I assume you would be running Kiper on it. If so, then what isn’t it compatible it? It rebuillding a printer and you get to choose a display, then by all means use an HDMI touch screen. You can get them for $60 now. But any SPI or USB screen should also work. Mostly the screen attaches to the Pi. BTW, the BTT Raspbery Pi3 clone’s price just “fell throught rhe floor”. They are now under $10 in Aliexpress. This means you have to to buy two of them to qualify for free shipping. (iIt is kind of a no-brainers to buy one %7 Pi3 and pay $$6shipping or to buy two for $7 each and get free shipping.) The BTT Pi3 clone runs Klipper on my printer at about 7% CPU load and 35% RAM usage. Spending even $35 for a Pi4 is not going to make the printer run faster but it would be fun to see the load go from 7% to 4%. The BTT clone has a 12 to 24 volt power inpuit using screw terminals, but the word is “no higher than 12 volts if you want the Pi to live a long life.” I have a BTT Pi3 clone and SKR combo powering my Voron V0.2 “printer for ants” and I’m making very nice prints in ABS at up to 340 mm/second. At 260c nozzel and 105C bed. The combo is not powerfull enough to drive my 80 LED neopixel strip with crazy animations (80 RGBW LEDs updated at 24 frames per second) while printing. I have to tame it down while printing. That is the only limitation I’ve found with the SKR. But do you really need a moving rainbow on the printer while printing? I turned on the effect after the print finished to show it is done. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
