Newbe Needs help-trying not to return machine!

[Alex_Cole]

I just purchased a Dyna-Mite 2400 mill. This mill has it's own control on it and really is a solid machine. The problem is it was supposed to work when I got it. I had them test it and home the machine when I sent people to pick it up. Long story short. I have had it now for 2 days and it right of the bat started to reset the control randomly. It seemed like it was shorting out. I took a look in the case and found no shorts. There was a some what sizzling sound coming from the line filters. I have no idea what a line filter is or does that is just what it says on the component that was making the sound. I talked with the salesman and we may be able to work out a deal where he helps me with the cost of the components to replace the control system with a new setup.

The problem I have is that the spindle is variable speed and seems to be linked with some wires to the contrller boards that are in the system now. I am confident that I can hookup and setup the stuff for the new stepper control system but I do not know how to deal with the spindle.

I can tell what board controls the spindle stuff but the line filters that I think are toast also run power to the spindle board.

What exactly is a: EMI FILTER
GA2A-5
5A 115/250 VAC
50/60 Hz

That is what is says on the little box. I feel this is where i am having my trouble with the spindle not coming on as the lights on the DC power supply turn on but then turn off after just a few seconds.

I put a volt meter on the wires coming through the plug and get good 115-120v but coming out of the end of this little thing it is more like 43ma.

Does anyone know where I could get a replacement(or three)

What exactly does the line filter do?

If I setup the spindle on it's own plug, meaning I run a new power line in the control box for the new driver system do I need one of those filters?

Any help would be greatly appreciated. I only have until Sat, 18th to return it. It is the only day I have available to drive the machine back the 160 miles to were we got it from.

Is there a way I can replace the stuff for the spindle and impliment a new driver for the spindle motor?

This machine is still supported by Dyna Mechtronics but I wont spend a bunch of money to open a support contract with them so I can decide if I am returning this thing or not.

Right now I am very discouraged and out of my leage when it comes to electronics issues like this.

Thanks for any help!

If it is rated at 5A it is not very large, You can get a replacement from some one who sells Corcom or similar.
Do a search for Corcom and a supplier should pop up.
These are common LC (Inductor/Capacitor) filters.
I believe DigiKey sell them.

how do I know what part to get as a replacement? What exactly is a common LC (Inductor/Capacitor) filter?

Do I just need to get any 5amp filter?



Thanks for your feedback

Is this what I need to get?

Use a power entry module/filter....go to mouser.com and look under power.

Something like this 5VB1 for eg http://rocky.digikey.com/WebLib/CII-...B%20Series.pdf

Thanks for all your help. I am still not sure what I am going to do. I hate to try to cobble this machine together being that I don't know what I am really doing. I think I might just take it back and get a taig. I'm affraid I won't be able to get this one working right. At least if I get a new machine I can be sure I will get somthing that is working...or at least with electronics that I can work with.

Filters aren't supposed to sizzle,
If you someone available with basic electronics / electrical skills, you can probably remove the filter and wire direct for testing of the rest of the circuit..Usually they are there to filter ripple or induced rf noise coming in..
If you think your power coming in is fairly clean, or you can add an additional filter [such as a filtered power bar with adequate current rating] no harm 'should' come to your electronics by temporarily bypassing the filter..
Filters of this type are pretty common in older electronics equipment such as photocopies, larger laser printers, microwaves...stuff that can be pretty handy for spare parts..
The filter should be replaced [if that's what the problem is], just to keep the internals relatively stock as far as it was when manufactured..

That would be a shame I think, getting rid of it. The Dyna's look like very stout, well made machines, although the controls are probably too old and unique to try and save. I would imagine the spindle would use some type of analog input signal as a command for the speed control. That would not be difficult to implement with Mach3 and the right I/O device, maybe something like this:

Put as much info up here as you can, take and post some pictures as well. I am sure you'l get all the help you need right here, if you keep asking and posting. It is fine to keep asking the same question, it is the best way to get the most feedback.

You can bypass that EMI filter for a test of your spindle. It will be fine just to turn it on and verify that it works for a short time under no load. Replacing it should be easy also, just make sure the current rating is higher than the one your replacing and try to get the same type connecting posts.

Try this place out for EMI Filters:

Good luck!

The filter has 3 wires coming into it and two going out. What do I need to do with the 3rd wire. I have white black and green going in and only two going to the board I think is the spindle driver and the other filter goes to the two power supplies.

Any thoughts?

The 3 wires going in are live (black),common (white) and ground (green). The two out are load & common. The green should be connected to your system ground plate or incomming system ground.
Pictures would help in identifying what you have.

Here are pictures of the inside of the controller. Some are not rotated but you should be able to see the stuff.


Pic 1 is of the filters

pic 2 is of one of the power supplies that is fed from one of the filters.

Pic 3 is an over view that shows the filters and the two powersupplies. I believe these are both for the driver and control system.

Pic 4 is of the board that is to the right of the filters. This I believe is the spindles variable speed driver board. it also does not work.
