Ok, even worse with other releases. It seems I'm stuck using the Printrbot source, same issue plus some with other releases that aren't printrboard specific. Here https://github.com/Printrbot/Marlin/...ot-prod/Marlin is the exact release I'm toying with, and I would really like to figure this one out since the other candidates give me grievous errors.

I'm going to try two things until someone can interject a better idea, I'm going to look through the Marlin master (https://github.com/MarlinFirmware/Marlin/tree/RC/Marlin) and see if there is any different definitions or calculations for xyz_max_lenth/base_max_length, and I'm going to look through the first source for similar. Call it a frustration move, not sure where else to go, I much prefer using a Marlin flavored hex over others, especially because the others I have tried give me oodles of convoluted compilation errors.

I will report anything interesting I find, hopefully I find a pointer to something I can adjust.
