** open marlin.ino found in the 'marlin' directory click the verify/compile button click the upload button if all goes well the firmware is uploading and you'll see the led on your arduino flashing wildly.. Laser/spindle configuration this document is based on marlin 1.1.2 note: because of the way marlin currently (1.1.9) implements m3 - m5 , for best results we recommend ( #11576 ) using a fan pwm pin and the m106 command instead of m3 - m5 .. Firmware marlin laser setting. i was able to modulate the laser as i thought. work! firmware to say to heat the hotend and in place of the resistance is the 12v power of the laser driver. to ttl cable to connect the modulation pin 44 after remapped as by leo69 guide..
Most of the marlin and other firmware checks to see a minimum temperature and then there is a profile for keeping the cooling correct. we mostly use the fan control for the laser because it has pwm functions in most of the printer firmware out there already installed.. I am stuck. i thought i could just use marlin firmware to control the custom 3d printed laser cutter. i had seen some fellas use one of those chinese laser cutters and converted it with ramps 1.4..
