Hello All!!!

I am giving a CUBE print 20x20x10mm at PLA 205 degrees but model is been printing at 207 degrees and then decreasing to 205 degrees normally...

Any one can help me ...?

Sounds to me that you've got your first layer settings set to a higher temp check your slicer.


Out of the box thinking is easier when you never fitted in the box to begin with. smiling smiley

Hi again!!!

I run the commands M303 S200 C5 and

Kp: 28.22
Ki: 2.25
Kd: 88.31

But whats the value for PID-C...? C for CYCLES...? That is 5...?

Ok thanks for replying. I have done by command

M303 E0 S205 C3

Got AUTOTUNE value and uploaded.

But also getting as 208 degrees... Model is given at 205 from CURA...

Its going upto 208 and then little extruding at HOMING and then reducing at 205 then starts to print....

Please help...

Thanks for all supports...

All right instead of CLASSIC, I wanted to use NO Over shooting...

Here are the my values...

M303 E0 S205 C3

For 205 Degrees... Values are KP=27.61 KI=2.08 KD=91.83 C=3

Please tell how can avoid over shooting.....That is I wanted exactly 205 degrees... It should not go beyond that.... Like depending on Model temperature is should take exactly... It might be 205 or 208 etc...

Please help me....

OK I have calculated the NO OVERSHOOT VALUES as

Kp=Kp_classic/3
Ki=Ki_classic
Kd=Kd_classic*8/3

Values are KP=27.61 KI=2.08 KD=91.83 C=3

New values are 9.20, 208 and 91.83....But still 205 Degree model is going upto 208 degrees and ruining the model....Please the model....

far too much worry of temp variations especially if you have a parts cooling fan and those few degrees won't affect print
