Chinese 6040 stepper drives

[john swift]

yes your correct

the odd thing about these boards is the enable is a negative logic input
the board is enable with no input and disabled by a 5V enable signal !!!

the TB6560 CLK = YOC335 board PUL

TB6560 CW = YOC335 board DIR

connect the +5V wire (or wires) from the breakout board to the +CLK & +CW (positive clock & positive clockwise

the BOB's - PUL (negative pulse ) to the TB6560 - CLK (negative clock)

the BOB's - DIR (negative direction ) to the TB6560 - CW (negative clockwise)


without the data for the original drivers or motors we don't know what the motor current is

I would start with switches SW! to SW3 &S1 set to 1.5A
S2 for stop current 50%

if the torque is lower than with the YOC335 board increase the current in small increments and re test
if you set the current too high the motor will over heat

as we don't know the setting for the number of microsteps
try S3 &S4 set to 8 micro steps
if the axis moves too far set it to 16 micro stepps

you may need to make other adjustments in Mach3
