Standard on all EVO Sliders is a belt-driven system used by Rhino Flywheel and Rhino Motion. The drive shaft end plate includes a drive shaft as well as a pulley system which require occasional maintenance. If these items are not maintained it can result in calibration issues when using Rhino Motion.
The pulley, shown in the center of the picture above, connects the drive shaft (where the motor mounts) to the belt and lets the motor move the slider carriage.
To maintain your sliders drive shaft and belt system, we typically suggest following the steps below before each shoot or time-lapse to prevent issues.
First confirm that the belt pulley and drive shaft are tight:
Hold the carriage still with one hand. Do not move the carriage.
Twist the drive shaft (without the motor on it) with your other hand.
If you’re able to twist the pin without the carriage moving, then the pulley is loose.
If you are able to twist the pin without the carriage moving:
Locate the small hex screw on the pulley (see image above). The hex screw is just above the teeth that connect to the belt.
Push the drive shaft down towards the pulley as you tighten the pulley. This will prevent the drive shaft from coming loose.
Tighten the small hex screw using a 1.5mm hex wrench.
