tool change location in cura

Recommended Posts

Posted · tool change location in cura

Hi I am using cura 3.2.1 with marlin 1.1.8. I am curious if there is a way to change the tool change location in cura. I am using a 2 to 1 hotend. I have start and stop script in cura working properly to pull the unused material out of the hotend and swap in the second material. that is all working as it should and I can get successful prints. however during the swap the nozzle stays over the last printed part while the switch happens and the nozzle temperature is adjusted for the new material. this leaves small blobs from time to time. in slic3r the hotend moves to x0 y0 during the tool change and then heads to the prime tower both wiping the possible ooze and clearing the material. I would be happy if I can get cura to do the same or at least hover at the prime tower. is there any other information I need to provide to get some insight on this problem?

I don't really have experience with this, but I'd guess that you need to make the movement to (0,0) and back part of your start and stop scripts.

 

So at the beginning of your stop script, store the current position of the nozzle and move it to 0,0

At the end of you start script, move it back to its previous position

 

Sorry I can't show you Gcode, but I'm guessing some one else can help or if all else fails, Google it.

that is helpful. I figured I could add a position to the beginning of the start code but I wasn't sure if the printer would head back to the print position on its own. I will have to give it a try.
