I’m working on a Unistream application using UID-0808THS modules to control stepper motors on an XY table. I have the moves working and the machine sequences through the preset positions but I have an issue with homing.
The homing function woks fine, when initiated to set the current position to zero, or whatever offset is used, but I need someway to move the motors to a position that is the home position, or an offset from the home position, before initiating the home function.
This could be a programmed sequence that goes to a switch input, or a manual jog type function that would allow the operator to move the table manually and then set the home position when it is in the correct position. I can’t find any way to get the motors to move other than the relative or absolute moves on the PTO Move function.
Any help or suggestions would be appreciated.
Thanks,
Mark
