I made sure it was the correct firmware but l'm not sure whether the 2.5 to the mk2.5mm would affect it. l might try just installing the 2.5 firmare alone without the new 2.0 mm and see if that works.lee.o wrote: Dumb question, you did install the MK2.5 firmware, and made sure to install the correct version for your RAMBo board?
The changes are more than just skin deep, the printer won’t just know it’s a 2.5 without the new firmware.
Prusa have told me it might be a faulty signal wire may be worth asking if they think you’ve got the same problem. I’ll tell you if this solves my problem when it arrives.john.s91 wrote: Same problem ?? I get a fan error on my newly received Mk2.5S kit which was originally working fine. I was about to calibrate the nozzle height when I came to preheat the for PLA I got an error about a fan. So I re-ran the selftest.
The error say please check left hand hotend fan wiring error BUT this fan is powering up OK ???. It clearly stops the test before it tests the front cooling fan ??
