The differences that matter
- Price: €3050 vs €2700 → the lathe has the same dimensions, so the €350 does not buy capacity.
- Capacity: 90 mm swing and 430 mm between centers on both → the two packages turn the same parts.
Which one to choose
Choose 8440 17" CNC Benchtop Lathe System (LinuxCNC) if…
Choose the 8440 if the LinuxCNC setup described for this package is the one you need: an Ubuntu computer with the driver board and power supply already fitted, while the tailstock spindle stays manual. The trade-off is paying about €350 more for a lathe with the same dimensions.
Choose 8440C 17″ CNC Benchtop Lathe System Package C if…
Choose the 8440C to turn under numerical control on the same lathe for less. The computer has the 4-axis driver board built into its chassis, but you must supply the monitor: keyboard and mouse are included.
