I believe they are 100 series. Site is bookmarked for when I am ready to 
make real swarf.  That will be half a year down the log at my present 
rate of progress, too much stuff to carve from scratch and too many 
other things to manage around the house.

OTOH, progress is being made, I found a pair of 1 horse 3 phase motors 
for a 60 dollar bill that my fake inverter runs fairly well, so it will 
be a lot rarer that I need to use the noisy backgears. They appear to be 
happy at 20 hz, or 180hz.  I ordered up 2 sets of bearings and replaced 
them in the noisier of the two, sweet & quiet now.

Thanks Cecil, take care now.

Cheers, Gene Heskett

[Emc-users] Sunday afternoon news from WV. Wierd,

[Cecil Thomas]

Gene,
You don't have to use Phase II.  All AXA or 100 series holders are 
interchangeable.  You can get the the holders here for $10 or $11 if 
you want the groove in the bottom so it will hold a boring bar securely.

I'm pretty sure the holders you got were AXA or 100 series but check 
to be sure.

Re: [Emc-users] Setting axis as homed

[John Thornton]

That's only true for Master, for 2.7 you still need to say:

[TRAJ]

AXES = 4

[John Thornton]

If your using a home sequence so home all shows up in Axis set then 
setting the home search velocity to 0 and that axis homes where it is.

Re: [Emc-users] Setting axis as homed

[alex chiosso]

Hi Eric .
You should just setup a machine with 2 axis (X-Y) or the number of real
axis you need for the application as Ralph suggested.

Re: [Emc-users] Setting axis as homed

[Eric H. Johnson]

Ralph,

Thanks. I will have to try it. I remember when I first configured it, that I
had a problem skipping Z and going on to A, so I left Z in there
unconfigured.

Regards,
Eric


You can define any combination of axes in the ini file that you like.
Define them like this:

[TRAJ]
AXES = 3
COORDINATES = X Y A

[AXIS_0]
TYPE = LINEAR
...

[AXIS_1]
TYPE = LINEAR
...

[AXIS_2]
TYPE = ANGULAR
...

Hi Eric.
Why are you using an axis (Z) to drive a pneumatic cylinder ?
You should drive it as a discrete output using a custom M1xx function and
setup a 2 axis machine instead of a 3 axis machine.
Can you explain better your application please ?

[Emc-users] Setting axis as homed

[Eric H. Johnson]

All,

 

I am trying to use "force home" on a machine which has X, Y and A axes. The
Z is a two position air cylinder, so not controllable as an axis, but does
appear in the configuration with basically nothing attached to it. Is there
a way to set the Z axis as "homed" (axis.N.homed) so that when NO_FORCE_HOME
is false, it does not give an error that the axis is not homed when trying
to run?

 

Thanks,

Eric
