Pledge: CNC Mill

We are looking at performing a CNC conversion kit on the mill in the space

The item

No specific items have yet been selected. We might select individual components ourselves or buy a full conversion kit.

Specification

• Must be reversible - so that we can potentially return the mill in the condition that it was lent to us.
• Axes: 3 would be a good starting point.
• Max purchase cost: £?
• Construction: A kit solution looks best. Otherwise we'd need to machine adapters and various parts to couple the mill with the motors - harder still if we want to avoid modifying the mill itself.

Mill

• Loaned to the space by Nigle.
• The mill in question.
• This is actually a rebranded SIEG X2, which is an exceedingly popular mini-mill.

Potential conversions

• CNC Fusion X2 conversions - Kit #4 at $559 - excludes motors, controller. Requires no physical changes to the mill so can be easily reverted. This kit provides 3 axes of control with upgraded ballscrews - presumably to reduce backlash.
• KDN conversion kit.
• Plans for X2 conversion - Not free

Additional information

• Cutting sheet metal with a Sherline mill.
• Many mills to see at the London Model Engineering exhibition
• CAD_CAM_EDM_DRO yahoo group
• [1] various projects, including another CNC hack
