Power Output inconsistent on CO2 tube.
Posted: Fri May 06, 2016 6:53 pm
Hello,
I am having some serious issues with my laser cutter.
I have a 500mmx700mm laser machine which I modified to and I took it from 50 watts to a 150 RECI S8, p18 laser power supply, AWC 708 LITE DSP, 5300 water cooler, larger mirrors and lens, new laser heard and some other upgrades.
The latest problem is that after replacing the DSP controller ( I previously had a RD6442G that I could not get more than 30% power out of the system when measured with a CO2 laser probe AND I was getting inconsistent power output, It would show on the sample cuts and in the visual inspection to the laser tube, pinkish light would not stay on when cutting a long straight line but it would flicker) I would get ALMOST all power out of the system (%80 when measured with laser probe) but I still get that flickering effect that ruins anything I want to cut with my machine. lense and mirrors are almost perfectly aligned (four corners and center also). IMPORTANT DETAIL TO OBSERVE: when I bypass the controller using a push button I get the %100 output which is super powerful because I pierced a piece of 3/64" or 1.2 mm stainless steel sheet metal.
So, the questions are:
Why I have the flickering and inconsistent power output when using the controller and not the bypassing it.
Why I dont get all the power out of the system. ( I know that it is not good at all to use %100 of the output, but it should deliver it if needed)
I will appreciate any help. I've been working on this upgrade for at least 8 month now and I spent more money that I should have but i really want to get this laser system running as it should.
Please check attached pictures
Thanks in advance.
