Mesa for industrial milling machine was created by A_ekis
Hello everyone, although I have been reading in the shadows for a long time, I have just registered and this is my first post.
I own a mikron cnc milling machine but with dead original electronics.
I have a small machine using mach3 and a cnc lathe but with its own program, in this case I wanted to use linux cnc.
electronics is not my strong point, so I decided to go the easy way to remove everything and put new and modern servo motors.that part is not a problem and it is already solved.
The doubt comes with the card that I need to control everything, from how much I have read in the forum, it seems that the mesa ecosystem is a good solution, but I cannot fully clarify which cards I need for what I want and that is why I have decided open this post.
the requirements would be the control of servos in the three axes, (perhaps a quarter in the future).the main motor through a speed variator (I do not need to control the gearbox of the machine, the variator seems simpler, the use will not be industrial, I do not need to take advantage of all the power of the motor)And also if it is possible to take advantage of the digital scales of the machine to create a double closed loop in the future.
With these requirements, which cards do you recommend buying? and first of all thank you for your help and excuse my English as a translator

If your servo drives take analog control signals, then a 7i97 is a good place to start. Up to 6 axis of closed loop servo control, plus bit of I/O.
I used a 5i25, 7i77 and 7i84 on my Maho, as the 7i97 didn't exist back then. Here is a summary of how I did it.

Thanks for your help.
His Maho must have come from the same foundry as my mikron, because they are practically the same architecture.
I will look for the information of my servos, although for now I am with a bit small provisionals because I already had them, if everything works well, I will buy some dimensioned according to the machine.
What servo power have you installed to yours? I do not know if he explains it in the video, my English is not too good, and I have only been able to take a look at the video on my mobile due to lack of time.
I have seen that the system for joining the ball screws to the servos is not the same in yours as in mine, yours goes through belts, mine has pinions with a small play between them that will create a backlash, I suppose that the machine would originally correct this with scales and electronics.
I like the system better than yours will have to investigate.
Cheers and thank you again.

I have the original indramat drives and motors. I think they are nearly 2 hp.
