Ok -
1) Ill get the dxf used off of the computer today, just in case it's
different with the one I have here with me. I'll put it up on the blog.
2) I'm going to re-order the cuts - and try redoing the part tonight.
3) I'm almost certain that it's an error on my side being a newbie to
Cambam.
i am with # 3 john from what i have seen thats the evidence i gather .
again though careful measurement will reveal which side it is on, also does
the tool enter near the bad radiii?

Hi all;
I have an issue with a long-running test. I was cutting a hand wheel out of
Aluminium, using the output of a CAM program (CamBam). I was twiddling with
the feeds and spindle speeds sliders, and wonder if the issue is my
twiddling, or if it is with my machine.
I seem to remember reading
C'mon John too many variables here unless you show us the G code, after all
that's what Linuxcnc runs on. It could be the CAD output, it could be whatever
CamBam has coughed up from that or shudder human error.
Are you running CamBam on Linux? Have they ironed out all the teething
troubles

Another (especially experienced) set of eyes more than welcome.
I think this will work for the GCode:
john what tool did you use to drill the center hole? was it interpolated
with an endmill? and i am presuming from the code x and y 0 is center of
the part?

Jeremy;
I used a centre drill to drill the hole. After the machining, I moved the
table back to (0,0) and put the end mill down it until a bit of aluminium
came out, and it seems to be centred still ok.
Thanks - John.

ok so the off center was a machine location and not a concern with the
program . i still presume x and y 0 were the center of the part correct?
you really have a lot of code here without comments . it looks like it is
the code fro the inside and outside profile is the outside symmetrical? i
seen
Hi all;
I have updated the blog page with links to the gcode file, the CamBam file,
and a youtube video.
I'll put the dxf file on line tomorrow; I started this episode on a windows
computer, and it's not here atm, and I want to ensure that the dxf used
matches what I have on my linux computers.
checking it out now john

Thanks for any words of wisdom anyone may have.
I don't think that the symptoms look like this, and you would have to
be unlucky for the system to exactly recover, but it is just possible
that the motor slipped a few steps,
missed steps may be andy but the interpolation segments are all pretty
short . and it is one sided . measurement of the part will tell a lot of
the story as to which side it is on . another thought is was the part held
securely? i ask because it is one sided

it is also generally more advisable to machine the center and then the
outside as this will reduce chatter on the thin walled surfaces
