@mrfugu’s [solution](https://forums.maslowcnc.com/t/unistrut-frame-designs/1267/28) also does not require a chain guide, which I found really simplified my setup. It is the simplest and quickest solution to chain skipping that I’ve seen on the forum, and certainly worth a try if attempting to determine if chain skipping is the problem. The downside with the solution is that the roller has to be removed and replaced for chain calibrations as the chain cannot be removed from the sprocket while it is in place.
