As a last resort try removing all previous UGS settings (see property Files) and reinstall.Make sure GRBL is properly flashed on your controller.Make sure you have installed any drivers required for your controller.

Make sure you are connecting to the correct port.

Check the baud rate is 115200, or 9600 for very old versions of grbl.

Typically this is caused by a configuration problem and can be solved by one of the following: This happens when UGS connects to a serial port and does not receive the GRBL startup string. So to sum it up, I don’t know what broke it or fixed it but happy for now! Good luck.Common Problems 'Grbl has not finished booting.' I also use a high quality USB extension which has the ferrite core I added but eliminated this when trying to get Win11 working. My COM port is set on all defaults including 9600 baud and gSender connects at 115200. Note that both Microsoft and HP patches were applied in between the good and the bad for Win11 but didn’t rollback and assuming that was not the problem.įor Ardunio I have both IDE 1.8 & 2.0.

I assume the Ardunio changes made the difference but not trying anything or changing anything else and leaving well enough along. What I don’t understand is how Win11 could be impacted by EMI and Win10 and Mac was not. I added an extra ferrite core to the USB on the laptop end. I also made sure the USB cable was free and away from all of the others. I then read about EMI on the Longmill and Ardurino websites and separated all of my power cords from the other wires. On Win11 I uninstalled/reinstalled gSender, USB, Arduino drivers, etc. I had no issues with my other Win10 laptop or Mac laptop. Anyway as soon as organized everything I found Win11 stopped working. All of the electronics/controllers and power is wall mounted and wanted to keep those components away from the cutting so controller fans stayed clean. I had no issue when I was using Win11 during the MK2 build and initial setup but started having problems after tiding up the cables and including the laser. I am not exactly sure which of these worked but not going to change anything now. Hello - I had the same issue but may have resolved it through a number of steps on my Win11 laptop.
