@travasky said in Chamber circulation fan control:
@mrehorstdmd how are you getting around the fans turning off / pulsing when the chamber hits the target temp? In the original machine fans were on 100% of the time the machine was on. In my case I'd like the ability to control them if I decide to print a material other than ABS for example. I added a heated bed to give me flexibility on materials instead of the plastic build plate that was passively heated on the original. Seems like a shame to not be able to use or not use the fans at will.
I don't. The fan turns on and off with the heater. The printer is tall and the heater/fan located at the bottom of the machine. I only heat to 50C when printing ABS and don't want a lot of air movement at the print, so for my printer, it's fine that the fan is low powered and doesn't spin continuously.
