SV04 Head2 goes to the center even if there is nothing to print... (used to print support)

Hello

I’m trying to print a model in dual mode. Head 1 is printing the model and head 2 is used to print the support.

The problem is that for every layer the head 2 is being heated up and moved to the center of the bed even if there is nothing in that layer to print.
This makes also the filament to be retracted every time until its totally removed from the head and then when its needed for print there is no filament available in the traction portion of the head.

I checked the G code and found this in every layer

G1 Z{retraction_hop_height_after_extruder_switch} F12000
G1 E-3

G92 E0

This shows what is happening. The head waits to the temp. Go to the center of the bed dont print anything retracts the filament and goes back to the home…

try to print other dual models and see if there is the same problem. You can try to print dual models of random files. File link:

If the same thing happens with the dual model that prints the random file, it may be a problem with the firmware, and re-flash the firmware.
