General Mach Discussion / Spindle Setup Special Funtions ?
« on: March 26, 2014, 07:15:07 AM »
Hello,

About Spindle Setup Special Funtions with PWM Control:


1.-
Reading the manual 5.3.6.7 Special Functionm say:
"Use Spindle feedback in sync mode should be unchecked."

That's all, nothing more.
So I can not understand the purpose of that function,
I would like to know about this


2.-
About "sync mode"

look for this, and did not find.
I can not understand the sync mode,
I need a glossary with Mach3 terminology
I would like to know about.

3.-
About Special Function: "Closed Loop Spindle Control"
I seek to know the frequency, the time between each pwm update.
how often the pwm is updated?

How do I calculate the time (frequency) of PWM updates ?
I would like to know about.


4.-
Reading this forum, I found something opposite:

http://www.cjh.com.au/PWM%20Spindle%20Control%20using%20Mach3.pdf

Say:

"Do not use Closed Loop Spindle Control.
 
Selecting “Use Spindle Feedback in Sync Modes” tells Mach3 to expect feedback pulses from the spindle.
Selecting this effectively puts Mach3 into a closed loop mode."


Thank related information.
I appreciate your time and attention.

General Mach Discussion / Re: Limit switch triggered. Which axis???
« on: September 23, 2013, 03:45:21 PM »
That's the problem:

1. - Use watchdog is disabled.

2. - I do not know which switch triggered.

The machine works normal, but randomly trigger this message and stop.

Appears noise, but it was 4 months working without problems,
with Debounce interval ats 500.

Now Debounce interval is 3000. Is that enough?

General Mach Discussion / Limit switch triggered. Which axis???
« on: September 15, 2013, 09:15:59 PM »
About this message "limit switch triggered"

I have the limit switchs NC.
Debounce interval 500 (then increments 250)
My last setup Debounce interval is 2750. Is that enough?

Something I want to know is:
Specifically. Which axis is the trigger?

The message "Limit switch triggered",
NOT SAY to me, the switch triggered.

That I can do to know the trigger axis?

I appreciate any related information.

Hello,

I want to know that is all that is needed to make a Smoothstepper with Arduino Mega2560 with ethernet shield.

PC with Windows XP and Mach3 working fine. Check.
Arduino Mega 2560 board, cables and connectors. Check.
Mach3 SDK.2.62.zip Check
Microsoft C++ Check
Library.h to drive step motors with acceleration and deceleration, multiple simultaneous steppers, etc. Check.

Know how to do it,  -NO CHECK-

Found sample code?

I appreciate any related information.

General Mach Discussion / Keygrabber deafult.grab file
« on: May 02, 2013, 07:42:55 PM »
Hello,

I lost my "installation file default" of keygrabber.

I need see the file Default.grab (Default).

I not have other PC to install the Mach3 and get the file default.

You can send me this one?

I appreciate your time and attention.

I setup the Spindle PWM and work.

But I wonder.
Why PWM signal does not accelerate or decelerate?

When I switch to M3,
immediately sends pulses of "S" (speed), without accelerating.

When I turn to M5,
immediately turn off the pulse train.

Mainly I'm interested in accelerating the switch.
for example with M3S15000

When I change M3S12000 speed, M3S14000, M3S16000 ... changing the pulse train without acceleration.

It is normal that sends Mach3 PWM signal without acceleration?

What I look for is a soft start motor.

Mach3 does not use the motor tuning acceleration values for the Spindle axis when generating the PWM signal through the parallel port.

That said the SmoothStepper does use it when generating the PWM output.

Cheers,

Peter

After trying several configurations,
I suspected: Mach3 ignored and no use some tuning values ​​for the Spindle.
Maybe not use all values ​​of motor tuning?

Then only work with Spindle SetUp, Motor Control:
Check use spindle motor output
Check PWM control.
PWM Base and minimum PWM
and that's all.

The motor tunning and setup is ignored by Mach3 (case Spindle). ???

Independently, moreover:
Of course I'm interested in very high quality pulse train.

So I need an FPGA board with wireless, cheap for a poor.

I'm in cheerful.

I appreciate your time and attention.

Hi Riphet,

I am no expert here but in all the cases I have seen...

The motor Acceleration and Deceleration times are specified parameters within the VFD manufacturers setup menu.

Once the CW run signal (M3 in Mach) is received by the VFD, the motor will accelerate up to the actual PWM requested speed over the pre-set time interval. The motor then follows a similar pre-set deceleration interval when the CW run signal (M5 in Mach) is removed.

Tweakie.

Thank you very much

I'm poor, I have no VFD.
Only use a simple triac with optocoupler.

General Mach Discussion / Re: Accuracy in Ref All Home
« on: January 08, 2013, 04:46:10 PM »
Thanks,

I'm looking for maximum precision Z-axis when Ref all home.

I understand that the ability to switch repeatability is essential,
(this is hardware).

I also wonder about Mach3,
Regardless of the limit switch,
(this is software).

About Mach3 setting,
About procedure (macro / script) in Ref All button home.

Is the 100% accuracy depends absolutely limit switch ?

Additionally,

Now I wonder how is the button Verify program,
the MDI screen wil (Sept. standard screen

Furthermore,

Now I wonder
What numbers eliminates the option of Config autozero, Homing / Limits?
Is the distance traveled by slowdown?

Is there a function similar to the tester:
GetVar (2002) 'get the exact point the probe was hit
But that is about HOME signal switch?

Additionally,

Now I wonder how is the script off button Verify in MDI screen(standard screen set).

My doubts are multiplied exponentially,
I appreciate your time and attention.

I would like to know about your experience with the switch mentioned.

You have used a switch as it says?

What is the accuracy you get with Mach3?

Then, no longer require daily calibration table?
