Upgraded AtomStack A20 pro to use the Atomstack MR 20 fiber laser. Lightburn does not detect this controller and so far I am unable to get it to work as the grid is completely in negative orientation. so when I sent the machine to origin X0 Y0 it moved to upper left as displayed in Lightburn. When I send it to machine home it moves to -440 in X and Y. so everything I try to cut is out of bounds.
I tried setting the offset to correct but this did not affect that when I select get position after sending machine home I am still at -440 X and Y.
Secondary question is there a way to rotate GUI world origin so the cutting head moves in same direction and axes as arrows are displayed in Gui?
Left moves the cutting head to back, right moves the cutting head to front of machine.
Up to the right down to the left.
Quick and dirty solution would be to Rotate the entire device in the case 90 degrees. I was trying to avoid that as I wanted to keep the controller electronics outside of the encloser, primarily to prevent contamination with metal particulates. The encloser is actively ventilated, so I am probable over thinking this.
Is rotating the grid origin 90 degrees even possible with LightBurn?
First, make sure that you have connected the right stepper motors to the right portion of the controller. Sounds like to me that you have swapped X and Y connectors.
No. Not in the way that you’re imagining.
Also, I’m noticing that you have the Machine Origin set to top-right. Is this explicit? Typically this would be set to bottom-left for most GRBL laser machines and would have been how your original machine was setup.
That is the way my plasma table and waterjet are set up, but I have the A-20 wired as it originally arrived. My work around was to Cut from origin, and set up a camera to monitor the cutting area, and I just set the camera orientation so left moves cutting head left up up and down down. As I have a fiber laser module in the box and never operate it with the door open this works out nicely.
I’d suggest setting it up first to work as expected and then you can customize from there.
take a photo of the orientation of the laser with an indication as to what you’re considering the front of the machine?
change the Origin in Edit->Device Settings to bottom-left dot
Remove work offset:
G10 L2 P1 X0Y0
Home the machine. Confirm that it homes front-left.
Run these commands in Console and return output:
$H
$#
?
Check jogging controls. Do they move as expected? I suspect these will not based on what you were indicating before but I’m hoping that’s a difference in understanding of the orientation of the machine. If not, I suspect a wiring issue.
Create a simple rectangle design and check framing. Does it frame as expected?
It frames as expected and orientation, issue have been worked around, I am running the latest version and to do too case limitations it has to sit the way it sits. The homing matches the graduations as marked on the rails so I am ok with-it’s current operation. What I do find interesting is the manual shows power levels that I cannot set to as well as check boxes that do not exist in the GUI. most likely a operator error as I am very new to lightburn.
Part of the problem in offering a solution is that it’s unclear to me exactly how it’s currently oriented and how it’s been worked around.
Can you take some photos and annotate how things work or take a video showing the behavior?
The other aspect of this is that you’re using workarounds when I suspect the machine could be setup in a way that’s ideal. What specifically are the aspects that you’re looking to preserve?
I think that the AtomStack MR20 included a new controller as the original shipped on the Atomstack A20Pro. So, unless there was manufacturing defect this controller was a direct replacement. There is no way to install it other that the way the original controller was installed, The rails are marked 0 to 440 and the wire harness will only work closest to X0Y0. The issue with homing may be related to the graphics are reversed. I have 2 lasers connected to computer cutting the same artwork on both machines with no changes. The results of that cut follow:
I suspect that the orientation confusion may be related to this issue. I will put the original controller on this machine and recut this art. Maybe I have the beasty put together wrong from day one.
Perhaps it’s electrically a drop-in but still requires configuration. Is the new controller only meant to be used with A20Pro or is it meant to work with multiple lasers?
This may be related to your origin setting being put to top-right.
To what corner of the machine does it home?
Also, can you provide a photo of the machine with a note about what you consider the front?
