I recently started printing a lot with ABS. My bed temp is 110C and I have burnt 3 connectors. I am using 14 gauge wire. I have tried tightening all connections prior to starting the print and the prints usually runs about 10hrs. My unit sits in a closed container which runs about 103deg during printing.
How or can I hook up and external Mosfet to this board. I am currently using P2.5 for the Heated Bed and P2.7 for the Hot head.
Should I hook the heated bed to P1.23 with a separate power supply.
My Hot head shows no signs of ware and it is set at 215C
