Initial Startup Checks

※Verify Temperature

Start by verifying that temperatures are being properly reported. Navigate to the Mainsail temperature graph.

Verify that the nozzle and bed temperatures are displaying correctly and are not increasing. If the temperatures continue to rise, disconnect the printer from power. If the temperatures are inaccurate, the issue may be due to wiring or hardware faults.

※Verify heaters

Navigate to the temperature graph and type in 50 followed by enter in the “Tool” temperature target field. The extruder temperature in the graph should start to increase (within about 10 seconds or so). Then go to the “Tool” temperature drop-down box and select “Off”. After several minutes the temperature should start to return to its initial room temperature value. If the temperature does not increase, Please check the wiring.

Nozzle Preload and Filament Leakage Notice

During the initial setup of your Rapido 2.0 hotend, please be aware that some nozzles may have insufficient preload, which can cause filament leakage during printing. To prevent this, it is recommended to retighten the nozzle after the first heating of the hotend.

The kit includes two nozzles: a 0.4mm copper-plated (silver) nozzle and a pre-installed 0.6mm hardened steel nozzle. Ensure that you configure the correct nozzle diameter in both the printer.cfg file and your slicing software. Incorrect settings may result in under-extrusion or over-extrusion.

Perform the above steps again with the bed.

※Check Motor Operation

To verify that each stepper motor is operating correctly, send the following command in the terminal:

STEPPER_BUZZ STEPPER=stepper_x

The STEPPER_BUZZ command will cause the given stepper to move one millimeter in a positive direction and then it will return to its starting position. It will perform this oscillation ten times. we will verify direction again later, ideally all motors will be running correctly at the end of this test. See the list below for the expected motion for each command.

Note, if you have trouble seeing what direction a motor is rotating, try adding a small sharpy mark on the pulley. clockwise and counterclockwise are from the top down view looking at the X and Y motors.

Run this command for each of the motors:

stepper_x

The motor will rotate counterclockwise first, then back clockwise.

stepper_y

The motor will rotate counterclockwise first, then back clockwise.

stepper_x1

The motor will rotate counterclockwise first, then back clockwise.

stepper_y1

The motor will rotate counterclockwise first, then back clockwise.

stepper_z

The front left corner of the bed moves down, then back up.

stepper_z1

The back of the bed moves down, then back up.

stepper_z2

The front right corner of the bed moves down, then back up.

extruder

Movement: Direction will be tested later.

If the specified motor is not turning, please check the wiring and ensure that it is connected to the correct port.

※XY Endstop Check

Make sure that none of the X, Y endstops are being pressed. Then send a QUERY_ENDSTOPS command. The terminal window should respond with the following:

Send: QUERY_ENDSTOPS
Recv: x:open y:open z:triggered

If any of them say “triggered” instead of “open”, double-check to make sure none of them are pressed. Next, manually press the X endstop switch, send the QUERY_ENDSTOPS command again, and make sure that the X endstop says “triggered and the Y s stay open. Repeat with the Y endstops.

If it is found that one of the endstops has inverted logic (i.e. it reads as “open” when it is pressed and “triggered” when not pressed), Check if the Endstop is properly installed, the cables are secure and not damaged, and if they are connected to the correct port.

※XY Homing Check

At this point everything is ready to home X and Y.

Important: You need to be able to quickly stop the printer in case something goes wrong (e.g. the tool head goes the wrong direction). There are a few ways of doing this:

There is a red emergency stop icon in the lower left corner of the display. Click on it to see what happens—Klipper should shut down, but the Raspberry Pi and Mainsail should remain running, although disconnected from Klipper. Press "Connect" in the upper left corner of Mainsail, then send a FIRMWARE_RESTART command in the Mainsail terminal window to reboot the printer and get it running again.
Have a computer right next to the printer with the RESTART or M112 command already in the terminal command line in Mainsail. When you start homing the printer, if it goes in the wrong direction, quickly send the restart command and it will stop the printer.
As a “nuclear” option, power off the printer with the power switch if something goes wrong. This is not ideal because it may corrupt the files on the SD card and to recover would require reinstalling everything from scratch.

Once you have a testing procedure for stopping the printer in case of an issue, you can proceed to test the X and Y movements. Note: You need to test both X and Y to accurately determine what adjustments are necessary. First, send a G28 Y command. This will home the Y-axis only: the tool head should move to the back of the printer until it hits the Y endstop. Next, test the X-axis by sending a G28 X command; the tool head should move to the right.

Why move the Y-axis before the X-axis? Due to the AWD structure, the platform loses a portion of the area at the front on both sides. If the tool head home while near the front, it may collide with the motor.

Not moving in the expected direction?

Check that the XY motor cable and extension cable wire sequence are consistent, check that the extension cable is plugged into the port of the MANTA M8P and that the wire sequence is in the same order as shown in the wiring diagram, if not, adjust the wire sequence.

Not only is it not moving in the expected direction, but it is also making a strong noise and shaking?

Repeat the Check Motor Operation procedure to ensure that all motors are turning in the direction shown in the documentation.

※Check Fan

Note: If you are from the first batch of pre-sales or if your shipment was before August 29, 2024, please update your configuration. Copy the following settings and overwrite the existing fan configuration in printer.cfg before testing.

[gcode_macro M106]
gcode:
    {% set fan = 'fan' + (params.P|int if params.P is defined else 0)|string %}
    {% set speed = (params.S|float / 255 if params.S is defined else 1.0) %}
    SET_FAN_SPEED FAN={fan} SPEED={speed}

To add the following code to the CANCEL_PRINT and PRINT_END macros to turn off specific fans when the print is canceled or ends, you can update your printer.cfg file as follows:

[gcode_macro CANCEL_PRINT]
gcode:
    # Your other code...
    SET_FAN_SPEED FAN=fan0 SPEED=0
    SET_FAN_SPEED FAN=fan2 SPEED=0
    SET_FAN_SPEED FAN=fan3 SPEED=0
    # Your other code...

[gcode_macro PRINT_END]
gcode:
    # Your other code...
    SET_FAN_SPEED FAN=fan0 SPEED=0
    SET_FAN_SPEED FAN=fan2 SPEED=0
    SET_FAN_SPEED FAN=fan3 SPEED=0
    # Your other code...

This will ensure that fan0, fan2, and fan3 are turned off when a print is canceled or ends. Make sure to integrate these commands with the existing logic in your macros.

Identify all the fans inside the machine and check if the configured pins match the actual ones.

In the first batch of kits, the Driver_fan's wiring might be too short to reach the PF8 pin. You can move it to the PA4 fan port on the right and update the PF8 configuration in printer.cfg to PA4.(Don't forget to plug in the 24V jumper.)

Check Hotend_fan

Heat the hotend to above 50°C and check if the Hotend_fan is rotating correctly. When you stop heating and the temperature drops below 50°C, the fan will automatically turn off.

Check Controller_fan

Heat the heated bed to above 50°C and check if the Controller_fan starts rotating. When you stop heating and the temperature drops below 50°C, the fan will automatically turn off.

Check Driver_fan

Send the G28 X command, and after the X Stepper starts, observe if the Driver_fan begins to rotate. After turning off the motor using the M84 command, the fan will continue to run for 90 seconds before stopping.

Check Other fan

The Part cooling Blower, Auxiliary Part cooling Blower, and Fume_Pack can be directly controlled in Miscellaneous for on/off and speed settings. We will also configure them in the slicing software so that they can be activated when necessary.

※PID Tune Heated Bed

Move nozzle to the center of the bed and approximately 5-10mm above the bed surface, then run:

PID_CALIBRATE HEATER=heater_bed TARGET=100

It will perform a PID calibration routine that will last about 10 minutes. Once it is finished, type SAVE_CONFIG which will save the parameters into your configuration file.

PID Tune Hotend

Set the part cooling fans to 25% (M106 S64) and then run:

PID_CALIBRATE HEATER=extruder TARGET=245

It will perform a PID calibration routine that will last about 5 minutes. Once it is finished, type SAVE_CONFIG which will save the parameters into your configuration file.

※Cartographer Calibration

Calibration

Home the machine in X and Y:

G28 X Y

Position the nozzle in the center of the bed.In the case of the 350 model, the bed center position is 175,175

G0 X150 Y150

At this point, you might note that your Endstop Z is TRIGGERED, this is normal, and will be resolved once you run the next command.

Start the calibration process:

CARTOGRAPHER_CALIBRATE

You can either use the web interface to adjust the nozzle height from the bed, or TESTZ Z=-0.01 to lower it. Use a piece of paper or a feeler gauge to measure the offset. Once finished remove the paper/gauge and accept the position.

ACCEPT

Save the results to your config file.

SAVE CONFIG

Initial Tests

Home your printer.

G28

You can test the accuracy.

PROBE_ACCURACY

You can also measure the backlash of your Z axis

CARTOGRAPHER_ESTIMATE_BACKLASH

To make use of the backlash estimation that is given. You will get results spit out starting with

Median distance moving up

In this line will be a measurement called "delta" Take note of the value. Locate the configuration section marked:

backlash_comp: 2.01

Update this section with your new estimated backlash compensation.

※Z_TILT

The Trident uses automated bed leveling using 3 motors. There is a macro Z_TILT_ADJUST built into Klipper for that function. It is very similar to the QUAD_GANTRY_LEVEL used by V2, but supports 3 or more motors. Run the Z_TILT_ADJUST and it will probe each of the 3 points 3 times, average the readings, then make adjustments until the gantry is level.

If youa re using a printer which supports either Z_TILT you will need to ensure that your probe is positioned above the bed when performing this, open up your printer.cfg and find the appropriate section, for example your Z_TILT section may look like this:

Check the z_tilt speed. The initial parameter speed is too fast, which may cause missed steps. Please adjust the speed to 300.

[z_tilt]                 #300 Model
##  Use Z_TILT_ADJUST to level the bed.
##  z_positions: Location of toolhead
z_positions:
   -50, 18
   175, 398
   400, 18
points:
   50, 50                 # Point 1
   150, 250               # Point 2
   250, 50                # Point 3
##--------------------------------------------------------------------

speed: 300                 # Speed of Z tilt adjustment
horizontal_move_z: 2       # Z axis move speed for adjustments
retries: 10                # Number of retries for adjustment points
retry_tolerance: 0.0075    # Retry tolerance for adjustment accuracy

[z_tilt]                 #350 Model
##  Use Z_TILT_ADJUST to level the bed.
##  z_positions: Location of toolhead
z_positions:
   -50, 18
   175, 398
   400, 18
points:
   50, 50                 # Point 1
   175, 300               # Point 2
   300, 50                # Point 3
##--------------------------------------------------------------------

speed: 300                 # Speed of Z tilt adjustment
horizontal_move_z: 2       # Z axis move speed for adjustments
retries: 10                # Number of retries for adjustment points
retry_tolerance: 0.0075    # Retry tolerance for adjustment accuracy

You should in your console navigate to each point to ensure that your probe is not hanging off the edge, you can do this using a G0 command such as G0 X50 Y25 for point 1, or G0 X50 Y250 for point 2.

If at all points, Cartographer is safely over the bed, you should be good to go for running a Z_TILT .

BED_MESH

You can now run a Bed Mesh Calibration (I would advise doing either a Z_TILT.

BED_MESH_CALIBRATE

※Setting Z Offset

Before modifying your Z Offset, make sure that you have set your Z position to 0, to do this you can run the following command.

G1 Z0 F1500

Once you have done all of the above, it is worth re-calibrating the Z-Offset. This can be done in Mainsail or Fluidd using the graphical interface. OR you can use G-Code in the window to console to do

SET_GCODE_OFFSET Z_ADJUST=+0.01 MOVE=1

SET_GCODE_OFFSET Z_ADJUST=-0.01 MOVE=1

Once the offset has been perfectly calibrated apply that offset using the following command

Z_OFFSET_APPLY_PROBE

And now save your config.

※Extruder Calibration (e-steps)

Before the first print, make sure that the extruder extrudes the correct amount of material.

First, make sure the extruder is running the correct direction: heat the hotend, and extrude 10mm or so of filament:
- If the extruder pulls the filament in, all is well.
- If the filament gets pushed back out the top, , reverse the extruder in your printer.cfg by finding the [extruder] dir_pin, and adding a ! to the pin name. (if one is already present, remove it instead)
With the hotend at temperature, make a mark on the filament between the roll of filament and your extruder, between 120mm and 150mm away from the entrance to the extruder. Measure the distance from the entrance of the extruder to that mark.
In Mainsail, set the extrusion speed to 1mm/s, and extrude 50mm 2 times, (for a total of 100mm since Klipper doesn’t allow you to extrude more than 50mm at a time).
Measure from the entrance of your extruder to the mark you made previously.
- In a perfect world, assuming the mark was at 120mm, it would measure 20mm (120mm - 20mm = 100mm), but usually won’t be.
Update rotation_distance in the extruder section of the configuration file using this formula:
- New Config Value = Old Config Value * (Actual Extruded Amount/Target Extruded Amount)

Note: a higher configuration value means that less filament is being extruded.

Paste the new value into the configuration file, restart Klipper, and try again. Once the extrusion amount is within 0.5% of the target value (ie, 99.5-100.5mm for a target 100mm of extruded filament), the extruder is calibrated!

Typical rotation_distance values should be around 22.6789511 for Stealthburner
