Craftbot Plus SKR1.4 upgrade
Description
Some time ago my orginal CB-mainboard stopped working, good time to upgrade the printer with a mainboard working with opensource software! The craftbot will be improved a lot: faster, less noise, more features possible and no more closed software inside (never liked that). Now also on my (new) youtube channel: https://youtu.be/L61SB1pd0KA <strong>First, get some hardware:</strong> * BigTreeTech SKR1.4 (turbo) mainboard * 4x BigTreeTech TMC2209 stepperdrivers * BigTreeTech TFT3.5 v3.0 display * BigTreeTech BTT Writer v1.0 (optional, WIFI adapter programmer) * 35cm neopixel 12volt (60 leds/meter) RGB-ledstrip (we will replace the original white ledstrip) * stepdown XL6009e converter (we need this for the ledstrip) * 2x 120cm flatkabel 14wires (display: 3x5 wires, ledstrip: 3 wires) * 60cm flatkabel 2wires (for Y-end switch) * 2x 240cm wire (for fans) * 24v fan (to replace original 12v heaterfan) * 2x 24v fan (to replace original 12v objectfans) <strong>WIFI setup</strong> https://github.com/luc-github/ESP3D https://github.com/luc-github/ESP3D-WEBUI <strong>Craftbot hardware</strong> * 24Volt PSU * Extruder stepper: 17HS3001-20B * X,Y, Z steppers: 17HS3001-26B (or SL42S247A: 1.8deg.step DC2.5A) <strong>PID tuning</strong> You can find some info about it here: https://3dprintbeginner.com/hotend-and-heatbed-pid-tuning M303 E0 S245 C8 (extruder) M303 E-1 S90 C8 (bed) <strong>STL's</strong> Tthere are 3 versions of the SKR-plate: 1) default, only for the SKR board. 2) as 1 but with support for the stepdown converter (RGB led power) 3) as 2 but with extra support for the BigTreeTech Relay to shutdown the printer, I used it 2 days for testing and it burned out internally!!! (will not buy a new one ever, too risky!!)\ 4) as 2 but with extra support for a MosFet device, used for the extruder fan. Not ready yet, will be available in a few days.. <strong>Marlin</strong> I have added the complete Marlin-package with the current Crafbot configuration, so: just compile it and upload it in your SKR-board. <strong>Instructions</strong> Will follow asap, very busy with the design of the 3.5" display holder. This documentation is not ready yet.. 20-10-2020: status now: my Craftbot is running super with the SKR1.4 , a MosFet device and RGB leds. It prints every day very quiet and with good quality! I hope to finish things as soon as possible. If you want to start with rebuild, just go for it, if you need help, just contact me.
