Modifying a Post

[bryce_monroig]

We recently purchased a Haas Desktop mill and added the post processor for the desktop mill that Autodesk has in its library to our file so we can post programs for the machine. When it posts the program it puts a G43 in the program for the tool but doesn't put an H# with the G43. How can the post be modified to put the H value in there?

Hi @bryce_monroig.  This might not be the best place to ask how to do something like that.  I will post a couple links below to some other helpful online help / forum type resources that may be more helpful with that type of request. 

This next link is to the 'HSM community'.  HSM stands for 'High Speed Machining', but that community has many areas, and covers a relatively wide subject area.

I would recommend checking out the HSM Post Processor Forum in that group

This next link is to the online help for Inventor CAM, but I'm not sure if that will help that much.

And by the way, they will need to know as many specific details about your situation as possible.  Such as not just what 'brand' the CNC machine is, but what specific model, and what all capabilities it has.  Which exact CAM software variation / version / year you are working with (Inventor CAM, Fusion 360, another one)?  It seems to me that there is usually a place in the settings / set-up where you are asked to select a post file.  I'm not sure about in your case, but it seems like that file is usually using XML coding language within, and can be pretty confusing, if you are not very familiar with that type of coding.  They (in a post forum) may be able to help you modify an existing post file to suit your specific needs.  Usually a 'current' resulting CNC file is requested, and one that is manually modified the way you want it are requested, so they can compare those to the contents of the XML type post file.

It appears that you have the option for "allow multiple tools" in the Preferences section of your post dialog deactivated. 

It is turned off in the post processor by default. You can edit the following line of code in the user preferences section of the post processor from "false" to "true" to activate "allow multiple tools" by default. 

Setting 15 must also be enabled in your Haas control to utilize this functionality.
