Hi everyone,
Thanks in advance for your help. I have a chinese modified 6040 that I have been using now for about 4 years with NO issues at all. Today going into the shop i soon realized that fro some reason my X,Y,Z,A axis are not working....The spindle is working fine but nothing else. I removed the cover to the stock black control box and noticed that it has three boards each of them having a power light but all three boards are linked to one another. ONLY the spindle board light comes on the other two do not. Any ideas as to what is wrong here?
