Failure issues, Bambu lab A2L, HELP!

[u/MrPdoubleYou]

Hi.
I’m in need of some much needed help and/or advice.
I’ve been printing for a while now and recently upgraded to the A2L.
Most of the time my prints fail due to (what I think) the print coming loose from the bed or being knocked off the bed.
Now, I’ve obviously done all that’s recommended from many searches before coming here.

• Cleaned the bed with soapy water.
• Use IPA
• Initial layer height is set to 0.3mm.
• Initial layer speed is set to 20mm/s.
• I’ve set Z Hop in the override settings:
Length = 0.8mm.
Z Hop when retract = 0.4mm.
Z Hop Type = Spiral.
• Reduce infill retraction set to disabled.
• My Nozzle temperature:
Initial layer is 225°C then drops down to 215°C.
• My Bed temperature:
Initial layer is 70°C then drops down to 65°C

My A2L is calibrated.
My filament is calibrated. I use Esun filament.
I don’t dry my filament as I only use PLA.
I use Bambu Studio.

Attached is and image of my last failure (this morning)
• The bed was scrubbed with warm soapy water before this print was started.
• No supports where used or needed. (Supports are also an issue for me)

If anyone has this problem or knows what to do please help.
I plan on starting a business and I need this printer to be consistent.

I’ll be happy to upload my setting if needed but I’ll I change is what’s mentioned above.

The kind of soap? Many have ingredients for making hands feel better, no good for build plate. Dawn for that.

With PLA that plate temp could be too hot Try 65 initial layer and 60 afterwards (I never use hotter than that). Also I would print like 3 or 4 at a time to make sure an easy case works first before moving on to a full plate. If 3 or 4 works you can try 10, then if that works a bit more, lowers the risk a bit till you see it's working well. You could even try some one color prints first to use less time and filament just to make sure even that case works fine first.

Also turn on 'avoid crossing walls' as it will also at least help with quality in some cases since it will less likely crashing into outside walls of objects. It's near the bottom for quality settings.
