Makertech 3D Forum

Hi, I recently saw a post from makertech 3d that they are working on an upgrade package and I was wondering what's everybody's opinion about it: My thoughts so far: It sounds very expensive and I don't want to throw a lot of money on this printer anymore. Certainly because I don't see it as an upgrade but as a fix for what should have worked in the first place. Add-in the huge custom fees (thank you Brexit) and delays and you're probably better of saving for a different printer.

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 ?

Why.. why.. was the servo arm made in plastic? This, for me, is the most questionable design choice of the whole printer. My first arm almost immediately started spinning in place.. that metal serrated washer doesn't come close to engaging the plastic. So I made my own server arm with some teeth to engage with the server gear itself, but still, that was short lived. My DSH switches without any resistance by hand.. but after a print or less of switching the server just spins within the arm. This needs to be something other than plastic.. or it needs to be well fitted to the servo.. anybody run into this issue and have any better solutions? I might just super glue the damn thing.
