Good plan. And if that doesn't do it, low profile bolts could be used to gain even more space. The forces on the wheels are pretty tiny.Second gantries how about reversing the bolts? Nuts on the other sides?Head of the machine bolt on the bearing inner race. That will stop your collision.
Another small update:
Added some code to work with the scanner. And some hardware changes:
Counterweight is working. Motors can be turned off, no more whining noise:
All it took were some standard nuts:
I mounted the (bulky) arduino box:
And used a banana plug thingy instead of my protoboard to get power to the CNC shield:
It's starting to clean up nicely (for a prototype).
