Many thanks to @WillAdams for re-opening!
I want to give a short update (for anyone who has the same problem and finds this thread through search and wonders if the problems were resolved):
As already mentioned above, I’ve contacted support and told them about my squeaking Nomad 3. They asked me a bunch of questions and gave me some instructions (clean + lubricate rails). But as I’ve already done that a bunch of times without any success, they told me to send in the machine for repair. Last week, about a month later (just want to emphasize that this is not Carbide 3D’s fault - I live in Europe, so shipping takes pretty long) I got my machine back.
I am not totally sure, but I am fairly certain that they sent me a complete new machine (I guess repairing my machine would have probably taken a bit longer, so I guess they decided to send a new one to speed things up (it probably also helped that my machine was only used for a couple of hours of light milling). But nevertheless, very much appreciated from my side to send me a fast replacement instead of letting me wait a few weeks!).
Unfortunately, the new machine makes the exact same squeaking noises as the last one. The high pitched noise begins in the middle of the X rail and the noise gets louder and louder the more I jog the tool to the left. This again only occurs when I jog from “right to left” and not from “left to right”.
Out of desperation I also tried a bunch of things (which most probably won’t make any difference):
- replaced the USB cable with a different one
- used a different power outlet
- moved the machine to a different location (my workbench is really stable, but just to rule that out, I temporarily put it onto the floor for testing)
I also tried to lubricate the X rail. But unfortunately nothing of the above changes anything.
I contacted support again last week - I’ll update the thread when I get a response.
Unfortunately, Fedex also damaged one corner of the shipping box pretty severely. So if support tells me to send the machine back again, I am not sure if I can use the box again (maybe I can patch up the box with a bunch of duct tape) or if I need a new shipping box - which then probably takes longer than a month until I get the machine back.
I know that shit can happen and I don’t want to blame Carbide 3D (I am sure they are doing their best in those post-covid and supply chain shortage times), but I have to admit that I am also a bit frustrated/disappointed at this point. I mainly bought the machine to tinker a bit in my workshop, but also to help my buddy (who runs a local hackerspace) to evaluate the machine for his place. He wants to buy a few new desktop machines soon and only heard good things about the Nomad 3 - so he gave me the recommendations to have a look at this machine for my workshop. I still think it is a good machine, but the machine and I, we definitely have a rough start. Hope it gets better soon.
