Has anyone changed their firmware from Sailfish V7.8 (Qidi modified) to Sailfish V7.7 (official). My firmware acceleration control seems rather inconsistent, to the point where the carriage has moved to abruptly to cause stepper skipping (running at 90 for X and Y stepper current value). I know how to change the acceleration values in firmware, but am still noticing VERY choppy motion with very conservative numbers. I worry that Qidi messed with the firmware, and that things might improve by reverting to the official version. Anyone?
