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?August 27, 2019 at 5:46 pm #111094
What is it you hope to get from grbl that Marlin doesn’t do? Not challenging your choice, just wondering.August 27, 2019 at 6:16 pm #111098
Mostly I just want to learn it. But I’m also hoping to get better results with the laser.

Grbl’s laser mode is quite useful, sort of like a linear advance but for laser power.
Try bcnc, I use it on the pi, great visualizer and even some cam generator plugins. Easy to switch laser mode on and off as well.August 28, 2019 at 9:03 am #111164
Looking briefly at bcnc, it appears to have a Linux GUI that can be used with a monitor and keyboard/mouse attached to the Pi rather than just a web GUI that needs another computer to access. Is that correct? If so, that may be exactly what I want.August 29, 2019 at 3:45 am #111246
Correct. There’s also UGS which has a lighter resource requirement.
Here’s the image I used to use before, comes preloaded with bcnc/chilipeppr/ugs/cncjs, as well as firmware updater, grbl firmware updater, ssh enabled, and vnc servers already setup.
