How ideally calibrate new material

Hi All,

I try to use new material. I purchased ecoPLA 1.75 for me Elder3 V3 KE as for try calibrate new material. The technical specification said temp. 195-215C and density 1.24g/cm3. The rest of them need to determined by the calibration where I running to troubles.

I sensing the calibration menu point in Creality Print v4.3.8.6678 using the Material and the Parameter config which is also used by slice button. So I made few initial setting here.
New material created (funny you are not allowed change Brand name) and I reduced

  • Max volumetric speed: 15.00 mm3/s
  • Printing temp: 210C
  • Initial Printing temp: 200C
  • Final Printing temp: 195C
    And also created new parameter config with slower speed settings (cloned from normal profile)
  • Print speed: 200mm/s and all other below changed by the SW automatically
  • Printing temperatures matching the material data above.
  • Build plate Adhesion Type: brim I made this due I had problem with the Hyper-PLA material also when higher levels (the print head knock the material and broken down the entire test model).

I am running with print below with prior calibration the ensure about Z plate level.

  1. When I tried with the Temperature calibration between 220-190C with 5C steps printed out without any problem.

  2. OK go to the next step. The Flow rate Pass-1 test I was unable print out. Here is the picture I stopped when reach the -10 plate due totally broken frame. As you can see all those test unable print correctly the 1st layer. Meanwhile initial layer print speed 100mm/s and initial layer travel speed 37.5mm/s (if they really uses my ecoPLA settings selected above for the calibration)

  3. I also tried the Max flowrate calibration that is mostly printed out just the 20mm3/sec have not smooth wall so I used 15mm3/sec correctly as max flow rate :slight_smile:

  4. Pressure advance test not possible due with autobrim settings the small circle brim around corners not enough stable to my complete printing move away from the pad :frowning:

Anybody could have good practice how to board new slower materials in this relative high speed printer? Any better approach or idea?

Maybe this might help?
