I have an arduino with a cnc v3 shield moving the head around. I put an led on the spindle speed output and can turn it off and on, and dim it. is there a way to use this to turn the laser off and on via mosfet etc ?by baloo - Laser Cutter Working Group
Thanks Viktorby baloo - Laser Cutter Working Group
see attachments that is all I can see in photo 1 the red black green an blue are the 12v in, the blue and green go starte to the fan. in photo 2 the resd and yellow go start to the diodeby baloo - Laser Cutter Working Group
Thanks Viktor I have been trying to contact the vendor for a month now, they do not answer me, so I'm flying blind here. I'm not any good at electronice, (i'm a retiered shipwright ) The only info I have is Working Voltage DC 12V Laser Module Power supply:5.5W Wave Length:450nm my option is to use a large Mosfet to handle the current and heat ??by baloo - Laser Cutter Working Group
.". first -- the "5.5W" is the driving "power" of the diode, not the optical output energy! " I took the fan of the top of the Laser to see what voltage is , its 12v, it get its power from the same terminals as the laser board. so at 12v 5.5w i should only be drawing P/ V = A .. 5.5w / 12v = 0.458 amps ?by baloo - Laser Cutter Working Group
A month ago I got a cheap china laser engraver see It had no instruction on how to build it ,but I had built one before (300mw laser), the problem is that the control board get very hot and the solder melts. so I believe its the wrong control board for the 5.5w laser. I would like to use an Ardunio uno and cnc v3.0 shield, but need to drive the 5.5w laser form it. Can anyone help on how to do iby baloo - Laser Cutter Working Group
