curious errors after converting INI from MM to Inch

well... same issue, same error.
I changed some values regarding the acceleration, and i got further travel, but very slow acceleration, so i moved them back, and it brought about the error again.

I am starting to wonder if it would be wise to wipe the configurations, and re-run the step config. then i can replace bits from the current configs, a little at a time, just to see where i went wrong. seems like a real PITA, but i don't know what else to do at this point.

I checked your .ini on your github link.

MAX_ACCELERATION = 5.04
STEPGEN_MAXACCEL = 4.56 <= this should be 25% higher than one above

Than create new similar config with stepconf.
And look what is different.

so, here is where i am at... i tried creating a new configuration, and it was working great, with the exception that a move of 1 inch, caused it to move about 3.5 feet (roughly).
so, i have a 200 steps per rotation stepper, the drivers are all set to 1600 pulse (microstepping setting of 8? and the pitch of the ballscrew i think is 5mm.

i had 200 set for the steps per rev, microstepping of 8, ratio of 1:1 (direct drive), and (don't remember the setting name) was set to 127. (revs per inch?) i arrived at 127 by 5mm_pitch X 25.4. i also tried the result of 5 / 25.4 (0.1968), with no better results.

my mind is so frazzled, i wonder if i should have even converted to inches. but the problems i had converting from inches to mm in the G code, seemed to out-weigh the conversion process (so i thought).
other than existing, what am i doing wrong?
