Elongated files


CNC Maker
Hi guys, I am using aspire 8.5. Outputting files to masso using ATC arcs mm.

If I draw a circle in Aspire, it shows on the Masso screen as a oval, but it cuts normally as per the Aspire file

sure to b something basic, any ideas.???

Hi @cnc-maker

The reason the circle looks like an oval is that you are using a wide screen monitor 16 x 9 to display Standard Definition screen 3 x 4.

Set your monitor to the correct aspect ration and the picture will look correct.

If your circles cut as ovals then your axis are not calibrated or you have backlash.

thanks Peter, yeah its just an aspect ratio thing as i suspected. I need to b more observant, I noticed in passing that u have a wide screen on your back wall, so i thought it would be fine. Sadly I did not notice the black bars on the side now that I just went back and had a good look at one of your videos.... I see the black side bars are indeed present

Is there any way I can get masso to display on a wide screen without losing 20% on each side to black bars. I remember Mach having a plugin or similar for wide screens. It would be nice to be able to utilize the wide screen to its full potential
