I use the A stepper motor on my lathe ATC to turn the 8 tool turret.
Tool no 1 is set to 0, tool no 2 is set to 25.5 etc. Everything works well if i go from tool 1 to tool 2 until tool tool 8. Then problem starts when going back to tool 1, the turret continue the same direction, not in reverse. After the tools will not end up where it should.
It is Mach3 turn with paralell port. X and Z axis works well.
What have I done wrong?
