My new Atezr 35w+, after running a few material tests and calibration tests I began a project. About 45 minutes into the burn the laser quit firing while the head continued on, following the GRBL program. I tuned the machine off to research the issue. The next morning I put a volt meter to the power supply = AOK; cleaned the laser head according to Atezr video; checked Machine Settings: S30 = 1000, S31 = 0, S32 = True/1. Sent email 2 weeks ago (just b4 the Spring Festival) to Atezr yet no response.
I would verify a couple things
Remember you can rerun the project at 1% to save materials
a) does it stop always at the same zone on the project
b) is it localized in a particular zone in the bed?
c) you are using GRBL controller and not GRBL LPC or M3 correct?
a) I ran it twice, the laser did not fire again after it initially stopped.
b) It is not localized. I failed to mention I checked to assure the cut area was under the performance parameters of 430x430mm by setting the gut area 425x425mm. I then turned off Arrange and tuned on Arrange Long and centered the project. The laser is set to Absolute Coords.
would be on the cable that connects to the laser head itself
You want to verify if the laser is fail to trigger OR if the motherboard/Wiring is failing to deliver the trigger signal
might be a bit technical unsure if manual has a pinout of the wiring on laser head
Its discoverable by opening module and checking the pcb but honestly, this is outside the confort zone of advise to give, especially when is under warranty and you are in contact with the manufacturer.
I would suggest to be patient and wait for them to reach out
I will spend some time this afternoon, although it will be working in the dark, to verify that the wiring connectors and wiring is intact and feeding power as needed.
The Chinese execution of service is non-existent and not just with this equipment in general. I’ve spent the better part of the last 60 + years of my life (now 77) in the service industry. Lightburn is at the panicle as a company and you folks are suburb in forum support. I can only thank you and applaud your efforts. Some day someone will initiate a company that will distribute and service a few of these popular machines and make a bundle!
you could inspect the output at the motherboard connectors, those should be labeled
If the PWM and 24v(if its 24v) exit motherboard you should then be able to use multimeter to identify which connector is which on the other end of wiring
Also test continuity to guarantee your cables are not broken
IF all is set, this means the issue is at laser head itself
Lol, above and beyond the call. I completely missed the Atezr community site. Their FB user page is useless as they block issue posts. Your help is deeply appreciated and highly informative.
Gil, I was all ready to undertake the “follow at my peril” road when, I decided to take one more look at the laser optics to see if I had cleaned them properly. The project I was cutting I had spray painted. It was a valentine project for my granddaughter. Long story short, it was cutting 12 ea of a 5 piece set. I took the air assist off and looked at the optic one more time. Alas, looked good to my novice eye but decided to do a more thorough cleaning on both sides of the front optic. I used optical spray and a silk cleaning cloth. Gad I couldn’t believe how much “stuff” came off of the lens…on the inside! Reassembled and it and it worked fine. Lessons learned. I’ve wasted your time and apologize. I’m thinking that spray paint does create a lot more issues as my naiveite didn’t realize. Again, I deeply appreciate your help as it opened some doors to help me think details matter. What a learning this has been.
I will make a reference document and post it 1st of next week. I can’t express enough the frustration with the sloppy QC from the factory and then my miss cue’s, but my how good the learning through hard knocks…even at my age. When I opened the laser unit I was amazed at the residue that I did not remove the 1st time around. This time it sparkled. I did run a Material Test for both cut and engrave then ran a small graphic through a cycle with the best settings. My settings were close to the material settings in the Atezr Forum you highlighted. Viola! I’m amazed at the great performance of this machine.
