Please help🙏Upgraded to 1.5kw 220v spindle and having disconnect issues 😭

Arjan raises a good point, checking out the grounding is a good move as you have the interference issues, here’s a guide and video about that;

Grounding your Shapeoko

Why would you want to ground your Shapeoko? This isn’t something everybody should do, but if you have either of the following issues, you should consider it; Dust & chip accumulation (on rails and V wheels causing movement problems) Random disconnects (when cutting plastics or when extraction is on) There’s nothing ‘wrong’ with the way the Shapeoko is delivered and there’s no safety issue WRT grounding on the machines (if you add a VFD spindle that must be properly grounded but that’s not for…

VFDs inherently make a lot of electromagnetic noise, especially on the output between the VFD and the motor. These cheap HY units also send a lot of noise back into the mains supply (thus the interference filter on the input which you ordered). I have a shielded cable, both foil and braid shield which is grounded at the VFD earth, it seemed like simple insurance.

Your routing of the VFD cable away from all the others is a good move, one I’d endorse even with a shielded cable.

As you’ve connected the VFD to the Shapeoko controller you have the possibility of a ground loop and much harder to resolve interference due to that. I’d suggest getting the VFD to work using the control knob on the front panel and trying it without the connection to the Shapeoko. You may need to move the jumper on the board, there’s also a setting to tell the VFD to use the built in control (PD002 I believe). On mine you can turn it down to stopped so try turning the pot clockwise too.

Be careful with PD0013, you can burn out the VFD or motor with the wrong settings and the factory default may well not be ‘right’ for your setup.
