    Hello Mach3 supporters . I just bought complete Maxnc router system , it's running perpectly with MACH3 software but it has small problem , my models came out 30.9 percent biger then CAD models. Please someone tell me why and how to fix this problem.I 'm really appreciated for your help.Natcnc18.

Sounds like your steps per unit are set wrong, either that or you have a scaling of the axis, you will see that at the side of the Axis DROs, should be 1.00 for no scaling.

Hi, All

Hears a post by Art on MAXNC - CL pin out's

Re: [mach1mach2cnc] MAXNC 15-CL total frustration

Cary:

Sorry, your right. Thereis one on the OL, but not the CL.

I can tell you that if you check the MaxCL mode checkbox, you dont have to
worry about the motor pin settings from there.
The pinouts arent secret to my knowledge, theyve been published here before.

Since the motor pin settings are automatic, theres only a couple others to
worry about.. You need to turn on an output signal, ENABLE1 and set it to pin

16
and "low active", this controls the enable for the cl's hardware. You then

need
to turn on a ENABLE2 signal, and set it to pin 17, "Hi Active".

If thats all setup, then the unit shoudl work. Here's the CL pinout, but you
do not have to setup any motor outputs, as I said, they are automatic and you
can ignore the motor pin setup box altogether, other than making sure x,y,z

axis
are checked as enabled.

Ignore also Pin10, which can be used to make mach3 drive it in closed loop, it
isnt necessary on a properly setp system, so I usually dont mention that pin.

PIN ASSIGNMENTS FOR THE
MAXNC CL2 SOFTWARE

PRINTER PORT PIN ASSIGNMENT

1............... M3 OUTPUT (LOW=ON, PULSE FOR PWM)
2............... A AXIS (quadrature)
3............... A AXIS (quadrature)
4............... Y AXIS (quadrature)
5............... Y AXIS (quadrature)
6................X AXIS (quadrature)
7............... X AXIS (quadrature)
8............... Z AXIS (quadrature)
9............... Z AXIS (quadrature)
10.............. INPUT, MOVE ENABLE (LOW=NORMAL OPERATION, HIGH=STOP, SEE

NOTE)
11.............. INACTIVE FOR MILLS, NEG. LIMIT FOR MAXPATH(NORMAL LOW)
12.............. INPUT, HOME AND LIMIT SWITCH (NORMAL OPERATION LOW)
13.............. INPUT, G61 SWITCH SENSOR
14.............. M8 OUTPUT (LOW=ON)
15.............. NONE
16.............. OUTPUT, DISABLE POWER TO MOTORS (LOW=NORMAL, HIGH=DISABLE)
17.............. OUTPUT, RESET CONTROLLER (LOW=RESET, HIGH=NORMAL)
18.............. ALL SIGNALS GROUND
19 TO 25 ....... NONE


NOTE: MOVE ENABLE IS USED TO STOP THE COMPUTER STREAM OF CODES UNTIL THE SERVO
MOTORS CATCH UP. ON TIME-OUT IT WILL PRODUCE A SERVO ERROR.

EXAMPLE TRUE TABLE FOR THE 'X' AXIS QUADRATURE (TYP. FOR OTHER AXES}

PIN ..... | 6 | 7 |
------------
SEQUENCE ------------
1 | 0 | 0 |
2 | 0 | 1 |
3 | 1 | 1 |
4 | 1 | 0 |

Thanks,

Hi Chip
Thanks for the help.
I'll try to configure like Art examples.
Thanks for the reply.

I've been trying to get these specs out of MaxNC for 3 days!  Thank you for posting them!  Do you know the resolution of the encoders and the lead of the screws on the axes?
