Thanks Jeff. I like that idea. I'll see if that will fit. I may need to get a longer belt for that though cause the pulleys are 3.5" apart with a 13" belt.
I have an idea for the Z axis. Have a separate piece of aluminum that the stepper motor mounts to, with rods mount this to the side of the top aluminum block of the Z axis, [bore holes to fit rods in both pieces], make the stepper motor aluminum block slide on the rods to adjust belt tension. What do you think?:D
