Could you provide your config file? Also the frimware version your running would help.

upgraded Firmware to 2.02.

same issue

dc42

Are you saying that as soon as you apply VIN power, all three heater LEDs on the Duet turn on? If so, please power up the Duet with the SD card removed, to eliminate configuration issues. If the same thing still happens then the mosfet driver chip is faulty or not properly connected, and you should ask your supplier to replace your Duet.

Nemesis

@martin-s To me the config seems fine.

One note though, I'd advice you to remove any password before posting

Martin S

@dc42 thanks for your reply. I know you must be busy.
Yes. all heater LEDs turned on and all heaters get current and warm up. I finaly switched a jumper to ext 5v EN and it seems to work as it should. I thought that should have nothing to do with my issue but it solved my problem. I'll give your "power up without sd insertet" a try. But for the moment it is running.

@Nemesis thanks for your advise. as i copied the config in this post i've seen it. Its changed already.

Are you able to measure the voltage on the 5V rail when the jumper is set to 5V_INT? Be very careful not to short it to anything else when you measure it. The safest place to measure it is on the PanelDue connector.

Martin S

@dc42 i got a multimeter but got no idea where to put black and red pin. you say i can do that at the panel due connector. on which pins on the connector do I have to connect the multimeter?

br Martin

Martin S

is it possible that my problems ocure due to the fact that i just use a 12v power supply? if so... i can swap extruder heater to a 24v one and change PSU. Unfortunately I have no 24v heatbed at home to test.

If you look on the underside of the Duet, the 5V and GND pins of the PanelDue connector are marked.

The Duet will work with 12V VIN, so I don't think that's the problem.

Short update to the Status:

3D Ware Switzerland replaced the board and I finally have no longer an issue with a permanent heating Extruder and Heatbead. Thanks to Adi Hildebrand for his support. --> that means that my first Duet 2 Board has a defect. thanks for the advise @dc42
unfortunately I get stucked with homing the Printer right now. M119 seems to give me the correct Status of all endstops. But x-axis does not stop moving. it crashes the endstop and want to go further.

--> could my chinese MKS bl touch (seems to be a 3d touch which runs with 5v) clone eventually hold back my other endstops to run as expected?

Martin S

I think we can close that thread. Board was defect.
I open a new Topic for my Endstop Issue.
