Creality Falcon converted Ender 3 - Reversed X Axis

[Flier545]

Hi, I finally managed to get my PC to communicate vie the serial cable

Only trouble is the Home position direction seems to be reversed

In transition after pressing home if I press the axis microswitch the transition stops. The carriage is clearly looking for the Microswitch signal to mark the home position but the switch is on the wrong end

I can’t see anywhere to reverse the axis

Thanks for your help in advance

Movie attached which hopefully explains it better than I can

Open the console in LightBurn or LaserGRBL, check the configuration values with $$.
Look for $3, it is a bit mask to invert axis. like 00000000 binary where the last bit inverts the X axis. If it’s 0, set it to 1 (decimal) then the X axis should be inverted. Otherwise you need to calculate the binary number to invert the last bit.

I can open the console but it does not let me edit the values

These are the console values

I’ve sussed out that by just pressing enter the values are updated. The bed also thinks the origin is at the front so this is probably reversed too. Which $ value do I need to adjust to set the origin with carriage all the way back as this is where the micro switch is

I need to lock the vertical movement of the laser so I lock it focus position. Currently the laser drops down and won’t stay in the same position. With the Falcon module there is no lead connected to the vertical stepper so how do I lock it in position. I have a 3D printer so if needs be I can print a locking bracket

$3 is set at 1 $3=1 this seems to have reversed the direction, is this what you would expect?

[s3sebastian]

Yes, and for the print bed direction, you could adjust the Y axis which is the 2nd bit.

Bed Quordinates

Open the console in LightBurn or LaserGRBL. Check current configuration with $. Find $3, which controls axis direction: 1 inverts X-axis (binary 00000001). 2 inverts Y-axis (binary 00000010). 4 inverts Z-axis (binary 00000100). To invert the Y-axis: If $3=0, type $3=2 to invert only the Y-axis. If $3 has another value (e.g., $3=1 for X-axis inverted), add 2 to invert Y too. For example, $3=1 becomes $3=3 to invert both X and Y. Send the command (e.g., $3=2) to apply the change…

You probably want to set the value to 3 then.

Thanks for that which seems to have worked

I have issues with the offset setting

The picture attached shows the image I am trying to print in lightbox but the photo shows where it is actually printing

I would like to be able to place an image on the Lightbox page and that is where it actually prints

I have the build plate size correct and have experimented with G10 L2 X- Y- but these don’t seem to carry forward from one cut to another

Also, have experimented with Offset setting in device/machine settings

Pressing home goes to the microswitch position but not actually the corner of the plate front left

Hope you can help

Thanks again
