Install Klipper, Mainsail, and Octoprint with Multiple Instances Using KIAUH on an Old PC or Laptop

[@georgemitchell2288]

Have you actually installed more than one printer to Mainsail? I can use Octoprint on 3 Marlin printers with no problems, but I can' t seem to get my 3 printers to work simultaneously with Mainsail. Moonraker always gets the printers confused even though the printer. cfg is pointing at the correct directory, mainsail.cfg is pointing at the right directory, and they've all been configured with Kiauh for multiple printers.

[@minimal3dp]

I have 3 printers hooked up and running. Can you see the “Printers” above the Dashboard button in Mainsail?

[@georgemitchell2288]

@@minimal3dp I can install 3 printers but I cannot run the 3 printers under Mainsail. They error out as a moonraker configuration error "unable to find config." What version are you running of Mainsail? I'm running 2.4.1, klipper v0.11.0-6-g336cc92a, and moonraker v0.7.1-780-gdde9bcc.

Been using Octoklipper since I installed klipper. But I'm curious about trying fluid yet didn't want to uninstall octoprint just in case. Safe to install both? Using an old laptop running linux mint for my server. Love to try it out without messing with octoprint, for now.

Cheers for explaining all this, I'm looking forward getting this all done myself. I have two Prusa Mini clones for very rapid prototyping, an Ender 3 that runs buttery smooth, in case i need a larger print bed and in the mail i have a X5SA Pro, to print huge things. they sent me a X5SA-400, but that is another story, i think i really want the "smaller" one. It seems all of them can benefit from Klipper. I also have an unused Thinkpad X230 that was replaced a few years ago by a T480s. The goal is to have each printer on a wifi enabled power socket, so that i can do it all from the comforts of my Ikea office chair. Anyway, you should check your microphone, it sounds horrible ;-). I develop speaker networks and have bought a UMIK-1, a calibrated USB measuring microphone. It's perfect for Zoom calls too. I highly recommend it, maybe it could help you get better sound as well.

[@minimal3dp]

I can't seem to get the sound right. It has been a struggle. Unfortunately, I have had to be self taught on the audio and video. I will try a different setup this weekend. Otherwise, I hope the video help.

[@citronski]

@@minimal3dp Sounds to me like the speech compression used by bluetooth in headset mode. I think any wired microphone will fix it.

[@minimal3dp]

@@citronski I will give it a shot. I usually move around when I am doing a video so I went with bluetooth. I do have a wired lavalier mic I can try. I appreciate the input.

Hi Mike, do you think this is the best linux flavour to use? I read somewhere that it needs to be a debian flavour for it to work properly, is that correct? got an old desktop that i might attempt to do this

[@minimal3dp]

It has been tested more on Debian flavors. I do the latest Ubuntu server lts. It is light weight and has a huge community. With that said, I am not a Linux expert so I go with flavors that are well known and large communities.

How do you get your printer to show up on the 'ls" at 32:48?

[@minimal3dp]

The printers are there after I ran the KIAUH install. I used custom printer names.

@@minimal3dp so we have to install klipper on the printers first before installing it on the pc?

@@minhjaaa I install on the PC and then install on the printers.

[@mattsmalley5780]

Thanks for a great video. Just wondering if you can help me. I’ve managed to install Linux on an old laptop Ive got and got klipper installed and I have build the config files for both my printers and I’m using Mainsail. I’m quite new to all this so hopefully I make sense. My printers are a Ender3 pro with the 4.2.2 board and a Ender3 V2 also with the 4.2.2 board. When I connect 1 printer to the laptop it all works perfectly. If I unplug that printer and connect the other printer it works perfectly and I can print from mainsail etc but if I try to connect both printers at the same time it will only connect to 1 and it losses connection to the other one. I can only but assume it’s because the MCU ID’s are the same? Can I use different usb ports on the laptop? One for the pro and one for the v2? If so how would I do that please? Thanks for your time

[@minimal3dp]

Do different ports for the different printers. Configure 1 printer and set it up. Reboot with that printer unplugged and the other unconfigured then plugged in. Set it up. Reboot with each printer plugged in to their port. They should each be on a different port. Let me know if that helps.

[@exchanginq5215]

Hey i wanted to know how many printers can one pc control using octoprint and klipper.Thanks for the tutorial.

[@minimal3dp]

I have done 3 on 1 computer but your limit will probably be you number of USB ports.

[@exchanginq5215]

@@minimal3dp you need to connect each printer via usb?

[@minimal3dp]

@@exchanginq5215 Yes you do.

[@curly_luke]

Great tutorial! Could I use this on my Pi4 2GB to install 1x Klipper/Moonraker instance with Mainsail as a web interface for Voron and 1x Octoprint instance for my MK3s?

[@minimal3dp]

I think so. Might meet to make sure speed is acceptable but my guees is you will be good.

[@curly_luke]

@@minimal3dp just found cheap touch screen laptops, Yoga 300 and I think it's a steal compared to Pi's. In my country around 70$, Pi with a screen would cost at last twice that amount if you even could get one.

[@DNozz777]

When installing Klipper with Kiauh, when I add tmp/printer to the list of serial ports it doesn't show up in the drop down.

[@minimal3dp]

Is your user part of the tty group?

[@citronski]

BTW, the desktops don't have GPIOs, one of the main features of RPi. I'm stumped why nobody has created a USB-to-GPIO alternative for PCs yet.

[@minimal3dp]

I am sure it exists somewhere.

[@citronski]

@@muller86wolf Of course, why didn't i think of this? I have countless Arduinos drifting around, even the less than 1$ DigiSpark has GPIO and USB!😅

You said you use windows subsystem for linux; Im running win 11 then powershell type the ssh username but I get a "ssh: Could not resolve hostname username : No such host is known. My main computer is connected directly to my router but the pc is running wifi. Not sure what Im doing wrong

Try checking your router and looking for your machine's IP and connecting with that. I had an issue when I named my machine m3dp1.local. I never could connect with the ".local"
