The Cetus Touchscreen kit contains following items:
1. 4.3" touchscreen with a ribbon cable attached
2. CPU with latest firmware (3.76)
Since the Cetus CPUs on the market are with older firmwares that cannot communicate with touchscreen, so a new CPU is provided.
Note - following will happen after upgrade, due to change of new CPU.
1. Nozzle height value will be deleted, cannot print (model out of range), need setup nozzle value again. (it is useful to take note of the nozzle height value before upgrade and input it manually after upgrade).
2. Wifi credentials lost, need to setup WiFi connection again.
3. The new CPU's machine model by default is “standard”, so if you are using extended version, the correct ROM need to be flashed, please refer to this article: Cetus ROM Update
