After the first few prints using the supplied Cura profiles, the nozzle has started to clog up either at the start of the print or part way through. The extruder keeps going bending the PTFE tube until stopped. Has anyone have any idea of what is causing this and what are the solutions. I have ordered a Dragon Hotend.
I am getting frustrated with the MIC-6 bed falling and printed off the parts for Johannes Weis's solution before I started having problems with the nozzle. I saw a YouTube video by Kersey Fabrications, which addressed this issue on a Creality Ender 5 by installing different Z axis lead screws with a finer lead(angle of the threads). Has anyone considered this solution ? As I only intend to use one hotend and there are two Z axis motors, would the installation of another stepper driver enable independent Z axis operation ie Marlin G34 operation. I realise this would involve amending Marlin, which is beyond my knowledge at the moment but may be a long term upgrade. It would help level the bed in one direction.
Pulley Upgrade - although I haven't had any problems yet, they don't look that secure. The Pulleys that I purchased for the Z axis synchronisation upgrade are very similar in size to the supplied bearings and washers but with a deeper flange. They have a deeper flange than the suggested flanged bearings. Has anyone used pulleys successfully ?
