Option 'max_accel_to_decel' is not valid in section 'printer'
I did a software update and getting the 'max_accel_to_decel' error in Klipper. See the other posts about this option depreciated and to be changed to minimum cruise ratio.
Found 3 reference to the max_accel entry in the printer.cfg in the /config root folder. 2 under Base Setup and one under the Stepper motor, drivers, speed limit section. Changed them to the minimum cruise ratio, save restart, reboot, power down/up. Still getting the error. Example of the section in the printer.cfg file entry below. Not sure if the setting is not replicating to other config files or maybe missing another location to update. Could use some help hear please?? ideas?? ############################################################################################################# BASE SETUP ############################################################################################################# [include config/printers/v-minion/v-minion.cfg] #[printer] #max_velocity: 400 #max_accel: 5000 #minimum_cruise_ratio: 0.75 #square_corner_velocity: 5 #max_z_velocity: 15 #max_z_accel: 200 #[printer] #max_velocity: 400 #max_accel: 10000 #minimum_cruise_ratio: 0.75 #max_z_velocity: 15 #max_z_accel: 300 #square_corner_velocity: 5 STEALTH MODE NOTE: You still need to include one of the above stepper motor definitions.

If you update ratos, those depreciated things shouldn't be there.
You also should never edit any of those files other than printer.cfg
ratos has been updated. it was a pretty old version though and wasn't sure if i upgrade out of order or something

no worries, try restarting the machine first
Then the files that shouldn't be edited will be fixed I believe.
Also, then SSH in and run
ratos doctor
, might help fix if the upgrade went awryThanks, did a klipper restart, host reboot, and power off/on with no change. Ratos doctor require login? Having trouble finding the login creds. Been over a year since I ran the minion and afraid I might of lost it.
its
pi
/ raspberry
by defaultthanks i guess i didnt chang it. is there is specific syntax or folder level for ratos doctor? doesn't appear to like it

found the ratos-configurator folder but getting the same. command not found
How old? Like what version of Rat-OS
1.2.4-1 i believe
was before update
Yeah, you can't upgrade from 1.x to 2.x
ohhh, that won't
ratos doctor
, it is too old to have been able to update to 2.1 on it's ownTime for a fresh install
thanks will give it a try. might be tomorrow before i got time. think i see the links below

This is preliminary documentation for the upcoming v2.1.0 release. The work is still ongoing and the documentation is not yet complete.
Imagine I should backup the printer.cfg. Any other files?
Back it up for for reference, but you won't be using it directly.
Thanks TheTik
