There is a way. I used this https://www.amazon.com/gp/product/B07Q4J4HVB/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
to cut the bed plate support (spider); leveling the build plate for all 3 functions. I downloaded the build plate file that someone drew up here. Imported it into F360. Then made a .5mm single pass path to hit all the raised lands that the build surfaces bolt to. I made the first cut, which hit a couple of the lands. and dropped it .5mm each pass till it cleaned all of them. It took several passes and I had to stop before completely cutting the left rear corner or I risked removing the lands completely. Donāt remember the head speed but it was really slow. The head had to be mounted offset on the axis bracket to the right so that the lands on the right side of the spider would be cut.
I did this a couple(?) years ago so I donāt have the files anymore. But I have no issues with leveling any of the build surfaces. The sensor on mine melted (twice) several months ago so I just manually level it. The only time I have to level it is when I change heads or build surfaces.
EDIT: Make sure your machine is properly assembled, square and adjusted prior to cutting the spider. Also make sure all the axisā are moved by hand to the stops before turning on the machine.
So I downloaded and printed the head, and got the drag knife off amazon and put it all together, but Iām having some trouble figuring out how to cut out a sheet of vinyl using the CNC settings in Luban. Basically, I imported a PNG of the outline that I want to cut, and it seems like itās just starts ācarvingā the vinyl, as it would do for a CNC block of wood, starting at the bottom edge of the image frame and moving back and forth along that area. What am I doing wrong? Does anybody have the time to give me a step by step āfor dummiesā version of what I need to do to make it work right?
Edit -
Nevermind - for anyone that stumbles upon this, the solution was to create a vector graphic and use that. Then use the vector option, which isnāt there when you use a png.
Interestingly enough, a Cricut 12x12 cutting mat fits almost perfectly on top of the CNC wasteboard, and has a slight tacky-ness to it to hold the vinyl down.
Anybody used something like this?
It would require a redesign of the drag knife holder, but is completely possible.
One would use it directly with the CNC attachment, not spinning tho 
Just clamp it in the collet and go, no additional mods.
In Fusion 360 you would need to set offset to the knife, for proper tool path - Cutting with a Drag Knife in Fusion 360 | Fusion 360 | Autodesk Knowledge Network
The process is identical to this with specifics to snapmaker tech - Setting Up & Using Drag Knives | Donek | WorkBee CNC Machine - YouTube
I have created a drag knife holder inspired by gil.a.ramirez that works with the Quick Swap Kit
Files are on Thingiverse:
It requires a compression spring which can be from a retractable ball point pen.
Use the CNC head on SnapMaker
Lower the blade until it barely touches the material to cut as your Origin.
Set your target depth and stepdown to .5mm, 1 pass
Nicely done!
so, did you ever get this to work, using fusion360?
Fusion seems like overkill for a tool path this simple. Snapmaker Luban will work well enough.
because the knife doesnāt cut exactly at the center, the path needs to be different than the thing you want to cut. You need to compensate for the knifeās offset somehow.
Iāve sent you the manual in PM.
thatās a nice write up. thanksā¦ a lot! but did you get it to work with fusion360?
Yep, but drag knife optimization wasnāt as good.
This looks like a great tool for my snapmaker arsenal. Printing as we speak but need advice.
I am trying to cut round stickers, but Iām not sure how to go about lining up the vinyl sheet (which may not be straight edged) and the circles for the cutter. I was thinking of using the laser module so I can use the camera capture to line everything up. Any advice would be helpful!
I am using Luban primarily but also have access to prusa slicer. I downloaded Inkscape, but Iām not sure I have the time to learn the nuances before I need to complete this project.
Sorry I didnāt see this message earlier. Iām confused by your question. Can you please explain what about lining up your vinyl sheet is problematic? Basically I get a sheet, place it on the center of the bed, secure it with tape, and place the cutting tip at the 0,0 coordinates of my cut, run the edges to check the work area and 0,0 work, then let it rip. Depending on how you generated the gcode (if using absolute coordinates) your workflow may be substantially different. Dontā know if that helps, so feel free to reply if you need more help.
The problem for me is that I do not want to cut on a blank vinyl canvas. I am hoping to use it to cut stickers printed on adhesive vinyl sheets. Both the sheets and sticker shapes may be odd sizes, making alignment difficult so I wonder if the camera capture would allow me to lay the printed sheet, align outlines for pathways, and then replace the toolhead with the cutter. Your thoughts and experience are greatly appreciated.
In theory, it should be possible.
You could camera capture and align your models in the workspace coordinates.
Camera capture is only used for alignment, after generating the gcode it should be possible to use your cutter-tool.
I am not sure how precise the alignment would be but check it out and let us know, please!
I agree with @xchrisd. It may be possible, but I have never attempted to print multiple stickers on a vinyl sheet that have to align with precut shapes, and I do not use camera capture very often because I donāt have it set up and calibrated to work in Lightburn.
Vinyl stickers I usually cut on a blank sheet, or, if I am printing an image and cutting it out, I set up guides (tick marks at key corners of the sticker) to use as a guide. Let us know how it goes. We are always looking for better workflows.
