Extruder motor never stop after pause and change filament

raymond

I am not sure whether this is a bug but I believe it is.
For many time when I pause the printing,then change filament use the
Quick setting->change filament command,the extruder motor never stop and keep on pushing the filament out,what I can do is to restart the machine,hope somebody could tell me what happened,many thanks

Check your config for G10/G11 and filamentchange in config tool, especially

Filament change x

[mm]

Filament change y

[mm]

Filament change z lift

[mm]

Filament change first retract

[mm]

Filament change last retract

[mm]

Homing after Filamentchange

No homingHome only x and yHome all possible axis

The retracts are run at the beginning. Maybe you have a big value there.

About this feature,my number is

Filament change x

0[mm]

Filament change y

0[mm]

Filament change z lift

5[mm]

Filament change first retract

5[mm]

Filament change last retract

50[mm]

all default numbers
and when I changed filament right after started up the printer but not after pause ,it worked with no problem.

When you say pause, which kind of pause do you mean? sd print paused, some hosts pause - then which host and what commands got send?
Which firmware version? Always try first upgrading to dev with errors as this is the only version that will receive corrections.

raymond

the version is 0.92.9 ,and I always make SD print.

That might be the problem. Please try calling filamentchange without pause. Problem is that pause and filamentchange both store position and restore position, but only one position can be stored. So that is likely to cause at least a problem. Will remove that in dev version with a test.

raymond

does the 0.91 have this matter?Change filament during printing is very useful feature.

Repetier

I don't think 0.91 has that feature at all.
