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 (-:
Okay nice its works but can i also do that with the A0 and A1 pins on the arduino i tested it and it makes no steps i have change the vaule but it must work because on a ramps board it also work ?
I will test it in the afternoon and then i give a feed back and then we see.
Thank you for help i will test as fast es possibile
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.
