Hi, Peter

I'll try that again, Had it set that way once, But not set to "Off line", Just Power Light on Mode.

Getting an Illegal Data Value now so it must be talking at least, Progress !!!, Thanks Peter !!!

Need some examples on opening and closing a coil input and output, Or something other than "Illegal Data Value".

Just Stumbling Around Hear, Chip

This manual section E ModBus info: http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/1762-rm001_-en-p.pdf

Just VERY Lost at this Moment I Hope, Have updated the PLC to FRN 11 needs ver 8 or above to run modbus.

Hi, Sooperdrave

If you hit a limit switch in Mach the DRO's should stop , The Status: line should show the Limit info.

Dose your A axis cont. board have a Fault indication ?

Is it a stepper or servo ?

More info. would help

Thanks, Chip

Hi, Luis

Pin 1 is an output pin, You can use it to turn on your plasma cutter, Ports&Pins, Output Signals, Output#2, ("Check" Port#1, Pin #1, set Act/Low/High as Needed).

M3 will turn it on, M5 will turn it off, Need to use a small 5 volt relay(reed, miniature or Best a solid state relay}.

Hope this Helps, Chip

Hi, Jim

No, Win 2000,  XP or Vista on1ly.

With 8 wire stepper motors, You can connect them in "series" 1/2 Amp rating of motor or "parallel" full amp rating of motor.

Series would be  A, "A_C_",  C and B "B_D_"  D

Parallel would be "A C_" "A_C" and "B D_" , "B_ D"

No, Your stepper Board should have a "current" adjust on it, It should limit the volt's/Amp's to your steppers.

Adjust it to the your 2 to 4 volts, Measure the volt's across one of the stepper windings, The stepper's should be Hot to the touch ( be able to hold them in your hand for a little-bit before the "Ouch/Whoo" set's in.

Hope this Helps, Chip

Hi, Cory

Hears a post for LazyCam below, Put it in C:\Mach3 folder, I added G00 x0 y0 z0 and M30 to the end.

When you get ready to post Click Post then use Set Post Processor, Change to Test Mill Example.PST, zipped.

In the latest ver LC 2.61 it doesn't show it's loaded it but it is loaded, Click OK.

You can edit these posts with text editor, The code I added is at the bottom of the file.

Do an Air Cut First, These are old pst's, Looks OK hear air cut.

Hope this Helps, Chip

Hi, Dustin

Above, Tutorials, Documentation, Using Mach3Mill , Hears a shortcut to the Manuals.

http://www.machsupport.com/documentation/

"Steps Per", Number of pulses to your stepper cont. to move 1 inch, Looks like your pretty close, Just need to reduce the steps per value a little.

To calculate it, Number of steps it takes to turn the stepper motor one turn, std. full-step= 200, half-step= 400, 10 micro step=2000.

If your stepper motor is one turn, std. full-step= 200 X 10 turn ball screw = 2000 "steps per.", 10 micro step=2000 X 10 turn ball screw = 20,000

Or std. full-step= 200 X 10 turn ball screw X 2 to 1 reduction = 4000 "steps per."

"Velocity" is your top speed G00, With no lost steps, Make your moves 5-10 inches if possible, G00 X10.

"Acceleration" is from a stop to full speed or full speed to a stop, With no steps lost,Use G00 or F100 to test.

Reduce the values by 10% or so, "Velocity, Acceleration ", It's a balancing act Hear.

G01,2,3, "G01 x10 F1", Will override these speeds and run at 1 inch per minute

The Manuals have all the Info you need, It's a bit of a steep climb, But there is a Plato up there.

Hope this Helps, Chip
