Hello,

See? That's why I love LinuxCNC: you actually *could* replace a pair of
microswitches with a webcam and a dollop of image processing software!
And it would make sense, because the webcam would eliminate mechanical
constraints. It might also give better performance at a lower cost, at

That's easy to believe. Is it perhaps feasible to retain feed control at

I've added my script to the Wiki,
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinesToArcs
It will take a gcode file (only tested with Slic3r output) and convert the
many short line segments back to arcs. It can make a huge difference to
print speed and file size if there are lots of arcs.

great job, Frank!
this might be worth considering a canon optimisation stage in the interpreter

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

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.

I don't think that the symptoms look like this, and you would have to

that the motor slipped a few steps,

short . and it is one sided . measurement of the part will tell a lot of

it is also generally more advisable to machine the center and then the
