3D printer 2
edsard boelen, 1 may 2021
it has been 10 years ago since I built my first 3d printer. In the meantime, the printers have improved quite a lot and the price also dropped. They can be tuned much better now. It is also fun for the kids to learn more about 3d and machines and motors.
construction
The printer comes partially assembled, construction is done in about an hour.
Octopi controller and camera
Lights and power
The power supply of the ender is 24V. It can handle a raspberry pi just fine. Also a led strip on the top bar will give it enough light for the camera.
Auto leveling
There are inductive proximity sensors. These can be attached to the Z-axis home input. But the firmware needs to be updated...
For the crealty ender 3 v2 you can download the firmware and update the configuration.h with the correct parameters.
#define FIX_MOUNTED_PROBE
#define Z_SAFE_HOMING_X_POINT 15 // X point for Z homing
#define Z_SAFE_HOMING_Y_POINT 15
#define NOZZLE_TO_PROBE_OFFSET { -43, 4, 0 }

for the auto level to run at the start of each print, add the following G-code: G29
