M2 frequent E084 Y2current error

Hello Carmine,

I actually have/had this same exact error. I was getting this error almost every time i started up the machine. I just got it "somewhat" fixed today. After spending some time on the phone with a very helpful coldesi tech, who ran me through the different issues that could cause this. We focused on the "plunger" for a while, but something was telling me this just was not it. We ended up ending the day yesterday with him having me remove the print head to check the ribbon cables. I did. No burn marks, cables looked great. What I did find is that the print head was loose, they are not secured very well in these M-2's. The print head was not sitting correctly and making contact with something that seemed to be shorting out the printer, I even got a spark in my machine at one point. giving me that exact error. We made sure we secured the head and tried to make sure it was sitting exactly where it should be.

I say my problem was "somewhat" fixed because I have seen that error again one time today, but not near as many as before. (was giving the error 9 out of 10 times) now Gives it about 1 out of every 10 startups.

Now, I have also had the same issues with the print bed, giving me a 074 error when the bed is not loaded and I try to send over a graphic for print. I have circumvented this by always making sure the table is in the loaded position with the green light on.

I believe this is a larger electrical issue in the machine, I am no electrical engineer, but something just seems off. The tech said he agree'd with me about the electrical diagnosis, but who knows, I could be way off.

Please let me know if this helps, I am still trying to nail it down so I have no more errors at all!

The machine has reverted back to not functional. It 084 error's every chance it can. The machine started to error out now during printing a quality dark garment. I got away with a white, but it seems to not like the darks. The machine will give me that error whenever I am sending information to it on the computer. For example: I send a file to be printed on a dark shirt. The shirt starts printing, if the file is still sending to the printer while it starts printing it errors out and freezes the file transfer on the PC. I have changed computers and even gone as far as to purchase a new PC. This "084 Y2current" error seems to pop up in all random places. During startup, while doing a cleaning, and now while printing. The printer will also freeze up if I try to send a file over before the printer is in the "loaded position" I was trying to have the file sent in full before I began printing, but the printer would just freeze and not react one I sent it a file over and tried to load the board.



Any feedback would be appreciated. Thanks

I'm curious as to the solution in case I come upon this in the future. Was there any solution?

I don't have a solid solution, but here is what happened to get me running again:

ColDesi sent me a picture of this locking mechanism and asked that I ensure there is minimal play in it (should not tilt; some rotation is fine).

The overcurrent error is a broad error not specific to any one component. In my case, it is being triggered because the carriage motor is trying to move the carriage when it is still locked in place, and the motor draws too much current when trying to overcome the load. The source of trouble is that the carriage locking mechanism is not completely releasing the carriage.

I have not had the issue occur in a week since I fidgeted around with the locking mechanism. To be honest, I didn't do more than poke at it, rock it around, press it up and down and check the tilt. It may have been sitting in a position that caused it to not move freely, and manually playing with it seemed to have corrected that. I will let you all know if it comes back again.

Thanks,
Carmine

I was able to fix my error, which was the same exact error. The machine has not produced the error again.

My fix had to do with the ribbon cables coming from the black box that went down to the head. Those cables fold over around the middle of the cable. Where they folded, they were rubbing up against the metal piece that holds the dampers in place. The constant rubbing ended up wearing down the cable to the point where it was making electrical contact with the metal piece. Producing the E084 Y2Current error. that would happened randomly. Now that I understand what it was, I see that it was not random, but when the cable would hit the metal.

My quick fix was some electrical tape around the ribbon cable and on the corner of the metal damper holder where it was making contact. A long term fix would be a new cable and something in-between the cable and the metal piece. A piece of foam or something similar.

From what I see, it was a flaw that will eventually happen to any machine that has that ribbon cable touching the metal damper holder. It is inevitable, unless you take pro-active action to stop the two from contacting each other.

Directemb,


Hi in general I think it stops in the center of the printer but I can say for certain its the same spot every time.

The printer won't turn on at all. We checked the fuses and they are all good.
