Stringing after ALL known fixes applied
Hey all
OK so a little back ground.
8 years in 3d printing!
I build a D-bit that i am using Repetier on. I use repetier on another printer for almost 2 years. SO I LIKE IT!!
I am experiencing stringing - it is light as spider web but still there!
BEFORE i go further IS the ANYTHING in the firmware i can change or try??

Ok, so; now officially the only thing I haven't tried is changing boards or drivers or voltage of the drivers or changing any wiring etc.
Regardless of anything the stringing is EXACTLY the same. Like fine spider web..
I am stumped
Ok I have posted this in other groups.
In short this is what I have done:
1. Adjusted retraction between 1mm @ 15mms to 30mm @ 350mms
2. Adjusted temps from 220 down to zero extrusion temp
3. Changed stepper motors
4. Changed bowden tube
5. Changed nozzle sizes
6. Adjusted filament size
7. Adjusted extrusion rate
8. Adjusted move speeds
9. Changed the bowden couplers
10. Changed heat break throat
11. Changed heating element
12. Changed heatbreak fan positions
13. Changed filament types and colours
14. Designed a different stepper mount closer to the carriage and shortened the bowden tube from 400mm to 250mm
15. Changed the extruder itself
16. Adjusted firmware settings
17. Changed e3d hotend to chimera
18. different layer fans
18. different layer fans
The results have proven that the silk strings are consistently the same. Which is good BUT there is still stringing.
Oh I have even used a fine file to smooth the nozzle tip and I still get a spider web. Literally as fine as spider silk.
What are your EXTRUDER acceleration and jerk settings? Not sure if that would affect it.
BUT we are never too old to learn and maybe someone has experienced this. I.e. literally done EVERYTHING And then figures it out...
Tnx

I am also wondering if number of steps that the drivers are set to makes a difference. i.e. 1/16 or 1/32 or half step or full step etc... not sure for the extrude what is nest - i never thought about it before.
so all i haven't tried is jumpers and steps and a new board.
