### 4.2 Parameters

#### **4.2.1 Projection Direction**

Six model directions are available—front, back, left, right, up, and down. For example, if you select **front** , you will see the front view of the model. Likewise, select **back** , and you will see the back view.

![Screen_Shot_2021-02-04_at_4.49.00_PM.png](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/4/4d8d258a3a10aec5322bb9fe9886d24c6c3b05ac.png)

#### **4.2.2 Carving Tool**

The Straight Groove V-bit: Features a long and sharp carving edge, penetrating deep into materials and rendering high-precision creations. The extended flutes on both sides create a larger area of engagement, providing a superior carving than single flute bits. It can also clear sawdust, eliminating clogging and reducing wear and tear.

## 5. File Transfer

You can click either **Load G-code to Workspace** or **Export G-code to File** to transfer the G-code file. What media you transfer to, Touchscreen or Luban, determines how you set the work origin and start carving. The Touchscreen instructs you to fix the material, set the work origin, and attach the Tailstock. So if you are a novice, we recommend you transfer the file to Touchscreen. If you are not, Luban is an alternative.

## Tips and Tricks

### Bit Assistant

#### **How It Works: Bit Assistant**

If you carve something complex using more than one CNC bit, Bit Assistant can simplify the procedures of resetting work origin. Normally, if you change a CNC bit, you have to reset the work origin. Whereas, under the guidance of Bit Assistant, what you need to do is simply touching the same material spot with two bits. The touching step measures the length difference between the two bits. With the difference measured, the machine can calculate the Z-axis offset and work out the new work origin, without changing the X, Y, and B origins.

#### **① Generate Multiple G-code Files**

First, generate multiple G-code files and transfer them to Touchscreen. In each G-code, choose the specific bit you want to use.

**Tip** : For instructions on generating and transferring G-code, see _**[4. Generate the G-code File](https://support.snapmaker.com/hc/en-us/articles/1500001930021-Rotary-Module-CNC-Carving-V1-0-0#h_01EZBYRQGVAHWRREFBGFFQ2MZY)**_ and [_ **5.1 Transfer the G-code to Touchscreen** _](https://support.snapmaker.com/hc/en-us/articles/1500001930021-Rotary-Module-CNC-Carving-V1-0-0#h_01EXQZSNMBBCFKCQWW8C51M6EB).

#### **② Bit Assistant**

When the first G-code file is finished, tap **Complete**. Do not remove the first CNC bit yet.

**a. Manipulate the First Bit to Touch the Material**

Tap **Toolbox** in APP List, and select **Bit Assistant**. Read on-screen instructions on how to change a bit and reset the work origin.

**b. Replace the First Bit with a New One**

Make sure the CNC module is lifted to enough height so that you can change the bit. Remove the first CNC bit using open-end wrenches, and replace it with a new one.

 ![--.png](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/c/c30591d33e72518bf20df2d9dcfedebea665b458.png)

### How to Use the 3-jaw Chuck

The 3-jaw Chuck consists of three reversible jaws, and each can be installed in either way. The way you install the jaws affects how the Chuck clamps materials. In this section, you will learn how to install and use the jaws, lending more fun to your making journey.

![blobid2.png](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/e/ed30cfcbe4c45c77143fa73d4eab354bb11439e4.png) Caution the sharp jaws during installation and use.

#### **① How to Install the Jaws**

By default, the jaws are installed for inward-clamping. If you want to reinstall it into outward-clamping, disengage the three jaws first, and see _ **b. Outward-clamping** _ .

#### **② How to Use the Chuck**

Inward-clamping is designed primarily for clamping the external surface of workpieces, and outward-clamping basically for internal surfaces. In other words, outward-clamping can clamp both solid and hollow workpieces, but inward-clamping is solely for solid ones.

 ![Screen_Shot_2021-03-30_at_3.19.58_PM.png](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/6/69104dd57c6e3c5ae77fc0f0544d41f65bc8af91.jpeg)

### How to Glue the Nut into the CNC Platform

If the nut is screwed out of the CNC Carving Platform, glue it back in the following steps.

![blobid2.png](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/e/ed30cfcbe4c45c77143fa73d4eab354bb11439e4.png) Before use, wear protective gloves to prevent contact with the toxic AB glue. Wear our provided mask to avoid inhaling the pungent smell of the glue. Do not misuse the A glue lid on the B one.

① Clear the sawdust on the nut.

 ![Screen_Shot_2021-03-30_at_3.30.03_PM.png](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/4/4f146672f76c154b0b08a6f2ac0954227c3a610c.jpeg)

② Squeeze out the A glue and B glue in a 1:1 proportion.

 ![Screen_Shot_2021-03-30_at_3.31.15_PM.png](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/4/44bd43ed7d517f42896bc09e18e5f95173119418.jpeg)

③ Mix the A glue with the B glue using the red mixing stick, and stir them evenly.

 ![Screen_Shot_2021-03-30_at_3.32.42_PM.png](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/c/c213affb5801e11296b81833e6ee609aa064f602.jpeg)

④ Tweeze the nut out, and apply the mixed glue to the screw thread of the bottom of the nut.

 ![Screen_Shot_2021-03-30_at_3.34.37_PM.png](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/c/cd0a58fb53e6df9a61525034798b73f0f4783be9.jpeg)

⑤ Tweeze the nut back into the hole of the CNC Carving Platform, and press it for a while.

 ![Screen_Shot_2021-03-30_at_3.36.01_PM.png](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/e/e1d85544fef388f55184a8a8c5c303290487cb64.jpeg)

⑥ Wait at least 24 hours to ensure that the mixed glue is cured before reuse.
