It looks like you're dealing with warping issues during your ABS print. Warping can occur for various reasons, but in this case, it seems to have happened mid-print. Here are a few possible causes and suggestions for prevention:
Insufficient bed adhesion: ABS tends to warp if it doesn't have a strong bond to the print bed. Ensure that your print bed is clean and properly leveled. Additionally, try using different bed adhesion methods like a brim, rafts, or using a strong adhesive like ABS juice.
Temperature differential: Although ABS warping is more common at the lower layers due to temperature differences, it can still occur during the print. Consider enclosing your printer to maintain a stable temperature around the print area. This will help minimize temperature variations that lead to warping.
Cooling: Ensure that there are no drafts or sudden changes in environmental temperature around your printer. Sudden cooling can cause the plastic to contract unevenly, leading ...
When the speed is increased it moves side to side which causes it to shake and this can lead to the fillament cracked and separating from bed like the photo shows
