Hi. I’m at the low level of the community no prior knowledge and just putting things together without planning and seeing if it works. I’m probably going to ask a stupid question but hey a fool you asks is a fool for five minutes a fool who doesn’t ask is a fool forever.
This is my current build (I can move everything around if needs be). There are two stepper motors marked 1 and 2 in the picture. They are running off the same code so speed and steps are identical. Everything works fine initially but then after five minutes the film near 2 starts to get tight and pulls the reel off.
My question is, Is it because of the “pulley system” that number 2 has more torque and therefore creating more tension? Is it as simple as increasing the steps on 1 to create some slack?
Hopefully this will aid a DIYer in the future.
