I was looking around in the Marlin firmware for a setting to allow me to adjust the jog movement. I did find the line below and changed the value from 400 to 800 but that didn’t seem to have any evident effect so I reverted back to the original value.
Configuration.h:
#define DEFAULT_TRAVEL_ACCELERATION 400 // X, Y, Z acceleration for travel (non printing) moves
If anybody has done this themselves and could point me in the right direction I would certainly appreciate it.
