Modified RapMan Z Switch

thingiverse

To resolve issues with Laszlo's Z switch holder, I designed a new solution where the Z switch is attached to the z stage platform rather than the print bed. This makes fine-tuning of the print-bed/extruder distance easier and uses an arm that presses the switch during the home sequence. Print the 2 parts, move the print head into the home position, lower the z stage slightly, disassemble the existing Z switch holder, assemble the new one with an additional M3 screw, find a good position for the new holder, attach it temporarily with double-sided sticky tape and test, drill 2 holes into the z stage platform at that position, fix it with 2 M4 screws, nuts, and washers, and finally test again. Check out the photos on my blog (http://blog.gagalabs.com/modified-z-switch-for-the-rapman-3dprinting) for more details.
