As always thank you for your prompt reply!

Hello,

I'm aiming to setup multiple hot ends for my printers. This means that every hot end has its individual:
heating cartridge,
thermistor ,
heat blocks and
nozzle diameters etc.
Due to the different physical setup each of those require a individual PID tuning for a certain temperature.
Rather than doing a PID tuning each time I'm exchanging the hot ends I'd like to setup a PID setup Macro for each individual hot end.
From my understanding it is recommended to use use M307 command based on the computed PID values after tuning? In other words I can copy M307 command for my Macro from config_overwrite after saving values with M500.
I have several printers with the same hardware setup but differences in build volumes used Duet Boards (Not Firmware) and of cause e.g. internal power cable lengths or in general wire lengths . Between those I can technically change my hot ends without any issue.
Can I use a created PID macro I have generated after tuning one particular hot end on one printer and transfer it to another printer of the same type, or would you recommend to have a individual tuning of each hot end on each printer due to the physical differences between printer hardware?

For Which purpose would you generally recommend to use M301 command?

Thank you
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.

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

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

Hi,

I'm using a Duet 2 Maestro with firmware 3.01-RC4 running.
Is there any slick possibility to implement a door switch which sends the print straight into pause mode/position?
I was initially thinking about to use a filament monitor using M591 command. But I failed.
I implemented the the code into config.g "general prefrences" as follows
M591 D3 P1 ; Door Switch (D3 = Driver 3 for E0 Motor/ P=High signal when door closed)

I'd be happy to receive a comment on other solutions.
The potential alternative solution using M581 and M582 on a maestro did not become cleare to me until yet.

Thank you and Happy Easter
Dominik

@droftarts said in Remove heatbed completely:

M140 H-1 ; Disable heated bed

Thank you, this worked. DWC now does not show the heatbed anymore. But PanelDue still shows a heatbed. Is there a way to eliminate this?
