Hi All,  when I press goto zero my X axis sets to 0.0025. This seems to shift the whole cut in the X direction. I am cutting a mold and the cuts are all in the same direction (left to right) After each cut the X axis is returned to 0 and the y axis increments a tiny amount and the next cut is moved to the right a small amount. This is not a gcode action. If I jog x about 120 mm then goto zero the x axis returns perfectly but the dro shows x at 0.0025? Weird! Any suggestions?

what is your steps/per Setting on this axis?
witch Units are you in (imperial/mm)?

I found that My connections to the gecko's caused the loss of position. I was using ground as the common and should have set the dir signal to active high. I still have to check the 0.0025 thing on the goto zero but I suspect that that was also the cause. The steps per mm are around 400 and change. Thanks for your interest
