After selecting the threaded rod or ACME screw you intend to use for linear motion, you need a way to effectively connect this rod to a stepper motor such that there is zero slip when the motor is rotating. I’ve found a number of articles about this subject, but I’ve found many of them give […]

May 2nd, 2011 admin Threaded rods vs. ACME rods There are many methods of accomplishing linear power transmission, otherwise known as linear movement. Anything from a simple wheel, to a gear on a rack, to rubber belts will work. However, for hobby CNC machines, the most common method to accomplish movement is using threaded rods, or ACME rods.
