    Post processing script for Octoprint's @pause feature None of the existing pause at height scripts use the @pause feature for Octoprint to handle the pause and resume so I made a new script based off of the existing 'Pause at height' script to do that. You can give it a height in mm or layer number to pause after printing the layer specified. It does not add any commands like M or G for example. It only inserts an @pause into the gcode just before the layer height or layer number which tells Octoprint to handle the pause using Octoprint's 'PAUSE and RESUME scripts. By default Octoprint doesn't define any commands for the pause and resume scripts so you would need to put that in yourself in the Octoprint config under the PRINTER settings. This does not use any of Cura's pause and resume scripts as it is intended to use Octoprint for the pause and resume. 99.9% of the work for this script was already done and I didn't have to add much code so a big thank you for the developer of the original script. I removed a lot more code than added as this script only adds one @pause line to the gcode for each pause. If you combine this with the Telegram plugin for Octoprint, you can get notifications to your phone through Telegram when your printer pauses which is really handy so that I don't have to keep monitoring the printer at the right time. I have attached the PauseAtHeightOctoprint.py script. On Windows you can put the PauseAtHeightOctoprint.py script in your user data directory below for Cura 3.4 and restart Cura. I only tested this on Cura 3.4.1 but I suspect that this script would work for quite a few older versions of Cura too. There is an api version 2 specified in the script I created this from but I don't know when Cura starting supporting version 2 of the post processing scripts. Cura 3.4: %USERPROFILE%\AppData\Roaming\cura\3.4\scripts\ Other Cura versions configuration directories... https://github.com/Ultimaker/Cura/wiki/Cura-Preferences-and-Settings-Locations History: 1.3 (2018-08-23) Fixed a major bug where I put an incomplete version in the zip file. It was missing an import line for UM.Application. 1.2 (2018-08-20) Pulled in bug fixes from upstream PauseAtHeight script. See https://github.com/Ultimaker/Cura/commit/6740c2bee9a0732daf77224cd4ef34f0eb736364 1.1 (2018-08-12) Fixed script to use layer counts like Cura does. Cura starts counting layers as 1 even for negative layers like for the raft so we need this plugin to match the layer numbers as shown in Cura. 1.0 (2018-08-12) Initial release PauseAtHeightOctoprint-v1.3.zip

    Hello there, my name is Carsten and I use a an Ultimaker 2+ extended now for about one and a half years in Darmstadt, Germany. As I work for a pet-cremation company I print Urns in different sizes from 0.1 liter to 2 liter volumes. The material is extrudr Green-Tec Filament so the urns can be burried in the ground and then vanish. Urn and lids: See you!

    Hey guys, way more pics to follow, but here is the beggining of a WIP job based on my favourite front cover of a book ever 'Forest of Doom'. I thought I'd show you the techniques I used to print this really 3d printer unfriendly model and the small but important things you need to do it. I decided not to use PVA due to the reason that i dont need bottom details and can therefore sand it out easily, also print time is drastically less and no wait time is needed to see that actual model, so the time spent waiting for the PVA to melt is spent finishing the model which you would have to do regardless, I still believe that too much PVA is used in support and there needs to be a more efficient use of pve with some sort of dual system where only the support that actually touches the model is PVA and the rest is the same material as the model. The main difficulty was the fingers pointing down (or anything else small and long pointing down lol) as the support would only be from the fingertips which would no way be strong enough to support the entire arm before it joined up. Also print time is predicted to be around 2 days 2 hrs so it will be around 2days 6 or 7 hours by my experience. Still printing, 1 day remaining. Just the tree trunk done here so far....

    Hi all, to my opinion there is a mistake in the manual levelling routine, which only appears, when someone levels manually the UM3 and has to read the description in german. During the second levelling round, leveling the first point , one is supposed to ajust the hight with the (back) screw under the buildplate. - To read the whole text in german one has to scroll with the scrollwheel. (the english text is shorter, so it doesn become obvious there ) - the printbed hight is (in this step only) sensitive to the scrollwheel! - That means , if a user reads what to do, he changes the hight of the printbed, which he had set in the first round. This leads to a wrong levelling. Am I wrong? Best - Yvonne (Before anyone asks ... of course I work with the latest firmware. And I was able to check that on many different UM3s)
