hi guys i have a cnc with grbl 32bits card with a katsu spindle for two years now. the spindle is powered by the relay present on the board and I have never had any problems. now all of a sudden the spindle stops during work and then suddenly turns on again, perhaps only for a few seconds before turning off again. The spindle works regularly if connected directly to 220v. in your opinion what could be the problem?
Thank you.
the spindle stops working during work.
Re: the spindle stops working during work.
I tried to connect the spindle directly to the cnc power supply and so I have no problems. at this point I deduce that the problem is in the output of the card. perhaps the relay. no one expresses himself?
