I own a Balco rebranding of the Duplicator i3+ and after having replaced the plastic driving gearbox with a metallic one, it appears that for some reason the extrusion temperature became unstable and I suppose I should to re-calibrate the parameters of the PID.
However, I have been using this machine stand alone and I do not have a computer nearby nor the space to put one. And since it has a tactile screen, it won't show me the result of the gcode execution.
Does anyone know of a manual procedure to calibrate a PID in order to at least stop the temperature swings ?
