The NEW badge is for current owners of a JourneyMaker who wish to convert it to a Lemontron. The cost for the NEW parts is $29.43, plus another stepper motor. If you’re converting a JourneyMaker, you can re-use your entire tool head, so you don’t need to buy the positron one but it’s a big upgrade.

Total: $413.35
