DEK 03! CAN Node Rising Table Error | 13 January, 2022

Hello, and thank you in advance for your help.

I have just received a used DEK 03i and I am having a problem that I don't know exactly how to troubleshoot.

The DEK will power up correctly and everything will initialize.

When I try to set up a new product I am at the step of loading a board to verify the fiducials. Everytime I do that the rising table moves to the board transfer height and I get the following error.

Controller Area Network (CAN) Node Error CAN Node Rising Table Motor

The only way to recover this is to power cycle the machine.

I am able to move the rising table in diagnostics mode to the board transfer height, and camera height, However when I move it to print height in diagnostics I get a [ SYSTEM ERROR ] and the DEK must be power cycled.

I am able to load a board and stencil in Diagnostics mode and verify the fiducials with out issue.

I looked at every single connector on this DEK to be sure there was nothing loose.

I pulled all the cards and re-seated them too.

No change.

One thing I was wanting to find is if there is a persistent error log somewhere. If I could determine if this error was happening before the DEK was shipped that might send me on a different trouble shooting path then if it's only started happening after shipping.

Hmm, I don't seem to be able to post an image here.

Thank you for all your help

Hello Jeff, error is telling you exactly what it is - communication problem. CAN interface is interrupted somewhere. Motors are constantly sharing position and commands with computer over CAN interface. To get this message means somewhere this circuit gets disconnected.In your case it seems it might be related to table movement. Follow the purple cable - DEK usually use this one for CAN interface.Check all connections on this cable. If not loose connection, it might be a cable being broken somewhere.

Thank you very much I will look for something moving, loose or getting pinched when the table moves. -- Update -- checked every single connector, all the purple cables/connectors too. Everything it tight and not getting hung up.

Checked all the voltages and the are all at or slightly higher then they need to be. 5.0v is 5.2v 48v supply is 49v, 5.5v supply is 5.49

I also tried to jog the table up while I manually lifted the rails to see if a rail moving was somehow causing the error, it did not cause an issue.

Which of the next move cards is it that is responsible for the table? None of them are labeled table They say Y actuator & Moving Rail front & rear squeegees fwd & rear actuators

I think maybe none of those boards are for the lift table.

I don't seem to be finding any loose connections.

I am starting to suspect perhaps the rising table driver, BGE9010C, or the Motor it's self. I just don't know how to prove one or the other.

How sensitive to pressure should the table be? While jogging the table up in diagnostics mode if I push down on the table just a little bit the DEK will fault with a [ system error ]

Chapter 7 - Machine Control of the DEK manual outlines connectivity between the rising table servo node 6 and the NextMove ES card. If you don't have the manual, just PM me. I'm not an expert in DEK repair, but the solution could be as simple as cleaning the contacts in the edge connector.

I am interested to know if you solved this problem. We are experiencing something similar. The table is the first node in the CAN chain. As I see the structure, the CAN starts from the Nextmove ES card, goes first to the table driver and continues to the other nodes. Except for the table driver all the nodes use 2 D9 connectors, one as input and the other as output. While I had the raising table error appearing from time to time, after a while I started to receive errors from other nodes and then an error message according to which the system was unable to initialize the NextmoveES card, or unable to download the software to it. I replaced the Nextmove card, the same situation. Hard to believe that 2 cards are not working, but this happens. One thing that I noticed is that according to the schematics the DEK CAN Bus is using the ground wire. I know that CAN can work with 2 wires only, but engineers recommend using the ground wherever possible. What happens is that originally, according to the schematics the machine had the two D9 connectors on the raising table motor bottom. What I see on the machine is that the network cable goes to the rear of the machine to the BGE9010C driver instead. here the cable ends with green IPC connectors, and the purple cable that continues to the next node is connected to the same screw contact. But the ground wire is interrupted, the remaining network works without ground. I am thinking of connecting a scope and see if there is any interference. Everything points towards the NextmoveES card, but I have a strange feeling that something else is wrong.

My problem was the BGE9010C. Any time there was any pressure on the rising table the error would occur.

I was not able to find a replacement BGE9010C so I opened it up and found some blown components. Replaced them and the problem was solved.

I "think" the BGE9010C is only in the 2007 and earlier models. I have a 2008 DEK 03i and it does not have a BGE9010C driver.

If your DEK does have a BGE9010C, it wouldn't hurt to open/inspect it. I would be happy to tell you what parts I replaced if you get to that point.

Thanks Jeff, Yes, I will be glad to know which parts you replaced, at least it will give me an idea where to start looking. I also have a feeling that being the first node, the BGE9010C if not working properly may distort the CAN Bus signal. I even tested once by taking out the connector with the 2 CAN wires that plugs on the bottom. That error about the system being unable to initialize the Nextmove card disappeared. I have a DEK Europa. Here is my email too: emanuel@lumilex.com
