The finishing pass can take several hours, so longer cutting times aren’t necessarily unusual. However, if your roughing preview looks almost identical to the finished carving, I’d recommend going back through the toolpath setup in the Reptile Relief project lesson.

Here are a few things to double-check against the lesson:

• Roughing bit: 1/4″ endmill

• Finishing bit: 1/8″ ball nose

• Material thickness: 1.25″ (adjust to your actual board)

• Project size: 4.75″ x 16″

• Z-zero: Top of material

Once you’ve reviewed those settings, recalculate both toolpaths and run the simulation again before cutting any material.

As for the Carbide Create file only showing the crocodile’s outer profile, that sounds like something specific to how the 3D model is being displayed or handled in Carbide Create. I’d recommend reaching out to Carbide 3D’s support team for help with that part.

The basic version of Carbide Create won’t support the 3D carving toolpaths needed for the crocodile project. You would need either Carbide Create Pro or Vectric VCarve (or higher) to create the 3D roughing and finishing toolpaths.

As far as which file to use, Carbide Create Pro supports importing STL files for 3D carving. However, Vectric project files won’t open directly in Carbide Create.

Hi Bruce,

Thanks for reaching out, and no worries at all on the computer side of things. There’s a lot to learn when you’re getting started, especially when the software on your screen looks different from what Andy is using.

For the 3D Crocodile project, the course playbook is set up around Vectric VCarve or above. After downloading the project folder, you’ll want to extract the zipped folder and then open the included project file in Vectric. The project uses two separate 3D toolpaths: a roughing pass with a 1/4″ endmill and a finishing pass with a 1/8″ ball nose bit.

Your Shapeoko 5 Pro is absolutely capable of doing this type of project. The playbook even includes recommended starting settings for a Shapeoko or similar machine.

Hope that helps,

Miranda

Hi Peter,

Welcome to CNC! This part can definitely feel confusing the first time, so I’ll break it down in plain language.

The big thing to understand is that you normally do not send the actual Vectric project file straight to the CNC.

Think of it as three steps:

Vectric = where you design the project and create the cutting instructions.

G-code = the finished set of instructions your CNC can understand.

Nighthawk/controller software = what sends those instructions to the CNC machine.

So your basic workflow looks like this:

1. Open your project in Vectric.

2. Make sure your material size, thickness, toolpaths, bits, and zero position are correct.

3. Use Vectric’s toolpath preview/simulation before exporting anything. This lets you check that the cuts look the way you expect.

4. Once everything looks correct, save or export the toolpaths as G-code.

This is the important part: when Vectric asks for a post-processor, you need the post-processor that is correct for your QB2 V2/Nighthawk setup.

A post-processor is basically a translator. It tells Vectric exactly how to write the G-code in a language your particular controller understands.

5. After saving the G-code, that is the file you would load into the control system that operates your CNC.

Where I don’t want to steer you wrong is the exact Nighthawk/QB2 V2 post-processor and transfer procedure. That is specific to your machine and controller. The best next step is to contact the manufacturer or dealer for your QB2 V2/Nighthawk system and ask them:

“What Vectric post-processor should I select for my QB2 V2 CNC using the Nighthawk controller, and what file type do I load into Nighthawk?”

They should be able to give you the exact post-processor name and show you where that exported G-code file gets loaded.

Hope that helps,

Miranda

Hey Chris,

Vectric is a great software that is easy to use and would be good for the projects you are making.

Hey Morris,

When you open the image, you should be able to right click and save the file.

[Miranda]

Hey Victor,

Nobody else has mentioned this issue, so it may be something on your end.

Hey JD,

I’m sorry the course isn’t what you expected. Our goal is to give those new to CNC the files already created so that they can have success in completing a product. We do not go into how to create your own files, as that is a more complicated process that isn’t needed to get started.

[Miranda]

The Coolook CNC400 isn’t one of the machines we have a verified configuration for, so I don’t want to point you toward a generic machine selection and have you choose something that may not match your CNC.

For the machine-specific setup and GRBL configuration, the best next step is to follow Coolook’s setup instructions or reach out to their support team. Every machine can behave a little differently, and they’ll have the correct settings for your specific controller.

Sorry I don’t have a specific answer for you!

Hey Kevin,

First, double-check that you downloaded and extracted the Crocodile project file from the lesson and that you opened that extracted project file in VCarve Pro. Then compare the toolpaths shown in VCarve with the roughing and finishing toolpaths demonstrated in the lesson.

If the correct Crocodile project file is open and VCarve Pro 12.510 is still only showing a profile toolpath, that becomes a software-specific issue. In that case, I’d recommend reaching out to Vectric’s support team so they can check how your version is reading the project file.

Hope that helps!

Hey Michael,

Since locating those settings is specific to the software, the best place for help with the menus and interface is the official support team for the software you’re using. Different versions can place the controls in different locations.

Hi Terry,

Great question. I can see why those numbers caught your attention. A spindle speed of 6,500 RPM is much lower than the settings used throughout CNC Kickstart.

For the Genmitsu 4040 Pro Max, the course generally uses these starting ranges:

• A 1/4-inch downcut bit runs around 50–75 IPM and 16,000–18,000 RPM, depending on the material and project. – A larger 3/4-inch bowl and tray bit runs around 30–50 IPM and 14,000–16,000 RPM, with lighter 0.05–0.07-inch passes on a budget machine.
• A 1/4-inch roughing endmill is shown at 50–70 IPM and 18,000 RPM on the 4040 Pro Max.

Based on those course settings, I would not automatically lower the spindle to 6,500 RPM just to reach a larger calculated chip size. The course takes a more practical, project-based approach. It keeps the RPM in a normal working range for the bit and adjusts the feed rate and pass depth to match the machine.

Since your priority is cut quality, I would start with the CNC Kickstart settings rather than replacing them with the Claude chart. Keep the feed rate within the 4040’s limits, use the lighter pass depths shown for the budget-machine setups, and test the cut on scrap material before running the finished project.

The biggest thing to remember is that every chart is a starting point. Material, bit condition, machine rigidity, pass depth, and workholding can all affect the finished cut. Make one small adjustment at a time and judge the result by cut quality, machine sound, and how cleanly the chips are clearing.

Hi Joseph,

I totally get how frustrating that is, especially after trying several fonts and bits.

From what you described, the font probably isn’t the main issue. The “B” losing its center is a strong sign that the lettering is being run as a pocket toolpath rather than a V-carve engraving.

In our project workflow, lettering and engraved details are set up with a V-carve toolpath using a V-bit. Pocket toolpaths are used when the goal is to clear an entire area. A 30° V-bit works well for smaller, detailed lettering, while a 60° V-bit is commonly used for larger engraving.

Inside your design software, try this workflow:

• Select the lettering vectors.
• Create a V-carve toolpath instead of a standard pocket.
• Preview or simulate the toolpath before cutting.
• Look closely at letters such as B, A, D, O, P, and R. Their enclosed centers should remain visible in the preview.
• Test the setup on a scrap piece before running the finished board.

Changing between bold and regular fonts or adding spaces won’t correct a toolpath that is clearing the wrong area. Get the preview looking right first, then choose the V-bit angle based on the size and detail of the lettering.

Hope that helps!

It sounds like the version of VCarve you have installed may not be compatible with the project file. The best next step is to visit Vectric’s official website and download the current trial version:

https://www.vectric.com/free-trial/

If you still get a version error, I recommend reaching out to Vectric’s support team. They can confirm which version and edition you need to open the file and help you get the correct software installed.

One thing to keep in mind: the VCarve trial is great for learning and previewing designs, but it only allows test cutting with Vectric’s designated trial-compatible projects. To cut a regular course project, you’ll need the appropriate licensed version of the software.

Thanks for reaching out, and I’m glad to hear you’ve been enjoying the Kick Start Program!

For the Reptile Relief project, the course workflow is to download the project as a zipped file, extract the folder, and then open the extracted project file in Vectric. The project is designed for Vectric VCarve or above and should include both a roughing toolpath using a 1/4″ endmill and a finishing toolpath using a 1/8″ ball nose bit.

Since you’re only seeing an edge profile in the .crv file, I’d first go back to the Reptile Relief lesson and download the project file again. Make sure you’re opening the extracted project file from that download rather than one of the other files in the folder.

As for VCarve Pro not recognizing the .crv3d file, that part is specific to how Vectric handles that file type and software version. Vectric Support will be the best resource for confirming whether that file can be opened directly in VCarve Pro 12.509 and what the correct import process is.

The important thing is that the finished Reptile Relief setup should give you separate roughing and finishing toolpaths before you export the G-code.
