X2 and Y2 stepper not moving (Rambo 1.4)

Mostly Printed CNC - MPCNC Troubleshooting
1

I just finished assembling hardware and 3d printed parts for MPCNC build.

before I place the stepper motors in trucks, I wired everything to make a test run but unfortunately not all steppers work. X, Y, and Z are working fine but X2 and Y2 are not working.

I flash the V1CNC_Rambo_Dual-2.0.7.2-src firm wear into Rambo 1.4
I still don’t connect endstops

here are some pictures

That’s not our firmware. Ours doesn’t support that screen and it is 2.0.7.2, not 1.1.9.

I download the firmware from v1 GitHub page https://github.com/Allted/Marlin/tree/V1CNC_Rambo_Dual
but I bought the Rambo 1.4 from Aliexpress.

Seems the issue is in the screen I use, is that right?

The current release point for firmware is here. Even an old version of the Rambo Dual firmware should have had X2 and Y2 moving, so I’m not sure what is going on. Update to the lastest version and see what happens. Note you may need to make firmware changes to support this screen.

Even that firmware is based on bugfix-2.0.x. You didn’t successfully flash it.

Get the latest from MarlinBuilder releases (which is the same zip that Robert pointed to, but presented a little more organized) and use Xloader to flash it.
