![]() ![]() Also I recommend a powered USB hub when connecting other devices to your raspberry pi. Unless this problem is eliminated or addressed with the new computer, you will still have problems. ![]() ![]() You may have had a power or heat problem. The speed automatically doubles when a command is sent to the printer, or to a remote computer. And since the touchscreen only Sends out coordinates when it is touched, there should be little if any noticeable change in the usage. It shows that my CPU usage spikes at about 10%, Going from. In fact i downloaded a plug-in for octoprint, to monitor usage it's called "resource monitor". And i have not experienced any slowdowns whatsoever. However, I have been using a USB capacitive touchscreen on my Raspberry pie for approximately two years. Shipping there is about 5bucks but even so they beat Amazon after the coupon.įirst of all, I do not have a official raspberry pie touchscreen, so I cannot comment on how it works. I took a screencap of my Pi3B+ running with TouchUI with it displayinig the camera feed below.Īlso, and related, Adafruit has the Rpi4's which are a good deal right now with their black friday coupon (ADATHANKS for 15% off) - but save one for me :D (once I decide on which one I need to get). Right now, with what I have running (Logitech c525 1080 webcam, 5" USB/HDMI touchscreen) it seems even 1G would be OK (and not in swap) so I question that I need 4GB (but 2GB seems like good compromise). ![]() I can't think of anything offhand that I may want to add in the future that could suck up extra memory, but I'm not very imaginative about these things either. I would probably go with the 2GB version since it is 10 bucks cheaper, but if there is a reason to use the 4GB version I could do that. So I am considering moving to a Rpi 4, but wanted to see what folks thought about the memory options. My primary concern is stability and I don't want to have to limit using the touchscreen during printing for fear of causing a slow down. I am setting up the 2nd Pi with a screen and took a look at the processor utilization when running TouchUI, and noticed that CPU can get up there when bouncing around though the menus,(edit - I was intentionally trying to run the processes up to test, by quickly bouncing through menus) and having a camera attached does not help. Hi, I have been running Octopi on 3B+ boards for some time, with all but two of them running without a screen. ![]()
