Z cutting deeper the more time goes by ???

If you want to send me the g code I can take a look

Thanks I’ll try and upload it.

Heres the gcode from the area that suddenly went deep.
thanks

[Mr.Chips]

Heres the entire TXT code

received a exceeds system size limit , dont know how to send it, sorry

[Mr.Chips]

I think this is the file before converting
OK cant send CRV
sorry

When I said I ran it again, was kind of misleading.
I opened the file and copied a portion of the vectors/text where it went bad plus a little more then pasted it into a new file, then regenerating the Vcarve and converting that new portion and ran it. There’s probally nothing wrong with the artwork/vector file.

Would you suggest I start a new forum posting stating that I have a problem that is associated with the code generated and would like someone to take a look and see if the code looks OK?

Thanks Gary for all you hard work and suggestions I appreciate it.

Have you tried taking your artwork and creating a new G-Code cut file from it? I'm talking about taking the whole artwork file, and converting it, just like you did the first time. Once you've generated a new G-Code file, you can compare the old with the new and see if there are any differences. I'd pay especially close attention to the area where you keep getting the screw ups.

I've heard stories of Mach 3 having some mysterious glitches. I've experienced a couple myself, although nothing like yours. It's one of the reasons, along with the fact they stopped supporting it, that caused me to migrate to Mach4. That's not much help, because I don't have any suggestions to go with the observations.

If Jfrahm can't help you, I believe that starting a new new thread is a good idea. Actually, you might start 3 of them, 2 in CNC Zone and one in the Mach forum. In the Zone, I'd start another thread on the Vectric forum and another in the DIY CNC Router Table Machines forum. That way, you are covering all bases. One covers a possible Mach 3 issue, another covers a possible Vectric issue, and the 3rd covers the mechanical.

Thanks Gary, already got another one in the works, can’t hurt.

Thanks for the suggestion about posting on different forums

Would probably have to break it into smaller files and send in pieces. So my second question would be what do you do after it cuts to deep do you have to retouch of the tool length, which would be something mechanical or lost steps or just send the z to a home position and start over and its good which would make me think a software/ g code issue. Also does your set have tool offsets or do you just set one tool for a job and set the top of the part has zero.

[Mr.Chips]

Thanks, I’m scanning the JPG file and starting over..

Download 7zip and zip the file.


As for your problem. Look in your Mach3 tool table, and make sure all the tool lengths are set to 0.

[Mr.Chips]

looked at where you edit and select the tool and didnt see any tool set zero. maybe not in tool tale.

but the file starts out ok i pause it and use MDI and do a Z0 and its file, let the file run longer and do the same thing and the tool goes 0.200' into the material but the XYZ displays the Z as000

[Mr.Chips]

i think i compressed the file you might be able to open it.

[ger21]

Config > Tool Table.

Make sure the Height Column has all zeroes in it.

[Mr.Chips]

where is the Height Column

[ger21]

In the Tool Table

[Mr.Chips]

dont see what you are refering to heres a photo, that might clear things up.

[ger21]

In Mach3

[Mr.Chips]

here's a very small file and it is acting the same way.
material zeroed at surface.

it cuts deep and when it finishes the run i use MDI and say z0 and the vbit goes 0.200" into the surface.

if someone could run this file and see how it runs it would be nice to know and possibly clear up some things.

Thanks

In Mach3

that is from mach 3

Look again. The screen shot above is from your Vectric product, not Mach3. What follows is a screen print of the Mach3 Tool Table.
