On mine, I press Z/U → Laser Set+, here you can change the pulse to be continuous or for a specific time period. Set this to continuous. It will lase as long as you hold the pulse button down.
Back out of that menu and press the Max button, here you can set percentage power. Set it to whatever you’re checking.
I set mine to 50% when working on it.
Make sense?
gotcha. will report results tomorrow
OK, test results using the pulse on the console
tests at 10%… .5 v
25%. 1.25 v
50%. 2.5 v
75%. 3.76v
99%. 5.95 v
so is there a setting that can be wrong or is the ruida controller not working
That looks high, but an exact +5V supply seems to be aspirational for those controllers. I’d say it’s close enough, particularly as all the fractional values come out about right with the correct ratios.
that was a typo… should be 4.95
So… now what does that \tell me about which unit is the problem
or is there some setting I am missing yet
could I switch over and use the connections for “laser 2”
There is no legitimate reason to drive things at their maximum when setting the machine up. You can tell if it’s working or not keeping power down to 50% or below.
Controller seems to be working, I’d start thinking about an lps/tube issue.
I am confused. What are these numbers saying? How can you tell if the controller is good? The tube is new.
You’re getting correct voltage out of the Ruida to control the lps properly. Assuming water protect is strapped to ground.
Correct voltages to the lps, such as 50% power producing 2.5V, as you noted earlier that the L terminal went low. These are the only control signals the lps needs to lase. If it’s not lasing when told to, the next step is a possible failure of the lps, since we can’t know the tube works if the lps is failing.
If you pulse using the little test button at the tube power supply, is the burn and mA reading greater than what you are seeing now?
Hello again, back at it. I ran tests and made a chart. The readings for pulse were gotten by setting the % of power on the control console and using the pulse button on the console’
The computer readings were taken while changing the settings on the computer and cutting a small square. The computer settings dont seem to change power output of the laser at all. I have to be missing something .
What lets the computer control the ruida laser output?
Update…….Research and Read………I learned that in line mode if you have the speed set too slow it will limit the power output no matter what you set it at. After a bit of playing I have I now have the ability to get higher power output, I still am not getting enough power to cut 3/16” mdf. This is supposedly a 100 watt laser. 80% power, 4 passes, 14 mm/sec"…… only about half way through with air assist on. I think I have to study more about settings
What did you do to get to where you are? The idea here is to educate others so they can, in turn, help others. So, it’s nice to hear what you found.
The start speed determines where the machine goes from minimum power. If your start speed is 20mm/s and you’re going 15mm/s, you will always get minimum power. I came up with this, I believe it’s correct. Red is laser power.
On my 100w omtech I cut 1/2" mdf all the time at a speed of 2.5 mm/s and 95% power. This results in a 1 pass cut. But slow down when cutting thicker material. Oh I cut 1/4 and 3/8 mdf at a speed of 4 and 95% I could adjust the speed for 1/4 to be higher though.
make sure you have a good supply of air. I’ve got 140gallons of air at 100psi. My compressor runs every other hour when working with the laser. I use about 25psi through the nozzle. It’s important to have enough air at a high enough pressure that it puts out the fire your creating.
