Precise cutting coordinates

[loranger]

Hello,

I have to cut a lot of parts from MDF sheets.
I try to optimize my cuts to limit my waste and I use deepnest which provides almost full sheets to cut.

Now I have another dilemma: How can I place my sheets (which have little or no margin) so that the laser does not go out of the working area?
Camera shot gives good results if it’s perfectly calibrated, but it’s not enough, there are still a few millimeters difference and in my case I don’t have those millimeters since my cuts goes from edge to edge.

What solutions do you use to have as much precision when laying as when cutting?

You can use my repeatable laser origin guide.

Accurate, Repeatable Laser Guide

My rotary guide (found here) seemed to be well received, so I’m going to move onto the laser. This guide will be a bit shorter, as it’s not too involved, but is mostly to help increase repeatability, accuracy, and quality of your laser projects. Likely any machinist will say a repeatable, accurate origin is a key component in quality production. You gotta know exactly where you start to know where you’re gonna end right? I know the snapmaker method is just eyeball it, be it with a mark and lini…

There’s a sticky at the top of the 2.0 section with a bunch of guides. My whole goal is precision.
