Hello, thank you very much for your help. Soldering the 1K resistor directly in front of the sensor board helped. I have a stable signal. Tested several times, flawless. I also think that the connected shielding also helps.

Thank you again.

Hello, I have now found out that I have to adjust my Config.g etc. etc. significantly. Because without adjustments when updating from 3.4.0 to 3.5.4 the print head moves in the bed and the heights probably don't match the firmware.

Because I don't know what I have to adjust (I tried), the topic can be closed and I will stay on 3.4.0 and live with the not so optimal or non-functioning mesh bed compensation during printing.

Many thanks to everyone who wanted to help me

@dc42 Hello,

the plugin has started.

@Phaedrux
Under 3.4.0 it is not possible to compensate for these height differences with the mesh bed compensation or it is useless. Open perimeters and sometimes too deep areas without compensation. So I hope that the update will bring a significant improvement. I print on 15mm GAL cast pure aluminum, so I cannot manually correct anything on the print bed.

I'm not at the printer today. I'll try it tomorrow. Shouldn't the G29 S4 command output something and what does the new plugin look like? I only know the old height map from 3.4.0 (top left in the navigation). Or does the new plugin and the G29 S4 command only work when a new map has been created?
.
I did the update in the hope that the bed compensation for large beds (1m diameter) works better than in version 3.4.0

Today I did a FW and DWC update on my Duet2 from 3.4.0 to 3.5.4. The height map module is now set up as an extra plugin. The updates have been installed properly, but my saved map is not displayed, the G29 S4 command also ends in a "not supported" command and I can't see any visual changes. What's wrong here? Can someone help me? I only did the updates, no changes to the config or anything like that. I tested different browsers and deleted caches.

Blinking means that I don't get a constant current at the connections for the print head. neither on e01 nor on e02. if i want to heat, the SSR and the LED on the board and also, interestingly enough, the LED lighting flash at regular intervals. icu can rule out the wiring, which sicu hasn't changed in the last year. my system is on 24 volts, the bed heater on 230 volts. I have already replaced the SSR. my next guess is the board, looking for ideas if it can actually be the board before I swap that out.

I've had to overcome a few problems over the years, but here I need some swarm knowledge.

I have the problem that the print head on my Duet2 no longer heats up, but only flashes, flickers or whatever you want to call it. That means I only get a jumping signal on both ports and no longer have a constant voltage. Ergo, the head does not heat either. This goes so far that the LEDs in the printer also flash, as well as the SSR.

My first thought was a defective SSR, so I replaced it, but unfortunately that wasn't the solution either. The second approach was to change the port, but that's not it either. Fuses are all good.

Can anyone give me sound advice on where to start?

A Magnum+ with 2x 50W heater is installed. Has been running flawlessly for 1 year now.

I look forward to hearing from you

Hi, you can change the machine Name in config.g with the M550 P“machinename“

This Name ist shown in the Top of the DWC.
