I am an official purchaser of Mach 3 software.
I bought a Chinese kit to put together a WorkBee 1500 x 1500 lead screw machine. It has a Novusun controller and TB6600 stepper controllers driving the 3A, 8 microstep stepper motors.
I also purchased V-Carve Pro because I had some very specific artwork with fonts in my house I wanted to copy and reproduce on wood for my grandchildren's bunkbeds.
Anyway, I think I have the settings correct in Mach 3 (settings that worked for others), but I'm not sure this system is compatible with things created with V-Carve Pro and the .txt files they make for G-code. Z axis goes too far up, and too far down.
I'm to the point where I'm ready to try another main controller and stepper controllers for these motors that others KNOW can work with V-Carve Pro .txt files and Mach 3.
Any suggestions?
