Hi everyone, I am newbee on cnc and grbl. I buy CNC3018 Pro. It come with Woodpecker 3.2A control card. I connect probe pins to A5 and GND. When i touch probe GND to spindle, spindle runs. Now my card not communicate with usb and offline controller. I think one or more components burned but i dont solve that.

I buy CronosMaker CNC Controller card from AliExpress. This is link: https://www.aliexpress.com/item/CNC-3018-2418-1610-3-Axis-control-board-GRBL-Offline-Controller-board-Laser-board-for-GRBL/32866461881.html?spm=a2g0s.9042311.0.0.35514c4dITool4

Today, i connect probe pins and when i touch probe's GND cable to spindle, spindle runs. Now this card not respone to usb and offline controller.

I just purchased the exact same board I have traced an issue that the ground is Hot and the Positive is grounds, i tried wiring it so that hot is going into the laser module correct, and the ground is correct, and that Blue PWM is matched, i merely plug in the usb no power and the laser is on and the fan is not and i have kept it while hitting the on off function there is no communicating, this board say grbl 1.1f but I have other that say the same 1.1f and I am having trouble with them all
