I've got a PRTalpha upgrade, using the latest version 3.3.18. In determining the distance from the home(0,0) position to the activation point of either the X or Y axis proximity switch using the (K)eyboard control, the limit switch stops the carriage, BUT the readout goes on for another couple of inches. Then when I MH or JH it's off by the over run in the readout even though the steppers never actually went that distance to begin with...
I've checked the conections, the gears are snug on the steppers...
Any ideas????
