My console is constantly moving. Saying <Idle|MPos:-11.205,48.644,32.135|FS:0,0> repeatedly. I’ve tried $$ and it does bring up the settings but, only for a split second, then I have to scroll up to find them.
Any help would be greatly appreciated!

Which GRBL version are you running?
I saw a CNC machine that had the same symptom.
Is your Jtech laser also a CNC machine?
I think, I am running GRBL 1.1g and yes, it is on my Openbuilds Lead 1515 cnc machine.
Flashing the controller back to 1.1f may be the fast way to address this.
There is an option during the firmware build that allows a periodic live update of position to appear on your screen. This option turns on a feature in the GRBL controller to relay the position information back to the computer console to update the graphic position on the monitor.
This may be a feature to support VCarve. Being Openbuilds they should have a Github repo with the source code.
1.1g isn’t an official build yet, so I’d be interested in seeing if I could see the option for live reporting in the 1.1g Source code.
Let me know if you can find the link to the firmware build.
Happy to help where I can.
Can you explain what you mean, when you said, “I’d be interested in seeing if I could see the option for live reporting in the 1.1g Source code.”
Certainly, Thank you for asking.
GRBL is an Open Source software project that allows anyone to use it.
Because it’s Open Source, part of the licence requirement is the ready availability to look at the source code.
The last official release is 1.1f and it is available here:
In the source code itself there are over a dozen features you can add-in or comment out (by removing punctuation and turning a note into a command - or turn a command into a note instead of executing it). This is done when a Firmware is being Built (or compiled) outside the controller and ‘Flashed’ into the controller from another computer where it’s being Built.
The important thing here is that in all official versions ALL the available options are present and readable - usually on a Github repository (repo) like the one above.
I poured through GRBL 1.1f but I found no option in it to enable constantly reporting the position back to LightBurn. I did find what looks like a position reporting time interval - but no way to adjust it after it is Built and Flashed.
Constant Position Reporting could be an Option in GRBL 1.1g and it could have been modified by your CNC device manufacturer to allow live reporting to their software package. They are totally allowed to do this. The licence requirements state that they are to share and publish the source code but I’ve found that several manufacturers have not done so.
I would like to review the GRBL 1.1g source code to see how Constant Position Reporting was enabled. There may be a new command to suspend the reporting - I don’t see it yet.
If there is a command to do the thing you want - It should be in the GRBL 1.1g documentation and source code.
If you can’t get this shut off, GRBL 1.1f would be the fall-back and you might be able to flash the controller back to GRBL 1.1f. However, if the GRBL 1.1g isn’t available it could be a one-way trip.
I had GRBL 1.1z on my Bachin Maker 5040. I have flashed it back to 1.1f and I’ll be making other changes and reflashing soon. The 1.1z and any undocumented features are now lost and gone.
I probably over-explained it but if you need more clarification I’m totally happy to help you get a handle on this.
