5 Best Free OBJ to GCode Converter Software For Windows

Here is a list of best free OBJ to GCode converter software for Windows. Through these software, you can easily perform OBJ to GCode conversion. This conversion is performed to directly feed the GCode of an OBJ model to a 3D printer to print a physical 3D model. Apart from OBJ, these software can also convert models of DAE, STL, PLT, WMF, and other formats to GCode.

Before starting the conversion, you can adjust various printer settings and specify some commands for the 3D printer. To include printer instructions in GCode, these software provides tools like G-Code Constants, Step Over, Offset Direction, Feed Rate, Material Type, etc. After that, you can start the conversion process. To help you out, I have also included steps to convert OBJ to GCode in the description of each software.

These converters can also be used for viewing an OBJ model as they all offer multiple viewing tools like zoom, pan, rotate, etc. In most converters, you also get many model editing tools to modify the native structure of the model like Fillet Corners, Node Edit Mode, Join, Normal Edit Mode, Shapes, etc. Additionally, through some of these converters, you can also directly operate a 3D printer. Go through the list to know more about these software.
