Are you guys looking at using the code from open servo? Or the really nice looking but seemingly abandoned code from supermodified servos? Also the alexmos gimbal bldc controllers have a lot of promise in the robotics area and reprap. Magnetic encoders?

We are using standard servo motors(continuous turn) to reduce the cost and minimize the custom or non standard vitamins. We are using a single processor to do all 12 PID loops in hard real-time. For the encoding we are using the AS5055-EQFT 12 bit SPI encoder. We are focused on reduced cost and standardized components for the first run, although expanding into more advanced applications later would be cool.

Love everything about that, considered a similar thing, with BLDCs too, partially implemented at this point. Have you looked at the alexmos gimbal code/board?

Using feedback and PID is going to make a huge difference to 3D printing and RepRap in general. It’s the only way forward to get more reliability and lower cost. If you get this done, this is a really big deal.

If you ever need any hotends or help get in touch with me at E3D-online and I will help you out.

(Shameless plug) We actually developed this control architecture for an educational development product and have been selling that for 2 years. It is called the Neuron Robotics DyIO http://neuronrobotics.com/neuronrobotics/store/dyio/ . It can now be thought as the development platform for the Bowler Communication System, the name of the communication protocol and SDK. During the development stages, extra hot ends would be Very useful, how about a trade for a DyIO?
