Im not telling you what to do, but these cheap plastic psu are not a good option and sadly the often come with the hardware, this is a problem consumer electronics often have.

I did also mod my axes with other fans and psu. The 5amp psus are 12 € each

The new firmware runs them 5 degree cooler (ultra and supra) … that i can not make a diagnosis from here, is almost clear.

But it would be the first thing i would try.even computers get strange errors with…all electronics and bodies basically cant work with a “heart”
