- This time we finish the X axis gantry, re-make the Z axis (again!), try to assess the quality of these cheap linear rails (link below), and get some movement!

There is no possible universe in which 0,03mm devation in X would have any effect on a plasma cutter. It's gonna be an amazing machine.
Agreed. I was really just trying to show how straight they were as they could be used for all sorts of DIY machines and at a lower cost. They are probably straighter than that as I’m at the limits of what I can measure. Thanks
Could be better if in the plate there are two little recesses for the bottom end of the springs
Agree but I had already made the plate before I decided to add the springs. I am planning to add some little 3D printed columns with locate and lock into the nearby clamping hole. The springs will fit over these.
I know you're a very precise person, which I very much admire, and your 'stuff' is absolutely incredible, I would never criticise any of your machines....but, can't help feeling you're going a bit complicated on this CNC Plasma over what is really required. Have you seen the channel 'Cranktown City'? (If you haven't, you should, the guy is a genius. Bit mucky, bit insane, but clearly a genius).
I have seen bits of his work. I struggled to stay engaged because I think we have very different styles! (no disrespect intended). I’ll have a look at his plasma build again though.
For your first point- yes I do enjoy the design and engineering process as much as the finished product.
@@routercnc9517 Don't take that too seriously, it's just a bit of fun. I think you both attack a problem from either end. There are many ways to skin a cat, as they say. Please don't skin any cats.
when cutting the upstands how did you ensure that, when in rough form, thee sides were parallel to the spindle?
These are extruded through a die so tend to be reasonably accurate. Good enough here where the sides are not references.
@@routercnc9517 maybe I didn't explain myself properly. I meant how do you stop yourself inadvertently machining a parallelogram rather than a rectangle i.e. the edges you machine are not perpendicular to the extruded side faces of the box section.
Oh I see. The answer is I checked with a square to make sure they were close but only the top and bottom surfaces are important. The sides do not reference to anything and could be out without effecting anything.
Cool project
Thanks. Happy with it so far.
