Hello everyone. I’m asking for help because I have already exhausted research and assistance from Artificial Intelligence Gemini and CoPilot. The problem: I have an operational CNC machine and decided to upgrade to a Duet2 Wifi controller. Everything worked except the Z-axis movement. It always moves 1/5 of the requested distance. For example, if I request a movement (positive or negative) via Web Control of 25 mm, it only moves 5 mm. If I change steps per mm M92, it produces almost no change. I have checked the Z-axis hardware and everything seems ok. Homing is OK. I have no idea what to do. My setup: Duet2 Wifi controller, RepRapFirmware for Duet 2 WiFi/Ethernet version 3.6.1., Z axis Threaded Rod Stainless Steel M8x2mm Nema 23 motors (AK23/15F6FN1.8 model). Power supply 12v/ 30A), mechanical endstop switch. Attached Config.g e Diagnostics.

The Z-axis Steps/mm remained at 400 the whole time, when it should have been 1600.
A new SD card solved it.]]> MARCENEIRO JOVEM Firmware - mainstream and related support Thu, 27 Nov 2025 18:58:56 -0500 https://reprap.org/forum/read.php?146,897335,897345#msg-897345 https://reprap.org/forum/read.php?146,897335,897345#msg-897345 forum.duet3d.com] where the Duet3D support team will be pleased to help you.

This seems like a lot of acceleration for a Z, perhaps this is causing z to skip steps]]> Dust Firmware - mainstream and related support Sat, 22 Nov 2025 08:35:57 -0500 https://reprap.org/forum/read.php?146,897335,897339#msg-897339 https://reprap.org/forum/read.php?146,897335,897339#msg-897339 MARCENEIRO JOVEM Firmware - mainstream and related support Sat, 22 Nov 2025 07:24:21 -0500 https://reprap.org/forum/read.php?146,897335,897335#msg-897335 https://reprap.org/forum/read.php?146,897335,897335#msg-897335 I’m asking for help because I have already exhausted research and assistance from Artificial Intelligence Gemini and CoPilot.
