5 axis CNC trunnion style was created by kevincrosser@hotmail.com
Hi,
I will introduce myself. I am a hobbyist that started milling some small parts on a pocket nc 5 axis machine. I can find my way around most of the software and hardware I need to use. I never build a CNC machine nor have the knowledge of all the CNC terms. I'm currently orientating on building a diy milling machine. I currently own a pocket nc machine. This was good to learn the basics but now I want to build a much more capable machine. I want to build a 3 axis VMC like machine and when that is done build the 4th and 5th axis on that machine. I think it will be a trunnion style 4th and 5th axis. I did some research and the steel work I can do myself and I can flatten the parts for the linear rails on a other much bigger milling machine. I'm thinking about using the mesa cards for control in combination with linuxcnc. This is also what the pocket nc machine uses. The 3 axis part is not that complex software wise. The part where I can't wrap my head around is the 5 axis configuration. Is it possible to build a post processor for fusion 360 for a diy 5 axis machine or is this way to difficult? For the pocket nc the 5 axis design is in a fusion 360 design and I need to draw the part in this design to be able to machine it. How will this work with linuxcnc? I also see some information about ToolCenterPointControl. Does this change a lot in the way of drawing an building the post processor?
Hope that someone can help me out to get some things clear.

Sorry for the late reply, was hoping someone else with more knowledge will answer, but i guess it was missed.
If the PocketNC works with Fusion360 and LinuxCNC, then that is the answer, it does work.
You can download LinuxCNC from here:
linuxcnc.org/downloads/
The Stretch version, burn it to a USB drive, boot the PC from it and choose Live. That will boot the whole system with LinuxCNC in it so you can play with sim version of LinuxCNC with no hardware attached and check the different simulations of the 5 axis machines included. Even if there is no machine like you plan to build, there is always the option of changing the kinematics and making it work . There are also the visual representations of the machines there, so you can see what the machine is doing at all times on the screen.
I am not qualified to answer about TCP and Fusion360 as i do not use them, well used TCP on a KUKA robot several years back, but still to short to be helpful.
Post processors can be modified to suit your needs, in most cases, so that should not be an issue.
