Steeper current adjustment?

[realtracks]

I just received the 3 axis stepper driver and it appears there is no current adjustment for the steppers. Does it have the ability to adjust current on the board?

I just received the 3 axis stepper driver and it appears there is no current adjustment for the steppers. Does it have the ability to adjust current on the board?

Formula: Vref/5Rs
Vrf = Voltage at pin#10
Rs= the current resistor (the bigger one you seem on the board, usually 2Watt)

Example:
1.0ohm = 1A
0.39ohm = 1.25A
0.3ohm = 1.5A

O.K. I expected it to be adjustable with a pot and vref like the rest of my drivers. My fault for not confirming before purchase. I did not expect to have to modify the board to adjust the stepper current.

Thanks for the reply
