Use the stallguard feature to figure out max. acceleration?
-
Having read up the on the Stallguard feature of the TMC2660 drivers, wonder if there's a way to make use of it.
In particular, how about a test routine which performs a series of increasingly rapid accelerations on the various axes?
The objective would be to monitor the output from the Stallguard, perhaps to determine what acceleration demands 80% of maximum torque of each motor (the masses, frictions, leverages etc associated with each axis are going to be different).
These figures might then inform the selection of acceleration parameters for the 3d printer in question.
