High Speed Servo Based CNC controller board

[davidchow]

Hi,

I am new to cnczone . I am doing research to build a precise CNC miller with high speed servos . I am living in Hong Kong, so I have good access to lots of resources in China .

I recently sourced some cheap high speed 200W-400W servos with drivers . These drivers interface using traditional stepper motor signals inputs with encoder as close loop control with 1000/rev (good enough for many cases). With an operational speed of 3000rpm . The driver accepts a signal pulse frequency of 40KHz for optimum operation.

I searched a couple of days from the net, I cannot find any suitable controller board to match such speed. pluto-p and many hoppiest board are all PC parallel port based. If I am going to build a 4-axis or 5-axis (even 3 axis) machine . The speed of the parallel port is not good enough .

Does anyone know any usable PCI or PCI-express based boards that support 5 channel of stepper motor with additional generic I/O pins available?

I target to run the system using Linux .

Please give me some suggestions. Thanks.

David

mesa 5i20 should work for you, drivers for EMC2.

galil can't work with linux, right?

According to the Galil site it does.
Linux interface is offered.
