I never use the Ref All Home, I set the table where I want it and the use the ZeroX,Y,Z buttons. Did yuo see anything weird in my M6 macros?

What I meant is the DROs read what the G Code is, then when the machine starts to move the DROs change, but the DROs do not try to catch up like if you had feedback. They are reading where the tool bit is. There is no consisteny with what is happening. Sometime using the ATZ feature causes a problem, sometimes it doesn't. Sometimes there is a problem after the second tool change, sometimes it is after the fifth tool change. I watch very carefully to try and remember what was happening at the time there is a problem. But there is no consistency so one time it is this way and another time it may be a different scenario, but there is some overlap or similiarities. 




I am getting confused, one minute the DROs are the same the next they are moving.
Really I think you have to be very methodical in noting down what you see and describing it when things go wrong. What you need to note is where the DRO and Toolpath say the axis is and whether or not it is actually there. Forget the return to zero as all that is telling you is you have lost position, we need to try and work out why you have lost position.

As for the pulsing too fast, was Mach running at the time?

This is why I am obsessed with the origin changing. Now the DROs do not change. It seems like some how the origin location is changed in memory or wherever Mach keeps it. Now this doesn't happen every single time I run a part. On Tuesday I ran for over 10 hours with no troubles, this was two parts, each about 4.5 hours each. I started a new part and everything was going fine until I realized that I needed to make a programming change. I stopped Mach, pushed Go To Zero, Closed the G Code. I then made my programming change and loaded my revised G Code. I pushed Cycle Start and the program was running fine. Then I heard the cutter getting bogged down and it then took the huge pass that you can see in my photos that I posted. There was no tool change when this happed. I have since removed the ATZ macros and tryed to run the same part. The first time I ran the part the drilling cycle ran for about four holes, on the fifth hole the drill bit was drug acrossed the work piece instead of being .25 safe Z height, I stopped the program run. I tried a second piece after resetting the DROs and Zeroing the Z axis. This time the drill bit plunged quickly into the work piece and I saw the DRO change and it was about .625 below what the original Z height.

I haven't run anything since, I did try to run my Driver Test and I always get Puling Too Fast. I have run the Driver Test with Mach running and without, always the same results.

Let's try and start over.



I have removed the ATZ macro and all related items.

This is the same download of Mach that I have installed on three computers.

The computer I am using now is a fresh rebuilt PC, there is no internet connections or other programs running other XP and Mach. This is also a fresh install of Mach on this PC.

There is nothing else running in the garage or house electrically that I know of that is different from a week, month or six months ago.



Now here is what is happening:

Usually I experience a problem (about 90% of the time) after a tool change. The DROs will read whatever the related G Code states. I will change the tool and either manually or using the ATZ feature zero the Z axis. The Z DRO will read 1.000 if I use the ATZ feature. I then push Cycle Start and I can tell instantly that the toolpath is headed in the wrong direction. I have never looked to see if the display screen shows the toolpath in the wrong location. The DROs will read where the tool is sitting at the time of that I stopped the program run. What I do know is that the 0,0 is NOT wher it should be. This is where the problem is (or so I think). If I understand this correctly every machine move is related to an origin, it doesn't have to be 0,0, but there has to be a common known location to base every move from.

1 question,  When this last happened and MACH wondered off, did you see the wandering off in the toolpath display as well?


I did not notice this.



AND did the dros show that it had wondered off the programed toolpath?


No, they showed exactly what the G Code stated at the time of the tool change



Have you tired to reload a known good backup of the XML?


No I haven't




IF you do not have one build a brand new XML from scratch using all the setup info that you have in your old one.

IF that does not work then do a completed reload of mach.  BUT FIRST document precisely how it happens NEXT TIME it does it

IT is important when testing that you do not jump around doing a lot of different things at the same time. ONLY a methodical test approach will find your problem. NOTES as Hood said LOTS of noted describing each step you take. AND do them them one step at a time.


I typically change one thing at a time

You explanation is somewhat all over the place as Hood said.  Settle down and we can get to the bottom of the problem.


I think what the problem is I am not saying what I exactly mean. Or this is a miscommunication in the question vs. the answer.

General Mach Discussion / Pulsing Too Fast

I ran the driver test and I get the message Pulsing Too Fast. I looked in the documentation and did a search and I could not find anything to tell me how or why I am getting this message. I'm running a kernel speed of 25kHz. I am also running an onboard PP port, should I have an external PP card?

Disabling the ATZ function and macros did nothing.

Yes the DROs were showing the movement, but they continued "counting" from where the were X  -2.9884, Y  -1.1250.

I tried to do a driver test and I am told that it is Pulsing Too Fast.
