Exactly so best not to suggest anything.!! . . . There's a saying . . "Better to remain silent and be thought a fool than to open ones mouth and remove all doubt" . . . . . Not 100% relavent or possibly fair but I do like it. .Lol

And again you'd be wrong because servo's are not always better, The rails most likely over sized and screws wrong selection for this size machine without special considerations.

Well engineered, well built, and he lists what he would change
Again that would be wrong because it's a completely differant machine which would be inpracticle at this size required and totaly over engineered for cutting wood.

So again please I'm not picking on you just trying to show that throwing advice around without considering all the variables and relevancys can be disatrous for a new person.!! . . . . . . . I know this from helping many that have unwittingly fallen foul of such good intentions.!!
