I previously had my mpcnc built up 1127mm x 837mm with the standard C build conduit and had added mid span supports to both sides. I’m reprinting now and have 1"OD 0.065" stainless steel tubing, and have dropped it down to 1051.56 x 797mm. Just wondering if I should add the supports, at least to the longer axis. I know it says to add them to anything over 1M, but this is pretty close, and using the stronger SS tubing.
Can’t hurt.
