# Troubleshooting the Jane loom **Shaft cord knot** - One of the most common mistakes when assembling the Jane loom is making an incorrect knot when connecting the shaft cord to the shaft end. The result will be a knot that slips and Shafts that slip downward with use, which results in a poor shed. Here is a link to Louët 's Support article and a short video to help. [Louët's Jane knot Support article](https://louet.zendesk.com/hc/en-us/articles/360051991873-Jane-Loom-Kombo-Loom-Knotting-the-Harness-Cord) {% embed url="" %} **Optimal Shaft Height** - This got a little trickier when Louet released their shuttle race. With the shuttle race attached, the original loom is too low to a table to allow it to fold correctly. Louet solved this by making the legs longer on all Jane looms. However, the manual still said to set the shaft height to 22.5cm from the table. That height doesn't work. The recommendation is to set the shafts just above the bottom rollers. If shafts are too high, you will reduce your **shed size**. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
