dspMC/IP Motion Controller / Re: dspmc with mach3 - output problem

I am glad you got it working.  I am not vary familiar with macros.  may be the mach experts who reply to questions in this forum can guide you soon.

In the dspmc.xml you can select to Ignore limit switches during homing:

<HomingIgnoreLimits>1</HomingIgnoreLimits>

that should fix your problem

Once you have figured out counts per mm, you can then move the axis manually and observe the backlash counts in the mach3 dspmc window.  then enter this backlash count value in dspmc.xml file for the selected axis.

hi Xavi,

the xml file section <RPM> <CountsPerRev_...> is not used by mach3.  the counts per unit (mm or inch) is entered in mach3 motor tuning window, as well as <Axis0><CountsPerUnit> fields in dspmc.xml file.

do you know the number of motor turns per mm?

eg 0.5 revs / mm x 1000 counts / rev x 4 = 2000 counts / mm


thank you
Rufi

see the graphs in this post http://www.machsupport.com/forum/index.php/topic,14603.msg98200.html#msg98200.  very nice servo step responce.

the tunning graph looks good.

for dac motor outputs, you dont need any setting in mach3.  it is loaded from dspmc.xml file.  make sure this file has all the correct settings and placed in c:\mach3 folder.  

there is a very nice editor Notepad++ which I use to edit dspmc.xml file.  download from http://sourceforge.net/projects/notepad-plus/files/

thanks

hi Peter,

I just sent you email with new AxisWorks software and firmware.

copy the exe files to c:\program files\dspmc folder.  also read the readme.txt file.
 
update the firmware with new version before running mach3 or axisworks.
 
you load the xml file in AxisWorks to tell it which axis is master and which is slave.  you select master axis when connecting to dspmc.   the new axisWorks will ARM pid for both master and slave.  when you download pid settings, it will download same pid values to both master and slave axis.  and when you save pid settings, they will be saved for both master and slave axis.

Let me know how it works.

thanks
Rufi

hi Xavier

having 0 in the max error I while I term is non zero is not correct.  there must be a limit on the I term error, otherwise oscillations are uncontrolled.

try these pid settings, and tweak them based on the response you see on the graph.  looks like you are getting very close to having a good tune settings.

P 5000
I 50
D 100000
Scale 1500
Max Error I 400
everything else is 0

also increase the distance from .1 to .25.

I dont have good experience with cff and cdff.  and I dont use them.

if you see still see too much oscillation, then decrease max err I.  

regards,
Rufi

hi Peter,

I think the best way is to have axisWorks allow tuning of master/slave axis setup.  I will try to add this feature in the next few days, hopefuly. 

are you using axis3 (a) as slave off x axis?

thanks
Rufi
