Why does my actual cut part not look like the Preview Image?

The more you use our programs, the more you will appreciate the accuracy of the Toolpath Preview and how it can help achieve superior results at your machine.

However, there are issues beyond the program's control that can result in your machined project not looking like the Preview image.

There could be many reasons for this, but here are a few to consider and check:

  • Do not setup a toolpath that exceeds the cutting length for the bit you will use.

  • Be sure you set Z Zero at your machine to the same point (Top of Material or Top of Machine Bed) that was set in the program when the toolpaths were calculated.

  • Be sure you set the X,Y Origin to the same relative position at your machine that was set in the program when the toolpaths were calculated.

  • Be sure you have installed the same bit at your machine as the toolpath was calculated for.

  • For V-carving, it is very important to use the exact same angle v-bit as the toolpath was calculated for. A different angled v-bit may have been installed at the machine OR the actual angle is slightly different that what the bit manufacturer marketed it under. A forum member, Paul Z, has developed a quick and easy way to find out exactly what angle your v-bit is without the need for expensive measuring equipment. Click here to see Paul Z's guide.

  • Verify the actual Material Thickness matches the Material Thickness set for the project.

  • Double-check all the Tool Database setting for the bit you are using. Sometimes it is easy to create or copy a tool and input the wrong diameter.

  • Verify the Feed Rate and Plunge Rate settings are correct for your machine and material, and have the units you want.
