* This Machine has been retired, it was taken home during the HL2 => HL3 by a member. This was with the consent of the hacklab membership.

* Had repeated/ongoing LAYER SHIFT problems with a large "lot of movements" print.
** Snugged the screws to hold the plate on, as it was moving.
** Tightened the printhead gantry screws. Several have nuts pulling through, so '''need to glue that part of the printer'''.
** Retention both belts, by adding a printed piece onto each belt.
** Still getting some Layer Shifts, so will have to try 120mm/s travel speed next. (Instead of 200mm/s)
* Discovered the Print Bed Plate is no longer flat. (Small high area, centered on X-axis & bit behind Y-axis.)

* Connector Parts needed to finish other 2 Printheads -- and also to try different filament cooling fans.
** 3 pieces of:  https://www.digikey.ca/products/en?keywords=Wm1845-ND  (Have 2 of these.)
** 20 pieces of:  https://www.digikey.ca/products/en?keywords=Wm1837CT-ND  (Have 4 of these.)
** 8 pieces of:  https://www.digikey.ca/products/en?keywords=Wm1855-ND  (Have 2 of these. Also for cooling fan.)
** 50 pieces of: https://www.digikey.ca/products/en?keywords=Wm1841CT-ND  (Have NONE of these. Also for cooling fan.)
PLEASE NOTE: These connectors are '''extremely difficult''' to crimp in a manner they work. So at least '''double''' the crimp-connector parts are needed to get solid/working connectors.
