I have been spending a significant amount of time trying to fix the initial issue where the Z axis assembly is not square.
I finally found the right combination of screws to tighten and I am square in all directions. All distances and diagonals are perfect.
Rails are parallel and all should be great.
So I printed my test pattern but the Y axis seems to move too much making everything longer.
Ovals vs circles, rectangles vs squares and so on. Plotted squares have 100% square corners but are not even length.
I scanned the plot from the machine and overlaid it with the original in Inkscape. I attached the SVG.
What can that be?
Thinking about setting a variable for the multiplier to scale the Y axis down.
