Stepcraft UCCNC 4th Axis and Post Processor Issues

[Anonymous]

Hey All,

I'm machining a cylindrical object with my stepcraft 600 using the latest Stepcraft Post: Processor  https://cam.autodesk.com/hsmposts?p=stepcraft_uccnc&_ga=2.124079690.1968343632.1540450706-1220459904...

But it doesn't seem to be generating anything for my machine, the G-code file comes up with nothing written in it, not even an error code. I've had a look at old post-processors which will spit out G-Code but they seem to have weird effects like making the Z-axis do strange things (like going way out of the object but thinking they're still cutting). I can attach the F360 file if needed but just want to know if it is a setup issue or something else? 

The cut I want is basically the machine to lower Z-axis to -0.3mm, cut into the object at that height and then the A-Axis to spin, then repeat - much like a lathe, to reduce the overall diameter of the object at certain intervals if that makes sense? (pic attached)

Hi @Anonymous,

As I see the picture you like to wrap the toolpath around your model.

Have you defined the right axis in you setup witch axis you want to rotate your part around?

Also, do you have configured the Post Processor?

Thanks, yes I’ve wrapped the toolpath around the Y axis as the Stepcraft
and autodeak forums have advised that in previous posts. Also as per my
post I’ve loaded the stepcraft / UCCNC post processor.

@Anonymous from you pick it looks like the WCS is in the wrong spot can you post that model from the pick with the toolpaths To do this Go to File -> Export and save as a .F3D Archive File and attach it to your next post.

Also, it looks like the model is not angled on all faces there are a couple of hacks that can be done to get a toolpath to work the angle faces may just need a bit of BS to get them to work.

Thanks, I tried changing the WCS but it doesn't seem to be working - not sure if I am doing something wrong though so I've attached the F3d file, appreciate the help!

It is what I was guessing, what you can do is what is in the 2 videos on this youtube channel https://www.youtube.com/channel/UCrx-8M8nRa-rNlkwIowx6Kw

Also, it looks like beta mode needs to be turned on instructions here http://www.manufacturinglounge.com/hsm-beta-mode-hsmwork-inventor-hsm-fusion/

I can not get any of the multi-axis tool paths to work, if you had a 5 axis it would be easy.

Example attached.

Thanks! They are some great tool paths which I will use a lot!

I just realised what I've been doing wrong - it was in the Post Processor Properties - I hadn't selected the "Fouth axis mounted along - Y axis" - It wasn't super clearly explained in any of the previous forum posts so maybe handy for people that this is now in the forum! I've attached a pic of what I'm talking about for clarity. Thanks for your help once again!

Hi everyone,

I'm trying the 4th axis of my Stepcraft for the first time using Fusion. I already set that it's mounted along X axis in the UCCNC postprocessor properties, and I expected a G-code without any movement in Y axis. Unfortunately the g-code is moving all the axis (X, Y, Z, and A).

Moreover I have all the toolpath flipped, as you can see in the 2nd image below.

Thank you in advance

Can you post this file To do this Go to File -> Export and save as a .F3D Archive File and attach it to your next post, if you can not post the file you can PM it to me or say in your next post you can not post the file and one of the Guys that do NDA work will help.

Thank you Daniel,

you can find the file attached here!

It's just a model meant to test the 4th axis...

[daniel_lyall]

It is where you put the WCS having it on top makes that the center of rotation and for the cutter to get to where it needs to be it needs to move in 3 axes to do it.

Moving the WCS to dead center ever end fixies this problem.

Thank you very much,

now it works!

Hello 

I have issues with export from Fusion to UCCNC 4th axis. I need to mill two holes in a tube.  It looks ok when I simulate the milling path. But, when I post process it for UCCNC (Stepcraft) it changes the Z value when it mill the 2nd. hole. Therefore the tool is not touching the part but mill in the air. Can you tell me what I do wrong?  Let me know if you need further information.

Best regards Kristoffer
