General Mach Discussion / Re: Auto Zero Z-axis Metric

Hi Fred,

The third line in the script determines the probe feed-rate (currently set at 50).

The line which raises the axis, after the ‘touch’, has been commented out so the axis should now touch and stay.

FAQs / Re: G1 Y... commands sometimes ignored

If your Mach3 Y axis DRO indicates the movement but the stepper motor does not move then you need to look at your wiring.
It could be a bad LPT cable (or connector) between your PC and controller or between the controller and stepper motor. The problem could also be within the controller itself so check everything (cables, connectors, wiring, etc.) thoroughly.

If your machine is setup in mm units and your Gcode has been prepared in Inch units then adding a G20 to the initialization string (or at the beginning) of your Gcode file should solve the problem.

When I try to make a cut it is about a 1/4"

Can you explain in more detail exactly what the problem is.

Hi Fred,

If it's not operating 100% reliably then, in my opinion, it would be unwise to use the Auto Zero function. The problem is that it may work perfectly until you are setting an expensive or delicate tool - and that's when it always fails.

Many of the Chinese motion controllers do not fully support the G31 function (as far as Mach3 is concerned) and unless they are prepared to offer customer support by updating their plugin there is little that can be done. Try contacting XHC to find out which version of Mach3 they recommend for using the G31 function (it may be an earlier version than the .062 which I suggested). If you don't have an XHC contact email then Alex He may be able to help  xhctech-alex@hotmail.com

Hi Alayax,

Welcome.

Install everything as per the vendor's instructions.

When you open Mach3 go into Help / About Mach3... if it says Licensed to: Demo Version then everything is OK. If it has a name and that name is not your name then you have installed a Pirate license.

If you have installed a Pirate license then the file   Mach1Lic.dat   must then be deleted from you Mach3 folder before you continue to use the Mach3 software.

Galil / Re: Random E-stops Doesnt Seem to be Noise Related?? Fix it and I'll pay you a BUCK!

Unfortunately there is no one answer that suits all situations – electrical noise (and I am sure that is the problem) is bit of a chameleon.
A couple of suggestions…

1) A single point (star) EARTH with all cable shields taken to this one point (shields left unconnected at their far ends).
2) RFI filters fitted to both the VFD supply input and the machine controller supply input.
3) 0.1uF capacitor fitted between each used breakout board switch Input and GND.
4) Routing input signal cables (switches, etc.) away from ac power cables.

I don’t suppose 10 bucks buys much Beer these days but that always seems to help me with problem solving.

Hi Fred,

The .066 version of Mach3 may be causing the issue but there is also the possibility that the XHC controller is not supporting the G31 command properly.

Download and install Mach3 version .062 ftp://anonymous:guest@ftp.machsupport.com/Mach3/Mach3Version3.043.062.exe (this can be installed over the top of your existing install). As a precaution make a safe copy of the <your profile>.xml file which contains your machine settings.
