I have success. I could now supply an after market Controller for the CubeX.
Using there software in a re engineered controller using the same PIC processor. The PIC32mx440 and running the standard BFB file KISSlicer was written for I could make a after Market controller with there software that would be a straight swap over.
You would plug in and work just as it did before same display use files BFB extensions with no need for after market filaments and all other locks gone.
It will be cheap and under warranty it would also not fail by using different peripherals circuits. The key is another micro controller piggy backing the other system processing other electrical signals and replacing them making it compatible.
I have added a separate Lcd display and key pad to this little chip
so the user can if they want to make alteration on the fly.
I will continue for now refining the software and testing the system.
On my prototype is all birds nest wired and Vero board.
I already have some very nice prints.
