I wanted to jump back in and update the cause and solution.

Everything seemed to point to the breaker but the chattering came back. It turns out that it was caused by the G61 code that I added to...

After much testing I think I was able to narrow the problem down to a bad 30A breaker in my shop sub-panel. I am now back up and running strong.

Thanks for jumping in and the suggestions guys!...

Hey guys,
I have been running my CNC now for quite some time with no issues at all. The other day I started it up and when Homing it I noticed some high pitch whining sound coming from one/some of...

That makes sense guys! Thanks for the info.

Thanks Rod.

Yes that is exactly how I have mine set. So how can so many others be running fine with something like 200 or 400? I even saw one that was 80. It makes me think the number is...

Thanks guys for the info. I appreciate it.

As with a lot of the info I have found on building my CNC there is conflicting info. But it gives me a starting point and I now understand how to adjust...

So I have finally got my CNC built. I have it communicating with LinuxCNC. I am in the process of setting up the ini/hal files and am needing some help with figuring out the correct microstep/current...

I have been struggling for days to figure out how to set the initial Home for all my axes in LinuxCNC. My CNC experience comes from Arduino Mega 2560 + v1.2b Shield where I could move all axes to...

Now that I read through my post above I think I am confused on how the circuit(s) would run through the E-stop switch. Hmmm

I am interested in this design for my E-stop Safety Circuit. I am new to SSR's. Can someone help determine which SSR I would need for my system and help explain how it would be hooked up?

NOTE: I...

I apologize for my troubles understanding these stops/switches. I do tons of research only to walk away completely confused because I either read contradicting info or I completely misunderstand what...

I understand now that E-stops are for low voltage circuits and the disconnect is for the high voltage circuit. I see there are magnetic switches that help protect from power outages that once tripped...

OK so I misunderstood what you meant when you said "If you are using a Cabinet of some kind, you would first have a disconnect (Safety Switch) at the Power entrance to the Cabinet, the Power supply...

So I wanted to run my E-stop/breaker diagram by you guys before I get too far into it. This is just the power coming in to the PS's. The E-stop would be mounted to the cabinet. I will install more...

I will keep this in mind. Thanks

Thanks. Just want to be sure. Don't want to burn it to the ground.

Peter,
I am in the process of creating my electrical diagram and I have a question. You say that drivers should not be daisy chained but instead should be connected to the PS individually. As I am...

While I am waiting for my cabinet to arrive, I am trying to determine all the additional parts and components that I will need. As mentioned above, I will most likely be adding breakers, E-stops, GND...

The smaller PS says "Protections: Short-circuit, Overload, Overvoltage" but that is all I could find.

The large PS says "Protection: OCP OVP SCP OPP" and "Overload protection 105-150% rated...

Here is what I have come up with for breakers. Since I am new to a lot of this I would like to make sure I order the correct components.

I have two PS's.

60V/1200W
Input: 110V/8A
I came up...

And just to be perfectly clear for myself and others that are here learning, this means "INPUT CURRENT (of the PS)" X 125%? Not the "OUTPUT CURRENT"?

If this is correct, then my input current of...

Good info. I will keep that in mind and check my wires/cables.

I had to check because you stated "PLUS" in your statement. I knew it didn't sound right. Thanks!

So if my PS is 20 amps, does that man I need a breaker that is 45 amps?

Thanks

Don't tell me that. LOL. My original size was 20"x12"x9". Since I am not running a spindle/inverter I figured this would be plenty of room. Fingers crossed!

Thanks for the copy. I will be reading through it as I design my cabinet.

Thanks for that info. I am in the process of drawing up a electrical panel diagram so I can see what I need and where it goes so that it all makes sense in my head. I will try to add the breakers and...

I tried finding the NFPA79 but I guess it is not available for download unless you buy it. I would like to lay out my enclosure properly if I can. To be honest I feel like I am getting more confused...

Sorry Peter. Not sure how to get it to show. I attached it and could see it when I previewed the post but apparently it does not work that way. I also tried but that didn't work either.

I decided to start with 18g 4 conductor (non-twisted/unshielded) cable for my motor cables. If I have issues with noise I will go with twisted pairs. But since I am not running a spindle I figured I...
