Missing spot

Post by LePaul »

I wonder why this print on my UMO keeps missing this one lone spot.

Seems to me to be a combination of back lash and slight underextrusion. Check the overlap settings of your slicer. Cura?

Here what it is, by default in Cura 2.3.0

Again, interesting that it was only that one spot

Just to be sure. Can you check that x/y shafts (the thin ones that move the head) are perfectly square? Just in case.

How would I determine that? Is that the green color?

Here's a layer 1 screenshot with coasting on

Repetier host and gcode.ws show the difference between print and travel moves.

Oh, yes, my bad. They are gcode viewers:
https://www.repetier.com/
http://gcode.ws/

If only someone could invent something like a search engine for the internet... :mrgreen:

... or a search engine for gcode - a possibility to just view travel or print moves could help too... maybe as a plugin? ;-)

You can also open gcode files with Simplify3D. The view will probably not work with feature types but at least you should be able to see the difference between travel moves and regular moves if you set the coloring to movement speed.

In my experience the interface of S3D is much nicer to work with than repetier host, and gcode.ws runs really slowly in comparison.

You could just use your s3d to see the gcode. Coasting shows as no green and just travel move.
