This I have somehow missed - currently there is no jumper on those pins! I was getting crazy trying all sorts of things to get it to work. Thank you guys!

Hey guys,

I'm running 24V on my duet 2 wifi with RR firmware 3.0beta12.

I want to connect a 12V print cooling fan to the duex5 now since it can convert the 24V to 12V for fans. I can't seem to get that to work.

I've changed the jumper of "V Fan Fumper Select" to the middle position (12V) and then connected the fan to the FAN3 pin.

After that I have added the following to my config.g

M950 F1 C"duex.fan3"
M106 P1 S0

As tool definition I put the following:

M563 P0 D0 H1 F1

I can't get the fan to work this way. I have checked the voltage at the "duex.fan3" pins and they don't seem to be getting 12V at all (multimeter says 0V).

Any advice?

Thanks!

As I have defined M584 Y2:1 shouldn't be M574 Y1 S0 P"zstop+ystop" correct?

@Veti what do you mean with swapping the endstop connector?

Thank you very much! This is what I was looking for.

This following Gcode works:

M574 Z1 S0 P"zstop+ystop"
M574 Y1 S0 P"zstop+ystop"

Is there a possible bug in the documentation?

According to the doc, this should work:

M584 X0 Y1 Z2:3 E4
M574 Z1 S1 P"io2.in+io3.in" ; Z axis with two motors, individual min endstops, active high

In my config I have the following:

M584 X0 Y2:1 Z3:4
Now when I add M574 Y1 S0 P"zstop+ystop" to this it results in the endstop connected to the Z motor to be ignored.

Only when I declare it like this:

M574 Z1 S0 P"zstop+ystop"
M574 Y1 S0 P"zstop+ystop"

it does what it is supposed to do: home the "z motor" and "y motor" until they hit their designated endstops.

Hey there,

I am currently running a custom printer which needs two y axis endstops to align and synchronize the y axis. I have recently updated my duet 2 wifi to RR firmware 3.0beta12 and since version 3 now works with multiple endstops per axis out of the box I want to use that feature. How would one set that up?

My y axis is currently mapped to motors 2 (z driver) and 1 (y driver) and my y axis endstops are connected to z and y endstop pins of the duet. Is the following sufficient to set this up so that both y axis motors move to home until they both hit the endstop?

M574 Y1 S1 P"ystop"
M574 Z1 S1 P"zstop"
M577 P"ystop+zstop"

Thanks in advance!
