I believe that is the exact process I go through, but like I said earlier, I am an extreme novice at Lightburn, so I could be doing it wrong. I enter $$, and the $10 setting shows that it is =0. Before opening Lightburn, I close Carbide Motion, then open Lightburn. Once open, I click on the Use Laser Macro and the machine homes. After that, everything goes wrong.
The machine will not jog correctly nor allow me to define a workspace.
WOW!!! It looks like the instructions worked. After resetting the GRBL again and homing, I can now jog my machine correctly. It homes to the back right corner as always, but the Z-axis still does not work so I cannot set the laser height. We are making progress, though. Thank you.
Ok, I am obviously doing something wrong because it is back to only moving in one direction again. Should I enter $RST=# into the console each time I open Lightburn? Is that something that could be added to the macro?
The GRBL was reset and everything but the Z works, again. When I push the up or down buttons, nothing happens. There is not even anything in the console that acknowledges that a button was pushed. It is as if I am not doing anything at all.
In console type $HZ
where does the laser moves?
No need to do that, just checked and your PLH3D-CNC Adapter Pro works with PWM so keep your device as GRBL.
DTR is to help when there is problematic comms (by Device needs).
I am not at all sure what it means to setup a device as GRBL-M3 but I see you checked on it. As far as the $HZ, here is the result:
$HZ
error:8
Grbl ‘$’ command cannot be used unless Grbl is IDLE. Ensures smooth operation during a job.
The manual says the Network Port setting is in the bottom right of the Device Settings window, but I cannot find it. Nowhere on the Device Settings page do I see network port settings. In fact, there is nothing but a blank area at the bottom right of the page. If I am looking in the wrong place , please let me know.
Everything I read talks about a USB connection but apparently, Opt Laser and Carbide Motion do not play well together so the connection has to be made through direct pins to the PWM/GRND pins on the board.
Set to synchronous with the following result:
error:3
Grbl ‘$’ system command was not recognized or supported.
Should work, Lightburn just send commands to the controller and the controllers manage the PWM to the laser.
Sorry where you doing something with the laser?
Ok. set transfer mode to buffered.
Disconnect Shapeoko from power and from USB. and wait 30s.
Reconnect everything and try again.
So each time Lightburn is closed or something is changed, the +X and +Y quit responding so I added $RST=# to the top of the Use Laser macro to see if that makes a difference but it doesn’t. I have to manually enter it each time the program opens in order to gain four-way function of the X and Y axis. Still no response from the Z axis.
I will do the disconnecting and get back to you in a few minutes.
