Custom Robot with Nema 17 and the A4988 driver

Hello guys

I Would like to build a robot with Nema 17 motors and A4988 and it worked but the motor sound not nice and sometimes when i play with the speed and the ACC speed they miss stepps. What for configuration can i do in the Arduino sketch and in the AR2 programm to stop that. I saw a lot for Persons on YOU TUBE where using that configuration. Please Help me i spend a lot of time in my stl configuration and i know my english is not that good because i am a german student (-:

I would start with raising the speed multiplier at the top of the ARCS sketch and see if that helps to alleviate the 4988 driver missing steps.
