How can I pocket this logo. On the jpg file, all the black I would like to pocket like an 1/8" deep. How can I clean out most of the stuff with an 1/8" bit and then do the detail with a 1mm bit? Thanks.

HI chadrat6458
There are quite a few issues you have with this file.
1. when imported it's over seven hundred inches. I resized it to 7.453 inches.

2. If you look closely in the picture the saw blade teeth are a bit wonky (this is because it's from Inkscape or some svg program. I repaired these and they are now suitable to work with.

Have a look at this thread for more guidance http://www.cambam.co.uk/forum/index.php?topic=4935.0
There are many others just do a search for them here.

Thats all I could do for now as I must get back to the shop.
There are a few other members who are quite good at this and will help you, If you post a .CB file you will get
better answers to your questions.

I would like it 12" x 12". Can someone walk me through on how to set up the pocketing? Thanks.

Should I do a pocket using the 1/8" bit with a roughing clearance? What should I set the clearance to? Do a profile finishing mop using the 1mm bit?

Chadrat,

Do you already have  .CB file you've been trying?  And, have you tried the modified data file supplied by Dave?

In any case, it's usually easier for the members here to 'correct' an existing attempt, than to create a whole solution for you.

Please post what you have, and we'll all (willingly) look at it, and offer advice.

Yes, the goal is to engrave the black areas.

OK!  There's a start!

There are a lot of folks here who do that sort of work.  I'm betting you'll see some good advice soon.

I can't contribute much, because I do pretty-conventional 2.5D machining on metal.

Have a look at the attached cb file.

1. resized to 12"x12"
2. converted polylines to Regions. you need to read in the manual about 'Regions'
3.  You can see that a 0.125" dia tool is too big to fit into some of the spaces so it needs a 'Profile'  MOP to follow with a 0.04" dia tool

Hang on a minute  Huh
It started as a pocket, now it's engrave ?

Yes, the goal is to engrave the black areas.

Most likely a misunderstanding of the terms.

I agree, Eddy.  He hasn't yet understood the difference between 'pocketing' and 'engraving'.  I believe it's still a pocketing operation.

I for one would suggest for him to start with something very simple and be able to do this on his own, learn the terms, understand what Profile MOP does and how it differs from Pocket MOP, What is the purpose of a Region, How to engrave, etc..

@ chadrat6458

I have created a practice CB file for you to show how you go about engraving, pocketing and profiling those letters.
This way you can post this file back if you run in to trouble so anybody can help you more easily without guessing..
Good luck.

Not engrave.

I want to do what Eddy's cb file is doing. I will play around with it and see what I can do. Thanks.
