@droftarts thanks a lot. I know the Zip download. Cool would be one button. I will look in the other options.

By the way, after changing the SD card to a new one, I did not face the issue anymore.

Thanks.

@AlexZ, it is unlikely to be the mosfet. Generally when they fail they do so permanently.
Is the new heater a high wattage heater (more than 40W)? Is your heat block a copper block rather than aluminum? In both cases I have found that standard PiD tuning is less than ideal and needs hand tweaking.
Also, the actual temperature graph may tell you more about what is happening.

@bewaren the sharp dips suggest to me that you have an intermittent connection in the wiring between the thermistor and the Duet. This is most likely caused by a bad crimp connection at one end of the cable between the Duet and the Smart Effector. But I suggest you also check that the soldering of the 8-way connector on the Smart Effector looks OK, in particular that all the pins have been soldered. That connector is hand-soldered so mistakes are possible. Likewise, check the soldering of the 2-pin temperature sensor connector on the Smart Effector.

@gixxerfast said in BL Touch not working:

Which version of RRF are you using, ver 2? I can't see that you've mentioned it.

EDIT: OK, so you're using RRF 3.3

Then I think you should config the BLTouch differently:

Have you read this bit, "Software setup (RepRapFirmware 3)" for the https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe

Either I'm a sloppy reader or I can't see that you have the M950

AS in this example:
2. Create a GPIO/Servo pin index using your chosen control pin, for example:

M950 S0 C"io7.out" ; Duet 3 MB6HC
M950 S0 C"io3.out" ; Duet 3 Mini 5+
M950 S0 C"exp.heater3" ; Duet 2 WiFi/Ethernet
M950 S0 C"duex.pwm1" ; Duet 2 WiFi/Ethernet + DueX2/5
M950 S0 C"!exp.heater6" ; Duet 2 WiFi/Ethernet + BoB
M950 S0 C"zprobe.mod" ; Duet 2 Maestro

Thank you, that did the trick! I must have overseen that section and used outdated sources. There are so many out there, you don't see the wood for the trees.

Also my deployprobe.g and retractprobe.g files referenced P7 rather than P0 as was mentioned in one of the guides. But these files reference the probe input rather than the heater, so P0 is the correct setting.

These are the correct settings and corresponding files:

Thank you for your help! You made my day!

@MGJosh said in Duet2 Ethernet v1.04b - shorted D13 putting 5V OUT on USB?:

I apologize in general for the loose implication.

don't do that; people need people to question things in general to improve stuff in general!

@bearer said in Bed heating issue now that I'm on 3.1.1:

you don't even need to temporarily store it in config-override.g, you could just query the paramters an copy that into config.g from the gcode console afaik?
and thats fine when you know what you're doing,...

This is what I am doing, editing the printed parameters into the M307 in my config.g file.

Always wonder why the Duet don't just prints the recommended M307 and planed to ask Duet3d to add it so here it is https://forum.duet3d.com/topic/17958/feature-request-please-have-m303-printing-the-recomanded-m307 . Feel free to support that request 😉
