Hey all, I have an Anycubic Mega-S, which I’ve had for 5 years now. I’m a very casual printer, but I’ve used my printer enough over the years that this problem is new, and confusing to me.

Last week I printed my tallest print (not the one shown here), and at the end, similar to the print shown, the cable and filament tube got squished up into the supporting bar at the top and caused the filament to not feed well and the print got a bit messed up at the end, but not terrible. The cord protector got a bit cracked even from being squished.

This print shown is not nearly as tall as the one from last week, and once again the wires and filament tube got shoved up into the top support bar and started to slow down the filament and cause the print to fail as you can see. This happened much earlier in height than last week. I didn’t think I’d run into the problem again with this one since it wasn’t as tall.

Thinking back to past prints I honestly can’t remember if the wires have always gotten stuck against the bar or this is a new thing. I haven’t paid that much attention before since it was never a problem. I added the last picture to show that the wires can just be pushed back on the other side of the bar and it would be fine, but this was printing overnight and was a day and a half print so I wasn’t here to manually push the wires back once it got high enough. I shouldn’t need to do that anyways though.

So, after all of that, I’m looking for help and suggestions on how to stop this from happening. Maybe thoughts on why this started happening now and it’s never been a problem before?

Thanks in advance!
