Thx guys. I don’t see any issues yet but it’s early in the build. I am well versed in the “arduino foo” as I used the ramps set up for my printer. The RC8 bugfix does at least compile for me, next is hooking it up and testing. I guess I will use two setups and just reflash on the fly for the laser to a 3D printer for now.
I wasn’t planning on using a LCD if I can help it, I would rather figure out a way to send the data back to the Pi and view it on a monitor but not sure if the SPI or I2C or the Tx/Rx will be used yet.
The basic stuff like getting it to move and function I’m familiar with but the more advanced things is the learning curve for me.
