Hi all;
I had occasion to do some serious hi volume resawing today, and found at
the end of the job, that those $4/roll of 10 roller skate bearing use as

As I hand code and can therefore control direction the rotaries move I can
cut against the play/backlash inherent in the cheap rotaries I use, often the
B axis will be locked though for greater rigidity.
Im mostly cutting light weight brass blanks though.
A reason I hand code is I cannot afford CA
Just as an update, I got five minutes today to try running the mill with the
same configuration as I did in stepconf, but using EMC proper and jogging

if you have a XYZAB machine like my cinci (AB tilts the tool) a kinematics
in the machine allow me to program a drill cycle, use W instead of Z, and
drill along the axis of the tool no matter what angle the tool is tilting.

A cam system will still need a 5 axis post processor to be able to output 5
axis gcode.
It will need to be matched to the machines kinematic capability.
The simplification of programming a (in the control) kinematic module allows
is plain operator/programmer readable code.

Hi Dave:
So when are "special kinematics" needed? When are they not? Are you
rotating your gear blank about A&B to establish the desired cutting plane,
locking it in that position, and then cutting with XYZ?

that is exactly correct for conventional 4/5 axis control
if you want to simplify the programming you can develop kinematics for the
machine
this will allow simple programs to do complicated motion - it is not
necessary for 5 axis motion - sometimes it is not desirable
to get where you need to go

Thanks for the offer of help with files and what not. I may take you up on

Hi,
a very good simulation software for generated g-code and how it would be
executed are "the metacut utilities". It can simulate the stock and the
used tools to show how it will be processed.

Ah, OK. I do need a visualisation of the cutting process, but a
visualisation of the machine would be nice on our simple 3-axis mill.

The jumps I see only happen when a running GCODE program is stopped. It does
not happen when you switch between modes manually or switch between MDI or
manual.
I am pretty sure the kinematics forward and inverse are OK - the C on A
transformation seems quite simple.
I see it in the vismac
did you look at vismach under sim
The 'vismach' directory contains a number of configurations that
display a 3D model of the simulated machine.

Ah. Really? I can import my one G-Code and simulate it? Thanks for the
tip, I'll see what VisualMill can do. If I remember correctly it's not
that expensive.
Does anyone know a suitable framework/library

Yupp, cut off the old 26-pin connector, installed new one, tested with
multimeter - all the pins were OK, installed the cable and EMC does
not complain any more!
Now I have a question - how do I create 6 stepgens on 7i43
there are gcode examples used for demos in the EMC2 install
compare them to the code generated by your post processor
you should need to (maybe) change a few of the G and M codes to allow the
EMC2 control to function properly
all the axis position numbers should work as they are

I agree with Kim. In our EMC2 controlled machines we use programs posted for
Haas, Fadal, Fanuc and Yasnac controls.
It takes very little, if any, adjustment to use them in the EMC2 controls.

EMC2 gcode isn't too different from Fanuc, maybe you could
select Fanuc output as a test and see how it treats you?
I'll bet it wouldn't take much more fiddling beyond that.
Or maybe you can copy the existing Fanuc settings to new
EMC2 settings and then fiddle with them freely?

been sorted out and the 5-axis simultaneous control through EMC2 works. The
