how to tell what kind of motherboard is on my ctc

I believe the motherboard for the CTC printer is a ataMega2560. If you unscrew the bottom panel (it’s held on by a single screw on the bottom right side of the machine and slide the panel to the left) you can see the main board. Somewhere on there there will be a model number or name of the board.

Thanks trying to see if I can put on a blt bed level have you done that let me know

I wish you luck. In my experience CTC’s are super difficult to modify and get working right. It would be cool to see it done. Let me know how it goes.
