General Mach Discussion / Sticky Axis
« on: October 28, 2015, 11:46:10 PM »
I just re-installed my Mach3 system. All working fine, however when I cycle Mach3 it sets the X, Y and Z axes to zero, requiring recalibration.

In its previous incarnation the Z axis setting was sticky - whatever it was set to prior to Mach3 being cycled would survive.

Clearly I've not set something to allow Mach3 to "remember" the Z axis value. Problem is, what?

G-Code, CAD, and CAM discussions / Setting Z Floor
« on: October 06, 2015, 01:15:01 AM »
Is it possible to use Gcode to set a floor for the Z axis, below which it will not travel? A bit like a soft microswitch which sets the lower Z limit.

I want to stop the Z axis descending to where it could gouge the table.

General Mach Discussion / Re: Should I Earth the CNC Machine?

It's a regular ebay-sourced 6040 with Huan Yang VFD and spindle. Up to now I've made a possibly rash assumption that the spindle case would be earthed, and with the spindle being bolted to the frame that carried the earth thru.

However I do recall viewing some discussion on online forums about earth loops, and as I have an inkling what they are about I can see valid reasons for not adding an extra possible earth loop.

This is probably a stupidly insane question, however should the CNC machine be strapped to earth?

General Mach Discussion / Re: Problem Using Mach3

Hi Fred,

This type of problem is generally associated with the pickup of electrical noise on inputs wiring.
Try increasing the Debounce Interval to 2000 or so (Config / General Config page). If this improves the situation then check that all your inputs wiring (e-stop, limit, home, switches etc.) are properly screened and earthed.

Tweakie.
Actually I think you hit the nail on the thumb. This was a random problem and after I moved some of the equipment around physically it went away.

Thanks.

General Mach Discussion / Problem Using Mach3
« on: July 16, 2015, 01:10:21 AM »
I have a 6040 and am using Mach3. I have a random/intermittent problem which I hope others might be able to help with.

Sometimes when I try to traverse using X/Y controls Mach3 hits estop, I have to reset and continue. This sometimes happens whilst executing reference all axes. However once set up I can run a long gcode job without issue. So strangely this seems to be an issue involving short duration motor feeds.

Seems a bit odd so I'm not sure where to start looking.

Aha! Thanks for that!

General Mach Discussion / Where are Mach3 settimgs held?
« on: May 23, 2015, 05:45:27 PM »
I'm curious to know where Mach3 stores configuration settings? Is there an INI file for holdn parameters such as those defined on the Ports and Pins dialog?

The reason for asking is that I've just been thru the pain of re-installing Mach3 on a replacement PC, and I had several hours heartache defining the configuration parameters. If these values were held in an INI file or similar then I could keep a backup handy just in case I ever have to install Mach3 on new hardware.

General Mach Discussion / Re: Wrong Plug-In Installed

c\mach3\plugins\ESS_v10r2d1d.dll or what ever version of the ESS plug you have
That did it - thanks.

Thanks - could you possibly be a little more explicit? The ESS plug doesn't appear in the Windows program list so I can't delete from there. I assume this might be a file someplace.
