v-minion rattling noise

I just realize watching other people’s videos that my v-minion makes an awful amount of noise, especially a rattling one when homing or mesh calibrating. This is a stock full kit, it’s greased with NLGI-2 lithium grease, there seems not to be any loose screws on the eva (pressed them to test), prints are good so it seems well calibrated… I didn’t use any alignment jig but rails seem to be decently aligned. Oh and I’ve enabled the performance steppers settings. What is going on?

print faster every stepper profile has a goldi lock zone where it isnbt so loud depending on the profile you choosed you need to find this zone jsut try to print a bit faster

I'm printing at 200mm/s, except first layer on PLA which is set lower -- but the problem I'm seeing is the noise when homing & mesh-leveling

Helge Keck•2y ago

change the homeing speed then

I'm nowhere near the smoothness I see in this video https://www.youtube.com/watch?v=RQMcs3vpjSo

had no idea you could change the homing speed... will try, thx @Helge Keck 🙇‍♂️

Helge Keck•2y ago

[bed_mesh]
speed: 300

[z_tilt]
speed: 300

[printer]
max_z_velocity: 35

play with these values

ratty-blushOP•2y ago

as we're on it, what speed are you printing PLA?

Helge Keck•2y ago

i dont print PLA

ratty-blushOP•2y ago

PETG? I'm asking max speed here

Helge Keck•2y ago

500mm/s

ratty-blushOP•2y ago

holy guacamole

Helge Keck•2y ago

up to with the minon you can print that fast

ratty-blushOP•2y ago

okay, I'll try to increase all speeds (by order of magnitude, I see)

Helge Keck•2y ago

dont try this at first try you need to do this step by step

ratty-blushOP•2y ago

config by config, or you mean increase each speed incrementally?

Helge Keck•2y ago

you need also a cooling solution that can handle these speeds and the extruder, hotend, .....

ratty-blushOP•2y ago

it's the stock LGX Lite + BMO setup

Helge Keck•2y ago

ok, then you cant print that fast

ratty-blushOP•2y ago

(I know, you're big fan of Orbiter 2.0 + Rapido, just give me time)

Helge Keck•2y ago

no problem, start slowly, the speed comes by its own

ratty-blushOP•2y ago

I think I've printed at 300mm/s nicely alright, after quite some testing I've boiled it down to

max_z_velocity: 20

[bed_mesh]
speed: 300
probe_count: 5, 3

[probe]
speed: 20
lift_speed: 20.0
sample_retract_dist: 1

[stepper_x]
homing_speed: 80
second_homing_speed: 80
homing_retract_dist: 5

[stepper_y]
homing_speed: 80
second_homing_speed: 80
homing_retract_dist: 5

[gcode_macro RatOS]
variable_macro_z_speed: 20

max_z_velocity: 20

[bed_mesh]
speed: 300
probe_count: 5, 3

[probe]
speed: 20
lift_speed: 20.0
sample_retract_dist: 1

[stepper_x]

second_homing_speed: 80

[stepper_y]

second_homing_speed: 80

quite an improvement in noise and speed also, the 5015 blower fan is the source of rattling -- can't wait to get my delta 4028 I ordered to RR I did put some masking tape on the joint with the duct but still
