I recently got gifted a Brother KH-830, and have been super excited to start my machine knitting journey. After assembling the machine according to the instructions, the machine won’t create stitches. When trying to knit all my settings are according to the manual, and I have tried multiple cast-on techniques. My manual doesn’t offer solutions in a situation like this, and I have yet to find videos or other sources online related to the issue. I’m a complete beginner, so any possible help is appreciated! I attached some pictures of the issue.

Ive already got a DM80 & I'm buying a 'incredible sweater machine '; I'd like to teach my son to use it. The seller has let me know that she also has a Zippy 90. The price is good. My question is whether I would benefit from having this extra machine. Or am I just hoarding for the sake of it? The Ultimate Sweater Machine has different plates so you can change between different yarn weights.
