Building a concrete 3D printer - need help with movement

Hello everyone,

We've been working on this for quite a while and finally all the hardware is set up.

We are trying to get Rumba + Marlin working now.
The control software we would like to use is Simplify3D with a custom profile.

Everytime we turn on the motors, you can hear the humming of the motors being energised.
But there is no movement when we try to move the X, Y and Z Axis. Even with the extruder motor, there is no movement.

We have already set Motor current limits (VREF) on the motor driver to 0.9
(Current limits = VREF x 2, the current limits for these motors are 1.8A)

Currently when we try to move the motors via the Simplify3D control panel, the voltage reading on the motor output is 2.8V.

I'm not sure what is going on but I have a few ideas.

1. There may not be enough voltage to the motors - how do we adjust that while still keeping within the current limits?
2. Microstepping settings on the motor driver - although is this were the case, I would assume that there would still be movement albeit it just would not be sufficient.
3. Jerk and Acceleration settings
4. Simplify3D Settings - Don't think Simplify3D is respecting the firmware settings. Is this even possible?

Here is a copy of the Firmware:

Here are the motors we are using:

Here is where we got our RUMBA board:

Thank you for the help in advanced! I'm fairly new to this and it's a project that we're just trying out at the moment!

Hi,

If the x, y, z axis are not moving but the motor are making noise, them it can be the problem of the lack of voltage or you need to increase the Amps of the steppers to something more of 0.9.
You are using big nema23 motors that work 24v to 42v, have you checked if the rumba board is providing the minimum 24v?
If the 4 cables motors are not correctly connected this problems happens too, check if each coil was the correct two respective cables...

About the extruder, the marlin firmware was by default an code protection that will only rotate the extruder motor when the hotend was the minimum temperature. Maybe this is your problem...

Jerk and Acceleration settings - all made in the configuration of the firmware.
