Ender 3 Jerk Settings

Hi,

I'm currently using 4 ender 3's hooked up to Repetier Server. Using the EPROM section for each printer I can define max feed rates and accelerations but can't see jerk settings. I've tried issuing a 'M205 X8, Y8' command followed by 'M105' and when I request a readout it still shows the advanced settings with no jerk defined. 

Any solutions how to solve this, as I'd like to reduce my jerk and bump up my acceleration. 

Kind Regards,

Sam

  • Try with just

    M205 X8 

    this sets X and Y jerk to 8
  • null
    Have tried M205 X8 aswell and it still doesn't show when I try to recall the EPROM settings via the command line it doesn't show it.
  • In eeprom you only see what M503 returns and only if it is defined in the extra/eeprommap/marlin.xml file with proper detection string. If it differs it will not be included.

    What is the output on M503 for your printer. And can you please mark the part not showing up. I then check and update the map file.

    M205 Line isn't updating XY jerk settings, even when I send the M205 X8 command.

    tells clearly it has no X parameter, so X is not supposed to work. J seems to be for junction but value is small so not sure what it means here. Marlin is not my firmware. Maybe they disabled changing jerk for x and y.gcode definition on reprap org says
    Sprinter / Marlin
    Minimum travel speed = S[printing] T[travel]
    B[min segment time] X[max XY jerk] Z[max Z jerk] E[max E jerk]

    just like you try but M503 says it is no eeprom parameter.
