dspMC/IP Motion Controller / Re: Repeating

Have you tried increasing the encoder debounce setting in the plugin config system tab?  that will help remove noise on the encoder lines and avoid position loss.

dspMC/IP Motion Controller / Re: DSPMC/IP V2 using more inputs and outputs than defined in MACH3

« on: December 26, 2011, 12:27:44 AM »

we have mapped the 64 inputs to a range of User LEDs.   this feature is available in the newer plugin. will upload it in the next few days.   the release notes will have info on the LED numbers to use.

sorry the stepper outputs are not yet available.  we do want to add stepper outputs, but I dont know when it may happen.

We will be releasing a new board named HiCON with step/dir outputs.  Will let you know when it is released.

dspMC/IP Motion Controller / Re: New Win7 install not connecting

« on: June 26, 2011, 04:46:07 PM »

try connecting to a switch with builtin DHCP server (eg linksys wrt54g).  so on the switch, you will have the PC and DSPMC hooked up.   both PC and DSPMC will get automatic IP address from the server.

also, in the windows firewall, try adding c:\mach3\mach3.exe in the allowed inbound and outbound rules.

can you access the dspmc via the Upgrade Tool search button?

dspMC/IP Motion Controller / Re: Output Issue

« on: June 26, 2011, 04:35:28 PM »

are you sure this output is not controlled by mach3 also?  you can look at the debug window and see a message like: Outputs Changed to xyz,  where xyz is the 32 bit hex value for the 32 outputs on the DSPMC.  it will tell you what mach3 is trying to do on the outputs.  hope this will help.

mach3 update rate is 10Hz (100ms period), so the outputs cannot toggle faster than that.  if you want more precise timing control of I/O,  you can use the dspMacro feature.  

e.g. the following dspMacro code turns on output 17 for 25 millisec

SetDSPData( 40+17, 1 )  :REM turn on output 17

StartTimer(0, 25) :REM Start Timer 0 for 25 mSec

2010
if TimerDone(0) = 0 then goto 2010 :Rem Wait for Timer 0 to get Done

SetDSPData( 40+17, 0 )  :REM turn off output 17


the dspMacro runs inside the DSPMC controller.  there are some DROs and LED that are shared between mach3 and DSPMC, and are used to command the dspMacro and move information back and forth.   If you like to explore this option, let me know your email and I will send you more info and other files needed.

dspMC/IP Motion Controller / Re: How to configure a MPG

« on: April 09, 2011, 02:43:18 PM »

are you using the latest plugin and firmware available on the web page www.vitalsystem.com/dspmc?  you do not need to edit any file.  all configuration is done inside the plugin.  read the mach3 chapter in the user manual.

dspMC/IP Motion Controller / Re: Research For My upcoming Build

« on: February 17, 2011, 12:16:04 AM »

here is some info I got sometime ago in 08:
------------------------------------------------------------

I assume that you have 3 sets of factory set DC Drives for those particular DC Motors.
Now you want to tune Drive and Motor with DSPMC Motion Control System.
 
Connect Motor with Drive and Motor Techo to Drive Techo Input, same as it was connected
in the Orignal Milling Machine.
 
According to FANUC, Input signal to the drive is called "Vcmd" Velocity Command.
Connect Vcmd pin of the connector to the ground or 0 V.
Connect Power to the Drive, same as it was connected in the Orignal Milling Machine.
 
Enable the Drive Enable input pin.
 
Now your Drive and Motor are energised, but due to 0V velocity input the Motor should not move. But if motor turns, then your drive have Zero Error.
 
There is Zero Adjust Varable on the FANUC Drive Card, you can adjust this for minimum
Zero Error.
 
You can find the drive Input Connector  Detail on the Internet by Google.
 
Now disconnect the Vcmd from 0V and connect to the DAC out of DSPMC
 
Now you should check for maximum Vcmd allowed, if it is 1.0V, then you have to reduce
DSPMC DAC output by a factor of 10 by using 10k Potmeter.
 
Now you are ready to tune Your Drive & Motor with DSPMC.
 
Make a fix move of 100mm and check the error on the respected Axis. Change the
Propotional, Integral and Differential Gain parameter slowly and observe the direction
of Error.Increase the speed and repeat the above procedure to minimise the error.

analog drives with +-10v torque or speed control are compatible with DSPMC.  I beleive most Fanuc drives are analog.  you also need differential encoder feedback.  many people have successfuly retrofitted thier machine since 2008, and I am sure some of them used the old Fanuc drives.
