12:07 AM veegee: https://www.youtube.com/watch?v=J02ricbIIvc is this a guy or a girl?
12:13 AM veegee: I genuinely can't tell
01:35 AM Deejay: moin
01:45 AM W1N9Zr0: veegee: are you 12 years old or just insecure? what's this "hurr durr, she looks like a man" crap? Blondihacks is a woman, and a well-known youtube hobby machinist
01:49 AM XXCoder: vee what does gender change?
01:49 AM XXCoder: in terms of machinist skills not whatever youre hiding under clothes
01:50 AM XXCoder: i have met ladies that would kick my ass in terms of skills
03:09 AM sensille: now i want a steady rest
04:35 AM unterhaus: I have a steady rest, I want the kind that moves
05:06 AM JT-Cave: morning
05:37 AM Tom_L: morning
05:39 AM Tom_L: 24F hi 45
05:59 AM JT-Cave: 33.7°F in the coop this morning
06:02 AM JT-Cave: I got $1200 from the IRS yesterday
06:09 AM unterhaus: I think we got 525
06:10 AM unterhaus: get more when we file taxes
06:13 AM unterhaus: I guess I'm going to go chisel away at some silicone potting. Might have to sharpen my 1/8" chisel
07:43 AM jymmmm: Morning
08:28 AM unterhaus: it's like they didn't want me to remove that potting or something
08:29 AM unterhaus: the things I'll go through to save $35
08:30 AM unterhaus: well, people are asking more than retail on ebay
08:38 AM unterhaus: I used to have a lot more energy to search for encoder cables on ebay
08:41 AM _unreal_: ya clicking on web pages is like running the Bostin Marathon
08:41 AM _unreal_: lol
08:59 AM _unreal_: perry_j1987, just rememberedd the other one https://hackaday.io/project/11583-odrive-high-performance-motor-control ODRIVE
09:45 AM Tom_L: JT-Cave, yeah i thought they were just wishing me happy new year
09:46 AM Tom_L: morning jymmmm
10:09 AM JT-Cave: who dat Tom_L
10:52 AM Tom_L: JT-Cave, the irs
11:18 AM JT-Cave: did you get yours before the new year?
11:18 AM Tom_L: showed on the 3rd
11:19 AM JT-Cave: mine came on the 2nd
11:28 AM Tom_L: they'll get it back in 3-4 mo anyway
11:28 AM JT-Cave: hurry up and spend it so they can't take it back next month
11:29 AM Tom_L: not sure that's how that works :)
11:32 AM JT-Cave: nap time here
11:33 AM Tom_L: pretty close
11:33 AM Tom_L: lunch then nap
12:29 PM perry_j1987: morning
01:25 PM -!- #linuxcnc mode set to +v by ChanServ
01:32 PM Loetmichel: re from a Visit at sisters home... 245km one way... i think that BMW is tired... had to fill in 2.5l oil because of "Low oil" warning. MAAN i filled that up not even 1500km ago... :(
01:36 PM gloops: 2.5litres is like a lifetime supply of engine oil lol
02:13 PM unterhaus: Loetmichael I saw a German speaker use "massive" instead of "solid" Does that make sense?
02:15 PM Loetmichel: unterhaus: yes
02:16 PM Loetmichel: in german its "Massivleiter" vs. "Litze" (solid wire vs stranded wire)
02:16 PM Loetmichel: "massiv" means not only "high mass" but also "one piece, no hollows within"
02:17 PM Loetmichel: in german
02:17 PM Loetmichel: s/hollows/voids?
02:19 PM unterhaus: thanks
02:37 PM roycroft: lovely - i'm not able to get any of the work done today that i had planned
02:38 PM roycroft: one of my users is a freebsd developer, and apparently there was just a big commit a half hour ago
02:38 PM Loetmichel: unterhaus: so when someone says "a massive block of granite" it can mean either a big block or a solid block of even both.
02:38 PM Loetmichel: someone german
02:38 PM roycroft: as a result, she's getting tens of thousands of commit emails from two freebsd mailing lists, causing my mail server to reject all incoming connections, and causing proofpoint to queue all messages to my mail server
02:39 PM roycroft: so i cannot get any emails at all now, and i'm in the middle of doing some work that requires a number of emails
02:40 PM roycroft: imo it's pretty poor behavior for the freebsd folks to send tens of thousands of emails like that
02:40 PM roycroft: at the very least they should put them in digest form or something when there's going to be a flood of messages
02:57 PM flyback: *CANUCKED*
02:57 PM flyback: *CANUCKED*
02:57 PM flyback: *CANUCKED*
02:57 PM flyback: *CANUCKED*
02:58 PM flyback: https://youtu.be/9el1GI4gUxk?t=199
02:58 PM * flyback dashes elmo40 against the bearing
03:13 PM JT-Shop: can't you block them?
03:16 PM _unreal_: perry_j1987, did you see that message?
03:26 PM * JT-Shop waits for the loctite to cure on the wagon vise
03:29 PM Tom_L: JT-Shop, building a workbench?
03:29 PM enleth: roycroft: it's not so simple - users normally disable digests because they're pretty much useless for anything
03:30 PM enleth: second, it's really an emergent behavior - no one is literally intending to send so many messages
03:30 PM enleth: but as a side effect of some things, that's what happened
03:30 PM roycroft: i get digest of almsot all my high volume lists
03:30 PM roycroft: digests
03:31 PM enleth: you're in a significant minority, then - digests are effectively read-only, you can't easily respond to a given message because you never got that message, technically speaking
03:31 PM roycroft: i'm still trying to sort out why there are so many messages though
03:32 PM enleth: someone might goofed up some config or some action, as well
03:32 PM enleth: *might have
03:32 PM roycroft: i've found out that the poster only made 200 commits today
03:32 PM enleth: or a git bot did something dumb
03:32 PM roycroft: apparently this person makes about that many commits on a daily basis
03:32 PM roycroft: but each commit goes two two mailing lists
03:32 PM roycroft: and there are always a bunch of bounces back to the list
03:33 PM roycroft: but even adding all of that up, there should be maybe a couple thousand messages in total
03:33 PM roycroft: and i saw over 57,000 in less than an hour
03:33 PM roycroft: so something is wrong upstream
03:33 PM enleth: roycroft: I might be able to reach someone responsible for freebsd mailing lists, if that would help
03:34 PM roycroft: the commits are done, and mail is slowly trickling in again
03:34 PM roycroft: i'm trying to get ahold of my user
03:34 PM roycroft: i'd rather the user sorted it if possible
03:34 PM roycroft: if not, i'll contact the freebsd folks myself
03:34 PM enleth: sure
03:34 PM roycroft: but thanks for the offer
03:35 PM roycroft: this election for speaker of the house is really down to the wire
03:35 PM roycroft: but pelosi just won
03:35 PM roycroft: by a razor-thin margin
03:35 PM roycroft: she needed 214 votes, and got 215
03:36 PM roycroft: oh, she just got one more vote
03:37 PM roycroft: anyway, i should head off to the shop while the mail server is slowly recovering
03:37 PM roycroft: i wasn't going to do any shop work today, because i needed to open the big door for a while to do some maintenance on y car, so the shop is not heated
03:38 PM roycroft: but i have jackets :)
03:40 PM JT-Shop: Tom_L, yea sorta a mini workbench on wheels but mostly a place to store clamps and other stuff and a place to sand stuff hence the wagon wheel vise
03:45 PM unterhaus: WFH is nice because I don't have to worry about my wife crashing into people in the snow
03:45 PM unterhaus: like one does
03:45 PM roycroft: i'd have to drive for an hour up into the mountains to find an opportunity to crash into people in the snow
03:46 PM roycroft: i'm not particularly interested in that
03:55 PM veegee_: I don't tip delivery people
03:58 PM skunkworks: I would think that would only work once.. After that - I would be afraid what was in the food next time.
03:58 PM Tom_L: :)
03:58 PM veegee_: They're starting to add anti tamper seals
03:59 PM veegee_: Also I always get a different delivery asshole every time
03:59 PM veegee_: Despite very clear instructions on how to access the unit, they always waste my time
03:59 PM veegee_: BUT I keep change on me for the good ones
03:59 PM veegee_: If they don't waste my time, they get a tip
04:01 PM veegee_: roycroft I'm giving your M42 endmills a shot, let
04:02 PM veegee_: let's see how they hold up vs the solid carbide endmills
04:02 PM veegee_: I do appreciate the surface finish I get with HSS. I wonder how 5-8% cobalt affects that
04:05 PM veegee_: I so want to add servos and convert my lathe to CNC, but I need to order custom ball screws for it
04:06 PM veegee_: The ACME screws have your typical backlash. Not sure how well linuxcnc can compensate for backlash. It already has a digital readout and scales with 1µm precision and 5µm accuracy though so I guess that should eliminate any issue backlash causes?
04:09 PM veegee_: Also replaced my flint striker for the oxy acetylene torch with a plasma arc lighter. Those flints don't last very long and it's annoying to use
04:36 PM unterhaus: I'm pretty sure I have extra flints for my striker and never used one
04:37 PM unterhaus: I have a gas saver, but I have never hooked it up
04:38 PM unterhaus: when I built bike frames, we had gas saver torches, but those are dangerous
04:38 PM unterhaus: pretty much just leaked acetylene so that the flame never went all the way out
04:39 PM unterhaus: they tried to sell them to us after one caused an explosion that shook the building
04:39 PM unterhaus: I did like it though
05:01 PM _unreal_: so my laser etcher that is not suposed to show up for like 3-4 days just showed up
05:01 PM _unreal_: heh
05:01 PM _unreal_: WTF
05:19 PM perry_j1987: hows it going guys
05:28 PM JT-Cave: making sourdough crackers...
05:45 PM perry_j1987: nice
05:45 PM perry_j1987: found some big cast iron legs out at the shop to put on the new lathe
05:45 PM perry_j1987: gotta get some hardware to bolt it all together
06:46 PM sinned6915: JT-Cave: what recipe? how did it turn out? I have 4+ cups of discard to deal with
07:22 PM perry_j1987: anyone have couple g320x drives for sale? :P
07:23 PM XXCoder: I do, get me million usd and ill send you a couple for free,
07:24 PM perry_j1987: lol
07:24 PM XXCoder: :)
07:24 PM XXCoder: few people look at "free" word first
07:26 PM perry_j1987: found a pair for 200 with shipping included
07:26 PM XXCoder: https://imgur.com/gallery/C5IPsNw#bviQBNW very nice!
07:28 PM perry_j1987: good use of 3d printing
07:28 PM XXCoder: yeah
07:32 PM enleth: he's also using lasercut HDF to build a form flask
07:34 PM perry_j1987: how does one choose what voltage to run servos at
07:37 PM enleth: perry_j1987: generally one doesn't - why do you think you need to?
07:38 PM perry_j1987: cause i need to shop for a power supply
07:38 PM perry_j1987: lol
07:38 PM enleth: ah, that kind of "choose"
07:38 PM enleth: I thought you mean configuration of servo drives
07:39 PM enleth: but my answer is actually still correct - just feed the servo drives something close to their maximum voltage
07:39 PM perry_j1987: The servos are MCG Part No: 2234 - M4130 Torque Cont: 50.00 oz - in. Current Cont: 1.99 Amps
07:39 PM enleth: the more voltage they get, the more they can use to counter back-EMF
07:40 PM enleth: doesn't matter what the servos are at this point, the only factor to consider when choosing the power supply is maximum input voltage of the servo drives
07:40 PM perry_j1987: i dont have that number
07:40 PM perry_j1987: oh the drives?
07:41 PM enleth: yes, the drives, they should list that value in the datasheet
07:41 PM perry_j1987: looks like i need g320x drives
07:42 PM enleth: the only component in the whole system that "sees" this voltage directly is the input side of the MOSFETs in the servo drive
07:42 PM enleth: the whole notion of "maximum voltage" as applied to the servo itself is somewhat meaningless
07:43 PM jdh]: why the geckos? why step/dir?
07:43 PM enleth: sure, there's the winding insulation breakdown voltage, but it's way higher than anything you'd ever try feeding it
07:43 PM perry_j1987: i have no idea jdh] lol
07:43 PM jdh]: what are you going to control them with?
07:44 PM perry_j1987: thinking of just doing a parport bob for now
07:44 PM enleth: also, yeah, using a step/dir drive for servos is like buying a race horse and putting galoshes on it for a race
07:45 PM jdh]: the existing servo drives are on the proprietary card?
07:45 PM perry_j1987: ok im securely seated in my recliner and got a drink at my side im ready to go back to square one lol
07:45 PM perry_j1987: ya existing servo drives are on this board http://support.technocnc.com/pdf/0229_LC_and_Lathe_Board-Callouts-Connectors.pdf
07:46 PM perry_j1987: there is some pci card that i dont have that ran the show
07:46 PM enleth: perry_j1987: it will work, it's just... meh.
07:46 PM perry_j1987: this board is the psu, servo drives etc
07:46 PM enleth: still better than steppers, should eliminate missed steps
07:46 PM perry_j1987: what are my options?
07:47 PM jdh]: geckos, cheap AMC's, leadshine?
07:47 PM jdh]: step/dir would be simple and probably cheapish
07:48 PM enleth: those are brushed DC servos, right?
07:49 PM perry_j1987: ya brushed
07:49 PM perry_j1987: http://www.techno-isel.com/Education1/Ed_MetalLathe.htm this is the lathe
07:49 PM jdh]: if you knew what JP4/P6 were, you might be able to just use that board.
07:49 PM perry_j1987: https://www.cnczone.com/forums/attachment.php?attachmentid=299470&d=1448923108
07:50 PM perry_j1987: jp4 is not populated on the actual board
07:50 PM perry_j1987: and p6 is not populated
07:50 PM perry_j1987: jp2 is the interface used
07:51 PM perry_j1987: but no clue what type of signals etc
07:51 PM enleth: perry_j1987: something like this: https://www.ebay.com/itm/Advanced-Motion-Controls-12A8E-Brush-Type-PWM-Servo-Amplifier/163676589711?epid=2308106385&hash=item261be28e8f:g:7twAAOSw7aNczb6Z
07:51 PM enleth: ebay queries are "advanced motion brush" and "copley controls brush"
07:52 PM perry_j1987: how the hell...
07:52 PM perry_j1987: that did not show up in all my searches
07:52 PM enleth: AMC and CC are the two manufacturers of really nice servo drives that are plentiful on ebay
07:52 PM jdh]: amc drives are often relabeled also
07:52 PM enleth: sub-$100 units are mostly 80s-90s technology, but so are brushed servos anyway
07:53 PM enleth: those drives are very simple, very robust and very hard to kill, so buying them used carries little risk of getting a dud
07:53 PM jdh]: for youre 2amp motors, pretty much anything you find will be overkill. turn down the current limit before use!
07:53 PM enleth: that 12A8E seems ideal
07:53 PM enleth: feed it 70V, turn down current limit
07:54 PM jdh]: enleth: I have probably 30 of them at work. maint. guys replace them all teh time because they are 'bad'
07:54 PM enleth: jdh]: what exactly goes 'bad' in them?
07:54 PM jdh]: nothing.
07:54 PM jdh]: well, sometimes they short them.
07:55 PM jdh]: most of mine are BLDC. the usual 'failure' is a bad hall wire on the motor end (the motors pivot into place)
07:55 PM enleth: the biggest reason I've seen of servo drives going bad is either an output short, or insufficient DC bus capacitance leading to overvoltage on braking
07:56 PM enleth: slap a honkin' big capacitor on the DC bus for the latter, don't be a doofus for the former
07:57 PM perry_j1987: well that will save me a bit of money for those 12A8E drives then
07:57 PM jdh]: they need a controller
07:58 PM enleth: yes, you can't control them with a BOB
07:58 PM enleth: but what you save on them, you can put in a Mesa card
07:58 PM perry_j1987: which one
07:58 PM enleth: you'll break even and end up with a much better setup
07:59 PM jdh]: geckos might be a better fit for easy/cheap setup
08:01 PM enleth: I think the correct combination is 7i77 as the I/O board and one of 7i92 or 5i25 or 6i25 for the FPGA - unless there's a single board with FPGA and servo drive outputs that I don't know of, which is possible
08:01 PM enleth: so let someone associated with Mesa confirm or correct that before you buy
08:01 PM enleth: 7i92 is connected to the PC over Ethernet, 5i25 is PCI, 6i25 is identical to 5i25 but PCI Express
08:02 PM perry_j1987: what is the benefit of this method over gecko step/dir and bob
08:02 PM jdh]: close the loop in Lcnc instead of on the drive
08:02 PM enleth: you'll be using servos as servos, with linuxcnc actually knowing where the axes are and being able to correct problems or react to them immediately
08:03 PM jdh]: but, for a little lathe like that. might not be worth the added complexity
08:03 PM perry_j1987: this lathe is huge to me haha
08:03 PM jdh]: 2amp max servos
08:03 PM enleth: OTOH, a little lathe like that is a nice way to learn setting up servos properly without shitting your pants when they do something unexpected
08:04 PM jdh]: heh, and unexpected things should be expected to occur.
08:04 PM perry_j1987: sounds terrifying
08:04 PM jdh]: less so at 2amps
08:06 PM enleth: that's not a 15kg 2.5kW servo that moves a couple hundred kilos of cast iron
08:06 PM perry_j1987: still prob enough to pinch a finger good though :)
08:06 PM enleth: I had to strap those with cargo straps to a pallet to keep them from jumping around when I first started setting up the Copley Controls drives I used to replace the original drive in my Bridgeport
08:08 PM enleth: perry_j1987: so you can go ahead with the steppers, but if you want to get the feel of retrofitting a *real* CNC machine, even though it's really a small one, go for actual servo drives
08:09 PM enleth: it'll take a lot more time, you'll definitely be frustrated and lost along the way, but you'll learn a lot more and it'll be fun
08:09 PM enleth: if you're in for that kind of fun
08:09 PM perry_j1987: ya that would be fun
08:09 PM perry_j1987: but i also just want to get the thing moving and start setting up gang tooling
08:10 PM enleth: your call then
08:10 PM enleth: you can always get the drives and Mesa card later
08:10 PM perry_j1987: aye
08:10 PM enleth: it's not like eBay will run out of those used AMCs
08:10 PM jdh]: and sell the geckos
08:13 PM perry_j1987: ya
08:13 PM perry_j1987: hmm
08:15 PM perry_j1987: ya i'd like to spread the money out and spend little bit in lots of areas atm lol
08:27 PM perry_j1987: what is the realworld effect of something like the g320x vs those amc /mesa solution
08:32 PM jdh]: probably somewhere close to nothing
08:35 PM perry_j1987: hmm lol
08:37 PM perry_j1987: ok
08:38 PM _unreal_: perry_j1987, did you see my message?
08:38 PM perry_j1987: when
08:38 PM _unreal_: perry_j1987, just rememberedd the other one https://hackaday.io/project/11583-odrive-high-performance-motor-control ODRIVE
08:38 PM _unreal_: well I'm happy I just got my laser etcher in the mail today. was NOT expec ting it
08:39 PM perry_j1987: ah thats for brushless though
08:39 PM _unreal_: I forget it may work on brushed as well
08:39 PM _unreal_: regardless that one has auto tuning features
08:39 PM _unreal_: and its still alive
08:40 PM perry_j1987: my options are - tear apart my current lathe and swap it over, 425oz steppers
08:40 PM perry_j1987: or get a couple g320x and another parport bob and get the new lathe up and running independantly
08:41 PM perry_j1987: i'd rather not tear down my current lathe
08:50 PM perry_j1987: maybe i should just go with clearpaths heh
08:51 PM _unreal_: again your choice
08:51 PM _unreal_: right now I'm agraviating over the fact that I cant put the @#$@#@#4 laser etcher together
08:51 PM _unreal_: because it is missing T nuts
08:52 PM perry_j1987: 3d printer to the rescue
08:52 PM _unreal_: they tossed in reg hex nuts with screws that are to short
08:52 PM _unreal_: 4 T nuts and 8 nuts MOTHER fuckers
08:52 PM _unreal_: good thing is I have T nuts BUT they are at work
08:52 PM _unreal_: with my box of tools
08:53 PM _unreal_: err parts etch and my new machine I'm building CNC that is
08:53 PM _unreal_: so this laser etcher I got is HUGE
08:53 PM _unreal_: 25x25" working area
08:53 PM _unreal_: I still cant believe I got one of the last 3 for $180
08:53 PM _unreal_: every other place has one's half the size for $100 more easy
08:54 PM _unreal_: ARG... this is going to drive me nuts I know I saw it but I dont know where it is
08:54 PM perry_j1987: what type of laser
08:57 PM _unreal_: So a year ago I saw a post using attiny85's. and there only goal is to drive stepper motors. they are setup simply as pass though. so STEP/DIR in for control, step dir out PASS though, and they READ quadrature encoders and compare the step auction to the encoder. if there is an ERROR they correct
08:57 PM _unreal_: 3wat
08:57 PM _unreal_: only a 3 watt but 25x25. and the lasers are inter changable. I could easly upgrade.
08:59 PM _unreal_: GOD ITS annoying having the machine at work already. I wanted to work on it during the break but my living setup that I HATE made me bring it into work. OOOOO CHRISTMAS bullshit WE just did christmas tonight with in 45min 2 hours ago after I got back with my daughter.
08:59 PM _unreal_: done over..
08:59 PM _unreal_: so ya I'm trying to find the code
08:59 PM _unreal_: its driving me nuts
09:01 PM _unreal_: https://github.com/jan-r/servo-stepper
09:01 PM _unreal_: this just with stepper output not PWM output
09:04 PM _unreal_: This is literally what I'm talking about https://reprap.org/mediawiki/images/thumb/a/a7/Hybrid_stepper_control.jpg/544px-Hybrid_stepper_control.jpg
09:52 PM flyback: https://www.ebay.com/itm/LCD-Digital-Caliper-Electronic-Gauge-Carbon-Fiber-Vernier-Micrometer-Ruler-6inch/372849653989?hash=item56cf9238e5:g:E5wAAOSwGYNfP0JO
09:52 PM flyback: this matches the look of the one bigCANUCK says is good
10:11 PM Rab: I dunno about bigCANUCK (Big Clive?), but it doesn't look so good to me. Harbor Fright sells ones with ground steel jaws and .0005" resolution for not much more, sometimes 10USD on sale.
10:22 PM mrec: _unreal_: I think I really have a touch off issue and the paper sliding trick is not a good way to get some accurate results.
10:24 PM mrec: I ordered a z-axis presetter and will do some experiments with that one
10:26 PM skunkworks: mrec: use a dowel pin or such for touchoff..
10:26 PM skunkworks: works way better
10:30 PM skunkworks: mrec: https://youtu.be/sXU0e2dmtwU?t=91
10:37 PM mrec: skunkworks: better than a z-axis presetter?
10:38 PM mrec: I'm off by 0.25 mm by using paper (it doesn't really matter much it's just some detail I need to solve down the way)
10:38 PM skunkworks: I have not played with one.. But I would assume a good z-axis presetter should be as good or better.
10:38 PM mrec: the bigger issue is that shitty freecad build system at the moment
10:39 PM mrec: I'm using freecad to generate the g-code it's absolutely okay but some issues in the path workbench have to be fixed
10:39 PM skunkworks: I am off I am off +/- .025mm usually
10:39 PM skunkworks: (.001")
10:39 PM mrec: I did not even remove the plastic from the aluminium square
10:39 PM skunkworks: I can jog at .001" incraments - so in -doesn't fit - out does..
10:40 PM mrec: bigger issues are the cutting strategy for me at the moment
10:40 PM mrec: is*
10:40 PM skunkworks: I have only started playing with freecad. again. after a few months.
10:40 PM skunkworks: it does seem to get better every time I use it.
10:40 PM mrec: I'd like to do the rough parts a little bit smaller and do a fine pass after that one..
10:41 PM mrec: it crashes a lot for me in the path tool
10:41 PM skunkworks: I have not played with toolpaths yet.
10:41 PM skunkworks: Does it do thread milling?
10:41 PM flyback: Tom_L, do you still have the mediatek flah prorammer url handy
10:41 PM flyback: nm I found it
10:42 PM mrec: skunkworks: I don't know I just use it for 3 axis milling, not turning
10:42 PM skunkworks: This would be milling threads..
10:42 PM mrec: I'm sure turning is full with bugs
10:43 PM mrec: but I'm also sure it will be resolved quickly
10:43 PM mrec: lots of small things... but this idiotic build system it's the worst part I've seen
10:44 PM skunkworks: I am just using appimage

11:46 PM perry_j1987: wonder what its going to be like running this new lathe with 3/4 baldor motor vs my current lathe who's motor is the size of a popcan lol
11:52 PM _unreal_: z axis pre setter?
11:52 PM _unreal_: I have no idea what that means
11:52 PM _unreal_: or what your refering to sorry mrec
11:53 PM _unreal_: OH TOUCH probing
11:53 PM _unreal_: dude USE touch probe
11:54 PM perry_j1987: should i use this lathes existing transformer and make up the rest of the supply, rectifiers/caps or go with new switching psu bricks
11:55 PM _unreal_: you have two choices. use a probe base and a clip to your milling tooling bit. OR contact a conductive surface and your tooling bit using clips
11:55 PM _unreal_: perry_j1987, what is the output of the psu in place?
11:55 PM perry_j1987: not sure yet
11:55 PM _unreal_: well I cant help yet LOL
11:55 PM perry_j1987: its got multiple voltages coming off it
11:55 PM _unreal_: o,O
11:56 PM _unreal_: well thats helpful......... NOT
11:56 PM _unreal_: is the lathe a 110, or 220
11:56 PM _unreal_: input
11:56 PM perry_j1987: 110
11:56 PM _unreal_: ok
11:57 PM _unreal_: the spindle does it run off a transformer or does it run off of 110
11:57 PM perry_j1987: there's a vfd in the case
11:57 PM _unreal_: OK. is it isolated from the/an other PSU-transformer
11:58 PM _unreal_: meaning does the VFD run off 110 or is it a DC-DC vfd
11:58 PM perry_j1987: 110 i believe
11:58 PM _unreal_: ok so its isolated
11:58 PM _unreal_: if its 110
11:58 PM _unreal_: BUT its still part of the same draw
11:59 PM _unreal_: the current PSU was designed for the motors that are on the machine provided everything is original.
11:59 PM _unreal_: the question is what is the output volts/amps
11:59 PM perry_j1987: https://lh3.googleusercontent.com/proxy/nZVQoI2iOUZLme7iXNHOm3hs5J8KPLjTsDPuwMHLANV5A1yXjItcxd7B-Az2_pLzQqEyx5CFx5OMKJA-3GnjG-bztBGGqnzKDqHwXa_-ZAMwBQE-glE
11:59 PM _unreal_: if the output volts are less then 24v consider a different PSU.
11:59 PM perry_j1987: best pic i can find inside cabinet heh
11:59 PM _unreal_: ok so it has a triod psu
