Good Day, my Friend!
I posted a long post yesterday (I’m sure you’re surprised it was long, LOL) on Calibration. I mentioned to you I was doing that, it’s mostly done.
It’s not finished since I was very tired and couldn’t post the pictures due to an error in the Forum (now fixed).
It’s meant to help everyone understand the Calibration process better. One thing that I have to finish is the Max Volume test. SoftFever didn’t cover it in the Wiki.
I have a text description done, you might read that, but I didn’t have a good picture of the markers on the end. Your pic is excellent, do you mind if I use it in my post?
The post is here:
@3DTech and @Sticks are giving you great advice, glad to see you moving along!
On the Max Volume test - Those lines on the end help you count. Every large marker is 5mm/sec3. But I’d recommend you read my instruction in that post. You should really start at a higher and end at higher values.
The 200mm/sec3 you see listed is the settings just for the test, to remove any possible limits, you can’t print even close to that value.
It’s very important you don’t change any values when doing a test!!
You also must start a New Project for each test and ‘Discard’ and settings. The tests are predefined for all settings.
It’s also obvious, but easy to forget, that you must save the settings to the Filament Profile once you find the new value! So you end up saving repeatedly. I gave some tips for naming you might read.
I must admit I twice forgot to do the save step in my hurry to do the next test! 
What’s your current Max Flow Rate value?
