Formated SD card on computer.
Why do you say there’s supposed to be a roller rather than a gear?
If the ET4 can do it, and I suspect it can, I would format the SD card on the printer. The option might be called initialize or something like that.

Because there “appears” to be half of a two piece roller on the screw that holds the belt in place. I am only guessing at what is really supposed to be there. The piece that is there (what I am calling a part of a roller) is not wide enough to support the whole belt. Roller or gear, I just do not know what is supposed to be there. I just want whatever is supposed to be there so my printer is operational.
Ok on trying to format SD card on printer.
I would think the rollers at each end of the X axis would be the same. I’ll check my printer once it’s finished the current print job, but that could be a while.
It makes sense to me that there would be the same gear on both ends of the X axis. Maybe the previous owner put the half roller on by mistake. Maybe he had it apart and forgot to include the other half of the roller if there was supposed to be on. I just don’t know.
