I’ve tried calibration on my MetroX multiple times after it fails the accuracy test. I’ve run it on 3 different PCs running Windows 11 and it has failed at the same point each time on all 3. My main PC has a 132th gen i5, 96GB RAM and a 5070 graphics card. The two laptops are both identical with 13th gen i5s, 32GB RAM and 4060 graphics cards. It is plugged into a USB 3.0 port whenever I use the scanner. Everytime I try to calibrate, it fails with an error sending calibration data to the scanner. I’ve tried every USB port on all 3 computers. I removed RAM from my main down to 64GB. I’ve tried with and without scanning the QR code on the calibration board and nothing works. I get all the way through calibration and it fails at the sending data phase. I’m using Revo Scan MetroX 5.6.9 and firmwar v2.1.81.20250303. I don’t know what else to do. ---

Please give load early version of Revo Scan you can find it on the download page by scrolling down . Try to calibrate it with 5.6.8 Make sure you use good lighting when checking calibration status , but not direct sunlight . If still issues then please contact [customer@revopoint3d.com](mailto:customer@revopoint3d.com) for technical assistance. ---

I suppose it’s time to contact customer service. Even with 5.6.8 it failed. ![Calibration Error](https://canada1.discourse-cdn.com/flex029/uploads/revopoint3d/original/3X/1/6/16ca69df6953356bb5ecb000eddd7b7c500be6b2.jpeg) ---

Sorry to hear that , please contact [customer@revopoint3d.com](mailto:customer@revopoint3d.com) Include the link to this thread for reference. “ Scanning the code is not really nesesery” the issue here is updating the firmware , the calibration file is stored on the computer but for some reason the scanner firmware don’t accept the new data , for that reason you need technical support as there is nothing you can do at this point. Considering your calibration test failed as well ( what is not usual behavior ) , there may be something else at the hand so please don’t wait , and include the link to this thread so the support can see my first evaluation and move to next step. ---
