Original Marlin calibration tool by Sineos. 8mm) allen key or similar through the top side of the hotend to push the obstruction out of the bottom. Unfortunately, when I used the calibration tool (pattern method) to calibrate the pressure advance, after generating the gcode and printing it, the nozzle simply scratched the printing plate. Slow your perimeters down. I have played with retraction lengths and wipes but I am still getting huge gaps at retraction locations. 5 F2100 ; Retract G0 X180. So we implemented the flow dynamic control to solve the problem, similar to the "Pressure advance" in Klipper or the "Linear advance" in Marlin, with some non-linear effect compensation added. I'd like to know how often you should run the flow calibration, lets say. 4 R2 print pressure advance or PA from Ellis's tuning guide - YouTube.

Tried both following the Klipper instructions and installed and installed/used the plugin that allows tuning tower. Try adjusting your filament tension screw/thumbscrew (if equipped). Find the line that stays most uniform at the speed changes marked by the top two vertical lines. The first layer can look a bit overextruded partly because it uses your starting PA (often 0). I would expect a higher degree of variation or is there maybe something completely wrong in my setup? The Klipper tuning guide suggests how to tune pressure_advance parameter. With a high acceleration and high pressure advance the extruder may not have enough torque to push the required filament. 050 and 1. Considering that flow calibration should be turned off when using PEI Plate (textured one from bambulab) I've read on reddit that you should run flow calibration on cool plate, then switch plate to PEI and everything will go smooth. 0 is a good staring point.
