Hi Timothyze,

thank you for your prompt reply and please excuse my slow feedback.

For those who are interested:

I could solve my Door Switch issue using the suggested M581 command and the extruder Extruder Endstop of E0 ("e0stop"). I have used it in a manner of triggering a "software" based emergency stop (https://duet3d.dozuki.com/Wiki/Connecting_an_Emergency_Stop)
M25 was not necessarry as M581 command now allows to directly trigger the pause print g-code by setting the T parameter to 1 (guess this only works since RepRapFirmware 3.01RC2 and later).
I'm using a optical endstop which hase a high edge when the door is closed.

Here is the code which I used and embedded into config.g => General preferences:
M950 J1 C"e0stop" ; Jnn = Input pin number (RRF 3.01RC2 and later only)/ C"name" Pin name(s) and optional inversion status.
M581 P1 T1 S0 C1 ; P1 = specifies input trigger (corresponds to M950 J1)/T1 = pause print/S0 = falling edge signal when door is opened/C1 only trigger when printing

Best regards
Dominik

Thank you!!!
This solved my issue.

Thank you for your answer.

I have modified my code as suggested with no positive result. .
It now looks like this:
M950 J2 C"e2stop"
M581 P2 S0 T1 R1

I have cross checked it with my previouse setting for a Photocell using the C parameter and it works when I use the above shown code for e0stop.

Any other ideas?

Hello I have dedicated myself once again to the topic of door switches now using a simple reed switch. Among other posts, I took a closer look at this post again:
https://duet3d.dozuki.com/Wiki/Using_M581_-_External_Triggers_and_Building_a_Control_Panel

Anyway, I have not really gleaned success.
First, here are the actual global specifications :
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2)

In an old door switch setup, with a Duet Maestro, I used a light barrier to switch like this:
M950 J1 C "e0stop"
M581 P1 S0 T1 C1

Now I want to use a reed switch with a 3,3V falling edge over I/O pin 4 "E2_STOP" and connect it to pin 30 against GND. The circuit is tested and does what it should.
Analog to the code shown above I have modified the code as follows without success:
M950 J2 C "e0stop"
M581 P2 S0 T1 C1

Even I have taken a look at Pin Name formate I have also tested different writings without success.

Anyones comment is appreciated.

Thank you for your fast answers again!

Sorry, this should have been defined earlier.
At the moment I have Duet 2 WiFi, Duet 2 Ethernet and Duet 2 Maestro in stock. Thus I can choose. Would be interesting to have an answer for each of these boards to understand my operating range.
Thank you

Hi,
I'm planning the setup of a hotend capable to deliver temperatures up to 500°C.
Therefore I'm wondering what the maximum accepted current (amps) of the heater cartridges is when using a 24V power supply.

Thank you

Thank you very much for your helpfull answers!!!

Thus the only remaining question for me is if I can disable the extrusion interface of the panel due somehow or if it is possible to tweak the extrusion speed in this interface?

Thank you very much for the fast response!!!
This will be tested in the upcoming days.

Will the maximum extrusion speed defined in M203 of the config.g file have an influance on the maximum extrusion speed in the extrusion interface of the PanelDue)

Hi,
I have built a printer which uses syringes for printing liquids.
The syrings in use have a diameter of 30mm and therefore the retraction and extrusion speed and amount needs to be controlled very carefully. This works perfect in conjounction with e.g. a slicer like simpify 3.
However, problems occur when ventilating the liquid channels, which I solve using macros on the Duet Maestro board. Here it seems to be the case that by default a minimum extruder movement speed is set. If I e.g. use the g code command:
G1 E20 F0.05
to very slowly move the extruder stepper motor and vent the liquid channels the extruder stepper moves too fast. This results in very high internal system pressures which lead to leakage at the syringe piston.
Do I assume right in terms of the default mninimum speed set on the duet wifi and is there any way to tweak it?

In addition I'd like to either tweak available extrusion speeds of the used 7" PanelDue extrusion interface or completely disable the extrusion button function of the panel. Is there a way to do one of these options?

Thank you in advance
Dominik

No Problem, it was me who did not take time to test everything in a straigh process.
