Need Help!- Current setting for TB6560 3-axis board (eBay)

[leaveme]

I just have my 3-axis board from eBay ( ) in hand. The chipset is TB6560. I will be using this board for my mini cnc router. Lowest current setting for this board is 1.5A (using dip switches).

Unfortunately my steppers are 1A and I have to set it in the board. The board shipped with 0.22 ohm registor (red-red-silver-gold), which you can see from the image. It has a DIP switch for current setting but I think I need to replace the registors for having lower current setting (1A).

Somebody having knowledge on this board please advice.

By the way, I also attached the config doc, which I received from the seller.


Thank you in advance.

.5 ohm resistor for 1 amp output.

Hi JoeyB,

Thank you for yor help.
Do you mind to share the calculation...I mean the way you calculated it.
Also appreciate your opinion about the dip switch setting.

Dip settings are like this:
current - sw1-sw2
------------------
100%----on---on
75%-----on---off
50%-----off---on
25%-----off---off

I suppose my setting will be 50% for .5 ohm. Am I right?

regards

According to the TB6560 spec sheet the current at 100% is 0.5/Resitance. For 0.22 resistors this is .5/.22 = 2.27 amps.
