Good afternoon. I have a Prusa I3 dual extruders with a GT2560 board. I have been troubleshooting this machine for quite some time and after resolving a power and connection issue, it seems that the Z axis positions itself too high above the bed when I start a print. Is anyone familiar with this type of machine that could help me troubleshoot this problem? Please let me know…
Should be a little adjustment screw on the left side of the machine that you can adjust Z height with. Back out the screw a little bit to lower the Z axis, but do pay attention and don’t ram the nozzle into the bed.
