I do not mean it like that. I thought if you could upload an image that you have prepared in PEP6 so I'll see how you've edited before taking out the gcoden for the laser engraving

Hi.

Now I have changed the motion board to a UC300 ethernet and test drive with a nubm44 laser powered by a blackBuck 8M laser driver. The driver gets 6vdc and the x-y-z acceleration is 1000. Engeaving speed 2000. Now I do not have so much trouble with stripes anymore but it burns way too dark.

With the 6W nubm44, I laser engrave photos at 5080mm/min on Birch Ply, or Poplar. At a 2000mm/min it will burn too dark. It looks like your testing on MDF. It will burn easier/darker than natural wood. You may need to back off the max setting or driver max amps (if adjustable) and use a B&W dithered image instead of trying to laser engrave grayscale.

I recommend you use a 3" (76.2mm) focal height. Focusing info can be found on Page 22 in our Laser Setup Instructions.

Updated the uc300 card and reinstalled mach3. I made my own test picture with a white box at the end to see if the dac has lost stepps. Feed 5000, acc 750 and can engrave at 6500 mm / min max. 8.5vdc / 2.4A gets the laser. I'll try more this week for the optimal settings.

Have you tried laser engraving any photos again?
