Slicers will often allow one to configure "Start G-Code" and "EndG-Code" sequences. It is often convenient to define custom macros inthe Klipper config file instead - such as: [gcode_macro START_PRINT]and [gcode_macro END_PRINT]. Then one can just run START_PRINT andEND_PRINT in the slicer's configuration. Defining these actions in theKlipper configuration may make it easier to tweak the printer's startand end steps as changes do not require re-slicing.
The maximum speed and acceleration of retraction moves are controlledin Klipper by the max_extrude_only_velocity andmax_extrude_only_accel config settings. These settings have adefault value that should work well on many printers. However, if onehas configured a large retraction in the slicer (eg, 5mm or greater)then one may find they limit the desired speed of retractions.
Specifically, if the slicer dramatically changes the extrusion ratebetween moves then Klipper will perform deceleration and accelerationbetween moves. This is likely to make blobbing worse, not better.
Some slicers advertise an "advanced extruder pressure" capability. Itis recommended to keep these options disabled when using Klipper asthey are likely to result in poor quality prints. Consider usingKlipper's pressure advance instead.
Specifically, these slicer settings can instruct the firmware to makewild changes to the extrusion rate in the hope that the firmware willapproximate those requests and the printer will roughly obtain adesirable extruder pressure. Klipper, however, utilizes precisekinematic calculations and timing. When Klipper is commanded to makesignificant changes to the extrusion rate it will plan out thecorresponding changes to velocity, acceleration, and extrudermovement - which is not the slicer's intent. The slicer may evencommand excessive extrusion rates to the point that it triggersKlipper's maximum extrusion cross-section check.
Also note that these slicers will insert their own heating codes whencertain conditions are not met. In Cura, the existence of thematerial_bed_temperature_layer_0 and material_print_temperature_layer_0variables is enough to mitigate this. In slic3r derivatives,you would use:
Pair it up with Cura, and you open up a world of new possibilities for your 3D printing workflow. Cura is one of the most widely used and popular 3D printer slicers with top-notch features that help you achieve high-quality 3D prints.
The benefits of Cura slicer lie in its user-friendly nature and open-source development. It supports numerous 3D printers, is easy to use, and Ultimaker constantly keeps Cura up-to-date with the latest features.
I just got started with klipper on my ender3 and it's awesome. But I often read about SuperSlicer now and wonder, if this slicer is more suitable for klipper printers. Right now I use Cura with the KlipperSettingsPlugin
as the filaments I use have a little bit different structures and diameter-tolerances do a calibrating (measure and extrude 100mm) with each filament-type and as I get different results I could change the feedrate in slicer or at the printer or I can change the rotation_distance
worthwhile pursuit to share slicer profiles for the MP3DP. Of course some details will be off but if we can see results and cross reference speeds, we might be able to get some data that will let us optimize our own printers. This is lime the kind of leverege that Prusa gets within the slicer to get high quality printing when you use their printers.
Orca Slicer has an easy-to-use but powerful interface and innovative features. Ideal for beginner and advanced 3D printer makers, Orca Slicer has made quite a splash. There are many other slicers, like PrusaSlicer, Bambu Studio, UltiMaker Cura, and Slic3r, so what makes Orca Slicer unique? How do you set it up? Is it the right slicer for you?
i am using the new beta cura 5.5.0 just come out it as the sv07 klipper on it work very well, also i asked sovol when the new version of there software is coming out they said very soon still working on it
If you want Cura to be less skewed to a single brand; Please contribute more. We would *love* to get more contributions that fix other things. But as it stands, the developers are paid for by Ultimaker, which also means that the strategy of the company is what drives the new features of the slicer.
The slicer environment looks really interesting, but unfortunately I don't see a profile for my Sovol SV04 printer with idex anywhere. I don't really want to set up the profile from the very beginning, because there are slightly different parameters thanks to the two extruders. Is there somewhere to download this profile?
I like this slicer but wish we could override the spacing error indicating prints are too close together when print sequence is "by object". For instance, if I'm trying to print one very thin object and then a separate one immediately adjacent so they they fuse together (printing a butterfly outline and then color inserts on my single extruder voron printer) I get an error ".stl is too close to others and collisions may occur" that I can not override meaning I have to use a different slicer to accomplish what I want to do.
This is needed to have Chancel Objects in Octoprint or exclude_object in Klipper working and both are killer tools in a production. Full build plate of 100 parts. 1 is having print issues - just exclude it.
If that is something you will bring in your Printer Firmware - maybe. But please add the feature into the slicer.
This tutorial is primarily concerned with step 1 as well as our PRINT_START macro. We will be using SuperSlicer for the slicer and a Voron 2.4 for the printer side of things (though any Voron will do).
Also note that the third line contains a call to PRINT_START, along with several values after PRINT_START. The options after PRINT_START are parameters and these allow for passing information from the slicer into the PRINT_START macro on the printer itself.
Before we see how the two are interrelated, where do these values come from? Lets take the last one for example, CHAMBER. CHAMBER is the name of the parameter, and the value will be taken from the slicer option, located between the square brackets. For CHAMBER, that would be [chamber_temperature], and the value itself comes from the chamber_temperature parameter in the slicer. To find where this parameter is set in the slicer, search for this value using the magnifying glass option below the Print Settings tab. Searching shows us that it is on in the Filament Settings tab, under Filament, and then Chamber. Hovering over the text box where we can type in a value shows the parameter name, chamber_temperature, in a tool tip, along with more information as to what the parameter does, its default value, and so on.
Most of us, when first starting out, used these types of macros and hoped for the best. In many cases, things worked out fine and we actually had the printer bed heat up, the hot end heat up, and the print started. But how did the printer know what temperatures to set for the bed and hot end? To understand that, we need to look a bit closer at the gcode being generated from the slicer.
THIS is how we were able to be successful in printing things without having to manually set bed temps, hot end temps, and so on, because the slicer inserted the appropriate calls for us to ensure the heating happened.
Inside the curly brace is a variable, but where did this variable come from? I am glad you asked! It came from the slicer, and the custom start G-code we set up earlier (we saw in our exported gcode in both examples the parameter names after PRINT_START).
Before we can actually use those variables however, we have to extract them from the parameters passed into the PRINT_START macro. These parameters are held in a collection that klipper maintains, called params. Notice at the beginning of our new macro we see another new notation, also in curly braces. One example is shown below:
Notice the discrepancy between what the slicer sent in, and what the PRINT_START macro is looking for. Specifically, the slicer sent in EXTRUDER, but we are looking for params.EXTRUDER_TEMP, which does not exist! This will cause an error to be thrown, since we are wanting to set a variable in our PRINT_START to the value of that parameter. The fix of course would be to make sure what is getting passed from the slicer matches what we are looking for in our PRINT_START macro.
This syntax would attempt to look for a parameter named SHOE_SIZE and, if it exists, use that value for MY_SHOE_SIZE, but if that parameter was NOT specified in our slicer, MY_SHOE_SIZE would be set to a value of 11, the default! In both cases it would be set to an integer.
Use this with caution though. It is not a good idea to set a default BED or EXTRUDER temp using a default like this. In those cases it is better for the PRINT_START call error out when we did not pass that in from the slicer.
Finally, note that you are not limited to only passing things that exist as parameters from the slicer. If you wanted to pass in custom variables, just add them to the custom start gcode section, and then pull them out in PRINT_START, like this:
RatOS comes with START_PRINT and END_PRINT macros that you can call directly from your slicers. This way the printer knows how to start a print, and you can there easily switch between slicers without worrying if you changed anything in another slicer.The g-code for these macros are found in config/printers/[PRINTER_NAME]/macros.cfg
For KP3S Pro V2 and KLP1 users, it is better to switch to other slicers like Orca Slier or PrusaSlicer to get best or better printing performance. Orca Slicer is the first option for our Klipper models.
Although setting in the PrusaSlicer is much easier than it is in the UltiMaker Cura, but to monitor the remote printing in it is not so convenient as Cura and Orca Slicer do. You need to click to the gear icon on the right side of the printer name. Then a window will popup, click yes, the slicer will open the Klipper dashboard in your browser.
