CTC Upgrade 02

My CTC Bizer was having problems with static build-up disrupting the SD card and causing the print to fail (read more here).

I also explored other possible problems and decided to solve a lot of them all at once.

Things I needed:

• Static shielding for PCBs
• Static shielding for ribbon cables
• Grounding for PCBs
• Move stepper motor wires away from PCBs
• Add better surge protection/UPS
• Check for wire fatigue
• check all wire connections
• Test SD card
• Test if there are software/gcode problems

The main thing that solved my problems was static shielding/grounding for the SD card and LCD PCBs. I used aluminum tape and kapton tape for shielding. Also, moving the stepper wires away was important (they produce a lot of electromagnetic interference).
