Limit Switch Mounting

Post by JRDM » Mon May 12, 2014 1:36 pm

I'm getting closer to connecting a TinyG to a Shapeoko 2.

I've seen some examples for X & Y limit switch locations, but I haven't found anything for the Z limit. Can anyone post or point to posts showing some user's Z switch mounts?

Thank you.

For my Z home switch I printed one of these switch holders that screws to the maker slide and it works great.

I printed an extra as I was going to do min/max limits but decided to only do homing switches with my tinyG controller I would be happy to throw one in the mail to you if you are in the US.

OK.

Thank you for the offer. I'll probably print my own and see how it goes.

The X and Y seemed to have good mounting examples, I just didn't see anything for Z axis.

I milled something similar out of HDPE. mine comes off perpendicular to the one posted and triggers on the spindle mount plate.

I was looking for an upper switch mount, I couldn't find one that fit what I wanted, so I designed one.

The odd offsets and such allow me to place the switch so I don't needlessly constrain the machine's travel. I can adjust it a bit higher on the extrusion, I just haven't yet.
