so I had the board go and replaced it.. and now I cant get the old extruder or new to work. I was always assuming it was the voltage. I had it at .9 and all the way up to 1.1 and still click click click.. I dont wantto crank it up too much since I hear it will over heat. everything I read people had it at around 1.1 or lower.. should I just keep going higher ? or could it be some other issue.. I was reading another forum and they said the DEFAULT_AXIS_STEPS_PER_UNIT should be something like below.. you can see new and old.. //#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,1600,93.5} // default steps per unit for ultimaker #define DEFAULT_AXIS_STEPS_PER_UNIT { 79.3086, 81.111, 394.60, 96.6 } now is that for every system or was that recommended for certain systems ? either way that didnt help when I changed that.. so I guess I'm looking for some guidance on how I need to change my settings or voltage running MKS base 1.5v and 3D Printer MK8 Direct Drive Extruder 0.4mm / 1.75mm for Prusa i3 https://reprap.org/forum/read.php?406,802579,802579#msg-802579 Mon, 08 Jun 2026 16:35:46 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?406,802579,802630#msg-802630 https://reprap.org/forum/read.php?406,802579,802630#msg-802630 amigob Prusa i3 and variants Thu, 28 Dec 2017 05:10:25 -0500 https://reprap.org/forum/read.php?406,802579,802609#msg-802609 https://reprap.org/forum/read.php?406,802579,802609#msg-802609 o_lampe Prusa i3 and variants Thu, 28 Dec 2017 03:26:49 -0500 https://reprap.org/forum/read.php?406,802579,802595#msg-802595 https://reprap.org/forum/read.php?406,802579,802595#msg-802595
(to a certain extent a lot of machines have standardized on the belts so X and Y are generally the same)


Click is often caused by the stepper being incorrectly wired, or a broken wire to the stepper

also if the extruder is blocked...

I would remove the stepper from its frame and see if you can electronically move it. If it moves the issues is probably mechanical.

NB remember that extruders will not move when the hot end is cold, M302 will over ride this, till next controller reboot]]> Dust Prusa i3 and variants Wed, 27 Dec 2017 23:27:35 -0500 https://reprap.org/forum/read.php?406,802579,802579#msg-802579 https://reprap.org/forum/read.php?406,802579,802579#msg-802579 was the voltage.

//#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,1600,93.5} // default steps per unit for ultimaker
#define DEFAULT_AXIS_STEPS_PER_UNIT { 79.3086, 81.111, 394.60, 96.6 }

now is that for every system or was that recommended for certain systems ? either way that didnt help when I changed
that..

so I guess I'm looking for some guidance on how I need to change my settings or voltage
