Hey All, I have a question about the high voltage wire and the flyback. I am enlarging the K40s cutting area within the k40s eclosure, so I removed the electronics and its being put in its own enclosure. My problem is two things. 1). The high voltage wire has some chaffing where it comes out of th…

The High Voltage connection is potted into the HVT. I would not recommend removing it. What supply do you have, show a picture of the problem area? I thought the standard supply cover does not encapsulate the HV output?? Add a grommet or some plastic grommet material to the edge it is chafing aga…

Hi Don, Thanks for the reply. Adding to the pigtail was my original intention, but if It was feasible to remove it from the flyback and start new, that’s was what I’d prefer. The housing does cover it, but when opening and closing the electronics lid on the k40 enclosure, it moves the wire around c…

I would put this on the edge of the LPS: https://amzn.to/2Fwn7kq … and then add the connector to the HV wire making a pigtail as far away from the enclosure as is practical. … if you make a splice also do it as far away from the enclosure as you can. This voltage can jump up to 2". If you splice…

Hey Don, Do you think the length of the high voltage wire will effect the the laser output? Regards Bill

Not within reason … like the length of the cabinet.? The big problem with long HV wire is the e-noise & static build up that it may cause. Route it as far away from the electronics as possible.

Hi Don, Thanks again for your reply. I’m using the stock electronics, and both steppers will be on the left side. The laser tube’s + side is on the right, so it made sense to put the electronics housing to the left side of the laser’s enclosure to keep the stepper wires as short as possible and to …

Hey All, I started tearing down the laser and repopulating the electronics in a new electronics enclosure. There is no way to splice the high voltage wire to where it’s not going to be anywhere near the metal enclosure. It’s just too short from the factory. Either I have to splice it, and it will …

I think either will work as long as you make the splices correctly including the tube connection. If you have a long enough piece, I would elect to use the single piece and make the connection at the tube. Is the LPS staying in the laser cabinet or the electronics cabinet?

Hi Don, Yes, all the original electronics are to be used and enclose in a separate box. Here are some pictures. I need to shorten the wires and connect them to the PSU. I placed the top on to give you an idea of what it will look like. I am amazed that the color the box comes in matches the K40 enc…

Is your HV cable exiting the electronics box and then entering the box with the laser? I would be nervous about that being outside where a human can access it. You know that that cable runs 20,000v right? If it runs outside I would fin a way to enclose it … I strongly urge you to add interlocks …
