At the moment I can not find an alternative to the trinitylabs set : 10 start 25mm pitch fast lead screw and nut.
Tank you to Cary Beaty for his discovery, which seems to be a good alternative to Trinitylabs set. I do not have time to test, or to adapt the design with these screws, but I hope someone do it :) http://www.mooreinternational.co.uk/category-32/SPEEDYSTANDT12-25screw.html
Half speed, 1/4 the price, but to short, 200mm : 10 threads per inch and has 5 starts, 2 turns per inch. http://buildyourcnc.com/item/mechanical-leadscrews-leadnuts-!5-5-starts-10-tpi
If any one know any other providers, I would be happy to know.
Others way could also be considered, such as threadless ballscrews
To do? or not to do?
- Better implementation of endstops.
- Change the extruder for a geared version.
Change NEMA17 3.6 kg/cm by 4.8 kg/cm for X/Y- Done!
Speeds and quality tests.- Done...
- Find less specific alternative lead screw.
- Build instructions. (10%)
