Hi all. This is a Y axis on an Ender 3 v2 with dual Y rails.
Which frequency and shaper would you say is better? I'm not sure the recommended ei is correct. Happy for your input.

To determine the best frequency and shaper settings for your Ender 3 v2 with dual Y rails, it is important to understand what these settings do. The frequency setting controls the speed at which the printer's stepper motor moves, while the shaper setting controls the shape of the power signal that controls the movement of the motor.

For the Ender 3 v2, the recommended frequency is usually between 25 kHz and 35 kHz, with 25 kHz being the default setting. As for the shaper, the default setting is usually "Trinamic SpreadCycle." However, different shaper modes may work better for different applications, so it's worth experimenting with your printer to find the best combination that works for your specific needs.

Ultimately, the best frequency and shaper for your printer will depend on a variety of factors, such as the type of filament you are using, the complexity of your prints, and the desired speed and accuracy of your prints. I would recommend starting with the default settings, ...

you dont really wanna go anything other than the recommended shaper rn

#

because everyone says MZV and I'm confused

graceful ruin
#

i mean you can

#

itll just mean u have ringing

#

your best bet is trying to find out whats causing the extra frequency at 100hz and 60 ish hz

#

mzv literally does nothing here for you

#

as you will have less max accel and more remaining vibrations

this is the stealthburner toolheadon the X axis with orbiter v2 and orbiter sensor, phaetus dragon. it's quite a heavy toolhead.

have you ever watched this?

#

it helped me greatly in understanding what the graphs mean

#

and diagnosing issues

cloud pendant
#

I did. I also watched Nero3D video about it and I got more confused.

#

since this is an ender 3 and not core xy, I get different results

#

it's highly customized printer so it won't behave as expected

graceful ruin
#

yeah ofcourse

#

what bearings are you on

cloud pendant
graceful ruin
#

what bearings youre using in your printer

#

i wonder if they could be causing resonances on your x axis

cloud pendant
#

hmm... the stock bearings

#

with PTFE wheels

graceful ruin
#

oh what the f

#

idk how they do at higher accels tbh

cloud pendant
#

hmmm...

#

no idea 🙂
