Have not tested it, but is just a copy of Uwe's code.

Just did an air run.... looks good. I will do a real test tomorrow! Thanks.

Simulation is only working with 3 axis, if rotary along +X is selected, fusion will not simulate

But with out commenting two lines it is ok

Have had some fun with the simulation...

That's pretty tasty, Uwe.

When it comes to creating the actual model of the machine itself, how did you come up with yours - did you find it somewhere (generic model for this Chinese family?) or did you have to model it up from scratch in Fusion? I previously created a Fusion model for my Colchester lathe and I recall it took me quite a long time. To do the same for my Shizuoka mill would be quite a task.

I see there is a helpful video on using Machinebuilder here

...and some more info about preparing the PP for machine simulation https://www.autodesk.com/support/techni ... n-360.html

I started with a very detailed BF20 model from grabcad

https://grabcad.com/library/optimum-bf20-1

But I stripped it down to the main parts and combined several parts into one body for each axis to improve performance for simulating.

I watched the same vid from autodesk to get started

That was good thinking. Your machine is sold under a variety of names and is a very popular design. I must search Grabcad and the other repositories for Shizuoka mills but I won't hold my breath!!

I don't fully understand it:

Afaik this basically means all the axis config can be deleted these days. as the kinematics is handled by fusion machine config and not in the post anymore. I need to do a bit more reading to figure out what can be deleted from the post and what cannot.

"It is no longer required to add the machine kinematics to the post processor script."

I will ask autodesk. I think lines 461 -> 502 can be deleted.

It sounds like this will work, then I can also remove the 4th axis selection in the PP.

I assume this way will only work with the machine definition in the machine builder.

Anyway, I need a XYZ A C PP with supporting TCP.

unless I'm missing something, I don't think Centroid has TCP (tool centerpoint point) support.

Oh it actually does G43.4
