I turned on my Bescutter laser this morning as I normally do. The rail that holds the laser in place didn’t go to it’s normal origin spot but instead slammed into the left wall of the machine and tried to move past it, which it couldn’t.
I quickly turned the machine off and turned it back on. It wanted to do the same thing. I moved the rail system all the way to the right and then turned the machine on. This time, it went to an origin spot that is not normal (it goes too far left).
I tried to engrave, but now the machine and the workspace in lightburn are not lining up not. It’s as if the machine thinks it is in one spot but the lightburn workspace is in another.
Also, when it comes to the physical up, down, left, and right buttons on the machine, the left button suddenly does not work. It’s as if my laser had a stroke in the middle of the night.
So two issues, and I think they are related: the laser turned on this morning and decided to change it’s origin point and now tried to engrave outside of it’s workspace, and the physical left button on the machine is not working.
The root cause is most likely a failure in the proximity sensor from actuating. In this case, sounds like for the X-axis. Either the sensor itself has malfunctioned or something is preventing the actuation.
Examine the machine for why the X-axis proximity sensor is not actuating. You should be able to look at Ruida diagnostics screen to see whether or not each sensor is currently actuated.
this does seem to be a part (or whole) of the problem. I went into Function+ > Diagnosis+, and in that screen it shows the XLimit- as having been tripped, as it’s got a red box next to it.
So I have a sensor issue? Is there a way to fix? I guess I’m also not understanding how this sensor issue would cause my workspace to now be misaligned. I understand that when my rail slammed into the left side of the machine and kept trying to “move through it” it misaligned the workspace, but how do I fix that?
This is likely a downstream effect of an improperly homed machine. Without the proximity sensor working for homing, the laser is not aware of it’s actual position.
If the hypothesis above is correct, then this should self correct once you address the issue with the sensor.
First, determine whether the sensor is not functioning or if something is preventing proper actuation mechanically.
Is the red box in diagnostics turned on perpetually? Meaning no matter the position of the laser head? If so, physically examine the sensor to see if something is actuating it. It’s possible that something ferrous or magnetic lodged itself onto the sensor. I’m assuming you have inductive sensors so correct me if that’s not the case.
