Geeetech

William, thank you for you interest in my problem,

I don't know what I could show you on video! I can show you photos of what I have already printed... But I can't print anything at all now.
If I videoed my machine it would show an E motor not running. All other motors work properly. I use Prepare / Move Axis / 1mm / (E)xtruder but the extruder does not move. What can I show you that would help? Should I use Rambo instead of the Geeetech software to try to make the E motor move?

The E motor works with the X motor wires / cabling. The X motor does not work with E motor wires / cabling . The E motor wires are OK I checked them on X motor, too. I also tried swapping the wires / cabling for E0 and E1 from the inside of the control box.

I switched the little red parts (drivers?) : http://www.geeetech.com/forum/download/file.php?id=1592
from E1 to E0 with no results. I will test and adjust voltage at the potentiometers on the little red parts today.

thanks,
Dave

Still trying to make my extruder work again on my Geeetech Prusa i3 pro A.

I checked voltage to all the drivers. Both the extruder drivers were .806 volts. The Z driver had .772 volts so I raised it slightly.

I heated the nozzle to 190 degrees to be sure that the extrude should move.
With E0 wire connected to the Y axis socket (inside the control box) the extruder moves. The Y axis did not move when connected to the E0 or E1 socket.
My configuration (Control) has 93 steps for E axis. What number should work best for " Vmax e:"?I have tried settings from 999 down to 45. What ever I use does not make the extruder move.

Can you tell me how to activate the second extruder (E1) to use that circuit on my extruder?, please.?

thank you very much.
