That’s the exact guide I’m currently working my way through 👍

I suffered 3 long years endlessly upgrading, tweaking, and maintaining an Ender 3, so I definitely know your pain! 😂

I just realized that I have that capped, and I’m now running some flow rate tests on my different filaments. I’ll make another post with the highest flowrate I achieve 👍

Heh - I currently have everything set up for the glass bed mod, except I just read that it doesn’t work with the CR touch sensor, so I’ll need to get a BT Eddy sensor or sonar something. I’ll also need to print a new gantry, and I’ve already tried one that didn’t work as well as the stock one, so just waiting to do more research on that, and then I’ll have my glass bed all set up!

Edit: oh yeah! So the way I calibrated it was:

• I removed the extruder from the gantry (3 screws)
• I fed in some filament (cold, obv) until I could see it on the bottom of the extruder
• Flush cut the filament
• Issue some commands to extrude 100mm
• Flush cut that segment off again (try to cut exactly the same as before)
• Use digital calipers to measure that piece
• then just calculate your new value and run the test again to see if it extrudes exactly 100mm
• enjoy amazing prints
