Hi All,
Can anyone help me with my zits!?!
I'm setting up a new machine.
I'm using Cura 3 software on Linux, my printer has a Bowden setup with a tube about 500mm long. I have stopped stringing by using the retract function (4mm) but when it primes it over extrudes and produces a blob where it starts. I've tried many different settings including negative numbers in the "Retraction Extra Prime Amount" (which does not seem to do anything) I've tried many different values for the retraction, 0mm seems to create a very small under-extrusion, 1mm seems to make a very small blob in some places but under-extrudes in others but still has bad stringing, I settled on 4mm retraction but blobs are a real problem.
I'm quite sure the Marlin firmware is setup carefully but perhaps I'm missing some mechanical issue??
