    It was too hard for me to push it through completely, so i ended up and filed a little bit plastik away from the servo housing. I dont think that should harm it.

    Do not tighten too tight, it will bind the bearings. Make sure the Hotend Mount moves freely.

I may have missed it but i can’t find anything on how to attach the arm to switch extruders, i had to go to the store and look at the diagram for how to do it.

We’re still putting the finishing touches on the second part of the DSE instructions, we’re aiming to have it up by 03/04 at the latest (hopefully sooner). Thank you in advance for your patience.
