REAL print area?

Greetings!
I was playing with my MAX (V1) this weekend, and decided to "go for height". I made a 14" high cylinder 1 1/2" diameter. It printed it, but just barely- the limit switches were being "kissed" on the last layers. So if it gets 14" high with a 1 1/2" piece, then it surely won't get there with anything wider than this. The wider the piece, the more offset of the arms. So what's the REAL print area? 11" x 14 1/2" is misleading.

Print a single wall cylinder (use continuous Z or "vase" mode) 6" in diameter and 14" in diameter. You tell us.

This is a great question and the answer can be calculated. Keep in mind also that the "cylinder" is not truly a cylinder, the X-Y plane greatest extent is a actually tri-lobal. The 11" diameter circle is about the largest circle you can put inside this tri-lobal area. None of the current slicers are sophisticated enough to deal with the actual geometry of a delta so these sorts of simplifications are made. This also applies to the Z. It is not a simple flat top. As you've discovered, it is domed - but it is also not a circular dome, it is a tri-lobal dome like the X-Y cross section.

I'm sure I could do the math in less time than it would take to do that print
Thanks for the explaination, mhackney - it seems obvious now from the mechanical constraints.
If I set the head out to maximum diameter, and just move it up in that position until it hits the stop, I should be able to get the max height of max diameter.

Yes, that is a good way to get the max height at the periphery. Let us know what you get and also report your Z heigh overall.

Actually I was curious myself. Post what you find out please!

If you want to build taller, buy taller extrusions, belts and bowden tube like I did. 36" build height means never worrying about being too tall to print.

I'll figure out the width\height specs this weekend and post it here.....sometimes work gets in the way of my playing, but that's OK because I play with even cooler stuff at work!
Extending the extrusions sounds like a good idea!
