[grbl Issue#1021] Install error.

#1 – chamnit 于 2016-06-21

@andsetinn : First, Grbl is not compatible with RAMPS. Second, CH340 USB-serial chips have known communication problems, which often result in lost data. (It doesn’t explain your connectivity issue). Third, make sure you are altering the config.h for Mega2560. Fourth, the Mega2560 is not officially supported by Grbl at this time, so you may run into problems. However, it should be working fine. Lastly, when nothing seems to work, disconnect everything from the Arduino and start simple.

Thank you Chamnit.
At the moment I don’t have the RAMPS shield on the Arduino.
I will look at config.h and see if that helps me with my problem.

@Andsetinn try the marlinkimbra repository

Thank you both for the help.
I tried old GRBL from EliteEng and now I get something on the Serial monitor. It´s an error but a step in the right direction. I will look at malinkimbra and others and try to figure out how to get this to work.

What are you wanting to use it for, laser? 3d printer? Mill?

At the moment I’m thinking of mill with the option of a laser, if I can buy one. First step is to get the electronics working. Then I have to design my own mill since I’m not fond of the most popular ones available at affordable price.
By the way, I programed an old Duemilanove and GBRL seems to work on it so the files I have are fine. Now I need to wait for smaller motorshield (and UNO) to arrive in the mail.
