Addition A – Slave axis configuration example
With bigger machines you often need to use so called – slave axis. It is about that the physical axis of the
machine is powered by two motors.
We implemented in CSMIO/IP-A device the slave axes function with additional option to adjust geometry
of a machine. Geometry regulation is very useful if you want to set perpendicular axes precisely.
To understand the rule of slave axis configuration we will use a very common example
• XYZ 3 axis plotter
Transmission of a drive - toothed bars
•
X-axis (gantry) controlled by two motors both sides with pulleys.
•
Used phrases: master axis (main) and slave axis (slave).
•

Defining axes used in Mach3 program

In „ConfigPorts and Pins" menu, enable the X, Y and Z-axes.
Slave axes are A, B or C. We do not enable the slave axes here.
CSMIO/IP-A controller supports slave axis autonomously and
activating it as a normal axis may cause conflicts.

Axis scaling and configuration

We assume that the machine is properly configured like it was described in chapter 10. In „ConfigMotor
tuning" menu we only configure the Y-axis (master), slave axis is configured automatically. It is important
that master and slave axes have the same steps number per millimeter, so you cannot use motors with
different encoders or different pulleys.

Activation and choice of slave axis

Slave axis function is set in plugin configuration window –
„ConfigConfig PlugIns" menu by clicking on „config"
next to CSMIO-IP position.
In this example the axis that has two drives is X axis and
its assigned slave axis is B axis (A-axis is free, if we would
need a rotary axis in the future).
In „ Slave Axis Configuration" group we choose B as
„Slave", set the mode for now to „No correction" and „Ge-
ometry Correction" to 0.
