Prusa Research founder Josef Prusa addressed what he called “teething problems” with the Original Prusa Mini 3D printer to fans in a blog post on Monday, also discussing plans for the new year and recapping 2019.

The Mini, the latest offering from the 3D printer and filament manufacturer, was announced in October and began shipping out late last year.  It’s compact and boasts a lower price than the popular Original Prusa i3 MK3S, selling for $349 USD. But, despite the fanfare at its announcement and release (Prusa said it was one of the company’s “most successful launches ever”), some users have been reporting issues.

Prusa took the time to respond to these in his blog post, saying, “We already know what they are and how to fix them.”

Chief among the issues are the rotary encoders on the LCD panel, which have a “slightly larger than average fail rate” and “get stuck” after just a few days in use. Prusa said the parts would be replaced and that a “new, fixed batch is already on the way.”

Shipping woes also affected the new Mini. The MINDA mesh bed leveling sensor caused headaches for users because many found it was arriving “either misaligned or with a damaged cable.” Some even complained the “electronics box was cracked.” Though Prusa said the packaging is tested to prevent cases like this, he added that “it seems that sometimes the boxes get some really bad treatment, which is something we can’t control.”

The company has made improvements and modifications to these issues, said Prusa.

“Teething problems” aside, for those who have already managed to get their hands on a Mini and have been able to print with them, they appear to be thoroughly enjoying the experience. (Yours truly is still waiting on one, however, in case you were interested.)

Prusa also reported that a “web-based printer control system called PrusaConnect” would soon be available in the upcoming firmware update.
