Slic3r speed too high

Hello everyone,

My slic3r speed is somehow way too big. If I set all speeds 10 mm/sec in the speed tab in slic3r, my printer still moves like it is 50mm/sec. However, if I make it 80 mm/s or so, it moves fast, as it should. What could be the issue without being able to print low speed? Here are my Marlin parameters

#define DEFAULT_AXIS_STEPS_PER_UNIT {80.00, 80.00, 2133.3333, 808.6183} // default steps per unit for ultimaker
#define DEFAULT_MAX_FEEDRATE {500, 500, 50, 500} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {9000,9000,100,10000}

Thanks

You think you can achieve 500 mm/s and 9000 mm/s²? That's bold

That said, a firmware just executes G-code and doesn't create it. To evaluate/debug a slicer you should look at what G-code it generates.
