That looks a good deal, 75% off the purchase price plus free upgrade to V6.0 when it is released.  I like DP

General Mach Discussion / Re: Mach3 loses Y axis location during code

Chad,

It is not so much the number of lines of code as much as it is the content of the code and how the PC handles the data.

Your compiled GCode has such redundancy that I would you suggest that you check with Vectric that you are in fact running the full licensed version of their software and not the demo.

Hi Hood,

I just tried it with the toolpath view turned off but no difference it crashes at, more or less, exactly the same place.

General Mach Discussion / Re: Latest version of Mach3

« on: May 04, 2011, 03:31:34 AM »

Hi John,

This sounds like you have a problem with your setup rather than the version of Mach3 that you are using.
It is a tedious job but you need to check everything.
Have you changed anything recently such as rewiring or using extension cables etc etc. ?

Chad,

This appears to be a Mach / PC related problem in so far as the length of the GCode is concerned. I have now run your code twice and had errors on both occasions.
In my case the X axis Scale DRO is changing to -1.0000 of it’s own accord and the machine takes off to the other side of the table.

I have another PC which has the maximum RAM and I will try that just to see if it is a memory paging issue but I have examined the GCode itself and can find nothing that would cause this fault so I can only conclude that it is the size / length of the GCode which is upsetting either Mach3 or the PC.

Reworking your model to produce a number of smaller programs which could be executed concurrently may provide a practical solution and for now, be the best way to proceed.

Could anyone else perhaps try this CGode and see if they have problems also ?

Chad,

I am using version R3.043.022 and I just had a problem with X position when running your code.
May be me or it may be the code or it may just be the length / size of the code, in any event it deserves further investigation. I will try it again later and see just what is going on.

It is obviously not just a matter of replacing the cables, as you have just found.
Do you understand what I said in my earlier post about wiring loops and have you checked for and eliminated them ?
Have you tried bypassing the breakout board as suggested by Chris ?
Have you tried another PC to eliminate possible pp problems ?

Your earlier statement may perhaps be true "It's now left me with 2 possablities, it's either the bob or mach3". I think we all know it is not Mach3 so junk your BoB and replace it with a known good one, perhaps from CNC4PC http://www.cnc4pc.com/Store/osc/advanced_search_result.php?keywords=breakout+board&x=21&y=9
This is the direction I would take.

Just a thought but there should be two 7 Amp fuses (F1 & F2) on the main board - these relate to each RF board supply.
