The RAVEN uses the scale sensors on the back roller to find the location of the back edge of the workpiece. To do this RAVEN moves the board out from under the back roller looking for the pressure to drop off, then moving back under the roller while mapping the output of the scale sensors.
The RAVEN is a servo system. That means that each axis has a sensor called an encoder that tracks the movement of the axis. The on-board computer commands each axis to move a certain distance over a certain interval of time and then compares the actual distance traveled (by reading the encoder) to the distance
The EdgeDetect process ensures accurate indexing of your board edges for the quick project positioning. This process will appear between the board positioning and load bit screen where it asks for the actual bit.
This is a detailed demonstration of how to cut curcuit boards with a RAVEN CNC router. The video covers making the jig, importing and laying out the board project, and cutting the project.
The RAVEN is a precision machine tool. With proper care and maintenance it will provide long, reliable service. WARNING: Always unplug the machine before attempting any maintenance on the machine. WARNING: If the machine is vibrating excessively and or making loud noises STOP and determine what is causing the issue. Continuing to run will result

Replacing the Z-Truck is occasionally necessary in order to to change bearings or replace the part. This video demonstrates the simple process of removing the z-truck. Follow these instructions to install a Z-truck.
The blades used are 2mm shaft blades. Most blades compatible with Cricut and similar vinyl cutters will work. These blades are inexpensive and readily available through a number of outlets including Amazon. BE AWARE: The blades with black or painted shafts will not work as they must be conductive to work with the touch plate.
