Could you please upload 2D or 3D CAD files from the design software you used?
The STL files uploaded are great for replication, but mesh files aren't very useful for modifying parts.

The files 'Bearing Mount Right Top.STL' and 'Bearing Mount Right Bottom.STL' seem to be identical (and I think both the bottom).

I couldn't tell from the presentation or the github wiki or any of the READMEs if the raspberry pi camera lens needs removed or not.

Hi OpenLabTeam,

A while back a built a very DIY-friendly laser-cuttable microscope stage and arduino control app. It used very low-grade servos so the precision was poor, but it worked. I am mentioning it here because I would like to contribute it to the larger OpenLabTools project, if applicable (happy to improve documentation etc if interested).

Here's the repo: https://github.com/100ideas/ucam

Here you say to use a plano-convex, but the first image shows shows a biconvex, then the second shows the plano-convex (with the ray trace):

But here in the BOM you show a biconvex, which doesn't have the one planar side!

So what's the difference, and which is the better/proper one to use?

I hope you won't take this as negative feedback on an otherwise awesome project but i'd like to use this issue to identify some discrepancies with the documentation.

1. The Bill of Materials in the 'useful information' and 'step-by-step' guide differ for some important materials. Also using the BoM from the step-by-step guide will e.g. not get you enough T-brackets to complete the build.
2. The instructions for the linear stage towards the end of document require more specific instructions. From the text and the pictures it is still too vague how certain parts should be attached. Also is there a template for making holes into the perspex?
3. There is no documentation on the installation of the Arduino and/or RPi software. E.g. several Adafruit libraries are required to be installed. Also no mention is made anywhere of a Touchscreen in the documentation but the Arduino software requires a Touchscreen library. How is this Touchscreen used?

I may append to this list as i find more while i am finishing my build...
