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.
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.
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.
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:
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.
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.
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.
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:
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.
Hotend_fan
4010 FAN
EbbCan：gpio14
Hotend＞50℃
Controller_fan
6020 FAN ×2
PF9
Heatbed＞50℃
Driver_fan

Fan2 （Auxiliary part cooling fan）
12032 Blower fan
PA0
Manually or in slicing software
Fan3（Fume_Pack）
5015 Blower fan ×2
PF7
Manually or in slicing software
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.
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.
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.
Home the machine in X and Y:
Depending on the machine model, send the corresponding command below to move the toolhead above the center of the platform.
Send the following command to start the calibration process: CARTOGRAPHER_TOUCH METHOD=manual
Place an A4 sheet on the platform.
Use the web interface to adjust the nozzle height relative to the bed.
The two blue buttons on the left (--/-) lower the toolhead, bringing it closer to the platform.
The two blue buttons on the right (++/+) raise the toolhead, moving it farther away from the platform.
The value at the bottom indicates the increment or decrement for each adjustment, measured in millimeters (mm).
Continue adjusting until you feel noticeable resistance when pulling the A4 sheet, but not enough to damage it. Once this condition is met, click ACCEPT to save the parameters.
Wait a few seconds, then send SAVE_CONFIG to save the results to your configuration file.
Testing Cartographer Accuracy
Send the G28 command to home your printer.
Send PROBE_ACCURACY to test the accuracy. Cartographer will automatically perform 10 measurements and provide a summary of the results.for example：
Measuring Z-Axis Backlash
Run the command: CARTOGRAPHER_ESTIMATE_BACKLASH to estimate Z-axis backlash.
The results will be displayed, for example:
Look for the "delta" value in the output, which represents the measured backlash.
In your Printer.cfg, find the section labeled for backlash compensation and input the delta value as follows:
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.
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 .
Perform a homing.
If using a printer that requires Quad Gantry Level or Z Tilt Adjust, perform that.
Once that is finished, do another home or G28 Z
Initiate a threshold scan. This will determine your threshold for cartographer. The threshold will determine how much force is required to touch your bed consistently.
Start by doing the generic scan
This should start a touch process that will move the toolhead into a starting position and then lower until it touches the bed, repeating itself. Its okay if at first it doesnt touch the bed at all, this is completely normal. It will eventually start touching.
If however you get a final IDEAL result and it didnt touch the bed, start the process again OR adjust the parameters as follows where MIN= the found threshold value of the false positive.
Once it finds an excellent or ideal threshold and you've seen the nozzle touching the bed. It will stop this process and move on.
Now do a touch calibration with the new threshold.
If everything went correctly the touch test should pass and you can now finish by saving these variables to your config.
On the HEIGHTMAP interface, first home all axes, then click CALIBRATE. The machine will begin probing the heated bed and generate a graphical representation of the bed mesh.
The normal deviation range should be between 0.05-0.15mm. If the deviation is too large, check if the gantry frame profiles on both sides are aligned to the same horizontal plane.
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.
Before the first print, make sure that the extruder extrudes the correct amount of material.
Set the appropriate temperature for the hotend based on the type of filament. For example, for PLA, we use 210°C.
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).
Why is my interface greyed out and unclickable? This happens because the nozzle is either not heated or hasn’t reached the target temperature. The extrusion function is locked to prevent filament from being forcefully extruded without proper heating.
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
