Hi everyone.😃 I have a problem with my printer... (a Reprap printer) My printer creates a vertical line on the printed part.😐 Printed parts with a circular pattern have this problem more ,like "flower pot". Does anyone know what my problem is? Is this a software(like Slicer,Firmware,...) or hardware problem?🤔 You can see this line in the picture. Regards, freeuser
