Protomaker 3D Printer Threaded Rod less wobble Do NOT do this br br Not fully tested but seems better, more to be done later. IMPORTANT Opps!!! br br I wasn't thinking straight, taken out the anti-backlash system to reduce wobble seems to help reduce the wobble BUT the anti-backlash is needed when first homing. br br During homing the z axis moves down trips the z end-stop goes back up a short distance and comes back down, a bit slower, to doubled check the zero position, this means the Z axis does needed to go backwards and forwards and that the anti-backlash system is required to reduce errors here. br br The whole build could be impacted by removing the anti-backlash system so I do not recommend doing this. br br These are just ideas I have not recommendations, so don't copy unless you think they will work for you and triple test everything. br br Was advertised for spares or repairs. br br It may take some time to get this 3D printer working to a level where it is usable due to lack of budget br br Powder Coated Mild Steel Structure With Acrylic Build Platform br • Product Type : All In One Printers br • Cartridge Type : Original br • Utility : 3d Printing br • Printing Output : Colored br • Print Technology : Fused deposition modelling (FDM) br • Size : Large br • Other Features : Powder Coated Mild Steel Structure With Acrylic Build Platform br • SUPC: SDL051787633 br br My Wordpress Blog will tell you more about:- br br Protomaker Black Sprint Original 3D Printer br br br br Tweets about 3D Printers: tips, hardware software, filament ,etc... br br br br .
