I am having trouble with my X and Y axis movement. anytime i go to move laser, it will only go to front/front left. (Note: My Z axis works great)
I started with $2=3, then $2=0, then $2=1, then $2=2 and $2=4 with no change to X and Y axis.
Before that I was messing with the $3, my start setting was $3=3 and in changing it, i realized the only change was my homed position. $3=3 is left front (where my homing should be), $3=2 is right front, $3=1 is left rear and $3=0 is right rear. So I left that as $3=3.
Still left with the axis problem with X and Y.
Z axis works great. Here are my current settings ($$)
Not sure where you got your information, but $3 is a direction parameter, not a location parameter.
$3 is for the Jog directions.
$23 is for the Homing directions, fix this one first.
It is probably best if you do a $RST=* to reset all your parameters back to the factory default and start over. Use the Lightburn Machine Settings window to make your adjustments. That way, you can flip one axis at a time without interaction with the others.
If you report what is happening as you go through the process, somebody can guide you along so you do not end up going in circles.Tell us what it is doing, and we can tell you what to change.
Sorry forgot to mention what happened after $RST=, so after entering $RST= my laser moved where I told it to but now that i go to frame, it goes to the center of the cutting board that im going to laser and then goes towards the front outside of cutting board all the way to front before its stopped by switches.

Reset while in motion. Grbl cannot guarantee position. Lost steps are likely. Re-homing is highly recommended.

OK, I closed out lightburn and reopened. Homing went opposite corner from where it should of (it went to right rear corner) then, I homed again and it went to right front (also the wrong homed corner). I only did the RST code and $X to unlock before homing reattempt.

Homing fail. Cycle failed to clear limit switch when pulling off. Try increasing pull-off setting or check wiring.

Absolute Coords has nothing to do with Homing. That is strictly a controller function.
Do not expect a magic cure-all with one diagnostic step. And definitely do not change any parameters without being told to. We need those parameters to be exactly what the factory restore provides. We shall go through a specific set of steps to get you back in operation.

HOME must be set up first. Place the laser module in the center of the workspace and power it up. Tell it to Home and tell me which corner it travels towards.
Trolley and gantry rapid move towards the switches.
When the switches are hit, the machine will stop and reverse. First Zaxis must complete if installed, then X and Y. It may not reverse X or Y until both switches are found for X and Y.
The machine will pull off the switches slowly until the switches open.
The machine will reverse back onto the switches very slowly until the switches close.
The machine will reverse and pull off the switches slowly until they open.
The controller establishes this as the Home position. It is usually shown as something very close to 0,0 as the position if the controller is set for the first quadrant. If it shows large numbers, this can be changed with the G10 command.
There is no other version of theHomecycle. If you have limit switches, this is how it should work.
If you do not have limit switches, where it powers up is the Origin. Home (red square) is a machine mechanical function. Origin (green square) is a software design position. They are not the same thing.
Thanks again. I’ll try this out tomorrow. In layman terms what does, “parameters” mean? What would it look like to change parameters (functions/codes in console).
I did a could laser jobs before and now I have a gift to do by certain date. It’s crazy how it all of a sudden stopped working.
These are numbers stored in the controller memory. They are used by the controller program (GRBL) so it knows some things about how your machine is built. If you make changes in your machine, you might change some paraameters to compensate. I hope my definition is better than Google.
You would just see a different number when you reviewed the parameters. This is no place to play unless you know what you are changing, why, and what the outcome would be. That was a hint.
Please use copy/paste from the Console window. Not everything in that window is showing, like the G54 settings. Also avoid camera shots of the screen because they are fuzzy and hard to read. Instead, use the Windows Snippy Tool (WinKey+SHFT+S) when capturing what is on your screen.
I cannot tell if it did or not. Withourt the entire Console window contents, I cannot tell.
In the Console window, right click and select Clear Console. Enter $$, which will list those parameters we talked about earlier. Now copy everything from the Console window and paste it in a Reply. Also confirm it did Home okay according to the information below.
Let us assume it did Home okay (see description below). The next step is to determine if the Jog directions are correct. Does the right arrow move it right and the up arrow move it to the back?
