X Y calculations

A project log for Simple & Cheaper CNC Shaper

I love the Shaper Origin, it could solve many needs for the home maker and care taker. But at the price many can't afford it.

It looks like the XY calculations are quite easy. Its called forward kinematics and can be seen calculated here Next I have to do interrupts on the encoder rotation to make sure I get every tick. For version 0 I think I'm going to put the encoders on the work surface and weights on the belt like a draw bot for simplicity. Then all I need is power to the drill and z stepper. For v0 the electronics will be kept off the shaper and won't have auto correct .
