Silhouette machines can act up even when they are new. I wouldn’t just use the settings from the video since you are using a different paper type and I know that removable matte is a thinner paper so the settings I use are probably going to be too much for that paper. I recommend testing out other settings because what works for one person may not work for someone else. Every machine is different and sometimes every blade can be different and require different settings.
I would recommend adjusting the settings and also calibrating your machine as this sometimes helps reset the machine. There are several videos on YouTube on how to calibrate. And sometimes you just have to turn the machine off and walk away for a little bit. They have a mind of their own and sometimes you just have to put them in time out. Lol.
I hope this helps!
