Raspberry Pi 4 Stability Problems

Hello Friends,

I updated my raspberry pi 3 to 4gb raspberry pi 4 in order to get better performans. Then i made all configurations but i have a few problem:

-Have stability problem with nextion hmi screen (which i didnt have with raspberry pi 3). When i use z axis with fast repeats from nextion , rpi is freezing 10-20 second, ethernet connection is lost on web interface etc.
I tried it on rpi 3 again, did not have same issue. Whyen rpi4 freezing, nanodlp says 125-130% cpu usage. On rpi3 it never goes up to 5% with z axis movement.

-Raspberry Pi 4 have slower slicing speed than rpi3

If you can help me, it could be perfect.

Best Regards
Cihan

Re: Raspberry Pi 4 Stability Problems

Stability: it seems kind of noise, please share a debug file
Not sure how it is possible to have slower slicing

Re: Raspberry Pi 4 Stability Problems

I reinstalled raspberry pi os lite and nanodlp clearly, touch screen problem solved. I will test again slice speed between pi4 and pi3. If issue continue i will share debug file. Thank you for your fast response.
