Building a 3-axis plasma table with mesa 7i96s, THCad-2 and nema23 steppers

I've decided to immediately apply a 1:3 reduction ratio, which translates to 25mm (15T) or 20mm (12T) of displacement per revolution.

I want to listen to the advice of  rodw and  tommylight

This will change the design somewhat. I think I'll place the linear guide directly on the underside of the tubes to reduce contamination.

Slowly, all the parts are arriving, and I've started welding the table. Unfortunately, I have limited time

For now, I think I'll test it this way.
Later, I can make a support from cut aluminum plates.

I've also ordered the plasma source.
Any other tips and tricks?
