Hello, I am using Prusa i3 3D printer. When I extrude manually some filament from extruder using Pronterface, the extruder motor does not respond. Does anyone had this issue?

Have you tried varying the potentiometer? Sometimes the current being supplied to the motor may not be sufficient to get it working]]> gnex16 Reprappers Fri, 10 Oct 2014 08:17:39 -0400 https://reprap.org/forum/read.php?4,415965,416306#msg-416306 https://reprap.org/forum/read.php?4,415965,416306#msg-416306 I even tried switching another pololu driver, still it does not work.

Any changes to be made in pins.h file for ATMEGA2560, marlin firmware?]]> prashantdshinde Reprappers Tue, 07 Oct 2014 01:07:17 -0400 https://reprap.org/forum/read.php?4,415965,416272#msg-416272 https://reprap.org/forum/read.php?4,415965,416272#msg-416272
oh, and also double check to make sure you have it set up with the correct pins the your firmware.]]> gmh39 Reprappers Mon, 06 Oct 2014 20:14:09 -0400 https://reprap.org/forum/read.php?4,415965,416171#msg-416171 https://reprap.org/forum/read.php?4,415965,416171#msg-416171 I have done it correctly everything you mentioned.
Also I swapped the pololu drivers and checked, but no success....

Is your hot end heated up?
Can you move using the manual controls?
Is your current set properly?]]> gmh39 Reprappers Mon, 06 Oct 2014 14:22:40 -0400 https://reprap.org/forum/read.php?4,415965,415965#msg-415965 https://reprap.org/forum/read.php?4,415965,415965#msg-415965
