Strange Anomalies in preview Gcode. Mirrored in Part

Mon Oct 28, 2019 6:18 pm

Hi all, I am experiencing a strange symptom that's driving me nuts... I am getting strange blobs on my prints but on looking closer these blobs are in the preview... here is the Preview :-

This is the print I get with this Gcode :-

As you can see the same blobs from the preview are in the part. I have checked to see if these blobs match layer to layer in the preview and they do.

If anyone has any idea how to solve this I will be extremely great full.

Thanking you all in advance.

The blob in the preview are where retractations take place(you can uncheck an option to no display them in the preview), and retractation may produce blobs when printing.

Just to add on to what was said previously I would suggest checking out our Print Quality Guide section that covers blobs and zits. There are some great tips there for combating retraction defects. I included the link below.
