As the pictures show. I am having an inconsistency in what seems to be the X-Axis. I have tried lowering my step over but it remained. Any help is appreciated.

A round end mill will not create a flat bottom unless stepover is reduced to 10% or less ---

Try a combination of a round nose for the edge and a straight bit for the bottom. I guess Easel has a two step program possibility ( I don’t use easel). If I were doing it, I’d make two programs, one does the rounded perimeter, and the other cleans it out with a straight bit. There are also bowl bits with rounded edges and a flat bottom. > **[CMT 3/4" Dia.

I am using a similar bowl bit. it is flat on the bottom. what program do you use instead? I will look into two step process. Thank you. ---

This is the bowl/tray bit I am using.[https://www.amazon.com/Whiteside-Router-Bits-1372-Diameter/dp/B000K2ADLY/ref=sr\_1\_1?keywords=Whiteside+Router+Bits+1372+Bowl+and+Tray+Bit+with+1%2F4-Inch+Radius&qid=1559319039&s=hi&sr=1-1](https://www.amazon.com/Whiteside-Router-Bits-1372-Diameter/dp/B000K2ADLY/ref=sr_1_1?keywords=Whiteside+Router+Bits+1372+Bowl+and+Tray+Bit+with+1%2F4-Inch+Radius&qid=1559319039&s=hi&sr=1-1) ---

I’m using a combination of Rhino and CamBam for 2d work, and Rhino and Meshcam for 3d work. Any Cad program that can save a DXF file will work with CamBam, it just happens that Rhino was one of the popular 3D programs a decade ago when I started this stuff. If you are using a bowl bit already then maybe it’s a matter of adjusting your stepover and adjusting the eccentric nuts a bit. ---

Based on the spec in the description you would need to use step over of less than 33% and then the bottom should be flat. ---

Where in the description would this be found? I don’t understand how you figured that out? ---

Description says 3/4 wide with 1/4 radius. That means that only 1/4 in the center is flat. That is 1/3 or 33.3333% Any step over beyond that 33.333% will have the radius on other we’re edge of bit leaving the scallops you have shown. Just some simple math. ---

You need a stepover of .25" or less with that particular bit. The red line is the resultant cut. A stepover greater than .25 leaves a scallop. ![stepover](https://yyz1.discourse-cdn.com/flex009/images/transparent.png) ---

Thank you to everyone that has responded and answered. I have rebuilt the table it was on and made a single solid layer to help with leveling. I am going to go through everything tomorrow and check for square/ check tightness. Again, thanks all. ---
