Hi I have a milling machine here which i want to control with emc. Fo the first tests im using the "normal" parallel port adapter. I'm, however, afraid of loosing steps on my stepping motors so im planing to use some quadratur encoder to also measure the position of the axes. My questions now are:
1. Is it better to use a dedicated board which is able to control the stepper motor and readout the quadratur encoders. The board is connected via usb (usbserial modul) and the board can send a command for either speed or steps of the motor. 2. How would i readout quadratur encoder on the parallel port 3. How many stepper motor can i control maximum with one parallelport and emc? I know that question one implies writing a adaper for the hal. I have basic experience in xenomai programming. Would it be hard to implement the usb board into emc? thx allot in advance for your answer ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
