Pulley Distances?

[astrodenny 0]

For the X-Y axes, does anyone have a general idea of what the distance should be for each pulley along the axis? How far away from the sidewalls of the frame, etc? I've checked the wiki, but it was not clear as to precisely how far in/out each pulley should be located along its axis. Thank you in advance.

the pulleys need to be position in a way that the belts are perfectly parallel above or under the axles

I suggest that good practice is to have the pulleys as close to the bearings a practicable - minimises bending moment on the shaft. You will need access to the grub screws which may be a limiting factor.

The comment in the previous post is the overriding consideration.

I don't think it matters too much just as long as they nor the belts dont foul anything.The pulleys are too close to the bearings to worry about bending moments.I just let the pulleys run loose over the rods while I moved the head around the table a few times, the pulleys just found their own position and I locked them at that.
