12:00 AM perry_j1987: 48v
12:06 AM _unreal_: or how ever you spell it
12:06 AM _unreal_: 48v and depending on size its prob 4-8 amps output
12:06 AM perry_j1987: LEDs on the front panel show 48v,24v,12v,5v
12:06 AM _unreal_: how many wires comming out of the transformer
12:06 AM _unreal_: might be worth trying to find the controller card FYI
12:06 AM _unreal_: how many wires comming out of the transformer
12:06 AM _unreal_: 2 wires in MAINs, X wires coming out secondaries
12:06 AM _unreal_: can be even or odd numbers
12:06 AM _unreal_: and different wire thickness
12:06 AM _unreal_: thinner wires LOWER voltage
12:06 AM _unreal_: normally
12:06 AM perry_j1987: http://support.technocnc.com/pdf/0229_LC_and_Lathe_Board-Callouts-Connectors.pdf
12:06 AM perry_j1987: guessing 4
12:08 AM perry_j1987: the guys who made these lathes spun off and are now armorcnc.com
12:08 AM perry_j1987: i might be able to find someone there who has more info
12:08 AM _unreal_: is the company that built it still alive?
12:09 AM perry_j1987: they split
12:09 AM perry_j1987: techno isel is still around
12:09 AM perry_j1987: but the guys who desgned and built the lathes are now armorcnc
12:09 AM _unreal_: I'd contact them
12:10 AM _unreal_: who know's maybe you can find he controller OR even get more specs
12:10 AM _unreal_: the other option is to probe those pins. trace the I/O's from JP2 which I assume goes to a PC
12:10 AM _unreal_: and see what chips are connected to them
12:10 AM _unreal_: if they are 5V chips. then HELL
12:11 AM _unreal_: wire everything up and probe 5v to the pins SEE what happens
12:11 AM _unreal_: JP2 you got a bank of logic chips just below it
12:11 AM _unreal_: trace the pins and see if the chips you can identify. if you CANT...
12:12 AM _unreal_: find out what there specs are
12:13 AM perry_j1987: if i remember right i seen a bunch of 74HC chips all over this board
12:13 AM _unreal_: JP6 is prob something like BUTTONS maybe an MPG. or DRO?
12:13 AM _unreal_: thats 5v
12:13 AM perry_j1987: aye
12:14 AM perry_j1987: there's no hookups or blank panel spots on the chassis for other options
12:14 AM _unreal_: so no jp6
12:14 AM _unreal_: is there JP2 or jp4 on your board?
12:14 AM perry_j1987: appears it was only software controlled through jp2
12:14 AM perry_j1987: jp2 is populated thats got cord plugged into it
12:15 AM perry_j1987: jp4 and p6 and those chips around it are not populated
12:15 AM _unreal_: so you got the cheap shitty one lol
12:16 AM perry_j1987: this board is used in the lathes and also their routers
12:16 AM perry_j1987: the lathes dont need as much stuff
12:16 AM _unreal_: if its the same board. then again maybe you can find the control card
12:16 AM _unreal_: regardless
12:17 AM _unreal_: that also narrows down shit
12:17 AM _unreal_: how many pins on JP2
12:17 AM _unreal_: is it a PAR port db25?
12:17 AM _unreal_: DB34?
12:17 AM _unreal_: some funky blade like insert?
12:18 AM perry_j1987: looked like scsi cable or somethin
12:19 AM perry_j1987: https://www.armorcnc.com/pciupgrade
12:19 AM perry_j1987: spendy heh
12:19 AM _unreal_: http://support.technocnc.com/Controller_mainboard.htm
12:21 AM _unreal_: http://support.technocnc.com/PCI400_Card_pinout.htm
12:22 AM perry_j1987: thats for diff board but i wonder... if the pinout is similar heh
12:23 AM _unreal_: the pinout is likely the same
12:23 AM _unreal_: the if its the same header
12:23 AM perry_j1987: should be easy to probe and test the limit switches for some validity
12:23 AM _unreal_: and if its all 5v you could use most any mesa card to drive it I DO question the ANALOG input though
12:25 AM _unreal_: andthe A1 -A1 B1 -B1, L1 -L1, A2 -A2 B2 -B2 .... ARE LIKELY for stepper control
12:25 AM _unreal_: I dont know what the L is enable maby
12:26 AM _unreal_: the letters, or the analog could drive servos
12:26 AM perry_j1987: by what means?
12:28 AM perry_j1987: there's big warning on the main screen
12:28 AM perry_j1987: prob diff pinout
12:28 AM perry_j1987: it warns to make sure you match the pci card with the board
12:31 AM _unreal_: ?
12:31 AM _unreal_: https://www.aliexpress.com/item/32957418177.html?spm=a2g0o.productlist.0.0.5ced6ba5Ftf2oq&algo_pvid=d76cef1c-3c32-4265-8155-1f0e023c4905&algo_expid=d76cef1c-3c32-4265-8155-1f0e023c4905-0&btsid=0b0a556016097411395846324e1017&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
12:31 AM _unreal_: found one
12:31 AM perry_j1987: aye there on ebay as well
12:32 AM _unreal_: so up to you.
12:32 AM _unreal_: but I dont know what the software is that makes it work
12:33 AM _unreal_: :S
12:33 AM _unreal_: 1:30am I have to work and be up early
12:33 AM _unreal_: I have not seen any on egay
12:33 AM _unreal_: but they ARE out there
12:33 AM _unreal_: I guess the real question is WHAT software do they use. what do the cards cost.
12:34 AM _unreal_: what is the accuracy of the current hardware
12:34 AM _unreal_: features ablity, as is and with the software that makes that card work.
12:35 AM _unreal_: does it read gcode? does it read its own system only?
12:35 AM perry_j1987: i def dont want to put together the stock system
12:36 AM _unreal_: if it proves to be a modern antique then go with new drivers G320x'S ETC... and upgrade
12:36 AM perry_j1987: aye
12:36 AM _unreal_: well the question is does the stock controller function and can you interface it
12:36 AM perry_j1987: question being, stick with this toroid and add some recitfiers and caps or go switching
12:36 AM _unreal_: if its all 5v...
12:36 AM _unreal_: well that controller its self could be usable
12:37 AM _unreal_: I would suggest at least probing it out and figuring out what its input power is.
12:37 AM _unreal_: if its a throw away then you dont care anyways
12:37 AM _unreal_: maybe setup a safty POWER kill and start doing some 5v wire probing on the logic input
12:37 AM perry_j1987: apparently i can sell the board for 400 or so
12:37 AM _unreal_: HUM
12:38 AM _unreal_: up grade for a discount
12:38 AM _unreal_: never even thought about that BUT you dont know if it works
12:38 AM _unreal_: or do you
12:38 AM _unreal_: o,O O,o o,O
12:38 AM perry_j1987: i have no idea
12:38 AM perry_j1987: its assumed to be working
12:39 AM perry_j1987: machine itself looks like it has low useage all in all
12:39 AM _unreal_: then flip a coin... sell the controller board maybe make a buck. prob it out risk bricking the unknown or maybe discover how to operate it and use a mesa to just drive it
12:39 AM perry_j1987: so couple g320x drivers and what a 48v switching psu?
12:40 AM _unreal_: I dont kno wwhat g320's support for voltage
12:40 AM perry_j1987: up to 80
12:40 AM _unreal_: ok
12:41 AM _unreal_: from what I saw the transformer has no N wire (middle) so its just left/right
12:41 AM _unreal_: just means no negative voltage
12:41 AM _unreal_: just +/-
12:41 AM _unreal_: after diodes
12:42 AM _unreal_: so your going to want a 25amp bridge with heat sink
12:42 AM _unreal_: and with out knowning the specs of the transformer picking caps can be fun
12:43 AM perry_j1987: i'd have to scope it
12:43 AM _unreal_: maybe 20,000f cap(s)
12:43 AM perry_j1987: or well could just read the cap on the board thats existing lol
12:44 AM _unreal_: cheater
12:44 AM perry_j1987: lol
12:44 AM perry_j1987: any reason to go with toroid vs switching psu?
12:44 AM _unreal_: I bet its 10,000uF
12:45 AM _unreal_: the main difference is is that you can heat the transformer till the coating on the coils melts
12:46 AM _unreal_: a switcher will give you near endless PERFECT output but is brittle compaired to a transformer.
12:46 AM _unreal_: a transformer the voltage can float up/down a lot 4-10v easy on the output
12:47 AM _unreal_: and if you have a brown out or a massive voltage spike with out protection. the transformer is blind its just a coil of wire
12:47 AM perry_j1987: what do you mean
12:47 AM _unreal_: so advanced motor controllers are not going to care about the voltage spike to much
12:47 AM _unreal_: I mean exactly what I said
12:48 AM _unreal_: a transformer will not give you constant exact voltage output. but its HARTY, a switching PSU wil give you a perfect or near perfect output of voltage current but its brittle meaning they can over heat they can thermal shut down. ETC...
12:48 AM _unreal_: A transformer works till it melts
12:48 AM _unreal_: clear enough?
12:48 AM perry_j1987: aye
12:49 AM _unreal_: remember a transformer, its input voltage is relative to its output voltage. just stepped up/down/1:1-isolation
12:49 AM perry_j1987: so rectified voltage feeding servo drivers, then rectified then regulated voltage for 5v line
12:50 AM _unreal_: the lower secondary line is your electronics power
12:51 AM _unreal_: so thats 24v for relays, and reduced with voltage regulators for lower voltages 9v, 5v etc.....
12:52 AM _unreal_: I would turn the 24v (18vac) into 24v dc, 12v dc, 5vdc. and I would use DC-DC buck converters as drivers
12:53 AM _unreal_: if the diode bridge gets hot thats normal. IF the transformer gets stupid hot. its being over drawn
12:53 AM _unreal_: if the bridge gets burning hot its being over drawn.
12:53 AM _unreal_: you dont want to drive more then 50% of the rated value on a bridge if possible
12:54 AM perry_j1987: 50amp rectifiers are dirt cheap
12:54 AM _unreal_: yes they are
12:54 AM _unreal_: but they still need a heat sink
12:54 AM perry_j1987: aye
12:55 AM _unreal_: be it a FINNED heat sink or be they bolted with compound to a surface
12:55 AM _unreal_: ok going to bed
12:55 AM _unreal_: I'm sure I've fed you enough data to keep ya busy
12:55 AM _unreal_: :
12:55 AM _unreal_: :)
12:56 AM perry_j1987: guess i'll get the g320x drivers ordered
12:57 AM _unreal_: your call
12:57 AM _unreal_: LOL democrates are freaking out how
01:02 AM Deejay: moin
02:32 AM veegee_: I put quick couplers on the implements on my forklifts so I can use one forklift's pump to power the hydraulics on another
02:32 AM veegee_: So now I essentially have multiple mobile hydraulic power units
02:33 AM veegee_: Welded some cylinders to the super heavy machines so they can easily be raised/lowered on their own. No need for special toe jacks or anything like that
02:34 AM veegee_: Hydraulically extended casters to move them, then retract when in place
02:34 AM veegee_: What a weird hobby
02:36 AM XXCoder: careful or turn into forklift shop ;)
02:38 AM XXCoder: might be not bad if area really needs one
04:49 AM JT-Cave: morning
04:49 AM XXCoder: good morning sir JT-Cave
05:09 AM JT-Cave: what's up this morning
05:12 AM XXCoder: not a lot
05:50 AM JT-Cave: you still on the night shift?
05:51 AM XXCoder: im still on no shift ;)
05:52 AM JT-Cave: sleep wise
05:52 AM XXCoder: oh lol yeah
06:14 AM Tom_L: morning
06:17 AM JT-Cave: yo
06:17 AM JT-Cave: https://jethornton.github.io/stdeb/console.html
06:17 AM JT-Cave: almost done
06:18 AM XXCoder: might want to hide certain info
06:18 AM JT-Cave: kinda thought about that too
06:18 AM XXCoder: just change it to fake one
06:22 AM JT-Cave: looked at the clock and thought I was late but I have 50 minutes until chicken time
06:23 AM JT-Cave: refresh travis is done building
06:30 AM Tom_L: nice one
06:30 AM XXCoder: hey tom
06:31 AM Tom_L: i assume that structure goes in the useer dir
06:34 AM JT-Cave: not sure what you mean???
06:34 AM Tom_L: Start by creating a directory structure with the following empty files.
06:34 AM JT-Cave: not sure where to start?
06:35 AM Tom_L: do you put that directory structure in the user dir?
06:36 AM JT-Cave: what is the user dir?
06:36 AM Tom_L: /home/john
06:36 AM JT-Cave: yes or anywhere under /home/john
06:37 AM Tom_L: i'll try it afterwhile
06:38 AM JT-Cave: I'll clarify the location
07:43 AM jymmmm: Morning
08:34 AM gregcnc: perry_j1987 that communication pinout looks interesting
08:43 AM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20210104_074520.jpg
08:43 AM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20210104_074444.jpg
08:46 AM gregcnc: has a shoulder like a lathe?
08:50 AM skunkworks: yes
08:55 AM gregcnc: should be much more accurate that just the thread, register is guess is the correct term
08:55 AM skunkworks: yes - I am going to make a small touch probe that mounts that way
08:56 AM skunkworks: (not out of plastic)
08:56 AM skunkworks: it will be a low profile as I can get it.
08:57 AM gregcnc: without a holder, it will be short
09:35 AM perry_j1987: morning
09:35 AM perry_j1987: gregcnc ya?
09:35 AM perry_j1987: that one was for a diff board/pci combo they made but what are odds its similar pinout
09:36 AM perry_j1987: though there was a warning on the page saying to make sure you match the pci card with the board or damage may occur so that sounds like they are diff pinouts
09:42 AM gregcnc: A1,B1, I1 are encoder signals
09:45 AM gregcnc: techno isle are pretty common i'm surprised people haven't looked into these closely
09:50 AM perry_j1987: so they are passing encoders straight to their pci card/control software
09:50 AM perry_j1987: i did order two g320x last night
09:55 AM perry_j1987: just called armorcnc
09:55 AM perry_j1987: asked for pinout and she said she thinks they have that document and passed my info to one of their engineers to email that to me
10:00 AM perry_j1987: i gotta run errands
10:00 AM perry_j1987: bb later
11:42 AM gregcnc: are any sealants better for coolant tanks/enclosures than others?
11:46 AM Tom_L: can't weld it?
11:47 AM Tom_L: lcvette had one he tried to seal, you might ask him what he did if you can find him
11:47 AM Tom_L: epoxy maybe?
11:47 AM gregcnc: There are dividers I want to seal off. so i don't have to put 20-30 gallons in
11:47 AM Tom_L: dunno how well silicone would hold up
11:48 AM Tom_L: no matter what, you want it clean beforehand
11:48 AM gregcnc: right
11:49 AM Tom_L: https://www.practicalmachinist.com/vb/cnc-machining/30-gallons-coolant-floor-sealant-recommendations-211515/
11:49 AM Tom_L: aparently rtv doesn't work
11:50 AM Tom_L: what about solder? that was a suggestion there
11:50 AM gregcnc: it's painted
11:50 AM Tom_L: Permatex's "The Right Stuff" holds up very well in coolant. NAPA and other auto stores carry it.
11:50 AM Tom_L: dunno...
11:51 AM gregcnc: I have a tube. I should have tried sample by now.
12:02 PM Rab: My go-to for sealing/adhering in harsh conditions is Permatex Ultra Black, which the big box stores carry. I haven't tried The Right Stuff.
12:03 PM roycroft: fwiw, permatex blue is what the air-cooled vw folks have always used to seal the crankcase halves together - it's pretty tough stuff
12:04 PM roycroft: well, i shouldn't say always, but at least since i started working on vws in the late '70s
12:09 PM roycroft: i'm not sure what the difference is between the products, but ultra blue stipulates that it can be used for import engines, and ultra black does not
12:12 PM Tom_L: the blue stuff doesn't adhere that well in 'oily' conditions
12:12 PM Tom_L: but i have sealed a many vw case with it
12:14 PM roycroft: perhaps it does not adhere if the surface is oily, but once cured it's quite oil-resistant
12:15 PM roycroft: the ultra black specs talk about drivetrain applications
12:15 PM unterhaus_: people have been passing around the schematic of a guitar effects pedal saying it is in the covid vaccine
12:15 PM unterhaus_: Boss Metal Zone, widely regarded as one of the worst guitar pedals ever
12:15 PM roycroft: and that could have to do with adhesion in an oily environment
12:15 PM roycroft: the heavier oils used in the drivetrain are more difficult to completely remove from the surface then the lighter engine oil
12:19 PM unterhaus_: trying to remember what I learned about sealing coolant. But I think it was just "don't use silicone sealants"
12:20 PM roycroft: i suppose that would depend on the type of coolant
12:24 PM gregcnc: ah, Ultra Blue or Ultra Copper is recommended by Cimcool
12:24 PM gregcnc: and say to avoid white or clear silicone
12:28 PM Tom_L: wonder what gorilla tape would do
12:29 PM gregcnc: another place a guy ordered sealant from fadal and got sikaflex 1A
12:30 PM roycroft: i am confused
12:31 PM roycroft: i was wondering why the vw folks use ultra blue instead of ultra black to seal their crankcases, but then figured, having been in the air-cooled vw community for decades, that ultra blue was 3 cents cheaper than ultra black
12:31 PM roycroft: to verify, i checked online, and to my astonishment found that ultra blue is actually more expensive than ultra black
12:31 PM Tom_L: :) no confusion there
12:32 PM Tom_L: but was it back then?
12:32 PM roycroft: that i don't know
12:32 PM Tom_L: i know we used it
12:32 PM roycroft: i've known a heck of a lot of ac vw engine rebuilders, and every single one of them uses ultra blue
12:33 PM Tom_L: i've rebuilt dozens in a previous life
12:33 PM gregcnc: i'll need more than a small tube, more like a caulk tube worth. will see how sika does. it won't spill, just won't help with what i'm doing if it leaks
12:33 PM roycroft: the sensor safe ultra blue is even more expensive
12:33 PM JT-Cave: office depot closed and no one carries the Adams AFR10W Vehicle Mileage Log
12:33 PM roycroft: but the only sensors that air-cooled vw folks use are their noses
12:34 PM roycroft: i hven't picked up my vehicle log books for the year yet
12:34 PM roycroft: that's on my list to do today or tomorrow
12:34 PM roycroft: we used to have two office maxes, two staples, and three office depots
12:34 PM Tom_L: https://www.officedepot.com/a/products/483272/Adams-Vehicle-Mileage-Book-3-14/
12:34 PM roycroft: now we have one office depot
12:35 PM roycroft: the local stationary stores are long gone
12:35 PM Tom_L: JT-Cave, i just keep a pocket notebook in the car door
12:36 PM roycroft: one of them converted to a bird feeder store
12:36 PM roycroft: then a piano store
12:36 PM JT-Cave: I may start doing that
12:36 PM roycroft: now the building is vacant
12:40 PM roycroft: oh thank goodness
12:41 PM roycroft: my new mbp has shipped
12:41 PM roycroft: and it is scheduled to arrive on wednesday
12:41 PM roycroft: my current one crashes every 10 minutes or so
12:41 PM roycroft: and the linux laptop i built is just not working out well enough for me to be efficient using it
12:42 PM roycroft: it's getting better, but it's not there yet
12:58 PM veegee_: https://www.kijiji.ca/v-other-business-industrial/city-of-toronto/heavy-ass-welding-table/1541458298
01:13 PM roycroft: excellent
01:13 PM roycroft: my doctor just called, and confirmed that i qualify as high risk, and may have news later today on when i can get a vaccine
01:14 PM roycroft: which she is thinking could be within the next week or two
01:19 PM JT-Shop: what makes a person high risk besides old age?
01:21 PM FinboySlick: I think heart condition is one of them.
01:22 PM FinboySlick: (at least around here)
01:22 PM roycroft: i have lung scarring from pneumonia
01:22 PM FinboySlick: Yeah, that'll do it too.
01:22 PM roycroft: the other things that i know of are:
01:22 PM roycroft: over 65
01:22 PM roycroft: diabetes
01:22 PM roycroft: high blood pressure
01:23 PM roycroft: there are probably other factors that qualify
01:25 PM roycroft: all i know is that i'm ready to get poked in the arm
01:25 PM JT-Shop: yeah I'd guess any lung issues move a person to the top of the line like COPD
01:27 PM roycroft: i'm a little concerned about this half dose idea that's come up
01:27 PM roycroft: but my reading says it would only apply to people between 18 and 55
01:27 PM roycroft: i'm old enough that i'd still get the full dose
01:36 PM roycroft: the cdc say that full immunity is not reached until two weeks after the second shot
01:37 PM roycroft: so realistically march 1 would be the sooned i would expect that, if things go well
01:41 PM veegee_: you'll have fun with the interferon induced symptoms
01:43 PM roycroft: 8649
01:44 PM roycroft: ack, mispaste
01:44 PM Tom_L: your cc pin?
01:44 PM skunkworks: I was thinking bank account login..
01:46 PM roycroft: i would not have pin numbers/passwords that short
01:46 PM roycroft: nor would i cut and paste them
01:47 PM roycroft: it's part of a phone number, actually
01:47 PM roycroft: i'm auditing our sip trunks
01:48 PM unterhaus_: my phone number used to be a couple digits off of 867 5309
01:48 PM unterhaus_: I don't exactly remember it, because i only used it to dial out
01:48 PM roycroft: 8649 spells unix on a phone keypad
01:49 PM roycroft: so i have a rather unique thing
01:49 PM roycroft: a half sheet of 11/16" mdf
01:49 PM skunkworks: Ugh.. Sip testing happening here on friday..
01:49 PM roycroft: a thickness that is not manufactured
01:49 PM Tom_L: skunkworks, what was the red cap for?
01:49 PM roycroft: it started out as a sheet of 5/8" mdf
01:50 PM skunkworks: Tom_L: I want to make a touch probe.. Just me playing with freecad and 3d printing
01:50 PM roycroft: but it's been sitting in my lean-to shed for a couple years, and with our 110% relative humidity in the winter, it's put on some girth
01:51 PM Tom_L: skunkworks, will be interesting what design you end up with
01:51 PM skunkworks: it will probably be 6 ball 3 rod type.
01:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/emc/small_probe4.jpg
01:52 PM roycroft: i have gone back and forth on getting a touch probe for my 3d printer, but i'm leaning towards not bothering

01:52 PM roycroft: i use a piece of tempered glass as my build bed, and it's very flat
01:52 PM skunkworks: Tom_L: cool - how does it work for you?
01:52 PM Tom_L: i never use it :)
01:53 PM roycroft: i check the bed level whenever i change filament spools, which is not often
01:53 PM roycroft: and it's never off
01:53 PM Tom_L: at the time i didn't have a good way to get the pins divided evenly so it was off a tiny bit
01:53 PM skunkworks: Tom_L: I can't live without the probes we have for the K&T and matsuura.
01:54 PM Tom_L: i generally reference things from a vise corner etc

01:54 PM JT-Shop: damn spammers keep sending me crap to whateverIcallIt@spyderstore.com
01:55 PM Tom_L: those could have been done better
01:55 PM gregcnc: some shops probe everything
01:55 PM Tom_L: they do where my kid works
01:56 PM gregcnc: can prevent a lot of problems with stock and locate subsequent ops for better precision
02:00 PM Tom_L: skunkworks, i needed the probe IO for something else
02:02 PM Tom_L: if you make one, this is a good source for tips: https://www.carbideprobes.com/
03:24 PM -!- #linuxcnc mode set to +v by ChanServ
03:42 PM perry_j1987: gregcnc got email back from the company, the jp4 is pci bus connection he said
03:43 PM gregcnc: well, at some point you just have to decide how to proceed
03:45 PM perry_j1987: they offered to buy the board from me
03:45 PM perry_j1987: heh
03:48 PM perry_j1987: gregcnc do you think i should use the toroid and add some bridge rectifiers / caps or get switching psu brick
03:51 PM Tom_L: i went with a linear supply but switchers are quite popular now
03:51 PM gregcnc: Either way. I use switchers. A 200W a 48V psu is not expensive
03:51 PM Tom_L: i had them is why though
03:52 PM perry_j1987: think i'll just need 48v and 5v
03:52 PM perry_j1987: case fan is 120v
03:52 PM Tom_L: and 10 if you need an analog ref for spindle control
03:52 PM Tom_L: or +-10
03:53 PM perry_j1987: the BOB scrounges that up from somethin
03:57 PM perry_j1987: this is going to be insane having a lathe that holds repeatability lol
03:57 PM perry_j1987: really looking forward to this
03:58 PM gregcnc: you ordered the Gecko, did you figure out if the encoders are suitable?
03:58 PM gregcnc: or gettign encoders also?
03:58 PM perry_j1987: i was told they were
04:00 PM perry_j1987: just got email from the mfg of this lathe they said toroid psus are much better for servos than switching psus.
04:01 PM gregcnc: yeah I also read that when I started
04:02 PM Tom_L: and ignored it?
04:02 PM gregcnc: couldn't find anything explaining why
04:02 PM unterhaus_: might be a little better
04:02 PM Tom_L: by now smps should be as good as linear
04:02 PM gregcnc: I think it has to do with regen on braking
04:03 PM unterhaus_: smps much easier to lift for the same power
04:03 PM Tom_L: gregcnc, possibly digital noise
04:03 PM gregcnc: maybe with crap PSU
04:04 PM unterhaus_: I bought some servo drives with built-in linear psu and they were incredibly big
04:04 PM unterhaus_: didn't really know what I was doing back then, quickly learned
04:04 PM gregcnc: regen could push the voltage high, and depending on the PSU design different things can happen
04:05 PM unterhaus_: it could blow the filter caps on any psu
04:05 PM perry_j1987: could use zener to cap the voltage for your drivers?
04:05 PM gregcnc: if rapid and accel is high, may have to do someting
04:05 PM gregcnc: https://www.geckodrive.com/support/returned-energy-dump.html
04:07 PM gregcnc: I have a shunt regulator from AMC for one fo the machines I think. The other has never had anything, but isn't fast either
04:17 PM perry_j1987: be back later
04:34 PM _unreal_: hello
04:52 PM * JT-Shop needs to clean his desk off...
04:54 PM _unreal_: I've been telling my self I need to think about making a plan of action and time to think about thinking about doing just that
05:04 PM Thorhian: Well good news people, I reseated all of the cabling and replaced the power cable to my stepper driver and everything seems to be running properly now.
05:05 PM XXCoder: nice
05:05 PM XXCoder: https://www.reddit.com/r/interestingasfuck/comments/kq6f9v/magnetically_assisted_gears/
05:05 PM XXCoder: cool but not for machining
05:11 PM gloops: good to hear it Thorhian
05:53 PM JT-Cave: made a dumb mistake in my ladder not waiting for a few seconds on bootup before sending the init commands to the drive
05:54 PM JT-Cave: I should have known better after 30 years of programming plc's
05:55 PM XXCoder: tsk tsk bad boyu
05:55 PM XXCoder: ;)
05:55 PM XXCoder: thats why its in testing phase and not at site-production already right? :)
05:57 PM JT-Cave: yeah, I didn't run into it here because I was changing the program so much but at the range when I powered both the drive and plc up at the same time the drive was not ready to receive the init commands when the plc sent them
06:01 PM XXCoder: oops
06:02 PM Tom_L: blow anything?
06:02 PM JT-Cave: no, just went at a snails pace to the commanded position lol
06:02 PM Tom_L: could have been worse
06:02 PM JT-Cave: yeah
06:03 PM JT-Cave: no accel, decel, vel and we go sloooooow
06:03 PM Tom_L: still need to test your deb build...
06:03 PM JT-Cave: just about done with the gui deb tutorial
06:03 PM Tom_L: i noticed you added a menu item for it
06:04 PM Tom_L: is there a way to separate what is deb and what is menu?
06:04 PM JT-Cave: yea it puts it in the menu when you install it
06:04 PM Tom_L: i can't seem to find my deb build directions here
06:04 PM Tom_L: probably on a drive i wrote over...
06:04 PM JT-Cave: yeah the .desktop file is what gets placed in the menu
06:05 PM Tom_L: ie kernel debs don't get a menu item :)
06:05 PM JT-Cave: data_files = [('share/applications/', ['Console DEB.desktop'])],
06:05 PM JT-Cave: leave that line out
06:05 PM JT-Cave: kernel debs prob don't have an entry point either
06:06 PM CaptHindsight: JT-Cave: which PLC's do you prefer these days?
06:07 PM JT-Cave: usually Automation Direct Click unless it needs high speed outputs then a BRX is used
06:08 PM JT-Cave: the Click now has high speed inputs which is nice
06:11 PM CaptHindsight: ah CLICK PLC Software & Cables $11.00, just like AB :) not
06:12 PM JT-Cave: I have a briefcase full of AB cables lol
06:19 PM * JT-Cave wanders upstairs for some chow
07:45 PM flyback: https://www.youtube.com/watch?v=9el1GI4gUxk
08:22 PM Tom_dev: JT-Cave, ModuleNotFoundError: No module named 'setuptools'
08:25 PM Tom_dev: python-setuptools 40.8.0-1 installed
08:27 PM Tom_dev: adding python3-setuptools 40.8.0-1
08:27 PM Tom_L: not included on a default debian install aparently
08:29 PM Tom_dev: error: invalid command 'bdist_deb'
08:33 PM Tom_dev: also i have no __init__.py file
08:50 PM perry_j1987: back
08:50 PM perry_j1987: hows it going
08:54 PM perry_j1987: gah all comfortable in recliner for first time of the day and forget glasses across the house heh
09:32 PM skunkworks: I don't get comfortable... Other wise I fall asleep
09:34 PM perry_j1987: heh
09:34 PM _unreal_: about time you got back
09:37 PM perry_j1987: working on building on a new room out at the shop
09:37 PM perry_j1987: for the new lathe to go in heh
10:02 PM _unreal_: so have you settled on your choice of lathe fututre and direction?
10:15 PM mrec: _unreal_: did you ever cut acrylic?
10:21 PM mrec: I wonder what might be better single flute up or single flute downcutting for it
10:21 PM mrec: especially for acrylic sheet
10:38 PM unterhaus: turns out a soldering iron is a decent tool to remove silicone potting
10:41 PM XXCoder: advanced lathe use https://media.discordapp.net/attachments/582328073878241303/795870497782104104/20210104_231923.jpg?width=1253&height=593
10:44 PM Tom_L: one could argue that's the wrong cutter type for that task
10:44 PM XXCoder: my concern would be chips as well as spraying ways with food
10:53 PM Tom_L: the ways are too clean anyway
11:04 PM CaptHindsight: when the only tool you have is a lathe....
11:12 PM CaptHindsight: XXCoder: heh https://www.instructables.com/Turn-Your-Food-on-a-Lathe-Made-from-a-drill-press/
11:12 PM XXCoder: looking
11:12 PM XXCoder: "Are you ever frustrated by the lack of rotational symmetry in some of your vegetables? No? Hmmm" lol
11:15 PM XXCoder: funny lol cool
11:45 PM _unreal_: UP mrec always up cut
11:46 PM _unreal_: unless the acrylic is floating meaning flange OR mounted the cutting area having nothing below it then you can use a down cut
11:47 PM _unreal_: you can use straight flutes BUT you have to have air or water removing the chips
11:48 PM _unreal_: and its better to use cutting methods that walk along like adaptive cutting method.
