Hello. I have an A20M printer. I have a problem with the extruders. I know that CURA is not good with the 2in1 ends, so I decided to try Simplify3D. Small models work well but on larger models at some point one of the extruders stops and the print goes on always with the same filament. It happened twice and each time with different extruders. After print finishes I have difficulties to use the extruded that stopped. Contacted Simplify3D support and it seems that cgode generated the correct commands to change extruders. Can anyone help? Thank you.

Hi, Can you provide a specific video or picture?
So that we can solve the problem better.

If you use it for monochrome printing,
you also need to insert consumables on the two hot ends to prevent nozzle clogging.

For the hot end cleaning, you can refer to this video:https://www.youtube.com/watch?v=oBRXsBmZ9_U

I will try again tomorrow and take some pictures.
Thank you.
