UM 2 ... first print..."sd card reading and then frozen"

[pavel 0]

Hi all,

Today I got 2 UM, over month waiting. Great!!!

 

But I was quickly disappointed.

 

When I wanted to make a first printing UM after calibration, the system display the message "reading SD cards ..." and nothing.

I tried use another sd card, reinstall the firmware, save a new print file through Cura. I still get only message 'reading sd card" and nothing more.

 

Does anyone have the same problem?

 

Best

Most of the problems with the SD card are fixed if you move the ribbon cables just a little bit. Remove the larger cover on the bottom of the UM2. There are 2 gray flat cables in the corner. Try moving them away from each other maybe and try leaving the cover off. See if that helps.

So, I tried to move with both cables, pull out from connector and get back agin. Still same problem...only message "Reading card". Oppps.

I do not like fold of the cable on the input exp1...look at pic.

It is right that one of the cables (white, blue) is freely?

That's normal. It is the same way on my machine. I think that is for if Ultimaker ever sells a "dual nozzle" upgrade. I think it will go to "temp2".

I see that your SD card issues have been resolved in another thread and that Sander is sending you a new cable.

To be on the safe side I put the cable professionally measure and is fine:-(.

Bug is elsewhere.

I believe the problem with the ribbon cables is usually "cross talk" where signals from one cable pass to the other as radio waves. So a meter won't show the problem. Try keeping the cables at least 10mm apart. Or just wait for Sander's new cable.

I have the same problem. Screen says reading SD card. Nothing happens and it appears to be frozen. I need help.
