"Origami" CNC Plasma Build - folding 1200 x 600mm cut area

JT - re the axis being perpendicular to each other I guess other than being careful on construction that next part is getting the racking on the X under control. Dual motors and independent homing with adjustable home reference points being key to that exercise?

Sounds like a good plan to me.

 A little progress this weekend.  Got the Y axis linear rails cut in between the rain.  Also printed these aignment jogs that I was shown bby a friend that he used on his hypercude 3d printer.  So after some looong print time as these are significantly bigger I have two.  And they work a treat. Instant alignment to within sub 0.06mm. 
Mounted rail


An alignment bracket
 

Checking how accurate it is to top of rail
 

Setting middle of rail to zero as reference point
 

Right then Left tavel check.   Pretty good at 0.02mm from zero.  In sweeping across the length and bearing in mind this is hot rolled steel with primer on it there is 0.05 to 0.06 of variation.  I would say that is pretty dang good given how this is all being put together.
 
 

I think a pretty good start to getting these rails lined up and ultimately in place. 

Cheers - James.

Getting things mounted up.
 

Good Work James,

Looks like it's really coming along now 

Cant wait to see the gantry on and how you go with the z axis

Cheers

Here are some draft images of a Z axis design.  I am trying to make as low profile as I can manage with components that are either readily available or not too challenging to create on a lathe or mill.

Cheers.

Check my Z build here, one set of rails needed for floating head is done with about 7 euro in material and it works perfectly fine:
