Measure 200 mm of filament. There's probably room to go faster without issue and the z-hop distance may even be able to reduce a bit more (though it makes me nervous enough. that results in vastly different flows. Build Surface Preparation & Handling. Q0. Use 1-2 perimeters, or even better the smooth vase mode with 1-2 mm base. ) If your max flow rate calibration is 20mm^3/s then drop it a little, perhaps to 18, just. For further details on the above commands see the RepRap G-Code documentation. This is my first klipper machine - I’ve used octoprint for years and manage a humble print farm of 8 machines, so I have some experience with basic printer maintenance and calibration. I've tested and adjusted my rotation distance but when running SuperSlicers flowrate test I'm finding the +20% flowrate to be producing the best quality print. During this guide, it may be necessary to make changes to the Klipper config file. cfg","contentType":"file. The rotation_distance is then calculated as: rotation_distance = <belt_pitch> * <number_of_teeth_on_pulley>. I tried copying settings and redoing profiles but the only variation afaik was Klipper flavour instead of Marlin in Prusaslicer. The rotation_distance is the amount of distance that the axis moves with one full revolution of the stepper motor. Basic extruder movement is simple to calculate. During this guide, it may be necessary to make changes to the Klipper config file. Read More ». This page is about fine-tuning your first layer squish.

The basic equation would be: New_rotation_distance = Current_rotation_distance * Actual_measurement / Theoretical_measurement. Fortunately, this calibration isn’t ch. However, there is an additional parameter that affects Pressure Advance - the smooth time. Usage. ** Remember** to save the filament profile. A calibration script provides an estimate for max_accel parameter that should not create too much smoothing. Now from within the 3D slicer set bottom layers to 1. FAQ: Frequently asked questions. At 100% flow this ends up with the same issue, hot end hitting previous layers after around 5 layers and then having to constantly adjust it every few layers. In particular, in order for the system to implement the simultaneous calibration it will be necessary to save and restore the low-level Z height probing results so that they are available when the user later enters the XY dimensions. than macros. 2. Next step I would do would be to use a caliper to measure 100mm of the Y axis. Andrew Ellis’ Print Tuning Guide goes into more detail about print tuning. . 99. If you set flow to 80% in Cura, then set Klipper/Mainsail to 80%, you'll end up with 64%. Tuning efforts at the beginning (this tuning guide!) will have a much higher relative quality increase, but you get diminishing returns the closer you get to perfection. Next, plug the SD card in your printer and turn it on. 4mm nozzle and 0. First determine the type of belt. If you have printed several walls, you have to divide the value by the number of walls.
