I believe I had this same problem and I switched to Diameter mode and it fixed it.

Give that a try but I'm sure Rich will be here soon to tell you -

Got to go, back later today rich

sanlee,

RICH

Ok, so I was part right........lol!

Hi, All

It's a Chess King, This is correct mode, Hear anyway, Radius mode and Reversed arc's unchecked.

I appears after Mach3R3.041 there are Display Issues in Mach3

Chip

Chip,
Just upgraded to MACH 3.042.020 and also see the issues with the display, so your not alone.
In fact for some reason it won't zoom out as far as it did before which is very annoying. Can't even see
a small part any ideas?
RICH

RICH,
sorry to say you that i have tried the file in diameter mode and reversed arc's unchecked but still there is no improvement in result. Also i have updated Mach3 R3.04 and opened the same file but still result is same as shown in below photo. i dont know what is wrong with my side.
