QuoteDjDemonDYes it is equivalent. Thank-you!by loddie - General
QuoteDjDemonD ...use an rcd or rcbo type device on the mains supply to trip power in case a wire or the heat bed shorts to anything. I'll be using a GCFI outlet to plug the printer into. Is a GFCI outlet functionally equivalent to an RCD/RCBO?by loddie - General
Hi Simon, Thank-you for your thorough reply, especially as it has been a while since you wired your 3D printer. I will leave the jumper on "H" as you have explained it well. As yours was 240V and mine is 120V, I wanted make sure the jumper wasn't for switching those voltages. Also, thank-you for the other safety advice both here and other threads (e.g., here). I've take careful notes of yourby loddie - General
DjDemonJ, Thank-you for this thread and sharing your schematic. I'm rebuiliding my 3D printer (Raise3D N2) for a 120VAC heated bed and will include this smoke detection/safety circuit when I rewire everything. However, I have a few questions: 1. I'll be using the same 9V power relay. However, I cannot find a spec sheet for it after much searching. What is determines if the jumper should be setby loddie - General
