My cutting depth keeps changing

[icncsigns]

Could someone take a look at my file and help me figure out why my cutting depth keeps changing. I can set it to .25 and it changes to double that. I'm a beginner and we are on a tight timeframe with a particular job. It has woodgrain texture to appear to be sandblasted with raised letters to the inside of that and a raised border around the outside. The file that i have attached isnt the actual job, but it has the same components.

Also the roughing profile keeps eating away all around the letter. I need my letterstroke to stay the same thickness.

Any comments would be greatly appreciated.
Thanks!

You forgot to attach the file!

what type of machine do you have, have you run a z test,, set a filr to cause the z to run in the air (3d) and see if it holds tollerance, could be step loss

What jim said...plus:

What type of toolpath are you generating (V-Carve, Pocket, Texture etc) ?
Its probably something straightforward.
Is the depth increase random or happening in the same place every time?
Did you check the G-Code file to see if there's an increased depth?

Did you zip the file before trying to upload?
Do a google search for 'Free File Sharing' and there should be somewhere you can upload it to.

I group the inside of the border along with the woodgrain bitmap(made into a component) along with the copy inside also.....then i do a roughing and finish profile with my depth set at .25. (It eats away some of my copy.)

I ungroup those items and select the copy only to do a normal profile toolpath around the outside with the depth set at .125 just for cleanup purposes.

I also do this to the inside of the border.

Then finally I do a profile toolpath for the outside cut around piece set at 1.01 for 1" material.

Jim,

I will pass that info along to the router tech. I design the part and tool it for routing so I wouldnt know a whole lot about that. But thanks, i will tell him!

Where are you setting the height for the toolpaths? The DOC for a relief toolpath is set automatically by the software dependant upon the model.....
