Hi, Finally got to startup but no motors running, I have tried all the suggested info from machsupport but no joy, my first thought was the Stepper motor PSU I got from ebay was 24volts 15amps BUT it wasn't after checking realized they sent me a 12volt 30amp OK but should still have worked, the steppers Drivers are TB6600 and BOB is an ECG-Savebase, first thought was BOB PCGND needs connecting to motor PSU GND but then saw schematic showing opto-coupled inside TB6600 so +5V goes to all +ve on TB6600 and connections from BOB Pulse Dir go to -ve of TB6600.
I then put a scope on BOB output connections and jogged X,Y,Z I did have some signals on PULSE output a train of about 10 pulses then a couple of second gap and again then same then a gap of about 10 seconds and again pulses high varied from 5V to about 2v, the signal on DIR went from 0v to 5v when jogging from X Left to X right and same on all others, so should I be able to see a pulsed signal from these PULSE output, my scope connection was from PC 5V connection and one of the output connections.
Checked Jog which is 50%
Parallel pins are 2,3 X axis 3,4 Y axis 5,6 Z axis
Also tried Enable active Low/High which I have on pin 14 no diffference.

Grateful for any help.

Regards John

Made error on Parallel pins should read 2,3 X axis 4,5 Y Axis 6,7 Z Axis.

Hi John,

If you attach your <profile> .xml file (the one from your Mach3 folder) we can check your set-up. Copy the .xml file and rename it to john40131.xml before attaching.

Hi thanks for quick reply, sorry to be a pain.
I take you mean the Mach3mill.xml file I have renamed.

Also looked at pulses from Parallel port and they are very sharp pulses and the BOB seems to give same, thought it would have been more like a square wave.

I read another thread about motors not running and was asking about parallel port, mine is on board was 0x378, I tried to put a Dynamode PCI Parallel card I have but cant find drivers for that so binned that idea.

John

Hi,
what sort of PC are you using? What version of Windows is it running? Have you run DriverTest.exe?

Hi John,

Just checked your .xml and cannot find anything really bad. Just a couple of suggestions...

Uncheck A Axis is Angular (General Config).
In Motor Tuning set Step Pulse to 2 minimum & save change.
Try changing Step Pulse to Active Low in Motor Outputs.
Try changing Enable1 to Active High in Output Signals.

Change just one item at a time and try it before changing another item - you know the fault-finding drill.

(Your Velocity and Accelerations are low but that’s OK at this stage, they can be increased later).

I am sure you are aware of this but if you are using an OS later than Win7 or 64 bit then it will never work with the LPT parallel port – you will need an external motion controller.

Tweakie.

Thanks for help.
Joeaverage...My machine is home built from an older MB which has a parallel port on board :-

MB Asus M2N68-AM Plus
Memory 2gb Corsair XMS DDR2
CPU AMD Athlon 7750 Dual Core 2.71ghz
Hard Drive SSD 128gb
OS Windows 7 32bit service pack 1
Checking Bios
Parallel port Settings
Address 378
IRQ (IRQ7)
Set to Normal, other options are EPP,ECP and EPP + ECP

I did a Driver test, strange would only work under administrator, posted pics.

I need to replace this power supply which was sent in error before I go any further only PSU I got was a 24v 3.2amp which I tried but could smell something getting hot so turned off.

Regards John

Hi,
well the PC and parallel port certainly look fine.

What breakout board are you using? Can you post a pic and maybe the manual?

Craig

Hi,

it suppose to be ECG-SAVEBASE but put PDF file of board etc.

Regards John
