Hey, when i want to print something which has 2 colors in it, therefore switching the extruder every layer and so on, I have seen a problem with the switching part because every time it switches it just stops a bit before moving on and when it stops it kinda drools out filament and slacking it onto the print. It is not much every layer but it stacks up and after a while there is a whole lot of material that should not be there and makes problems to the hotend becouse it can get stuck there aswell. Anyone has the same issue or has anyone had succesful prints with teh double extruder? The calibrate part went pretty fine but there arent many layers.

at my printer the fans which are turned on with the software (one the touch screen) are not working, seems like they dont get a signal at all, does this occur to someone else aswell or is ity only me?
