Compact Machines version:compactmachines-4.0.0-alpha.6
Forge version:1.16.4 35.1.29
I am not using Optifine: correct

Description of the problem including expected versus actual behavior:
Personal Shrinking Device right or left click just doesn't seem to work at all.

This is not yet implemented in the 1.16 version due to large rendering changes. Added to the backlog.

Partially implemented in commit 95564af; sections are not fully in but the guide now works as one would expect. Will be resolved in the next mod release.
