Preliminary tests on my desktop test unit were successful. I have a project to finish on my rose engine before I can fully test it. Thank you very much for this.

No, the stepper/controller interface is different. The Path Following routine here is the T3.5/3.6 version.

This sketch shows one of the main issues with T4.1. Typical step rates are under 30,000/sec. Microsteps are usually set to 32 with a few machines using 16. 99.9% of the routines will use four or fewer steppers synchronously.
