Ah - extra cheese :-)

The mini delta's are really noisy - but I don't think it's the board or the motors. Just seems to make lots of noise lol

BTT do have an awful lot of different boards - including clones of the duet boards.
What would you put in a prusa ?
Probably the skr turbo - it's got the dual z connectors, you could add the latest tmc drivers - all the way up to the super expensive 5's.
Still havent looked into how it works - but apparently you can do sensorless homing. I mean there has to be an endstop somewhere.
But it does allow the print to be interrupted and then reset and carry on where it was when it was stopped. Maybe that's what it means.

Anything tht can improve an ender is a good thing :-)
I'm all for improving them - just against them being sold in the first place lol
