    Z plunges for no reason!

    I’m trying to make a sanding dish that is 22” in diameter and maybe .25 deep
    I’m using a KL1212 router and Mach 3 along with Vetric Aspire.
    I used all the default parameters when I chose a .5” ball nose for the rough cut.
    About 1/5th the way into the cut, the Z plunges and throws everything off kilter.
    Any thoughts?

    Which controller you have?

    Hello Rob - Machines do not do anything for no reason. You will have to work through the mechanics of the machine to check everything is OK and you will have to check the program is OK. No simple answer... Peter

    Re: Z plunges for no reason!

    Where does the model for the project come from?I would be more concerned about a discontinuity in the surface of the stl file than the machine in the first instance.I only have a little experience using Vectric software for 3D projects and that was Vcarve rather than Aspire so I might be missing something on that side,but given that the machine has worked previously,why would it start to misbehave now?Did nothing show up on the animation of the cut?I would run the simulation again at the highest resolution and look closely at the problem zone to see if a sudden plunge is apparent before attempting to diagnose a machine problem that might not exist.

    Run the simulation and run it at slow speed, if its not showing in that or the final results its a mechanical/electrical issue with your machine.

    I created the dish in Vetric Aspire.
    I set the parameters and used default settings for the .5 ball mill.
    I’m going to add a picture shortly.

    BTW, nothing showed up in the simulation. It was a clean run.
    The fact that it happened twice worries me.
    Check out the cut. There’s a dot that indicates where it plunged and a deep cut along the x axis after the PRZ was rearranged

    This is a second try showing a similar result.
    There are other screw holes thT don’t have anything to do with it, but the Z plunge us there along with that wacky X axis run

    Once again you have machine or electrical issues.

    Electrical noise would be the culprit No1, IMHO.

    Re: Z plunges for no reason!

    So, to ground the dust collector hose.
    I need to run a copper line inside the ductwork all the way back to the collector then back to a grounding rod?
    And noise
    I gave fluorescent lights and LED Florescent lights.
    Then there are fans and a window unit AC
    The computer and the machine are not connected to any Wi-Fi.
    Am I thinking it through correctly?

    You ground to ths same grounding lug the rest of the control system is grounded too. Are you in US or where? Only in China or other undeveloped countries without a grounded electrical supply system do you need a ground rod. In US or others the 3 wire system using a ground connected at the main service panel is where it needs to be grounded to.

    Yes others have ran a bare copper wire inside the dust collection hose and fittings and back to the machine ground to drain off static electricity.
    Everything needs to be grounded in your shop.

    That’s clear good help.
    I’ll get in that.
