General Mach Discussion / Re: axis calibration problem

Could it be that there is some tightness or binding in the threaded rods which is greater in one direction than the other ?

The Visual Basic version used is Cypress Enable and the commands and syntax in PDF format can be downloaded from here;

I think you need to return to what Terry said earlier;

"From the MDI screen type G31 X-2 F10 (followed by return) . The machine should start moving in the X- direction then trip the probe with your finger to see if it stops".

If the machine does not move, then we need to establish why.
Does the X Axis DRO indicate the move ?

Brian,

If you are measuring the voltage output from the computers parallel port then connect the multimeter between GND (0 Volts) and an Axis direction pin. The voltage should change between 5 volts (or 3.3 Volts) when the axis is jogged in one direction and 0 Volts when the axis is jogged in the other direction.
(the C10 can accept 3.3 Volt or 5 Volt inputs).

The problem you have at the moment is that the Digitize LED is defined on the Mach Screen as OemLED 825 and the Ajax instructions say that it writes the 'point of contact' to DRO1999. As it stands this will not illuminate any LED's on the Mach screen.
Somewhere there is an Ajax probing script (or routine for using a probe) which translates this DRO1999 into something that Mach recognises as the point of contact.

I have not used it but it May be worth taking a look at this http://www.razordance.co.uk/probe25D.htm

I think you are right Terry, even the guys on the Ajax forum don't really seem to know the answer to this one. This is why I would like to see the probing routine to find out how it interprets and applies the DRO 1999.

I am a long way from being a computer expert in fact a long way from being an expert on anything but I think the onboard graphics makes the processor multi task with a different priority to what Mach requires so everything gets screwed up.
Here in the UK we have Car Boot Sales every weekend and second user PCI graphics cards cost peanuts so it is cheap to try and if it doesn't work well nothing lost.
A plug-in graphics card  usually works as long as the onboard graphics can be disabled in the BIOS and it can be as old as you like (as long as it matches the slot voltage) because it only has to provide an 800 x 600 display as minimum - surely you must be able to borrow one to try ?

Sorry Buddy, looks like you need a different PC.
Alternately, you could consider using an external motion controller such as Smooth Stepper et al.
