SOLVED More than one Raspberry pi connected to Cura

[Lakes_Rivers 1]

Hello fellow makers,

New to the 3d printing forums, so I apologize if I have posted this incorrectly. I own two 3d printers and have both of them hooked to a Raspberry Pi 4 (each printer has a RPI). I have been using Cura to send prints to one printer on Octoprint on my wifi network. I do have the two printer profiles in Cura that I've been using before I setup either printer on a RPI . Only recently I hooked this second printer up to a RPI and I'm having trouble getting Cura to recognize two different API keys. In my printer profiles I have changed the api and ip address to match the two printers. However it just keeps sending the prints to only the original printer and can't seem to get it to recognize the second one. As I stated I have to IP addresses and two profiles. How do I get Cura to send prints to both? Again, sorry if posted in the wrong area, any advice will be appreciated. 

Thank you!

Hmm,, hard to say what the problem or reason, but I can say it works without problems normally. I have 3 printers, each with a PI connected to my network and configured normally in Cura. You have to create separate printers in Cura and each printer has its own connection with IP and API key for sending the job to Octoprint. Never had any issues with it.

Good to know. Still trying to work this out. I do believe it is within Cura but not certain. I do have two tabs opened on my browser one for each printer in Octoprint. In cura I can send a print out from either printer profile but no matter what, both prints will show up in the original printer I created on Cura. Each printer in Octoprint has a separate API key. But Cura seems to only accept one as valid. I can drag and drop a print from Cura into each printer in Octoprint. So I know at least that I can print on both printers between both programs. I will play a little more rough with Cura and see if it listens. Thanks for the input.

In the Cura printer settings, you have these 2 printer profiles and for each printer you have a Connect button where you can set the Octorprint instance and the API key. So you have to configure it for each printer. Maybe check that again and don't forget that you have to activate the printer you want to configure before.

Alright, problem solved! I ended up just deleting both printers on Cura and starting over. Honestly, I think the simple problem was (user error) and the fact that I was trying to add the second printer onto Cura when the first printer and Pi was powered up and running, maybe causing some conflict. This time I added ip and api with only one printer and pi on at a time. And it recognized it! I appreciate you for even just giving your input. Help me do the process of elimination. 

Thank you!!

Glad that it works now and thanks for the feedback!

 

Happy printing 🙂
