With my Ultimaker this is a Piece of cake. During print you can select on the Printer itself (prints only via WiFi or USB-Flash disk) “Change Filament” then the print pauses, the nozzle goes into park Position so you can Change the Filament and then you can hit "resume"and the Printer heats up again and resumes printing.
I tried this with Sipmpify3D but this isn’t working automatically. I’ll try moving Z+10 X-30 (10 mm up and in x direction beside the object) and then going back before resuming. The nozzle is to hot and produces blops if not moved aside.
This should work…
I already realized a g code that moves out of the way pauses at a specific Point and goes back. But I don’t want to do this for all parts.
