<p>I did a remix of purge bucket. Backet isn't clogging now.<br/> <figure class="media"> <oembed url="https://youtu.be/EdnXuI9g5_g"></oembed> </figure> </p> <h3>Print instructions</h3><p>I modified the gcode a bit. I don't know why, but retraction doesn't work on the first tool change. Another object needs to be printed.
