B2X300 Lead screw

What's the pitch of the printers lead screw? The bee prude was m5 therefore 0.8mm per revolution. Lead screws usually have a much larger pitch therefore potentially loosing resolution

Hi @RickRick!
I believe the pitch is 2.0mm but I don't think it means a loss in printing resolution/quality.
The lead screws in the helloBEEprusa were cut to size from longer screws and that means that some times the lead screws were a little bent, that shouldn't happen with the new machined, wider lead screws. Besides, the new stepper drivers have way more precision and more microsteps and that should produce a significant increase in printing quality :D

Atlas 10100 lead screw question.
Yeah one of the little blue lathes followed me home.
As I look at it the lead screw seems to be a 1/2X20.
Shouldnt it have an acme screw?

Hello Warnerhoalk,

The leadscrews on the B2X300 are trapezoidal with 8mm diameter and a 2mm pitch for reduced backlash on the Z axis. Acme leadscrews are for imperial units, we use metric screws.
