-
In Configuration.h scroll to line 417 and set the TEMP_SENSOR_BED value to "1".
-
-
-
In the Arduino IDE go to Sketch -> Include Library -> Manage Libraries...
-
Search for TMCStepper and install the latest version.
-
-
-
Replace A4988 with TMC2208 depending on where you have the drivers installed on the board.
-
-
-
Scroll to line 1067 (File -> Preferences -> display line numbers) and set as shown if that axis has a TMC2208 driver installed:
-
INVERT_X_DIR true
-
INVERT_Y_DIR true
-
INVERT_Z_DIR false
-
INVERT_E0_DIR true
-
INVERT_E1_DIR true
-
-
-
Once open, click INSTALL.
-
Once done, you should get a success message, click OK and close the programme.
-
-
-
Connect the AXIS to your PC via the usb cable.
-
On windows you can open device manager by right clicking the windows icon. The Printer should show up as CH340, note the COM port number. In this case COM4.
-
-
-
Go to tools and set the port to the COM number that is for the AXIS.
-
Make sure that the board and processor are both set to Mega 2560.
-
Finally upload the firmware to the AXIS.
-
-
-
Once the firmware has completed uploading, connect the AXIS to the mains.
-
When powered up, check that the electronics fan and the hotend fan are both spinning.
-
-
-
Set the port to the same COM number.
-
Set the baudrate to 250000.
-
Finally, hit connect.
-
-
-
Send an M119 command to check the status of the endstops.
-
They should all report back "open".
-
Manually push down the X-Axis endstop, and whilst keeping it pushed, send the M119 command again. It should report back as "triggered".
-
Repeat this for the Y-axis endstop also.
-
-
-
Whilst holding a metal object under the probe (a red light should shine) send the M119 command.
-
Pronterface should return: z_min: TRIGGERED.
-
-
-
X-Axis: Pressing the left arrow will move the bed to the right, and vice versa.
-
Y-Axis: Pressing the down arrow will move the Hotend towards the front of the printer and vice versa.
-
Z-Axis: Pressing the up arrow on the Z-axis will move the gantry up and vice versa.
-
-
-
If an axis from the previous step moves in the wrong direction power off your printer.
-
In the aruino IDE go to the "configuration.h" tab.
-
Scroll down to lines 1066-1069. (Go to File -> Preferences and check "Display line numbers")
-
#define INVERT_X_DIR true
-
Change false to true to switch the motors direction depending on the problem axis (X, Y or Z).
-
Re-upload the firmware.
-
Continue from the previous step.
-
-
-
Home X - The platform will move all the way to the left until the end-stop on the base is triggered.
-
Home Y - The hotend will move towards the z-pillar until the eccentric guide triggers the end-stop on the gantry.
-
Lower the Z axis - Lower the gantry incrementally to check the that the nozzle is aligned with the top right corner of the print surface, this is your (300,200) co-ordinate.
-
The hotend nozzle should be above the top right corner of the print surface.
-
-
-
Click "motors off" in Pronterface. Manually move the tool carriage so that the probe is hovering over the centre of the platform.
-
Lower the gantry by hand so that the nozzle comes close to the print surface. Once close enough the red light on the probe should come on before the nozzle hits the print surface.
-
-
-
After successfully homing with G28 run the G29 autolevel command.
-
Once a mesh is generated send M500 to save it to the printers memory.
-
-
-
Send G28 to home all axes.
-
Send "M420 S0" to turn off the auto-levelling.
-
Send M114 to report the nozzle position, the Z-axis should be at 0
-
-
-
Place a folded piece of paper between the nozzle and print surface. Lower the Z axis in 0.1mm increments until the nozzle grips onto the paper.
-
Send the M114 command again to report the Z-axis position.
-
The amount that you lowered the z axis by is your Z-offset.
-
Enter M206 Z(value)
-
Send an M500 command to save it to the printers memory.
-
-
-
Take your PLA filament and cut a sharp end.
-
Place the spool onto the holder and feed the filament in through the extruder like shown, until it hits the bottom of the hotend.
-
-
-
Make sure that the 30mm fan is spinning, this fan should always be one, powering your hotend without this fan on will cause damage.
-
Raise the gantry up by between 60-80mm
-
Set the hotend to 200 degrees and press set to begin heating.
-
-
-
Once the hotend has reached 200 degrees celcius, you can begin extruding.
-
Press extrude to extrude the filament.
-
Check the motion of the drive gear, it should turn anti-clockwise in order to feed filament into the hotend.
-
You should have a nice, straight stream of filament flowing from the nozzle.
-
-
-
First make sure that the beds power supply is plugged in and switched on at the mains.
-
Set the bed temperature to 60 degrees Celsius.
-
Press set to power on the bed.
-
A red LED on the back of the heated bed should shine to indicate heating.
-
Let the bed get up to 60 degrees before shutting it off.
