Hello
I have a chineese CNC router with a clone rich auto DSP since 2012( when i bought the machine I was a total newbie and had no idea that there were original and clone parts), it was working fine so far, but today having an issue with the spindle (water cooled) .
The problem is after powering on the machine the spindle starts turning immediately even at a higher speed that it normally runs. I can't even switch it off with the on/off button on the dsp. Have to shup down the machine for the spindle to stop. The X, Y and Z axes move OK even though the spindle is turning.
Have not made any changes in the DSP setting. In fact, did not use the machine for a few weeks due to health issues, and getting this problem when switched on the machine.
Any idea what could be the problem, any suggestions most welcome.
Thank you.
