Addition A – Slave Axis Configuration Example - CS-Lab CSMIO IP-S User Manual

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-S 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-S 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 as 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 millime-
ter, 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 the 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
„Geometry Correction" to 0.
