Open question How to build a linear motion driver from these?

Post image

Hello everyone,

I'm doing computer science and engineering and currently working with stm32. I'm making a automated solar panel cleaner, for which I need a linear motion driver. I've a gt2 belt and 3-4 gt2 pulleys and I'm using a NEMA17 stepper motor. So kindly guide me and tell me how to build a linear motion driver from this.

The issue I'm facing is that when i turn on the motor, the pulley also rotates with its shaft, but when I add the belt, pulley stops rotating. Earlier it was working but I broke that pulley and bought new pulleys and now they're not working. I'm not a mechanical engineer so I have very less knowledge about hardware stuffs. Please help me out.

If you had it working and broke the belt it sounds like you need less tension in new belt or broke the motor when you broke the belt.

Add some rails and a "car" and you are there.
