Re: OctoPi, OctoPrint and MK2

@ronald.k

At least you have to define your printer profile and mark it as favorite, then define your connection parameters and (could be helpful) some temperature sets to preheat your printer.

But, you're right, no additional GCODE ! It works like a charms out of box.

Re: OctoPi, OctoPrint and MK2

My OctoPi has a copy of cura in it. Is there a cura profile for the i3 mk2?

Re: OctoPi, OctoPrint and MK2

Hi,

for anyybody having the temptation to make a port redirection to access your OctoPi box remotely (which I discourage for security reason), I recommend instead to have a look at remot3.it instead, based on weased protocol.

Have a look at the setup here: http://forum.weaved.com/t/how-to-get-started-with-remot3-it-for-pi/1029/5

remot3.it will work as a reverse proxy instead, you will not have to open a port on your home router, the traffic will be encapsulated in https and you keep control of the protocol you want to provide through weased agent configuration on your OctoPi box.

It's not as secured as no remote access, but it's better than a simple port natting, leaving only the poor OctoPi security layer.

I'm like Jon Snow, I know nothing.

Re: OctoPi, OctoPrint and MK2

Hi guys i just put my kit together and so on. In other words a total 3D printing newbie. Id like to use octopi to print to get rid of the "hazzle" of moving the SD card around but I have some questions that might be a bit dumb but I'm to worried about ruining the heatbed not to ask them.
So to start of i figure I'd just use slicer to get the gcode and then load that to the octopi mostly because I do find it to be a rather easy to understand software at least so far.
For the serial connection it seems to work with the auto settings and if not the baudrate should be 115200 from what I've managed to gather.
Or should i change some of those intervals (temperature, timeouts etc)?

What i really wonder about is what the printer profile should be. This is what I have so far:
I guess the general tab as long as the identifier is right could be what ever..

for the print bed and build volumes tab i just put in what i found on the prusa web page but are these right or have i mixed them up (I'm thinking xyz)?

I have no idea for the Axes tab. what is this?

Well the hotend & extruder tab should be right? since the mk2s ships with a 0.4 nozzle and i don't have the rather awesome multi material upgrade kit.

for the temperature presets should i change this to what the printer use when i choose preheat on the LCD?

also I do not intend to access octoprint from the internet since the security is some what iffy 😉 although I have forced SSL anyway

Id appreciate any help you guys can give me on this!

Re: OctoPi, OctoPrint and MK2

Guys,

It seems the default acceleration settings in Octoprint are wrong, what are you all using?

Edit: Managed to get them via the M503 command. 9000, 9000, 500, 10000

Re: OctoPi, OctoPrint and MK2

There is no acceleration rates, Do you mean the speeds for the manual control (as shown in a screenshot above), they DO NOT influence sliced gcodes!

Re: OctoPi, OctoPrint and MK2

Hi,

my IP cam died so I bought a cheap Edimax ic-3115w. I thought I put the needed params here to get it to work with Octoprint.

Image path for timelapse and telegram:

?account=user&password=pw

Video path:
http://user:pwd@192.168.0,45:80/mjpg/video.mjpg


/webcam//mjpg/video.mjpg


backend webcam
reqrep ^([^\ :]*)\ /webcam/(.*) \1\ /\2
server webcam1 192.168.0.45:80/mjpg/video.mjpg
reqadd Authorization:\ Basic\ TOKENSEEBELOW

To get the auth token use this on the Raspi:
echo -n user:pwd | openssl enc -a

That should also help with other cams which need the user/pw NOT as parameter.

Re: OctoPi, OctoPrint and MK2

Hello everybody,

i've got a few question:

this week i will order my original mk2s kit , with the multi material upgrade.

currently i'm using a anet a8 printer with a octoprint setup on a pi3.

everything works ok, local acces , remote acces (outside my local network) with wan and acces with ddns server.

camera works, got cura and slic3r installed as a slicer on the pi. and the shared folder works.

when i receive the mk2s i can connect it with my pi, and generate g codes with the onboard slicers or on the laptop with s3d.

but when the multi material upgrade arrives....will there be a upgrade available for slic3r..... just looked at the manuals and instruction menu on the

prusa site, there they talk about the Multi Material post processor , where can i find this....? and could that be installd on the pi ?

when i generate a gcode with slic3r with the multi media processor, will octoprint accept this gcode....?

thnxs in advance 😉

Currently, a post-processor is used to generate the code necessary for tool change; this post-processor may not be able to run on the Pi. However, I have a feeling that the post-processor will (sooner or later) be incorporated into Slic3r.

The code generated by the post-processor is standard GCode; however OctoPrint does have some difficulty in interpreting the GCode (especially so in the GCode Viewer tab) which I believe is down to that software (and not the post-processor) as the printer manages to understand the code generated. It may be better when/if the PP is included within Slic3r.

Re: OctoPi, OctoPrint and MK2

The limitations of the Cura implementation in OctoPi has caused me to turn off GCODE viewer and use "normal" Slic3r Prusa Edition or Simplify 3D and merely use OctoPrint as a "G-CODE processor". The nice thing is that since Slic3r PE has OctoPrint API support, I can send it directly to the printer already sliced and prepared as GCODE for printing. I also have my Windows machine setup to send stuff from Fusion 360 direct to Slic3r which allows for a simple workflow. I know that OctoPrint has Slic3r support as an option, but I've found that the workflow I use was already efficient enough to not worry about any slicing or configuration issues in OctoPrint.

Re: OctoPi, OctoPrint and MK2

Quick question: does octopi disable some lcd functions when it is printing?

(I use repetier server and while repetier server is printing I can not "unload filament" or "pause print" via the printers lcd. I have to use a computer to pause the print or change filament.)

I am no expert, but I can say is the same happens with my setup. So, I would say this is normal. I have found that you cannot cancel a print either. I have only been able to do this through the octopi web page.

Re: OctoPi, OctoPrint and MK2

It depends if you are printing from SD card or Octopi Memory. You have an option to print from either through the octoprint interface. You still get all the "Tune" and "Support" menu options when printing from octoprint from either source. This includes changing filament.

Re: OctoPi, OctoPrint and MK2

I just installed OctoPrint 1.3.5 on a Rpi2 running Ubuntu Mate with Node-Red, MQTT and some other stuff (WiFi) but without cam. Everything is in a local network.

I really like this app, together with the MQTT plugin that you have to install. This opens up quite a few possibilities related to IoT.

There is still some work to be done in term of communication to the printer (MK2S running 3.0.12). 115200 is just too slow if you want to upload files to the printer SD card. Then, you get a list of files with the old (very old) 8.3 DOS format.
Back to Windows 3.1, 25 years ago...Happy Birthday!
Better keep the files on the RPi.

The terminal tab allows you to see the different commands sent to the printer. Something you can learn from that.

So far so good and thanks to the developers.

Re: OctoPi, OctoPrint and MK2

I have a few questions about OctoPi. Would there be a noticeable drop in performance if I used a Pi Zero W vs a Pi 3 to slice the stls? Would the difference be because of the amount of RAM or because the difference in the power of the CPU?

Re: OctoPi, OctoPrint and MK2

So how do I get octoprint to do that little starter/test strip at bottom left corner of the pad? If I run a print from the sd the old way, it prints that little strip. But if I load and print from octoprint, it doesn't do that line for some reason. It's a nice feature because it ensures that the printer is extruding and the print is more likely to succeed.

the 8.3 file naming is annoying, but I think it has something to do with using the FAT filesystem still, even though the SD card is formatted with fat32 and it does support long file names.... So it has something to do with octopriint still I suspect.

Re: OctoPi, OctoPrint and MK2

Found that it was my settings in slicr3 got messed up some time. The timing was impeccable since it started happening the same time I started used octoprint.
