Please hold a coin in front of your eyes at a distance of 30cm. Now bring it closer to yourself by about 130mm. It appears larger, doesn’t it? It’s the same phenomenon. The object appears larger because it is closer to the camera, causing a shift in its position and resulting in a larger projection.

Thank you, how can I work in collaboration with the camera and high objects? Does anyone have a solution.
My assumption is that you would have to redefine the position of your camera(when it takes pictures) to be higher, including the entire bed. Then run the camera calibration and alignment wizard from the new perspective. You should then have a properly aligned camera for high objects.
What a ride. Drag and drop is amazingly reproducible on my machine now. Attempting to use inline power with grayscale images. I’m still running into a single issue, and that is of burnt edges. I seem to still be getting some sort of stop or deceleration at the end and start points of my lines. Any idea of what might cause those burnt edges?
Firmware version: Snapmaker_V4.34-SKREE_2023031
Touchscreen version: V1.15.12
Grbl version: GRBL-M3 (1.1e or earlier)
No overscan, G0 for overscan turned off, no S values emitted
Fast whitespace scan on at 5999m/m
I have my typical engravings going at 3000m/m,
trying to get the value as close to the limit of 6000m/m to truly take advantage of the 10W laser. The quicker I go, to more visible the burnt edges are.
Apologies if any of the version/software info above is irrelevant, I am not as well versed as you and not quite up to speed on where exactly this issue might be arising! The past two days has taken my laser from a machine that was a process to get started, to a machine that truly has a smooth workflow thanks to the community and your posts specifically. Thanks Skreelink!!

In your engraving settings, turn overscan on. (leave the machine settings G0 for overscan and Emit S0 off.) Faster speeds need slightly higher overscan. Around 5% should be fine. The burned edges are the head having to come to a stop, then speed back up in the other direction, but the laser stays the same power. Overscanning turns the laser off and lets it go past a little bit for the slowdown/speedup movements so it’s more consistent.

Awesome, thanks for the response!

Where did you get Firmware version: Snapmaker_V4.34-SKREE_2023031?
Should be one of popular links just below the first post on this thread. It’s on github for download
I can only find Snapmaker_V4.5.34-SKREE_20230319.bin_20230319.bin.
Maybe link please?
The 9 is just being cut off on the about screen. 
Your own picture from an earlier post shows it as well.

Oops… Duh…My bad, Thank you. (head hanging in embarrassment)
Once I uploaded your firmware to my A350 with 10W the Z coordinates on the machine now read the same for both machine coordinates and work coordinates, at home Z is 334.00 for both. How do I determine my focus height if these are the same? Thanks for any help y’all can provide!
Since I was setting up my 10W for Lightburn and had probably read this thread at least twice, I decided to try to summarise Skreelinks fantastic guide and support advice he’s provided on this along with the other contributors into a single document. I’m posting it here and will also add it to the Guide Link. If you feel that there is anything else to add or correct let me known and I’ll update it going forward

Has anyone used the material test that autogenerates in lightburn? I’ve gotten fairly good with control of the snap maker in lightburn but I have been trying to use the material test on a very thick item and I can’t set the material thickness for the purpose of the test, I have had several collisions trying to make the height work correctly. Any suggestions?
Have you tried having a project open (simple shape will do) with the material thickness selected, then run the material test? I’m not 100% but I think it picks up the value. Unfortunately I’m not at home to check
@Burgerboy is correct, place an object first and you can set the height as normal. The material test should pick it up. Otherwise, you can always open the gcode and put in the height yourself. I’ll post an example when I can.
nice work!
I’ve converted the docx to PDF for those without access to Microsoft Office and added the file to GitHub - shurushetr/awesome-snapmaker: Curated list of things that help you make something awesome with Snapmaker machines.

Looking to understand something here.
My understanding is the core problem this guide solves (correct me if I’m wrong!) is inline control of the laser that specifically improves grayscale imaging in Lightburn (something I was experimenting with yesterday).
It sounds like inline control has been enabled in the stock firmware, does that mean it is no longer necessary to flash custom firmware to control the laser? If that’s the case, then using GRBL setting in Lightburn should work with the stock firmware (which is how we adjust Lightburn’s gcode to account for inline power, if this is indeed the case feels like we should open a ticket with Lightburn to support inline in Marlin).
I just updated my firmware to latest stock, and was trying to test my theory by doing the following
M03 S0
M03 S2.5 I
G1 X1 Y1
However with this sequence of commands the laser does not turn on. Is this a valid test of inline control of the laser? I feel like I’m missing something. I did also try adding S into my G1 command with no luck either.
Hoping to do greyscale engraving without needing to flash firmware, thanks for any help!
