That's a seriously nice vice!
Here's the PM-30 steel base on the completed Grizzly mobile base. It seems pretty stable even when I get up and stand on top. You need to adjust the height of the deployable rubber feet carefully so that the base is close to level when they are deployed. It doesn't have to be perfect, the floor is not totally flat anyway and fine tuning will have to be done at the final location.

@gregreid It isn't 11 years, that was 2020! I posted it here because its main purpose at the time was to make rocket parts and I don't have a presence on any machining forums I basically spent most of 2019 building it.
I've made some upgrades lately - split out the digital electronics into a 2nd Wiegmann cabinet, built up a breadboard with a Centroid Acorn controller (planning to ditch Mach4, it's totally unsafe with probes), fixed the janky way I originally made the cover plates for the power hydra, got some great tooling, and other stuff that I've forgotten already. I really need to do some updates to this thread.
Good look on your PM-30MV conversion!! I hope Dave at ArizonaVideos is still making those great ballscrew conversion kits.
The issue I had with Mach4 probe macros (and I found other references out there about it) is that it would sometimes make a sudden unconstrained downward rapid movement. I've had it happen twice and except for a piece of good luck I would have broken my KP-3 probe already. This is some kind of bug in the software. Also Mach4 has no provisions for limiting probe movement based on a hardware probe detect input like Acorn does. Mach3 is a completely different piece of software; Mach4 was an attempt at a rewrite but it has never really settled down to a stable release as well as Mach3 did. I'd recommend looking at Acorn or LinuxCNC for new projects, or continuing with Mach3 if they are still selling licenses.Interesting observation on Mach4. My CNC router (wood, not metal) seemed to be pretty decent with Mach3. What specifically is the bugaboo with Mach4 and probes or is it just the fact that your machine is more heavy duty compared to CNC routers? Just curious as I was considering a project that would have likely used Mach4! I might need to reconsider!
