extra stepper servo shield for rambo

by moleupnorth on Fri Oct 16, 2020 8:33 am

I have a Rambo 3 and it has all its stepper and servo channels in use.

Can I add an AdaFruit Motor shield(s), stepper and servo, to the Rambo and enable control of extra motors using Marlin

if yes, what pin connections on the Rambo v1.3

You might be able to get it to work, but it would not be seamless. The motor shield uses an i2c interface with a very shield-specific protocol, so you would need to somehow integrate the Adafruit library with your Marlin software. The interface pins for steppers would be SDA and SCL. Servo pins are a direct pass-through. You could use any free digital pin from the Rambo.
