Comprised of an extruded aluminum Z beam and a captured bearing system, the Retro Z allows owners of older ShopBot PR and PRT machines to upgrade to a newer PRS-style Z axis. The PRS Retro Z Axis increases rigidity and tool accuracy in the older-model ShopBots and is a great way to rejuvenate a ShopBot’s performance after years of dependable use. The Retro Z is one of many after-market accessories available from ShopBot to improve tool function or help ShopBotters get the highest level of performance from their used or new ShopBots.
The PRS Retro Z Axis permits eight, 12 or 18 inches of stop-to-stop vertical travel and will not limit a tool's current travel in the X or Y axes. Multiple hole locations on the mounting plate allow for the Retro Z to be fastened at variable heights, and a corresponding motor plate is included to allow for the mounting of a customer’s existing Z motors to the Retro Z Axis. A PRS dust skirt is also included. At this time, dual Z configurations are not available.
When calling to order the PRS Retro Z Axis, customers should have the model number of their current Z motors and know the style – strut or single piece – of their Y car. PR & PRT Customers may also need a spindle or router adapter kit. ShopBot sales staff can answer any questions about Retro Z upgrades.

Software for doing the automatic zeroing of the X and Y is included in the ShopBot Control Software. When not being used to zero the location of an axis, they automatically act a electronic limits.

The Spindle Control Board allows the user to change the RPM of the spindle using ShopBot’s control software. The Spindle Control Board is wired into the variable frequency drive (VFD) and connects to the computer through USB. The device is controlled with SB3 (ShopBot Control software) through a virtual tool; Tools, Spindle RPM Control [TR]. The Spindle Control Board can control up to two spindles on two of the same model VFD; the VFDs should not be mounted farther than 3 feet (305mm) from each other. A jumper cable (SB#10256) is needed to connect the two VFDs. The Spindle Control Board is compatible only with ShopBot alpha and V4G boards using SB control software v3.5.6 or greater.
