Mach 3 ports and pins problems,

[chris w]

It must be my fault that the channels are down I suppose it's all part of that very steep incline called the learning curve but I can't afford to take out another channel but I go steady and keep it simple, I will be posting again I am sure about the homes but the more I can do myself then it makes the maintenance of the machine less of a problem,
cheers.

Are the channels repairable does anyone know?

The homing switches are fitted and working on the x,y and z there is also a switch fitted on the a axis and as the a only clamps every 45 degs the switch "sees" when the a is clamped but the OEM had not connected the switch to anything so I want to use it to confirm the a axis has finished moving and the the z,x and y axes can continue with movements,
i can't figure out how to disable any movements in xyz until this switch is made, I can connect it to the inputs ok and see the switch working on diagnostic but what in Mach needs settings for this to work?
does anyone have experience of this?
thanks,

Do you mean you want to Halt XYZ from Homing until A axis finished Homing.?

If so then this is very easy all you need to do is change the Homing script. By default Mach starts with Z then Y then X then A.
To change then goto Operator menu and choose Edit Button Script. On the Screen the Ref All Home button will flash. Click on it and it will open the script editor.
Now move the line that says "DoButton( 25 )" to the top of the list. The sequence will then be A, Z, Y, X. The other axis won't move until the A axis finish.
