07:25 AM Tom_L: hi
09:00 AM rue_mohr: hi
09:00 AM rue_mohr: did you hear wormfood has been in chineese prison since 2008!?
12:31 PM Tom_L: nope
05:41 PM spline: wow uhm efnet wormfood?
05:41 PM spline: I used to talk to him
06:12 PM Tom_L: same
07:04 PM rue_mohr: hi
07:05 PM rue_mohr: is be in #avr still?
07:05 PM rue_mohr: yup
07:11 PM Tom_L: not me
07:11 PM Tom_L: hi
08:00 PM Tom_itx: Thank you for contacting Geckodrive technical support. There is no issue powering up a drive without a motor. The drive will just draw quiescent current of about 30mA and sit there until you connect a motor and tell it to move.
08:00 PM Tom_L: good to know
09:40 PM Tom_L: so
09:41 PM Tom_L: i went out to wire up the 1k pulldown etc inside the pendant for A axis and it was already done
09:41 PM Tom_L: i must have been thinking ahead when i wired it
09:41 PM Tom_L: had one undocumnted wire so i added that to the pdf
09:50 PM Tom_L: wires already run to behind the heatsink for power and signal. all i need to figure out is at least one limit switch for home
09:59 PM rue_mohr: :)
10:19 PM Tom_L: i might use Z- since it never gets used
10:19 PM rue_mohr: ?
10:19 PM Tom_L: limit switch for A
10:19 PM rue_mohr: I thought you had an A on your pendant
10:19 PM rue_mohr: oh
10:19 PM Tom_L: i do
10:20 PM rue_mohr: why do you need a limit switch
10:20 PM Tom_L: just to home it
10:20 PM rue_mohr: it just rotates
10:20 PM rue_mohr: but
10:20 PM rue_mohr: dont you manually home those?
10:20 PM Tom_L: so it has a starting reference
10:20 PM Tom_L: not necessarily
10:20 PM rue_mohr: a limit switch will land somewhere different every time
10:20 PM Tom_L: they're fairly repeatable
10:20 PM rue_mohr: hmm, I had to use an opto-interrupter
10:21 PM rue_mohr: https://pubs.rsc.org/image/article/2018/AY/c8ay00446c/c8ay00446c-f2_hi-res.gif
10:21 PM rue_mohr: (not related)
10:21 PM Tom_L: i have one of those i could use
10:22 PM Tom_L: i took it off the original spindle encoder
10:22 PM rue_mohr: I put a notch in the shaft
10:22 PM rue_mohr: and a lever rides the shaft and falls into it
10:22 PM rue_mohr: blocking the opto
10:23 PM Tom_L: well that way it could pass thru and not break anything
10:24 PM rue_mohr: well, I cant have icecream for supper
10:24 PM rue_mohr: there wasn't enough left
10:24 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/new_pulley_mounted2.jpg
10:24 PM Tom_L: if i can find it
10:24 PM rue_mohr: :)
10:25 PM Tom_L: i have more but not set up
10:25 PM rue_mohr: I dont want rive
10:25 PM rue_mohr: rice
10:25 PM rue_mohr: noodles would be ok
10:25 PM Tom_L: i had noodles
10:25 PM rue_mohr: ok, I'll go start some water
10:26 PM rue_mohr: if I can get up
10:26 PM Tom_L: don't let it boil dry
10:26 PM rue_mohr: I dont put the noodles in till its safely boiling
10:26 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/spindle_enc8.jpg
10:26 PM Tom_L: i'm surprised that little encoder hasn't given up yet
10:27 PM Tom_L: small shaft for that pulley
10:27 PM Tom_L: but
10:27 PM Tom_L: it is ballbearing
10:28 PM rue_mohr: I should makea cover for the one that does the speed regulation on mine, dusty
10:28 PM Tom_L: i thought my belt cover came out rather well
10:28 PM Tom_L: for never making one before
10:28 PM Tom_L: well lookie there
10:29 PM rue_mohr: I should play with some sheet metal stuffs
10:29 PM rue_mohr: the compressor could use a belt cover
10:29 PM Tom_L: you don't see j and p do you
10:29 PM Tom_L: join...
10:29 PM WormFood: and spline is here too

10:33 PM spline: yeah uhm what happened w/the china and jail thing?
10:33 PM WormFood: I'm gonna do a reddit ama (ask me anything)
10:33 PM spline: ah gotcha
10:34 PM WormFood: I don't want to go over everything for everyone. I'd rather just do it once.
10:34 PM Tom_L: well practice here
10:34 PM WormFood: hahaha
10:34 PM WormFood: I don't need to practice
10:34 PM spline: gotcha

10:35 PM WormFood: yeah, in Liberia
10:35 PM * WormFood knows a guy from Liberia
10:36 PM WormFood: IRC still isn't mainstream, despite being around longer than the web
10:36 PM rue_mohr: thats why undernet and #mp3_collective
10:36 PM Tom_L: just as soon keep it that way
10:37 PM WormFood: But we need more women here.
10:37 PM Tom_L: mainstream draws too many flies
10:37 PM WormFood: By the way, I've met both of the women on IRC now.
10:37 PM Tom_L: there's been a few
10:37 PM Tom_L: rebecca from Au
10:37 PM WormFood: I know. But still, maybe what? 1-2%

10:48 PM rue_mohr: polprog, why are we always at tangents?
10:49 PM Tom_L: so what else could i put on a 4th axis?
10:49 PM rue_mohr: no?
10:49 PM Tom_L: rotary, live tooling...
10:49 PM Tom_L: what else
10:51 PM rue_mohr: r-theta mode?
10:52 PM Tom_L: i also need to figure out how to use the cad cam on a rotary
10:52 PM Tom_L: it only programs an indexer
10:52 PM Tom_L: wish it did live rotation
10:53 PM rue_mohr: I thought you only use it to help hand-code your parts?
10:53 PM Tom_L: f360 might but i'm not gonna load that
10:53 PM Tom_L: i need to make a post that will work with it too
10:54 PM Tom_L: i have a few with rotaries in them but i've never used em
11:01 PM rue_mohr: so, you can make cams
11:01 PM rue_mohr: with custom programs...
11:06 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/dw03.pdf
