December 2020 – Santa is bringing me an AM8 (All-Metal Frame) for Christmas.
So it is time for the annual upgrade cycle. The major elements of the 2020 upgrade are:
The all Metal Frame, no surprises there then.
New Power switch and Earth the metal frame
Replace the Power Supply as it has started to whistle annoyingly
Relocate the Power Supply, fuse box and meters, BTT Display and SKR board.
Replace the Belts and new GT5 Pulleys on X and Y
Stick with SKR 1.3 but bring the Marlin up to date 2.0.8
Add a frame top Reel Holder for the filament.
Re-compile the finished SK1.3 Marlin for the SKR 1.4 Turbo back up board (but not install at this point)
