I have NEMA 34 motors with STANDARD 14mm shafts. The rack and pinion drive gear is for a 12.67mm (1/2") shaft. What am I missing here?
Bummer.
The shaft diameter on my Teknic Clearpath Servos is 12.7mm. Seems there is more than one standard. But I am sympathetic because the Avid hole sizes for mounting the motors is M6 and the Clearpath Servos are M5. This is a particular problem on the Z-axis. I did NOT want to drill out my motors, so I resorted to using M6 to M5 Toyota Antenna Thread adapters. Sheesh!

The wonderful thing about standards is that there are so many to choose from.
My NEMA 34 servos have standard 3/8" D-shafts on them. They’re SO standard I have to make my own gears!
I found some 14mm gears with 5mm spacing from another vender.
Anyone needs the 1/2" gears, I will send them to you.
