Hi, sorry cant help with this, think your best option will be to contact LPKF and see if they have any info on repair shops they recommend.

Guess they may have the option of selling you a new spindle if you could fit it yourself? that could save some money and i'm sure we could help you with that if you run into problems, only info I could find was about fuse's.
