General Mach Discussion / Mach3 Motor Tuning Settings to Turbo CNC?

« on: July 27, 2012, 02:29:39 PM »

Hi,

What is the procedure to follow in order to take my direct values from Mach3(Velocity, Acceleration, Steps/Unit) and convert them to the required values for TurboCNC?

General Mach Discussion / G01 Arc no arc?

« on: July 25, 2012, 01:43:51 PM »

Hi,

My arc is not coming out as planned, it seems it just doing straight linear lines from point to point.

Here is the macro code I'm using:

' Arc #2

Dim x_start as Double 
Dim z_start as Double
Dim TextLine as String

x_start = 1.01
z_start = 1.240 ' 1.2 ' 1.240

For i= 1 to 24
   Code "G00 X1.0 Z1.25" ' 1.22
      While(IsMoving())
         Sleep(100)
      Wend
   Code "G00 X" & x_start & "Z1.25" ' 1.22
      While(IsMoving())
         Sleep(100)
      Wend
   Code "G01 X1.0 Z" & z_start & "I1.0 K1.0" ' K val?
      While(IsMoving())
         Sleep(100)
      Wend
      ' Msgbox "Arc #" & i & " done."
   x_start = x_start + 0.010
   z_start = z_start - 0.010
Next I

General Mach Discussion / Mach 3 Logic/TTL?

« on: July 23, 2012, 03:46:12 PM »

Hi,

Is there any way that you can setup a script in Mach to send a +5V TTL when the motor is not running? My stepper driver has a disable input, and because the steppers are very loud when not running(resonance) I'd like to have a +5V applied to this input when no axis are moving. Is this possible?

Thanks

General Mach Discussion / Closed Loop Spindle Control

« on: July 23, 2012, 02:36:03 PM »

Hi,

Is there a automated function within Mach3 to calculate the Proportional, Integral and Derivative values for my spindle? If not, is there a common formula that you can recommend?

Thanks

Show"N"Tell ( What you have made with your CNC machine.) / Cheaper alternative to the C11G Breadboard?

« on: July 23, 2012, 10:39:40 AM »

Hi,

I'm looking for a cheaper alternative to the C11G Breadboard($109.00). The only major advantage to this breadboard is the analog output(0-10V) that is controllable through Mach3. Is there a cheaper breadboard out there that has the ability to control a analog output for my spindle drive? Or the combination of a analog output and breadboard for $109.00 the best deal out there?

Thanks.

General Mach Discussion / Re: Mach3 Step/Dir Issue?

« on: July 20, 2012, 09:29:00 AM »

Hi,

I tried enabling the Sherline pulse method with no luck. I notice from looking at my step signal on  multimeter when I go to try to change to the direction that does not work the step signal will change from 5V to .6V once i've clicked the opposite direction button. I believe the step signal should be going directly to 0V to indicate that the direction has been reversed but for some reason it's sending out .6V. What is the problem here?

Thanks Hood I will try it tomorrow morning. What exactly does the Sherline pulse method do and have you heard of this happening before?

General Mach Discussion / Mach3 Step/Dir Issue?

« on: July 19, 2012, 03:35:57 PM »

Hi,

I'm currently trying to use a Linistepper V1 along side Mach3 to control 1 stepper motor. I have my step and dir signal going to the Linistepper driver and I am able to successfully and smoothly move/step the motor in one direction however when I try to move to the opposite direction(--) the motor gets loud and does move but very slowly.

What is odd is that if I switch the state of the "Step LowActiv" in the ports & pins / motor outputs tab I am able to move the motor in the direction that I previously couldnt, but once ive changed the step lowactiv state i am then unable to move in the other direction(++). This leads me to believe that Mach could be the issue.

Anyone bump into this before?

Hi,

After doing a fresh reboot the problem fixed itself, thanks!

Thats all you need to do so not sure why you have hit the line limit then.
If you attach your xml and your code I will see if I can replicate the problem here and hopefullt find the issue.

How do I configure a license, by simply placing it into the Mach3 directory? My Mach does state that it is licensed.
