i have 2 Dmm servos on my y axis. I also have two home switches. I have the motors set with the Dmm software, tuned while not engaged to the rack. I verified the rotation and the homing switches activation. When I engage the racks, and try to home the system, the gantry moves ok for a short period and then seems to get out of alignment as if the servos are turning at different speeds. But I have confirmed that they are set to the same settings in the Dmm software. I have also had the direction of the one servo randomly reverse direction before ever getting to the stop. I have the y axis slaved to the B axis. I have even tried starting the home cycle and mannualy moving the gantry to the end to trigger the sensors before engaging the gear rack. Do you have any suggestions?.
