RTCP Support

[Chaz]

Hi,

Noted from some of the recent comments in suntravel's Acorn Six build thread that RTCP support is 'soon'. Could we have some understanding of timelines and which hardware would get the feature etc? Will Post Processors (Fusion 360 specifically) be modified to use etc?

Thanks

Centroid is not making Post Processors.
Current Centroid mill PP from Autodesk is capable of multiaxis with machine simulation. Because the Kinematic is coming from the Machine setup in fusion and mus not be build in the PP.
If there is something missing for TCP I will try to add it.

Thanks. It was more that Ive seen unless some support for a PP that works, the functionality isnt always usable. I recognize that Centroid dont do the PP, but my point is that someone needs to (Ive got limited skills in this area).

Can anyone confirm when / where the RTCP feature will be available?

As far as I can see the current Centroid PP from Autodesk is TPC ready almost.

To test this out and make adjustments I will wait for the TCP implementation in CNC 12 for AC and BC configurations.

From my side the test machine is ready to go.

I am hoping more users are waiting for this so it will pay off for Centroid.

Ye, be nice to hear from Keith (or someone else in Centroid).

Ive got a 5 Axis Mill with A / C setup running UCCNC. I didnt go for Centroid at the time due to cost and no RTCP. UCCNC doesnt do it either but the controller / daughter board was fairly cheap in comparison. Its only worth upgrading if I get some benefit.

realistically RCTP is going to take time.

to get things off the ground we need a clear definition of the desired action of a general purpose RTCP function. who wants to take a stab at it? you guys know what you want, tell me how you think it should work, i don't want to build some software that doesn't do what you are expecting it to do.

insight to our project priorities, RTCP is not actively being worked on by Centroid at the moment we are frying other fish (such as but not limited to: better RTG graphics, improved CNC12 APi features, EtherCat 2.0, 3D pwm VM with smoothing on, Fiber Laser CNC Control system, improved axis pairing techniques, asynchronous axis beyond the 8 fully interpolated for Hickory, real time axis position adjustment via MPG or scale while running a g code program, new CNC12 mill and router tool library and too many "little" items to list. RTCP is on the to do list after these items. Now with the cool machine that Uwe built we have a great alpha tester. So lets get a good requirements definition down on paper so we can start working on it!

Thanks. That's very helpful. I dont know much about it other than I believe it makes simultaneous multi axis machining easier and I believe 'smoother'. If I explain, Ive got UCCNC running 5 axis simultaneous. It is 'jerky' however after speaking to RosettaCNC, their stuff looks good but is pricy but they reckon RTCP (which they have) is one of the 'tools' that makes smoothing a lot easier. I dont know if this is true, could just be snakeoil ....

It just feels like a nice feature and if its available, you would use it. Can I work without it, probably. The UCCNC (and I suppose many others of the cheaper type control systems, ie, a few hundred £) dont do RTCP, and that's OK. However for stuff where we are talking >£1K per a controller, it feels like it *should* include this feature.

In my case, simple gate 5 axis machine (bridgeport clone) with A and C on the table. I'd be happy to test as well. Its an existing machine, running on the UCCNC hardware which I'd be ok to remove and retrofit if its worth doing for testing purposes. I wouldnt however want to spend £1K on a controller which fundamentally may not be better (other than being Centroid which I prefer).
