Hi all
Weird one… have a 50W China laser with a Ruida 644.
HV PSU failed just before Xmas and replaced with a Cloudray HY-T50 PSU. All was working fine.
Now, all of a sudden, whenever I do a cut/line, the power isn’t adjustable. Irrespective of whether I set to 0.1% (which shouldn’t even fire) or 80%, the power output is the same.
Has anyone come across this before? Not sure where to even start with this one… Thanks.
