Heatbed doesn't reach desired temperature

I just got my new Prusa Mini and having issues right away!

After assembly, tried calibrating and it I am stuck in this process -- loading ASA filament, the heatbed stops at 90deg and gives me an error.

Despite being brand new out of the box, checked all cables for damages all the same and none found.  I reset  the printer the fifth time to calibrate and this is getting frustrating!

RE: Heatbed doesn't reach desired temperature

Isn’t 90 degrees actually cutting temperature for MINI? I don’t recall if it’s 90 or 100. I don’t think many people calibrate with ABS plastics and there may be some oversight in calibrating gcode vs cutting temperature in firmware. Do you have some PLA at hand to try and get through calibration first?

well that may make sense.  although on my 2 other mk3s i have no issues calibrating with ABS filament but then again, the difference may be the Mini... will try it again, but I sure hope I can use it for printing ABS, the very reason why I got it in the first place.

@crawlerin

did exactly what you mentioned, calibrated with PLA, everything is ok, now when I started printing back to the same problem

Time for support I guess? It looks like it's "not patient enough to wait for bed to heat up", put in human terms.

Well, that's really time to contact support to get thermistor or bed replaced.
