Z Axis Stop Switch.

Z Axis Stop Switch.

Here are pics of the front/rear R7 Z-ganty plates, bolted together.

Note red arrows pointing to tapped stop switch mounting holes at top. Is this the correct location for the holes or do I need to flip the plate upside down before I mount on C-Beam?

Flip it upside down. The z gantry homes to max that way.

Thanks very much!
