I don't know how but it happened

Bambu Lab H2 Series

Well, yes, I don’t know how I could have done it, but I did it.
Last night, my H2S finished printing and parked as it should.
Then I arrived and, using the manual touchscreen controls, instead of pressing Y-, I pressed Y+, and the machine’s axis hit the end of its travel, making a motor noise like “rat rat rat rat.”
My question is simple: did I damage something?
I tried starting another print, and everything seems fine, but I’m a little worried.

Its fine. These motors can only apply so much torque before skipping steps. Same thing happens when you start a print, while the bed is at its lowest point. Because it tries to go even lower, before raising

Thanks, I’m glad to hear that.
Do you think something might have gone wrong with the gantry squaring, as the Y-axis hit the bottom at the end stop?

No. Should be fine. These printers protect themselves pretty good.

Thanks for your reply, I feel more at ease now.

Ps. I still wanted to ask you:
After what happened, is it necessary to perform the tensioning procedure for the X and Y axis belts or can I avoid it? The printer has 35 hours of work.

You should be good. It wont hurt to tension or even recalibrate things, though. These belts wont stretch that easily. For example, I’ve crashed my voron at full speed, many times while setting up the .cfg. Like 5 times a day when I was setting up the max speeds. 30k acceleration 1000mm/s crashing. I break plastic parts sometimes but never do any permanent damage. The steppers will skip steps before it hurts itself in a permanent way

I understand… thank you very much for your availability.
