The text appears to be a guide for calibrating and adjusting a 3D printer, specifically a delta printer. The guide covers various steps and techniques for ensuring the printer prints accurately and efficiently. Here are some key points from the guide: 1. **Calibrate Extruder**: Measure how far 50mm of filament goes and call this value A. Calculate 50/A to determine if too much or too little filament is being used. 2. **Adjust E Steps Per Unit**: Multiply the calculated value by the E steps/mm from configuration.h, then change the E steps value and reupload. Repeat until the extruder feeds exactly 50mm of filament when requested. 3. **Check Extruder Speed**: Test the maximum speed of the extruder by sending M302 and trying different speeds in increments (100, 200, 300 mm/min) until the motor stalls. Then, increase the current a bit and try again. The value derived is the fastest the extruder can move. 4. **Convert to mm/s**: Divide the maximum speed by 60 to get mm/s, which is what most slicers use. Use this value (or approximately 10% less) as the retraction speed in your slicer. Additionally, the guide mentions: * **Bowden Tube Setup**: Cut ends of the bowden tube at exactly 90 degrees cleanly and push them into the bowden couplers on the extruder and hot end. Ensure there is no play in the tube to prevent blobs/strings. * **Printing Initial Layer**: Change the gap between nozzle and bed by sending M206 commands, using a z-offset setting in your slicer, or babystepping. Record the amount moved and use it as the z-offset for future prints. The guide also mentions modifying and improving on the machine in any way desired and incorporating the best mods into the original.
