hi please open a thread on the forum: https://forum.duet3d.com/

HI Javier. we would need more information about what both those Y motor connections were used for on the ender 6. Please discuss this on the forum (forum.duet3d.com).

when using 5V singled ended signals connect the +’ve signal on the driver to one of the two 5V pins on the EBOB and the -’ve signal on the driver to the step-, dir- or en- on the EBOB as appropriate. There is no issues connecting multiple +’ve signals on the drivers to the same 5V pin on the EBOB. See: https://forum.duet3d.com/topic/17535/sol...

The circuit can handle 2.5A, so when supplied from VIN higher currents can be switched. the 12V limitation is based on the on board power supply. Obviously the lower limit of the two applies for 12V, that applies to any pins that are set to use the on board 12V supply.

Hi Joshua, please use the forum (forum.duet3d.com) for support questions.

Yes it does.

Bed heater (up to 18A1), 2 x extruder heater (up to 6A each), also 15A for bed, 7.5A for stepper drivers and extruder heaters, 1A for fans.

Some of our resellers have them already and others will be getting stock soon.

As long as it does not interfere with the pins that the SBC <-> pi interfaces uses it should be fine.
