Strange habit with BRIM

Postby harrygeier » Thu Jan 11, 2018 9:32 pm

Hi,

i am new to ideamaker . I started witht small pulley , which i had printed with other slicers before.
When print it with a 15 lines brim , at the beginning it appears as if my printer stutters like hell. The more it goes inward..the smoother it runs.
Onceit goes to the model itself..it works beautiful .

I did a short analysis on the Gcode with NC-Edit and see there are EXTREMELY many EXTREMELY short lines generated.

Does anyone have a clue what may be wrong ?
I added the Gcode for reference

I use latest beta build..3.0.5.1438

On the surface, the G-Code looks good from what I viewed. I do not believe you need quite so many lines of brim though. 4-5 should do just fine.

It´s a relatively small Object, so fewer brim lines decreases adhesion ( it´s ABS ) and it should be to the decision of the user...how much brim he wants. I will make a screenshot later and add it here, so you can see, that it´s creating microscopic small lines at the outer circles.
Also the same model sliced in cura is much much smaller in count of gcode lines. The stuttering comes as the serial communication on 250.000 baud and octoprints speed cannot cope with so much lines....

I looked and compared , for 2 of the pulleys , cura goes up to 2nd layer at :

;TIME_ELAPSED:292.319628
;LAYER:1
M140 S80
M106 S28.3
G0 F3000 X90.904 Y60.867 Z0.4
;TYPE:WALL-INNER
G1 F1500 E95.18517
G1 F900 X91.355 Y60.91 E95.20069
G1 X91.887 Y60.997 E95.21916

that is less than 8% of the code with ideamaker..

Also see the screenshot of the Gcode analyser. There are many moves shorter than 0.01 mm

Please check your programming ..

Due to the shape of Brim is circle, ideaMaker has broken the circle lines to be lots of short segments. To reduce the quantity of segments, we need to carry out merging or smoothing for the circle lines.
We will add this operation in next version.
