Title: change of axis direction
Post by: Esprit on August 20, 2016, 03:57:00 AM

Go into Config. / Ports & Pins / Motor Outputs and change the Direction Low Active state for your X axis. This will reverse it's direction of travel.

X and Z axis travel the wrong way. Tried to do change this as above and yes have clicked accept but the travel direction does not change?

Any suggestions.

If you change the direction low active state for any axis it will change it's direction of travel (assuming the axis does in fact move in both directions).

Ah, if it does not move in both directions then you probably have either an open on one of the dir leads or an incorrect polarity between the dir + and dir -.  Since it can't sense the high/low state, it will always move in one direction only.  Once you get the wiring sorted out, then you can adjust correct direction with the Active Low option.

the axis all move in both directions. Have ro reverse only x and z axis.
Other thing is that ik i copy a drilling program the fastspeed moves to the product but the normal feed goes from the product..
have to have a good look at this...
