Modifications
- Added Bed levelers.
- Added a Fan to cool the ramps board.
- Replaced the Multi/Poly fuse of the ramps board with a 16V/14A version.
- Added an Raspberry Pi for PC independent / network control. (OctoPrint/OctoPi).
- Added a webcam and mount to monitor the print remotely and make time-laps video’s.
- Added Z axis smooth rod stabilizers.
- Adding easy filament loading knobs.
- Added some feet to the printer.
- Adding LED’s to the extruder.
- Use hairspray on the bed (Lóreal Elnett Satin) for better adhesion.
Problems found
- The glass bed was broken on arrival (fixed by a replacement part)
- One of the flexible z- couplings is bend, resulting in severe z-rods wobble and making grinding noises (some Teflon spray helped for the noise), although the wobbeling does’t look very appealing i don’t notice any effect of this it in the resulting print.
- Once the build table couldn’t reach the home switch
- Bed temperature issues, the bed cannot hold 90 degrees when the cooling fan is switched on.
- Jumps in Y direction, the pulley came loose form the stepper motor.
- I had to tighten the X-belt
- Nozzle clogging
- added extra pressure on the filament springs.
- Settings, Settings, Settings…….
