Hallo zusammen,

ich bin gerade dabei, OctoPrint mit meinem alten CAT S41 OctoPrint zum Laufen zu bringen.

Da ich noch gar keine Erfahrungen mit OctoPrint habe, muss ich hier gleich mal ein Thema darüber aufmachen.

Und die ersten Fragen:

Wie auf den Bildern zu sehen, benötige ich diese Werte, um das Ganze am Laufen zu bekommen.
Kann jemand helfen?

Hello everyone,

I’m in the process of getting OctoPrint to work with my old CAT S41 OctoPrint.

Since I haven’t had any experience with OctoPrint yet, I have to open a topic about it right away.

And the first questions:

As you can see in the pictures, I need these values to get the whole thing up and running.
Can someone help?

You are able to see the maximum feedrate in the machinesettings M503 of your machine.
Would be nice if you share these so i could compare to 2.0 :wink:

M203 [E<units/s>] [T] [X<units/s>] [Y<units/s>] [Z<units/s>] is your max feedrate.

About the inverse, i dont know, but you could simply test it by jogging the axis in octoprint after setting up.

To your second picture, i could imagine that the standard extrusion length is the extrudes length for priming the nozzle, i guess this setting is not really needed for octorpint.

Danke, für den Tipp.
Ich bin mir nicht sicher, ob ich das Ergebnis richtig auswerten kann.

Thanks for the tip.
I’m not sure if I can evaluate the result correctly.

Maximum feedrates (units/s):
Recv: echo: M203 X350.00 Y350.00 Z10.00 E80.00 means mm/s.
Octoprint wants your units in mm/min so you have to multiplicate with 60.
X, Y and Z are your axis and E is your extruder.

Vielen Dank …
Dann müsste das hier passen…?

Best Thanks
Then this should fit here…?

@xchrisd

Gibt es eine Möglichkeit der Fernwartung von OctoPrint, ohne diese zahlungspflichtigen Plugins?
Das müsste doch auch via Fritz!Box zu machen sein, oder?

Is there a way to remotely maintain OctoPrint without these paid plugins?
That should also be possible via Fritz!Box, right?

Yes.

Not sure what you mean. Never saw a paid plugin for octoprint.
I look at my octoprint via dynamic dns which is set in my router.

I use no-ip for free hosting my octoprint.

There are many forum threads about octoprint, have fun at reading :wink:

Use the search for more :+1:

Ich würde es aus Sicherheitsgründen vermeiden, den Drucker oder den Raspi direkt ins Internet zu lassen.

Richte Dir einen VPN-Zugang in der Fritzbox (oder auf dem Octoprint-Raspi selbst, z.B. indem Du Wireguard da drauf installierst) ein und besorg Dir einen dynamischen DNS-Zugang, den Du in der Fritzbox verknüpfst - ich verwende hier https://ddnss.de dafür. Dann brauchst Du nur noch einen Wireguard-Client auf dem Gerät / den Geräten, mit denen Du von außen zugreifen willst und kannst darüber dann in Dein privates Netzwerk und auf den Drucker zugreifen. Alle anderen können da dann nicht rein, es kann Dir also nicht irgendein Ganove Ärger bereiten.

For security reasons, I would not let the printer or the Raspi directly access the Internet.

Set up a VPN access in your router (or on the Octoprint Raspi itself, e.g. by installing Wireguard on it) and get a dynamic DNS access that you link in the router - I use https://ddnss.de for this. Then you only need a Wireguard client on the device(s) you want to access from outside and can then use it to access your private network and the printer. All others can’t get in, so no hackers can cause you trouble.
