4th Axis Error post pro

[francois_moreau]

Hello,

I use a 3 axis MAchine, wit Richauto Postprocessor.

The machine has a Rotary Axis along Y, (with name " C " axis on the hardware)

because the Richauto postpro you can find on the HSM fusion library is only a 3 axis postpro, 

I find the RS-274D Autodesk multi axis 

I tried to make a simple toolpath,

and become an Error when I tried to postrocess it

Error: Tool orientation is not supported for available machine axes.

Machine angles not supported: A-121 C-90

could it be link to machine configuration?

or Wehre can I find how to test my machine? 

Must I edit the postprocessor?

I find the new training guide pdf about this process, but I do know wat to do with it

thanks

Not sure if the following is what you are looking for but here goes anyway. Have a look at the video first and if it`s what you need then have a look at the attached file and modified Fanuc multi axis Post Processor, hope it helps 🙂

thanks @engineguy 

with the Fanuc rotatif I could edit a .nc gcode

I hope my Machine, Richauto, will understand it, I make a try and let it know if it turn how it must.

[francois_moreau]

do not work. (but move, it is positive)

i made a small test without the 4 axis, with fanuc pp

it is working, look like ok. (I didnot take the time to mill it, but in the air it look it works normaly)

then I try the rotative test we speek about, 

and it only move on the Y axis, nothing on the C axis (like it put everything together on the Y (Y+C) )

here small video of the problem

https://youtu.be/uzzNQVQeZDU

on this video I try my file 1003.nc, but I try also your 2009.nc with the same problem.

otherwise with the DSP B-18 Richauto handle,

clockwise is C-

so try I to adapt the Fanuc PP, or make other try with a other one? (witch one?)

good here continue to find the solution or post I the question on the autodesk HSM PP forum?

thanks

Thank you for the video, I can see that on your controller there is X/Y/Z and A axis, not C Axis, that is possibly why your 4th axis does not turn, I have modified the Post Processor to output A Axis moves instead of C Axis, as far as I know your RichAuto control should accept the Fanuc Inverse Time code so give the new PP a try, hopefully it will work this time 🙂 🙂

@engineguy 

thanks, It's working much better

still not smooth, it make the first full round (A axis only turn) everything ok

then for the spiral it makes a lot off run stop on both Y and A axis

is it also possible that it run slowly as in the simulation ( about 1 minute in simulation (for the first toolpath and a second minute for the second), but much more needed I thing on the CNC)
