I found a REVOLUTIONARY web app for klipper printers. Slice and Print from your phone, REMOTELY!

I've been using this new web app (Hotend) with my QIDI Plus 4 running Klipper for a short while now, and it's fixed one of my biggest frustrations with remote printing.

I can find a model on my phone, upload it, have it sliced in the cloud using my ACTUAL printer profile, send it straight to the printer and start the print. No firing up the PC, no USB sticks, no messing around with port forwarding, EASY.

It's also got live webcam viewing, timelapses, filament tracking and a print queue, some of which moonraker already offers. The agent it uses is **open source** and only makes outbound connections, so you're not exposing your printer to the internet and keep all your models secure, which to me isn’t an issue because i am not a CAD guy.

There's a virtual printer you can try on the sign up page if you just want to see how it works before installing anything, for those cautious creators like myself.

For me, the biggest difference has just been how much easier it makes printing when I'm away from my computer, especially at work and i want something done before i get home. Time Saver!

Let me know your guys’ thoughts. Do you have something similar that you use? Is this the next best thing?

I understand that cloud based slicers have a bad rep on forums but it genuinely helped me out so id thought i would share around. I also looked into it and they have a decent privacy policy so who knows what to make of it.
