 **As of 2026 Aug, with software backlash compensation enabled: users can expect accuracy of 0.01mm or better in X and Y.**
-Raw mechanical backlash before compensation: X: 0.08mm, Y: 0.06mm, Z: 0.16mm (Z needs to be investigated further).

 === Max build size: ===
-  * Y: ~130mm, see note below.
+  * Y: 130-180mm, depending on workholding.
   * X: 350mm (largest part size is larger: half the width of the enclosure)
   * Z: 250mm (distance from chuck face to vice top)
-Y axis increase plan:
-Move the Vice mount point backwards one slot to middle slot.
-Would also need to re-adjust the Y home position, since it likely won't reach it anymore.

   * tramming, squaring vice, and other mill accuracy verification procedures.
+  * Add encoder to Z axis, change driver to A spare or get new driver.
 **Non-Critical**
+  * Measure rigidity
   * Increase Y axis limit by moving vice, verify new limits and update specs.
   * Secure XYZ hard limits better, each only held with 1 screw.
