Re: G-code interpreter/stepper controller

Ok, I understand. I was only considering full step. I should probably
go to half step at least.

I read a lot about the physics of stepper motors and the way to drive
them, about the advantages of microstepping, etc. but I am designing a
simple, versatile and affordable system (well... compared to $150 per
channel for a gecko drive); so I decided to forego microstepping in
favor of simplicity of design for now. It should already have some
applications as is. Current tests are very encouraging, and I think
that there is a use for a small, programmable and self-contained
stepper controller. At least for my personal use :-)

My design is modular, so I will make sure to develop a microstepping
option next !

Thank you for your feedback,

bruno

PS: the rings you make are really cool.
