Very nice. Praveen has done a good job. I would like to give a little idea. I think it would be better if you could use another stepper motor instead of the free wheel. It could otherwise be inaccurate when the pen is loaded with some friction. Just an idea. I know time has already become a problem.

How about line bearings without an other stepper :?:

As long as it can handle the friction of the pen, technically a bearing is okay. However in practical terms, you will have to do some additional work to get it to work. Since this topic is very long, please start a new topic for other questions.
