First Plasma CNC build with a cutting space of approximately 500*500

I would like to re0iterate my cunning plan for a floating-head:

Use a guided pneumatic cylinder for the float part, like:

Then you can use the cutting air to lock it down during cuts, preventing vibration triggering the switch.
These cylinders are designed to mount limit switches, so it is pretty much an all-in one floating slide already made.
 

Wow thats actual a really good plan. Have you already built one with these cylinders? Can you control the locking down with the LinuxCNC software? Also wouldnt it take longer to probe as tommy said? I mean if youre cutting something with a lot of holes it would take longer for the head to probe because it needs to push all the air out. Or am I overthinking it.

I know the pain same thing happend to me when I did my first post here directly removed the macro from my mouse so it will never happen again .

I will shorten the movement for the floating head. I´ve also added slot to tension the reduction belt. I tried fitting an idler bearing with a slot to tension the belt. But i dont really have that much space down there.

Steel didnt arrive till today. I hope it will get to me tomorrow so I can finally build the frame. If it arrives tomorrow I should be able to give you guys some pics about the frame built.
