Best slicer ?

Hello everyone ! It's been a little while since I use my Robo C2 regularly and generally, it works pretty well so I'm happy !

I always used the slicer Cura and it does a good job. But sometimes the prints are not as good as they could be, and I feel like I could get better prints by tweaking some advanced settings in the slicer. For instance, I want to be able to control the exact path of the nozzle (especially for the 1st layer to look and stick better to bed), or move the bed down a bit during travels, etc. In general, visualisation of the full path of the nozzle is a big plus for me I think.

Simplify 3D, for instance, looks like a very good slicer, I was wondering if it's worth the price, what do you think ?

Or do you have some other suggestions, maybe ?

Thanks for your help !

 

Thanks ! I downloaded a torrent of S3D (to have a try, after that I might buy it). But I have a problem, I can't export anything into gcode from STL files. There is normally a preview in S3D, but it's totally empty, like this :



When I open directly a gcode file generated with Cura, it shows it fine in the S3D preview like this :



I don't understand why I'm unable to generate any gcode with S3D, is it something related to the machine or firmware settings ?
I tried to copy the machine settings from Cura, but not sure if it's right (?), here are my settings :



About the firmware configuration, I understand NOTHING about this, what the hell are those settings ?? How should I configure them for a specific printer ? (Mine is Robo C2) Could this be the cause of my problem with the gcode being empty ?



Thanks in advance for your help

 

For more info, here are the 2 different gcode outputs, from Cura and from S3D, from the same STL file.
