What?

Zortrax m200, m300 series reverse engineering to port Klipper.

Why?

Becuase Zortrax support is non existant and functionality is outdated and was somewhat limited even back wehn it was a new product.

Port Klipper

• Start porting it, see what issues come up

Android board

Evaluate options:

1. It runs on Allwinner A33 - Linux support is somewaht lacking
2. Is bootloader locked / eMMC encrypted?
3. Custom Android instead of linux if possible?
4. Just make a a SOM board with Raspberry Compute, Digi or Variscite SoM to fit same mount and talk to same display and touch?

• Research the CPU support
• Evaluate feasability

Extra mods / changes

• Add vibration sensor for input shaping
• Replace ribbon with wire harness and drag chain
• Bigger motors for 300 series
• Use native Ethernet, if Android board is changed to somehting else
• Add magnetic layer to heatplate to use with flexible paltes
• Add load cells to scan level precisely and without electrical contact (worst design chopice of all M series)
