General Mach Discussion / hunting for something?

« on: June 21, 2007, 07:04:04 AM »

Guys,dont know if you can help.
computer:
  2.8 pentium galio motherboard NEC Powermate
512 ram
ITE PCI par.port card. (motherboard only gives out 3.5v)

happens on all versions of mach3.

When I first start up the computer and go into mach,it seems to be looking
for something because the vfd controller relays keep clicking about once every 3-4 seconds.
if the spindle motors running you can hear it blipping,but not stopping.
I run my suds system from a solid state relay and that goes on simultaniosly.
  This goes on for about 20-30 seconds and then stops.
This only happens the first time you open up mach.
it dosent do it again untill you restart the computer.
  There is no effect on the servo,s.
It dosent really cause problems its just annoying!

   Cheers

Hi,
 I have noticed eratic linear moves on both of my machines if the feed rare increases over 600mm pm.
they dont miss steps but kind of stops and waits for more pulses,I am 100% sure its software related
any Ideas?

General Mach Discussion / rotary dro

« on: February 16, 2007, 03:38:50 PM »

Hi,
   Hi Im trying to build a gyroscope using quadrilatiure encoders for positioning.
  could someone point me towards a freebe software which can act as a dro ,
via the parallel port.
I know i can do this within mach but Im looking for something really basic.
It will also need to work with XP,and not throw up a DOS type screen.
   Cheers

General Mach Discussion / Strange Behaviour

« on: February 11, 2007, 09:22:22 AM »

Hi,
  got a bit of a quirk on my machine,can anyone advise?
Ill describe the machine first
Computer:
Pentium 4, 3 gig,  256 ram, XP pro
onboard graphics, sound with netmos PCI parallel card.
latest licenced Mach3 running 25mhtz

machine:
home brew servo'ed Denford triac.
Gecko 340's
600 steps per mm acc/decc set at 150. max feed about 90% of available.
 There is bags of power from the servo's
Homan VFD spindle card
all slides free and easy, correctly adjusted with no stiffness or ware.
 shielded cables and earthed where needed
good driver test,dont suspect noise.

Problem:
  I use the machine daily in my buisness with alot of different
programs (small tool/pattern making)
  Very occasionally when halfway through a program it will kick out the y drive,
when doing a G00 x&y right at the end of the move.
 This problem is 100% repeatable at that point in the program.
The only way to stop it is to make that move seperate Xthen y,then its happy!
  Now the strange thing is if you program it to do the problem move only in a seperate little
program going back and forth,its fine it will do it all day,without kicking out.
  Any Ideas? ive seen this sort of thing with steppers (resonance problem)
but its got me beat,could it be something to do with the amount of ram being used by
the lookahead setting,mines set to the 20 lines?
  could it be that each axis has diferent gearing X3:1  Y4:1  Z3.5:1 (max reduction tooth wheel in available space)?

     Thanks in advance
   Tony
