Hi,
i got 3 smaller issues with my printer config. I have to say that i already turned 2 of my printers into klipper machines and am very pleased with them, unfortunatelly it seems i still need a lot to learn.
Last weekend i modified by FLSUN QQ-S Pro into a klipper machine, but i ran into 4 issues i wasn’t able to figure out myself what excatly is the problem. As it’s my first delta i was sure to have different issue to solve, but the most seems more strange commonly as to be a delta issue.
- I got issues with extrusion volume. I get exactly 100.00mm extruded with G1 E100, but it seems not to fit into prints. If i print something with 2 walls it’s set to 0,4mm and should be 0,8mm in total, but instead it’s only around 0,6-0,65mm if i raise the flow to ~125% it’s fine. But i don’t understand this as all 3 filaments are pretty close and consistand to 1.75mm (~1.739mm on ABS / ~1.738mm PLA / ~1.739 on PETG - average measured on 3 meters of filament) all from Extrudr. As i am at the beginning with my config it has no PA, IS or something else activated. I tested the filaments on Cura 4.12 with my settings and on superslicer with stock QQ-S settings (only wall size has been modified to 0,4mm). Before someone asks i am using a SKR 1.4 Turbo with TMC2209 with a genuine E3D Titan extruder and the 0.9 small but powerful stepper that was included.

- My first try on Neopixels. I would say it’s working fine, it starting with the correct color. Change color once print starts to “white”, but it’s not changing back once print is finished.

The next thing is that i am struggling with the prime circle line i want to do. At Marlin there was G2 X Y with R. At Klipper it’s with I J and i don’t get it. As you can see in my Start GCode i did 2 straight lines as i was not able to make this functional. My attempts mostly produced a curved line that alway ended outside of the printable area and due to that an error occured.
I simply wanted a quater of a circle on the front of the bed anything else
please be so kind and take the time to explain, not just simple write down the answer. -
Once i add SET_GCODE_OFFSET Z_ADJUST=-0.07 MOVE=1 to my start gcode, it directly abort prints as it says move out of moveable area. Did i get something wrong ? i wanted to compensate the paper of the paper Z-Offset test as i did it preheated and i have exactly 0.07 bigger first layer. I did so on my Cartesians aswell and on my Voron 0.1 without any issues.
And i have an understanding issue. How can i set up acceleration and feedrate of my extruder, as the Titan is pretty noisy with klipper defaults !? And once i tuned pressure advanced do i set my retraction distance to ~0.75mm even for a bowden setup ? On my others i only have direct drives and used 1-1,5mm and kept it after PA tuning without any issues. And at least, does make skew correction any sense on a delta ?
Thanks and Regards,
BPM
