Doesn't sound too dissimilar to what happend to me a few weeks ago ... everything was okay for a few seconds and the laser stops ... but keeps moving like it is still working (just no laser) ... small tests worked as did anything on SUPER low power ... turned out to be a faulty power supply which th...

Re: Laser stops firing during cut

UPDATE ....

Just spoken to one of the engineers at HPC and he's of the opinion that it could be a power supply issue ... and is going to confer with one of the other engineers to see if they agree, then I guess it'll be a case of buying a replacement supply and giving it a go.

Re: Laser Stops....

Re: Laser Stops....

You will need a multimeter. .... and someone who knows how to use one, lol. Fingers crossed my mate will be around later to finish off some electrical work that he's doing ... I'll get him to check that as an option for me. Being a switch (and I am aware of the risk in doing so, as the laser would ...

Laser Stops....

Hopefully someone can assist... I have the LS3020 machine and last night, for seemingly no reason the laser stopped working mid cut, though the machine continued around the shape, as if nothing had happened. I checked over everything that I could think of ... plenty of water, it's circulating and th...
