So I purchased the mini-Rambo and read that it was not fully compatible with the mpcnc firmware after it shipped. What features am I missing out on? Should I return it for the full size rambo or another board?
It is fully compatible, it has 1 less driver than the Rambo board…That is the price difference.
I have the mini rambo in mine and it works great. I think the only “feature” to date that it won’t do is the dual endstop for squaring the machine. Would love to have this feature because its more CNC-like in my mind. But its certainly not a deal breaker. Just takes an extra min or two to set the machine up when you first fire it up. Other than that its all the same.
Old thread but from https://www.v1engineering.com/mini-rambo-1-3/
The mini-Rambo has four drivers, this means no dual endstop firmware on this board with out some skills and an external driver.I missed this also but there appears to be hope (my board is on its way already), any chance this additional driver info is documented somewhere?
There should be a pinout chart in the mini rambo wiki but you would also need to add the pins in the firmware.
Hey all, has anyone found a way to add the extra driver for the mini rambo? I would like to run the endstops but the rambo was out of stock when I ordered so I got the mini. The machine is working fine just would be cool to have. Thanks.
I would also be interested in the external driver setup
