Re: What are some ways to decrease stepper motor noise and vibration?
If there is a mod in the building can you delete please. It told me it could not post because it thought I was a bot so I accidently doubled posted.

Nema 17 motor's. 2 of the small ones, 1 of the larger 84oz.in on my x axis. Mega and Ramps at 1/32. I got my DRV8825's turned to 0.7v. My setup draws about 2.5a average (no heated bed). It's a DIY...
View ArticleRe: Looking for ways to smooth out the movement of my stepper motors.
My main concern is the reason behind why the motors will sputter very hard during starts and stops. As far as the harsh changes in drection I have turned down the acceleration and jerk to 750 and 2.5...

One trick to easily find which wires are pairs on a bipolar stepper is to spin the motor shaft. Then short two of the wires together with a jumper or something. Spin the motor shaft by hand again, if...

there are silent step sticks. 1/256 micro stepping (this is internal only, externally they are still 1/16 so work 8 bit controllers, but runs quiet) [www.filastruder.com] There is also RRD Silencioso...

Yes I am actually looking for some new drivers. I want the 1/128 Pololu's so right now I am shopping around for the right 32 bit controller to control them. What controller will dc 42 recommend? Is it...

The fact you are using lead screws ( on all axis?) is new to me. What kind of lead screw is it? It must be some special , otherwise you can't expect to print faster than 20mm/s or the like. My lead...
View ArticleRe: Looking for ways to smooth out the movement of my stepper motors.
There are fast lead screws available. Whether it makes sense to use them over belts is a different story.

What sort of guide rails/bearings are you using? Try posting some pictures/video.

That's interesting, I thought lead screws were the norm. I didn't start reading through the forum until after built it. Originally I was planning for a CNC then decided to go with a 3d printer. I also...

BTW I have been messing with the configuration and I turned my acceleration and jerk up some more to 1250 and 12.5 but I think I need to dial it back to +-1000 and 10 because I have some shifted lines...
View ArticleRe: Looking for ways to smooth out the movement of my stepper motors.
Regarding the slip at higher speed, what steps/mm do you have configured for that motor, and what speed are you trying to achieve? As your printer has leadscrews, it probably has a higher steps/mm...

I did not think to try increasing the voltage. Except for on my drivers which is set to .800v and .900v on X and Y. Right now I am at 12 volts and the max I can go to with my PSU is 19.5. My Ramps...

View ArticleRe: MKS LV8729 , a 128 µStep Driver // Any test?
I got some to try. I am using them on my X & y axis @ 16 step with RAMPS Observations so far: - Quiet, similar to TMC2100 - Run cooler than A4988 or TMC2100 for similar current - No problems at all
View ArticleRe: MKS LV8729 , a 128 µStep Driver // Any test?
I believe they are the same chip as used in the THB6128 stepper drivers, but with the thermal pad on the bottom of the package instead of the top.
