-=== Rigidity + Backlash ===
+=== Backlash ===
 **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).
+Raw mechanical backlash before compensation: X: 0.08mm, Y: 0.06mm, Z: 0.16mm (Z does not have an encoder!).
+=== Rigidity ===
+To be measured...
 === 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)
+  * Z: 250mm (max distance from chuck face to vice top; you must subtract your tooling length)
-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.

 ==== Speeds & Feeds ====
-Always set both cutting speed and feed rate properly to avoid tool damage and poor results.
+See the Jaxen operating guide for details.
-  * You can look at the Jaxen Job Log for examples of past jobs so you get repeatable results.
-  * There is also a tool on the Jaxen CNC PC for suggesting RPM and feed rates based on your job. Name????

 ====== Maintenance ======
+For regular maintenance, see the Jaxen Operating guide. The following are maintenance projects that are identified to be beneficial in machine performance.
 ==== ToDo List ====

   * basic door on front
   * tramming, squaring vice, and other mill accuracy verification procedures.
+  * Add encoder to Z axis, change driver to A spare or get new driver that supports encoder feedback. Impact: there is currently odd behaviour in the Z-axis, which may impact it's accuracy. It's not known for sure whether this is related to lack of encoder.
 **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.
