hi,
Sorry for the late answer i was really busy with exams this weeks and thanks a lot for your advices !
I've tried with the prime tower and it was exellent. I'm printing with a 0.4 AA i'm not sure i have a 0.25 available at my lab but will definitely ask.
I didn't know you could place the prime tower near the printed object so i will try to cut some print time maybe ?
I've noticed that i'm almost hitting the object when the nuzzle is going to the prime tower so i thought about checking the z-hope when retracted parameter or the z hope after extruder switch.
Your idea of printing the model downward could be very nice the tricks is that my part is similar to a plate so what coold be the best for printing a plate upward or downward ?
Thank you again for your concerns
Cédric,
PS: i'm gonna post photos of my project so you guys can follow my advancement
