Re: [CAD_CAM_EDM_DRO] Bport CNC Series 1 BOSS Quill problem

These are famous for getting fine swarf jammed between the quill an
dhousing. Usually next day when cool they'll move again, and you can clean
them off.

The next most likely thing is blown transister in that axis output stage.

Have had both these problems on Bports, so you can take me for an authority.
