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

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.

Thank you!

Hi,
I have now tested the board back an fourth starting from standard physical issues like a e.g. loosened contact in the patch cable.
All patch cables used were now previousely tested via a patch cable wire tester.
No defects clould be identified and all cables used are ok.
Going more into depth I identified a thermal problem. After a certain amount of time the networkloss starts. The board is cooled as suggested. When I then take a large fan, used for room ventilation, to cool the Maestro addditionally the network connection loss frequency is reduced again but persists.
All this happens without operating the printer. The printer is just switched on and the board is powered.
My assumptionn is that the board has a defect which is caused by any thermal happening on the board causing a loosened contact. Thus, my asumptionn is that the board is broken.
What do you think?
Thank you
Dominik

Hi,

After the Update to 3.01-RC7 and DWC 2.1.2 situation the irratic network loss turned even worser.
I have now updated to 3.01-RC10 and DWC 2.1.5.
The network loss persists but with a lower frequency.
All other PCs and 3D Printers, in average 20 IPs in use, don't show any connectivity issue.
Any suggestions what to do next?

Thanks
Dominik

Thank you for your support!
I have updated to 3.01-RC7 and DWC 2.1.2 now. Until yet everything looks fine.
Stabilitiy tests and report will follow up tomorrow.
Attached you can find the config.g file as requested. config.g

Hi,
I'm successfully running a Duet 2 Maestro with firmware 3.01-RC4.
However since a few days I'm experiancing erratic, but steady network losses.
Means every few seconds or also minutes Maestro looses the network connection and reconnects automatically.
All other PCs in the same network do not show the issue beeing connected to the same switch.
I have pinged the system and started logging on the board to get a better idea.
An extraction from the log file of a duration of 10 minutes is added. Event Log Sample.txt
While this duration of time I was loged in via Duet Web Control 2.1.0.

Any suggestions and or analysis steps I should undertake?

Thanks
Dominik
