Travel issues with PrusaSlicer, how to reduce useless travels?

Hey. I have researched this issue but haven't found a solution that hassled my problem. I am printing a few parts on the plate and instead of printing the objects one by one, which would be a lot faster, the head is literally traveling to each object in between every layer it lays down. This is at least doubling the amount of print time. I would much prefer the extruder to just print an entire object at once instead of moving uselessly back and forth. I have attached screenshots of the plate with visible travel lines, as you can see it travels in-between the two smaller objects in between just about every layer.

I have tried to enable both of these settings per recommendations in other similar posts, but both settings made no difference in the predicted travel of the machine:

Print Settings > Layers and Perimeters > Avoid Crossing Perimeters

Print Settings > Output Options > Complete Individual Objects

The "Complete Individual Objects" seems to be exactly what I need but it made no difference in the predicted travel (the screenshot is with this setting enabled) Any insight, recommendations or info that would help me?

I'm running the latest PrusaSlicer 2.2.0+

RE: Travel issues with PrusaSlicer, how to reduce useless travels?

I ran into a similar issue and finally found out my objects were too tall for the X-axis to pass over them without colliding. even if I put one at the far rear corner and the other at the opposite front corner. If you only had one of the small objects, you could do it because the last object to be printed can be the full Z height. Check out this Knowledge Base article.

The pop-up message for the height is misleading because it doesn't mention the X-axis rods.

I just tested it with 2 small 6 mm high objects and set the extruder clearance to 4 mm, and Prusaslicer would not let me do a sequential print.

Short of placing the two smaller object closer together ( if possible ) to reduce travel distance, I don't know of any way around this.

RE: Travel issues with PrusaSlicer, how to reduce useless travels?

I just created a 30 mm tall cylinder, imported into PrusaSlicer and created 2 more instances. At first It warned me. So I went and changed the height parameter and indicated it was 35 mm. No warnings and it sliced OK. What travel? It is important to make sure that the objects print in the correct order so that you don't collide by moving the X-axis through an exiting printed part! The Knowledge Base article explains how to do this. I started from right rear corner and then center and finally left front corner.

Use at your own risk. Only you know if you have the skills, comfort level, and are prepared if something goes wrong.

Ask your self - is it worth it?

Worked for my test.

Skeptical? Here is my test project. I was wondering how the extruder would move after finishing an object. It moved horizontally to next object and then moved down.
