New Machine, calibrated and leveled. Arm drives too far at touch off and pushes the arm up. Any way to change settings easily?
Thanks
My first thought would be to check the Z axis cable to make sure it is seated properly at both ends. This is what tells the Arcdroid Z axis where it is and if not seated properly could be you issue. If I understand you problem correctly.
I think it is the normal operation of the machine. I was worried about it as well. But after looking at the setup. The z switch is at the cable end on the main unit. So it drives the z down until you get slack in the cable and past that point just a bit so that when it retracts it can get an exact position that the cable gets tight and activates the z switch so the deflection of the arm is the springs pushing it up when there is slack in the cable. They compensate for this in the default Z offset. so it knows to add say 0.040 to the position for the arm deflection. Again I was very concerned when I first started using the unit with how much the arm moves up and down when probing. but it makes great cuts if the table is level with the unit.
