Extruder problem after updated the firmware

K8200 3D Printer K8200 - Issues while printing
1

Hello everybody

I have updated the firmware to MARLIN V2.

and now , during the first printing , the stepper of the extruder turn slower than expected , and the first layer is not good !!!

I would like to increase the speed of extrusion , or is there another solution ?

How I do ?

thanks

Fabien

Did you load the firmware for the K8203?
If you still have the stock extruder you need to use this firmware.

I have upgraded the firmware with “FIRMWARE K8200 V2.1.1.ZIP” for k8200

and I think that the problem appears on the first layer only , then the extruder speed is normal after that .
