I hab problems with z-axis wobble by printing with the Velleman K8200 printer.
So i hade made some modifikation.
First i had changed the solid coupler (z-axis and stepper-motor).
With the new flex coupler i had the problem thad the z-axis holter starts to wobble.
So i had made a new one to fix this.
Now the printer works correct.
For mountig you need 2x M5x10mm and 1x M5x16mm

Hi, ich habe damals
Layer 0.20 mm
Solid bottom 3
Solid top 5
perimeter 3
infil 0.25 (wabe)
Die Passung des Halters am Profil habe ich extra sehr streng gemacht (Damit so wenig spiel wie möglich ist), da könnten vielleicht noch ein paar Züge mit einer feinen Feile nötig sein (hängt vom Druckergebnis des Druckers ab.
