print is not clear

[sergei]

I have Duet Ethernet. the firmware seems to be configured with. but I can't understand. the problem is the following when printing in one color all the rules. the part is printed. but when printing in two colors (I have a printer with two nozzles), the printing is strange. Yes, you can say nothing at all. I load the g-code, I warm up the extruders and the table and start printing and immediately on the first layer the speed of the head movement is reduced to nothing, and so it only periodically moves, and the filament feed becomes very fast. what could be a problem?

@sergei As @Veti says, please don't start multiple threads on the same subject. Though it would have been useful to have this actual description in the thread I replied to. I'm locking this thread.
