General Mach Discussion / Re: HELP pleeeeeese Z axis problem !!!!

« on: August 06, 2007, 03:43:46 PM »

this is the controller info belowfor the cnc machine. I dont run a seperate power supply just through the CPU. The problem is always the Z axis and usually happens when it tries to retract upwards at the end of a cut so not necassarily when using all 3 axis at same time. I have 2 controllers  and they are both the same so it cant be a faulty one.



Controller for S-400, S-720 and S-1000:

Appropriate 1/8 Microstep Controller 4 channel:

4 channel controller
Power up to 2,1A per Phase
4 connections per motor, 1 connection for. 4 end or emergencu switches
connection to PC-parallelport
Microstep controller 1/8 Step
„Sleep-Function“ for energy saving in standby mode
Safety device for high overvoltage points
Power pack
ALU cooling device / 2 ventilators, 80 and 50 .
Option to connect 5 different end or reference switches, and emergency switch
All connections for motors and endswitch -  9 Pol sub D.

still having big problems with this  so if anyone has anymore ideas I can try as the machine is pretty worthless as a production item operating like this..

ok heres what I have done since:

*Got a higher rated Z axis motor-didnt fix the problem.
*swapped z and y drives over and still does it.
*contacted manufacturer and they reckon its some software config issue?? any ideas. The standard software is PCNC which is not very good to me so I havnt tried it but they reckon its perfect with that... IM STUMPED

  ooh and I did try taking putting a cooling fan on drivers and no luck!!!

I took the y drive plug out of the controller and swapped it with the Z plug on the front of the control box and then jogged z using what would normally be the y quick keys. problem didnt occur in z but does now appear in y. I didnt physically shift any wires inside 

 can I tell what definately needs to be where using a voltmeter?

x axis is active low, other 2 arent.

I just swapped the y and z axis drives around in the control box and it doesnt do it anymore? problem shifts.. Could it be wired incorectly in the control box for some reason?

It does have seperately wired drives inside the controller, 2 for the x motors and 1 each for the Z. Funny thing is the x and y are wired the same colours in order but the z is not wired in the same order. I dont want to blow the thing up as this is how it came!!

On output signals in diagnostics enable 1 has a red light on, not sure if this is significant..

A problem with the Z axis is driving me totally mad. I have a 3 axis cnc router and after 5 or 10 minutes of running a program the Z axis stalls when it tries to make a +ve move and just makes a buzzing noise ie no steps. I let it be for half an hour it works and then repeats the problem... I have tried everything (no real help from HEIZ cnc in Germany) and even put a bigger motor on to no avail. It is worse in hot weather??

I have it running through a pci parallel port on my cpu and after checking the pins directly out of the computer port for voltage here is what I get:

X axis pin 2 direction   5v
X axis pin 3 step         5v

Y axis pin 4 direction   5v
Y axis pin 5 step         5v

Z axis pin 6 direction   5v
Z axis pin 7 step         0v ??

I cant understand why I get 0v on step and the motor still goes, is this the problem? pin 1 is spare and is 5v but I am not sure how to swap everything.

Any help would be much appreciated

I swapped the actual wiring out of the controller?

General Mach Discussion / HELP!! problem with stepper motors/controller

« on: March 24, 2007, 01:46:20 PM »

when running a program the Z axis would after 5 or 10mins lose steps on the way up almost like it didnt have enough torque and was grinding. This caused the dro and axis to go out of sync and ruin my work. I have just swopped the Z and Y axis controls over and now the Y axis does it and the Z works perfectly. What could this be? Is it something to do with the pins I am using? I have a good spec PC with and am running it through a PCI parallel port. It is driving me crazy as its my only production machine!!! Help

I have been running mach3 on my laptop for the last 6 months no problems. I have just got a dell desktop running windows 2000 professional and put all the same parameters in an it goes mental. Motors are just jumping all over the place, I cant leave it on. Driver test on dell looks perfect. What is wrong with this setup??  ;
