3D printing with Linux CNC

Hi guys, i am Michael from germany.
i would like to tell you first something about me, before i step into my question, which is bothering me.

I am 30 years and elektrical engineer working by a global connector company called Molex.
In my free time i am working on my CNC machine and since 5 years on my 3D printers. My first CNC machine i let run on Linux CNC previously called EMC2. It was great working until the moment i wanted more then the LPT could handle. there i had not the money for Mesa cards.

Today my CNC runs on Edding CNC because i got the components cheap and easy. But still i have a idea in mind where i want to work with Linux CNC.

I build a big 3d printer which runs currently also under Edding cnc on some used components, with nice speeds (up to 1m/sec movment) but it cant handle it mechanically with the acceleration. My plan is now, to fit a second extruder to the first one for support material and i also want to change the belts to ball screws for geting more precise high speed prints.

Edding cant handle 2 extruders, and the standard boards for 3D printers are not capable to handle external stepper amplifiers well. So my thought would be, to control it with Linux CNC like a CNC machine with 3 heatings.

Can Linux CNC do this? I guess so, according to what i know from it.

Edit: I was thinking about a 7i76E board witha 7i87 Analog extension card for the temperature feedback over sensores.

Nice greetings Michael
