Re: New Smoothie Board
I can try give it a shot at routing if you'd like the collaboration, better said if you want me to mess with it, but just for me soonest break is probably to end of next week.

Feel free! I'll probably keep fiddling with it this weekend, but I haven't come up with a layout that I'm totally thrilled with yet. Plus, with this being only the second board I've ever laid out, I'd...

I sorted the schematic a little, redone annotation, and made a pull request for these changes.

QuoteYou could try the shift register idea to expand IO, but I would be worried about timing/delays/speed depending on what you are mapping through the expanded IO. Just the Step signal is very time...

Oh. I really missed that. Thanks. I am also taking this chance to reinvent the wheel - as a professional programmer, I am not happy with the architecture and design of the Marlin firmware I have been...
View ArticleWhat drivers to use with 42BYGHW811 Steppers motors
Hi everyone I have 42BYGHW811 Steppers motors and and RAMPS 1.4 spec for motors is: 2.5 Amp and 3.1V what stepper drivers I should use. I have 5 EasyDriver Boards but I don't see how I can use them...

Merged. Thanks NoobMan. I've also added two issues with the power side of things.
View ArticleRe: What drivers to use with 42BYGHW811 Steppers motors
Max current is the only thing that matter. "Voltage" of the motor is that the current you will get when you apply that voltage blindly - which doesn't matter when we are using drivers like polulu...

hi, nice driver, i was exactly looking fo something like this... cause i find the stepstick drivers too expensive when you know they can hardly drive 2amp. it seems that the l297/l298 was used for 1.0...
View ArticleRe: Why only stepstick and pololu stepper driver?
We only need about 1A and without micro stepping reprap machines are very noisy. I don't know if there are an cheaper microstepping drivers than a stepstick.
View ArticleRe: Why only stepstick and pololu stepper driver?
TB6560 has a much big footprint, not SMD friendly, yet it can only drive 3A. When you need more than 2.5A that A3977 suoports, most likely you need a much bigger one instead of #A. TB6560 also need a...

L297/298 has no microstepping, and much much bigger footprint and needs even more passive component, not SMD friendly.
View ArticleRe: Why only stepstick and pololu stepper driver?
I think the biggest reason is resolution. Without microstepping you are looking at 5 to 10 steps per mm in X and Y which is just barely adequate. With microstepping the picture is much better. Add in...
