Technique to Minimize Backlash by Gérard C.

Getting rid of backlash seems to be the biggest concern for the CNC hobbyist, especially when milling PCBs since copper traces for surface mount devices are used. Surface mount devices are very small electronic parts that contain leads that are extremely close together, or the leads are found on the bottom of the component and the part usually lays flat on the PCB (Printed Circuit Board).

Gérard C. has an interesting technique in solving this problem using two special nuts, one on either side of the MDF, to minimize the backlash Read More...
