Hello I’m new here and checking all 3 models I see that difference is on the size of working space only? Or they have others differences, any other factor I should take on account between small one and large one? Talking about capabilities
As far as i know the only difference is the size. As far as which one that depends on what you want to do.
the smaller the machine the more rigid it is. the harder the material you cut the more rigid your machine needs to be. if you plan on doing larger projects and cutting non-hard material is not a problem then get the larger machine. if you plan on cutting hard material on small projects then get the small machine. If you plan on cutting hard materials and need a larger size then make some modifications to make the machine more rigid and cut slower.
Only you can make this choice.
