Hi Steve
I just last week finished fitting a trunnion and rotary table to my milling
machine. The kinematics programming and machine simulation with VISMACH has
been sorted out and the 5-axis simultaneous control through EMC2 works. The
machine is a XYZAC configuration.
There are some mysterious

There are some mysterious behaviours that I am currently looking into, such
as no MPG jogging in world mode, and sudden jumps when you stop a GCode
program.
This one seems similar to the problem Leslie Newell yesterday wrote
about. Unfortunately I

This is a limitation that is addressed (or partly addressed) in the
joints_axes3 development branch.
and sudden jumps
agreed - the kinematics is in the g code program - just having the machine
control the axes is enough to be able to cut 5 axis parts

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?

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.

Hello,
not directly EMC related, but maybe you have some advice for me:
I'm looking for a way to simulate a 5axes milling process. I'd like to
create an animation so show how the material is removed form the stock.
I don't necessarily need a ready to use program, a framework the allows
this
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

Hallo
Mechsoft Visual Mill will do what you want but it is not free, but works
well.
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

did you look at vismach under sim
The 'vismach' directory contains a number of configurations that
display a 3D model of the simulated machine.
not really sure what you might be looking for

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
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.
Ciao,

Hello,
I added a fourth axis to my three axis gantry style router. This is to
control a plastic extruder. After this addition I got strange errors. For
instance jogging does not work sometimes on one axis or after homing
correctly the position in AXIS counts up slowly but nothing is physically

I was under the impression that the kinematics had to be written in EMC2 for
the coordinated movement between all the axes to function
Hi Rudy:
Thanks for the offer of help with files and what not. I may take you up on
that in the near future. Right now I have to wrap my head around this
kinematics thing as it appears I don't fully understand how the whole EMC2
system works. Or am I getting confused with the different
Kirk:
Yes, your excellent work is just what I had in mind when he got his machine.
I remember coming across your work when I was working on getting my Bridgeport
Series I CNC retrofitted. Thanks for the help on that one too. So do I
understand you right in thinking that you can upload files
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
Hi Dave:
So when are special kinematics needed? When are they not? Are you
rotating your gear blank about AB to establish the desired cutting plane,
locking it in that position, and then cutting with XYZ?

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.
If you have a program
one example
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.

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
the axes. I only have X and Y connected but the both jogged successfully, so
when I get back from work travel I'm going to start looking at hooking
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
