12:00 AM Tom_L: :)
12:11 AM Tom_L: how will that hold up to weather?
12:22 AM Tom_L: ok finally got it to accept the parameters i gave it
12:24 AM rue_mohr: so, maybe that can by dry storage for the winter for some things
12:24 AM rue_mohr: it needs a door door
12:24 AM rue_mohr: leaks aren't really an issue, that fan seems to be too big
12:24 AM Tom_L: you _could_ shut the fan off when not inside couldn't you?
12:25 AM rue_mohr: not really
12:25 AM rue_mohr: it does hold it up
12:25 AM Tom_L: and start it when you need access?
12:25 AM rue_mohr: I dont think it could unpool water
12:25 AM Tom_L: i can see that fan getting froze up in the winter
12:25 AM rue_mohr: and having it pressurized means that if there are leaks, the air will push water away
12:25 AM rue_mohr: ?
12:26 AM rue_mohr: I think it would be ok
12:26 AM Tom_L: sucking cold moist air thru it
12:26 AM rue_mohr: not sure on snow tho
12:26 AM Tom_L: that's somewhat what i meant
12:26 AM rue_mohr: its an experiment
12:26 AM rue_mohr: going well so far
12:26 AM Tom_L: have you engraved alum?
12:26 AM Tom_L: with a engraving bit
12:26 AM rue_mohr: yes
12:27 AM Tom_L: what S & F did you use?
12:27 AM rue_mohr: last engrave was plexiglass tho
12:27 AM rue_mohr: hmm
12:27 AM rue_mohr: its a 1 flue V bit
12:27 AM Tom_L: i've got a good idea but what i entered seems slow
12:27 AM rue_mohr: probably about 2000rpm, and 50mm/min
12:28 AM rue_mohr: I tend to use too much speed
12:28 AM Tom_L: 2 ipm?
12:28 AM rue_mohr: "yes"
12:28 AM Tom_L: i went with 4k rpm @ 3.2 ipm
12:28 AM Tom_L: may bump that up a bit
12:28 AM Tom_L: on the feed
12:29 AM rue_mohr: plexi is the opposite, its like 500rpm and 100mm/min
12:29 AM rue_mohr: much rpm and you get all kinda of hair
12:30 AM rue_mohr: I need to finish this meter
12:30 AM rue_mohr: got almost no energy
12:30 AM Tom_L: ok i'm gonna try 4k rpm @ 4ipm
12:30 AM rue_mohr: the air was thick with smoke from a local fire today
12:31 AM Tom_L: forest or house?
12:31 AM rue_mohr: forrest
12:31 AM rue_mohr: I'm curious if that shed will just be flapping pieces of plastic in the morning
12:32 AM Tom_L: does that tape stick pretty well?
12:32 AM rue_mohr: its quite solidly inflated
12:32 AM rue_mohr: yes
12:32 AM Tom_L: when it's frozen too
12:32 AM rue_mohr: its tuck tape, insane stuff
12:32 AM rue_mohr: mmm
12:32 AM Tom_L: not familiar with it
12:32 AM rue_mohr: I'll finish taping the inside too
12:33 AM rue_mohr: I also dont see a UV rating on it
12:34 AM Tom_L: ok i think i'm pretty happy with this now
12:34 AM Tom_L: the big holes get milled, the small ones get drilled
12:36 AM rue_mohr: I could do some really big stuff with this inflated thing
12:36 AM Tom_L: go get a 'bouncy house' and remove the floor
12:36 AM rue_mohr: heh
12:37 AM rue_mohr: it was hard to find a 9x12' space for this
12:37 AM Tom_L: there's a swiming pool here that has an inflatable cover
12:37 AM Tom_L: public pool
12:37 AM Tom_L: how big is that fan?
12:38 AM Tom_L: i wonder if the squirrel cage fan from a car would be big enough
12:38 AM rue_mohr: 1/6 HP
12:38 AM rue_mohr: yup
12:38 AM rue_mohr: or 1/10
12:38 AM Tom_L: is that what you're using?
12:38 AM rue_mohr: hmm I dont remember
12:38 AM rue_mohr: yes
12:38 AM Tom_L: :)
12:38 AM rue_mohr: its just a blower
12:38 AM rue_mohr: oh its not a car fan
12:38 AM rue_mohr: its 120VAC
12:39 AM Tom_L: oh
12:39 AM rue_mohr: but its 1/6-1/10 HP
12:39 AM Tom_L: i got a fair size one in the shop for exhaust
12:39 AM Tom_L: used it alot when i did spraying
12:39 AM rue_mohr: hmm
12:39 AM Tom_L: 10-12" duct
12:40 AM Tom_L: i don't remember now
12:40 AM rue_mohr: thats an air mover
12:40 AM Tom_L: yeah
12:40 AM rue_mohr: I cant see working out indoor welding space in my new shop
12:41 AM Tom_L: i did most of my mill inside
12:41 AM Tom_L: just careful
12:41 AM Tom_L: more worried about the grinding than the welding
12:46 AM Tom_L: where did you find a zipper that size?
12:09 PM rue_mohr: they sell them at the builing supply store as hoarding supplies

04:25 PM rue_shop2: :)
04:26 PM rue_shop2: did you make a new top then?
05:20 PM Tom_L: working on it
06:44 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/pendant/new/Pendant1.jpg
07:07 PM rue_shop1: UDMA_CRC_Error_Count 366
07:07 PM rue_shop1: one of the new drives on the shop fileserver is having DMA issues
07:08 PM rue_shop1: Tom_L, looks good
07:08 PM Tom_L: didn't you have a bad one already?
07:08 PM rue_shop1: their new
07:08 PM Tom_L: i know but wasn't one bad?
07:08 PM rue_shop1: just checked the logs and noticed its not happy
07:08 PM rue_shop1: no... their new...
07:08 PM Tom_L: mmm
07:09 PM rue_shop1: Power_On_Hours 4145
07:09 PM rue_shop1: I dont know if that can be caused by a bad cable...
07:10 PM rue_shop1: Device Model: WDC WD42PURZ-85B4YY0
07:10 PM rue_shop1: I did different models on the raid drives
07:10 PM rue_shop1: no 'oops that whole line was faulty' problems
07:10 PM Tom_L: so they fail at different times?
07:11 PM rue_shop1: yea
07:11 PM rue_shop1: aka, I probably have time to replcae one before the second fails
07:11 PM rue_shop1: (unelss the power supply explodes everyone)
07:11 PM Tom_L: those must be more rugged than the average rust bucket
07:13 PM rue_shop1: ?
07:13 PM Tom_L: the purple drives
07:13 PM rue_shop1: the last drives had like...
07:14 PM rue_shop1: 100k hrs on them
07:14 PM rue_shop1: still worked, but I was getting a bit worried
09:31 PM rue_shop2: well, I bascially got nothing done this weekend
09:55 PM Tom_L: it's ok.. one of us did for a change
09:58 PM rue_mohr: :)
09:59 PM Tom_L: doing that face helped me fix the pendant anyway... must have had a loose wire or something. the scale switch wasn't working right but now it is
10:00 PM Tom_L: for the .0001 .001 .01 steps per click on the pendant
10:00 PM rue_mohr: nice
10:00 PM rue_mohr: you were chasing that as a programming issue for a while weren't you?
10:02 PM Tom_L: it's a binary switch and i'd narrowed it down to one signal
10:03 PM Tom_L: http://linuxcnc.org/docs/stable/html/man/man9/mux4.9.html
10:03 PM Tom_L: one of .sel0 or .sel1 wasn't tripping
10:03 PM rue_mohr: :)
10:04 PM rue_mohr: hmm, I should have looked at my todo list
10:04 PM Tom_L: then that goes thru a lowpass thing i also was checking
10:04 PM Tom_L: you built a hut
10:04 PM Tom_L: that's something...
10:05 PM Tom_L: http://linuxcnc.org/docs/stable/html/man/man9/ilowpass.9.html
10:05 PM Tom_L: that makes the steps on the mpg more linear instead of cogging
10:06 PM rue_shop2: meh
10:06 PM rue_shop2: I'm working on that old meter
10:06 PM rue_shop2: I should have finished it by now
10:06 PM Tom_L: the one you printed?
10:06 PM rue_shop2: the final details of the trim system are being annoying
10:06 PM rue_shop2: yea
10:07 PM Tom_L: i kinda nursed my way thru that program... it wasn't without flaw but i made it work
10:09 PM Tom_L: i had to mill nearly half that blank i made that from, i didn't have anything the right thickness
10:17 PM rue_shop2: :)
10:17 PM rue_shop2: 3 passes later
10:18 PM rue_shop2: this week I plan to mill out the top of the pillow blocks for the steam engine
10:18 PM rue_shop2: and find a lighter fan solution for the shed
10:18 PM rue_shop2: and build it airlock doors
10:18 PM Tom_L: for some reason the cutters were all deeper than they were supposed to be
10:19 PM Tom_L: so i stopped on the engraving bit and pulled it into it's own program and reset the bit
10:19 PM Tom_L: it was still a little deeper than i'd liked
10:20 PM Tom_L: ok, i'm goin to sleep, pooped out
10:39 PM rue_shop2: gnight
