I did try two of four axis driver board TB6560, both chinese made, one is generic design. It is OK when running slow speed using in CNC router in Marh3, but using in the 3D printer, 20mm/sec will missing steps all the time. Another TB6560 board is custom made, running 45mm/sec sometime will getting same result. I using the Marlin firmware, try to change the stepper.cpp but no luck.
What I guess is the clock speed limitation. TB6560 is 15khz, THB6064 is 200khz. After I changed to THB6064, all problem gone, pls let me know if you can make it work.
