Prusa Mini & Octoprint

Hi,

I am trying to use octoprint with my Mini but it doesn't work. When I hit connect I got the following message :

No more candidates to test, and no working port/baudrate combination detected.

I am 100% sure that it doesn't come from the Pi. I have tried it on my Mk3S and it works fine. Is it possible to check the status of  the micro USB on the buddy bord?

I tried 3 different micro USB cable.

Thanks

What are your exact connection settings?

Hi Chuck,

I just fixed it. I have couple of micro USB and only one is working (out of 6). I do not see any difference at the tip. The only difference is the length of the cable. 

I have to keep that one safe and label it Prusa mini octoprint. 😀

Thanks.

What is the length of your good cable? I'm using a 3 foot cable and it works fine.

RE: Prusa Mini & Octoprint

I am using 12 inch cables because they work.  I had a 4 foot and it failed.

Hi,

It is a very short one (150mm). The cable was delivered with a wireless mouse so nothing very specific about it.

The ones that failed are not longer than 1.5 meter. 

Sorry guys, I do not use imperial. 

Completely different subject but why can't I have access to the data in the USB stick while connected to octoprint? 

On my MK3s I can print from the SD card and octoprint.

Am I missing something on my setup?

Hi, I have the same issue 🙁 Tried cables from 15 to 105 cm - approx. 6"-40") but no change, still getting "No more candidates to test, and no working port/baudrate combination detected." message. I'm using Pi Zero WH so I need microUSB-microUSB or microUSB-USB A with conversion...any recommendation to solve it? 😕

Hi Jakub,

Changing the cable solved my issue. If you are sure about raspberry pi setup then I will suggest to test more cables. 

If possible, try cables that are used for similar application and not something used to charge a power bank or toys. 

You could probably ask PRUSA for more details, they might recommend some cables.

Hi,

Not really. There is a step by step and a video to help with the install. 

Link below:

In my case I had a second printer (Mk3s) and the pi was working fine so I assumed it was either the prusa mini or the cable. 

Do you have a second printer that is not a prusa mini?

CableCreation Micro USB to Micro USB OTG Cable, Male to Male from Amazon is the one I used. But before it arrived, I ended up collecting all the USB to Micro USB cables (5 total) in the house and tried them. The one that worked was from my Kindle.

I had the same issue when i set mine up. The issue is the cable there are two kinds of cable there is a receiving only and a dual receiving and sending cord. The later is a thicker cord most of the cords are the cheaper recieving only.

Thank you all, guys! The problem is solved by using "both way" cable.

RE: Prusa Mini & Octoprint

I think it`s 100 cm (approx 39") but I my opinion it does not metter the lenght...most interesting is to be "both way". If you even buy "data USB cable" most of them work only the way from A connector to micro B because of micro B pins 4 and 5 are connected together. The both way cable has directly connected 1-5 to 1-5 wires.

I tyied micro B - micro B about 10" as well but it didn't work because of "source" and "target" ends of it...

Finaly I used this one: https://www.secomp.cz/default.asp?cls=stoitem&stiid=10808

Thanks. I think that is what I need. I'm checking on Amazon and I don't see anything that looks like the cable you are describing. I'm looking for about 1.5 ft (.5 m) in length
