I installed this laser onto my 3D printer https://www.ebay.com/itm/Focusable-Analog-TTL-5-5W-5500mW-450nm-blue-laser-module-Engrave-cutter-/192488753227?hash=item2cd139484b#rwid
I am running it on this board with Marlin firmware https://www.newegg.com/Product/Product.aspx?Item=9SIAEF87NR2365&ignorebbr=1&nm_mc=KNC-GoogleMKP-PC&cm_mmc=KNC-GoogleMKP-PC--pla--Accessories±+Printers%2FScanners%2FFaxes-_-9SIAEF87NR2365&gclid=Cj0KCQjwqPDaBRC6ARIsACAf4hD-fIKAds3zrPjFdzhwgdtZWqaqtBREeChcL3V4HhpMIMDT-q9YUjcaAk2KEALw_wcB&gclsrc=aw.ds
Using LaserWeb 4 I can cut materials just fine, however I can’t raster an image. At the end of each move the G code generates an M106 S0 which turns off the laser and doesn’t turn the laser back on until part way into the next move. It misses the first part of the next line’s engraving. I’ll attach a picture of the gcode below. The laser only works when the driver board is in the TTL position. Do I need to do something to make it work in analog? The output power of the laser does modulate from 0-255 as it’s supposed to. I am new and don’t understand most of this. Any help is appreciated.
