Hello all. New to the forum and hoping for some help.

Machine is a recently acquired XYZ750 LR VMC with a Siemens 828D control. My first CNC machine and I am still learning programming. I can programme on the control using Shopmill conversational language reasonably well for a newbie.

I have also recently started using Fusion 360 as my CAD programme and because of its CAM functionality. I’m only a few weeks in but am OK with CAD and also OK with basic CAM tool paths, tool library’s etc.

So I thought I’d try and run my first G-code on the mill today.

I post processed using the Sinumerik 840D post downloaded from Fusion 360 post library. It is un-modifed.

The G-code loads to the machine OK and I can view and scroll the code on the control.

The issue came when I tried to run the Simulation on the control. At this point I got an error message “11790 // channel 1: Block N24 illegal T number 1”

I think the issue stems from the tool numbering and naming in the F360 library not being liked or processed correctly so that the Siemens control can recognise and run it.

I’ve tried tweaking G-code and adjusting names and details in the F360 library but to be honest I am guessing at what to do.

I’ve read Siemens documentation and looked at all F360 tool library videos I can find but I cannot find a solution.

I have attached the following screen shots which I hope may be of use in looking for errors. The photos are as follows:

• “error message in simulation.jpg” – this is the error that flags up when running simulation on the control using the G-code created in F360
• “g-code first lines.jpg” – this is some of the G-code that contains the bug
• “g-code on machine 2.jpg” – this is lower lines of g-code above
• "tool library on machine.jpg" - this is my actual tool library of physical tools loaded to the machine. These are all running fine in shopmill programmes.
• “tool library in F360.jpg” – this is my tool library used to create the g-code. I’ve matched the names and turret positions in the physical world. Tool No 1 is the 80mm face mill which is the first one called up and where the G-code fails.
• “80mm face mill page 1.jpg” – this is the tool page for the above mentioned face mill with basic naming information that feeds through to the G-code
• “80mm face mill post page.jpg” – this is the last page of the tool in F360 that tells G-code what the number, turret position, etc is.

I tried to upload the actual g-code but this site did not like the .ppf file format,

Lots of information here but I hope to an experienced / trained eye it will help spot the issue and someone can recommend some things I can try.

G-code is just text, so you can just paste it into the regular message body, or if you want to make it separate, you could put it in a Quote box like this:

Line 1
Line 2
Line 3
etc

. . . or use a screenshot or photo with a .jpg or .png file type.

Here is the first part of the g-code.
