A Klipper macro to extrude blobs that can be weighed and input into the spreadsheet from CNCKitchens Extrusion Benchmark System.
If you do not have save_variables setup yet, add the following to printer.cfg and copy saved_variables.cfg into your klipper_config folder.
[save_variables]
filename: ~/klipper_config/saved_variables.cfg
If it already exists, copy the contents into the existing saved variables file.
Copy the FLOW_CALC.cfg macro into your Klipper install and include the macro in printer.cfg.
Configure the saved_variables.cfg defaults to match your printer and restart Klipper.
You can include the macro in other gcode, macros or use directly. When using FLOW_CAL directly from Mainsail, parameters can be set each time from the drop down.
Would execute FLOW_CAL FLOW_START=2 FLOW_OFFSET=2 FLOW_STEPS=4 TEMP_START=260. This would generate 4 blobs ranging from 2mm3/s to 8mm3/s in increments of 2mm3/s.
