I see there are examples of the controller providing signal to each of the drivers, im just wondering if i am likely to encounter any problems with the gantry running out of tram using this method? I plan to use the AM882 drivers.
Provided you don't crash the machine and cause one axis to stall and twist the gantry, then it's not likely to be a problem. You just need to ensure you have some method to re-align the gantry if you do. If it was me, I'd probably just setup some accurate endstops at one end, and slowly run the gantry into them to square it up again. Then re-home it to regain position.
