Bad tool paths

Recommended Posts

I have a couple of small box models I have printed a couple of times. The walls are too thin for infill but they are just 3-5 passes of the print head. The problem is that they take a ridiculous amount of time to print. I’ve watched them a bit and noticed that the print has a really bad pattern. Instead of a continuous line for all of the passes, it will print a line on the short side then travel along three sides before starting to print again and then it just prints the three sides it had just traveled over. Where do I start to figure out why the slicer is generating terrible tool paths.

I'm currently trying to print this design from Thingiverse: https://www.thingiverse.com/thing:2694475

All I did was open them in Cura and arrange the models and hit prepare. I've attached a screenshot of the layer view with just the travel paths. May be hard to see, but it's traveling the whole perimeter of both models multiple times per layer.

I also took a screenshot with the shell paths turned on to show the overlap of them. I would think the only travel that's really needed is going from the starting corner of one model to the starting corner of the other for each layer.

Is there a good way to measure the starting coordinate? When I just set it to User Specified, it set the Z Seam Y to 630mm - a bit outside the 200mm build plate. 

 

I was expecting more time saved, but it seems like it's only shaving a few minutes off. Though the estimates are inexplicably double what they were last time I checked. No other settings changed, so I'm just more baffled.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
