I might have bit off more than I can chew with this project. I am new to the laser community and have recently purchased a CAM five 100w laser that was working when I bought it. I did not want to use their software so decided to upgrade to a Ruida 6445s. I found a post that got me pretty close to completion.
After hours and hours of trying to get the laser to fire I decided to go ahead and upgrade the LPS (cloudray m100) so I could get the potentiometer out of the equation and know what wires go where. Here is where I currently sit and need help. I believe that my laser 1 output on the ruida is not working so will be working on getting that exchanged. I get no voltage on L-on1 when the laser is not in use. I currently have the LSP on laser 2. The laser will not fire at all when connected to the LAN2 port but will fire when connected to the LPWM2 port. When i put the ground from the WP into CN6 the laser will not fire. Here are the current connections I have.
WP2 → Goes to water sensor
LPWM2 → IN
L-On2 → L
Gnd →G
The ground for the water sensor and P from the LPS are going to a gnd on CN1
I currently have the white wire coming off the back of the M100 connected directly to the negative on the glass tube.
The issue that I am now having is that the laser will fire but it will continue to run the entire time a file is going. It will not shut off to move to the next letter or shape. It will burn the acrylic the entire time. When you click return to origin the laser will turn on and fire until it reaches origin. When you turn the key switch on to initiate the homing sequence it will fire after homing to the origin. I am unsure if this is a software issue or if this is a wiring issue. The current way it is working is that a key switch will turn the ruida on and there is a push button that once pressed gives the laser the ability to fire. I will attach some photos of my current set up. Please let me know what my next steps should be.
Something is wrong with the L-ON signal to the L terminal
The power supply is defective
As a test:
Unplug the connector from the power supply to get it out of the picture.
If the L-ON signal at the controller remains low (near 0 V, relative to GND) all the time, then the controller isn’t setting that signal high (near 5 V), which means the controller is defective.
Plug the connector into the power supply.
If the L-ON signal is now low, the power supply is pulling it down when it should not, which means the power supply is defective
I was able to do a bunch of testing this afternoon and this is what I have found. The laser one (CN5) on my controller is bad. I get no voltage going to L-On1 when nothing is plugged into it. When testing L-On2 with the power supply not connected I am at 4.1v. When I plug the power supply back into CN6 I do not get any voltage on L-On2. I had the G from the power supply connected with the ground to my water sensor connected to the GND on CN1 (had it on CN! because it would kill the voltage on L-On2 when connected to CN6). When I remove the CN1 connector I get a voltage reading of 6.2v going to L-On2. The machine runs as intended but it has to be on laser 2. When connecting the grounds from the power supply and water sensor I get no voltage on L-On2. I currently have G from the power supply and the ground for the water sensor connected together but not plugged into the controller and it seems to be working. When I connect the grounds back to the controller I get the issue of the laser always staying on.
Both the controller and power supply are brand new from amazon.
