there is no 3d printed spring in v1 or v2, that was part of the prototypes only.

it is important to note these instructions are for stand alone Duets. Those using a SBC running DCS should follow the instructions in getting started with Duet 3. This is the first bullet point on this page:

* These instructions are for updating firmware on Duet 3 (all boards, in standalone mode), Duet 2 WiFi, Ethernet and Maestro boards only. Updating firmware for Duet 3 using a Single Board Computer (eg Raspberry Pi) is quite different. For Duet 3 + SBC firmware update information, see Getting Started with Duet 3.

Getting Started With Duet 3

In conditional gcode and indeed all arrays in RRF are 0-based

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