General Mach Discussion / Re: Dirty jittery movement on one axis

HYU…
Dongguan Hungyu manufacture various stepper driver boards which are then marketed by other distributors etc under different names so it is difficult to identify which one you actually have.
As far as I am aware they all use either the Toshiba TA8435H or the Toshiba TB6560HQ driver chips and you need to identify which of these you have fitted.
Replacement chips are available from many different sources / suppliers but I would suggest an ebay search for the best price.
(Interesting that you are using 2 stepper motors for each of the 3 axes. As a general rule, it is not considered good practice to connect more than one stepper motor to each axis output from any driver board although I understand that it can be done).
Hope this helps.
