hi,
thanks for the response.
The mesa card is used for pwm generation ? What do i need then for the servo/stepper power, which i control with the pwm signal, or?
Do i need a second card for controlling the power (H-bridge, or anything?)
thanks for help

> What is a good (good supported) controller-interface (pci-card, usb,etc) ?
LinuxCNC doesn't support any USB interfaces for machine control (there is support for human-machine USB interfaces)
For stepper motors the Parallel port is cheap and often entirely adequate. Of the devices listed on the Wiki "supported hardware" page the devices with the best support are from Pico and Mesa. The Mesa 5i25 + 7i76 is a very good combination for PCI-based control of stepper machines.
Note that the Pico solutions use the parallel port for communications, not to pass step-dir signals, ie both Pico and Mesa products move step signal generation and counters into hardware.
