[11:52:10] <skunkworks> jthornton: it is a monoprice mini v2
[11:52:33] <skunkworks> as much as I have used it - I am happy with it.
[11:57:13] <skunkworks> I bought it to get my feet wet...

[18:03:38] <Tom_L> loading and running 2.8 on the mill was a fail
[18:04:13] <Tom_L> installed and upgraded fine, ran the config, started up fine, homed fine, just sat there when trying to run a program
[18:04:45] <Tom_L> loaded up 2.7 and cut the part
[18:06:02] <Tom_L> it acted like the program was running but the feed was off and stuck on one line
[18:07:01] <Tom_L> not very specific help i know but wanted to voice it at least
[18:30:42] <andypugh> spindle.0.at-speed not connected?
[18:31:15] <Tom_L> i didn't investigate much, was trying to get the part done
[18:31:35] <Tom_L> i will go back and look later on
[18:32:00] <Tom_L> nothing changed except the ssd from 2.7 to 2.8. same config copied over
[18:32:13] <Tom_L> then converted
[18:37:44] <andypugh> I _think_ I tested spindle-at speed with MultiSpindle
[18:39:04] <Tom_L> i'm using at speed but i honestly don't remember if the spindle came on or not
[18:39:33] <Tom_L> i think it may have been on a linear move but i'd want to re'test it for sure
[18:39:58] <andypugh> Linear moves pause waiting for spindle-at-speed
[18:40:07] <Tom_L> hmm
[18:40:41] <Tom_L> did you see the threads i cut with the sherline spindle?
[18:40:52] <andypugh> No
[18:41:15] <Tom_L> http://tom-itx.no-ip.biz:81
[18:43:42] <Tom_L> https://www.youtube.com
[18:45:45] <Tom_L> been told i'm running it way too slow
[18:46:44] <andypugh> Doesn’t look slow to me.
[18:46:51] <andypugh> But what do I know?
[18:46:59] <Tom_L> more than me
[18:47:45] <Tom_L> says it's 467 sfm
[18:51:36] <andypugh> HSS or carbide?
[18:52:51] <Tom_L> carbide
[18:56:02] <andypugh> 140m/min
[18:56:27] <andypugh> Faster than I normally run, but then I have a really rather slow spindle.
[18:56:32] <Tom_L> i'm gonna bump up the rpm for sure but this was the first off part
[18:57:24] <Tom_L> it calculated a .0004" chip load which i probably could increase too
[18:57:28] <andypugh> What diameter? If it’s 1” then that SFM is about 900rpm
[18:57:48] <Tom_L> the thread is 3/4 16 and the cutter is .595"
[18:57:49] <andypugh> And it looked like about that
[18:58:11] <Tom_L> the cad cam tells me the SFM
[18:58:11] <andypugh> OK, so 1800rpm then
[18:58:19] <Tom_L> 3000
[18:59:09] <andypugh> Ah, yes, I had a spurious 2 in there
[18:59:13] <Tom_L> probably will bump it to 4000
[18:59:18] <Tom_L> 6 flute
[19:00:42] <Tom_L> lcvette tends to run his stuff pretty fast though and he's the one that said it's way to slow
[19:01:29] <Tom_L> https://www.youtube.com
[19:01:32] <Tom_L> check his out
[19:01:56] <Tom_L> somewhere past 1 min in
[19:02:26] <Tom_L> steel i think he said
[19:02:29] <Tom_L> 'iron'
[19:04:04] <andypugh> That’s a rather smaller thread-mill though
[19:05:44] <Tom_L> still seems fast
[19:06:40] <andypugh> Yes, I agree.
[19:07:07] <andypugh> It was instructve to walk around MPM. The spindle and cutting speeds there all seemeed very modest compared to YouTube demos.
[19:07:17] <Tom_L> if i were after production runs i'd worry
[19:07:27] <Tom_L> yeah
[19:07:30] <andypugh> MPM were production...
[19:07:38] <Tom_L> yeah i know
[19:08:29] <Tom_L> most mfg demos push their stuff to the max
[19:09:46] <Tom_L> first part i started out nominal on the PD and added .002" for clearance on the 2nd try and it fit nice and snug on the spindle
[19:10:40] * Tom_L just realized he's in devel...
