Cutting issues...Cutting fine then cuts too deep for no reason?

The XY speeds are ok. And It looks like the Z moves were already ok. The one that I saw that was dangerous was just that first one.

make sure the x-y gantry isn’t too tight and causing the z axis to bind.

whole machine moves nice and cleanly. I use the jog buttons on repeiter host and it moves all around the table and up and down.

Hello Jeff,

I went back into Aspire and Reptier host and set them both to mm/min.

Then I went back and updated the file and resaved it.

Then when I loaded the G code into RH I scrolled through the code in the editor.

I you look at the picture above, Line 1088 and 1089, repeat themselves about 15+ times so far and I am only slightly into the code.

If I try and delete the lines it leaves an empty line. Will that affect the code or do I need the lines in there?

As you can see in lines 1090 and 1091 the F speeds go back to being correct.

It is like this all through the code, like I said I have seen it 15+ times and I am barely into the code.

I don’t think that’s the problem. Those are goofy (because they define F more than once), but I can’t see how that would affect your Z. The next Z move defines a F254, which is fine.

ok I am running a test cut of the resaved file in a piece of foam board now.
I will like you know how it goes

thank you for all the help

it still looks like it is too deep.

I lowered it it only .045" deep, that should be about 3/64" deep.
still looks like about an 1/8".
But it is all uniform in depth …so far

It cut the whole file complete with out any issues.

Thank you.

I have one last question.
I am using a 1/8" 20 degree V bit, cutting the script letters.
What should the depth be, I am still loosing the inside of the "e, o, a, d, b, p, R, B, etc.

Could you post a Pic of the cut, to show us what you mean by losing the inside of the letters?

Something is goofy with that dialect of g-code. There is a Marlin postprocessor for Aspire. Are you using that?

Here are some pics. even one of my micrometer.
I started with the depth setting of .075, thought that would be nice.
lowered it to .045 and still to deep.
the pics are at .045" deep.

I think so. Have been using it for a while.

says;
marlin (mm) (*.gcode)

If you do that type of cut with a V Bit it will vary the depth for you and keep real sharp corners.

But the whole cut, ( all the words are too deep), as in the pictures all the inside of the letters are missing.

Two solutions/issues. Firmware or CAM.

Test the machine when you say move up 30mm does it move exactly 30mm? If so you have bad CAM or CAM Post Processor. If you are still using Aspire all sorts of people are having issues with the ebay version and my PP, I suggest estlcam.
