MK3S nozzle not aligned with thumbtack in purge mechanism
Just got my parts in the mail (USPS is slow these days!) and assembled everything. Is there a way to adjust the RPM in the Y-axis direction. The nozzle on my stock Prusa MK3S seems to be several mm forward of the thumbtack, so when I attempt the purge blob test, the filament just pours through the mechanism to the build plate.
Actually, maybe not. I had to reprint the catcher and cage because I couldn't get the cage back off to reinsert the washer. Tried again, and the same thing happened. The filament poured onto the edge of the washer, I think, and then down to the thumbtack, but then when the mechanism attempted to eject it, it dislodged the washer again. Is it possible to get a right mount that's somewhere in between. Or if you have the model file, I might be able to experiment with various sizes.
Is there a trick to getting the washer seated again without having to remove the cage? Or a trick to taking the cage off without breaking it? (Thank you for including extra kapton and foil tape in the parts, BTW!)
Thanks again @bigbrain3d. The 2mm seems to get the nozzle into position. The blob gets formed on the thumbtack. But when the mechanism ejects, it still has a tendency to grab onto the washer, dislodge it, and then jam the ejection mechanism. Do you have any suggestions? I'm thinking about just supergluing the washer into position.
The Blob should form under the washer. It should not stick to the washer at all.
Could you attach a video looking from the front-underneath so I can see what is happening?
