So I’m looking to make the switch from Marlin to grbl and I have some questions.
Am I understanding correctly that it needs an external gcode sender on a Pi, Laptop, or other computing device? It can’t just execute gcode on an SD card in the LCD screen attached to the Arduino/Ramps, correct?
Using a Pi running cnc.js gives control via a web interface. But then you still need a 3rd device to access that web interface. Is there any other alternative? I don’t have a computer to dedicate to my shop and don’t really want to do that. I’d rather something analogous to the LCD screen/SD card if running Marlin. Is there an easy option for a touch screen or a non-touch LCD screen to use with a mouse and keyboard or other type of control?
