Hi! Around the corner, aka the 3d printing world of the RepRap universe, the jump from arduino to ARM microcontrollers is on the road. This means, that descend trajecory planning is now theoretically possible. Is there any place, where one could learn how the motion planning _really_ works,

I'd prefer not to use the mesa encoder primarily because I want to use the optical isolation I already have on the 7i37. Additionally with the firmware setup I have (4 pwm, 4 encoders, 4 stepgens) and the 3rd 50 pin cable for io like estop and limit I only have one Mesa-based encoder available

I'm not sure what your budget it, but the Mesa 7i65 card has a number of analog inputs. It isn't cheap (compared to other Mesa cards) but rarely have I found good analog inputs that are cheap in any I/O system. Plus cheap is relative when you consider other I/O systems. I'm currently
