GRBL 1.1F ERROR WHILE PROCESSING RESPONSE (EMERGENCY HELP)

[ipsum-coder]

I am currently making up a cnc aurdino pen plotter working upon grbl 1.1f and it works completely fine until an error pops out of nowhere and the servo motor stops working. The aurdino,connections and usb all are genuine still this error pops and it stops.

**_Error while processing response <<Run|MPos:93.650,119.610,0.000|F:76Pn:PXYZ>>: For input string: "76Pn:PXYZ"_**

I need instant support if someone can help me
the ugs and grbl are up to date versions

So you weren't happy with my answer over at UGS?

I don't think that you will get a better response here. Can you post links of the hardware that you bought?
