The dining table chairs came with ‘fake leather’, which is actually quite common.  Fake leather comes in one of two flavours: PU leather (polyurethane leather) and vinyl bonded leather.  Vinyl bonded leather has leather fibers glued to the back of the vinyl to allow vendors to legally claim ‘10% genuine leather’.  If you inspect the […]

Solution for when 3D printer won’t print first layer properly (under extruding)

June 25, 2019

Syptoms When I change the spool of PLA or PLA+ filament on my 3D printer or use the 3D printer after not having used it for a while, I am often having problems where the printer seems to be under extruding, where there is poor bed adhesion and where tuning the printer does not seem […]

GCODE maiden flight Some important Gcode instructions: G20 = everything is in inches G21 = everything is in mm G90 = everything is in absolute coordinates (go to coordinate position) G0 X30 = move to absolute X coordinate position ’30’ on the X axis. G91 = relative coordinates (move relative from current position) G0 Z30 = […]

Some of the 3D prints take a long time to print. Good bed adhesion is important: I purchased 2x 3meter length 25.4mm OD (1 inch) 1.2mm thick galvanised steel round tube from the local hardware store and 1x 1meter length. Round tube #1 (3 meters): 1064mm + 1064mm + 864mm Round tube #2 (3 meters): […]
