G2S Optical Endstop and Cable Management

[Forrest]

After using this printer for a few days, I converted to optical endstop switch, which involved pulling plastic housing for Zmin connector and soldering a pin in the hole for V+, then using 3 pin cable to switch (along with modified mount for switch, and removing spring on trigger lever). Now works much more accurately and does not flex spider during G29.

This would be inexpensive to do to original design.

Also, need better cable management strategy for cable to spider ... so it does not pull it off center and cause jams?
