General Mach Discussion / Re: Unspecified failure message
« on: August 29, 2007, 07:45:26 PM »
Hi All,

I have checked all of the macro files as suggested and they are all clean as a whistle, no visible corrupt or odd looking characters at all.

I completed a milling job yesterday and the error message did not appear at any time from start to finish of 3 hours work.

This is a definite mystery.

Hi Marco,

I have found the Macros folder in the Mach3 directory.

Question is "which file do I open to investigate for corrupt info?"

Is it spindlespeed.m1s? 

If so, can I open it with notepad so that I can edit it?

Kind Regards

Unfortunately no matter what I do I still get this error message intermittently. 

It generally appears first thing when I begin work with a new g code file (not always though). 

The only work around  that has any success is to shut down Mach3, reboot the computer, then reload Mach3.  Works most of the time (but not always). 

It occurs on both my laptop which I use to generate code in the comfort of my office when I simulate my code and on the desktop machine that I use to run my mill. 

The strange thing is that once I have made the devil of a thing go away, it remains satisfactory for the rest of the day.

Sometimes when it appears, I get so frustrated I give up for the day and go and do something else.  Next day with the same code that failed the day before it behaves like a meek little lamb.  Butter wouldn't melt in its mouth!!!

I am convinced that all it needs is an overnight rest.

I have R2.0.060.

What are the differences/improvements with R2.4?

Hi Brian,

I just returned from the shed where I was able to capture screen shots of the error message.

I was able to create the error by the following sequence:

1.  Load Mach3 with the profile that I posted recently.

2.  Load the G Code program attached to this post.

3.  Switch on the mill.

4.  Go to the MDI screen.

5.  Issue the MDI command "M3 S1500"

Hi Brian,

Thanks for you offer to have a look.

Here is my xml file.

Hi all,

My original workaround for this error message is not consistent. I still get the error sometimes. I can't seem to get a consistent set of circumstances that replicates the error. For example I used the machine for about 6 hours yesterday with no sign of the problem all day despite interrupted sessions requiring shutdown to attend various domestic chores.

Then today when I started the "unspecified failure" error reared it's ugly head again. I ended up turning off Mach3 and rebooting the control computer about 3 times with no luck. I then tried to issue M3 S*********x followed by M5 commands from the MDI screen with the mill turned off then turned on. Somewhere during this frustrating process it miraculously came good so I was able to continue milling.

Issuing M3 or M03 does not have any affect. Mach3 seems to be very tolerant to leading zeros in G code.

Perhaps it is related to the I/O board where the parallel port cable is connected to the machine.

With more use ( I am new to this) I have also noted that the I/O board seems to hold logic states for a while (say 3 - 5 minutes) when the machine is turned off. One of the symptoms is that the E Stop remains active for 3 - 5 minutes immediately after I switch off the mill. This smacks of a lack of pulldown resistors on the I/O board parallel port. If I disconnect the control cable the E Stop signal disappears, thus proving that the rogue logic signal is definitely coming from the mill.

It would be great to get to the bottom of this problem. I have been able to solve many teething problems by using this and the Syil forums.

I am in the process of machining 50 lids for a Mixer module for a Radar used in the mining industry manufactured here in Brisbane Australia. I am at Op 6 of 8 operations and the machine is working great. I took some videos tonight and will post some vision when I can work out how to compress video.



Problem now fixed!!! Thanks Brian.

The X and Y stepper motor velocity settings were 2100 instead of 1450.  I have now set these settings to 1450mm/min (according to the Syil manual for my machine the maximum is 1495mm/min if pulses from the controlling computer is 25000). 

The above settings have totally fixed the problem and also cured another problem.  That is, the movement in x and y was erratic, jerky and hesitant until the velocity was reset to 1450mm/min.

Kind Regards

Thanks Brian,

I'll have a play with the motor settings.

Attached is the xml file that I use.



Hi All,

I am having problems with Mach3 not completing the movement to the last x, y, z position requested in some G codes that I have written.  This occurs in both simulation and on my milling machine. 

It appears that if a requested Z position is reached before  a requested X position, Mach3 stops.  When the code is run for the next part, Mach3 "remembers" that it did not reach the requested X destination and completes the move that it should have done previously.  If a requested X position is reached before a requested Z position, all appears to be OK.

Below is an example of my faulty code:

(This routine spot drills 8 holes)
(CJH 26Jun07)

G00 G17 G21 G40 G49 G50 G64 G80 G90 G94
M6 T1 (TOOL Ø5 Spot Drill)
M3 S2500
G00 X8 Y14.2 Z5

(Spot Drill Routine)
N1G81 X8. Y14.2 Z-2.1 R3 F50 G99
N2 X27.5
N3 X47.5
N4 X57.5
N5 X87.5
N6 X97.5
N7 X117.5
N8 X137.

M9 M5
G00 X0 Y0 Z50
M30 (End and rewind)

It is the line "G00 X0 Y0 Z50" that X0 is never reached despite the fact that the following M30 command is reached and operates correctly.  The X position reached is always approx 29mm.

Am I missing something?
