General Mach Discussion / Backlash problem, possible solution?
« on: March 03, 2008, 04:48:58 PM »
CNCers,
I'm having trouble getting my backlash compensation set correctly. I've used the dial indicator technique to do the x and y axis but this doesn't give me the info I need; I'm still off. Running a square and checking all four corners is tough with two dial indicators as the spindle is round and they get knocked out of the way as the cycle progresses.
What I'd like to do is put a fine grid on the table and use my spindle-cam to read where I'm at after a move in the x and y direction.
Does anyone know where to find an accurate indexing grid that won't break the bank? I've seen the ones from Edmonds but they are $250+.
I wonder if a plotter would print the grid accurately enough?
Any thoughts or ideas would be greatly appreciated.
Regards,
MM
