Small update.
First of all I want to say that I am glad for two things untill now, first off all that I start to cut the plates from mdf and not direct on the 20mm aluminium plates.:D
And the second one is that I have those thick aluminium beams!
Warning, cover your eyes this build has nothing to do with what other guys post here :-P

NPN or PNP and what about the voltages those switches,the proximity works,I find a big difference in working current...

NPN = normally closed. Basic Amazon ones work fine for general homing / limits (around £7 each)
