Re: No Clue where to start. Haas TM-2p
We have a TM-2p, and use Fusion 360. Works well for us. The free version of Fusion 360 is a bit broken, but would still work for you. You can always upgrade later if needed.
The post processor is just the internal translator that takes the raw data from the CAM toolpaths, and outputs the machine specific G code. Fusion 360 has many included post processors to choose from, including several for Haas machines. The post processor will not be an additional expense.
