Hi,
there is no questions. Want to show my latest project, still in progress:

Arduinos are working with Bascom code.
Regards,

Looks like a real robot arm. I mean not a small desk one. what are the plans for the arm when it is finished? _________________ Mark |

Exactly. I'm going to use it in production proces like " take, move, put".
It's significant difference between making a toy on the desk using modelling servos and using industrial stepper/servos... and in spite of
long TODO list, slowly getting closer
And thank you for nice comment:) |

Looks Good
But i think, you have to slow down speed, if you reach the endpoint _________________ For technical reasons, the signature is on the back of this message. |

I know. This is caused by too small transmission ratio. I don't want to change setup of timer1 which is my square wave generator. Servos should work as fast as possible (to avoid jittering), transmission ratio e.g. 1:20 would fit my needs the best. Unfortunatelly have 1:6 and changing microstepping (greater) also isn't good solution for so small transmission ratio since stepper have too weak holding position capability. Currently I'm working on changing this ratio. |
