Hi,

I use octoprint with a raspberry zero connected to my mk3S ans it's very useful. but the print is sometimes slow, I thin the rasp zero is a little but underpowered..

via prusaslicer it's very useful to be able to slice and upload the code to octoprint and then launch the print.

 I would like to upload the geocode to octoprint and then write it on the sd connected to the printer, and launch the print  reading the file on the printer's SD card instead fo letting octoprint sending the code directly to the printer (because it's slow)

is it possible to do that ?

moreover if the raspberry is shutdown the print can continue..

 

thanks

 

Thanks for your answer.

 

Best regards

Yes you can do that but it's unbeleivably slow. Also you should be aware that the Pi zero is generally considered to be no longer fit for task and should be replaced with either Pi 3B+ or Pi 4 (but not 8GB version).

several possibilities:

- use a faster Pi (3B+ or 4)

- send the gcode to octoprint (without starting the print), upload it from octoprint to sd-card and start the print. Transfer from octoprint to sd-card is very slowly (115200 baud)

- try a flashair sd-card ( https://www.toshiba-memory.com/de/products/toshiba-wireless-sd-cards-flashair-w-04/ )
