 **Summary:** Space-made with DIY components; 1.75mm Filament, rather hacky; Hothead issues; Working pending head rebuild.
-**State:** Unused for some time and in need of a hot-head rebuild. Previously, the main board (Sanguinoliu 1.3a) failed due to over-heating problems at the PID hot-bed power output. The board's bed power FET has been bypassed with the 5v logic directly driving an external relay for bang-bang bed control. The XYZ mechanics are working but the hothead assembly failed due to it's plastic cracking. A replacement hothead assembly has been printed and new head purchased. The new head is wired in and is awaiting fitting into the replacement head assembly and fixing on to the X-carriage. Manual bed-levelling lacks precision, but is functional.
+**State:** Unused for some time. Head has been recently rebuilt using reprinted carriage head and new hothead [21/03/21]. Previously, the main board (Sanguinoliu 1.3a) failed due to over-heating problems at the PID hot-bed power output. The board's bed PID power FET has been bypassed with the 5v logic directly driving an external relay for bang-bang bed control. The XYZ mechanics are working. Manual bed-levelling lacks precision, but is functional. Recommend inverting the leveling bolt/nut and adding a 3d Printed knob to the nut for easier levelling (Like the Ender3).
 In order to be able to print, the following maintenance steps will be required first:
-  * Hot-head rebuild
   * Sourcing of power supply
   * Manual levelling improvements (ideally)
