Pros
- Ball screws and 30 mm steel shafts keep it stiffer than belt and V-wheel starter machines
- Uses the same accessories as larger Onefinity machines, so upgrades carry over
- A 2 year mechanical warranty is longer than most starter machines get
- Open front and back lets you tile boards longer than the cutting area
Cons
- No router in the box, so budget for a 65 mm trim router or spindle
- Sensorless homing, no limit switches
- Needs a computer beside the machine to run jobs
