I am using a quad filament dual nozzle Chimera hotend with dual y splitters.\r\n\r\nAlright at about layer 5 to 6 I get the Move exceeds maximum extrusion (148945865169661280.000mm^2 vs 6.000mm^2) during my filament switching gcode which is this so this means this code works fine for a few times before this.\r\n\r\nT[old_tool]\r\nG1 E-4  F5000\r\nG1  Y10 F15000\r\nG4 P1000\r\nG1 E3.9 F4000\r\nG1 E-20 F1200\r\nG1 E20.5 F4000\r\nG1 E-120 F4000\r\nT[new_tool]\r\nG1 E110 F2000\r\nG1 E3 F300\r\n\r\nI have removed all coordinate switching commands that I could find to make sure this wasn't an issue.\r\nAlso does it on different models.\r\nI can print with one filament just fine, but when I go to do multiple materials it does this error.\r\n\r\nI went through all the logs/gcode to see if anything was causing this and couldn't find anything.\r\n\r\nAlso I have this same gcode running a a smoothieware based board just fine.
