The unit came from Zecoteck lab auction with a beam profiler mounted on it.  It was going back and forth fine until I sent it to end of limit where Gemini Ai could not get the venus 2 command to move it afterwards.  I decided to verify the individual cross over wires, got sloppy and spark occured.  The Pollux unit not longer responded to software commands.  (Probably 24 volts went down 5 v line into pollux brain and cooked it)  Gemni Ai is wonderful at finding commands one can copy and past to get something working but it will agree to a wrong assumption sometimes. 

I asked Gemini ai to describe unit

Detailed Item Description

Overview:Up for sale is a professional-grade PI Micos (Physik Instrumente) VT-80 Precision Linear Stage. This unit features an 80 mm travel distance and was originally part of a high-end scientific positioning setup.

Condition & Technical Notes:

  • Mechanical Stage (The "Good"): The VT-80 linear stage is in excellent mechanical condition. The integrated cross-roller bearings provide extremely smooth, high-precision travel. The lead screw shows no signs of binding or significant wear. This is a high-rigidity, German-engineered aluminum chassis designed for sub-micron resolution and high repeatability.

  • Pollux Drive (The "Cooked"): Please note that the attached Pollux Drive/Controller is non-functional ("cooked"). It does not respond to commands and will require professional repair or, more likely, a complete bypass/replacement.

Potential for the Buyer:This listing is ideal for a researcher, engineer, or advanced hobbyist who needs the high-quality mechanical precision of a PI Micos stage without the $2,000+ price tag of a new unit.

  • For Parts: Perfect donor for a VT-80 setup with a damaged rail or bearings.

  • For Retrofit: The internal motor (typically a 2-phase stepper or DC motor) can be rewired to a modern, inexpensive third-party controller (such as an Arduino-based driver or a ClearStep system) to create a high-performance positioning system for a fraction of the original cost.

Specifications:

  • Model: VT-80

  • Travel Range: 80 mm

  • Base Material: High-strength black anodized aluminum

  • Bearing Type: Precision Cross-Roller Bearings

  • Drive Unit: Pollux (Non-functional / Sold As-Is)

Shipping & Local Pickup:Located in Surrey, BC. Local pickup is highly encouraged to save on shipping costs for buyers in the Lower Mainland. For others, the item will be packed securely to ensure the precision rails are protected during transit.

Sold strictly AS-IS for parts or repair.
