Creality CR-X/CR-X Pro Purge Slide

thingiverse

People have been asking for my CR-X Purge Slide and Profile for a while. This design has reduced my purge waste from an average of 200 grams per print down to less than 40 grams. The trick is purging only when a tool change is needed, not every layer like a Purge Block does. On High Contrast filaments, you can increase the purge from 50mm to 60-70mm to ensure a clean sharp transition. While it's not perfect, this Simplify3D Profile is functional. The only problem is that I have had to set the Hot End Temp manually at 215 degrees because S3D shuts off the temp when using the M109 S Wait commands. You can change this to your desired First Layer temp in the Slicer Profile. I have a BL Touch installed, so you must remove the G29 code from the Starting Script if you don't have Auto Leveling. After auto-leveling and solidifying the first layer, lower your hot end temp to whatever temperature you want for normal layers. The pictures show how to install the Purge Slide, which slips over the X Gantry Wheel axle on the Right Side Z Axis. Heat the short side of the mount before installation to avoid breaking it if using PLA or ABS. This design must fit tightly or the hot end may push off your Purge Slide! There will be approximately 3mm between the bed and the Purge Slide if installed correctly, with the Silicon Rubber strip level to the bed. You can use any 3mm thick Silicon Rubber from Amazon. The slot for the rubber is exactly 3.1mm. This design may work with Cura, but I don't use Cura and have no idea how to incorporate the Tool Change Script into their Starting Script. Special thanks to Vincent Fortin for his Purge Bucket, Jason Powell for his Purge Slide, and Nick Sanders for his S3D original scripts. This is a redesign of those designs, taking what I felt were the best parts along with a couple of mods by me. The Slide Shelf Ledge and Circular Mount provide stability, printability, and facilitate the blob! The Slide Shelf and Teflon Tape allow the blob to slide off easily at the next Tool Change. I have updated my Current Purge Slide FFF Profile from S3D along with my original Purge Block Profile in case you need to revert. You can find Silicon Rubber on Amazon: Silicone Sheet, 50A Durometer, Smooth Finish, No Backing, 3 mm Thickness, 2" Width, 36" Length, Red. Teflon Tape is also available on Amazon: Teflon Tape/PTFE Tape for Vacuum Sealer Machine, Hand and Impulse Sealers (3/4-inch x 33 Feet)-Suitable for FoodSaver, Seal A Meal, Weston, Cabella's and Many More.
