Hotend Switching Problem

Hi, i switch between two hotends using the Fan2 Signal and a Tool change script in Slicer. However the tool change happens 2 seconds before the layer ends. I checked the G-Code which turned out to be correct. Now i'm questioning if something in the Firmware can lead to that issue. I'm using 1.0.0dev on a Radds 1.5 Board.


  • Fan2 is executed when parsed regardless of the move state. Prepend a M400 to wait for end of moves and then toggle position. Or go even a step further and use our SELECT/DESELECT commands in firmware and put the code there. Then you only need to T1 / T0 for switching.
