OMG. I am here. I have the mmu connected. I have the firmware setup and it finally built without error and I got it loaded into the Multi Widow and check out the new menu option for the lcd12864.. I have some calibration stuff to do because of the different length PTFE tubing and stuff. But I am right here. And it is good. Because I really want to dig into my diamond hotend build so I can have and compare 2 different forms of multi material printing.
