DIY clone for Jtech Laser Add-On

Post by hesslerk » Fri Oct 20, 2017 1:33 pm

Hey,

I was interested in the jtech photonics laser add-on but can't cough up the $400+ for the kit. Anyone have experience with buying the laser diode/building their own driver board? I am pretty handy with circuit design/builds so that wouldn't be a problem.

There are a couple of links and notes at: https://www.shapeoko.com/wiki/index.php/Laser_Cutter

My understanding is that most of the expense is in the diode --- if you're willing to accept less power pull one out of a DVD writer?

Two things you get with J-Tech, the best support bar none and a power supply you cannot kill.

I purchased an original 1.8 watt laser which had problems and he replaced it no questions asked. I have also done some stupid things to the power supply which would have killed any other one but his kept going.

Yes there are cheaper alternatives but what is your time worth?
