I have designed such a cnc ... and in addition it has a 360 degree rotating axis.
there is a double-sided drill at the end of this axis.Drill of different diameter on 2 sides.(8 mm on one side and 10 mm on the other side) I will use it to drill the edges of the mdf.I should also note that up and down movement of this axis will be provided pneumatically

how do I configure this machine in linux cnc?
some people said post process needs to be written.Do you really need it?
I would appreciate it if you tell me where to start and what to do about it

Thank you in advance for your interest and help

Merhaba abey,
First you have to make the machine work as you need it to, then deal with post processing .
Did you build the machine or not yet ?

You are in Turkey, are you aware that you can buy ready made frames with linear rails, ready to be fitted with motors and electronics ?

yes I know but the cost is too much. I do not have much money. Did you find a problem with my design?

No, it looks OK.
I would set the gantry a bit lower as it would be more rigid, but maybe you need all that space below.

I originally designed it with a 5 axis head. so the bridge was high I could drop it a little more. The cnc dimension is 2750 mm x 1500 mm x 750 mm. What is the ideal ideal bridge height? What badly affects the high bridge?

Well if you go that high, you have to set the carriages much wider, and strengthen the sides that carry the gantry.
