Print head access panel opens whenever 2nd nozzle is engaged.

I cannot get the 2nd nozzle to engage without the access panel popping down (see link below)

 

Example of malfunction

 

Is this a common issue? The magnet appears to work until the 2nd nozzle is engaged.

Hi @wscheivink sorry to see you are having problems. 

 

From the video it is hard to tell what is going wrong.

• Could you try to reinsert the second printcore? Perhaps it is not fully inserted.
• When the second printcore is lowered, do you feel a particular spot where the cover is hitting the printcore? 

 

Best regards,

I haven't seen this exact issue but I have seen covers that pop open pretty easily.

 

1) One thought - try prying out the magets in the door slightly.  They should hold much better

2) I wonder if the curved part of the core is hitting the metal plate in the door that controls airflow.  Maybe that metal plate needs to be repositioned slightly.  I think you can loosen two screws and readjust but I'm not very familiar with this.

I've tried this with several different printcores and they all cause this problem even when they are fully inserted.

The cover is not hitting the print core, the nozzle is correctly seated in the silicone brim as well.

Thanks for your suggestions

Well I had a similar problem and prying out the magnets just 1mm increased the strength of the door by about 10X.  I did this quite a few years ago and my door has been fine ever since (never pops open when it shouldn't).
