LeeOtts / Ender3v2-Klipper-Configs

Welcome to the repository that houses meticulously crafted configuration files for a modified Ender 3 V2 printer, complete with the Sprite Pro Extruder, CR Touch, and a 4.2.7 silent board. These configuration files are specifically designed to empower you with unrivaled control and precision. Due to popular demand I recently added a 4.2.2 config.

Gear Ratio Incorrect #10

Closed TapticDigital closed 5 months ago

TapticDigital commented 7 months ago

Sprite Extruder Pro has a gear ratio of 3.5:1

LeeOtts commented 6 months ago

What makes you say that? Can you link your sources?

I am asking because the S1 profile on Klipper docs has the same extruder gear ratio I used.

Sure, it says it a few times on Creality's official Sprite Pro page and documentation.

Thank you for that information.

Hmm, this is going to require testing. I see a lot of other printer configs that have the same ratio I am using. I guess they got it from the same source.

Have you tried changing it? How did it work out?

TapticDigital commented 6 months ago

I changed it in my klipper settings and noticed marginally better extrusion steps/accuracy, though I suspect it doesn't make a huge difference

Ok cool. Can't wait to give it a try. Thank you for bringing this to my attention. On Dec 23, 2023 1:57 PM, TapticDigital @.***> wrote: I changed it in my klipper settings and noticed marginally better extrusion

How did you overcome the gear ratio must use 2 units when using 3?

gear_ratio_error

TapticDigital commented 6 months ago

I wasn’t aware there was a 2 digit limit? This is my extruder code: `[extruder] max_extrude_only_distance: 1000.0

step_pin: PB4

dir_pin: PB3

enable_pin: !PC3

microsteps: 16

gear_ratio: 3.5:1

rotation_distance: 7.531

nozzle_diameter: 0.400

filament_diameter: 1.750

heater_pin: PA1

…`

so far I haven’t had it give any errors. I’ve also tried just leaving the gear_ratio out entirely and saw no difference.

LeeOtts commented 6 months ago

Oof, I feel like an idiot. I was doing 3.5.1, not 3.5:1.

TapticDigital commented 6 months ago

No worries, full disclosure I know maybe 2% about Klipper, I just noticed an inconsistency when I was trying to figure it out. I am far from knowledgeable about any of this.

LeeOtts commented 5 months ago

I definitely had to do some tweaking, but I got the gear ratio corrected to align with Creality specs. Thank you for bringing this to my attention.
