General Mach Discussion / Re: X axis will ONLY move in one direction

« on: September 15, 2013, 01:46:34 PM »

Hi Gerry,

Ok the Voltage Test results when using the keyboard keys are as follows:

Pin 4:  -  Y-   =  3.30 v
Pin 4:  -  Y+  =  0.00 v

Pin 6:  -  Z-   =  3.30 v
Pin 6:  -  Z+  =  0.00 v

Ive checked the drivers for the PCI ECP Parallel Port and they are working properly and the driver is up to date.  Do you suspect the PCI card is faulty?
The Pci card I purchased for the Parallel Port is Brand NEW and the test Ive done appear to suggest that the card is functioning as expected.

I really appreciate your Help on this Gerry.

Kind Regards
John

Hi Gerry, guys

Here are my results from the voltage test.  The test was carried out by using the PINS at the end of the connected parallel cable. (Parallel cable still connected to the PC, via a PCI card and disconnected from the Heiz controller unit)

The set-up:

Pin 2   -    (my X axis control pin)
Pin 3   -    (my X axis step pin)
Pin 25 -     used as Ground

RESULTS:  (when using the Shuttle direction X- and X+ keys)

Pin 2:
X-   =   -0.01 V
X+  =   0.10 V

Pin 3:
X-   =  0.02 V
X+  =  0.02 V

Hope this helps Gerry.

Regards
John

Guys,

Just one other thing Ive come across is in the Motor-plug diagram attached where it stipulates: " if the spin direction is wrong it can be changed using the software.  Just thought it might help in someway.

Many Thanks for advice guys,

Jimthefish,  I have swapped the X and Y axis pins around as you suggest, however when operating the shuttle (via the tab key) when I depress the direction arrow keys on the shuttle the X axis still moves in only one direction.  (BOTH the Z and Y axis ..... even when the pins have been swapped, work in BOTH directions).  Jim bearing in mind this is ALL completely new to me, am I correct in thinking I do not have/use a BOB (Breakout Board) with my set-up?.

PC --- Linked to Heiz step controller unit via Parallel cable.  ---  Heiz step controller unit is then connected to the Heiz S-720 cnc machine via cables supplied.

Gerry,  Have now received a multi meter which I ordered in order to carry out your suggested Voltage test.  Could you please confirm in more detail what I should do exactly to check the voltage.  Gerry, do I check this 5 volts pins at the end of the Parallel cable after detaching it from the Step-Controller unit.  Or should I be removing the cable which feeds the X axis stepper motor at the OUTPUT end of the Heiz Step-Controller unit.  Also should Mach3 be operational during testing.

Sorry for being such a numb nuts ................  but the whole world of CNC is completely new to me.

Many, Many thanks for your patience and time.

John

General Mach Discussion / X axis will ONLY move in one direction

Hi Everyone,

SPECs:   Heiz S-720, Heiz control unit linked to PC via Parallel port and PCI card.      PC: running Windows 7 (32bit) and latest version MACH 3

I've setup MACH 3 to the best of my knowledge and checked things over and over, but whenever I Test the motors in (via the ARROW keys)  the X Axis will only move in one direction (X++).

However the X axis window on the Mach 3 interface, does indicate a X-- (negative number) as well as a X++ (positive number) when the left arrow and right arrow keys are depressed.

BOTH the Y and Z axis operate as expected when jogged by the up/down arrow keys and page-up/down keys respectively.

I've re-installed Mach 3 several times now and made sure I re-booted after installation, but the same problem exist.   


Any help or advice will be greatly appreciated.
Many Thanks
(Newbie)
