I have written a Custom Firmware for the Vigotech VG-L7x to directly control GRBL. The controller has in this case a ESP32 which forward all command coming from the USB Serial Port to the m328p.
It is a simple serial bridge.
Source can be found here:
It runs stable with all tested softwares (LaserGRBL, Visicut,…) besides Lightburn in buffering mode. Looks like the is a bug in detecting the buffer load. I already optimized the speed of the connection. It helped a bit but seems that Lightburn overload the buffer until the connection fails.
The usb cable and so on can be ruled out because it is working fine with the other apps.
Is there a way to debug the connection?
