Hi Charles, and all, My BBB is making my printer move, and I'm almost to a place I can use it to make something. The system consists of a bunch of jumper wires from the BBB to a RAMPS board. Functional, but messy.
The next steps are: 1) Tweaking the temperature code to match the thermistor circutry on the RAMPS. I like that the thermistor table Charles made is based on the resistance at a temperature. I'll also need to add a second temperature input, but I think most of the framework is in place for that. 2) Outputs for a fan and two heaters (hot end and print bed). 3) Home/limit switches. I have a good idea what needs to be done here, except that I can't find out how to map to the pin on the BeBoPr. I mostly need help with #3. I see the [PRUCONF](Driver).stepgen.00.enable type lines, but how does that map to an actual pin on the BBB? It also looks like more pins on the BeBoPr might need to be added in the dts file. As an alternative, I might try to use the K9 configuration as a starting point, since there seems to be more pins that I can use.
