The config is handcrafted and I'm sure I used one of my other printers as a template. Maybe my Ratrif Vcast which is already at 3.3. Keeping 5 printers always at the very latest version is a challenge.
Be careful regarding the current. The LDO 14HS20-1504S are Nema 14 witch 1.5A max: https://www.omc-stepperonline.com/download/14HS20-1504S.pdf
Yes, the overheating message showed up in the DWC. My first reflex what a hardware issue in the direction of the crimping. The fact that the error message followed the driver No. after I changed the stepper to a other driver pointed me into this direction. That so I replaced all of them and had a close look than.
Anyway, the print went trough, finally. Without any layer change at a very slow speed. I will upgrade the firmware and redo some test. I will crank up the speed than. I'm happy enough that I have at least one working setup for now. Better slow printing than none printing at all.
