You may be interested in these links, it can reduce or eliminate the problems which require cold pulls. Basically the issue is that the tubing moves up and down during printing and creates a slack space where the filament gets into a region of the nozzle it’s not supposed to reach. This modification uses a short length of tubing inside the nozzle that is pushed down tight, then your regular tubing sits on top of that where the movement doesn’t cause any problems. I’ve never had a single clogged nozzle or needed to do a cold pull in several years since making this change, so I highly recommend it.

No worries, glad to help. I don’t print a lot with my machine any more, but things still come up (like I got a shop press a couple weeks ago and found a knob for the release valve so you don’t need a special tool for it … printed with no trouble and now the printer sits idle again).
