[MSG:Check Limits]
Not tripping homing switch. Does your machine have homing switches installed? If not turn off homing at start up. If it does have homing switches make sure it is homing where the switches are located. If it is make sure laser is tripping each switch.
The limit switch is OK, I checked it. / When I am using “LaserGRBL” limit switch works fine. No issues
It really isnt, this preceeds lightburn
This is GRBL error code, meaning your machine is - at the firmware level - warning the homing cycle wasnt performed correctly.
What initiates the homing cycle is of no relevance in this case
As I see the Lighburn behave rather erratically sometimes not recognizing limit switches and later it does. Every single time I am initialing the HOMING it bumps against the rails with noise. When the “Homing” command finally somehow expire (After clicking whatever I can) it works fine Framing and cutting nicely. From my point of view (at this moment) it looks that somehow the working area is not aligned with the view we have in the laptop window. I moved the cutting head to the right/top position and tried to move it 400 mm further/ away from me. The Head again bumped with grinding noise against the far away Rail not recognizing the limit switch. When the head is far away from the “Home” corner when connection with LighBurn is initiated , the head comes to the homing position shaking with odd noise and is bumping against the rail. The same rail/ same switch easily recognized when I am using the LASERGRBL program. I think there must be some problems accumulated when the software was developed. (Same like with the GIMP not showing the correct colors in its window. I downloaded the original Portable Gimp version and now it shows correctly etc.) I am going try some basic versions of Lighburn to see if the issue persist. Every time moment the laser connects with Lighburn it starts immediately to shake. I would give up on this laser if not the fact that it cuts beautifully and without any sooth. Sooth I get every time I am using my old junky Chinese 80w CO2 regardless of the settings.
You cannot complete the Homing cycle by clicking around until it expires.
Exact Home Cycle process:
If your machine does not do the little dance at the switches without an error and banging into the frame, it did not complete the Home cycle.
You might be able to override the alarms created during Homing, but positioning is unpredictable after that. Your comments after the quoted part seem ti indicate this.
If you have Home Cycle enabled, parameter $22=1, then you have no choice but to Home the machine properly if you want predictable positioning. You might also consider using Absolute Coordinates exclusively. I do both and do not have positioning problems.
The problem is that I should have used the correct home position in Lightburn. The Atomstack home position is in the lower left corner. (blocking easy access to the working area) I was playing with the home position in the upper right corner, assuming I could change that like in my CO2. It Cuts just fine, but only with the 24W power selection. The 48W has much lower power. Barely enough to cut 100# Cover paper. Something is wrong with the switch. Something inside is blocking the light, or the switch is activating only the other set of (much weaker) diodes. In addition, when I move the rails front and back, they move with the noise and dancing moves of a shopping cart with one busted wheel.
One of the wheel’s ball bearings is gone. I requested technical support from the manufacturer. They flatly refused, telling me that I bought it from a dealer and that the dealer should provide the tech. Support?. Since I purchased it from THEIR OWN STORE on Amazon, I asked again. This time, sending a video link showing the fault and the trigger point was the answer. I sent them a link to a video showing the cutting test with the 24 and 48 setups and the rails moving problem, and I was waiting for an answer for several days. Finally I returned the machine. I liked it very much. The speed and clean Quality of the cuts with no charring, but I can not keep junk and have no essential tech support. It is costly.
Sad story! Odds are they just import from China and have no spare parts. I feel lucky I bought the Sculpfun S30 Pro. No hassle, but it does Home front-left. I just set the finish position in the back.
I received today another e-mail from Atomstack telling me again they will NOT provide technical support because I bought it from a dealer. The 'Dealer" is the Atomstack Store on Amazon. In Addition, I noticed That they are actively removing posts on their Facebook users group—three posts about people receiving their devices with one of the rails shorter. Two of the posts are gone, along with mine describing the technical problems and a video link showing the music of the rail with a wheel busted. I am SO Happy I returned their junk. Today, I received a new SNAPMAKER RAY and am starting the setup.
that sucks 
Hope your next experiences are way more smooth! keep us posted
Yesterday 2/22/23, After two weeks of the Chinese New Year and receiving a couple of e-mails where Atomstack refused to provide technical support because I bought it from a “dealer” - Their store on Amazon. Finally, I received the first advice on dealing with the Problems/ The Advice is: “SLOW THE SPEED”. WOW!!! It is going to be a cure to the busted wheel bearing and the 48W setup having less power than the 24W ?
How on earth does such a “Company” of ido… still exist? I returned their junk and purchased Snapmaker Rey.
Today, I am finishing set up and testing my new Snapmaker Rey. The Details of this machine are impressive. The only thing I do not like is their LUBAN software. Luckily, the Lighburn came to the rescue, and I did not have to experience a Greek tragedy dealing with LUBAN. The first test comes out nicely, and I will test some thicker materials to see how it goes.
