Add more functions to 3d printers is a topic in my recent project. I have added a drag knife to it but the result is not as good as I expected. Some reason I already know. Mostly it is caused by the linear motion ball bearing is not smooth enough since I chose a cheap one to test. I change it to a simple tube alignment structure restricted by two pairs of ball plunger. Now it is much better than last time. Even the small text can be cut precisely.
It uses the same skeleton box as I uploaded before. The clip and screws are also the same as the multi-pen plotter.
The original f3d file is also added. You can modify it to fit your 3d printer if it is necessary.
If you like my design or my design idea or concept, please subscribe to my channel and watch longer as you can. It will help me a lot. Thanks a lot.
