Thanks so much for these replies!

I did not know the Duet tool board existed.
Sadly I am still on the Duet 2 Wifi so the toolboard is not compatible.

But probably my reduction to common Gnd, Vin and 5V and a splitter board on the printer already is enough so I can fir everything in the 7mm cable chain.
And I also love the ide to be able to unplug stuff on the carriage board and not having to undo all cabling when changing one component.

I found the solution! The issue was with my NGINX configuration limiting upload file size. Here's what fixed it:

In my NGINX config for the domain, I added:

client_max_body_size 100M;

location / {
    # existing settings...
    proxy_read_timeout 300;
    proxy_connect_timeout 300;
    proxy_send_timeout 300;
}

This increased the max upload size to 100MB and extended the timeout to 5 minutes. After restarting NGINX, the 413 error disappeared and I can now upload larger files through my domain without issues. So happy to have this resolved!

I only hold the calliper there to visualize the problem. I made dozens of measurements in multiple prints.

@droftarts I have the 24V heater since a long time already The problem back then was i had all my wires through a cold water connection hose and could not change single parts.

And also, even though I planned to change the heater block anyway, I can not accept a problem to be just "unsolvable", especially with software. I thought there must be a way, just for my ego so to say.

Indeed it was your approach M307 H1 ... after the M950 H1 ... that solved the issue!
Big times thank you for this again. Made the printer last for some important prints before the heater core swap.

I understand the safety concerns, but for me, it makes no sense to destroy someone's reputation because he asked for advice.

Thanks for helping out on this one and for the upvotes!

I will update you when my new carriage and daughterboard are finished.
