Hi Daniel
There can be an array of reasons that your cutter isn’t tracking far if it is used or old.
If it is brand new i would tend to blame it down to how "you" are loading it.
Manual accuracy is everything when trying to track any sort of distance so practice makes perfect.
different cutters, have different loading setups.
if the machine is used or old, various small things can make it track off.
Your pressure wheels for one. If the wheel is dusty or looks discolored etc its best to take some strong cleaning substance and give the wheels a good clean. simple things like a dirty wheel that’s built up grime can cause the machine to skew when tracking. also, if the machine has done a lot of work, the wheels can become flat or worn. this happening again reduces the traction of the media causing it to skew.
you could also check the pinch grit roller BAR. the knurled patter on the bar can be clogged with paper from a jam or continual use. use your wifes tooth brush, ahem… i mean use an old toothbrush and give the knurls of the bar a good clean. a little wire brush would be better.
again dependant on age of the machine. the knurled bar may be in two or more bits or use a knurled sleeve on a single bar. we had this years ago on one of our machines. tracking was poor and it came down to "play / movement" in the bar. all it needed was tightened. but created a skew and inaccurate cut text.
i could go on but these are some of the more simpler obvious reasons for tracking off, but there is a list of possibilities.
