General Mach Discussion / Re: Is it the movement speed of the system?
« on: July 31, 2007, 06:35:05 PM »
I think I found the same problem.
When using mach the computer slows down. Literally. Every second on the clock is around 15 real seconds.
Everything just slows down. Mach only updates the DRO once every second.
Even the update of the task manager in windows slows down.
Ill be back after a restart.

Sorry I didn't see that. It is a brilliant Idea.
Maybe we shoud migrate to that thread.

General Mach Discussion / Automatic touching
« on: July 27, 2007, 01:18:52 PM »
I was just reading the manual and came to the bit about touching.
It seems timeconsuming and hazardus at best so why not figure out something less prone to breaking a tool than a steel plate.

So I came up with the idea of modifying the digitizing probe.
The same ide but instead of using a shaft with a ball at the end there would be a flat surface cloase to the base. And obviously upside down. This has the benefit over a simple switch that it reacts with off center tools and is more accurate. I have a few other simple ideas for switches as well.

The idea is to mount the sensor at a fixed position on the table so that Mach can be asked move there to compensate for the tool all by itself.

I have not heard of anyone that does this so I thought it would be a nice feature. I would certanly want it.
However I don't even have a CNC mill or router yet to I can't test the idea.

Not sure what a 3rd order planner is but I'm sure i want one. Go for it!
I think that Mach is all about user friendly-ness and I have heard a lot of things about Linux but user friendly is not one of them.

@Whacko: Now that is funny! I would guess that the system did not like the hardware or some driver.
ABB has been using 2k for many years and has run sp2 despite there being a sp4 released. Just because their policy did not allow it. They where and still are very strict about what they allow on their different machines because they spent a lot of time and money testing and evaluet different setups and programs. That way the systems where rock solid and nearly never had any problems.

The cost of windows is the only downside I can see. But if you buy a computer from a store you don't need to thing about that ether.

Did you know that XP runs some of the ATMs here in Sweden? I have never heard of a problem that was XPs fault. Altho we have made quite a few jokes about it. (and no it's not the kind of ATM that you can use MS paint on, these are secure)
2000 has been used for a long time in ATM aswell without a problem.

Anyway, my point is that if you treat windows properly it won't fail on it's own.

If only IBM would have been smarter. Then we would be using OS2 and not caring about instability. I have seen servers running OS2 for over 10 years without software faliure and still do. Getting tossed out only becuse the hardware itself is getting old now.

I don't know why I defend windows in this instance because I hate Micro$oft and what they do. I dissaprove that Gates stole the ideas not from Apple but from IBM during the time he worked there developing OS2. To bad he blew it with his own ideas. Neverminde. I should walk away now.

How does the drivertest look? Does the Graph spike in any way? Is the cpu speed constant? Any fluctuation in puls speed?
What is your enery profile set to?

I just ran the driver thert on this laptop that I am writing this on and I can assure you that after I saw the graph it made I will never connect it to anything that moves. Unless large black squares can be seen as a good thing.

I would advice against USB to 'anything'
The guys that program and test industrial ABB robots went through with testing USB to COM to use with laptops etc. They found out that they where just not reliable enough. And when you work with robots that can pick up a car you have very low tolerance of error.

A proper PCI card might be desired anyway. Concidering that it's a lot cheaper to blow one of those than a motherboard.
Besides I would expect a PCI card to have a lot better amplifiers for the putputs creating a much nicer waveform. Onboard is probebly of lower quality as the printer has error handling to compensate for bad signal.

No problem.

I use spybot sd to remove startup things. Easier I think.

Never heard of NVIDA 256. Have you got the latest drivers from Nvidia?
I remember that someone had problems with their AMD cpu and the only thing that helped was getting the proper drivers from AMD and not what was supplied.
How does the driver test graph of mach look?

What motherboard do you have?
Latest drivers and BIOS for that?
Latest chipset drivers? (what chipset do you have?)
Latest soundcard drivers?

Have you tried the alternative driver for mach?

You don't need to shout.

Also Nvidia 256 sounds like onboard graphics. Try using a separate gfx card. Even the simplest one will do for testing.
make sure you disable the onboard after you load the real one in.

Your processor should not be the problem unless you have crappy drivers and even then it should be no problem.

What about changing the CPU? I can buy a Intel Celeron 3.06Ghz CPU for around 0„530 from a builder 2 miles from where I live but is this a simple case of unplugging one and plugging in the other thus bringing immortal life...

No.
And even if you could you would not want to.
I don't have the sockets in my head but they would probably not match. Even if they would the FSB would be to low.
I think it is 100 or 133Mhz for your computer and most computer today run at 800Mhz.

Most cheap systems that you can buy will work great.
You could probably find some used 1Ghz computers for free or very cheap.
