I purchased this machine used and partially apart. They had installed the laser power supply and the 100 watt tube. the interface panel on the top of the cabinet was installed but the controller was just in the box. I never saw it work. So I am very new t o all this and am learning fast. indicator led lights, #3 lights a couple times when first starting up, once the head stops 14 comes on and flashes, #15 comes on when powered up and stays on. I go to the diagnosis panel and I cant access anything there
the only thing that I can get to light up is the read button and if I hit enter, no changes
Your controller usually has the legend to the leds, doesnât yours?
If 13 is lit, you have an internal hardware error. 15 (5V) is usually lit and run flashes. Link also flashes if youâre using Ethernet and moving data.
What does your machine console indicate when it finishes booting? Can you post a photo?
Please: go back to the top of this whole discussion and do what I suggest, in the order I suggested it, and report back.
Pictures will be helpful.
EEEEK⌠playing around and when I saw that a new version of lightburn was available I clicked update. It did. So I shut it all down and restarted software and machine. Both limit switches are working correctly. travel distance was correct on the X travel, Y still wanted to come too far forward. I watched the distance travelled on X. It read 750mm on the machine however a ruler said it should have been more like 950. So I went into vendor settings and changed the step size and hit write. WRONG THING TO DO. It wrote all the stuff I had changed before I updated versions and now things are messed up. Question now is how do I get back to a clean version where the vendor settings are original?
Hit the Reload from backup button and pick a file with a suitable timestamp:
OK, I will be going through these.
Protip: Change one thing at a time.
Then you can verify that change did what you expect.
is there any resource the explains what each item is in the machine settings and vendor settings?
Nary a one.
The manual for whatever controller you have is its âbestâ reference, but IME generally does not match the actual controller menu structure and does not give any explanation of the âwhyâ behind a brief description.
The hive mind here knows many things, most of which bear some resemblance to the truth, but to a large extent itâs all hearsay evidence. 
OK, I am addressing one problem at a time now. I am trying to get it to home. in the vendor settings I cannot get the limit trigger to go true. it is false and does not let me change it. ?>>>?
Hi @Jdrax
Not to butt in, but I have done many a controller swap to ruida and I can tell you that as long as both motors are working and your limit switches are working to (whilst the machine is trying to home, even if in the wrong direction, you can test them easily enough) then you do not need to fiddle with wiring.
See the below documentation page.
I highlight this partâŚ
There are only 4 possible combinations of Limiter Polarity and Direction Polarity for each axis. Without access to your machine, we canât tell you the correct combination, but change those settings for the X axis until it moves properly and recognizes the homing switch when you power up the machine. Once the X axis is correct, do the same for the Y axis.
Usually itâll be the X axis youâre having issues with. Often how I resolve this is to make a table of the 4 options and all the possible combinations, then I work through them until I have tried them all (or found the right one). Be ready to reset the controller and also use the ESC key to stop the moving parts. With the power off you can carefully pull the gantry and head back to a reasonable start position for the homing process.
I hope that helps!
As I said above:
Then it should move properly from the console and in response to the LightBurn jog buttons.
If it doesnât, take screenshots of the current axis settings so we can look over your shoulder.
Show us what youâre doing.

Hi Guys (and gals)
Thanks for patience and for your help so far. I finally got time to spend getting my head wrapped around these concepts and watching the machine to understand what was happening . I think I have my movement and distance problems solved. I have the settings close enough to be able to wait now until I can actually cut something and then finally tuning to get it exact. Next step, get something set up for protection with water flow. I have a CW-5200 Chiller. is there any circuitry built in to tell the laser controller if it is running or do I have to purchase a flow meter / switch or such
One more question, regarding the lift cylinders for the cover. They are 11" but approximately what weight should they be rated at for a rabbit 600 x 900 bed machine. I tried 40 lbs and they are way to light duty
My laser had a pressure switch that grounded the CN5-4 or WP1. Looked like this.
I used itâs wiring from the connector to Ruida, since it was in place and the switch was near where the coolant entered.
With a chiller, it monitors not only coolant flow but temperature. Ground H1 and wire H3 to CN5-4 or WP1 on the Ruida or vice versa.
This is mine, with the chiller connections circled in red.
Make sense?
Clueless about the hydraulic lifts, mine failed a couple years ago, I have a piece of acrylic laying around that was notched and use it to hold it open 
As @jkwilborn points out, all you must do is wire the chiller to the controllerâs WP1 input and youâre good to go.
My LightObject Q600 chiller has slightly different plug wiring and I added a matching aviation connector to the laser cabinet:
The machine had an internal flow sensor, so I put the chillerâs alarm wiring in series with it so they both have veto power.
Thanks once again
can someone tell me what plug I should look for on the CW 5200 chiller
I think this is the 16mm plug on the chiller⌠Others can confirm. It was so long ago I purchased one, that Amazon canât find it in my orders.
There isnât much choice as thereâs only one.

Wow, Thanks to you folks I am just about ready to see if the laser will fire. Then I can start aligning the beam and mirrors. I have the water protection cable wired from the chiller to the controller. One more small detail. The little light that is mounted down on the laser head that is suppose to shine onto your workpiece showing where it will cut⌠the two wires are connected up to the laser head light⌠where do the other two go that powers it?
