Two Trees Sapphire pro 2 - exploring this corexy printer

[curious aardvark]

Okay - she lives !
Properly - or as much as will be for now :-)

I changed the firmware to a custom version a guy made.
Looks nice, has one button load and remove for the filament - which I like.

Fixed the temperature issues - done a couple pid's and updated and saved to eeprom viz g-code and the simplify3d control panel.

Added a micro sd - full size adaptor and prints are now working from the sdcard.

So it's properly functional.
Dimensional accuracy is excellent.
Did a 25mm cube at 150mm/s - great :-)

So I'm currently doing a more comples print. A print in place folding phone stand.
It's 2mm thick and has 6 hinges. Great bit of design.
not as tricky as an iris box, but still a good test print.

My only decision mow is whether to change the 0.4 nozzle for a 0.5.

And grease the z rods - it's developed a 'squeak' lol.
