Best regards:

If i turn the bottom of the lathe and set the speed to 300 (For example) Read the dro´s mach3 and try to adjust to 300 the difference it´s about 300=350, 400 rpm .The maximun preccission that i can make it´s about 10 -15 rpm (If the speed it´s 300 rpm i can make 310 rpm, i  only c3 index card and the disk to calculate the rpm)
Cheers and many thanks for you help
