Thanks for the extra comments, they indeed help, and I will be playing with this very soon, to get it working well will be a bonus. What's become very clear is that there is a lot more to the Delta...
View ArticleWhy is filament line better than belts?
QuoteIn addition, we use spectra fishing line which produces higher resolution prints than using belts. Can I ask another newbie question here, while I can see that belts may wear, and have a bit of...

View ArticleRe: Why is filament line better than belts?
I don't think that spectra gives better resolution than belts, as long as the proper belts are being used. I think the main reason for using spectra is that it's significantly cheaper than belts and...
View ArticleRe: Need advice on motors for Kossel build
Those motors all look a bit under-powered, but may work just fine for a Kossel. I would be a bit worried about using one for the extruder though. Generally you want motors that are less than 3Ohm and...
View ArticleRe: Need advice on motors for Kossel build
Thanks. So I need to look at less than 3 Ohm and 2 amps and under 6Volts. Isn't the holding torque the important thing? So many variables to take into account. What is an example of an affordable...

I've built two printers so far with the motors in the first link and they work fine even in an extruder. The only catch is that the shafts are 4mm, so you'll need to make sure your pulleys and...

Dudesom, you might have some success with ultrasonic welding. I think you're going to have difficulty getting the metal to adhere, though. Check out thermosonic welding. It's the process used to bond...

Nice idea of cycloidal gears. They worth to be tried and are very well suited to all this almost frictionless DLCJ stuff. I l ike them.

Re: New arm design for Simpson style printer.
Since cycloidal gears are not your everyday tooth form, I had to make a generator. (You can approximate a cycloidal gear with arcs of alternating concavity. I don't think that will be good enough for...
