Echo7394 / LaserFish

Marlin comes preconfigured to not be very friendly with laser engravers/cutters. This is due to the frequency of it's PWM ofen being too low. Once the firmware is reconfigured to work with lasers, it often does not work with 3d printers any longer. This firmware solves that. So this is just custom version of Marlin configured specifically for 3D printers to be able to laser engrave/cut while still maintaining the ability to print as you normally would!

[Feature request] Audio alert when finished #2

Open r3dsk1n opened 2 years ago

r3dsk1n commented 2 years ago

I like your build, for some reason im getting much better prints with this firmware. I've complied my own but my ender3 with the silent board upgrade works better with this one. But anyways is there a way to trigger some kind of alert when the print is done?

I also upgraded to a 20w laser, but I used the 24v pwm signal and fed it into an optocoupler with a 7805 and forced it into saturation. I got the idea from another guy somewhere. But I just used a run of the mill 4 pin optocoupler from a wall wart And pumped 12v into the voltage regulator and also the laser... but yeah for some reason all of my 3d prints have come our beautiful with this firmware compared to mine and a bunch of others.

I've noticed a major improvement with prints as well as a reduction in stepper motor heat. It's due I believe to the higher frequency PWM signal. As for an audible beep you can add some gcode such as:

M300 S440 P200 M300 S660 P250 M300 S880 P300

To the "End Gcode" of your slicer to have a series of audible beeps at the end of your print.
