Hi Hood,
Well this is what I found.
put the DVM between pins 17 and 20.
Booted Mach3 and on MDI screen entered M3,M4,M5.
The voltage read 4.24v and did not change for any of the codes.
So the setup in Mach3 is wrong or the port/computer is faulty.

Are there any other test I can try to see if it a Mach3 config problem?

I have checked the voltage on pin17 but not at the port but at the xylotex card.
Using m3/m4 I could not detect any voltage change.
I will repeat this at the parallel port on the computer if I can get at the pins.
In checking Mach3 configs I noticed one 'strange' thing.
In the digispeed guide it is written, output 1 is chosento drive the enable line, it has been configured to act on pin 16 of the port.
In the illustration it shows pin14 used. My pin is set to pin14 but if I set it to pin16 it reverts to pin14.
Pin 14 is unused but the digispeed board is enabled ok!!!!
I am not sure what to make of that.

Will go and see if I can check the voltages at the parallel port

Hi Vmax,
The mill is fitted with a 130V DC motor and this is controlled by a Lenze534 speed controller.
It requires a 0-10volt signal for speed control and the direction is controlled by switching current direction using a power relay driven by the direction relay of the digispeed XL board.

Hopefully Mach3.mill.xml

Hi Hood, I am back again.

In setting up the outputs I am following the DigispeedXL User Guide, page 20, Spindle set-up tab.

This says 'M3&M4 commands are used to control the same output signal. For this example Output No1 is used.

I am trying to send my Xml file but experiencing difficulty - will keep trying

In P&P-spindle setup I have M3 output 1
                                       M4 output 1
spindle relays enabled.

To check other settings means a trip to the shop which I cannot manage until tomorrow.

Yes I am using the standard milll profile.
M3 macro says dospinCW while M4 says dospinCCW.
I am beginning to suspect some thing is wrong in ports & pins though so far I have not spotted it.

Yes Hood,
That is where they are.

Further to my previous post I see in Mach3/macros there are 2 files M3.mls and m4.mls.
Is that where they should be?.

Hood where are the M3/M4  macros. This is them first I have heard about having to add them.
I have checked the voltage on the (pin 17) Dir signal on the Xylotex board when entering M3/M4 on the MDI screen.
The voltage stayed the same at 4.40volts so it sounds as though the problem occurs upstream of the Digispeed board.

For vmax, I have checked the pins and they seem to be as I understand the manual.
