Extruder Motor problems, with Marlin Beta and new Netfabb

Recommended Posts

Posted · Extruder Motor problems, with Marlin Beta and new Netfabb

Hi,

I have updated my Ultimaker with Marlin from Erik Zalm and downloaded the new Netfabb with 250'000 baud connection.

In a test print, all goes well at the beginning, but at infill, the extruder motor starts to turn really fast! So fast like i have never seen it.

The bolt turns itself into the filament and no more is extruded. Also it would be too much filament for the current printing speed.

Anyone had the same problems?

Regards

Dingo

you need to put M92 E14 into the beginning of your gcode, otherwise it will run with E925, which is obviously way too fast...(I'm surprised that you even get an usable extrusion for your non-infill)
