K8205 paste extruder moves opposite direction


#1

I have got K8205 upgrading kit. however when i print the paste extrude moves opposite direction to upwards rather than going downwards for printing. The problem is that the motor moves in anticlockwise direction which moves the top gear in clockwise direction taking the paste extruder upwards. I have also switched the driver board . can you please tell me how can I change the direction of motor so the paste extruder pushes paste downwards

In the firmware under configuration.h
look for this line and change it
#define INVERT_E0_DIR true // for direct drive extruder v9 set to true, for geared extruder set to false
Set it to false

I get this window under firmware in configurations

You will need to download the firmware from this link
http://www.k8200.eu/downloads/files/downloads/firmware_k8200_marlinv2.zip
You will also need the Arduino IDE from this link
https://www.arduino.cc/en/Main/OldSoftwareReleases#previous
Do not use anything above 1.0.6
Load the firmware into the IDE then click on the tab at the top "Configuration.h and look for the line #define INVERT_E0_DIR true // for direct drive extruder v9 set to true, for geared extruder set to false
Set it to false
then load it to the control card.
You can find the instructions here

There maybe a way in the firmware but do not know where it is
A quick way maybe in manual control.
To speed up just the extruder adjust the Flowrate
To speed the machine adjust the Feedrate.
