04:37 AM Tom_L: yours is listed there
04:37 AM Tom_L: Manufacturer Model Step Time Step Space Direction Hold Direction Setup Steps on
04:37 AM Tom_L: Xylotex XS-3525/8S-3 2000 1000 200 200 Rising Edge
07:53 AM Tom_L: https://hackaday.io/project/164332-prolight-1000-cnc-mill-retrofit/
08:06 AM Tom_L: if it's epoxy granite it should be a pretty nice machine
08:07 AM Tom_L: surely too nice for grbl :)
08:44 AM rue_mohr: this is cast iron...
08:45 AM rue_mohr: wait
08:45 AM rue_mohr: what
08:46 AM rue_mohr: its expoxy granite what
08:46 AM rue_mohr: what
08:46 AM Tom_L: you sure?
08:46 AM rue_mohr: no
08:47 AM rue_mohr: ...
08:47 AM rue_mohr: its hard when a knock-test gives you NO ring of any kind
08:47 AM rue_mohr: I didn't try a magnet
08:48 AM Tom_L: mebbe you should
08:49 AM rue_mohr: 8-| its not magnetic...
08:49 AM rue_mohr: wow, exotic
08:49 AM Tom_L: epoxy granite is pretty rigid
08:49 AM rue_mohr: yea
08:49 AM rue_mohr: and heavy
08:49 AM Tom_L: probably better than mine
08:50 AM rue_mohr: then it'll be super low resonanace
08:50 AM Tom_L: similar workspace
08:50 AM Tom_L: i got a little more here, you got a little more there
08:50 AM rue_mohr: I thoguht yours is larger
08:51 AM rue_mohr: wow
08:51 AM Tom_L: 17x13x7 and yours is 12.9x6.2x11.4
08:51 AM rue_mohr: k
08:51 AM Tom_L: more x
08:51 AM Tom_L: you got more z
08:51 AM Tom_L: which is good
08:51 AM rue_mohr: your vise fits just fine
08:52 AM Tom_L: it's limited but it works
08:52 AM rue_mohr: not working today
08:52 AM Tom_L: 4" shars
08:52 AM Tom_L: i have 1 job
08:52 AM rue_mohr: gonna take a morning nap :]
08:52 AM Tom_L: late morning
08:52 AM rue_mohr: educational machine makes sense
08:53 AM Tom_L: consider that 7i96s board
08:53 AM Tom_L: i think in the end you will forget the cost and be glad
08:53 AM rue_mohr: first priority is getting it a home in the shop
08:53 AM Tom_L: before it gets wet
08:53 AM rue_mohr: yea
08:53 AM rue_mohr: its been wet before from what I can tell
08:54 AM Tom_L: if it were me it would be inside already
08:54 AM rue_mohr: see how that goes
08:54 AM rue_mohr: yea
08:54 AM rue_mohr: its like 300-400lbs
08:54 AM Tom_L: i know
08:54 AM Tom_L: will/way
08:54 AM rue_mohr: and I dont have anywhere to put it
08:54 AM rue_mohr: (I'll make somewhere, will take a bit of time)
08:54 AM rue_mohr: not 3 months
08:55 AM Tom_L: what sort of slides does it have?
08:55 AM rue_mohr: I will probably boot the new mowerbot out for now and use that space
08:55 AM Tom_L: linear slides?
08:55 AM rue_mohr: linear bearings
08:55 AM rue_mohr: C
08:55 AM Tom_L: round rail or square?
08:55 AM rue_mohr: round
08:55 AM Tom_L: ok
08:55 AM rue_mohr: about 3/4"
08:55 AM Tom_L: i prefer the square but round is good
08:56 AM Tom_L: and ballscrews is nice too
08:56 AM rue_mohr: "That machine weighs a little less than 500 lbs"
08:56 AM rue_mohr: yea I need a table like that
08:57 AM Tom_L: does it have limit switches?
08:57 AM rue_mohr: whats that 2" tube?
08:57 AM rue_mohr: yes
08:57 AM Tom_L: probably 2" yes
08:57 AM Tom_L: he stole my paint color
08:57 AM rue_mohr: :)
08:58 AM rue_mohr: I dont think the spindle driver is that great
08:59 AM rue_mohr: at low speed I was able to stall it out by hand
08:59 AM Tom_L: linuxcnc
08:59 AM Tom_L: PID
08:59 AM Tom_L: i could too but not now
08:59 AM rue_mohr: surely I can do better than 2 band compensation
08:59 AM Tom_L: the sherline one was a bit slow to respond but it worked
09:00 AM rue_mohr: yea, I think this isn't as good as the sherline
09:00 AM rue_mohr: OR
09:00 AM Tom_L: it should be
09:00 AM rue_mohr: the brushes on the motor need ehlp
09:00 AM Tom_L: it's a bigger motor
09:00 AM Tom_L: 1hp?
09:00 AM rue_mohr: 1HP
09:00 AM Tom_L: compared to 600w
09:01 AM rue_mohr: I think it'll be a good thing
09:07 AM Tom_L: no doubt
09:07 AM Tom_L: get some vactra2 on the slides and table soon
09:08 AM Tom_L: or something comparable
09:50 AM rue_mohr: I oiled the table top
09:51 AM rue_mohr: it'll need a scour
09:51 AM Tom_L: do the linear bearings have an oiling system?
09:52 AM rue_mohr: not that I'v seen
09:53 AM Tom_L: grease zerks?
09:53 AM rue_mohr: not that I'v seen
10:29 AM rue_mohr: I kinda wonder what step rate grbl can get up to
10:36 AM aandrew: is epoxy granite granite powder with epoxy binder, or polished granite with epoxy coating?
12:17 PM rue_mohr: binder
12:17 PM rue_mohr: (as I understand)
12:22 PM Tom_L: epoxy with rock filler
02:25 PM rue_mohr: ok, I need to make shop space for that thing
02:45 PM rue_shop2: sleepy dehydrated
03:21 PM * Tom_L feels he could help rue_shop2 clear space for a mill really quick
04:26 PM polprog: finally home, back from Munchen
04:26 PM polprog: ill take a shower and go to sleep
04:27 PM Tom_L: wb
04:27 PM Tom_L: i hate long trips
05:35 PM rue_mohr: I'm going to evict the new mowerbot
05:35 PM rue_mohr: no space to work on it in here anyhow
05:36 PM rue_mohr: the cnc is about the same size and I can keep it dry and buy time to figure out how the hell to put it on a bench
05:36 PM rue_mohr: I'm pondering a bench that sits just over the existing one
05:36 PM rue_mohr: but
05:36 PM rue_mohr: I think it'll come out too high, so
05:37 PM rue_mohr: the other option is to put a steel bench *just under* the wood one
09:51 PM rue_shop3: so, here I go again
09:52 PM rue_shop3: I need to weld a frame, thats flat
09:59 PM Tom_L: sounds like a simple task
10:01 PM rue_shop3: on uneven dirt
10:05 PM Tom_L: level & shims
10:05 PM rue_mohr: ah level...
10:05 PM rue_mohr: huh
10:06 PM rue_mohr: I should make some little motorized leveler feets
10:06 PM rue_mohr: I'd have used them a few times now
10:13 PM rue_mohr: material for bucking up under the table where the cnc will go
10:14 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1280903.jpg
10:16 PM Tom_L: you're gonna want some good 2" square tube
10:16 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1280891.jpg
10:16 PM rue_mohr: no
10:16 PM Tom_L: not just to support it but when it's moving it will wiggle around too
10:16 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1280905.jpg
10:16 PM rue_mohr: ah, last image
10:16 PM Tom_L: maybe a bit thin
10:16 PM rue_mohr: its apparently rated for 600lbs over 4 feet
10:16 PM Tom_L: be careful welding galvanized
10:16 PM rue_mohr: yea
10:17 PM rue_mohr: that was going to be my comment
10:17 PM Tom_L: it's nasty stuff
10:17 PM rue_mohr: do not inhale while welding
10:17 PM rue_mohr: make sure there is a breeze
10:17 PM rue_mohr: and even better, wear the repirator
10:18 PM rue_mohr: so, what do ya think of the new paint job on the trike?
10:18 PM rue_mohr: looks less like welded up scrap eh?
10:18 PM Tom_L: yeah that looks better
10:19 PM Tom_L: what's the cnc sitting on now?
10:19 PM rue_mohr: a lower frame for a hospital bed
10:19 PM rue_mohr: the same one I used to move/lift the lathe
10:20 PM rue_mohr: if I make new tools every time I do stupid stuff like this, it'll get easier as I go
10:23 PM Tom_L: you're just collecting a good set of tools
10:24 PM rue_mohr: :)
10:24 PM Tom_L: did you get collets with it?
10:24 PM rue_mohr: I'm learning a lot of cool things latley
10:25 PM rue_mohr: NO
10:25 PM Tom_L: like what?
10:25 PM rue_mohr: apparenltly it seems to have not had any
10:25 PM rue_mohr: well, one
10:25 PM rue_mohr: 3/8"
10:26 PM rue_mohr: they are R8, my machining buddy says thats the one to have, super popular
10:26 PM Tom_L: bridgeport are R8
10:26 PM rue_mohr: so
10:26 PM Tom_L: not the handiest but common
10:26 PM rue_mohr: there were two other tool heads there
10:27 PM rue_mohr: but they were for a cnc with an autochanger
10:27 PM rue_mohr: the angle of the taper looked similar
10:27 PM rue_mohr: but
10:27 PM rue_mohr: they didn't have any "normal" tool ends
10:28 PM rue_mohr: I'm not sure what they were for
10:28 PM Tom_L: retention knobs
10:28 PM rue_mohr: "nothing I'll ever use"
10:28 PM Tom_L: threaded end
10:28 PM rue_mohr: yep
10:28 PM rue_mohr: knob end
10:28 PM Tom_L: that would be a nice thing to have
10:28 PM rue_mohr: no tool cahnger
10:28 PM rue_mohr: and thats not for this machine
10:28 PM Tom_L: maybe bt30 or something
10:28 PM rue_mohr: and they didn't have any normal/usable tool ends
10:30 PM Tom_L: should have grabbed pics
10:32 PM rue_mohr: yea, sorry...
10:32 PM rue_mohr: I was super distracted cause they has sold the big router and were working on moving it out
10:32 PM rue_mohr: I was happy it got a home and curious as to who, but he didn't come thru as friendly and I didn't want to be rude
