The "171h" error is usually a temporary roadblock, not a permanent failure, often resolved by updating the USB driver. If you'd like, I can:
If external checks yield no improvement, the issue is internal. Disconnect all power for at least 10 minutes before opening. High-voltage capacitors can hold a charge.
The most authoritative source for the fixes in version 17.1h is the Geomedia (the developer of Covadis) Customer Area . You can typically find: Correction Lists covadis 171h fix
If your 171h is a pressure transmitter or actuator with position feedback:
: Detailed logs of bugs fixed from version 17.1g to 17.1h, often relating to object visibility in AutoCAD or specific calculation errors in earthworks (terrassement). Compatibility Updates The "171h" error is usually a temporary roadblock,
While official changelogs for specific sub-versions are typically restricted to licensed users, updates in this series generally focus on several core areas. Common Targets of Covadis Maintenance Fixes Software Interoperability:
The 171H utilizes a complex gear train to achieve its feed rates. If you hear a high-pitched whine that wasn't there before, or if the feed becomes erratic, you are likely looking at bearing failure in the quill . The bearings in these units are high-precision angular contact bearings. They are expensive and difficult to source, but they are the heart of the machine's accuracy. Once they go, the runout increases, and the machine becomes useless for fine work. High-voltage capacitors can hold a charge
Look for the .cuix file corresponding to your version (e.g., Covadis2022.cuix ). Select it, click , and close the dialog box. Step 3: Apply Registry and Compatibility Fixes
Ensuring the software runs smoothly on specific versions or service packs of Tool Enhancements:
For enterprise network licenses, maintain updated server-side license manager software to prevent intermittent communication drops during active calculation routines.
