[Emc-users] Two steppers - same axis
Well, I'm finally to the point where I can hook the 'pooter to control box and the control box to the machine. I've got a moving gantry two-axis machine, using the X and Z axes, with dual rack and pinion set ups on the X axis. I thought I'd archived a whole bunch of emails and other discussions some place about configuring and running two steppers on the same axis, and how to home and limit switch them, but I can't find that archive on either my home or work computer. I also did some searches on the documents to see if there were any instructions there for setting up systems like this but was unable to find anything (may have been the search terms i was using). Anybody have any locations in the doccy's, or possible links to setting up a system like this?

Re: [Emc-users] Latency test numbers confusing
If the GUI latency test gives a result of how EMC will perform I always wondered if abusing the computer during the test does not result in an overly conservative number. I never use the computer that is running EMC with any other program until the parts are done. (Am I the only one?) There can be a dramatic difference between the latency test running by itself or the test running with everything else we may be doing with the computer at the same time. On a side note I have just started testing a Dell Optiplex GX520. When you first start the computer during the first 4 minutes there are two 250,000 spikes in the test with or without SMI. So far they do not repeat again even after the computer is on for several hours. Have had similar results in the 120,000 range with a Optiplex GX260 that I am using on a mill without any problems. May not be an issue, just have to warm the computer up before cutting!

OK, so I started up the computer, then waited 1/2 hour. Then I ran the latency test for 1/2 hour with no abuse, and the latency was below 7 microseconds. I have plenty of other computers, so I certainly don't need to be doing anything else on my EMC box when it's running EMC.

Re: [Emc-users] homing using index
In your hal, use
net xindex axis.0.index-enable = ppmc.0.encoder.00.index-enable
and so on for the other axes. ('net' is a very handy syntax for 'newsig'
+ several 'linkXX' commands. = is optional and is a hint for the
reader that the communication between the two pins is bidirectional.)
In your ini, set
[AXIS_0]
HOME_USE_INDEX=1
and so on for the other axes.
I note that the documentation
http://linuxcnc.org/docs/html/drivers_pico_ppmc.html doesn't list
index-enable for ppmc and says that there's something substandard about
the index implementation, but I think this is out of date. The source
code seems to indicate that the standard index-enable pin is there.
I don't actually own any pico-systems hardware, so take this all with
just a bit of salt.
