- 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 stopping dobot magician, only after the signal light turns to dark, the power is off.
Here the operating routine:
plug in the Bluetooth/wifi/joysticks/ir detector/color detector module first
Power on dobot magician
Buzzing 3 times (2 times for wifi module, 4 times for joysticks), which means the initialization has completed.
Then control the dobot magician as usual
If fail to connect, please confirm:
1）check 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 are 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.
reset dobot magician and reconnect with Repetier host software.
Check if the plug of the thermosensitive resistor is loosened or the resistor is short-circuited or disconnected.
- 2.2 Signal Light Troubleshooting
After started Dobot Magician, if the signal light is red, please confirm:
if the dobot magician limited;
Return firmware for FPGA/MCU to test if there’s something wrong with the software
Cut off the power, take off the big arm and small arm’s cover, check the wire and socket if connect properly.
Cut off the power, take off the bottom case to replace the control panel to check if there’s something wrong with the control panel.
Please note: when you’re using 3d printing function, red light means there’s something wrong when reading the temperature of the heating head, please confirm:
- 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:
if the status signal light is off, please reburn FPGA/MCU firmware
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
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 the base panel.
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:
if the status signal is off, please reburn FPGA/MCU firmware
If the light is green, please check if the wiring of arms is loosened
If the wiring is ok, it may be caused by the driver module of this arm’s main board, please replace the main board.
- 2.4 Back to Zero Troubleshooting
Start dobot magician, click DobotStudio->Home to run Back to Zero. Normally, the base of the robot will turn left to the end then back to the preset zero point, the included angle of the small and big arm is 45 degree. If you have the following errors:
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 to reading head or code panel.
The base turns to left, when it backs to zero points, 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 the mother board
- 2.5 Save and Display Points Troubleshooting
The repeatability of dobot magician is 0.2mm, cut off the power and then power on, the positioning is 1 mm. If there is an error between save points and actually display, please follow the steps to enhance the precision:
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
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 the laser, if it can’t burn on paper, please confirm:
check if the wiring is right
Check if the laser is focused
Check if the reflectivity of the paper or the material you used is too high
If all of above is failed, please replace the laser head
- 2.7 Write and Draw Troubleshooting
DobotStudio can convert the 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
When you’re using Windows OS to control Dobot Magician, after connected with USB, if you have following errors:
Power on the dobot magician, the signal light is green, but turns to orange after plugin the USB, here you need to click the reset button in the base to turn it to green
Connect the USB to PC, the green light turns to red, it might be caused by driver, here is the solution:
if the PC OS is Win7 x 64 above, please stop the Digital Certificate, or skip it.
2) Revise the driver installation file
Find the CH341SER.INF in the installation category
Open it with notepad, find [CH341SER.NT.HW.AddReg]:
According to the tips to make notes as follow:
Uninstall the drivers with SETUP.EXE
Reinstall the driver, done
- 2.9 Leapmotion Troubleshooting
