Gerber Sabre 408 CNC Router

Overview

CNC router owned by Peter Schulert. It was bought in fully working condition, but the controls were modified to be run with LinuxCNC to support G-code rather than the proprietary Gerber files generated by ArtPath.

Circuit Breakers

There are four circuit breaker pertaining to the CNC router:

110V 20A 1-phase for the LinuxCNC computer

208V 40A 3-phase for the high frequency spindle
208V 30A 3-phase for the vacuum pump

relevant circuit breakers

Disconnect Switches

NOTE: the disconnect boxes contain fuses. These are redundant as we have circuit breakers, and it would be abnormal for them to blow. If you suspect they are blown, contact Forest Darling or Will Harper.

Table Control Box

There is a black control cabinet towards the back right of the router table, near the wall. On the back (side opposite most of the plugs) there is a small 2-pole circuit breaker. When off it shows an "O" but when on there aren't any visible markings. Here are photos:

Spindle Control Box

There is a gray spindle drive electrical cabinet between the right side of the router table and the nearby wall. It must have it's rotary switch in the vertical position to power on. Here are photos:
