Cutter accuracy

[magicniner]

I would like to measure travel over a longer distance but I'm limited by the measuring tools I have available (Mitutoyo 200mm vernier caliper, in this case).

Get a good brand and quality steel rule, use your digital caliper to make a little brass vernier and you can read to a 0.1mm or better over the length of the rule.
Measure at 20 degrees C though ;-)
