Homing the machine.
« on: November 22, 2009, 04:04:26 PM »
I just converted my Chinese bought router from a pendant operated to a Mach 3 operated machine. I installed a C11G board from CNC4PC and all looks good. When I try to "Ref all home" the machine, the X and Y axis DRO's turn to zero (without the axis moving) and the Z just stays at the same value.
What do I have to set up to get the machine to home properly?

Martyn.

You need to have the Home switches enabled in Ports and Pins, Inputs.

Hood,
I did that, at least I think I did. X is on input 11, Y is on 12, and Z is on 13. Did I miss something?

make sure you have them enabled, if you do then attach your xml and I will have a look.

When I make the switches, the green square lights up in the diagnostics screen.

If you are using a custom screenset then check the correct script is in the Ref All button. If you are using the standard screenset then attach your xml and I will have a look.

I am using the standard screen set. What is the XML and how do I get it?

It is your profile settings file. If you are using the standard Mach3Mill profile it will be in your main Mach3 folder and will be called Mach3Mill.xml. If you have a custom profile it will be named the same as your profiles name.
You will need to copy it from the Mach3 folder to your desktop and then rename, suggest Marwellca.xml, this is because the forum will only allow one instance of a file to be uploaded and there will already be a Mach3Mill.xml.
 To attach to a post use the additional options button on the reply page and browse to the location of the renamed xml and attach.

Seems to be working fine here, try increasing the Debounce Interval on the General Config page. Set it to 2000 and see if that helps. If it does then reduce until you again get the problem then increase slightly until it goes away again.
If the debounce helps then it means you have noise in your home switch wiring, it is always best to have 5v signal wiring shielded and properly grounded.
