i thought it is o good idea to add i pi with ros installed on it.There are libs available to communicate with ardurino and also to calculate kinematics.Pi will have enough processing power to do so.Will see if i get it done this way. Actually still printing. (I am at the 3 axxis.)
I have orderd thor stepper boards from pcbway they will come this week. ;
All other hardware is in place. As soon i get the boards i will start comissioning electronics and generate software.
