Hi,

I’ve have problem with prints quality. As you can see on bellowed pictures on calibration cube and benchy surface is wavy. It’s overheating of the material? How to prevent ?

Hi @lukas4,

have a look at the results of my test prints (printed with Z-PLA Pro, exactly the same settings):

Please, run the fan test to ensure the fan coolers are operational. Also, while printing small models - you can increase the fan speed in Z-SUITE instead of using automatic one (if you set it to 100% - please remember to use low infill density).

Have you tried printing with other materials? Are the results similar? Also, how many hours has the printer done so far, did you already replace the hotend module/nozzle?

Best regards,
Karolina
