CNC Repair Service needed @Sydney northern beaches area

I'm looking for the CNC machine repairer in Sydney Northern Beaches area.

I have a Chinese Excitech SHG 1212 wood router with DSP controller.

I'm having problem with stuck Y axis.( not mechanically most likely electrical problem)

I have contacted some machine repairer but no one has any experience with Chinese machine.

Can anyone help ?

Thanks,

Taka
