Hi everyone,
I’m working with some difficult to handle materials and have noticed a curious behavior while attempting to dial in the material parameters. I would love to know if this is somehow related to my setup, or if this behavior can be observed by others as well:
The initial extruder of the first layer in my case is the right extruder. When the printer switches to the left extruder on layer 2, the order of operations is
- switch nozzle
- heat the new nozzle to target temperature
On all subsequent toolhead changes after the first one, the order of operations is reversed:
- heat the new nozzle to target temperature
- switch nozzle
This is causing me problems because I am working with very sticky material that sticks to the ooze shield if the nozzle is heated to full printing temperature prior to the swap and causes massive contamination afterwards. I have also inspected the g-code of the filament swap of the various layers very carefully and it is literally identical. As I am beginning to doubt my own sanity, I would love to hear from others if they can observe the same curious behavior on their machines.
Thanks everyone for your help. I greatly appreciate it.
