OB 1.4 changes
thingiverse
To suit my requirements, I modified Wired1's Openbeam 1.4 printer design by incorporating a Printrbot Extruder. I also integrated components from Hossmachine's OB1.4 derivative, such as the X axis endstop/Z axis adjustment screw combination and the Z axis endstop bracket. To ensure compatibility with my Jr version, I divided Wired1's y-carriage into two parts, printing them on the Jr in PLA and then bonding them using super glue. Once I achieved a satisfactory calibration for OB1.4, I printed a fresh carriage employing my new printer. All adjustments were made to the original STL files within Tinkercad.
