Hi, I've setup a few different machines (routers/grinders) using Mach3 with steppers and Gecko G540 drives, servos with CNC TekniX Drives with great success.
But recently I setup a grinding machine with C32 Breakout Board, 1200oz/in steppers and G201x drivers set to 6amps and a 48v power supply.
For the most part it seems to work but when jogging the motors jerk every so often, it's very similar to a servo motor having a very large positional error set, then losing position and catching up.
Any ideas why it might have this type of behaviour.
BTW does it matter if we use a switching power supply rather than a linear power supply?
