motor fault at same spot

[brian]

Thanks for the info
I just ran the file in aspire this time and it stop in the same place(does not seem intermittent)
I adjusted the bearing on the Z axis to make sure it was running smooth.
What gets me about this is it stops in the same place (M3,1085000,16828643,-0.486667)every time and it the second pass on the same vector
I will check the wiring tomorrow

A motor fault is indicating an axis cannot move to the instructed location. The file is not likely to be the problem. You say it is in the same line in the file, is it also in the same position on the table? I would suspect the Z being the issue, as you stated the Z pops up when you get the message. What was the Z doing about 3 seconds before you got the fault. The reason I ask is the Alpha motor will try to self correct and if it cannot within three seconds it will fault. What is the length of cutter you are using? Can the Z move down to the location is being instructed to go?

I hope this is of some help. If you are still having this issue please give us a call.

Another thing you could possibly try is to remove your router bit and run the file doing an air cut to see if you hear or see anything perculiar that you might not be able to hear if the router was running and cutting.

Also is it in the "exact" same place when it craps out or "in the same general area"? And is there anything special about the area where it defaults, like the top end of a Z move?

The location
M3,1085000,16828643,-0.486667
is exactly the same(line 40)
befor I redid the toolpath it was line 60 it stopped on
As you can see from above the Z is only -.486667 down from the top of the material which is .73 so The Z axis is know where near its limit.
I posted the file above (previous Post)
I will try out the suggestions thanks

Brian, do you see the same thing happen if you run the file at various locations on the table? Either move to a different spot and run it offset 2d or issue a Z2 at another location and run as normal.

Is it just me but M3 is move 3 to M3,1085000,16828643,-0.486667

There are no decimal points so moving X to 1085000 and Y to 16828643 would be way off the table. This looks like the problem to me.

I can't answer why that code was generated but it seems to have misplaced a decimal point IMHO.

Never mind I see in the actual code it does have the decimal point.

After talking to Ryan from shopbot
I did a test run without the material and it ran fine
Same test with material in place,it failed again.
Something that didn't occur to me was to remove the pressure foot I was using.
After removing the PF I ran the file and it worked.
I'm still baffled as to what caused the fault.
The pressure foot was freshly lubed and the material was baltic birch.
The only thing I can think of was the pressure foot was set wrong(it had bottomed out)
If that was the case I feel a little stupid.

Thanks for all the help
