For a long time I did not undertake the manufacture of auto-feed. There are about as many doubts about its convenient design as about the manufacture of a protective self-tensioning curtain, for which there is still no video or the most finished design. It seems that both of them are far from new, but when I saw the finished designs, I didn’t understand what exactly I needed.
Therefore, I decided to look closely already in the course of work and in practice. This method is not the fastest and certainly not advantageous, compared with the preliminary calculation. But visually and tactilely felt, and since an accurate calculation does not help, then the hands will immediately understand whether the design is convenient.
The main point of autofeed in my opinion is simple: to ensure smooth and slow movement of the table.
Submission is really needed when it is necessary to serve accurately and for a long time. You can quickly apply with your hands, it is not difficult and does not take long. Therefore, I devoted a lot of time to testing stepper motors in this environment.
