Hello all,
I am in the process of learning Mach3 to eventually build a small desktop engraver. Right now I have only gone so far as to set up 4 stepper motors and drivers (X, Y, Z and A) on my bench. The X, Y, and Z motors appear to be running normally. I can jog in the +/- direction and everything looks normal. I can enter Gcode and everything seems to look normal.
The problem that I am having is that my A axis rotates in the same direction regardless of the jog direction that I choose. MDI Gcode also shows rotations in the same direction regardless of the sign convention that I use (i.e. A-36 or A36).
I've checked my wiring several times. I have set the A axis as "Angular" in the general configuration file and I have made sure that I have the correct pins selected in the pin and port configuration.
Could anyone tell me if there is something else that I should look at in the setup? Also I am new at this so please let me know what more information that I can provide to help with an answer.
Any help would be greatly appreciated.
Thanks,
Randy
