Which HobbyCnc driver board is better the 3 axis or the 4 axis pro my machine only has 3 axis but wanted to know if there is any difference between the 2 board other than the extra axis and are this boards better than the TB6560 any reply or help will be appreciated
Isn't hobbycnc a kit that needs to be soldered together? It's not as easy to destroy once everything is soldered together. But it is only for unipolar and 8 wire motors. It will not work with 4 wire motors.
In terms of performance, there is no blanket answer. It really depends on your motors and system. But they have similar specs.
Any replies will be appreciated are they atleast better than the tb6560
The HobbyCNC kits that I have seen use the larger SLA type stepper driver chips, they are much more rugged, much larger silicon die and better at heat dissipation than the small surface-mount chips used in the TB6560.
The SLA series actually works at 3 Amps safely and continuously in an industrial type machine, the TB6560 at 3A is pushing its limits real hard and won't last in an industrial type setting. The SLA is a proper large motor driver, the TB6560 is more for little bubblejet printer motors etc although people try to use them on CNC machines.
