Lots of stuff going on... I made a new sub-table to mount my t-slot table to, since of course the arbitrarily-pitched hole pattern I drilled on the previous one was completely incompatible with the table. Serves me right, I'm sure.
Anyway, I made that, mounted it, and machined it flat.
...And mounted the t-slot table on top of it:
And here everything is sitting in my shop... I got a new workbench to put things on, so it's a little less cluttered.
It was a bit of a trip getting here. I blew up my nice Geckodrives- really not sure how, but they tell me I totally fried basically everything, from a FET or two down through the entire 3V3 bus. On all of them. At the same time. I have no idea how that happened- best they can guess is a ground loop. So now I've joined the Beaglebone and the stepper PSU grounds. Haven't blown up the new drives yet!
The new drives are an all-in-one unit from Geckodrive- the G540. It even has a drive for a fourth axis! What's nice is that the pinout matches that of the Beaglebone almost exactly- I only had to remap one pin. No idea if that's intentional or not. It's ALSO good that I had the forethought to wire my steppers to DB9 connectors in the standard Geckodrive pinout, so they dropped right in with the new drives. It's like I KNEW I'd blow things up or something... mostly serendipity actually, though I'm not going to complain.
I ALSO blew up the Beaglebone. Again, not sure how. I was probing pins at the time (trying to get the new drives configured), so I probably shorted something out. Normally electronics don't straight up die from a brief short, but that's all I can figure. One of the 3V3 rails is trashed, and there's enough stuff on said rail that I didn't want to dig. Plus the regulator is a large-ish QFN in an inconvenient place, so I didn't want to replace it on the off chance it's the problem.
Anyway... ready to get back to breaking end mills! And to stop slacking on that laptop...
