OK... Thank you. Currently, I am using a 6.4 mm 60 degree bit with a 0.5mm tip. The current max crossover is set to 0.7. I will change it to 7 as your example shows and see how that works.

Thank you again.

Thank you David but that is not the issue. There are no gaps in the hatch that should not be there. Maybe I didn't explain it correctly. Sorry, my fault. The issue is the Z axis, after making a hatch line, raises 2.5 mm then moves over to start the next line, then the Z moved back down to start the next line, then repeats for every hatch line.

My question is why does the Z have to raise up then move over for the next line? It should just finish the line and move over to start the next line. I think it is unnecessary for the Z to move up, then back down. What I was hoping to learn is if there is a way to set milling process to NOT raise then lower the Z axis when it moved to the next line to mill?

that did the trick. One more question tho.

When my CNC is milling the hatch portion, the Z axis raises, moves over to start the next line, then lowers again. Seems like an unnecessary move and a lot of extra wear on the Z. Is there a setting I can change that will stop Z from retracting but instead just move over and continue milling?

Thank you Dave. Sure looks easy when your shown how to do it.

Here is an image of what it is doing.

In the attached image, I intend to fill in the object with a hatch. Unfortunately the hatch fills in everything and I want the 3 swoops to NOT fill in. My thought is because that line is there on all three swoops. See arrow pointing to one example.

I cannot figure out how to remove that line. I have exploded the polyline for the whole object but then CB will let me delete a portion but not the area I need. I then tried deleting a portion and re-drawing the line but CB won't let me connect it to the right spots.

I would like the hatch to fill in everywhere EXCEPT these three areas.
Please advise.

Thank you
Bill

Yup ... It worked! I used a jpg file so that is why it is squiggly, but some fine tuning of bit size etc. and I think we can call this a win!

Thank you all again for your help with this.

OMG! I have to try this. Thank you. Between this and David's explanation, this might just do the trick!

I went through the steps and it sure looks like it will work. UCCNC seems to  like it. It shows the areas filled in. Looking forward to trying this out on the CNC tomorrow.

Thank you so much.
Bill

Hi Bill

Actually, I did find software that will make the file work the way I want it to but CB does not like .svg files.
Then use that software, it's a long and tedious process in CB.
Dave

Ok...let me explain what I meant by finding the software that can do this. I left it kind of vague.

The software I was referring to is Easel. It accepts .svg files that I convert from that .jpg of the dog using Inkscape.
I have attached a screen shot of what this file looks like after everything is set up. The problem with Easel is that when I download the g-code and try to run it on my CNC, it starts to draw the image to a size that is smaller than a pencil eraser. I have no idea why it does this! I thought g-code was g-code.

So, I got on the forum for Inkscape to see if there is another way. In a nutshell, I cannot get Inkscape to give BOTH the lines AND the filled in areas.

So then I looked at Gimp. I could not find out how to do it there either. I then tried Blender. Again, no luck there.

Looks like I will have to try what David suggested. Seems to be the easiest route.

Thank you David. I will give this a try.

Thanks dh42, I tried the hatch plugin but as was mentioned earlier, there has to be a closed loop for it to work. Lets take the nose tip for example. I tried to draw a line in 3 spots to get it to close up. I could not get it to work. I think that once a closed loop is obtained, the hatch plugin could make this work.

Actually, I did find software that will make the file work the way I want it to but CB does not like .svg files.

I am interested in what you have used to hold the sharpie in your machine is it custom made? 'Builds with Brian' also goes through several methods for 'holding' a range of drawing tools (mostly sharpies) that you might find interesting too.

Thingiverse.com and did a search for CNC pen holder. Yes, I have seen builds with Brian's holders but since I also have a 3d printer, I figured I would just print one!

taking a very close look at the dxf file, I can see that when it was converted to .dxf, it took the thick black lines on the original drawing and made double lines. The way I see it, and I may be way off base here, is I would need to close the loops in the areas I want shaded, or make a MOP for all the areas that are double lined and shade those areas.

Either case, I tried closing off areas with a line or an arc and had little luck joining everything together. I played with it for awhile and came to the conclusion there has got to be a better way.

I would be thrilled to have this used as a tutorial for others. I would even volunteer to write these steps up from start to finish so everyone can benefit. I would really like to figure out first how to re-create the infill just like the original picture has first.

Success!!!!! Thank you Eddy. although I'm not sure why it didn't work for me as I used the same MOP with almost the same settings (depth increments and target depths were set to 1 and -1 respectively) and plane was set at 3 instead of 10 but I am not sure either of those settings are critical to it not working.

Maybe downloading your file Eddy, showed MY file what it was supposed to do and then it did it!

HOWEVER... just one more detail. If you notice in the original picture the eye brows, nose, mouth, etc are colored in. When converting the file to .dxf to import into CB, it creates the lines but does not "close" those areas so I can "pocket" and fill in those areas (or color them in with the sharpie).

I am not sure if this is outside of what CB is designed to do, but can anyone recommend how to get the file to work such that I can fill in those areas? If it is outside of what CB can do, can you recommend a software that can reproduce the image and still work with CB?

Please don't say Vectra Aspire or such software as I am not going to spend $2000 US per year for occasional use.

Thank you again all.
Bill
