Good afternoon.

After some time, I have a problem. The printer stops printing error "SD read error".

That log printing from a memory card from Pronterface program.

UPD. I tried different memory card. The problem is repeated.

Repetier

M106 is ok, you compiled without fan support but slicer uses it.

Does the error always happen on the same position on both cards? Or is it a random position so it is more a real reading problem? In that case make sure the cable is shielded and does not come near powered lines like heaters/steppers. Here crosstalk can easily influence reading.

Its hardware problem. I'm change "smart controller" and all work good. Pls close topic.

Hi, I have  the same error prompt  on everytime I try to print by SD card, o every gcode file. 

I don't understand the ZMan answer.

Can you help me?
