Two Trees Sapphire pro 2 - exploring this corexy printer

[curious aardvark]

It Lives !
And oh man is it quiet !

The only noise is the tiny fan in the base and the occasional retraction.

The linear slides on the x&y are silent as are the tmc driven motors.

The odd thing is that while I've now got it talking to simplify3d and happily printing over the usb cable.
It won't print the same g-code from the sd card.
It reads the card and appears to load the file a the hotend and bed heat up correctly.
But doesn't go so far as to home and start printing.

Wondering if I can plug an sd card reader into the screen.
Although it does read the card.
odd.
And a problem for tomorrow.
Yonight I' going to ramp the spee dip and see just what this sucker will do !

Also try and figure out why the fan control isn't working.

There are only two sockets for the c]print cooling fans. And the control panel has fan speed options that don't do anything.

Maybe need to swap over and double wire the fans into one connector.
we'll see. Also try a different sdcard and a micro to standard adaptor.

And sort the bloody hotend temp swing.
It's goes from 10c under to 20c ver and oscillates between.
Never seen anything like it.
The hotbed just hits temp and stays there - like normal.

Have to see what gcode I can throw at the robin nano to try and settle things down a bit.

But I am up to 200mm/s print speed.
hell I'm printing the first layer at 100.
I've aset everything else at 100% and just given the first layer 50%

Magigoo is good stuff lol

That was the problem I had and without the knowledge to know what was wrong my best choice was to sell it to someone who would get it working.
I'm happy it's done you some good.
