I have been looking into the issue some of you have been facing where MasterCAM hangs / crashes when it is loading. I may have found a potential fix for this. In digging around I have found this to solve the problem for me:
It seems as if this issue is related to an incompatibility with certain versions of Windows, Nvidia graphics processors, and MasterCAM. This solved it on my computer, but I haven’t had a chance to test this elsewhere yet.
The section on the Bank CNC training website listed below has a thorough tutorial you should follow along to for creating surface toolpaths in MasterCAM.
I just wanted to make everyone aware that if you double click on a MasterCAM file (on your desktop or in a folder), it will open MasterCAM, but it will not open the file you double clicked on. You need to open the file from within MasterCAM.
Some of you have asked: Is there a way to update the geometry in MasterCAM when I make changes in Rhino, like you can do with the Keyshot plugin?
There is not a plugin that links the two applications like Keyshot has with Rhino, but there is a fairly simple way to accomplish something similar:
You can use the same technique to add additional geometry or to otherwise change the geometry that is associated with a specific toolpath operation.
Some of you may be experiencing a problem where your layers are not preserved upon merging from Rhino into MasterCAM. Here is the workaround to solve this problem:
Sorry we did not post this sooner, but you can get the tool library with the 15/32 bit below. You will see that this tool is tool #8 in this library. You should go back into your operations and choose this tool. You should also make sure that your tool settings are not set to “assign tool numbers sequentially”. If you do have it set to assign tool numbers sequentially, the first tool you select will be called #1, regardless of which tool it is in the library. This will cause your part to cut with the wrong tool. See the image below for a reminder where you access this option.
If for some reason you don’t see this tool as an options from the library, be sure to uncheck the option for “Filter Active”
If you have the correct tool – “15/32 Flat Endmill”, but the tool number is wrong (maybe assign tool numbers sequentially was checked), you can just go in an change the tool number:
Here is a link to the mastercam and rhino reference files for the step stool we looked over in class Monday. There’s also the rhino 3d file of the stool. You can use the layer conventions shown in the rhino file to help simplify your operation selection in MasterCAM https://drive.google.com/drive/folders/1LHZFsByQpyNWEn0OLK5sicsPlSjzzFAx?usp=sharing
It’s been brought to our attention that the method for defining the stock shown in the tutorial does not work. This is a factor of some changes that were made in MasterCAM 2017 from the previous versions. Instead of clicking on the “Bounding Box” button, click on the “All Entities” button and this will work the way that “bounding box” used to work.
Sorry for this confusion.
