Re: Stepper motor for my project (ACT motor GmbH 17HS5412-3)
They will both work fine, but I'd tend to the 1.68A version and run it with 1.3A max. How to adjust Vref of your A4988 model ( there are different shunt resistors ) is described here.

Thank you for your input. :-) Could you possibly clarify why you would choose 17HS19-1684S1. As I understand it, one should preferably choose a stepper motor with a low corrent, otherwise the motor...

An analougy would be: I can drive slow in a slow and a fast car, but I can only drive fast in a fast car. So the stepper with the higher current rating will behave almost equally at low current and I...

Problem1: The white screen could be wrong contrast adjustment. Do you see a potmeter on the back of the LCD? Problem 2: You have to switch two wires of the steppers that hums / vibrates. Either switch...

I've noticed the TMC2100 create some resonance noise at certain speeds. Maybe you are running the z-stepper with such "bad" speed?
View ArticleRe: TMC2100 (SilentStepStick) for Mightyboard?
I have yet to print anything so I am not really sure how it will sound. I am testing by jogging the z axis up and down and comparing this to x and y axis. It will be loud on certain steps but quiet on...
View ArticleRe: TMC2100 (SilentStepStick) for Mightyboard?
There is also a huge noise difference between 12V and 24V. But that'd be the same for all steppers. I ran the drivers in stealthmode on my Prusa i3 a while and it worked quite well. But I had to crank...

Sounds like a bad solder or cracked trace on the driver. If you don't see anything you could fix with a solder iron or heatgun, just replace it.
View ArticleRe: TMC2100 (SilentStepStick) for Mightyboard?
Thanks. The board is using 24v power supply. I assumed the drivers are fed 24v but I have yet to check. FFCP is using a Mightyboard RevE. I will need to do some tinkering to figure this out.

View ArticleRe: MKS LV8729 , a 128 µStep Driver // Any test?
The vref at 0.4v gives 0.8A so you're running those motors at/near their maximum current handling, they will always be noisy when near that level. The document above has values of vref against...
