I’ve been using the Sidekick 747 for a few months and the prints are great. However, last week I noticed that on the initial layer the hotend is lightly dragging, which is causing print failure. With the z axis raised there is a vertical wobble. This is not side to tside but up and down. The gantry wheels are a little loose. I have looked for instructions on how to adjust them but I can’t find any.
Ideas on what the problem really is or how to adjust the wheels would be very helpful
