This text appears to be a guide on how to install and adjust the El Scorpion upgrade for a 3D printer, specifically a Folger Tech i3 2020. The writer provides detailed instructions on how to lower the hot-end to its lowest position possible, remove the fan and heat-sink, and adjust the nozzle height in relation to the fan ducts. They also offer suggestions on how to make adjustments with the proximity probe. Here are some key points from the guide: 1. Resolution: The suggested resolution for printing El Scorpion is 0.1mm. 2. Infill: The recommended infill density is between 60-100%. 3. Notes: * PLA is used for stiffness, and triangle supports should be set to 4 or 5mm. * The print should be done with the lower part upside down and the upper part upside down. * Support Z-distance should be at least 0.2mm to avoid difficulties in removing the support inside the fan duct. The guide also includes a series of steps for adjusting the nozzle height: 1. Remove the fan and heat-sink by pulling the screws at the bottom of the fan. 2. Cut the filament above the extruder, squeeze the extruder button thingy to release the filament, and pull the block away from the extruder. 3. Heat the hot-end to PLA-melting-temp, pull the filament from the throat, and cool the hot-end using a fan. 4. Loosen the set screw holding the throat to the block, lower it to its lowest point, and tighten the screw with an eye on the orientation of the heat-block (nozzle piece). 5. Without attaching the heat-sink and extruder-fan, put the screws back in the block and lock it into a height. 6. Check if the bottom of the nozzle is above or below the fan ducts and adjust the throat position as needed. 7. Wrap Kapton tape around the block attached to the nozzle, and put the screws back into the block with a couple turns into the motor. 8. Feed some filament through and get it into the throat and down to the nozzle. Pull the screws and put everything back together. The guide also offers suggestions for adjusting the proximity probe and making adjustments with the probe to ensure accurate measurements.
