Dear friends: My E3D Toolchanger is still debugging so far. Currently my machine only has two nozzles. My slicing software is PrusaSlicer 2.3.0, used with pspp, but I encountered a problem during the debugging process: Two print heads printing: When the No. 0 nozzle is activated, the working temperature of No. 0 nozzle is 200 and the idle temperature of No. 1 nozzle is 170. However, when the No. 1 nozzle is activated, the working temperature of the No. 1 nozzle is also 170. The idle temperature of the No. 0 nozzle is 170 normal. I checked the parameter settings of my PrusaSlicer, and the working temperature of the print head is 200. Please check my configuration parameters: May I ask what causes this? Looking forward to your reply.
