I tried to calibrate my x-axis movement, and after I put in how many mms the laser traveled, my laser does not home and it only moves opposite of the direction that I tell it to in lightburn.
Where/how did you change these settings, your profile says GRBL machine, is that correct?
Do you have a copy of your settings from before you changed them?
Can you post what you get by typing $$ in the console.
I found a setting where you draw a 100 mm square and after the laser burns that, you take a caliper and measure the exact distance that the laser traveled. I believe it was a little more than half the distance that it was supposed to travel. In the settings you input how far the laser actually traveled. Since then, my B1 40w is now making the top right the home settings, and the movements are reversed. These are the codes that the console brings up when I type $$:

Grbl 1.1 [‘$’ for help]
Your Grbl may not support Variable Power mode (M4)
If your laser does not turn off between cuts,
switch to the GRBL-M3 device

Unless you are familiar with the GRBL parameter settings, it is best to do it using the Lightburn Machine Settings window.
- It lists the function of each parameter so you will not be changing the wrong one.
- I splits $3 and $23 (and others) out into separate settings so you are not changing X while you are trying to change Y.
At this point, you need to restore your controller back to the default settings. There is a procedure for that too.
I’m a little confused, fine-tuning steps has nothing to do with home position or direction change. You must have changed other parameters without realizing it.
Have you saved a copy of $$ ?, roll it back and start over again.
If you don’t have an overview of your standard settings, I have a copy from a Longer, but it’s a bit old. If you don’t have anything to compare your settings to, I can give it to you.
There have also been a few threads here on the forum with similar problems, try searching for Longer GRBL…
What are the steps to bring the controller back to default. This has been incredibly frustrating and any help is very much appreciated.
I don’t know why after I did that calibration adjustment, but as soon as I did that everything started going crazy. If you have those settings, can you send them over. Any little bit helps. Thank you

Here it is, be careful and document what you do/change, so you can always go back
Cannot help you here. All my machines are Sculpfun and would be useless for yours.
Most GRBL controllers will restore the factory default settings by entering $RST=* in the Console window.
BEFORE YOU DO THIS, enter $$ in the Console window. Then copy everything in the Console window after the $$ and paste in a properly named text file. Put that text file in a safe place. You will need it in case the factory reset goes nuts.
Let us know how it turns out.
