Good idea to fix the blocks and let the rails move up and down on the z axis. Are they 4 way equal loading? Thats how I'm going to do it on mine. I would allow for a least a 1/3 of the rail to be held in the blocks. So for a 250mm travel you would need 375mm rails.

If its just for sign making then do you need so much travel? Why dont you just use the stand idea but have different size collars to rise it up in increments. Some people have also used multiple mounting heights on the z axis plate to allow for the cutting tool, might be worth looking at.


Yes but isnt that the fun part.
Yes i think the bearings are 4 way equal loading, they are adjustable as well, theres a close up picture of one in my gallery.

It is supposed to be for sign making and would actually only require about 10mm of z travel but i want to cut big things inside of it lol, i might not go for 250mm of z travel i think i will test it first, see how much flex there is.

I have ordered some 45x45mm box section and some more rails so i think i might try the make it up approach until i come up with some good ideas.
