I’ve been easily printing with my K2 for two days. Today, I upgraded Creality Slicer to the V6.0.2.1574 update. The first 3 prints started and failed (my fault). When I tried the fourth, Slicer could no longer see the printer on the network. It was connected by WiFi. The device was still seen as connected when I went to the device tab, but when I went back to try to print, the pop-up window had no printer selected in the drop down menu, and there were no printers seen in the menu itself. I saw another post here that fixed it by changing WiFi bands. Instead, I plugged it into my ethernet. I disconnected WiFi. The printer was then assigned a local IP address. Creality Print still can’t see it. I downgraded Creality Print to version V6.0.1.1375, which used to work flawlessly. It could not see the printer.
How should I fix this? My next step is going to be factory resetting the printer.
@dapht , I had less problems with *.1.1375 so far than with previous versions. Where I had a similar experience, but in all cases it helped to switch (power of) printer off and on again after a view seconds. I realized that sometimes the printer internally and not accepting any requests from CP6, especially if I have stopped failed prints manually.
P.s.: I am using printer only on Lan and no Wifi. If you can access printer fluidd on http://printer-ip:4408/ you can try also to reboot in there without switching of/on, but in 10% of cases only a switch off will help.
I am having the same issue. I have 2 K2+'s. On a fresh power up on both, creality print and creality cloud sees them both, but at some point after starting a print, creality print will loose connection with the printer but creality cloud still sees them.
I am able to access klipper on both machines when they drop off, so I know its not a network issue (especially considering creality cloud still sees them), and when this happens, a power cycle (and rebind in creality print) brings them back.
I also tried running them over wifi and get the same results.
Had same problem. After last firmware update did a factory reset no problems anymore. Dont need to close/restart creality print anymore can keep it open and print another file.
