First time post.
I have been experimenting with EMC2 using servos. I have been trying to get a 3axis system buildt but one step at a time. So far I have managed to get one Axis with a full servo using the ETCH.hal example. This has worked well however the feedback from the computer is not as fast as I would like and the motors end up taking off. I looked into some options and found the Pluto Servo board http://www.knjn.com/ShopBoards_Parallel.html
I ordered it and installed the firmware "pluto_servo.rbf" which is in the new version of EMC2 ver 2.1.1. I have got AXIS to load, however when I connect the encoder signals I get no feedback. And nothing counts on the screen. Im not really sure if its the wiring I am using the diagram found here http://emergent.unpythonic.net/files...uto_servo.html . I connected the first inputs QA0,QB0 GND for the encoders and UP0,DN0 for the motor.
One thing which might be the problem is the HAL file I'm working with. It is the included one in EMC2 for the pluto servo. Im not that great at the writing of the HAL files i managed to modify the ETCH to get it to work but the Pluto on is another story. I know that the Pluto Servo Example is for a lathe but the inputs and motor signals should be the same for the most part for testing.
If anyone has any experience in writing a HAL file or has written a 3axis one for the pluto any insight would be greatly appreciated. I'm not really sure how to setup this system but I wanted to keep making progress.
