Im trying to make a drawing robot and I'm using an Arduino Uno with a cnc shield, however when I try to connect the Arduino to the universal Gcode sender it doesn't connect. I downloaded CH340 but that didn't fix the problem. Im on Mac but that shouldn't be an issue right?
here's a screen shot of what it looks like when I try to connect it.
if anybody knows how to fix this that would be great, thanks!
What code is downloaded into the UNO?
It needs a Grbl interpreter, not a blank UNO.
I had trouble also. I was on windows and I had to go into windows setup and manually disconnect the serial port then immediately connect it. It was frustrating until I figured it out. I am on a dual boot machine so I can't give you exact instructions cause I am usually on my linux machine. Anyways that is at least worth a try.
I Got the Grbl downloaded to the Arduino but it is still giving me the same result on universal Gcode sender
Check the Gcode sender setup. Is COM port set correctly?
You are trying to connect using baud 23, it should be 115200 or 9600 depending on the GRBL version.
