Resolution and speed with servo motor

Category: General LinuxCNC Questions

dirhold and dirsetup are the restrictions i think

I have the same issue on mine. I had to increase them to 20000 which in turn restricted my top speed to 12m/m (with my screw and steps per turn of course)

I need to refine this. 5000 drops steps, but 20k is overkill.

60000 seems very extreme. is there a reason you have it set that high?

Exercise: Turn on output led on EL2809 when machine is turned on

Category: EtherCAT

I have spent a lot of time reading the manual but unfortunately I could not put togheter all the pieces to come up with a solution, I'm pretty new to LCNC and I would like to learn by doing, had the idea to turn on an output led on EL2809 when machine is turned on. (have succesfully installed following Rodw guide)

In HalShow I can turn on and off the led my hand with SET CLR buttons, so it works manually.

I found this info : motion.motion-enabled - (bit, out) TRUE when in machine on state.

Also from the manual: 5.2.1.4 net
The command net creates a connection between a signal and one or more pins. If the signal does not
exist net creates the new signal. This replaces the need to use the command newsig. The optional
direction arrows <=, => and <=> make it easier to follow the logic when reading a net command line
and are not used by the net command. The direction arrows must be separated by a space from the
pin names.
Syntax and Examples of net
net signal-name pin-name <optional arrow> <optional second pin-name>
net home-x joint.0.home-sw-in <= parport.0.pin-11-in

So I guess I have to combine these two, but I have no Idea how to do it.
Please Help!
