Greetings, Today after finishing a 3d print I found the z-axis in the middle position. I tried homing it but it seems stuck at one end. I switched the machine off and on again but didn’t work out. What could be the problem? and is there a quick way to fix it? Thanks Yasa ---

File a support ticket and get the module replaced under warranty. ---

It’s either dead or there’s a problem with one of the limit switches. Contact support and they’ll either tell you to open it up to check it or they’ll replace it. \_S ---

Thanks for your reply @eh9 @sdj544 I’ve raised it to support and awaiting their reply. I’ve removed the x-axis and tried to move the z-axis; one side moved and the other didn’t, so it seems that one side it dead ---

You can try (with power off) unplugging and replugging all your cables (don’t just make sure they’re seated, actually unplug them.) For a lot of people that seems to work. You can also try plugging each axis separately into the x-axis port and see if they work individually. (make sure they’re uncoupled doing this. -S ---

Thanks sdj544 I’ll try that. Support just came back saying the linear module is damaged and need to be changed. The problem it’s just over 1 year already so the warranty is over it is going to cost me over 150 usd. ---

So at this point you can ether decide to replace the one rail or upgrade (sidegrade? downgrade?) to the all new rails. The price for all 5 with the 50% discount isn’t much more than the price of 2 old rails. Not sure if there’s a backorder on new ones. Maybe ask support? -S ---

you are right sdj544. Though I’m disappointed of the quality of the machine. I’m not a heavy user. I didn’t use the CNC module yet. Even the laser engraver I just used it for 30 mins to test it. I was only using it for 3d printing over the past year and I consumed just 2 KG of filament over the past period (I don’t think this is heavy usage). The machine is kept in a well ventilated room and within the closure all the time. Would I be expecting to change these every year?? ---

I’ve been running the original rails with heavy cnc usage for more than a year and a half with no problems. (hope I didn’t just jinx myself). Well, no problems other than having to adjust the play in the brackets. So who knows. There seems to be a lot of variance in problems and QC. There was a batch of rails around Sept. '20 that kept burning out and had major problems. Haven’t heard of anything like that for awhile. Mostly just Luban and firmware issues now. -S ---

then it’s possible that I had a bad batch. Probably it took longer to malfunction. I’m checking with support again, if they would replace it for me. thanks anyways for your feedback ---

well support came back saying that don’t similar cases so it can’t be a problem with a certain batch, so they won’t exchange the module and I have to pay for it. This makes me more worried as it means overtime more and more issues will arise I received the machine just around end of October 2020, so it’s almost now 1 year and 3 months old. With my minimum usage, I’ve already had to replace the heated bed last month and I had to pay for it and now this issue. Honestly; I’m very reluctant to invest more in snapmaker now. ---

so interestingly, support don’t want to admit there is a problem with the module and don’t want to give any explanation why the module failed with such a minimum usage.
