I recently purchase an Ebay 5065 3W Laser Engraver; here: https://www.ebay.com/itm/50-65cm-3000MW-CNC-Laser-Engraving-Machine-2Axis-DC-12V-DIY-Engraver-Desktop/323612235970?epid=7027288534&hash=item4b58cad8c2:g:CtQAAOSwNepcUo7a:rk:1:pf:1&frcectupt=true And also purchased a license copy of LightBurn. I added successfully the Arduino Nano - but for some strong reason the laser head keeps crashing into the corner frame. Does anyone have this same laser engraver and won’t mind sharing your settings? Thank you!!
