Arduino " Accelstepper.h " library

[NHSA]

Hi,

Maybe some have read my posting about the robot arm I am building

Need a programmer against payment for programming my robotic arm

Hi, I am new here and after I just finished building my robotic arm due to an idea of a friend who wants to play chess with it and now somehow he got cold feet in regard to programming it. Yes, Sh… happens as Forrest said. I have a modest budget around US $ 100.00 and perhaps could go a bit higher according to the quality of the program. The program so far at the moment should NOT be able to play chess. Just for moving it via a GUI from a PC and perhaps as second alternative at the same time …

I have been testing motor by motor with an *.ino script using the accelstepper.h library.

Has somebody experience with this library and seen that the step over from acceleration to desired speed has a jerky point ?

What do you recommend in order to get rid of this ?

I have experimented for example acceleration 500 steps/second² as well as 1000 steps/second² with speeds 600 steps and 800 steps which according to the motor manufacturer recommends according to their Torque graph for the motor 17HS19-2004S1

Thanks for any tip and regards Rainer
