Gravograph Is400 TM conversion... we sold our Gravograph on Ebay, but UPS damaged and they buyer refused. We got it back and the brain (separate box control) is fried. We have an extra cohesion 3d and Arduino board but are novists at best when converting. We already have two lasers and just want to use for metal engraving machine and cutting. Any advice?
