Retraction settings - one print to speed up calibration!
So you are looking for a way to calibrate the retraction-settings to your 3d-printer? We have a found one guy who had done a google-sheet to programmatically calibrate the retraction. This will test 16 different settings in ONE print.
This is really good - instead of heating up the bed and print a 10 min print. You print this test cube. It will change the retraction speed from 10-150mm/sec and also how much retraction it should test.
Here is a link to the guy who have created the google sheet. We will also put it up on our github account. https://www.cnx-software.com/2019/09/05/how-to-easily-calibrate-retraction-in-3d-printers/
