Hi, Steve

Direction is controlled with the dir. pin being ether held high or low on each axis then the step pin is pulsed to move the axis the desired amount.

3 axises 6 pins and common Ground.

Hi, Klaus

In Mach3\macros\"the porfile your using"\Tool3.dat, Delete it or re-name it and restart Mach3 then recheck it, Apply OK, Check in again after another restart of Mach3.


General Mach Discussion / ab key Jog popup pendant ?

Hi, Nicolas

Never seen that happen, What happens if you press the opposite arrow key and then try the original one again ?

Dose it just happen on one axis ?

Have you used the Jog Pendant ("Tab" key pop-up) ?


Hi, Manmardam

Maybe you need a pull down or pull up resistor 1000 ohm's or so on the puls pin's, What do you think Hood, Maybe a noise issue.

Hi, Steve

To test out your current stepper system,  All you need Access to is the Step & Direction Pin's and Ground terminals and give it a shot.

On the pendant you emailed me about, I'm pretty sure you'll need to feed hold to change the z height.

Hi, Rich

Post an example of your problem dxf.

LazyCam should re-order your chains best it can from the origin marker position with Optimize button, Doing insides cut's then outsides  But in the end it should post the code from the top to bottom as listed in the Project Tab, Chain # can be moved around to your preference of cut.

Hi, Mike

Give this G-code file a shot, I put some pre-ambles in the top of your code.

Hi, Brian

Pic's below should get you started, There are a couple of ways to set up Steps Per, Hears 1 way, Determine the number of steps it takes to turn 1 complete turn and divide it by 360, That will give you steps per "Deg.", Enter it as your Steps per value in motor tuning.

Example: Stepper motor 200 steps X 10 micro step driver = 2,000 X 72 turn rot. table = 144,000 steps for 1 turn / 360 = 400 steps per Deg.

It all sounds confusing, Give it a shot and ask more Question's as needed.


Hi, Sn96

Mach3 will run it fine, Sherline cont is a step & dir, Hears the port pin-out's.

DB25 pin out:

    1 - Input from EMC (may be ignored in other systems)
    2 - X Direction
    3 - X Step
    4 - Y Direction
    5 - Y Step
    6 - Z Direction
    7 - Z Step
    8 - A Direction
    9 - A Step
    10 - NC
    11 - Output to EMC (may be ignored in other systems)
    12 - Output to EMC, XYZ home (may be ignored in other systems)
    13 - NC
    14 - Input from EMC, C1 (may be ignored in other systems)
    15 - NC
    16 - Input from EMC, C2 (may be ignored in other systems)
    17 - NC
    18-25 - Ground
