hii thank you ! you forget the E steps. DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 424.9}

@naty6458 -- where did I forget the E-steps?

@naty6458 were you able to get this firmware working with your printer?

naty6458 commented 11 months ago

I used CONFIG of Ender-3/CrealityV427. Marlin V1.2.1.2.

The compiler made an error about the temperature. I returned back to 275.

Later I will prepare a GCODE and try to change the value of MAX TEMP.

The settings ROTATE_PROGRESS_DISPLAY, LCD_SET_PROGRESS_MANUALLY, USE_M73_REMAINING_TIME were probably not found in Marlin V1.2.1.2

I have been having the same issue with the temperature the temp sensor type need to be changed

Thanks!

Hello, I am using your Marlin firmware, I also have the Ender 3 Pro with Sprite Extruder and 4.2.7 board. However, there is a problem that has already cost me a few heating blocks. Without me doing anything, the extruder feeds filament at regular intervals (hotend heated). As a result, I have already had a lump of filament on the hotend twice during a night print that I could not remove without damaging the cable of the temperature sensor.

Is this something that can be set in the firmware?

Greetings and thanks Christoph

Christoph-

In Configuration_adv.h, there is a setting that controls this behavior:

`// Extruder runout prevention. // If the machine is idle and the temperature over MINTEMP // then extrude some filament every couple of SECONDS.

define EXTRUDER_RUNOUT_PREVENT

if ENABLED(EXTRUDER_RUNOUT_PREVENT)

define EXTRUDER_RUNOUT_MINTEMP 195

define EXTRUDER_RUNOUT_SECONDS 30

define EXTRUDER_RUNOUT_SPEED 1500 // (mm/min)

define EXTRUDER_RUNOUT_EXTRUDE 5 // (mm)

endif`

Comment it out and recompile the firmware.

Hey Everyone:

I commented out EXTRUDER_RUNOUT_PREVENT and recompiled. You can download it here: https://cdn.tinycomputers.io/creality-ender-3-pro/firmware-20240423-170646.bin

christophjodexnus commented 2 months ago

thank you :)

whats the function of this?

ajokela commented 2 months ago

thank you :)

It supposed to be a feature that helps prevent filament burning in the nozzle by keeping melted filament moving. But, I too have run into the same issue you were seeing with filament build-up on the nozzle.

naty6458 commented 2 months ago

I have the same problem... (if it matters I usually use PETG). I think it's something physical and not software. Just now I broke the thermostat due to a failed cleaning. I ordered a slightly different heating element. I will update what the result is.

https://www.aliexpress.com/item/1005006120501974.html?spm=a2g0o.order_list.order_list_main.15.6d8d1802biDFEF

In addition to that I found just now , this discussion online, they say it is a factory defect and that there is a crack in the tube of the heating block.

https://www.reddit.com/r/Ender3S1/comments/z19f6s/ender_3_s1_pro_leaking_from_top_of_heating_element/

I also checked what the default ENDER S1 settings are in FW.

This reinforces the assessment that it is hardware and not software.

ajokela commented 2 months ago

I must have misunderstood the description of the problem. If melted filament is coming out of the top, it is definitely not related to EXTRUDER_RUNOUT_PREVENT
