Should I go back to 3.4.6 and wait? (The Maestro ran fine with that version.) I started with 3.5.0 on the Mini 5 and initially thought the board might have a hardware issue.
But now the printer is running smoothly with the 3.6.0-debug firmware.

After switching from the Maestro to the Mini 5 WiFi, my printer occasionally stopped or crashed without any apparent reason. I found this thread and installed the 3.6.0-debug firmware from dc42. Since then, I’ve completed over ten prints, including some taller than 150mm and others over 4 hours long, with no crashes. My printer is a CoreXY setup with dual Z-axis and a single extruder.

@DronBroks said in Duet Web control is not available at time of printing:

After the transfer of the Ethernet cable from the printer body, hovering stopped interface (tested on a daily print interface can be accessed at any time)

Any new infos here? I have also a problem with network connection. Sometimes I lost connection (mostly after upload a file - bigger then 10 mb)
