Item 1 i'm not sure what you are talking about the cut looking like a "U" a picture would help.Yes, i know about that. I am learning tho. Vectric videos are confusing to me. Most youtube are too fast .
I am VERY old school. That's the problem. That's exactly what I'm trying. I figured out the height issue. Model height and wood thickness..125 +.625= .75 inches.
2 issues. 1 along outer edge profile cut shows an edge. Like a u.
2. How do I make it (from bottom up) 1/4 in,start of contour up to top face? Like your piece has three layers bottom,center,face.
Darn - Now you got me confused.Item 1 i'm not sure what you are talking about the cut looking like a "U" a picture would help.
Item 2 decide how you want it to look and create the model to fit the measurements you want. My file was based on a material thickness of 0.375". I created the vector outline for the plaque. I decided to leave 0.03" for the finish pass of the model so 0.375 - 0.03 = 0.345. Then I wanted to make 3 equal layers, the base, the first lift and the second lift so I divided the 0.345 by 3 which gave me 0.115 for each layer. Then I created a profile with an arch having a radius of 0.115, and another arch above that one with a radius of 0.115 and a line down 0.230 to use for the 2 rail sweep. Then I offset my profile vector 0.230 to use for the second rail. Then I did my 2 rail sweep using the outline vector and the offset vector for the rails and used the profile for the cross section. I connected the profile to all the rail nodes so it would render correctly by using a right click on the cross section to get the drop down menu. I used the sweep between and fill center options to create the model. Went to Material Setup on the Toolpath Menu and set the model 0.03 down from the top. Then ran roughing, finish and cutout toolpaths. That is the preview I posted.
So you used a ogee profile and don't know what size it is. in the two rail sweep you can set the thickness of the model and that takes care of the profile height and the width between the rails takes care of the profile width. If you don't scale to exact height then the model will be as thick as the profile.The "u" shape is not cutting past the edge I guess(from what I just read).
OK, I got material thickness. I don't get equal layers tho.(I understand bottom, lower arc, upper arc) line down .230?
I made my outline vector, offset vector .25, I pasted a ogee profile, selected outer-inner vector-profile, apply.
Remember you can change the height of the model in the Component Properties menu. Also your model does not have to be the full thickness of the material. In my design file I had a material thickness of 0.375 but I had my model thickness set as 0.230 and had the model 0.03 down from the top of the material. That leaves 0.115 under the bottom of the model that will not be machined with a roughing or finish past so any tabs you add are safe from being cut by roughing and finish. Your cutout toolpath will cut the rest of the plaque and leave any tabs you add.In the vectric tutorial he said dont worry about the size of profile. But I did make it 1 inch.
In that pic ,I want base to be .25 and profile .5 making it all .75. In mine it's .5 base or more probably .65
What software were you using to output the gcode to cut this or are you talking about the preview in the software?Played around today.I think I had model set at .5 inch and material at .75. Did rough cut and it took it all down. Then changed bit and did finish. It was about 1/8 inch above the rough cut.I set z zero on top of material.
Back to drawing board and I see it rough cuts over whole model. I set model boundary.how do I get it to only rough/finish the contoured edge?
I've been watching videos all day,12 so far. Started from beginners #1....my eyes are bleeding......
Oh and Tinkerbell, I tried 60 degree 1/4 inch v groove at .02. Barely cut in but still a lot of tearout or overlap.ready to try a Finnish nail.
