thanks for these suggestions but I need an output file that is ready to load into Mach3, c/w post processor.

General Mach Discussion / 3d 2 1/2d cam program
« on: January 10, 2013, 03:06:58 PM »
I am trying to find a program that takes dxf files and gives me G code.  Like visualmill but it is toooo expensive. I already have the 3d cad program just need to do G code for both3d and v groove engraving.  suggestions please some seem to do 3d an not engraving or engraving but not 3d, good quality is nice but at reasonable price.

General Mach Discussion / M6 Macro Simple?
« on: November 11, 2012, 03:26:29 PM »
Newbi!  Most of the posts re M6 are about complex tool changes I just want a simple move.  When it hits M6 I want it to move to G00 X-4 Y-4 so I can change the tool , then I will jog  Z down to the new zero reference, because the new tool length is different,  then I can jog Z up to clear stock and press start.   I think it will go back and run the finish path gcode?????My Gcode comes from visual mill
All the talk about edit M6start and M6end??? The only place I can find those files is in the "Macros" subfolder but they are M6.m1s  type files and they don't even open with notepad etc.
Where do I find the M6 macro?
Can I edit it and do what I want?  Where do I save the new macro so the program will jump to the macro when it sees M6??  
I'm sure many folks have already done this, its so simple but I can't find it
Thank you in advance

FIRST THANKYOU FOR YOUR INTEREST!  Dips are as follows, 1on,2on,3off,4on,5off,6off,7off,8off, 9off,( this is the default setting for 25,000)10off,11off,12off      second switches 1off,2off,3off,4on,5on,6on.   Kernal 45,000.  steps per 64000.  vel 40, accel 18.   The axis move at this setting but SLOOOOW.   When I used the old DOS system controller I had the ZETA4 driver set at 2000 steps per rev, that was 6on,7on,8off,9off,.   Motors are connected directly to the screw which is 5TPI
I am going to take a scope out and look at the pulse train,  I have a C10 board on the PP output
thank you
PS   BINGO   -I went back to your first reply and decided to try 200stepx10 or 2000 microsteps, I also set the pulse width to 5us, and seps per 10000, velocity 190, accel 100  and things started moving!!    so I am now close enough to start tuning etc.   don't know why I set the velocity at 190 to get approx 20ipm motion but I am close enough to start investigating.  THANK YOU

Sorry guys I am still not getting results, missing somthing.
SUPER KITTY suggested setting of 125,000 steps per, velocity =40, acceleration = 18.
I cannot get this combination, as soon as I enter the 125,000 the velocity goes to 12 , if I enter40 it just changes when I hit return
Now HOOD said the steps per unit should be 64,000,  not 125,000. I did up the Kernal to 45,000. What am I missing??
I have tried many combinations without sucess so I will give the system specs again just in case.
MOTOR is ---Compumotor ZETA 87-135 ( specs are on line at Compumotor site)  it says 200steps per  then in brackets sya 12,800 microsteps per rev.     Which number is the real number??
DRIVER is -----Compumotor ZETA4 driver (specs are on line at compumotor site) and these two are made to work together, they spec the motor right on the side of the driver.    The driver has many option via dip switches and I can set the "steps per rev" in the driver fromm 200 to 50,000.   25,000 is the default setting.
My axis screw rotates at approx 5rpm so my table is hardly moving but it moves reliably in both directions.
Is anyone else using Zeta drives?
The maddening thing is that my system runs fine, normal speeds, under my old DOS control but I am trying to upgrade to Mach 3.
I would gladly pay somone for their time if I could call somone for phone support.
Thank you!
Garth

General Mach Discussion / stepper motor speed
« on: October 29, 2012, 08:45:10 PM »
Trying to set up, configure?  Using ZETA 87-135 motors, ZETA4 Drives. These motors and drives are made for each other, I have used them on my previous DOS based system and they work fine. Now I want to go to Mach3. All 3 axis motors turn, both direction butTOOOOOOO slow.
Specs from compumotor say the 87-135 motor is 200s/rev or 12,800 microsteps/ rev. which number do I use in the Mach3 formula?   Mach3 is set at 25,000 and the ZETA4 drives are set at 25,000 steps per rev. ( this is the default setting for the drives).  My motors are connected directly to a 5TPI screw.  I want my router to move at  40ipm. I have tried to understand the formula for tuning but I cant get the numbers to add up or to look anything like the sample screens in the manual.
screw is 5TPI, to move 40 ipm, motor should turn at 40x5=200 rev/min????  I just cant seem to get that 200 number to fit into the mach3 formula???in the motor tuning section. Sorry but I must be missing somthing. Can someone give me approx numbers to put into the motor tuning screen to get me close?
Thank you

General Mach Discussion / just starting help Z axis DRO
« on: October 19, 2012, 11:15:16 PM »
I am just going thru the tutorials and evrything seems to work but when I run the sample files the X & Y DRO read outs change as expected but the Z axis DRO stays at OOOOOOO and never changes even when there is a new z position in the command line.    The white outline showing the tool position changes as the file is run thru but  the DRO. stays at zero.  I am upgrading from an old DOS based system and these screens seem great!
any help?
Thank you
