So I recently got the " He 3D - XI3 High Precision NEW prusa I3" kit. I assembled it and wanted to start printing. So I installed Printer Interface on my laptop (pretty much program where I can just press to move any of the axis). The axis that I'm having problem is the z-axis. When I press to move it for example by 10, there is loud sound like the motors are trying but nothing is happening. The motors are not even spinning. Sometimes when I keep pressing it one of the motors spins little bit and then stops. Anyone experienced this problem? If you don't understand my problem please ask. EDIT: I tried to run one f the z axis motors and it works. It fails when I plug in both of them and try to run them at the same time. EDIT2: So I rewired and connected the two motors. I just connected them and threw them on one pin instead of two. Now the problem is that they don't spin equally. What I mean is when I run the Printer Interface and put let's say 10mm run increment, the motors don't run equally (one spins more then the other), which is super confusing as they are supposed to spin equally (right?) if i connected them together. https://reprap.org/forum/read.php?406,602322,602322#msg-602322 Wed, 19 Aug 2026 16:09:08 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?406,602322,603995#msg-603995 https://reprap.org/forum/read.php?406,602322,603995#msg-603995
Another thing to check for is your microstepping jumpers, you should have little black clips that go under the stepper drivers on the ramps. Weird things happen when your firmware thinks you have more or less installed then what you have in reality. My HE3D instructions didn't even tell me to put them in.]]> AudaciousTuddle Prusa i3 and variants Sun, 03 Jan 2016 11:49:00 -0500 https://reprap.org/forum/read.php?406,602322,603780#msg-603780 https://reprap.org/forum/read.php?406,602322,603780#msg-603780 Roger123D Prusa i3 and variants Sat, 02 Jan 2016 23:56:28 -0500 https://reprap.org/forum/read.php?406,602322,602337#msg-602337 https://reprap.org/forum/read.php?406,602322,602337#msg-602337 I had to reduce mine from 5 to 3 by sending "M203 Z3" through your printer interface. If moving Z works, then send "M500" afterwards to store the new value in EEprom.

1. Please check if both steppers are driving in the same direction, if not, flip over the stepper plugs of the stepper that has the wrong direction

2.the setting of the z stepper current is too low. Increase a little bit by turning the potentiometer clockwise untill the steppers are running.
Be aware that if the current is too high you can damage the driver. You can check it measuring the reference voltage too.

Kindly regards
