Upgrade Plans
- Todo
- Install RAMPS control board, Or possible a SKR1.3 32 bit board
- Install new belts and tighten properly
- Consider installing second Z lead screw and motor
- Consider upgrading heated bed
- Complete
- New Easy Peelsy magnetic bed surface has been installed. Please do not use scrapers on it. Clean with Isopropanol before using.
- Install new E3D hotend and direct drive Titan extruder for 1.75mm filament
- Look at Z nut, currently has a lot of backlash. Complete, but Z flexible coupler needs replacing, new one is on order - Installed.
- Install new power supply - This is the next upgrade required, current power supply cannot keep the bed up to temperature - ordered.
