right I have got the belt! well its ordered, cost a small fortune mind so I hope it won't break!

Yet another question. I am just fitting up the limit switches on the machine and then the homing.

I have the large industrial style limit switches with a roller that can be activated either cw/cww which I am going to have activated by a ramp rather than bumping into it. However the homing switches are proximity. how and where do people generally fit these?
