Hey all, just spitballing the idea of adapting the worm gear that moves the head up and down to an electric motor to save my arm some cranking . I was thinking some kind of gear motor with adequate RPM would do the trick. The worm and spur gear that come with the machine have a gear ratio of about 15:1 or 16:1, just eyeballing turns of the input to turns of the output. The main thing I'm having trouble determining is how much motor torque would be adequate for this application. My idea was to attach a torque wrench onto the shaft somehow and use it to measure the breakpoint for rotation in lb-ft. I saw pics of users who have done similar builds but info about the motors themselves seemed sparse in the specifications department.
Something like what user TomS did in this thread is what I had envisioned. Just not sure what I need in terms of power to make it move!
Advice for DIY Z Axis Power Drive
I’m investigating adding a Z axis power drive to my Precision Matthews PM30-MV mill. I was looking into motors, and had some questions regarding what type of motor to go with. Based on people that convert to CNC, it looks like I can get away with a motor rated at 900oz per inch or greater...
