Operating System (OS)

Windows

OS Version

windows 10

Additional system information

When using the Flashforge ad5x with the ifs module (multimaterial-multicolor) attached it seems like orca cannot ptoperly tell the printer which slot to use. Prints are

Printer

Flashforge AD5X

How to reproduce

finish a print using the ifs: the printer will retract the filament into the bowden tube leaving the extruder empty
send any file from orca to the printer (the printer will default to not use the ifs but expects filament already in the extruder)
printer will pause once heated because there is no filament in the extruder

Actual results

the printer throws a filament runout error because in fact the extruder does not have filament in it

Expected results

the printer should load the filament from the chosen slot
in orca-flasforge there's a ui to monitor the printer and to manage the ifs and to choose whether to use it when sending file for printing

Project file & Debug log uploads

In the project there are multiple filaments mapped to the slots on the printer

Anything else?

currently there's no way of telling the printer to use the ifs and which filament to use. the only way to do so is to upload the file only (or use usb) the print from screen enabling the use of the ifs through the option on the screen before printing
