Suggestions for improved documentation
Hi,
I completed a Delta stage microscope with basic Pi Camera v2 optics. I have a couple of suggestions on documentation that I hope can help complete beginners like me:
-
I found the o-ring install quite fiddly as many have indicated. This tweak worked much better for me as opposed to the assembly instructions for the delta microscope - by taking just the leg + o-ring + tool separately and aligning the o-ring on the tool tips as shown first and then installing in the base (picture below). The instructions ask to install the leg first and then use the tool to push the o-ring, I found it tends to engage on one end and not the other. https://build.openflexure.org/openflexure-delta-stage/v1.2.0/pages/index_transmission/pages/assembling_the_actuators.html

I could not find instructions as to how far the optics module needs to be from the slide. There is some discussion in the forum for the high resolution objective based setup, but not for the basic optics. It seems even in this case the pi camera lens needs to be close to a millimeter away. The issue is that there is an adjustment for mounting the optics on to the delta stage and if mounted some distance away, the z-axis will run out of range or reach the end of its range when bringing the stage close to the lens for focus.
