Prusa Core One+ Gen 2 Is Here: What Owners Need to Know

What Changed

Prusa's Core One+ Gen 2 upgrade landed quietly in late August, and the livestream showing the install went out on September 7. The changes are modest on paper but meaningful in daily use.

The headline items: new GT1.5 belts replace the older GT2 belts, a nozzle wiper is now built in, and the heatbed mounting gets expansion joints that cut down on the annoying heat-soak step for materials at 85 degrees Celsius or lower. Prices did not move. New orders ship with the Gen 2 parts already installed, and anyone with an existing Core One+ gets the kit for free.

That last part matters. Prusa could have charged for this. The company chose not to.

The Belt Question

The move from GT2 to GT1.5 belts sparked questions in the Prusa community. A tighter pitch means smaller teeth and, in theory, finer motion resolution. Several early testers noted smoother surface finishes on curved geometry, though the difference is subtle enough that most users will not spot it on functional parts.

The nozzle wiper is the change people will notice immediately. Purge strings and occasional ooze on the first layer have been a known quirk of the Core One since launch. The new wiper catches that material before it becomes a problem.

Who Should Care

If you already own a Core One+, order the kit. It is free and the install takes about an hour with the guide on Prusa's knowledge base. If you were on the fence about buying, the Gen 2 changes close the gap between the Core One+ and the larger XL+ in a few areas, particularly print start speed.

The assembled Core One+ with Gen 2 runs $1,449. The kit version is $1,149. Both ship from the US facility.

Prusa also confirmed the INDX toolchanger version with Gen 2 is now shipping as a complete assembled unit starting at $1,999 for the four-tool configuration.

Our Take

This is how product refreshes should work. Prusa upgraded three printers in one pass, kept prices flat, and gave existing owners the improvements at no cost. It is a rare move in consumer hardware, and it builds the kind of loyalty that keeps people in the ecosystem.
