Upgraded to 1.20RC3 and Mixing Tool Changes no longer function….



  • I upgraded to 1.20RC3 this morning and tool changes on my mixing delta no longer function. Selecting any of the tools in DWC produces a "Attempting to extrude without having a tool selected error". I heard the extruder motors making strange noises and I shut the printer off and on before the hot end was jammed badly. I had this bug occur a while back in a previous build. It caused a great deal of havoc to my hot end.



  • Checked after power cycle, printer appears to be functioning again. I did do a M502 and M500 after upgrade that might have done something to create the issue.
