No problem. Did you fix the issues, or do you need more assistance?

I have a driving gear of 36 for a 84 tooth gear, but the arm will lift up for a minute or so then just wont lift anymore; could I just not be using enough securment for the gears?

Xenon27 · February 1, 2020, 4:28am

your ratio is too greedy. try 12 tooth to 84 tooth.

350811g · February 1, 2020, 4:32am

So if I switch to a 12 gear then it should add more torque for the system allowing for more power right?

Xenon27 · February 1, 2020, 4:33am

yes.
a 3:7 ratio just isn’t strong enough, especially with one motor.

Oh sorry I forgot to mention I have 2 motors running the lift system does that change anything?

Xenon27 · February 1, 2020, 4:35am

not really. you’d have to have pristine build quality for that kind of ratio. perhaps it’s possible with 2 100 rpm motors, but I wouldn’t try.

since you do have 2 motors, you could try a 1:5 ratio, that will be a bit faster, and two motors can certainly handle it.

Ok, Thank you for your time and help
