General Mach Discussion / Re: Autostart profile in windows xp
« on: February 09, 2011, 04:03:41 PM »
@ Hood,

OEPS... totally forgot about this topic (again)......

I just tried this , also in the command line , but it didn't work , again an error message.

This is the line I used:
C:\Program Files\cnc\mach3\Mach3.exe/ pcnccor

"cnccor" is the profile I click when I get the little interface when I start Mach3.
Mach3 is in the correct folder C:\Program Files\cnc\mach3\Mach3.exe , when I past this in the command line mach 3 starts

Anyone has a clue why the / pcnccor doesn't work? (I also tried "Mach3.exe/ pcnccor , Mach3.exe\ pcnccor, Mach3.exe \pcnccor, Mach3.exe /pcnccor, all to no avail)

Thanks again ,

Hey Hood, thanks for the reply, but unfortunately , it doesn't work, I get an error message. Attach a photo from the path and the error message. My profile is called cnccor.

Many thanks,

Hi all,

When I first installed Mach3 I had a desktop icon of my profile, but I deleted it :-/.
Now I have a dedicated computer for my machine and want windows xp to start up automatically with my profile when the computer starts up.

Using the startup option in windows xp is not a problem, but which program do I have to start? When I select "mach3.exe" an option screen appears,


No luck so far :-(

Today I have tested:

-new video card (from the old PC)
-installed windows XP as "standard pc"
-Hyper threading off (in bios)

no change :-(

When I installed mach 3 with windows xp installed as "standard pc" MAch 3 didn't work, it run, but the ax-es remained where they were, also the dro's didn't move/change.

Next to that I tried most of the items described in  :"OPTIMIZE.TXT" but also no joy.

I might try a new paralellport instead of the onboard parallel port, but have to go to a computer shop first.


@docltf: don't worry about the different speeds.The video without the thumbs was the the very very first test with my machine, obviously i run it at extremely low speed. The video I posted was just for reference in the sound. (so you could easily identify the sounds difference).  I really can not imagine that 3 steppenmotors can have a defect at the same time, especially when i changed another crucial component in the system. I only suspect it has something to do with the new computer, that's the only thing which make sense.

Although i have to say I know Murphy (from murphy's law) very well...... so... :-) I will keep your solution in the back of my head, but will only check this at a last resort, when nothing helps with the new computer I will first build up my old computer again.

@ Rich: Thanks for the input, I will first check the pulse. I have an older video card still at home, it should be no problem to put that one in.

-How do I check the output V, just put a voltmeter in the hole?
-which mode should the driver be (epp, ecp............)?
- how do I optimize the computer/windows (xp) for mach3.
-my brother in law came with a solution putting in a new/external parallelport instead of the build one......could that be a solution?

thanks people,

ps unfortunately not at home untill next wednesday, the troubleshooting has to wait :-(

@ docltf:  and than what?   (As said in the first post, this strange noise came a day after I installed a new computer. and is also on all axis. I am 99.99% sure it has only something to do with the new computer and not a mechanical defect)  Before I put back the old computer together :-( I want first to explore all possibilities to get this new baby to work well with my cnc machine.


hey Guys,

The mainboard is a MSI PM8M-V series:

Installed is a 3ghz intell processor.

@ Rich  & Jeff_birt: it has a oboard graphic card, I will try to replace it with an external one. Hope this helps.
I haven't checked the pulse stream, will do that as soon as I am home again next week.
It was a fresh install of windows XP
What do you mean with the optimization with mach?
No clue what the voltage is of the parallelport

@ Lemo: no clue what you're talking about....... all a mystery for me.... what I understand for you , there is no solution , just to go back to my previous (slow) computer.

Which mode needs the parallel port in (SPP,EPP,ECP,ECP +EPP or normal)?

all thanks for the input, I will let you know the outcome at the end of next week.


@ Sam: youtube link is updated. 

Sam, what dou you mean with the gecko drivers, software drivers or are those the steppenmotor drivers (hardware)?   If that's the case, I think it will be easier to switch back to my old computer ......although I like the extra speed.

I tried different modes on the parallelport:

but no succes

:-( Cor

Hello people,

I just got a new computer from my brother in law for my homebuild cnc machine, instead of a slow Pentium AMD 750 thingy I now have a Pentium 4 fast thingy :-)

But when I run the axes there is a strange noise from the steppenmotors.... I am sure it has something to do with the switch of the computers, not with the cnc machine itself.

But what can be wrong and is there a solution?

here a small movie with the strange noise:

Here a movie as a reference how it was before (movie was the first test when the machine was finished)

hope someone can help,

many thanks,

General Mach Discussion / connecting vacuum cleaner to mach 3
« on: March 30, 2009, 04:15:18 PM »
Hi guys,

I want to connect my vacuum cleaner to mach 3 so it turns on and off during running the program.  The only way is to do it via the mist/flood option? (not going to use this for wood :-)  Or is there a better way?

If yes, the code M7/8 and M9 I have to put in manually in lazycam or can that be done automatically?

When I check the option "coollant" in lazycam just before posting the g-code it just puts in the M9 in the beginning but never switch on the M7 or M8.

Thanks again for the help,
