I upgraded my 3018 CNC using 3 TB6600 stepper motor drivers because they are cheap and the current rating seemed good (more than enough for any nema 17 motors).
I started noticing some drifting during some long milling jobs. The drifting showed more clearly in the X and Y axis (cannot really tell in the Z axis).
This problem didn't occur when I used the same stepper motors with the original stepper motors on the original board of the machine (very small and not powerful).
I decided to swap the TB6600 with 3 of the DM542 stepper motor driver. They are bigger, more expensive but they worked as expected. The drifting disappeared after the change.
So, please stay away from the TB6600 stepper motor drivers. They are cheap but you get what you pay for - problems!!!
