Z axis not moving The X and Y axes work just fine, but the Z axis doesn't move. I'm using a Folger Tech Prusa i3 Acrylic. https://reprap.org/forum/read.php?262,459138,459138#msg-459138 Mon, 13 Jul 2026 17:04:48 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,459138,459207#msg-459207 Re: Z axis not moving https://reprap.org/forum/read.php?262,459138,459207#msg-459207

Try set the vref on the stepper a little bit higher.
Lower the z-axis speed and acceleration in marlin.

I've already tried up to 0.480 V on the vref with no success. I'll test the speed stuff.

Has it ever moved? Have you changed the motherboard type in Marlin (configuration.h) to 33?

Nope, it's never moved. Yes, the motherboard is set to 33 in configuration.h]]> zachsents Printing Thu, 22 Jan 2015 17:35:42 -0500 https://reprap.org/forum/read.php?262,459138,459175#msg-459175 Re: Z axis not moving https://reprap.org/forum/read.php?262,459138,459175#msg-459175 Lower the z-axis speed and acceleration in marlin.]]> gforce1 Printing Thu, 22 Jan 2015 16:47:31 -0500 https://reprap.org/forum/read.php?262,459138,459160#msg-459160 Re: Z axis not moving https://reprap.org/forum/read.php?262,459138,459160#msg-459160 MindRealm Printing Thu, 22 Jan 2015 16:31:38 -0500 https://reprap.org/forum/read.php?262,459138,459138#msg-459138 Z axis not moving https://reprap.org/forum/read.php?262,459138,459138#msg-459138 zachsents Printing Thu, 22 Jan 2015 16:08:32 -0500
