Broken hearts? Top layer off of otherwise flawless print.
 

Broken hearts? Top layer off of otherwise flawless print.

I updated my MK3 to the latest FW and SLIC3R software last night and set to print six of these heart boxes. This morning I discovered all six hearts printed the top layer off center but otherwise fine. That heart shown on the top left was like the others. I broke it afterwards.

I am new to 3D printing (just assembled my kit last month) and am hoping for some guidance from this forum. Could this have been a software issue?

I have previously printed this heart as a single piece, and it was perfect. Also, I'd say about 95% of my total prints have printed with no troubles, so I am inclined to believe this isn't the result of poor calibration.

This looks like Layer Shifting... Have you read the guide on it here: https://www.prusaprinters.org/how-to-fix-the-most-common-3d-printing-errors/ ? It's the second section down...

Thank you. Yes, I had read that post but wasn't certain that was the issue. The examples I have seen online of layer shifting seem to occur more intermittently resulting in prints quite like the example shown in that link. In my case, the heart boxes completed as expected, and only the top layer shifted.

Likely, you're right, and I will troubleshoot. It's odd, however, as I have since printed two more objects without the slightest imperfection.

I've had it happen myself, and never worked out the actual cause as it often works the next time. The only time I got a reproducable shit every time was if I rapidly accelerated the print speed mid print. Other times I think it could be down to something knocking the printer or what it stands on (got any pets?), power fluctuations and EM interference...
