I'm currently designing a RepRap 3D printer that will not have a heated bed. I have heard that it is possible to use a power brick with commercial printers lacking heatbeds. Is this possible with a RepRap printer using a RAMPS board?
I'm referring specifically to the TronXY X1 power brick. I was wondering if it we're possible to use the same TronXY X1 power brick with a standard RAMPS 1.4 board - rather than the special board the TronXY X1 uses.
As long as you provide enough energy to heat the nozzle and keep its temperature, that is possible, as steppers power usually is limited by driver to reduce noise.
