04:15 AM JT-Cave: morning
04:35 AM JT-Cave: Tom_L, look at 8:52 https://www.youtube.com/watch?v=4WjXyJTpaW8
05:02 AM Tom_L: morning
05:04 AM Tom_L: that would be pretty easy to do
05:45 AM t4nk_freenode: howdy
05:45 AM * t4nk_freenode watched the entire vid
05:46 AM t4nk_freenode: and dreams of milling metal
05:46 AM t4nk_freenode: :|
05:48 AM * Abanim20[m] uploaded an image: (225KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/VSTmmhkCuLmfBOFoMztuyZiQ/IMG_20220226_161811_454.jpg >
05:49 AM Abanim20[m]: Please how to fix this problem
06:17 AM JT-Cave: ask on the forum in the qtvcp section, a screen shot sucks copy and paste the complete error message
08:28 AM JT-Cave: I really really need to clean up my table down here
09:44 AM unterhausen: I gotta get one of those portable bandsaws.
09:58 AM Tom_L: yep
09:58 AM Tom_L: been lookin and all the corded dewalt are out of stock here
09:59 AM Tom_L: lookin at a milwaukee
09:59 AM Tom_L: keep in mind the blade is separate
10:43 AM roycroft: i still don't have one
10:44 AM roycroft: the main reason i started switching from dewalt to milwaukee for battery tools is because i wanted the milwaukee portaband
10:44 AM roycroft: i've found that i really like the milwaukee tools a lot better than dewalt, but i still haven't gotten the portaband
10:45 AM roycroft: i'm also not doing as much field work as i used to, so it's not as important to have it as it used to be
10:54 AM Tom_L: i don't use em enough to warrant batteries. they would go bad before i got my worth from them
11:02 AM unterhausen: I like milwaukee a little better than dewalt. The prices are comparable on sale. Portabands never seem to go on sale though
11:03 AM unterhausen: I just want the portable because i have no room for a stationary one. Maybe if I got rid of the lathe
11:03 AM unterhausen: lithium batteries don't go bad very quickly. Maybe the off-brand ones, but even those have lasted me years
11:18 AM roycroft: the milwaukee fuel battery portaband is actually more powerful than the corded version
11:19 AM roycroft: when i was doing fiber plant buildouts i used to haul my 4x6 bandsaw in the back of my van to the fiber huts
11:19 AM roycroft: that was a pain in the butt, but once i got my 7x12 and sold the 4x6 it was almost impossible to lug the bandsaw around
11:19 AM roycroft: that's when i started wanting a portaband
11:21 AM roycroft: and as far as battery life, i got my first milwaukee battery tools about 15 years ago, and i've only had one battery die in all that time
11:21 AM roycroft: i have a dozen or 15 batteries total
11:29 AM roycroft: my latest battery tool is one i wasn't sure about - the milwaukee small/trim router
11:30 AM roycroft: it's turned out to be one of my favorite battery tools
11:30 AM roycroft: it works brilliantly, is well balanced, and has relly good extraction
11:30 AM roycroft: i keep a 3/16" roundover cutter set up in it, and use it all the time to ease edges
11:31 AM roycroft: i can even see myself buying one or two more of them
11:31 AM roycroft: as long as they're on sale
12:33 PM unterhausen: I have 2 of the milwaukee trim routers. Really nice not to have to worry about the cord
12:33 PM roycroft: yes
12:34 PM roycroft: although if you use extraction there's the vacuum hose
12:34 PM roycroft: but i haven't found that to be an issue - the extraction hose is usually hanging overhead anyway
12:35 PM roycroft: i'm thinking of three total - one for the roundover cutter that i mentioned earlier, one for a flush trim cutter, and one for whatever random cutter i need at the moment
12:36 PM roycroft: they should be on sale again soon, and i'll probably get another one then
01:20 PM unterhausen: I am thinking there is no place near me that has orings
01:22 PM unterhausen: huh, harbor freight has them and not too expensive. I want to use them to hold a part on the lathe, so HF quality should be fine
01:24 PM unterhausen: If you don't want to buy something, google can be pretty useless. They should have a checkbox for "I am not buying, I'm making"
01:25 PM roycroft: i've bought the us customer and metric o-ring sets from hf
01:25 PM roycroft: they seem to work well
01:25 PM XXCoder: yeah google can be annoying on that sometimes :(
01:26 PM unterhausen: only thing for mandrels is you want the OD and orings are sized by id
01:28 PM Tom_L: there is an O-ring shop here.. that's about all they sell :)
01:41 PM roycroft: o-rings-r-us?
01:47 PM Tom_L: i forget their name but i know where they are
01:51 PM unterhausen: yeah, I assume I can get some at various places in town, but an assortment will be nice
01:51 PM unterhausen: the local industrial supply is gone, unfortunately
01:51 PM unterhausen: it was on a back street in a house, so it's not surprising that nobody knew about them
01:52 PM unterhausen: anyone ever try using a harbor freight coupon on their phone? Maybe I should just print it
01:53 PM unterhausen: lcnc is now on debian, congrats to everyone that made that happen
02:03 PM roycroft: that's good, in a way
02:03 PM roycroft: it makes it more accessible
02:04 PM roycroft: but the debian package is likely not going to be up to date very often
02:04 PM roycroft: perhaps that's not a big deal - my impression is that a lot of folks here run older versions of linuxcnc
02:25 PM JT-Shop: found the panasonic servo drive communications cable only 2 left to get/find
02:37 PM unterhausen: I think having a lcnc version that's a little stale is just fine. Functionality keeps being added, but it's usually for edge cases
02:37 PM unterhausen: people are still running emc/emc2
02:42 PM roycroft: i wonder if the debian package installs a rtk
02:43 PM roycroft: i'll have to give it a go in a vm to see what it installes
02:45 PM XXCoder: roy yeah not a huge deal, less updates but very stable is best for lcnc
02:50 PM JT-Shop: found an encoder cable for $118
02:51 PM roycroft: as long as it's somewhat recent
02:51 PM roycroft: a lot of debian packages are ancient
02:52 PM roycroft: and even for linuxcnc, ancient should not be that big of a deal, but my impression is that a lot of users connect their linuxcnc machine to the internet, and that's rather concerning
02:52 PM roycroft: and a good argument for keeping the machine up-to-date
03:23 PM pere: Is Ethercad going to get into official linuxcnc any time soon, ref <URL: https://invidious.snopyta.org/watch?v=NQ-HnrusGJo >?
03:36 PM * roycroft experiences a moment of déjà vu
03:37 PM XXCoder: sadly that site dont have captions so not sure what its talking about
03:53 PM roguish[m]: good afternoon. does anyone know if and where old .deb files are kept, older than what is shown on the /dists/buster/master-rtpreempt directory ????
04:05 PM roguish[m]: shit howdy. found them on my computer.. /var/cache/apt/archives
04:05 PM Tom_L: that's one good hiding place
04:06 PM roguish[m]: the power of 'find'
04:07 PM Tom_L: http://buildbot.linuxcnc.org/dists/
04:07 PM Tom_L: may go back to 2.6
04:08 PM Tom_L: pretty sure buster came in around 2.7
04:12 PM roguish[m]: naw, check under buster/master
04:12 PM roguish[m]: doesn't go back very far
04:19 PM Centurion_Dan1 is now known as Centurion_Dan
04:30 PM JT-Shop: I wish debian didn't use those stupid names and just use the number
04:30 PM roguish[m]: totally agree,,,,
04:34 PM JT-Shop: just figured out my panasonic servo and drive is 400w with incremental encoder
04:41 PM JT-Shop: 2 more and I have a 3 axis CNC something
04:43 PM Tom_L: what kind of something do you not have yet?
04:43 PM JT-Shop: router
04:43 PM Tom_L: well then
04:43 PM JT-Shop: I have a bunch of linear rails and trucks some maybe too big for that, have to inventory
04:44 PM JT-Shop: ballscrews on amazon must be real crap they are cheap
04:47 PM roycroft: but still better than threaded rod, and better than probably most acme screws
04:53 PM JT-Shop: but first I want to test my configuration tools with a servo to make sure everything is working as it should
04:53 PM XXCoder: JT look for C7 rating in least
04:53 PM XXCoder: if it does not have C rating, its utter crap
04:54 PM roguish[m]: JT-Shop: do you need motors or drives or both
04:54 PM XXCoder: C7 costs barely more than unrated costs, but in least it should have been tested.
05:02 PM JT-Shop: I have one 400w drive and motor now
05:06 PM roguish[m]: I have a couple sets of yaskawa
05:06 PM roguish[m]: yaskawa that I could part with
05:08 PM roguish[m]: what power do you need?
05:11 PM JT-Shop: I'm not sure, what power is the yaskawa's?
05:13 PM roguish[m]: some 200w and some 400 w
05:14 PM JT-Shop: I'm guessing at least 2 400w and for the Z a 200w are they 120vac?
05:14 PM roguish[m]: i would have to dig around and check the inventory.....
05:15 PM JT-Shop: ok
05:15 PM roguish[m]: ]could be 220
05:15 PM * JT-Shop has been checking his inventory
05:48 PM roycroft: and for the second sunday in a row, this has happened
05:49 PM roycroft: rockler send me an email encouraging me to buy some cord winding brackets 'while they are still available"
05:49 PM roycroft: then a minute or so later rockler send me an email telling me that the cord winding brackets that i ordered in january are still on back order, and will be delayed even further
05:51 PM JT-Shop: roguish[m], are the yaskawa AC servos?
06:10 PM pcw--home: JT-Shop: A Yawskawa drive is an AC servo unless it is very ancient
06:10 PM JT-Shop: thanks
06:10 PM JT-Shop: hows the 7i96 conversion coming along?
06:16 PM JT-Shop: I'm making good progress on my configuration tools, I think the 7i92 is ready
06:39 PM CaptHindsight[m]: https://www.youtube.com/watch?v=0XaaUXOwzTs
06:42 PM roguish[m]: pcw--home: hey Peter, how are ya?
06:44 PM roguish[m]: JT-Shop: pcw--home yes. the yaskawas are AC servo. these are old, but pretty good
06:46 PM roguish[m]: pcw--home: tuning question. would doubling encoder ppr help in pid tuning of an axis?
06:48 PM CaptHindsight[m]: yaskawa drives with USB ports are still pretty easy to configure
06:48 PM Tom_L: roguish[m], you would get more samples per period
06:49 PM CaptHindsight[m]: I have an older one with serial and so far no luck with the old DOS tools
06:52 PM roguish[m]: Tom_L: yes, i know that. just not sure if it would markedly improve the tuning and consequently reduce the f-error.
08:09 PM _unreal_: what a pain in the assssss that was
08:09 PM _unreal_: regardless just finished fixing a free high power fan I got
08:09 PM _unreal_: got a TD-250/100
08:11 PM _unreal_: https://ae01.alicdn.com/kf/HTB1Qdo8CNSYBuNjSspjq6x73VXab/4-inch-booster-fan-plastic-ventilation-pipe-exhaust-ceiling-fan-for-bathroom-kitchen-air-vent-inline.jpg
08:14 PM _unreal_: this is the version I have https://www.supplyhouse.com/SP-TD-125-TD-MIXVENT-5-Mixed-Flow-Duct-Fan-120V-2146-RPM-38W
08:16 PM _unreal_: its more or less 200 CFM
08:17 PM _unreal_: not sure how to read the air pressure but regardless i'm planning on turning it into the dust collector blower for the new cnc machine
08:18 PM _unreal_: its like 3x the power of the blower I'm using on the mini cnc machine
08:18 PM _unreal_: for dust collection and that works the bomb
08:32 PM _unreal_: just did a power test.... :/
08:32 PM _unreal_: not very powerful
09:34 PM pcw---home: roguish[m] changing the encoder resolution is not likely to make much difference unless its really low
09:36 PM pcw---home: JT-Shop Still waiting for proto PCBs (ordered over Chinese new year)
10:02 PM unterhausen: I can't even access my photobucket account because there are external links to it
10:02 PM unterhausen: so I asked them to deleted it
10:02 PM unterhausen: that was actually the only two things offered, upgrade or delete
10:14 PM unterhausen: okay, downloaded my pics, now I'm going to delete everything
10:16 PM Tom_L: google says it can find it for you
