2 Problems. Hotend fan running at full load, and crashes when start printing.
Hello sorry about my bad english( google helps me). I have 2 Problems with my upgaded MK3s to MK4. I would like to know whether your hotend fan runs at full load all the time. For me it runs at around 7300 rpm from the start of printing.
2nd problem.
Now and then the printer crashes when starting a print both via Prusa link and directly from the USB stick, with the red screen diagnosing an overcurrent on the heatbed. But if I start printing by first activating preheating and then starting the file without waiting, it works without any problems. But it doesn't do that with all GCodes either, because it crashes. Firmware is the current official one. P Slicer is also current. Hope you can help me.
