I Need help for 4 axis cnc

Hi
solidcan has a 4th axis post for Fanuc11m that will shure fit your need
if not licenced you simply can use a Free Autodesk product for small busines
the 4th axis is only a setup

i mainly use them as a B axis as the Y is then the main axis and the machine dont move in X Gantry
its basicly a lathe type machine 3Axis YZB with X takeng the center pont wherever 4th axis is located at the large Table

Please watch video... with this machine I want to make holes on the 4 sides of the wooden panel. I don't want to simulate. just turn 90 - 180 - 270 - 360 degree enough for me

To my thinking it depends how you need to use the drill.

One way would be that the drill is completely independently controlled in the z axis -basically meaning you have two z axis. (maybe z and w?)

The second is that the drill when used is always use fully extended and you use the main z axis to set it's drill height.
You position the drill (extend / rotate) using HAL and then it's just tool offsets.

Andy is usually good at thinking these things through in smart ways.

I have no information about what you say. because this is my first cnc machine. Will a post process be required for the CAM program? I don't even know this... please someone guide me. I would be very happy if he tells me what to do step by step...

I do not want the machine to work simultaneously. just turn the axis 90-180-270-360 in the video and drill the hole

Please help

Thanks for answer but ı dont know HAL

all you need to know in first hand is that it will work with linuxcnc so you can start to build
the postprocess is your Word/Notpad or as you are on linux GEDIT to change your axis 0-90-180-270 by adding the command
your CAM and Post works flat out
the 2 Tools will have diferent coordinate system G54 G55 they arte on so the offset is non problem
the Z is for the First tool
the w for the Second
if it is only this 2 tools not a 11head machine it is far easyser then you think
