04:53 AM Tom_L: must be the Inputs / Outputs not done yet
05:07 AM travis_farmer[m4: Morning ☕️ (just woke up again...)
05:26 AM travis_farmer[m4: i think my package will be arriving today :-) :-)
05:38 AM JT-Cave: rooster just crowed
05:44 AM JT-Cave: how close is waterville?
06:05 AM travis_farmer[m4: waterville is the closest distro center, just before it reaches Farmington
06:17 AM JT-Cave: here goes nothing doing apt dist-upgrade
06:18 AM JT-Cave: I hope it doesn't break this pc
06:18 AM * travis_farmer[m4 wishes JT luck
06:47 AM JT-Cave: I'm still here :)
06:49 AM travis_farmer[m4: :-)
06:50 AM MikeDub[m] is now known as mikedub0[m]
07:23 AM JT-Cave: Tom_L, pull mesact2
07:24 AM Tom_L: how far?
07:26 AM Tom_L: are those the tests you've done?
07:27 AM JT-Cave: the info tab has the current tests that need testing
07:27 AM JT-Cave: ?how far?
07:28 AM Tom_L: to pull it :)
07:29 AM Tom_L: so if there are values in the next joint they will be overwritten?
07:30 AM JT-Cave: yup
07:34 AM Tom_L: it's not saving position feedback in the ini
07:34 AM Tom_L: under settings
07:35 AM Tom_L: or it's not reloading it
07:36 AM Tom_L: the ini says POSTION_FEEDBACK = False after selecting one and building
07:37 AM JT-Cave: ok
07:37 AM JT-Cave: build from scratch or update?
07:38 AM JT-Cave: makes a big difference they are two different functions
07:38 AM Tom_L: this was an update i built last night but aparently either way it doesn't save it
07:39 AM JT-Cave: [DISPLAY]
07:39 AM JT-Cave: DISPLAY = axis
07:39 AM JT-Cave: PROGRAM_PREFIX = /home/john/linuxcnc/nc_files
07:39 AM JT-Cave: POSITION_OFFSET = RELATIVE
07:39 AM JT-Cave: POSITION_FEEDBACK = COMMANDED
07:39 AM JT-Cave: I'm not getting that...
07:39 AM -!- #linuxcnc mode set to +v by ChanServ
07:47 AM JT-Cave: and remember update does not update the ini it only displays it in the Info tab
07:47 AM JT-Cave: for testing
07:47 AM Tom_L: i built config
07:47 AM Tom_dev: [DISPLAY]
07:47 AM Tom_dev: DISPLAY = axis
07:47 AM Tom_dev: EDITOR = geany
07:47 AM Tom_dev: PROGRAM_PREFIX = /home/tom/linuxcnc/nc_files
07:47 AM Tom_dev: POSITION_OFFSET = RELATIVE
07:47 AM Tom_dev: POSITION_FEEDBACK = False
07:47 AM Tom_L: i was getting that last night and today
07:47 AM JT-Cave: did you select POSITION_FEEDBACK?
07:47 AM Tom_L: yes
07:47 AM Tom_L: ok so i saved it under a new name and it's what it should be. lemme edit it now
07:47 AM Tom_L: so a new one works
07:51 AM JT-Cave: it's in traj
07:51 AM Tom_L: ok
07:51 AM Tom_L: my search isn't set right
07:51 AM * travis_farmer[m4 waits for the mail person to come :-)
07:52 AM JT-Cave: update ini changes from commanded to actual but remember it does not write to the ini file yet!
07:52 AM Tom_L: oh
07:53 AM JT-Cave: so I think it's time to do that
07:53 AM Tom_L: but it's in the initial ini i built
07:53 AM JT-Cave: it was easier to just open the same ini over and over and see the changes in the info tab
07:53 AM Tom_L: just False
07:53 AM JT-Cave: is that an old one?
07:53 AM JT-Cave: now it works
07:53 AM Tom_L: no i built it last night
07:53 AM Tom_L: 2.0
07:54 AM Tom_L: and pulled this morning
07:54 AM JT-Cave: try again, it saves postion feedback for me with a new config and updates the ini in the info tab
07:55 AM JT-Cave: ok it writes to the ini file when updating now
07:55 AM * JT-Cave starts his chicken day
07:58 AM -!- #linuxcnc mode set to +v by ChanServ
07:59 AM Tom_itx: position_feedback updates now
07:59 AM Tom_itx is now known as Tom_L
08:07 AM * travis_farmer[m4 is still waiting for the mail... (9AM usually) not sure why i am so excited, but there i am... :-)
08:08 AM Tom_L: pitch a tent by the box
08:08 AM travis_farmer[m4: LMAO!!!!
08:10 AM travis_farmer[m4: MAIL!!!!
08:40 AM travis_farmer[m4: the package has landed! along with another item (not from MesaUS) i will get a picture of in a bit... :-)
09:06 AM perry_j1987: morning
09:46 AM * travis_farmer[m] uploaded an image: (1655KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/lmWAJBKBvtkJUnqzXybauanb/20230615_104240.jpg >
09:46 AM travis_farmer[m]: New laser, beside old smaller laser
09:47 AM perry_j1987: where's the shark you're going to put it on
09:48 AM travis_farmer[m4: my CNC router table :)
09:49 AM travis_farmer[m4: but anyway, it is 86F in my shop, so i am heading back in the house now, and plan out a mount for it :-)
09:52 AM dougemes[m] is now known as dougemes0[m]
10:03 AM roycroft: the baby shark?
10:07 AM roycroft: my shaper products are out for delivery
10:07 AM roycroft: if they actually are delivered today, i may cut some air tonight
10:15 AM travis_farmer[m4: so i am not the only one getting much awaited packages today. :-) though, i think yours is a tad more expensive than mine... ;-)
10:15 AM roycroft: probably
10:15 AM roycroft: but mine should pay for themselves soon
10:15 AM roycroft: i hope that's the case with yours
10:15 AM travis_farmer[m4: i hope mine will too :-)
10:17 AM travis_farmer[m4: just need to figure out a way to mount it. i have lightburn already. the laser i don't really need a spoilboard for engraving, so i can produce with it much sooner than waiting to move into the new shop
10:18 AM roycroft: i have a lot to do at work today, and i still haven't figured out the most efficient way to get my sldprt files converted to svg for the origin
10:18 AM roycroft: but more than likely i'll just cut out a circle or something to start with
10:18 AM roycroft: using the on-board cad tool
10:19 AM travis_farmer[m4: i don't use solidworks, so i can't be of much help...
10:19 AM roycroft: that's not the issue at all
10:19 AM roycroft: it's the convert to svg bit
10:23 AM roycroft: finding a home for the stuff is also going to be a challenge
10:35 AM avakato[m] is now known as avakato0[m]
10:37 AM Tom_L: roycroft, i can help you with that
10:37 AM roycroft: i should imagine you can
10:48 AM JT-Shop: lol
11:01 AM roycroft: i suspect you would find the shaper origin annoying, tom_l
11:01 AM roycroft: i've discovered that it has a kind of apple-like cult aura surrounding it
11:02 AM roycroft: if i'm honest i hope it's really intuitive enough that i don't have to hang out on the shaper forums too much, because they are pretty annoying
11:06 AM JT-Shop: lol
11:06 AM travis_farmer[m4: i think i missed something
11:07 AM JT-Shop: nap time
11:11 AM travis_farmer[m4: i am liking the idea of this new laser, though i can't test it until i have the correct safety glasses
11:11 AM roguish[m]: JT-Shop: hey wanna good driving book??? https://www.amazon.com/Driving-Competition-Alan-Johnson/dp/0393600114/ref=tmm_pap_swatch_0?_encoding=UTF8&qid=1686845417&sr=8-5
11:12 AM roguish[m]: it's absolutely outstanding
11:12 AM roycroft: don't put your eye out with it!
11:13 AM travis_farmer[m4: that's the idea behind waiting for the safety glasses ;-)
11:13 AM roycroft: we went to a new brew pub/pizzaria for dinner last night
11:13 AM roycroft: they had some cute local names for their beers
11:14 AM roycroft: i had a pint of "one-eyed willie pale ale"
11:14 AM roycroft: an homage to the goonies, in case you don't get the refernce
11:14 AM roycroft: the beer and the pizza were both good
11:36 AM bradcool[m] is now known as bradcool_220[m]
11:38 AM travis_farmer[m4: hmmm, i think when i figure out the focal length of my laser, i should mount a small mechanical limit switch on it, and wire it to E-stop to prevent an accidental crash... just a thought
11:46 AM JT-Shop: roguish[m], we are going to the Ron Fellows driving school for C8's
11:51 AM JT-Shop: I need a bigger monitor for the laser... lightburn takes up more space than there is
11:52 AM travis_farmer[m4: that's always a PITA..
11:53 AM roguish[m]: JT-Shop: i got that book way back, when I was enduro kart racing.
11:54 AM roguish[m]: driving school..... just have lots of fun
11:55 AM JT-Shop: they do a special for new Corvette owners and it sounds like fun, the wife can ride with the instructor if she wants and she can go to all the classrooms
11:55 AM roguish[m]: very cool
11:59 AM roguish[m]: check this ancient picture. not mine, but mine was very similar. motor was a modified McCullah chain saw motor. 100cc .... would rev over 10k, probably about 15hp. 120mph flat on your back, feet out front.. got to race at the old Ontario and Riverside raceways, and Willow Springs. http://www.lostenduros.com/wp-content/uploads/2011/04/Enduro2.jpg
12:00 PM JT-Shop: yup that's nuts for sure
12:02 PM roguish[m]: fastest i've ever gone.... the 100cc mccullah class was the slowest. the 135cc euro motors could get up past 150 mph easily.
12:02 PM JT-Shop: holy crap
12:02 PM roguish[m]: that's why I got the book. to learn how to corner at very high speed
12:03 PM Tom_L: roguish[m], i had one of those but never 'raced' it
12:04 PM Tom_L: just for fun
12:04 PM roguish[m]: Karts are even more amazing now. practically all F1 drivers come from a kart background. like Lewis Hamilton
12:04 PM Tom_L: they've come a long ways for sure
12:04 PM roguish[m]: mine was strictly race.
12:04 PM Tom_L: they have a lake here they close off for a cart race and the next week they have the scca
12:05 PM roguish[m]: they are the highest speed and biggest pucker factor per dollar.............
12:05 PM Tom_L: https://www.kart.org/tracks/lake-afton
12:06 PM Tom_L: yeah just avoid guard rails
12:06 PM roguish[m]: I spun into the hay bales once at Riverside.....scary fun.
12:06 PM Tom_L: they have the karts first then add barrels & more tires for scca
12:07 PM Tom_L: for those that can't keep it on the pavement
12:07 PM roguish[m]: sit up karts were called 'sprint' karts, laydown karts 'enduro'
12:07 PM Tom_L: mine was more enduro style i think
12:07 PM Tom_L: had saddle tanks like your pic shows
12:07 PM roguish[m]: did not have gearboxes back then. but now do
12:08 PM Tom_L: i'd put a short sprocket on it and find an industrial parking lot on the weekends
12:08 PM * travis_farmer[m4 had a dirt-bike growing up, but always wanted a off-road cart...
12:08 PM Tom_L: mine didn't
12:08 PM roguish[m]: I put rear view mirrors on my tanks. the first around Cal. next year more had 'em
12:08 PM Tom_L: mine was pretty old school
12:09 PM Tom_L: still fast and fun
12:09 PM roguish[m]: https://www.superkartsusa.com/
12:09 PM Tom_L: they're a blast to drive
12:10 PM Tom_L: what do they use for engines now?
12:10 PM roguish[m]: no clue
12:10 PM Tom_L: mac was pretty much it back then
12:12 PM Tom_L: https://www.sgm-velox-kart.com/gokart/index.php/en/250-cc-superkart.html
12:12 PM Tom_L: come a long ways
12:13 PM roguish[m]: a 250cc. that's big.
12:13 PM Tom_L: no kidding
12:13 PM Tom_L: for that weight
12:14 PM roguish[m]: and huge HP
12:14 PM Tom_L: power/weight ratio crazy
12:15 PM roycroft: i need to get new mirrors for my pickup
12:15 PM roycroft: that's on my list of upgrades
12:15 PM roguish[m]: there used to be one called a 'Komet' I think 125cc, maybe 135cc. could spin 17k out of the box, and like 25hp
12:15 PM roycroft: i want some telescoping ones, so i can push them out when hauling a trailer, and pull them back in when i'm not
12:16 PM Tom_L: i used to get like 5hp from my .65cc boat engines
12:16 PM roycroft: i used to have trailer mirrors for my old chevy pickup - they were a big hassle to install and uninstall
12:16 PM roycroft: they worked well, but it took twice as long to install and adjust the mirrors than it took to hook up the trailer and check the lights
12:17 PM Tom_L: https://www.mantuamodel.co.uk/products/ops-engines/marine/1601/op-67-marine-engine-drum-detail
12:17 PM adragomir[m] is now known as adragomir0[m]
12:17 PM Tom_L: those were the best imo
12:17 PM travis_farmer[m4: i used to have a go-cart with a 1200cc engine :-)
12:18 PM Tom_L: and you lived to tell us
12:18 PM Tom_L: even more amazing :)
12:18 PM travis_farmer[m4: the one on the right...
12:18 PM * travis_farmer[m4 uploaded an image: (8212KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/EWogjDCuQseguzYKRkWxAXwG/IMG_0072.JPG >
12:19 PM Tom_L: pfft
12:19 PM travis_farmer[m4: LMAO
12:35 PM JT-Shop: going to Crumpie's 11-Point Smokehouse today
12:35 PM JT-Shop: I hope their open lol
12:37 PM Tom_L: you might check first
12:37 PM Tom_L: a google indicates maybe not
12:37 PM Tom_L: Hours:
12:37 PM Tom_L: Thursday 3:30–9 PM
12:38 PM Tom_L: Couch, MO
12:39 PM Tom_L: odd hours
12:39 PM Tom_L: mon-wed closed
12:40 PM roycroft: you sure eat out a lot these days
12:40 PM JT-Shop: they have been like that for years, the only one worse than that is the Clarktoinan
12:40 PM roycroft: i used to eat out all the time, but the pandemic stopped that
12:40 PM roycroft: my pocketbook liked that, and i've never gotten back into the habit since
12:41 PM JT-Shop: I seem to be retired now... so eating out is fun
12:41 PM roycroft: it is fun
12:42 PM JT-Shop: so to have a real test card for both raster and vector you need an array of small images and an array of squares?
12:44 PM roycroft: a gradient square would be an ok raster test
12:44 PM JT-Shop: ok
12:44 PM roycroft: but yeah, you should probably use some kind of image for the raster test, and a solid square for vector
12:44 PM roycroft: i haven't done any raster image work on my laser
12:45 PM roycroft: maybe some day, but i have no need for that now
01:01 PM Mleekush[m] is now known as mleekush0[m]
01:01 PM perry_j1987: hey if I want to start doing cam to the model dimensions and then fine tune it with cutter comp or fudging the diameter of the cutter in linuxcnc? what do i need to do
01:02 PM perry_j1987: kinda getting tired of the teadiousness of going back and forth to the cam software to change stock to leave and then exporting gcode over and over again to dial things in haha
01:02 PM Tom_L: i generally don't use cutter comp but rather fix the model
01:02 PM Tom_L: get it right the first time :)
01:03 PM perry_j1987: what is there to fix on the model
01:03 PM perry_j1987: if you want a quarter inch hole the model should have a quarter inch hole right? heh
01:03 PM Tom_L: you could also fudge a little with the tool diameter
01:04 PM perry_j1987: i dont have diameters in any of my tool table right now
01:04 PM Tom_L: lathe?
01:04 PM perry_j1987: mill
01:04 PM Tom_L: oh, you're just not using the tool table
01:05 PM Tom_L: do you program the tool center or the edge?
01:05 PM Tom_L: i've found you can get into trouble on tight radius with comp and tool diameter
01:08 PM perry_j1987: in fusion 360 i just leave it to default at compensation in computer
01:08 PM JT-Shop: yup
01:08 PM perry_j1987: so fusion360 is figuring it out right now
01:14 PM perry_j1987: is there anything special i need in my linuxcnc config to start playing around with this?
01:27 PM * JT-Shop needs to change a bunch of burned out tubes
01:27 PM travis_farmer[m4: interesting... when i ran my spindle VFD via ModBus, it maxed out at 400hz (12000RPM), and that was with the set speed at 24000rpm... so i assumed 400Hz was 24000rpm. today, running analog mode (0-10Vspeed setting), it tops out at 800hz. i thought it was running overspeed, until i checked the spindle manual, that said 800hz is 24000rpm. so i guess that's that, it is running as it should, now. :-)
01:28 PM perry_j1987: still running vacuum tubes eh JT-Shop
01:28 PM JT-Shop: till I run out in seldom used fixtures yes
01:28 PM JT-Shop: travis_farmer[m4, awesome
01:29 PM roycroft: i have several tube radios
01:29 PM travis_farmer[m4: and i have good analog speed feedback :-)
01:30 PM roycroft: even my "modern" (circa 1972) mcintosh tuner has a magic eye tuning tube
01:30 PM JT-Shop: light fixtures that I use a lot are all led
01:31 PM roycroft: i need to find some led panels that can be had in arbitrary sizes
01:31 PM roycroft: ideally, panels that can be cut to size would be what i want
01:31 PM roycroft: does anyone know of such things?
01:32 PM roycroft: also, i need some really small cnc router cutters with fairly long cutting lengths that work well with wood in a cnc router
01:32 PM roycroft: i'm taking about 2mm or 3/32" diameter, cutting length of 10-12mm or ~7/16"
01:33 PM roycroft: spiral up would be ideal, but straight would be ok
01:33 PM pcw--home: I bought a tube radio at the flea market last Sunday
01:34 PM JT-Shop: does it work?
01:34 PM pcw--home: I need to figure out how to fix its speaker
01:34 PM pcw--home: Its a 1932 Jackson bell Peter Pan (for $2.00)
01:35 PM JT-Shop: wow that's old
01:35 PM JT-Shop: battery powered?
01:35 PM roycroft: my collet options are 1/8", 1/2", 3mm, 6mm, and 8mm
01:35 PM pcw--home: 120VAC
01:35 PM roycroft: i don't have a jackson radio, but i do have a jackson tube tester that still works great
01:36 PM roycroft: and it's an actual tube tester - it was used in repair shops
01:36 PM roycroft: vs. the tube sellers that one would find in department stores/hardware stores back in the day
01:36 PM roycroft: pre-1927 radios were mostly battery powered
01:37 PM roycroft: and then there were some "portable" radios that started coming out in the late '30s that were battery powered
01:37 PM roycroft: if you chose to lug the big batteries around with you
01:38 PM pcw--home: This one is quite small for its age
01:39 PM roycroft: yeah, that wsa the age of cathedral radios for table tops, and big consoles for the primary living room radio
01:39 PM pcw--home: It has an uncalibrated tuning dial so there's a little drawer on the bottom with a cheat sheet
01:40 PM pcw--home: Speaker needs reconing
01:42 PM roycroft: aah, it's a small cathedral style
01:42 PM roycroft: at least you only have one tuning dial to deal with
01:42 PM pcw--home: yeah small but heavy... Transformer operated
01:47 PM roycroft: i have an atwater-kent model 20 (c. 1924) that is a pre-superheterone design with three tuning phases, so you have to fiddle with three tuner dials to dial in a station
01:47 PM roycroft: superheterodyne, rather
01:47 PM roycroft: it's also battery-powered
01:47 PM roycroft: but ac adapters can be had/made, of course
01:58 PM travis_farmer[m4: does it do Bluetooth? ;-)
02:00 PM roycroft: it does teh am, but not teh fm
02:01 PM roycroft: http://www.atwaterkentradio.com/ak20c.htm
02:05 PM * travis_farmer[m4 thinks of a way to add A/C to the shop, so it would be possible to work in there when hot...
02:05 PM roycroft: wrap a giant tee-shirt around the outside of the shop, wet it down really well with a hose, and blow a fan onit
02:06 PM travis_farmer[m4: i said A/C, not swamp cooler ;-)
02:07 PM pcw--home: At one time I had somewhat newer Atwater Kent in a metal case but same tuning
02:09 PM roycroft: i'm really glad mine is a wooden case model
02:09 PM roycroft: the all metal case ones are ok
02:09 PM roycroft: and the paint on them is actually really nice
02:09 PM pcw--home: Yeah that's neat
02:10 PM roycroft: but i like the wooden ones better
02:10 PM roycroft: i don't know if mine works or not
02:10 PM roycroft: it has the original tubes, which are pretty rare these days
02:10 PM roycroft: but it needs a high impedence (2k ohm) speaker, and all my old radio speakers are 600-750 ohms
02:11 PM roycroft: it worked when i got it 35 or so years ago
02:11 PM travis_farmer[m4: likely the caps are bad, or about to be so
02:12 PM roycroft: my oldest radio that i know is still working is a 1927 radiola model 17
02:12 PM roycroft: well, when it was last known working, it was already about 70 years old, on the origial caps
02:13 PM roycroft: and i doubt it had been used continually the entire time
02:13 PM roycroft: but you're right, they cold quite possibly be bad
02:14 PM pcw--home: This is the model I found: https://radioattic.com/item.htm?radio=0260393
02:14 PM roycroft: https://radioattic.com/soldradios/sold_radios_2007/Boyd_Radiola_17_(1927).jpg
02:14 PM roycroft: there's an example of the radiola
02:14 PM roycroft: it also has a nice wooden case, and it weighs about a ton
02:15 PM roycroft: is yours in good condition, pcw--home?
02:15 PM roycroft: $2 was a real steal for that
02:16 PM pcw--home: All there, but the speaker and cloth are torn
02:16 PM roycroft: it should go for at least $50 non-working condition, in fair cosmetic condition
02:16 PM pcw--home: and Peter pans horn was broken/missing but I found it inside
02:16 PM roycroft: that's easy to fix
02:17 PM travis_farmer[m4: i have seen some nice looking (reproduction) cloth on eBay, for repairs
02:17 PM roycroft: and speaker cloth is commonly damaged
02:17 PM roycroft: there are radio restoration shops that have period-appropriate, acoustically transparent replacement cloth
02:17 PM roycroft: the speaker might be a bit difficult to repair or replace, depending on what it is
02:17 PM roycroft: especially if it's not a permanent magnet coil
02:18 PM pcw--home: the speaker cone is probably the worst thing (plus whatever electrical repairs/recapping is needed)
02:18 PM travis_farmer[m4: https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2540003.m570.l1313&_nkw=vintage+speaker+cloth&_sacat=0
02:18 PM pcw--home: Yeah its a dynamic (lansing)
02:19 PM pcw--home: Some of those cloths look really close
02:21 PM roycroft: i have a 1939 montgomery ward airline radio in my living room that i listen to all the time
02:21 PM roycroft: it works great
02:21 PM travis_farmer[m4: i have a bluetooth speaker in my shop i listen to a lot ;-)
02:22 PM roycroft: https://www.ebay.com/itm/185937017333
02:23 PM roycroft: that model, except it's in much better condition - it's really clean
02:23 PM travis_farmer[m4: a project i would love, would be to find a wood radio chassis, where the electronics are brain-dead, and convert it to bluetooth. i love the look of old wood radios :-)
02:24 PM roycroft: a bunch of wingnutters are trying to start a big boycott of ford now
02:24 PM roycroft: i find it pretty funny
02:25 PM roycroft: ford are one of several car manufacturers who are dropping am radios in their vehicles, due to lack of demand
02:25 PM roycroft: the wingnutters are convinced that the government are forcing ford to do it, because their jesus and wingnut programs are on am
02:26 PM roycroft: i'm not sure where they got that, as "the government" has done nothing at all to discourage am radio
02:26 PM travis_farmer[m4: the interstate here in Maine uses AM broadcast for emergency messages
02:26 PM roycroft: nor do i understand why they have singled out ford, since several manufacturers are doing the same thing
02:26 PM roycroft: but it's pretty funny
02:27 PM roycroft: and my understanding is that the stock radio will not have am, but it can be added, at least with some manufacturers, as an option
02:28 PM roycroft: the bud light boycott has been very effective, btw
02:28 PM roycroft: negro model, a mexican import beer, has just surpassed bud light and is now the #1 beer in sales in the united states
02:28 PM roycroft: negro modelo, that is
02:29 PM roycroft: oh the irony
02:29 PM roycroft: anyway, i don't think am is going away any time soon
02:29 PM roycroft: especially in places where the ground isn't flat
02:33 PM roycroft: travis_farmer: we use low power am for road advisories here, too
02:34 PM travis_farmer[m4: am does travel a long ways
02:35 PM roycroft: especially at night
02:35 PM travis_farmer[m4: yup
02:37 PM roycroft: to get back remotely on topic, i'd still like some pointers to small cutters for wood
02:38 PM roycroft: i was directed to amana, but when i went there the choices were almost overwhelming
02:38 PM roycroft: i'm going to be cutting thin slots in end grain, primarily
02:38 PM roycroft: mostly on fairly hard woods
02:43 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/etching/mills1.jpg
02:43 PM Tom_L: i tried some of those on pcb but decided etching was much easier
02:45 PM roycroft: those look fairly short
02:46 PM roycroft: my slots will be rather deep, compared to the width
02:46 PM roycroft: and that's the problem
02:47 PM roycroft: and since shaper seem to be the apple of woodworking machines, if i ask about it on their forums the response i'll likely get is "redesign your part to use the tooling we like"
02:47 PM roycroft: actually, that would be the good answer
02:47 PM roycroft: the more likely one would be "why don't you just go to shaperhub, download the plans for one of our projects, and build that instead"
02:49 PM roycroft: which i can relate to, as it's air-cooled volkswagen mentality - the journey is more important than the destination - but that mentality does not apply to running a business
03:13 PM Tom_L: i doubt you're gonna find cutters that small with much more flute length
03:14 PM Tom_L: i have some .063 with .125 cut length
03:15 PM Tom_L: and btw my air-cooled 68 was quite reliable
03:16 PM Tom_L: the cutters i look for aren't necessarily for wood though
03:17 PM Tom_L: if the slots are straight maybe a slitting saw would work better
03:17 PM Tom_L: maybe not...
03:28 PM roycroft: a slitting saw probably won't work well in a shaper origin
03:28 PM roycroft: i'm looking at the design now
03:28 PM roycroft: i *may* be able to do it with 1/8" cutters
03:28 PM roycroft: and i can easily get the depth i need with a cutter that size
03:29 PM XXCoder: roy yeah some products do get cults and yep its annoying
03:29 PM roycroft: the slots, with my current design, are 5/32" wide
03:29 PM XXCoder: because often enough answer is "its your fault not holy product"
03:29 PM roycroft: i kind of expected it, xxcoder
03:29 PM roycroft: i'm just disappointed that my expectation seems to be met and exceeded
03:29 PM XXCoder: it does seem to be well made yeah
03:30 PM roycroft: to many in the shaper cult, the whole point of having an origin is to play with an origin
03:30 PM roycroft: not to make stuff with it
03:30 PM XXCoder: fun. unrelated, curious if you can cut clean cardboard with your laser machine
03:30 PM roycroft: anyway, i was originally going to get a special table saw blade made with a 5/32" wide kerf
03:31 PM roycroft: but the setup every time i need to use it would take a long time, and i'd have to do a bunch of test cuts to dial in the setup
03:31 PM roycroft: with the origin i should be able to avoid almost all of that, other than the initial dialing in
03:31 PM roycroft: i haven't tried cardboard with the laser yet
03:32 PM roycroft: i'm going to at some point
03:32 PM roycroft: where i'm at with that right now is i've done some initial testing and figured out some settings for some of my work, but i want to finish the enclosure and get it set up in its permanent home before i do much more with it
03:32 PM roycroft: and that is literally a matter of letting paint dry now
03:33 PM XXCoder: nice
03:33 PM roycroft: what i found out is that latex paint with a lot of pigment in it takes much longer to cure than paint with a small amount of pigment
03:33 PM XXCoder: why I asked is that I want to evenually want to cut waste cardboards into cross sections and build small statues for fun
03:33 PM roycroft: so it's been suggested that i wait a month after applying the last color coat before sanding it and spraying clear on it
03:34 PM roycroft: i'm in that waiting period now
03:34 PM roycroft: i have about $60 in materials and 12 or so hours of time into the failed first attempt at painting it
03:34 PM roycroft: i don't want another failure, so i'm going to wait
03:34 PM Tom_L: roycroft, any cutter under .125 will have a .125" shank
03:35 PM roycroft: i can get a 1/8" collet for my spindle
03:35 PM roycroft: collets are available in 1/8", 1/4" 3mm, 6mm, and 8mm
03:35 PM XXCoder: makes sense on paint
03:35 PM roycroft: the machine comes with a 1/4" collet, and i have an 8mm collet for a festool router that should fit
03:35 PM roycroft: but i'll get a 1/8" collet if i need it, and i'm sure i will
03:36 PM roycroft: i'll probably just buy the collet set, so i have them all
03:36 PM roycroft: i wish it used an er collet, so i could use whatever shank i have, up to the 8mm limit
03:43 PM Dolence[m] is now known as dolence0[m]
03:56 PM perry_j1987: cant use g53 with cutter comp? why
04:04 PM Tom_L: perry_j1987, maybe something to do with it not being modal?
04:05 PM Tom_L: as it must be programmed on each line that uses it
04:07 PM Tom_L: i use it to send the machine home instead of G28
04:10 PM perry_j1987: K switched off g53 retracts
04:10 PM perry_j1987: now its saying cannot change control mode with radius comp turned on
04:16 PM perry_j1987: i reemember why i stopped trying this in the past
04:16 PM perry_j1987: just error after error after error
04:17 PM Steirerman[m] is now known as steirerman0[m]
04:22 PM Tom_L: if you're using G53 for retracts use G28
04:22 PM Tom_L: and see what that does to the rest of it
04:25 PM Tom_L: i don't get that problem since i don't use comp
04:29 PM perry_j1987: ya i changed it to something other than g53
04:29 PM perry_j1987: its complaining about arc moves and gouging even though im just doing a straight path. must be leadin/leadout or smething?
04:30 PM Tom_L: likely so
04:30 PM Tom_L: some very short path... shorter than the tool diameter
04:31 PM Tom_L: i might suggest trying to edit the tool diameter in the table over using comp
04:31 PM Tom_L: see if that's a workable solution for you
04:32 PM Tom_L: just remember to reload it
04:33 PM perry_j1987: what do you mean
04:33 PM perry_j1987: that tool diameter is only read in the tool table if you post with in-control
04:33 PM perry_j1987: so it uses g41 / g42 lines etc right?
04:33 PM Tom_L: on a .500 cutter, instead of adding/subtracting comp enter .501 or .499 as the cutter diameter
04:33 PM Tom_L: etc
04:34 PM perry_j1987: ya thats all I wanted to be able to do was use the tool diameter field in the tool table to adjust the fit etc
04:34 PM Tom_L: you don't need comp for that
04:34 PM Tom_L: just program the nominal size without comp
04:35 PM Tom_L: then change the tool table diameter to suit
04:35 PM perry_j1987: i thought that it disregarded that field in the tool table unless you were using cutter comp
04:35 PM Tom_L: no it has to know what size cutter you have
04:35 PM Tom_L: on my programs i program the tool edge not the center
04:36 PM Tom_L: experiment with it
04:36 PM perry_j1987: ya fusion 360 in-computer programs to the tool center and you manage your tool library in cam
04:36 PM Tom_L: i think you'll find it a little easier..
04:36 PM Tom_L: but the output code will allow for the cutter radius
04:37 PM perry_j1987: what tells it that?
04:37 PM perry_j1987: the coordinates are totally different
04:37 PM Tom_L: aparently in f360, the combination of cutter path and cutter size
04:37 PM Tom_L: mine works a little different
04:39 PM Tom_L: for example: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A8_new/A8_fixture.jpg
04:40 PM Tom_L: the green is the actual part size and the other colors are the programmed offset path
04:41 PM Tom_L: with the arc leadin/out
04:47 PM Tom_L: the end result is the same gcode or close to it
04:49 PM Tom_L: perry_j1987, the f360 tool library would stay the same. you would adjust it in the lcnc tool table
04:49 PM Tom_L: and just tell f360 to turn off comp
04:49 PM perry_j1987: played with in control, and wear so far
04:49 PM Tom_L: however you do that in that program
04:49 PM perry_j1987: both give a slew of errors if i try to run the program
04:50 PM perry_j1987: im using the stock linuxcnc post processor as well
04:50 PM Tom_L: is it still outputting G41-42?
04:51 PM Tom_L: i don't know f360. you may have to turn that off per cutter? i don't know
04:51 PM Tom_L: somewhere there will be a toggle for it though
04:52 PM Tom_L: it would likely be at a tool change
04:52 PM Tom_L: in the code
04:52 PM perry_j1987: looking
04:53 PM Tom_L: as you wouldn't want it on for something like a drill etc
04:53 PM perry_j1987: wear apparently lets the tool path be what it is and then if you want to tell the controller your tool is slightly smaller you just put the difference in the diameter field
04:54 PM Tom_L: in f360?
04:54 PM perry_j1987: ya
04:54 PM Tom_L: don't adjust for it in f360. keep that path nominal
04:54 PM perry_j1987: in f360 there's a dropdown for in-computer (thats letting f360 manage everything and outputting premade gcode)
04:55 PM Tom_L: then edit the lcnc tool table diameter
04:55 PM perry_j1987: then there is in-control and thats letting linuxcnc figure out tool diameters
04:55 PM perry_j1987: then there is wear which is like a combo i guess and you just put in the small amount you want to cange the tool behavior
04:56 PM Tom_L: i personally wouldn't use those
04:56 PM Tom_L: everyone has a different idea about programming
04:57 PM Tom_L: that's likely where your errors are being introduced
04:57 PM Tom_L: if i'm trying to cut a .250 blend with a .501 cutter it will error
04:57 PM Tom_L: but
04:58 PM Tom_L: if i cut the .250 blend using the .500 generated path it should work
04:58 PM perry_j1987: this is what im reading " Use Wear v.s In machine, a standard cam (In computer) tool path only posts a g43 line for in control length offset. i.e fusion is doing the radial side comp and the control is handling the length offset. If you use wear compensation, then fusion still does the radial/side comp but the code now added a g41/g42 so the control is being told to do length and side compensation even tho fusion did a the
04:58 PM perry_j1987: radial/side comp... this means the value in the dia offset is just the difference from spec v.s actual. i.e All tool paths can be marked as wear and as long as the dia is zero on the offset page for the given tool, the code runs the same as standard. but if you need to walk a tolerance in then you just add a small neg value in the dia field like -.001mm then the controller offsets the tool path...Think of it as a fine adjustment
04:58 PM perry_j1987: or stacked compensation fusion does 99% of the compensation and the wear/dia value is the controller offsetting the tool path for a final tweak. great for tool deflection or even material change or tool wear etc."
04:58 PM Tom_L: but change the .500 cutter in lcnc tool table instead
04:58 PM Tom_L: no one will be the wiser
04:59 PM Tom_L: so acording to that, don't use the wear comp
04:59 PM Tom_L: that adds in the G41 or G42
05:02 PM perry_j1987: ok selected none in the dropdown
05:02 PM perry_j1987: comparing that to the other gcodes
05:02 PM Tom_L: experiment with it a bit
05:02 PM perry_j1987: ya
05:02 PM Tom_L: cut a square block and measure it
05:03 PM Tom_L: keep things nominal in f360 though
05:04 PM roycroft: my work day is over
05:05 PM roycroft: time to tidy up the shop and make some space for the new toys
05:05 PM perry_j1987: hmm
05:05 PM perry_j1987: is this g43 for z length affecting things?
05:05 PM Tom_L: no
05:05 PM Tom_L: you need that for the tool length offset
05:05 PM perry_j1987: im still getting a slew of errors
05:05 PM perry_j1987: it complains about having g54 in the code
05:05 PM Tom_L: shouldn't
05:06 PM Tom_L: that's a default offset
05:06 PM perry_j1987: so i comment that out since im already in g54 and then it complains about other cannot change control mode with cutter comp enabled
05:06 PM Tom_L: are there G41 42 in the code?
05:06 PM Tom_L: if so you didn't turn it off in f360
05:07 PM perry_j1987: nope
05:07 PM perry_j1987: no g41 or 42
05:07 PM Tom_L: what about G40?
05:08 PM perry_j1987: no g40
05:08 PM Tom_L: 'it complains'
05:08 PM Tom_L: who is complaining? lcnc or f360
05:09 PM perry_j1987: linuxcnc
05:09 PM Tom_L: did it regenerate the paths after you made the changes?
05:09 PM Tom_L: it may still have the compensated path
05:10 PM Tom_L: f360 that is
05:11 PM perry_j1987: ya
05:14 PM Tom_L: dunno then. i messed with f360 in it's infancy and decided it wasn't for me
05:14 PM Tom_L: others seem to have great success with it
05:16 PM Tom_L: add a G40 to the top of the generated code and see what happens
05:16 PM Tom_L: in case lcnc has comp still on
05:16 PM Tom_L: i don't remember if it's modal or not but likely is
05:17 PM perry_j1987: just shut down linuxcnc and restarted and homed
05:17 PM perry_j1987: now i can run the code without it complaining lol
05:17 PM Tom_L: try adding the G40
05:17 PM Tom_L: it likely had comp still on
05:17 PM Tom_L: i think it's off on boot
05:18 PM Tom_L: if you're running axis, you can check that in the mdi screen for active gcodes
05:19 PM perry_j1987: ya i wish axis had tooltips when you hover over all those active gcodes heh
05:19 PM Tom_L: now if it's under/oversize just change the cutter diameter in lcnc tool table to suit
05:20 PM perry_j1987: so now i have some gcode that is the centerline of the tool path. what command tells linuxcnc to look at the tool diameter?
05:20 PM perry_j1987: i let the gcode run up to where it got near the part and its deff not taking the diameter into account
05:20 PM Tom_L: like i said earlier, i program the tool edge
05:24 PM Tom_L: that's a f360 thing you'll have to figure out but i think you're on the right track not using 'wear'
05:29 PM perry_j1987: i hate stuff like this where you just get slammedi nto a brick wall of no movement forward lol
06:14 PM Unterhaus_: harbor freight finally noticed that there are scam surveys purportedly from them. The big giveaway is that they offer a prize of tools that HF doesn't sell
06:15 PM Unterhaus_: very lazy scammers
06:44 PM roycroft: look at the target demographic
06:44 PM roycroft: they're not expending any more energy than they have to :)
07:23 PM roycroft: well, ups have decided to come late today
07:25 PM roycroft: that means my shop is getting more tidied up than it's been in quite a while
07:28 PM roycroft: oh, jt-shop (or whevever), if you're about or will be in a bit
07:29 PM roycroft: you asked about test cards earlier and doing raster images
07:29 PM roycroft: there are several raster modes in lightburn - greyscale, dither, halftone, newsprint, etc.
07:29 PM roycroft: you might want to do some testing with each mode to see how they look, although i'm not sure you need to do a full test card for each mode
07:32 PM XXCoder: oh yes did you succeed looping exports and imports to get vector image?
08:31 PM roycroft: no, i have not done so yet
08:31 PM roycroft: ups have still not arrived
08:31 PM roycroft: i need a router sled within the next few days to make a countertop for the fair, so i've been working on that
08:32 PM XXCoder: oh boy
08:32 PM roycroft: the .ai file i generated yesterday still is not syncing, and my cad workstation is giving me errors on the sync
08:32 PM roycroft: i haven't had time to get that sorted yet
08:33 PM roycroft: i can sneakernet the file via thumb drive if need be, but i'd rather just fix the problem
09:08 PM Unterhaus__ is now known as Unterhausen
09:10 PM DrewnabobberBCCA is now known as drewnabobber0[m]
10:16 PM roycroft: well ups finally arrived a few minutes ago, and i got all my stuff
10:16 PM roycroft: the origin looks brand new - not a scratch or a mar on it
10:16 PM XXCoder: you got it used right?
10:16 PM roycroft: so i think they actually refurbished it, and didn't just test it and ship it
10:16 PM roycroft: it's refurbished by shaper, and comes with a warrantee
10:17 PM XXCoder: ahh nice
10:17 PM roycroft: it's not going to look brand new for long
10:17 PM XXCoder: I just bought cheap air filters for upcoming smokey hellscope season
10:17 PM roycroft: but i do take pretty good care of my tools, so it won't look like i thrashed on it
10:17 PM roycroft: good plan
10:17 PM XXCoder: lol was about to joke about tool abuse
10:17 PM roycroft: anyway, i need to go finish making dinner
10:18 PM roycroft: i was going to wait until ups arrived, but i finally got hungry and started on it
10:18 PM roycroft: and, of course, ups arrived about 30 seconds later
10:18 PM roycroft: i should have gotten hungry a couple hours earlier :)
10:18 PM XXCoder: should have started dinner sooner so ups gets there earlier lol
10:18 PM XXCoder: lol
10:26 PM roycroft: i'm not going to be able to do anything else with the origin tonight
10:26 PM roycroft: i opened everything, set up the workstation, and scanned the dominos on the workstation
10:27 PM roycroft: but i have to do the os upgrade next, and then figure out how to get my solidworks files to the shaper
10:27 PM roycroft: tomorrow or over the weekend i can do that
10:31 PM XXCoder: nice
10:44 PM roycroft: maybe i'll do the os upgrades tonight, as i have to bring it into the house for that
11:16 PM roycroft: what's interesting is that the origin has no logical connection to the spindle at all
11:16 PM roycroft: the spindle just fits in the sleeve and the power cord plugs in
11:17 PM roycroft: the origin has no clue whether the spindle is present or running
11:17 PM XXCoder: +++
11:17 PM roycroft: when you touch off z, the spindle is lowered, and it senses when the cutter makes contact via a sensor in the base that detects that the base was lifted
11:18 PM roycroft: this is interesting and nice
11:18 PM roycroft: i have operations that will require my switching cutters back and forth several times per part
11:19 PM XXCoder: interesting
11:19 PM roycroft: if i got a spare spindle i could mount both cutters, and switch spindles and touch them off very quickly
11:19 PM roycroft: and i don't really even need a spare spindle on the shelf for that, eventually, as my plan is to get a second origin as a spare when i start doing production work
11:19 PM roycroft: both generation origins use the same spindle, so i could use the spare as my second one
11:27 PM roycroft: anyway, i think i'll be cutting practice parts this weekend, but it will be a while before the thing is actually useful
11:28 PM XXCoder: yeah looked like some skill needed which means test runs and learning
11:28 PM roycroft: yes, it will take a bit
11:28 PM roycroft: fortunately i have a lot of scrap mdf laying around
