Hi, I need help wiring the EOT knife tool to the 4th axis driver. You mentioned making separate box with switches. Can you please show me how that looks for both, the tangential and oscillating wiring. Thanks a bunch! ---

```auto ``` 11 years ago, I redesigned my cutting kit. I used a combination of mach3 and sheetcam tng, which has a postprocessor for a tangential knife. I tweaked it a bit, replacing port A with port C. I spent a long time searching for options, but this one turned out to be the best.

I want an OTK for my AVID router badly. The EOT-3 seems to be not available right now so does anyone know anything about the Stepcraft OTK-3? I don’t think they support 3rd party machines, so I would be on my own. But the price is right at $500, so I might be tempted to give it a try even though my technical level is below expert. I’m looking for opinions, so tell me what you think. Thanks in advance. ---

I’m going for it. Just bought an EOT-4 from Damen CNC in Holland. ---

Interested in how it goes for you. Keep me posted! I would love to create my own custom packaging out of cardboard sheets and custom foam inserts using an oscillating knife and a creasing wheel. ---

I will start a new thread with progress on the build. Also cries for assistance. [Previous page](https://forum.avidcnc.com/t/ecocam-tangential-knife-post-for-vcarve-pro/3060.md?page=1)
