General Mach Discussion / Z axis off, can't resolve the problem.
« on: October 02, 2016, 01:58:28 PM »
I've tried on two progams, backplotted and all my code is correct, but the cut depth is wrong on every file I load. The DRO will say I'm cutting at a depth of -0.750 but it's only cutting a depth of -0.384 (example). What in the world am I doing wrong? To be sure I calibrated Z axis and it's right on the money.

Any help would be appreciated.

This is a new one on me

Mach 3 seems to run great until I close the program, it'll crash every time except in safe mode.
Has anyone had this problem before?

Here's what comes up.

The problem seems to be caused by the following file;  atiok3x2.dll


Tech. Info:

*** STOP:  0x00000050  (0xE2AB1F6E, 0x00000000, 0xBF193275, 0x00000001)

***   atiok3x2.dll  -  address BF193275  base at  BF182000,  DATESTAMP  4b738974

I'm running Windows XP Pro SP3
Dell  Inspiron 600m Laptop

Intel (R) Pentium (R) M
Processor 1.60 GHz, 591 MHz
1.00 GB of Ram

Any help would be greatily appreciated.

Thanks Hood,

 I'll give it a try. Does changing the steps change the speed of the motors?
I also noticed my sliders don't work in the Motor Tuning dialog box, "motors won't turn" to fine tune. On top of that "jog" doesn't either. Could my VistaCNC Pendent have anything to do with it?

Thanks for all your help,


Ok, threads are 20 tpi. Stepping 1/8, they are direct drive.

Motor Tuning;

Steps Per;  2000

Velocity;  120

Accel;    8

Step Pulse;  0

Everything seams to work good at this setting

Dir Pulse;  0

Thanks, Hood,

I'm using the Keling CNC 3 Axis Package with 425 oz-in motors with the KL-4030 Bipolar drivers with the 36V /8.8A Power Supply     


On a Sherline 2000 Milling machine. Should pretty much straight forward.

I tried to tune the motors using the "Motor Tuning" Dialog box, but when I move the sliders nothing happens...I think this may be part of the problem, just don't know.

The setup I have is;
Mach3 w/ LazyCam
Keling Motors & drivers
Vista CNC Pendent w/ iMach Screen set

Thanks for your help,


General Mach Discussion / How do match dimensions from Mach to Mill??
« on: April 13, 2009, 06:21:49 PM »

Hi everyone,

I'm tryng to setup my Mach3 and everything is great except the deminsions. When I load the roadrunner file in Mach3 and send it to my mill it comes out about the size of a pencil lead. So to test this I loaded a 3" circle file and on the milling machine it comes out a 1/4" in size. What in the world am I doing wrong. I'm very new at this so please be kind ;D
