Smoothieware on the PRNTRboard

Thanks to the huge work by Matt Baker, I now have Smoothieware V1 booting on the Prntrboard. Matt did an excellent job with the initial port of Smoothie to the STM32 series of CPUs. I did some tweaks and added a target for the NUCLEO-64 board I’m using. After a few weeks of work it does boot and I can verify the temperature controller works.

It does not have all features of the original Smoothie board (no SD-card and no Network) but I do have better drivers – TMC2130.

Here is a picture of me testing the hot end heater control:

The heater was set to a “safe” 55 degree Celsius. I would say the PWM control for the heater is much “smoother” on the Smoothieware.

My port of Smoothieware V1 is on github. My working branch is stm32f4. I also have stm32f4-tmc2130 with the TMC patches.
