New to CNC world

Postby ReidCDe65 » Wed Dec 12, 2018 12:39 pm

Hello all,
I jumped in the CNC world, bought the HD4 Extended. Got it set up [so I think] and decided to try it out with an out of the box project that Vetric has available. The only think I changed in the design was the material thickness (had some scrap material that was 11/16"). Recalculated the toolpaths, moved them to the thumbdrive. Turned on the HD4, set the starting point, set the Z with the touchplate. Selected the 1st toolpath and hit the go button. The machine went where it was supposed to and started cutting. It cut a micro version [Project dimensions are 9" X 8.5, the program/machine produced a 3/8" x 1/2"] of the project and I cant figure out why or where to go to adjust settings to produce the full sized version. Any help willl be greatly appreciated. Thanks all.

Sounds like VCarve may be set to mm instead of inches. 9mm x 8.5mm is about 3/8" x 3/8". Make sure your design file is using inches.

A quick note at some frequent misinformation I see in this forum: This is not a post-processor problem. You can choose either a mm or in. postprocessor and get the exact same size and result. The only difference is the unit the post-processor uses to generate g-code and it does the conversions itself.

Make sure you have the right post processor.

You can select either the inches or mm postprocessor and get the same result. Here's a simple experiment to prove that, in case you don't believe the documentation:

@Kavon @tonydude,
Thank you for the info, sorry for the late response, traveling for work.
It boiled down to selecting a different post processor.
I had saved the toolpaths using "G Code (inch) (*.tap)", I changed to "CNCShark-USB Arcs (inch) (*.tap)" and it worked like a champ.
As I stated in my post, I'm new to the CNC world and just about everything related to it is a new venture to me. I really appreciate your advice, I'm looking forward what the future has in store.

This is the part where I get to eat my words. ;)

I'm glad you got it figured out. tonydude was right in suspecting the post processor. I said the post processor didn't matter, but what I meant (and didn't say) was that which Shark post processor you used didn't matter. If you weren't using a Shark post-processor, then that would explain the problems.

You don't convert a dxf file! You just bring it into Vcarve and work with it there.
I usually just drag it from the desktop into my project.
