# Cube Pro Bondtech

We weren't sure we could pull this off so we didn't have step by step documentation of the build process. This page will be updated soon with all the 3D models, wiring instructions and Marlin 2.1 configuration so that you can perform the mod yourself.

## Gantry Modifications

**First Attempt:** Original gantry. This solution was less than ideal since Bondtech Extruder doesn't fit between the original linear bearing blocks. We designed a spacer to go between the extruder and hot end.

**Third Attempt:** LM12UU bearings are mounted on half bearing blocks and secured with zip ties. One LM12UU in front and two at the back. The more compact design allows for a more powerful blower and a closer fitment for the BL Touch bed leveling sensor. This design also increased the total build space to 295mm x 280mm x 215mm from the stock 285mm x 270mm x 230mm. The slight loss of z height was caused by dropping the head between the rails.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.cherokeemakerspace.org/index/wiki/3d/mods/cube-pro-bondtech.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
