The magnet interferes with the buttons. Causes the cnc moves to be intermittent. Once I remove it from the magnet it works fine. I guess it is just an expensive holder. I guess I could 3d print one that does not interfere.

 

Thank you for the help. I have it setup as pictured in the image on openbuilds. I am using the magnet as recommended by openbilds purchased from Amazon. I am assuming it is interference from somthing on the cnc maybe the stepper motors not sure. If I hold it in my hand about a foot away from the machine it works fine. If I set it down on the bed of my cnc I get the same intermittent issues. Somthing is being transmitted from the machine...not sure what electrical component on the cnc is causing it. This cnc is 100% all parts from openbuild parts and electronics.

 

Thank you. I will send a picture this evening as I am not where my cnc is. Also I have no dust hose and any other items that I have on the cnc. It is a pretty clean and bare system for now. You can see my machine as part of my build on my profile page if you can see them. But I will send a picture as soon as I can.

The only difference fom these pictures is that I have added the black box and limit switches from openbuilds. But all else is the same.

It has a router and it is off when this happens. Have not tried it with it on.

One thing I am going to try is insulate the bracket for the mount to the cnc with a nylon washer to see If I can break the connection if there is one.

 

All of the aluminum parts are securely connected with screws so everything is grounded together but I do not have the cnc machine machine grounded to anything. The bed is screwed to the system. The system is setting on a piece of .75 plywood base that set on a steel rolling table. None of the cnc machine touches the steel rolling table.

 

Yes it is. I wanted a bed I could clamp down any part in any place. It cost more but I get a ton of flexibility.

 

How is the bed screwed down? T-nuts typically don't break through anodization- don't assume one part of your machine is electrically connected to another part through standard screw methods. Typically the best way of ensuring electrical compliance is tapping into the end holes of the extrusion and connecting them together with braided copper ground cable. As it is, it's possible that your bed is acting as an antenna to something else in the area.

 

Here is an update. I either have a second bad interface controller or the magnet mount is not the correct thing to use as a holder. I moved the magnetic mount completely off the cnc and onto some wood off the machine. As soon as I place the unit on the magnetic mount it goes intermittent. As soon as I take it off even move it about an inch away from the magnet mount it works fine. My thinking at this point is the mount is not going to be very usefully to me. I think the interface needs to be upgraded so that it won't receive all of the interference that it does. One thing interesting is I have a basement support pole in my base ment. It is about a 2 feet away. If I use the interface in my hand and I touch the support pole with my other hand the unit goes intermittent. It is a little unnerving that the interface controller is so effected by so much interference. I think this need to be re addressed in a future design.
