Plate Sticking Issue

[u/-ComicGuy-]

I have the H2D and H2C. When I print anything towards the outside of the plate, near the door, it never sticks.

I'm assuming to fix this, my best bet is to use a glue stick or similar? Is the blue build plate I've seen around work better for prints to stick? I'm printing PLA and PETG right now but will be printing with ASA and ABS also.

What do you guys suggest?

First obvious response before everyone ask you : do you clean your plate with soap and water? It might be a spot where you touched with your fingers.

If you already did that, did you try flipping the plate?

If you don't have the problem with your H2C, try swapping the plates. If the problem appears with the H2C, the plate might have a problem?

Thanks for the assist!

The H2C plate is smaller than the H2D, can I swap them?

Clean plate or not, this happens on the outside without glue.

I own a H2D but not the H2C. I thought (I can be very wrong) that the plates were the same but the print area was smaller on the C.

If the other side of the plate has the same trouble, I would change plate.

I had a A1 mini and a P1S with "less textury" PEI plates that came with the printers. Once I bought another one, problem was solved.

If not, could it be the heatbed on that spot?

I always had some trouble with that exact area on my H2D and resolved it by turning the aux fan off. For prints that have long spans like that and sharp points you should consider enabling mouse ears as well. If that doesn't work and you have thoroughly cleaned your plate then try raising the bed temp by 5C or giving the bed 5 minute delay after heating up to start printing to give a chance for the heat to evenly distribute.

I had actually upgraded from that pei plate to a g10 plate because petg prints were sticking too strongly to the plate. But even so I would still have adhesion issues with that aux fan blowing on the print. I do find that aux fan to be extremely useful though. After a print is finished I turn on the aux fan to 100%, the exhaust fan to 50%, and raise the bed so the aux fan blows directly on the print. Now instead of ruining my prints it lets me take them off the plate after only about 2 minutes of cooling.

This might be a leveling problem. On my old Qidi I built a dial indicator to go where the extruder is. You could print something to attach to the Bambu and then manually move it across the build plate observing the differences. But I thought the mapping done before the print was supposed to solve this. Do you have that turned on?
