Been running into a number of problems with the 3d printer recently, while I have been trying to create new terrain pieces for our gaming. The most notable concern has been a layer shift – at mostly random heights, the print seems to shift in the Y-axis, sometime plus, and sometime negative.
It isn’t consistent enough to cause a stair step effect, and it sometimes switches directions, depending on the print. But a number of the prints have ended up unusable as result.
Initially, I thought it was perhaps a loose belt (which did not seem to be the case), then I was thinking a heating issue. In particular, if I let the printer cool completely between prints, the shifting was less common or non-existent.
Then the problem worsened, and the print filament began to jam during the print. On further inspection, I found that the nozzle cooling fan (part of the original assembly) was no longer working. Fortunately, this is an easy and cheap fix ($3 part from Amazon), and a couple of days later, the fan was functional again.
Clear the jam and print another model – and thus far both the jamming and shifting problem seem to have been cleared out. Fingers crossed that this is a long term fix and the cause of the main problem.
