Is it a 3d machined part.? You might want to start a thread on vectrics forum if you are only having issues making parts with aspire. Have you machined similar parts with Mastercam with out issues?
    Ditto, we had over 20 pages posted on the Vectrics Forum a few weeks ago and it ended up being mostly user error. Just about exactly the same thing as here. User did not understand basic CNC flow pattern or G Code and we spent a lot of time on his issue.

    I’m pretty versed in G code and cnc speak.
    Not sure why I posted it to the laser site.
    I’ve written and corrected codes before while working in Mastercam X5.
    But this is just odd.
    I went back and ran programs done in Mastercam and no problem.
    So this is just weird.
    It’s s 22” diameter dish in MDF.
    It’s only about .25” deep in the center, and as I said I’ll get 1/5 or do through it then it’ll drop the Z then everything is off.
    The PRZ is no where near it’s original position.
    With a .5” ball nose bit, it takes so long just getting to that point. I don’t really want to slow it down. But I might run it again and try to find the exact line of code it freaks out on.
    Thanks for commenting.

    I’m going to check the parameters in Vetric and see what it is.
    But do you thinkMDF has any real effect on the 1/2” ball nose?
    It basically pulverized the material.

    BTW I did look for those posts.
    I think I found them. But what I do look out was fine tuning the machine in Mach 3
    Calibrating the 3 Axis’s

    When mine did it on one design and worked on all the other I searched for days and did air cuts and it still did it. after a week of searching I discovered that the Z axis had sawdust on the bottom of the rails and had packed in hard enough to stop the axis.and the z would position thinking it was higher than it really was when it retracted. oh yeah I made a few holes in the spoil board and projects. now I watch that area carefully.

    Hi Rob - Does Vectrix have a toolpath simulation? If you can simulate the toolpath and its not in there then its mechanical. Peter

    Correct. If it's not in the Aspire preview, then it's most likely not a problem with the code.
    And if the Z axis has lost position, the g-code can't cause that to happen.

    These are some great reply’s.
    I’m better to navigate on Mastercam where I can review the G Code to see if there are weird moves. Not sure if I can review the codes.

    So, I’ll clean up the terminals and inspect the wiring and the ball screw.

    I do agree that it’s not a software issue, but can it be an operator issue?
    I mean, I’m only cutting MDF with no sudden moves.
    It’s a simple bowl, 22” Diameter and not quite .25 deep.
    Thanks for your help.

    Yes it does, but not sure if you can view the G Code

    Ho Rob - Don't have to see the G code just play the simulation and see if it drops. That's what simulations are for... Peter

    It’s not the greatest video. But I’m sure there’s nothing wrong in the simulation.
    It’s gotta be mechanical.
    I’ll try the clean up tomorrow

    Just open the cnc file with notepad ++ or visual studio. Just curious you said you use master cam, how do you not know how to use aspire? Master Cam is thousands of dollars and I would assume that if you have a seat you would be a proficient designer and know how to create toolpaths, Aspire is very simple to use compared to master cam. Years ago I had a rep trying to sell us a seat and it was around 15k so we decided to just pay a design firm to do are design work and prototyping since the parts were being made overseas anyway. Can you post some pictures of the tool paths you are using for the design, is it a 3d tool path? Why don't you just use master cam to draw the part and see if you have the same issue? That way you can eliminate any possibility that it's the Gcode.

    Are you running dust collection while it was cutting? If so is it grounded? I had static electricity make mine do that once.
