Anet-A8 Auto_Nozzle_Brush with worn-out toothbrush

thingiverse

It appears you have provided a configuration file for your 3D printer, specifically for the Anet A8 model with a Skynet-3D v2.3.2 firmware and an auto-leveling system using a rear-center mounted tubular proximity Z-level probe. This configuration includes settings for Cura 15.04.6 and modifications for three-point Z-level adjusting. Here are some key points from the provided configuration: 1. **Start G-Code**: The start of the print job is defined with commands that set metric values, move to absolute positioning, turn off the extruder fan, move to minimum endstops for X and Y axes, and then set temperature for the hotend and heated bed. 2. **Customizing for Nozzle Brush**: This section contains custom G-code that seems to be specifically designed for preparing the nozzle before printing. It involves moving the head around in a series of back-and-forth movements with the extruder turned on to deposit filament, followed by retracting it. This process is likely aimed at ensuring good adhesion between the first layer and the print bed. 3. **End G-Code**: The end of the print job includes commands that turn off the extruder heater, move the hotend up and retract some more filament, move the Z axis up slightly, reduce filament pressure if an extension is present (T0), turn off the steppers, and finally return to home position. ### Steps to Implement in Cura: 1. **Firmware**: Ensure you're running Skynet (Marlin) firmware on your printer. 2. **Cura Settings**: - Go to `Slicer > Configuration > Print > G-Codes > Start G-Code & End G-Code`. - Paste the provided start and end G-code into their respective fields in Cura. 3. **Script Tab**: - Ensure that you've blanked out the Repetier's "Scripts" tab, as mentioned. ### Notes: - The configuration includes specific commands for customizing the nozzle before printing (`Custumizing For Nozzle Brush` section). This is unique to your setup and aims at preparing the nozzle by depositing a small amount of filament in various patterns. - The end G-code includes commands to retract filament after the print, which can help prevent oozing or unwanted extrusion when moving the hotend up. - Always verify that the firmware on your printer matches the requirements specified in the configuration file for optimal performance.
