Hi,
I build a cnc router with ball screws and nuts from Ebay. Unfortunately, they did not come with any documentation.
I am also running servos with 14bit absolute encoders.
I have calculated my backlash and entered the values in Mach3.
When I calibrate my x and Y axis using Mach3, I have the following values per. x 6600.500932 any y 6602.946044
When test cut a 3.00 circle, it is 2.9850 in diameter.
What is the formula to increase .015 to make it 3.00 diameter?
Any help would be appreciated.
