Alrighty, got my little CNC router running. The control I bought (DDCSV3.1) is lacking and I need to get linuxcnc onto it. Waiting for appropriate mesa boards to be in stock.

It doesn't do too bad under the cheap control, but it has no constant velocity (g64) mode and I've had to reduce the acceleration. It also has no real expandable functions.

I am also trying to refine the tuning of the servos a little more. The x and y do well enough, the Z lags 5-10 pulses behind when moving upward. Anyone have these servos and have any tuning advice?



Zoom. 7500mm/m (295ipm) when the control can keep up.

Yeah I had to make my own cause I have a 50mm bolt spacing, and also the shipping was more than the vise!!!!

I was worried the machine wasn't precise enough to make them, but, its just fine. In the longer term I will make the bases and hard jaws from 4140HT, however the price right now for that is offensive haha, $350ish for 2 vises worth.

This is the eventual layout. I also have a vacuum table.
