03:49 PM Tom_L: :)
03:58 PM Deejay: gn8
04:34 PM Nick001-Shop: <pcw_mesa>Will your card drive a Pico servo amp?
04:44 PM CaptHindsight: Nick001-Shop: what inputs does the amp have? Step & Dir, +- 5V, +-10V, ??
04:45 PM CaptHindsight: https://sourceforge.net/p/emc/mailman/message/26880948/
04:46 PM CaptHindsight: https://pico-systems.com/acservo.html
04:46 PM Nick001-Shop: +-10 v
04:47 PM CaptHindsight: Nick001-Shop: http://store.mesanet.com/index.php?route=product/product&product_id=120
04:54 PM Nick001-Shop: The technical page is https://pico-systems.com/pwm_pins.html . I have the 7177 cards, just need to find out if it will deal with this particular amp and how I'm hooking it up. It takes a higher voltage than an AMC card and the amps are where I need them.
04:58 PM skunkworks: IIRC you need to do something special with the pico amps to initalize them.. some hal trickery..
04:59 PM Nick001-Shop: any documentation for this trickery?
05:07 PM pcw_mesa: Nick001-Shop: yes if they will take 5V signals a step/dir card (with PWM firmware) will drive them
05:10 PM Nick001-Shop: The tech sheet says PWM+ PWM Direction + Direction - +12vPower Doesn't say what voltage the PWM is
05:15 PM pcw_mesa: Pretty sure 5V is OK
05:18 PM pcw_mesa: ( for PWM and DIR )
05:18 PM pcw_mesa: enable needs 12V
05:20 PM Nick001-Shop: Thanks for the info.
05:20 PM Nick001-Shop: Oh well, the lube tank popped a gasket -shut down the Hardinge. It's dinner time so tomorrow is another day. Nite

05:59 PM jthornton: at least it will be above freezing during the day the rest of the week
06:10 PM andypugh: Youtube thought I would like to see this. As usual, Youtube was correct, even though there are no otters or owls: https://youtu.be/1rfaJsPMZIE
06:12 PM perry_j1987: such a tiny endmil they got there :P
06:13 PM andypugh: Hilarous isn’t it?
06:13 PM perry_j1987: feeds and speeds calculator didnt go big enough they had to manually calculate it heh
06:14 PM FinboySlick: andypugh: I agree that the otter is missing.
06:15 PM andypugh: Have you seen the “desk weasel” on YouTube?
06:16 PM FinboySlick: I guess when you can't be bothered to design a tool changer, an ABB robot will do just fine.
06:16 PM jthornton: hmm my FatShark FPV goggles should be here tomorrow... we'll see if they work with glasses or not
06:16 PM FinboySlick: Can't say that I have seen the desk weasel, no.
06:16 PM FinboySlick: I'm familiar with Bingo the otter though.
06:16 PM FinboySlick: And his arch-nemesis, the IKEA shark.
06:17 PM perry_j1987: some flex on that tool around 2:48
06:19 PM FinboySlick: Not quite as good a music as the 3d laser engraving dudes CaptHindsight linked a few days ago though.
06:20 PM FinboySlick: Darn, I need to find those again.
06:20 PM FinboySlick: Been meaning to fish out the artist.
06:30 PM jymmmm: Australia wildfires this year so far burned 2.1 MILLION ACRES
06:32 PM Tom_L: started by pacific power?
06:32 PM jymmmm: No
06:33 PM jymmmm: They actually came from austrailia last year to help with the fire here
06:33 PM Tom_L: what causes theirs?
06:33 PM FinboySlick: PG&E's incompetence stretches across the pacific?
06:34 PM jymmmm: IDK
06:34 PM Tom_L: they used to burn cane.. dunno if they still do
07:35 PM CaptHindsight: perry_j1987: likely going tomorrow

07:36 PM perry_j1987: aye usually possible snow by late december
07:37 PM perry_j1987: we've already had two snowstorms here
07:37 PM CaptHindsight: right around Thanksgiving is our usually very first dusting of light flakes
07:38 PM CaptHindsight: already tired of shoveling
07:38 PM perry_j1987: need a roomba snow bot
07:39 PM CaptHindsight: I think the candians figured some way of just passing cold air right on over them from Russia to us
07:39 PM perry_j1987: lol
07:39 PM CaptHindsight: Canadians even
08:17 PM _unreal_: just got an other part on my daughters cnc machine done
08:17 PM _unreal_: the Y axis wire carrage
08:17 PM _unreal_: just some alunium 1"x1/8 stock cut drilled and held together with a 6-32 as a hinge :)
08:18 PM _unreal_: gots in the bottom to carry the wires
08:18 PM _unreal_: I'm thinking I may purchase a short bit of the real. wire chain stuff for the top
09:09 PM CaptHindsight: i need a laser guided sheet metal punch
09:10 PM CaptHindsight: to disintegrate metal ~1/4" dia up to 1/8" thick
09:11 PM FinboySlick: CaptHindsight: Trumph 2020!
09:11 PM FinboySlick: Wait.... That sounded way too much like a political slogan.
09:11 PM CaptHindsight: heh
09:11 PM CaptHindsight: he whats the idea of sendin us all yer cold airs?
09:11 PM FinboySlick: https://www.youtube.com/watch?v=EU3SKaBFHIk
09:12 PM FinboySlick: Just so people don't think I'm being partisan.
09:12 PM CaptHindsight: i want hand held
09:12 PM CaptHindsight: you walk up to so sheet metal and just blast a hole through without a projectile
09:13 PM CaptHindsight: so/some
09:14 PM CaptHindsight: i always have to end up drilling some mounting hole after everything is bent and painted
09:14 PM CaptHindsight: FinboySlick: is partisan some sort of cheese?
09:15 PM CaptHindsight: as in " I'll have my pasta with shredded partisan on top"
09:15 PM FinboySlick: Yeah, even more stinky than parmesan, but just as 'regiano'.
09:18 PM CaptHindsight: somebody here had a punchpress
09:18 PM CaptHindsight: what was the guy down in Atlanta that built planes for a hobby?
09:18 PM CaptHindsight: he kept his house too warm one day :)
09:19 PM CaptHindsight: hasn't been around here in a few years
09:19 PM FinboySlick: CaptHindsight: That almost sounds like the sound of a poem/limerick.
09:19 PM FinboySlick: *start I mean.
09:20 PM CaptHindsight: there once was a guy from Atlanta
09:20 PM CaptHindsight: he built planes for fun and drank Fanta
09:20 PM CaptHindsight: he turned on his laser....
10:12 PM Tom_L: capn, ssi?
