10:22 AM MoziM: hello
11:01 AM SomeT: does anyone here use ARIA? http://robots.mobilerobots.com/wiki/ARIA
01:09 PM robotustra: good day
01:37 PM SomeT: hi
01:37 PM SomeT: are you still there? lol
02:26 PM robotustra: of cause I'm here
02:26 PM robotustra: poking from time to time
02:53 PM Tom_L: you see the mill?
02:54 PM Tom_L: robotustra,
02:55 PM robotustra: not yet
02:56 PM Tom_L: https://www.youtube.com/watch?v=GtFTRyS__Yc
02:56 PM Tom_L: https://www.youtube.com/watch?v=rhw8fYyC3Jw
02:56 PM Tom_L: there's a couple for ya
02:56 PM robotustra: I'm still scraping my plates, may be 15% is done, moving slowly but surely
02:56 PM Tom_L: i'm cutting parts
02:57 PM robotustra: cool
02:58 PM Tom_L: https://www.youtube.com/watch?v=J6n2ZgY-5Ls&t=10s
02:58 PM robotustra: do you do 3mm depth cut?
02:58 PM Tom_L: probably half the tool width whatever tool i'm using
02:59 PM Tom_L: that one was probably .065" depth
02:59 PM Tom_L: .125 tool
02:59 PM robotustra: 1/8 you mean
02:59 PM Tom_L: yeah .125 :D
03:00 PM robotustra: what is the spindle power?
03:00 PM Tom_L: small
03:00 PM Tom_L: like .6 hp
03:00 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A9_2.jpg
03:00 PM Tom_L: that's the part
03:01 PM robotustra: oh, you have encoder to measure spindle turns?
03:01 PM Tom_L: yeah
03:01 PM AndrewGazelka: Hello, can someone explain (if simple) what an actuation space is? I cannot find any results to a definition on Google. :(
03:01 PM Tom_L: PID loop keeps speed constant
03:01 PM robotustra: ~constant
03:02 PM robotustra: nice job
03:02 PM robotustra: did you try to mill steel?
03:02 PM Tom_L: no not yet
03:02 PM Tom_L: i probably won't with that spindle
03:02 PM robotustra: and did you measure the precision?
03:03 PM Tom_L: close as the hair on a gnat's arse
03:04 PM robotustra: the hair is ~0.002" = 0.05mm
03:04 PM robotustra: fair
03:05 PM robotustra: I'm still waiting for 1.5" bolts to mount my t-slot table on the mill
03:05 PM robotustra: and I'm thinking how to make a drain system for coolant
03:06 PM robotustra: form big pan
03:06 PM Tom_L: i'm gonna mill a slot around my table and put a drain out the back
03:06 PM Tom_L: on one side
03:07 PM Tom_L: mine just fills the holes with coolant and then runs out the back
03:08 PM Tom_L: i might plug some of the holes with plastic stick or something until they're needed
03:08 PM Tom_L: but i'm not sorry i drilled em
03:08 PM Tom_L: i kept the pattern so i can predrill plates to fit them
03:09 PM Tom_L: also kept the coordinates so i can relocate to them if i ever need to
03:09 PM robotustra: how many hours a day you were you working on this mill?
03:09 PM Tom_L: evenings
03:09 PM robotustra: a week?
03:09 PM robotustra: 20?
03:09 PM robotustra: 40?
03:09 PM Tom_L: no idea
03:09 PM robotustra: about
03:10 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Column_Mill_VMC.jpg
03:10 PM Tom_L: what's the date on that pic?
03:10 PM Tom_L: that's a fair estimate
03:10 PM robotustra: I mean do you have normal work hours like 40h/w?
03:11 PM Tom_L: yeah i work daily
03:11 PM robotustra: good
03:12 PM robotustra: I also have only my evenings and weekends, but I'm getting lazy in the winter
03:12 PM robotustra: not working on lathe evety evening
03:12 PM robotustra: every*
03:14 PM robotustra: I mainly grinding metal on weekends
03:15 PM robotustra: hand scraping is during the working days if I
03:15 PM robotustra: if I'm not lazy
03:16 PM robotustra: got this pan to collect coolant https://www.ebay.com/itm/Fat-Daddios-Anodized-Aluminum-Sheet-Cake-Pan-3-Inch-High/281782537440
03:17 PM robotustra: 14"x22"
03:17 PM robotustra: 14"x22"x3"
03:18 PM robotustra: Tom_L, you have a garage?
03:21 PM robotustra: so you assembled this mill in 2 month?
03:24 PM Tom_L: garage yes
03:25 PM Tom_L: timeframe, i'm not sure but probably
03:25 PM Tom_L: i put my coolant in a gallon jug
03:25 PM robotustra: I did my first mill in 4 month about
03:25 PM Tom_L: i'll try to catch most of it back in some sort of pan once i get the slot milled
03:26 PM robotustra: and all other stuff arranged in 5-6 month after
03:28 PM robotustra: go home
03:32 PM -!- #robotics mode set to +o by cherryh.freenode.net
04:15 PM robotustra: Tom_L, what belt do you use for your spindle?
