I just joined the forum and this is my first post. I have a JPT 100w fiber laser with the red pointer or guide laser. Up until about two weeks ago the red laser was working fine and then nothing. I was on vacation when it happened, so I'm not exactly sure what went down. The guy that was running it said that it just stopped working. I can still mark just fine, it's just annoying/time consuming to set up now because the lack of a quick alignment. I already went through the software (Prolase 7) and couldn't find anything there that would cause this. I may have missed something though. From what I can tell, the red laser is inside the main laser because it runs through the galvo mirrors to create the preview. Again, I could be wrong. If it helps, I am using a JPT YDFLP-100-LP1+-L1-R laser with a Sino Galvo SG7110 scan head. If anyone has any advice or ideas it would be greatly appreciated.
