Hi
I’ve already had my experiences with marlin.
Got me locked down with a lot of help from this forum
built a Scara Zen table with Mega, Ramps and Marlin with an Rasspery Pi as interface.

But now I will look at Grbl and LightBurn.
Estelcam doesn’t seem to work with the Rambo 1.4 anymore.
Maybe later I would like to use the MPCNC as a milling machine.
