Welcome, I have Vertex printer and I have trouble. A big object is printed quite good, but if i print a small object, I will always have a problem. The problem is something like an extruder(I mean motor which moving the filament) don’t provide suitable amount of filament and then I have barren movement of extruder (I mean a Extruder is moving but filament doesn’t flow out and as you probabliy know I have to kill a process). What should I do? Who is guilty? Extruder? or motor? g code?
If the extruder is trying to extrude but you hear it clicking and turning back a bit; it means it can’t push the filament fast enough trough the nozzle. You probably need to print at a lower speed, or you have filament jam in which you should lower the nozzle temp and/or lower print speed.
Try changing the the retraction.
3 or 4mm
Retraction speed 110 - 150mm
PLA temp 190C
