PRS Retro Z Axis

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.

3D Digitizing Probe

Works only with ShopBot and ShopBot Control Software

Make a copy of an object in 3D with our digital touch probe.  Attaches in place of your router bit in the router collet.  Place the object you want to copy on the ShopBot table and run the Copy Machine tool in the ShopBot Control Software. You can duplicate an existing 3D shape or a piece of decorative trim or molding.  Very useful for luthiers, furniture makers and restoration work.

The Digitizing Probe provides a way to create 3D files without the complexity of using 3D software because it can directly generate a ShopBot Part File as it probes.  Alternatively, you can generate 3D files for import into 3D software, which can then be modified or enhanced.

The Digitizing Probe can also be used to trace the outline of the edges of a flat part in order to produce a 2D file for cutting out copies of the part.

The probing time required to sample the object depends on the size of the object and how much detail you want to maintain in your copy.  Step distance can be set to as little as 0.002 inch depending on detail desired.  The probing process is not fast, but it does not require user intervention while the sampling is being done.  Once you have probed the part, you can efficiently cut an unlimited number of copies.

The probe gently touches the object during the process of sampling locations along the surface.  Its internal sensing is done by optical switches which provide accurate and reliable measurement over millions of contacts.  Output format choices are ShopBot Part File (.sbp), 3D point cloud (.dxf) for importing into design software such as PartWorks 3D, Aspire or ArtCAM and polyline (.dxf; 2D outline only) for importing into a CAD/CAM program.

3-Button Pendant Retrofit for PRS/PRTalphas

The 3-Button Pendant can be added to older PRSalpha/PRTalpha ShopBots and can be placed in a convenient location to allow ready access to the Start, Reset and E-Stop buttons.  The buttons on this pendant work in addition to the existing Start, Reset and E-Stop.  The 30' cord allows the operator to carry it to any location around the table, or it can be mounted near the computer controlling the ShopBot.  NOTE: Only alpha models can use this retrofit. [Download Installation and Use Instructions pdf.]

Z-zero Plate

Aluminum plate with wiring for zeroing the Z-axis.  Software program included in ShopBot Control Software will automatically establish an accurate zero for either the surface of the material or the surface of the table. Z-zero plate is wired to one of the Control System inputs.

(#14524) Z-zero Plate with cable; PRICE $75.00

Proximity Switches (X & Y axes)

Proximity switches are used to accurately and automatically zero the X and Y axes and as electronic limits.  The switches (non-contact inductive sensors; one for the X and one for the Y) are wired to a Control System Input.  They are easily added to your ShopBot.  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. Pricing here is for the pair of X/Y switches and cable, but single proximity switches for special uses are also available. Bracketing, targets and instructions are included in the kit.

(#14603) X & Y Axis Proximity Switches; PRICE  $225

Spindle Control Boards

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.

CNC Pressure Foot

Expand the capability of your CNC machine to cut "impossible" to clamp parts without using tabs or double-sided tape. Our CNC Pressure Foot™ attaches to the Z-axis of your CNC router or CNC milling machine and provides clamping force directly around the cutter - right where it’s needed the most. This targeted clamping approach is particularly effective for machining small parts and thin/flexible materials that cannot be held by traditional clamping methods (without using tabs or adhesives) including vacuum clamping, edge clamping, and screws or brad nails. .
