General Mach Discussion / Re: Mach setup for C23 BOB relays

« on: March 18, 2016, 04:57:43 PM »

Digging a little deeper,  I shut the board down and applied 5v directly to the coils of each relay.  The relay assigned to pin 16 does switch, the other relay appears to be dead.  Though the pin 16 relay functions in this manner it does not operate via Mach and M3 command.

I'm stumped.

General Mach Discussion / Mach setup for C23 BOB relays

« on: March 17, 2016, 07:46:35 PM »

I'm trying to get Mach to operate the on-board relays of the C23 BOB to be used to for run and direction control on my VFD.

I M3 and M4 commands assigned to output 1 and 2 in spindle setup and the 'disable relay' box is unchecked.  Output 1 is assigned port 1-pin 16, output 2 is port 1-pin 1 as directed by CNC4PC documents. 

I cannot get the relays to switch.  I've been checking by measuring the ohms of the terminals.

I'm at a loss here...as I have been a few times already.  I'm ready to shovel all these magic boxes into my mill once this is solved.

Any assistance would be greatly appreciated.

Got it!  Not sure how...but it is now functioning.  Now to get the relays to wake up.

« on: March 16, 2016, 02:20:52 PM »

I'm setting up my C23 BOB controlled by Mach to operate the 0-10v analog output which will control the speed of my VFD...and it does.  The problem is I cannot get the analog output to produce over about 6.5v.  I can control the VFD but, through higher mathematics, I can only realize 65% of my max speed as evidenced by the frequency display (of about 75Hz) on the VFD.  I've messed with the spindle motor tuning every which way to no avail.

Yes, I do have 12v  feeding the analog system.

Any thoughts?

Cheers!

SmoothStepper USB / Re: USB SS output voltage

Thanks, Tweakie.  You made me examine the C23 board more closely.  I was drawn to the arrangement of the LED indicators on the C23 as they are paired on the board... 1,2 - 3,4 -5,6, etc.  It confused my wee brain.  Sometimes you can't see the forest...

Pin assignments are shifted and I can now begin laying pathways for the herds of electrons to invade unsuspecting, far off stepper controllers.

Cheers!

SmoothStepper USB / USB SS output voltage

« on: March 12, 2016, 12:53:26 PM »

I have a USB SS plugged into a CNC4PC C23 board.  It has never been hooked up to any devise.  I found that everything on the C23 works EXCEPT for the X axis step (pin 1 output) while inputting manually through Mach3 or the direction keys on the keyboard.  I finally sent the C23 back to CNC4PC and just got it back.  I haven't heard back from Arturo yet whether a fault was found or not but I am getting the same symptoms as before. 

I have pin 1 port 1 assigned to the X step.  Measuring the voltage on the SS pin 1 delivers 0.87v  while the step pins for Y and X axis deliver 1.125v. 

My question;  what is the output voltage of the SS supposed to be and could this be the issue with the X step not functioning?

Are my pin assignments incorrect?

I exchanged quite a few emails with Arturo before sending the C23 back for him to test.

Thanks for any insight.

General Mach Discussion / Building a new PC

« on: September 29, 2011, 11:51:24 AM »

I'm looking for some advice.  The PC I've been using to run Mach3 and my mill has died an I want to build a new one.  I'm not current with today's computers.  The one that died I built 10 years ago.

Does anyone have a good 'shopping list' to build a dedicated PC for Mach3?

It seems the z axis decided it needed 25400 steps per revolution.  I returned it back to 1000 and it appears to be happy.

I'll tinker with the motor tuning tomorrow but, is there a 'magic' kernel/velocity combo?  Is there a recommended kernel for a specific computer?  This was working nicely with Mikini's supplied configuration.

The DRO is 'usually' showing the actual movement.  The machine operates fine in manual mode with its pendant.  I've also lost Z axis control via the keyboard (page up/down).

I've found that if I command a Z1 and it only moves a portion of that command,  another command such as X2 will result in the Z moving more... but not always completing its journey.  It will do this even with the machine off line. 

I've re-downloaded Mach and have the same symptoms.  It might be time to plug the computer into a 440v line and toss it into a bucket of salt water.
