12:08 AM rue_shop1: I found a way to counter it, I used a scented candle for the wax
12:12 AM rue_shop1: its melting now, total volume 20g
12:15 AM rue_shop1: the loop controller needs work, its got some overshoot (125c of 110c)
12:28 AM rue_shop1: hmm
12:28 AM rue_shop1: at about 130c the lining of the catfood can starts to shrink
01:19 AM rue_shop3: ssh -q -X user@sixtyfour.rueshouse.net
01:44 AM rue_shop3: ok, lets focus on using SDL to load a jpg and do a diff against another jpg
06:30 AM Tom_L: rue_shop3 is collecting metal bricks to build his new house
06:31 AM Tom_L: wonder how long an all aluminum house would last
06:32 AM rue_mohr: isn't it kinda early for you to be up?
06:33 AM Tom_L: no i generally get up an hour ago or more
06:33 AM rue_mohr: 4:30am
06:34 AM rue_mohr: 6:30 tere?
06:34 AM Tom_L: sounds right
06:34 AM rue_mohr: playing with rewriting clipper
06:35 AM rue_mohr: (poly clipping library)
06:35 AM Tom_L: https://www.aliexpress.com/store/product/5pcs-NEMA17-78-Oz-in-CNC-stepper-motor-stepping-motor-1-8A/704350_554160664.html
06:35 AM Tom_L: those are a little cheaper but a little smaller
06:35 AM Tom_L: but inline with his price
06:36 AM rue_mohr: generally the motors have been a pretty expensive part
06:36 AM rue_mohr: I got enough for a lot more printers
06:36 AM Tom_L: i'm used to buying nema 23 so they seem not that expensive
06:36 AM rue_mohr: heh
06:37 AM Tom_L: especially in the 500+ oz in range
06:37 AM rue_mohr: so, this summer I'll make it a project to build a 4x8 router
06:37 AM rue_mohr: lean it up
06:38 AM Tom_L: use belts
06:38 AM Tom_L: screws will whip too much
06:38 AM rue_mohr: w/steel?
06:38 AM rue_mohr: iirc there are belts w/ steel in them to bring down the stretch
06:38 AM Tom_L: or figure another way to use screws
06:38 AM rue_mohr: not too into screws
06:39 AM Tom_L: kevlar or steel maybe
06:39 AM rue_mohr: chain seems to suck for linearity
06:39 AM rue_mohr: rack & pinion
06:40 AM rue_mohr: just a few inches z
06:41 AM Tom_L: you say that...
06:41 AM Tom_L: you will want more
06:41 AM rue_mohr: na, its a 4'x8' router
06:41 AM rue_mohr: its in the *load a sheet of plywood and make big shapes* catagory
06:42 AM Tom_L: build it to be a plasma too then
06:42 AM rue_mohr: hahah no
06:42 AM rue_mohr: inclined
06:42 AM Tom_L: yes
06:42 AM rue_mohr: at line 78 degrees
06:42 AM Tom_L: will work the same
06:42 AM Tom_L: why?
06:42 AM rue_mohr: space
06:42 AM rue_mohr: I have to put it up against the house under the eave
06:43 AM Tom_L: time for a new addition
06:43 AM rue_mohr: I can prolly take it to a footprint of like 2x9'
06:44 AM Tom_L: just remember you need an extra foot or so for whatever you put in it
06:44 AM rue_mohr: thats why I say 9
06:44 AM Tom_L: so if a 4 x 8 sheet you need 5 x 9
06:44 AM rue_mohr: maybe 10, I'v blown that on every machine so far
06:45 AM Tom_L: just depends on the design
06:45 AM rue_mohr: moving gantry, xyz
06:46 AM Tom_L: just like a plasma :)
06:46 AM * rue_mohr rolls eyes
06:46 AM rue_mohr: a) I dont have a torch, b) I dont have anywhere to put it that can deal with the fire
06:46 AM rue_mohr: c) I dont want to have to make it fireproof
06:47 AM rue_mohr: plasma cuts are usually horrid anyhow
06:47 AM Tom_L: you'd be able to make so many more parts for your mech...
06:47 AM rue_mohr: I have access to a waterjet, not into plasma
06:47 AM rue_mohr: hah
06:47 AM rue_mohr: its not made out of lots of plate
06:48 AM rue_mohr: I havn't even done anything with the waterjet I have access to
06:48 AM rue_mohr: :/
06:49 AM rue_mohr: they apparently dissassembled it to make the warehouse bigger
06:49 AM Tom_L: they don't cut perpendicular either
06:49 AM rue_mohr: no, kind a V
06:49 AM rue_mohr: upside down...
06:49 AM Tom_L: yeah a little undercut
06:49 AM rue_mohr: but a plasma, from what I know, isn't straight anyhow
06:49 AM Tom_L: but for sheet it generally doesn't matter
06:49 AM rue_mohr: and comes with hardened edges
06:51 AM rue_mohr: ok, I'm gonna try to sleep again

03:13 PM rue_mohr: somehow I expected that
03:18 PM rue_mohr: looks like someone used 4100V on something meant for 480
03:18 PM rue_mohr: and skipped the fuses
04:59 PM Tom_itx: been a rather non productive day
