Roland mdx 20 milling machine fault

Hi i purchased a Roland MDX 20 hobby milling machine from ebay ... I was told it was in good working order but when I received the unit the milling spindle carriage is jamming this is jew to plastic teeth on on of the drive gears being worn out .... I tried to get my money back but the person has done a runner ( my own fault for being trusting ) anyway can anyone tell me where i can purchase a new or used gear in the UK please

Roland do still exist, and still make various CNC machines - https://www.rolanddg.co.uk/

However I have no idea if they'll still supply parts for older machines.

Hi, look up HPC gears, they will be able to sort you out as they can make any gear you need.
