Hi Spot - depends on what accuracy you want? 50um? sub 1um? all possible. In regard to the pipe dream of moving things accurately without rails etc just because you may "know" where something is does not mean its actually there or does not mean it can follow the commanded path. You are walking down the path of satellite and rocket control and they still have mishaps. Control of non constrained dynamic motion is pretty difficult..... Peter

The lasers used to set up good machines are accurate to >1um run at >0.01um. 750um is 2B pencil stuff...

Managed to get 2 Chinese lasers good for 60um line width instead of the 40um of the greedy Americans for a 10th of the price. I am sure with good cameras instead of that 2B pencil stuff industrial cameras I can get better accuracy than a lot of commercial machines.

Made a lot of discoveries these last few weeks. Industrial CNC is a scam.....lol

And these collector welds are TIG territory because most of the time just merging the existing metal is all that is needed without any filler material.

Had a great career in aerospace, I am sure it will help me immensely
