[SOLVED] Extruder temperature decrease after the first layer  

Re: Extruder temperature decrease after the first layer

Hi, what Slic3r you use? Does it work with the default settings from the driver package?

Re: Extruder temperature decrease after the first layer

Thanks for your answer.

I'm using slic3r 1.2.9 with the official settings downloaded from the site.

Re: Extruder temperature decrease after the first layer

In the pictures attache you can see that I try to increase the temperature from the lcd from 215 to 220 but it still at 190

Re: Extruder temperature decrease after the first layer

I try again to insert the configuration bundle in slic3r , printing a 15*15*1 mm square with normal pla setting. After the first layer at 210 the temperature decrease at 206 the second layer and at 202 the other.

Nobody can help me?

Re: Extruder temperature decrease after the first layer

Preheat the ozzle for the temps you want, then try turning on the fan from LCD menu at 210 and let me know if the temp will go down.

Re: Extruder temperature decrease after the first layer

Ok, as soon I will back home I will try.

THANKS,
Massimo.

Re: Extruder temperature decrease after the first layer

Hi Josef,
preheated at pla temperature and turn on the fan from lcd: temperature is fixed to 210. Is a good things or not?

Re: Extruder temperature decrease after the first layer

I've tried to reduce the fan speed during the print and the temperature is more stable but I have to change it every layer, no way to solve this?

Re: Extruder temperature decrease after the first layer

Can you post a screenshot of the slicer filament settings you use?
Also check if the hotend power connector is properly secured in the motherboard and the cables are properly screwed inside the connector housing.

Re: Extruder temperature decrease after the first layer

Good morning Josef,
attached the printer settings as you ask me.
They are the default from last 1.6 package.

Bye,
Massimo.

Re: Extruder temperature decrease after the first layer

Problem solved by myself.

Thanks.

Re: Extruder temperature decrease after the first layer

Can I ask for the cause of the problem? In case someone else had the same issue?

Re: Extruder temperature decrease after the first layer

I don't know the cause of the problem, I've asked you for it. Till the cause comes out I've solved removing from slicer filament settings the flag on "keep fan always on" and reducing the min & man fan speed at 50% & 75%. This way the temperature goes from 220 to 210 so is perfect for me.
I hope someone find the origin of the problem.

Massimo.

Re: Extruder temperature decrease after the first layer

Can you check if the blower fan duct isnt damaged? If its broken it could direct airflow directly at the heater block.

Re: Extruder temperature decrease after the first layer

Thanks Josef for your reply. I've checked the blower fan duct and it's ok. I understand what you mean but ... isn't it the cause of the problem.

Re: Extruder temperature decrease after the first layer

I have noticed similar problem today, but only on certain circumstances. I am doing some tests now.

Re: Extruder temperature decrease after the first layer

Thanks a lot Josef, I look forward to receive your notice.

Bye,
Massimo.

Not Josef here 😀
