Setup of 10W Laser for Snapmaker with Lightburn

LightBurn Hardware Compatibility Snapmaker

Hi

I looking for some help setting up my 10W Laser on my Snapmaker2.0 A350 with Lighburn.

Snapmaker doesn’t seem to have a device file to import. When I setup my Infra Red i could import snapmaker2.0-2w(1064nm)-v1

I used @Skreelink guide ( 1064nm IR+20/40W + Lightburn Guide) which was amazing (thank you)

Snapmaker guide (Adding a 1.6W or 10W laser module in LightBurn | Snapmaker Wiki) didn’t even work.

Can anyone help with the device setup (manual) and the Start & End GCodes I need. Especially how to calculate the absolute work origin calculation i.e. G92 X-23.5 Y335 Z287.9

Finally Can I use one of the device files for 20W / 40W and tweak it (Using Ray/Artisan/2.0 with LightBurn | Snapmaker Wiki)?

Thanks in advance

Si

I would think you just add manually under devices and follow device wizard. You probably use GRBL

You can use the same guide for the 10W, do a many ‘touch focus’ on the bed, and when it moves up, that’s the “focus bar” length you’ll use.

Cheers. I managed to sort that, but it was all the option in “Device Settings” especially the GCodes especially the absolute coordinates caluation. The Z one can be a tough one

Thanks for reply.

The only option on the 10W is Toolhead Focus Calibration. It doesn’t have Focus Bar like the 1064nm IR.

If I use Toolhead Focus Calibration do I grab the Z Coord from the Control Page (attached image) and minus from my original of 319

319 - 23.7 so my Gcode would be 295.3

Gcode example
G92 X-19 Y332 Z295.3

Thanks

With the 10W, start a project, then do a manual focus (where it asks you to touch the toolhead to the material) but just touch it to the bed and hit next. When it moves up to set X/Y origin, back out to the main screen and record the Z from there. It should be around 30mm-ish.

Thanks for coming back. Sorry to be a pain, I assume you mean on the Snapmaker touchscreen. Where is the manual focus. I have the Toolhead focus Calibration but once it set it doesn’t move. If I go back to the Control it shows 23.5mm (Quick release tray installed so that be why its not 30mm)

Quick release shouldn’t change the focus height. Yes, I mean on the touchscreen. To do a manual focus, do some project in Luban, doesn’t matter what it is, we’re not actually running it fully. Load it onto the USB drive, then on the touchscreen, click start > select the file you just put on it > when it offers to focus, click manual instead of auto (auto uses the laser). It’ll prompt you to move the toolhead down to touch your material. Touch the nozzle to the bed directly, click next and it’ll move up.

Afterwards, tap back all the way to the home screen, then check the movement screen.

EDIT: Also you’re not being a pain, it can be confusing. :upside_down_face:

Oh that makes more sense. Followed everything but still getting a lower reading of 21.40mm.

The X is 31mm but not Z

What am I doing wrong. :shaking_face:

Thanks

That’s fine. Now you know the actual height of focusing on the bed. Could be a difference in manufacturing. :slight_smile: I have a really early unit. Plug that in and test it out!

All sorted, @Skreelink thanks for all your help.

I have it all written down if anybody wants it (with screen shots)
