Geeetech

Hi,

Is this normal for a A30M? I have stringing Problems.

Any Ideas?

Black plastics is most problematic one.

Try my profile for A10M, propably you need to change build size and zero position .

For PEI sheet delete line from gcode setup
G1 X12 Y5 Z0 F300 ; stop leaking hotend
otherwise your PEI sheet will have burned hole at zero position.

Hi

Thank you for your answer.

Not really better now.

I will send pictures in a few minutes

Hello,

as just described unfortunately no improvements.
I have now used Cura, Slic3r and Simplify. Unfortunately the quality of the pictures has gotten worse again. The stringing is almost everywhere identical.

I have now checked several temperatures, several variations of the E-Steps, different filaments and different parameters.

Is there an update for the printer? Are there any settings on the firmware that I don't know?

Hi, You can view your retraction settings:
Reference range: retraction distance: 3-4;
retraction speed 30-40mm / s.

I have also tried to use the retraction values to make a change. Unfortunately I did not succeed in improving this.

What astonishes me...why are the E-Steps on the A30M configured to 407 at the factory? Otherwise the value was always around 430?

Are there maybe other parameters wrong?

Hi, Regarding esteps you can adjust as needed,

Then the retraction setting can be increased,
The retraction distance is set to 6,
Printing speed is slower: 30-60mm / s;
Black supplies are more sensitive to temperature,
You can try to lower the printing temperature by 5-10 °.

It could be other thing - it could be due bad fittings od loose PTFE tube.

I have read in many articles that "stringing" and print quality is a general problem of Geeetech printers.

I have also gone through almost all recommendations of the users. From filament to slicer to parameters.
Everything had a corresponding effect. But never what I expect from a printer in this price range.
To give you a small overview of my prints I have attached a picture.

@Jarda3d: I also use your Slic3r Profil. No Changes

I followed a calibration where I printed four 1cm cubes spaced 10mm, 20mm and 40mm apart. I started with a travel speed of 50mm/s and retraction of 0mm. I then printed them increasing the travel speed by 30mm, keeping the retraction at 0mm. Eventually got to 150mm/s and I think this maxed out the speed of the A30M. The stringing was greatly reduced. Then I reprinted increased the retraction in steps of 1mm. I ended up at 5mm retraction where there was no more improvement.
