Hi, Now I have another problem. Z-axis isn't moving while printing - it keeps printing layers on the same level. In "pronterface" software it works ok, goes up and down when tested, homing works fine. I also tried directly from the printer. Every movement in every direction works but still while printing the Z axis doesn't move. Maybe it's a stepper driver? Any ideas what could cause the problem?

Hello, I have a problem with AXIS version with heatbed an dual extrusion. I did a few successful prints but today suddenly the main power supply went wrong. Screen went black, motors, everything turned off suddenly. Main power adapter light was somehow dimmer. I checked both power adapters and cables are ok. The computer board works when connected via USB. The Marlin software starts. But it doesn't start when power plugged in. Only I've noticed that the no matter which power adapter I use the light on the adapter is dimmer as if there was some weird power consumption from the device. I checked the cables inside if anything was loose, I disconnected power cables from board, connected again like in tutorial but it seems like something is wrong with the board itself. Please advise how to check whats the reason of malfunction.
