Jerky movement during solid fill / perimeter.

[Mehmet Özbek]

Thank you for accepting me into the group.

I have a Flashforge Advanturer 3 printer.I was using Flashprint software, but after seeing ICESL 2.3.5 Beta2 , I don't use it anymore.
The surface quality of ICESL complex parts is quite good. But I'm having problems with circular slices like the attached piece.
My main problem is Jerky movement during solid fill / perimeter.
Can you help me with which settings should I play with?
Attached files:

3D model: PROBLEM.stl
Flashforge Advanturer 3.zip : My printer profile.
PROBLEM1.jpg : Result printed.

PROBLEM2.jpg : Gap header.dat: Unfortunately, the Flashforge gx format is a little different. I have to put this binary file at the beginning of the gcode..Otherwise the printer does not work. If you want, we can look at this together.

ICESL_GCODE.gcode: ICESL original g-code for Advanturer3/4
ICESL_GCODE_ADD HEADER.gx: Added binary header.dat at the start of gcode.
1- My first question is, is there a Flash forge Advanturer 3 profile?   There may also be a problem with my printer profile.

2- How can I get rid of jerky movement during solid fill / perimeter ?PROBLEM1.jpg

3- I can't fill in the gaps between the sphere and the cone.PROBLEM2.jpg Thanks,

Hi Mehmet. Allow me to answer your questions.

Unfortunately, we don't have a profil for this specific printer. You can submit it via merge request in our printer profiles github and we'll see if it's apt for inclusion in the official relese of IceSL!

GitHub - shapeforge/icesl-printers: Printer scripts and profiles for IceSL

The gaps you're having is a known problem of the way IceSL calculates covers, we are actively searching the best way to prevent this. In the meanwhile, you can avoid this issue by adding more shells to the whole print or just in a small section via per-layer specification (see the screenshot below):

Finally, regarding the noisy surface due to what you describe 'jerky movement', we could not reproduce it. We printed a couple times the stl and found the surfaces to be appropriate. However, we used a different printer as we don't have your specific  model. We can give you some tips that can ameliorate the situation; (a) deformations can occur because the plastic doesn't have enough time to cool down, try using a temperature of 190 degrees, (b) if you can/desire, print the model twice so the printer layers have more time to cool down, (c) reduce layer height. This will increase quality but also print time and lastly, (d) leave the door open on your printer when you're printing with PLA.

Hope this helps!

Hi,

Thank you, I will follow your suggestions for PLA. When the process tolerances were reduced, jerky movements disappeared.

Ask another question about variable perimeter and infill feed rates. 

Is there a variable to calculate the perimeter of each section on the same layer that I can use in print.lua?
I want to set a feed rate with a limit condition for both perimeter and infill.

For example; There are two sections on the same layer. If the perimeter is less than 25 mm, reduce the feed by 50%, (F1800)  otherwise, use the perimeter feed rate (F3600) for both perimeter and infill.

I think I can explain it better in the attached picture. 

Mehmet
