Okay to summarise I bought two extension boards one from eBay Tiertime the spare one from UK shop and the other one Cetus sent from China and I paid big bucks to DHL it to me. The first one does not allow the motherboard to boot up and connect to Up studio. Second one has the thermistor problem and I have put in a new ticket to their support channel let’s see how they respond. All started when my heated bed flat ribbon cable sorted out and took the extension board out.I promise you I’ve been really careful in installing the printer parts and this is all kicked off because the heated bed ribbon sorted and took out the extension board. Jason can you help me on this perhaps?
