Here I will be listing out my VCarve GRBL post modifications. To get started, open VCarve, click File, then Open Application Data Folder. This will open a new window. There are two folders you want to make note of. PostP has all the built in processors. My_PostP is where you'll put your modified post file. **Note: If any post processors are placed in the My_PostP folder, they will become the *only* ones displayed in the Post-Processor list. Open the PostP folder and copy Grbl_mm.pp to your My_PostP folder. After copying the file, rename the copied file to OB_grbl_mm.pp. Open OB_Grbl_mm.pp with your favorite text editor. The first change to make is to the "POST_NAME" variable. Change Code: POST_NAME = "Grbl (mm) (*.gcode)" To Code: POST_NAME = "OpenBuilds Grbl (mm) (*.gcode)" This will change the display name that you will see when you select your post processor in the VCarve UI. Second change; remove tool call Find the following line Code: "T1" And put a + sign in front of it. It should look like this when done Code: +"T1" Save the file. Restart VCarve for it to take effect. That's it for now. I'll update this once I have a chance to really dig into this.
