Yay, have my reworked Prusa i3 up and running and have been printing for a bit…yet could use some input on Marlin firmware settings.

I’ve been playing with the various movement settings. I’ve gone through several threads online and right now I’m running probably too conservative, but I learned quickly why defaults don’t work.

Printing at 80 mm/s sounds like you’re rolling on/off the throttle of a miniature 2 stroke with the way the motors accel/decel.

Any links or advice appreciated…TIA

you missed to put the link :wink:

Most excellent…thx. Worst part though is I’m a subscriber to @Thomas_Sanladerer 's channel and I didn’t recall seeing the vid (prolly due to 3D printing info overload).

I run my at 60 with very conservative acceleration and jerk.

#define DEFAULT_MAX_FEEDRATE {200, 200, 3, 45}
#define DEFAULT_MAX_ACCELERATION {2500, 2500, 100, 10000}

#define DEFAULT_XYJERK 10.0 // (mm/sec)
#define DEFAULT_ZJERK 0.4 // (mm/sec)
#define DEFAULT_EJERK 5.0 // (mm/sec)

thx @Richard_Mitchell , have them loaded and doing a test print. Movement already seems better.

Glad it’s working for you. Very conservative but I wanted reliability over speed.
