I’ve been working on this issue for months, I’ve finally decided to seek help from the community.
I have a 2.0, A350 with 40W laser and quickswap.
I set the work origin to be bottom left, and ensure size is within limits, but the top is cut off. It’s driving me crazy. It seems the workpiece size does not match up with dimensions.
Has anyone figured out the maximum workpiece size with the quickswap and 40W laser? It’s infuriating that I can’t rely on the advertised limits of the machine, using Luban, and selecting the correct accessories. For example, if I’m lasering a square of 340x340, it will still laser a square but it will come out as 340x330, giving no warnings or errors. I had initially thought it must be to do with the origin being in the center instead of bottom left, but it’s not the case.
The attached file looks weird… I’ve been putting the ‘cut off’ violin shapes on the ceiling, you can see the top off the shape has been cut off with a straight line.
That said, you can “squeeze” a bit more from the machine - you already get 340 in X it seems, and in Y you can also get a few mm - see here: Maximum Y Position 347mm?
And of course you gain another 15 mm in Y if you unscrew the QSK.
Indeed you will not get any warnings - the movements will just stop at the maximum point and continue as if all was fine… This will cause exactly your problem.
That said, I agree that Snapmaker does a poor job of giving correct dimensions and sizes… The Snapmaker 2.0 shop page even claims 350x350 mm work area in a very prominent way:
Thanks so much Hauke and Wyphorn, I really appreciate it. I don’t know why I didn’t find that table previously, maybe because it’s presented under the bracing kit option which I don’t have.
It blows my mind that such a sophisticated product (in many ways) that asks which accessories you have (eg quickswap kit) doesn’t take care of the boundaries / max workpiece size when using their Luban software. I really love my snapmaker’s (I have 2x A350’s) and don’t even mind the many quirks, but I struggle with this issue. I’ve always used the centre origin setting, but when trying to use close to the max workpiece size of the machine, I haven’t been getting consistent results so have started moving to bottom left.
I’m going to give it another go at trying to figure out my machines maximum area, along with documenting the steps with photos, so that I can rule out what is my brain problem and what is my machine. I’ve got an acquired brain injury from an accident so I struggle with math and x,y,z issues but have a background in IT so have the mindset that I can figure it out eventually.
Thanks again for your reply, I’ll post some more info here on what I find along with all the setup in case it helps someone else.
