# Enable the 'noisy' endstop feature, this should prevent the error on Z homing.

# Turned off thermal runaway on the bed heater (thermal runaway is still enabled on the hotend), this will prevent thermal runaway kicking in during a print.

I tested for several hours and did not run into any further firmware resets.  Please let me know if you encounter any. KE.

The Velleman K8200 is an opensource RepRap printer, also sold under the 3Drag name. This printer is connected to a Raspberry Pi with OctoPrint installed. To use, plug the 3d printer and Raspberry Pi into the mains and switch on, after a minute or so the Raspberry Pi will launch the webbased OctoPi control software. Connect your computer to the Makerspace wifi and point your web browser at http://192.168.1.20.

Upgrade Plans

Todo
  • Install RAMPS control board, Or possible a SKR1.3 32 bit board
  • Install new belts and tighten properly
  • Consider installing second Z lead screw and motor
  • Consider upgrading heated bed


Complete
  • New Easy Peelsy magnetic bed surface has been installed. Please do not use scrapers on it. Clean with Isopropanol before using.
  • Install new E3D hotend and direct drive Titan extruder for 1.75mm filament
  • Look at Z nut, currently has a lot of backlash. Complete, but Z flexible coupler needs replacing, new one is on order - Installed.
  • Install new power supply - This is the next upgrade required, current power supply cannot keep the bed up to temperature - ordered.
