I’m a big fan of octoprint for my 3dp. I’m hoping to use it with my MPCNC too. Drew is right that it stores the gcode files on the raspberry pi. It also has the option of sending the gcode to the SD card via USB, and then prints from the SD card in the printer. I don’t know how any of that will work with the MPCNC, but it’s all just marlin, right?
Very cool setup Dave. The pronterface seems like a very good solution, too. I’m not sure how happy octoprint will be when it doesn’t have a printer attached to it, but we will see. This is a good fallback. Seems quite snappy, too.
