The first attempt at cutting a 3D model turned out horrible. The design looked like it was melted.
I was told to purchase a UC100, which I did.
The original post processor that I used was Mach 2/3 Arcs(inch)(*.txt). I switched to USBCNC (INCH) (*.nc).
My initial settings in Mach 4 for my machine were 3200 which moved all axis 1 inch exactly.
Through the Mach 3 that was previously set up on the machine, the auto stated 3200, 120. I set for 3200, 200. This caused my project to be eaten away during the rough pass. I slowed it down to 120 and I got a somewhat descent model.
There is still something wrong! Two issues.
First, When I complete the finish mode with a 1/16 tapered mill, the project turns out almost perfect, but there are several deep initial gouges at the bottom of the project, not clean and the same at the top of the project when completed. Within the design there are several stray gouges deep into the wood and across several of the arcs in the design.
Please help me determine what settings or issues I am having.
Second issue, After I create a new project, select Job type as single sided, Job size x,y,z, Material Surface, XY Datum lower left, High(3 x Slower) Modeling Resolution, and select OK. I import component/ 3D model, .stl file, which looks great!
I choose Model size Y 8.6827, X 6.6577, Z .6754 inches, and Zero Plane slider to .3918, which puts the top edge of the project to the surface of the material and select OK. When I look at the project in the Z axis face on, the majority of the design is missing. looks like it falls below the material surface and will not be cut away during production.
The only way to get the model to show the entire design is to bring the slider all the way to the bottom, which brings most of the design out and above the surface of the wood. I have tried cutting both ways, the design will cut exactly what is shown when brought to the surface, which leaves the remaining part of the design below the material, and if brought up out of the material so that it can be seen in the 3D view, then the CNC cuts the design all of the way through the wood after about the third pass, which is not how it is shown in V-carve.
Please help. I can send pics if needed to show what the design looks like and what it is doing to the actual wood. I feel that some of my settings in Mach 4 might not be correct, that there might be a setting that the UC100 is missing, or that I need to choose a different post processor? The design works perfect on an alternate machine running Aspire, so there is something not quite right with my machine.
