Hello
After building my cnc a couple of years ago with the help of the people of this forum I have a problem with the spindle .
The story goes like this
A couple off days a go I switched the spindle on and I thought I felt a slight tingle when I touched the frame off the cnc , I got my multimeter out and tested the frame for voltage when the spindle was running and I was getting a reading of it jumping from 30 to 100 to 160 the spindle seemed to be working 100% but then I realised that I had not earthed the frame, the cable was under the table but was not connected to the frame, I also found that the spindle had no earth wire, When i connected the earth wire and switch the vfd to run it would trip the trip in the house , I have checked the vfd and the trailing cable to the spindle and tested Ok , I have done a few test on the spindle and here is the video , Is the spindle faulty ? Any help would be much appreciated.
Cheers
