Plasma Attempt #2

[JAZZCNC]

Specially for Jazz I'm using unsupported round rail for the Y axis.

Nah for a skinny plasma with 30mm rails I'll let you have this one.!! . . . . . But all this Math or Arithmatic shit is making my crust hurt so just stick a bloody 3Nm motor on plug into national grid and watch the thing go like a rocket.!! . . . Don't matter all corners will all be circles and the thing will rip it's self apart trying to speed up/slow down and change direction unless you have a nice S-curve motion planner..

A common mistake for those who can't be arsed to do the sums. Like 200 lb plasma gantries for people who can't be arsed to test something lightweight. Like stepper motors to do torch height control because they can't be arsed to figure out how to set pierce and cut height without one. I am amazed how people weld up their plasma cutter frames with no thought of checking if they run true, my experience of welding says...
Weld oversize then cut it back to square because sure as eggs, it won't be
