Hi!
I used home made drivers, which I changed for TB6600 and I got a problem, which I don't have on my home made ones. The function of the motor is: go to 175 steps, -75 steps and -100 steps. when it goes from position 100 to 0 it sometimes stops ( makes 1-5 steps only, instead of 100).
I use arduino due to send signals, they are 3.3V. The TB6600 is powerd with 12V from computer PSU.
It is this one Single Axis TB6600 0 2 5A CNC Engraving Machine Stepper Motor Driver Controller | eBay

how to solve the problem? Is the table or DIP switch fixed or still wrong?
