Hey there,

Say I have a GCode that I received from a friend that is a 3d file of a horse from MeshCam.

It's quite large at around 8" X 16" with a Z depth of about an inch. If I use the scale factor on the program run screen next to each of the DRO's, setting it to .500,  that makes it half of the original overall size, I get that part.

Now, for the stupid question, does that automatically make the toolpath smaller as well? In other words, for the finish pass, the cutter used is .125 so if I'm cutting that in half, I should be using a 1/16th cutter now, correct?

Thanks,
Dave

i have used scaling a bit and found it to be iffy at best for my level of work at anything over 1.15 or smaller than 0.85. since the path was written for a specific size tip you would have to alter tip size accordingly. some issues like paths written for tapered cutters cause grief because as the scaling gets smaller the included angle of the cutter has to as well or you WILL clip higher parts and straight wall sections.

i only use it as a quick way to scale rings in X for more width on plain rotary jobs without having to redraw and repath an entire ring.

Thanks, Chris, I believe your level of work and need for close tolerances is way above this Code, but thanks for weighing in and it's definitely good food for thought if anything intricate comes along.

Scaling in mach 3 question where i have more plans to change information for the topic. I want to bring something better and can make custom essays uk which is really important to keep them and also want to change all of these style for question.
