I ran the following commands in pronterface to try extrusion of mix colors but failed. The system is hangs after I trigger the extrude button in pronterface.

Extruding 20.000000mm of filament. <--- Here I try to trigger extrude button Warning: Mix factors must add up to 1.0. Scaling.

m163 s1 p0.5

Extruding 20.000000mm of filament. <--- once I click extrude again, the system is hangs, the LED on mega256 board is keep flashing endless

My 3D printer is delta type. it has 3 extruder motors attached. 2 of them are attached to main board which is mega2560, the last one is attached to external CNC extension board. The hardware circuit was well tested with old non-multi-extruder support marlin firmware. I can switch between all 3 extruders via pronterface software. Once I switched over to MarlinDev firmware with multi-extruder support. It stills can extrude the primary filament via the LCD rotatory control manually.

Hi @DIYlover – I'm the person you want to talk to about this feature, and it definitely could use some testing. I suggest you switch away from MarlinDev and pick up the code at #3655 instead. The full branch is at http://github.com/thinkyhead/Marlin/tree/rc_mixing_extruder.

Thank you for your interest making Marlin better and reporting this issue but this topic has been open for a long period of time without any further development. Marlin has been under heavy development for the past couple of months and moving to it's last mile to finish the RC cycle and release Marlin v1.1.0. We suggest you to try out the latest RCBugfix branch and reopening this issue if required.
