[gnea/grbl-Mega Issue#126] Serial comunication problem

#1 – fra589 于 2020-06-09

Hi @EragonPower,

I recently have a similar issue on Windows 10 with an update who break all USB devices
cf. https://answers.microsoft.com/en-us/windows/forum/all/windows-10-pro-1909-breaks-all-usb-devices/33caa74b-a0bc-4389-a608-804c2099d170
Perhaps you can search on Google, it seams that it’s not the first time this appear…

The problem is that I’ve tried on a win 10 and a win 7 machine and nothing seems to work, I’ve even tried writing some code to test to test the serial read and write capability and everything worked, I think that there are some problems with my Arduino and the way that GRBL uses the serial comunication. Those problems manifested after powering up and using a VFD in a nearest electric cabinet so perhaps some magnetic fields may have damaged my Arduino but I’m not shore how, because again, the serial comunication works just fine except with GRBL

UPDATE: i managed to upload the .HEX version of GRBL on the arduino and now everything works

PS: after finding the solution I found the problem, arduinoIDE was not loading the GRBL-mega library, but rather a GRBL library that I had modified which had problems, after moving that corrupted library everything worked perfectly.
