So whats the formula to get Mach to stop loosen the rails eliminate binding and tighten back down.??? . . . Your talking tosh and again passing on missleading vaguely accurate impracticle information which just sends wrong signals to newcomers who only discover this far into the build when it's too late.!. . . . End result being they can become disspondent and give up.

Much more helpfull to give sound advice encouraging good accurate build quality than saying just build it and don't worrie because software will compensate for your shity work.!!
Software compensation and formulas etc are last ditch work arounds which never work correctly or has desired.!!. . . . .Effectively they are weak bodge's not to be encouraged IMO.
