Software/hardware parameter limititing print size

Hi,
I've been trying to print some masks, but the printer is cutting off the edges on both sides as if it's hitting a limit.
I'm not sure what to change, there is plenty of room left for the mechanicals to move.
Here's a pic of what it should print.

and here's what it's printing:

Probably something simple, I've tried changing print area in MatterControl, and recalibrating the H2, I have the long arms installed.
***update***
After 5 hours of firmware updates, recalibrations, and a bunch of test prints, I think I'm back to factory default... :shock:
The cal wizard values are all 0.03 or less now however.
Here are my EEPROM settings exported from MC:

That doesn't look like the behavior I'd expect from hitting the firmware limit on printable radius. Does the STL get thinner there, potentially thinner than the nozzle? Are you sure the STL is manifold?

The MatterControl program "knew" where it was going to limit the print, because the skirt was shortened at the sides also.

That doesn't mean it's not a problem with wall thickness or STL quality.

Can you post the STL or G-code? It may very well be that the slicer has a max radius setting, which may be the issue (If it's mattercontrol, which it looks like, IIRC, it does have one). It can also be that the slicer is choosing to ignore an errored, too thin, or otherwise unprintable area. This looks to be the case, as it appears that the lost chunks are not along a smoothly described radius, but instead are rather roughly and triangularly removed.
