Hi Mark,

I finally make it work. Problem possible come from lagging of stepper power when they have to share the current. I remove one of top holder out and now both of them can turn, I will figure out later how to make the mechanism better. Now I can also do the auto homimg. I found out that end ...

Hi Mark,

It does not work. I checked voltage, at first it was 0.8 V. I turn it to be 1.2 V, but result is the same. I check all of the rest driver, they are all only 0.8 V. I check all voltage to stepper connector, they are all 12.67 V. What should I do next?

Hi Friend,

I just finish assembly my i3 3D printer. I suddenly found problem. My printer cannot home and Z-axis cannot move both up and down. I checked jumper for motor driver. They are correctly set for A4988 chip. My main board is GT2560. I test by swapping connector of Z to X axis, it work just ...
