Hello, I have recently had a problem with the autofocus of my Atezr L2 24w.
When I use the “Autofocus” macro ([ESP500]), no particular problem on 3mm plywood but when it is necessary to do it on 6mm, the laser head continues to descend even if the micro switch is in contact with the board and it crushes it.
As the problem is new (I had no problems 10 days ago, I thought it came from lightburn and I extended my license to be able to benefit from the updates, but that did nothing . So I’m running version 1.7.00.
I haven’t made any changes in lightburn or on my machine recently, so I don’t understand the problem…
I am at your disposal for further information, thank you to those who are willing to help me
you might have to manually adjust the laser head to a different point on the carriage due to travel distances, I have the 48 watt Ihier model with the same z run head
Hello, thank you for the suggestion
I tried different positions on the support (very high or very low) but nothing worked with the 6mm. The laser head continues to press on it and I hear force. When I test with 3mm, however, it works normally.
strange as the z carriage has 2 limit switches 1 at top and bottom and the focus switch that stops its movement when focusing is on the bottom of the
off set piece with the crosshair.
Indeed, I cleaned and tried this switch at different heights (by pressing it directly) and the head goes up each time, except when it approaches this thickness of 6mm. I also checked the visible wires, no damage (I thought it could be a false contact with a certain position of the wire).
I still can’t figure out if it’s a “physical” problem or a problem with my software settings…
does your atezr make a beep anytime the limits are hit (my ikier does)
I was doing a cheap piece of pine lumber for a test and there was a divot in the grain that allowed the button on the sensor to not get depressed but the frame around it did make contact
Sorry for the response time.
No, it doesn’t emit a beep.
I tried several things, including disassembling, cleaning and reassembling the sliding carriage part, thinking that perhaps it was a lack of parallelism (the screws on the bottom regularly loosen on their own). After reassembling it following another post, the focus was re-done normally regardless of the thickness of the material. I was going to come here to say that it was fixed but the problem started again on 3mm.
Currently the problem occurs randomly and when the head goes down or up it squeaks a little, I think my parallelism is not perfect.
So I don’t know if I have the correct diagnosis of the problem, but it still exists.
If I find the time to dismantle it again and adjust the alignment perfectly, I will keep you informed of the result.
Thank you for your help!
