Ender 3V2 Print Problem after Mriscoc Firmware Update

[errant ravine]

Hello I need your help. I have installed the new firmware from Mriscoc on my ender 3v2.

https://youtu.be/pxBGBjLC2rk?feature=shared

Now I wanted to start my first print with the new version. Now to the problem. The printer makes the first purge line on the left and then moves to the middle to start printing. It prints 1 second and starts up and, according to the display, makes an "Advanced Pause". Then it goes all the way to the right of the print bed and starts to extrude about 5mm of filament. 5 seconds later, the extruder pulls back almost 10 centimeters of filament. The device starts beeping. I should press "continue". then he extrudes the filament very slowly until after 15 seconds filament comes out of the nozzle again. he stops. the display shows "purge" or "continue". with "purge" it continues to extrude filament. with "continue" he continues with the printing. it prints 5 seconds and the whole thing repeats itself from the beginning. Anyone know what's going on? It's not the Gcode file. I have already tried old gcode files. he does it every time.

AI Help

It seems like you are experiencing some issues with your Ender 3v2 after installing the new firmware. Here are a few troubleshooting steps you can try:

1. Check your G-code file: Even though you mentioned that you have tried different G-code files, double-check to ensure they are sliced correctly and compatible with your printer model.

2. Reset to default firmware settings: If you made any custom changes or modifications to the firmware settings, try reverting back to the default settings and see if the issue persists.

3. Check for compatibility issues: Verify that the firmware version you installed is specifically designed for your Ender 3v2 model. Using incompatible firmware can lead to unexpected behavior.

4. Check the extruder and hotend: Make sure there are no clogs or obstructions in the extruder or hotend assembly. Try manually pushing filament through and observing if it flows smoothly.

5. Calibrate the extruder steps/mm: Incorrect extruder steps/mm settings can cause f...

you need to set the bed parameters, also you may have to do an esteps calibration again (mine defaulted to 93) there's instructions on doing that on the mriscoc firmware page. also in cura (or what ever slicer) change the purge line x location from 1 to 6.

[errant ravine]

Thank you for the answer. My esteps are already on 93. I would like see the instructions. But i cant find them on his github:(

[upbeat fox]

yes, 93 is default, you need to calculate esteps

[errant ravine]

My Problem is, why does he starts printing and stop after 1 second and does weird things? Exactly like in my video

I did a calibration like in the github post

[upbeat fox]

I suspect something in your gcode

because that's not standard behavior

[errant ravine]

Can i reset the printer?

To have the Standard settings from new firmware

[upbeat fox]

you could but you would want to ensure you have the correct settings saved somewhere as some stuff isn't going to change

like your offsets

[errant ravine]

i found out that he prints the skirt line quite normally. only when he wants to start the actual printing does he make this pause, which is repeated over and over again.

[upbeat fox]

you would look at your gcode for that

you might have some "pause at x" macro running

[errant ravine]

Is the gcode in my slicer? I have never done it before

[upbeat fox]

yes

it saves the gcode

which slicer?

[errant ravine]

Cura

But i have a lot of old print files on my SD Card. He does this even on the old files

And before firmware update i printed them all

[upbeat fox]

Old files have different gcode for your old firmware

Using the new firmware on a freshly sliced model

[errant ravine]

So what should i change in my cura slicer?

[errant ravine]

This is my gcode

[upbeat fox]

https://github.com/mriscoc/Ender3V2S1/wiki/Slicer-G-code-Scripts

though i would change these lines

G1 X0.1 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line
G1 X0.4 Y200.0 Z0.3 F5000.0 ; Move to side a little
G1 X0.4 Y20 Z0.3 F1500.0 E30 ; Draw the second line

to this

G1 X5.1 Y20 Z0.3 F5000.0 ; Move to start position
G1 X5.1 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line
G1 X5.4 Y200.0 Z0.3 F5000.0 ; Move to side a little
G1 X5.4 Y20 Z0.3 F1500.0 E30 ; Draw the second line

under extensions, post processing scripts do you have anything? I currently have this

which if i go to slice something it will do something

can you attach one of your gcode files?

[errant ravine]

@upbeat fox

[upbeat fox]

Try removing those two scripts and slicing something new (and small like a calicat or flow cube)

[errant ravine]

i removed the scripts. now i will try this gcode

I am frustrated... @upbeat fox

[upbeat fox]

did you make the changes to the start script I suggested?

weird that you're getting a pause after

[errant ravine]

Yes i made. But this time there was no filament, because the extruder pulled it back before i started the print

The Pause is weird

I dont know why he does it

[upbeat fox]

do you have a filament sensor?

[errant ravine]

Nope

[upbeat fox]

check the settings for filament sensor in the menus

[errant ravine]

Its a stock printer

I disabled runout

Maybe i will help

[upbeat fox]

the firmware has functionality for it and if it's set to on it may let you print ab it

and then pause

so it's off in that pic

[errant ravine]

I disabled it before i made the pic

[upbeat fox]

ok that was probably your problem try again

[errant ravine]

Damn

It was the runout button

[upbeat fox]

👍

[errant ravine]

Shit printer

[upbeat fox]

since it is stock I recomend a couple upgrades, a full metal (non creality) hot end, a full metal extruder, and for quality of life a cr touch

[errant ravine]

I installed a new metal extruder yesterday:)

[upbeat fox]

is it the creality one?

[errant ravine]

No a 4€ aliexpress one

[upbeat fox]

so you will need to replace the gear at some point because it wears fast, it's brass

[errant ravine]

It was a extruder kit with new gear

[upbeat fox]

I replaced my extruder with the dual gear one, but you need the double washer on the second gear version

yeah it's a clone of the creality one, probably same factory, it has a shitty gear made of brass

the brass gear will wear fast.

[errant ravine]

Oh okay i will check it

[upbeat fox]

for the hot end there's a few quality ones, you want all metal, not ptfe lined. you can also possibly buy a bimetal heat break for your current hotend

[upbeat fox]

.de?

[errant ravine]

German yes

[upbeat fox]

I'll show you the one I got from amazon, the important part is it needs 2 washers to prevent it from wearing too fast

https://www.amazon.ca/gp/product/B09H6T3NNT/

german amazon has them too https://www.amazon.de/gp/product/B09H6T3NNT/

so similar design but you wat the one with the washers as shown in the first pictures, should be on aliexpress. no hurry, you probably have a couple months or so before the one you have starts to slip

[errant ravine]

thank you. i will buy it, when my extruder starts to work bad

[errant ravine]

Wow. New firmware, new problems😂

[upbeat fox]

basically all the settings have been reset and aren't the same you had before

so you need to tune it appropriately

[upbeat fox]

Also since you changed extruder from stock the esteps needed to be done
