What settings are causing my homemade CNC router to engrave not as intended, but in a mirrored image? My CNC is controlled by Arduino Uno. The text is a simple text “Calvin” generated from the Easel text application. Any help would be greatly appreciated.
Thank you,
Calvin
You probably have you X-axis mirrored (unless there’s an option for mirroring in Easel?). If you have homing switches you’ll need to adjust your homing direction. You can then either power down and re-wire your motors to reverse movement, or you can flip the invert bit in Grbl
Setting the $2 in GRBL did it. Thank you so much.
I have some kind of the same problem. I have the 3018 cnc machine (banggood) but I can’t get it running propely. Some how, the image is mirrored and also upside down. I switch the 2 outer wires on the connectors of the z and y axis and it seems to work for the upside down issue. But still, it mirrors the jobs. Anybody have an idea? I also changed the $2 to 1, 2 and 3 but this doesn’t make a difference.
Mirrored = X travel in opposite postion
Upside down = Y travel in opposite direction
You need to swap one wire pair around to reverse stepper - or change direction in software.
