Dobot Magician Hardware Troubleshooting

2.1 Bluetooth/Wifi/Joysticks Troubleshooting

Please make sure that the Dobot Magician has already cut off the power before connect or disconnect the external devices like bluetooth, wifi, joystick , IR detector, color detector and so on. Otherwise it can damage dobot magician to some extent. When stop dobot magician, only after the signal light turns to dark, the power is off.

Here the operating routine:

  1. plug in the bluetooth/wifi/joysticks/ir detector/color detector module first
  2. Power on dobot magician
  3. Buzzing 3 times (2 times for wifi module, 4 times for joysticks), which means the initialization has completed.
  4. Then control the dobot magician as usual

If fail to connect, please confirm:

1check the module’s signal light, if it’s still dark, it may be caused by the module, please replace a new module;

2)  if the module’s signal light is on, please check if there is any other bluetooth devices disturbed (especially when you’re on the exhibitions.)

3) if the module’s signal light is on, please check if the wifi and pc belong to the same router and if the login name and password are right.

4) if the module’s signal light is on, please check if the joystick can open.

5) if all of above is failed, please replace a new module or new dobot magician to test.

2.2 Signal Light Troubleshooting

After started Dobot Magician, if the signal light is red, please confirm:

  1. if the dobot magician limited;
  2. Return firmware for FPGA/MCU to test if there’s something wrong with the software
  3. Cut off the power, take off the big arm and small arm’s cover, check the wire and socket if connect properly.
  4. Cut off the power, take off the bottom case to replace the control panel to check if there’s something wrong with control panel.

Please note: when you’re using 3d printing function, red light means there’s something wrong when read the temperature of heating head, please confirm:

  1. reset dobot magician and reconnect with Repetier host software.
  2. Check if the the plug of  thermosensitive resistor is loosened or the resistor is short-circuited or  disconnected.

2.3 Big and Small Arm Troubleshooting

2.3.1 start dobot magician, if you found there is any robotic arm unable to lock while the small arm can be unlocked, please confirm:

  1. if the status signal light is off, please reburn FPGA/MCU firmware
  2. If the light is green, please make sure that if the motor wire of big and small arm as well as base panel is loosened or not
  3. If the light is on, while some of the motors can be unlocked, it probably caused by the driver module, please replace the motherboard of base panel.
  4. If the light is orange, all motors can be unlocked,  please make sure that if the wire of 12V power charger is loosened, if there’s no problem with wiring, but can’t burn firmware successfully, please replace the motherboard.

2.3.2 start dobot magician, one of the arms can’t be locked, at the same time, the small arm can’t be unlocked, please confirm:

  1. if the status signal is off, please reburn FPGA/MCU firmware
  2. If the light is green, please check if the wiring of arms is loosened
  3. If the wiring is ok, it may be caused by the driver module of this arm’s main board, please replace main board.

2.4 Back to Zero Troubleshooting

Start dobot magician, click DobotStudio->Home to run Back to Zero. Normally, the base of robot will turn left to the end then back to the preset zero point, the included angle of small and big arm is 45 degree. If you have the following errors:

  1. the base turns to left always, continually hit the base, please replace the motherboard, if it’s still not working, it’s probably caused by damage of read head or code panel.
  2. Base turns to left, when it backs to zero point, the included angle of small and big arm becomes smaller and hit the base finally, please click DobotStudio to control base, big arm, small arm.

I: if it can be controlled successfully, please check if you ever changed the preset home point, if yes, please reset the home point to (250, 0, 0) to test again.

ii: if it can be controlled successfully, but the reading of small arm or big arm is abnormal, please check if the wiring is loosened.

iii: if fail to control, please take off the base cover to change mother board

2.5 Save and Display Points Troubleshooting

  1. power on-> light turns to green for 30 seconds, when the sensor stays stable click Home -> after the back to zero completed, start to save points
  2. power on-> light turns to green for 30 seconds, when the sensor stays stable click Home -> after the back to zero completed, start to display points

2.6 Laser Engraving Troubleshooting

First time to use laser, if it can’t burn on paper, please confirm:

  1. check if the wiring is right
  2. Check if the laser is focused
  3. Check if the reflectivity of the paper or the material you used is too nigh
  4. If all of above is failed, please replace the laser head

2.7 Write and Draw Troubleshooting

DobotStudio can convert image to svg file to write and draw, while sometimes the writing looks not smooth or even stops for good. It’s always caused by too many noisy points, please follow up the steps to lower down the converting threshold value.

2.8 USB Driver Troubleshooting

3D Printing Troubleshooting

  • 3.1 Installation

Make sure that the PTFE tube and filament are installed to the bottom of the heating head as follow, otherwise, they’re some troubles in discharging.

Extruder installation as follows:

  • 3.2 Fail to connect Repetier Host, Fail to control XYZ

After connected with Dobot Magician, the DobotStudio can’t control XYZ, please try:

Check the Printer Settings as follow:

Press reset to reconnect Dobot Magician

Resend M415 or press Key button to get coordinates

Reburn 3D printing firmware

  • 3.3 Fail to open Slic3r Setting Window

1) download Repetier Host to install again: https://www.repetier.com/download-now/

2) download the latest version of Slic3r here: https://slic3r.org/, open the slices independently, then import to Repetier Host to print.

  • 3.4 Dobot Magician freezes after the 3D Printing starts

With Repetier Host, the Dobot Magician starts to heat and slice, but when it starts to 3D Print the first layer, the jet freezes or pauses from time to time, which means it moves to the adjusting mode. Please find the confirm button in the right corner of the control panel, click it one or two times to exit the adjusting mode.

  • 3.5 3D Printing Extruder doesn’t move

With Repetier Host, the Dobot Magician starts to heat and slice, but when to test the extruder, the motor doesn’t move.

1) please make sure the heating head temperature already reached 200 degrees, cause the extruder won’t start before the temperature reaches 180 degrees.

2) If the temperature reaches 200 degrees while it still doesn’t work, check the motor first. If the motor is broken it may be caused by defective motor or motherboard, please replace the Dobot Magician or motor to test.

  • 3.6 Temperature Troubleshooting

After connected with Dobot Magician, generally speaking, the temperature should be the same with normal room temperature if it doesn’t start to heat. However, if it shows 270 to 350 degree or above, which means the thermistor short circuited because of improper installation as follow:

Solution: screw down the bolt, take out the thermistor, separate the pins, test the temperature, then put it back and screw up. In the same way, if it shows 0 degrees for good, please make sure that the Dobot Magician had already connected the Host successfully.

  • 3.7 Extruder Nozzle Clogged

When you 3d print the first layer, make sure there is some space between extruder and heating bed, which helps filament sticks to the heating bed smoothly and extruder nozzle won’t be clogged.

If space is limited, it results in extruder nozzle clogged, the feeding gear of extruder clicks with big sound because of clogged extruder nozzle with resistance.

Solution:

1) try to extrude the filament manually

Heat the extruder to 200 degrees, press strut, push the filament to the extruder, if the filament flows from the nozzle, it dredges.

2) Reinstall filament

If the filament still doesn’t move, after heated, pull the filament from the extruder, cut down the melt or damaged parts with tools. Reinstall the filament to test if it works.

3) Clean nozzle

If the filament still can’t extrude out, it’s necessary to take apart the heating head to clean nozzle.

Start to heat, plug to the heating head with iron wire or other tools to discharge the melted filament; after heated, take apart the heating head to clean one by one, then assemble it.

  • 3.8 Tilt 3d printing object

If the 3d printing object is tilt, please switch to dobotfirmware and calibrate the Dobot Magician, then test again.

  • 3.9 Fail to import the setting file

Import .ini setting file under attachment file, if you have following error ” The selected preset does not exist anymore”. It’s caused by failing to use Chinese file route with 3d Printing software, please install DobotStudio installation file move to English file and reopen to solve.
