PIKA Test Grid after fixing X Axis Driver
Found the loose screw on the X Axis Driver. Re-doing the grid produced something quite a bit nicer. Still not perfect, but it's shaping up and close enough to proceed with some backlash testing:
Again, that's a 10x10 grid of 100μm squares. Line widths are a tad more consistent now I've fitted a temporary part to compensate for my mis-printed PIKA Z Tower, thus improving the probe angle.
Little divot in the bottom left is just me figuring out where the substrate is.
I could probably make a 1mm QR code...
