Laserweb

Laserweb needs to be configured to make it work:

Choose Grbl as board

Set the Laser on as M4, Laser off as M3 or M5

Set the laser power as i.e. 1000 or 2048 etc (Same as $30 setting of Gerbil. You can look up the settings via a gcode sender. Send $$ via the command line and Gerbil shows you the settings).

Will look up the exact locations of the Laserweb settings.

Thanks Paul.

Many thanks Paul

You're welcome John. LightBurn is also a nice laser cutting and raster program that you might want to try out.

Somehow Laserweb on the raspberry pi is not working with Gerbil ...

 Any idea what I can try?

Can you share a laser test fire macro that would work with Laserweb?

None of the programs (laserweb, lightburn) test fire works, and since dropping the gerbil in, my hardware test fire button no longer works.

I still get the rapid 3 pulse fire when I connect my gerbil to the laptop, and it cuts when it should as it executes the gcode, so I know that the programs are configured correctly. However something is out of alignment and I need a testfire option in order to do a mirror alignment.

Thanks!

If you install cncjs you can do test fires from within the software/pc. Alternative you can wire the LO port (first screw terminal on the first 4 pin connector from the right) to a push button that grounds the connection. That fires the laser.

Could you still add the 3 pin switch between PWM and rheostat control of the current and have the button work?

I think this is more of a laserweb issue. There should be an option for the test fire button to send a GRBL command to turn the laser on then off.
