Hi All,
I wrote a python extension for axis that allows C language style extensions
to the GCode if anyone wants to give it a try.
http://tsemsb.blogspot.com/2010/04/cgcc-gcode-with-c-constructs.html
It allows you to write code like this:
// Constants
const float X_Holes = 10;
const float Y_Hol
I went through this exercise not too long ago.
Short answer is that there is no way to do it in gcode that I could find.
However I did find some tricks to get around the problem, none of them
really satisfactory though. This is to control an axis independently
without adding more computers.

Hi everyone,
Is it possible to send the Y axis off on a very long rapid while doing
coordinated motion with 2 other axises while the Y is travelling?
The reason I would like to do this is that I have EMC2 controlling a pick
place machine using generated GCode. The machine picks up a chip, bangs

Hi all,
Hoping some people that have tuned their servos with EMC2 might be able to
share some of their insights that they learned during their tuning with me.
I built a pick and place machine with a servo on the X axis and I started
running tests to tune the PID loop for the servo. Right now, I

Hi,
I was using one of the inputs to read my E-STOP button which shorts to
ground when triggered, but I kept on getting false positives. I looked
at the input pin in halscope and saw a square wave that goes high for
2ms then low for 2ms and repeats. I removed the E-Stop button and

I've noticed that if I load a gcode program like this in AXIS

Is there a setting to suppress the first print when it loads?

I'm deciding on what servo drive to use with the mesa FPGA card and it
doesn't look too bad since there are not too many low cost options. I'm
constrained to a NEMA 23 size motor since a NEMA 23 stepper is on the
machine right now and I want it to be a direct swap. So far I've found

I'm leaning towards getting a mesa 5i20 or 5i23, but had a few questions
that someone might be able to answer.
Does anyone have a picture of what the mesa 5i20 or 5i23 looks like when
it is installed? Did it come with cables for the IO? Is there a
breakout board for it?
Thanks!

I know I need servos. The only low cost servos I have found so far are
