Cannot reach 110 Celsius with a Prusa PCB Heated Bed Mk 1

No Comments

I was not able to reach 110 Celsius with a Prusa PCB Header Bed MK1. My initial installation was with the PCB traces down with a borosilicate glass on top of it. I found out that installing it with the traces up as show below resolved the issue. Nevertheless, the thermistor does not read the real printing area temperature since it is underneath the PCB. There is a 15 Celsius offset and the glass is slightly offsetted.  These are small inconveniences.  The bed is getting hot pretty fast and is able to reach 110 Celsius.
