I have been using the openbuild with grbl board hal 1.1 no problem. Came home after vacation :0 creaed some simple job in Vectric as usual. loaded the gcode, machines starts to cut and then it randomly throws Error 1, Erro 2 and Error 20 I started troubleshooing and found that, when the vfd is ON, ShopVac is ON, and Spindle 2.2KW is ON, I get the rrors no matter what gcode. However, when Spindle is Off and everythig else is On. I do not get error message and machines cuts air without any issue. I would appreciate if you can guide me on how to troubleshoot further. I know its related to Spindle, just dont know what to do next. Thank you as always. ps: all my cables are farret chokes, VFD power goes through an EMI filter. USB cable is shielded the setup ran without any issue for along time
