I just bought v2.1 of the Wanhao Duplicator i3. I plan to use it to print wax models for casting and I’m trying to use a machinable wax filament that only requires about 140 degree hotend temperature. I see now that the firmware requires a minimum of 170 degrees temp in order for the extruder motor to operate.
I tried issuing a M302 command in order to disable the cold extrusion protection but it doesn’t seem to help. I think I need to disable it in the firmware and re-flash, but I have no source for Wanhao firmware. Does anyone have any solutions? I’ve Emailed Wanhoa but haven’t heard back.
