04:47 AM t4nk_freenode: argh... I desperately want to make some kind of hand saw guide before I do anything else :|
04:47 AM t4nk_freenode: hi Deejay btw ;)
04:47 AM Deejay: hi t4nk_freenode
04:48 AM t4nk_freenode: I got two of these boxes, don't know how you call them, to make straight and angled cuts, like 90 and 45 degrees
04:48 AM t4nk_freenode: but they're just too small
04:48 AM t4nk_freenode: and not all that great either if you ask me
04:49 AM t4nk_freenode: but I just about had enough of making crooked cuts
04:49 AM XXCoder: isnt there saw guide box in stores
04:49 AM XXCoder: tho for wood
04:50 AM t4nk_freenode: I think that's what I refered to, .. let me have a look.. https://static.gamma.nl/dam/34918/123
04:50 AM t4nk_freenode: sth like that
04:51 AM t4nk_freenode: but they're probably about 12 or 15cms wide.. that's too small
04:51 AM t4nk_freenode: or deep that is
04:52 AM JT-Cave: morning
04:52 AM t4nk_freenode: morning
04:53 AM XXCoder: heys
05:47 AM louipc: t4nk_freenode: miter box
05:48 AM t4nk_freenode: yeah, that's the term, louipc ... but mine is 9cm's wide, can't really cut anything bigger than that
05:49 AM t4nk_freenode: and most of them are like that, though some might be slightly bigger
05:50 AM t4nk_freenode: but I just found some magnets, and some fat wooden square legs
05:50 AM louipc: i guess pp just use miter saws now
05:51 AM t4nk_freenode: I'm gonna fit the magnets to the leg, clamp that down onto some base... and some other wood to guide... maybe it'll work
05:51 AM t4nk_freenode: yeah, darnit, I'd like some power tools too... but I aint got the room here, let alone the horrible noise ;)
05:52 AM louipc: i like the noise. especially "cha-ching, cha-ching"
05:53 AM t4nk_freenode: I can buy pieces of wood, 1m22x66cm or so... I guess I can saw those with the stuff I just described
05:54 AM t4nk_freenode: most cuts would be a lot smaller though, but I need to cut the plates up too
05:54 AM louipc: you can just lay it out with square, protractor, whatever
05:54 AM louipc: or make a bigger box if you really wanted..
05:55 AM t4nk_freenode: yeah, because the square and prothingy you mention... lol.. that's the whole problem.. I KNOW how I would like to saw... lol, but without a guide.. I'm as lousy as it gets
05:56 AM t4nk_freenode: it's gotten a bit better of late though, but I can't stand the uncertainty
05:57 AM t4nk_freenode: I printed some corners to connect 4mm mdf into boxes... they work like a charm, but now I want to saw a whole bunch of mdf to size, and don't want to worry about going crooked
05:58 AM t4nk_freenode: but I can tape down the magnets to the side of the fat leg, and clamp the rest, so this tryout won't mess up my materials
06:09 AM Tom_L: morning
06:10 AM XXCoder: yo

09:03 AM jymmmm: morning
11:28 AM JT-Shop: hmm, my cylinder rebuild kits are on the way
11:49 AM Tom_L: cylinders for what?
11:49 AM Tom_L: oh the tractor?
12:01 PM JT-Shop: yea, might as well rebuild them all the bucket cylinders leak past the piston
12:05 PM JT-Shop: features too far apart so best is to redesign them so I can machine them in one setup lol
03:23 PM Deejay: gn8
03:24 PM louipc: nite
05:16 PM _unreal_: sup
05:16 PM _unreal_: pcw_home, you live?
05:17 PM _unreal_: or anyone who knows. if you have a choice between a DC/DC psu for input V to 5v output. OR a 7805. which would you choose for the 7i96 for a 5v supply?
05:17 PM _unreal_: the 5v supply is only driving the 7i96
05:19 PM pcw_home: Either will work. Linear is probably more trustworthy and a 7I96 will only draw about 200 mA
05:20 PM _unreal_: ok 7805 it is
05:20 PM _unreal_: also tonight I need to start rigging all the wires up. I have my immediat wire harness setup to drive the motor controllers
05:21 PM _unreal_: so it should be nothing more then plugging in
05:21 PM _unreal_: I'll be pining ya about mesa setup tonight or soon
05:41 PM Tom_L: _unreal_, i use a smps
05:41 PM Tom_L: 7805 will get too hot probably
05:42 PM Tom_L: if you try to drop the voltage too much
05:42 PM _unreal_: heat isnt an issue
05:42 PM Tom_L: heat sink it then
05:43 PM Tom_L: 7805 with a cap on each side of it
05:51 PM _unreal_: Tom_L, thats the plan
05:55 PM -!- #linuxcnc mode set to +v by ChanServ
05:57 PM -!- #linuxcnc mode set to +v by ChanServ
06:06 PM _unreal_: I cant find my 7805's so I'm going witht he DC/DC
06:06 PM _unreal_: have a brand new package but I've lost em
06:45 PM _unreal_: ok the hard part is done. all the major wiring has been put together.
06:45 PM _unreal_: still need to mount the mesa board into the motor driver box
06:46 PM _unreal_: but at least when I get to that part its for the most part just plugging sockets in

08:19 PM skunkworks: https://youtu.be/nzI0_iZ4cgo
08:27 PM Tom_L: :)
08:28 PM Tom_L: wish i had one to cut these keyways
08:29 PM robotustra: I constantly thinking of make some small shaper
08:29 PM robotustra: and push this idea far away
08:29 PM robotustra: from my brain
08:57 PM _unreal_: well time to start mounting hardware
09:00 PM _unreal_: who's around?
09:00 PM _unreal_: so I have 400oz/in 1.8 degree steppers. they run at 3amps 36v.
09:01 PM _unreal_: what micro stepping rate would you guys suggest at the max?
09:01 PM _unreal_: my motor controllers can go as high as 1/128
09:01 PM _unreal_: currently have it set to 1/16th
09:05 PM skunkworks: Tom_L: hasn't been run in years
09:05 PM Tom_L: guess you'll have to find jobs for it now
09:05 PM skunkworks: heh - maybe
09:06 PM Tom_L: _unreal_, my geckos are set at 10
09:08 PM _unreal_: 10?
09:09 PM _unreal_: oh 1/10th?
09:10 PM _unreal_: My controller does 1/8, 1/10, 1/16th, 1/20, 1/32, 1/64, 1/128
09:11 PM Tom_L: yeah the geckos are preset at 10
09:11 PM Tom_L: they may adjust it internally i dunno
09:12 PM Tom_L: try 1/10. seems to work pretty well with the geckos
09:14 PM _unreal_: I'm sure any value will work for my setup
09:14 PM _unreal_: I'm just wondering if there is a reasonable and un reasonable micro stepping range
09:14 PM Tom_L: i'm sure there is
09:15 PM Tom_L: i haven't experimented with microstepping
09:17 PM _unreal_: interesting https://hackaday.com/2016/08/29/how-accurate-is-microstepping-really/
09:18 PM Tom_L: i was looking for a similar article
09:20 PM Tom_L: the holding torque goes down the higher the microsteps
09:20 PM snakedGT is now known as snaked
09:26 PM _unreal_: who knows maybe I'll go with 1/8th then
09:26 PM skunkworks: I would just set it high enough that you don't get resonence..
09:26 PM _unreal_: get as much torque as I can
09:27 PM _unreal_: till I get it running I wont know
09:27 PM _unreal_: and there is no reall good access to the motor controllers once I put the motion controller into place in the current box seup I have :(
09:27 PM _unreal_: oh well
09:28 PM skunkworks: 10 is probably a good starting point
09:29 PM Tom_L: that's one thing on the geckos you don't have to worry about
09:30 PM skunkworks: most of my stuff runs 1000 steps per rev.
09:32 PM Tom_L: ok, early day tomorrow. gnite
10:02 PM Thorhian: My new shaft coupler for my Z axis came today. Dang it's way bigger than my current one XD
10:04 PM Thorhian: Also, _unreal_, are you modifying your current machine or building something new?
