I'm not sure what is happening behind the scenes but under Pathpilot you can
configure G30 to only move in Z. I've used that feature for years without
realizing that it was non-standard. From the Tormach manual:
Go to G30 Button - Causes the mill to move to a pre-defined G30 position,

Hi Stuart,
You can see that requirement in the arArcTest3_4.png I tacked on in a previous
posting.
The center point of the new arc has to move to a new position such that the
starting radius from center to XStart and YStart matches the radius to XEnd and
YEnd. The position of this center is r

I'm a bit confused here then.

This goes at max speed to Z 0.5 which makes sense.

My G30 is setup to move in Z only.

It does run on my LinuxCNC like a charm once I remove the request for the
unknown tool. Very sm
It would certainly be shorter if they did a little looping!
I'm unclear why they vary the feed with each segment.

Fascinating. Doesn't really do a spiral at all after the initial helical entry
to cut the starting hole. Then just a series of short straight moves until it's
roughed out the hole and then does one circular finish pass.
Nice to see how well the Tormach documents each of the moves. I really lik
It was a little while ago I wrote that, I'll try to decipher. The pocket it
was making was a fixed size, and the parametric part changed the step over
amount. The pocket size was 2.5" and is controlled by the 1.25 (radius) in the
line N30 while statement.
The tool was a 1/4" diameter mill,
I decided to see what Tormach generates with their conversational programming
in PathPilot (LinuxCNC pretty face). I don't recall the original parameters so
I requested a circular pocket, 0.5 deep, 1.0 diameter, at 0,0, 0.5 DoC,
1/4-inch cutter (what was in the spindle). It spirals down in a 1/2
I’m guessing the literals 0.125 in the G-Code program represent the tool size?
Can't quite figure out what parameter is the diameter of the hole.

And its a cast iron bitch.
I bought the big 2 piece heat sink from banggood, which it appears will
cool an rpi4 really well once it arrives where theres a small fan
blowing on it, allowing over clocking to 1.8GHZ if need be.
BUT theres always a BUT. The heat sink won't allow a 40 pin header soc
Gentlemen,
When using the R register in the circle interpolation routine the control
calculates the center point. It is almost 100 percent certain the center
point coordinates calculated using the R value are NOT the same coordinates
you use to calculate the IJ registers you put into the routine.
I had taken the time to work out an approximation of a spiral using IJ arcs
using parametric code for a Fanuc machine once.
Here is what I had.

#100=0.07 (LOOP OVERLAP SIZE)
#103=100. (FEED RATE)

In the past when this I and J error would arrive .
I would go back to qcad and convert the drawing to metric.
Then recompile the gcode in metric which would usually work for me.
Only a suggestion.

Ok so a friend of mine has tasked me to convert his machine to Linuxcnc.
All of the control components are ethercat.
Are there any restrictions or recommendations about motherboards or NIC
cards that I should stick with?
Thanks,
