Belt connection on toolhead
January 23, 2023 07:14AM
That guy here says it's better to have them all on one side:

Yet, a lot of printers like the Ratrig V-core or VzBot have the belts arranged on the opposite sides on the toolhead.

I'm wondering what are the differences?

The difference is where forces are applied and the resulting torques. But since the carriage is mounted on a rigid linear guide and beam, it's not going to affect the position in any way that matters, so... meh.

If you really want to get picky about it, the tension on all the belts being on one side of the guide rail will be trying to force the rail to bend. I built a corexy sand table with 45 x 45 mm t-slot used for the frame and as Y axis guide rails (about 1.8m long). The belt tension caused the beams to bow outward.
