curious errors after converting INI from MM to Inch

unfortunately, i both updated from 2.7.0 to 2.7.14, and loaded the converted INI file at the same time, so no telling which change caused the conflicts. i highly suspect the errors are from my INI file changes, so we will work with that.
all my config files are on my GitHub, here: github.com/travisfarmer/my-linuxcnc-conf

after homing the machine, (slow but it seems to work), i intended to verify my software limit settings by jogging toward the extremes, and noting where the machine stops. i only got as far as testing axis Y (AXIS_1). the MIN limit worked perfectly, though when i jogged toward the MAX software limit, it moved a bit over 4 inches, and shut down the machine ("Joint follower error" i think).

it is extraordinarily stupid of me that i didn't save the INI as a backup, per-conversion from MM to Inch. i think i can roll back my GitHub, but i am not keen on that, just yet. perhaps some more eyes on the configs will spot something.

Thanks in advance for any help.

Traj
default velocity is higher than max velocity
Same on display section, 9 and 90
There are no entries for stepgen_max_velocity but it should work without them.
I see no other issues there.

ok, thank you very much! i will be heading back out there a bit later, and will try the changes.

Same issue as before. here is a screen cap, if it helps. note error in lower-right of Axis.

Take a look at the section of .ini where it says which velocities should be 25% higher.
As you might have them same value as your normal velocity, and that can lead to that error.

ok, sounds good. i have set the max velocities to 25% higher. i will test them tomorrow, as i have not installed lights in the CNC shed yet, and it is now dark out.

thanks for the fast response!

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.
