It seems I just keep having problems with S3D since the update. Maybe coincidence but it is strange.

Anyway, printing this part. PLA, 210, 60, 3600mm/min., layer is .32 .4 nozzle solid infill. Start points are set to specific point and as you can see the beginning of each layer is pretty bad. Otherwise the print is very good.

Don't have the factory available right now but thanks for any initial thoughts.

Have you tried playing with the extra restart distance ? From the looks of it, it is overextruding slightly at the beginning of the print, could also be ooze. I would definitely tune the retraction, especially the length and the extra restart.

Not a great angle on the print but that is all gaps and missing filament not over extruding. It takes it until it gets to the first corner on the right of the print to start extruding ok.

Then you should just go the other direction to adjust the Extra restart distance value. Is this a bowden extruder ? What is your retraction distance and speed ?

This is a QIDI Tech-1. I am thinking I had wipe on and wondering if that could be part of it. I'll have to double check retraction and speed also. Didn't notice the problem until later when I was away from the printer so can't check yet.
Never really had this issue with this printer.

The issue you commented on, the blobs etc at the start of a layer especially on a cylinder is a big problem. I have been able to reduce it with a negative restart but that creates issues elsewhere.

Here is another pic.
I turned wipe off and reduced retraction settings to their defaults. It improved a tiny bit but negligible. I am also printing outside-inside.
I'll attach the factory later today.
This problem area is a layer start point and it looks like the first outer part is under extruding and not sticking. I have not tried one inside-outside yet as I wanted the best outer layer possible.

I have added the factory file. Thanks for any ideas!!

I usually find that inside-out perimeters give better results on my machines, so make sure to test both on your printer

Yea, I did and inside - out is much better. Odd thing is they say that the outside - in is supposed to give a better exterior. I would like to try to improve this though.

I ran it with inside-out and the exterior is better but the problem moves to the inside walls of the part.
