    Hardware This chapter covers problems with the modules and addons of the Snapmaker 2.0, which includes the Enclosure, the Touchscreen, the 3D Printing Module, the Laser Module, and the Controller. For problems regarding the Snapmaker Luban, go to the next chapter.

  • Page 6: Touchscreen

    1. Update the firmware. For the latest version, visit https://forum.snapmaker.com/t/snapmaker-2-0-firmware-updates-and-downloads/5443/12. 2. Try a smaller G-code file. 3. Download the latest version of Snapmaker Luban from https://luban.xyz/, and try to generate the G-code file on Snapmaker Luban. Touchscreen Flashes The Touchscreen flashes as in the video: https://youtu.be/ZwH8v3V9ETo.

  • Page 7: Touchscreen Is Black

    1. Check whether the light at the back of the Controller is breathing. - If it breathes slowly, launch Snapmaker Luban, and try to connect your computer with the machine using a USB cable. If Luban has no problem connecting with and controlling the machine, then the Controller is fine. In this case, go to step 2.
  • Page 8 Hardware - If the test values are normal, then the Power Module and the DC power cable are fine, and the Controller is the problem. In this case, replacing the Controller might solve the problem. - If the values are not normal (pin 1 and pin 4 is 0 V or 3 V, for example), then replacing the Power Module and DC power cable might solve the problem.

  • Page 9: Linear Module

    • The end-stop switch is stuck. Actions 1. Connect the machine to your computer with a USB cable.  2. Launch the Snapmaker Luban. In the console, input M119, and check the status of the end-stop switch.  - If X_min or X_max is displayed as TRIGGERED, then the end-stop switch of the X Linear Module might be stuck.

  • Page 10: Slider (Carriage) Of Linear Module Comes Loose

    4. Check if the Linear Module works. If not, replacing the Linear Module might solve the problem. Slider (Carriage) of Linear Module Comes Loose Actions 1. Take the cover (the one with no cable attached) off from the Linear Module. You will need the 2.5 & 2.0 hex screwdriver.
  • Page 11 2. Slide the Slider off from the Linear Module. Note: One side of the bearings is adjustable.
  • Page 12 Hardware 3. Loosen the screw circled in the picture below. 4. Twist the bearing screw with an H3 hex screwdriver to adjust the distance between the bearings of two sides. The distance should be 34.29 mm. 5. Tighten the fastening screw first and then tighten the bearing screw. 6.

    Stainless Steel Strip of Linear Module Comes Loose Actions Please refer to the video on installing the stainless steel strip of the Linear Module at https://drive.google.com/ file/d/1tUFob6tJCzQmuNlBeBNeBUayOdsDXi4W/view?usp=sharing.

  • Page 14: 3D Printing

    Hardware 3D Printing 3D Printing Module Isn't Detected If you turn on the machine, and the Touchscreen displays an error message Snapmaker tech-team, then it might be that the 3D Printing Module is not detected by the machine. Possible Causes • The toolhead cable is broken. • The Linear Module or the Controller is broken.

  • Page 15: First Layer Doesn't Stick To Print Sheet

    2. Remove all the cables of the Linear Modules from the Controller, and see if the Printing Module, Laser Module, and CNC Module can be detected. - If yes, then it means one or more Linear Modules are disrupting Controller Network Area (CAN) communication.

  • Page 16: 3D Printing Module Pushes Into Print Sheet

    Hardware 2. In Luban, go to Printing Settings to set the Initial Layer Print Speed as 8 mm/s and try again. 3. Try another filament. 3D Printing Module Pushes into Print Sheet The 3D Printing Module clashes against the Print Sheet during calibration or printing. Possible Causes •...

  • Page 17: Filament Runout

    2. Check whether the screws on the aluminum grid platform face downward as illustrated. If not, re-install all the screws on the platform.   3. If the problem persists, check whether the probe sensor is working properly. For detailed instructions, see Adjustprobe/proximitysensor of 3DPrinting Module.  4.

  • Page 18: Filament Won't Load

    Hardware Possible Causes • The filament switch is broken. Actions   1. Remove the fan: https://youtu.be/e2L_Y_HZGgA. 2. Adjust the filament switch: https://youtu.be/_KAQvMNoJUQ. Filament Won't Load Possible Causes • The nozzle is jammed. • The filament is bent or compromised. • The 3D Printing Module or Controller is broken. Actions 1.
  • Page 19 4. On the Touchscreen, go to Control > Nozzle. 5. Wait for the nozzle to heat up until you can tap the Load or Unload button. Make sure the nozzle temperature matches the working temperature of the filament you are using (ABS generally requires a higher temperature than PLA, for example). Tap Load to see if the gear inside the 3D Printing Module rotates. - If it does, then use a metal stick to poke the feeding hole (see picture below).

  • Page 20: Blobs On Nozzle

    Hardware - If it doesn't, then check whether the Laser Module works. - If the Laser Module works well, then the Printing Module itself is broken, replacing it might solve the problem. - If the Laser Module won't emit blue laser light (or won't stop emitting it, for that matter), then something is wrong with the Controller.
  • Page 21 Actions 1. Replace the hot end before trying any of the following steps. A spare hot end is included in the box. For how to change the new hot end kit, see https://youtu.be/2anRrb_R63o. Note: If it's hard to remove the blobs from the current hot end, heat the nozzle up to 230 ℃ and try again. 2.

  • Page 22: Nozzle Temperature Is Too High

    Hardware ℃  Nozzle Temp Touchscreen Shows a -30 Possible Causes • The thermistor is dislocated. • The hot end is broken.  Actions 1. Check if the thermistor (see circled in picture below) is securely seated in the hole. Plug it back in if it is not. If the problem persists, try the next step.

  • Page 23: Heated Bed Won't Heat Up

    2. If the problem persists, replacing the 3D Printing Module might solve the problem. Heated Bed Won't Heat up The Heated Bed won't heat up when you set the target temperature on the Touchscreen or when you start a print. Possible Causes •...
  • Page 24 Hardware 2. Get a multimeter, unplug the Heated Bed cable from the Controller, and measure the resistance of the Heated Bed. The resistance should be in the range of 60 KΩ – 130 KΩ. If the test value is out of the range, then the Heated Bed might be broken, replacing it might solve the issue. 3.

  • Page 25: Printing Module Clashes Against The Print Sheet During Calibration

    1. Download and install the latest version of firmware from     https://forum.snapmaker.com/t/snapmaker-2-0-firmware-updates-and-downloads/5443/12. See if this solves the problem. If not, follow the steps below to test your probe sensor. 2. Start auto-calibration on the Touchscreen. The 3D Printing Module will go back to its home position and then move down.
  • Page 26 Hardware 4.3 Loosen the screw of the probe sensor so that it can be adjusted. 4.4 Find a credit card (or anything with a height of about 1 mm). Move the module down until the nozzle tip touches the Print Sheet; then put the card under the probe sensor so that the sensor is approximately 1 mm higher than where the nozzle tip is.
  • Page 27 4.7 Redo calibration following the prompts on the Touchscreen. Keep the machine connected to the computer the whole time.

  • Page 28: Laser

    Hardware Laser Laser Calibration Fails If the Laser Calibration doesn't go well, the Touchscreen will display Failed.  Possible Causes • The laser is too high. Actions Two options are available. 1. Redo auto focus. Tap Failed, slide the scale left to select the leftmost line, and tap Save. The screen should go back to the main menu.

  • Page 29: Laser Is Discontinuous Or Weak

    2. Change the Laser Height manually. On the Touchscreen, tap Failed > Settings > Laser > Adjust Laser Height. Set the Laser Height to 23.0mm and then recalibrate. If the Touchscreen keeps showing Failed, and several lines fail to be burned, then lower the laser height (to 21.5 mm or 19 mm, for example), and try again. Laser Is Discontinuous Or Weak The Laser Module emits weak light and doesn't engrave at its full power, and therefore the module can't finish Auto Focus.

  • Page 30: Machine Is Stuck In Processing During Auto Focus

    Actions Twist to remove the bottom half of the laser shade, and see if the problem persists. If so, please export the log file from the Touchscreen to your USB drive and send it to support@snapmaker.com for further investigation. For how to export the log file, see https://drive.google.com/file/d/189CIUW4D4o_Qm2mY2j63N3rKzn7n3zZp/view. ...
