Hello, new to the forum sorry if I am posting in the wrong spot but I was wondering if maybe someone could help me. To start off I'm not new to building CNC machines and such. I've built allot of c02 laser, routers, printers whatever it is I've probably messed with it somehow. So, to start off I got a broken fiber laser it's an IPG brand model YLM-60-AC-ES the laser was removed from an Esko CDI spark 4260 in working order. It was broken because someone cut the fiber in order to remove it. Not a big deal I am a fiber splicer by trade I own all of the Propper equipment to fix the fiber that was an easy fix. I am working on building a laser engraver with this source. I have a galvo and a JCZ Ezcad2 control card and a copy of Lightburn. The issue I am having is seeing any signs of life out of that laser. I don't know if I have settings wrong in Lightburn or if that model does not use whatever standard communication protocol that these lasers seem to use on the DB25 port. I contacted IPG to try and get some info on that specific model of laser and they told me that that model number scheme was a custom OEM device made for Esko and in order to get the specs and pinout info I would have to contact Esko. I contacted Esko and that went about as well as you would think they couldn't seem to comprehend what I was even asking. I took the main board out of the laser to try and dig deeper in on the pinning to see if something is different and it seems strange to me that pins 1,2,3,4, and 9 are soldered together and connected to ground. And pins 10,11,12, and 13 are all connected together as well but not to ground. These connections don't seem to make much sense to me when you compare the DB25 pinout of a JCZ control board.

again, sorry if I am in the wrong place entirely with this just looking for some more ideas on what to try before I move onto a different laser source.


Thank you!
