The boards im using are mega 2560 and ramps 1.4 with marlin firmware on them.

After figuring out the right axis steps per unit for my 3D printer using calculator.josefprusa.cz, i have came to a conclusion that the best working number for my x and y axis is 5 instead of 80, this is so confusing and i know for sure that this is not correct since i am using 1/16 steppers and in my configuration_adv.h file, the microsteps has been defined as #define MICROSTEP_MODES {16,16,16,16,16}.

What is the problem?

... are the microstep-defining jumpers set correct?

I dont know, how should i check?

"... are the microstep-defining jumpers set correct?"
since i assembled everything according to ramps 1.4 catalog, and all the stepers are working, I think it should be correct.

I think for 1/16 steps you have to install all the jumpers under the motor driver chips.
Did you install all 3 jumpers under the driver chips?

Thank you for your reply but i dont understand what you mean, i followed everything according to ramps 1.4 catalog and google pictures, all i did was basically to insert my Pololu A4988 drivers into their place.
Did i have to do anything else than that?

Check out the picture. You have to have these three headers installed under the drivers for 1/16 stepping.
Do this with the power off obviously.

Probably no jumper is installed, which makes it full step, which is 5 steps/mm indeed. 5 * 16 microstepping would be the desired 80 steps/mm.

Floyd and MPower, thank you so much for your replies,
i checked and i realized that i dont have any jumper caps installed.
i will go head and buy them today,
Thanks again

No worries. Simple thing to overlook.
