 24. gneu feedback on EndlessSpool: (2 ideas and 1 possible bug)
 I came across a mistake of mine, that makes me think about a few mods that could improve ES.
 Yesterday I was printing something and in the middle of the print I saw that ES was required.
 I stated the print with T9. When I noticed that I didn't had enough material to finish the print, I started to set up ES while printing.
-I installed a new spool on T2 and modified TTG map so that T2 will be the next ES spool for T9. However I forgot to make T2 available. I could not check the gate because T9 was printing. When the ES was detected, of course he told me that T2 was empty and went to pause. I didn't all that was needed to make T2 working, and finish the print.
-> The first mod could be that when you add a tool in the ES mapping, that tool (T2 in my case) is automatically made available.
-On the next print, T9 and T2 were still mapped together for ES, so I thought that since it had detected ES on T9 it would start on T2. But he didn't. So I had to pause and load T2 manually.

 What do you think ?

-> The first mod could be that when you add a tool in the ES mapping, that tool (T2 in my case) is automatically made available.
-I agree that would be sensible thing to do automatically.  Just so you know you can manually set it to "available" with the MMU_GATE_MAP GATE=xx AVAILABLE=1 command, but it should be automatic.
-> The next mod could be that when ES is detected on a gate, that gate is declared empty automatically.
-This is what it is suppose to do and was sure it did.  Did you do something that could have caused it to be marked available again?  Or maybe the tool-to-gate map started with the wrong gate.  I'll have to look into this one but sounds like a bug.
-> When the spool detected as empty, the unload could go a bit further than park the filament in the block. It could unload 20mm further to make sure that the gate is empty.
-Can you explain this more? Do you mean the unload of the filament that has run out could go further? If so, then yes, this is a good idea!

-25. Need to use ES groups for initial load if desired gate is empty!
-I forced T9 empty, hopping that T2 will load and start the print. 
-It didn't. It just stop the print. Although T2 and T9 are mapped together for ES.

-26. Gate calibration - maybe throw away the first measure unless the gate is buffered for more accurate results
