sry for the repost i accidently postet this in the wrong kategory.
Hay there,
I am currently working on a small extruder project, this extruder functions in a similar way to the Dondolo extruder, but in a smaller package.
It uses a servo to switch back and forth between two Idler gears in order to print two different filaments with just one motor.
My problem is as follows:
I have to change the positive direction of rotation of the stepper to change the filament. With filament A, extrusion and retraction are reversed compared to filament B, so theoretically I have to invert the DIR PIN in the middle of the print.
Does anyone here know a solution, procedure or alternative to achieve the goal?
I look forward to ideas, answers and suggestions.
