Oh well it looks like I will not get unto next week now.

I have been reading the so called bad english manual for the driver board to work out what DIP Switch settings I am going to need.

I am only intrested in switches 1-4.

Switches 1-2 are for the current setting, 100%, 75%, 50%, 25%.

Is this a case of 3.00amps, 2.25amps, 1.50amps, 0.70amps, or does the board self sence the current and when at idle or hold, hold the current at said % of the stepper motors max current.

Next is Switchts 3-4 for the Buffer, the manual just has, Fast, 25%, 50%, Slow, so at a guess I need to set it to Fast.

Then the last two switches 5-6 are for the step modes, this I understand.
If you look at the datasheet here , pages 9 and 10 you will see that switches 1-2 are the torque current settings relative to maximum current(default 100%) and switches 3-4 are the Decay Modes (default I suspect should be fast). The max current is actually set by the big resistors on the board, but its hard to tell what colour the stripes are, should be Brown, green, silver, silver which is 0.15ohm for 3.3A.
