Ender 3 automatically prints at the wrong temperature

[minor cove]

When I pre-heat PLA it goes to 200C and on cura it’s set to 200. But when the print starts it sets at 175. Also, my first layer on my print randomly has shit pop off the build plate am I have no idea why.

It sounds like you might be experiencing some issues with your print settings and adhesion. Here are a few things you could try to troubleshoot the problems:

1. Check your temperature settings: Ensure that your printer's temperature settings match those in your slicing software (Cura). Check if there are any specific temperature changes or overrides in the slicing settings that might be causing the difference in temperature during the print.

2. Clean and level your build plate: Make sure your build plate is clean and free from any residue or oils. Additionally, ensure that the build plate is properly leveled to ensure good adhesion. Leveling the bed ensures that the nozzle is the right distance away from the bed, helping the filament stick properly.

3. Use a suitable adhesive or build surface: If your prints are still not sticking well, you can use different adhesives such as hairspray, glue stick, or specialized 3D printing adhesives like a build plate tape or a PEI sheet. Alter...

That isn’t helpful

[empty osprey]

Have you made any firmware changes to your printer?

@minor cove

[minor cove]

Nope

[empty osprey]

Post your start gcode

[dry rover]

Why? Its one of the better AI answers here. These points are standard procedure for your problems, did you check those and the problem still persists?

[minor cove]

I don’t know where to find it

[minor cove]

Yes

And I’ve stated that in the post

[dry rover]

Okay then the gcode like clay said

Second line?

Oh yeah nvm

@empty osprey

Reading

[minor cove]

Also

I set my z steps a while back but I changed computers but didn't transfer over profiles

But I think I also messed with an extrusion multiplier

[minor cove]

On the old profile

[minor cove]

Can I make it so both heat at once?

[empty osprey]

You got this printer new right? No chance of any firmware changes that you wouldn't know about?

[minor cove]

Yup, straight from creality

A long time ago I changed the zsteps to like 100

[empty osprey]

I don't see how that would affect the temperatures of the printer

Do you have a computer you can plug into the micro USB and use pronterface?

[minor cove]

I don't either

and it happened a long time ago

[minor cove]

Not anymore

[empty osprey]

Go into Cura, look up the setting "printing temperature initial layer"

[empty osprey]

Wow

Can I send you a Gcode of a calibration cube? You put it in your printer and see if it does the same thing?

[minor cove]

Sure

I gotta go down the stairs in rollerblades tho so I mgiht need a bit

[empty osprey]

I commented out G29 so it wont try to use the probe

[minor cove]

What?

Yup, 175

@empty osprey

And it’s peeling up

This is upsetting

[empty osprey]

Thats super strange. Id recommend you try resetting your printer to factory settings

Cause that rules out the gcode

[minor cove]

But my esteps

[dry rover]

I bet its the material_standby_temperature, try commenting that line out (add # in front of it), slice a print and see if it's heating up at all. My guess is that the definition material_print_temperature_layer_0 does not get recognized and skipped.

[minor cove]

Busy rn sorry

[dry rover]

No problem

I read the gcode, I noticed preheating temp is set as a whole number and printing temp has a decimal point. No idea why, and it shouldn't matter but modify the file so both are whole numbers.

ok

Whats happening?

[dry rover]

I answered the question of @empty osprey

[minor cove]

Do you know why the prints un stick?

[dry rover]

https://www.simplify3d.com/resources/print-quality-troubleshooting/not-sticking-to-the-bed/

Also did you do the suggested change in the gcode?

[dry rover]

This suggestion?

[empty osprey]

Hello

Prints unstick due to poor bed adhesion, this can be caused by quite a few things, most commonly improper nozzle height and unclean print bed.

I recommend you use the paper method to level your bed,

if you have touched your bare hands on the bed, you should wash it with soap and hot water as the oil from your skin can cause adhesion issues

Did you have any luck with your temperature starting too low?

[minor cove]

Not yet. I am extremely sick rn

[empty osprey]

Wishing you a speedy recovery

[dry rover]

Get well soon!

[minor cove]

My recovery was very speedy but I still don’t feel 100%

Thank you all
