Do you have the power to run it? If it came this way, it’s probably ok, but it would be a drag to find out you don’t have enough power (wattage) to run it… If I read your post correctly you have a 3.8 watt laser, input power, so it’s drawing about 320 ma.

If you can follow them and confirm them, then we can start looking at the controller followed by lightburn… dubious it’s lightburn. If you want to try while you’re waiting for a reply from j-tech…Īs I said there is only 3 connections. We can probably figure this out, it’s not rocket science. Ensure we have the proper hardware configuration before any worry about the software side. It’s a two pronged fork, half hardware the other software. I can see the PWM output of your board, so you should only need to ensure you have power. J-tech should be able to tell you what wires go where. Lot’s of people have these issues, we’ll get you up if you can be patient enough for us A red led could be an error or normal operation. If I remember that’s it saying it has power?įirst shot should be what indicators do you have, and for us, we need to know what they are.

If you have varying descriptions, you may have to chase the wiring down to the part to ensure what’s what. Just check out what supposed to be and double check that it is. It does sound like it should be an easy fix. I’ve broken more stuff getting frustrated and doing something I knew better… We are here to help and usually what I tell people first off is ‘sit down with a cup of coffee and relax’ Normally I don’t post like that, but… There was no intent to ‘excite’ you, just a pun on the mess.
