The close proximity of the extruder and hot end means that retraction distances can be much less, allowing for easier management of stringing and other print artifacts that result from retraction. Thank you so much! It is great and works perfect. I only have a “issue” that the top surface is not that good. Any idea how to improve?

Easier to upgrade and maintain, since the hot end and extruder can be modified independently and use simpler designs. This design is generally effective, however there are a number of issues you can encounter after prolonged use:Before mounting the Sprite extruder, you need to cut the included PTFE tube to the proper length. You can use the extruder to measure the correct length as shown below. The tube should extend to the top of the Creality logo box. Once the tube is cut, ensure the opening is not obstructed or squished. You can use the point of the closed nippers to round out the tube. In this article, we will take a look at all of the extruders that are used on Creality printers, how they work, issues we have discovered, and whether we recommend upgrading them.

The last thing you need to know is that in Jyers the Z homing is done off the corner, contrasted with the official Creality firmware. Therefore, you need to mind the header of the Gcode created by Cura (or your slicer). Change the 'home all axes' setting to just home the X and Y axis (so you start from the corner. It’s a complete direct drive print head with good printing performance, capable of reaching up to 300C. And probably the most important feature is the easy upgrade path for Creality machines. You can easily install this on most Ender 3s in less than 30 minutes. On other machines, the time required for the upgrade should be similar and you will probably spend more time building a new firmware to accommodate the changes. No, it does not. Just received my kit. You'll need to connect the CR Touch directly to the controller board, by routing it together with the ribbon. Or buy the short cable from somewhere else. I will use the Sprite Pro Extruder for a longer period of time, and I will update the article if I find other issues. But right now, I think it’s a great direct drive extruder upgrade for any Creality printer.

The separate extruder means that the print head is lighter, allowing for faster printing and less likelihood of artifacts like "salmon skin" from inertia of the added weight. Here, we'll be saying, "Hey, motherboard? Ma'am? Wherever the nozzle stops, that's not it. Move the bed about a centimetre." The Sprite Pro Extruder body is also made from cast aluminum for more resistance to heat and maybe make it a bit stiffer. Filament path is correctly constrained, and paired with the short distance from the gears to the nozzle makes the Sprite Extruder a good performer when printing TPU filament. As you can see, the extrusion is very consistent and the results are excellent so there’s no denying that this extruder does a good job. There are some sections with inconsistent extrusion sections, but we’ll talk about those in another article. It’s not an issue generated by the extruder. Conclusions: Is the Creality Sprite Pro Extruder worth it? And I imaging that to be able to do this you need to be at a “Developer level” to understand how to do this correctly.

Inside the Titan extruder, the extruder gear is connected to the separate motor shaft through a gear system with a gear ratio of 3:1. Like the single-gear Bowden designs, the filament is driven on one side, while the other side is held by a freely rotating idler pulley. Below the gear, the filament path is fully enclosed, which is important to prevent jamming when printing with flexible filaments like TPU. The simpler design means they are typically less expensive and result in a lower total printer cost. The Sprite extruder-only upgrade requires a different e-step value, which is a setting that controls how far the printer needs to turn the extruder motor to extrude a certain amount of filament. You can configure the e-steps for the Sprite extruder using this process: Just for your information. I needed to adjust pressure advance so your settings don`t worked for my filament spool 🙂Navigate to Prepare » Move Axis and move the Extruder axis to confirm the extruder feeds filament properly.
