Exactly @jdkuki um2+ can be fully gcode controlled. Also is a pretty good machine. Since I got my hands on um3 I wanted the same, a gcode console to be able to test experiments and mods.

I suppose is just a matter of time that they add some Cura plugging or interface to be able to connect directly without having to go through Griffin. But ofc atm like @daid explained on other post, there's no 'home g28' gcode, so it might not be doable atm.

 

I guess another workaround could be using ser2net on the A20 since it looks like they give a shell with hopefully root acess as outlined in the developer mode post. Hopefully there will be some way to accommodate the new homing in the UM3

Ahh that's a little disappointing. I am looking for a printer to use in some software development revolving around a custom CAD/Slicer suite that would explicitly require that usb connection. Don't want to rip apart a 3.5k machine to do so though. The UM2+ looks like it should satisfy that requirement though, am I wrong? I understand it isn't officially supported but nonetheless possible by setting the flavor on the machine to reprap?

I noticed that it looks like the USB connection is removed from the back panel. Does the UM Board still run Ulti-Marlin? Does the A20 process some of the GCode and send the command over via a standard serial connection?
