Hi there, I'm experimenting with delta's ... made a large one, and maybe the arms+effectors are a bit too heavy for the NEMA 17 + A4988 combination. [imgur.com] I cant make it lighter (actually, it...

Hmmm. Didn't think of that. I'll check that out first. Its seems highly probable.

I've got a similar problem with a 100:1 nema 17. The motor will turn without the gearbox but with it on it won't budge. I even opened up the gearbox to try and clean it out but that didn't help.

yes, they're on their way, though, they might not be enough. Bought a bunch of 80g fishing weights, will try :-)

I've used counter weights on an Ord bot before, since I converted it to belt drive. I used pretty heavy fishing weights myself. Here's a link to my page: [www.thingiverse.com]

I've run a 1000mm tall, 500mm wide delta with 50oz.in motors without problem. It doesn't take that much effort to move the effector, notice that all three motors support the weight of the effector...

Thanks for the feedbacks. Some clarifications on why it's built like that / what i want to do with it. The effector will become much heavier, probably around 1Kg, as i intend to print with pastes...

The delta printer working area is not a cylinder, it's like a rocket shaped at the top. This means that you can't print your max Y or Y sized objects all the way to the max Z but a little shorter....

Hey sheepdog43, i'll probably get some swinging because of the inevitable little offbalance of the weights and build not so rigid (the belt alone gets a little bit of swing), will post a pics/vid with...
