hey guys, first post here, I've been lurking and learning for a long while now. I'm def an admitted noob with cnc but I'm a big believer in searching for answers and reading, studying and learning instead of just asking questions, but this problem had got me stumped and I've been searching for hours but not finding anything like my problem so I figured I'd just ask
I'm working with a romaxx router and what I'm having a problem with is a simple little gcode that I wrote to profile 2 corners of a small wood panel. now where this problem gets strange is, I wrote the code and cut a few parts and it was working absolutely fine. the radius of my curve was good and it matched well to the part I need this to fit into, everything was good. then, all of a sudden, with nothing else changed (as far as I know), mach3 started to, instead of making a rounded corner, it just started to cut the corner at almost a 45 deg. angle. I'm running this real slow, at like 20ipm and again, it was working fine just a few minutes before.
I reloaded mach3 and even restarted the pc but nothing helps. what's even more strange is, it even shows this weird 45 deg. cut off corner in the tool path preview instead of showing the arc that the gcode should be??? this has me completely baffled because just minutes ago it was cutting this same arc just fine
here is the gcode for this part:
%
(main door)
g00 g20 g17 g90 g40 g49 g80 g61
x3y-0.95
m03 s15000
m08
g01 f20
z-2.45
x-0.65
g02 x -1.05 y -0.55 I0 J 0.4
g01 y 0.485
g02 x -0.65 y 0.885 I 0.4 J 0
g01 x3
z0
m30
%
here is what the curves should look like
but here is how it displays in mach3's tool path preview (don't know why it rotated sideways)
and here is the difference in the cut, I cut several like the one on the right and it was cutting perfect, and then all of a sudden it started cutting at an angle like shown on the left with the same exact block of gcode...
any help would be appreciated, thanks
