i decided to get here for the advise after many hours of frustration and half spool of PLA wasted.
Usually i print mainly ABS and ASA and don't complain from the results, but this time
First some basic information.
My main machine and the one i try to use for this project is modified self-constructed HEVO based printer. Linear rails for movement with 20x20 extrusion to support X;
Hemera extruder with titanium heat-brake, copper heat block, PT1000 and 0.5mm "nozzel X";
300x300 MK3 Chinese knock-off aluminum heat-bed (not perfectly flat i know) with BuildTak FlexPlate system on top and BuldTak original sheet on the flex plate.
Duet3 6CH MB (standalone) with IR sensor for bed leveling.
Material used for the project:
FormFutura white rPLA
3D Model i try to print:
Setting tried so far:
40 to 75 deg C for heat bed
190-215 deg on nozzle
from so close to bed that it leaves a permanent mark on BuildTak to so far that get almost perfect circle on initial layer lines.
Glued "painters tape" on second plate and used all of the above settings again.
Finally - upgraded from RRFW 3.2.2 to 3.3
all of this leads only to peeling edges and on 10-ish millimeters form build plate i stop the print as it is so badly pealed that start hitting IR probe. (forgot to mention that on one of the experiment i used brim)
Any ideas what to do in order to get this cursed PLA to stick would be highly appreciated.
I apologize for this long post, but i am really frustrated
