Floating Head TNG.

[MrEmo]

Hello.

I am converting from USB to TNG.

But I am struggling with the new layout for inputs sensors etc. How do I setup a floating head with the TNG?

Found some help in another thread.

But I have now downloaded the sheetcam post processor and when I try to generate code I get a lot of errors in TNG.

See attachment. Any ideas?

I figured the sheetcam post processor would be plug and play?



Also, is it really neccesary to "probe" twice? This is a plasma table and I've had no issues with probing only once on the old cncusb controller. I would figure probing twice would take more time? Time = Money.

Simply set the slow probe speed to 0 and you only get one Probe move with the high speed.

I'm using the post processor for sheetcam that PlanetCNC have made.

I'm trying to edit the text in the pp.
Here is a cut out where I supposed the settings are written:
post.Text ("o<measure> sub\n")
post.Text (" M73\n")
post.Text (" #<z> = #<_z>\n")
post.Text (" F#<_workoff_speed>n")
post.Text (" G38.9 Z#<_sensor_thick>\n")
post.Text (" G38.2 Z-1000\n")
post.Text (" G92 Z#<_sensor_thick>\n")
post.Text (" G00 Z#<z>\n")
post.Text ("o<measure> endsub\n")

And this is not like the Script in TNG:

See attachment for the post processor I found for sheetcam.

This is obviously not up to date at all.

Any help to make it up to date?

Is there anyone running plasma cnc with the TNG?

[PlanetCNC]

You have old posts. You should get latest posts. They are included in "Samples" folder.

[MrEmo]

Where can I find those? In the install folder?

[MrEmo]

You have old posts. You should get latest posts. They are included in "Samples" folder.

You should make some more blogs on your site. I am scoundering random posts and finding info that helps with different problems than what they address.

[MrEmo]

Found the samples.

But they are giving me new errors. See attached photo.

This is the code in the post processor. Why is this different from the guide you have on your site? https://planet-cnc.com/measure-work-...ovable-sensor/

Also, the program skips these events entirely.

I had to remove all the "calls" since it wasn't able to process these lines.

Code in post is different because it does different things.

I just tried SheetCam to make sure everything works as it should and it does.
Here is generated g-code.

Yes it generates the code. But it is skipped entirely when you are running the code in TNG. It doesn't do anything with that code at all. It does not touch of.

And if it were to get the settings from TNG it would be different settings then the ones we are setting up in the blog you have. So you have to correct one of them.

You can't have a blog that tells you how to do something and then it is wrong when you get to the post processor. Which in my case isn't working at all.

It is not getting the speeds which you have setup in settings and it is just bypassing these lines when you run it.

[PlanetCNC]

Blog is not wrong. It correctly describes how to use moveable tool sensor to measure work position.
Floating head is different thing. It uses tool offset settings to measure offset between plasma tool and sheet metal.
G-Code that I posted is correct. It measures and adjusts tool offset before every pierce.

Will you then upload the post processor you are using?

The one in the samples is not working correctly.

[PlanetCNC]

Please post generated g-code.

I'm using post version 16/12/2019. It same one in "Samples" folder.

[MrEmo]

This is what I am getting when I'm using your sample right out of the box.

[PlanetCNC]

Please post generated g-code and your exported profile .zip file.
You can send it to our support email.

[MrEmo]

Sent it to you now.

[MrEmo]

Still not working like it should.
Here is the code.

Machine and work set to 0. The measure thing does absolutely nothing. If I set 0 10mm above material it still thinks 0(10mm) is 0. So it goes down measures, goes up to 25 and down to 13.8 and starts cutting.

Also the program does not turn off the torch after the part is finished. It first goes up to Z15 and then turn the torch off.

This post processor has so many bugs in it.

[PlanetCNC]

This g-code is correct and behaves exactly like it should. Post is correct.
If behavior is like you described then you don't have machine correctly configured and/or you don't know how to use it.
