Hi William, our email is still active should you need to get a hold of us for things of this nature. I believe it is posted at the beginning of the thread.
As for your dilemma, there are multiple places you need to update settings to reflect your new build volume.
For starters, the EEPROM on the printrboard itself, must be updated to reflect the new travel limits. M211 should be set to x203.2 y203.3 and the z should be changed if you also installed the z10 upgrade. IF you are using the firmware we suggested, you will also want to make sure that the m212 x value is set to x0. As this offset tends to screw with the probing if it has a value other than 0.
The settings for various control software and slicing programs vary, however it shouldn't be too difficult to find the relevant areas in each respective software.
Something to keep in mind, any gcode generated in a slicing program while your bed was laid out at 6x6 will still run, however the prints will be positioned off centre on your table, due to the fact that your previous slicing profile would have assumed the centre was at x3 y3 instead of your new centre which would be an inch away in each direction respectively.
I hope this information can sort out your issues and get you printing some large parts
(or a lot of really small ones in one shot )
If you are still having some trouble, by all means email me and I will get back to you as quickly as possible.
