Waiting for connection.
Good day i am having this issue when I maybe hit a soft limit alarm or any alarm if I then reset the controller there is no reconnection until I unplug the usb cable and re insert it.
I appreciate that you Copy / pasted the info from the Console Window. This is ideal! Thank you.
Please share the startup message from your GRBL controller.
It will convey the options that the is configured with and this may help us troubleshoot quicker.
Waiting for connection…

ok
this is when i start it before i reference home but say if i hit the softlimmit i cannot clear the error with reset.

reset just say waiting for connection.
can it be a compatibility problem as my Arduino and shield is not 1.1 compatible .

Please confirm that the limit switches are in place on your laser engraver and that the engraver, when powered up, proceeds with its homing operation by homing toward them.
Everything works fine homing works i can move the machine after homing it is just that when it give alarm i can reset it and then doesnt reconnect i have to unplug the cable and re insert
These are some pretty wild offsets. If you are using the coordinate system that your machine is designed for you can reset these to Zero and re-home.
Enter the following requests for reports and reset command in the Console window.
$#
$RST=#
$#
Pressing Enter after each one. Please copy and paste the reports there.
With an older GRBL, if you don’t have $30,$31,$32 for variable spindle (variable laser control), you may need to select GRBL-M3 for your device profile.
Good day thanx for the reply.
the problem is not the sizes or homing I can even burn an image in Light burn everything is working after i home it the problem is if u may jog to far to hit the software limit if I right click the device button it does not reconnect with GRBL I literally have to remove the the usb an re insert it. i have tested it on my other GRBL control software and the reset is working fine I have been using this machine and hardware for over a year and would really like to be able to use LB
Next time it stops and demands a reset,
Please test $R in the console window.
Another test of interest may be,
Right Click the devices button in the Laser Window.
Ok so what i have managed to do is made some changes to the grbl config file so that when doing homing the machine position and work shift position will be zero so no more offsets i think there must be something wrong with the origin setup because if i open universal gcode sender home it and set al axis to zero then open Lightburn everything works like a charm alarms reset no issues whatsoever but if I close light burn and open it again connection and everything works as soon there is alarm nothing resets and only hangs until I remove and reinsert the usb. only if i open my other software home and set origin then i can use Lightburn. so i have to open my other software home and set origin to be able to use Lightburn. none of the reset functions u advised help not even the set origin but work.
