Tools for QuickSwap Hotend assembly are very small indeed
@bob-nex Good to hear that you had no problems. I had them and tried everything that was mentioned in the manual to fix the issues. At the end it was a poor engineering choice for the assembly.
This is not meant as a mean comment, it's a critique that the devs should consider as a chance for improvements in the future.
@extrudercat Your suggestions are definitely worth exploring. However, for now we need to get you up and running with the parts you have on hand. Have you had any luck since?
You mention that the screws are too small to tighten, do you have access to a 1.3mm and 1.5mm hex drive?
@bigbrain3d Yes, the needed tools were here already. After some filing and sanding I managed to get the metal parts working perfectly, the nozzles are holding very good and tight.
@extrudercat Can you suggest the steps that you took, where and how much you filed, to get it to be smooth?
Mainly the corners had the most friction. I'm not totally sure if the black body part or the blank locking lever were not even, atm I don't have the tools here to check it. If I had to guess it would be the lever since it had a relatively rough surface finish.
The work itself was easy. put the underside of the lever on a wet sand paper on a hard and even surface and move it in 8-figures around to get a good result. Not necessary but beforehand I added permanent marker to see where material get's taken away.
The alternative could have been an uneven color layer on the black body part, but that is very unlikely since the part seems to be anodized which results in an evenly color surface.
