Hello All
I built my machine with acme screws at first , worked good .
I then added ball screws and nuts from Mcmaster .Seems to be a bit sloppy now .Iam cutting flanges out of .5 acrylic .
My main question is , If I push on the x or y axis I can backdrive the screws pretty easy , Is this normal ? Where can I find anti-backlash ball nuts ,will this solve the problem?, Cant seem to get them from mcmaster .My table is 48x 36y is a 1/2 inch.5 lead srew good for this .
Thanks for the help .
