Fillament feed power

Vertex 3D Printer Vertex - Issues while printing
1

Hi, I have a problem with my vertex k8400.

when I start printing the first layer do not attach to the building platform but when I manually increase to force on the filament throughput, more filament obviously goes through and the print goes very well as long as I push the filament trough.

the nozzle seem to be blocked quite fast and the first layers not sticking is also a problem I think are all related to the force with which the filament is fed into the nozzle.

I have found some treats which more or less describe the same problem but they don’t have a final description of the solution.

Hope some on can help

This could be 1 of 2 things or both.
Re calibrate the X axis it maybe to far from the bed
Check the screw that holds the pulley to the shaft of the motor of the extruder it maybe slipping.

I have calibrated with the folded paper but I will try again and play with it some more.

Which screws do you mean because the pully that pushes the filament through the tube only has a spring but no screws to tighten it more.

The screw that hold the pulley on to the shaft.

While you are working on it make sure the alignment of the pulley is correct.
