I’ve had my snapmaker for 3 weeks now. I’ve successfully printed a few times and miserably failed a few more. I’m a noob so I can understand that. I have a very substantial problem though. After the first week of printing one of my z linear modules locked up completely and the printer was dead. I contacted snapmaker and they sent me a replacement that took another week. I got it put back together and started printing again yesterday. I’ve run a few good prints in a day and a half and now the other Z module has failed. Is this a common problem? Are all my rails going to fail one by one until they have all been replaced? Now I’m dead in the water again and I have to wait for another new part to arrive then take the entire thing apart and reassemble it for a third time… Needless to say I’m not happy with this mess. I’ve asked snapmaker to save us both the trouble and send me 4 more modules since I expect the others to fail soon as well. Am I alone in this? ---

Unfortunately you are the only one who had 2 defective modules, i guess. Here are some threads about Linear Module defects: > [@Linear module stopped working after third print](https://forum.snapmaker.com/t/linear-module-stopped-working-after-third-print/8240): > > I took delivery of my A350 a few days ago. Two test prints were successful. Today’s print, the third, didn’t finish successfully. About three vertical centimetres before the end of the print, there was a bulge, suggesting a problem on the Z axis. At the end of the job, the percentage completion stayed at 100% for over an hour, with the print nozzle still on the printed piece, before I turned the machine off. Since then, one of the vertical linear modules no longer works. There is no motion… > [@Y Linear module Fault](https://forum.snapmaker.com/t/y-linear-module-fault/7486): > > @Edwin I think I have a similar fault with my A250 linear module as mentioned in another post. [[A250 Y axis fault] ](https://www.youtube.com/watch?v=V0Dw2sEQj60) the Y axis is making a terrible noise and it seems to twist when it moves like one of the motors is not working. I have reseated all of the cables for the Y axis and have updated the firmware to 1.9. I have attempted to recalibrate the bed and the print nozzle has left a deep impression in the top left of the print bed - just visible on the ‘250 white line’ next to … > [@HELP !
