Suggestions for testing accuracy and precision

Troubleshooting

Does anyone have suggestions or test files that they would recommend for testing accuracy and precision? I don’t have any specific concerns or issues with my Maslow. I’m just curious about testing it and having a point of reference on expectations as I get into larger projects.

I would also like to know what people have used. I guess I could see doing lots of parallel lines or nested L shapes along the edges and then some circles spread out and then some different depth square pockets here and there. You could measure distances between the edges of the L shapes, you could measure length and width of the circles, squareness of a rectangular array and then depths and square sizes.

This guy is doing inside and outside squares. Cut Test Samples Created by Philip1 — Files created to test cuts in different materials and with different bits.

For the Maslow speicifically I would want to do some large scale patterns because we have changing forces and theoretical accuracy near the edges and corners

This is interesting. Actually this could be a good test, one at every corner and one at center home. You would have to run it on multiple sheets, though, so a lot of waste. A pen adapter would probably be good for a first test, but running it under load would be necessary for any final results.

I have a couple grids at Index of /maslow a 1’ square grid with lines
every few inches, and one to cover the full 4x8 sheet

they don’t set the Z distance, just move the sled in the grid.

The idea was that you can use a pen or v-bit, set the Z height to just touch the
material and then execute the file and manually retract at the end of the cut.

I had a guess you had something hiding somewhere. Haha. This is perfect. Im doing some repairs on my machine but this is the first thing I’ll do once I’m done.

I’d run them first with no bit and the router not running, and only then do
something that you can then measure
