Curious with the various Openbuilds CNC kits now available. Why choose one vs the other. which machines are the most ridged for cutting Aluminum.
I have found that the shorter actuators on the machine the better for cutting harder materials like the MiniMill or the C-Beam Machine. This is due to less deflection over all in the machine. That being said I have also cut aluminum on the larger machines as well its really just a matter of more shallow cuts per pass. So it will take longer but it may be that you are working on a larger piece because you are using a larger machine so once you find the sweet spots for each machine they all have their advantages.
