I'm new to 3D printing, but have been having relative success with the Ender 5 Pro and Cura.
I'm making some coasters and using the ironing feature to smooth out the top layer. This is mostly working great, but there are lines left on the surface, consistent between identical prints. They appear to be seams between different ironed areas. They form when one continuously ironed area finishes, the nozzle leaves that area, then an adjacent area is ironed later, forming a seam between them.
I'm using the default ironing settings, on only the top layer. I have no clue what settings might be causing this, or if this is an avoidable issue.
Any ideas from more experienced printers?
