Ultimaker Cura plugin to adjust settings for Pressure Advance feature of Klipper firmware.

PressureAdvanceSettingPlugin

Compatibility tested up to Cura version 5.0.0 (SDK 8.0.0)

My new KlipperSettingsPlugin includes Pressure Advance and a number of other Klipper features. Give it a shot!

Unofficial Cura plugin which adds the feature option "Enable Pressure Advance Control". When enabled, a number of feature-specific "Pressure Advance" subsettings are added to the Material category in the Custom print setup of Cura. Is NOT compatible with Marlin's Linear Advance.

Designed to work natively on any printer running Klipper with Pressure Advance enabled. Fully compatible with multiple extruders and Cura per-object settings. Does not currently support changing pressure advance smooth time.

This is a work in progress that has improved significantly thanks to user feedback. Due to all of the variables it's difficult to test so I appreciate input from those making use of it. It is based on the LinearAdvanceSettingPlugin by Cura guru fieldOfView which had compatibility issues with Klipper. Features have since expanded beyond the scope of the original plugin but it is still the backbone that makes this possible.

The plugin inserts the following command into Cura gcode as needed:

SET_PRESSURE_ADVANCE ADVANCE=<value> EXTRUDER=extruder<int>

Current Release Notes (v1.4.0)

• Now compatible up to Cura version 5.
• Pressure advance control is now easily enabled or disabled with a single check box.
• Added feature setting support for individual mesh objects.
• Fixed reliability issues when using multiple extruders.
• Support infill and interface settings now grouped under a single support option.
• Minor updates to setting definitions.

Bug Fix (v1.4.1)

• Disabled per-mesh setting support and "prime tower" option for older Cura versions.
• Fixed error when only extruder used is not number 0.

Multiple Extruders

To improve reliability, active tool head numbers are now set by detecting Tool Select commands in gcode (T0, T1, T2...). This is then translated into Klipper's standard naming convention of 'extruder', 'extruder1' and so on. I could not get this technique to fail in testing but custom extruder names or plugins/scripts that modify tool change behavior may not be compatible.

How to Use

The Enable Pressure Advance option is added to the bottom of the Material category and effectively enables/disables this plugin. When unchecked, no commands will be added to final gcode. This does NOT mean pressure advance is disabled. To command Klipper to disable pressure advance, enable control and set values to '0'.

When Enabled, most feature-specfic settings can be adjusted:

Extruder Settings

Check setting visibility if options are missing.

Per-Object Settings

Per-object settings available in Cura version 4.7 and newer.

Any defined subsettings will always override the primary factor value. Setting only the primary value in per-object settings will override all extruder settings for that mesh but will not affect non-mesh features (first layer, skirt/brim and supports).

If you're wondering who could possibly need to change all of these, you're probably right. Most users should save profiles with the primary value and leave the rest hidden. Advanced users will likely see a benefit from controlling features like walls. Reducing P.A. for infill, skin or support may reduce excessive extruder movement on machines requiring high values, especially at high acceleration. Per-object settings were primarily added for testing to make it easy to quickly print multiple test geometries using different setting combinations.

Installation

Not currently available in the Cura marketplace. I am working on creating a .curapackage for streamlined installation but this is currently beyond my knowledge. If anyone would like to assist me with it, please let me know.

If Plugin Already Installed

Simply replace the old files with those from the latest release. Make sure all files in the folder are replaced. Any extra files in your folder are likely temporary and can be left alone or deleted. If you have issues, remove the entire folder and install again as instructed below.

Install from Source Files

Uninstall LinearAdvanceSettingPlugin, if already added to Cura.

Download PressureAdvanceSettingPlugin source .zip file from Github.

Open Cura, click 'Help', 'Show Configuration Folder', then navigate to the "plugins" subfolder and unpack .zip file there. Rename folder to "PressureAdvanceSettingPlugin", removing suffix added by Github (e.g "-master").

Repeat process for subfolder of the same name.

pressureadvancesettingplugin's Issues

Not working in Cura 4.13Beta

can't find any pressure advance command in g-code from Cura 4.13 so I created M900 macro, with K-factor from Marlin's linear advance plugin

Couple of questions regarding proper use of this plugin

Should the pressure_advance value be removed from Klipper's printer.cfg to use this, or does the value specified in Cura alway override this?

What happens if I leave the value at 0 in Cura, will Klipper still use the value in printer.cfg or will it be forced to '0'?

Thanks for creating this!

Pressure Advance command always sent / make it selectable

Hi.

your plugin is very helpful, thanks for the work you put into it!

I use Cura with different printers, some of them do not understand the SET_PRESSURE_ADVANCE line in the G-Code and stop printing.

I tried doing a search & replace postprocessing to delete the SET_PRESSURE_ADVANCE command, but it seems that the line gets inserted after the post processing. So no luck.

Would it be possible to add a setting where you can turn on/off the PA setting per "print setting" and thus the SET_PRESSURE_ADVANCE does not get inserted (and on Klipper printers the Pressure Advance setting of the printer.cfg is used)? This would also prevent existing profiles (where one forgets to update the PA settings) overwriting the printer.cfg setting ;-)

Or could you run the PlugIn before Post Processing is done? The Post Processing scripts are stored per printer, so it would work.

Thx a lot!

What is Pressure Advance Factor... why not pressure advance in mm....??

I know exactly what my pressure advance needs to be in mm...
what is the factor value multiplying from?

in my case, I am printing at 80mm/sec, and I know my pressure advance needs to be 0.50 for that speed based on a pressure advance test in orca slicer

Does that mean my pressure advance needs to be a factor of .00625?
