Well Old dopey me.... It was Windows2000 after all and sadly it isn't supported for .Net 3.5.  :(


I've tried every trick I could find on the net to get it to install on Win2K and I haven't found one yet. Unfortunately I'm looking at a controller I just purchased that's apparently going to collect dust unless this app can be made to work with .Net 2.0.  I can't even get .Net 2.0 SP1 to install.

General Mach Discussion / Re: Missing steps

Fasten a pointer to the leadscrew and align it with a marker then move the axis and the pointer should be back in line when you go back to the start point.

In most cases its rapid moves that cause the loss of position, try increasing the acceleration time and reducing the velocity a small amount.


Wondered about this one too. I suppose this would be different if you are looking at pulses/linear movement distance vs lost steps.

I would think that once your axes calibration is setup correctly and any backlash has been accounted for you could run a test of several itreations of back and forth motion and see where the pointer lands. I'm not sure that you would/could call that "lost steps" or actually determine whether you do in fact have everything setup correctly.

Could you use a dial test indicator and quantify the amount moved based on the number of pulses sent? Does Mach have a means of showing the count of pulses sent that could be "zeroed" before hand and then make your move and see where you land with the actual DTI reading vs the expected DTI reading?

Sorry offhand I don't remember. Would be a nice feature though.


I found it when doing a search for "kernel speed adjust". The thread topic is showing as "step and direction spindle" and was started by "bondeoca" in the General Mach Discussion thread.

Looks like it was originally posted on April 30, 2007, 06:58:17 PM

Hope this helps.

Still not loading for me.

UPDATE! I can get to page two of the thread, but not back to page 1.

See if this will load for you (Page 2).

Sorry, that was for WinNT, not Win2000.

Not sure if this is the correct place to ask this but I have Win2000 on my PC that controls the machine. I notice on eBay that the controllers I'm looking at state "Compatible with XP, Vista & 7".

Before I buy one, I was wondering if anyone has ever used this type of device on this operating system (Windows2000)?

I have the Fang Gamepad by Ideazon and it works fine, but it's picked up as an HID (I believe). It states is will work on Windows 2000/XP Home/Professional/x64.


General Mach Discussion / Re: Mach3 Gcode Manual

I see you have the spindle dir set to Port 1 pin 17 and also the Chargepump set to same port and pin, just wondering if that could be an issue?

How'd you get so smart? <Grin>

Never noticed it before but it seems to have fixed the issue! I certainly wouldn't have made that change manually. Who knows?!

Running again... now I can get back to making that Double Rotating Bi-hydroxiplatinum Electrolytic Time Machine...  ;D

Thanks again!

I didn't make any changes manually. But the setup has been working fine for quite some time.  I just found out about MachProfileV2.08 Viewer so let me dig up some older xml files to compare.

General Mach Discussion / Jerky motion but only when running G-Code
« on: June 25, 2011, 01:08:50 PM »
Using the latest lock-down version (Version R3.043.022).
Have read various "Jerky" threads and made changes to CV mode.,
Looked at Kernel Speed which shows I could run higher but leaving at 25k for the moment.
Installed MachBlue and noticed issues when running a small snippet of code that simply moves in the x-axis.

The odd thing is I don't have any problem when moving from the MDI; the axis moves smooth as butter.

So I uninstalled Mach, but kept the xml file and reinstalled Version R3.043.022 and replaced the previous saved xml.

Still doing the same thing. Can maneuver with the keyboard smoothly, can type movement directly in MDI and again move smoothly.

But when I load the code the stepper jerks, the pulses continue and of course gets workpiece positioning out of whack.

I'm at a loss.  Any where I need to start?

Everything was working fine before MachBlue, but I don't think that was the culprit at all.

Can someone take a look at my xml please?

Thanks in advance,
