My laser was working fine with LaserGRBL and then started testing Lightburn software. Everything was going great until I clicked the “Go to Origin” button. As soon as I did this, it kicked my Z axis motor into gear, went as high as it would go, then started grinding in place as it tried to continue to lift the Z axis. I had to kill the power source to get it to stop. I reset and tried again, I believe selecting the “Home” icon instead, but it did the same thing. Now it seems nothing is working. The board shows power, the computer connects no problem, but when any action is attempted, it shows the following:
Notice the X and Z positions right off the bat.

This indicates that X, Y, and Z limit switches are being activated. Can you move the laser head away from the switches while the machine is off, then try rehoming?
Tried physically spinning the spindles so the laser and the platform are in the center of the workspace, powered it back up, reconnected, tried homing, and nothing moved. Could the Z Axis error have burned out the board?
Here is the info with the commands you suggested. It seems like the issue is showing up in “[PRB:214748.3648,0.0000,0.0000:0]” with that wild X axis. I can’t figure that out.

I was hoping that the configuration that you posted earlier was just a copy error but that doesn’t seem the case.
There’s something corrupted in your firmware. It’s possible that it’s limited to the EEPROM but I wouldn’t trust it at this point. Is there a way you can reapply the fimrware for your controller?
Also, it seems to me that the firmware may be based on a stock GRBL firmware which would suggest an Arduino based controller type.
Do you know what machine/controller that your laser uses?
I used LaserGRBL to flash the board, connected everything back up, and the same issue still appears. In LaserGRBL the first message says “Check Limits” and the X value is still that huge number.
Hey, if anything, I’m learning a whole lot about the software and hardware through this nonsense! Thanks for the help.
Update to this. I found the $RST=$, $RST=#, and $RST=* commands and was able to remove all alarms from my system. The LaserGRBL loaded up just fine and was communicating with the board seemingly without issue. However, none of the motors are turning or moving the gantry.
It looks like you have what is essentially a 3018 Pro CNC with a laser. It’s basically the same machine I started with. Does your controller look like the one in the picture, and is it a CAMXTOOL V3.1? If you come to the conclusion that yours is beyond repair I happen to have an extra one that could be yours for the princely sum of $0. It’s in perfect working order (I upgraded controllers when I bought a bigger spindle), and if you live in the lower 48 I’ll mail it to you, if you want it.
That’s an incredible offer. I really appreciate it! I think I will have to take you up on that offer, since now the board won’t connect with my computer. Maybe flashing it messed something up? I’m so out of my element now. I liked error codes more than no connection at all.
