As a followup to my last post....I think I may have solved my own problems.
I looks like the steppers don't have the power I need as I can grab the ball screws and stop them with my hand.
My thought to correct this is to add a gear train in the ratio of 1:3 so as to increase the torque of each motor.
I would guess that I also have to make some changes to the program to increase the steps per inch to account for the change in speed and turns per inch.
Has anyone else had this problem...and do you think this is a correct way to go? |
