Engraved Text Mirror of Intended Result

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

4 ways:

  • Simply swap over the two pins from X-driver that is inserted into Ardunio UNO “Direction X-stepper” and “GND”
  • Locate one pair of the motor wires for your X-stepper, say A/A- OR B/B-. Swap around one pair only, reversing the A’s or B’s.
  • Edit GRBL parameter $2 which I assume currently =0, make it read value =1, in Easel Machine Inspector write “$2=1” and press Enter. Reset board.
  • Run Easel Setup which will guide you through direction etc. (This will reset all GRBL-parameters to default btw)

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.
