Laser quit burning
« on: June 13, 2021, 08:34:05 AM »
Howdy Folks!

So my no-name Chinese laser quit burning in the middle of a job - still lights up just not enough juice to burn.  It is a 3W laser = so I am guessing it is toast.  Thinking of replacing with a 5W - but not sure if the cnc controls would work right.  Any thoughts on what to do???

To add a little more detail,  the cable to the motherboard is a 2 pin plug that goes to a control box, them 4 wires to the laser head.  Which is the dilemma in getting a replacement.

Does the control board have a 3-pin laser output?

The older 2-pin does not have a TTL signal which is required for most laser modules, so either you can manually wire it to D11 on the Nano or get a replacement controller as well as a new laser module. The controllers are cheap and then you would have spare stepper drivers.

Thanks Zax, you are always a big help. Appreciate the assist.  It is a 2 pin - I think I'm going to step up to a bigger laser.
