View Full Version : Accuracy in Designer software...

This is a continuation of my previous post about straight lines/precision...

Sure, using the snap/grid would be nice, but apparently no one who designed this software has ever seen a real tape measure. In the "Snap to Grid" dialog box, you can't enter anything past 3 decimal places. 1/16" = .1875, NOT .187.

What would I do if I had this machine and I wanted to cut blocks that are 2-5/16" square? It wouldn't be accurate to that precise number.

First stop and consider the advertised resolution of the machine, between 0.005" - 0.010" inches in raster mode (from FAQ page), then consider the properties of wood itself; it moves quite a bit with temperature and humidity.

Some experimentation has shown that the software has a resolution of 1/128" on both raster and vector objects.

Also consider that nobody, can read a "real tape measure" within .0005

A human hair is approx .003 thick. You would be splitting a hair 6 times to see the resolution you are concerned about. Round your fractional number up or down to a 3 place decimal, and I am sure you will not know the difference.

Most average quality industrial CNC machines are rated at .0005 over full stroke when they are new, usually with a .0002 repeatability. To expect a wood working machine to do that is not realistic, nor necessary.

Keepin' it real.....:rolleyes:

Guess what you'd have to do??? Move up in quality and spend about $10,000 for a Shop-Bot. Just kidding, of course, but it won't compete with the big CNC machine yet. Give it another year or so. Pam

The XY resolution within Designer, .mpc files, and the compiled projects stored on the flash card are limited to 1/128". The depth resolution within Designer is also generally limited to 1/128". Though, the depth resolution for raster patterns when compiled and stored on the flash card is roughly 0.0005" (closer to 0.000488").
