One Motor+Belt on Z-axis January 13, 2014 08:27PM |
Hi guys,
I saw a design like this. As a noob I'm not really sure how it works. Note that there's only ONE z motor.
I guess the guy pressed the belt pulley really tight with the nuts (and maybe even with threadlocker?) to try to keep it fixed.（maybe not）
Can anyone tell me if it's worthy to do so? Is it reliable at all?
Thanks

I built one that uses a single motor for the Z but I would suggest you need a very stiff guide rail system for Z and stiff frame not just one single ride per side preferably something supported all the way

You are a pro! I love your machine!
Absolutely a professional one.
But I don't get how did you handle you belts. Did you use two pulleys on the motor shaft?
My guess is like this:

Thank you I have just one pulley on the motor and one for each of the screws. So the belt is on a triangular path the pully on one of Z ballscrews has to have a nice easily adjustable pulley mine I made is a split collar design so you can adjust the two screws. The reason I did it in a triangular belt path was so you can move the motor to tighten the belt
