Question Regarding Carbon Fiber Rods and Printer Maintenance

[L0rdS474n]

I have a question regarding the carbon fiber rods and cleaning. There was no indication that the print quality was affected, yet the printer suggested it was time to clean them.
I thought I’d follow the printer’s recommendation to stay aligned with the maintenance guidelines.

However, I couldn’t detect any dirt on the cleaning cloths during the process. My question is: what triggered the printer’s alert? Is it time-based when printing with ABS/ASA/CF materials, or was it just the infamous gremlin acting up again?

There was genuinely no dirt, unevenness, or any issues with the rods, so I’m unsure why the warning appeared. In any case, I performed extensive maintenance on the printer to keep it satisfied for a while longer.

Perodic maintenance alert ? its similar with the A1 , i also take it as a hint that the rails are becoming dry and prohibiting bed movement (y axis especially) , which im assuming could be a factor in print deformation (layer shifting) and that kind of issue

The printer isn’t old enough for carbon rod cleaning to be part of its periodic maintenance, but maybe it was just a scheduled alert. The print that triggered the warning looks just as good as the one after my full maintenance, so…

Does A1 use Motor Current Detection On X Axis limit detection

When A1 is homing part of the process is going to the very left of the x axis. I wonder how it knows the limit. It doesn’t use switch, a hall effect sensor, and less likely an encoder. An Idea cameout to my mind maybe the plastic cover or the purge wiper is the reason. I think A1 utilizes some kind of current spike detection. Well motors draws more current under stress. Maybe I’m wrong I’m gonna test it soon by blocking the toolhead intentionally

Maybe this will be of better use , i googled hall sensor , after a personal experience

Could be something like that! Either way, it’s had all the service it needs to keep going for another stretch.
The little rascal beat me to it — I had planned to do maintenance this weekend anyway, as I like to perform it regularly to nip any potential issues in the bud, so to speak.

I receive monthly maintenance alerts on the scren of my X1C, whether I’ve used the printer or not. I usually keep tabs on when I use my printers and the maintenance I’ve performed on them, and although most of the time i do give in and do the maintenance, I’m not at all convinced that’s really necessary (especially when the respective printer was not used). I’m now certain that’s just a timed reminder message, not being dependent on the amount of printed filament.

It sounds like it’s purely time-based, then.
I do the same as you—track usage rather than relying on a timed reminder.
There’s no need to perform maintenance on an idle device in this case.
