The DualLR firmware is for the LowRider, and only has 1 X axis driver. The 5 drivers for the Rambo are therefore X, Y1, Z1, Y2, and Z2.

You want the V1CNC_Rambo_Dual vewrsion, which will be set up for wiring as per your link.

Ack. I looked at the section (MPCNC) and not the thread title. (Duh.) EDIT: Fixed the section…

So if you’re building a LowRider 3, then you have the correct firmware, but there is no X2 driver. Instead the drivers are as I labelled above.


Here’s your wiring diagram, I just relabelled the motor and endstops. (I might have mixed the Z endstops)

Thanks I will try that tomorrow so I assume I will need to use a Y connector for the X axis. Not sure how it will be able auto squar its self without independent motor control. But definatley not working the way its hooked up now :frowning:

Looks like I have my XY understanding mixed up. For some reason I was thinking X was the long side of table now its making sence

THANK YOU !!!

Uh… No, there is only one X axis motor. I think you may be confusing the way that the machine is set up.

X axis is along the gantry of the LowRider machine.

Y axis is along the table, and has 2 motors, one on each side.

Z is of course vertical, and has one motor on each side to lift the gantry…
