Turning a screw to pushes the target in the X or Y direction, and a load cell on each axis measures the applied force.

The purpose of this tool is to gradually apply a known force to a CNC router, so that the deflection may be measured as a function of applied force. (The deflection measurement is separate and not part of this design.)
This can be used as a diagnostic tool to identify whether a CNC router is performing as well as expected, and potentially to identify the weak point. It could also be useful when designing a CNC router to test the difference between design alternatives.
For the mechanical fixture you will need:
- Wooden base plate from plywood or MDF
- 8 M4 socket-cap screws for attaching printed parts to the load cells.
- 2 M3 screws and 2 M3 nuts for gradually applying force to X/Y stage
- Rubber bands to pull stage in X and Y direction (allows measuring push and pull forces with a single setup)
- Several #6 x ½" sheet metal screws (18 in total)
- 4 to attach base to underlying plank
- 6 to attach push/pull fixtures to plank (3 for left and 3 for right)
- 4 for attaching rubber bands to pull stage back toward push/pull fixtures (2 for left and 2 for right)
- 4 for fixing adapter plate to the platform (only 2 used in video below)
And to complete the system as shown you will need
- 2 load cells with HX711
- One OLED SSD1306
- Arduino controller like Mega 2560 or ESP32 should also work
- Batteries or USB connection for power
