: gilsonite does not come from nevada, btw
04:15 PM roycroft: it is mined in utah and colorado
04:16 PM XXCoder: restoring is quite different than just fixing it for more use
04:16 PM XXCoder: you want orginial processes when it makes sense
04:16 PM XXCoder: like japanning
04:17 PM XXCoder: I dont really like restore channels that just use very different process that makes old item into mirror finish show peice
04:18 PM CaptHindsight[m]: you fix that by letting some kids work with it for 15 minutes
04:19 PM satiowadahc[m]: Out of curiosity does anyone ever use the old wiki pages?
04:19 PM JT-Shop: no way to tell
04:19 PM XXCoder: traffic and page view times analsys?
04:20 PM JT-Shop: I think only wpadnos has access to that
04:23 PM XXCoder: hmm too bad
04:24 PM CaptHindsight[m]: satiowadahc: old vs new wiki or just use the wiki? Wiki, yes, Old vs new, I don't know
04:25 PM JT-Shop: I didn't know we had an old and a new wiki
04:27 PM CaptHindsight[m]: the wiki gets frequent updates
04:29 PM JT-Shop: it's user maintained
04:30 PM * JT-Shop needs to stop looking at Lie-Nielsen stuff
04:30 PM JT-Shop: I keep getting a call from area code 206 but they don't leave a message
04:33 PM Tom_L: spies
04:33 PM roycroft: it's jeff bezos wondering why you're not sending him money for his penis rocket
04:34 PM JT-Shop: lol
04:35 PM roycroft: i don't even know the boundaries of areacode 206 any more
04:35 PM roycroft: when i moved to bellingham, right up by the canadian border, it was in 206
04:35 PM JT-Shop: somewhere out your way
04:35 PM roycroft: then it moved to 360, and the greatre seattle area was 206
04:35 PM roycroft: but there are even more areacodes in western washington now
04:35 PM JT-Shop: it ain't from roundere
04:36 PM roycroft: soon 206 will just be the starbucks on every street corner in downtown seattle
04:36 PM JT-Shop: lol
04:37 PM CaptHindsight[m]: "we are calling about your cars warranty..."
04:38 PM XXCoder: you forgot extended, CaptHindsight[m]
04:38 PM Tom_L: yeah they call me about my rav4's warranty and i've never owned one
04:38 PM JT-Shop: lol
04:39 PM * JT-Shop never answers an unknown number... well almost never
04:39 PM CaptHindsight[m]: “I’m calling today with important news about your car’s extended warranty.” i think that is the script
04:39 PM XXCoder: if I could talk to them, id randomly choose extremely expensive car and ask if they mean that one
04:39 PM Tom_L: my phone comes up with 'spam' or 'telemarketer' now
04:39 PM XXCoder: also randomly extremely rare or very crap cars lol
04:39 PM JT-Shop: how long have you known the deceased?
04:39 PM CaptHindsight[m]: I'm finding it tougher to keep them on the line
04:40 PM Tom_L: CaptHindsight[m], i only get to the "I'm calling toda..." and hang up
04:40 PM JT-Shop: wtf happened to no sales calls laws
04:41 PM CaptHindsight[m]: "oh you sound interesting, tell me more about yourself before we talk about cars"
04:41 PM Tom_L: she led on on for 20 min or so and they about shit... they didn't know what to do
04:42 PM CaptHindsight[m]: they use voice over ip from outside the US and just make up numbers for what you see
04:42 PM Tom_L: yeah i've had the caller id come up fake
04:42 PM Tom_L: several times
04:44 PM JT-Shop: I'm like Joe Walsh Just leave a message, maybe I'll call...
04:44 PM JT-Shop: from Life's been Good
04:45 PM roguish[m]: JT-Shop: dude, that's old......
04:45 PM JT-Shop: https://en.wikipedia.org/wiki/Life%27s_Been_Good
04:45 PM JT-Shop: dude I'm old
04:46 PM roguish[m]: yeah, man. not far behind ya.
04:46 PM CaptHindsight[m]: I think that only works on dial phones :)
04:46 PM CaptHindsight[m]: rotary
04:46 PM roguish[m]: drop a dime
04:47 PM JT-Shop: so I'm making an egg box with a top similar to this https://gnipsel.com/images/wood-working/table-top/table-top-01.jpg
04:47 PM CaptHindsight[m]: there was a video asking people under 30 if they knew how to operate a rotary phone
04:47 PM CaptHindsight[m]: many did not
04:47 PM JT-Shop: but want to make a floating edge that sticks up 1/2" or so
04:47 PM JT-Shop: roycroft, any ideas?
04:48 PM JT-Shop: most people under 50 can't count or give change... when I worked at Burger King there was no register... you did in your head
04:49 PM roycroft: i was taught to count the change back to the customer up to the mount tendered
04:49 PM Tom_L: yeah they give you a dumb look when you correct them
04:49 PM roycroft: not just hand them a wad of money
04:49 PM XXCoder: wow
04:49 PM XXCoder: hot air device is awesome. I very quickly removed strings from prints
04:49 PM Tom_L: god forbid you give them exact change
04:49 PM roycroft: so if their bill was $16.48, and they handed me a $20 bill, i'd pull their change out of the till and count it back to them
04:49 PM XXCoder: and melted prototype part easuly. and when its cooled, it is stronger than before
04:50 PM roycroft: "$16.48, $16.49, $16.50, $16.75, ..." until i got to $20
04:50 PM JT-Shop: starting with the change up to $20
04:50 PM roycroft: nobody can do that these days without a calculator or computer
04:50 PM Tom_L: we're not all dead yetQ
04:50 PM Tom_L: !
04:51 PM JT-Shop: well you can't say nobody because we are not dead yet
04:51 PM roycroft: that was also how i would pull the change out of the till
04:51 PM CaptHindsight[m]: $16.48 for the total and you hand them a $20 and 48 cents, they freeze
04:51 PM Tom_L: the world will certainly go to shit when we do
04:51 PM roycroft: because the cash register did not tell me how much money to give them back
04:51 PM CaptHindsight[m]: yes you just give me back 4 singles
04:51 PM roycroft: yes, they do
04:51 PM JT-Shop: a lot of merchants here count back the change
04:51 PM roycroft: or the bill is $20.40, and you hand them $26
04:51 PM roycroft: they freak out
04:51 PM roycroft: hand you the $1 bill back
04:51 PM roycroft: and then make change for $25
04:52 PM roycroft: that's a bad example, because they would give you the $5 back
04:52 PM CaptHindsight[m]: the $5 part of the drawer is just an IN BOX
04:53 PM roycroft: bu the principle is the same
04:53 PM JT-Shop: I like to hand them the change and say here's a down payment, I'll gladly pay you Tuesday for a hamburger today
04:53 PM roycroft: also, when a credit card won't run they freak out and demand cash
04:53 PM roguish[m]: hey Wimpy
04:53 PM JT-Shop: lol
04:53 PM CaptHindsight[m]: I usually mess with them when getting cash back at a register. How would you like the $60 sir?
04:53 PM roycroft: i tell them to call for a manual authorization, and they look at me like i'm speaking ancient sumarian
04:53 PM CaptHindsight[m]: oh 2 30's
04:53 PM JT-Shop: I knew someone would get it
04:54 PM CaptHindsight[m]: 4 15's
04:54 PM roguish[m]: told ya, not too far behind................ and always loved cartoons.
04:54 PM roycroft: this doesn't work any more, but about 15 years ago i was at jerry's, a local home improvement store, and the cc terminals were down
04:54 PM JT-Shop: rotflmao
04:55 PM roycroft: i was trying to buy several hundred dollars worth of lumber, and did not have that much cash on me
04:55 PM roguish[m]: it
04:55 PM roycroft: i told the cashier "look in the drawer below the cash register - you'll find a credit card imprinter, and a stack of cc receipts"
04:56 PM roycroft: and they thought i was crazy
04:56 PM roycroft: but eventually looked in the drawer, found the stuff, and had no ide what to do with it
04:56 PM CaptHindsight[m]: work of the devil
04:56 PM Tom_L: i remember when that's all there was for cc
04:56 PM roguish[m]: it's probably pretty easy to do the old short change trick now. especially on the yutes.
04:56 PM roycroft: i had to walk them through the process, including helping them find the phone number for the manual authorization
04:56 PM JT-Shop: none of my cards have embossed numbers
04:57 PM roycroft: no, that's why i said that doesn't work any more
04:57 PM roycroft: the imprinters are gone
04:57 PM roycroft: but even the modern cards cashiers have problems with
04:57 PM XXCoder: training takes money and time. they dont bother for while now
04:57 PM roycroft: i was at home depot recently, and the customer ahead of me insterted a card whose chip could not be read
04:58 PM roycroft: the cashier had no idea what to do, and asked if they had cash
04:58 PM roycroft: they didn't
04:58 PM CaptHindsight[m]: half the stores I go to have self serve checkouts that have a negative sounding beep when approved, like when you give the wrong answer on a game show
04:58 PM roycroft: i had to walk them through inserting it and getting it rejected three times, until the cc terminal instructed them to swipe
04:58 PM roycroft: which they finally did, and it worked
04:58 PM XXCoder: local mcdonalds is so automated at drive though that guy who is new dont know how to handle cashier orders, since I give them paper with orders
04:58 PM roycroft: and the cashier was completely dumbfounded
04:59 PM XXCoder: one cashier was upset. if that guy tried to ban me from driveway that'd be violation of laws
04:59 PM XXCoder: *drivethough
04:59 PM roycroft: oh, yes, they don't want an ada lawsuit :)
04:59 PM XXCoder: yep. i hate drivethough, but with fun years I have no choice
05:03 PM JT-Shop: because of dizziness?
05:03 PM XXCoder: covid
05:04 PM JT-Shop: ah
05:04 PM XXCoder: I try to cut exposes becaue my lungs is damaged, and my mom whos over 70 lives with me
05:05 PM XXCoder: but it was over year that mcdonald didnt let people dine inside
05:05 PM JT-Shop: my wife is 70
05:05 PM XXCoder: is your wife my mom? ;) kidding lol
05:05 PM XXCoder: ... dad?
05:07 PM JT-Shop: she's Puerto Rican
05:07 PM XXCoder: cool :D
05:07 PM roycroft: i'm not sure what you mean about that lid, jt-shop
05:07 PM JT-Shop: I'm Alaskan sorta
05:07 PM roycroft: do you just want a raised lip around the edge?
05:07 PM Tom_L: where did you meet?
05:07 PM XXCoder: my moms dad come over from sweden iunto usa when he was young
05:08 PM JT-Shop: I want to make like a raised lip and allow the top to float like a cabinet door
05:08 PM XXCoder: joined ww2, all I know is he went to germany and japan and returned after 2 nukes
05:08 PM XXCoder: he refused to say anything else
05:08 PM JT-Shop: Tom_L, Harahan Louisana
05:08 PM roycroft: oh, so just make it like a door
05:08 PM roycroft: stile and rail, and shape them so that they have a bead sticking up on the edge
05:08 PM CaptHindsight[m]: my parents would into the triple digits if they were still around
05:09 PM JT-Shop: pretty much what I'm thinking but don't want a raised edge on top
05:09 PM roycroft: if you make it shaker style the panel will be flush with the frame
05:09 PM JT-Shop: ok I'll look
05:09 PM roycroft: the panel will just be rebated around all four edges
05:10 PM JT-Shop: would that work with a 1" wide edge as viewed from the top
05:14 PM roycroft: it could
05:14 PM roycroft: just make the rebates/grooves 3/8" wide
05:15 PM CaptHindsight[m]: XXCoder: my parents didn't discuss WWII much either except when they compared everything to what Stalin or Hitler would have done :)
05:15 PM JT-Shop: ok, I'll draw that up and see how it looks
05:15 PM CaptHindsight[m]: lots of things in the news would be shot or hung :)
05:17 PM Guest99: I tried to order WCH CH382L. http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH
05:17 PM Guest99: When I do lspci I get:
05:17 PM CaptHindsight[m]: Guest99: no luck?
05:18 PM * JT-Shop listens to Ricky Lee Jones Last Chance Texaco
05:18 PM Guest99: 01:00.0 Serial controller: Device 1c00:3050 (rev 10)
05:20 PM Guest99: `lspci -v | grep par` outputs:
05:20 PM JT-Shop: A version of this card with the CH382L chipset exists, which does not function as a PARALLEL PORT. It is sold as one, looks like one. However, does not show up in Linux as a parallel device. The card functions as a serial translated parallel output.
05:20 PM Guest99: Kernel driver in use: parport_pc
05:20 PM Guest99: Kernel modules: parport_pc, parport_serial
05:21 PM Guest99: How can I find out if this one will work with Linuxcnc?
05:22 PM CaptHindsight[m]: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH
05:22 PM JT-Shop: <Guest99> I tried to order WCH CH382L. http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH
05:22 PM CaptHindsight[m]: This driver was added to the kernel for Dev. ID 3050, Date: Sat, 26 May 2018, Kernel 4.14
05:23 PM CaptHindsight[m]: Debian also back ported this to earlier kernels since it is working with Kernel 4.9
05:24 PM Guest99: So when lspci outputs "01:00.0 Serial controller: Device 1c00:3050 (rev 10)" the 3050 is the device ID. So this one will work with Linuxcnc?
05:25 PM CaptHindsight[m]: I have that card here. I have to pop it in and reboot
05:26 PM CaptHindsight[m]: here is something to listen to while on hold https://www.youtube.com/watch?v=I6OsvbgEeYs
05:30 PM CaptHindsight[m]: just starting back up......
05:33 PM CaptHindsight[m]: ok back up
05:33 PM olbastard[m]: Hello .. New Here .. just reading in on chat to see what I can learn.. Just starting with LCNC switching from grbl
05:38 PM CaptHindsight[m]: 1c00:3050 Kernel driver in use: parport_pc
05:40 PM XXCoder: very safe https://media.discordapp.net/attachments/343070336084082708/963927509408313364/unknown.png
05:50 PM Guest99: I am getting lots of connection errors I am going to try to switch the webclient I am using.
05:52 PM Bear100: So I was having connections problems.
05:52 PM Bear100: Did someone answer this question when I was disconnected.
05:52 PM Tom_L: not yet
05:53 PM Bear100: I was asking if "01:00.0 Serial controller: Device 1c00:3050 (rev 10)" would work with Linuxcnc.
05:53 PM Tom_L: but here's how to find out
05:54 PM Tom_L: olbastard[m], what do you have? a mill etc?
05:55 PM Tom_L: linuxcnc is quite a bit more robust than grbl
05:55 PM CaptHindsight[m]: Bear100: https://forum.linuxcnc.org/38-general-linuxcnc-questions/41199-can-i-use-a-wch-parallel-port-card
05:55 PM Bear100: Tom_L thanks it is a good suggestion to check the logs.
05:55 PM Tom_L: index also works
05:55 PM olbastard[m]: Mill .. wanting to try it with a 4th axis
05:56 PM Tom_L: rotary?
05:56 PM olbastard[m]: yup
05:56 PM Tom_L: i just set up a rotary on mine
05:56 PM olbastard[m]: will def be a new learning experiance
05:57 PM Tom_L: https://www.youtube.com/watch?v=pvDBfJQT2Ec
05:57 PM Tom_L: skip the first 2/3 of that
05:57 PM olbastard[m]: LCNC has soo much more from all ive been reading
05:57 PM Tom_L: i didn't have the post fixed so it's real slow on the first cut
05:58 PM roguish[m]: olbastard[m]: most important thing you should do is RTFM. then ask questions here....
05:59 PM Tom_L: oh hell no.. ask first then read after getting yer arse chewed for not reading!
06:00 PM Tom_L: roguish[m], sometimes it's hard for a noob to know what to look for and the information is kinda spread out all over
06:01 PM Tom_L: but yeah, at least have an idea what you're talking about...
06:01 PM CaptHindsight[m]: Bear100: what we don't know is if all the WCH382L cards all use the same chip. The Chinese often will relabel a device with something that works that is similar.
06:01 PM JT-Cave: lol
06:01 PM CaptHindsight[m]: my WCD382L cards work with LCNC
06:02 PM Tom_L: wow.. this video has cred.. they show a pic o the Machinery's Handbook right off the bat
06:02 PM CaptHindsight[m]: another WCH382L card might use a microcontroller that has been programmed to respond in a similar way and have the same PCI device id's
06:02 PM CaptHindsight[m]: but in use may behave differently
06:03 PM Tom_L: oh, no wonder... it's an Old Tony yt
06:03 PM Bear100: CaptHindsight[m] okay
06:03 PM CaptHindsight[m]: s/WCD382L/WCH382L/
06:03 PM olbastard[m]: Ya .. Im NOT new to linux so i know all about the RTFM ... lol
06:03 PM Bear100: CaptHindsight[m] I am going to try to setup stepconf and see if I can jog the axes.
06:04 PM CaptHindsight[m]: Bear100: that is a good first step, be aware if the Step signals are active high or low
06:04 PM CaptHindsight[m]: Bear100: I don't know which polarity your LPT "controller" card expects Step and Dir to be
06:05 PM Tom_L: omg, he must be an ole phart too.. his Machinery's Handbook is the same edition i have
06:05 PM Bear100: CaptHindsight[m] what section of the documentation covers "step signals are active high or low"?
06:06 PM CaptHindsight[m]: Dir is usually easy since it stays either High or Low for the whole time the axis remains in the same travel direction, and you can flip polarity to match your desired direction of travel
06:06 PM CaptHindsight[m]: Bear100: no docs cover it
06:07 PM CaptHindsight[m]: if Step is inverted you will just miss a step every time it runs
06:08 PM CaptHindsight[m]: or gain an extra step
06:08 PM olbastard[m]: Imm gonna have a biatch of a time CAM wise i guess with a rotary
06:09 PM Tom_L: i was kinda surprised my old cam supported it
06:09 PM Bear100: So to flip the p[olarity you would use the invert checkboxes in stepconf?
06:09 PM Bear100: http://linuxcnc.org/docs/stable/html/config/stepconf.html#_parallel_port_setup
06:11 PM CaptHindsight[m]: Bear100: http://linuxcnc.org/docs/stable/html/motion/tweaking-steppers.html
06:11 PM CaptHindsight[m]: Bear100: http://linuxcnc.org/docs/stable/html/config/stepper.html#_changing_polarity_of_a_signal
06:13 PM Bear100: CaptHindsight[m] oh manual editing configuaration files.
06:14 PM CaptHindsight[m]: yes
06:14 PM Tom_L: olbastard[m], you could try fusion360
06:15 PM CaptHindsight[m]: Bear100: but you can do that later, just run the tests first and see if they jog and change direction
06:15 PM olbastard[m]: Tom_L: my internet out here in the sticks is soo slow cant really get it to work woth a crap
06:15 PM CaptHindsight[m]: Bear100: you have wiring to sort out first
06:15 PM Tom_L: well, nobody can really but it was a suggestion :)
06:16 PM Tom_L: good cam is a bottleneck for linuxcnc
06:16 PM Bear100: CaptHindsight[m] do you mean the pinout for the parallel port break out board?
06:17 PM CaptHindsight[m]: Bear100: yes, pinout and power connections
06:17 PM CaptHindsight[m]: and ground
06:17 PM Bear100: Tom_L how about OpenSCAD or FreeCad for CAD and FreeCad for CAM?
06:17 PM Tom_L: it's getting better but has a long ways to go
06:17 PM olbastard[m]: freecad doesnt do rotary
06:18 PM Tom_L: and i dunno if it does rotary
06:18 PM Tom_L: openscad... gimme a break :)
06:18 PM olbastard[m]: I see they are doing experimantal plugin with lathe though
06:19 PM CaptHindsight[m]: FreeCAD/Path is still in development, hard enough to just have 3-axis work well
06:20 PM Tom_L: mine does wrapped geometry which i think most of them do unless you get into the $$$ 5+ axis
06:20 PM CaptHindsight[m]: Fusion360 is the lowest cost 4-axis CAM currently
06:20 PM CaptHindsight[m]: that actually works
06:20 PM Bear100: CaptHindsight[m] my parallel port break out board looks like the one in https://forum.linuxcnc.org/49-basic-configuration/35628-basic-configuration-for-a-chinese-6040-cnc-router-please?start=10
06:20 PM olbastard[m]: ya G-Code Ripper .. but not really the same lol
06:20 PM Bear100: So I am going to try that pinout.
06:21 PM CaptHindsight[m]: https://www.scorchworks.com/Gcoderipper/gcoderipper.html
06:21 PM CaptHindsight[m]: Bear100: https://forum.linuxcnc.org/media/kunena/attachments/21555/jp3163b-6040cnc-002.jpeg
06:22 PM Bear100: CaptHindsight[m] yeah that is the one I am going to try.
06:22 PM Tom_L: olbastard[m], what's your cnc background out of curiosity?
06:23 PM Bear100: I do not think I have an A axis so I can leave those pins unused?
06:23 PM Tom_L: yes
06:23 PM olbastard[m]: noob really.. had a home built one for just over a year.. mostly 2d
06:24 PM CaptHindsight[m]: Bear100: yes
06:24 PM Tom_L: well you seem less 'noob' than most noobs that join here :)
06:24 PM CaptHindsight[m]: Bear100: I saw only XYZ on your machine
06:24 PM Tom_L: olbastard[m], a gantry?
06:25 PM olbastard[m]: its been on a usb /arduino running bCNC .. and changed it over to parallel and been tinkering for a cpl weeks now
06:26 PM Tom_L: parallel will work with lcnc but the stepgens are slower than offloading to hardware
06:26 PM olbastard[m]: ya.. y900 x500 z300 .. but z i raised the deck to only about 100mm
06:28 PM Tom_L: mesa makes some nice cards for lcnc to make life easier
06:28 PM CaptHindsight[m]: Bear100: Serial controller: Device 1c00:3050 (rev 10) (prog-if 05 [16850])
06:28 PM CaptHindsight[m]: I/O ports at dc00 [size=256]
06:28 PM CaptHindsight[m]: I/O ports at df00 [size=4]
06:28 PM CaptHindsight[m]: I forget which port address works
06:28 PM olbastard[m]: right now im tinkering on getting a touchprobe to work .. so many options
06:28 PM Tom_L: parallel, ethernet, pci, pcie
06:29 PM Tom_L: lcnc has touch Gcode
06:29 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cradek/
06:29 PM Bear100: For <https://forum.linuxcnc.org/media/kunena/attachments/21555/jp3163b-6040cnc-002.jpeg> I am not sure what to put for in pin 14 x,y,z,a axis enables
06:29 PM Tom_L: some samples of touchoff
06:30 PM Bear100: or for in pin 15 tool seeting
06:31 PM Tom_L: 15 unused
06:31 PM Bear100: CaptHindsight[m] me lspci says:
06:31 PM Bear100: I/O ports at e000 [size=256]
06:31 PM Tom_L: unless you have a touch pad for your tool settings
06:31 PM Bear100: I/O ports at e100 [size=4]
06:31 PM Tom_L: 14 would be your axis enable pins
06:31 PM Bear100: Tom_L I do not have a touch pad.
06:31 PM Tom_L: ignore it then
06:32 PM CaptHindsight[m]: Bear100: you will have to try both
06:32 PM Bear100: Tom_L I am not sure what that would map to in terms of the drop down list.
06:32 PM CaptHindsight[m]: and see
06:32 PM Bear100: CaptHindsight[m] okay I will try both.
06:33 PM olbastard[m]: and i put all axis limit/home on 1 pi... I think that works in my situation and saves me a few pins
06:34 PM Bear100: I do not have limit switch so i would leave those disabled.
06:34 PM Tom_L: olbastard[m], it can be done but you won't know which axis faulted
06:35 PM Tom_L: homing the axis might be an issue
06:36 PM olbastard[m]: Ya i came across a cple times one switch was engauged and when trying to home it went in the wrong direction
06:36 PM Tom_L: you could possibly set each axis to home separately and get that to work
06:36 PM XXCoder: lol apparently honda went manic and reported ALL models with honda name on it to be removed
06:37 PM olbastard[m]: so just set them all to 2mm off of limit /home switch
06:37 PM XXCoder: stupid move
06:37 PM Tom_L: HOME_SEQUENCE = 1
06:38 PM Tom_L: so you could do HOME_SEQUENCE = 0 for one 1, 2 for the others
06:38 PM Tom_L: 0 would home first
06:38 PM Tom_L: then the rest in order
06:38 PM olbastard[m]: is there a way to get a home all button if i have the a axis not set to specific home?
06:38 PM Tom_L: i've never tried it that way
06:38 PM Tom_L: you can set "HERE" as a home point yes
06:39 PM olbastard[m]: Ya.. thats how its set up.. z first then x then y
06:39 PM Bear100: Not sure what to do with pin 14 the only thing with enable in the drop down is "Amplifier Enable" but that does not seem to match <https://forum.linuxcnc.org/media/kunena/attachments/21555/jp3163b-6040cnc-002.jpeg> pin information very well.
06:40 PM olbastard[m]: A will home wherever its at when i hit the home button.. but wou;ld like a home all button and not have to do seperatly
06:40 PM Bear100: x,y,z,a axis enabled
06:40 PM CaptHindsight[m]: Bear100: ignore for now
06:40 PM olbastard[m]: Bear100 ya.. thats the one
06:40 PM Bear100: CaptHindsight[m] so set pin 14 to unused?
06:40 PM Tom_L: MDI_COMMAND = G10 L20 P1 X0
06:41 PM olbastard[m]: amplifier enable was the only way i could gewt mine to work
06:41 PM Tom_L: G10 will set the axis where it sits
06:41 PM Tom_L: G10 L20
06:41 PM Tom_L: http://linuxcnc.org/docs/stable/html/gcode/g-code.html#gcode:g10-l2
06:42 PM Tom_L: i'm not sure if that sets world coordinates though
06:43 PM Tom_L: there may be another way for that
06:43 PM olbastard[m]: lol.. been rading all the G/M codes whikle looking through a bunch of sub commands to see what they are for/doing
06:44 PM Tom_L: my limits are on separate io so i've never had to deal with that
06:44 PM olbastard[m]: you have a limit switch on rotary? or encoder?
06:44 PM Tom_L: no
06:45 PM Tom_L: i set it where it sits
06:45 PM Tom_L: MDI_COMMAND = G10 L20 P1 A0
06:45 PM olbastard[m]: and AXIS interface goves you a home all button?
06:46 PM Tom_L: the AXIS GUI has a home all button yes
06:46 PM Bear100: I set pin 14 to unused.
06:46 PM Tom_L: it honors the HOME_SEQUENCE =
06:47 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Current_Linuxcnc_Axis_screen.png
06:47 PM olbastard[m]: well !@#$%^& when i added the A axis it switched to having to home each seperate
06:47 PM Tom_L: that's how my A axis config looks
06:47 PM Tom_L: actually that's not the right pic
06:47 PM Bear100: Are the defaults for <http://linuxcnc.org/docs/stable/html/config/stepconf.html#_axis_configuration> okay for a axis jog test?
06:48 PM Bear100: I just tried to jog the X axis and it did not move.
06:48 PM Tom_L: enable your axis
06:48 PM Tom_L: gnd the enable pins on the drivers
06:49 PM * olbastard[m] uploaded an image: (105KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/FfGATIzufVJzukXOskghyKSp/image.png >
06:50 PM Tom_L: you can add widgets to the right pannel
06:50 PM Tom_L: well, maybe you did with the probe
06:50 PM olbastard[m]: ya been looking at those
06:50 PM Tom_L: can't seem to find my A axis gui pic
06:51 PM olbastard[m]: Probe is just led.. was my firt one a cple days ago
06:51 PM * olbastard[m] uploaded an image: (71KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/IKWJmKOmaiFIhphEkaCnbDmR/image.png >
06:52 PM olbastard[m]: Bear .. thats how I got mine
06:53 PM olbastard[m]: But like i said.. just started with mine.. my trial A axis rotates
06:54 PM olbastard[m]: right now im using a stepper with wood gears I cut giving it a 5:1 to test with before I $$ for a real one ... lol
06:54 PM Tom_L: when you start adding things like a pendant you will need more IO
06:55 PM olbastard[m]: Are you able to use a 2nd parallel port for more.. or do ya really need a mesa card
06:56 PM Tom_L: i think you can yes
06:56 PM Tom_L: mesa is sooo much nicer though
06:56 PM Tom_L: faster step rates, more io etc
06:57 PM olbastard[m]: ya.. and more $$ .. Im a cheap olbastard
06:57 PM Tom_L: well, me too but i didn't cheap on my control
06:58 PM Tom_L: got good drivers and mesa cards, most of the rest was pulled from a scrap yard
06:58 PM CaptHindsight[m]: Bear100: in your .hal file the LPT port for yours will be "0xe100"
06:58 PM CaptHindsight[m]: the [size=4] port
07:01 PM Bear100: CaptHindsight[m] I just tried both of them 0xe000 and 0xe100 and for both the X axis did not jog.
07:02 PM Bear100: Also pin 14 unused or amplifier enabled does not get the x axis to jog.
07:04 PM Bear100: CaptHindsight[m] I set the address using the paraport base address in <http://linuxcnc.org/docs/stable/html/config/stepconf.html#_parallel_port_setup>.
07:10 PM olbastard[m]: <Tom_L> "i think you can yes" <- Well im not too worried about speeds.. mine is for hobby no production
07:12 PM Bear100: Thanks everyone for the help. The work shop is closing so I will try again later.
07:13 PM CaptHindsight[m]: Bear100: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester
07:13 PM olbastard[m]: I got just a cheap 400watt spindle i adjust the speeds with Potentiometer
07:15 PM Tom_L: i did for quite a while
07:19 PM Tom_L: i started pushing the motor more so i added 'coolant' to it: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/spindle_cooler/Cooler3.jpg
07:20 PM Tom_L: then finally updated the motor http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Motor_mounted1.jpg
07:20 PM CaptHindsight[m]: https://i.imgur.com/Vo7s0Et.jpg 350W motor on the right, 400W Chinese motor on the left
07:21 PM Tom_L: the first one was a sherline motor
07:21 PM Tom_L: :)
07:21 PM olbastard[m]: ive also been trying to figure out how to scan the maximum boundries of an ngc for placements of stock.. read a few that require alof of work to get it going.. ive seen in AXIS how you can check the properies and it shows them but cant figure out how to grab them
07:21 PM Tom_L: CaptHindsight[m], tie the shafts together and see who wins
07:26 PM olbastard[m]: I got a few 1-4hp well pump motors that look like giant spindles.. wonder if i could rig one up just to see what they would do
07:26 PM Tom_L: olbastard[m], i generally get that info from my cad file
07:27 PM Tom_L: https://forum.linuxcnc.org/20-g-code/35367-scan-feature-to-move-around-maximum-boundaries
07:28 PM olbastard[m]: ya.. im still kinda hooked on bCNC .. it was able to just pull it and could click scan and it would move xy max limits so i knew it wasnt going to cut inso a place i already cut out of my stock
07:30 PM olbastard[m]: Ya.. I was reading that... like i said .. im a noob and still reading up on hal and figuring out all the configs etc
07:30 PM Tom_L: mine are online if you wanna read them
07:31 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.2/
07:31 PM Tom_L: kindof a mess because i experiment with them from time to time
07:31 PM Tom_L: anything _A is a separate config for the a axis
07:32 PM Tom_L: other than that they should be identical
07:42 PM olbastard[m]: ok.. what is "DIRHOLD = 200" in the INI? I dont have those in mine.. is that
07:43 PM Tom_L: part of the stepper timing
07:44 PM olbastard[m]: I know mine hold position at 100% .. in the grbl i could change that to like 10% for when its just setting so the motors dont get hot sitting with 100% hold
07:44 PM Tom_L: http://linuxcnc.org/docs/stable/html/motion/tweaking-steppers.html#_use_steplen_stepspace_dirsetup_and_or_dirhold
07:44 PM olbastard[m]: so was reading through yours seeing if it had something like that
07:45 PM Tom_L: steppers getting hot is more a function of the driver
07:46 PM Tom_L: i use geckos which have idle current shutdown
07:48 PM Tom_L: somewhere there is a chart showing different driver step timing but i can never find it
07:50 PM Tom_L: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Drive_Timing
07:51 PM olbastard[m]: well I see this in your ini and added it to mine and now I have a home all button..... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/2b3d602204529c8e532586e7b69d4a80e8e684f6)
07:53 PM Tom_L: btw, where is your 'out in the sticks'?
07:53 PM Tom_L: where are you?
07:54 PM olbastard[m]: Northern Kalifornia 100 miles north of Sacramento
07:54 PM Tom_L: cool
07:54 PM Tom_L: mesa is out in Ca
07:54 PM Tom_L: Ks here
07:57 PM Tom_L: i home my Z first then X & Y at the same time
07:59 PM olbastard[m]: I do Z X Y A because I share the home/limit on 1 pin,, so it will do 1 at a time
07:59 PM olbastard[m]: I tried xy at same time.. it works unless they both trigger at same time then @#$%^
07:59 PM Tom_L: heh
08:00 PM Tom_L: so that all works on one pin now?
08:01 PM olbastard[m]: there is SO MUCH MORE to linuxcnc than grbl can get overwheled.. or in my case .. sidetracked because i come across dif things
08:01 PM Tom_L: yep
08:01 PM Tom_L: it's rather powerful
08:01 PM Tom_L: grbl doesn't have any canned cycles either
08:01 PM olbastard[m]: yup all work on one pin... well home switches do.. i dont use limit switches
08:01 PM Tom_L: you can sync axis too for synchronized motion
08:01 PM Tom_L: as you saw on the rotary
08:02 PM Tom_L: you can also do rigid tapping etc if your spindle is strong enough
08:02 PM Tom_L: you can set soft limits in the ini per axis too
08:02 PM olbastard[m]: hopefully ill get into that eventually
08:03 PM Tom_L: no time like the present
08:03 PM Tom_L: MIN_LIMIT = -17.750
08:03 PM Tom_L: MAX_LIMIT = 0.050
08:03 PM olbastard[m]: I mainly do 2d cuts.. but Also want to be able to rotary for my tobacco smoking pipes
08:04 PM Tom_L: lcnc will stop before it crashes if you set those
08:04 PM Tom_L: set a HOME_OFFSET and each axis will move off the switch by that amount
08:05 PM Tom_L: you may already have that
08:05 PM Tom_L: the HOME_SEARCH_VEL and HOME_LATCH_VEL set the movement speed for those
08:06 PM Tom_L: use a negative on HOME_LATCH_VEL so it backs off the switch
08:07 PM olbastard[m]: yup.. mine moves to 2mm inward from switch
08:07 PM Tom_L: so my X axis will move 17.75" and stop
08:08 PM Tom_L: i do have limits on both ends though but the far one never gets tripped
08:08 PM Tom_L: that would be ideal for yours since you only have 1 switch
08:09 PM Tom_L: just figure out how far each one can go
08:11 PM olbastard[m]: I have an embedded touchplate at front right for manual tool changing.. now i got to get use to using negative DRO as apposed to it being zero and going positive
08:12 PM Tom_L: i'm used to setting all my tools above any workpiece and adjust for that in the model
08:12 PM Tom_L: kindof a safety factor
08:12 PM Tom_L: so if you go to 0 it should clear anything
08:13 PM Tom_L: generally about 1" above
08:13 PM Tom_L: my Z retract is lower and set per tool
08:13 PM olbastard[m]: grbl was allowing me to set any corner as 0,0,0 .. but looks like the true origin has hidden
08:14 PM Tom_L: you can set work offsets in lcnc and G54 is the default one
08:14 PM olbastard[m]: so do you touchoff to the material being cut or the spoiler and zero
08:14 PM Tom_L: i use a 123 block to set all the tools but you can't do that if you have a collet system
08:14 PM Tom_L: i have individual holders
08:14 PM Tom_L: so i can preset them
08:15 PM olbastard[m]: ive done both.. and also done both in freecad.. just not sure what anyone else prefers and why
08:15 PM Tom_L: you can argue points on any of them, i just like this way
08:15 PM Tom_L: used to run big ones and that's how we did it
08:17 PM olbastard[m]: I really use both depending on how i hold the work.. if it right to the spoiler i zero the spoler.. if in vice then to the top of the stock
08:18 PM olbastard[m]: been reading up on doing direct movements for cutting.. looks like high learning curve with bit offsets etc
08:18 PM Tom_L: not sure i follow what you mean
08:19 PM olbastard[m]: but i got nothing but time.. so ill learn
08:20 PM olbastard[m]: basically manually cutting .. no cam software.. just like you would doo witgh turning the crank wheels but through like MDI
08:20 PM Tom_L: jt has written these: https://gnipsel.com/linuxcnc/gcode/index.html
08:21 PM Tom_L: oh i use my pendant for that all the time
08:22 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/pendant/pendant2.jpg
08:22 PM Tom_L: my homebrew pendant
08:23 PM olbastard[m]: kewl.. ill have to check that deb out
08:24 PM Tom_L: he's here in the mornings and in the same timezone as me
08:24 PM Tom_L: cdt
08:29 PM olbastard[m]: that pendant.. when you switch to A does it go by degree?
08:29 PM Tom_L: yes
08:30 PM Tom_L: well that or parts of one
08:30 PM Tom_L: iirc 10 clicks is 1 deg
08:30 PM Tom_L: depending on the setting
08:32 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.2/my_jog_A.hal
08:32 PM Tom_L: i had to set it separate from the rest
08:33 PM olbastard[m]: question.. is it possible to have A rotate constantly and mill say a square stock round? or does that need to be done in all cam
08:33 PM Tom_L: probably a product of the cam software
08:34 PM Tom_L: you might be able to pull it off otherwise but i haven't tried it
08:34 PM Tom_L: put it in an endless subroutine?
08:35 PM Tom_L: but that would interfere with the other axis..
08:35 PM olbastard[m]: @#$%^ was hoping to be able to cheat it as kind of a lathe and then just use like Y to run back and forth and spindle rout the shape
08:36 PM Tom_L: you could use synchronized motion which would move 2 at once in sync
08:37 PM olbastard[m]: I guess then would have to use like a rpi to make it constantly rotate .. but reading LCNC can contril so much it might still be possible
08:37 PM Tom_L: no easy button on that one that i can think of
08:38 PM Tom_L: i had a rpi hooked to mine to test it
08:38 PM Tom_L: using the ethernet interface to mesa
08:38 PM olbastard[m]: rpi4? I only got 3b+'s
08:38 PM Tom_L: rpi4 yes
08:39 PM Tom_L: the others don't do so well
08:39 PM olbastard[m]: seen one said they got LCNC wortking on a 3 .. but i wouldnt trust how slow they are
08:39 PM XXCoder: bit hard to get rpi4s for now
08:39 PM Tom_L: https://www.youtube.com/watch?v=g0OLIth_cOI
08:40 PM olbastard[m]: but i have no limit on linux machines.. thats all i run for os's anyways
08:42 PM olbastard[m]: Hard getting almost any electronics.. and the prices are skyrotteing
08:42 PM Tom_L: some do better than others on latency
08:42 PM olbastard[m]: same with the price of wood
08:44 PM olbastard[m]: well i found out the same pc dual booted with debial bullseye fully loaded had crap latency and with debian buster LCNC image alone hase alot better .. .same system
08:49 PM Tom_L: also fiddle with the bios settings
08:49 PM olbastard[m]: booting my server OS it will set about 30,000 then spike to 10x thats every few minutes.. with lcnc image it sits at 25,000 constant.. not great.. but dont want to dedicate a pc just yet
08:50 PM Tom_L: the rpi4 runs it good but you'd need an external card
08:51 PM Tom_L: actually someone here uses the io on the rpi4 i think
08:52 PM olbastard[m]: ya.. thought i came across one showing that... but i want to learn it first before i start tinkering with tweaking for the best or what might work.. i got some working now
08:54 PM Tom_L: was bullseye running preempt-rt?
08:54 PM olbastard[m]: eventually want to redo my cnc to more rigid and better motor/spindle so i can mill aluminum, do threading,
08:54 PM olbastard[m]: yes
08:54 PM Tom_L: k
08:55 PM olbastard[m]: so i got something on my server that causes the spikes.. just have so much stuff running hard to track down what it is
08:55 PM olbastard[m]: prob some crap i installed to tinker with that i really have no use for lol
08:57 PM olbastard[m]: installed that g-code generator... Ohhh great something else to learn..
09:09 PM Tom_L: i started out with this: http://tom-itx.no-ip.biz:81/~webpage/cnc/Column_Mill_VMC.jpg
09:09 PM Tom_L: ended with this: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/chip_guards/Chip_guard5.jpg
09:14 PM XXCoder: heh I still remember your early welding pictures
09:14 PM XXCoder: that was amazing and amusing
09:15 PM Tom_L: maybe somebody will benefit from all the pics
09:33 PM olbastard[m]: bbl food time
09:57 PM * roycroft just got back from dinner
10:01 PM olbastard[m]: And you didnt give us any???!!!
10:02 PM olbastard[m]: I got biscuits in oven with gravy
10:05 PM roycroft: git your biscuits in the oven and your buns in the bed
10:05 PM roycroft: that's what i to my baby said
10:05 PM roycroft: women's liberation is a-goin to your head
10:05 PM roycroft: so get your biscuits in the oven and your buns in the bed
10:23 PM _unreal_: quite
10:23 PM _unreal_: quiet
10:24 PM olbastard[m]: yup
10:28 PM roycroft: i just figured out a way to make all my hardware and tool storage cabinets the same size
10:28 PM roycroft: the carcases, at least
10:28 PM roycroft: the drawer sizes will vary
10:28 PM Tom_L: injection molding?
10:28 PM roycroft: but this simplifies life significantly
10:29 PM roycroft: not the little boxes
10:29 PM roycroft: but the cabinets that will hold the drawers that will hold the little boxes
10:32 PM olbastard[m]: IKEA?
10:45 PM _unreal_: roycroft, trash compactor?
10:52 PM olbastard[m]: the libera chat.. I want able to log in trough that.. how do you reg there?
11:02 PM XXCoder: https://www.bestbuy.com/site/canakit-raspberry-pi-4-starter-max-kit-4gb-ram/6405650.p?skuId=6405650
11:02 PM XXCoder: 134 usd, but its a kit not ripoff scalp
11:11 PM olbastard[m]: I would like to try a raspberry pi 400 ..
11:11 PM olbastard[m]: https://www.raspberrypi.com/products/raspberry-pi-400/
11:12 PM XXCoder: saw that, nice yeah
11:13 PM olbastard[m]: imagine that with a 10 inch touckscreen and linuxcnc
11:13 PM XXCoder: 73 usd
11:13 PM XXCoder: not sure if its hardware rpi4 or theres changes
11:15 PM olbastard[m]: when i read them before .. its the same.. but placed dif on the board so gpio etc comes out the back side
11:15 PM XXCoder: so just placement?
11:15 PM XXCoder: so glad I have rpi4
11:17 PM olbastard[m]: i only got 3b+ s running automation, arcade, hotspot.. and a zero for automation of greenhouse
11:18 PM XXCoder: rpi zero 2 is as powerful as rpi3
11:39 PM _unreal_: so I ordered the rails I need
11:40 PM _unreal_: Now I just need to start cutting aluminum parts. I have everything designed.
11:40 PM olbastard[m]: new build? rebuild. upgrade?
11:40 PM _unreal_: I'm not super happy with the design. but its 10x better then what I had built before
11:41 PM _unreal_: adjusting a new build that has never been finished
11:41 PM _unreal_: lots of "LIFE" bs wont leave me alone
11:41 PM _unreal_: My stars are going to change soon. when ever the market crashes and causes a massive short squeeze. I'm likely to make a few hundred thow to a few million. I'm not kidding.
11:42 PM _unreal_: I'm real good at picking stock winners
11:42 PM _unreal_: so as far as the build goes. I'm rebuilding the XY/Z setup
11:42 PM _unreal_: all new design.
11:42 PM olbastard[m]: yup.. never fails.. its like .. ohh i have some extra money.. oops now i need a new fridge.. or now i have time off i can get stuff done... oops there is my honey do list
11:42 PM _unreal_: the BASE rail setup for the Y axis is not changing.
11:43 PM _unreal_: long story short. over the past year and a half my FAM and xwife totally bankruped me
11:45 PM _unreal_: If I get these mods done to this cnc. I'll have a cnc that is 5x the size of my current one
11:46 PM olbastard[m]: whatcha got now?
11:46 PM _unreal_: current machine is 7.75"x12.75"X 1.5" depth work area
11:46 PM olbastard[m]: 3018?
11:46 PM _unreal_: new machine will be homemade
11:46 PM _unreal_: current machine is homemade
11:47 PM _unreal_: new machine is VERY homemade as well
11:47 PM t4nk_freenode: 3018 loose screws that is ;)
11:47 PM _unreal_: I have a nice 2.2kw spindle setup but that is for a new larger build.
11:47 PM _unreal_: when I exscape my HELL
11:47 PM XXCoder: me, im been playing with hot heated air tool
11:48 PM XXCoder: its amazing
11:48 PM _unreal_: XXCoder, ?
11:48 PM XXCoder: it blows very hot air, unreal
11:48 PM _unreal_: hot air rework station?
11:48 PM _unreal_: or heat gun in general?
11:48 PM XXCoder: heat gun
11:48 PM * _unreal_ rolls eyes. I have 3
11:49 PM XXCoder: not everyone is you unreal
11:49 PM XXCoder: dont be unreal
11:49 PM _unreal_: 858d
11:49 PM olbastard[m]: okk... whats that used for?
11:49 PM _unreal_: harbor fright hot air,
11:49 PM t4nk_freenode: got a shopping list ready _unreal_? with things to buy when you hit the great profit on the stock market?
11:49 PM _unreal_: an expensive one I dont recall the modle of, needs a new coil.
11:49 PM _unreal_: and I have a really cool radio shack hot air run
11:50 PM _unreal_: the 858d is a SMD hot air station
11:50 PM XXCoder: mines not even as fancy as hf lol. its in box with chinese words on it
11:50 PM XXCoder: very cheap
11:50 PM _unreal_: t4nk_freenode, ya A HOUSE
11:50 PM t4nk_freenode: buy a cnc machine!
11:50 PM t4nk_freenode: big as a house
11:51 PM * roycroft senses the hot air, and not for the first time
11:51 PM _unreal_: XXCoder, I do a lot of PCB stuff. now and then and that hot air station is a dream
11:51 PM _unreal_: XXCoder, if you dont have a hot air station I strongly suggest the 858d
11:51 PM _unreal_: its cheap and WORKS really well
11:52 PM XXCoder: sure i dont do electrics though
11:52 PM _unreal_: I use it for everything from SMD add/remove, to heat shrink to anything that needs
11:52 PM XXCoder: i got it for 3d print processing and some tricks
11:52 PM XXCoder: and yeah heat strunk also
