Great, thank you.

Yes, all as described.

The endstop switch seems not to be recognised as the state shown in the machine properties tab remains the same. Same behavior for E3_STOP.

The cable between switch and duet and the switch itself are tested and function properly.

My Duet was updated to 1.21RC1 before I wrote the above. I‘ve tried to trigger with an standard mech endstop v1.2 connected to pins 2,3 and 4 (i.e. gnd, +3.3V, E2_STOP) of the expansion connector.

Hi,

I hope you can help me with the following problem:

E0 Trigger is used for the u axis mapped to E0
[c]M584 U3
M574 U2 S0[/c]

E1 Trigger is used to trigger the emergency stop
[c]M581 E1 S0 T0 C0 [/c]

Is it further possible to use the E2 end stop to trigger "T#" without a Duex connected? I've tried:
[c]M574 E2 S0[/c]
[c]M581 E2 S0 T2 C0[/c]
and created the appropriate "trigger2.g" in the sys directory. But this does not seem to work.

Hi David, my question about the scara support seems to fit in this thread …
I'm currently using a Duet wifi to control a delta and now also a Duet ethernet to control a Scara. In the latter one I would like to implement a scond Hotend (for the configuration please see the attached sketch). Is it possible to implement the gamma angles in M669. Currently alternating between the hotends is only possible with manual editting M669 Bnnn:mmm according to the gamma angles. Or did I missed something?
