Travel very slow

Am running Marlin (2 weeks old git clone) on a minitronics board. But every time the head needs to travel and not print on the x&y axis it does this with 0.1mm/s (guess). Am really puzzled by this behavior as when it's printing there is no problem.


My edit's in the config are as follows:
#define MOTHERBOARD BOARD_MINITRONICS
#define TEMP_SENSOR_BED 1
#define X_MIN_ENDSTOP_INVERTING true // set to true to invert the logic of the endstop.
#define Y_MIN_ENDSTOP_INVERTING true // set to true to invert the logic of the endstop.
#define Z_MIN_ENDSTOP_INVERTING true // set to true to invert the logic of the endstop.
#define DEFAULT_AXIS_STEPS_PER_UNIT { 800, 160, 8000, 1666 }
#define DEFAULT_MAX_FEEDRATE { 300, 300, 2, 500 }
The rest is default.

Sliced in cura which has
print 30mm/s
travel 120mm/s
printed by octopi (same issue in cura and pronterface)

EDIT2:

I forgot to mention all the stuff i have tried:

• Check voltage drivers
• Check temps drivers
• Added custom heatsinks (just to be sure)
• Clean clone
• Clean flash
• Disable thermal runaway check
• Temps are stable

So i took a step back and it hit me: Maybe it's actually that it's to fast and the motor/driver can't handle it.

Ill report back tomorrow

Why the different values for X and Y steps/mm.
What micro stepping are your motor drivers set to ?

the numbers are also very high, a poor 8 bit ardunio is going to struggle, especially on long moves.

Well this seems to have fixed the problem but as written by obewan & dust source might using 1/32 stepping.

Am using a threaded rod for X and pully's for Y. Made this change because i wasn't happy with the quallity

I believe am running 1/32 stepping. I had to double all 1/16 values to get the mm/steps to line up.

Hmm perhaps i should look into dropping from 1/32 stepping to 1/16.

I would try 1/4 stepping on X ie 100 steps/mm much more reasonable for a arduino
