Ender 3 BTT SKR Mini E3 V3 + CR-TOUCH + Sprite Pro + Dual-Z
My Ender 3 Pro has mostly drop in upgrades starting with the BTT SKR Mini E3 V3.0. Sprite Pro kit comes with new mounting plate with built in CR-TOUCH mount and probe offsets are based on this mount. Remaining are mostly my perferences and/or unique values that only apply to my specific Ender 3 Pro. * MPC instead of PID for hotend * Junction Deviation instead of Classic Jerk * Disabled S-Curve Acceleration (stresses CPU) * Probing Margin as close as possible to edge. * Double probing but at much faster feedrates and less movements. * 5x5 Bilinear ABL with restore after G28 and auto-heating. * LCD Bed Tramming and Assisted Tramming menus. * Fast Homing. * PLA/PETG/TPU temperature presets. * Nozzle Parking during filament changes. * Input Shaping * Auto Z-Calibration (G34) * Multistepping limited to 8 to prevent lost steps since underpowered boards jump to higher rates faster. * Probe offset wizard * Show Progress * Support long filenames * Babystepping with units in mm and combine with z probe offset. * Linear Advance. * Increase buffer sizes based on Octoprint recommendations. * Filament change menu and gcode. * Edge Stepping. Input shaping allows faster feedrates and acceleration than stock Enders but I'm currently fighting issues with dropped TX characters on serial port which leads to print quality issues when using Octoprint at higher print speed. 100 feedrate and 1000 accel is pretty stable. Remaining issues are likely a combination of SKR Mini E3 V3.0 being underpowered and EMI.
