Problem with Z steper motor and Z rod brace ,need advice

so today i decided to use auto bed levling to check if my bed is still flat as last time ,and noticed that both points at Bed equation points [60.0, 0.0, -0.409] [60.0, 180.0, -0.517] are off by ~ 0.5mm ,which is to me strange that those 2 are probably the hardest to change by so much , while looking at the Z arm i noticed that the brace that holds the z motor and the Z Smooth Rod in place is cracked!



This would couse the Bed to be off by that much? or atleast make the X-Arm sag down that much.

AND i have found the couse of it

I was using These:



[www.thingiverse.com]

They were working so great , printer was so quiet only thing i could hear was the fan on the hotend. Kinda sad that i wont be able to use them anymore . if someone got any idea of a better design let me know please
The one that comes under the Z motor was probably taking too much of a strain on the brace becouse it was not designed to carry the weight of the printer.
I also notice that the foot is a bit bent at the bottom of the Z profile so will have to print thatone too.

But to the Advice part:

Will i have to disassemble most of the printer to fix this part? or can i just unscrew it and replace and hope nothing shifts?

The anti-vibration unit that you had under the Z motor was in he wrong place. It should have been under the foot at the bottom of the Z extrusion.

Hope that helps

Thank you for the advice ,it wasnt ment as anything wrong with your design ,just the guy who published it on thingiverse said it was to go under the Z motor and i did as it said , was worried abaut something like this will happen ,but did it anyway. When i fix this i will put it under the Z foot.

Otherwise excelent work appjaws ,they make the printer really quiet
