Hi,
another cnc router question regarding the lead screws for all my axis
my cnc im designing is 1000mm long x 750 wide, using 40 x 40 bosch extrusion and wood/aluminium gantry, but this may change yet.
anyway what i would like to know is what size ACME threaded bar should i be looking to use, would like as least backlash as poss, was looking at inch bar but not sure what TPI would be best and the was something about start up like say 4 or 8, will have to get back on that cant remember, also looked at the ball screws aswell.
any help is much appreciated as im abit unsure right now what to use
thanks
