FluidNC Controlling Delta Stage

$

Hello Everyone,

I recently built a Delta Stage and featured it in my latest YouTube video.

DIY Reverse Engineering Tools

I’ve really enjoyed using it under my AmScope microscope to view silicon wafers I extract from microchips.

I wanted to make the stage a bit more general purpose and lower the control cost a bit by using an ESP32 and FluidNC to control it. I’ve managed to get the Unipolar drivers to work and a Delta Kinematics module so I can drive the original geared motors without any modifications.

My question is on the delta kinematics themselves. I am trying to figure out the various lengths (f, rf, re, e) for use with other Delta controllers.

I read the paper and searched around but didn’t find anything except this post.

Regardless of whether you can help me or not, this is a great project and I’ve enjoyed seeing the precision that’s possible with low cost 3D printed devices like this!
