OK let me start by this
Windows 7
New 60watt tube(1 moth old)
New conrroller
New powwrsupply
Here is the issue, it stared about 2 months ago in lightburn, I’d have a setting ready to go for the cut file, no matter what color I use, power seems to be at 50%, if I use that same file and setting in Rd works, the laser fires much brighter. So basically is there a setting in lightburn that’s restricting the power sent to the laser? Remember it’s only doing it in lightburn.
Maybe…
I don’t understand that, can you elaborate a bit?
A picture of your settings in LightBurn for your layers is also interesting. Have you fitted an ammeter to the laser machine?, if so, what does the 50% correspond to in mA? and lastly, what is your minimum % in LightBurn compared to your max.
I’ve been in this industry for the past 11 years and this is the first time this has ever happened, no I don’t have an ammeter connected. I have a 60w co2 gantry style machine. Only when I use lightburn I can put the settings at 100 power and 20 speed, and the laser itself fires very lightly. If I switch over to Rd works, same settings, the laser beam itself is as bright as it can be… Note this is a brand new tube and believe me, I don’t understand it either.
Thanks for the help
If you do it often (without your HV power supply being turned down to the allowable max output for your new 60Watt tube) it will not survive very long.
My 60Watt tube shows at 50% LightBurn power setting, approx. 13mA, at 65% my max 16mA is reached. This is the value the supplier recommends for my tube for long-term operation.
But that’s just my humble opinion.
I get it, but the problem is, lightburn is not allowing the laser to shoot more than maybe 30 power, as for Rd works is allowing all power… I’ll upload pics In a few
What kind of controller do you have?, could it be that there is a value that doesn’t fit correctly?
It’s a rudia controller, and it just started happening last month
Ok, if you have used the machine with this setup before without problems, then it is probably not a wrong value in the Ruida controller.
The only power limitation I have involuntarily experienced was when I had a minimum power setting below 10.
“”“Ruida controllers have a “Start Speed” setting that is usually set to 10mm/s as the default. At or below the Start Speed the controller defaults to the MIN power setting. “””"
If you have a voltmeter you can just measure the pwm output of the Ruida to see if the power setting is getting there…
@ednisley probably right about the start speed. At or below the start speed set in the Ruida it will only produce minimum power. Mine was set to 20, so you probably wouldn’t even get 50% power…
It’s more than likely set to something like 15mm/s so the increase of power might not reach anything over 50% depending on the maximum setting.
A quick test for cutting … set both maximum and minimum to the same value … 
Well, looks like you guys were correct, I set the min power to 60 and max power to 60 and boom it worked, appreciate the knowledge from everyone
