  1. This software is free, was made by people working in their free time, and the source code is open and available to anyone who wants to take a look and help improve it, so please keep that in mind. Second, your problem is almost certainly due to arcs being disabled in your firmware. I'm guessing you upgraded your printer with a bed leveler, and flashed new firmware for that. I see lots of these firmware forks, and most of them have arcs disabled for creality printers due to limited program space. It's very easy to check to see if arcs are enabled within your printer's firmware by sending the following command to your printer (easiest way is with the OctoPrint terminal) and see how it responds: G2 If it says 'unknown command' or something similar to that, arcs are disabled and you cannot print any gcode that contains arc commands. If it says, "Invalid Parameters", arcs are enabled and the fault is likely with ArcWelder itslef.

  2. That means they are enabled, so you should be good to go! If you are using OctoPrint, that will disconnect your printer, but that's expected, and causes no harm. Just reconnect and know that empty G2/G3 commands will NOT be generated by ArcWelder (unless there is a bug, lol). Just open the file and search for G2/G3 commands and see if there are any. If you are using OctoPrint, you might want to try out the beta version of the Arc Welder OctoPrint plugin (you can disable it later when you are comfortable). It has a firmware checker, will give you a ton of useful statistics you can use to see what ArcWelder is doing, and has detailed help files explaining all of the settings. That might be useful for you until you are comfortable enough with ArcWelder to switch back to the cura plugin, which is a lot faster and more convenient in many cases. If you are interested, see these instructions and leave any feedback (please do) here. Also, FYI, the new version will not even attempt to re-weld any files that were previously welded, so nothing will happen if you are welding in Cura.

  3. Hi, Often getting started is the most difficult part of any process. A good start sets you up for success and saves you time and energy that could be spent elsewhere. It also allows you to get more out of your product and enjoy the benefits faster. That is why we have an onboarding course ready for: Ultimaker S5 Pro Bundle, Ultimaker S5, Ultimaker S3 Ultimaker 2+ Connect. They're ready for you on the Ultimaker Academy platform! Bonus tip: Entirely new to 3D printing? You may run into a lot of new terminology. Make sure you fully understand what everyone is on about and follow this course about FFF terminology!

  4. Please tone down, or this will be the last time I will respond to you. It is possible that your printer uses a firmware version that does not have support for printing arc movements.

  5. The biggest implication being that Ultimaker pays them to develop software for Ultimaker printers. The fact that it can also be used for other printers is a bonus. But any feature that does not directly benefit Ultimaker printers either has to come from community members like @burtoogle or me, or from printer manufacturers. The Ultimaker employees still take time to check and include these contributions, but at times they also have to reject features because it would take the project too far from what Ultimaker needs or it would take too much time in the future to maintain the feature in the codebase. My contributions have been mainly in the frontend, not in CuraEngine. Some of the changes you need could be implemented by postprocessing the gcode that CuraEngine creates, which can be done with a plugin in Cura. CuraEngine does not have a plugin-system, only the frontend does. For example, I have written Blackbelt Cura (which is still for FFF printers, but slices at an angle) completely as a set of plugins. No, not really. As far as I know.

  6. I think that the goal is different. In the case of Cura the goal is to reduce the seam, by going a little bit further it helps to reduce the scar and just the size of the nozzle is enought ( 0.4 - 0.6 mm) I don't use Simplify but in the case of PrusaSlicer you have the same type of setting. In this case the main goal is to reduce oozing and stringing. The distance is much more longer and in PrusaSlicer they also integrate in this extansion a certain percentage of the filament retract. On my point of view this solution is better than the Cura option. Perhaps a futur enhancement.

  7. Was für ein Spalt zum unterem Ring? Der Coupler geht mit dem dicken Ende nicht ganz runter zum Steel Coupler. Sollte bei dem alten auch so gewesen sein. Wenn vorher das Filament zwischen den Heizblock und Coupler gewesen ist, musst du alles auseinander bauen und reinigen/entfernen. Einfach einen neuen oben rauf wird nicht helfen. edit: Es kann auch sein dass dein Hotend oder die Düse verstopft ist. Vieleicht druckst du auch zu schnell und gleichzeitig zu kalt. Wenn du deine Einstellungen posten könntest, würde es etwas helfen. Wie auch immer, sobald Filament zwischen dem Coupler und hotend ist, wird das problem immer wieder kommen wenn du nicht alles ausbaust und sauber machst.

  8. I think the retraction occurs while the nozzle is still in contact with the part. Moving 30mm takes a bit of time so you get a deformed area. You could try setting the Initial Retraction distance to 2 or 3 or even 0. It would end much quicker and the print head would go to the location without spending so much time in contact with the print. You can also try using Pause at Height instead. It's slightly different but I like it for filament changes because I can set the stepper disarm timeout to 1800 seconds (30 minutes) which I find to be much better than the 2 minutes that it usually is. I don't use the initial retraction at all. On the restart I just pull about 3mm of filament back after pushing enough by hand to change colors. That keeps it from leaving a blob on the restart.

  9. Testing junction deviation with linear advance and arc welder: First test: linear advance + junction deviation + arc welder + "G90 influences extruder" on. This caused the extruder to vibrate a lot on corners, with the XY movement almost completely stopping there. Gave up the print on the first layer afraid it could damage de extruder. Curved motion was smooth on the XY axis. Second test: linear advance + junction deviation + arc welder + "G90 influences extruder" off. Same. Maybe LA is causing the issue. Third test: junction deviation + arc welder + "G90 influences extruder" on. No vibration on the extruder. Overall smooth movement, but the printer still stops for a second on some corners leaving a melted spot (not a blob of filament). Forth test: classic jerk + linear advance + arc welder + "G90 influences extruder" on No vibration on the extruder. Overall smooth movement. No stopping on corners. It seams the problem was JD all along. Unfortunately arc welder does not help "fixing" junction deviation.

  10. It is 100% a visualization problem. If you have OctoPrint installed anywhere, I highly recommend using 'PrettyGcodeViewer' to look at these files. It uses a port of Marlin 2.0's arc interpolation algorithm, so you can be sure what you are see is what you will get. Barring that, Simplify 3d is the 2nd best viewer, though it also renders arcs with a relatively low resolution (think scad's facet setting if it is low). It is still very good. NCViewer.com is SO SO close to being great, but it does need a few tweaks, like ignoring some gcodes (it treats progress gcodes like arcs for some reason) and increasing the number of facets per arc.

  11. Thanks for all your help! I think you are right that the Alpha version was better, this makes me think its down to line heights and thicknesses and if they add up to a height thats divisible by the height. For example if the change is at 10mm and you have the layer height at 0.1 then it would be at the right height when it hits this change, But if you had the layer height at 0,15 then it would not be correct and would cause this problem more. This is just a guess and ive yet to test it. Will see if i get the chance...

  12. Working model of wind turbine for O scale model railroad. Stepper motor in base, vertical shaft, gears on top. The base uses the 'fuzzy skin' function of Cura. First time I have used that for a 'production' piece.
