Re: The Case for the Pi3A+

I agree with bensimmo The trend right now on 3D Printers is to go wireless. Being untethered makes sense. Many people use mobile devices to find things to print. They then use a WiFi server, such as Octopi or Repetier host or others, to carry out the print job. Hippy; Even today most homes and apart...

Re: The Case for the Pi3A+

I think the perfect use for the Pi3A+ is as a 3D print server. Octoprint (Octopi) , a couple of others, would be perfect on one. Needs only one USB. Check Needs WiFi adapter. Check Needs small size for embedding in or under chassis. Check Needs pi3 type power and memory for drag and drop slicing. Ch...

There is the MegaPi board. It uses the Arduino 2560. More storage, more memory, more eeprom. Processor speed is the same as Nano/UNO. GRBL has moved to the Mega2560 exactly for the reasons you stated. In fact they are going to 32bit ARM. The actual connection is serial only pins. It can operate with...

Re: PiZeroW - Reboot and shutdown no longer work

I have this issue also.

I am running Stretch. It worked fine for shut down at CLI and in GUI when installed. THEN I updated and upgraded now neither of these cards will shut down properly. I did add XRDP. But the problem does not seem to be with that added. I think it is something in the updates.

No 2011 is not that old, unless you are a RasPi! Look at the number of iterations there have been so far? Back then (2011) there was a big argument about "Back-Powering" from non-compliant USB hubs. It was true, there was a danger to the boards from having power, in to the power connector, and back ...
