hello all, im new to 3d printing and have just bought an ender 5 pro set up was easy ,first print great small owl ,second print great of thingiverse then the third print hot end moved to the middle of the bed ready to print but i had to stop the print as the bed was about 4 mm from the hot end can any body tell me where ive gone wrong and how to fix this as i want to get printing please. thank you.

hi every body,i was hoping some one may be able to help me, as im new to 3d printing.So i bought an ender5 pro, which i put together and did my first print, which i must say was rather impresive, it was the owl which came with the printer, then i printed some oil barrels from thingiverse, and again it was really good, then i noticed that my hot end had moved from where it first started, to a little bit further to the right at the homing position, And that it was also really close to the bed. How ever when i came to print again i leveled the bed as normal, homed the printer after, which went ok then when i pressed print from sd card it moved to the center as normal. But then i noticed that the hot end and bed were a good distance from each other, resulting in me getting spaggetti in stead of a 3d printed part. I am hoping some one can tell me where ive gone wrong and how to fix this problem, as i want to get back to printing thank you in advance and look forward to any help

hi every body just wondering if any one can help. I've just bought an ender 5 pro and i am new to 3d printing, any way i set it up and my first print was great, love the printer, but i feel ive done or touched something i should'nt have as when i try and print anything now i level the bed properly home the hot end and press print from tf card everything goes well till it gets to the middle ready to print then the bed seems to be miles away from the hot end thus just ending up with a pile of spaggeti any help would be very very appreciated
