That kinematics layout worked well for me.
I ran into a few other issues that might be worth noting:
I am getting a weird line down my part, but I think the probe X-axis on my rotary is wrong by about 1.5mm. Cutting a hole from both sides of the stock shows a clear misalignment. I was able to fix this by adjusting the X offset for probing by a mm or so from where the manual says to put it, but I still get lines in my cut, so it might need more calibration.
I had one cut where the Y was clearly wrong after changing tools (about 2mm high). I think there was some dust on the tool setter and the height was set wrong on the tool change. The rotary is very sensitive to calibration errors as indexed cuts end up misaligned.
X offset is slightly wrong (line down part every 90 degrees):
