I’m using a dual gantry for a measurement system which will not have a fixed base (literally can slide around on top of a table) and is designed to be partly disassembled, shipped and reassembled on occasion. This means the two motors may easily come out of sync and I’m looking for a way to have the system automatically reset the base back to square periodically. Since it appears that the XYZA limit switches are independent of the actual motor running, it seems plausible that I can use four inputs for a ‘Limit/Home’ switch.
Based on the documentation, it sounds like I won’t be able to do this under an XYYZ configuration and will have to implement the two independent Y motors as an XYZA configuration. Is this a correct assumption?
In short, I’d have to configure the controller (for example, set the two Y motors temporarily as X and Y), and then set home the two Y motors (e.g. G28 X Y). Then completely reconfigure the controller for the normal setup as XYYZ.
Is there a better way to do this, or am I on the right track?
