Reverse engineering / reverse maslow 'tracer'

I just had the idea of a manual ‘edge tracer’ where 2 rotary encoders and an arduino are used to trace around the edge of an object to feed coordinated into a reverse maslow and spit out an svg that in turn can be copied on the maslow.

A lowtech approach to copy a design. For woodworkers who like to use machines but hate to use computers.


A bit like using a copy ring on a router, but then only trace the design once, save the outline, and copy the part whenever it’s needed.

How to become a modern day woodworking pirate…



That’s an awesome idea!

the limit is that you would be limited to measuring things that the sled can
ride on. although you could make side rails and extend the sled horizontally
(this is MUCH easier with triangular kinematics)

Whatever is most simple. :slight_smile:

I came to this from the perspective to calibrate the machine…

  • Make a rough calibration
  • let the machine drill the triangle-hole-grid that i mentioned in another tread
  • use a rotary encoder based kinda thing to measure the hole positions
  • use the measured hole positions to make a more accurate calibration.

repeat this for even more precision…

Then this idea popped into mind and in my exitement i forgot to tell how i got there. :smiley:
