When i bring the pnc kit into NX, the MCS gets located at a csys on the top sirface of the vise. This doesnt work, i have to manually move it to a location a bit higher than the vice so its aligned with the Z axis and the b-table axis.
How can i get this to happen accurately and auromatically every time i start a new part?
Have i loaded the lit correctly or am i making a mistake somewhere else setting up the machine?
Thanks,
Ken
Hello at Ken
The machine kit will load and be placed at the center of 4th and 5th axis pivot/rotation. This is editable in the machine kit top level part file with an expression and should be changed to match the value provided in the machine’s documentation. This is the G53 zero and is set as main MCS. You should add another MCS object and set as the local MCS with a number of 1 or higher. This will be G54 or higher. 1 = G54 , 2 = G55 etc. this is usually the workpiece setup point/touch off point. You can also set a CSYS rotation etc.
it’s ok to have G54 MCS at the G53 position if that’s what you like also.
I hope this helps if not I can help more on this and maybe send a video on how it works. There should also be a word document in the machine kit folder that shows the setup.

Thanks! Really great to have your help (again).
I went through very carefully and followed the installation instructions for the V2-50. I didn’t see separate expressions in the V2_pocketnc_v1.prt file for both B_Table_Offset and baxis_offset. Regardless, my offset of 0.8314" was already set correctly, and the same for the -0.8314 in the post configurator Real Machine Kinematics.
In the V2_pocketnc_v1.prt file, the csys is where it is supposed to be—on the Z-axis at the level of the spindle axis and also on the A/B rotation axis. But when i bring the part and the machine together, the part and MCS are placed directly on top of the vice. This results in an error of ~8mm off-center of the A/B axis (in the -Z direction).
If I move the MCS up 8.4086mm to the intersection of the Z and A/B axes, it cuts on center like it is supposed to.
Previously with an earlier version of NX (1859) and a different computer/installation, I recall having to move the machine in the V2_pocketnc_v1.prt file by this ~8mm amount to make things work.
Currently I am running version 2206.
In your previous reply, you recommended adding a G54. Would this be at the ~8mm above the other definition? It’s not clear to me yet how this solves my problem, or how to correctly implement it, but I’ll keep trying and hopefully you can clear up some of my misunderstanding/ignorance about how to setup my workflow.
…After fiddling around a bit more, I’ve got a working template where the MCS has been moved and I’m able to bring in different geometry and it cuts fine. I’d still like to understand how to get the machine to load with the MCS where it is supposed to be, but at least I can cut parts now with my template 
Hi @ken
I’m not sure why its coming into the wrong location, this could have been a bug that was fixed in a later release. There isn’t much I can do for NX2206 now as it’s EOL probably, If you can test on a newer version and see it the issue persists. The G53 / G54 Main/Local CSYS is super flexible. Use a new MCS if you want to gauge off a specific point on the workpiece, if not it’s ok to leave the MCS at the rotation center position specific to your machine. Both is ok, it’s just the reference for a set of operations or csys rotations that will dictate this and is specific per part you make.
I’ll check on the install operation documents and post it here. I’m happy to have a teams call etc if you want some addition help or to show me your workflow. I’m sure we could at least improve the situation.
When adding the machine there is an initial reference dialogue that pops up and you can select Absolute or Machine Zero or something like that. I’m away from my pc at the moment but take note of that also.

Hi TP,
Thanks again for your help. I’ll keep developing my template and add a G54 into my workflow, while digging into what could be happening.
I suspect the issue has to do with the fixture/vise and how it is entering into the junction setup. There are two sets of csys’s in the non-timestamp geometry, but I’ve not been able to find out where they are defined.
I very well may take you up on a teams call after I exhaust exploring the many fabulous nooks and crannies in NX. I’m also interested in building the pendant controller you’ve described.
Regards,
Ken
Hi Ken
No problem. Reach out when you’re done with your tweaking and we can setup a call.
Cheers
Hi TP,
Ive made good progress and am ready to have your help optimizing my workflow and revolving a mystery or two about the csys behavior.
What days/times are best for you?
Cheers,
Ken
Hi @ken
Anytime next week. I’m in Japan time zone so early morning probably lines up with you. Say 8am Japan time any day of the week is fine.
cheers
