Proper Workflow for Enhanced Delta Calibration

General Discussion
1

Basic Information:

Printer Model: Flsun QQSP
MCU / Printerboard: “hispeed” (robin nano)
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

I am in the process of calibrating my delta printer.
I have been using the guide for the “Enhanced Delta Calibration”

My process is as follows:

1 - Heat bed and nozzle to working temps
2 - Wait ~ five minutes
3 - DELTA_CALIBRATE
4 - SAVE_CONFIG
5 - Print “calibrate_size” model with recommended slicer settings
6 - Measure and enter all measurements
7 - Enter SCALE
8 - Then ANALYZE
9 - SAVE_CONFIG

After these steps ^^ I move to verify proper calibration:

10 - Heat machine again
11 - BED_MESH_CALIBRATE
12 - SAVE-CONFIG
13 - Print “calibrate_size” model with recommended slicer settings
14 - Measure model and find model not quite perfect. I would like to calibrate again…

At this point, do I simply start at STEP 1 in order to perform a second Enhanced Calibration to achieve even more accurate results?

Thanks

As I asked, do I start a subsequent calibration from STEP 1?

Or do I need to do something special between calibrations?

The guide does NOT describe how to proceed with subsequent calibrations.

The guide ONLY describes how to perform a single calibration.

One can assume that the process can simply be started over, however the guide could simply state this if it is true or not.

Maybe add this to the end of the guide:

…IF THE RESULTS FROM THIS PROCESS ARE NOT SATISFACTORY, YOU MAY START THE PROCESS OVER BY PERFORMING A DELTA_CALIBRATE, THEN SAVE-CONFIG COMMAND FOLLOWED BY THE REST OF THE CALIBRATION PROCEDURE…

OR this to the start of the guide:

…IF YOU HAVE PREVIOUSLY COMPLETED AN ENHANCED DELTA CALIBRATION, AND WOULD LIKE TO PERFORM A SUBSEQUENT ENHANCED DELTA CALIBRATION TO FURTHER INCREASE THE MACHINE’S GEOMETRICAL PRECISION, YOU MAY RE-RUN THE ENHANCED CALIBRATION PROCEDURE BY STARTING HERE:…

An actual answer would be nice instead of posting a picture of the same muddy language that is in the guide.

Thanks

You can start over from step 1 if you wish. If the endstop positions and bed have not physically changed then there is unlikely to be a benefit in starting from step 1.
