https://www.bilbycnc.com.au/DispProd...=WRMR2Thermo2I have been told that it is typical, and from Bilby's site links, message #2 that I am getting still points to the thermocoupler as the failure. I can not see any problem along the wires, so I assume the problem is in the head itself. Does anyone know of any being sold in the USA, with better quality parts like posted above? Thank you for looking.
