Dyna Myte 4400M with Meldas M3 Control. I think the battery is dead

Hello I am new to the cnc world but I got a Dyna 4400 M with the Meldas M3 controls. It wont do anything when the power is on. I believe the battery might be dead. The previous owners barely used it. They also told me the battery has died before. I could use some help on restoring the unit to working order. It does have a tool changer so I will need the program for that and the parameters to set the cnc up. I saw a previous post about the dip switches so I will try it first but wanted to get the ball rolling for some assistance. I will also be setting it up to drip feed programs due to my cam program is 3000K.

Thanks,
Patrick

Hey Patrick,

I' dont know the answer to your question but i have search answers about DM 4400M, can you help me.
Is it servo motors on your mill?
can you have dropp fee?
what is the dimension of the machine and weight?

Have you replaced the battery? I am guessing you are referring to the battery on the motherboard.

Cblad, do you mean " can you drip feed the mill"?

Patrick,

Hope you got your machine running. If not, Sorry I'm so late in getting to your post.

Attached are files to get you up and running if it IS a dead battery situation.

Files include: Step-by-step Instructions on what to do.

Parameters.

Tool Change file.

I have had to do this many times.

email me if you need more help

Good Luck

Hello Bill, thanks for the files from your post they worked like a champ, I know I'm replying to a 3 1/2 year old post, but I want to thank you for the files. My dead Battery problem was a simple fix thanks to your help. I just purchased a DynaMyte 4400M with a dead battery and was able to go from a blank screen to working screen, Now I have a few errors (E7 error) I need to learn how to clear, but getting closer to having a working machine.

thanks for the Post,

Jim

Hi Jim,
I'm glad that the files helped you out. Where are you located? I'm 40 miles west of Chicago. When you get yours working, feel free to stop by and get running. It's been sitting dead for about 4 years now.

Hello Bill, I'm in Jacksonville, FL. Sorry hear your is DOA, I just picked mine up last month, Do you Know how to Clear the warnings on the unit? I can not find anything on how to do it? I even have the manuals and I have actually read them, they tell you what they are, "NC Emergency stop" alarms, but I can not find how to correct them or clear them. any ideas? or should I try Mitsubishi Support?

Thanks,

JIm

I'm helping someone out with a DM4500 I think.

Seems to be the same control and very similar machine all together.

He had the same issue with the battery, but thankfully he had backups and I was able to get it up and running except for the tool changer.

Trying to call a tool, the carousel will turn forever. I read about this issue in the operation manual with the note to call Dyna. I haven't called them yet, but was hoping someone else here has run into this and has the fix.

PNaedele,
I'd call quickly... Dyna itself is kind of kaput, I believe. They have no presence in San Jose at all, and I don't think they have any manufacturing elsewhere either. Although their website is 'up', I think it is being serviced by an ex-employee that has branched out on his own. The big question, however, is how long he will be providing that service. It could be a long time or it could be next week. I believe he has Dyna's old phone number, though, so you can try calling him. I'm told he is quite nice and very helpful. :)

bkobernus:
Thank you for posting that writeup and information "packet". I am hoping to pickup a 4400M in the next few weeks. One thing I noted on it, however, was that its switch panel looks different than others. I've got a photo somewhere that I can send, but between that and the fact that the machine has a 4th axis, it makes me wonder if the logic ladder might not be different (which I assume is the M3 parameter list). This, then, brings me to a different question entirely....

Do you know how to *download* all of the parameters currently in a machine so that you can back them up? Whoever generated that M3 parameter file probably has that information. I think the best solution for me would be to download the file for safekeeping just to be sure there aren't different flavors of M3 based DM4400M mills out there.

It's been so long, that I would have to review my notes, and then actually sit at the machine and figure it out. Other wise you just have to go through all of the parameters manually.
I have all the manuals, just have to look it up. <<<< Not an easy task. Have you ever tried to read English written by Japanese? It doesn't make too much sense.

Your control looks well used.

Is the magnetic switch working on the carousel? I would check mechanical before blaming software.

LOL... yeah, the control does look "well used", indeed. By the same token, it seems like all of the Dyna pictures out there, save a few, all have broken key caps. I'm not sure why. Maybe it is exposure to fluid or something? Anyhow, the machine all works fine and I'll post more about it once I have it in my possession.

I managed to get the manuals yesterday, but I didn't see anything in there about downloading (or uploading) the code that is custom to the machine. I've left that statement a little vague because I've learned that in addition to the PLC (or which I think there are two areas?), the macros are also custom and need to be backed up. I must admit that I'm a little paranoid with this one. And it doesn't help that the CRT on this machine seems to be having some issues. The sync is off and it rolls until warmed up; but even then, the vertical sync is placing the "top" of the image in the middle of the screen, which really makes navigating tough. If you, Bill, decide you want to have a Sunday afternoon challenge, feel free to read through the Japanese English (I know what you mean... but at least it is better than Chinglish, which is often completely nonsensical)! I'd love to know the steps in drop dead "do X, press Y, wait, do Z" format

I have one other problem. Before I had access to the manuals, I was given the chance to play around with the machine. That is really really nerve wracking when you don't know a control! Anyhow, I somehow managed to advance the Y axis to the limit (table farthese from the operator). It was with the MPG at low speed so definitely no damage there; in fact, a non-event really. But the weird thing is that I can't advance the table off the limit now! In fact, it will only advance in the negative direction (into the column) where it will, of course, run out of travel (hard stop). The control detects the following error, returns to the old position (positive Y) and shuts down with an error.... For full disclosure, even when 'Ready', the error LED is on an there is an M01 error (but the aforementioned screen issues, along with my naivety on the control prevent me from seeing much more on that).... So, the question is... How do I get it off this limit? I think I may have gotten into this boat with the ABS MAN switch... Not sure there though. Anyhow, I'm assuming there is an easy way to resolve the problem. Physically I might be able to rotate the leadscrew (not sure), or I could probably remove the limit switch temporarily. Both those are pretty. This is not an unusual situation, so I'm assuming there is an easy solution.

Shoot... I kind of hijacked this thread. I have a few open now while I research this machine. I was simply replying to Bill's comments and didn't realize I might stomp on some other topic.
