Welcome to the SeeMeCNC Community

I just found this handy tool. It's a simulator for GCode, where you can watch the movements of your machine.

http://gcodeprintr.dietzm.de/

Just load a gcode file and watch what your printer is doing in a simulation.

I used it for examining the temperature changes in a calibration print to find the right temperature for the extruder.
In another print with two seperate parts, it switched between the parts and so there was some blobbing at an inconvenient place, so i rotateted one part and viewed the movements in the simulator and now the parts are perfect.

So try it out, its free and it's in java, so it should run on every platform.

(I have no affiliation with the developer, it's just a useful tool...)

Just downloaded and tried it. Been looking for something like this. I wish it was integrated in slicers, probably will be. Thanks for the heads up

The one that's built into S3D helped me solve a problem with a complex model. I was able to quickly try different things until the simulation showed it printing ok. Then tried the print and other than stringy, it was fine.
