 ====== TODO ======
   - Buy/trade more QC30 tooling
   - Buy a spindle with a through hole for a drawbar or have the original spindle drilled through - note that the CNC spindle is longer than a classic Bridgeport spindle, which won't fit
   - Add a spindle encoder using automatic car transmission Hall effect sensors using [[https://pico-systems.com/bridge_spindle.html|this guide]] as a starting point.
-  - Rebuild or replace the spindle CVT - it's worn out and damaged, makes the whole machine vibrate
-  - Replace the Bosch Z15-1A servo drive with 3 separate Copley Controls 423 drives (already acquired)
-  - Replace/modify the servo drive power section which currently provides 300VAC with a center tap for Bosch Z15-1A. CC 423 requires a single voltage DC supply instead, preferably 140V to match the maximum voltage of SEM MT30H4-44 servos
-  - Replace/supplement the Heidenhain TNC 131 control with Mesa Electronics 7i77/6i25 combo controlled by LinuxCNC. Keeping the TNC 131 as an alternative is prefereable to replacement, as it's still quite convenient for quick one-off jobs.
-  - Repair the oiling system and buy ISO68 way oil
   - Rebuild the coolant system, add mist nozzle
-====== RS232 link ======
+====== RS232 link (legacy Heidehein 131 controller) ======
 TNC 131 requires a standards-compliant RS232 link with hardware flow control (lack of DTR/DSR will prevent any communication), use a good USB-to-serialconverter. Prolific PL2303 has been tested and confirmed to work properly.
