Hello, I seem to have a problem with my system. I am using 2D vectric software along with Mach 3. If I set up a project to do one cut countinuously it works fine, But when I set up a project that needs multiple cuts the cutter starts to go deeper and deeper into the material and I have the max cutting depth set to .0625 and it still does this, What am i doing wrong?

Thank you

Can you post a picture of what the issue is? Where did your geometry come from? CAD, PDF, jpg, bmp? Just reading your post as it is it sounds like that there are mulitiple peices of geometry on top of one another....just a guess. Provide us with more information and then we can go from there.

it is a sign of a notary stamp that has numerous little rectangles that circle the stamps outer and inner parts and they lay next to each other and not on top of each other, and what is happening is the machine starts out fine but as it moves from one to the next it slowly goes deeper and deeper, The max cut depth is set for .0625 the material is set for .375 and the passover depth is set for .0625. What am I doing wrong here? Thanks'

It sounds like you have the the z reversed in either your cut or your image.
A pic is worth a thousand words and a little crv file would help also...

edit: Check your tool for it's max cut depth and it's passover depth also as this may override your tool path

I tried uploading the file to this site and where it went I have no Idea, so if you have a regular e-mail address I can send it to you.

you can use z axis inhibet on mach3 blue screen to set max depth

You could do that but the better answer is to fix the code or at least get the z going the way it should.
On another note, are all of your axis calibrated between your machine and Mach? Assuming that you are running a DIY machine?
Gathering more information instead of guessing and I will PM my email address to you.

[jzak3]

Yes it is a DIY machine and usually works pretty good but for some reason when I need multi cuts it seems to do this? I also have an e-mail sent to vectric about this. Thanks

[DeadTom]

Ok let's back up a bit, please define "one-cut continuously" and "multiple cuts".
I have just looked at your file and it ran no problem (virtually, that is) with the 60^ v-bit.

What i mean is if i cut out a circle out of a peice fo material it will work fine, or cut out a pocket but if I need for instance the pattern I gave you, the bit will slowly go deeper each time as it moves to each cut.

[ger21]

It could be your Z axis losing steps each time it retracts, causing successive cuts to get deeper.

[jzak3]

At this time it could be anything, I think it maybe the work table? question for you, How do I set up that auto zero deal you have in mach 3 and how is it wired in? Thanks'

[ger21]

The plates are wired to an input pin and 5V with a pullup resistor, and the router spindle is connected to ground to close the circuit when the bit touches the plate. The input pin is assigned to the Probe input in Mach3.
Big Tex has a thread on his version.

[jzak3]

you wouldn't happen to have a wiring diagram for that would you? and what size resistor? and if you do I hope you don't mind sending me a copy.

Thanks'

Well, I found my problem. It appears that I had to group all the vectors together and re draw the tool path and now works fine? And now I have a couple of new questions. (1) I wired in the auto zeroing tool to my TB6560 control board and it moves down to touch the copper plate (0.64") thickness and then retracts up to 1" above the material and when I press go to Z it moves down to the top of the material but does not touch it. What am I doing wrong? (2) Also I would like to drill a series of holes in my sacrifical board and tap them so that I may use them to hold down material,but I am having a problem wth the vectric peck drilling, What can I do.?

Thank you.

What is the code in your auto zero macro?

What is the problem you're having?

If your plate is .64 thick, then it should be:
Call SetDRO( 2, .64 )

[jzak3]

yes it is set to that I forgot to send you the edited one I used

[ger21]

Try this:
